Further, as shown in Fig. 4, the back pad support frame 46, which is formed in a substantially U-shape, is provided at the rear end portion of the side frame 40 so as to be freely swayable with respect to the side frame 40. Moreover, the base 48 is provided in a field surrounded by the side frame 40, the front upper upper stay stay 42 and the back pad support frame 46, and is further fixed to the pair of links on the rear side of the back pad support frame 46. The reclining member 56 is tilted between the rods 30, 30, and by adjusting the length of the reclining member 56, the reclining angle of the back pad holder 46 can be adjusted.

However, as clearly shown in FIG. 6, the locking member 32 that engages with the end portion of the bracket 38 in the unfolded state and maintains the unfolded state is disposed at a lower portion of each of the connecting rods 30 so as to be movable along the connecting rod 30. The long direction slides freely. As shown in FIGS. 4 and 6, each of the lock members 32 has an actuating plate 34 that protrudes outward, and on the other hand, as shown in FIG. 4, an unlocking member 22 is provided at a lower portion of the pusher 20, and The unlocking member 22 has an unlocking lever 24 that engages with the actuating plate 34 of the locking member 32. The unlocking member 22 is slidable upward along the hand push rod 20 by operating the remote operating device 28 disposed at a substantially central portion of the hand pusher 20. When the unlocking member 22 is lifted, the unlocking lever 24 is engaged with the actuating plate 34 to lift the locking member 32 upward, and the locking member 32 is released from engagement with the bracket 38.

Further, as shown in FIGS. 4 to 6, a locking member 26 which is slidable relative to the hand push rod 20 by operating the remote operating device 28 is provided in the middle portion of the hand pusher 20. On the other hand, as shown in FIGS. 5 and 6, each of the arm arms 60 is provided with a pair of locking projections 61a and 61b that engage with the locking members 26 to restrict the rotation of the hand pusher 20. By engaging the locking projection 61b (Fig. 6) provided at the rear with the locking member 26 and locking each other, as shown in Fig. 5, the hand pusher 20 will It is fixed in the push-back state, and at this time, the hand pusher 20 is stretched in parallel with the connecting rod 30. On the other hand, by engaging the locking projection 61a (Fig. 5) provided on the front side with the locking member 26 and locking each other, as shown in Fig. 6, the hand pusher 20 is fixed in the forward pushing state. At this time, the hand pusher 20 is stretched in a direction slightly parallel to the rear leg 14.

Next, the effect of folding the stroller 10 constituted by such a configuration will be explained.

First, if the hand pusher 20 is in the forward pushing position, the remote operating device 28 is operated first in the folding operation, and the locking member 26 is slid and the hand pusher 20 is moved from the forward pushing position (Fig. 6) to the pushback position. (Figure 5).

Further, in a state where the hand pusher 20 is disposed at the push-back position, first, the remote operation device 28 is operated to release the lock member 32 by the unlocking member 22, thereby releasing the engagement of the bracket 38 with the lock member 32. Next, the hand pusher 20 is once lifted upward and then pressed downward, whereby the bracket 38 is rotated relative to the rear leg 14 in the clockwise direction of FIG. With this operation, the arm 60 and the side frame 40 are rotated in the clockwise direction of the fifth figure with respect to the connecting rod 30. With this operation, as shown in Fig. 7, the side pusher 20 and the forefoot 12 are arranged to be slightly parallel in the side view, and the position of the hand pusher 20 is lowered.

The stroller 10 is folded as shown in Fig. 7 and is deflated in the front-rear direction and the up-and-down direction. Further, when the stroller 10 is unfolded from the folded state, it is only necessary to follow the reverse order of the folding operation, that is, the bracket 38 is rotated relative to the rear leg 14 in the counterclockwise direction in FIG. 60 and the side frame 40 are then directed to the seventh figure with respect to the connecting rod 30 Rotate in the counterclockwise direction.

Next, the structure and action of the sandwiching member 70 will be described in detail with reference mainly to Figs. Here, Fig. 1 is a partial perspective view showing the stroller, Fig. 2 is an exploded perspective view of Fig. 1, and Fig. 3 is a view for explaining the action of the sandwiching member.

First, the arm 60 will be further described in detail using the first to third figures. In particular, as shown in Fig. 2, the arm 60 includes a pair of arm bodies 62 having a U-shaped cross section that is open downward, and is composed of an upper portion 63 and both side portions 64 and 64; The projecting portions 66, 66 project rearward from the side portions 64 of the arm body 62. As shown in FIG. 4, the arm body 62 extends in the front-rear direction, and the projecting portion 66 extends from the both side portions 64 of the arm body 62 to the upper end portions of the connecting rod 30 disposed behind the arm body 62. side. Further, the extending portion 66 is connected to the connecting rod 30 so as to be rotatable by a connecting member (connecting shaft) 68 that penetrates the pair of extending portions 66 and the upper end portion of the connecting rod 30.

As shown in FIGS. 1 to 3, the sandwich preventing member 70 is configured to fill a gap between the connecting rod 30 and the arm 60, and more specifically, the connecting rod 30 and the upper portion 63 of the arm body 62. The gap created between the ends 65. In the present embodiment, the insertion preventing member 70 includes a mounting portion 72 that is fitted into the upper end portion of the connecting rod 30 formed of a tube, and a gap filling portion 76 that is disposed between the connecting rod 30 and the arm 60. The gap between the two.

In particular, as shown in FIG. 3, the attachment portion 72 includes a cover portion 73 having a cover function as a lockup connecting rod 30, and a pair of insertion portions 74 disposed below the cover portion and disposed on the cover portion Connect the rod inside. As shown in FIG. 2, a hole 74a into which the coupling member 68 can be inserted is formed in each of the insertion portions 74, Further, by inserting the connecting member 68 of the connecting arm 60 and the connecting rod 30 into the hole 74a, the insertion preventing member 70 can be supported by the attaching portion 72 while being fixed to the connecting rod 30.

On the other hand, the gap-filling portion 76 is suspended from the mounting portion 72 of the upper end portion of the insertion link 30 along the surface of the connecting rod 30 facing the arm body 62 side. The gap landfill portion 76 includes an arcuate portion 77 which is shown in Fig. 3 and has an arcuate profile in a section orthogonal to the axis of rotation of the arm 60 and the connecting rod 30, and the arc The portion 77 is facing the rear end 65 of the upper portion 63 of the arm body 62. As shown in FIG. 3, the arcuate portion 77 is formed by the upper portion 63 of the arm body 62 when the arm 60 is rotated with respect to the connecting rod 30 about the pivot shaft limited by the joint member 68. The shape of the movement track of the end 65.

The arcuate portion 77 has a certain thickness along the width direction, however, it is preferable that the arcuate portion 77 has a section along the moving path of the rear end 65 of the arm body 62 facing each other in the width direction. profile. At this time, the arcuate portion 77 has a contour corresponding to the contour along the width direction of the rear end 65 of the arm body 62 in the width direction. As shown in Fig. 2, in the present embodiment, the arcuate portion 77 has a linear contour along the width direction corresponding to the rear end 65 of the arm main body 62 having a linear contour in the width direction.

Next, the action of preventing the sandwiching member 70 when the stroller 10 is folded from the unfolded state (Fig. 6) and when it is unfolded from the folded state will be described.

As described above, when the stroller 10 is folded in the self-expanding state, the arm 60 is rotated relative to the connecting rod 30, and conversely, when the stroller 10 is deployed from the folded state, the arm 60 is also rotated relative to the connecting rod 30. . Again, as shown in Figure 3, When the arm 60 is rotated relative to the connecting rod 30, a gap is formed between the arm 60 and the connecting rod 30, and the size of the gap changes. This is because the rotating shaft of the arm 60 and the connecting rod 30 is not disposed. In the case where the connecting rod 30 faces the surface on the side of the arm body 62, in order to firmly connect the arm 60 and the connecting rod 30, the center of the connecting rod 30 (the surface facing the arm body 62 side (front side surface)) This phenomenon is inevitably generated when the surface of the opposite side (the center of the rear side) is joined to the projecting portion 66 of the arm 60.

This gap is generated between the rear end 65 of the upper portion 63 of the arm body 62 and the surface of the connecting rod 30. Further, when the arm 60 is disposed at the position where the gap is maximized, that is, the position of the connecting arm 60 with respect to the straight line of the rotating shaft and the rear end 65 of the connecting rod 30 and the surface of the connecting rod 30 is orthogonal. . Moreover, since the gap is exposed to the folding or unfolding of the stroller 10, there is a possibility that the clothes or fingers are caught in the gap.

On the other hand, in the present embodiment, the insertion preventing member 70 that fills the gap is supported by the upper end portion of the connecting rod 30, and the sandwiching member 70 is prevented from being disposed between the arm body 62 and the connecting rod 30. The arcuate portion 77 of the landfill portion 76 has a contour having a movement locus along the rear end 65 in a section orthogonal to the rotation axis of the arm 60, and therefore, the arc portion 77 is formed as a landfill due to the arm. Since the gap 60 changes with respect to the movement of the connecting rod 30, it is possible to prevent the laundry or the like from being caught between the arm body 62 of the arm 60 and the connecting rod 30 during the folding operation or the unfolding operation.

As described above, according to the present embodiment, the insertion preventing member 70 supported by the connecting rod 30 and filling the gap between the arm body 62 of the arm 60 and the connecting rod 30 is provided in the stroller 10, thereby preventing Clamp clothing, etc. The gap between the body 62 and the connecting rod 30.

Further, according to the present embodiment, the insertion preventing member 70 is supported by the upper end portion of the connecting rod 30 composed of the pipe material, and the sandwiching member 70 is prevented from functioning as a cover member for the connecting rod 30, and conversely, The prevention of the sandwiching member 70 is such that the generally used cover material has the function of filling the gap without increasing the number of parts.

Further, according to the present embodiment, the insertion preventing member 70 is fixed to the connecting rod 30 by the connecting member (shaft) 68 that connects the arm 60 and the connecting rod 30. Therefore, the clipping structure can be firmly mounted by a simple structure. Piece 70 does not increase the number of parts.

Further, according to the present embodiment, the insertion preventing member 70 includes the arcuate portion 77 which has an arc-like contour in a cross section orthogonal to the rotation axis of the arm 60 and the coupling rod 30. Further, the arcuate portion 77 has a contour along a moving path of the arm 60 of the arm body 62 along the pivoting arm 60. Therefore, the arc portion 77 can be opposed to the connecting rod 30 by the arm 60. The change in the size of the gap in the swirling is used to fill the gap, whereby the pinching of the clothes or the like can be more reliably prevented.

Further, according to the present embodiment, the insertion prevention member 70 includes the attachment portion 72 that is fitted into the coupling rod 30, and the gap-filling portion 76 that is connected to the arm body 62 from the attachment portion 72 toward the arm 60. Since the rods 30 are suspended from each other, the size of the entire stroller and the size of the connecting rod 30 or the arm rest 60 are not larger than usual, and the clothing or the like can be prevented from being caught.

Further, in the present embodiment, the insertion preventing member 70 is prevented from being fitted into the upper end of the connecting rod 30, and at the same time, the connecting member 68 is simultaneously connected to the connecting rod 30 and the arm 60. The example in which the connecting rod 30 is supported and fixed is provided. However, the present invention is not limited thereto. The gap preventing member 70 can be supported by various methods as long as it is disposed so as to be able to fill the gap between the arm 60 and the connecting rod 30. For example, the sandwiching prevention member 70 and the connecting rod 30 may be fixed only by being fitted to the upper end of the connecting rod 30, or as described in detail in the second embodiment, or by simultaneously with the connecting rod 30. The joining member 70 is fixed to the connecting rod 30 by the connecting member 68 penetrating without interposing the connecting rod 30.

It is known that the stroller folds identically. Fig. 21 is a view showing the state of the back pad support frame 134, the side plate 150, and the like in the folded state.

Next, the guard arms 118 of the stroller according to the present invention will be further described using Figs. 16 and 22 to 25.

Here, the 22nd to 25th drawings show explanatory views of the armrest 118 of the stroller.

As shown in FIGS. 16 and 22, the armrest 118 of the stroller of the present invention is extended between one of the pair of arms of the stroller 116 and the pair of end portions 180 coupled to the pair of arms 116 and disposed at Intermediate member 185 between a pair of end portions 180 Composition.

As shown in Figures 16, 22 and 23, the intermediate member 185 includes a core portion 170 extending between a pair of arms 116 and having elasticity; a pair of soft members 161 disposed to hold the core member. The portion 170 is softer than the core portion 170; and the protective member 162 is disposed on the outer surface of each of the soft members 161 while protecting the soft member 161.

In addition, as shown in FIG. 23, the core material portion 170 is composed of a polypropylene tape (hard member) 172 and a soft resin member 171 arranged in parallel with the polypropylene tape 172, and further, the soft resin member 171 The soft resin member 171a and the soft resin member 171b are combined to form a two-layer structure.

Moreover, as shown in Fig. 23, the outer surface of the protective member 162 is provided with a detachable outer cloth 163.

Further, as shown in Fig. 24, the core portion 170 is separated from the pair of soft members 161, and the core portion 170 and the soft member 161 are not fixed by an adhesive or the like.

That is, as shown in Fig. 24, each of the soft members 161 covers the outer surface by the protective member 162, and each of the soft members 161 is attached to the core portion 170 via the protective member 162.

At this time, each of the soft members 161 is covered by the protective member 162, and the protective member 162 is wound inside from the side of the soft member 161. Therefore, the protective member 162 is interposed between the core portion 170 and each of the soft members 161. Spaces 161a and 161a are formed between each of the soft members 161 and the core portion 170. Further, a space is formed between the both side portions of the core portion 170 and the exterior fabric 163. 170a, 170a.

Next, the action of this embodiment constituted by such a structure will be described.

As described above, the core portion 170 of the arm guard 118 is composed of a polypropylene tape 172 and a soft resin member 171 which are arranged side by side, wherein the polypropylene tape 172 is hard and hard, and the soft resin member 171 is Elastic, therefore, the arm 118 can achieve a moderate strength by the hardness of the polypropylene tape 172 of the core portion 170 while pushing back the force acting on the polypropylene tape 172 by the soft resin member 171 of the core portion 170. Therefore, excessive force can be prevented from acting on the polypropylene tape 172, and the durability of the arm guard 118 can be improved.

Accordingly, by using the elastic soft resin member 171 at the same time as the polypropylene tape 172, the durability of the arm guard 118 can be effectively improved. Further, since the weight of the soft resin member 171 is generally lighter than that of the polypropylene tape 172, the weight of the arm guard 118 can be reduced as compared with the use of the polypropylene tape 172 having a thick thickness to improve the durability of the arm guard 118.

Further, since the core portion 170 is composed of a rigid polypropylene tape 172 and a flexible soft resin member 171 which are provided in parallel, the shape of the arm guard 118 is not lost even if the arm guard 118 is moved up and down. And can maintain a certain shape.

That is, when the core material portion 170 uses only the polypropylene tape 172, since the polypropylene tape 172 has no elasticity, if the guard arm 118 is moved up and down, the shape of the arm guard 118 may lose its original shape. However, as in the present embodiment, In the form of the core portion 170 composed of the polypropylene tape 172 and the soft resin member 171, the armature 118 does not lose its original shape and can maintain its shape for a long period of time due to the elasticity of the soft resin member 171.

Further, since the soft member 161 is softer than the core portion 170, the touch feeling when the arm guard 118 is gripped can be made good. Further, since the soft member 161 supports the core portion 170 from the outside, the durability or elasticity of the arm 118 mainly obtained by the core portion 170 can be reinforced.

Moreover, as shown in Fig. 23, since the exterior fabric 163 is provided on the outer surface of the protective member 162, the feeling of the hand touching the arm 118 can be made good. Further, since the exterior fabric 163 can be detachably attached, the appearance of the arm guard 118 can be easily changed.

Further, as shown in Fig. 24, the core portion 170, the soft member 161, and the protective member 162 are covered by the exterior fabric 163, and are covered by the exterior fabric 163 from the outside. Further, the core member 170 and the soft member 161 are not connected by an adhesive or the like, and the soft member 161 is attached to the core member 170 in a separated state by the protective member 162 wound inside the soft member 161. When the arm guard 118 is moved in the vertical direction (see FIG. 25), the soft member 161 can freely slide on the core portion 170, and an excessive load can be prevented from acting on the soft member 161.

Further, as shown in Fig. 24, the soft member 161 covers the outer surface by the protective member 162, and the soft member 161 is attached to the core portion 170 via the protective member 162, whereby the protective member 162 can be used The protective member 162 is sandwiched between the soft member 161 and the core portion 170, so that the protective member 162 can be prevented from being detached from the soft member 161.

Next, a modification of the arm guard 118 will be described using FIG.

In the modification of the arm 118 shown in Fig. 26, a soft resin member 171 and a pair of polypropylene tapes provided to sandwich the soft resin member 171 are used. The core portion 170 of the 172 is replaced by a core portion 170 composed of a polypropylene tape 172 and a soft resin member 171 arranged in parallel with the polypropylene tape 172, and other systems and 22 to 25 are shown. The embodiments are substantially the same.

In the modification shown in Fig. 26, the same portions as those in the embodiment shown in Figs. 22 to 25 are denoted by the same reference numerals, and the detailed description thereof will be omitted.

As shown in Fig. 26, the soft resin member 171 is sandwiched and a pair of polypropylene tapes 172 are provided on both surfaces of the soft resin member 171. Therefore, the force acting on the core portion 170 can be evenly dispersed to the soft resin. The member 171 and the respective polypropylene tapes 172 provided on both sides of the soft resin member 171 can further improve the durability of the arm guard 118 while reliably preventing the arm guard 118 from being deformed from the original shape due to the reverse up and down movement. .

According to the present invention, it is possible to provide a guardrail for a stroller which is light and durable, and which, even if it is used repeatedly, does not change its original shape for a long period of time.
