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

Example Embodiment

[0048] (Example 1)

[0049] Active Figure 1 to Figure 9 The structure of Embodiment 1 will be described.

[0050] figure 1 It is a side view of step 1 of an escalator. The upper part of the step 1 has a tread 2 on which passengers ride up or down. In the following description, figure 1 The direction of travel when step 1 ascends ( figure 1 The center is the right side) is defined as the front side and the opposite direction ( figure 1 The middle is the left side) is defined as the back side for illustration. A step riser 3 is provided at the rear end of the step 1, and a corner portion (part A in the figure) is formed at the upper portion of the stepped riser 3 intersecting the rear end of the tread 2.

[0051] figure 2 with image 3 It means that the corners are seen along the step baffle 4 from near the center of step 1 ( figure 1 A partial perspective view of the state. figure 2 It shows the state after the impact absorbing splint 5 is installed on the main body 6 of the trea...

[0074] (Example 2)

[0075] Active Figure 10 to Figure 12 To illustrate Example 2.

[0076] The difference between Example 2 and Example 1 is that the materials of each part constituting the impact-absorbing splint 20 are different, and their outer shapes are the same. Therefore, different parts will be described below, and descriptions of other parts will be omitted.

[0077] The impact-absorbing splint 20 of Example 2 also uses two types of urethane rubbers, urethane rubber with relatively high hardness and urethane rubber with relatively low hardness.

[0078] Picture 10 Is the cross section of the base 23 showing the short peak 21 and its lower part ( Figure 5 Section A-A in). The short peak 21 and the base 23 use relatively hard materials.

[0089] (Example 3)

[0090] Active Figure 13 to Figure 15 To illustrate Example 3.

[0091] The difference between Example 3 and Example 1 is that, similar to Example 2, the materials of each part constituting the impact-absorbing splint 30 are different, and their outer shapes are completely the same. Therefore, different parts will be described below, and descriptions of other parts will be omitted.

[0092] The impact-absorbing splint 30 of Example 3 also uses two types of urethane rubbers, urethane rubber with relatively high hardness and urethane rubber with relatively low hardness.

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...
