Japanese Unexamined Patent Publication No. 3-016872 JP-A-2002-347607

Patent Document 1 intends that passengers do not fall into the gap between the inside of the vehicle and the platform, and does not study wheelchairs. That is, the step between the inside of the vehicle and the auxiliary step is not considered.

In Patent Document 2, although the filling of the gap from the inside of the vehicle to the platform and the interpolation of the step are taken into consideration, only a small inclined portion is provided for the step from the slope to the inside of the vehicle. Such an inclined portion is not a problem when the wheelchair enters the vehicle from the outside of the vehicle, but it is a step that must be overcome when the wheelchair goes out of the vehicle from the inside of the vehicle.

The present invention has been conceived in view of the above problems, and when getting on and off in a wheelchair, it is possible to get on and off without overcoming a step regardless of the direction from the inside of the vehicle to the outside of the vehicle or from the outside of the vehicle to the inside of the vehicle. It provides a slope.

More specifically, the railway vehicle slope device according to the present invention is

It is characterized by having a rotation mechanism 15 for rotating the vehicle outer slope 10 and the vehicle inner slope 20.

The railcar slope device according to the present invention has two slopes, one is the outside slope of the vehicle from the inside of the vehicle to the outside of the vehicle, and the other is the inside slope of the vehicle from the side entrance / exit inside the vehicle to the center of the vehicle body. Not only when getting in the wheelchair, but also when getting off the wheelchair from inside the vehicle to the outside of the vehicle, it is possible to move without feeling a step.

Further, by providing a sun plate at the joint between the vehicle outer slope and the vehicle inner slope, the gap between the vehicle outer slope and the vehicle inner slope can be smoothly moved by the wheelchair. In addition, even if the step between the platform and the floor of the passenger cabin changes from station to station, the inside and outside of the vehicle can be connected by a slope.

The drawings of the railroad vehicle slope device according to the present invention will be shown and described below. The following description exemplifies one embodiment and one embodiment of the present invention, and the present invention is not limited to the following description. The following description can be modified without departing from the spirit of the present invention.

FIG. 1 shows a state in which the slope device 1 of the railway vehicle according to the present invention is deployed. Although the doors for getting on and off the vehicle 2 and the side structure are omitted, a housing 4 (indicated by a dotted line in FIG. 1A) for accommodating the slope device 1 is provided in the vehicle 2.

The slope device 1 connects steps and gaps from the vehicle 2 to the platform 3 with a gentle slope, and can secure a passage path that is easy for people with wheelchairs or walking obstacles to pass. The slope device 1 according to the present invention includes a vehicle outer slope 10, a vehicle outer shaft 12, a vehicle inner slope 20, a vehicle inner shaft 22, a sun plate 30, and a rotation mechanism 15.

<Shaft>
FIG. 1A shows a perspective view in which the slope device 1 is developed. Further, FIG. 1 (b) shows a cross-sectional view taken along the line AA. Note that FIG. 2 (b) shows a partially enlarged view of FIG. 1 (b). The vehicle outer shaft 12 and the vehicle inner shaft 22 are installed adjacent to each other in parallel. When deployed, these two shafts are installed in the vehicle 2 at a position parallel to the entrance / exit door of the railway vehicle.

<Slope>
The vehicle outer slope 10 is a rectangular plate material, which is made of a lightweight material with little deformation. For example, an aluminum plate having a reinforce structure formed of ribs or the like can be preferably used. Further, reinforced plastic or the like may be used. The vehicle outer slope 10 has a length of 10 L corresponding to the distance from the inside of the vehicle 2 to the platform 3. Specifically, about 500 mm to 1200 mm is suitable.

The vehicle inner slope 20 can also be formed with the same structure as the vehicle outer slope 10. However, since the vehicle inner slope 20 may have a smooth slope from the highest point when the vehicle outer slope 10 is deployed to the floor 2a of the vehicle 2, the length 20L is the vehicle outer slope 10. About half of the length of 10L is sufficient.

Both the width 10W of the vehicle outer slope 10 and the width 20W of the vehicle inner slope 20 need to have a width that allows a wheelchair to pass through with a margin. Specifically, it is preferably about 700 mm to 1000 mm. Both the vehicle outer slope 10 and the vehicle inner slope 20 may have ribs 10r and ribs 20r for preventing derailment formed at both ends in the width direction.

The side of the vehicle outer slope 10 that collapses on the platform 3 is referred to as the tip side 10a of the vehicle outer slope 10, and the side remaining in the vehicle 2 is referred to as the shaft side 10b. Further, the side of the vehicle inner slope 20 on the side that falls into the vehicle 2 is referred to as the tip side 20a of the vehicle inner slope 20, and the side close to the entrance / exit is referred to as the shaft side 20b.

<Coupling of shaft and slope>
FIG. 2A is a cross-sectional view of the vehicle inner slope 20. The shaft side 20b of the vehicle inner slope 20 has a flange 20f through which the vehicle inner shaft 22 penetrates in the width direction thereof. The flange 20f is formed so as to protrude from the back surface 20d of the vehicle inner slope 20 toward the back surface 20d. The vehicle inner shaft 22 serves as a pivot on the shaft side 20b side of the vehicle inner slope 20.

Similarly, a flange 10f (not shown) is also formed on the shaft side 10b of the vehicle outer slope 10, and the vehicle outer shaft 12 penetrates the flange 10f. Therefore, similarly to the vehicle inner slope 20, the vehicle outer shaft 12 is a pivot on the axis side 10b side of the vehicle outer slope 10.

As a result, the vehicle outer slope 10 is rotatably fixed with the vehicle outer shaft 12 as the pivot, and the vehicle inner slope 20 is rotatably fixed with the vehicle inner shaft 22 as the pivot. The vehicle outer slope 10 and the vehicle inner slope 20 can freely rotate around the vehicle outer shaft 12 and the vehicle inner shaft 22.

<Sun board>
The sun plate 30 has a length of 30 L that closes between the vehicle outer slope 10 and the vehicle inner slope 20. The width 30W (not shown) may be substantially the same as the width 10W of the vehicle outer slope 10 and the width 20W of the vehicle inner slope 20 (see FIG. 1).

Further, the sun plate 30 is connected to the shaft side 10b of the vehicle outer slope 10 or the shaft side 20b of the vehicle inner slope 20 by a belt hinge 32. Here, an example of being connected to the vehicle inner slope 20 is shown. The belt hinge 32 is a hinge system called a so-called string hinge. The principle is shown in FIG.

FIG. 3D shows a state in which the vehicle inner slope 20 and the sun plate 30 are connected by half of the belt hinge 32. The belt hinge 32 shows a state in which a strip-shaped belt 32a is passed from the back surface 20d of the vehicle inner slope 20 to the front surface 30u of the sun plate 30 and adhered to the back surface 20d of the vehicle inner slope 20 and the front surface 20u of the sun plate 30, respectively. ..

The actual belt hinge 32 further passes another strip-shaped belt 32b from the front surface 20u of the vehicle inner slope 20 to the back surface 30d of the sun plate 30 and adheres to the front surface 20u of the vehicle inner slope 20 and the back surface 30d of the sun plate 30, respectively. do. The belt hinge 32 thus formed is a vehicle when both the vehicle inner slope 20 and the sun plate 30 rotate in the upright direction (FIG. 3 (a)) and become flat (FIG. 3 (b)). Even when the inner slope 20 is lowered (FIG. 3 (c)), the movement is not restricted. Further, it is not bulky, and it becomes easy to cover the gap between the shaft side 20b (see FIG. 2B) of the vehicle inner slope 20 and the sun plate 30. The belt hinge 32 may be replaced with a folding screen hinge.

With reference to FIG. 2B again, a taper 30t is formed on the side of the sun plate 30 not connected by the belt hinge 32 from the front to the back. Due to this taper 30t, as the vehicle outer slope 10 is lifted, it slides up along the surface 10u and is maintained upright between the upright vehicle outer slope 10 and the vehicle inner slope 20.

<Rotation mechanism>
The slope device 1 is provided with a rotation mechanism 15 (see FIG. 4) for rotating the vehicle outer slope 10 and the vehicle inner slope 20. The rotation mechanism 15 rotates the vehicle outer slope 10 from the upright state to the horizontal state with the shaft side 10b as the rotation center side, and rotates the vehicle inner slope 20 from the upright state to the horizontal state with the shaft side 20b as the rotation center side. ..

A vehicle outer arm 14 is fixed to the vehicle outer shaft 12. Further, a vehicle inner arm 24 is fixed to the vehicle inner shaft 22. The vehicle outer arm 14 is arranged on the back surface 10d side of the vehicle outer slope 10, and the vehicle inner arm 24 is arranged on the back surface 20d side of the vehicle inner slope 20.

Further, the vehicle outer shaft 12 and the vehicle inner shaft 22 are connected by a synchronous gear 16. Here, the synchronous gear 16 refers to a gear in which two spur gears having the same diameter and the same number of teeth are meshed with each other. Further, a motor (not shown) for rotating the vehicle outer shaft 12 is provided.

The rotation mechanism 15 includes a vehicle outer shaft 12 and a vehicle inner shaft 22 connected by a synchronous gear 16, a vehicle outer arm 14 fixed to the vehicle outer shaft 12, and a vehicle inner arm 24 fixed to the vehicle inner shaft 22. And a motor that rotates the vehicle outer shaft 12 or the vehicle inner shaft 22.

<Wheel part>
One ends of the vehicle outer shaft 12 and the vehicle inner shaft 22 are put together to form a wheel portion 40 (see FIG. 1). The wheel portion 40 allows the slope device 1 to advance from the inside of the housing 4 in a folded state of the vehicle outer slope 10 and the vehicle inner slope 20, or to move to be housed in the housing 4.

<Operation>
FIG. 4 shows a state in which the vehicle outer slope 10 and the vehicle inner slope 20 are folded upright. When not in use, it is housed in a housing 4 placed next to the entrance / exit in such a folded state.

When used, the slope device 1 is activated by a switch on the inside of the vehicle 2 or the outside of the vehicle 2 (not shown). The slope device 1 may be activated by wireless remote control by a crew member from the driver's cab. When activated, the slope device 1 extends from the housing 4 in parallel with the entrance / exit, with the wheel portion 40 at the head.

Next, the rotation mechanism 15 is driven. When the vehicle outer shaft 12 is rotated by a motor (not shown), the vehicle inner shaft 22 is also rotated by the synchronous gear 16 (see FIG. 2B). When the vehicle outer shaft 12 rotates, the vehicle outer arm 14 rotates so as to fall toward the platform 3. When the vehicle outer arm 14 rotates, the vehicle outer slope 10 also rotates toward the outside of the vehicle 2. On the other hand, when the vehicle inner arm 24 rotates toward the inside of the vehicle 2, the vehicle inner slope 20 also rotates. FIG. 5 shows a state in which the vehicle outer arm 14 and the vehicle inner arm 24 are rotated by about 45 ° from the vertical direction.

FIG. 6 shows a state in which the tip side 10a of the vehicle outer slope 10 is in contact with the platform 3 and the tip side 20a of the vehicle inner slope 20 is in contact with the floor 2a of the vehicle 2. When the vehicle outer slope 10 of the sun plate 30 is inclined, the taper 30t (see FIG. 2B) is inclined along the surface 10u of the vehicle outer slope 10 (see FIG. 5), and the vehicle outer slope 10 and the vehicle inner slope 10 are inclined. When the deployment of 20 is completed, the vehicle is arranged at a position that closes the gap between the vehicle outer slope 10 and the vehicle inner slope 20.

The vehicle outer arm 14 and the vehicle inner arm 24 rotate further than horizontally. Therefore, as shown in FIG. 1, the vehicle outer slope 10 can be rotated until the tip end side 10a of the vehicle outer arm 14 comes into contact with the platform 3 even if the platform 3 is lower than the floor 2a of the vehicle 2.

In this way, when the vehicle outer slope 10 and the vehicle inner slope 20 come into contact with the platform 3 and the floor 2a, respectively, the development of the slope is completed. When the deployment of the slope is completed, the user passes through the vehicle outer slope 10 and the vehicle inner slope 20 and goes back and forth between the platform 3 and the vehicle 2.

The wheelchair can move smoothly because there is no step in the passage of the wheelchair when entering the vehicle 2 from the platform 3 or getting off the vehicle 2 from the inside of the vehicle 2. Further, since the sun plate 30 closes the gap between the shaft side 10b of the vehicle outer slope 10 and the shaft side 20b of the vehicle inner slope 20, the movement from the vehicle outer slope 10 to the vehicle inner slope 20 also feels a step. You can move smoothly without any problems.

When the use is finished, the slope is folded by a switch (not shown) arranged inside or outside the vehicle 2. See FIG. 7. First, the vehicle outer shaft 12 is rotated by a motor, and the vehicle inner shaft 22 is also rotated by the synchronous gear 16. By this rotation, the vehicle outer arm 14 and the vehicle inner arm 24 rotate in a direction in which they stand upright in the vertical direction.

The vehicle outer arm 14 and the vehicle inner arm 24 abut on the vehicle outer slope 10 and the vehicle inner slope 20, and push up the vehicle outer slope 10 and the vehicle inner slope 20 in an upright direction.

At this time, the vehicle outer shaft 12 and the vehicle inner shaft 22, which are the pivots of the vehicle outer slope 10 and the vehicle inner slope 20, are arranged at positions deviated from the bottom surface of each slope. Therefore, the vehicle outer slope 10 and the vehicle inner slope 20 draw a trajectory such that the distance LM between the shaft side 10b and the shaft side 20b approaches as the vehicle inner slope 20 approaches the upright direction.

As a result, in the sun plate 30 arranged between the vehicle outer slope 10 and the vehicle inner slope 20, the side on which the taper 30t not connected by the belt hinge 32 (see FIG. 3) is formed is the vehicle outer slope 10. It slides up along the surface 10u (see FIG. 7 (b)) and is maintained in a substantially upright state between the upright vehicle outer slope 10 and the vehicle inner slope 20 (see FIG. 7 (c)).

As described above, the railway vehicle slope device 1 according to the present invention can secure a passage having a smooth slope without a step between the inside of the vehicle 2 and the platform 3, and is from the inside of the vehicle 2 to the outside of the vehicle 2. It is possible to easily get on and off the wheelchair or a person who has difficulty in walking in either direction, from the outside of the vehicle 2 to the inside of the vehicle 2.

The present invention can be suitably used for railway vehicles. It can also be used when getting on and off a ship or a large vehicle.
