摘要： A shape memory actuator is described. The shape memory actuator has a supporting body, a driven element slidably mounted on the supporting body for movement between a stable rest position and a stable operative position, a driving element that drives the driven element, the movement of the driving element being determined by a SMA wire and by first resilient return means acting to return the driving element to the rest position upon deactivation of the SMA wire, second resilient return means acting on the driven element in opposition to the SMA wire, engaging means suitable to achieve at the operative position a reversible engagement between the driven element and the supporting body, either directly or indirectly, said engagement being able to resist the action of second resilient return means, and a control system for the engagement and disengagement of the engaging means.

摘要： 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.
