LOCK WITH EMERGENCY ACTUATOR
A lock for closing a door with respect to a frame. The lock includes lock body mounted on the door and a striker mounted on the frame, or vice versa. The lock body includes a catch element mounted so as to rotate between a striker keep position and a striker release position; elastic means suitable for driving the catch element from the striker keep position to the striker release position; a lever suitable for moving between two positions, a closing position in which it maintains the catch element in the striker keep position and an opening position in which it is disengaged from the catch element; and a service actuator suitable for applying a force f on the lever so as to bring it from the closing position to the opening position. The lock body further includes an emergency SMA actuator suitable for applying a force on the lever so as to bring it from the closing position to the opening position. The SMA actuator can apply a force higher than 100 N and including blocking means for allowing the force to be applied on the lever only when the force exceeds a predetermined threshold value.
