Claims

[Scope of utility model registration request]

One end of each support arm is attached near the second side edge of the door in a direction intersecting the main surface of the door, and the other ends of the support arms are perpendicular to the garage side boundary surface. The door is supported by two shaft supports arranged on the first shaft, and when the door is lowered and the main surface of the door is vertical, it is at the closing limit, and when the door is raised and the main surface of the door is vertical, the door is at its closing limit. When it is horizontal, the door is limited to opening,
In a rotating elevator door, a biasing member that reduces the gravitational moment of a rotating part such as the door or a support arm is engaged between the rotating part and a structure that is integrated with the ground surface. The engagement of the rotating portion is performed when the biasing member protrudes directly or indirectly through another member such as a washer from the opening surface of the upper end of the column that supports the two pivot points on the ground. Or, as a preliminary work, a composite member that has been previously engaged directly or indirectly with a part of the rotating part and the biasing member can be attached to the upper end of the support. The opening at the upper end of the column is sealed by dropping it into the column from the opening surface, and the opening at the upper end of the column is sealed by inserting a housing member such as a lid into the column from above the column or from the inside side of the garage. The pedestal supporting the other end of the biasing member is also seated within the support column using the mounting screws only from the inner side of the garage. A rotating lift door featuring
