[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable slope that is bridged between an upper road surface and a lower road surface of a step so that a wheelchair or the like can pass through the step safely.
[0002]
[Prior art]
As a conventional portable slope, for example, as described in JP-A-2001-279898, a structure in which two slope plates are connected by a hinge and folded to be portable is known. Yes. Such a portable slope can be carried and carried, and when used, it opens on a flat surface and spans a step to form a running surface for a wheelchair. Japanese Patent Laid-Open No. 2002-97768 discloses a portable slope that can be folded and carried, and has a tapered portion that eliminates a step between the slope end and the ground plane.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional portable slope, if the entire length of the slope is set long so that it can be used even with a large step or several steps, the handling becomes inconvenient and the mass increases significantly. There was a risk that it would be difficult to carry.
[0004]
Therefore, for example, as described in Japanese Utility Model Laid-Open No. 1-177732, it is separated into two slope plates having a small width for weight reduction, and the slope plate is made to be a slide telescopic type in order to further improve portability. Slopes are also known, but when the slope plate is shrunk and carried, it was necessary to overlap the two slope plates and wrap them with a belt or the like, or put them in another storage bag.
[0005]
Further, as shown in FIG. 11 , the structure of the slide expansion / contraction type slope plate requires that the inner member 32 be accommodated in the outer member 31, and therefore the inner member 32 has dimensions in the width direction and height. In order to satisfy the rigidity, it is necessary to increase the outer dimension of the outer member 31 or to increase the thickness of the inner member 32. As a result, there is a problem that the total weight of the slope becomes heavy and the portability is remarkably deteriorated.
[0006]
Therefore, the present invention is made in the background of the above circumstances, wheelchairs and the like can pass through the steps safely, while ensuring the rigidity when a load is applied on the slope during use, such as a storage bag It is also a technical problem to provide a portable slope with excellent portability that is unnecessary.
[0007]
