[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator door having a function of removing dust existing around a sill, and further to a sill structure suitable for the elevator door.

[0002]

2. Description of the Related Art Elevator doors having a sill cleaning brush attached to a door shoe are used at a site where much dust is present. If this door is used, dust that has entered the sill can be cleaned with a brush, and the elevator door can be opened and closed smoothly.

18 and 19 show the structure of an elevator door according to a conventional example. In the figure, reference numeral 1 indicates a car door, and reference numeral 7 indicates a hall door. The car door 1 is suspended on a door rail 18 of a car room 17 by a hanger roller 19 provided at the upper end of the car door 1. Legs 3 are provided at the lower end of the car door 1. Leg 3
When the car door 1 opens and closes, it is guided by the car sill 4. The landing door 7 is also suspended by the same structure, and the leg portion 6 provided at the lower portion thereof is guided by the landing sill 5.

A sill brush 24 or 24a is provided on each of the legs 3 and 6 of the car door 1 and the landing door 7, respectively. The sill brushes 24 and 24a are the cage sill 4 as shown in the enlarged view of the sill brush 24 in FIG.
Alternatively, it has a function of removing the dust 8 that has fallen inside the hall threshold 5. That is, the threshold brushes 24 and 24a
Are provided at the front and rear of the corresponding leg 3 or 6, that is, at the left end and the right end in FIG. 19, and dust existing in the moving direction X of the car door 1 or the landing door 7 affects the guidance of the leg 3 or 6. The dust 8 is removed so that the dust is not given. This allows
The car door 1 and the landing door 7 can be smoothly opened and closed.

[0005]

However, in such a structure in which the brush is provided inside the sill, it is not possible to completely remove the dust existing in the sill, and the dust left unremoved remains at the edge of the sill. Collect in the section. This impairs the aesthetic appearance of the sill of the elevator door and, in a remarkable case, hinders the opening / closing operation of the elevator door.

The present invention has been made to solve these problems, and by improving the means for cleaning the sill, it is possible to prevent dust from falling inside the sill, thereby maintaining the aesthetic appearance. The purpose is to enable smooth opening and closing of the door.

[0007]

In order to achieve such an object, the elevator door according to the present invention has a cleaning member for removing dust existing around the sill so as not to fall into the sill. It is characterized in that it is provided in the vicinity.

Further, the present invention is characterized in that the cleaning member removes dust in a direction forming an obtuse angle with respect to the opening / closing direction of the elevator door and facing the outside of the sill. The present invention
Further, the cleaning member is axially moved as the elevator door is opened and closed so as to always face the above direction.

The present invention is also characterized in that the cleaning member rotates in a direction in which dust is removed toward the outside of the sill as the elevator door is opened and closed. The present invention is characterized in that cleaning members are provided on both front and back sides of the elevator door.

[0011]

In the present invention, the dust existing around the sill is removed by the cleaning member provided near the sill opening. This prevents dust from falling inside the sill, so compared to the conventional configuration in which dust once dropped inside the sill is removed with a brush, problems such as dust collecting at the ends of the sill occur. It will be difficult.

Further, in the present invention, the cleaning member removes dust in a direction forming an obtuse angle with respect to the opening / closing direction of the elevator door and facing the outside of the sill. By arranging the cleaning member in such a manner, it is possible to preferably prevent dust from falling inside the sill with a simple configuration. That is, such a configuration is easily realized by providing a brush under the elevator door so as to be located around the threshold opening and setting the posture of the brush. Further, by configuring the cleaning member to axially move when the elevator door is opened and closed, a greater cleaning effect can be obtained as compared with the case where the posture of the cleaning member is fixed.

In the present invention, alternatively, as the cleaning member, a member that rotates with opening and closing of the elevator door is used. For example, a cleaning member is provided, a part of which is in contact with the inner wall of the sill and therefore rotates as the elevator door is opened and closed. With such a configuration, a large cleaning effect can be obtained with a relatively simple configuration.

In the present invention, cleaning members are provided on both front and back sides of the elevator door. As a result, it is possible to preferably remove dust located on both sides of the threshold.

Further, in the present invention, holes, notches or recesses are provided around the sill so as not to communicate with the sill.
The dust removed by the cleaning member provided at the bottom of the elevator door falls into this hole, cutout or recess. Therefore,
The dust removed by the cleaning member will not be stored around the elevator door, for example, in the back of the basket chamber wall or the three-sided frame,
It will be easier to remove accumulated dust during maintenance and inspection.
