Abstract (en)
The spring latch actuation device in locks operated by magnetic cards comprises a plate-like element (6), which is constantly connected to the spring latch, and a disk-like element (17) , which is connected to the spring latch actuation knob (33). The disk-like and plate-like elements are supported so as to be able to rotate coaxially with respect to one another. A rocker lever (21) is articulated on the disk-like element (17) and is suitable for engaging a notch (8) of the plate-like element (6). The lever (21) is retained, by spring means (10, 11) which are accommodated in the plate-like element (6), in a passive position which corresponds to the free rotation of the knob. When a magnetic card (42) is inserted in the reading device of the lock, an appropriately provided electromagnet (36) is activated so as to rotate the lever (21) into an active position in which the lever engages the notch (8) of the plate-like element (6) so as to provide the rotational coupling of the plate-like element (6) with the disk-like element (17) and allow the actuation of the spring latch when the knob (33) is acted on. <IMAGE>
