BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator hoistway entrance / exit curing sheet for curing an entrance to an elevator hoistway.

[0002]

2. Description of the Related Art A conventional elevator hoistway entrance / exit curing sheet is provided with a window in a part of an opaque vinyl sheet material such as a canvas sheet, and a mesh sheet such as a net sheet is attached to the window to cover it. The entrance and exit to the elevator hoistway is cured by this cover, and the entrance and exit to the elevator hoistway can be visually confirmed from the mesh sheet portion.

[0003]

However, in the conventional elevator hoistway entrance / exit curing sheet, since the cover of the portion made of vinyl sheet material other than the window has no air permeability, the wind from the inside of the hoistway toward the hall side is not permeable. When it occurs, the above-described cover receives the wind and greatly expands toward the hall side or returns to the original state, and at that time, it may collide with the wall surface of the doorway and generate noise. In addition, although the conventional elevator hoistway entrance / exit curing sheet has windows in some parts, the rest is made of opaque material, so if you cover the entrance / exit, the inside of the hoistway will be dark, and work inside the hoistway For this reason, it was necessary to provide lighting devices everywhere. Further, from the construction worker in the hoistway, at a position close to the landing side of the cover, especially when trying to get out from the hoistway side, because the construction worker who is bending over and cannot see The elevator hoistway entrance / exit curing sheet sometimes collided with a construction worker at the landing.

An object of the present invention is to provide an elevator hoistway entrance / exit curing sheet which is transparent and transparent without being greatly swollen by the wind from the hoistway or generating a large noise. There is.

[0005]

In order to achieve the above object, the present invention provides an elevator hoistway entrance / exit curing sheet in which an entrance of an elevator hoistway is cured by a curtain-like cover, wherein the cover is a mesh. It is characterized by being composed of a sheet material.

[0006]

In the elevator hoistway entrance / exit curing sheet according to the present invention, since the cover is made of the mesh sheet material as described above, even if a wind heading toward the elevator entrance / exit from the hoistway is generated, the wind passes through the cover to some extent. Therefore, the cover will not be shaken by the wind and collide with the entrance / exit wall surface to generate a large amount of noise. Moreover, since the cover of the mesh sheet material has a certain degree of translucency and transparency, It is possible to take in the light to the hoistway and to easily see that there is a construction worker who is close to the cover, thus improving the safety.
