Description

The present invention relates to a revolving door.

Doors are widely used to cover the front surface of a storage space such as a shelf to protect the stored luggage, and to remove the coating as needed to facilitate the removal and storage of the luggage. As the door, a sliding door that slides left and right by a rail or the like and a revolving door that rotates about a rotation axis (in many cases, back and forth) are known.

The sliding door has an advantage that it does not require a moving space when opening the door, but friction occurs between the sliding door and the rail when sliding left and right, and the opening and closing of the door is not always light. On the other hand, the revolving door is easy to open and close, but since the door is rotated in the direction perpendicular to the door surface, it is necessary to provide a moving space for the rotation.

In this regard, Patent Document 1 discloses a lid opening / closing mechanism for rotating a door in a direction perpendicular to the door surface. According to such an opening / closing mechanism, it is possible to realize a revolving door that does not cause friction with the rail or the like and does not require a moving space when opening the door. However, in Patent Document 1, since the rotating shaft exists near the upper end of the door, it is difficult to support a door having a large weight in order to use it as a "door" instead of a "lid".
