Abstract

PROBLEM TO BE SOLVED: To make a danger sensible, and prevent an accident such as the toe of a shoe is pulled in between a tread of a lower stage and a riser of an upper stage by providing a demarcation plate which projects upward from a footstep at ordinary time and sinks by force from above, in an attention belt part of a front end part. SOLUTION: A demarcation plate 4 whose upper end part has the same height as the upper end of a demarcation cleat is arranged in a front end part of a cleat 2 to form a tread of a footstep 1. This is a circular hollow body whose cross section is almost 1/4, and a recessed part 4B is arranged in its plane bottom part 4A, and a hole 4C is arranged in this. On the other hand, an installing part 5 of the demarcation plate 4 is arranged in a front end part of the footstep 1, and the demarcation plate 4 is screw-fitted to and installed in a screw part 5A through a coil spring 9. Therefore, even if a user moves his feet forward at rising time, a sense of incompatibility is imparted by reaction of the coil spring 9, and a danger is informed, and contact of the toe of a shoe to a riser 10 of the tread 1 of an upper stage is prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator step, and more particularly to an escalator step suitable for ensuring the safety of escalator users.

[0002]

2. Description of the Related Art A step which has moved while forming a step at an intermediate slope of an escalator becomes smaller as it gets closer to the exit, and adjacent steps become horizontal to each other near the exit.

[0003] Here, when the shoe tips are pressed against each other at an acute angle formed by a cleat, which is the tread of the lower step, and a riser, which is the rising portion of the upper step, while the intermediate slope is advancing, When the step approached the step-reducing part, there was a risk that the shoe tip could get between the lower cleat and the upper riser, causing injury.
No. 575, in a step of an escalator having a caution belt at least on both side end portions and a front end portion of a step cleat,
There has been proposed an escalator step formed by inclining the caution belt at the front end portion to a higher height.

[0004]

SUMMARY OF THE INVENTION In the prior art described above, the warning belt portion, which is provided with the yellow paint and is provided on the front end portion of the tread surface of the step of the escalator, is provided at the entrance / exit because it is raised. The gap between the comb plate and the lower end of the comb plate attached to this comb plate and the tread of the step is wider behind the tread at the front end of the tread, so that pebbles can be easily caught between the comb plate and the tread. As a result, the comb plate is often broken and the steps are damaged, and if the comb plate is broken, there is a risk of an accident in which the foot of the escalator user gets into the gap between the comb plate and the tread surface. .

An object of the present invention is to provide a step of an escalator which prevents an accident in which a user's foot is caught in a step-reducing portion of a step and an entrance / exit portion.

[0006]

In order to achieve the above object, the present invention provides a step of an escalator in which the tread surface of the step is formed with at least both side end portions and a caution band of the front end at a tip height. The caution band is provided with a demarcation plate that normally projects upward from the step and is retracted by a force from above.

Further, according to the present invention, since the user of the escalator moves the foot to the front end of the tread surface, the projecting demarcation plate causes the tip of the foot to come into contact with the riser of the upper step. Not only that, but it also gives a sense of incongruity even if you put your foot on the demarcation plate and push down the demarcation plate, so that you can prevent accidents where the shoe tip is pulled between the lower step and the upper riser. In addition, it is not necessary to widen the gap between the tread surface and the lower end of the comb plate to which the comb plate is attached by being pushed down by the protruding demarcation plate at the lower end of the comb plate at the exit, so the user at the exit can You can secure the safety of your toes.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view of a step of an escalator according to one embodiment of the present invention, and FIG. 2 is a sectional view taken along the line AA of FIG. 1 at an escalator entrance / exit of one embodiment of the present invention.

In the figure, a detachable demarcation cleat 3 is provided at both ends of a cleat 2 which forms the tread surface of the step 1, and which has a height higher than the upper end of the cleat 2.
A demarcation plate 4 is provided at the front end of the cleat 2 so that the upper end thereof has the same height as the upper end of the demarcation cleat.

The demarcation plate 4 is a hollow body having a substantially quarter circular cross section, and is made of the same plastic as that of the demarcation plate 3, and the demarcation plate 4 has a flat bottom 4A. Recess 4B
And a hole 4C provided in the recess 4B is provided.

A mounting portion 5 for the demarcation plate 4 is provided at the front end of the step 1, and the mounting portion 5
Must be located below the upper end of the cleat 2 by a dimension longer than the dimension of the demarcation plate 4 moving downward. Here, the moving dimension of the demarcation plate 4 is a dimension obtained by adding the dimension of the upper end of the cleat 2 and the dimension of the upper end of the demarcation cleat 3 and the dimension of the upper end of the cleat 2 and the lower end of the comb plate 6. Further, the comb plate 6 is attached to a comb plate 7 of a not-shown entrance / exit of the escalator.

The demarcation plate 4 is mounted on the mounting portion 5 by mounting the bolt 8 from the inside into the hole 4C of the recess 4B of the demarcation plate 4 and inserting the bolt 8 into the coil spring 9. It is screwed onto the screw portion 5A.

In this way, the step 1 of the escalator provided with the demarcation plate 4 which can be freely projected can prevent the demarcation plate 4 from moving even when the user moves his / her foot forward during the ascending.
Since the shoe tip comes into contact with the rising portion 4D, the shoe tip does not come into contact with the riser 10 of the upper step 1. In addition, even if the passenger steps on the demarcation plate 4, the reaction force of the coil spring 9 gives an uncomfortable feeling to notify the danger.

The demarcation plate 4 is pressed by the lower end of the comb plate 6 and moves downward.

As described above, by providing the demarcation plate 4 which can be retracted and retracted at the front end portion of the step 1, it is possible to reduce the number of accidents in which the shoe tip of the escalator user is caught.

In the present embodiment, the demarcation plate 4 having a substantially quarter circular cross section has been described, but the demarcation plate 11 having a substantially semicircular cross section has the same effect, and a plurality of demarcation plates are provided. Even if the demarcation plate 4 is attached to the attachment portion 5, the same effect can be obtained.

[0018]

According to the present invention, even when the user of the escalator moves his or her foot to the front end of the tread, the protruding demarcation plate prevents the foot tip from contacting the riser of the upper step, and the hoax Even if you step on the application plate with your foot, it gives a sense of discomfort and makes you sense the danger, so you can prevent accidents where your toes are pulled in between the lower tread and the upper riser. In addition, the protruding demarcation plate is pushed down by the lower stage of the comb plate at the entrance, and it is not necessary to widen the gap between the lower end of the comb plate and the lower end of the comb plate to which the comb plate is attached and the tread surface. You can secure the safety of your toes.
