DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sill groove cleaning device for an elevator, and more particularly to completely cleaning a sill groove.

[0002]

2. Description of the Related Art Conventionally, this type of elevator sill groove cleaning device has been used, for example, in Japanese Utility Model Laid-Open No. 3-95.
No. 369, and the configuration shown in FIGS. 6 and 7 is adopted. That is, in FIG. 7, reference numeral 1 denotes a sill having a sill groove 2, and a door 4 is slidably provided along the arrow A in the sill groove 2 via a protrusion 3.

As shown in FIG. 6, a connecting member 6 having a brush 5 integrally fixed is provided between a guide piece 4A provided on the door 4 and the projecting portion 3. The pair of protrusions 6a and 6b formed on the coupling member 6 are fixed to the guide piece 4A by bending. Therefore, in the above-described configuration, when the door 4 is opened and closed along the arrow A, the brush 5 also moves at the same time, and dust and the like in the threshold groove 2 can be removed.

[0004]

Since the conventional elevator sill groove cleaning device is configured as described above, the following problems exist. That is, when foreign matter such as pebbles is contained in the sill, cleaning is performed only by the elastic force of the brush. Therefore, when there is foreign matter such as pebbles exceeding the elasticity of the brush, the elastic force of the brush is However, foreign objects could not be pushed out in the direction of movement of the door, and pebbles were caught between the protrusion of the door and the sill groove, which hindered the opening and closing of the door.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an elevator sill groove cleaning device for completely cleaning the inside of a sill groove.

[0006]

Means for Solving the Problems Claim 1 according to the present invention
An elevator sill groove cleaning device for an elevator, wherein the sill groove cleaning device is configured to clean the sill groove with a brush of a mounting piece of a mounting plate provided at a lower portion of the door, wherein the mounting piece is adjacent to the brush. This is a configuration in which pins are provided.

According to a second aspect of the present invention, there is provided an elevator sill groove cleaning device for cleaning a sill groove with a brush of a mounting piece of a mounting plate provided at a lower portion of a door. And a cleaning piece provided at an end of the mounting plate, wherein the cleaning piece is located near the brush.

[0008]

In the elevator sill groove cleaning apparatus according to the first aspect of the present invention, when the door is moved, pebbles and the like that cannot be removed only by the elastic force of the brush can be removed by the elastic force of the pin. Thorough cleaning and smooth movement of the door can be obtained.

In the elevator sill groove cleaning device according to the second aspect of the present invention, when the door is moved, the cleaning piece located on the upstream side of the brush collides with the pebble before the brush, and the pebble is broken or moved. Then, it is completely removed by the elastic force of the brush.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an elevator sill groove cleaning device according to the present invention will be described below in detail with reference to the drawings. Note that the same or equivalent parts as those in the conventional example will be described using the same reference numerals.

Embodiment 1 FIG. 1 and FIG.
Reference numeral 0 denotes a mounting plate mounted on the lower part of the door 4 of FIG. 5 through mounting holes 10a and screws (not shown). Is a pin made of a hard material such as iron, which is provided adjacent to the brush 5 of the mounting piece 11 and has a larger elastic force than the brush 5. This pin 12
Is connected to the end portion 10b through the mounting piece 11, and the mounting piece 11, the brush 5 and the pin 12 are formed integrally with the mounting plate 10 by heating using the mounting piece 11 as a resin. Is formed. It should be noted that, besides integral molding, it can be made separately and bonded.

Therefore, when the cleaning device 20 having the structure shown in FIGS. 1 and 2 is attached to the lower portion of the door 4 of FIG. 5 via the guide piece 4A and the door 4 is moved, the cleaning is performed only by the elastic force of the brush 5. Unavailable pebbles and the like can be removed by the elastic force of the pin 12, and the inside of the threshold groove 2 can be completely cleaned.

Embodiment 2 FIG. In FIGS. 3 and 4, the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals, and the description thereof will be omitted. Only different parts will be described. A cleaning piece 30 (having a greater elastic force than the brush 5) made of an iron piece or the like extending in the same direction and parallel to the brush 5 is integrally formed at an end 10b of the mounting plate 10, and this end is formed. Part 1
A mounting piece 11 is provided at 0b.

The cleaning piece 30 is located on the upstream side of the brush 5, and the mounting piece 11 and the brush 5 are used in the first embodiment.
In the same manner as described above, it is formed by integral molding or adhesion by heating. Accordingly, the cleaning device 20 shown in FIGS.
5 is attached to the lower part of the door 4 in FIG. 5 (not shown), and the door 4 is moved. Then, the foreign matter is removed by the elastic force of the brush 5. The mounting piece 11 in FIGS. 1 to 4 described above.
The mounting configuration of the pin 12 is not limited to molding by heating, and any means such as fitting and welding can be used.

[0015]

In the first embodiment of the elevator sill groove cleaning device according to the present invention, since the brush and the pin are combined, pebbles and the like that cannot be removed by the elastic force of the brush alone are removed through the elastic force of the pin. As a result, foreign matter staying in the sill groove can be completely removed, and a failure due to poor opening and closing of the door can be prevented. Further, in the second embodiment, since the combination of the brush and the cleaning piece, when the door is moved,
The cleaning pieces destroy or move the pebbles and the like in the sill groove to weaken the force, so that the cleaning can be easily performed even with the elastic force of the brush, and the door can be smoothly opened and closed at all times.
