Abstract: In a device for the electrical connection of electrical or electronic components which are arranged on different sides of an electronic lock in pivotable or rotational operating members for the lock, which are connectable in a rotationally fast manner with a locking nose (6) of the lock via an interposed coupling shaft (3) passing through the lock, the coupling shaft (3) comprises an axial groove in which electrical wires or cables (1) are inserted. The coupling shaft (3) carrying the wires or cables (1) carries a sleeve (4) slipped on the coupling shaft (3) and reaching into a hollow shaft (7), the coupling shaft (3) is connected in a rotationally fast manner with the electrical or electronic components to be connected, or their boards, and the hollow shaft (7), which is connectable or connected with an operating member, operates the locking nose (6) for the lock and can be coupled to the coupling shaft (3) carrying the electronic components.

Abstract: In a security device for locks comprising a grip portion or knob (1) which is freely rotatable in the resting state and can be coupled to the locking member (7) of the lock in the open or closed state, a radially guided displaceable flyweight (13) is coupled to the grip portion or knob (1), which engages with a fixed portion (11) of the lock (12) and blocks any further rotary movement above a defined number of revolutions of the grip portion or knob (1) per unit time.

Abstract: In a device for securing the handle or knob (9) of a door or window, comprising a locking element (18) that is disposed transversely to the axis of the handle or knob (9), a locking spring element (13) is disposed in a base part or a knob shield (1), the locking spring element (13) carries locking lugs (8, 7) that dip into radial openings (2, 6) of the base part or the knob shield (1) the locking element (18) interacts with the locking spring element (13) in such a manner that the locking spring element (13) is deformed when the locking element is displaced transversely to the axis of the handle or knob (9) and locking lugs (8, 7), disposed on the periphery of the locking spring element (13), disengage from or engage with recesses (10) on or in a part of the handle or knob (9) encircling the locking spring element (13) and the base part or the knob shield (1).

Abstract: A deep longitudinally extending groove cut into a face of a key blade is either of isosceles-triangle or right-triangular cross section. In addition the face has a shallow longitudinally extending groove parallel to and offset from the deep groove and having a pair of generally planar narrow side flanks extending from the one side face to a common shallow apex line to give the shallow groove a triangular section. One of the narrow side flanks has a transverse width equal to generally half the transverse width of one wide side flank of the deep groove, and the other of the narrow side flanks has a transverse width substantially smaller than the transverse width of the one wide side flank of the deep groove.

Abstract: The device for electromagnetically blocking the closing cylinder (2) of a lock (1) includes a rotary drive comprising a coil (12) and a rotor (7). Depending on the rotary position of the rotor (7), the movable tumbler (4) may be disengaged from the recess (3) of the locking cylinder. In the blocking position, disengagement is prevented by abutment on the end face (11) of the rotor. (FIG.
