摘要： A door lock comprises a driver hub connected to a door lever, a driven hub, a latch lever movable by the driven hub for retracting the lock's bolt to open the lock, and a catch mechanism for selectively connecting the driver hub to the driven hub. The catch mechanism includes an idle position in which the driver hub moves without moving the driven hub and an engaged position in which the driver hub moves the driven hub and thus the lever and the bolt. A state selection mechanism is provided to displace the catch mechanism between its idle and engaged positions. An actuating mechanism, e.g. a solenoid, selectively positions the state selection mechanism such that the latter causes the catch mechanism, when driven by the driver hub, to adopt one of its idle and engaged positions such that the catch mechanism respectively drives, or not, the driven hub. The actuating mechanism thus allows the state selection mechanism to mechanically cause the catch mechanism to selectively connect or disconnect the driver hub from the driven hub and thus to respectively unlock or maintain locked the door lock. The actuating mechanism typically allows the state selection mechanism to position the catch mechanism in its engaged position, i.e. in its door unlocking position, when activated by a current which results from a valid entry having been recorded in an electronic access control system, or the like.
