A lock capable of automatically locking a door after closing includes a latch, an anti-theft latch, and a stop-latch. When the door is in an open position, the stop-latch is in an extended position to prevent the anti-theft latch from moving to an anti-theft position. When the door pivots to a closed position, the stop-latch moves to a retracted position, and the anti-theft latch moves to the anti-theft position. When the latch is moved to an unlatching position through normal operation, the anti-theft latch moves to a non-anti-theft position. Thus, the anti-theft latch will be in the anti-theft position when the door is in the closed position, and the anti-theft latch will move to the non-anti-theft position when the door is opened through normal operation.

A lock case with an anti-pick function is mounted on a door. The lock case includes a latch for retaining the door in a closed position. When the door is closed, an anti-pick latch of the lock case is in a retracted position to pivot an anti-pick member of the lock case to an anti-pick position, such that the latch cannot be picked to the latching position. When the door is not closed or a connecting member of the lock case is operated to actuate the latch, the latch can move to the latching position.

The present invention relates to a catch mechanism for blocking a bolt to prevent unauthorized opening of a door, the catch mechanism comprising a follower for operating a bolt between a locked state in which the bolt is extended and an unlocked state in which the bolt is retracted; a catch configured to block the follower for preventing movement of the bolt in the locked state, and a control member for operating the follower and the catch, The invention also relates to a locking device comprising such a catch mechanism.

A bolt lock comprises a lock body and a bolt which is lockable to the lock body. The lock body comprises a housing and a lock cylinder therein, a movable latch and a biasing spring. The housing comprises an introduction passage for the bolt. In a locking position, the latch engages a locking recess of the bolt and hereby locks the bolt. The biasing spring biases the latch in the direction of the locking position. The housing and the latch comprise a respective blocking section, wherein the blocking section of the housing and the blocking section of the latch are configured so as to engage with one another and hereby block the latch against movement from the locking position in the direction of an unlocking position, when a force, via the bolt introduced into the introduction passage, is exerted on the latch which is in the locking position, the force being counter to the introduction direction of the bolt. The biasing spring is oriented at an angle such that the biasing spring additionally biases the latch along the introduction direction of the bolt.

An exemplary apparatus includes a housing, a lock mechanism mounted to the housing, an electromechanical driver, a first override mechanism, and a second override mechanism. The electromechanical driver is mounted to the housing and is operable to unlock the lock mechanism. The first override mechanism is movably mounted to the housing and is operable to unlock the lock mechanism. The second override mechanism is movably mounted to the housing and is operable to unlock the lock mechanism. The apparatus has a first configuration in which a lock cylinder is engaged with the first override mechanism such that actuation of the lock cylinder unlocks the lock mechanism. The apparatus has a second configuration in which the lock cylinder is engaged with the second override mechanism such that actuation of the lock cylinder unlocks the lock mechanism.
