Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boarding / alighting assist device which eliminates a step between a floor surface of a railway vehicle and a platform to facilitate movement of a wheelchair or the like.

[0002]

2. Description of the Related Art A railway car is described in Article 192 (passenger entrance / exit) of Article 6 of the Ordinance of the Six Laws of the Railway, "The difference between the height of the floor or step and the height of the platform is as small as possible. In this case, the height of the floor or step shall be equal to or higher than the height of the platform, unless there is a risk that it will not hinder the safe and smooth entry and exit of the passenger. " Usually, the floor is higher than the platform, so that it is not possible to ride in a wheelchair as it is due to this step. In the case of curves, the distance between the platform edge and vehicles spreads, and there was a danger of falling onto the track from there.

As a method for solving such a problem, Japanese Patent Application Laid-Open No. 2-212257 has been proposed. This patent is
While the vehicle is stopped, the tread is raised to the same height as the platform to prevent the vehicle from falling. However, the step between the floor of the vehicle and the platform has not been eliminated. Japanese Unexamined Patent Publication No. Hei 7-108926 discloses a method in which a step plate is inclined between a floor surface of a vehicle and a platform surface to eliminate a step. However, there was a problem that the installation cost was very high. In addition, in the case of this method, both the tilting device for tilting the step plate and the forward / backward driving device are required, and there is a problem that the device becomes complicated.

[0004]

By the way, in recent years, the number of accidents of falling from the station platform has increased, and as a countermeasure, the number of stations having a platform door installed has increased. According to the present invention, by forming the device integrally with the home door device, the gap between the vehicle entrance and the platform can be almost eliminated without performing any exaggerated construction on the platform as described above, and moreover, the device can be used in a wheelchair. It is an object of the present invention to provide a device capable of getting on and off between a platform and the inside of a vehicle by itself.

[0005]

SUMMARY OF THE INVENTION The present invention focuses on the fact that there is always a step between the floor of a vehicle and the platform as described above, and that the number of stations where platform doors are installed has increased in recent years. It was done by using both.

In order to achieve the above-mentioned object, according to the present invention, a storage portion is provided at a position on a platform corresponding to an entrance of a stopped vehicle, provided in the storage portion,
A step of moving toward the entrance when the vehicle is stopped and retreating into the storage part when the vehicle is absent; a storage device comprising a slope plate provided between the storage part upper surface and a platform surface; a home door for opening and closing the storage device; A door pocket for accommodating the home door at the time of getting on and off the vehicle, and a step-driving drive device provided in the door pocket constitutes a getting-on / off assistance device.

Further, as described in claim 2, a part of the driving device for the step drive provided in the door pocket is distributed and installed in the storage device, thereby minimizing the size increase on the door pocket side. A similar effect is obtained. Hereinafter, details of the present invention will be described with reference to the drawings.

[0008]

FIG. 1 shows an embodiment of the present invention, in which a vehicle and a platform are viewed from above.
FIG. 2 is a view from section AA of FIG. In the figure, reference numeral 1 denotes a platform, 2 denotes a step which advances toward an entrance when the vehicle stops and retreats when the vehicle departs, and shows a state in which the steps approach the vehicle. Reference numeral 3 denotes a storage device for storing the step 2, which includes a storage portion 3a and a slope plate 3b for eliminating a step between the upper surface of the storage portion and the platform surface. 5 is a door pocket for a home door, and 6 is a home door. FIG. 1 shows a state in which the door is closed. Reference numeral 7 denotes a drive device storage portion provided on the door pocket for driving the step, 8 denotes a vehicle, 9 denotes a floor of the vehicle, and 10 denotes a door on the vehicle side.

The present invention has been made in view of the fact that there is always a step between the floor surface of the vehicle and the platform surface and that there is a home door near the vehicle. The drive unit, which is housed in a step between the floor surface and the platform surface, and does not enter the space, inflates a part of the door pocket and stores the door pocket therein, thereby eliminating the need for extensive construction of the platform.

FIG. 6 is a conceptual diagram showing an example of a step driving device, where 2 is a step. 20 is an electric motor, 21 is a pulley, 22a, 23a, 24a, 25a is step 2
Is a pulley for advancing Step 2 in the A direction, and 26b and 27b are pulleys for advancing Step 2 in the B direction. Now, when the electric motor 20 is rotated and the rope is pulled in the direction A, step 2 proceeds in the direction A by the action of the pulleys 22a to 25a. When the motor 20 is rotated in the reverse direction, the rope advances in the direction B, and the step 2 advances in the direction B.

FIG. 3 shows the step portion viewed from the lateral direction, 2 shows a state where the step has moved forward (toward the vehicle), and FIG. 4 shows a state where step 2 has retreated. 1
Reference numeral 1 denotes a guide fixed to the driving device storage section 7 for step driving of the door pocket, and is provided on both left and right sides of the step. 12
Is a roller attached to the guide. FIG. 5 is a view of FIG. 3 viewed from the direction of arrow A (left half). The plate rising from both ends of step 2 is further bent in the horizontal direction, and the tip thereof is positioned between the guide 11 and the roller 12. The guide can be easily moved in the front-rear direction by entering, and the step can be kept substantially horizontal by being supported by the upper inner surface of the guide and the rollers. As another embodiment of the present invention, a rack is provided on the step side,
A pinion may be provided on the fixed side, and the pinion may be rotated by an electric motor.

Next, claim 2 will be described. The dimensions between the vehicle floor and the platform surface are relatively large,
If a part of the power source can be stored in the storage device, and the motor that drives the driving force does not enter the storage device,
An electric motor or the like is housed in the drive device housing part provided in the door pocket, and the direction of power is changed using a belt or a bevel gear if necessary,
It is an embodiment of the present invention that the step is moved forward and backward in the storage device 3 using, for example, a ball screw. According to another embodiment of the present invention, when the height of the storage device can be made relatively high, the electric motor that is the source of the driving force is also stored in the storage device 3 and one of the driving mechanisms constituting the drive device. The parts, for example, the guide 11 and the roller 12 may be provided in the drive device storage part 7.

In FIG. 1, the storage device of the step drive device is inflated to the platform tip side (vehicle side) of the door pocket, but inflating to the opposite side (gate side) is also an example of the present invention. Of course. Further, it is an embodiment of the present invention to inflate both the platform tip side (vehicle side) and the opposite side (gate entrance side) of the door pocket. In FIG. 6, the drive source is provided on only one side of the step.
It is needless to say that a method in which drive sources are provided on both left and right sides by a rack and pinion method and the left and right drive sources are synchronously controlled is also an example of the present invention. Although FIGS. 1 and 2 illustrate the case where the home door is a double door, it goes without saying that the present invention can be applied to a single door.

As described above, according to the present invention, when the vehicle is stopped, the steps first approach the vehicle, and then the home door is opened. It is also easily possible to provide an electrical interlock mechanism so that the home door closes first and then the steps retract into the storage device.

[0015]

The present invention focuses on the fact that there is always a step between the floor surface of the vehicle and the platform surface, and a step portion is stored in the difference, and a step portion is stored if the driving portion cannot be stored in the difference. Is housed in a partially inflated state using the door pocket of the home door. In this way, the platform does not dig down and the drive mechanism simply moves horizontally in the front-rear direction. Therefore, the present invention does not require both the tilting device and the forward / backward driving device unlike Japanese Patent Application Laid-Open No. Hei 7-108926, and enables the wheelchair to move on its own by a relatively simple method.
