Description

The present invention relates to a sliding door device having a self-closing function.

Conventionally, this type of sliding door device has a function of reducing the sliding door closing speed in the vicinity of closing to prevent a sudden closing movement of the sliding door, and as a means of gently closing the air cylinder (adjusting part side of the brake device) and air. It has a brake device composed of an operating protrusion for operating the cylinder.
Further, in order to improve the design, it is common that the surface other than the entrance is covered with the same decorative board as the wall surface of the building.
Furthermore, because the sliding doors of the sliding door device are installed after the interior of the building is completed, the sliding doors are attached to the rail material of the sliding door frame built in the building in advance from the entrance / exit, and then the sliding door sliding confirmation and closing speed are confirmed. Various fine adjustment work including adjustment is performed.

Furthermore, considering periodic inspections and repairs of malfunctions, it was necessary to consider that sliding doors, rail materials, etc. could be completely removed from the doorway.
For this reason, a detachable panel (so-called inspection panel) is constructed at the upper part of the inspection side (usually the indoor side) of the doorway, the sliding door is installed and the sliding door slide is opened with the panel removed and the upper front of the sliding door opened. After performing various fine adjustments including confirmation of movement and adjustment of the air cylinder (adjustment of the closing speed of the sliding door), the panel was attached to the upper part of the entrance again to hide the rail member, air cylinder, etc.
For this reason, since the above work is performed from the panel (so-called inspection panel) side, the air cylinder is a fixed part facing the panel and is installed above the rail member that has the least influence on sliding of the sliding door. Therefore, since it is necessary to conceal the rail member, the brake device and the like, the panel (so-called inspection panel) has been configured to have a considerable height. (For example, refer to Patent Document 1.)

For this reason, the design of the upper part of the entrance / exit is significantly different between the inspection side (usually the indoor side) and the fixed side (usually the outdoor side), and the surface other than the entrance / exit is covered with the same decorative board as the wall surface of the building. However, there was a problem that the design consideration of the entrance / exit portion was not sufficient while improving the overall designability.
