Abstract

Ratchet lock assemblies for use with various locking actuation members such as, but not limited to, lock cylinders of interchangeable core cylinder types are provided. In one embodiment, a ratchet lock assembly includes a plunger barrel with at least one projection extending therefrom. The at least one projection configured to mate with at least one aperture of a locking bar or strike plate to lock the ratchet lock assembly in place. In another embodiment, a ratchet lock assembly is provided with an anti-shim configuration to prevent unwanted removal of the ratchet lock assembly. The anti-shim ratchet lock assembly includes a driver and cam to lock a member, e.g., a spring, of the ratchet lock assembly to a locking bar or strike plate.

Claims20

Dependent claims

A locking device, comprising:

a housing including a first end and a second end, the housing extending from the first end to the second end along a longitudinal axis, the housing further including an outer wall defining a hollow interior of the housing;
a barrel including a first end and a second end, the second end of the barrel disposed through the first end of the housing into the hollow interior of the housing such that the barrel is slidable along the longitudinal axis, the barrel further including an outer wall defining a hollow interior, the first end of the barrel configured to receive a locking actuation member such that the locking actuation member is retained in the hollow interior of the barrel;
an elastic member to bias the barrel toward the first end of the housing;
and
a projection coupled to the second end of the barrel, wherein when the barrel is moved toward the second end of the housing, the projection is configured to mate with a locking bar disposed in the second end of the housing.

2 more elements

A locking assembly comprising:

a housing including a front portion and a rear portion, the front portion including an aperture revealing an interior of the housing, the rear portion including a recess;
a locking actuation member disposed through the aperture and mounted within the interior of the housing, the locking actuation member including a keyway;
a locking bar received by the recess of the housing, the locking bar including a serrated edge;
an elastic member configured such that, in an unbiased state, the elastic member selectively engages the serrated edge of the locking bar;
a first driver coupled to the locking actuation member and including a first cam;
and
a second driver including a first surface and a second surface, the first surface opposite to the second surface, the first surface including a groove configured to receive the first cam, the second surface including a second cam and a third cam extending therefrom,
wherein when an operating key is inserted into the keyway and rotated the first cam rides in the groove of the second driver to rotate the second driver and, when the second driver is rotated in a first direction, the second cam makes contact with the elastic member to bias the elastic member into the serrated edge of the locking bar securing the locking bar to the housing, and when the second driver is rotated in a second direction, the third cam makes contact with the elastic member to bias the elastic member away from the serrated edge of the locking bar to allow the locking bar to be withdrawn from the housing.
