The second link 22 is rotatably connected to the seat support body 40 and the first link 21 . In the example shown in the figure, the second link 22 is connected to the seat support body 40 at an intermediate portion in the front-rear direction. The second link 22 is rotatable relative to the seat support body 40 about the fourth rotation axis RA4 extending in the width direction. Further, the second link 22 is connected to the front-rear connection portion 53 of the central link member 50 constituting the first link 21 in the middle portion in the front-rear direction. The second link 22 is rotatable relative to the first link 21 about the fifth rotation axis RA5 extending in the width direction. The pair of second links 22 are provided so as to be spaced apart in the width direction. Each second link 22 is connected to the side portion 41a of the seat support body 40 on the same side in the width direction, and is connected to the first link 21 (front-rear connection portion 53 ) on the same side in the width direction.

In the example shown in the figure, the second link 22 is constituted by a support frame member 55 . The support frame 55 is configured as a metal rod-shaped member. As shown in FIG. 1 , the support frame 55 extends in the width direction at the upper end and the lower end. The support frame 55 extends in the up-down direction between the upper end portion and the lower end portion. Each support frame member 55 is bent toward the outer side in the width direction in the upper end portion thereof, and penetrates the seat mounting member 44 located on the same side in the width direction. The fourth rotation axis RA4 coincides with the center axis of the upper end portion of the rod-shaped support frame 55 . Each support frame member 55 is bent toward the inner side in the width direction in the lower end portion thereof, and penetrates the front and rear connecting portions 53 located on the same side in the width direction. The fifth rotation axis RA5 coincides with the center axis of the lower end portion of the rod-shaped support frame 55 . According to such an attachment structure of the support frame 55, when a force in the width direction is applied to the seat support body 40, the support frame can be effectively prevented from being supported. 55 is detached from the first link 21 or the seat support body 40 , and as a result, the seat support body 40 can be stably supported by the support frame 55 .

In addition, the inner side (inside) in the width direction refers to the side close to the center of the stroller 10 in the width direction. The outer side (outside) in the width direction refers to the side away from the center of the stroller 10 in the width direction.

The support frame member 55 extends in a substantially vertical direction in the side view state shown in FIG. 4 . Typically, the angle formed by the support frame member 55 with respect to the vertical direction in a side view is preferably 10° or less, more preferably 5° or less, and further preferably 0°. According to such a support frame 55, the front portion of the seat support body 40 whose rear end portion is connected to the handle 30 can be stably supported from below.

Moreover, as shown in FIG. 1, each support frame 55 is inclined with respect to the up-down direction so that it may go inward in the width direction from the top down. As a result, the spaced interval in the width direction of the pair of support frame pieces 55 is gradually narrowed from top to bottom in the up-down direction. According to such a support frame 55, even when a force in the width direction is applied to the seat support body 40, the seat support body 40 can be stably supported.

The third link 23 is rotatably connected to the middle portion of the grip 30 in the vertical direction. In addition, the third link 23 is rotatably connected to the rear leg 62 .

The folded-back portion 62b2 is connected to the third link 23 (connecting link member 65) at the upper end portion. In addition, each front leg 60 is rotatably connected to the folded-back portion 62b2 of the rear leg 62 on the same side in the width direction.

As shown in FIG. 2 , a rear connecting member 64 is provided between the pair of rear legs 62 . The rear connecting member 64 extends in the width direction and connects the pair of rear legs 62 .

In addition, the stroller body 20 further includes a standing member 70 extending between the front legs 60 and the rear legs 62 in the front-rear direction. The standing member 70 is rotatably connected to the member protruding laterally from the front leg 60 and the rear connecting member 64, and can be bent. In the illustrated example, the standing member 70 is rotatably connected to the front connecting portion 52 and the rear connecting member 64 of the center link member 50 connected between the pair of front legs 60 . The standing member 70 is bent so as to protrude toward the side away from the seat support body 40 as shown in FIG. And, through By grounding the bent standing member 70 to the pair of rear wheels 63, as shown in FIGS. 5 and 6, the folded stroller 10 (the stroller body 20) can be erected.

As shown in FIG. 4 , the standing member 70 includes a first standing element 71 rotatably connected to the front connecting portion 52 of the center link member 50 , and a second standing element 72 rotatably connected to the rear connecting member 64 . The first standing element 71 and the second standing element 72 are rotatably connected to each other about the ninth rotation axis RA9 extending in the width direction. In particular, the first standing element 71 is connected to the front connecting portion 52 at the front end portion thereof, and is connected to the second standing element 72 at the rear end portion thereof. The second standing element 72 is connected to the first standing element 71 at the front end portion thereof, and is connected to the rear connecting member 64 at the rear end portion thereof.

As shown in FIGS. 5 and 6 , when the stroller 10 (the stroller body 20 ) is folded, the first standing element 71 extends along the front legs 60 in a side view. As shown in FIG. 4 , in a side view of the stroller 10 in the unfolded state, from the center of rotation of the first standing element with respect to the member (front connecting portion 52 ) protruding laterally from the front leg 60 to the first standing The length LX to the end of the element 71 is longer than the longest distance LY from the rotation center to the outer periphery of the wheel (front wheel 61 ) held by the front leg 60 . Therefore, when the stroller 10 (the stroller main body 20 ) is folded, the first standing element 71 protrudes further than the front wheel 61 in a side view.

The 1st standing element 71 shown in FIG. 4 has the 1st rod 71a connected to the front connection part 52, and the end member 71b attached to the rear-end part of the 1st rod 71a. The end member 71b covers the rear end of the first rod 71a. The end member 71b has an end portion 71ba located at the rear end and a protruding portion 71bb located in front of the end portion 71ba and protruding upward. The end piece 71b is connected to the second standing element 72 in its protruding portion 71bb. As shown in FIGS. 5 and 6 , when the standing member 70 is bent, the end portion 71ba protrudes and is grounded. For example, the first rod 71a is formed of a metal tubular member, and the end member 71b is formed of a resin molding.

In addition, not limited to the illustrated example, the standing member 70 and the first standing element 71 may be rotatably connected to the front leg 60 instead of the front connecting portion 52 .

Next, the storage case 12 and the seat member 15 attached to the stroller main body 20 having the above-described configuration will be described. The storage box 12 and the seat member 15 are deformed together with the stroller body 20 when the stroller 10 is folded. Therefore, the storage case 12 and the seat member 15 are made of, for example, a material having flexibility such as cloth, and are configured to be deformable along with the stroller body 20 .

In the example shown in FIG. 3 , the storage box 12 is attached to the front-rear connection portion 53 and the rear legs 62 of the center link member 50 . Further, the storage box 12 is supported from below by the stand member 70 . By being supported by the stand member 70, the shape of the storage box 12 having a deformable structure can be stabilized. Thereby, the volume of the storage box 12 can be increased, and the storage force can be improved.

Next, the seat member 15 will be described. As shown in FIG. 3 , the seat member 15 has a seat portion 15A supported by the seat support body 40 and a back portion 15B connected to the seat portion 15A. The seat portion 15A faces the buttocks of the infant riding on the stroller 10 from below. The back 15B faces the back of the infant riding on the stroller 10 from the rear. In the illustrated example, the lower end portion of the back portion 15B is connected to the rear end portion of the seat portion 15A. The back portion 15B is swingable relative to the seat portion 15A. The reclining operation of the seat member 15 can be performed by swinging the back portion 15B with respect to the seat portion 15A. The seat member 15 further has the adjustment member 18 attached to the shaft portion 31a of the grip 30 through the rear of the back portion 15B. The adjustment member 18 is a rope-like member. By adjusting the length of the adjustment member 18, the inclination angle of the back part 15B with respect to the seat part 15A, that is, the reclining angle can be adjusted.

Moreover, as shown in FIG. 3, the seat member 15 includes the side member 16 which faces the infant from the side. The pair of side pieces 16 are provided on both sides in the width direction of the seat portion 15A and the back portion 15B. 16 side pieces Connected to the seat portion 15A and the back portion 15B, for example, sewed to the seat portion 15A and the back portion 15B. The pair of side members 16 are expected to protect the infant riding on the stroller 10 from both sides, and are also expected to hold the infant from both sides.

Each side piece 16 is attached to the seat support body 40 and the handle 30 . In the illustrated example, each side member 16 is fixed to the side portion 41a of the seat frame 41 located on the same side in the width direction and the shaft portion 31a of the grip body 31 located on the same side in the width direction through the fixing mechanism 16a . The bendable position of the handle 30 (the position of the bending axis BA) is located between the position where the seat support 40 is connected to the handle 30 and the position where the side piece 16 is connected to the handle 30 . In the example shown in particular, the side piece 16 can be maintained between the side portion 41 a of the seat frame 41 and the shaft portion 31 a of the grip body 31 in a tensioned state. Such a side member 16 functions as a connection reinforcement mechanism 17 which is located in front of the position of the seat support body 40 connected to the handle 30 (the position of the first rotation axis RA1 ) and the handle 30 The front part of the seat support 40 connected to the handle 30 at the rear end is hoisted upward between the positions above the position connected to the seat support 40 (the position of the first rotation axis RA1). The seat support body 40 can be stably supported by the side member 16 functioning as the connection reinforcement mechanism 17 .

Furthermore, the side member 16 shown in FIG. 3 contains the reinforcement member 16b in the position between the position fixed to the seat support body 40, and the position fixed to the grip 30. The reinforcement member 16b reinforces the rigidity of the side member 16 locally. That is, the rigidity of the side member 16 at the position where the reinforcement member 16b is provided is higher than the rigidity of the side member 16 at the position where the reinforcement member 16b is not provided. Therefore, by providing the side member 16, the front part of the seat support body 40 can be hoisted upward more stably. The reinforcing member 16b shown in the drawing is composed of a wire or a tape, and is arranged along the straight line connecting the position where the side member 16 is fixed to the seat support body 40 and the position where the side member 16 is fixed to the grip 30. superior. Therefore, the side member 16 can be effectively reinforced and the seat support body 40 can be stably supported.

The stroller 10 having the above-described configuration can be folded by relatively rotating the respective components of the stroller body 20 . Specifically, the stroller 10 can be folded by operating the stroller 10 by gripping the handle 30 as described below. By folding the stroller 10, the size of the stroller 10 can be reduced to a size suitable for storage, transportation, or the like.

First, the grip 30 is temporarily lifted back upward. Then, by lowering the handle 30 downward, the fourth link 24 constituted by the bracket member 67 is rotated in the clockwise direction in FIG. 4 with respect to the rear leg 62 . In accordance with this operation, the first link 21 and the third link 23 are rotated in the clockwise direction in FIG. 4 with respect to the grip 30 . As a result, the grip 30 and the front legs 60 approach each other while maintaining a substantially parallel arrangement in the side view, and the position of the grip 30 is lowered.

Moreover, the seat support body 40 which is rotatably connected to the grip 30 is connected to the first link 21 via the second link 22 constituted by the support frame 55 . Therefore, the movement of the first link 21 during the folding operation of the stroller 10 is transmitted to the seat support body 40 via the second link 22 . Specifically, as shown in FIG. 5 , the seat support body 40 is rotated clockwise with respect to the handle 30 in a side view state, and approaches the handle 30 .

Moreover, as the front leg 60 and the rear leg 62 approach each other, the standing member 70 is bent so as to protrude downward from the connection position (position of the ninth rotation axis RA9 ) of the first standing element 71 and the second standing element 72 .

As a result of the above operation, the stroller 10 can be folded in the first folded state shown in FIG. 5 , and the dimensions in the front-rear direction and the vertical direction can be reduced. As shown in FIG. 5 , the stroller 10 in the first folded state can be made to stand up in a state where the stand member 70 is grounded to the pair of rear wheels 63 . In addition, in order to unfold|deploy the baby carriage 10 from the 1st folded state shown in FIG. 5 to the unfolded state, what is necessary is just to carry out the reverse procedure of the above-mentioned folding operation.

Next, the grip 30 is bent by rotating the second grip element 33 with respect to the first grip element 32 of the grip main body 31 about the bending axis BA. Thereby, the stroller 10 is brought into the second folded state shown in FIG. 6 , and the size in the vertical direction can be greatly reduced. As shown in FIG. 6 , the stroller 10 in the second folded state can be made to stand up in a state where the stand member 70 is grounded to the pair of rear wheels 63 . In addition, in order to unfold|deploy the stroller 10 from the 2nd folded state shown in FIG. 6 to the 1st folded state shown in FIG. 5, what is necessary is just to carry out the reverse procedure of the above-mentioned folding operation.

In the stroller 10 described above, the seat support body 40 is disposed above the handle 30 for folding the stroller body 20 , the front legs 60 and the rear legs 62 constituted by links. In particular, the seat support body 40 is positioned above the first link 21 and further positioned above the third link 23 . Therefore, the seat support body 40 can be held in a high position. By raising the holding position of the seat support body 40 , the infant sitting on the seat support body 40 can be separated from the walking surface of the stroller 10 . Thereby, the infant riding on the stroller 10 can be protected from radiant heat from the walking surface, dust on the walking surface, and the like, and the riding comfort can be improved.

On the other hand, the stroller body 20 includes a first folding restricting member 26 and a second folding restricting member 27 in order to restrict an undesired folding operation. The first folding restricting member 26 is supported by the handle 30 and restricts the relative movement of the handle 30 and other components. The first folding restricting member 26 restricts the relative movement of the handle 30 and any other component, for example, restricts the relative movement between the first to fourth links 21 to 24 , the front leg 60 and the rear leg 62 and the handle 30 . operation, so that the folding operation of the stroller 10 can be restricted. The second folding restricting member 27 is supported by the grip 30 and restricts the bending of the grip 30 .

In the stroller 10 shown in the figure, the first folding restricting member 26 supported by the handle 30 is biased downward by a biasing mechanism not shown. As shown in FIGS. 7A to 7C , the The folding restricting member 26 protrudes downward from the handle 30 and enters into the recess 62c provided in the rear leg 62. The relative movement of the handle 30 and the rear leg 62 is restricted by the engagement of the first folding restricting member 26 supported by the handle 30 with the recessed portion 62 c of the rear leg 62 . In addition, in the illustrated example, as shown in FIGS. 7A to 7B , the first folding restricting member 26 protrudes inward in the width direction from the grip 30 . The first folding restricting member 26 that is pressed downward enters the cutout 24 a of the fourth link 24 formed by the bracket member 67 . The relative movement of the grip 30 and the fourth link 24 is restricted by the engagement of the first folding restricting member 26 supported by the grip 30 with the cutout 24 a of the fourth link 24 . According to such a first folding restricting member 26 , it is possible to restrict the folding operation of the stroller 10 accompanying the relative rotation of the handle 30 with respect to the seat support body 40 . The restriction of the folding movement by the first folding restricting member 26 is released by lifting the first folding restricting member 26 .

As shown in FIGS. 7A to 7C , the second folding restricting member 27 is arranged at the portion where the first grip element 32 and the second grip element 33 of the grip body 31 are connected. The first grip element 32 has a first rotation case 32a, and the second grip element 33 has a second rotation case 33a. The first rotating casing 32a and the second rotating casing 33a are rotatably connected to each other about the bending axis BA. The second folding restricting member 27 is provided in a casing formed by the first rotating casing 32a and the second rotating casing 33a. The first rotating casing 32a and the second rotating casing 33a are arranged in the width direction. The second folding restricting member 27 is held by the second rotating housing 33a so as to be movable in the width direction. The second folding restricting member 27 is biased toward the first rotation case 32 a in the width direction through the biasing mechanism 35 . The second folding restricting member 27 is positioned so as to straddle both the first rotating case 32a and the second rotating case 33a, thereby allowing the first rotating case 32a and the second rotating case 33a to have the bending axis BA as the center. Relative rotation is restricted. Therefore, by pressing the second folding restricting member 27 into the second rotating housing 33a, the restriction on the bending of the grip 30 can be released.

The first folding restricting member 26 and the second folding restricting member 27 can be operated through the remote control device 34 provided in the grip 30 . The remote operation device 34 has, for example, an operation portion 34a configured as an operation lever. The operation of the operation portion 34 a is transmitted to both the first folding restricting member 26 and the second folding restricting member 27 via the transmission mechanism 38 . That is, by operating the operation part 34a of the remote control device 34, the restrictions on both the first folding restricting member 26 and the second folding restricting member 27 can be released.

In the example shown in FIGS. 7A to 7C , the transmission mechanism 38 includes a first transmission wire 38A, a second transmission wire 38B, and an intermediate operation member 38C. The intermediate operation member 38C is arranged between the first transmission wire 38A and the second transmission wire 38B. The first transmission wire 38A is connected to the operation portion 34a of the remote control device 34 and the intermediate operation member 38C at both ends thereof. The second transmission wire 38B is connected to the operation portion 34a of the remote control device 34 and the first folding restricting member 26 at both ends thereof. The intermediate operation member 38C is located in a casing formed by the first rotating casing 32a and the second rotating casing 33a. In this case, the intermediate operation member 38C is located at a position adjacent to the second folding restricting member 27 in the width direction.

In addition, the 1st transmission wire 38A and the 2nd transmission wire 38B are respectively arrange|positioned in the cylindrical member which is not shown in figure. In addition, both ends of the cylindrical member (not shown) are fixed to the grip 30 . Both ends of the first transmission wire 38A and the second transmission wire 38B are located outside the tubular member, but the arrangement of the tubular member is adjusted so as not to loosen outside the tubular member. Therefore, the movement amount of the intermediate operation member 38C and the movement amount of the first folding restricting member 26 are determined according to the operation amount of the operation portion 34a of the remote operation device 34 .

The intermediate operation member 38C is held in the first rotation case 32a of the first grip element 32 . The intermediate operation member 38C moves in the longitudinal direction of the grip 30 by a length corresponding to the amount of operation of the operation portion 34a of the remote operation device 34 . Moreover, 38 C of intermediate|middle operation members have the convex part 38Ca which can contact the convex part 32b provided in the 1st rotation case 32a. By making the convex portion 38Ca of the intermediate operation member 38C and the The convex part 32b of the 1st rotation case 32a contacts, and 38 C of intermediate|middle operation members move to the width direction outer side in the 1st rotation case 32a. The second folding restricting member 27 is biased inward in the width direction by the biasing mechanism 35, and is pressed toward the intermediate operation member 38C. By moving the intermediate operation member 38C to the outside in the width direction, the second folding restricting member 27 can be pushed to the outside in the width direction, and the restriction on the bending of the grip 30 by the second folding restricting member 27 can be released.

In the stroller 10 shown in the figure, when the operation part 34a of the remote operation device 34 is operated by the first operation amount (see FIG. 7B ), the bending of the grip 30 is restricted by the second folding restricting member 27 . The restriction of the rotation of the grip 30 with respect to the first link 21 by the first folding restricting member 26 is released. Specifically, when the operation part 34a is operated by the first operation amount from the state shown in FIG. 7A to the state shown in FIG. 7B , the first folding restricting member 26 can be lifted via the transmission mechanism 38 . Thereby, the 1st folding restricting member 26 can be lifted up from the recessed part 62c of the rear leg 62, and the 1st folding restricting member 26 can be lifted up from the notch 24a of the 4th link 24. At this time, as shown in FIG. 7B , the convex portion 38Ca of the intermediate operation member 38C is not yet in contact with the convex portion 32b of the first rotating housing 32a. Therefore, the intermediate operation member 38C and the second folding restricting member 27 do not move in the width direction. The second folding restricting member 27 is located across the first pivoting case 32a and the second pivoting case 33a, and restricts the bending of the grip 30 .

Next, when the operation part 34a is further operated from the state shown in FIG. 7B to the state shown in FIG. 7C , the intermediate operation member 38C can be further lifted up via the transmission mechanism 38 , so that the intermediate operation member 38C can be moved further. The convex portion 38Ca of the second rotating housing 33a is in contact with the convex portion 32b. The intermediate operation member 38C can be moved to the outer side in the width direction by the contact between the convex portion 38Ca and the convex portion 32b. Thereby, the 2nd folding restricting member 27 can be press-fitted into the 2nd rotation housing 33a via the intermediate|middle operation member 38C, and the bending restriction|limiting of the grip 30 can be cancelled|released. That is, in the state shown in Fig. 7A From the state shown in FIG. 7B , when the operation portion 34a of the remote control device 34 is operated with a second operation amount larger than the first operation amount, the first folding restricting member 26 can release the relative position of the grip 30 to the first folding control member 26 . The rotation of the link 21 is restricted, and the restriction of the bending of the grip 30 by the second folding restricting member 27 can be released.

In the above-described embodiment, the stroller 10 includes: a handle 30; a seat support body 40 that is rotatably connected to an intermediate portion in the vertical direction of the handle 30 to support the buttocks of the infant; and a first link 21 that The lower end portion of the handle 30 is rotatably connected; the front leg 60 is rotatably connected to the first link 21 ; the second link 22 is rotatably connected to the seat support body 40 and the first link 21 . According to such an embodiment, the seat support body can be arranged at a position above the first link extending between the front leg and the lower end portion of the grip. Furthermore, the seat support body can be supported from below through the second link which can perform the folding operation of the stroller. That is, the seat support body can be stably held at a high position. Thereby, it is possible to effectively protect the infant riding on the stroller from the influence of dust, temperature, etc. on the running surface (road surface), and it is possible to effectively improve the riding comfort.

In the specific example of one embodiment described above, the handle 30 can be bent at a position above the position where it is connected to the seat support 40 .

In this stroller 10, the development of the stroller 10 can be realized by operating one remote control device 34. Both the open state and the extended state of the grip 30 are released. Therefore, the operability of the stroller 10 which can be reduced in size during the folding operation can be improved.

In the specific example of the above-described one embodiment, when the remote control device 34 is operated with the first operation amount, in a state where the bending of the grip 30 is restricted by the second folding restricting member 27, the restriction by the first folding is released. The member 26 restricts the rotation of the grip 30 with respect to the first link 21 . In addition, when the remote control device 34 is operated by the second operation amount larger than the first operation amount, the restriction of the rotation of the grip 30 relative to the first link 21 by the first folding restricting member 26 is released, and the first folding control member 26 is released. 2. The folding restricting member 27 restricts the bending of the grip 30. That is, after the operation of the remote control device 34 is started, the stroller 10 can be folded first. After that, the grip 30 can be bent by further continuing to operate the remote control device 34 . Therefore, the size of the stroller 10 in the folded state can be reduced stepwise according to the storage space of the stroller 10 and the like. In addition, since the bending of the handle 30 is restricted at the start of the folding operation of the stroller 10 , the stroller 10 can be stably folded while the handle 30 is grasped.

In the specific example of the above-described one embodiment, in the side view of the stroller 10, the length LU from the bendable position of the handle 30 to the upper end is greater than the length LU from the bendable position of the handle 30 to the lower end Length LL is long. According to such a stroller 10 , the folding size of the stroller 10 can be significantly reduced by bending the handle 30 .

In the specific example of the above-described one embodiment, the stroller 10 further includes the seat member 15 provided on the seat support body 40 . The seat member 15 includes a side member 16 that is attached to the seat support body 40 and the handle 30 and faces the infant from the side. The bendable position of the handle 30 is at the position where the seat support body 40 is connected and the side member is connected. 16 positions. In such a stroller 10, it is possible to become an infant The height position of the living space allows the handle 30 to flex. Therefore, by bending the handle 30, the folded size of the stroller 10 can be significantly reduced.
