Moving. The lower end portion 54a of the rear leg engaging member 54 projects from the lower end of the main link member 22 when the state maintaining member 50 is in the regulated position. When the baby carriage 10 is in the deployed state, the lower end portion 54a is housed in a recess provided on the upper surface of the second link support member 16a fixed to the rear leg 16. As a result, the relative rotation between the second link L2 and the rear leg 16 is prevented. Therefore, when the state maintaining member 50 is in the regulated position, the baby carriage 10 is also maintained in the deployed state by the rear leg engaging member 54 and the second link supporting member 16a. On the other hand, all of the rear leg engaging members 54 are housed in the main link member 22 when the state maintaining member 50 is in the release position. As a result, the second link L2 and the rear leg 16 can rotate relative to each other, and the baby carriage 10 can be folded.

Can be maintained at.

The baby carriage main body 11 having the above configuration can change the handle 40 between the first position and the second position by operating the holding body 42 to swing the handle 40 with respect to the main body frame 12. can. Specifically, when the handle 40 is moved from the first position (backward pushing position) to the second position (face-to-face pushing position), the holding body 42 is pulled upward along the longitudinal direction of the shaft portion 41a of the handle body 41. .. When the holding body 42 moves with respect to the handle body 41, the first position holding portion 36 housed in the receiving portion 46a of the holding body 42 comes out of the receiving portion 46a. As a result, the engagement between the handle 40 and the main body frame 12 is released, and the handle 40 can swing with respect to the main body frame 12.

When the handle 40 reaches the vicinity of the second position, the second position holding portion 37 starts contacting the guide surface 47a of the holding body 42. The second position holding portion 37 abuts on the guide surface 47a to push up the holding body 42 upward along the longitudinal direction of the shaft portion 41a. When the handle 40 reaches the second position, the second position holding portion 37 is released from contact with the guide surface 47a. Then, the holding body 42 automatically moves downward along the longitudinal direction of the shaft portion 41a by the urging force from the urging member, and the receiving portion 48a of the holding body 42 covers the second position holding portion 37. .. As a result, the relative swing between the handle 40 and the main body frame 12 is restricted, and the handle 40 is held in the second position.

When swinging the handle 40 from the second position to the first position, almost the same operation as when swinging the handle 40 from the first position to the second position described above is performed. That is, it is only necessary to first pull up the holding body 42 of the handle 40 and then move the handle 40 from the second position to the first position.

Next, the operation member 60 will be described. As shown in FIGS. 6 and 7, the operation member 60 is operably provided on the handle body 41. As shown in FIGS. 6 and 7, the operating member 60 operates the state maintaining member 50 by operating the operating member 60. That is, the operation member 60 is provided with the installation of the state maintenance member 50.

The operation member 60 is provided between the non-operation position shown in FIG. 6 and the operation position shown in FIG. 7 in the longitudinal direction of the portion of the shaft portion 41a of the handle body 41 where the operation member 60 is provided. It is possible to move along. The operating member 60 is urged from the operating position side to the non-operating position side by an urging member (for example, a spring) (for example, a spring) housed in the shaft portion 41a of the handle 40. That is, when no external force is applied, the operating member 60 is positioned at a non-operating position located below the operating position due to the urging force from the urging member. Further, in the illustrated example, the operation member 60 is connected to the remote control device 43 (see FIG. 1) provided in the intermediate portion 41b of the handle 40 by an operation transmission tool (not shown). Then, by operating the remote control device 43, the operation member 60 can be moved from the operation position to the non-operation position.

As shown in FIG. 8, the operation member 60 has an operation base 61 and an operation protrusion 62 protruding from the operation base 61. As shown in FIGS. 6 and 7, the operation base 61 is attached to the shaft portion 41a of the handle body 41. As can be understood from the comparison of FIGS. 6 and 7, the operation base 61 is slidable with respect to the shaft 41a along the longitudinal direction of the shaft 41a of the handle body 41. Further, the operation protrusion 62 extends inward in the width direction from the operation base 61. On the other hand, as shown in FIGS. 6 and 7, the receiving plate 53 of the state maintaining member 50 extends outward in the width direction from the main body 51.

When the handle 40 is located at the first position, as shown in FIG. 6, the operating member 60 faces the receiving plate 53 of the state maintaining member 50 from the lower side along the longitudinal direction of the main link member 22. Then, when the operating member 60 moves from the non-operating position to the operating position, the operating protrusion 62 abuts on the receiving plate 53 from below and pushes up the state maintaining member 50 from the regulated position toward the release position. That is, when the handle 40 is arranged at the first position, the state maintaining member 50 can be moved from the regulated position to the released position by moving the operating member 60 from the non-operating position to the operating position. As a result, the second link L2 can rotate relative to the fourth link L4. When the handle 40 is located at the second position, the operating member 60 and the receiving plate 53 do not face each other in the direction along the longitudinal direction of the main link member 22. Therefore, even if the operating member 60 moves from the non-operating position shown in FIG. 6 to the operating position shown in FIG. 7, the state maintaining member 50 remains in the regulated position shown in FIG.

The baby carriage body 11 having the above configuration can be folded by rotating each component relative to each other. Specifically, first, prior to the folding operation of the baby carriage 10, the handle 40 is arranged at the first position, and the remote control device 43 is further operated to move the operation member 60 from the non-operation position to the operation position. As a result, the state maintaining member 50 moves from the regulated position to the release position, and the engagement between the state maintaining member 50 and the fourth link L4 is released.

In this state, the second link L2 is once pulled up backward and upward using the handle 40, and then lowered to rotate the fourth link L4 clockwise with respect to the rear leg 16 in FIG. With this operation, the first link L2 and the third link L3 rotate clockwise with respect to the second link L2 in FIG. By such an operation, the second link L2 and the front leg 14 are arranged substantially in parallel in the side view, and the position of the swing axis 30x with respect to the main body frame 12 of the handle 40 is lowered. As described above, the baby carriage 10 can be folded. In the folded state of FIG. 4, the dimensions of the baby carriage 10 along the front-rear direction and the up-down direction can be reduced. On the other hand, in order to unfold the baby carriage 10 from the folded state, the procedure opposite to the folding operation described above may be performed.

By the way, when the handle 40 is arranged in the second position (face-to-face push position) in the deployed stroller 10 and the stroller 10 is driven so that the rear leg 16 side of the stroller 10 is in the front in the traveling direction, the rear wheel 19 May hit the step and give a strong impact to the hind legs 16. When a strong impact is applied to the hind legs 16, the state-maintaining member 50 moves upward, the fourth link L4 rotates together with the hind legs 16, and the regulated engaging projection 52 comes out of the regulated engaging recess 29a. There is a risk that it will end up. Then, the baby carriage 10 may be unintentionally folded. Alternatively, even if the baby carriage 10 is not folded, the regulation engaging protrusion 52 comes out of the regulation engaging recess 29a, so that the strength of the main body frame 12 in the deployed state is lowered, or the strength of the main body frame 12 in the unfolded state is lowered, or the handle 40 with respect to the main body frame 12. The position may shift (particularly, the handle 40 moves downward with respect to the main body frame 12), and the operability of the baby carriage 10 using the handle 40 may deteriorate.

In consideration of such a point, in the baby carriage 10 of the present embodiment, when the handle 40 is arranged at the second position (face-to-face push position), the baby carriage 10 in the deployed state is unintentionally folded. In addition, even if the handle 40 is not folded, the strength of the main body frame 12 is prevented from being lowered or the position of the handle 40 with respect to the main body frame 12 is prevented from being displaced. Specifically, the following measures have been taken.

That is, as shown in FIG. 8, the state maintaining member 50 has a frame-side engaging protrusion 55 protruding from the main body 51. The frame-side engaging protrusion 55 protrudes outward in the width direction from the main body 51. The frame-side engaging protrusion 55 has an inner surface 55a facing the axis 30x defined by the shaft member 30 and an outer surface 55b facing the inner surface 55a.

Further, as shown in FIG. 8, the handle 40 has a regulation member 65 provided on the handle main body 41. The regulating member 65 is fixed to the handle body 41 at both ends of the U-shape of the handle 40. The regulation member 65 swings with respect to the main body frame 12 as the handle main body 41 swings with respect to the main body frame 12.

The regulating member 65 has a main body 66 mounted on the handle main body 41, and a handle-side engaging protruding portion 67 protruding inward in the width direction from the main body 66. The main body 66 has a recess 66a that accommodates the operating protrusion 62 when the operating member 60 is located in a non-operating position. The handle-side engaging protrusion 67 has a first portion 68 having a first surface 68a extending along the circumferential direction of a circle centered on the axis 30x, and a second portion 69 connected to the first portion 68.

As can be understood from FIGS. 12 to 14, in the first portion 68, the distance between the first surface 68a and the axis 30x is larger than the distance between the outer surface 55b of the frame-side engaging protrusion 55 and the axis 30x. As such, it is provided. In other words, the first portion 68 is provided at a position on the radial side of the circle centered on the axis 30x with respect to the frame-side engaging protrusion 55. Further, as shown in FIG. 14, when the handle 40 is in the second position, the first portion 68 has a frame-side engaging protrusion 55 when viewed in the direction from the frame-side engaging protrusion 55 toward the axis 30x. It is provided so as to overlap with. In other words, when the handle 40 is in the second position, the first portion 68 faces the frame-side engaging protrusion 55 from the front in the moving direction from the restricted position to the release position of the state maintaining portion 50. As a result, when the handle 40 is in the second position, the movement of the state maintaining unit 50 from the regulated position to the released position is regulated by the regulating member 65. On the other hand, as shown in FIG. 12, when the handle 40 is in the first position, the first portion 68 has a frame-side engaging protrusion when viewed in the direction from the frame-side engaging protrusion 55 toward the axis 30x. It does not overlap with part 55. As a result, when the handle 40 is in the first position, the restricting member 65 does not prevent the state maintaining member 50 from moving from the restricting position to the releasing position. In other words, when the handle 40 is in the first position, the regulating member 65 allows the state maintaining member 50 to move from the restricted position to the release position.

As shown in FIG. 8, the second portion 69 is located at a position that becomes the rear end portion of the first portion 68 in the rotation direction Dr of the regulation member 65 when the handle 40 swings from the first position to the second position. You are connected. The second portion 69 has a radial surface 69a extending radially inward of a circle centered on the axis 30x from the rear end portion of the first portion 68. As shown in FIG. 14, the radial surface 69a faces the frame-side engaging protrusion 55 from the rear in the rotation direction Dr when the handle 40 is in the second position.

The first portion 68 of the restricting member 65 and the frame-side engaging protrusion 55 restrict the movement of the state maintaining member 50 to the release position when the handle 40 is arranged at the second position. Specifically, even if an impact is applied to the rear wheel 19 from the rear and a force for pushing up the state maintaining member 50 from the rear leg 16 to the state maintaining member 50 is applied, the frame side engaging that protrudes from the state maintaining member 50. The protrusion 55 comes into contact with the first portion 68 of the handle-side engaging protrusion 67, thereby preventing the state maintaining member 50 from moving to the release position. This prevents the state-maintaining member 50 from being disengaged from the fourth link L4.

Further, the second portion 69 of the regulating member 65 and the frame-side engaging protrusion 55 regulate the rearward tilting of the second link L2 with respect to the rear leg 16. Specifically, even if an impact is applied to the rear wheel 19 from the rear and a force is applied to the second link L2 from the rear leg 16 to tilt the second link L2 rearward, the frame protrudes from the state maintaining member 50. When the side engaging protrusion 55 abuts on the second portion 69 of the handle side engaging protrusion 67, the second link L2 is prevented from tilting backward. As a result, it is prevented that the regulation engaging protrusion 52 comes out of the regulation engaging recess 29a and the state maintaining member 50 and the fourth link L4 are disengaged from each other.

In the illustrated example, since the regulation member 65 is fixed to the main body frame 12, the state maintenance member 50 and the regulation member 65 are automatically engaged by simply arranging the handle 40 at the second position. It fits.

Further, as can be understood from FIG. 13, in the illustrated example, the frame-side engaging protrusion 55 and the first portion 68 are moved from the first position to the second position of the handle 40 by the handle 40. Before reaching the second position, they start to overlap each other when viewed in the direction from the frame-side engaging protrusion 55 toward the axis 30x. Since the frame-side engaging protrusion 55 and the first portion 68 are provided in this way, the handle 40 is moved from the first position to the second position (or from the second position to the first position). Even if the remote control device 43 is operated (in the middle of the operation), the possibility that the state maintaining member 50 and the fourth link L4 are disengaged is reduced. As a result, the possibility that the baby carriage 10 is unintentionally folded is further effectively reduced.

Further, in the baby carriage 10 of the present embodiment, when the handle 40 is arranged at the second position (face-to-face pushing position), the baby carriage 10 in the unfolded state is not unintentionally folded or folded. However, further measures have been taken to prevent the strength of the main body frame 12 from being lowered and the position of the handle 40 from being displaced with respect to the main body frame 12. Specifically, the following measures have been taken.

First, as shown in FIG. 11, the handle-side second engaging protrusion 70 extends inward in the width direction from the shaft portion 41a of the handle body 41. The second engaging protrusion 70 on the handle side is fixed to the shaft portion 41a. In the illustrated example, the handle-side second engaging protrusion 70 extends from the stopper 41c.

Further, as shown in FIG. 10, the main body frame 12 is provided with a frame-side second engaging protrusion 71 that protrudes outward in the width direction at a position facing the handle 40 at the second position. .. As can be seen from FIG. 14, the frame-side second engaging protrusion 71 is provided so as to face the handle-side second engaging protrusion 70 from below when the handle 40 is in the second position. .. In the illustrated example, the frame-side second engaging protrusion 71 is provided below the second position holding portion 37 of the first link L1.

The movement of the handle 40 with respect to the main body frame 12 (particularly, the main body frame) when the handle is arranged at the second position by the handle-side second engaging protrusion 70 and the link-side second engaging protrusion 71. Downward movement relative to 12) is regulated. That is, even if the state maintaining member 50 and the fourth link L4 are unintentionally disengaged as a result of an impact being applied to the rear wheel 19 from the rear, the second engaging protrusion 70 on the handle side remains on the frame side. 2 It is supported from below by the engaging protrusion 71. This prevents the handle 40 from moving downward with respect to the main body frame 12. As a result, it is possible to prevent the operability of the baby carriage 10 using the handle 40 from being lowered. Further, since the second engaging protrusion 70 on the handle side is supported from below by the second engaging protrusion 71 on the frame side, rotation of the second link L2 pivotally attached to the handle 40 with respect to the rear leg 16 is prevented. , The unintentional folding of the baby carriage 10 and the decrease in the strength of the main body frame 12 in the unfolded state are prevented.

The second engaging protrusion 70 on the handle side and the second engaging protrusion 71 on the frame side are before the handle 40 reaches the second position when the handle 40 is moved from the first position to the second position. The frame-side second engaging protrusion 71 is provided so as to start facing the handle-side second engaging protrusion 70 from below. As a result, the remote control device 43 is operated while the handle 40 is being moved from the first position to the second position (or while being moved from the second position to the first position), and the state maintaining member 50 and the state maintaining member 50 are operated. Even if the engagement with the fourth link L4 is released, the handle 40 is lowered with respect to the main body frame 12 by supporting the second engagement protrusion 70 on the handle side by the second engagement protrusion 71 on the frame side. The risk of moving to is reduced. Further, the possibility that the second link L2 pivotally attached to the handle 40 will rotate with respect to the rear legs 16 is reduced, and there is a risk of unintentional folding of the baby carriage 10 and a decrease in strength of the main body frame 12 in the deployed state. Is reduced.

The baby carriage 10 described above is only an example, and various changes can be made.

For example, in the above-described example, when the handle 40 is arranged at the second position, the frame-side engaging protrusion 55 moves to the handle-side engaging protrusion 67 when moving the state-maintaining member 50 from the restricted position to the release position. It is regulated by contact, but is not limited to this. The movement of the state maintaining member 50 may be restricted by, for example, the regulating member 65 and the state maintaining member 50 being attracted by a magnetic force. In this case, as shown in FIG. 15, magnets 155 and 168 are attached to the state maintaining member 50 and the regulating member 65, respectively, from the width direction (direction along the axis 30x) when the handle 40 is arranged at the second position. It suffices if they are provided so that they overlap each other when viewed.

Further, when the handle 40 is arranged at the second position, the handle 40 is supported downward by the link-side second engaging protrusion 71 with respect to the downward movement of the handle 40 with respect to the main body frame 12. It is regulated by being done, but it is not limited to this. The movement of the handle 40 may be regulated by, for example, the handle 40 and the main body frame 12 being attracted by a magnetic force. In this case, as shown in FIG. 15, magnets 170 and 171 are placed on the handle 40 (stopper 41c in the illustrated example) and the main body frame 12 (armrest 21 in the illustrated example), respectively, and the handle 40 is in the second position. When arranged, they may be provided so as to overlap each other when viewed from the width direction (direction along the axis 30x). In the example shown in FIG. 15, magnets 170 and 171 form a regulating unit that regulates the movement of the handle 40.

In the embodiment described above, the baby carriage 10 is a baby carriage that can be folded from the unfolded state to the folded state, and has a main body frame 12 that can be deformed from the unfolded state to the folded state, and the first position and the second position. It is provided with a handle 40 connected to the main body frame 12 so as to be swingable between them. The main body frame 12 has a state maintaining member 50 that can move between a regulated position where the folding operation of the baby carriage 10 is restricted and a release position where the folding operation of the baby carriage 10 is possible. Further, the handle 40 has a handle main body 41 connected to the main body frame 12 and a restricting member 65 that restricts the movement of the state maintaining member 50 from the restricting position to the release position when it is located at the second position.

According to such a baby carriage 10, when the handle 40 is in the second position, the state maintaining member 50 is prevented from moving from the regulated position to the released position. Therefore, when the handle 40 is in the second position, even if a strong impact is applied to the main body frame 12 and a force is applied to the state maintaining member 50 from the regulated position to the release position, the state maintaining member 50 is in the release position. It is prevented from moving to. Therefore, the possibility that the baby carriage 10 is unintentionally folded is reduced.

Further, in the embodiment described above, the regulation member 65 is fixed to the handle body 41. As a result, the movement of the state maintaining member 50 from the regulated position to the released position can be automatically regulated only by arranging the handle 40 at the second position.

Further, in the embodiment described above, the state maintaining member 50 has a main body portion 51 and a frame-side engaging protruding portion 55 protruding from the main body portion 51. Further, the restricting member 65 has a handle-side engaging protrusion 67 facing the frame-side engaging protrusion 55 from the front in the direction from the restricting position to the release position when the handle 40 is located at the second position. The frame-side engaging protrusion 55 and the handle-side engaging protrusion 67 can regulate the movement of the state-maintaining member 50 when the handle 40 is positioned at the second position.

Further, in the embodiment described above, the handle-side engaging protrusion 67 has a frame-side engaging protrusion from the rear in the direction Dr from the first position to the second position when the handle 40 is located at the second position. It has a portion 69 facing the portion 55. As a result, when a strong impact is applied to the main body frame 12, the main body frame 12 can be supported from the rear in the above-mentioned direction Dr. This reduces the risk of the body frame 12 being unintentionally folded.

Further, in the embodiment described above, the main body frame 12 is connected to the front leg 14 and the rear leg 16, the first link L1 rotatably connected to the front leg 14 and the rear leg 16, and the first link L1. It has a second link L2 that is movably connected and supported by the hind legs 16 in the deployed state. The state maintaining member 50 is supported by the second link L2, and the handle 40 is swingably connected to the second link L2. In the case of such a baby carriage 10, when the baby carriage 10 is driven so that the rear leg 16 side is in front of the traveling direction, a strong impact is applied to the rear leg 16 and the release position is applied to the state maintaining member 50 of the second link L2. The force to go may be given. However, according to the baby carriage 10 of the present embodiment, if the handle 40 is set to the second position, the regulating member 65 restricts the movement of the state maintaining member 50 from the regulated position to the release position, so that the state maintaining member 50 is used. Even if a force toward the release position is applied, the possibility that the state maintaining member 50 moves to the release position is reduced.

Further, in the embodiment described above, the handle 40 has a handle-side second engaging protrusion 70 that protrudes from the handle body 41. Further, the main body frame 12 has a frame-side second engaging protrusion 71 that protrudes from a portion of the main body frame 12 other than the second link L2. Then, the frame-side second engaging protrusion 71 faces the handle-side second engaging protrusion 70 from below when the handle 40 is located at the second position. The movement of the handle 40 with respect to the main body frame 12 (particularly, the main body frame) when the handle is arranged at the second position by the handle-side second engaging protrusion 70 and the link-side second engaging protrusion 71. Downward movement relative to 12) is regulated. That is, even if the state maintaining member 50 and the fourth link L4 are unintentionally disengaged, the handle side second engaging protrusion 70 is supported from below by the frame side second engaging protrusion 71. This prevents the handle 40 from moving downward with respect to the main body frame 12. As a result, the possibility that the handle 40 is displaced with respect to the main body frame 12 and the operability of the baby carriage 10 using the handle 40 is reduced is reduced. Further, since the handle 40 is supported by the link-side second engaging protrusion 71, the rotation of the second link L2 pivotally attached to the handle 40 with respect to the rear leg 16 is prevented, and there is a risk of unintended folding of the baby carriage 10. Further, the risk of a decrease in the strength of the main body frame 12 in the deployed state is reduced.

Further, in the embodiment described above, the baby carriage 10 is a baby carriage that can be folded from the unfolded state to the folded state, and has a main body frame 12 that can be deformed from the unfolded state to the folded state, and the first and second positions. It is provided with a handle 40, which is connected to the main body frame 12 so as to be swingable between the two. The handle 40 has a handle main body 41 connected to the main body frame 12 and a handle side engaging protrusion 70 protruding from the handle main body 41. Further, the main body frame 12 has a frame-side engaging protrusion 71 that faces the handle-side engaging protrusion 70 from below when the handle 40 is located at the second position.

According to such a baby carriage 10, the handle 40 is moved with respect to the main body frame 12 when the handle 40 is arranged at the second position by the handle side engaging protrusion 70 and the link side engaging protrusion 71 (particularly). , Downward movement with respect to the main body frame 12) is restricted. That is, even if the components of the main body frame 12 for maintaining the main body frame 12 are unintentionally disengaged, the handle 40 is prevented from moving downward with respect to the main body frame 12. .. As a result, the possibility that the handle 40 is displaced with respect to the main body frame 12 and the operability of the baby carriage 10 using the handle 40 is reduced is reduced. Further, since the handle 40 is supported by the link-side engaging protrusion 71, even if the engagement between the components is unintentionally released, the main body frame 12 in the unfolded state is unintentionally deformed into the folded state. The risk of this and the risk of a decrease in the strength of the main body frame 12 in the deployed state are reduced. The movement of the handle 40 with respect to the main body frame 12 is automatically regulated only by arranging the handle 40 at the second position.

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