Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a slope board for getting on and off a vehicle between a floor of a vehicle and a passage outside the vehicle. 2. Description of the Related Art Generally, in a vehicle such as a local bus in the city, the floor inside the vehicle is set at a higher position than the passage outside the vehicle. Therefore, one or more steps are provided at the entrance of such a vehicle. By using this step, the passenger or the like gets on or off the vehicle, so that the safety of the passenger or the like when getting on or off can be ensured. However, when the vehicle is a shuttle bus to various facilities such as facilities for the physically handicapped and nursing homes, some passengers use so-called wheelchairs, in which steps cannot be used effectively. Such a wheelchair user needs to have an attendant get on and off the bus, and there is a problem that a wheelchair user cannot use the bus without an attendant. [0003] In order to solve this problem, it is known to provide a vehicle with a slope plate that is bridged between the floor of the vehicle and a passage outside the vehicle. It is required to be relatively small in terms of space. For this reason, as shown in FIG. 4, a slope board 2 for getting on and off having a main slope board 3 and an auxiliary slope board 4 has been proposed (Japanese Utility Model Laid-Open No. 3-129331). The main slope plate 3 of the entrance / exit slope plate 2 has a pair of first flanges 3a formed on both sides thereof, and a first flange 3a provided on a slider 6 slidably provided in the vehicle width direction under the floor of the entrance / exit. One end of 3a is pivoted. The main slope plate 3 is stored under the floor when not in use, protrudes to the side of the vehicle when in use, and has the other end groundable. On the other hand, the auxiliary slope plate 4 has a base end pivotally attached to one end of the main slope plate 3 by a plurality of hinges 7 and is folded in the retracted state of the main slope plate 3 when not in use and overlaps the main slope plate 3. The storage space is relatively small. Conversely, when the main slope plate 3 protrudes during use, the auxiliary slope plate 4
Is developed so that the front end overlaps the floor surface of the entrance / exit of the vehicle, so that the step between one end of the main slope plate 3 and the side end of the floor 1 can be eliminated. With the ramp board 2 configured as described above, the wheelchair user can easily get on and off the bus by himself or with the assistance of his / her assistant by using the ramp board 2 for getting on and off. ing. However, a plurality of hinges 7 are required.
In the conventional ramp board 2 for getting on and off, the base end of the auxiliary slope board 4 is pivotally connected to one end of the main slope board 3 by using a plurality of hinges 7 because the auxiliary slope board 4 is folded when not in use.
When the auxiliary slope plate 4 is unfolded during use, the hinges 7 appear on the slope plate to form irregularities, and there is a problem that the smoothness of the boarding surface is lost.
In addition, it is preferable that the slope plate 2 for getting on and off which is stored under the floor when not in use and protrudes to the side of the vehicle when used is as light as possible in consideration of its easy handling.
However, in the conventional slope plate 2 for getting on and off which is pivotally connected by a plurality of hinges 7, if the plate thickness is reduced in order to promote the reduction in weight, the required rigidity cannot be secured. There is a problem that the slope plate 2 is bent when the user rides. In order to solve this problem, it is necessary to use a hinge extending over the entire width of the slope plate. However, since the hinge itself is relatively expensive, there is a problem that the unit price of the slope plate for getting on and off is increased. SUMMARY OF THE INVENTION An object of the present invention is to provide a slope board for getting on and off which can secure the required rigidity of the slope board with a relatively simple configuration and can promote a reduction in the weight of the slope board.
