Abstract
A bolt-operated, vertical-lift lever lock having a lockcase or lock base and a lock cap, provided with a lever housing attached to at least one of the lockcase or lock base and lock cap and, wherein the lever housing is so constructed that the, or each, lever may slide within the lever housing and be protected against unauthorized lateral or longitudinal forces applied to the bolt.
Claims13
A bolt-operated lever lock having at least one lever operably connected to a lockbolt, said bolt-operated lever lock comprising:
- an exterior casing fixedly supporting therein a lever housing and having at least one bolt opening accommodating said lockbolt, and said exterior casing being securable to a desired object for facilitating securing of that object to a desired second object;
- said lever housing having an aperture extending therethrough and said lockbolt being slidably received within said aperture in a closely mating fashion, thereby permitting said lockbolt to be movable to and fro, relative to said aperture of said lever housing and said at least one bolt opening of said exterior casing, from an extended operative locking position to a retracted inoperative unlocked position, while preventing the lockbolt from being forced in a lateral direction relative to the bolt, thereby allowing said at least one lever to slide within the lever housing and be protected against at least one of unauthorised lateral and longitudinal forces applied to said lockbolt.
A bolt-operated, lever lock having an exterior casing at least partially enclosing a lever housing, with at least one lever being slidingly housed in said lever housing and being operably connected to a bolt, wherein said lever housing comprises:
- opposing first and second walls, each of said walls having an opening passing therethrough with said openings being in line with each other along an axis extending perpendicular to said walls, said bolt being slidingly received in said openings in a closely mating fashion,
- wherein the bolt is supported by the sides of said openings such that said bolt is prevented from being forced in at least one of a lateral and a longitudinal direction, relative to said bolt, within said lever housing, whereby said at least one lever may slide within the lever housing and be protected against at least one of an unauthorized lateral and an unauthorized longitudinal force applied to said bolt.
A vertical-lift, lever lock, having at least one lever for operatively engaging a lockbolt, comprising:
- a lock casing comprising a lockcase and a lock cap, a first aperture passing through one of the lockcase and the lock cap, with the lockbolt extending through the aperture;
- a lever housing comprising at least two, substantially parallel sidewalls fixedly mounted in the lock casing between the lockcase and lock cap, a first opening passing through at least one of the sidewalls, in line with the aperture, with the lockbolt extending through the opening;
- wherein the at least one lever is slidably mounted within the lever housing, such that the at least one lever is guided by the sidewalls of the lever housing as it is shifted from an operative position in which the at least one lever operatively engages the lockbolt, thereby preventing retraction of the lockbolt from an extended locked position to a retracted unlocked position, to an inoperative position in which the at least one lever is operatively disengaged from the lockbolt, thereby enabling retraction of the lockbolt from the locked position to the unlocked position, such that the lever housing protects the at least one lever from unauthorized forces and unauthorized observation, thereby prohibiting unauthorized picking and forceful unlocking of the lock.
