DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator entrance / exit apparatus for improving a fire prevention treatment in a space between an upper frame upper surface and a ceiling of a three-way frame.

[0002]

2. Description of the Related Art Conventionally, in a building in which an elevator is installed, there is a building in which the distance between the ceiling on the landing side at the entrance of the elevator and the upper surface of a three-sided frame constituting the entrance is less than 30 cm. Some did not meet laws and regulations such as building standards.

[0003]

At the entrance and exit of the above-mentioned conventional elevator, it is necessary to provide a smoke-proof hanging wall, and when the smoke-proof hanging wall is provided, it is necessary to provide a good appearance. There was sex.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator entrance / exit device which has been made to satisfy the above-mentioned needs, has a simple structure, has a good appearance, and can satisfy laws and regulations concerning fire prevention.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a three-sided frame forming an entrance and exit of an elevator, and a landing door provided on the three-sided frame. An elevator doorway device having a dimension between the ceiling and the ceiling set to less than 30 cm, wherein the lower surface of the upper frame of the three-way frame is made of a non-combustible material and has the same color as the three-way frame. This is achieved by providing a hanging wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1 to FIG. 5, an elevator 1 comprises:
A hoistway 2 formed in a building or the like, a car 3 moving up and down in the hoistway 2, and a three-way frame 6 provided at an entrance 5 for allowing the car 3 to enter or exit a passage 4 in a building or the like.
And a landing door 7 provided in the three-sided frame 6.

The dimension G between the ceiling 9 of the landing 8 and the upper frame 6a of the three-way frame 6 is set to be less than 30 cm. The three-way frame 6 is made of a non-combustible material and is made of, for example, stainless steel in consideration of aesthetics. On the front surface of the upper frame 6a of the three-way frame 6, a smoke-proof hanging wall 10 is attached.

The smoke-proof hanging wall 10 is made of a non-combustible material and is given the same color as the three-sided frame 6. In the present embodiment, the smoke-proof hanging wall 10 is made of stainless steel so that a sense of unity with the three-sided frame 6 is obtained. Smoke-proof hanging wall 1
Numeral 0 is fixed by a plurality of fastening members 11 such that the upper end portion of the three-way frame 6 is covered. Smokeproof wall 10
Is set to be larger than a value obtained by subtracting a dimension G between the upper frame 6a of the three-sided frame 6 and the ceiling 9 from 30 cm.

As described above, according to the present embodiment, it is possible to form a smoke-proof hanging wall conforming to laws and regulations concerning fire prevention with a simple structure. The three-sided frame 6 has a smoke-proof hanging wall 1
Since it is only necessary to attach 0, it is not necessary to process a building or the like to which the elevator 1 is attached, so that it is possible to provide a smoke-proof hanging wall which conforms to laws and regulations, requires a short working time, is inexpensive.

In the above embodiment, the smoke-proof hanging wall 1
Although 0 is a single elongated plate, the present invention is not limited to this, and a structure that can expand and contract vertically may be used. Moreover, you may make it give a pattern, such as a picture which a passenger likes, on the front and back of the smoke-proof hanging wall 10.

[0012]

As described above, according to the present invention, an entrance / exit device for an elevator having a simple structure, low cost, and good appearance and which can form a smoke-proof hanging wall can be obtained.
