<p>A clutch mechanism for locks comprises an interior shaft (1) rotatably disposed in a static body (3), an exterior shaft (2) rotatably disposed in a cavity of the interior shaft (1), and a tumbler pin (4) and tumbler counterpin (5) slidably installed between an actuator (6) contacting the pin (4), and a spring (7) acting between the counterpin (5) and the bottom of a seat (2a) of the exterior shaft (2) for coupling the exterior shaft to the interior shaft. The actuator (6) comprises a spindle (6b) slidably installed in said body (3) and having an articulated connection to the tip of a first elastic arm (13) which has its other end radially fixed in a pivot shaft (14). One end of a second elastic arm (15) is radially fixed in this shaft (14) and has its other end meshing with a worm screw (16) driven by a motor (17).</p> |
