In recent years, a space has been provided in a railway vehicle so that passengers can get on in a wheelchair. Since this space may be used by standing passengers other than wheelchair-using passengers, it is desirable that a support structure that can be used by both wheelchair-using passengers and standing passengers is placed in this space.

As described above, there is a waist support as a structure for supporting the standing customers, but the waist support is formed by surrounding a cushion material or the like with a flexible sheet member such as a moquette. A seat member such as a moquette is initially in a pulled state, but gradually loosens to cause wrinkles. As a result, when a standing customer leans on his / her back, he / she may feel uncomfortable. Moreover, the appearance is inferior to that in the state where the seat member is pulled.

Therefore, an object of the present invention is to provide a passenger support structure for a railway vehicle that can support passengers and standing passengers who use wheelchairs and is less likely to cause wrinkles.

In the present invention, the base material including the bottom plate inclined with respect to the horizontal or arranged at right angles to the horizontal, and one end and the other end thereof cover one surface side of the base material. attached to the substrate, and a support and a sheet member having a detachable flexible to the substrate, located on the other side of the substrate, wherein between the base sheet It is provided with a handrail that sandwiches the member, and the center of the handrail is located at a height below the upper end of the support and is on a vertical line passing through one end of the support on the other surface side in the horizontal direction or the said. It is located on the side opposite to the support with respect to the vertical line, and the upper end of the handrail is located at a height equal to or higher than the upper end of the support by the length of the radius of the handrail.

In the above configuration, the handrail can be used while the passenger is in a wheelchair, and the standing passenger can lean on the support by placing the waist or the buttocks on the support. The support and the handrail are lined up, but when the standing customer puts the waist or hips on the support, most of the weight is applied to the support, and the handrail bears almost no weight. Therefore, the standing guest can lean on the support without feeling uncomfortable with the handrail.
Further, since the sheet member is sandwiched between the handrail and the base material, the sheet member is less likely to bend. Therefore, wrinkles are less likely to occur on the seat member.
From the above, a passenger support structure that can be used by passengers in wheelchairs and standing passengers and is less likely to cause wrinkles can be obtained.
Further, since the support and the handrail are in contact with each other and no gap is formed between them, there is no possibility that a passenger's finger may be caught between the support and the handrail or dust may enter.

Further, in the above configuration, it is preferable that the sheet member is in the limit compression state by sandwiching the sheet member between the bottom plate and the handrail.

By sandwiching the seat member with the bottom plate and the handrail until the limit compression state is reached, the seat member bends even if one surface side of the seat member is pulled when the standing customer places the waist or buttock on the support. Hateful. Therefore, wrinkles are less likely to occur on the seat member.

Further, in the above configuration, the base material includes a first cushion material arranged on one surface side of the bottom plate and a second cushion material arranged on the other surface side, and the second cushion. The material is arranged between the bottom plate and the handrail, and the second cushion material is in a limit compression state by sandwiching the second cushion material between the bottom plate and the handrail. preferable.

By pressing the second cushion material with the support and the handrail until the limit compression state is reached, the seat member is also brought into the limit compression state. As a result, the seat member is less likely to bend, so that the seat member is less likely to wrinkle over a long period of time.

The railroad vehicle of the present invention has the above-mentioned support structure, the support is attached to the wall of the railcar via an attachment, the handrail is connected to the attachment, and the support is attached to the attachment. On the other hand, it is removable.

In the above configuration, passengers and standing passengers using wheelchairs in a railway vehicle can use the support structure described above. Further, since the seat member of the support is less likely to bend, wrinkles are less likely to occur. Further, since only the support can be removed from the fixture and replaced, the support can be easily replaced.

According to the present invention, it is possible to provide a passenger support structure for a railway vehicle that can be used by passengers and standing passengers using a wheelchair and is less likely to cause wrinkles.

It is a top view of the support structure shown in FIG. 2 (enlarged view of III of FIG. 1). It is sectional drawing (cross-sectional view along line IV-IV of FIG. 3) of the support structure. It is sectional drawing which shows the process of attaching a support structure to a side wall in order. It is sectional drawing of the support structure of 2nd Embodiment.

[First Embodiment]
FIG. 1 shows a view of the inside of one end of a railway vehicle 1 as viewed from above. A space 2 is formed at one end of the railroad vehicle 1 so that passengers can get on in a wheelchair. The space 2 faces the first side wall 3. A seat 5 is attached to the second side wall 4 facing the first side wall 3. Space 2 may be used by standing passengers other than passengers in wheelchairs.

A support structure 6 for supporting passengers is arranged in the space 2. As shown in FIG. 2, the support structure 6 is arranged at a height lower than that of the window 7, and is located at a height near the waist or hips of the standing passenger. The support structure 6 extends in the longitudinal direction of the vehicle from the end of the vehicle to the vicinity of the front of the opening / closing door. The support structure 6 is attached to the first side wall 3 by three attachments 8, 9, and 10. The three fixtures 8, 9 and 10 have the same configuration and are evenly spaced in the longitudinal direction of the vehicle (see FIG. 3).

As shown in FIG. 4, the fixture 10 includes a support facing plate 11 arranged to face the support 21 described later, a handrail contact plate 12 in contact with the handrail 22 described later, and a first side wall. It has a side wall fixing plate 13 fixed to 3.

The support facing plate 11 is inclined with respect to the horizontal direction so that the upper end portion approaches the first side wall 3. The handrail contact plate 12 is inclined in the horizontal direction so that the lower end portion is close to the first side wall 3 and the upper end portion is away from the first side wall 3. The support facing plate 11 and the handrail contact plate 12 form an inverted V shape by connecting the upper ends to each other. A side wall fixing plate 13 is arranged below the lower end of the handrail contact plate 12. The side wall fixing plate 13 is arranged along the first side wall 3, and is fixed to the first side wall 3 by using, for example, bolts and nuts. The lower end of the handrail contact plate 12 is connected to the upper end of the side wall fixing plate 13. As a result, the support facing plate 11, the handrail contact plate 12, and the side wall fixing plate 13 are integrated.

The support facing plate 11, the handrail contact plate 12, and the side wall fixing plate 13 are formed of, for example, a metal plate. When the support facing plate 11, the handrail contact plate 12 and the side wall fixing plate 13 are formed of a metal plate, the upper ends of the support facing plate 11 and the handrail contact plate 12 are welded to each other, and the handrail contact plate 12 And the upper end of the side wall fixing plate 13 can be welded.

As shown in FIG. 4, the support structure 6 has a support 21 having a substantially semi-elliptical cross section and a handrail 22 having a circular shape. As shown in FIG. 3, the support 21 and the handrail 22 extend in the longitudinal direction of the vehicle.

The support 21 has a base material 33 including a bottom plate 31 and a cushioning material 32, and a sheet member 34 arranged so as to surround the base material 33. The sheet member 34 can maintain a state in which the bottom plate 31 and the cushion material 32 are united as one base material 33.

The bottom plate 31 is inclined with respect to the horizontal direction so that the upper end portion approaches the first side wall 3. The bottom plate 31 is formed of a hard plate-like member capable of holding the cushion material 32. A bent portion 31x that is bent to the left in FIG. 4 (in a direction away from the first side wall 3) is formed near the center of the bottom plate 31. A male or female first upper surface fastener 41 (for example, Magic Tape (registered trademark)) is attached above the bent portion 31x to the right surface 31a (the surface facing the first side wall 3) of the bottom plate 31, and the bent portion is formed. A male or female first lower surface fastener 42 (eg, Velcro®) is attached below the 31x. A female or male second upper surface fastener 51 sewn to the upper end of the seat member 34 is engaged with the first upper surface fastener 41, and the first lower surface fastener 42 is engaged with the lower other end of the seat member 34. The sewn female or male second lower surface fastener 52 engages. The upper surface fastener 110 composed of the first upper surface fastener 41 and the second upper surface fastener 51 and the lower surface fastener 120 composed of the first lower surface fastener 42 and the second lower surface fastener 52 are on both sides of the fixtures 8, 9, and 10. (See FIG. 3). The upper surface fastener 110 and the lower surface fastener 1 20, the sheet member 34 is detachable to the base 33.

The cushion material 32 includes a first cushion material 61 mainly arranged on the left side in FIG. 4 with respect to the bottom plate 31, and a second cushion material 62 slightly arranged on the upper right side in FIG. 4 with respect to the bottom plate 31. Have. Here, the right side in FIG. 4 is the side closer to the first side wall 3, and the left side in FIG. 4 is the far side of the first side wall 3. The first cushion material 61 is arranged between the left surface 31b of the bottom plate 31 and the seat member 34. The second cushion material 62 is arranged above the upper surface fastener 110 in a slight gap between the right surface 31a of the bottom plate 31 and the seat member 34.

A spacer 70 is arranged in place of the second cushion material 62 in a slight gap below the lower surface fastener 120.

The seat member 34 is a flexible sheet-like member such as a moquette, and is arranged so as to cover the first cushion material 61 and the second cushion material 62. At the initial stage when the upper end and the lower end of the seat member 34 are attached to the right side 31a of the bottom plate by the upper surface fastener 110 and the lower surface fastener 120, the male and female fasteners of the upper surface fastener 110 are firmly engaged with each other. The seat member 34 is pulled and is not wrinkled.

The support 21 is, for example, screwed to the support facing plate 11 of the fixture 10 at a portion where the upper surface fastener 110 and the lower surface fastener 120 are not arranged. The support 21 projects from the support facing plate 11 toward the first side wall 3, and the upper right end of the support 21 does not face the support facing plate 11.

The handrail 22 is located on the right side of the support 21, and is arranged so as to be in contact with the upper right end of the support 21 and the upper end of the handrail contact plate 12. For the handrail 22, for example, a metal pipe having a diameter that can be grasped by passengers can be used. The handrail 22 is connected to the handrail contact plate 12 by welding or the like.

As shown in FIG. 4, when the support structure 6 is attached to the first side wall 3 by the attachment 10, the bottom plate 31 and the handrail 22 sandwich the seat member 34 and the second cushion member 62. The seat member 34 and the second cushion material 62 are in the limit compression state. The limit compression state is a state in which compression is not performed even if the pressure is further increased.

By placing the waist or hips on the left side of the support 21, the support 21 bears the weight of the standing from above or from the upper left to the bottom. As a result, the left side of the seat member 34 is pulled downward, and the upper surface fastener 110 is likely to be disengaged. However, since the bottom plate 31 and the handrail 22 sandwich the seat member 34 and the second cushion member 62, the left side of the seat member 34 is unlikely to be pulled downward. Therefore, since the top fastener 110 is hardly disengaged, the seat member 34 hardly bends and wrinkles are unlikely to occur.

Center c ₁ of the handrail 22 is positioned on the upper end t ₁ of the height of the support 21 (region R _1). Further, the center c _{1 of the} handrail 22 is located on the vertical line l ₁ passing through the rightmost end s ₁ of the support 21 in the horizontal direction or on the side opposite to the support 21 (region R ₂ ) with respect to the vertical line l ₁ . are doing.

Further, when the radius of the handrail 22 is r ₁ , the upper end U of the handrail 22 is located at a height (region R ₃ ) lower than the upper end t ₁ of the support 21 by a radius r _1. ing.

When the center c _{1 of the} handrail 22 is located in the area where the area R ₁ and the area R ₂ overlap, and the upper end U of the handrail 22 is located in the area R ₃ , the passenger is in a wheelchair. It is located in an area that is easy to grip while riding. Further, when the standing customer puts the waist or the buttocks on the support 21, most of the weight of the standing customer is applied to the support 21, and the handrail 22 is hardly weighted. Therefore, the standing customer can lean on the support 21 without feeling uncomfortable with the handrail 22.

Next, a method of attaching the support structure 6 to the first side wall 3 will be described with reference to FIG.

First, as shown in FIG. 5A, the handrail 22 is connected to the handrail contact plate 12 of the fixture 10 by welding or the like. By changing the inclination angle of the support plate 11 when assembling the attachment 10, the inclination angle of the support 21 and the bottom plate 31 to be attached in a later step can be set to a desired angle.

Next, the side wall fixing plate 13 of the fixture 10 is fixed to the first side wall 3 using bolts, nuts, or the like (see FIG. 5B).

Subsequently, the support 21 is attached to the support facing plate 11 (see FIG. 5C). Since the support 21 is removable from the support facing plate 11, when the support 21 deteriorates, the support 21 can be removed from the support facing plate 11 and easily replaced with another support. ..

As described above, according to the present embodiment, the following effects are obtained.
Passengers can use the handrail 22 while in a wheelchair, and standing passengers can lean on the support 21 with their waist or hips resting on the support 21. Although the support 21 and the handrail 22 are arranged side by side, most of the weight of the standing passenger is applied to the support 21, and the handrail 22 bears almost no weight. Therefore, the standing customer can lean on the support 21 without feeling uncomfortable with the handrail 22.
Therefore, the support structure 6 is a structure that can be used by passengers in wheelchairs and standing passengers.
Further, since the seat member 34 and the second cushion member 62 are sandwiched between the bottom plate 31 and the handrail 22, the seat member 34 is unlikely to bend even if most of the standing customers are applied to the support 21. Therefore, the seat member 34 is less likely to wrinkle.
Further, since the support 21 and the handrail 22 are in contact with each other and no gap is formed between them, there is no possibility that a passenger's finger may be caught or dust may enter between the support 21 and the handrail 22. ..

Further, by sandwiching the seat member 34 and the second cushion material 62 with the bottom plate 31 and the handrail 22 until the limit compression state is reached, when the standing customer puts the waist or buttock on the support 21, the seat member 34 Even if one surface side is pulled, the seat member 34 does not easily bend. Therefore, wrinkles are less likely to occur on the seat member 34.

Further, since the support 21 is removable from the support plate 11, when only the support 21 of the support structure 6 needs to be replaced, only the support 21 can be easily replaced.

[Second Embodiment]
Next, the second embodiment of the present invention will be described with reference to FIG. The differences between the second embodiment and the first embodiment are 1) the configuration of the support 221 and 2) the positional relationship between the support 221 and the handrail 22. The same reference numerals are used for the same configurations as those in the first embodiment described above, and the description thereof will be omitted as appropriate.

The fixture 210 has a support facing plate 211, a handrail contact plate 12, and a side wall fixing plate 13. The support facing plate 211 is arranged at right angles to the horizontal direction. The support 221 is attached to the support facing plate 211 using screws or the like (not shown).

The support structure 206 includes a support 221 and a handrail 22. The support 221 has a base material 233 including a bottom plate 231 and a cushioning material 232, and a seat member 234 arranged so as to surround the base material 233. The sheet member 234 is a flexible sheet-like member such as a moquette, and covers the upper surface, the left surface, and the lower surface of the base material 233.

The bottom plate 231 is arranged at right angles to the horizontal direction. The bottom plate 231 is formed of a hard plate-like member capable of holding the cushion material 232.

A male or female first upper surface fastener 241 (for example, Magic Tape (registered trademark)) is attached to the right side 233a of the base material 233 (the right side of the bottom plate 231 and the surface facing the first side wall 3) above the center. A male or female first lower surface fastener 242 (eg, Velcro®) is attached below the center. A female or male second upper surface fastener 251 sewn on the upper end of the seat member 234 is engaged with the first upper surface fastener 241, and the first lower surface fastener 242 is engaged with the lower other end of the seat member 234. The sewn female or male second underside fastener 252 engages. The upper surface fastener 310 composed of the first upper surface fastener 241 and the second upper surface fastener 251 and the lower surface fastener 320 composed of the first lower surface fastener 242 and the second lower surface fastener 252 are arranged on both sides of the fixture 210. There is. The upper surface fastener 310 and the lower surface fastener 320 make the seat member 234 removable from the base material 233.

Above the top fastener 310, a spacer 271 is arranged in a slight gap between the seat member 234 and the right surface 233a of the bottom plate 231. Further, below the lower surface fastener 320, a spacer 272 is arranged in a slight gap between the seat member 234 and the right surface 233a of the bottom plate 231.

The support 221 is longer in the vertical direction than the support facing plate 211, and the upper right end portion and the right lower end portion of the support 221 do not face the support facing plate 211.

The handrail 22 is located on the right side of the support 221 and is arranged so as to be in contact with the upper right end of the support 221 and the handrail contact plate 12. The handrail 22 is connected to the handrail contact plate 12 by welding or the like.

In the state where the support structure 206 is attached to the first side wall 3 by the attachment 210, the seat member 234 is in the limit compression state because the bottom plate 231 and the handrail 22 sandwich the seat member 234.

By placing the waist or buttock on the left side or the upper surface of the support 221 the standing person, the weight of the standing person is applied to the support 21 from the upper side, the left side, or the upper left side to the lower side. As a result, the seat members 234 arranged on the left side and the upper surface side of the support 221 are pulled downward, and the upper surface fastener 310 is likely to be disengaged. However, since the bottom plate 231 and the handrail 22 is sandwiched a sheet member 234, the sheet member 2 34 is not easily pulled downward. Therefore, since the top fastener 310 is hardly disengaged, the seat member 234 hardly bends and wrinkles are unlikely to occur.

The center c _{1 of the} handrail 22 is located at a height (region R ₁₁ ) equal to or less than the upper end t ₂ of the support 221. Further, the center c _{1 of the} handrail 22 is located on the vertical line l ₂ passing through the rightmost end s ₂ of the support 221 in the horizontal direction or on the side opposite to the support 221 (region R ₁₂ ) with respect to the vertical line l ₂ . are doing.

Further, the upper end U of the handrail 22 is located at a height (region R ₁₃ ) lower than the upper end t ₂ of the support 21 by a length of a radius r ₁ .

When the center c _{1 of the} handrail 22 is located in the area where the area R ₁₁ and the area R ₁₂ overlap, and the upper end U of the handrail 22 is located in the area R ₁₃ , the passenger is in a wheelchair. It is located in an area that is easy to grip while riding. Further, when the standing customer puts his / her waist or hips on the support 221, most of the weight of the standing customer is applied to the support 221 and almost no weight is applied to the handrail 22. Therefore, the standing customer can lean on the support 221 without feeling uncomfortable with the handrail 22.

As described above, according to the second embodiment, the support structure 206 is a structure that can be used by passengers and standing passengers in a wheelchair, as in the first embodiment. In addition, the seat member 234 is less likely to wrinkle. Further, since the support 221 and the handrail 22 are in contact with each other and no gap is formed between them, there is no possibility that a passenger's finger may be caught or dust may enter between the support 221 and the handrail 22. ..
