The stroller main body 11 is configured to be deformable between the unfolded state and the unfolded state so as to be widely spread (for example, JP 2005-082082 A and JP 2006-117012 A), and the unfolded state shown in FIGS. It can be folded from the state to the folded state shown in FIG. 11 and can be deployed from the folded state to the deployed state. The stroller main body 11 includes a handle 15, and the operator (a guardian) grips the handle 15 from the back side of the baby to steer the stroller 10, and the baby is directed forward in the traveling direction. It is possible to run.

In the present specification, the terms “front”, “rear”, “upper”, “lower”, “back and forth”, and “up and down” with respect to the stroller 10 and the stroller main body 11 are not particularly indicated. The terms “front”, “rear”, “upper”, “lower”, “front-rear direction”, and “vertical direction” mean the operator operating the stroller 10 in the unfolded state. More specifically, the “front-rear direction” of the stroller 10 is a direction connecting the lower left and the upper right of the sheet of FIG. 1 and corresponds to the left and right of the sheet of FIG. And "front" is the side to which the operator who steers the baby carriage 10 faces, unless otherwise instructed, and the lower left side of the paper surface in Fig. 1 and the left side of the paper surface in Fig. 2 become the front side of the baby carriage 10. On the other hand, the “vertical direction” of the stroller 10 is a direction orthogonal to the front-rear direction and orthogonal to the ground contact surface (traveling surface) S. Therefore, when the ground plane is a horizontal plane, the "vertical direction" refers to the vertical direction. Further, the “width direction” or the “vehicle width direction” is a lateral direction, and is a direction orthogonal to any of the “front-rear direction” and the “vertical direction”. Furthermore, “right” and “left” also mean “right” and “left” in the lateral direction or width direction with respect to the operator who steers the stroller 10, respectively.

Further, in the present specification, the terms “upper”, “lower”, and “vertical direction” with respect to the stroller 10 in a folded state and the stroller main body 11 contact the front wheel and the rear wheel of the stroller 10 unless otherwise indicated. It means "upper", "lower", and "vertical direction" based on the state of standing (self-standing state). Further, the terms “width direction”, “vehicle width direction”, “right” and “left” with respect to the stroller 10 in a folded state and the stroller main body 11 “width direction in the stroller 10 in the unfolded state unless otherwise indicated. Means the direction and the side corresponding to “vehicle width direction”, “right” and “left”. Further, the term "longitudinal direction" with respect to the stroller 10 and the stroller main body 11 in the folded state is a direction perpendicular to both the "vertical direction" and the "width direction" and corresponds to the left and right direction of the sheet of FIG. Do. Then, unless specified otherwise, “front” is the side on which the front legs 22 described later are located, and the left side of the paper surface in FIG. 11 is the front side of the stroller 10. Further, “rear” is the side on which the steering wheel 15 is positioned, and the right side of the paper surface in FIG. 11 is the rear side of the stroller 10.

A rear wheel 26 is provided at the lower end of the rear leg 24. In addition, the stroller main body 11 supports a seat 40 disposed between the pair of front leg sides 23 a and between the pair of rear legs 24. In the illustrated example, the baby carriage 10 is configured as a four-wheeled vehicle having two front wheels 25a and two rear wheels 26, but the invention is not limited thereto. For example, one front wheel 25a and two rear wheels 26 may be used. And may be configured as a tricycle.

As shown in FIG. 1, in the present embodiment, the handle 15 includes a pair of handle side portions 15a disposed on the left and right, and a handle intermediate portion 15b connecting between the pair of handle side portions 15a, It has a substantially U-shaped shape as a whole. The lower end portion of the handle 15 is engaged with an engagement member 17 provided on an intermediate portion of the rear leg 24 in the baby carriage 10 in the deployed state. Thus, relative rotation between the handle 15 and the rear leg 24 is restrained.

The handle 15 includes an operation member 18 slidably provided on the handle side 15a, and a remote control device 18a provided on the handle intermediate portion 15b and capable of remotely controlling the sliding of the operation member 18. Have. The operating member 18 is biased downward (toward the end of the U-shape) by a spring (not shown) provided in the handle side 15a. The operation member 18 has a convex portion 18 b that protrudes toward the second link member 32 in the width direction of the stroller 10. The convex portion 18 b cooperates with a locking member 19 described later to hold the stroller 10 in the unfolded state or the folded state.

As shown in FIGS. 1 to 4, the pair of first link members 31 is rotatably (swayably) connected to an intermediate portion of the handle side portion 15 a disposed on the corresponding side (left side or right side) ing. As shown in FIGS. 3 and 4, the first link member 31 has a first link main body 31 a connected to the handle side 15 a and a holding member 130 for holding the seat 40. The first link main portion 31 a is connected to the handle side portion 15 a via a shaft member 81 extending in the width direction of the stroller 10 at the rear portion thereof. Although the 1st link main-body part 31a is a straight rod-shaped member in the example of illustration, it is not restricted to this. Various shapes can be given to the 1st link main-body part 31a. For example, as in the conventional armrest, the first link main body 31a has a pair of side walls and an upper wall connecting the pair of side walls, and opens downward as a whole on the handle side. The connection portion of the portion 15a with the first link main portion 31a and the rear leg 24 described later may be connected from below. Thereby, the design freedom can be improved by improving the design freedom of the stroller 10.

As shown in FIG. 5, the holding member 130 extends from the connection portion 131 along the first link main portion 31 a with a connection portion (housing portion) 131 having a bottom portion 131 a and

side walls

131 b, 131 c, 131 d, and 131 e. And a mounting portion 132. As shown in FIGS. 3 and 4, the holding member 130 is fixed to the first link main body 31 a at the mounting portion 132. The holding member 130 is fixed so that the internal space of the connection portion 131 is opened upward in the unfolded state of the stroller 10. The

side walls

131b and 131d facing the front or the rear of the connection portion 131 are provided with engagement holes 133 that engage with the protrusions 53 of the connection member 50 of the seat 40 described later.

As shown in FIGS. 1 to 4, the rear leg 24 has a connection base 24a forming an upper end thereof and a rear leg 24b extending from the connection base 24a. A rear wheel 26 is provided at the lower end of the rear leg 24b.

As shown in FIG. 1, the connection base 24 a is rotatably (rockably) connected to the first link member 31 disposed on the corresponding side (left side or right side). Further, the connection base 24a is rotatably (swingably) connected to the front leg side 23a disposed on the corresponding side (left or right). The rear leg 24 b extends from between the connection position to the first link member 31 in the connection base 24 a and the connection position to the front leg 22. Thus, interference between the rear leg 24b and the first link member 31 can be effectively prevented, and the rear leg 24 and the first link member 31 can be rotated in a large angle range. Then, the rear leg 24 and the first link member 31 can be made to approach. Similarly, interference between the rear leg 24 b and the front leg 22 can be effectively prevented, and the rear leg 24 and the front leg 22 can be pivoted in a large angle range. Then, the rear legs 24 and the front legs 22 can be made to approach. As a result, as shown in FIGS. 11 and 12, the first link member 31, the rear leg 24, and the front leg 22 can be made to approach, and the size of the stroller 10 in the folded state can be reduced.

As shown in FIG. 4, the connection base 24 a has a longitudinal direction Da that is not parallel to the direction Db from which the rear leg 24 b extends. The front portion of the first link main portion 31a is connected to one side portion (rear portion) of the connection base 24a in the longitudinal direction Da via a shaft member 82 extending in the width direction of the stroller 10. Further, an upper end portion of the front leg 22 is connected to the other longitudinal side portion (forward portion) of the connection base 24 a via a shaft member 83 extending in the width direction of the stroller 10.

Since the connection base 24a has the longitudinal direction Da, the interference between the rear leg 24b and the first link member 31 is effectively prevented, and the rotatable range of the rear leg 24 and the first link member 31 is large. can do. In addition, interference between the rear leg 24 b and the front leg 22 can be effectively prevented, and the rotatable range of the rear leg 24 and the front leg 22 can be enlarged. As a result, as shown in FIGS. 11 and 12, the first link member 31, the rear leg 24, and the front leg 22 can be made to approach, and the size of the stroller 10 in the folded state can be reduced. Further, as shown in FIG. 11 and FIG. 12, with the rear leg 24 and the first link member 31 brought close to each other by relative rotation, a gap may be formed between the rear leg 24 and the first link member 31. it can. Similarly, a gap can be formed between the rear leg 24 and the front leg 22 in a state where the rear leg 24 and the front leg 22 are brought close by relative rotation. By forming the gap even after the relative rotation, it is possible to effectively prevent the clothes and the like from being caught between the elements constituting the relative operation along with the folding operation and the unfolding operation.

As shown in FIG. 4, at least a portion 31 aa including the connection position of the first link main body 31 a to the rear leg 24, the connection base 24 a of the rear leg 24, and the connection position of the front leg 22 to the rear leg 24. The portions 22a are linearly arranged. Thereby, the operating force can be smoothly applied from the handle 15 to the front leg 22 via the first link member 31 and the rear leg 24. In addition, the force from the traveling surface S is smoothly transmitted from the front leg 22 to the handle 15 through the rear leg 24 and the first link member 31. Thereby, an appropriate operating force can be applied to the stroller 10 while grasping the state of the traveling surface S, and the maneuverability of the stroller 10 can be effectively improved. In the illustrated example, the portion 31 aa, the connection base 24 a, and the portion 22 a are linearly arranged, but the present invention is not limited thereto.

Although the front leg 22 is connected to the rear leg 24 in the illustrated example, the present invention is not limited to this. For example, the front leg 22 may be rotatably connected to the first link main portion 31 a of the first link member 31.

Next, the second link member 32 will be described. As shown in FIG. 1, the second link member 32 on the left side is rotatably (swayably) connected to the handle side 15a on the left side of the handle 15 and the rear leg 24 on the left side. Similarly, the second link member 32 on the right side is rotatably connected (slidable) to the handle side 15a on the right side of the handle 15 and the rear leg 24 on the right side. As a result, when the stroller 10 is deformed from the deployed state to the folded state, the handlebar 15 can be lowered downward while approaching the rear leg 24. And as shown in FIG. 11, the dimension in the folded state of the stroller 10 can be downsized in the vertical direction.

As shown in FIG. 4, each second link member 32 includes a second link main body 32 a connected to the handle 15 and the rear leg 24. Each second link member 32 also has an extension 32b extending from between the connecting position of the second link body 32a to the handle 15 and the connecting position to the rear leg 24. The extension portion 32 b extends forward in the deployed state of the stroller 10. Each second link main body 32a is, in part, in the lower portion of the handle side 15a (more specifically, between the lower end portion of the handle side 15a and the operation member 18) in the width direction of the stroller 10. It is connected via an extending shaft member 84. In addition, the second link main body 32a is connected to the middle portion of the rear leg 24 through the boss member 85 extending in the width direction of the stroller 10 in the other portions.

The lock member 19 which protrudes toward the handle side 15a is provided in the part connected to the handle side 15a of each 2nd link main-body part 32a. The lock member 19 has a shape in which several portions of a circle centered on the shaft member 84 are cut away when viewed from the width direction of the stroller 10. The lock member 19 is provided with two

recesses

19a and 19b extending in the radial direction of a circle centered on the shaft member 84 at different positions in the circumferential direction. Each

recess

19a, 19b is adapted to receive from below the projection 18b of the operation member 18 sliding along the handle 15 in the unfolded state or the folded state of the stroller 10. That is, as understood from FIGS. 4 and 12, the locking member 19 rotates with the second link member 32 when the stroller 10 is deformed from the unfolded state to the folded state. Therefore, at this time, the attitude of the lock member 19 with respect to the handle 15 changes. In such a locking member 19, the recess 19a is positioned so as to be able to receive the protrusion 18b of the operation member 18 on the handle 15 when the stroller 10 is in the unfolded state (see FIG. 4). ). Also, the recess 19b is positioned so as to be able to receive the protrusion 18b of the operation member 18 on the handle 15 when the stroller 10 is in the folded state (see FIG. 12).

In the unfolded state of the stroller 10, the convex portion 18b of the operation member 18 is received in the concave portion 19a, whereby the lock member 19 engages with the handle 15, and relative rotation between the second link member 32 and the handle 15 is realized. to bound. As a result, the stroller 10 is held in the unfolded state. Further, when the convex portion 18b of the operation member 18 is received in the concave portion 19b in the folded state of the stroller 10, the lock member 19 engages with the handle 15, and the relative link between the second link member 32 and the handle 15 Restrain movement. As a result, the stroller 10 is held in the folded state.

Next, the third link member 33 will be described. As shown in FIG. 1, the left third link member 33 is rotatably connected (slidable) to the left second link member 32 and the left front leg side 23a. Similarly, the third link member 33 on the right side is rotatably (swayably) connected to the second link member 32 on the right side and the front leg side 23a on the right side. As a result, the front leg 22 is pulled toward the handle 15 and the rear leg 24 via the third link member 33 when the stroller 10 is deformed from the deployed state to the folded state. And as shown in FIG. 11 and FIG. 12, the dimension in the folded state of the baby carriage 10 can be miniaturized in the front-rear direction.

Each third link member 33 is connected to the extension 32b of the second link member 32 at a portion (rear portion) thereof via a shaft member 86 extending in the width direction of the stroller 10. Further, each third link member 33 is connected to an intermediate portion of the front leg side portion 23a at another portion (front portion) via a boss member 87 extending in the width direction of the stroller 10. By connecting the third link member 33 to a position between the connecting position of the second link member 32 to the handle 15 and the connecting position to the rear leg 24, the front leg 22 is connected to the front leg 22 in the folded state of the stroller 10. It can be effectively prevented that the held front wheel 25a and the rear wheel 26 held by the rear leg 24 approach too close (see FIG. 11). Thereby, the baby carriage 10 in the folded state can be made more independent and independent. Furthermore, the third link member 33 is connected to the second link member 32 at the above-mentioned extension 32b, whereby the front leg 22 is held by the front wheel 25a and the rear leg 24 in the folded state of the stroller 10. It is possible to effectively prevent the rear wheel 26 from coming too close (see FIG. 11). Thereby, the baby carriage 10 in the folded state can be made more stable and independent.

Although the third link member 33 is connected to the second link member 32 in the illustrated example, the present invention is not limited to this. The third link member 33 may be rotatably connected to the handle 15.

Returning to FIG. 1, the illustrated baby carriage main body 11 has a rear side connecting bar 27 which connects between the pair of rear legs 24 as a component extending in the width direction. Further, a plate member 60 is attached to the front leg frame 23. The plate member 60 can be used as a step or step when riding on the stroller 10. The plate member 60 is disposed so as to be located above the front wheel 25a. Thereby, when using board member 60 as a step or a step board, stability of baby carriage 10 can be secured.

As shown in FIG. 6A, a guard member 28 is detachably provided between the pair of connection members 46. Further, the base of the hood 100 is connected to the connecting member 46. The connecting member 50 is connected to the connecting member 46 from the outside in the width direction of the stroller 10.

As shown in FIG. 1, the fabric 42 has a bottom fabric portion 42 a that forms the bottom of the seat 40. The cloth material 42 has a pair of side cloth portions 42b connected to the bottom cloth portion 42a from both sides in the width direction of the stroller 10 and a pair of front and rear cloths connected to the bottom cloth portion 42a from both sides in the front and rear direction of the stroller 10 And a portion 42c. The pair of front and rear cloth portions 42c is also connected to the pair of side cloth portions 42b from both sides in the front-rear direction of the stroller 10. As shown in FIG. 9, a cushioning sheet 90 is disposed in the area surrounded by the

cloth portions

42a, 42b and 42c of the cloth material 42. The seat 90 has a seat portion 91 located below the buttocks of the baby who got on the stroller 10 and a back portion 92 located behind the back of the baby who got on the stroller 10.

Next, the connection member 50 will be described with reference to FIG. 6A. As shown in FIG. 6A, the connection member 50 has a connection portion (connection main body portion) 51 connected to the connection member 46 of the main frame member 41, and an attachment portion 52 extending from the connection portion 51. The attachment portion 52 extends to the side opposite to the side on which the guard member 28 of the main frame member 41 is provided. As shown in FIG. 2, the attachment portion 52 is received from above by the connection portion (housing portion) 131 of the holding member 130 in the unfolded state of the stroller 10. As shown in FIG. 6A, the attachment portion 52 has a shape corresponding to the connection portion 131 of the holding member 130, and has

side surfaces

52b, 52c, 52d and 52e. The attachment portion 52 has a protrusion 53 on one of the side surfaces 52 b and 52 d facing in the front-rear direction. The protrusion 53 is provided at a position corresponding to the engagement hole 133 of the holding member 130, and engages with the engagement hole 133. Thus, the connection member 50 is stably held by the holding member 130. The projecting portion 53 is accommodated inside the attachment portion 52 by operating the operation device 54 provided in the connection portion 51. Thereby, the engagement with the engagement hole 133 can be released, and the seat 40 can be removed from the holding member 130.

With reference to FIGS. 6B and 6C, the connecting member 50, and in particular the projection 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. FIG. As shown to FIG. 6B, the connection member 50 has the accommodating part 50a which accommodates the protrusion part 53 and the operating device 54. As shown in FIG. The housing portion 50 a constitutes the connection portion 51 and the attachment portion 52. A first opening 50b is provided in a portion that forms the connection portion 51 of the storage portion 50a, in a region facing upward from one side in the front-rear direction (side of the side surface 52b) in the unfolded state of the baby carriage 10. In addition, a second opening 50 c is provided in a portion which makes the side surface 52 b of the mounting portion 52 of the housing portion 50 a.

A protrusion guide wall 52g extending in the front-rear direction in the unfolded state of the baby carriage 10 and an action part guide wall 52h extending in the vertical direction in the unfolded state of the baby carriage 10 are formed on the inner side surface of the attachment portion 52.

The protrusion 53 is a plate-like member. The projecting portion 53 is disposed in the attachment portion 52 so as to extend in the front-rear direction in the deployed state of the stroller 10 and to be movable along the projecting portion guide wall 52g. The protrusion 53 is biased toward the second opening 50 c by a protrusion biasing means 53 s disposed in the mounting portion 52. Therefore, when no force is applied to the protrusion 53, one end 53a of the protrusion 53 on the second opening 50c side protrudes out of the attachment 52 through the second opening 50c. At the other end 53b (end on the side surface 52d) of the protrusion 53, a protrusion 53c is formed which protrudes outward in the width direction of the stroller 10 and on which the operation device 54 acts. The surface of the protrusion 53c facing the second opening 50c forms an action surface 53d on which the operation device 54 acts. In the unfolded state of the stroller 10, the working surface 53d is inclined upward toward the second opening 50c.

The operating device 54 includes an operating lever 54 a and an operating portion 54 b that acts on the projecting portion 53 along with the operation of the operating lever 54 a. The operation lever 54a is rotatably connected at its intermediate portion to a shaft member 54x extending in the width direction of the stroller 10 in the housing portion 50a. One end 54c of the operation lever 54a is exposed to the outside of the connection portion 51 through the first opening 50b. The other end 54 d of the operation lever 54 a is provided with a convex portion 54 e extending outward in the width direction of the stroller 10. In the connection portion 51, an operation lever biasing means 54s is disposed. The operating lever biasing means 54s holds the operating lever 54a in the posture shown in FIG. 6B, specifically, one end 54c of the operating lever 54a is positioned higher than the other end 54d in the unfolded state of the stroller 10. Do.

The action portion 54 b extends substantially in the vertical direction when the stroller 10 is in the unfolded state. The upper end 54f of the action portion 54b is provided with an opening 54g penetrating in the width direction of the stroller 10. The convex portion 54e of the operation lever 54a is inserted into the opening 54g. The upper end 54f of the action portion 54c is swingably connected to the operation lever 54a. The lower half of the working portion 54c extends along the working portion guide wall 52h and moves along the working portion guide wall 52h. The lower end 54i of the action portion 54c is provided with an inclined surface 54h which is inclined corresponding to the action surface 53d of the protrusion 53. The inclined surface 54h is inclined upward toward the second opening 50c in the unfolded state of the stroller 10.

When no force is applied to the operating lever 54a, the operating lever 54a is maintained at the position shown in FIG. 6B by the operating lever biasing means 54s, whereby the operating portion 54b is also maintained in the position shown in FIG. 6B. In this case, since the action part 54b does not act on the protrusion 53, the protrusion 53 is also maintained at the position shown in FIG. 6B by the protrusion biasing means 53s. Therefore, one end 53a of the protrusion 53 protrudes from the attachment portion 52 through the second opening 50c. On the other hand, when a force is applied to the operation lever 54a and the operation lever 54a rotates from the position shown in FIG. 6B to the position shown in FIG. 6C, the action portion 54b connected to the other end 54d of the operation lever 54a rises and inclines Face 54h rises. As a result, the action surface 53 d of the protrusion 53 is pushed in the direction away from the second opening 50 c, and the one end 53 a of the protrusion 53 is retracted into the mounting portion 52. In other words, in the unfolded state of the stroller 10, the rotational movement of the operation lever 54a is converted into the vertical linear movement of the action portion 54b, and further converted into the longitudinal linear movement of the projection 53. Thus, by operating the operation lever 54a, the engagement between the projection 53 of the connection member 50 and the engagement hole 133 of the holding member 130 can be released.

The seat 40 can be connected to the holding member 130 even when the front and rear direction is reversed. Thus, in FIG. 1 the seat 40 is connected to the holding member 130 with the head frame element 44 arranged on the side of the handle 15 but the foot frame element 45 is arranged on the side of the handle 15 It is connectable to the holding member 130 also in the state.

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

The connection structure between the connecting member 46 and the connecting portion 51 will be described with reference to FIGS. 7 and 8. FIG. 7 shows a connection portion of the connection member 46 with the connection portion 51. Further, FIG. 8 shows a connecting portion of the connecting member 50 with the connecting member 46. As shown in FIG. 7, a fitting member 49 fitted in the inner peripheral surface of the connecting member 46 is fitted in the connecting member 46. The fitting member 49 has a gear shape in a side view, and has an uneven structure on the outer peripheral surface thereof. Eighteen protrusions are provided on the outer peripheral surface of the fitting member 49 at intervals of a central angle of 20 ° on one circumference centered on the rotation axis As. And the connection member 46 has an uneven | corrugated structure corresponding to the uneven structure of the outer peripheral surface of the fitting member 49 in the inner peripheral surface. As shown in FIG. 8, the connection portion 51 also has an uneven structure corresponding to the uneven structure of the outer peripheral surface of the fitting member 49 on the inner peripheral surface thereof. The fitting member 49 is also fitted to the connection portion 51 of the connection 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 (outside). Thus, the connection member 46 is restrained with respect to the connection portion 51.

In the connecting member 46, a pressing member (not shown) for pressing the fitting member 49 into the connecting portion 51 is provided. The pressing member is operated by operating the operating portion 48 to push the fitting member 49 into the connecting portion 51. Thereby, the fitted state of the connection member 46 and the fitting member 49 is released. Then, the restraint on the connection portion 51 of the connection member 46 is released, and the connection member 46 can be rotated with respect to the connection member 50.

Here, the fitting member 49 is biased toward the connecting member 46. In addition, since the concavo-convex structure of the fitting member 49 is point-symmetrical about the rotation axis As, the connecting member 46 has a specific angle (eg, 20 °, 40 ° in the illustrated example) around the rotation axis As. When it is rotated by 60 °, the position of the unevenness on the inner peripheral surface of the connecting member 46 is a position corresponding to the unevenness on the outer peripheral surface of the fitting member 49 (a position where it can be fitted with the fitting member 49) . Therefore, in this case, when the operation by the operation unit 48 is finished, the fitting member 49 moves to the connecting member 46 side, and engages with both the connecting member 46 and the connecting portion 51 again. Thereby, relative rotation of the connection member 46 and the connection part 51 is restrained.

By the way, when the main frame member 41 is rotated with respect to the connecting member 50, not only the back portion 92 of the seat 90 but also the seat portion 91 becomes oblique to the traveling surface S. Therefore, the seat 40 further includes a seat angle adjustment device 70 for adjusting the angle of the seat 91 of the seat 90 with respect to the traveling surface S. 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 set to a desired angle (for example, horizontal).

Specifically, as shown in FIGS. 1 and 9, the seat angle adjustment device 70 has a first string member 71 and a second string member 72. As shown in FIG. 1, one end portion of the first cord member 71 is fixed to the frame side 45 a on one side (left side) of the foot side frame element 45. The first cord 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 side cloth portion 42b on the other side (right side). . 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, a first string member guiding member 74 is fixed to the frame side 45 a on the other side (right side) of the foot side frame element 45. The first cord members 71 extending from the inside of the cloth material 42 pass through the cord through holes of the first cord member guiding device 74. At the other end of the first cord member 71, a first connector 71a for connecting to a second cord member 72 described later is provided. By pulling the other end portion of the first cord member 71, as shown in FIG. 10, the bottom cloth portion of the cloth material 42 can be pushed up from below. Thus, the angle of the seat portion 91 with respect to the traveling surface S can be changed. One end portion of the second strap member 72 is fixed to the other side (right side) frame side portion 44 a of the head-side frame element 44. The second strap member 72 extends out of the cloth material 42. Here, a second string member guiding tool 75 is fixed to the frame side portion 44 a on the other side (right side) of the head side frame element 44. The second cord member 72 extending out of the cloth material 42 passes through the cord through hole of the second cord member guide 75. At the other end 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 string member 71 is sufficiently short as compared to the first string member 71. Therefore, when the other end portion of the first cord member 71 and the other end portion of the second cord member 72 are connected by the

connectors

71 a and 72 a, the first cord member 71 is pulled and the bottom cloth portion 42 a of the cloth 42 is Is kept pushed up from below (see FIG. 10). Even if the seat 40 is turned to be inclined with respect to the travel surface S by the seat angle adjustment device 70 as described above, the seat portion 91 is made a desired angle (for example, horizontal) with respect to the travel surface S be able to.

The adjusting device 70 also has a third string member 73 for further adjusting the angle of the back 92 (reclining angle). As shown in FIGS. 1 and 9, one end portion of the third cord member 73 is fixed to the frame side portion 44 a on one side (left side) of the head-side frame element 44. The third cord 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 side cloth portion 42b on the other side (right side). . The other end portion of the third cord 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 73 a is provided at an intermediate portion of the third string member 73. The adjuster 73a can adjust the length from one end of the third string member 73 to the adjuster 73a and the length from the other end of the third string member 73 to the adjuster 73a. As shown in FIG. 10, the length from the one end portion of the third string member 73 to the adjusting tool 73a and the length from the other end portion of the third string member 73 to the adjusting member 73a are shortened. The bottom fabric portion 42a of the material 42 can be pushed up from below. Thereby, the angle of the back 92 of the seat 90 can be further changed.

The stroller 10 (the stroller main body 11) having the entire configuration as described above can be folded by rotating the respective constituent members in the following manner.

First, in the baby carriage 10 in the unfolded state, the convex portion 18 b of the operation member 18 is received in one concave portion 19 a of the lock member 19. Thereby, relative rotation between the second link member 32 and the handle 15 is restrained. Therefore, by operating the remote control device 18a, the engagement between the second link member 32 and the handle 15 via the lock member 19 is released. Specifically, the operating member 18 is moved upward by the remote control device 18a. Thereby, the fixation of the second link member 32 to the handle 15 and the fixation of the second link member 32 to other components are released. At this time, the lower end portion of the handle 15 is engaged with the engagement member 17 provided at the middle portion of the rear leg 24.

From this state, the handle 15 disposed at the rear position is once pulled back upward, and the engagement of the lower end portion of the handle 15 with the rear leg 24 is released. Thereafter, the handle 15 is pushed downward. At this time, the first link member 31 rotates in the clockwise direction in FIGS. 2 and 4 with respect to the rear leg 24. As a result, the handle 15 and the rear leg 24 approach each other (see FIGS. 11 and 12). In addition, when the handle 15 is pushed downward, the second link member 32 operates with the handle 15. Thus, the second link member 32 pivots in the clockwise direction 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 rearward, the front leg 22 is pulled toward the rear leg 24 while rotating in the counterclockwise direction in FIGS. 2 and 4 with respect to the rear leg 24 (FIGS. 11 and 12) reference). Thus, as shown in FIGS. 11 and 12, the size of the stroller 10 in the front-rear direction is reduced. At this time, as described above, the arrangement position of the handle 15 can be lowered. As a result, not only the dimension in the front-rear direction of the stroller 10, but also the dimension in the vertical direction of the stroller 10 can be reduced.

On the other hand, in order to unfold the stroller 10 (the stroller main body 11) from the folded state, an operation reverse to the above-described folding operation may be performed.

By the way, as described above, in the deformation of the stroller 10 from the unfolded state to the folded state, when the handle 15 is lowered while approaching the rear leg 24, the first link main body portion 31a is inclined backward. At this time, the holding member 130 fixed to the first link main body 31a is also tilted backward, and the connecting member 50 connected to the holding member 130 is also rotated clockwise in FIGS. 2 and 4 together with the holding member 130. Move and lean backwards. As a result, the seat 40 (particularly, the main frame member 41) moves rearward by the amount of rearward inclination of the connecting member 50. Thus, even in the folded state, the baby carriage main body 11 can stably support the seat 40, and the folded baby carriage 10 can be made to 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. (See FIG. 11). In such a baby carriage 10, the independence of the baby carriage 10 in the folded state can be made more stable. 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 the front end portion of the front wheel 25a and the rear wheel 26 in the front-rear direction. (See FIG. 11). In such a baby carriage 10, the independence of the baby carriage 10 in the folded state can be made more stable.

The seat 40 also includes a connecting member 50 that 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, the holding member 130 and the connecting member 50 tilt rearward as the first link main body portion 31a tilts rearward in the deformation from the unfolded state of the stroller 10 to the folded state (see FIG. 11). Thus, 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 an amount corresponding to the rearward inclination of the connection member 50 by the operation of the holding member 130 accompanying the deformation from the deployed state to the folded state. (See FIG. 11). Thereby, the independence of the baby carriage 10 in the folded state can be made more stable.

As described above, according to the present embodiment, the baby carriage 10 is the baby carriage 10 that can be deformed between the unfolded state and the folded state, and the baby carriage main body 11 and the seat 40 supported by the baby carriage main body 11 And. The stroller main 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, a handle 15, and a rear leg 24 respectively. And a second link member 32 connected rotatably. The first link member 31 has a holding member 130 for holding the seat 40 in a removable manner.

In the baby carriage 10 according to this 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. As a result, the dimensions of the stroller 10 in the folded state can be reduced in the front-rear direction and in the vertical direction. Further, along with the operation of the handle 15, the first link member 31 having the holding member 130 can be tilted backward, and the seat 40 supported on the first link member 31 can be moved backward. As a result, the baby carriage main body 11 can stably support the seat 40 even in the folded state, and the folded baby carriage 10 can be made to stand on its own.

Further, according to the present embodiment, the seat 40 has the connecting member 50 that is detachably connected to the holding member 130. Then, in the unfolded state, the connecting member 50 is connected to the holding member 130 from above, and in the folded state, the connecting member 50 is connected to the holding member 130 from the rear. In such a baby carriage 10, the seat 40 can be moved backward and downward by the operation of the first link member 31 accompanied by the deformation from the unfolded state to the folded state. Thereby, the independence of the baby carriage 10 in the folded state can be made more stable.

Further, according to the present embodiment, the front leg 22 rotatably connected to the rear leg 24 or the first link member 31, and the front leg 22 and the handle 15 or the second link member 32 are rotatably connected. And a third link member 33. In such a stroller 10, the front leg 22 can be pulled through the third link member 33 so as to approach the rear leg 24 and the handle 15 at the time of deformation from the deployed state to the folded state. Thereby, the dimension in the folded state of the stroller 10 can be reduced in the front-rear direction.

Further, according to the present embodiment, the third link member 33 is connected to a position between the connection position to the handle 15 in the second link member 32 and the connection position to the rear leg 24. In such a baby carriage 10, in the folded state, it is possible to effectively prevent the front wheel 25a held by the front leg 22 and the rear wheel 26 held by the rear leg 24 from approaching too much. Thereby, the baby carriage 10 in the folded state can be made more independent and independent.

Further, according to the present embodiment, the second link member 32 has the second link main body 32a connected to the handle 15 and the rear leg 24, and the connecting position of the second link main body 32a to the handle 15 and the rear leg And an extending portion 32b extending forward from the connecting position to the extended position in the deployed state. And the 3rd link member 33 is connected to the 2nd link member 32 in extension part 32b. In such a stroller 10, it is possible to effectively prevent the front wheel 25a holding the front leg 22 and the rear wheel 26 held by the rear leg 24 from coming too close in the folded state. Thereby, the baby carriage 10 in the folded state can be made more stable and independent.

Further, according to the present embodiment, the seat 40 has the main frame member 41, the cloth material 42 mounted on the main frame member 41, and the connection member 50 connected to the main frame member 41. . The connecting member 50 is detachably connected to the holding member 130. In the folded state, the connection position between the connection member 50 and the main frame member 41 is located between the rear leg 24 and the handle 15. In such a baby carriage 10, the independence of the baby carriage 10 in the folded state can be made more stable.

Further, according to the present embodiment, the seat 40 has the main frame member 41, the cloth material 42 mounted on the main frame member 41, and the connection member 50 connected to the main frame member 41. . The connecting member 50 is detachably connected to the holding member 130. Then, in the folded state, the connection position between the connection member 50 and the main frame member 41 is located between the front wheel 25 a and the rear wheel 26 in the front-rear direction. In such a baby carriage 10, the independence of the baby carriage 10 in the folded state can be made more stable.

The stroller 10 according to the present embodiment is a stroller 10 that can be deformed between the unfolded state and the folded state, and is removably supported by the stroller main body 11 including the front wheel 25a and the rear wheel 26 and the stroller main body 11 And the seat 40 is attached to the stroller main body 11 and can stand in a folded state.

In the baby carriage 10 according to this embodiment, when the baby carriage 10 is folded, it is possible to avoid the complicated work of removing the seat 40 from the baby carriage main body 11. Moreover, there is no need to store the baby carriage body 11 and the seat 40 separately, which is excellent in handleability. Furthermore, the storage space can be reduced because the folded baby carriage 10 can stand on its own with the seat 40 attached.

<Modification>
Next, a modification of the present invention will be described with reference to FIGS. The modifications described with reference to FIGS. 13 to 18 differ from the above-described embodiment mainly in the following points. That is, the seat 140 includes a child seat 150 and an adapter 160 for detachably connecting the child seat 150 to the baby carriage body 11. However, other configurations can be configured in the same manner as the above-described embodiment.

Further, as shown in FIG. 14, each side portion 156 of the seat portion 152 is provided with an engagement convex portion 159 which protrudes outward in the width direction of the seat portion 152 and engages with the adapter 160 at the center in the longitudinal direction. It is done. The engagement convex portion 159 is designed to be retracted to the inside of each side portion 156 by operating an operation device (not shown). Thereby, the engagement between the child seat 150 and the adapter 160 (more specifically, the engagement between the engaging projection 159 and the engaging recess 164 of the adapter 160 described later) can be released, and the child seat 150 can be It can be removed from the adapter 160.

Next, the adapter 160 will be described with reference to FIGS. 15 to 17B. The adapter 160 detachably connects the child seat 150 and the baby carriage body 11. As used herein, the terms "front", "rear", "horizontal", "upper", "lower", "back and forth", and "up and down" as used with respect to adapter 160 and its components are: Unless otherwise instructed, “front”, “rear”, “horizontal”, “upper”, “lower”, “front and back” based on the operator operating the stroller main body 11 in the deployed state in which the adapter 160 is attached. It means "direction" and "vertical direction". More specifically, the “front-rear direction” of the adapter 160 corresponds to the left and right direction of the sheet of FIG. 15 and connects the lower left and upper right of the sheet of FIG. The “front-rear direction” also corresponds to the “front-rear direction” or the “traveling direction” of the stroller 110 in the illustrated example. And "front" is the side to which the operator who steers the stroller main body 11 to which the adapter 160 is attached is directed, unless otherwise instructed, and the left side of the paper surface in FIG. 15 and the lower left side of the paper surface in FIG. It is the front side of 160. On the other hand, the “vertical direction” of the adapter 160 is a direction orthogonal to the front-rear direction and orthogonal to the ground contact surface (running surface) S. Therefore, when the ground plane is a horizontal plane, the "vertical direction" refers to the vertical direction. Further, the “width direction” is a lateral direction, and is a direction orthogonal to any of the “front-rear direction” and the “vertical direction”.

As shown in FIG. 16, the adapter 160 includes a pair of side support portions 161, a connecting portion 162 connecting the pair of side support portions 161, and a pair of side support portions 161 connected from the outside in the width direction.

When the adapter 160 is attached to the child seat 150, the side support part 161 is disposed outside the child seat 150 in the width direction to face the side part 156 of the seat part 152. In addition, the connection portion 162 is disposed below the child seat 150. An engagement recess 164 is provided on the side of each side support portion 161 facing the side portion 156. The engagement recess 164 engages with the engagement projection 159 of the child seat 150 when the adapter 160 is attached to the child seat 150.

The connection member 163 has a connection portion (connection main body portion) 166 connected to the side support portion 161, and an attachment portion 167 extending downward from the connection portion 166. The attachment portion 167 is accommodated from above in the connection portion 131 of the holding member 130 when the adapter 160 is connected to the baby carriage main body 11 in the unfolded state. The attachment portion 167 has a shape corresponding to the connection portion (housing portion) 131 of the holding member 130, and has

side surfaces

167b, 167c, 167d, and 167e. The mounting portion 167 has a protrusion 168 on the side surface 167 b facing the front. The protrusion 168 is provided at a position corresponding to the engagement hole 133 of the holding member 130, and engages with the engagement hole 133. Thus, the connection member 163 is stably held by the holding member 130. The projecting portion 168 is accommodated inside the attachment portion 167 by operating the operation device 169 provided in the connection portion 166. As a result, the engagement between the holding member 130 and the engagement hole 133 can be released, and the adapter 160, and thus the seat 140 consisting of the adapter 160 and the child seat 150, can be removed from the holding member 130.

With reference to FIGS. 17A and 17B, the connection member 163, and in particular the projection 168 and the operating device 169, will be described in more detail. As shown in FIG. 17A, the connection member 163 has a housing portion 163a for housing the projecting portion 168 and the operation device 169. The housing portion 163 a constitutes the connection portion 166 and the attachment portion 167. A first opening 163 b is provided in a portion of the housing portion 163 a forming the connection portion 166 in a region facing upward in the unfolded state of the baby carriage 110. In addition, a second opening 163 c is provided in a portion forming the side surface 167 b of the attachment portion 167 of the housing portion 163 a.

A protrusion guide wall 167g extending in the front-rear direction in the unfolded state of the baby carriage 110 and an action part guide wall 167h extending in the up-down direction in the unfolded state of the baby carriage 110 are formed on the inner side surface of the attachment portion 167.

The protrusion 168 is a plate-like member. The protruding portion 168 is disposed in the mounting portion 167 so as to extend in the front-rear direction in the deployed state of the baby carriage 110 and to be movable along the protruding portion guide wall 167g. The protrusion 168 is biased toward the second opening 163 c by a protrusion biasing means 168 s disposed in the mounting portion 167. Therefore, when no force is applied to the projecting portion 168, the one end 168a of the projecting portion 168 on the second opening 163c side protrudes out of the attaching portion 167 through the second opening 163c. At the other end 168 b (end on the side surface 163 d) of the protrusion 168, a protrusion 168 c is formed which protrudes outward in the width direction and on which the operation device 169 acts. The surface of the convex portion 168c facing the second opening 163c forms an action surface 168d on which the operation device 169 acts. The working surface 168d is inclined upward and to the opposite side of the second opening 163c.

The operating device 169 has an operating portion 169a extending generally in the vertical direction in the unfolded state of the stroller 110, and an operating portion biasing means 169s biasing the operating portion 169a upward. In the state where no force is applied to the action part 169a by the action part 169a being biased by the action part biasing means 169s, the upper end 169b of the action part 169a is connected through the first opening 163b to the connection part 166. Project outside of The upper end 169 b serves as an operation button 169 b for operating the operation device 169. The lower half of the action portion 169a extends along the action guide wall 167h and is adapted to move along the action guide wall 167h. The lower end 169c of the action portion 169a is provided with an inclined surface 169h which is inclined corresponding to the action surface 168d of the protrusion 168. The inclined surface 169h is inclined upward to the opposite side of the second opening 163c.

When no force is applied to the operation button 169b, the operation portion 169a is maintained at the position shown in FIG. 17A by the operation portion urging means 169s. In this case, since the action portion 169a does not act on the protrusion 168, the protrusion 168 is also maintained at the position shown in FIG. 17A by the protrusion biasing means 168s. Therefore, one end 168a of the protrusion 168 protrudes from the attachment portion 167 through the second opening 163c. On the other hand, when a 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 is lowered. As a result, the action surface 168 d of the protrusion 168 is pushed in a direction away from the second opening 163 c, and one end 168 a of the protrusion 168 is retracted into the attachment portion 167. In other words, the vertical linear motion of the action portion 169 a is converted to the longitudinal linear motion of the protrusion 168. Thus, by operating the operation button 169 b of the action portion 169 a, the engagement between the protrusion 168 of the connection member 163 and the engagement hole 133 of the holding member 130 can be released.

By the way, as described above, in the deformation of the baby carriage 110 from the unfolded state to the folded state, when the handle 15 is lowered while approaching the rear leg 24, the first link main body portion 31a is inclined backward. At this time, the holding member 130 fixed to the first link main body 31a is also inclined backward, and the connecting member 163 connected to the holding member 130 is also rotated clockwise in FIG. 18 together with the holding member 130. , Lean backwards. As a result, the seat 140 (in particular, the child seat 150) moves rearward by the amount of rearward inclination of the connection member 163. Thus, even in the folded state, the baby carriage body 11 can stably support the seat 140, and the folded baby carriage 110 can be made to stand on its own.

In addition, the adapter 160 of the seat 140 has a connecting member 163 which is detachably connected to the holding member 130. The connecting member 163 is connected to the holding member 130 from above in the unfolded state of the baby carriage 110 (see FIG. 13), but is connected to the holding member 130 from the rear in the folded state of the baby carriage 110 (see FIG. 18). That is, the holding member 130 and the connection member 163 are inclined rearward as the first link main body portion 31a is inclined rearward when the baby carriage 110 is deformed from the deployed state to the folded state (see FIG. 18). Thus, in the folded state of the stroller 110, the connection member 163 is connected to the holding member 130 from the rear. In such a baby carriage 110, it is possible to move the seat 140 backward and downward by an amount corresponding to the rearward inclination of the connection member 163 by the operation of the holding member 130 accompanying the deformation from the unfolded state to the folded state. (See FIG. 18). Thereby, the independence of the baby carriage 10 in the folded state can be made more stable.

As described above, according to the present modification, the baby carriage 110 is a baby carriage 110 that can be deformed between the unfolded state and the folded state, and the baby carriage main body 11 and the seat 140 supported by the baby carriage main body 11; Is equipped. The stroller main 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, a handle 15, and a rear leg 24 respectively. And a second link member 32 connected rotatably. The seat 140 has an adapter 160 supported by the stroller main body 11 and a child seat 150 supported by the adapter 160. The first link member 31 has a holding member 130 for holding the adapter 160 in a removable manner.

In the baby carriage 110 of the present modified example, the handle 15 can be lowered downward while approaching the rear leg 24 in the deformation from the unfolded state to the folded state. As a result, the dimensions of the stroller 10 in the folded state can be reduced in the front-rear direction and in the vertical direction. Further, with the operation of the handle 15 as described above, the first link member 31 having the holding member 130 can be tilted backward, and the seat 140 supported on the first link member 31 can be moved backward. As a result, the baby carriage main body 11 can stably support the seat 140 even in the folded state, and the folded baby carriage 110 can be made to stand on its own. Such a baby carriage 110 does not have to store the baby carriage main body 11 and the seat 140 (especially, the child seat 150) separately, and is excellent in handleability.

Further, according to the present modification, the adapter 160 includes the connection member 163 which is detachably connected to the holding member 130. Then, in the unfolded state of the baby carriage 110, the connection member 163 is connected to the holding member 130 from above, and in the folded state, the connection member 163 is connected to the holding member 130 from the rear. In such a baby carriage 110, it is possible to move the seat 140 rearward and downward by the operation of the first link member 31 accompanying the deformation from the unfolded state to the folded state. This makes it possible to further stabilize the self-supporting state of the stroller 110 in the folded state.

Further, the stroller 110 according to this modification is a stroller 110 that can be deformed between the unfolded state and the folded state, and is supported by the stroller main body 11 including the front wheel 25a and the rear wheel 26 and the stroller main body 11 in a removable manner. And a seat 140. The seat 140 has an adapter 160 removably supported by the stroller body 11 and a child seat 150 supported by the adapter 160. The baby carriage 110 can stand on its own in the folded state in which the seat 140 is attached to the baby carriage main body 11.

In the baby carriage 110 according to the present embodiment, when the baby carriage 110 is folded, it is possible to avoid the complicated operation of removing the seat 140 (particularly, the child seat 150) from the baby carriage main body 11. In addition, there is no need to separately store the baby carriage body 11 and the seat 140 (particularly, the child seat 150), and the handling is excellent. Furthermore, the storage space can be reduced because the folded baby carriage 110 can stand on its own with the seat 140 (especially the child seat 150) attached.

Although some modifications to the above-described embodiment have been described above, it is of course possible to apply a plurality of modifications in combination as appropriate.
