Description

The present invention relates to an auxiliary member extending to a lower ground contact portion or an upper hook portion of a slope member that spans a step portion of a building or a vehicle entrance.

A slope member that forms a slope surface is used when a wheelchair gets on and off a vehicle or when passing through a stepped portion of a building or the like.
In this case, if a portable slope member is used, the inclination angle of the slope changes depending on the height of the floor of the vehicle and the size of the step of the building.
Considering portability, there is a limit to the length of the slope member. For example, as shown in FIG. 6, the wheelchair 1b has a footrest 1b before the wheel 1a of the wheelchair 1 rides on the lower end portion 4 of the slope member 2. Since the mounting portion 1c and the like of the wheelchair interfere with the slope surface 2a of the slope member and the wheelchair cannot travel as it is, it is necessary to lift the front side of the wheelchair.

Further, if there is a convex portion such as a deck edge or a rail member such as a window frame rail on a stepped portion of a building, it may be difficult to bridge the slope member as it is.

Patent Document 1 discloses a technique for extending a guide slope portion that forms a second slope having a smaller inclination angle than the first slope.
However, the second slope disclosed in the same publication is formed on the first slope portion, has no raising effect on the lower end side of the first slope portion, and cannot cope with various different step portions.

Further, the hooking auxiliary member is effective in avoiding an interfering object on the hill side of the stepped portion.

An example in which the grounding auxiliary member according to the present invention is connected to the lower end of the main slope member, (a) and (b) show the running state of the wheelchair. A first structural example of the grounding auxiliary member is shown. A second structural example of the grounding auxiliary member is shown. An example of improvement when the main slope member is bridged is shown. The second improvement example when the main slope member is bridged is shown. The problems of the conventional slope member are shown.

Hereinafter, auxiliary members of the main slope member according to the present invention will be described with reference to the drawings.
In the example shown in FIG. 1, when the portable main slope member 2 is bridged between the hill H such as the rising stile of the building and the ground contact surface G such as the entrance, the main slope member 2 is hung on the hill H. This is an example in which the hanging portion 3 on the upper side of the main slope member 2 is hung and the grounding auxiliary member 10 according to the present invention is connected to the lower end portion 4 of the main slope member 2.
An enlarged view of the grounding auxiliary member 10 is shown in FIG.
In FIG. 2, (a) is before connection and (b) is after connection.

The grounding auxiliary member 10 is an example made of an extruded aluminum alloy material, and has a slope portion 11 and a connecting portion 12.
On the main slope member 2 side of the connecting portion 12, there is a connecting portion 13 made of a soft material made of a rubber material.
The connecting portion 13 has a main lip 13a and an auxiliary lip 13b into which the tip end portion of the lower end portion 4 of the main slope member 2 is inserted.
The lower surface side of the connecting portion 12 has a leg portion 12a on the connecting portion side and a leg portion 12b on the slope portion 11 side, and the upper portion of the leg portion 12a and the insertion portion 12c provided in the connecting portion 12 are used. The insertion lip 13c of the connecting portion 13 is inserted and held.
A grounding member 11a, 112a, 112b made of a soft material, for example, a rubber material, is attached to the tip of the slope portion 11 of the grounding auxiliary member 10 and the lower part of the leg portions 12a, 12b of the connecting portion 12.
As a result, as shown in FIG. 1, the slope portion 11 of the grounding auxiliary member 10 is extended from the lower end portion 4 of the main slope member 2, and the lower end portion 4 is raised by the connecting portion 12. Due to the effect of loosening the inclination angle of the main slope member 2, the wheel 1a rides along the slope surface without the mounting portion 1c of the footrest 1b of the wheelchair 1 interfering with the slope surface.
In this embodiment, the upper surface of the connecting portion 12 is substantially horizontal, but the connecting portion 12 may have a gentler slope than the slope portion 11.
At this time, since the connecting portion 13 is made of a soft material, it is possible to absorb the variation in the inclination angle of the main slope member 2.
Such a grounding auxiliary member 10 can be carried while being connected to various slope members.

An example is shown in which the grounding auxiliary member 10 shown in FIG. 3 is a mounting portion 14 on which the lower end portion 4 of the main slope member can be mounted as it is, instead of the connecting portion 13.
The mounting portion 14 is made of a soft material such as a rubber material, and has a connecting portion 14d with the connecting portion 12 and a mounting surface 14a whose surface is slightly lowered in a stepped shape from the connecting portion 14d.
The mounting portion 14 is an example in which the leg portion 14c is connected to the leg portion 12a of the connecting portion and the grounding member 14b is provided.
Such a mounting type grounding auxiliary member 10 has a high degree of freedom in that it can be used only by mounting the lower end portion 4 of the main slope member 2.
For example, as shown in FIG. 4, it can also be used as a hooking auxiliary member 20 on which the hooking portion 3 of the main slope member 2 is placed.
FIG. 4 shows that when the convex portion H1 is present on the hill side as shown in (a), it is effective to bridge the hook portion 3 so as to avoid the convex portion H1.
In this case, in order to prevent the inclination angle of the main slope member 2 from becoming steep, it is preferable to use the grounding auxiliary member 10 at the same time as shown in FIG. 4 (b).

In FIG. 5, there is a sweep-out window rail H2 on the hill side, and various rails such as an entrance sliding door rail and a windshield sliding door rail are present on the grounding side, and it is difficult to bridge the main slope member 2 as it is. In some cases, as shown in FIG. 5, the auxiliary member according to the present invention can be used for raising the height to avoid those obstacles.
