Appl. No.:

09/755921

Inventors:

Steven Armstrong - Anaheim CA

Assignee:

Newfrey LLC - Newark DE

International Classification:

E05B 100

US Classification:

16414, 16441, 16422, 292348, 292352, 292355

Abstract:

A quick install dummy doorknob or lever comprises an exterior knob sub-assembly, an interior rose liner coupled to the exterior knob assembly, a knob catch, a retainer spring, and an interior knob. The knob catch is disposed inside the interior rose liner and includes a tooth for engaging the interior knob. The interior rose liner engages a pair of screws extending from the exterior knob sub-assembly. Rotation of the interior rose liner relative to the screws places the screws into retaining apertures in the interior liner, whereupon the screws can be tightened to hold the interior rose liner in position. The interior knob is inserted into a recess formed in the interior rose liner and engages the tooth on the knob catch through a slot formed in the recess.

US Classification:

70492, 70383, 70384, 70493, 70495

Abstract:

A rekeyable lock cylinder includes a cylinder body with a plug body and carrier sub-assembly disposed therein. The plug body includes a plurality of spring-loaded pins and the carrier assembly includes a plurality of racks for engaging the pins to operate the lock cylinder. The racks and pins move in a transverse direction, in response to insertion of a first valid key into the lock cylinder, to unlock the lock cylinder. The carrier moves in a longitudinal direction, in response to insertion of a tool in a tool-receiving aperture, from an operating position to a rekeying position. In the rekeying position, the racks are disengaged from the pins and a second valid key can replace the first valid key. Rotation of the plug body from the rekeying position with the second valid key in the lock cylinder obsoletes the first valid key.

US Classification:

70492, 70383, 70384, 70493, 70495

Abstract:

A re-keyable lockset that employs pairs of first and second pins. Coupling of the first and second pins to one another defines a key profile for a mating key. A second key with a different key profile may be installed to the lockset when the first and second pins are uncoupled from one another. Thereafter, the first and second pins may be re-coupled to one another to define the key profile of a new mating key. A method for re-keying a lockset is also provided.
