Conversion Between Lock Functions Using Lock Actuator

US Patent:

6758075, Jul 6, 2004

Filed:

Jun 6, 2002

Appl. No.:

10/164493

Inventors:

Randy L. Thwing - Las Vegas NV 89131

International Classification:

E05B 1100

US Classification:

70389, 70379 R, 70372

Abstract:

Methods, systems and apparatus for converting locks between key-retaining and non-key-retaining functions by means of a function-determinative lock actuator are disclosed. The disclosure teaches lock sub-assemblies that utilize a function-determinative actuator and a cooperating rotator bolt to transfer motion from a lock cylinder to a lock release mechanism. The function-determinative actuators can include movable portions that selectively determine the lock function by adjustment of the movable portion. Alternatively, changing the structure of, selectively adding portions to and/or removing portions from the actuator can determine the lock function. The disclosure also teaches dual-function locks that incorporate the above-noted lock sub-assemblies. Methods of converting lock functions using a function-determinative actuator are also disclosed.

Dual-Function Locks And Sub-Assemblies Therefor

US Patent:

RE38832, Oct 18, 2005

Filed:

Nov 12, 2002

Appl. No.:

10/292575

Inventors:

Randy L. Thwing - Las Vegas NV, US

International Classification:

E05B011/00

US Classification:

70389, 70 51, 70384, 70371, 70379 R

Abstract:

A dual-function lock in accordance with the invention has an axis-defining lock sub-assembly including first and second axially aligned rotator members having confronting first end faces and oppositely facing second end faces. The sub-assembly has a lost-motion recess and an anchor recess on one confronting face and one recess-engaging member extending from another confronting face to permit lock function selection by placing the recess-engaging member into a particular recess. Alternative dual-function lock sub-assemblies include a unitary rotator bolt and a companion actuator. The rotator bolt has a release-mechanism-engaging portion and an actuator-engaging portion. While a first section of the actuator-engaging portion permits limited lost-motion between the rotator bolt and a companion actuator, a second section prevents lost-motion. The lock function can be selectively determined by placing the companion actuator into the desired first or second section of the actuator-engaging portion.

Dual Function Padlock With Removable Cylinder Mechanism

US Patent:

5174136, Dec 29, 1992

Filed:

Oct 4, 1991

Appl. No.:

7/771650

Inventors:

Randy L. Thwing - Las Vegas NV

International Classification:

E05B 6722, E05B 1100

US Classification:

70 38A

Abstract:

A padlock with removable cylinder mechanism offers the user a choice of two distinct manners of operation or "functions"--a Key Retaining function and a Non-Key Retaining function. This dual function capability in a single unit is achieved by a rotator bolt bored to allow placement of a pattern of pins. A series of pins, which when installed in the rotator bolt in a specified pattern, causes the function selection to be accomplished. A re-keyable padlock which accepts widely available, standard dimensioned, generic key operated lock cylinders allowing the keying of this padlock to be adapted to the wide range of keying systems used in locks found in residential, commercial and other uses as required for security and convenience. The use of standard dimensioned cylinders in the padlock is accomplished by a cylinder retainer, tailpiece stop and rotator bolt which adapts the generic cylinder to padlock use. The cylinder retainer, which retains the lock cylinder in the padlock body, is in turn held in the body by a threaded screw which is accessible through the short shackle leg opening in the body only when the shackle is in the unlocked condition and swung clear of its body opening.
