Abstract
A lock for cabinets wherein a lock component is attached to one element of the cabinet and a counter-locking component is attached to another element. The lock component includes a hook-shaped latching bolt which is slidable and swivelable to become engaged with and disengaged from the counter-locking component. The latching bolt is held in a latching position by a locking bolt part of a permutation lock, and also by a retaining mechanism in the form of a heart-shaped endless cam slot which effects a release of the latching bolt only in response to a displacement of the latter in a door-closing direction.
Claims26
A lock for a closeable member comprising first and second relatively movable elements, said lock comprising a lock component adapted to be mounted to one of said elements, and a counter-locking component adapted to be connected to the other of said elements, said lock component comprising:
- a housing having an opening;
- a latching bolt slidably mounted in said opening, said latching bolt including a rear end disposed in said housing and a hook-shaped front end disposable outside of said housing, said latching bolt being slidable rearwardly by said counterlocking component to a latching position in response to the closing of said other element wherein said hook-shaped end is placed in latching engagement with said counter-locking component, said latching bolt also being slidable forwardly to an unlatching position;
- means for swiveling said latching bolt in one direction during rearward sliding movement thereof to effect said latching engagement;
- means for swiveling said latching bolt in an opposite direction during forward sliding movement thereof to effect said unlatching;
- and
- a locking bolt for releasably engaging said latching bolt in said latching position.
A lock for a closable member comprising first and second relatively movable elements, said lock comprising a lock component adapted to be mounted to one of said elements, and a counter-locking component adapted to be connected to the other of said elements, said lock component comprising:
- a housing having an opening;
- a rigid one-piece latching bolt slidably mounted in said opening, said latching bolt including a rear end disposed in said housing and a hook-shaped front end disposable outside of said housing, said latching bolt being slidable rearwardly by said counter-locking component to a latching position in response to the closing of said other element, wherein said hook-shaped end is placed in latching engagement with said counter-locking component, said latching bolt also being slidable forwardly to an unlatching position;
- means for swiveling the entire latching bolt to move said front end in one direction during rearward sliding movement thereof to effect said latching engagement;
- means for swiveling the entire locking bolt to move said front end in an opposite direction during forward sliding movement thereof to effect said unlatching;
- and
- retaining means for preventing forward movement of said latching bolt out of said latching position, said latching bolt being releasable from said retaining means in response to rearward movement of said latching bolt.
A lock for a closable member comprising first and second relatively movable elements, said lock comprising a lock component adapted to be mounted to one of said elements, and a counter-locking component adapted to be connected to the other of said elements, said lock component comprising:
- a housing having an opening;
- a latching bolt slidably mounted in said opening, said latching bolt including a rear end disposed in said housing and a hook-shaped front end disposable outside of said housing, said latching bolt being slidable rearwardly by said counter-locking component to a latching position in response to the closing of said other element, wherein said hook-shaped end is placed in latching engagement with said counter-locking component, said latching bolt also being slidable forwardly to an unlatching position;
- means for swiveling said latching bolt in one direction during rearward sliding movement thereof to effect said latching engagement;
- means for swiveling said locking bolt in an opposite direction during forward sliding movement thereof to effect said unlatching;
- and
- retaining means for preventing forward movement of said latching bolt out of said latching position, said latching bolt being releasable from said retaining means in response to rearward movement of said latching bolt;
- wherein said retaining means comprises an endless cam slot carried by one of said latching bolt and said housing and a pin carried by the other of said latching bolt and said housing, an end of said pin being received in said cam slot;
- and
- wherein said pin is carried by said latching bolt and said cam slot is carried by said housing, said cam slot being disposed in a plate which is freely slidable in a direction transversely of the front-to-rear direction of sliding of said latching bolt.
