DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic sliding door which opens and closes an opening and closing door at an entrance by driving a motor.

[0002]

2. Description of the Related Art An entrance and exit are provided in a partition wall, and a door body storage recess is provided on one side of the entrance, and a rail member having a length reaching the end surface of the door body storage recess is mounted above the entrance and provided on the rail member. 2. Description of the Related Art An automatic sliding door has been conventionally known in which a hanging vehicle provided on an upper side of a door body for opening and closing an entrance is placed and suspended on a substantially horizontal track, and the door body is suspended and the door body is opened and closed by a driving device. ing.

[0003] A drive device used in the above-mentioned automatic sliding door usually extends a timing belt between a driving pulley driven by a motor and a driven pulley, and connects a part of the timing belt to a door body. The door is opened and closed by forward and reverse rotation of the motor.

[0004] The driving device is supported by a rail member for guiding the movement of the door body, and is covered by an inspection cover provided to be freely opened and closed.

[0005] In the above-mentioned automatic sliding door, since the door opening the entrance is stored in the door storage recess, the door is not always exposed to the outside and its appearance is not good. Also, when the door was opened, there was a risk of injury due to contact with the door.

In order to solve such inconvenience, there has been proposed an automatic sliding door in which a door pocket is formed on one side of an entrance and an opened door body is stored in the door pocket.

[0007]

By the way, in a conventional automatic sliding door having a door pocket, a motor unit for rotating a driving pulley and a control box in which a control device for controlling the rotation of the motor of the motor unit are provided are provided. Since the configuration is arranged at the closed end of the door pocket, the maintenance of the motor unit and the control box requires the removal of the face panel forming the door pocket, making maintenance extremely difficult.

An object of the present invention is to provide an automatic sliding door which is easy to maintain.

[0009]

In order to solve the above-mentioned problems, according to the present invention, a door pocket is provided on one side of an entrance, and a rail storage space which is opened and closed by an inspection cover is provided above the entrance. In this rail storage space, a rail member having a length extending from the door end side of the doorway to the door end of the door pocket is attached, and the upper side of the door body that opens and closes the doorway is provided with the horizontal member provided on the rail member. A plurality of suspension wheels supported on the track are rotatably provided, and a mounting base formed on the rail member has a front surface facing the inspection cover,
A motor and a driving pulley driven by the motor are supported at the entrance of the door pocket, and a supporting base having one end facing above the entrance and a driven pulley corresponding to the door end side end of the entrance of the rail storage space. And a control box in which a control device for controlling the rotation of the motor is mounted between the pulley base and the support base by tightening screws. The drive pulley and the driven pulley It adopted a configuration in which a part of the belt passed between them was connected to the door body.

[0010] With the above configuration, by opening the inspection cover, it is possible to rotate the mounting screws of the support base that supports the control box, the motor, and the drive pulley from the opening of the rail housing space. Therefore, the control box and the support base can be easily attached to and detached from the rail storage space, and maintenance can be easily performed.

Here, two parallel guide grooves reaching both ends of the rail member are formed on the front surface of the mounting base formed on the rail member, and a pair of inward flanges are provided above and below the opening of each guide groove. By mounting each of the one end of the support base, the pulley base and the control box with a nut movably provided along the guide groove and a screw screwed into the nut, the screw is loosened to support the nut. Since the base can be slid to a position corresponding to the rail storage space, the support base can be more easily removed.
