Step of automatic escalator

Abstract

The invention provides a step of an automatic escalator, wherein a corner part of a crossed part between a tread surface and a tread vertical plate part is provided with a clamping plate used for absorbing impact. The tread surface main body adopts the aluminum or the stainless steel and other metal materials. The clamping plate adopts the elastomer containing the natural rubber, the synthetic rubber, the polyurethane rubber, the silicone rubber, and the fluororubber. According to the step, the clamping plate adopts more than two elastomers. By adopting the invention, the safe automatic escalator can be provided, and without using the high-price device, the head of the passenger can be protected from being injured severely, even when the head is collided with the corner of the step. And in addition, the passenger cannot easy fall down even during the common utilization state.

Description

technical field [0001] The invention relates to a step of an automatic elevator. Background technique [0002] Overturning accidents often occur in automatic elevators, especially when the body collides with the corner where the tread of the step and the riser face intersect (hereinafter referred to as "the corner of the step"), there is a possibility of serious injury. Therefore, there is a need for a safe automatic elevator that can absorb the collision energy even if the head hits the corners of the steps when it falls down, so as to prevent serious injuries. However, it is not a structure that encourages the passenger to fall in a normal use state even if the injury is prevented from becoming serious when the vehicle falls over. [0003] Conventionally, several methods have been proposed as measures to prevent serious injuries when the body collides with the step corner. For example, Japanese Patent Laying-Open No. 2008-254873 (Patent Document 1) proposes such an autom...

AI Technical Summary

Problems solved by technology

These mechanisms are required for each step, so there is a problem that the cost of the escalator as a whole is very high

In addition, when the mechanism does not work, it is very likely to cause damage to the comb teeth of the entrance and exit part, thereby damaging all the steps

In addition, the comb teeth are subjected to force and rubbed every time they pass through the steps, so there are concerns about fatigue damage and wear

As such, there are problems of high cost and low reliability in this method

[0007] In addition, in the method proposed in Patent Document 2, since the comb plate is made of rubber or synthetic resin, there is a problem that it is easier to wear than the conventional comb plate, and it is easy to adhere to dirt and dirt, and its life is short.

In addition, when replacing the comb plate that has reached the end of its life, there is a problem that the entire tread must be replaced, and the replacement takes a lot of time and money.

In addition, when the comb plate is made of rubber, if the weight of the passenger acts on the comb plate to deform, the pedals will become unstable, which may cause the passenger to fall.

[0008] In addition, the method proposed in Patent Document 3 has the problem of not taking countermeasures for the corners of the most dangerous steps from the viewpoint of preventing serious injuries, since the original purpose of the proposal is to prevent vibration transmission.

The elastic vibration suppression material placed between the steps and the frame is not sufficient to absorb the impact energy, so there is also a problem that it is ineffective in preventing serious injuries

In addition, since the elastic damping material is laid on most of the base of the tread, there is a problem of increased material costs, assembly costs, and high costs.
