Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wheelchair boarding / alighting device for a bus.
[0002]
[Prior art]
To make it easy for a wheelchair to get on and off a low-floor bus, the slope board is usually stored under the floor of the entrance and is pulled out from under the floor to form a slope between the floor edge of the entrance and the ground. Such a device is provided, for example, in Japanese Utility Model Laid-Open No. 3-129531.
[0003]
[Problems to be solved by the invention]
In use, the slope plate needs to be long enough to bridge between the floor edge of the entrance / exit and the ground. On the other hand, it is necessary to store it in a limited space when storing it under the floor. is there. For this purpose, the slope plate is folded in two or three. Incidentally, also in the above-mentioned Japanese Utility Model Laid-Open No. 3-129531, an auxiliary lamp board that hangs on the floor edge of the entrance / exit is pivotally attached to one end of the main lamp board so as to be foldable on the upper surface of the lamp board.
[0004]
In such a foldable slope plate, the side edges of the elevation are provided on both sides of the main slope plate, thereby preventing the wheelchair from being removed. In order to allow folding on the upper surface of the slope plate, it is not possible to form the side edges of the elevation on both sides. Therefore, when the wheelchair passes the auxiliary slope plate, there is a risk of wheel removal, and it is necessary to prevent this.
[0005]
An object of the present invention is to provide a wheelchair boarding / alighting device that prevents a wheelchair from being removed when a wheelchair gets on or off the bus.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is a wheelchair boarding / alighting device provided at a boarding / alighting entrance of a bus, and a flat sub-slope plate is provided at one end of a main slope plate provided with side edges on both sides. It consists of a slope plate body that is folded on the surface of the plate and unfolds and is pivotally attached to the floor edge of the entrance / exit to be suspended by a suspension plate, and moves forward and backward in the direction of the entrance / exit under the floor of the entrance / exit The front end of the slide arm provided is pivotally attached to the main slope plate so that the slope plate main body can be stored in a storage chamber provided under the floor, and when the sub slope plate is deployed on the side edge of the main slope plate The flange member that forms the elevation wall along the side of the sub slope plate, the engagement piece that engages the front end of the sub slope plate at both ends, and the back surface of the sub slope plate in the width direction of the sub slope plate fixed on both ends of the through the strip of the secondary slope plate It is characterized in that it has folding and deployable pivotally attached to follow the Ritatami and deployment operations.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a floor of a low-floor bus, and 2 is a boarding / alighting step. A storage chamber 3 extends in the lower part of the floor 1 in parallel to the floor surface in the entrance / exit direction, and a slide arm 4 having a roller 5 is guided to be movable in the entrance / exit direction.
[0008]
6 is a slope plate body. As shown in FIG. 2, the slope plate body 6 includes a main slope plate 7 having side edges 7a on both sides (FIG. 2 shows only one side), and one end of the main slope plate 7 (when tilted) A flat auxiliary slope plate 8 is folded on the surface of the main slope plate 7 by a hinge 9 on the upper end side, and is connected to the main slope plate 7 so that it can be unfolded on the same plane. A hanging plate 10 is provided on the edge of the floor surface on the upper end). Further, an auxiliary slope plate 11 for eliminating the step between the lower end of the main slope plate 7 and the ground 13 when the slope plate main body 6 is inclined at the other end (the side that becomes the lower end when inclined) of the main slope plate 7. Are hingedly connected to the upper surface of the main slope plate 7 and the same plane as the main slope plate 7 in a foldable manner.
[0009]
In the present invention, as shown in FIG. 2, a flange member 14 is formed on the side edge 7a of the main slope plate 7 to form an elevation wall along the side of the secondary slope plate 8 when the secondary slope plate 8 is unfolded. Following the folding and unfolding operation of the slope plate 8, it is pivotally attached so that it can be folded and unfolded.
[0010]
One end of the flange member 14 is pivotally attached to a vertical surface on the inner side of the side edge 7 a of the main slope plate 7 by a hinge 15. Although one of the flange members 14 is omitted in FIG. 2, a pair of flange members 14 are pivotally mounted on both sides of the main slope plate 7. The structure in which the pair of flange members 14 are folded and unfolded following the folding and unfolding operation of the sub-slope plate 8 is such that the back plate of the sub-slope plate 8 is passed through the strip plate 16 in the width direction of the sub-slope plate 8. The flange member 14 is fixed to both ends of the band plate 16, and the engagement pieces 17 that are engaged with the surface end portions of the auxiliary slope plate 8 are provided at both ends of the band plate 16. The flange member 14 has a length that forms an elevation wall over the entire length of the side of the auxiliary slope plate 8 when the auxiliary slope plate 8 is unfolded. Is desirable.
[0011]
Since the present invention has the structure as described above, the flange member 14 is folded on the surface of the main slope plate 7 together with the auxiliary slope plate 8 when the slope plate body 6 is stored. This is because when the secondary slope plate 8 is folded on the surface of the main slope plate 7, the engagement pieces 17 at both ends of the strip plate 16 engage with the surface end portions of the secondary slope plate 8 so as to be substantially integrated with the strip plate 16. The flange member 14 is caused to follow the folding of the auxiliary slope plate 8.
[0012]
The folded flange member 14 is unfolded by lifting the band plate 16 passing through the back surface of the sub slope plate 8 in the width direction of the sub slope plate 8 when the sub slope plate 8 is unfolded. The flange member 14 that is substantially integral with the belt plate 16 is made to follow the development of the auxiliary slope plate 8.
[0013]
Therefore, as shown in FIGS. 1 and 2, when the slope plate body 6 is inclined and bridged between the floor edge of the entrance / exit and the ground 13, the pair of flange members 14 have the tips at the edges of the floor 1. A vertical wall is formed over the entire length of the side of the auxiliary slope plate 8 so as to be prevented from being removed by the flange member 14 when the wheelchair passes the auxiliary slope plate 8.
[0014]
Here, if the elevation wall is integrally formed at the side end of the secondary slope plate 8, when the secondary slope plate 8 is folded on the surface of the primary slope plate 7, the back surface of the secondary slope plate 8 is the side of the primary slope plate 7. The height of the storage chamber 3 must be increased by increasing the height of the edge 7a. However, the auxiliary slope plate 8 and the flange member 14 are formed separately, so that the auxiliary slope plate 8 is formed into the main slope plate 7. It is possible to make the storage chamber 3 into a small space by being folded compactly so as to contact the surface.
[0015]
【The invention's effect】
As described above, according to the present invention, in the slope plate body of the folding structure having the secondary slope plate that cannot integrally form the side edges of the vertical surfaces on both sides, the secondary slope plate is developed on the side edge of the primary slope plate. Sometimes, the wheelchair has a simple structure in which a flange member that forms an elevation wall along the side of the secondary slope plate is pivotally attached so that it can be folded and deployed following the folding and deployment operations of the secondary slope plate. When passing, the safety of preventing wheel removal is ensured by the flange member.
