Abstract
Remote control locking and unlocking device, especially for an anti-panic bar, the displacement of which actuates the unlocking of a door or other exit opening means, of the type comprising a latch adapted to oscillate in rotation within a housing, wherein a lever arm comprises supplementary locking means adapted to cooperate with the cam outline of the latch in order to secure the latching rotation with respect to the lever arm when said arm is called into blocking position by the core of the electromagnet, such a control being applied to remote security locking of anti-panic bars.
Claims9
A remote control locking and unlocking anti-panic device comprising:
- a latch rotatably oscillating within a housing and including a first cam outline and a second hollow external outline, said second hollow external outline being adapted to conform with at least one part of a peripheral section of an anti-panic bar and adapted to mesh with said section in order to assume a position which blocks displacement of the anti-panic bar;
- and
- a lever arm having first and second ends articulated on a pivoting axle;
- an electromagnet means having a core connected to said second end of said lever arm for selectively maintaining said lever arm in a first position which prevents rotation of said latch;
- and
- supplementary locking means formed in said lever arm for locking rotation of said latch with respect to said lever arm when said lever arm assumes said first position;
- whereby energization of said electromagnet means causes said lever arm to pivot and be maintained in said first position;
- and
- whereby de-activation of said electromagnet means releases said lever arm from said first position, thereby enabling rotation of said latch and displacement of said anti-panic bar.
