Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door contact device for a central double-door type elevator.

[0002]

2. Description of the Related Art FIG. 15 and FIG.
FIG. 15 is a view showing a conventional door stop device for an elevator shown in Japanese Patent No. 55571, FIG. 15 is a vertical side view of a hoistway, and FIG.
FIG. 3 is an enlarged cross-sectional view of a main part of a door contact portion (door closed state). In the elevator apparatus, as shown in FIG. 15, an air flow 32 often flows in the hoistway 31 in the direction indicated by the arrow or in the opposite direction.

The air flow 32 is apt to occur when a temperature difference occurs between floors due to air conditioning in the building or when outside air flows into the first floor of the building. Further, when the car 16 of the elevator travels, it is also generated by compressed air (positive pressure) generated in the front of the traveling direction and expanded air (negative pressure) generated in the rear of the traveling direction. Eventually, such an air flow 32 is generated in the gap between the doorstops of the landing door 2 and the landing doors 2 and 2.
It will flow into each floor through the gaps around it, and will flow into the hoistway 31 from the hall side. Also, in the elevator for observation, sunlight 33 also causes glass window 34
Will be incident on the floor of each floor.

In order to prevent such draft and light leakage, as shown in FIG.
Sealing members 4 and 4 formed of an elastic body such as rubber or synthetic resin are attached, and when the landing doors 2 and 2 are fully closed, the contact surfaces 4a and 4a of the sealing members 4 and 4 are in close contact with each other. The seal members 4 and 4 are configured so that no large gap is generated between them. However, in reality, it is difficult to make the clearance zero over the entire length of the landing doors 2, 2, and as shown in FIG.
Will occur.

In order to prevent the occurrence of such a gap δ, the elasticity of the seal members 4, 4 is increased to increase the elasticity of the seal members 4, 4.
Although it is conceivable that the seal members 4 and 4 are brought into close contact with each other, if the elasticity of the seal members 4 and 4 is increased, the seal members 4 and 4 become soft and easily deformed. Therefore, the position when the landing doors 2 and 2 are fully closed changes with the passage of time, causing another obstacle. Therefore, it is unavoidable that the minute gap δ between the seal members 4 and 4 is unavoidable. There is a surface attached.

[0006]

In the conventional elevator door stop device as described above, it is unavoidable that a small gap δ is generated between the seal members 4, 4 of the door stop tools 3, 3. A whistling sound is generated when the airflow 32 passes through the gap δ. This sound can be loud at times and is offensive to the ear. Although this sound changes depending on the size of the gap δ, there is a problem that the narrower the gap δ, the higher the sound and the more harsh the ear becomes. Also, sunlight 3
Similarly, No. 3 also has a problem that light is leaked from the gaps δ of the seal members 4 and 4 and the appearance is impaired.

The present invention has been made to solve the above problems, and provides an elevator door stop device capable of suppressing the generation of sound and light leakage due to minute gaps between the sealing materials of landing doors. With the goal.
