As described above, the baby carriage 10 is folded as shown in Fig. 7 and becomes compact in the front-rear direction and the vertical direction. In addition, in order to expand the baby carriage 10 from the folded state, the reverse sequence to the folding operation described above may be performed. 7, the bracket 38 is rotated counterclockwise in FIG. 7 with respect to the horn 14 and the armrest 60 and the side frame 40 are thereby rotated with respect to the connecting lever 30 It may be rotated in the clockwise direction.

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

1 to 3, the armrest 60 will be described in more detail. 2, the armrest 60 includes an armrest main body 62 having an approximately U-shaped cross section opened downward and having an upper portion 63 and two side portions 64, 64 And a pair of extending projections 66 and 66 extending 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-rear direction. The extended projections 66 extend from both side portions 64 of the armrest main body 62 to both sides of the upper end portion of the connecting lever 30 disposed at the rear of the armrest main body 62. The extending projections 66 are rotatably connected to the connecting levers 30 by a pair of extending projections 66 and connecting members (connecting shafts) 68 passing through the upper ends of the connecting levers 30 .

1 to 3, the jamming preventing member 70 has a gap formed between the connecting lever 30 and the armrest 60, more specifically, the gap between the connecting lever 30 and the upper portion 63 of the armrest main body 62 And the rear end 65 of the front end portion 65a. In the present embodiment, the jam-preventing member 70 is provided with an attachment portion 72 to be fitted into the upper end portion of the connection lever 30 made of a pipe, And a gap-filling portion 76 which is formed on the surface of the substrate.

3, the attaching portion 72 includes a lid portion 73 that functions as a lid for sealing the upper portion of the connecting lever 30, and a lid portion 73 which is provided below the lid portion, And a pair of insertion portions 74. As shown in Fig. 2, each insertion portion 74 is formed with a hole 74a into which a connecting member 68 is inserted. The coupling member 68 connecting the armrest 60 and the coupling lever 30 is inserted into the hole 74a so that the jamming prevention member 70 is fixed to the coupling lever 30 through the attachment portion 72 .

The gap filling portion 76 is extended along the surface of the connecting lever 30 facing the armrest main body 62 from the attaching portion 72 fitted in the upper end portion of the connecting lever 30. [ The gap-embedded portion 76 includes an arcuate portion 77 having an arc-shaped outline in Fig. 3, which is viewed from a cross section orthogonal to the axis of rotation of the armrest 60 and the connecting lever 30, The arcuate portion 77 faces the rear end 65 of the upper portion 63 of the armrest main body 63. 3, the arcuate portion 77 has an arcuate body 62 (see FIG. 3) when the armrest 60 rotates about the connecting lever 30 about the rotational axis defined by the connecting member 68 ) Of the rear end 65 of the upper portion 63. [0064] As shown in Fig.

The arc-shaped portion 77 has a constant thickness along the width direction, but the arc-shaped portion 77 has a circular cross-sectional contour along the movement trajectory of the rear end 65 of the armrest main body 62 facing at any position in the width direction It is desirable to have. In this case, the arcuate 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. 2, the rear end 65 of the armrest main body 62 corresponds to a linear contour along the width direction, and the circular arc portion 77 also has a linear shape along the width direction It has a contour.

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

As described above, when the baby carriage 10 is folded from the unfolded state, the armrest 60 rotates with respect to the connecting lever 30. [ Conversely, when the baby carriage 10 is expanded from the folded state, the armrest 60 also rotates with respect to the connecting lever 30. 3, when the armrest 60 rotates with respect to the connecting lever 30, a gap is created between the armrest 60 and the connecting lever 30, and the size of the gap is changed. This is a phenomenon caused by the fact that the armature 60 and the pivoting axis of the connecting lever 30 are not disposed on the surface of the connecting lever 30 facing the armrest main body 62. (Front surface) and the opposite surface (rear surface) of the connecting lever 30 (the front surface and the rear surface) facing the armrest main body 62 in order to firmly connect the armrest 60 and the connecting lever 30, This phenomenon inevitably occurs when the extension projection 66 of the armrest 60 is connected.

This gap is formed between the rear end 65 of the upper portion 63 of the armrest main body 62 and the surface of the connecting lever 30. In a case where the armrest 60 is disposed at a position where a straight line connecting the rotation shaft and the rear end 65 of the armrest 60 to the connection lever 30 is orthogonal to the surface of the connection lever 30, The largest size. Since this gap is exposed toward the person folding or deploying the baby carriage 10, there is a possibility that the garment and the finger are caught in the gap.

On the other hand, in the present embodiment, the jamming preventing member 70 for covering the gap is supported on the upper end portion of the connecting lever 30. The arcuate portion 77 of the gap embedding portion 76 disposed between the armrest main body 62 and the connecting lever 30 of the jamming preventing member 70 is formed in a cross section orthogonal to the rotational axis of the armrest 60 And has a contour along the movement trajectory of the rear end 65 when viewed. Therefore, the arcuate portion 77 is formed so as to fill the gap which is changed by the movement of the armrest 60 relative to the connecting lever 30. Therefore, it is possible to prevent the garment or the like from being caught in the gap formed between the armrest main body 62 and the connecting lever 30 of the armrest 60 during the folding operation or the expansion operation.

As described above, according to this embodiment, the jamming preventing member 70, which is supported by the connecting lever 30 and fills the gap between the armrest main body 62 and the connecting lever 30 of the armrest 60, Respectively. Therefore, it is possible to prevent garment or the like from being caught in the gap between the armrest main body 62 and the connecting lever 30. [

According to the present embodiment, the jamming preventing member 70 is supported on the upper end of the connecting lever 30 made of a pipe material, and the jamming preventing member 70 also functions as a lid member of the connecting lever 30 . Conversely, the jam-preventing member 70 has a function of filling a gap in a commonly used lid member and does not increase the number of parts.

According to the present embodiment, the jamming preventing member 70 is fixed to the connecting lever 30 by a connecting member (shaft) 68 connecting the armrest 60 and the connecting lever 30. Therefore, the jam-preventive member 70 can be firmly attached by a simple structure without increasing the number of parts.

In addition, according to the present embodiment, the jam-preventing member 70 has the arcuate portion 77 having an arc-shaped outline in a cross section perpendicular to the axis of rotation of the armrest 60 and the connecting lever 30. [ The arcuate portion 77 has a contour along the movement path of the rear end 65 of the armrest main body 62 of the armrest 60 during the rotation. Therefore, the arc-shaped portion 77 can fill the gap in accordance with the change in the size of the gap in the pivotal movement of the armrest 60 relative to the connecting lever 30. This makes it possible to more reliably prevent the garment from being caught.

In addition, according to the present embodiment, the jamming preventing member 70 includes the attachment portion 72 to be fitted into the connection lever 30, the attachment portion 72 to the armrest body 62 of the armrest 60, And a gap-embedded portion 76 that is formed between the first electrode layer 30 and the second electrode layer 30. Therefore, the size of the entire stroller, and furthermore, the size of the connecting lever 30 and the armrest 60 can be prevented from becoming larger than usual, and the interference of clothes or the like can be prevented.

The jamming preventing member 70 is fitted in the upper end of the connecting lever 30 and is also penetrated by the connecting member 68 together with the connecting lever 30 and the armrest 60, An example is shown in which it is supported and fixed by the connecting lever 30, but the present invention 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 interference preventing member 70 can be supported by various methods. It is possible to fix the jamming prevention member 70 and the coupling lever 30 only by being fitted to the upper end of the coupling lever 30, for example. Alternatively, as described in detail in the second embodiment, the jam-preventing member 70 can be inserted into the connecting lever (30) only by being penetrated together with the connecting lever (30) by the connecting member (68) 30).

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

Here, Figs. 22 to 25 are views showing a description of the guide arm 118 of the baby carriage.

16 and 22, the guide arm 118 of the baby carriage of the present invention is extended and disposed between a pair of armrests 116 of the baby carriage, and a pair of armrests 116 connected to the pair of armrests 116 And an intermediate member 185 provided between the end portion 180 and the pair of end portions 180.

16, 22, and 23, the intermediate member 185 includes a core portion 170 extending between the pair of armrests 116 and having a spring property, A pair of flexible members 161 which are provided in a standing manner and are softer than the core portion 170 and a protective member 162 which is provided on the outer surface of each flexible member 161 and protects the flexible member 161, .

23, the core portion 170 is composed of a polypropylene belt (rigid member) 172 and a soft resin member 171 arranged in parallel with the polypropylene belt 172 . The soft resin member 171 is composed of a soft resin member 171a and a soft resin member 171b and has a two-layer structure.

As shown in Fig. 23, the outer surface of the protective member 162 is provided with an outer cloth 163 that can be detached.

24, the core portion 170 and the pair of soft members 161 are separately provided, and the core portion 170 and the soft member 161 are not fixed by an adhesive or the like.

24, each soft member 161 is covered with an outer surface by a protective member 162, and each soft member 161 is attached to the core portion 170 through a protective member 162 Respectively.

In this case, each soft member 161 is covered on its outer side by the protective member 162, and the protective member 162 is turned on the inner side from the side of the soft member 161. Therefore, a protective member 162 is interposed between the core member 170 and each soft member 161, and spaces 161a and 161a are formed between the soft members 161 and the core member 170 have. In addition, spaces 170a and 170a are also formed between both sides of the core member 170 and the external cloths 163.

Next, the operation of the present embodiment having such a configuration will be described.

As described above, the core portion 170 of the guide arm 118 is composed of the polypropylene belt 172 arranged in parallel and the soft resin member 171. Among them, the polypropylene belt 172 is rigid and rigid, and the soft resin member 171 has elasticity. Therefore, the guide arm 118 can attain an appropriate strength by the rigidity of the polypropylene belt 172 of the core portion 170, and at the same time, It is possible to push out the force applied to the polypropylene belt 172, so that the polypropylene belt 172 can be prevented from being exerted with an excessive force, and the durability of the guide arm 118 can be improved.

By using the soft resin member 171 having elasticity together with the polypropylene belt 172, the durability of the guide arm 118 can be improved efficiently. In addition, the weight of the soft resin member 171 is generally lighter than the weight of the polypropylene belt 172. Therefore, the weight of the guide arm 118 can be reduced as compared with the case where the durability of the guide arm 118 is improved by using the polypropylene belt 172 having a large thickness.

Since the core portion 170 is composed of the rigid polypropylene belt 172 provided in parallel and the soft resin member 171 having elasticity, the guide arm 118 can be moved up and down repeatedly, Shape can be kept constant without being disturbed.

That is, when only the polypropylene belt 172 is used as the core portion 170, since the polypropylene belt 172 has no elasticity, when the guide arm 118 is repeatedly moved up and down, The core member 170 composed of the polypropylene belt 172 and the soft resin member 171 is used as in the present embodiment so that the elasticity of the soft resin member 171 , The guide arm 118 is not disturbed from the original shape and can maintain its shape for a long period of time.

Since the soft member 161 is more flexible than the core member 170, it is possible to improve the feeling when the guide member 118 is held. Since the soft member 161 supports the core portion 170 from the outside, the durability and elasticity of the guide arm 118 obtained mainly by the core portion 170 can be supplemented.

As shown in Fig. 23, an external cloth 163 is provided on the outer surface of the protective member 162. Fig. Therefore, the feel of the guide arm 118 can be improved. Since the outer cloth 163 is detachable, the outer appearance of the guide arm 118 can be easily changed.

24, the core portion 170, the soft member 161, and the protection member 162 are covered with the outer cloth 163, and the outer cloth 163 is formed by the outer cloth 163 from the outside And is pressurized. The soft member 161 is not bonded between the core member 170 and the soft member 161 and the core member 170 is fixed to the soft member 161 through the protective member 162, As shown in Fig. Therefore, when the guide arm 118 is moved in the vertical direction (see FIG. 25), the soft member 161 can freely slide on the core portion 170, Can be prevented.

24, the outer surface of the soft member 161 is covered with the protective member 162, and the soft member 161 is attached to the core portion 170 with the protective member 162 interposed therebetween have. Since the protective member 162 can be interposed between the soft member 161 and the core member 170 by inserting the protective member 162 into the soft member 161, Can be prevented.

Next, a modified example of the guide arm 118 will be described with reference to Fig.

A modification of the guide arm 118 shown in Fig. 26 includes a polypropylene belt 172 and a soft resin member 171 disposed in parallel with the polypropylene belt 172, instead of the core portion 170, A core portion 170 composed of a pair of polypropylene belts 172 provided between the resin member 171 and the soft resin member 171 is used. .

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

26, a pair of polypropylene belts 172 are provided on both sides of the soft resin member 171 with the soft resin member 171 interposed therebetween. Therefore, the force applied to the core portion 170 can be balancedly dispersed in the soft resin member 171 and the respective polypropylene belts 172 provided on both surfaces of the soft resin member 171. Therefore, the durability of the guide arm 118 can be further improved, and at the same time, the guide arm 118 can reliably be prevented from being deformed from its original shape by repeating the upward and downward movement.

According to the present invention, it is possible to provide a guide arm of a baby carriage which is lightweight, has high durability, and has a regular shape that does not change from its original shape for a long period of time even if used repeatedly.

Thus, the infant seat 221 can be selectively inserted into the baby carriage body 210 so as to be reversed, so that the infant seat 221 can be manually or face-to-face from the back of the infant.

28, reference numeral 230 denotes a brake bearing mounted on the lower end of the right and left rear horn 214, respectively. One rear wheel axle 231 is mounted on the left and right brake bearings 230 (only one of which is shown in the drawing). The rear wheel axle 231 is fitted with a plastic tubular collar 232 and the rear wheel axle 231 is inserted into the shaft hole 233 of the brake bearing 230. A cylindrical collar 232 is positioned at the end of the rear wheel axle 231 and protrudes from mutually facing side surfaces of the left and right brake bearings 230. 29, a rear wheel 213 composed of a single wheel is attached to the rear wheel axle 231 protruding from the other side surface of the brake bearing 230. As shown in Fig.

The brake bearing 230 is provided with a connecting protrusion 234 protruding in a direction parallel to the collar 232 at a position adjacent to the cylindrical collar 232 projecting from the brake bearing 230 And is integrally formed. A claw 237 is formed on a side surface of the connecting protrusion 234 to engage with an engaging hole 236 formed in a connecting pipe 235 connecting the left and right brake bearings 230. The connection pipe 235 is formed in a substantially elliptical shape and includes a tubular collar 232 protruded from the brake bearing 230 and a connecting protrusion 234 adjacent to the collar 232, And the connecting pipe 235 has an elliptical inner edge corresponding to this elliptical outer edge.

As described above, after the rear wheel axle 231 is inserted into the brake bearing 230, a cylindrical collar 232 protruding from the brake bearing 230 and a connection (not shown) adjacent to the collar 232 And the claw 237 formed in the connecting protrusion 234 is engaged with the engaging hole 236 provided in the connecting pipe 235. The protrusion 234 of the connecting pipe 235 is pressed into the end of the connecting pipe 235, The left and right brake bearings 230 are connected to each other by a connecting pipe 235. [

In this way, in this embodiment, since the cylindrical collar 232 mounted on the rear wheel axle 231 is press-fitted into the connecting pipe 235, vibration noise of the connecting pipe 235 is generated by the collar 232 . The left and right brake bearings 230 are connected to each other by engaging the claws 237 formed in the connecting protruding portions 234 with the engaging holes 236 provided in the connecting pipe 235. Therefore, there is no need to use a special fastening part for connecting the connecting pipe 235 and the left and right brake bearings 230, thereby reducing the number of parts and weight.

In the above embodiment, the infant seat is applied to a baby carriage which can be attached to the baby carriage body by changing the longitudinal direction. However, the baby carriage can be applied to any type of baby carriage if the baby carriage is composed of left and right rear wheels.

As described above, according to the present invention, the left and right brake bearings attached to the left and right rear horns respectively have axles supported by a pair of left and right rear wheels, and the left and right brake bearings are connected by a connecting pipe. Therefore, one rear wheel axle can be provided on one side, so that the weight of the rear wheel axle can be lighter than that of a conventional rear wheel axle. Further, since the left and right brake bearings are connected only by the connecting pipe, the weight of the conventional connecting parts can be reduced.

As described above, according to the present invention, it is possible to prevent garment or the like from being caught in gaps between armrests and other constituent members rotatably connected to the armrests during the folding operation or the expanding operation, The guide arm of the baby carriage and the baby carriage can be provided.
