As shown in FIGS. 2 to 4 , the frame body 108 may include a frame 112 fixed to the seat cloth 110 , a bottom frame section 114 and a back frame section 116 .

The frame 112 can surround a central area, and the seat fabric 110 can be stretched on the central area to form a child's seating support. The surrounding frame 112 may include two frame bodies 118 , 120 , and the two frame bodies 118 , 120 are pivotally connected through two pivot structures 122 . The two pivot structures 122 define the pivot P1. Each frame body 118, 120 is, for example, semi-elliptical in shape. When the child moving device 100 is unfolded, the frame body 118 can extend downward from the pivot P1, and the frame body 120 can extend upward from the pivot P1. The two pivot structures 122 can respectively connect the left and right sides of the frame body 118 , 120 . The handle 111 can be arc-shaped, and two sides of the handle 111 are respectively pivotally connected to the frame body 120 of the surrounding frame 112 along the pivot axis P1 through two pivot structures 123 .

The chassis section 114 is substantially elongated and can extend along the longitudinal axis S from the rear side 104A of the seat 104 to the front side 104B of the seat 104 in the central region of the seat 104 . The chassis section 114 has a rear end portion 114A and a front end portion 114B corresponding respectively to the rear side 104A and the front side 104B of the seat 104, and the chassis section 114 is connected to the upright 106 between the rear end portion 114A and the front end portion 114B. connected at the top. The backrest frame section 116 is generally in the shape of a strip, and the backrest frame section 116 is located behind the seat support portion formed by the seat cloth 110 , that is, behind the child's back. The back frame section 116 can stand upward from the bottom frame section 114 and has a lower end portion 116A and an upper end portion 116B. The front end portion 114B of the bottom frame section 114 can be pivotally connected to the lower end portion of the frame body 118 via a hinge 124 , wherein the hinge 124 can define a pivot axis P2.

The heights of the two side leaning plates 134 roughly correspond to the shoulders of children, and the two side leaning plates 134 can symmetrically extend downwards from the left and right sides of the frame body 120 toward the central area of the frame body 120 . The two side walls 132A of the seat panel 132 assist in centering the child's legs and buttocks, while the two side panels 134 assist in centering the child's chest and head. Thereby, the child can be positioned in the central area of the seat 104 , so that the swing of the seat 104 around the central axis of the base 102 is more balanced.

The frame of the seat 104 can be unfolded for use, and can be folded for convenient storage. 1 to 4 are schematic diagrams illustrating the seat 104 in an unfolded state, and FIG. 5 is a schematic diagram illustrating the seat 104 in a folded state. Referring to FIGS. 2 to 4 , when the seat 104 is unfolded for use, the frames 118 , 120 can be unfolded and extend along substantially the same plane to define an ellipse. Referring to FIG. 5 , when the seat 104 is in the folded state, the frame body 120 and the handle 111 can be folded onto the frame body 118 respectively. In addition, the two pivot structures 122 , 123 include a plurality of latches that can rotatably lock the frame 112 and the handle 111 respectively.

2 to 4 , FIG. 6 is a cross-sectional view illustrating the structures of the pivot structures 122 , 123 respectively disposed on the left and right sides of the seat 104 , and FIG. 7 is a schematic diagram illustrating the detailed structure of the pivot structure 122 . The pivot structures 122 , 123 disposed on the left side of the seat 104 and the pivot structures 122 , 123 disposed on the right side of the seat 104 may have similar structures. Referring to FIGS. 2 to 4 , FIGS. 6 and 7 , the pivot structure 122 may include two coupling housings 136 and 138 , a latch 140 , a spring 142 and a release 144 . Each coupling housing 136, 138 may have a circular shape. The coupling shell 136 is fixedly connected to the end of the frame body 118 , and the coupling shell 138 is fixedly connected to the end of the frame body 120 . The coupling housing 136 can be pivotally connected to the first side of the coupling housing 138 via the pivot P1. The combination of the coupling housings 136 , 138 can at least partially define an inner cavity 139 , and the latch 140 is movably assembled in the inner cavity 139 . For clarity, the coupling housing 136 fixed to the frame body 118 is omitted in FIG. 7 , so as to more clearly show the relative position and interaction between the latch 140 and the coupling housing 138 .

The latch 140 may have a disc shape approximately centered on the pivot P1. The latch 140 can be integrally formed and has two opposite sides 140A and 140B. The central hole 146 passes through the latch member 140 and is exposed on the two sides 140A and 140B. The circular outer edge of the latch member 140 is provided with a plurality of protruding teeth 147A, 147B, 147C, 147D. The protruding teeth 147A, 147B, 147C, 147D are distributed around the pivot P1 and protrude radially outward. According to an embodiment, the protruding teeth 147A, 147B may be disposed at positions opposite to each other along a first diameter direction, and the protruding teeth 147C, 147D may be disposed at positions opposite to each other along a different second diameter direction. The latch member 140 can further have a channel 148 in a ring shape around the pivot P1 at its side 140A. The cross-section of the channel 148 may have a V-shape, which may define two slopes 148A.

Referring to FIG. 6 and FIG. 7 , a protruding shaft body 150 can be fixed inside the coupling housing 138 , which corresponds to the center position of the pivot P1 . When the latch 140 is assembled in the inner chamber 139 , the shaft body 150 passes through the central hole 146 of the latch 140 to movably support the latch 140 . Thus, the latch 140 can slide in the inner cavity 139 along the pivot P1 between the locked state and the unlocked state, wherein when the latch 140 is in the locked state, the locking frames 118, 120 are in the unfolded state When the latch 140 is in the unlocked state, the frame bodies 118, 120 are allowed to fold and unfold. In addition, the assembled latch 140 and the coupling housing 136 are rotatably locked to each other (that is, the latch 140 and the coupling housing 136 cannot rotate relative to each other). Therefore, when the latch 140 is in the unlocked state, the coupling housing 138 can rotate around the pivot P1 relative to the coupling housing 136 and the latch 140 .

As shown in FIG. 7 , the interior of the coupling housing 138 may further include a plurality of notches, such as notches 152 , 154 , 156 , 158 , corresponding to the protruding teeth of the latch 140 and distributed around the pivot P1. According to one embodiment, the notches 152 , 154 are disposed at positions opposite to each other along a first diameter direction, and the notches 156 , 158 are disposed at positions opposite to each other along a different second diameter direction. The latch 140 can slide along the pivot P1 so that the teeth 147A, 147B, 147C, 147D engage or disengage from the notches 152 , 154 , 158 , 156 . For example, when the convex teeth 147A, 147B, 147C, and 147D engage with the notches 154, 152, 158, and 156 (as shown in FIG. When 120 is in the folded state, the protruding teeth 147A, 147B, 147C, 147D of the latch member 140 are respectively located in the notches 154, 152, 158, 156 (as shown in FIG. 10 ).

When the notches 152, 154, 156, 158 engage with the protruding teeth of the latch 140, they only prevent the frame body 120 from rotating relative to the frame body 118 in the folding direction, but allow the frame body 120 to rotate relative to the frame body 118 in the unfolding direction. . In order to achieve this purpose, one side of each notch 152, 154, 156, 158 can be defined by a stop side wall respectively (for example, stop side wall 152A of notch 152, stop side wall 154A of notch 154, notch The stop side wall 156A of the opening 156 and the stop side wall 158A of the notch 158), and each protruding tooth on the latch 140 can be prevented from rotating toward the folding direction by its corresponding stop side wall. In addition, one or more of the notches 152, 154, 156, 158 may also be bounded by a ramp on the opposite side of its stop sidewall (eg, ramp 154B of notch 154, ramp 156B of notch 156, and ramp 158 of notch 158). 158B), and when the frame body 120 rotates relative to the frame body 118 in the unfolding direction, the protruding teeth of the latch 140 can freely slide and contact the corresponding slope. When the frame body 120 is rotated relative to the frame body 118 to the unfolded state, the coupling shells 136 , 138 may further include mutually abutting structures to force the frame bodies 118 and 120 to stop in the unfolded state.

Referring to FIG. 6 , the spring 142 is assembled in the cavity 139 , and opposite ends of the spring 142 are respectively connected to the side 140B of the latch 140 and the inner sidewall of the coupling housing 136 . The spring 142 can urge the latch 140 to move toward the locked state to engage with the coupling housing 138 .

The operation of the release member 144 can overcome the elastic force of the spring 142 and drive the latch member 140 to release and move. The release member 144 may include an annular body 144A and an actuating portion 144B that are fixedly connected to each other, and the actuating portion 144B extends on one side of the annular body 144A. According to an embodiment, the release member 144 including the annular body 144A and the actuating portion 144B is integrally formed. The release member 144 is assembled with the coupling housing 138 , so that the release member 144 can slide relative to the coupling housing 138 and the frame 120 along a plane perpendicular to the pivot P1 . When the release part 144 is combined with the coupling housing 138, the shaft 150 passes through the ring body 144A, the actuating part 144B protrudes from the opening of the coupling housing 138, and the ring body 144A is located on the side of the latch 140 140A and coupling housing 138. The annular body 144A of the release member 144 is slidably in contact with the channel 148 on the side 140A of the latch member 140 .

In conjunction with FIG. 6 and FIG. 7 , FIG. 8 is a schematic diagram illustrating the pivotal joint structures 122 and 123 in an unlocked state. Referring to FIGS. 2 to 4 and 6 , it is assumed that the frame bodies 118 and 120 are locked in an unfolded state. The actuating portion 144B of the release member 144 is exposed on the lower side of the pivot structure 122 . In addition, the latch 144 can engage with the coupling housing 138 , as shown in FIGS. 6 and 7 .

Referring to FIG. 8 , to release the frame body 118 and the frame body 120 , the actuating portion 144B can be pressed toward the G direction, so that the release member 144 slides along the direction perpendicular to the pivot P1 . Due to the sliding contact between the annular body 144A of the release member 144 and the inclined surface 148A of the channel 148, the sliding of the release member 144 can push the latch member 140 to slide along the pivot P1 and disengage from the engagement with the coupling housing 138. combine. The unlocked frame body 120 can rotate relative to the frame body 118 toward the folding direction around the pivot P1. During the folding and rotating process, the unlocking part 144 and the frame body 120 rotate relative to the frame body 118 and the latching part 140 synchronously.

FIG. 10 is a schematic diagram illustrating the interior of the pivot structure 122 when the frame body 118 and the frame body 120 are in a folded state. In this state, the frame bodies 118 and 120 are approximately parallel. Moreover, the protruding teeth 147A, 147B, 147C, 147D of the latch 140 can engage with the notches 154 , 152 , 158 , 156 respectively. When the frame bodies 118 and 120 are to be unfolded, the caregiver can directly drive the frame body 120 to rotate relative to the frame body 118 to the unfolded state without operating the release member 144 .

In some usage situations, the caregiver may mistakenly think that the frame bodies 118 and 120 have been locked in the unfolded state, but actually the latch 140 has not been engaged with the coupling housing 138 . In order to prevent the surrounding frame 112 from being accidentally rotated from the unfolded state to the folded state, a safety mechanism can also be provided in the pivot structure 122 to force the frame body 120 to stop at an intermediate angular position, wherein the intermediate angular position is farther from the unfolded state than the folded state. The state is relatively close. Referring to FIGS. 7 , 10 and 11 , the safety mechanism may include at least one notch 159 disposed in the coupling housing 138 . The notch 159 can be at least partially defined between a blocking sidewall 159A and a slope 159B. The notch 159 is arranged radially relative to the pivot P1, and the radial direction of the notch 159 is different from the radial direction of the other notches 152 , 154 , 156 , 158 . According to an embodiment, the included angle A between the radial direction of the notch 156 and the radial direction of the notch 159 may be between about 35 degrees and about 45 degrees.

The position of the notch 159 corresponds to an intermediate angular position of the frame body 120 relative to the frame body 118 , and the intermediate angular position is between the unfolded state and the folded state, as shown in FIG. 11 . The included angle A between the intermediate angular position (as shown in FIG. 11 ) and the unfolded state (as shown in FIG. 7 ) of the frame body 120 may be between about 35 degrees and about 45 degrees. When the frame body 120 is at an intermediate angle position (as shown in FIG. 11 ), the elastic force of the spring 142 can force the protruding tooth 147C of the latch 140 to engage with the notch 159 . When the protruding tooth 147C is located in the notch 159 , the contact between the protruding tooth 147C and the stop side wall 159A can prevent the frame body 120 from rotating toward the folded state. If the frame body 120 is to be further rotated from the middle angle position to the folded state, the release member 144 must be operated first to drive the protruding tooth 147C out of engagement with the notch 159 . Then, as the frame body 120 is rotated beyond the intermediate angular position to the folded state, the protruding tooth 147C can travel over the notch 159 .

The inclination angle of the inclined surface 159B allows the frame body 120 to go over the notch 159 to unfold and rotate: as the frame body 120 rotates toward the unfolded state through an intermediate angular position relative to the frame body 118 , the protruding teeth 147C slidably contact the inclined surface 159B. Thus, the notch 159 effectively prevents the enclosure 112 from being accidentally rotated into the folded state, and allows normal unfolding operations.

Continuing to refer to FIG. 6 and FIG. 7, the pivot structure 123 connecting the handle 111 to the frame body 120 may include a coupling housing 138, another coupling housing 160 fixed to the end of the handle 111, a latch 162, A spring 164 and a release button 166 . The coupling housing 160 is fixed to one end of the handle 111 , and is pivotally connected to the second side of the coupling housing 138 (ie, the side opposite to the coupling housing 136 ) via the pivot P1 . Accordingly, the coupling housing 138 is sandwiched between the coupling housing 136 and the coupling body 160 . The coupling housings 138 and 160 can at least partially define an inner chamber 167 , and the latch member 162 and the spring 164 are assembled in the inner chamber 167 . The second sides of the coupling housing 160 and the coupling housing 138 are respectively provided with a plurality of internal teeth, such as the protruding teeth 138A of the coupling housing 138 and the protruding teeth 160A of the coupling housing 160 .

The latch 162 may have a disc 162A, and the disc 162A is centered on the pivot P1. The disk 162A may contain a plurality of radially outwardly protruding teeth 168 . Moreover, the latch 162 can also be fixed with an elongated portion 162B. The elongated portion 162B extends axially from the disc 162A along the pivot P1 , and the end portion of the elongated portion 162B is formed with one or more flanges 169 . According to an embodiment, the latch 162 (including the disk 162A, the elongated portion 162B, the protruding teeth 168 and the flange 169 ) can be integrally formed. The elongated portion 162B can be a hollow tube.

Referring to FIG. 6 , the second side of the coupling housing 138 can be fixedly connected to a protruding shaft 170 , wherein the shaft 170 is aligned with the pivot P1 . When the latch 162 is slidably assembled in the inner cavity 167, the shaft body 170 of the coupling housing 138 passes through the inside of the elongated portion 162B, and the elongated portion 162B axially passes through the annular body of the release member 144 along the pivot axis P1. 144A and the central hole 146 of the latch 140 . More specifically, side 140B of latch member 140 may define a surface 172 around central aperture 146, and elongate portion 162B may extend beyond surface 172 such that surface 174 defined by flange 168 faces the latch. Surface 172 of member 140. According to an embodiment, the surface 172 is formed, for example, by a protruding edge of the central hole 146 . When the latch 140 is released and displaced, the surface 172 of the latch 140 can interact with the surface 174 of the latch 162 , so that the two latches 140 , 162 can be released synchronously.

With the above combination, the latch 162 can slide in the inner cavity 167 along the pivot P1 between the locked state and the unlocked state, wherein the latch 162 can rotate the handle 111 when it is in the locked state. Locked to the frame body 120 , and the handle 111 is allowed to rotate relative to the frame body 120 around the pivot P1 when the latch 162 is in an unlocked state. More specifically, when the latch 162 is in the locked state, the protruding teeth 168 of the latch 162 can engage with the protruding teeth 138A of the coupling housing 138 and the protruding teeth 160A of the coupling housing 160 respectively, so as to block the handle 111 rotates relative to the frame body 120 around the pivot P1. When the latch 162 is slidably switched to the unlocked state, the protruding teeth 168 of the latch 162 disengage from the engagement with the protruding teeth 160A of the coupling housing 160, so that the handle 111 is relative to the frame body around the pivot P1 120 for rotation. Moreover, when the latch 162 is in the unlocked state, the latch 162 is rotationally locked to the coupling housing 138 and the frame body 120, and the latch 162 is rotationally unlocked relative to the coupling housing 160 and the handle 111. coupling (that is, the coupling housing 160 and the handle 111 will not rotate synchronously with the latch 162).

According to an embodiment, one or both of the magnetic elements 188A, 188B are electromagnets, and the magnetic element 188C fixed on the rod body 186 is a permanent magnet. During the lateral swing of the seat 104 around the pivot Z, the magnetic force will be generated when the magnetic element 188C is close to any one of the two magnetic elements 188A and 188B, and the swing of the seat 104 will continue to be maintained through the magnetic force. . Seat 104 swings to help soothe the child and can swing within the area occupied by base 102 , which reduces the size of children's mobility device 100 .

When the seat 104 does not need to swing sideways, the present invention can also use a locking mechanism to lock the seat 104 at the center position of the base 102, that is to say, make the two longitudinal axes S, B aligned up and down with each other. When the seat 104 is locked in a centered position relative to the base 102, the child mobility device 100 can be more easily transported.

13 and 14 are schematic views of the locking mechanism provided in the child moving device 100 for preventing the seat 104 from rotating around the pivot Z. FIG.

More specifically, the anchor 190 may be a single element that is pivotally coupled to the chassis section 114 in an easily accessible position. According to one embodiment, the anchoring member 190 is, for example, spaced from the column 106 and disposed adjacent to the rear end portion 114A of the chassis section 114 . The anchor 190 is movable relative to the seat 104 between a locked position (shown in FIG. 13 ) and an unlocked position (shown in FIG. 14 ). The anchor 190 spans the gap between the bottom of the seat 104 and the upper surface 103 of the base 102 when in the locked position. The anchor 190 is retracted to a position close to the bottom of the seat 104 when in the unlocked position.

When the anchor 190 is in the locked position, the anchor 190 protrudes downward from the bottom of the seat 104 and engages with the upper surface 103 of the base 102 . More specifically, the upper surface 103 of the base 102 can be provided with a groove 192, the groove 192 is substantially aligned with the longitudinal axis B of the base 102, and the anchor 190 can engage with the groove 192 when it is in the locked position. . According to one embodiment, the groove 192 may be located between the column 106 and the rear side 102A of the base 102 , corresponding to the area where the distance between the bottom of the seat 104 and the upper surface 103 of the base 102 is relatively small. The anchor point formed when the anchor member 190 is engaged with the groove 192 is located adjacent to the rear side of the seat 104 (particularly near the rear end portion 114A of the chassis section 114 ) and generally opposite the longitudinal axis B of the base 102 together. Accordingly, the seat 104 is rotationally lockable with the base 102 in a centrally aligned position (ie, the longitudinal axis B of the base 102 is generally aligned with the longitudinal axis S of the seat 104 shown in FIG. 1 ).

Referring to FIG. 14 , when the anchor member 190 is rotated to the unlocked position, it can disengage from the groove 192 of the upper surface 103 , so that the seat 104 can rotate around the pivot Z relative to the base 102 .

It is worth mentioning that in the present invention, the anchor member can also be combined with the base 102 to realize an anchor point that prevents the seat 104 from rotating around the pivot Z. 15 and 16 are schematic diagrams illustrating another locking mechanism provided in the child moving device 100 to prevent the seat 104 from rotating around the pivot Z. FIG. The locking mechanism shown in FIGS. 15 and 16 includes an anchor 194 movably assembled to the base 102 . More specifically, the anchor 194 can be a single element and can be pivotally connected to the housing 176 of the base 102 . The anchor 194 may be disposed between the rear side 102A of the base 102 and the post 106 and generally aligned with the longitudinal axis B of the base 102 . The anchor 194 is movable relative to the base 102 between a locked position (shown in FIG. 15 ) and an unlocked position (shown in FIG. 16 ). The anchor 194 spans the gap between the upper surface 103 of the base 102 and the bottom of the seat 104 when in the locked position. When the anchor member 194 is in the unlocked position, it is retracted to a position close to the upper surface 103 of the base 102 .

When the anchor 194 is in the locked position, the anchor 194 protrudes upwards from the upper surface 103 of the base 102 and engages with the bottom of the seat 104 . More specifically, the anchor 194 can be engaged with a groove formed in the chassis section 114 adjacent to the rear end 114A thereof. The anchor point formed by the anchor member 194 when engaged with the chassis section 114 is located adjacent the rear side of the seat 104 and is generally aligned with the longitudinal axis B of the base 102 . Accordingly, the seat 104 is rotationally lockable with the base 102 in a centrally aligned position.

Referring to FIG. 16 , when the anchor member 194 is rotated to the unlocked position, it can be disengaged from the chassis section 114 , so that the seat 104 can rotate around the pivot Z relative to the base 102 . The anchor 194 in the unlocked position can be conveniently folded to the upper surface 103 of the base 102 , for example, the anchor 194 can be accommodated in a recess of the upper surface 103 .

The children's mobile device described above has the advantage of being convenient to fold its rigid frame. Furthermore, the child mobility device may also have easily accessible anchors to lock the seat in a central position to facilitate transport of the child mobility device.

What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
