As a structure of the slope of such a slope device, a rolled material made of an aluminum alloy is generally used for a floor member of the slope, and both side portions of the floor member are bent to prevent the wheel of a wheelchair from getting over. Further, the rigidity of the floor member when a load is applied on the slope is ensured by the thickness of the rolled material or reinforcement by another member.

[0003]

However, in the above-mentioned conventional slope device, it is necessary to increase the thickness of the slope floor member in order to satisfy the rigidity of the slope, and as a result, the mass of the slope device is reduced. There is a problem that the operation of expanding and storing the slope becomes complicated.

[0004] There is also a method in which another plate material is bonded and reinforced by welding, rivets, or the like from the back side of the floor member to a portion where strength is required. However, the number of steps for bonding another member increases, and the manufacturing cost is also reduced. There was a problem of disadvantage.

Therefore, the present invention makes it possible to smoothly operate the slope when deploying and storing the slope without reducing the rigidity of the floor member when a load is applied on the slope.
It is an object to provide an inexpensive vehicle slope device.

[0006]

Means for solving the above-mentioned problems according to the present invention is to provide a slope device which allows a slope to be lowered from a vehicle to the ground so that a wheelchair or the like can be taken in and out. A reinforcing member is provided on the member, which is provided with a groove extending in a direction intersecting the direction in which the slope is developed, and which is provided with a fitting portion capable of fitting into the groove.

[0007] According to the above means, when the groove provided on the floor member and the fitting portion of the reinforcing member are fitted to each other, the floor member bends due to the load applied on the slope. Can also be suppressed. Therefore, the rigidity of the floor member can be ensured without increasing the wall thickness of the floor member or firmly joining the floor member and the reinforcing member by welding, rivets, or the like.
As a result, the operation at the time of unfolding and storing the slope can be performed smoothly, and a totally lightweight and inexpensive slope device can be provided.

As shown in FIGS. 3 and 4, the front slope 4 has side rails 9 extending in the direction in which the slope 3 is developed, a plurality of floor members 6 extending in the vertical direction of the side rails 9, and reinforcing members. Similarly, the rear slope 5 includes a side rail 9, a plurality of floor members 6 and 7, and a reinforcing member 8. Both ends of the floor members 6 and 7 and the reinforcing member 8 in the longitudinal direction are fitted into grooves extending in the longitudinal direction of the side rail 9 and fixed by welding or screwing or the like.

As shown in FIG. 5, a groove 6c comprising two flanges 6a and 6b extending in the longitudinal direction is provided on the surface of the floor member 6 located on the back side of the slope device 3. The fitting portion 8a of the reinforcing member 8 is fitted to 6c. Similarly, as shown in FIG. 6, the floor member 7 is also provided with a groove 7c composed of two flanges 7a and 7b, and the fitting portion 8a of the reinforcing member 8 is fitted in the groove 7c.

The floor members 6 and 7 are formed by extrusion molding of an aluminum alloy or a synthetic resin, respectively, and the surfaces of the floor members 6 and 7 located on the surface side of the slope device 3 are provided with non-slip extending parallel to the longitudinal direction. 6d,
7d are provided integrally. The reinforcing member 8 is made of a steel material and is configured to satisfy desired rigidity of the front slope 4 and the rear slope 5 together with the floor members 6 and 7.

According to the above-described embodiment, the fitting portions 8a of the reinforcing members 8 with the grooves 6c, 7c provided in the floor members 6, 7 are provided.
Are fitted to each other, so that the floor members 6 and 7 tend to bend due to the load applied to the slope device 3.
Can also be suppressed. That is, when a load is applied to the floor member 6, the center of the cross-section is bent downward in FIG. Although the force acts, the fitting portion 8a of the reinforcing member 8 fitted in the groove 6c
Is suppressed by In addition, a force that tends to deform outward in the deployment direction of the slope device 3 also acts on the fitting portion 8a, but is suppressed by the flange 6a.

Therefore, the front side slope 4 and the rear side slope 4 do not have to be thickened, and the floor members 6, 7 and the reinforcing member are not firmly joined by welding or rivets. 5 can be secured. As a result, the slope device 3 can be manufactured lightweight and inexpensively, and the operation at the time of deployment and storage can be performed smoothly.

FIG. 7 shows a modification of the present invention.
One fitting portion 18a is fitted in the groove 16c of the floor member 16, and the other fitting portion 18b is fitted in the groove 17c of the floor member 17 adjacent to the floor member 16.
