Claims

[Claims for Utility Model Registration] 1. Gates 2A, 2B that can be swung open and closed are attached to fixed parts 1A, 1B that face each other in the opening width direction, and a lock 3 locks and holds these gates 2A, 2B in a closed position. is attached to the gates 2A and 2B with its operating tool 3A located inside the opening in the outward and outward direction, and at the same time, it is attached to the lower part of the inner surface of one of the gates 2A, so that it is vertically connected to the locking hole 4 formed in the ground. This is a structure for preventing lifting of a drop bar for a double door gate, which is provided with a holder 6 that supports a drop bar 5 that can be freely engaged and detached from any direction, and the drop bar 5 is placed in a locking position on the inner surface of the gates 2A and 2B. A structure for preventing lifting of a drop bar for a double-fold gate door is provided with a locking mechanism 7 that can be switched freely between a locked state and an unlocked state that allows the drop bar 5 to move upward to an unlocked position. 2. A restraining posture in which the locking mechanism 7 is located directly above the drop bar 5 in the locked position and abuts against and prevents the drop bar 5 from moving upward to the unlocked position, and the movement of the drop bar 5 is The structure for preventing lifting of a drop bar of a double-folding gate according to claim 1, which is configured to be able to switch freely between a restraining release position and a restraining release position where the door is evacuated from the route. 3. The lock mechanism 7 is provided on the drop bar 5, and when the drop bar 5 is in the locking position,
The structure for preventing lifting of a drop bar of a double-door gate according to claim 1, which is configured to be able to be freely engaged with and detached from the holder 6. 4. The lock mechanism 7 includes a lock lever 7A which is pivotally connected to the other gate 2B and is pivotable around the axis in the inward and outward direction of the opening, and the lock lever 7A is pivoted to a position directly above the drop bar 5 which is in the locking position. When the lock lever 7A is moved upwardly when the drop bar 5 is moved upwardly, the lock lever 7A is abutted and prevented from swinging upwardly. A structure for preventing the lifting of a drop bar of a double-folding gate as set forth in claim 2 of a certain utility model registration claim.
