Abstract: A mechanically operated lock which can operated by electrical control. The lock comprises a door handle rotatable door handle spindle (1) and a turn-knob or door handle rotatable turn spindle (2). The lock comprises a housing mountable or a door inner surface, into which said spindles (1, 2) extend. A mechanism (40) interconnects the spindles (1, 2) and is capable of engaging, by way of an electric control (5, 6, 7), the spindles (1, 2) with each other for a relative mechanical drive link, such that a rotation of the door handle spindle (1) translates into a rotational motion of the turn spindle (2) as well. The drive link (40) is adapted to decouple either automatically after a delay time or as the lock is opened by pressing the door handle. A piezoelectric actuator (20, 22, 23, 25, 26, 27), in a mode activated by an electrical control (5, 24), is adapted to immovably lock a bolt or plunger (27) which, in its immovably locked condition, couples said drive link as the door handle spindle (1) is rotated.

Abstract: The invention relates to a wirelessly controlled electric lock, comprising a lock body (2a), a key cylinder (2b), a turn spindle (3) rotatable by a handle element (3a) internal of the door, the turning of which enables opening of the lock, an opening spindle (4) rotatable by an opening element (5) external of the door, a drive link mechanism (41, 20, 21, 22) enabling the turn spindle (3) and the opening spindle (4) to be coupled with each other for a drive link engagement, such that turning of the opening spindle translates also into a turning motion of the turn spindle. The lock also comprises electrically controlled coupling elements (10, 21, 22, 24, 25, 26), including a piezoelectric actuator (10) which, in a mode activated by an electrical control (12, 31, 33) transmitted (32) wirelessly to the electrical lock, is adapted to fixedly lock a bolt or plunger (10a) which, in its fixedly locked condition, activates said drive link engagement as the opening spindle (4) is turned.

Abstract: An identification card holder, on the front side of which a replaceable identification card can be placed. A spring-loaded yo-yo is fastened and positioned on the reverse side of the holder, such that the yo-yo remains partially or completely invisible as the card, along with its holder, is viewed from the front side. As the yo-yo is integrated with the holder, the result will be a small-sized, readily portable, and easy-to-handle assembly, which can be distanced from a bearer to the proximity of a code reader for an electric lock without releasing the suspension.
