First, each direction described in each figure is defined. The longitudinal direction (rail direction) of the railroad vehicle 1 is the x direction, the width direction (sleeper direction) thereof is the y direction, and the height direction (vertical direction) is the z direction. Hereinafter, it may be simply described as x direction, y direction, and z direction. Further, the tip side in the x direction is the front side.

FIG. 1 is a perspective view showing an embodiment of a railway vehicle provided with the boarding / alighting device of the present invention. The railroad vehicle 1 has a side structure 20 erected at both ends of the underframe (floor) 10 forming the floor in the y direction and a wife structure erected at both ends of the underframe (not shown) in the x direction. It is a hexahedral structure composed of a side structure 20 and a roof structure 30 mounted on the end of the wife structure in the z direction. The side structure 20 has a plurality of window portions 22 and a plurality of entrances / exits 24 for passengers and the like. The entrance / exit 24 can be provided with a side sliding door that allows passengers to get on and off.

The railroad vehicle 1 is a boarding / alighting device on a floor surface 10 (upper surface of the floor) between a seat 26 provided inside the side structure 20 along the x direction and a pair of entrances / exits 24 provided on the opposite side structure 20.

The boarding / alighting device 50 includes a slope 60 and a storage box 51 for storing the slope 60. The slope 60 can be pulled out from any one side of the storage box 51 in the y direction, and can be extended to the outside of the railroad vehicle 1 from the entrance / exit 24 on the pulled out side. While the railroad vehicle 1 is traveling, the slope 60 is stored in the storage box 51. When the railroad vehicle 1 stops at the station, the crew member or the station staff pulls out the slope 60 from the storage box 51 on the side of the opened entrance / exit 24, and the storage box 51 installed on the floor surface 10 in the railroad vehicle 1 It is possible to bridge the platform with the upper surface (hereinafter referred to as a platform) 2 by a slope 60.

The slope 60 includes a plurality of treads 62 that are continuously connected along the x direction. Among these plurality of tread plates 62, the tread plates 62 provided at both ends in the y direction include locking portions that engage with stoppers (for example, protrusions, not shown) inside the storage box 51. In this locking portion, the locking portion of the tread plate 62 is locked with the stopper of the storage box 51 when the slope 60 is to be pulled out to the maximum. As a result, even if the tread plate 62 is pulled out to the maximum on either side in the y direction (either the + y direction or the −y direction), the slope 60 is not separated from the storage box 51.

One end side (one tip 65) of the slope 60 pulled out from the storage box 51 abuts on the ground side, and the other end side (the other tip 65) of the slope 60 is inside the storage box 51. Located in. Thereby, while adjusting the withdrawal amount of the slope 60, it is possible to form a continuous tread surface from the upper surface of the storage box 51 to the ground side by the upper surface of the tread plate 62. The above-ground side refers to the upper surface of the platform 2 shown in FIGS. 1 and 7 and 8, the upper surface of the track bed (dog running surface) shown in FIG. 9, and the like.

FIG. 2 is a perspective view showing an embodiment of the boarding / alighting device of the present invention, and is a perspective view of a slope provided in a railroad vehicle and a storage box for accommodating the slope. FIG. 2 shows a state in which the slope 60 is stored in the storage box 51. In this case, each of the tread plates 62 is stored in the storage box 51 in a horizontal state.

The storage box 51 is a flat box whose z-direction dimension is extremely smaller than that of the x-direction and y-direction dimensions, and has a structure in which the built-in slope 60 can be pulled out to either side in the y-direction. The storage box 51 is provided with a plurality of upper panels 54 on the upper surface thereof, which cover the upper portion of the slope 60 and are installed side by side in the y direction. Note that FIG. 2 shows a state in which one upper panel 54 at the y-direction end of the storage box 51 is removed in order to depict the slope 60 housed in the storage box 51. In actual use, all top panels 54 are provided.

An outer edge portion having an inclined portion 52 formed is provided around the storage box 51, and covers the circumference of the slope 60. The inclined portion 52 constitutes a continuous smooth surface from the floor surface 10 to the upper surface of the upper panel 54. As a result, a wheelchair or a person can smoothly move between the floor surface 10 and the upper surface of the upper panel 54. The outer edge portion is formed by an outer edge portion along the y direction of the storage box 51 and an outer edge portion along the x direction of the storage box 51. On the other hand, the end portion of the storage box 51 in the y direction has an opening 53 on either side through which the slope 60 can pass. The opening 53 allows the slope 60 to be pulled out to either side in the y direction, and the slope 60 is pulled out from one end side in the y direction toward the entrance / exit 24 to be used. Further, a storage box 51 is formed in the vicinity of the openings 53 on both sides so that handles 65a provided at both ends of the slope 60 are arranged within reach from the openings 53. The openings 53 on both sides are arranged in the vicinity of the respective entrances 24.

FIG. 3 is a perspective view showing an example of the slope of the boarding / alighting device of the present invention, and FIG. 4 is a front view showing an example of the end portion of the slope of the boarding / alighting device of the present invention in the sleeper direction. FIG. 5 is a cross-sectional view along the sleeper direction showing an example of the slope and the slope connection portion of the boarding / alighting device of the present invention, and FIG. It is an enlarged cross-sectional view along.

As shown in FIGS. A honeycomb structure is formed by these. The slope 60 can be lightweight and have high rigidity due to this honeycomb structure. The first edge member 62a1 is provided at one end of the tread plate 62 in the y direction along the x direction, and the second edge member 62b1 is provided at the other end portion of the tread plate 62 in the y direction along the x direction. Be done. Further, the pair of third edge members 62e are provided at both ends of the tread plate 62 in the x direction along the y direction. Here, the peripheral edge portion of the tread plate 62 is formed by the first edge member 62a1, the second edge member 62b1, and the third edge member 62e. The core 62d is provided in a plane in the region surrounded by the peripheral edge portion. The pair of face plates 62c are provided so as to cover the peripheral edge portion and the upper surface and the lower surface of the core 62d. The face plate 62c does not have to cover the step mounting holes 62s and the handrail mounting holes 62h of the third edge member 62e.

In the example shown in FIG. 3, four tread plates 62 are connected side by side. For example, the dimension of the slope 60 composed of the four treads 62 in the y direction is formed to be slightly smaller than the dimension of the floor surface 10 in the y direction so that it can be arranged in the railway vehicle 1, and is, for example, about 2200 mm. Further, the dimension in the x direction is smaller than that of the entrance / exit 24, and is, for example, about 1000 mm.

As shown in FIG. 4, the tip portion 65 is provided at the end portion of the tread plate 62 located at both ends of the slope 60 in the y direction in the y direction. The length of the tip portion 65 in the x direction is the same as the length of the tread plate 62 in the x direction. The cross-sectional shape of the tip portion 65 intersecting in the x direction is a wedge shape (triangle as a whole) that tapers toward the end portion, and when placed on the upper surface of the home 2, the tread plate is formed from the upper surface of the home 2. A substantially continuous surface is formed up to the upper surface of 62. Further, at the central portion of the tip portion 65 in the x direction, a concave handle 65a used when pulling out the slope 60 from the storage box 51 is provided. Further, a plurality of rollers 62r are provided on the lower surface of the tread plate 62 so that the slope 60 can be easily pulled out from the storage box 51 in any one of the y directions (+ y direction or −y direction).

As shown in FIG. 5, in the slope 60, the first edge member 62a1 of one tread plate 62 and the second edge member 62b1 of the other adjacent tread plate 62 are rotatably hinged (hinge) 63 around the x-axis. They are connected in series via. The hinge 63 is attached to the lower side of one tread plate 62 and the other tread plate 62, and is provided so as to connect these tread plates. The center of rotation of the hinge 63 is at the boundary between one tread plate 62 and the other tread plate 62, and is located below these tread plates. Therefore, when the other tread plate 62 is rotated with respect to one tread plate 62, the distance between the first edge material 62a1 of one tread plate 62 and the second edge material 62b1 of the other tread plate 62 increases. growing. This makes it possible, for example, to form an angle between the horizontal tread plate 62 and the tread plate 62 having an inclination angle.

As shown in FIG. 5, the portions where one tread plate 62 and the other tread plate 62 are connected adjacent to each other are the first edge material 62a1 of one tread plate 62 and the second edge material of the other tread plate 62. 62b1 and 62b1 are connected by a hinge 63 in a facing manner. On the end surface r (the surface on the side facing the second edge material 62b1) of the first edge material 62a1 in the y direction, the second edge material 62b1 facing the entire width direction (x direction) of the slope 60 A first convex portion 62a2 projecting in the direction (−y direction) is provided. The end face s (the surface on the side facing the first edge member 62a1) of the second edge member 62b1 in the y direction has the first edge member 62a1 facing the entire width direction (x direction) of the slope 60. Is provided with a first recess 62b2 recessed in the opposite direction (−y direction).

As shown in more detail in FIG. 6, the first convex portion 62a2 has a base portion 101 protruding from the first edge member 62a1 and a tip portion 102 at the tip thereof. The base portion 101 is formed to have a certain thickness (z direction) dimension T1 between the first convex portion upper surface p1 and the first convex portion lower surface p2 substantially parallel to the xy plane. The tip portion 102 forms an inclined surface p3 on the upper portion so as to gradually decrease from the thickness (z direction) dimension T1 in the direction (−y direction) of the second edge member 62b1 facing from the base portion 101. Then, the cross-sectional shape cut in the xy plane is formed in a wedge shape as a whole.

The first recess 62b2 is a space having a constant thickness (z direction) dimension T2 formed between the upper surface q1 of the first recess and the lower surface q2 of the first recess substantially parallel to the xy plane. The dimension T2 of the first concave portion 62b2 is set slightly larger than the dimension T1 of the first convex portion 62a2. This dimensional difference is set within a range in which the first convex portion 62a2 is smoothly fitted to the first concave portion 62b2 and the effect of suppressing rattling is exhibited. The depth dimension of the first concave portion 62b2 in the y direction has a depth dimension into which the first convex portion 62a2 is inserted. Further, due to the configuration of the inclined surface p3, even when the adjacent tread plates 62 are angled, it is possible to prevent the first concave surface upper surface q1 from interfering with the first convex portion 62a2 and guide the fitting.

The end surface r of the first edge material 62a1 facing the end surface s of the second edge material 62b1 is an end surface r1 located above the first convex portion 62a2 (side in the + z direction) and below the first convex portion 62a2 (the side in the + z direction). It is divided into two, the end face r2 located on the side in the −z direction). Here, the end face r1 is cut out on the first edge member 62a1 side with respect to the end face r2 by the dimension δ in the y direction. As a result, when the force of F is applied from the upper side, the contact between the end face r1 and the end face s and the contact between the end portions of the adjacent face plates 62c on the upper side can be prevented, and these wears can be prevented.

When the slope 60 pulled out from the storage box 51 is bridged between the floor surface 10 (storage box 51) of the railway vehicle 1 and the upper surface of the platform 2 or the track bed 5 described later, the first edge material of the tread plate 62 is used. The first convex portion 62a2 of the 62a1 is inserted into the first concave portion 62b2 of the second edge member 62b1 of the adjacent tread plate 62. At this time, the upper surface p1 of the first convex portion of the first convex portion 62a2 abuts on the upper surface q1 of the first concave portion of the first concave portion 62b2 to support the load F, and the lower surface p2 of the first convex portion of the base 101 is the lower surface of the first concave portion. It abuts on q2 and supports the load F. As described above, since the load F is supported by the configuration of fitting the first convex portion 62a2 and the first concave portion 62b2, the hinge 63 does not bear the load F.

According to the above-described configuration, when the adjacent tread plate 62 is bridged between the railroad vehicle 1 and the platform 2 or the track bed 5 in an inclined manner, the adjacent tread plate 62 has a wedge shape of the hinge 63 and the first convex portion 62a2. The first convex portion 62a2 and the first concave portion 62b2 are fitted by being guided by the tip portion 102 of the above. As a result, rattling can be suppressed and a stronger and continuous flat surface can be maintained.

Therefore, even when the load of the passenger and the caregiver using the wheelchair acts on the upper surface of the slope 60, it is possible to suppress the occurrence of rattling at the connecting portion of the continuous tread plate 62. Further, since the hinge 63 does not bear the load F, it is possible to maintain higher strength reliability and suppress maintenance and replacement costs related to the hinge 63. Further, since the slope 60 can be stored in the storage box 51, the boarding / alighting device bridged between the vehicle and the ground side can be bridged between the vehicle and the ground side without requiring transportation to a predetermined boarding / alighting port.

FIG. 7 is a cross-sectional view showing an example of the slope of the boarding / alighting device of the present invention bridged between the railroad vehicle and the platform when the step between the railroad vehicle and the platform is small and intersects in the longitudinal direction of the railroad vehicle. FIG. 8 is a cross-sectional view of the railroad vehicle intersecting in the longitudinal direction showing an example of the slope of the boarding / alighting device of the present invention spanned between the railroad vehicle and the platform when the step between the railroad vehicle and the platform is large. be.

The height in the z direction from the upper surface (upper surface of the rail) of the crown of the rail 6 laid on the track laying 5 shown in FIGS. 7 and 8 to the floor surface 10 of the railway vehicle 1 (hereinafter referred to as the floor surface height dimension). ) Dimension H4 is approximately 1120 to 1240 mm. On the other hand, the heights H5 and H6 in the z direction from the upper surface of the rail 6 to the upper surface of the platform 2 (hereinafter referred to as the platform height dimension) are representative, although they differ slightly depending on the area where the railroad vehicle is provided. Two types of 920 mm and 1100 mm are the mainstream (although not many, there are examples of 760 mm). Furthermore, when the platform 2 is installed along a curved track, the distance from the platform 2 to the railroad car 1 changes in the horizontal plane, and the cant amount given to the track changes the railroad when the station is stopped. The floor surface 10 of the vehicle 1 may move up and down.

In the case shown in FIG. 7, assuming that the typical floor height dimension H4 is 1125 mm and the home height dimension H5 is 1100 mm, the difference H1 between the floor surface height dimension and the home height dimension is 25 mm. At this time, assuming that the slope 60 in which the four tread plates 62 are connected in series and the dimension in the y direction is about 2200 mm, the two tread plates 62 are pulled out from the storage box 51 to the platform 2 to form a slope portion. In this case, the angle D1 formed by the slope portion of the spanned slope 60 and the home 2 is about 8 °. The remaining two tread plates 62 that do not form a slope portion form a horizontal plane from the inside of the storage box 51 to the entrance / exit 24.

As shown in FIG. 8, assuming that the typical floor height dimension H4 is 1125 mm and the home height dimension H6 is 920 mm, the difference H2 between the floor surface height dimension and the home height dimension is 205 mm. At this time, assuming that the four tread plates 62 are connected in series and the slope 60 has a dimension in the y direction of about 2200 mm, the three tread plates 62 are pulled out from the storage box 51 to the platform 2 to form a slope portion. In this case, the angle D2 formed by the slope portion of the spanned slope 60 and the home 2 is about 10 °. The remaining one tread plate 62 that does not form a slope portion forms a horizontal plane from the inside of the storage box 51 to the entrance / exit 24.

Generally, a wheelchair can run on a slope up to an inclination angle of 5 °, and can travel on the slope relatively easily if the inclination angle is up to about 10 °, although it requires the help of a caregiver. Regardless of the height of the platform, if the two or three treads 62 constituting the slope 60 are pulled out from the storage box 51 and bridged to the platform 2, passengers in wheelchairs and the like can safely train. You can get on and off from vehicle 1 to platform 2.

As described above, the boarding / alighting device 50 does not require transportation to the boarding / alighting port for crossing the vehicle and the ground side (upper surface of the platform 2), and can cross the vehicle and the ground side. Further, by adjusting the number of tread plates 62 pulled out from the storage box 51, it is possible to form a slope portion having an appropriate inclination angle when a wheelchair or the like passes through. This makes it possible to deal with cases where the difference in height dimension between the floor surface 10 and the upper surface of the home 2 is different.

FIG. 9 is a perspective view showing an example of a case where the slope of the boarding / alighting device of the present invention is bridged between a railroad vehicle and a trackbed. FIG. 10 is a perspective view showing the slope, the steps to be installed on the slope, and the state before the handrail is attached when the slope of the boarding / alighting device of the present invention is bridged between the railroad vehicle and the trackbed. 11 is an enlarged front view showing an example of a fixed portion of a slope and a step of the boarding / alighting device of the present invention.

When a transportation failure occurs due to a large-scale power outage or railroad crossing, the crew disembarks passengers from the railroad vehicle 1 stopped between the stations to the trackbed 5 and guides them to evacuate to a safer place. In some cases. In this case, as shown in FIG. 9, the crew handles an emergency door cock (not shown) to open the entrance / exit 24, then pulls out the slope 60 from the storage box 51 and tracks from the floor surface 10 (storage box 51). The emergency stairs 61 can be assembled by spanning the slope 60 over the floor 5 and attaching the step 66 and the handrail 64.

As shown in FIG. 10, the emergency staircase 61 includes a plurality of treads 62 included in the slope 60, a plurality of steps (steps) 66 fixed to the treads 62, and a handrail 64 having a pillar fixed to the treads 62. Consists of. As described with reference to FIG. 3, the tread plate 62 of the slope 60 has a pair of third timbers 62e provided along the y direction. The third edge member 62e has a step mounting hole 62s into which the second convex portion 66c (FIG. 11) of the step 66 is inserted, and a handrail mounting hole 62h into which the convex portion (not shown) of the handrail pillar is inserted. Be prepared. In the example of FIG. 10, for one step plate 62, the step mounting holes 62s are provided in two places in the third edge material 62e on both sides, and the mounting holes 62h are provided in one place in each of the third edge material 62e on both sides. There is. Step 66 and the handrail 64 having pillars are kept in the crew room, equipment room, etc., for example, and they are taken out in an emergency and fixed to the slope 60 extending from the floor surface 10 of the railway vehicle 1 to the ground side. Then, the emergency staircase 61 can be configured.

As shown in FIG. 11, the step 66 has a step portion 66a forming a horizontal plane, an abutting portion 66b, and a second convex portion 66c. The contact portion 66b is formed on one end side of the step portion 66a in the y direction, and is formed along the third edge member 62e so as to abut on the third edge member 62e of the tread plate 62. The second convex portion 66c is formed so as to extend from the contact portion 66b and be inserted into the step mounting hole 62s. When the step 66 is fixed to the slope 60 extending from the floor surface 10 (storage box 51) of the railroad vehicle 1 to the trackbed 5, the contact portion 66b is brought into contact with the third edge member 62e of the step 66, and the first step 66 is fixed. 2 The convex portion 66c is inserted into the step mounting hole 62s and fixed. At this time, the contact portion 66b is formed at a predetermined angle with respect to the step portion 66a so that the step portion 66a is in a substantially horizontal posture.

As an example, assuming that the height dimension of a standard 50 kg rail is 153 mm and the height dimension from the rail upper surface of a typical railroad vehicle 1 to the floor surface 10 is 1125 mm, the height dimension from the track bed 5 to the floor surface of the railroad vehicle 1 is set. The height dimension H3 (FIG. 9) up to 10 is 1278 mm. Even if there is a height difference of more than 1 m from the floor surface of the railroad vehicle to the ground side in this way, the slope 60 is laid from the floor surface 10 to the trackbed 5, and the step 66 and the handrail 64 are fixed to the slope 60. The emergency staircase 61 can be configured. In the example shown in FIGS. 9 and 10, two steps 66 are attached to each of the three tread plates 62, for a total of six steps 66, and the height difference between the adjacent steps 66 may be an appropriate height. can. The remaining one tread plate 62 forms a horizontal plane from the inside of the storage box 51 to the entrance / exit 24. As described above, since the boarding / alighting device 50 is configured to pull out the slope 60 from the storage box 51, it is possible to form an emergency staircase without having to carry the boarding / alighting device to a predetermined boarding / alighting port.

The present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the described configurations. Further, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. Further, it is possible to add / delete / replace a part of the configuration of each embodiment with another configuration.

For example, in the above embodiment, it has been explained that the number of step plates 62 of the slope 60 can appropriately form a slope portion and an emergency staircase by showing an example of four sheets. However, in addition to this, the number of treads 62 can be changed to, for example, 3 or more and 4 or more depending on the situation. By increasing the number of tread plates 62, the amount of tread plates 62 taken out from the storage box 51 can be adjusted more, and the length of the slope portion can be changed more frequently.
