Abstract: A permutation lock comprises a housing having a rear wall and a front side closed off by a front plate. An axle extends transversely relative to a front-to-rear direction of the housing and carries rotary disks which project through slots in the front plate. A bolt is pivoted to the housing for rotation about an axis disposed parallel to the axle and situated immediately behind the front plate. The bolt extends rearwardly from the axis and has a locking portion at its rear end for engaging a hasp. Forwardly facing surfaces of the bolt engage and are cammed by the disks. The locking portion can extend through an opening in the rear wall and be shielded by a flap cut-out of the rear wall. Alternatively, the bolt can be V-shaped such that the locking portion extends from an apex of the V, the bolt is pivoted by one leg of the V, and the sensing surfaces are disposed on the other leg.

Abstract: A case comprises a pair of sections, one of which carries a hasp and the other of which carries a closure mechanism. The closure mechanism includes a hasp-receiving zone for receiving the hasp in a first direction, and a closure element for engaging and retaining the hasp in a terminal position in the hasp-receiving zone. The closure element is rotatably mounted on a pivot axle, and the pivot axle is movable in a second direction substantially parallel to the first direction. The closure element pivots on the pivot axle between a first position permitting the hasp to enter the zone, and a second position in which the hasp enters a recess in the closure element. By rotating an actuating lever, the closure element is moved to a third position retaining the hasp in a terminal position in the zone.

Abstract: A permutation lock is mountable on one section of a case and is adapted to secure a hasp carried by another portion of the case. The lock comprises a main housing in which a permutation setting mechanism is disposed. That mechanism includes a movable spring-biased locking element which is movable between a locking position and an unlocking position. A movable spring-biased locking bolt is arranged for rotation between a locking position for securing the hasp and an unlocking position for releasing the hasp. When the locking element is in its locking position, it prevents the bolt from moving from its locking position to its unlocking position. The bolt is mounted in an ancillary housing which is connected to the main housing at a rear end thereof, such that a wall separates the bolt from the locking element.
