Here, FIG. 1 is a partial perspective view showing the stroller, FIG. 2 is an exploded perspective view of FIG. 3, and FIG. 3 is a view for explaining the operation of the pinching prevention member.

  First, the armrest 60 will be further described in detail with reference to FIGS. 1 to 3. In particular, as shown in FIG. 2, the armrest 60 has a substantially U-shaped cross section that opens downward, and includes an armrest body 62 including an upper portion 63 and both side portions 64, 64, and both side portions 64 of the armrest body 62. And a pair of extending portions 66 and 66 extending rearward from the rear side. As shown in FIG. 4, the armrest body 62 extends along the front-rear direction. The extending portion 66 extends from both side portions 64 of the armrest body 62 to both sides of the upper end portion of the connecting rod 30 disposed behind the armrest body 62. The extending portion 66 is rotatably connected to the connecting rod 30 by a connecting member (connecting shaft) 68 that passes through the pair of extending portions 66 and the upper end portion of the connecting rod 30.

  As shown in FIGS. 1 to 3, the pinching prevention member 70 is formed between the connecting rod 30 and the armrest 60, more specifically, between the connecting rod 30 and the rear end 65 of the upper portion 63 of the armrest body 62. It is comprised so that the gap which arises in may be filled up. In the present embodiment, the pinching prevention member 70 includes a mounting portion 72 fitted into the upper end portion of the connecting rod 30 made of a pipe, and a gap filling portion 76 disposed in a gap between the connecting rod 30 and the armrest 60, have.

  In particular, as shown in FIG. 3, the mounting portion 72 includes a lid portion 73 that functions as a lid that seals the upper side of the connecting rod 30, and a pair of insertions that are provided below the lid portion and disposed in the connecting rod. A portion 74; As shown in FIG. 2, each insertion portion 74 is formed with a hole 74 a into which the connecting member 68 is inserted. By inserting the connecting member 68 that connects the armrest 60 and the connecting rod 30 into the hole 74a, the pinching prevention member 70 is supported in a state of being fixed to the connecting rod 30 via the mounting portion 72. Become.

  On the other hand, the gap filling portion 76 hangs down from the attachment portion 72 fitted into the upper end portion of the connecting rod 30 along the surface of the connecting rod 30 facing the armrest body 62. The gap filling portion 76 includes an arc-shaped portion 77 having an arc-shaped contour in FIG. 3 showing a cross-sectional view orthogonal to the rotation axis of the armrest 60 and the connecting rod 30, and this arc-shaped portion 77 is an upper portion of the armrest main body 63. It faces the rear end 65 of 63. As shown in FIG. 3, the arc-shaped portion 77 has a rear end 65 of the upper portion 63 of the armrest main body 62 when the armrest 60 rotates with respect to the connecting rod 30 around the rotation axis defined by the connecting member 68.

  Next, the action of the pinching prevention member 70 when the stroller 10 is folded from the unfolded state (FIG. 6) and when unfolded from the folded state will be described.

  As described above, the armrest 60 rotates with respect to the connecting rod 30 when the stroller 10 is folded from the unfolded state. Conversely, the armrest 60 also rotates relative to the connecting rod 30 when the stroller 10 is unfolded from the folded state. As shown in FIG. 3, when the armrest 60 rotates with respect to the connecting rod 30, a gap is generated between the armrest 60 and the connecting rod 30, and the size of the gap changes. . This is a phenomenon resulting from the fact that the pivot shafts of the armrest 60 and the connecting rod 30 are not arranged on the surface of the connecting rod 30 facing the armrest main body 62. Therefore, in order to firmly connect the armrest 60 and the connecting rod 30, the center of the connecting rod 30 (the surface on the side facing the armrest main body 62 (front surface) and the opposite surface (rear surface)) This phenomenon inevitably occurs when the extension 66 of the armrest 60 is connected at the center.

  This gap is generated between the rear end 65 of the upper part 63 of the armrest body 62 and the surface of the connecting rod 30. And when the armrest 60 is arrange | positioned in the position where the straight line which connects the rotating shaft with respect to the connection rod 30 of the armrest 60 and the rear end 65 is orthogonal to the surface of the connection rod 30, the magnitude | size of a clearance gap becomes the largest. And since this clearance gap is exposed toward the person who folds or develops the stroller 10, there is a possibility that clothes or fingers may be caught in the clearance.

  On the other hand, in this embodiment, a pinching prevention member 70 that fills this gap is supported by the upper end portion of the connecting rod 30. The arc-shaped portion 77 of the gap filling portion 76 disposed between the armrest main body 62 and the connecting rod 30 of the pinching prevention member 70 follows the movement locus of the rear end 65 in a cross-sectional view orthogonal to the rotation axis of the armrest 60. Has a contour. Therefore, the arc-shaped portion 77 is formed so as to fill a gap that changes due to the movement of the armrest 60 relative to the connecting rod 30. For this reason, it is possible to prevent clothes or the like from being caught in a gap generated between the armrest body 62 of the armrest 60 and the connecting rod 30 during the folding operation or the unfolding operation.

  As described above, according to the present embodiment, the stroller 10 is provided with the pinching prevention member 70 that is supported by the connecting rod 30 and fills the gap between the armrest body 62 of the armrest 60 and the connecting rod 30. Therefore, it is possible to prevent clothing or the like from being caught in the gap between the armrest body 62 and the connecting rod 30.

  According to the present embodiment, the pinching prevention member 70 is supported by the upper end portion of the connecting rod 30 made of a pipe material, and the pinching prevention member 70 also functions as a lid member of the connecting rod 30. Yes. In other words, the pinching prevention member 70 is a normally used lid member having a function of filling a gap, and does not increase the number of parts.

  Further, according to the present embodiment, the pinching prevention member 70 is fixed to the connecting rod 30 by the connecting member (shaft) 68 that connects the armrest 60 and the connecting rod 30. Therefore, the pinching prevention member 70 can be firmly attached with a simple configuration without increasing the number of parts.

  Furthermore, according to the present embodiment, the pinching prevention member 70 has the arc-shaped portion 77 having an arc-shaped contour in a cross section orthogonal to the rotation axis of the armrest 60 and the connecting rod 30. And this arc-shaped part 77 has the outline along the movement path | route of the rear end 65 of the armrest main body 62 of the armrest 60 in rotation. Therefore, the arc-shaped portion 77 can fill the gap corresponding to the change in the size of the gap during the rotation of the armrest 60 relative to the connecting rod 30. Thereby, it is possible to more reliably prevent the clothing from being caught.

  Further, according to the present embodiment, the pinching prevention member 70 includes the mounting portion 72 fitted into the connecting rod 30, and the gap filling portion 76 that hangs down from the mounting portion 72 between the armrest body 62 of the armrest 60 and the connecting rod 30. , Is composed of. Accordingly, it is possible to prevent the clothes and the like from being caught without increasing the overall size of the stroller, and further, the size of the connecting rod 30 and the armrest 60.

  In the present embodiment, the pinching prevention member 70 is fitted into the upper end of the connecting rod 30 and is further penetrated by the connecting member 68 together with the connecting rod 30 and the armrest 60 to be supported and fixed to the connecting rod 30. However, the present invention is not limited to this. As long as it arrange | positions so that the clearance gap between the armrest 60 and the connecting rod 30 may be filled, the pinching prevention member 70 can be supported by various methods. For example, the pinching prevention member 70 and the connecting rod 30 may be fixed only by being fitted to the upper end of the connecting rod 30. Alternatively, as described in detail in the second embodiment, the pinching prevention member 70 is fixed to the connecting rod 30 only by being inserted together with the connecting rod 30 by the connecting member 68 without being fitted into the connecting rod 30.
