Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator step protector for protecting an escalator step.

[0002]

2. Description of the Related Art Generally, a step of an escalator is formed with a tread surface on which an occupant rides, and a riser surface which is curved on the side adjacent to this tread surface and joined to the tread surface of another step. ing.

Conventionally, when the steps of the escalator are used as a transportation path for transporting the equipment at the time of installing the escalator or repairing the premises equipment for installing the escalator, in order to protect the tread surface and the riser surface from stains. Protective equipment was installed.

An example of such a protector is Japanese Patent Laid-Open No. 2-1.
As disclosed in Japanese Laid-Open Patent Publication No. 47596, a plate member 2 that removably engages with a tread surface 1 to protect the tread surface as shown in FIGS. The cleat groove 1a of the tread 1 is composed of a sheet member 4 which is engaged with the riser surface 3 and protects the riser surface 3 and which is provided on the plate member 2.
The protective device was configured to hold the step covered by engaging with the step.

Numerals 5 and 6 are guide rollers for guiding the step up and down, the former being an upper guide roller and the latter being a lower guide roller. The upper guide roller 5 is connected to the step via a shaft 7.

[0006]

However, in the above-mentioned prior art, since the plate material is required to protect the tread, the material cost of this plate material, and the processing cost for attaching the projection provided on the plate material to the plate material, In addition, processing costs such as attaching the sheet member that protects the riser surface and the plate member are required, so the cost is significantly increased compared to the belt-shaped sheet member-only protector that was used before this conventional technology. There was a problem that it would end up.

Further, since such a protector is used temporarily during the installation or repair work of the escalator as described above, it is necessary that the protector be easily transported. If used, the volume and weight of the product will increase, which makes it difficult to carry the product, and there is also a problem that the space must be wide for storage.

The present invention has been made in view of the above problems, and an object thereof is to reliably protect the steps of the escalator and at the same time, at a low cost, and to easily carry the step protector of the escalator. To provide.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a tread formed by each step which is endlessly connected and guided by a roller which is connected at its lower part via a shaft. In the step protector of the escalator that covers the riser surface adjacent to the tread surface and protects the step, a strip-shaped body installed so as to cover the tread surface and the riser surface of the step, and one end thereof is fixed to the strip-shaped body. In addition, it has a stopper member that engages with the shaft at the other end.

[0010]

As described above, according to the present invention, the step protector of the escalator is configured so that the belt-like body installed so as to cover the tread surface and the riser surface of the step is fixed to the shaft connected to the lower portion of the step by the stop member. With a simple structure, the state in which the strip covers the step can be maintained, and thus the step can be protected reliably.

[0011]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a method of attaching a step protector for an escalator according to the present invention, and FIG. 2 is a side sectional view showing an embodiment of a method for attaching a step protector for an escalator according to the present invention. FIG. 3 is a perspective view showing the configuration of an embodiment of a stopper member provided in the step protector of the escalator of the present invention.

In the figure, the same reference numerals as those used in the description of the prior art described above indicate the same elements.

First, the structure of the protector of this embodiment will be described.

In the figure, reference numeral 8 is a belt-like member installed so as to cover the surfaces of the tread surface 1 and the riser surface 3 of the step,
The stopper member 9 fixes and holds the upper guide roller 5 on the upper guide roller shaft 7 that connects the upper guide roller 5 to the step.
The material of the strip 8 is preferably a cloth-like material having elasticity such as a vinyl sheet.

As shown in FIG. 2, the stopper member 9 has a mounting member 9a sewn on the back surface of the belt-shaped body 8 and a rubber or metal spring which is mounted and fixed to the belt-shaped body 8 by the mounting member 9a. The elastic body 9b is composed of an elastic body 9b and a mounting member 9c which is coupled to the elastic body 9b and engages with the upper guide roller shaft 7.

Next, a method of attaching the protector of this embodiment will be described.

First, as shown in FIG. 1, the strip 8 is installed so as to cover the entire steps. As shown in FIG. 2, the band-shaped body 8 is formed so as to cover a part of the skirt guard 10 installed on the side portion of the step. It prevents foreign matter from entering.

On the back surface of the strip-shaped body 8, the elastic body 9 is formed.
mounting bracket 9 mounted via b and mounting member 9a
c is inserted from the gap between the skirt guard 10 and the step, and the U-shaped tip portion is engaged with the upper guide roller shaft 7.

As described above, according to this embodiment, since the belt-shaped body 8 is fixedly held on the step by the stopper member 9,
The step surface can be surely protected by the strip 8 without the strip 8 being displaced from the step. In addition,
Since the mounting member 9 is provided in a simple structure, its volume and weight can be kept small, and it can be easily transported.

Further, since the stopper member 9 is provided on the back surface of the belt-shaped body 8, it is not affected even if the belt-shaped body 8 is stepped on the front surface thereof. Therefore, the stopper member 9 is once engaged with the upper guide roller shaft 7. Then it can be prevented from coming off.

Further, the stopper member 9 is attached to the mounting fitting 9
Since c is attached to the strip 8 by the attaching member 9a via the elastic body 9b, tension is applied to the attachment metal 9c when the attachment metal 9c is engaged with the upper guide roller shaft 7, and the engagement is made firm. Can be one.

Next, another embodiment of the method of attaching the protector of the present invention will be described.

FIG. 4 is a perspective view showing a method of mounting a protector according to another embodiment of the present invention, and FIG. 5 is a side sectional view showing a method of mounting a protector according to another embodiment of the present invention.

In the present embodiment, as a method of attaching the strip 8 to the step, the strip 8 is attached to the step by engaging a stopper member 9 on the back surface of the tread 1 of the step.

That is, as shown in FIG. 5, one end of the mounting member 9c having the elastic body 9b and the mounting member 9c attached to the strip 8 is inserted through the gap between the skirt guard 10 and the step, and the tread of the step is inserted. The belt-like body 8 is attached and fixed to the step by engaging with the back surface of the belt 1.

As described above, according to the present embodiment, since the stopper member 9 is engaged with the rear surface of the tread surface 1, it is possible to easily attach the belt-shaped body 8 to the step.

[0028]

As described above, the present invention has the following features.
Since the protector can be always held so as to cover the step with a simple structure, the step can be reliably protected, and the step protector of the escalator can be inexpensive and easy to carry.
