<p>Anti-panic control device for doors, comprising:
- a base structure (26),
- a spring latch (20) mounted rotatable relative to the base structure (26) around a main axis (38), the spring latch (20) being able to rotate between a closed position and an open position and being associated to an elastic element (39) which tends to maintain the spring latch in the open position, the spring latch having a slit (40) able to receive a retaining element (22),
- a first locking element (64) movable between an arresting position and a disengaged position,
- an actuating device (18, 28, 42, 44) able to move the first locking element (64) in the disengaged position, and
- a second locking element (68) movable relative to the spring latch (20) between an arresting position and a disengaged position, the second locking element (68) being thrust by elastic means (70) towards the disengaged position and being thrust towards the locking position by said retaining element (22), the second locking element (68) co-operating with the first locking element (64) in such a way as to lock the spring latch (20) in closed position when the first and the second locking elements (64, 68) are both in arresting position.</p> |
