Next, the configuration and operation of the pinch preventing member 70 will be described in detail with reference to FIGS. 1 to 3. Here, FIG. 1 is a partial perspective view showing a baby carriage, FIG. 2 is an exploded perspective view of FIG. 3, and FIG. 3 is a view for explaining the action of the pinch preventing member.

First, the armrest 60 will be described in more 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 opened downward, and an armrest main body 62 composed of an upper portion 63 and two side portions 64 and 64. And a pair of extension protrusions 66 and 66 which protrude rearward from both side portions 64 of the armrest main body 62. As shown in FIG. 4, the armrest main body 62 extends along the front-back direction. The extension protrusion 66 extends from both sides 64 of the armrest main body 62 to both sides of the upper end portion of the connecting lever 30 disposed behind the armrest main body 62. And the extension protrusion 66 is rotatably connected to the connection lever 30 by the pair of extension protrusion 66 and the connection member (connection shaft) 68 which penetrates the upper end part of the connection lever 30. As shown in FIG. It is.

As shown in Figs. 1 to 3, the pinch preventing member 70 has a gap between the connecting lever 30 and the armrest 60, more specifically the connecting lever 30 and the upper part of the armrest body 62. It is comprised so that the space | gap which arises between the rear end 65 of () may be filled. In this embodiment, the pinch preventing member 70 is disposed in the gap between the attachment portion 72 penetrated to the upper end portion of the connecting lever 30 made of a pipe, and the connecting lever 30 and the armrest 60. It has a gap filling part 76.

In particular, as shown in FIG. 3, the attachment portion 72 is provided below the cover portion 73, which functions as a cover that closes the upper side of the connecting lever 30, and is disposed in the connecting lever. It consists of a pair of insertion portions 74. As shown in FIG. 2, each insertion portion 74 is formed with a hole 74a into which the connecting member 68 is inserted. A connecting member 68 connecting the armrest 60 and the connecting lever 30 is inserted into this hole 74a, whereby the pinch preventing member 70 is fixed to the connecting lever 30 through the attachment portion 72. It is supported in a state.

On the other hand, the gap buried portion 76 is draped along the surface of the side facing the armrest main body 62 of the coupling lever 30 from the attachment portion 72 inserted into the upper end portion of the coupling lever 30. The gap buried portion 76 includes an arc-shaped portion 77 having an arc-shaped contour in FIG. 3, which is viewed from a cross section perpendicular to the rotational axis of the armrest 60 and the connecting lever 30. An arc-shaped portion 77 faces the rear end 65 of the upper arm 63 of the armrest main body 63. As shown in FIG. 3, this arc-shaped portion 77 is the armrest main body 62 when the armrest 60 rotates with respect to the coupling lever 30 about the pivot shaft defined by the connecting member 68. ) Has a shape along the movement trajectory of the rear end 65 of the upper portion 63.

It is desirable to have. In this case, the arc-shaped portion 77 has a contour corresponding to the contour along the width direction of the rear end 65 of the armrest main body 62 along the width direction. As shown in Fig. 2, in the present embodiment, the rear end 65 of the armrest main body 62 has a linear outline along the width direction, and the arcuate portion 77 also has a linear shape along the width direction. It has a contour.

Next, the action of the pinch preventing member 70 when the baby carriage 10 is folded from the deployed state (FIG. 6) and when it is deployed from the folded state will be described.

As described above, the armrest 60 rotates with respect to the connecting lever 30 when the baby carriage 10 is folded from the deployed state. On the contrary, the armrest 60 also rotates with respect to the connecting lever 30 when the baby carriage 10 is unfolded from the folded state. 3, when the armrest 60 rotates with respect to the connection lever 30, a clearance gap arises between the armrest 60 and the connection lever 30, and the magnitude | size of this clearance gap is changed. This is a phenomenon due to the rotational shaft of the armrest 60 and the linking lever 30 not being disposed on the surface of the side facing the armrest main body 62 of the linking lever 30. Therefore, in order to firmly connect the armrest 60 and the connection lever 30, the center of the connection lever 30 (the surface on the side facing the armrest main body 62 (front surface) and the opposite surface (back surface)) This phenomenon inevitably occurs when the extension projection 66 of the armrest 60 is connected to the center of the armrest 60).

This gap is formed between the rear end 65 of the upper arm 63 of the armrest body 62 and the surface of the coupling lever 30. And when the armrest 60 is arrange | positioned in the position which the straight line which connects the rotational shaft with respect to the connection lever 30 of the armrest 60, and the rear end 65 orthogonal to the surface of the connection lever 30 is arranged, The size is the largest. And since this clearance gap is exposed toward the person who folds or expands the baby carriage 10, there exists a possibility that clothing or a finger may be caught in this clearance gap.

On the other hand, in this embodiment, the pinch preventing member 70 which fills this gap is supported by the upper end part of the connection lever 30. As shown in FIG. The arc-shaped portion 77 of the gap buried portion 76 disposed between the armrest main body 62 of the pinch preventing member 70 and the connecting lever 30 has a cross section perpendicular to the rotational axis of the armrest 60. When viewed, it has an outline along the movement trajectory of the rear end 65. Therefore, the arc-shaped part 77 is formed so that the clearance gap changed by the movement with respect to the connection lever 30 of the armrest 60 may be formed. For this reason, it is possible to prevent clothing or the like from being caught in the gap generated between the armrest main body 62 of the armrest 60 and the connection lever 30 during the folding operation or the unfolding operation.

As described above, according to the present embodiment, the pinch preventing member 70 supported by the connecting lever 30 and filling the gap between the armrest main body 62 and the connecting lever 30 of the armrest 60 has a stroller 10. ) Is installed. Therefore, clothing or the like can be prevented from being caught in the gap between the armrest main body 62 and the connecting lever 30.

In addition, according to the present embodiment, the pinch preventing member 70 is supported on the upper end portion of the connecting lever 30 made of a pipe material, and the pinch preventing member 70 functions as a cover member of the connecting lever 30. It is. In other words, the pinch preventing member 70 has a function of filling a gap in a cover member which is normally used, and the number of parts does not increase.

In addition, according to this embodiment, the pinch prevention member 70 is being fixed to the connection lever 30 by the connection member (shaft) 68 which connects the armrest 60 and the connection lever 30. As shown in FIG. Therefore, the pinch prevention member 70 can be firmly attached by a simple structure, without increasing the number of parts.

In addition, according to the present embodiment, the pinch preventing member 70 has an arc-shaped portion 77 having an arc-shaped contour at a cross section orthogonal to the rotation axis of the armrest 60 and the connecting lever 30. And this arc-shaped part 77 has the outline along the movement path of the rear end 65 of the armrest main body 62 of the armrest 60 during a rotation. Accordingly, the arc-shaped portion 77 can fill the gap in response to the size change of the gap in the rotation with respect to the connecting lever 30 of the armrest 60. This makes it possible to more securely prevent the pinching of clothes and the like.

In addition, according to the present embodiment, the pinch preventing member 70 includes an attachment portion 72 penetrated by the connection lever 30, an armrest main body 62 of the armrest 60, and a connection lever (from the attachment portion 72). It consists of the gap | filling part 76 which drapes between 30). Therefore, the size of the entire baby carriage, furthermore, the size of the connecting lever 30 and the armrest 60 can be prevented from being jammed without making the size larger than usual.

In addition, in the present embodiment, the pinch preventing member 70 is inserted into the upper end of the connecting lever 30, and also penetrated by the connecting member 68 together with the connecting lever 30 and the armrest 60, thereby connecting. Although the example supported and fixed to the lever 30 was shown, it is not limited to this. As long as it is arranged to fill the gap between the armrest 60 and the connecting lever 30, the pinch preventing member 70 can be supported by various methods. For example, the pinch preventing member 70 and the connecting lever 30 may be fixed only by being inserted into the upper end of the connecting lever 30. Alternatively, as described in detail in the second embodiment, the pinch preventing member 70 is connected to the connecting lever 30 only by being penetrated together with the connecting lever 30 by the connecting member 68 without penetrating the connecting lever 30. 30) may be fixed.

Next, the guide arm 118 of the baby carriage according to the present invention will be described in more detail with reference to FIGS. 16 and 22 to 25.

22 to 25 are views illustrating the guide arm 118 of the baby carriage.

As shown in Figs. 16 and 22, the guide arm 118 of the baby carriage of the present invention extends and is arranged between a pair of armrests 116 of the baby carriage and at the same time a pair of armrests 116 connected to the pair of armrests 116 The intermediate member 185 is provided between the end 180 and the pair of ends 180.

As shown in FIGS. 16, 22, and 23, the intermediate member 185 extends between a pair of armrests 116 and has a spring portion between the core portion 170 and the core portion 170. A pair of soft members 161 which are provided separately and softer than the core portion 170, and a protective member 162 which is installed on the outer surface of each soft member 161 and protects the soft member 161. Have

Among these, the core part 170 is comprised from the polypropylene belt (hard member) 172 and the soft-type resin member 171 arrange | positioned in parallel with the polypropylene belt 172, as shown in FIG. . Among them, the soft resin member 171 is composed of the soft resin member 171a and the soft resin member 171b, and has a two-layer structure.

In addition, as shown in FIG. 23, a detachable outer cloth 163 is provided on the outer surface of the protective member 162.

As shown in FIG. 24, the core portion 170 and the pair of soft members 161 are separated from each other, and the core portion 170 and the soft members 161 are not fixed by an adhesive or the like.

That is, as shown in FIG. 24, each soft member 161 is covered with an outer surface by a protective member 162, and each soft member 161 is provided to the core portion 170 via a protective member 162. Attached.

In this case, each of the soft members 161 is covered by the protective member 162 on the outside thereof, and the protective member 162 is turned inward from the side of the soft member 161. For this reason, the protection member 162 is interposed between the core member 170 and each soft member 161, and spaces 161a and 161a are formed between the soft member 161 and the core member 170. have. In addition, spaces 170a and 170a are formed between both side portions of the core member 170 and the outer fabric 163.

In addition, the core portion 170 and the soft member 161 are not adhered to each other by an adhesive or the like, and the soft member 161 is the core portion 170 through the protection member 162 which is returned to the inside of the soft member 161. Attached in a separated state. For this reason, when the guide arm 118 is moved to the up-down direction (refer FIG. 25), the soft member 161 can slide freely on the core part 170, and excessive burden is applied to the soft member 161. Can be prevented.

In addition, as shown in FIG. 24, the soft member 161 is covered with an outer surface by the protective member 162, and the soft member 161 is attached to the core portion 170 via the protective member 162. have. Thus, since the protective member 162 can be sandwiched by inserting the protective member 162 between the soft member 161 and the core portion 170, the protective member 162 is peeled off from the soft member 161. Can be prevented.

Next, the modification of the guide arm 118 is demonstrated using FIG.

A modification of the guide arm 118 shown in FIG. 26 is a soft system instead of the core portion 170 from the polypropylene belt 172 and the soft resin member 171 disposed in parallel with the polypropylene belt 172. A core portion 170 composed of a pair of polypropylene belts 172 provided with the resin member 171 and the soft resin member 171 therebetween is used. Otherwise, the embodiment shown in FIGS. 22 to 25 is used. Is approximately the same as

In the modified example shown in FIG. 26, the same parts as in the embodiment shown in FIGS. 22 to 25 are denoted by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 26, a pair of polypropylene belts 172 are provided on both surfaces of the soft resin member 171 with the soft resin member 171 therebetween. For this reason, the force applied to the core part 170 can be disperse | distributed to the flexible resin member 171 and each polypropylene belt 172 provided in both surfaces of the flexible resin member 171 in a balanced manner. For this reason, it is possible to reliably prevent the guide arm 118 from deforming from its original shape by repeatedly moving up and down while further improving the durability of the guide arm 118.
