摘要:
The invention relates to an electrically operable locking device (400) for locking a gate (402). The electrical lock has a frame (200) for mounting the locking device (400) to the gate (402), and a housing (300) slidably movable with respect to the frame (200) between an upper position and a lower position and comprising a drop bolt (302) arranged to move between an extended drop bolt position and an retracted drop bolt position and a mechanical locking mechanism (301) arranged to lock and unlock the housing (300) to the frame (200) and comprising a key-operated cylinder lock (303) to unlock the housing (300) to the frame (200). The gate (402) is locked if said housing (300) is in the lower position and said drop bolt (302) is in the extended position. The locking device (400) further has a resilient element (309) positioned between the frame (200) and the housing (300) and arranged to lift the housing (300) relative to the frame (200) when the housing (300) is unlocked from the frame (200) by operation of the key-operated cylinder lock (303).
摘要:
Dans un même boîtier (1) sont montées coaxialement deux couronnes (2a, 2b) percées chacune d'un fouillot (10) recevant d'un côté une béquille extérieure et de l'autre une béquille intérieure en prise directe avec un pêne mobile. Les deux couronnes sont accouplées par une bille (3) placée dans un logement (13) prévu dans le boîtier. La bille se déplace, grâce à l'action d'un système magnétique commandé de l'extérieur, et se place dans une alvéole (12) commune aux deux couronnes pour les solidariser entre elles. Application à la protection des serrures de porte contre le vandalisme.
摘要:
The device includes a support structure (1) in which an assembly (21) of moving parts is mounted for movement along a predetermined direction and includes an electric actuator (23). This actuator is arranged to cause a control member (2, 3, 25) to move along the said direction in a working stroke, moving in one sense from a rest position to a working position and in the opposite sense to return to the rest position. Associated with this assembly (21-23) are two biasing springs (32, 33) and a releasable locking device (34, 41, 49) which is able to assume a normal locking condition, in which it holds the assembly (21-23) in a predetermined normal working position relative to the structure (1) against the action of the said springs (32; 33), and an emergency release condition in which it allows the assembly (21-23) of moving parts and its associated control member (2, 3, 25) to translate along this direction, in the opposite sense from the said first sense, for a distance at least equal to the said working stroke of the control member (2, 3, 25), under the action of the said springs (32, 33).
摘要:
A locking device comprising: (a) a tubular housing having a frontal end and a distal end; (b) a latch movable between a first position protruding from the frontal end of the housing and a second position wherein the latch is retracted in the housing; (c) electrically driven drive means for moving the latch between said first and second positions characterized in that said locking device further comprises a deactivation mechanism provided in said housing and allowing movement of the drive means or at least part thereof from an active position wherein the drive means are enabled to move the latch between the first and second position and a inactive position wherein the latch is retracted in the housing irrespective of its movement by the electrical drive means.
