Thereby, the engagement with the engagement hole 133 can be released, and the seat 40 can be removed from the holding member 130 .

6B and 6C, the connecting member 50, particularly the protrusion 53 and the operating device 54, will be described in more detail. 6B and 6C are views showing the inside of the connection member 50 . As shown in FIG. 6B , the connecting member 50 has an accommodating portion 50 a capable of accommodating the protruding portion 53 and the operating device 54 . The accommodating portion 50 a constitutes the connecting portion 51 and the mounting portion 52 . At the portion that becomes the connecting portion 51 of the accommodating portion 50a In addition, in the unfolded state of the stroller 10, a first opening 50b is provided in a region from one side in the front-rear direction (the side of the side surface 52b) toward the upper side. Moreover, the 2nd opening part 50c is provided in the part which becomes the side surface 52b of the attachment part 52 of the accommodating part 50a.

On the inner surface of the attachment portion 52, a projection guide wall 52g extending in the front-rear direction in the unfolded state of the stroller 10, and an action portion guide wall 52h extending in the vertical direction in the unfolded state of the stroller 10 are formed.

The protruding portion 53 is a plate-shaped member. The protruding portion 53 is arranged in the mounting portion 52 so as to extend in the front-rear direction in the unfolded state of the stroller 10 and to be movable along the protruding portion guide wall 52g. The protruding portion 53 imparts potential energy to the second opening portion 50 c by the protruding portion imparting mechanism 53 s arranged in the mounting portion 52 . Therefore, when no force is applied to the protruding portion 53, one end 53a of the protruding portion 53 on the side of the second opening portion 50c protrudes toward the outside of the mounting portion 52 through the second opening portion 50c. On the other end 53b (end on the side surface 52d side) of the protruding portion 53, there is formed a convex portion 53c that protrudes outward in the width direction of the stroller 10 and that the operating device 54 acts on. The surface of the convex part 53c facing the second opening part 50c is the working surface 53d on which the operation device 54 acts. In the unfolded state of the stroller 10, the action surface 53d is inclined upward toward the second opening 50c.

The operation device 54 includes an operation lever 54a and an action portion 54b that acts on the protruding portion 53 in accordance with the operation of the operation lever 54a. The operation lever 54a is rotatably connected to a shaft member 54x extending in the accommodating portion 50a in the width direction of the stroller 10 at the middle portion thereof. One end 54c of the operating rod 54a, It is exposed to the outside of the connection part 51 through the first opening part 50b. The other end 54d of the operation lever 54a is provided with the convex part 54e extended to the width direction outer side of the stroller 10. As shown in FIG. In the connection part 51, the operation lever imparting potential energy mechanism 54s is arrange|positioned. The operation lever imparting potential energy mechanism 54s can maintain the operation lever 54a in the state shown in FIG.

The action portion 54b extends substantially in the up-down direction in the unfolded state of the stroller 10 . The upper end 54f of the action part 54b is provided with the opening part 54g which penetrates the width direction of the stroller 10. As shown in FIG. The convex part 54e of the operation lever 54a is penetrated in the opening part 54g. Then, the upper end 54f of the action portion 54c is swingably connected to the operation lever 54a. The lower half of the action portion 54c extends along the action portion guide wall 52h and moves along the action portion guide wall 52h. The lower end 54i of the action portion 54c is provided with an inclined surface 54h inclined corresponding to the action surface 53d of the protruding portion 53 . In the unfolded state of the stroller 10, the inclined surface 54h is inclined upward toward the second opening 50c.

In this way, when the operating device 54 and the protruding portion 53 do not apply force to the operating rod 54a, the operating rod 54a is maintained at the position shown in FIG. 6B because the operating rod 54s applies the potential energy mechanism 54s, whereby the action portion 54b is also maintained. in the position shown in Figure 6B. At this time, since the acting portion 54b does not act on the protruding portion 53, the protruding portion 53 also maintains the position shown in FIG. 6B because the protruding portion imparts the potential energy mechanism 53s. Therefore, one end 53a of the protruding portion 53 protrudes from the mounting portion 52 through the second opening portion 50c. On the other hand, when a force is applied to the operation lever 54a and the operation lever 54a is rotated from the position shown in FIG. 6B to the position shown in FIG. 6C, the other end 54d of the operation lever 54a is connected to the The action portion 54b rises, and the inclined surface 54h rises. As a result, the working surface 53d of the protruding portion 53 is pressed in a direction away from the second opening portion 50c, and one end 53a of the protruding portion 53 is retracted into the mounting portion 52. As shown in FIG. In other words, in the unfolded state of the stroller 10, the rotational motion of the operating lever 54a is converted into the vertical linear motion of the action portion 54b, and further, the forward and rearward linear motion of the protruding portion 53 is converted. Thereby, by operating the operating lever 54a, the engagement between the protruding portion 53 of the connecting member 50 and the engaging hole 133 of the holding member 130 can be released.

In addition, the seat seat 40 can be connected to the holding member 130 even if the front and rear directions of the seat seat 40 are switched. Therefore, in FIG. 1 , although the seat 40 is connected to the holding member 130 in a state where the head-side frame member 44 is arranged on the side of the handle 15 , it may be in a state where the foot-side frame member 45 is arranged on the side of the handle 15 . Connected with the holding member 130 .

The connecting member 46 of the main frame member 41 and the connecting portion 51 of the connecting member 50 are rotatably connected. The connection member 46 and the connection portion 51 are rotatable around the rotation axis As extending in the width direction of the stroller 10 . Thereby, the angle of the main frame member 41 with respect to the traveling surface S can be changed in a state where the seat 40 is supported by the stroller body 11 . Thereby, the angle (reclining angle) of the back 92 of the seat 90 can be changed. In addition, the relative rotation between the connecting member 46 and the connecting member 50 is normally restrained. However, by operating the operation part 48 (refer FIG. 1 etc.) provided in the main frame member 41, the connection member 46 can be rotated with respect to the connection member 50.

7 and 8, the connection structure of the connection member 46 and the connection part 51 is demonstrated. FIG. 7 shows the connecting portion of the connecting member 46 and the connecting portion 51 . Moreover, FIG. 8 shows the connection part of the connection member 50 and the connection member 46. As shown in FIG. As shown in FIG. 7 , in the connecting member 46 , a fitting member 49 that is fitted to the inner peripheral surface of the connecting member 46 is fitted. The fitting member 49 is in the shape of a gear in a side view, and has a concavo-convex structure on its outer peripheral surface. On the outer peripheral surface of the fitting member 49 , 18 projections are provided on one circumference with the rotation axis As as the center at a distance of 20° from the central angle. Then, the inner peripheral surface of the connecting member 46 has a concavo-convex structure corresponding to the concavo-convex structure of the outer peripheral surface of the fitting member 49 . As shown in FIG. 8 , the connecting portion 51 also has a concave-convex structure corresponding to the concave-convex structure on the outer peripheral surface of the fitting member 49 on its inner peripheral surface. Furthermore, the fitting member 49 is also fitted into the connecting portion 51 of the connecting member 50 . That is, the fitting member 49 is fitted to the connecting member 46 on one side (inner side) in the width direction of the stroller 10 , and is fitted to the connecting portion 51 on the other side (outer side). Thereby, the connecting member 46 is restrained with respect to the connecting portion 51 .

In the connecting member 46, a pressing member (not shown) that presses the fitting member 49 into the connecting portion 51 is provided. This pressing member is actuated by operating the operating portion 48 to press-fit the fitting member 49 into the connecting portion 51 . Thereby, the fitted state of the connection member 46 and the fitting member 49 can be released. Then, the restraint of the connection portion 51 by the connection member 46 can be released, and the connection member 46 can be rotated relative to the connection member 50 .

Here, the fitting member 49 is given potential energy toward the connecting member 46 side. In addition, since the concave-convex structure of the fitting member 49 is point-symmetric around the rotation axis As, when the connecting member 46 is rotated around the rotation axis As by a specific angle (for example, 20° in the example shown in the figure) , 40°, 60°), the position of the concavity and convexity on the inner peripheral surface of the connecting member 46 corresponds to the concavity and convexity on the outer peripheral surface of the fitting member 49 (the position where the fitting member 49 can be fitted). Therefore, at this time, when the operation of the operation portion 48 is completed, the fitting member 49 moves toward the connecting member 46 and is fitted to both the connecting member 46 and the connecting portion 51 again. Thereby, the relative rotation of the connection member 46 and the connection part 51 can be restrained.

In addition, when the main frame member 41 is rotated relative to the connecting member 50 , not only the back portion 92 of the seat 90 but also the seat portion 91 is inclined relative to the traveling surface S. As shown in FIG. Therefore, the seat 40 further includes a seat angle adjusting device 70 for adjusting the angle of the seat 91 of the seat 90 relative to the traveling surface S. As shown in FIG. Thereby, even if the main frame member 41 is inclined with respect to the traveling surface S, the angle of the seat portion 91 with respect to the traveling surface S can be made a desired angle (for example, horizontal).

Specifically, as shown in FIGS. 1 and 9 , the seat angle adjustment device 70 includes a first cord member 71 and a second cord member 72 . As shown in FIG. 1 , one end portion of the first string member 71 is fixed to the frame side portion 45 a on one side (left side) of the foot-side frame member 45 . The first string member 71 passes through the inside of the side cloth portion 42b on one side (left side) of the cloth material 42, the lower region of the bottom cloth portion 42a, and the inside of the other side (right side) side cloth portion 42b. Then, the first cord member 71 extends from the inside of the cloth material 42 on the other side (right side) of the seat 40 . Here, the first rope member guide 74 is fixed to the frame side portion 45 a on the other side (right side) of the foot side frame element 45 . The first string member 71 extending from the cloth material 42 passes through the string hole of the first string member guide 74 . In the other end part of the 1st rope member 71, the 1st connection tool 71a for connecting the 2nd rope member 72 mentioned later is provided. By pulling the other end portion of the first string member 71, as shown in FIG. 10, the bottom cloth portion of the cloth material 42 can be lifted from below. Thereby, the angle of the seat part 91 with respect to the traveling surface S can be changed. One end portion of the second cord member 72 is fixed to the frame side portion of the other side (right side) of the head-side frame member 44 44a. The second string member 72 extends from the inside of the cloth material 42 . Here, the second rope member guide 75 is fixed to the frame side portion 44a on the other side (right side) of the head-side frame element 44 . The second string member 72 extending from the cloth material 42 passes through the string hole of the second string member guide 75 . On the other end portion of the second string member 72, a second connector 72a for connecting to the first connector 71a of the first string member 71 is provided. The length of the second rope member 71 is much shorter than that of the first rope member 71 . Therefore, when the other end portion of the first string member 71 and the other end portion of the second string member 72 are connected by the connectors 71a and 72a, the first string member 71 is pulled to maintain the bottom of the cloth material 42. A state in which the cloth portion 42a is lifted from below (refer to FIG. 10 ). With the seat angle adjusting device 70 as described above, even if the seat 40 is rotated to be inclined with respect to the travel surface S, the seat portion 91 can be made at a desired angle (eg, horizontal) with respect to the travel surface S.

The adjustment device 70 further includes a third cord member 73 that can further adjust the angle (inclined angle) of the back portion 92 . As shown in FIGS. 1 and 9 , the third string member 73 is a frame side portion 44 a whose one end portion is fixed to the head side frame element 44 side (left side). The third string member 73 passes through the inside of the side cloth portion 42b on one side (left side) of the cloth material 42, the lower region of the bottom cloth portion 42a, and the inside of the other side (right side) side cloth portion 42b. Further, the other end portion of the third string member 73 is fixed to the frame side portion 44 a on the other side (right side) of the head-side frame element 44 . An adjustment tool 73a is provided in the middle portion of the third cord member 73 . The adjustment tool 73a can adjust the length from one end portion of the third cord member 73 to the adjustment tool 73a, and the length from the other end portion of the third cord member 73 to the adjustment tool 73a. By shortening the length from one end portion of the third cord member 73 to the adjustment tool 73a, and the length from the other end portion of the third cord member 73 to the adjustment tool 73a 10, the bottom cloth part 42a of the cloth material 42 can be lifted from below. Thereby, the angle of the back 92 of the seat 90 can be changed.

The stroller 10 (the stroller body 11 ) having the overall configuration as described above can be folded by rotating the respective constituent members relative to each other as follows.

First, in the stroller 10 in the unfolded state, the convex portion 18b of the operation member 18 is received and accommodated in the concave portion 19a of one of the locking members 19 . Thereby, the relative rotation between the second link member 32 and the handle 15 is restrained. Here, by operating the remote control device 18a, the engagement state of the second link member 32 and the penetration locking member 19 of the handle 15 is released. Specifically, the operation member 18 is moved upward by the remote operation device 18a. Thereby, the fixation of the handle 15 by the second link member 32 is released, and the fixation of the other components by the second link member 32 is released. In addition, at this time, the lower end portion of the handle 15 is engaged with the engaging member 17 provided in the middle portion of the rear leg 24 .

From this state, the handle 15 disposed at the rear position is temporarily pulled up rearward and upward, and the engagement of the lower end portion of the handle 15 with the rear leg 24 is released. Then, the handle 15 is pressed downward. At this time, the first link member 31 rotates clockwise in FIGS. 2 and 4 with respect to the rear leg 24 . Thereby, the handle 15 and the rear leg 24 are brought closer (refer to FIGS. 11 and 12 ). Furthermore, when the handle 15 is pressed downward, the second link member 32 operates together with the handle 15 . Thereby, the second link member 32 rotates clockwise in FIGS. 2 and 4 with respect to the rear leg 24 . With this movement of the second link member 32, the third link member 33 is pulled rearward. When the third link member 33 is pulled backward, the front leg 22 will be pulled against the rear leg 24 while rotating counterclockwise in FIGS. 2 and 4 . Near the rear leg 24 (see FIGS. 11 and 12 ). From the above, as shown in FIGS. 11 and 12 , the size of the stroller 10 in the front-rear direction can be reduced in size. In addition, at this time, as described above, the arrangement position of the handle 15 can be lowered. As a result, not only the size in the front-rear direction of the stroller 10 but also the size in the vertical direction of the stroller 10 can be reduced in size.

On the other hand, in order to unfold the stroller 10 (the stroller body 11 ) from the folded state, it is only necessary to perform an operation opposite to the above-described folding operation.

As described above, when the handle 15 is lowered downward while approaching the rear leg 24 during the deformation of the stroller 10 from the unfolded state to the folded state, the first link body portion 31a is tilted rearward. At this time, the holding member 130 fixed to the first link body portion 31a also falls backward together, and the connecting member 50 connected to the holding member 130 also falls in the order of FIGS. 2 and 4 together with the holding member 130 . Rotate clockwise while dumping backwards. Thereby, the seat 40 (particularly, the main frame member 41 ) moves rearward, and the degree of movement is such that the connecting member 50 falls rearward. Thereby, even in the folded state, the stroller body 11 can stably support the seat 40, and the stroller 10 in the folded state can stand on its own.

In particular, in the illustrated example, in the folded state, the connection position between the connection member 50 and the main frame member 41 (specifically, the connection portion 51 of the connection member 50 ) is located between the rear leg 24 and the handle 15 (refer to FIG. 11 ). In such a stroller 10, the state in which the stroller 10 in the folded state stands on its own can be made more stable. In addition, in the illustrated example, in the folded state, the connection position between the connection member 50 and the main frame member 41 (specifically The connecting portion 51) of the connecting member 50 is located between the front end portion of the front wheel 25a and the rear end portion of the rear wheel 26 in the front-rear direction (see FIG. 11). In such a stroller 10, the state in which the stroller 10 in the folded state stands on its own can be made more stable.

Moreover, the seat 40 has the connecting member 50 which is detachably connected to the holding member 130 . The connecting member 50 is connected to the holding member 130 from above in the unfolded state of the stroller 10 (see FIG. 2 ), but is connected to the holding member 130 from the rear in the folded state of the stroller 10 (see FIG. 11 ). That is, when the holding member 130 and the connecting member 50 are deformed from the unfolded state to the folded state of the stroller 10, the first link main body portion 31a is tilted rearwardly and is tilted backward (see FIG. 11). Thereby, in the folded state of the stroller 10, the connecting member 50 is connected to the holding member 130 from the rear. In such a stroller 10, the seat 40 can be moved backward and downward by the operation of the holding member 130 deformed from the unfolded state to the folded state to the extent that the connecting member 50 falls backward. (refer to FIG. 11 ). Thereby, the state in which the baby carriage 10 in the folded state stands on its own can be made more stable.

As described above, according to the present embodiment, the stroller 10 is deformable between the unfolded state and the folded state, and includes the stroller body 11 and the seat 40 supported by the stroller body 11 . The stroller body 11 includes a handle 15, a first link member 31 rotatably connected to the handle 15, a rear leg 24 rotatably connected to the first link member 31, and each rotatably connected to the handle 15 and the second link member 32 of the rear leg 24 . Further, the first link member 31 has a detachable and detachable one for holding the seat 40 Holding member 130 .

In the stroller 10 of the present embodiment, the handle 15 can be lowered downward while approaching the rear leg 24 in the deformation from the unfolded state to the folded state. Thereby, the size of the stroller 10 in the folded state can be reduced in size in the front-rear direction and the up-down direction. Moreover, with the operation of the handle 15 in this way, the first link member 31 having the holding member 130 can be tilted rearward, and the seat 40 supported by the first link member 31 can be moved rearward.

A first opening 163b is provided in a region of the accommodating portion 163a where the connecting portion 166 is formed, in a region facing the upper side in the unfolded state of the stroller 110 . In addition, a second opening 163c is provided in a portion of the housing portion 163a where the side surface 167b of the mounting portion 167 is formed.

On the inner surface of the attachment portion 167, a protrusion guide wall 167g extending in the front-rear direction in the unfolded state of the stroller 110, and an action portion guide wall 167h extending in the vertical direction in the unfolded state of the stroller 110 are formed.

The protruding portion 168 is a plate-shaped member. The protruding portion 168 is disposed in the mounting portion 167 so as to face forward and backward in the unfolded state of the stroller 110 It extends in the direction and can move along the protrusion guide wall 167g. The protruding portion 168 is imparted with potential energy toward the second opening portion 163c by the protruding portion imparting potential energy mechanism 168s disposed in the mounting portion 167 . Therefore, when no force is applied to the protruding portion 168, one end 168a of the protruding portion 168 on the side of the second opening portion 163c protrudes toward the outside of the mounting portion 167 through the second opening portion 163c. On the other end 168b (end on the side surface 163d side) of the protruding portion 168, a convex portion 168c that protrudes outward in the width direction and is acted on by the operating device 169 is formed.

The potential energy mechanism 169s is given to maintain the position shown in FIG. 17A. At this time, since the acting portion 169a does not act on the protruding portion 168, the protruding portion 168 also maintains the position shown in FIG. 17A because the protruding portion imparts the potential energy mechanism 168s. Therefore, one end 168a of the protruding portion 168 protrudes from the mounting portion 167 through the second opening portion 163c. On the other hand, when force is applied to the operation button 169b and the action portion 169a is pushed down from the position shown in FIG. 17A to the position shown in FIG. 17B , the inclined surface 169h descends. As a result, the working surface 168d of the protruding portion 168 is pressed in a direction away from the second opening portion 163c, and one end 168a of the protruding portion 168 is retracted into the mounting portion 167 . In other words, the vertical linear motion of the action portion 169 a is converted into the longitudinal linear motion of the protruding portion 168 . Thereby, the engagement between the protruding portion 168 of the connection member 163 and the engagement hole 133 of the holding member 130 can be released by operating the operation button 169b of the action portion 169a.

As described above, when the handle 15 descends downward while approaching the rear leg 24 during the deformation of the stroller 110 from the unfolded state to the folded state, the first link body portion 31a falls backward. At this time, the holding member 130 fixed to the first link body portion 31a also falls backward together, and the connecting member 163 connected to the holding member 130 also rotates together with the holding member 130 in the clockwise direction in FIG. 18 . move and fall backwards.
