段動作回転昇降扉。 One end of the support arm is attached near the two side edges of the door in a direction intersecting the main surface of the door, and the other ends of the support arms are connected to one end perpendicular to the side boundary surface. When the door is lowered and the main surface of the door is vertical, it reaches the closing limit, and when the door is raised and the main surface of the door is horizontal. In a rotating lift door that is designed to open only when It is suspended between the moving part and the ground and an integral structure such as a column that supports the above-mentioned shaft supporting point to the ground, and the point of discontinuity in the load characteristics of the above-mentioned gas spring is at the closing limit during normal use when opening and closing the door. The rotation of the rotating part further downward from the closing limit during normal use of the door is limited in accordance with the displacement of the gas spring in the high load and high spring constant range. A two-stage rotating lift door.
