Description

stroller

technical field

The present invention relates to a foldable stroller capable of swinging a handle.

Background technique

For example, as disclosed in CN102248961A, the baby carriage used when carrying infants to go out is available. Most strollers can be folded in consideration of convenience during storage and/or carrying. In addition, strollers that can swing handles between a first position and a second position are also gaining popularity.

In the stroller disclosed in CN102248961A, the handle can swing between a rear pushing position and a facing pushing position. In the rear push position, the handle is located on the rear side of the infant from which the protector pushes the stroller. On the other hand, in the facing push position, the handle is located at a position facing the infant, and the protector pushes the stroller from the side facing the infant.

However, in order to fold the stroller disclosed in CN102248961A, it is necessary to return the handle to the rear pushing position in advance. Also, for strollers that unfold from a folded state, the handle is usually in the rear push position. Therefore, in order to push the stroller while facing the infant, it is also necessary to swing the handle to the facing pushing position. On the other hand, in general, when using a stroller for a young baby, the stroller is often pushed from the side facing the baby. At this time, every time the baby carriage is folded and every time the baby carriage is unfolded, it is necessary to switch the swing position of the handle.

In the present embodiment, the stroller 10 is configured to be foldable as widely used. In addition, in the stroller 10 of this embodiment, by swinging the handle 50 relative to the main body frame 12, the following two actions can be realized: the operator (protector) holds the handle 50 from the back side of the infant to manipulate the stroller 10 to make the baby carriage 10 walk in such a way that the baby faces forward in the direction of travel; The stroller 10 is moved so that the leg side becomes forward in the traveling direction.

However, in this specification, the terms "front", "rear", "upper", "lower", "front-rear direction" and "up-and-down direction" with respect to the stroller and its constituent elements shall be used unless otherwise specified. Refers to "front", "rear", "upper", "lower", "front-rear direction" and "upper-lower direction" based on infants and toddlers riding in the unfolded stroller and its components. More specifically, the "front-back direction" refers to the direction connecting the lower left and upper right of the paper in FIG. 1 , and corresponds to the left-right direction of the paper in FIG. 2 . In addition, unless otherwise specified, "front" refers to the side facing the infant riding on the vehicle, and the lower left side of the paper in FIG. 1 and the left side of the paper in FIG. 2 are the front side. On the other hand, the "up-and-down direction" refers to a direction perpendicular to the front-rear direction and perpendicular to the ground contact surface. Therefore, when the ground plane is a horizontal plane, the "up and down direction" means the vertical direction. In addition, "horizontal direction" means a width direction, and is a direction orthogonal to both the "front-rear direction" and the "up-and-down direction".

First, the stroller main body 11 will be described as the overall structure of the stroller. As shown in FIG. 1 , the stroller 10 according to the present embodiment has a generally symmetrical structure centered on a transverse central plane along the front-rear direction as a whole. As described above, the stroller main body 11 has the main body frame 12 and the handle 50 .

Similarly, the left second link 25 is formed by the side 26a of the left frame member 26 and the left front connecting piece 27 and the rear connecting piece 28 fixed to the left side 26a.

As shown in FIG. 1 , in the illustrated example, the third link 30 has a main shaft member 31 rotatably connected to the rear leg 16 , and an end member 32 fixed to an upper end portion of the main shaft member 31 . The main shaft 31 is made of, for example, a metal pipe. The end member 32 is made of, for example, a resin molded product. The main shaft member 31 is rotatably connected to the rear leg 16 at a lower end portion. The end piece 32 is connected to the first link 20 and the second link 25 .

Here, FIGS. 9 and 10 are perspective views showing the periphery of the first link 20 from inside in the width direction. As shown in FIGS. 9 and 10 , in the illustrated example, the first link 20 , the second link 25 , and the third link 30 are rotatably connected to each other using the same shaft member 34 . The shaft member 34 passes through the main link member 21 of the first link 20 , the end member 32 of the third link 30 , and the rear link member 28 constituting the second link 25 . With this configuration, the first link 20 , the second link 25 , and the third link 30 are mutually rotatable around the same axis defined by the shaft member 34 .

In addition, in the illustrated example, as shown in FIGS. 1 and 2 , the main body frame 12 further includes a base frame 41 , an upper frame 42 , and a connection frame 43 that connects the base frame 41 and the upper frame 42 . A base fabric material (not shown) is stretched on the frame member 26 and the base frame 41 . The base fabric supports a cushioning seat material (not shown) together with the frame material 26 , the base frame 41 , the upper frame 42 , and the connection frame 43 . Both the base frame 41 and the upper frame 42 are formed in a U-shape.

As shown in FIGS. 9 and 10 , the base frame 41 penetrates through the shaft member 34 at both ends thereof. Furthermore, the base frame 41 is rotatable (swingable) with respect to the frame member 26 and/or other components. The upper frame 42 is rotatably (swingably) connected to the rear end portion of the armrest 19 at both ends thereof. The axis of rotation of the upper frame 42 relative to the armrest 19 is located on the same line as the axis of rotation of the first link 20 relative to the armrest 19 . Between the base frame 41 and the upper frame 42, a pair of connection frames 43 are provided so as to be spaced apart in the lateral direction. The connection frame 43 is rotatably connected to the base frame 41 and the upper frame 42 at both ends thereof.

As shown in FIG. 1 , the main body frame 12 has, as components extending in the lateral direction, a front link 15 connecting a pair of front legs 14 and a rear link 17 connecting a pair of rear legs 16 . The front link 15 functions as a pedal. In addition, between the pair of rear link members 28, a center link member 29 is provided. Lateral deformation of the stroller 10 can be suppressed by the front link 15 , the rear link 17 , and the center link 29 . Furthermore, a flexible protective member 38 is detachably provided between the pair of armrests 19 .

The main body frame 12 having the above configuration can be folded by operating the constituent elements as will be described later. On the other hand, the main body frame 12 is provided with a mechanism for restricting relative movement between the components. By providing this mechanism, it is possible to effectively prevent an undesired folding operation.

Specifically, as shown in FIGS. 9 and 10 , a state maintaining member 45 that restricts the folding operation of the stroller 10 from the unfolded state to the folded state is provided on the main body frame 12 . The state maintaining member 45 is movable between a restricted position where the folding operation of the baby carriage 10 is restricted, and a release position where the folding operation of the baby carriage 10 is enabled. In the illustrated example, the state maintaining member 45 is supported by the main link element 21 of the first link 20 . The movement of the state maintaining member 45 between the restriction position and the release position is movement along the longitudinal direction of the main link 21 .

As shown in FIG. 10 , the state maintaining member 45 has a main body portion 46 attached to the main link 21 , and a restrictive engagement protrusion 47 protruding from the main body portion 46 and a support plate 48 . The limiting engagement protrusion 47 protrudes laterally inward from the main body portion 46 . On the other hand, on the end member 32 of the third link 30 , a restriction engagement recess 33 capable of engaging with the restriction engagement protrusion 47 is formed. As shown in FIG. 9 , when the state maintaining member 45 slides downward relative to the first link 20 , the restricting engagement protrusion 47 of the state maintaining member 45 is accommodated in the restricting engagement recess 33 of the third link 30 . . In the state shown in FIG. 9 , the first link 20 supporting the state maintaining member 45 and the third link 30 engaged with the state maintaining member 45 cannot rotate relative to each other. Therefore, when the restricting engagement protrusion 47 of the state maintaining member 45 is engaged with the restricting engagement recess 33 of the third link 30 , the stroller 10 is maintained in the unfolded state, and the stroller 10 cannot be folded. That is, the position of the state maintaining member 45 shown in FIG. 9 is a restricted position of the state maintaining member 45 .

On the other hand, as shown in FIG. 10 , when the state maintaining member 45 slides upward with respect to the first link 20 , the restriction engagement protrusion 47 is pulled out from the restriction engagement recess 33 of the third link 30 . Then, when the engagement between the restriction engagement projection 47 and the restriction engagement recess 33 is released, the first link 20 and the third link 30 can relatively rotate, and the stroller 10 can be folded. That is, the position of the state maintaining member 45 shown in FIG. 10 is the released position of the state maintaining member 45 .

The main body portion 46 of the state maintaining member 45 is biased from the release position (see FIG. 10 ) toward the restriction position (see FIG. 9 ) by the first biasing member 49 as shown in FIG. 9 . By using the urging force from the first urging member 49 in this way, as long as no external force is actively applied, the folding operation of the stroller 10 is further reliably restricted. That is, by using the first urging member 49, it is possible to effectively prevent an undesired folding operation of the stroller 10 from being started due to a malfunction.

The handle 50 is connected to the main body frame 12 described above so as to be able to swing. In the illustrated example, the handle 50 includes a handle body 51 swingably attached to the main body frame 12 , a remote operation device 52 provided on the handle body 51 , a holder 55 , and an operation member 60 .

As shown in FIG. 1 , the handle main body 51 includes a pair of shaft portions 51a extending substantially parallel to each other and an intermediate portion 51b connecting the pair of shaft portions 51a. The handle main body 51 has a substantially U-shape as a whole. The handle 50 is rotatably (swingably) connected to the main body frame 12 at both ends of the U-shape. As shown in FIGS. 9 and 10 , the handle main body 51 is rotatably connected to the main body frame 12 using the shaft member 34 . Therefore, the first link 20 , the second link 25 , the third link 30 , the base frame 41 , and the handle 50 are rotatable relative to each other around the same axis defined by the shaft member 34 .

In this stroller main body 11, the handle 50 is capable of a first position (rear pushing position) tilted rearward with respect to the vertical axis when viewed from the side and a second position (facing pushing position) tilted forward with respect to the vertical axis. swing between. In FIG. 1, the handle 50 is configured in a first position. In FIG. 2, the handle 50 is configured in a second position. Here, the main body frame 12 is provided with position holding members 35 and 36 capable of engaging with a holding body 55 provided on the handle 50 . The handle 50 is held at the first position by the engagement of the holding body 55 with the first position holding member 35 . The handle 50 is held at the second position by the engagement of the holding body 55 with the second position holding member 36 .

In the illustrated example, a pair of first position holding members 35 are respectively fixed above the respective first links 20 as shown in FIG. 2 . In addition, a pair of second position holding members 36 is fixed to the front of each armrest 19 as shown in FIG. 1 . The first position holding member 35 and the second position holding member 36 can be configured in the same manner. As also shown in FIG. 18 , each position holding member 35 , 36 protrudes outward in the width direction as a protrusion having an enlarged diameter portion at the tip.

In the illustrated example, a pair of holders 55 are supported by each shaft portion 51 a of the handle main body 51 . The holder 55 is movable relative to the handle body 51 along the longitudinal direction of the portion of the handle body 51 where the holder 55 is provided. As shown in FIG. 2 , on each shaft portion 51 a of the handle main body 51 , a pair of stoppers 51 c are separately provided along the longitudinal direction of the shaft portion 51 a. The stopper 51c is formed as a portion enlarged in diameter with respect to the shaft portion 51a. The pair of stoppers 51c regulates the movable range of the holder 55 . The holder 55 is movable along the longitudinal direction of the shaft portion 51 a in a region that becomes between the pair of stoppers 51 c.

As shown in FIGS. 6 and 7 , the holder 55 has a cylindrical body portion 56 through which the shaft portion 51 a passes, and a guide portion 57 and an engaging portion 58 supported by the cylindrical body portion 56 . As shown in FIG. 7, the engaging part 58 has the support part 58a opened downward. As shown in FIG. 5 , since the engaging portion 58 covers the position holding members 35 and 36 from above, the relative movement of the holding body 55 and the position holding members 35 and 36 in the direction perpendicular to the longitudinal direction of the shaft portion 51 a is controlled. limit, the handle 50 remains at the first position or the second position. As shown in FIG. 6 , each holder 55 has a pair of guide portions 57 located on both sides of the engaging portion 58 . As shown in FIG. 2 , the cylindrical main body portion 56 is located between a pair of guide portions 57 separated in the front-rear direction. When the handle swings between the first position and the second position, the guide portion 57 provided adjacent to the engaging portion 58 contacts the position holding members 35 and 36 at a position closer to the front end than the engaging portion 58 . The guide portion 57 has a guide surface 57 a that contacts the position holding members 35 , 36 . The guide surface 57a becomes an inclined surface. When the guide surface 57 a comes into contact with the position holding members 35 and 36 , the holding body 55 is separated from the position holding members 35 and 36 along the longitudinal direction of the shaft portion 51 a and moves upward.

Here, the handle 50 further has a second urging member 54 that urges the holder 55 . The second urging member 54 urges the holder 55 in a direction approaching the position holding members 35 , 36 along the longitudinal direction of the shaft portion 51 a. That is, the second urging member 54 acts on the holder 55 so as to maintain the engagement between the holder 55 and the position holding members 35 , 36 .

The second urging member 54 is formed of, for example, a member that generates elastic force depending on its material or shape. In the illustrated example, the second urging member 54 is formed of a compression spring. In addition, in the illustrated example, the handle 50 further has a cover plate 53 provided on the handle main body 51 . As shown in FIGS. 5 and 6 , the cover plate 53 forms a housing space rs between the cover plate 53 and the handle body 51 . The second urging member 54 is arranged in the storage space rs. As shown in FIG. 8 , a groove 53 a is formed in the cover plate 53 . As shown in FIG. 5 , the groove 53 a extends along the longitudinal direction of the shaft portion 51 a of the handle main body 51 . The storage space rs communicates with the outside through the groove 53a. On the other hand, as shown in FIGS. 5 to 7 , the holder 55 has a protruding portion 56a protruding into the storage space rs through the groove 53a. As shown in FIG. 7 , the protruding portion 56 a protrudes from the cylindrical main body portion 56 toward an internal space defined by the cylindrical main body portion 56 . As shown in FIG. 5 , the protruding portion 56 a supports the lower end of the compression spring constituting the second urging member 54 . Therefore, the protruding portion 56 a is pressed downward by the second biasing member 54 . In addition, in the illustrated example, the lower stopper 51c is formed as a part of the cover plate 53 .

Next, the operation member 60 will be described. As shown in FIGS. 9 and 10 , the operating member 60 is movably provided on the handle body 51 . As shown in FIGS. 9 and 10 , the operation of the operating member 60 causes the state maintaining member 45 to operate. That is, the operation member 60 is provided along with the installation of the state maintaining member 45 .

The operating member 60 is movable between the non-operating position shown in FIG. 9 and the operating position shown in FIG. 10 along the longitudinal direction of the shaft portion 51 a of the handle body 51 where the operating member 60 is provided. The operation member 60 is biased from the operation position side to the non-operation position by the third biasing member 64 (see FIG. 9 ) housed in the shaft portion 51 a of the handle 50 . That is, the operation member 60 is located at the non-operation position below the operation position by the urging force from the third urging member 64 when no external force is applied. As an example, the operation member 60 is connected to the remote operation device 52 (see FIG. 1 ) provided on the middle portion 51b of the handle 50 via an operation transmission tool not shown. In addition, the operation member 60 can be moved from the operation position to the non-operation position by operating the remote operation device 52 .

As shown in FIGS. 15 and 16 , the operation member 60 has an operation base 61 and an operation protrusion 62 protruding from the operation base 61 . Here, FIG. 15 is a perspective view showing the operation member 60 from outside in the width direction, and FIG. 16 is a plan view showing the operation member 60 from inside in the width direction. As shown in FIG. 9 , the operation base 61 is attached to the shaft portion 51 a of the handle main body 51 . As can be understood from a comparison of FIGS. 9 and 10 , the operation base 61 is slidable relative to the shaft portion 51 a of the handle main body 51 along the length direction of the shaft portion 51 a. Also, the operation protrusion 62 protrudes from the operation base 61 toward a direction perpendicular to the longitudinal direction of the portion of the handle body 51 where the operation base 61 is provided, more specifically, inward in the width direction. On the other hand, as shown in FIG. 9 , the support plate 48 of the state maintaining member 45 protrudes outward in the width direction from the main body portion 46 .

Then, when the operation member 60 moves from the non-operation position to the operation position, the operation protrusion 62 contacts the support plate 48 of the state maintenance member 45 from below, and presses the state maintenance member 45 from the restriction position toward the release position. That is, when the handle 50 is located at the first position, the state maintaining member 45 can be moved from the restriction position to the release position by moving the operation member 60 from the non-operation position to the operation position when the handle 50 is located at the first position. Thereby, the relative rotation of the 1st link 20 with respect to the 3rd link 30 can be performed.

In particular, as shown in FIGS. 11 to 14 , the operation member 60 can press the state maintaining member 45 by moving the handle body 51 of the handle 50 at the first position to move from the restriction position to the release position, and by The state maintaining member 45 can also be pressed and moved from the restriction position to the release position by operating the handle main body 51 of the handle 50 at the second position. Here, FIGS. 11 to 14 are side views showing the vicinity of the installation position of the first link 20 . However, for ease of understanding, in FIGS. 11 and 12 , the lower part of the first link 20 and the state maintaining member 45 are shown by dotted lines, and the handle main body 51 and the operation member 60 are shown by solid lines.

As best shown in FIG. 16 , the operating protrusion 62 of the operating member 60 has a first contact surface 62 a and a second contact surface 62 b. First, the first contact surface 62a is arranged at a position shifted along the longitudinal direction of the shaft portion 51a with respect to the swing axis sa of the handle body 51 . As shown in FIGS. 11 and 12 , when the handle 50 is arranged at the first position, the shaft portion 51 a of the handle 50 extends substantially parallel to the main link member 21 of the first link 20 . Therefore, if the operation member 60 moves from the non-operation position to the operation position, that is, if the operation member 60 moves upward along the shaft portion 51a of the handle 50 at the first position, the first contact surface 62a of the operation member 60 moves from below It abuts against the support plate 48 of the state maintaining member 45 , and can press the support plate 48 upward along the first link 20 .

On the other hand, the second contact surface 62b is an inclined surface that is inclined with respect to the moving direction of the operation member 60 from the non-operation position (see FIG. 13 ) to the operation position (see FIG. 14 ) and is inclined from the movement of the operation member 60 . The front side of the direction toward the rear side is separated from the handle main body 51 , and the moving direction of the operation member is a direction from the non-operation position toward the operation position. In other words, as best shown in FIG. 16 , the second contact surface 62 b is inclined rearward from the swing axis sa toward the lower side with respect to the length direction ld of the shaft portion 51 a. Therefore, as shown in FIGS. 13 and 14 , when the handle 50 is swung forward and placed at the second position, the second contact surface 62 b is extended from the main link 21 of the first link 20 in the longitudinal direction. The lower side faces the support plate 48 of the state maintaining member 45 . In particular, as shown in FIGS. 13 and 14 , when the handle 50 is disposed at the second position, that is, if the shaft portion 51 a of the handle main body 51 is inclined upward and forward, the second contact surface 62 b is along the Extend generally in the fore-and-aft direction. When the operation member 60 moves from the non-operation position to the operation position, the second contact surface 62b of the operation member 60 can contact the support plate 48 of the state maintaining member 45 from below to press the support plate 48 upward.

In the illustrated example, the operating member 60 located at the non-operating position is separated from the state maintaining member 45 . That is, in a state where the handle 50 is at the first position and the holding body 55 is at the non-operation position, that is, in the state shown in FIG. 11 , the operating member 60 is separated from the holding body 55 . In addition, in a state where the handle 50 is at the second position and the holding body 55 is at the non-operation position, that is, in the state shown in FIG. 13 , the operating member 60 is separated from the holding body 55 . On the other hand, as shown in FIG. 16, the operation protrusion 62 of the operation member 60 also has a convex surface 62c located between the first contact surface 62a and the second contact surface 62b. The distance dx from the swing axis sa of the handle 50 relative to the main body frame 12 to the convex surface 62c is longer than the distance dy from the swing axis sa to the portion 62a1 of the first contact surface 62a adjacent to the convex surface 62c and is longer than the distance dx from the convex surface 62c. The distance dz from the swing axis sa to the portion 62b1 of the second contact surface 62b adjacent to the convex surface 62c is long. That is, the convex surface 62c protrudes more than the adjacent 1st contact surface 62a and the 2nd contact surface 62b.

Next, the wheel holding unit 70 fixed to the legs 14 and 16 of the stroller main body 11 will be described. The wheel holding unit 70 fixed to the front leg 14 holds the wheel rotatably and holds the wheel also steerable. That is, the wheel holding unit 70 fixed to the front leg 14 constitutes a so-called caster. The wheel holding unit 70 fixed to the rear leg 16 holds the wheel in a rotatable manner, and may hold the wheel in a steerable manner similarly to the wheel holding unit 70 fixed to the front leg 14 . When both the wheel holding unit 70 fixed to the front leg 14 and the wheel holding unit 70 fixed to the rear leg 16 are configured as casters, according to the swing position of the handle 50, the wheel located on the front side in the direction of travel of the stroller 10 The turning of the wheels in the holding unit 70 may be allowed, and the turning of the wheels in the wheel holding unit 70 located on the rear side in the traveling direction of the stroller 10 may be restricted. Switching between permitting and restricting the steering of the wheels may be performed manually, or may be performed automatically by swinging the handle 50 as disclosed in JP2002-284015A, for example.

The operation of the stroller 10 configured as above will be described. The stroller 10 described above can be used with the handle 50 fixed in either of the first position shown in FIG. 1 and the second position shown in FIG. 2 . When the handle 50 is held at the first position, the operator (protector) can hold the handle 50 from the position on the rear leg side of the stroller 10 which is the rear side of the infant, so that the infant faces forward in the traveling direction. Push the stroller10. At this time, the front leg side of the stroller 10 becomes forward in the traveling direction. On the other hand, when the handle 50 is held at the second position, the operator can push the baby carriage 10 by holding the handle 50 from a position on the front leg side of the baby carriage 10 facing the infant. At this time, the rear leg side of the stroller 10 becomes forward in the traveling direction.

To change the position of the handle 50 between the first position and the second position, first, the holder 55 of the handle 50 is operated. When moving the handle 50 from the first position (rear pushing position) to the second position (facing pushing position), the holder 55 is lifted upward along the longitudinal direction of the shaft portion 51 a of the handle main body 51 . This operation is carried out by applying an external force against the urging force of the second urging member 54 to the holder 55 . When the holder 55 moves relative to the handle body 51 , the first position holding member 35 housed in the support portion 58 a of the holder 55 is exposed from the support portion 58 a. Thereby, the engagement between the handle 50 and the main body frame 12 is released, and the handle 50 can swing relative to the main body frame 12 .

When the handle 50 is brought to the vicinity of the second position, the second position holding member 36 comes into contact with the guide surface 57 a of the holding body 55 . When the second position holding member 36 comes into contact with the guide surface 57a, the holder 55 is pushed upward along the longitudinal direction of the shaft portion 51a. When the handle 50 reaches the second position, the second position holding member 36 is out of contact with the guide surface 57a, and the holder 55 can move downward along the longitudinal direction of the shaft portion 51a. As a result, the holder 55 is automatically moved downward by the urging force from the second urging member 54 , and the support portion 58 a of the holder 55 covers the second position holding member 36 . Accordingly, the relative swing between the handle 50 and the main body frame 12 is restricted, and the handle 50 is held at the second position.

It should be noted that the pushing operation of the holder 55 is carried out against the urging force of the second urging member 54 by the contact between the second position holding member 36 and the guide surface 57 a. The operator (protector) can sense that the handle 50 is approaching the second position which is the target position by sensing that the second position holding member 36 pushes the holding body 55 . Therefore, the operator can gradually decelerate and end the swing of the handle 50 . Therefore, the swing position of the handle 50 can be changed without giving a large impact to the main body frame 12 .

When the handle 50 is swung from the second position to the first position, almost the same operation as when the handle 50 is swung from the above-mentioned first position to the second position is performed. That is, it is only necessary to first pull up the holder 55 of the handle 50 and then move the handle 50 from the second position to the first position.

However, when the handle 50 is swung between the first position and the second position, the operation member 60 is also rotated with the handle main body 51 about the swing axis sa relative to the main body frame 12 . Therefore, the first contact surface 62a, the convex surface 62c, and the second contact surface 62b reach the surface of the support plate 48 of the state maintaining member 45 along the length direction of the main link member 21 in this order or in the reverse order of this order. right location. Moreover, the convex surface 62c separated from the swing axis sa compared with the first contact surface 62a and the second contact surface 62b is in contact with the support plate 48 at a position facing the support plate 48 along the length direction of the main link member 21. contact and press the support plate 48 upward. Here, the state maintaining member 45 including the support plate 48 is biased downward by the first biasing member 49 . Therefore, when the operator swings the handle between the first position and the second position, the operator can grasp that the swing operation is performed smoothly by sensing that the operation member 60 pushes the state maintaining member 45 . In addition, the handle 50 located at the intermediate position between the first position and the second position can be guided to the first position or the second position by the biasing force from the first biasing member 49 . It should be noted that the amount of movement of the state maintaining member 45 accompanying the swing of the handle 50 is so slight that the restricting engagement protrusion 47 does not come out of the engaging restricting recess 33 of the third link 30 . In other words, the state maintaining member 45 does not reach the release position due to movement accompanying the swing of the handle 50 .

Next, the operation when folding the stroller 10 having the above configuration from the unfolded state will be described. The above-mentioned main body frame 12 can be folded by relatively rotating each constituent member. Specifically, the third link 30 is rotated clockwise in FIG. 2 relative to the rear leg 16 by temporarily pulling the first link 20 upward and rearward using the handle 50 and then lowering it down. Accompanying this operation, the armrest 19 and the second link 25 rotate clockwise in FIG. 2 relative to the first link 20 . By such an operation, the first link 20 is arranged substantially parallel to the front leg 14 in a side view, and the position of the handle 50 with respect to the swing axis sa of the main body frame 12 is lowered. As above, the stroller 10 can be folded.

In particular, in the illustrated example, the handle 50 is connected to the main body frame 12 at the lower end portion of the handle main body 51 on the one hand, and is connected to the main body frame 12 via the holder 55 on the other hand. Furthermore, the holder 55 is supported by the handle main body 51 so as to be movable relative to the handle main body 51 . Therefore, as shown in FIGS. 3 and 4 , the main body frame 12 can be folded even when the handle 50 is held at any one of the first position and the second position. In addition, when the handle 50 is held at any one of the first position and the second position, the swing axis sa of the handle 50 relative to the main body frame 12 is positioned further in the folded state of the main body frame 12 than in the unfolded state. position below. That is, both the stroller main body 11 including the handle 50 and the stroller 10 can be downsized in the folded state compared to the unfolded state.

It should be noted that the lower end portion of the handle main body 51, which is one connection position of the handle 50 with respect to the main body frame 12, is connected to the main body frame 12 at the connection position of the first link 20 and the second link 25 by using the shaft member 34. . With the handle 50 held at the first position, the holding body 55 is connected to the main body frame 12 by engaging with the first position holding member 35 . Furthermore, the first position maintaining member 35 is fixed to the first link 20 . That is, in a state where the handle 50 is held at the first position, the handle 50 is connected to the first link 20 at two positions. When the folding operation of the stroller 10 starts while the handle 50 is held at the first position, the handle 50 cannot move relative to the first link 20 . Therefore, when the folding operation starts while the holding body 55 is engaged with the first position holding member 35 , the holding body 55 cannot move relative to the handle main body 51 . During the folding operation of the stroller 10 , the second urging member 54 continues to act on the holding body 55 to maintain the engaged state between the holding body 55 and the first position holding member 35 .

On the other hand, in a state where the handle 50 is held at the second position, the holding body 55 is connected to the main body frame 12 by engaging with the second position holding member 36 . Furthermore, the second position holding member 36 is not fixed to either the first link 20 or the second link 25 , but is fixed to the armrest 19 . That is, in a state where the handle 50 is held at the second position, the handle 50 is connected to various components that relatively act upon the folding action of the main body frame 12 . Specifically, in the state where the handle 50 is held at the second position, the handle 50 is connected to the connection positions of the first link 20 and the second link 25 on the one hand, and connected to the armrest 19 on the other hand. Also, as can be understood from a comparison of FIGS. 2 and 4 , by folding the main body frame 12 , the two connection positions of the handle 50 and the main body frame 12 are separated from each other. Therefore, when the folding operation starts in a state where the holding body 55 is engaged with the second position holding member 36 , the holding body 55 moves relative to the handle main body 51 . More specifically, the holder 55 moves along the shaft portion 51 a of the handle body 51 to the side separated from the swing axis sa, that is, to the upper side. The holding body 55 moves relative to the handle body 51 against the urging force from the second urging member 54 . Therefore, in this folding operation, the second urging member 54 urges the holder 55 toward the second position holding member 36 . That is, the second urging member 54 continues to act on the holder 55 during the folding operation to maintain the engaged state between the holder 55 and the second position holding member 36 .

However, before the folding operation of the stroller 10, it is necessary to move the state maintaining member 45 from the restricting position to the non-restricting position. As described above, regardless of which of the first position and the second position the handle 50 is located, the operation member 60 provided on the handle 50 can press the state maintaining member 45 by moving relative to the handle main body 51 to move it from the restricted position. Move to the release position.

To describe specifically, first, when the handle 50 is located at the first position, as shown in FIG. The support plate 48 of 45 faces. Moreover, as shown in FIG. 12 , if the operating member 60 moves upward along the shaft portion 51 a, the state maintaining member 45 is pressed by the first contact surface 62 a of the operating member 60 to move upward along the longitudinal direction of the main link member 21 . move. As a result, when the operating member 60 moves from the non-operating position shown in FIG. 11 to the operating position shown in FIG. 12 , the state maintaining member 45 moves from the restricting position shown in FIG. 11 to the releasing position shown in FIG. 12 . When the handle 50 is at the second position, as shown in FIG. right. Moreover, as shown in FIG. 14 , if the operating member 60 moves upward along the shaft portion 51 a, the state maintaining member 45 is pressed by the second contact surface 62 b of the operating member 60 to move upward along the longitudinal direction of the main link member 21 . move. As a result, when the operating member 60 moves from the non-operating position shown in FIG. 13 to the operating position shown in FIG. 14 , the state maintaining member 45 moves from the restricting position shown in FIG. 13 to the releasing position shown in FIG. 14 . That is, regardless of which of the first position and the second position the handle 50 is located, by operating the remote operation device 52 in the same manner, the operation member 60 can be operated to move the state maintaining member 45 from the restriction position to the release position.

As described above, in the present embodiment, the stroller 10 has the main body frame 12 deformable from the unfolded state to the folded state, and the main body frame 12 is swingably connected between the first position and the second position. Handle 50. The main body frame 12 has a state maintaining member 45 movable between a restriction position where the folding operation of the baby carriage 10 is restricted and a release position where the folding operation of the baby carriage 10 is enabled. The handle 50 has a handle body 51 connected to the main body frame 12 , and an operation member 60 movably supported by the handle body 51 . The operating member 60 presses the state maintaining member 45 by moving the handle body 51 relative to the handle 50 at the first position to move from the restricting position to the release position, and passes through the handle body 51 relative to the handle 50 at the second position. The main body 51 operates to press the state maintaining member 45 and move it from the restriction position to the release position. According to this embodiment, when the handle 50 is located at any one of the first position and the second position, the operation member 60 can be engaged with the state maintaining member 45, and the state maintaining member 45 can be moved from the restriction position to the release position. move. Therefore, regardless of which of the first position and the second position the handle 50 is located, the folding operation can be started by operating the operation member 60 . For example, when infants are relatively young, there are many cases where the handle 50 is disposed on the side facing the infant and the stroller 10 is used. Folding is performed without changing the position. In addition, when the folded stroller 10 is unfolded, the handle 50 is arranged at the second position without change. Therefore, the step of adjusting the position of the handle 50 can be omitted, and the convenience of the stroller 10 can be improved.

In addition, in the present embodiment, the operation member 60 is movable between the operation position and the non-operation position, and is biased toward the non-operation position from the operation position side. The state maintaining member 45 is pressed by the operating member 60 that moves from the non-operating position to the operating position, and moves from the restriction position to the release position. In the illustrated example, the operation member 60 is biased toward the downward non-operation position, and presses the state maintaining member 45 from below. Accordingly, when the handle 50 is disposed at the first position and the second position, the state maintaining member 45 is operated by the operating member 60 that is operated toward the operating position against the urging force. Therefore, undesired operation of the state maintaining member 45 can be effectively prevented. Thereby, the baby carriage 10 can be stably maintained in the unfolded state.

Furthermore, in the present embodiment, the operation member 60 located at the non-operation position is separated from the state maintaining member 45 . Therefore, when the stroller 10 is unfolded from the folded state with the handle 50 disposed at the first position or the second position, a gap is formed between the state maintaining member 45 and the operating member 60 . Therefore, it is possible to effectively prevent clothing and the like from being caught between the state maintaining member 45 and the operating member 60 when the stroller 10 is unfolded.

Furthermore, in this embodiment, the operation member 60 is movable between an operation position and a non-operation position. The operating member 60 includes a first contact surface 62a capable of contacting the state maintaining member 45 when the handle 50 is located at the first position, and a second contact surface 62a capable of contacting the state maintaining member 45 when the handle 50 is located at the second position. Face 62b. According to such an operation member 60 , with a simple configuration, the engagement between the operation member 60 and the state maintaining member 45 can be ensured stably regardless of the swing position of the handle 50 .

Furthermore, in this embodiment, the operation member 60 has an operation base 61 slidable with respect to the handle 50 , and an operation protrusion 62 protruding in a direction intersecting the longitudinal direction of the portion of the handle 50 where the operation base 61 is provided. The operation protrusion 62 includes a first contact surface 62a and a second contact surface 62b. According to such an operation member 60 , with a simple configuration, the engagement between the operation member 60 and the state maintaining member 45 can be ensured stably regardless of the swing position of the handle 50 .

Furthermore, in the present embodiment, the operation member 60 is movable between the non-operation position and the operation position along the longitudinal direction of the portion of the handle main body 51 where the operation member 60 is provided. The second contact surface 62b includes an inclined surface inclined with respect to the moving direction of the operating member 60 from the non-operating position toward the operating position. The inclined surface is separated from the handle main body 51 from the front side toward the rear side in the moving direction of the operating member, which is the direction from the non-operating position toward the operating position. According to such an operation member 60 , with a simple configuration, the engagement between the operation member 60 and the state maintaining member 45 can be ensured stably when the handle 50 is located at both the first position and the second position.

Furthermore, in this embodiment, the operating member 60 further has a convex surface 62c located between the first contact surface 62a and the second contact surface 62b. The distance dx from the swing axis sa of the handle 50 with respect to the main body frame 12 to the convex surface 62c is longer than the distance dy from the swing axis sa to the portion 62a1 of the first contact surface 62a adjacent to the convex surface 62c and is smaller than the distance dx. The distance dz from the swing axis sa to the portion 62b1 of the second contact surface 62b adjacent to the convex surface 62c is long. According to this configuration, when the handle 50 swings from one of the first position and the second position to the other, the convex surface 62 c of the operation member 60 can come into contact with the state maintaining member 45 . In this case, the operator (protector) of the operating handle 50 can grasp that the operation is being performed smoothly by sensing the contact between the operating member 60 and the state maintaining member 45 . Also, when the state maintaining member 45 urges toward the operating member 60 , the handle 50 can be guided to either the first position or the second position by engaging the operating member 60 with the state maintaining member 45 .

Furthermore, in the present embodiment, the stroller 10 has a main body frame 12 deformable from an unfolded state to a folded state, and a handle 50 connected to the main body frame 12 so as to be able to swing between a first position and a second position. The handle 50 has a handle body 51 connected to the main body frame 12 , a holder 55 supported by the handle body 51 so as to be movable relative to the handle body 51 , and a second biasing member 54 for biasing the holder 55 . The main body frame 12 has a first position holding member 35 engaging with the holding body 55 to hold the handle 50 at the first position, and a second position holding member 36 engaging with the holding body 55 to hold the handle 50 at the second position. . In the state where the holding body 55 is engaged with the first position holding member 35, the main body frame 12 can be deformed to start the folding operation of the stroller 10, and in the state where the holding body 55 is engaged with the second position holding member 36, The folding operation of the stroller 10 can be started by deforming the main body frame 12 . The second biasing member 54 presses the holding body 55 toward the first position holding member 35 or the second position holding member 36 to act on the holding body 55 to maintain the holding body 55 and the first position holding member 35 or the second position holding member 36 engagement status. When the folding operation starts in the state where the holding body 55 is engaged with the second position holding member 36 , the holding body 55 is kept engaged with the second position holding member 36 by the urging force from the second biasing member 54 , And it moves relative to the handle main body 51 against the urging force from the second urging member 54 . That is, according to the present embodiment, the stroller 10 can be folded even when the handle 50 is located at any one of the first position and the second position. In particular, when the folding operation is started with the handle 50 disposed at the second position, the holding body 55 and the second position holding member 36 for holding the handle 50 at the second position relative to the main body frame 12 are positioned relative to the handle. The main body 51 moves. At this time, the holder 55 moves relative to the handle body 51 against the urging force from the second urging member 54 , and maintains engagement with the second position holding member 36 by the urging force from the second urging member 54 . Therefore, since the engagement between the handle 50 and the main body frame 12 is maintained, the operator (protector) can stably carry out the folding operation of the stroller 10 while holding the handle 50 . In addition, the second urging member 54 used to maintain the handle 50 at the first position and the second position can also be used to maintain the holding body 55 and the second position when the handle 50 is folded from the state maintained at the second position. An urging member for engagement of the two position holding members 36 . Therefore, a highly convenient stroller can be configured simply.

Furthermore, in the present embodiment, the handle 50 further includes a cover plate 53 provided on the handle main body 51 and forming a storage space rs for housing the second biasing member 54 therebetween. The cover plate 53 is formed with a groove 53a extending along the length direction of the handle body 51 and communicating with the storage space rs. The holder 55 has a protruding portion 56a protruding into the storage space rs via the groove 53a. According to such a structure, the baby carriage 10 with high convenience can be comprised simply. In addition, by replacing the holding body 55 with respect to the conventional stroller, and additionally providing the cover plate 53 and the second biasing member 54, it is possible to carry out the operation when the handle 50 is located at any one of the first position and the second position. Folding of the stroller 10 .

It should be noted that various changes can be made within the scope of the gist of the present invention regarding the above-mentioned one embodiment. Hereinafter, an example of modification will be described with reference to the drawings. In the following description and the drawings used in the following description, the same symbols as those used for the corresponding parts in the above-mentioned embodiment are used for parts that can be configured in the same way as in the above-mentioned embodiment, and overlapping descriptions are omitted. .

The holder 55 and the second urging member 54 described in the above-mentioned one embodiment are merely examples. For example, the second urging member 54 may have a structure other than a compression spring. As the second urging member 54, a tension spring may be used as shown in FIG. 17 . As shown in FIG. 18 , one end of the filamentary member 54 a may be attached to the protrusion 56 a of the holder 55 , and a device 54 b for winding the filamentary member 54 a may be provided on the handle 50 . In addition, in the above-mentioned one embodiment, the example in which the cover plate 53 is provided on the handle main body 51 and the storage space rs is formed between the handle main body 51 and the cover plate 53 was shown, but it is not limited to this. As shown in FIG. 17 , a partition member 153 may be provided inside the handle body 51 to form a storage space rs between the partition member 153 and the handle body 51 . Furthermore, as shown in FIG. 18, the internal space of the handle main body 51 may form the storage space rs. In addition, in the example shown in FIG. 17 and FIG. 18, the long groove 51d extended along the longitudinal direction of the handle main body 51 is formed in the handle main body 51. As shown in FIG. The engaging portion 58 of the holder 55 passes through the elongated groove 51d and protrudes into the storage space rs.

In addition, in the above-mentioned one embodiment, the example in which the first position maintaining member 35 is fixed to the main link member 21 of the first link 20 was shown, but it is not limited to this example. The upper connecting piece 22, the armrest 19, the rear leg 16 and the like fix the first position holding member 35. In addition, in the above-mentioned one embodiment, the example in which the second position holding member 36 is fixed to the armrest 19 was shown, but it is not limited to this example, for example, the second position may be fixed to the front leg 14 and/or the rear leg 16. Holding part 36. Furthermore, the distance from the swing axis sa of the handle 50 with respect to the main body frame 12 to the first position holding member 35 and the distance from the swing axis sa to the second position holding member 36 may be different. When the distance from the swing axis sa to the first position holding member 35 is different from the distance from the swing axis sa to the second position holding member 36, the holding body 55 in the case where the handle 50 is located at the first position is positioned on the handle. The position on the main body 51 is different from the position of the holder 55 on the handle main body 51 when the handle 50 is in the second position.

Furthermore, in one embodiment described above, the example in which the first position holding member 35 and the second position holding member 36 cannot move relative to the holding body 55 while being engaged with the holding body 55 was shown. However, as in the examples shown in FIGS. 19 to 28 , the position holding members 35 and 36 may be relatively movable relative to the holding body 55 along the longitudinal direction of the handle main body 51 on the portion where the holding body is provided. The way is engaged with the holder.

19 to 21 show a holding body 255, FIGS. 22 and 23 show a stroller 10, and FIGS. Action of holder 255 is shown. 26 and 27 show the stroller 10, and FIG. 28 shows the operation of the holder 355 as a second example in which the holder and the second position holding member 36 are relatively movably engaged. The holder 255 of the first example shown in FIGS. 19 to 25 and the holder 355 of the second example shown in FIGS. The longitudinal direction of the portion provided with the holders 255 , 355 moves relative to the handle main body 51 . The holders 255 , 355 move relative to the handle body 51 , and in the illustrated example, move downward on the handle body 51 to engage with the first position holding member 35 and the second position holding member 36 . On the other hand, the holder 255 of the first example shown in FIGS. 19 to 25 and the holder 355 of the second example shown in FIGS. 26 to 28 are different from the holder 55 in the above-mentioned one embodiment. The longitudinal direction of the shaft portion 51a of the handle main body 51 becomes longer. First, such holders 255 and 355 have an advantage of being easy to handle because they are located near the operator's (protector's) hand. In addition, there is an advantage of stabilizing the relative movement of the holders 255 , 355 with respect to the handle main body 51 along the longitudinal direction of the shaft portion 51 a of the handle 50 . Hereinafter, the first example and the second example will be described focusing on differences from the above-described one embodiment.

First, in the first example, the holding body 255 has the cylindrical main body portion 56 held by the shaft portion 51 a and an engaging position capable of engaging with the position holding members 35 and 36 similarly to the holding body 55 in the above-mentioned one embodiment. part 58 , and guide parts 57 arranged on both sides of the engaging part 58 . Among them, the guide portion 57 is configured in the same manner as in the above-mentioned one embodiment.

On the other hand, the cylindrical main body part 56 is longer than the one embodiment mentioned above. As shown in FIGS. 24 and 25 , on the inner surface of the cylindrical main body portion 56 , an accommodation groove portion 56 c that is a space extending along the longitudinal direction of the shaft portion 51 a is formed. The upper end of the storage groove part 56c is open, but the lower end of the storage groove part 56c is closed by the support bottom part 56d. In addition, a holding protrusion 51 e protruding radially outward is provided on the shaft portion 51 a of the handle 50 to which the cylindrical main body portion 56 is attached. The protrusion amount of the holding protrusion 51e from the shaft portion 51a is smaller than the depth of the accommodation groove portion 56c. Since the holding protrusion 51 e is located in the storage groove 56 c, the holding protrusion 51 e does not hinder the movement of the holding body 255 on the handle main body 51 . The second urging member 54 is accommodated in the accommodation groove portion 56c. In other words, the storage groove portion 56c forms the storage space rs of the second urging member 54 . The second urging member 54 is arranged between the holding protrusion 51e and the support bottom portion 56d. The second urging member 54 is composed of, for example, a compression spring, and urges the holder 255 toward the position holding members 35 , 36 . In addition, the cylindrical main body portion 56 is provided with a flange portion 56b having an enlarged diameter at the upper end of the outer surface thereof. An operator (protector) can hold the flange portion 56b and operate the holder 255 .

Next, as shown in FIGS. 23 to 25 , the engaging portion 58 extends along the longitudinal direction of the handle main body 51 at the portion where the holder 255 is provided. The engaging portion 58 can engage with the first position holding member 35 and the second position holding member 36 . In the state where the second position holding member 36 is engaged with the engaging portion 58 of the holding body 255 , it can move relative to the engaging portion 58 along the longitudinal direction of the engaging portion 58 , that is, along the longitudinal direction of the shaft portion 51 a of the handle main body 51 . The joint portion 58 moves relatively. Specifically, as shown in FIG. 20 , the engaging portion 58 of the holder 255 is formed as a groove 58 b extending along the longitudinal direction of the engaging portion 58 , that is, along the longitudinal direction of the shaft portion 51 a of the handle body 51 . As shown in FIGS. 20 and 21 , the groove 58 b opens forward in the moving direction at an end portion on the front side in the moving direction of the holder 255 when engaged with the second position holding member 36 . That is, the groove 58b opens toward the position holding members 35 and 36 when the handle 50 is located at the first position or the second position. In the illustrated example, the groove 58b opens downward. Therefore, the holding body 255 moves downward on the handle main body 51 to approach the position holding members 35 , 36 , and the engaging portion 58 of the holding body 255 accommodates the position holding members 35 , 36 . At this time, the relative movement of the position holding members 35 and 36 relative to the groove 58b in a direction non-parallel to the longitudinal direction of the groove 58b is restricted by engaging with the groove 58b. On the other hand, the groove 58b has a constant cross-sectional shape at each position along its length direction. Therefore, the position holding members 35 and 36 can move within the groove 58b along the longitudinal direction of the groove 58b. That is, the position holding members 35 and 36 are allowed to move relative to each other along the longitudinal direction of the groove 58 b in a state where the swinging of the handle 50 is restricted by engaging with the holding body 255 .

It should be noted that the position holding members 35 and 36 have diameter-enlarged portions at the front ends that can be positioned in the groove 58b. On the other hand, the engaging portion 58 of the holder 255, 355 has a restricting flange 58c that restricts the enlarged diameter portion from being pulled out of the groove 58b. Therefore, in the illustrated example, the position holding members 35 and 36 can enter the groove 58b only from the opening 58ba. Moreover, in the state where the position holding members 35, 36 are located in the groove 58b, the position holding members 35, 36 can be moved only along the longitudinal direction of the holding bodies 255, 355 (the longitudinal direction of the shaft portion 51a) with respect to the holding bodies 255, 355. Relative movement, in other words, relative movement in a direction non-parallel to the longitudinal direction of the holders 255, 355 (the longitudinal direction of the shaft portion 51a) is restricted.

Also in the stroller 10 shown in FIGS. 23 and 24 , the main body frame 12 can be deformed to start the folding operation in a state where the holder 255 is engaged with the first position holding member 35 . As already described above, in a state where the handle 50 is held at the first position, the position of the main body frame 12 on the swing axis sa of the handle 50 and the two positions of the first position holding member 35 are connected to the handle 50 . Furthermore, the first position holding member 35 is fixed to the first link 20 defining the swing axis sa. Therefore, even if the main body frame 12 is deformed during the folding operation, the distance from the swing axis sa to the first position holding member 35 does not change. That is, when the folding operation starts while the holding body 255 is engaged with the first position holding member 35 , the first position holding member 35 does not move relative to the holding body 255 on the handle main body 51 . In addition, the holding body 255 does not move relative to the handle main body 51 due to the urging force from the second urging member 54 during the folding operation.

On the other hand, in a state where the handle 50 is held at the second position, the holding body 55 is connected to the main body frame 12 by engaging with the second position holding member 36 . Furthermore, the second position holding member 36 is not fixed to either the first link 20 or the second link 25 , but is fixed to the armrest 19 . As can be seen from a comparison of FIG. 22 and FIG. 23 , during the folding operation, the distance from the swing axis sa to the second position holding member 36 gradually becomes longer along with the deformation of the main body frame 12 during the folding operation. Therefore, when the folding operation is started in a state where the holding body 255 is engaged with the second position holding member 36 , the second position holding member 36 follows the opening of the handle main body 51 on the portion where the holding body 255 is provided during the folding operation. The longitudinal direction moves relative to the holder 255 . At this time, the holding body 255 does not move relative to the handle main body 51 due to the biasing force from the second urging member 54 . The second position holding member 36 moves relative to the holding body 255 in a direction away from the swing axis sa along the handle main body 51 . Specifically, as shown in FIG. 24 , in the groove 58 b of the holder 255 , it moves from the side of the opening 58 ba located below to the innermost portion 58 bb located above.

In the illustrated example, the second position holding member 36 reaches the innermost portion 58bb in the groove 58b as shown by the dashed-two dotted line in FIG. . At this time, as shown in FIG. 25 , the second position holding member 36 moves relative to the handle main body 51 together with the holding body 255 . At this time, the movement of the holder 255 relative to the handle body 51 is performed against the urging force from the second urging member 54 . Therefore, in this folding operation, the second urging member 54 urges the holder 255 toward the second position holding member 36 . That is, the second urging member 54 continues to act on the holding body 255 during the folding operation to maintain the engaged state between the holding body 255 and the second position holding member 36 . It should be noted that the relative movement direction of the second position holding member 36 with respect to the holding body 255 is along the direction of the relative movement of the holding body 255 with respect to the handle main body 51 . Therefore, it is possible to smoothly switch from an operation in which the second position holding member 36 moves relative to the holding body 255 to an operation in which the second position holding member 36 and the holding body 255 move relative to the handle body 51 .

Next, a second example in which the second position holding member 36 engages with the holder so as to be relatively movable will be described with reference to FIGS. 26 to 28 . The second example shown in FIG. 26 and FIG. 28 is different in that the length of the holder 355 and the length of the engaging portion 58 are longer than the first example shown in FIGS. 19 to 25 , and the same configuration can be adopted otherwise.

In the examples shown in FIGS. 26 to 28 , the folding operation of the stroller starts in a state where the retainer is engaged with the second position holding member, and the second position holding member 36 At first, when the innermost portion 58bb is reached in the groove 58b, or the baby carriage is folded in a state in which the above-mentioned holding body is engaged with the above-mentioned second position holding member, even if the main body frame 12 is deformed into the folded state, the second position holding member 36 It does not reach the innermost part 58bb in the groove 58b either. Therefore, when the folding operation of the baby carriage 10 is started in a state where the holder 355 is engaged with the first position holding member 35 , and when the folding operation of the baby carriage 10 is started in a state where the holder 355 is engaged with the second position holding member 36 In either case of the folding operation, the holding body 355 is not pressed by the position holding members 35 , 36 , so the holding body 355 does not move relative to the handle body 51 by the urging force from the second urging member 54 .

In the example described with reference to FIGS. 19 to 28 , the stroller 10 that can be folded from the unfolded state to the folded state has a main body frame 12 that can be deformed from the unfolded state to the folded state, and a baby carriage that can be positioned between the first position and the second position. The handle 50 is connected to the main body frame 12 in a swingable manner. The handle 50 has a handle main body 51 connected to the main body frame 12 , and holders 255 , 355 supported by the handle main body 51 so as to be movable relative to the handle main body 51 . The main body frame 12 has a first position holding member 35 that engages with the holders 255, 355 to restrict the swing of the handle 50 from the first position, and a first position holding member 35 that engages with the holders 255, 355 to restrict the swing of the handle 50 from the second position. The second position holding member 36 . Further, the second position holding member 36 engages with the holders 255 , 355 so as to be relatively movable relative to the holders 255 , 355 along the longitudinal direction of the handle body 51 at the portion where the holders 255 , 355 are provided. On the other hand, between the unfolded state and the folded state, the main body frame 12 deforms, and the relative positions of the main body frame 12 and the handle 50 change. At this time, the holders 255 , 355 and the second position holding member 36 , which are the engagement positions between the main body frame 12 and the handle 50 , can move relatively, corresponding to the deformation of the main body frame 12 during the unfolding or folding operation. Therefore, even when the distance from the second position holding member 36 to the swing axis sa of the handle 50 changes between the unfolded state and the folded state, it is possible to pass the distance between the holding bodies 255, 355 and the second position holding member 36. The engagement restricts the free swing of the handle 50 relative to the main body frame 12, and the stroller 10 is folded. In other words, regardless of which of the first position and the second position the handle 50 is located, the folding operation can be started. For example, when infants are young, the handle 5 is often disposed on the side facing the infant and the stroller 10 is used. Folding is performed without changing the position. In addition, when the folded stroller 10 is unfolded, the handle 50 is arranged at the second position without change. Therefore, the step of adjusting the position of the handle 50 can be omitted, and the convenience of the stroller 10 can be improved. In addition, the restriction on the installation position of the second position holding member 36 is reduced, the degree of freedom in the design of the stroller 10 is increased, and the size and weight of the stroller 10 can also be reduced. Furthermore, the engagement between the holders 255 and 355 and the second position holding member 36 can be further engaged during the folding operation. Therefore, even during the folding operation, the state in which the holders 255 , 355 are engaged with the second position holding member 36 can be stably maintained.

In addition, in the examples shown in FIGS. 19 to 28 , when the holding bodies 255 and 355 start the folding operation in a state engaged with the second position holding member 36 , the second position holding member 36 is in the folding operation. It moves relative to the holding bodies 255 , 355 along the length direction of the handle main body 51 at the portion where the holding bodies 255 , 355 are provided. Therefore, even when the distance from the second position holding member 36 to the swing axis sa of the handle 50 changes between the unfolded state and the folded state, the holders 255 , 355 that become the engagement positions of the main body frame 12 and the handle 50 And the second position holding member 36 can follow the deformation of the main body frame 12 during the unfolding operation or the folding operation, and relatively move more smoothly. As a result, when the folding operation of the stroller 10 is started in a state where the holders 255 and 355 are engaged with the second position holding member 36 , stable and smooth folding can be performed.

Furthermore, in the example shown in FIGS. 19 to 28 , during the relative movement of the second position holding member 36 with respect to the holding bodies 255 , 355 , the holding bodies 255 , 355 are provided with the holding bodies 255 , 355 on the handle main body 51 . The lengthwise direction on the portion is at a fixed position, in other words, the holding body 255, 355 does not move on the handle body 51 along the lengthwise direction of the handle body 51 on the portion where the holding body 255, 355 is provided. Therefore, the relative movement of the holding bodies 255, 355 and the second position holding member 36 can be realized stably and smoothly. As a result, when the folding operation of the stroller 10 is started in a state where the holders 255 and 355 are engaged with the second position holding member 36 , stable and smooth folding can be performed.

In addition, in the examples shown in FIGS. 19 to 25 , when the folding operation is started in a state where the holder 255 is engaged with the second position holding member 36 , the second position holding member 36 is provided along the handle main body 51 . The portion with the holder 255 moves relative to the holder 255 in the longitudinal direction, and then the second position holding member 36 stops moving relative to the holder 255 and moves with the holder 255 relative to the handle body 51 . According to such an example, the length of the holding body 255 can be shortened, and at the same time, the amount of movement of the holding body 255 relative to the handle main body 51 can be reduced. Thus, when the folding operation of the stroller 10 is started in a state where the holder 255 is engaged with the second position holding member 36 , stable and smooth folding can be performed, and the size and weight of the stroller 10 can be reduced.

In particular, in the examples shown in FIGS. 19 to 25 , the direction of relative movement of the second position holding member 36 with respect to the holder 255 is along the direction of the relative movement of the holder 255 with respect to the handle body 51 . Therefore, the length of the holding body 255 can be shortened more effectively, and at the same time, the amount of movement of the holding body 255 relative to the handle main body 51 can be reduced. Thus, when the folding operation of the stroller 10 is started in a state where the holder 255 is engaged with the second position holding member 36 , stable and smooth folding can be performed, and the size and weight of the stroller 10 can be reduced.

According to the example shown in FIGS. 26 to 28 , when the folding operation is started in a state where the holding body 355 is engaged with the second position holding member 36 , the holding body 355 is held on the handle during the period from the unfolded state to the folded state. The length direction of the main body 51 on the portion where the holder 355 is provided is at a fixed position, in other words, does not move on the handle body 51 along the length direction of the handle body 51 on the portion where the holder 355 is provided. On the other hand, when the folding operation is started in a state where the holding body 355 is engaged with the second position holding member 36 , the second position holding member 36 continues to hold relative to the holding body 355 from the unfolded state to the folded state. relative movement. That is, according to such an example, during the folding operation, only the second position holding member 36 moves relative to the holding body 355 , and the holding body 355 can be kept in a stationary state relative to the handle main body 51 . Therefore, when the folding operation of the stroller 10 is started in a state where the holder 355 is engaged with the second position holding member 36 , stable and smooth folding can be performed. In addition, the amount of movement of the holding body 355 relative to the handle main body 51 may be an amount necessary only for the engagement and disengagement of the first position holding member 35 and the second position holding member 36 . Thereby, reduction in size and weight of the stroller 10 can be effectively achieved.

It should be noted that some modification examples to the above-mentioned embodiment have been described above, and of course a plurality of modification examples can be applied in combination as appropriate.
