Abstract
An electromechanical lock includes a latching assembly secured to a first structure, a catch piece secured to a second structure, and an electromechanical device. The latching assembly includes at least one latch element movable between a capture and release states to mechanically engage and disengage the catch piece, an arming member movable between a first and second positions wherein the latch element is released and captured, and a biasing element to urge the arming member into the first position. When the electromagnetic device is switched “on”, it magnetically engages the arming member with sufficient force to overcome the biasing force whereby movement of the catch piece away from the received state results in the latch element moving into the capture state to prevent separation of the first and second structures; when the electromagnetic device is switched “off”, the first and second structures may be separated.
