TECHNICAL FIELD The present invention relates to an automatic sliding door structure.

[0002]

2. Description of the Related Art In many conventional automatic sliding door structures, a rail serving as a drive unit is attached to the lower surface of an upper frame (for example, Japanese Patent No. 2588122), but the height of the opening is as large as the size of the drive unit. There was a big problem that it would be low. In order to solve this, it is possible to consider the size of the drive unit and increase the height of the opening by that amount, but with the height of other openings that do not include the automatic sliding door structure. It is unrealistic because it loses consistency, the interior is unbalanced, and it feels strange.

For this reason, a structure has been proposed in which an automatic sliding door rail is embedded in the hanging wall above the opening. However, when maintenance and inspection or repair of the rail and other auxiliary devices such as a drive mechanism is performed, the lower side of the rail is I was only able to work from, and it was extremely difficult.

Further, when it is necessary to replace the rail itself, the wall portion in which the rail is embedded must be demolished, and the wall must be repaired after the rail is attached, which is troublesome and costly. Met.

Therefore, in addition to burying the automatic sliding door rail and other auxiliary devices in the hanging wall above the opening,
The mainstream at present is that a panel that can be opened and closed is attached to the wall where this is embedded, and that this panel is opened for maintenance during maintenance.

[0006]

However, the panel is made of a lightweight material such as plastic or aluminum to facilitate the opening and closing, which is different from the finish of the decorative board or cloth on the other wall portion. Therefore, it looks bad in terms of design.

Further, since the automatic sliding door rail is located at a high position above the opening, the maintenance work must be performed at a high place, which makes the work difficult.
