Description

[Detailed Description of the Invention] The present invention relates to an automatic opening/closing door, and more particularly to a device for opening and closing the door.

Conventionally, automatic opening/closing doors have been installed so that they can be opened and closed along the upper frame or the upper horizontal frame that makes up the window frame, and drive parts such as motors, gear heads, pulleys, etc. are installed in the upper horizontal frame. and control section and driven pulley section,
A device is known that is equipped with a door opening/closing drive unit for a hanging door wheel.

However, with this structure, it is necessary to create a space below the drive unit for the door roller to run, which increases the dimensions of the upper horizontal frame and reduces the dimensions of the door mounting opening relative to the size of the window frame. In addition, the electrical wiring that electrically connects the control unit in the upper horizontal frame and the human body detector such as a matsu switch must be placed inside the upper frame through the vertical frame, which makes the electrical wiring troublesome. Since all the door opening/closing drive units are provided in a narrow space within the upper frame, a plurality of devices must be installed in the narrow space, making assembly, maintenance, and repair troublesome.

Additionally, there is a device known that allows the size of the upper frame to be reduced by not providing a space below the drive unit for the door roller to run; The problem is that the opening and closing operation of the door becomes unstable, and that it cannot be applied to narrow doors or heavy doors.

Therefore, as shown in Japanese Utility Model Publication No. 53-36747, it is known that the vertical frame is provided with a driving device and a driving pulley, and the upper horizontal frame is provided with a driven pulley.

However, with this structure, the driving pulley and driven pulley are installed vertically, so the chain is also vertically oriented, so in order to rotate the chain smoothly, the vertical space of the upper horizontal frame must be increased to some extent. However, there are disadvantages in that the dimensions of the upper horizontal frame cannot be made very small, and the connection structure between the drive device and the driving pulley becomes complicated.

The present invention was developed in view of the above circumstances, and its purpose is to reduce the dimensions of the upper horizontal frame, to enable stable opening and closing operations of the door, and to make it possible to open and close the door regardless of the door width or door weight. To provide an automatic opening/closing door which can be applied to any door and which can easily connect a driving part and a driving pulley.
