Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of steps in an escalator for wheelchairs.

[Conventional technology]

The depth of normal escalator steps is approximately 400 mm, which is sufficient for general passengers to use, but when used by a physically disabled person who uses a wheelchair, etc. The downside was that it was too big to use the escalator.

For this reason, an escalator is constructed in which the tread of any step is movable in the depth direction (back and forth), and the tread is pulled out toward the rear wheels to substantially increase the depth of the tread only when a person with a disability uses the escalator. Patent application 1986-114635 (Japanese patent application No. 1983-6583), patent application No. 58-120493 (Japanese patent application No. 1987-12487), and patent application No. 1983
-198057 (Japanese Unexamined Patent Publication No. 60-93089), the applicant recently proposed.

By the way, if you just pull out the tread,
As shown in FIG. 1, at the position where passengers get on and off the wheelchair, there is a difference in level between the wheelchair step 1 and the lower normal step 2 adjacent thereto.
In the above proposal, as shown in FIG. 2, an inclined plate 3 is provided at the rear end of the footboard 4 and is rotatably movable in conjunction with a movement mechanism of the footboard via a shaft 3a.

That is, although a description of parts not directly related to the present invention will be omitted, a rack 5 is provided on the back side of the tread plate 4 of the step 1 for the handicapped, and a pinion 6 that engages with the rack 5 is provided below the tread plate 4 to create a rack pinion. In addition to configuring the mechanism, a chain gear 7 is provided at one end of the shaft 3a, and a chain gear 8 is rotatably provided on one side of the front end of the tread plate 4, that is, on the same side as the chain gear 7. and a rack 1 which meshes with a pinion 9 to form a rack and pinion mechanism.
When the pinion 6 is rotated counterclockwise by winding the chain 11 on which the chain 11 is fixed, the rack 10 and the pinion 9 engage with each other in accordance with the movement of the treadle 4a rearward. Chain 11 is connected to the second
Inclined plate 3 that moves in the direction of the arrow in figure a.
Rotate approximately 180° clockwise around shaft 3a to rotate the second
The state shown in FIG. b and FIG. 3 is obtained.

[Problem that the invention attempts to solve]

However, although the provision of the inclined plate 3 certainly makes it easier for a wheelchair to get onto the step 1 for the disabled, due to reasons such as the wheelchair passenger's inexperience and the narrow width of the inclined plate 3, is inclined plate 3
There was a risk that the wheels would swerve and fall off, and safety was still inadequate.

The present invention was developed in view of the above points, and an object of the present invention is to provide an escalator step that can be used extremely safely even by passengers in wheelchairs.

[Means for solving problems]

In the present invention, at least one step of a plurality of steps constituting an escalator is configured such that a treadle is movable in the front and back direction, and the rear end of the treadle is covered with the treadle to form a part of the treadle. In an escalator step having a rotatably inclined plate, a convex member is provided on the left and right sides of a surface of the inclined plate that covers the tread, and the tread plate is provided with a hole for accommodating the convex member. This is what we are trying to do.

[Effect]

With the above configuration, the protrusions will appear on the inclined plate only when a wheelchair passenger uses the escalator.
It can prevent the wheelchair from falling off.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

In FIG. 4, the same reference numerals as in FIGS. 1 to 3 indicate the same thing, and 23 is located at the rear end of a tread plate 24, which will be described later, and forms a part of the tread plate 24 by covering it. The inclined plate according to the present invention is provided with a convex member 23a that is one step higher than the central portion at both left and right ends of the surface of the inclined plate that covers the tread plate 24. 24 is a treadle which is also constructed according to the present invention and is movable;
A hole 24a shaped to normally accommodate the convex member 23a of the inclined plate 23 rotatably attached to the rear end.
It has on both left and right ends. If the width of the convex member 23a of the inclined plate 23 is made as small as possible than the width of the wheels of the wheelchair, even if there is a hole 24a in the tread 24, there is no risk that the wheels of the wheelchair will fall into the hole 24a, so it is safe. be.

Incidentally, if the hole 24a is not provided with a hole bottom and can be pushed through, sand, dirt, etc. will not accumulate in the hole 24a, so the member 23a can always be stored when necessary, and the step can be returned to the normal step state without fail. is desirable. Another idea is to make the convex member 23a a brightly colored material that is clearly different from the step board 24 to draw attention when getting into the vehicle.

[Effect of idea]

As described above, according to this invention, the escalator steps are normally exactly the same as normal escalators, but when a wheelchair passenger uses the escalator, protrusions appear at the boarding area of the tread to prevent the wheel from slipping off, resulting in escalator steps that allow even a single wheelchair passenger to get on and off extremely safely.

Furthermore, if the movable treadle and the rotatable inclined plate are linked together, the steps can be changed from a general passenger step state to a wheelchair step state in a short period of time. Can be transported efficiently.
