Abstract

PROBLEM TO BE SOLVED: To easily get a wheelchair on and off a vehicle by projecting a slope plate stored in the floor part to the outside of a vehicle to be substantially flush with the upper surface of the floor part by a first driving means, and inclining the floor part downward in the projecting direction of the slope plate by a second driving means. SOLUTION: Normally, for example, during running of a vehicle, a slope plate 7 is stored in a case 5 to be made flush with the floor surface 3 of the floor part 4. In getting a wheelchair on and off a vehicle, take-up shafts 8, 9 are normally rotated through a worm, a pinion mechanism 11 and a cable 12 by the operation of a motor 10, and with the displacement of the cable 12, the slope plate 7 is projected to the outside of the vehicle along slide groove. After that, a cable or a chain 15 is guided by each pulley 14 to be displaced by the drive of each hydraulic cylinder 13, so that the case 5 is turned downward on each pin 16 by its dead load, and the rear end of the slope plate 7 is brought into contact with the upper surface of the foot walk or the ground 21 to form a slope by the floor surface 3 of the floor part 4 and the slope plate 7.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for facilitating getting on and off a vehicle such as a bus with a wheelchair or the like.

[0002]

2. Description of the Related Art A conventional vehicle getting-on / off device that facilitates getting on / off by a wheelchair includes a lift system in which a base plate on which a wheelchair is placed is brought up and down in contact with the rear of a vehicle body, and a slope plate folded several times. There is a folding slope system that opens gradually from the rear of the car body or from the side of the car body so that the slope of the entire slope is gentle, but the former has the disadvantage that the operation itself is easy, but the time required for getting on and off is long. Yes, the latter can make the time required for getting on and off relatively short, but the operation of opening and closing the slope plate is troublesome and time consuming. There was a disadvantage.

[0003] Further, as disclosed in Japanese Patent Publication No. 61-14015, an automatic overhanging slope system in which a ramp for getting on and off in a wheelchair is formed by pulling out or retracting a ramp from a vehicle body is also known. This method is easy to operate, and when there is an appropriate sidewalk higher than the roadway, the slope of the slope becomes gentler, making it easier to get on and off with a wheelchair. Becomes relatively steep,
In fact, a fundamental problem that made it very difficult to get on and off a wheelchair was inevitable.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a device which facilitates getting on and off a vehicle by a wheelchair or the like and which is easy to operate.

[0005]

Therefore, a vehicle getting-on / off device according to the present invention has a slope plate housed in a floor portion in contact with a vehicle getting-in / out port, and the slope plate is formed so that the slope plate is substantially flush with the upper surface of the floor portion. The first to let the vehicle in and out to form
There is provided a driving means and a second driving means for inclining the floor downward in a direction in which the slope plate projects.

Accordingly, the slope plate accommodated in the floor is extended outwardly of the vehicle by the first driving means so as to form substantially the same plane as the upper surface of the floor, and the slope plate is formed by the second driving means. If the floor is inclined downward in the direction of the overhang, a relatively long continuous slope is formed by the upper surface of the floor and the slope plate. The slope connecting the entrance / exit and the ground is relatively gentle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention shown in the drawings will be described below. In FIG. 1, a rear door 1 provided at the rear end of a vehicle such as a small bus or the like is widely opened to form an entrance 2 at the rear of the vehicle, and a floor 4 having a floor surface 3 is provided in contact with the entrance 2. Have been.

[0010] As shown in FIG. 2, the floor 4 is removed from the floor 3, and slide grooves 6, 6 are attached to the upper left and right ends of the case 5, respectively. The left and right ends of the slope plate 7 are slidably fitted to each other, and the front winding shaft 8, which extends in the vehicle width direction and is rotatably supported in the case 5, includes a motor 10, a worm, and a pinion mechanism 11. And a cable 12 is hung on a winding shaft 8 and a rear winding shaft 9 which also extends in the vehicle width direction in the case 5 and is rotatably supported. The cable 12 is connected to the front end of the lower surface.

Further, as shown in FIG. 3 with the floor surface 3 of the floor portion 4 removed, hydraulic cylinders 13, 13 and pulleys 14, 14 are fixed to the vehicle body on the left and right sides of the case 5, respectively. A cable or chain 15 having one end connected to each hydraulic cylinder 13 is hung on each pulley 14, and the other end of each cable or chain 15 is locked to the left and right rear ends of the case 5, respectively. 5 is pivotally supported on the vehicle body by pins 16 extending in the vehicle width direction at the left and right front ends, respectively.

In the above apparatus, the slope plate 7 is housed in the case 5 as shown in FIG. 4 (A) at normal times such as when the vehicle is running, and the floor 3 of the floor 4 is higher than the other floor 20 in the vehicle. However, when the user gets on and off the vehicle in a wheelchair or the like, the winding shafts 8 and 9 are rotated forward by the operation of the motor 10 via the worm, the pinion mechanism 11 and the cable 12, and FIG.
As shown in (B), the slope plate 7 projects along the slide groove 6 toward the rear of the vehicle with the displacement of the cable 12.

Thereafter, the cable or chain 15 is extended rearward of the vehicle by driving the respective hydraulic cylinders 13 so that the cable or chain 15 is
As shown in FIG. 4C, the case 5 pivots downward about the respective pins 16 by the weight of the floor 4 and the rear end of the slope plate 7 is placed on the sidewalk upper surface or the ground 21. Abut.

In this case, since the floor 4 itself is inclined downward and the slope is formed by both the floor surface 3 of the floor 4 and the slope plate 7, there is no sidewalk higher than the roadway so that the ground 21 is not provided. Even if the slope is relatively lower than the vehicle floor surface 20, the slope of the slope is always relatively gentle, and the height of the floor surface 3 of the floor portion 4 differs from the upper surface of the slope plate 7 by the thickness of the floor surface 3. Only steps are performed, and there are almost no steps. Therefore, it is possible to easily get on and off with a wheelchair using the slope.

The above-mentioned driving of the motor 10, the hydraulic cylinder 13 and the like can be automatically performed as appropriate.
By driving the above device in the reverse direction, the floor 4 can be automatically returned to the original horizontal state, and the slope plate 7 can be automatically stored in the case 5 of the floor 4. Is simple, and it is easy to operate the device quickly, which is very convenient in practice.

In the above embodiment, the order of the overhang of the slope plate and the inclination of the floor is set in the front and rear order.
If necessary, these can be performed almost simultaneously.If there is sufficient space on the floor inside the car, such as a large bus, go out from the entrance on the side of the car to the outside in the vehicle width direction. It goes without saying that the floor portion may be inclined downward so that the slope plate projects outward from the inside of the floor portion in the same vehicle width direction.

[0015]

According to the vehicle getting-on / off device of the present invention, a slope plate protruding from the inside of the floor to the outside of the vehicle is provided.
A relatively long continuous slope is formed by the upper surface of the floor inclined downward, and when the tip of the slope plate contacts the ground, the slope of the slope connecting the vehicle entrance and the ground is relatively gentle. Therefore, it is possible to easily get on and off with a wheelchair using this slope, and it is possible to perform the operation by each driving means easily and quickly, which is very convenient.
