Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic door device which is installed in an opening of a building and which opens and closes the opening by horizontally moving the door along the opening of the building. The present invention relates to an automatic door device that embeds a drive device and a rail member to improve the appearance of a wall surface of a building.

[0002]

2. Description of the Related Art A conventional automatic door device installed in an opening of a building to open and close the opening by horizontally moving the door along the opening of the building is a door that is suspended through a door roller to move horizontally. A drive device including a rail member for constraining the direction, a motor for moving the door, and the like is provided in the seamless space above the opening.

[0003]

However, when such a conventional automatic door device is installed in an opening of a building whose entire wall surface is covered with glass, a drive device for moving the door and a rail member are housed. There was a problem that the blindness above the opening was not harmonious with the all-glass wall and was very unsightly.

Therefore, in order to solve such a problem, it is considered that a drive device for moving the door and a rail member are buried in the pit under the floor to improve the appearance of the wall surface of the building. However, burying the rail member and the drive device, which are provided in the seamless space above the opening, in the pit under the floor causes various problems.

For example, water and dust are likely to collect in the pit under the floor, and when dust accumulates on the upper surface of the rail member, the door does not move smoothly. It has a problem that it may not move. Further, moving the door suspended from the rail member via the door roller and moving the door while supporting the lower part of the door cause a problem such as deterioration in stability when the door is moved.

The present invention has been made in view of the above problems of the prior art, and the object thereof is to embed a drive device and a rail member in a pit under the floor to build a wall surface of a building. The present invention aims to provide an automatic door device capable of improving the appearance of the door.

[0007]

SUMMARY OF THE INVENTION An automatic door device of the present invention for solving the above-mentioned problems is provided with a rail member which is connected to a lower portion of the door through a connecting member and horizontally restrains the movement of the door, and the door. In an automatic door device in which a drive device for moving along a rail member is embedded in a pit under the floor, an opening portion is formed in which the rail member and the drive device are slidable by a connecting member below the door protruding. It is housed in a storage case and / or is installed in the pit by installing the rail member and the driving device on a mount provided in the pit.

Further, a connecting member on one side of a lower part of the door, a rail member provided on one side of the lower part of the door for cantilever supporting the door horizontally through the connecting member, and the door as a rail member. A drive unit for moving along is embedded in a pit in the underfloor, and a door is installed on a guide rail having a concave cross section on a track on which an upper end of the door is slidably fitted, or
A groove portion is provided at the upper end portion, and the groove portion is guided and moved by a protruding portion on a track which is slidably fitted in the groove portion. Also, connecting members on both sides of the lower part of the door, rail members provided on both sides of the lower part of the door for supporting both sides of the door horizontally movable via the connecting members, and moving the door along the rail members. The driving device for driving is embedded in a pit under the floor.

[0009]

When the rail member and the drive device are stored in the storage case, dust and water are less likely to collect, and when the rail member and the drive device are provided on the pedestal, they are less likely to be immersed in water. Furthermore, a door that is cantilevered by a rail member and whose upper end is guided by a guide rail with a concave cross section or a protruding portion, or a door that is supported by both rail members on both sides and moves is stable during movement. Sex is secured.
