Abstract: The invention relates to an electronic padlock cover with a knob, wherein the padlock includes a rotor assembly formed by an electronic cylinder joined in continuity to an electronic knob, a body wherein the cylinder and a padlock ring are housed, wherein the cover includes a protective casing of the body intended to surround and protect the body of the padlock on one end, a support with a ring-shaped configuration including two grooves and an extension, centered on each groove, which includes a pair of first holes for the introduction of corresponding fastening screws for fastening to the body of the padlock and a protective casing of the knob including two flanges located in correspondence with the grooves, including an inner cylindrical opening for the housing of the knob.

Abstract: The present invention relates to a symmetrical and reversible-clutch mortise lock comprising a central follower, a pair of symmetrical lateral followers, each one located on one side of the central follower to be activated by square bars of handles, a spacer which makes the movement of the two lateral followers independent and a motor, which connects to an actuation lever and which is activated when an access code is validated. The lock further comprises a clutch housed and guided in an accumulator arm able to move linearly to be housed in both lateral followers such that the corresponding lateral follower, when activated by the motion of the door handle, pushes the clutch until it makes contact with the central follower and activates the latch of the lock.

Abstract: An improved clutch mechanism for electromechanical lock cylinders is disclosed. The aim of the invention is to improve the performance of the clutch mechanism and to increase the battery life of the motor which is included in the electromechanical lock cylinder. The improved clutch mechanism comprises an electromagnetic motor (2) with a threaded spindle (3) on its shaft; and a movable cart (4), which comprises a resilient device determined by two front springs (26) joined together at one of their ends by a common transverse portion (26?) engaged in a valley of the spindle (3) thread, which moves the movable cart (4) by means of the common transverse portion (26?) between a disengaged position and an engaged position, such that in both positions the common transverse portion (26?) carries out a continuous thrust on the spindle (3).

Abstract: A clutch mechanism permits a pulling movement to be transferred or not to the bolt of a lock when turning the internal or external handles attached to separate square-section shafts belonging to clutch elements and which can have independent rotation or they can do so integrally. A first clutch element connected to the outside handle possesses a prismatic projection with a radial orifice into which fits a pulling pin assisted by a spring and which is able to be displaced in order to be introduced into a slot of a second clutch element. The movement is controlled by a motor with a worm-screw linked to a spring which can displace a thruster rocker arm which makes contact with the pulling pin. The mechanism also includes an emergency device having a rod and another spring linked to the thruster rocker arm.

Abstract: It comprises a carriage (4) displaceable forwards and backwards by means of a spindle (3) actuated by a motor (2), the carriage (4) containing clutch pins (12) so that in the forward displacement the engagement takes place with a clutch disc (22) integral with which is an eccentric, whose rotation will cause the actuation of the lock in which the unit is fitted. In its displacements the carriage (4) is guided in rods (8) provided in the corresponding cover (5) of a rotor (1) in which the motor (2) and carriage (4) assembly is housed. The clutch pins (12) are connected to pushing springs (13) for pushing them towards the emergency position and therefore that of engagement when those pins (12) are facing the holes (23) of the disc (22).
