Abstract

PROBLEM TO BE SOLVED: To prevent the adhesion of foreign matter on a side face part in a sill groove and remove the foreign matter adhered easily by providing a foot main body of a door which is provided in a lower end part of the door of an elevator and is inserted in the sill groove and a side face part cleaning member which is provided in the foot main body of the door and removes foreign matter adhered on the side face part by coming into slide-contact with the side face part in the sill groove. SOLUTION: A foot main body 11 of a door is fixed in a lower end part of the door 1 by using a mounting bolt 4. The foot main body 11 of the door is inserted into a sill groove 2a to guide the opening and closing of the door 1. A brush 12 as a side face part cleaning member is provided in both end face parts in the longitudinal direction of both side face parts of the foot main body of the door to come into slide-contact with both side face parts in the sill groove 2a when the door 1 is opened and closed. The brush 12 is a nylon brush, a bundle of hairs is inserted to pass through a foot 11 of the door, and its length is such extent that a tip comes into contact with the side face part of the sill groove 2a when the door 1 is stationary. Since the brush 12 moves in slide-contact with a side face in the sill groove 2a when the door 1 is opened and closed, it is possible to remove viscous foreign matter adhered on the side face part of the sill groove 2a automatically.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot of an elevator door which is provided at a lower end portion of a landing door or a door of a car and is inserted into a sill groove to guide opening and closing of the door.

[0002]

2. Description of the Related Art FIG. 4 is a front view showing a lower end portion of a conventional elevator door disclosed in, for example, Japanese Utility Model Laid-Open No. 54-20463, FIG. 5 is an enlarged view of a main portion of FIG. 4, and FIG. FIG. In the figure, 1 is a door of a hall or a car, 2 is a sill fixed to the hall or a car, and this sill 2 is provided with a sill groove 2a along the opening and closing direction of the door 1. 3 is fixed to the lower end of the door 1 by a mounting bolt 4,
It is a foot of the door inserted in the threshold groove 2a.

Reference numeral 5 is a brush mounting base fixed to the door 1 by brush mounting bolts 6, and 7 is a brush implanted in the brush mounting base 5. The brush 7 is inserted into the sill groove 2a. There is.

If foreign matter falls into the sill groove 2a, it may hinder the movement of the foot 3 of the door when the door 1 is opened and closed. Therefore, a brush 7 is attached to the door 1 as a foreign matter removing tool. The foreign matter in the sill groove 2a is moved along the sill groove 2a by the brush 7 when the door 1 is opened and closed, and is dropped into the hoistway from a hole (not shown) provided in a part of the bottom of the sill groove 2a. .

[0005]

In the conventional elevator constructed as described above, the normal foreign matter entering the sill groove 2a falls to the bottom of the sill groove 2a and is therefore removed by the brush 7. If a foreign substance having high adhesiveness, such as juice or wax, adheres to the side surface of the sill groove 2a, the brush 7 cannot remove the foreign matter and hinders the movement of the foot 3 of the door. was there. Therefore, it is necessary for the worker to regularly inspect and clean the inside of the threshold groove 2a.

The present invention has been made to solve the above-mentioned problems, and prevents foreign matter from adhering to the side surface in the sill groove and facilitates the prevention of foreign matter. Aims to get elevator door legs that can be removed to.

[0007]

A foot of an elevator door according to the invention of claim 1 is provided at a lower end portion of the door of the elevator and is inserted into a sill groove, and a foot body of the door. A side surface cleaning member that is provided on the main body and is in sliding contact with the side surface in the threshold groove to remove foreign matter attached to the side surface is provided.

The foot of the door of the elevator according to the second aspect of the present invention uses a brush fixed to the foot body of the door as a side surface cleaning member.

In the foot of the elevator door according to the third aspect of the present invention, a brush, which is a side surface cleaning member, is inserted and attached to a hole provided at a longitudinal end portion of the foot body of the door. There is something.

The foot of the door of the elevator according to the invention of claim 4 uses a felt material fixed to the foot body of the door as a side surface cleaning member.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view showing a lower end portion of an elevator door according to an embodiment of the present invention, FIG. 2 is an enlarged view of an essential part of FIG. 1, FIG. 3 is a side view of FIG. 2, and FIGS. The same or corresponding parts are designated by the same reference numerals, and the description thereof will be omitted.

In the figure, numeral 11 is a foot body of the door fixed to the lower end portion of the door 1 by a mounting bolt 4, and the foot body 11 of the door is inserted into a sill groove 2a to open and close the door 1. invite. Reference numeral 12 is a brush as a side surface cleaning member provided at both ends in the longitudinal direction of both side surface portions of the foot body 11 of the door. These brushes 12 slide on both side surface portions in the sill groove 2a when the door 1 is opened and closed. I have come into contact with them.

Further, as shown in FIG. 3, the brush 12 is
A bundle of hairs is inserted and fixed in a hole 11a that penetrates the foot body 11 of the door. Furthermore, the brush 12 is made of, for example, a nylon brush, and its length is preferably such that the tip of the brush 12 is in contact with the side surface of the threshold groove 2a when the door 1 is stationary.

In such an elevator, when the door 1 is opened and closed, the brush 12 is adapted to move in sliding contact with the side surface portion in the sill groove 2a, so that the wax or the like attached to the side surface portion in the sill groove 2a is moved. Foreign substances with high adhesiveness can be automatically removed. Further, when juice or the like adheres to the side surface portion of the threshold groove 2a, it can be removed by the brush 12 before it dries and becomes more sticky, so that sticky foreign matter can be prevented from sticking. Therefore, it is possible to omit periodical inspection and cleaning of the side surface of the threshold groove 2a.

Further, in the above example, the holes 12a are provided at both ends of the door body 11 in the longitudinal direction to allow the brushes 12 to pass therethrough. However, both ends of the body 11 of the door in the longitudinal direction are core materials. Since the metal plate 11b is not included, the hole 11a can be easily processed, and since the brush 12 is long, it is easy to handle.

Further, the longitudinal ends of the door body 11 are usually provided with tapers in the thickness direction, and the thickness of the longitudinal ends is slightly smaller than the thickness of the intermediate part. Therefore, by disposing the brushes 12 at both ends in the longitudinal direction, the amount of protrusion of the brush 12 from the foot body 11 of the door can be increased, and the brush 12 can be provided with appropriate flexibility. Thereby, the abrasion of the brush 12 can be suppressed.

In the above example, the side surface brush 12 is used.
However, it goes without saying that it may be used in combination with the brush 7 for cleaning the bottom surface portion of the threshold groove 2a as shown in FIG.

Further, although the brush 12 is shown as the side surface cleaning member in the above-mentioned example, the present invention is not limited to this, and, for example, a felt material is attached to the side surface of the foot main body 11 of the door to form the sill groove 2a. You may make it wipe off the dirt of a side surface part.

Further, the size and number of the side surface cleaning members can be changed as required.
