Description

  The present invention relates to a slope device that is stored and mounted in a vehicle, and is deployed and used in a slope shape outside the vehicle when getting on and off a wheelchair or the like.

As a slope device for a vehicle, a device in which a slope is divided into a plurality of parts and connected by a folding structure or a slide structure is known.
Japanese Utility Model Laid-Open No. 56-69546 has a second road plate that is refractably connected to an end edge of the first road plate via a hinge, and the first road plate has a telescopic shape. Disclose what you have.
However, as shown in FIG. 8 (a), when the grip 125 is pulled to expand the road plates 104 and 105 from the state where the device 110 is stood and stored in the vehicle loading platform 102, the road as shown in FIG. 8 (b). The plates 104 and 105 are opened with the hinge 107 as a rotation center.
Therefore, as shown in FIG. 8C, it is unstable until the end surfaces of the road plates 104 and 105 on the hinge 107 side come into contact with each other, and the operator is standing on the side of the road plates 104 and 105 and moving upward. Therefore, it is necessary to further incline while opening the road plates 104 and 105 in this unstable posture, the operation posture is unreasonable, and the operation itself is difficult.
Further, the operation posture in which the nests 104a and 105a are slid and extended on the road plate 104 and the tip of the road plate is grounded becomes unstable.
For this reason, the shock absorber which reduces an inclination speed is provided and the cost is high.
Furthermore, the load applied to the slope may concentrate on the hinge 107.

An object of the present invention is to provide a vehicle slope device that can absorb water.

A slope device for a vehicle according to the present invention includes a tilt slope connected to a vehicle side, a slide slope slidably connected to the tilt slope, and a folding slope that can be folded back on a deployment side of the slide slope. There is a support leg that contacts the ground when using the slope, and there is an operating lever for sliding operation in the vicinity of the connecting part of the slide slope and the folding slope. It is characterized by being grounded when in use.
Here, the position of the operating lever is the vicinity of the connecting portion between the slide slope and the folding slope because the operating lever is provided at a position where the sliding slope can be operated with the folding slope folded on the slide slope. Yes, it may be attached to the rear surface of the slide slope on the development side, or may be attached to a position that is the rear surface of the folded slope connecting portion side when deployed.

The slide slope is slidable within a predetermined range from a state where it overlaps the tilt slope along the slope surface of the tilt slope.
The tilt slope rises when the base end side is pivotally attached to the vehicle and pivotally attached to the vehicle when the slope is stored. However, the tilt slope may be slidable along the floor of the vehicle.
In the present invention, the slide slope can be developed by holding the operation lever provided on the side opposite to the base end portion of the slide slope, turning the tilting slope to the outside of the vehicle, and pulling it as it is.
The folding slope is folded and overlapped with the slide slope when the vehicle is stored, so that the folding slope is supported on the slide slope in a state where the tilting slope is tilted or stood.
As a result, the tilting slope can be tilted and erected, and the slide slope can be slid while the folded slope is folded over the slide slope.

  The vehicle slope device has a direct object of getting on and off a wheelchair or the like on the vehicle, but the invention according to claim 4 has also responded to the recent needs of outdoor leisure, with the slide slope being pulled out horizontally. It becomes a table.

In the vehicle slope device according to claim 1, when the slope is unfolded, the tilting slope is held by the operation lever provided at the tip of the slide slope, and the slide slope is extended as it is, and the support leg is grounded. And open the folding slope from the folded state.
At the time of storage, the folding slope is folded back on the slide slope, the operation lever is operated to contract the slide slope, and the tilting slope is operated upright.
Therefore, the expansion and storage operations are simple and easy to perform.
Since the present invention is divided into three slopes, the total length of the slope can be set longer, the slope angle becomes gradual, and when stored upright at the rear of the vehicle, the height during storage can be lowered, and the rear visibility Will improve.
In addition, since the load is applied even at the tip of the slide slope, the load resistance is large, and the return slope is rotated and deployed from the tip of the slide slope.

  In the vehicle slope device according to claim 2, since it has a derailing prevention flange portion, for example, it is possible to prevent a wheelchair or the like from derailing from the slope surface, and the derailing prevention flange portion provides a slide structure. Because it is built, the load-bearing capacity is large, and getting on and off the wheelchair is smooth.

  In the vehicle slope device according to the third aspect, since the operation lever of the folding slope is provided outside the flange portion for preventing the wheel removal, the operation lever does not hinder the traveling of the wheelchair or the like.

  In the vehicle slope device according to the fourth aspect, since the bench leg is storably provided on the back surface of the slide slope, it can be used for multipurpose purposes such as a table.
