A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.

The invention relates to a lock body having an electric motor. The electric motor is arranged to guide the forming and removing of a force transmission connection between the parts to be arranged in the force transmission connection to transfer force or to impede force transfer. If formation of the force transmission connection is not achieved, the construction of the invention is such that the use of one spring enables the pushing of the piston connected to the electric motor both outwards and inwards.

Handle device for operating doors, windows and the like. The handle device comprises a first element (3, 103), which is rotatable about an axis of rotation, a second element (8, 108), and a coupling device (10, 110) which is arranged to selectively allow and prevent relative rotation about the axis of rotation between the first and the second element. The coupling device comprises a first coupling member (11, 111) which is connected to or forming an integral part of the first element. A second coupling member (12) is connected to or forming an integral part of the second element (112). At least one engaging member (13, 13, 113, 114) is movable between an engagement position in which it simultaneously engages the first and the second coupling members to thereby prevent relative rotation between the first and second element and a release position in which it is disengaged from at least one of the first and second coupling members to thereby allow relative rotation between the first and second element. An actuator (22, 122) is arranged to move the engaging member between the engagement position and the release position. The engaging member (13, 14, 113, 114) is pivotally mounted to the first coupling member (11,111) and arranged to pivotally move between the engagement position and the release position.

An actuating assembly of a locking system (200) to operate a displaceable component of a latching system (210), includes: (i) a first member (24) which is connected or connectable to the displaceable component of the latching system (210); (ii) a second member (26), the first and second members (24, 26) being disconnectably connectable to each other, with the first and second members (24, 26) being in an inoperative configuration when they are disconnected from each other such that the second member (26) is displaceable independently of the first member (24), and the first and second members (24, 26) being in an operative configuration when they are connected to each other such that displacement of the second member (26) causes the first member (24) to be displaced; (iii) a first actuating sub-assembly (46) including a first key receiver (230) for receiving a non-mechanical first key in the form of a predetermined electromagnetic signal transmitted via a cellular telecommunications network from the communications facility (224) of a monitoring facility (227) to an electronic controller (228); (iv) a second actuating sub-assembly (52) which is operable by a second key (226), the second actuating sub-assembly (52) being operably connected to the second member (26) and being configured, when actuated by the second key (226), to cause the second member (26) to be displaced, thereby to cause the first member (24) to be displaced when the first and second members (24, 26) are in their operative configuration; and (v) a timer for determining the time from receipt of a first key by the first actuating sub-assembly (46), wherein the first actuating subassembly (46) is configured, upon: (i) receipt of the first key, to cause the first and second members (24, 26) to assume their operative configuration; and (ii) elapse of a preset time stored in a storage means (236) measured by the timer from receipt of a first key by the first actuating sub-assembly (46), to cause the first and second members (24, 26) to assume their inoperative configuration.
