Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheelchair-equipped escalator, and more particularly to a wheelchair-equipped escalator capable of transporting a large wheelchair user.

[0002]

2. Description of the Related Art As a conventional technique relating to an escalator capable of carrying not only ordinary passengers but also wheelchair users, there is known a technique disclosed in Japanese Patent Laid-Open No. 61-130195.

[0003] In this prior art, the tread surface rises and expands only when the wheelchair is transported, so that a wheelchair mounting surface for about two normal tread surfaces can be secured, and a wheel stop is provided before and after the mounting surface. Is provided.

As another related conventional technique, for example, a technique disclosed in Japanese Utility Model Laid-Open No. 62-98683 is known.

This prior art relates to an entrance / exit of an elevator, and in order to prevent the wheels of the wheelchair from falling into the gap between the elevator car and the landing side, from the car (or landing) side. It is to install a crossing board on the other side so that it can be taken in and out.

[0006]

In the prior art, when a large wheelchair such as an electric wheelchair tries to get on the escalator, a part of the wheelchair protrudes from the horizontal wheelchair mounting surface for about two treads, In front of it (the user of the wheelchair rides in the same direction regardless of whether he / she goes up or down), he / she also gets in by using the tread surface of a normal step in front of the escalator.

In the prior art, the wheelchair mounting surface is approximately twice as large as the normal tread surface, and when the wheelchair is boarded, the wheelchair mounting surface and the normal step in front of the wheelchair mounting surface are substantially the same. Although it is possible to configure a flat surface, when an electric wheelchair or the like tries to board using a normal front step, there is a wheel stop on the front side of the wheelchair mounting surface, so the wheel of the wheelchair is used as this wheel stop. There is a problem that it is difficult to get in because of being disturbed and the front tread surface of a normal step cannot be fully utilized. Further, in the above-mentioned conventional technology, since a mechanism portion for expanding the tread is provided under the step constituting the wheelchair mounting surface, a gap is generated between the wheelchair mounting surface and the normal step in front of it. However, there is a problem that it poses a danger when getting into a wheelchair.

Further, the prior art relating to the entrance / exit of the elevator is required only when getting on and off the elevator, and is not required during operation as in the present invention, and a space for getting in a wheelchair. The present invention is different from the present invention in that it is not for ensuring the above.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a wheelchair-combined escalator which allows a large wheelchair such as an electric wheelchair to easily get in and to fully utilize the tread surface of a normal step in front. To provide.

[0010]

According to the present invention, the object is to eliminate the wheel stop on the front (upper) side of the step for mounting the wheelchair, which is formed by raising and expanding the tread surface only when the wheelchair is transported. This is achieved by providing a slidable spacer for closing a gap generated between the wheelchair mounting surface and the tread surface of the front (upper) side step.

[0011]

[Function] The front (upper) side wheel stopper of the wheelchair-mounted step formed by the rise and expansion of the tread is eliminated, and a gap is created between the wheelchair mounting surface and the front (upper) side step tread. By providing a slidable spacer that closes the front tread surface, it is possible to put the front wheel of the wheelchair on the tread surface.
A tread that is three times the size of a normal tread can be used for wheelchair transport as a whole. The present invention provides
Even large electric wheelchairs can be safely transported.
