DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide gate in which an entrance is opened and closed by a slide door provided at a frontage of a site.

[0002]

2. Description of the Related Art Conventionally, in such a slide gate,
A sliding door having a width substantially the same as that of the door pocket is slidably juxtaposed with respect to a door pocket provided for accommodating the sliding door on one side of the site frontage, and is a remaining portion of the door pocket installation portion at the site frontage. Although the entrance is openable and closable, the door pocket and the sliding door must be in an overlapping state when the entrance is closed, so the width of the door pocket is slightly wider than the entrance width, that is, the entrance width is at most half of the site frontage. In modern residential land, the frontage of the site is very narrow, so that the width of the entrance is inevitably narrow with the gate having the above configuration, and it is particularly difficult for a car to enter and exit.

Therefore, a telescopic gate has been developed in order to secure a wide entrance, but such a telescopic gate has a complicated structure because it is mainly constituted by linking rods by linking pins with each other. Therefore, it is difficult to open and close smoothly because the pin is easily exposed to wind and rain and the movement of the pin joint is likely to deteriorate.

[0004]

An object of the present invention is to provide a slide gate which can secure a wide entrance, even if it is a slide type gate, has a simple structure, has few troubles, and enables smooth opening and closing. It is.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the problem that a one-piece slide gate cannot secure a wide entrance according to the above-mentioned prior art, and the door pocket is installed on one side of the entrance to the site. A plurality of sliding doors having the same width are arranged side by side, and the doors are opened and closed by the sliding doors, thereby enabling opening and closing of wide doors even if the width of each sliding door is narrow, that is, a site occupied by a door pocket. The ratio to the frontage is reduced.

In addition, in the conventional telescopic gate, in view of the problem that a failure easily occurs and smooth opening and closing is difficult, a guide rail fixed to one side of the adjacent door pocket and the sliding door and the guide rail and the guide are fixed. Solving the above problem by making each slide door slidable with respect to the adjacent door pocket and slide door with a simple structure provided with a slide rail slidable on the rail and a connection portion with the slide rail on the other side. It's a neat thing.
