Description

  The present invention relates to a folding stroller in which a handle can swing between a first position and a second position, and more particularly to a stroller capable of preventing unintentional swinging of the handle during folding.

  2. Description of the Related Art Conventionally, a stroller for riding an infant so that the infant faces forward in the traveling direction is known. Further, in recent years, for example, as disclosed in Patent Document 1, a first position (facing pressing position) that is inclined forward from the vertical axis in a side view and a second position that is inclined backward from the vertical axis are disclosed. A baby stroller provided with a handle that can swing between the (rear pressing position) is also widely used. In such a stroller, when the handle is in the second position, the operator (guardian) may hold the handle from the back side of the infant and push the stroller so that the infant faces forward in the traveling direction. it can. On the other hand, when the handle is in the first position, the operator grasps the handle from the position of the front leg facing the infant and observes the state of the infant so that the rear leg is in the forward direction of the stroller. Can be pushed forward.

  Most strollers used today are also foldable. As with the stroller disclosed in Patent Document 1, many strollers are configured to be foldable so that the front leg and the handle are close to each other in a side view. Thereby, the dimension in the front-back direction of the folded stroller can be reduced.

The When the handle 50 is fixed at the second position, the handle 50 is inverted from a position (a position indicated by a one-dot chain line in FIG. 2) on the rotation axis (swing center) O1 along the vertical axis in a side view. The stroller 10 is inclined rearward (inclined to the rear leg side) and extends substantially parallel to the frame member 26. The operator can hold the handle 50 from the position of the rear leg side of the stroller 10 on the back side of the infant and push the stroller 10 so that the infant faces forward in the traveling direction. At this time, the front leg side of the stroller 10 is the front in the traveling direction.

  As well shown in FIG. 6, the handle 50 is provided with a regulating projection 53 that projects inward in the width direction from the straight portion 51. On the other hand, the stroller body 20 is provided with restricting members 31a and 31b that come into contact with the restricting protrusion 53 and define a swingable range of the handle 50 with respect to the stroller body 20. As shown in FIG. 6, the first restricting member 31a is disposed in the vicinity of the first engaging portion 30a, and the handle 50 further swings with respect to the stroller body 20 from the second position side beyond the first position. To regulate. on the other hand. The second restricting member 31b is disposed in the vicinity of the second engaging portion 30b, and restricts the handle 50 from further swinging with respect to the stroller body 20 beyond the second position from the first position side. Therefore, in the stroller 10 in the unfolded state, the handle 50 is positioned only in a range between the first position shown in FIG. 3 and the second position shown in FIG.

  Further, the handle 50 includes an operation member 55 slidably provided on the straight portion 51 and a remote operation device 57 provided on the intermediate portion 52 and capable of remotely operating the operation member 55. Yes. The operation member 55 is urged downward (toward the end of the U shape formed by the handle) by a spring (not shown). Then, by operating the remote operation device 57, the operation member 55 can be pulled up against urging by a spring (not shown). When the handle 50 is disposed at the second position in the stroller 10 in the unfolded state as shown in FIG. 6, the operation member 55 on the handle 50 is slidably provided on the frame member 26. It comes in contact with the bottom from below. The frame member 26 incorporates a locking mechanism (not shown) for fixing the frame member 26 to the rear leg 24 and maintaining the stroller 10 (stroller body 20) in the unfolded state. The unlocking member 27 is configured to release a locking mechanism (not shown) that fixes the frame member 26 to the rear leg 24 by sliding upward.

  In addition, the stroller 10 further includes a back frame 70 that is rotatably connected to the stroller body 20. The back frame 70 has a pair of side parts 71 connected to the stroller body 20 so as to be rotatable, and a connecting part 72 that connects the pair of side parts 71. Hinges 70 a and 70 b are formed at the connection points between the side portions 71 and the connecting portions 72. The rotation axis (swing center) of the side portion 71 with respect to the stroller body 20 is the rotation axis (swing center) of the handle 50 with respect to the stroller body 20, the rotation axis between the bracket 34 and the frame member 26, and the frame member. 26 and the rotation axis of the side connecting member 32 coincide with each other.

The seat portion 91 of the seat 90 is supported by the upper connecting bar 36 and the side connecting member 32, and the back portion 92 of the seat 80 is supported by the frame member 26 and the back frame 70. The sheet is indicated by a two-dot chain line in FIGS. 2 and 3 and is omitted in other drawings.

  The stroller 10 (stroller body 20) having the overall configuration as described above can be folded by rotating the respective constituent members with each other as follows.

  When the handle 50 is disposed at the first position, first, the handle 50 is swung with respect to the stroller body 20, and the handle 50 is moved to the second position. When the handle 50 is disposed at the first position and the sliding member 60 on the handle 50 is engaged with the first engagement portion 30a of the stroller body 20, the folding operation of the stroller body 20 is restricted by the handle 50. Because. Therefore, when the handle 50 is disposed at the first position, the sliding member 60 and the first engaging portion 30a are released by pulling up the sliding member 60 on the handle 50. In this state, the handle 50 is swung with respect to the stroller body 20 to move the handle 50 to the second position. Then, the handle 50 is fixed to the stroller body 20 by the engagement between the sliding member 60 on the handle 50 arranged at the second position and the second engaging portion 30b on the frame member 26 of the stroller body 20. At this time, the handle 50 that is swingably connected to the frame member 26 at the lower end thereof is also fixed to the frame member 26 by the engagement of the sliding member 60 and the second engaging portion 30b. Then, during the following folding operation, in a side view (when viewed from the side), the lower portion of the handle 50 performs the same operation as that of the frame member 26.

  Next, by operating the remote control device 57, the fixing of the frame member 26 to the rear leg 24 is released. Specifically, the operation member 55 is operated by the remote operation device 57, and at the same time, the lock release member 27 on the frame member 26 is operated via the operation member 55 to release the fixation to the rear leg 24 of the frame member 26. . In this state, the handle 50 arranged at the second position is once pulled upward and then pushed downward. At this time, the frame member 26 operates together with the handle 50 as described above. As a result, the connecting bracket 34 rotates in the clockwise direction in FIG. 2 with respect to the rear leg 24. In accordance with this operation, the armrest 28 and the side connecting member 32 are rotated clockwise in FIG. 2 with respect to the frame member 26. By such an operation, in a side view (when viewed from the side), the handle 50 moves so as to approach the front leg 22 while maintaining a substantially parallel relationship with the front leg, and the stroller 10 (stroller body in the front-rear direction) is moved. The dimension of 20) is reduced.

  As shown in FIG. 4, when the stroller 10 (stroller body 20) is folded back and forth as described above, the position of the handle 50 is lowered while the handle 50 and the front leg 22 are kept substantially parallel to each other. Be able to. As a result, not only the dimensions in the front-rear direction of the stroller 10 (stroller body 20) but also the vertical dimension of the stroller 10 (stroller body 20) can be reduced.

  In the illustrated stroller, the upper connecting bar 36, the footrest 38, and the rear connecting bar 40 each have a pair of hinges 36a, 36b, 38a, 38b, 40a, 40b spaced apart in the width direction. (See FIGS. 1 and 5). Similarly, the handle 50 also has a pair of hinges 50a and 50b spaced apart along the width direction. Further, the back frame 70 also has a pair of hinges 70a and 70b spaced apart in the width direction. As shown in FIG. 5, when the stroller 10 is folded in the front-rear direction, one of the hinges 36a, 38a, 40a, 50a, 70a of these members 36, 38, 40, 50, 70 is generally the first shaft. Positioned on La, one of the hinges 36b, 38b, 40b, 50b, 70b is positioned approximately on the second axis Lb. As a result, the stroller 10 (stroller body 20) can be folded around the first axis La and the second axis La, respectively, and thereby the size in the width direction can also be reduced.

  On the other hand, in order to unfold the stroller 10 (stroller body 20) from the folded state, an operation reverse to the above-described folding operation may be performed.

  By the way, as shown in FIG. 4, in the state where the stroller body 20 is folded in the front-rear direction, if the sliding member 60 moves from the engagement position to the release position due to a malfunction or the like, the sliding member 60 and the second engagement portion The engagement with 30b is released, and the handle 50 is in a state of being swingable with respect to the stroller body 20. In particular, in the present embodiment, the first restricting member 31a that can come into contact with the restricting protrusion 53 of the handle 50 in the deployed state of the stroller body 20, as shown in FIG. 4, in the state where the stroller body 20 is folded back and forth. It is no longer located at a position greatly deviating from the movement locus T1 of the first restricting projection 53 when the handle is swung. Therefore, assuming that the handle 50 can swing with respect to the stroller body in the folded state, the handle 50 is completely moved to the front leg side beyond the first restricting projection 53 as shown by a two-dot chain line in FIG. It can swing to a position where it falls down. When the stroller body 20 is deployed in this state, the handle 50 cannot be returned to the first position and the second position.

  On the other hand, in this embodiment, in order to prevent this problem, as shown in FIG. 6, a protruding member 80 that protrudes outward in the width direction from the armrest 28 is provided. As shown in FIGS. 6 and 7, the protruding member 80 is engaged with the sliding member 60 when the handle 50 is disposed at the second position and the stroller body 20 is in the unfolded state (the solid line in FIG. 7). ) And a release position (a position indicated by a two-dot chain line in FIG. 7), and is allowed to move between the engagement position and the release position of the slide member 60. It is configured and arranged. On the other hand, the protruding member 80 is disposed in the sliding path between the engagement position and the release position of the sliding member 60 when the handle 50 is disposed at the second position and the stroller body 20 is in the folded state. The sliding member 60 is configured and arranged to restrict movement of the sliding member 60 from the engagement position to the release position. That is, the protruding member 80 does not restrict the swinging of the handle 50 by contacting the handle 50 and its accessories when the sliding member 60 malfunctions, but restricts the operation of the sliding member 60 when folded. This prevents the malfunction of the sliding member 60 itself. Therefore, not the contact between the handle 50 and another member (for example, the first restricting member 31a), but the structural relationship between the sliding member 60 provided on the handle 50 and the protruding member 80 provided on the stroller body 20 The engagement can more reliably prevent the handle 50 from swinging with respect to the stroller body 20 in the folded state. Further, the first restricting member 31a and the second restricting protrusion 31b do not need to contact the handle 50 itself, and the first restricting member 31a and the second restricting protrusion 31b are arranged when the stroller 10 (stroller body 20) is deployed. It is sufficient that even the restricting protrusion 53 protruding inward in the width direction can come into contact. Therefore, it is not necessary to secure a large amount of the first restricting member 31a and the second restricting protrusion 31b projecting outward from the stroller body 20 in the width direction. It is also possible to very effectively suppress clothing and the like from being caught between the handle 50 (the restricting protrusion 53) and the first restricting member 31a during the swinging movement of the member 50.

  Further, according to the present embodiment, the projecting member 80 is opposite to the side to which the front leg 22 and the rear leg 24 are connected in the longitudinal direction of the armrest 28 with the rotation center between the armrest 28 and the frame member 26 interposed therebetween. It is provided at a position on the armrest 28 on the side. That is, the armrest 28 is not connected to the frame member 26 at one end (rear end in the unfolded state), but extends to both sides of a connection point (rotation center) with the frame member 26. A projecting member 80 is provided on the side opposite to the side to which the front leg 22 and the rear leg 24 are connected, with a connection point (rotation center) between the front leg 22 and the rear leg 24. As a specific configuration, as well shown in FIG. 6, the armrest 28 is connected to the front leg 22 and the rear leg 24 beyond the rotation axis (rotation center) O2 between the armrest 28 and the frame member 26. An extending portion 29 that extends to the opposite side of the extending side is provided, and a projecting member projects from the extending portion 29. According to such a configuration, when the handle 50 is disposed at the second position and the stroller body 20 is in the unfolded state, the protruding member 80 is disposed at a position greatly deviated from the sliding path of the sliding member 60. Accordingly, the sliding member 60 can be stably and easily operated in the unfolded state. On the other hand, as shown in FIG. 7, the position facing the sliding member 60 in the sliding direction of the sliding member 60 by the rotation of the armrest 50 in the folding operation with respect to the frame member 26 fixed to the handle 50. It is possible to automatically arrange the protruding member 80 on the surface.

  Further, according to the present embodiment, as well shown in FIG. 6, the protruding member 80 is in the engagement position when the handle 50 is disposed in the second position and the stroller body 20 is in the folded state. A plate-like portion 81 opposed to the sliding member 60, and a rib portion 82 that is connected to the plate-like portion 81 and reinforces the plate-like portion 81. Such a projecting member 80 can sufficiently exhibit the function of restricting the movement of the sliding member 60 by the plate-like portion 81, and is provided with sufficient rigidity by the rib portion 82. 81 can function more effectively, and it is possible to more reliably prevent the sliding member 60 from overcoming the protruding member 80 and malfunctioning.

  Furthermore, according to the present embodiment, the plate-like portion 81 is in a direction substantially orthogonal to the sliding direction of the sliding member 60 when the handle 50 is disposed at the second position and the stroller body 20 is in the folded state. The rib portion 82 extends substantially parallel to the sliding direction of the sliding member 60 when the handle 50 is disposed at the second position and the stroller body 20 is in the folded state. According to such a protruding member 80, it is possible to more reliably prevent the sliding member 60 from overcoming the protruding member 80 and malfunctioning.

  Various modifications can be made to the above-described embodiment within the scope of the present invention. Hereinafter, an example of the change will be described.

  For example, the overall configuration of the stroller 10 described in the above embodiment is merely an example. For example, although the stroller 10 can be folded in the front-rear direction as shown in FIG. 4, it may be configured not to be folded in the width direction as shown in FIG.
