Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric gate apparatus for driving an electric motor to open and close a passage, and particularly, by housing the door main body along a guide rail arranged parallel to the passage. The present invention relates to an electric gate device that can form a large passage portion even if the frontage of a site is narrow, because the width of the door storage portion formed at the lateral position of the passage portion can be reduced.

[0002]

2. Description of the Related Art Heretofore, there has been known an open gate door in which a panel-shaped door main body is attached to a suspension post through a hinge device so that the door main body can be horizontally rotated. When the door body is rotated toward the front of the operator, the operator must open and close the door body from a position outside the rotation range of the door body, especially when the operator operates from a wheelchair. The operation was extremely troublesome.

In addition to the above-mentioned open gate, if the door is a sliding door that linearly crosses the passage, the door body does not swing back and forth.
It is possible to open and close without worrying about the range of rotation of the door body, and the opening and closing operability is improved compared to an open gate. However, the sliding door gate requires a door main body storage space corresponding to the width of the door main body at a side position of the passage portion, which is unsuitable for construction in a narrow area. Further, in the sliding door gate in which a guide rail that regulates the moving direction of the door body is laid, the guide rail that crosses the aisle part is an obstacle to the passage of a wheelchair or the like.

The applicant of the present invention has improved the operability of opening and closing by reducing the pivoting space of the door body when opening and closing.
A door device in which a storage space for the main body of the door is arranged parallel to the aisle and does not require a storage space corresponding to the width of the main body at the side of the aisle is first proposed (Japanese Patent Application No. 2000-283
No. 047).

For the purpose of further improving the opening / closing operability of the door body, it is preferable to provide an electric drive device on the gate to automate the opening / closing operation. Japanese Patent Application 2000-28304
There has never been an example of incorporating an electric drive device into a gate that operates like the door device described in No. 7, and generally, when incorporating the electric drive device into the gate, a simple electric drive device is used. It is desired to have a compact appearance by using.

[0006]
