Abstract
A locking device includes a mobile locking member, movement of which can be prevented by a blocking member interacting with a motorized lever, where the motorized lever is capable of rotational movement about an axis with respect to the supporting structure, the centre of gravity of the lever lying on the axis, the lever being kept in a determined stable position and without rigid mechanical contact of the lever with the supporting structure apart from its axis of rotation.
Claims7
A locking device comprising a mobile locking member, the movement of which can be prevented by a blocking member interacting with a motorized lever, the motorized lever being capable of rotational movement about an axis with respect to a supporting structure, and a centre of gravity of the lever being located on the axis, and the lever being held in a determined stable position and without rigid mechanical contact of the lever with the supporting structure apart from the connection of its axis of rotation with the supporting structure.
An actuator for a locking device which drives a locking lever in rotation about a stationary axis, the locking lever has its centre of gravity on the stationary axis and the actuator comprises at least one magnet and has a variable air gap making it possible to ensure a stable position without any power consumption.
