Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope device which has a plurality of slidably connected slope portions and which allows a slope to be lowered from the vehicle to the ground to allow a wheelchair or the like to be taken in and out.

[0002]

2. Description of the Related Art As a conventional vehicle slope device, there is known a foldable slope device which can be easily mounted on and off a wheelchair and can be mounted on the rear part of the vehicle, as disclosed in Japanese Patent Laid-Open No. 10-86739. ing. As a structure of such a slope device, a rolled material made of an aluminum alloy is generally used for the floor member of the slope portion, and both side portions of the floor member are bent to prevent the wheelchair wheels from getting over. ing.

[0003]

However, in the above-described conventional folding type slope device, when the slope device is not used, the slope device is mounted on the rear part of the vehicle in a folded state. The thickness of the slope part, including the wheel prevention part, requires a mounting space that is stacked by the number of folded slope parts.
This was against the demand for smaller vehicles.

Further, a person who operates the take-in and take-out of the slope device needs to go around the side surface of the slope device and hold the handle on the side surface of the slope part with one hand while supporting the slope part with the other hand. Could be a complicated and burdensome task. Therefore, an electric slope device has been proposed, but it requires a complicated device, which leads to an increase in cost.

Further, as described in Japanese Patent Application Laid-Open No. 2001-1836, there is known a slide type vehicle slope device for pulling out an auxiliary plate to form a slope. When this slope device is not used, the slope main body (back door lower) has a built-in auxiliary plate and is mounted on the vehicle, so the mounting space has been reduced, but also in terms of design. It was difficult to provide a wheel removal prevention part. Furthermore, foreign matter such as sand and dust may enter and accumulate in the space where the auxiliary plate of the slope body is built in, which may reduce the function of the roller attached to the auxiliary plate.

[0006] Therefore, the present invention has been made in view of the above-mentioned circumstances, and the workability of an operator is improved, and the slope portion is provided with a derailment prevention portion. It is a technical object to provide a slope device for a vehicle that can reduce the mounting space on the vehicle when in use.

[0007]

In order to solve the above problems, the present invention has a plurality of slope portions slidably connected to each other, and one slope portion is provided with another slope portion. In a slope device that can be installed in the passenger compartment with the slope part stored, and that allows the wheelchair to be taken in and out from the vehicle in the deployed state, each slope part extends in the slope width direction. A plurality of floor members and rail members that extend in the slide direction at both ends in the width direction of the slope to prevent wheelchair derailment are configured, and are arranged in a deployed state on the first slope portion located on the vehicle side. When the second slope portion adjacent to the first slope portion is stored, the two second rails configured in the second slope portion are provided inside the two first rail members configured in the first slope portion. Together member is disposed, the first
A sliding member and a cushioning member for smooth sliding are provided between the rail member and the second rail member in a direction perpendicular to the sliding direction, and the floor of each of the first slope portion and the second slope portion is provided. A stopper mechanism is provided for restricting the position of the second slope portion in the sliding direction with respect to the first slope portion in the deployed state and the stored state by engaging the engaging portions integrally formed with the member with each other. And a slope device for a vehicle.

According to the slope device of the present invention, the first
When the second slope portion is stored in the slope portion, the two second rail members configured in the second slope portion are arranged inside the two first rail members configured in the first slope portion. Therefore, the thickness of the slope device when mounted on a vehicle can be reduced. Further, since the sliding member and the cushioning member are provided between the first rail member and the second rail member, smooth sliding with less rattling and catching is possible, and further, a stopper mechanism is provided. As a result, excessive sliding in the deployed state and the stored state can be prevented, so that the workability of the operator can be improved.

Preferably, as described in claim 2, a handle which is rotatable about an axis parallel to the slope width direction is provided at the ground side end in the slide direction in the deployed state and at the center in the slope width direction. It is desirable to be equipped. According to this, it becomes possible for the operator to move the slope device in and out with one hand, and the workability is further improved, so that the load on the operator can be reduced.

When the slope portion 20 is stored, the first slope portion 10
Inside the two first rail members 11 configured in
Since the two second rail members 21 configured in the second slope portion 20 are arranged, the thickness of the slope device 1 when mounted on a vehicle can be reduced. Further, since the sliding members 16, 17, 26, 27 and the cushioning members 15, 25 are provided between the first rail member 10 and the second rail member 20, a smooth slide with less rattling and catching can be achieved. It is possible. Furthermore, since the engaging portion 12a engages with the engaging portion 22a or the engaging portion 24a, excessive sliding in the deployed state and the stored state is prevented, so that the workability of the operator can be improved. .

Furthermore, the shaft 3 parallel to the slope width direction
Since the handle 31 rotatable about 2 is provided, it is possible for an operator to put in and take out the slope device with one hand, and there is no danger of pinching a finger between the handle 31 and the ground. Since the workability is improved, the load on the operator can be reduced. Further, since the handle 31 is provided at the central portion in the width direction of the slope, it does not interfere with the wheel of the wheelchair.
