に配設したことを特徴とする回転昇降扉。 One end of the 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 arm are connected perpendicularly to the side boundary surface of the garage. 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 is configured to open only when is horizontal, between the support arm and a part of the support that supports the two pivot points relative to the ground, other than the pivot point, The links of the two-bar chain are engaged in a pivoting engagement at their respective ends, so that the support arm, the strut, and the link of the two-bar chain form a four-bar chain as a whole; The length of each side of the link of the two-bar chain shall be long enough to ensure the rotation distance of the support arm between the opening and closing doors relative to the respective pivot points, and the length of each side of the link of the two-bar chain at the opening limit shall be sufficient. Set the length of each side of the link of the two-bar chain so that the midpoint of the link is close to the door, and on the other hand, set the length of each side of the link of the two-bar chain at the closing door limit. A locking mechanism disposed between the links of the two-bar chain that fixes the inner corner of the door or the middle point of the link of the two-bar chain of the closing limit between the door or the support arm. A locking mechanism that immovably fixes the position,
A rotary lift door characterized in that the link of the above-mentioned two-bar chain is disposed on the door and/or the support arm.
