Description

[Detailed Description of the Invention] The present invention relates to an elevator door guide cleaning device.

Generally, elevator doors are provided on each floor 1 of a building and on an elevator car 2, as shown in FIG. In these doors, a door hanger 4 is provided on the upper part of the door body 3, and a hanger roller 5 is attached to this. On the other hand, on the floor 1 or elevator car 2 side, a rail mounting plate 6 is provided on the upper frame, and a guide rail 7 is attached to this rail mounting plate 6. The hanger roller 5 of the door is placed on this guide rail 7, and the door body 3 is moved (opened and closed).

By the way, the rail mounting plate 6 has a conventional shape,
Door running devices such as the hanger rollers 5 and the guide rail 7 are covered to prevent dust, mortar dust, etc. generated as the elevator goes up and down from adhering to the guide rail 7 to some extent. However, this level was insufficient.

On the other hand, recently, in order to reduce weight and cost, flat-shaped rail mounting plates 6 have been widely used instead of round-shaped rail mounting plates 6, which has made it easier for dust to adhere to the guide rails 7. Therefore, due to this deposit,
The door may not open and close smoothly, and in some cases, the door may not open, resulting in what is known as a canned food accident. As described above, adhesion of dust to the guide rail 7 can lead to serious accidents. As buildings have become taller in recent years, the number of floors where elevators stop has increased, and the number of locations where the guide rails 7 must be installed has become enormous. From a physical perspective, considering the amount of effort involved, it would have been economically impossible.

The present invention was made to solve these problems, and an object of the present invention is to provide an elevator door guide cleaning device that always keeps the door guide rail clean and allows the guide roller to roll smoothly. It is an object.

The following is an example of the present invention shown in Figures 2 to 4.
This will be explained with reference to the figures. 12 is a cleaning tool, and a thin steel plate or a plastic plate is used. This cleaning tool 12 consists of a chuck part 9 whose open end 8 is bent into a narrow U-shaped cross section, and which allows the object to be caught by the elasticity of the plate.
Brush holder 1 installed in a right angle direction above the
0 and a brush 11 inserted into the U-shape of this brush holder 10.

This cleaning tool 12 is inserted and attached to the door hanger 4 by the chuck portion 9 as shown in FIG. At this time, the brush 11 is pressed against the guide rail 7.

Next, the operation of the above embodiment will be explained. Since the brush 11 slides on the guide rail 7 every time the door opens and closes, the dust and the like on the guide rail 7 is constantly swept away. Also, when the brush 11 wears out, the chuck portion 9 is only held by the elasticity of the plate.
All you have to do is press the cleaning tool 12 downward. Alternatively, when the brush 11 becomes worn, the cleaning tool 12 can be removed from the door hanger 4 and the brush 11 can be replaced very easily.

Further, by providing unevenness on the inside of the chuck portion 9 of the cleaning tool 12 or by attaching a rubber plate, it is possible to ensure that the chuck portion 9 is bitten. Also, if the root of the brush holder 10 is made to have elasticity by changing the orientation of the mounting plate so that the brushes 11 are always pressed against the guide rail 7 with elasticity, the brushes 11 will follow the wear of the brushes. This is convenient because it moves.

As explained above, according to the present invention, the guide rail of the door is always kept clean and the guide roller rolls smoothly, so the function of the door is not impaired and serious accidents such as canning accidents are prevented. It also becomes.
In addition, it also has the effect of saving labor in terms of maintenance management.
