Abstract

PURPOSE:To improve the reliability of a special step by providing a protective cover having the width wider than the step and extending from the lower por tion of a lower getting-on-and-off port to that of an upper getting-on-and-off port between the step groups on the go and return path sides. CONSTITUTION:A protective cover 9 is disposed which has the width larger than the lateral width of the return path side step group and extends from the lower portion of a lower getting-on-and off port 1A to the lower portion of an upper getting-on-and-off port 1B throughout the upper side of the return path side step group. This protective cover 9 has an angle section to introuduce in the direction of arrow A or sideways and expell outside dust and rain water intruding from between the go path side steps 3 or special steps 4, so that these intruding substances do not give any adverse effect to the special steps 4 on the return poth side. Thus, the rear side of the special step 4 for carrying a wheel chair is not affected by the dust and rain water so that troubles due to the intruding substances can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wheelchair escalator equipped with special steps for transporting wheelchairs.

[Conventional technology]

Recently, escalators capable of transporting wheelchairs have become popular, as known from Japanese Patent Application Laid-Open No. 60-223781. The main structure of this type of escalator is one to several special steps equipped with a road surface expansion device (usually with a special mechanical part and electrical system) that can transport wheelchairs in a group of endlessly connected steps. The system operates normally when there are only general users, and when a wheelchair user is present, the system operates exclusively for transporting wheelchair users.

[Problem that the invention seeks to solve]

The special steps of the above-mentioned wheelchair-accessible escalator are equipped with a road surface widening device of a special structure on the back side of the road surface, but there is no countermeasure against deterioration of reliability due to the intrusion of dust and rainwater into this special mechanism part.

This special step requires careful consideration because it has complex mechanical movements and an electrical system.

An object of the present invention is to provide a wheelchair-use escalator that can improve the reliability of special steps.

[Means for solving problems]

The above purpose is between the outgoing and returning steps of the step group.

A protective cover that is wider than the width of the step and extends from the bottom of the lower entrance to the bottom of the upper entrance can be installed.

[Effect]

The protective cover is configured to cover the return journey side where the special steps for transporting the wheelchair face in the opposite direction and the mechanical section and the electrical system section are exposed upward. For this reason, dust, rainwater, etc. that fall between the steps on the outbound side (including special steps) are blocked from entering the steps on the return side, especially the mechanical parts and electrical system parts of the special steps. This eliminates the inconvenient factors caused by intruders.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Figure 1 shows a wheelchair escalator 1 installed on support beams 2 at the bottom and top of a building, and is an example of a wheelchair escalator 1 equipped with a special step 4 for wheelchair transport among a large number of steps 3. It shows. Here, the special step 4 is equipped with a road surface expansion device 4a that combines a mechanical part and an electrical system part inside it, and is raised or lowered by a step driver 5 installed in the lower and upper machine rooms. be driven.

As shown in FIG. 2, the parapet 6, the main body frame 7 and the rail 8
It moves while being supported by strength members such as.

The return side is inverted with respect to the outbound side on which passengers ride, and the road surface expansion device 4a is exposed upward. However, in the embodiment of the present invention, a step is provided above the step group on the return side, which is wider than the width of this step group. The protective cover 9 is disposed over the width and the entire length from the lower part of the lower entrance LA to the lower part of the upper entrance IB. This protective cover 9 has a chevron shape, and guides dust and rainwater that enters between the steps 3 on the outbound side or between the special steps 4 in the direction of arrows A or B to remove them to the outside. The structure is such that intruding objects do not adversely affect the special step 4 on the return trip.

By doing this, the back side of the special step 4 for transporting a wheelchair is not affected by dust or rainwater, and troubles caused by intruding objects can be prevented.

〔Effect of the invention〕

According to the present invention, it is possible to obtain a wheelchair-use escalator that can improve the reliability of special steps for transporting wheelchairs.
