Abstract

PURPOSE:To prevent people from accidents between a step and a skirt guard by providing an approximately 'U' formed side part tooth piece having a slanted part for opening the entrance part of the space of the skirt guard at each side end part of a cleat and/or a riser. CONSTITUTION:A side part tooth piece 1B provided on each side part of the own cleat 1A of a step 1 is formed in such a way as to cover the outer face 1aa, the apical part 1bb and the inner face 1cc of the cleat 1a at the side end, and fixedly provided at a cleat groove part 1dd by adhesive 1C, vis, and the like. A normal small space (g) is further formed in the direction of decreasing a space G spread between the step 1 and a skirt guard 2, and a slanted part 1ff is provided at the apical part of the space (g) in such a way as to open the entrance part of the space (g) and painted in yellow different from the color painted on the step 1. In addition, this slanted part 1ff is provided at the higher part than the apical part 1bb of the cleat 1A, and the opening part of the entrance part is formed wider than the space (g) in width.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a passenger conveyor such as an escalator or an electric guideway, and in particular to a passenger conveyor such as an escalator or an electric guideway, and in particular, a conveyor for passengers placed between a step for carrying one passenger and a skirt guard adjacent thereto. This invention relates to a structure suitable for preventing personal accidents.

[Conventional technology]

In general, the steps of a passenger conveyor are configured to move in an endlessly connected state from one entrance/exit to the other. The step has a cleat and a riser that forms a riser on the rear surface of the step and has a number of vertical peaks. Further, there are skirt guards arranged on both sides of the cleat and riser so as to face them with a slight gap between them.

The structure described here will be briefly explained with reference to FIGS. 4 and 5. The cleat 10A of step 10 is provided with many irregularities so as to engage with the tips of the teeth of the comb provided at the entrance.
Transported on board 0B. Further, the surface of the riser 10C that closes the rear surface of the step 10 is provided with a large number of unevenness so that the front end 10AA of the cleat IOA is engaged with in the vertical direction, and this also has a large number of top portions 10D. Furthermore, cleats 10A forming both sides of this step 10
Near the side 10a of the riser 10c and the side 10b of the riser 10c,
A flat plate-shaped skirt guard 20 is fixed to the parapet with a gap g of only about 2 to 31 mm.

In this manner, it is described in Japanese Utility Model Publication No. 13918/1983 that the tips of the passengers' shoes are drawn into the gap g between the moving step 10 and the fixed skirt guard 20. This personal trouble occurs when the step 10 is moving in the upward direction, from arrow A (Fig. 4) to arrow Aa, and when the step 10 is moving in the downward direction, it is shown by arrow B (Fig. 5). As shown by arrow Bb, cleat IOA, riser 10C and skirt guard 2
In this known example, the area near the skirt guard 2o in step 10 is colored in a yellowish caution color to call attention to it. - Ho, Jitsuko 4'0-6
In Publication No. 033, as illustrated in FIG.
An attempt is being made to provide an elastic rubber piece Sa on the side of the shoe and bend it as shown in the imaginary line to close the gap g when the toe of a shoe approaches and an external force as shown by arrow C is generated.

In addition to this known example, there are also known structures in which only the side part of the step 10 is made taller, as shown by the imaginary line Y in FIG. ing.

[Problem to be solved by the invention]

Among the above-mentioned known examples, the former yellow-colored one has a visual alerting effect, but the moment the tip of a shoe approaches the entrance of the gap g as shown by arrows A and B, the narrow gap At this time, the step 10 and the skirt guard 20 are deformed, and furthermore,
No improvements have been made to the phenomenon of being drawn into the depths.

In addition, in the case of the latter rubber piece Sa, when weight is applied directly above it, it easily sinks in the vertical direction;
It is estimated that the danger increases at the part where it engages with the coat.

The present invention aims to prevent personal accidents occurring between the step and the skirt guard.

[Means to solve the problem]

In order to achieve the above object, in the step of the present invention, the entrance portion of the gap between the cleat and the riser, or the skirt guard, is positioned at both ends of the cleat and the riser, or at least one of them, so that the entrance portion of the gap between the cleat and the riser is lower than the gap. The step also has a sloped surface that opens wide, and has side teeth fixed in a different color from the step.

[Effect]

The side tooth pieces are shaped to protrude toward the skirt guard in the direction of reducing the gap, which reduces dangerous gaps and also creates a space on the slope where the toe of a shoe that tries to enter the gap can stay. Form. This reduction in the gap is particularly suitable for improving the safety of older products whose gaps have widened over time.

Furthermore, while the tip of the shoe remains on the slope, it will not be pulled in, and even if it should become caught, it can be easily pulled out along the slope, further improving safety.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1, 2, and 3, using a cleat on the upper surface of a step as a representative example.

In the figure, the skirt guards 2 of the parapet are arranged on both sides of the step 1 of the present invention as in the conventional case, but on both sides of the cleat IA of this step 1 itself, side tooth pieces IB
It is equipped with Here, the side tooth piece IB is the outer surface 1aa of the cleat 1a at the side end.

It has a shape that covers the top part 1bb and the inner surface 1cc, and is fixed with adhesive IC or screws at the cleat groove part 1dd, and furthermore, the wide gap between this step 1 and the skirt guard 2 The direction in which G is reduced, that is,
It has a shape that protrudes toward the skirt guard 2 side, forming a regular small gap g, and has a slope part iff provided at the top Lee to open the entrance part of the gap g, and has a yellowish color different from Step 1. is colored. Moreover, this slope part iff is provided at a part that is higher than the top part 1bb of the cleat 1A by h, and the opening width of the inlet part is the third height.
As indicated by the symbol W in the figure, it is formed wider than the gap g. The shoe tip X that approaches this slope part if moves while remaining in the retention space M at the entrance, but if a retraction force arrow P is generated on the shoe tip X, the passenger notices something wrong with the tip of the foot and pulls out the shoe in the direction along the slope as shown by arrow Q.As a result, the passenger is alerted by the color tone, has enough time to pull in due to retention, and pulls out the shoe diagonally along the slope part if. It can be easily pulled out. In addition, it is protected by the safety effect of reducing dangerous gaps in older escalators.

Note that it goes without saying that the side teeth can be applied to the riser ID as is, and the best material is synthetic resin, which is easy to mold and color. Also, this side tooth piece can be used as both a cleat and a riser.

It may be provided on either one.

〔Effect of the invention〕

According to the present invention, safety between the step and the skirt guard is improved.
