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 side boundary surface of the garage. 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. In a rotating elevator door that can only open when it is horizontal, each of the pillars that support the two pivot points on the ground is divided into two members, an upper member and a lower member, and the upper member The above-mentioned shaft fulcrum is disposed on the upper member, and the upper member is fitted to the lower member so as to be slidable in the longitudinal direction, while a bracket piece is disposed on the inner surface of the lower member so as to be freely slidable up and down. The bracket piece and the upper member including the pivot point are spring-loaded with each other, and the support arm is disposed around the pivot point in the upper member. A cable or arm piece is placed between the co-rotating rotating wheel or tongue piece and the bracket piece in a direction that rotates the door, which is at the closing limit, in a direction that does not touch the ground surface when the spring is fired. The sliding contact between the bracket piece and the lower member is fixed so that the bracket piece and the lower member can be slidably connected and cannot be slidably connected by means of a mounting screw or the like from the outside of the lower member. The two modes are freely selectable, and when the bracket piece and the lower member are allowed to come into sliding contact, the upper member and the lower member are also not allowed to come into sliding contact, A rotating elevator door characterized in that the upper member and the lower member are connected to each other as an integral body.
