Claims (1)

[Claims for Utility Model Registration] 1. A door that is movably guided in the vicinity of the free edge of the inner surface of the door so as to be able to assume a locked position and an unlocked position along the front-rear direction substantially perpendicular to the free edge. It has a door stop bolt and a locking body provided inside the door frame so as to face the front end of the door stop bolt, and when the door stop bolt is in the locked position, the front end of the door stop bolt and When the locking body is engaged and the door is locked to the door frame, and the door stop bolt is in the unlocked position where it is not engaged with the locking body, the front end of the door stop bolt is inserted into the gap between the door and the door frame. In the case where the door is prevented from opening outward by straddling the door, there is a
An operating rod that penetrates this in the thickness direction and whose outer end is exposed on the outside of the door is rotatably supported, and an operating member perpendicular to this is integrally connected to the inner end of this operating rod, and the operating member is fixed to the normal position. A driving member is integrally provided on the inside of the front end of this operating member, and on the other hand, a stop member that engages with the driving member from the front is provided on the side of the door stop bolt opposite to the operating member, and a stop member that sandwiches the driving member. A driven part is provided which is formed behind the stop member and interferes with the rotation locus of the drive member, and under normal conditions, the unlocking position of the door stop bolt is determined by the engagement between the drive member and the stop member, and in case of an emergency. The operation lever is rotated to push the door stop bolt rearward through the sliding contact between the driving member and the driven part, so that the front end of the door stop bolt is pulled backward from the free edge of the door. A door stop lock device characterized by: 2. The doorstop locking device according to claim 1, wherein the operating member is a plate-like member having a substantially circular outer shape. 3. The door stop locking device according to claim 1, wherein the actuating member is an elongated rod-like member. 4. The door stop locking device according to claim 1 or 2, wherein the driving member is formed by bending one end of the operating member inward. 5. The doorstop locking device according to any one of claims 1 to 3, wherein the driving member is a pin implanted in the operating member. 6. The doorstop locking device according to any one of claims 1 to 3, wherein the driving member is a roller embedded in the operating member.
