  • Patent number: 5010755
    Abstract: A torque-releasable door handle assembly is provided for operating a door-latching system. The door handle assembly includes a handle shell formed to include a hollow interior cavity having front and rear openings in the handle shell, a lock cylinder mounted in the hollow interior cavity to position its keyway opening in the front opening of the handle shell, and a torque-release mechanism interconnecting the handle shell and the lock cylinder. The lock cylinder is formed to include an axially extending, radially outwardly opening groove located in the hollow interior cavity. The torque-releasable mechanism normally extends into the groove to establish a driving connection between the handle shell and the lock cylinder. The torque-release mechanism is configured to disengage the groove temporarily to break the driving connection in response to the application of at least a predetermined amount of torque to a lever handle appended to the handle shell.

  • Patent number: 5009089
    Abstract: A double hook-bolt unit lock includes a lock barrel having a revolving rod connected thereto to cause a cam wheel assembly to move simultaneously so as to drive the stop keys of a stop frame assembly away from the upper notched portion of a brake frame assembly and to let the cam wheel assembly move the brake frame assembly rectilinearly via a lower notched portion of the frame assembly. By means of the push force from L-shaped guide slots of the side plates of a lockcasing and the guidance of oblique guide slots of a brake frame assembly, the two L-shaped bolts which are movably connected to the brake frame assembly are driven to smoothly into respective locking positions to lock the door.

  • Patent number: 5009090
    Abstract: A combination lock assembly for safes in which the combination can be easily reset without dismantling the assembly or changing its original adjustment for smoothness and consistency of tumbler wheel motion. The tumbler wheel and spacing washer components of the assembly are all mounted on a bushing that also includes an end cap. The tumblers and spacers are spring biased by a wave washer so that the drive tumbler, which includes a plurality of angularly spaced holes, presses against the end cap. One of the holes is aligned with a drive stud on the drive cam that is used to position the tumblers. In the event the drive tumbler should receive uneven pressure from the drive studs (e.g., due to improper alignment of the safe's drive spindle), the tumbler wheels and washers are all held together by the bias of the wave washer and are maintained with their engagement surfaces parallel with each other, permitting proper operation without undesirable wear.

  • Patent number: 5005393
    Abstract: A lock which is adapted to transduce the code from a key by electronic means is constructed to resemble the form and functionality of a conventional mechanical cylinder lock. A main casing houses the bolt, a rotatable thrower or cam for retracting the bolt, an electromechanical release mechanism which normally blocks rotation of the thrower, and a processor to control the release mechanism in response to the detected key code. The electronic reading means are located in association with the keyway of a rotatable barrel in a cylinder unit manufactured as a separate unit from the main casing. The thrower and barrel have respective cooperating mechanical couplings and the main casing and cylinder unit have respective cooperating electrical connectors. The lock is therefore assembled by attaching the cylinder unit to the outside of the main casing, thus establishing a rotary driving connection from the barrel to the thrower and establishing an electrical connection from the key reader to the processor.

  • Patent number: 5005387
    Abstract: A locking device for simultaneously locking two adjacent file cabinet drawers in a cabinet housing includes a locking mechanism mounted on a front face of one drawer. When a key is turned to actuate the locking mechanism, a cam, attached to the locking mechanism and positioned generally horizontally in a chamber formed in the first drawer, is rotated through a slot formed in a wall of the first drawer. Continued rotation of the locking mechanism rotates the cam through a slot formed in a mullion provided between the first drawer and an adjacent second drawer and into a slot formed in the second drawer to a generally vertical position for the cam. A central portion of the cam cooperates with the mullion and an end portion of the cam cooperates with the slot in the second drawer to prevent movement of the two drawers in the housing.

  • Patent number: 5005386
    Abstract: The principal purpose of this invention is to enhance locking and unlocking mechanisms of a padlock by improving structural components which allow the locking core member to be pushed into the lock body in order to trigger the locking mechanism by forcing locking plate and semi-circular sector thereof to be firmly engaged with locking notch located at the end portions of the U-shaped shackle arms. The unlocking mechanism can be triggered by simply rotating the locking core member with a key in one direction for 90 degrees, causing the locking core member and locking semi-circular sector to be disengaged. Therefore, this invention provides a padlock with improved safety features as well as convenience of ease of use.

  • Patent number: 5003799
    Abstract: An automatic shift lever locking device is capable of locking the shift lever of an automatic transmission in a specific non-driving shift position against movement from this position unless a predetermined condition is met. The device has a detent pin provided on the shift lever and movable in response to pressing of a push button on the shift lever, a movable member engageable with the detent pin, and a lock member engageable with the movable member so as to prevent the detent pin from moving out of a lock position thereby to maintain the shift lever locked in the non-driving position. Therefore, when the shift lever is not locked, the manual force exerted by the driver on the push button is not transmitted to the lock members and other parts mechanically connected to the lock member.

  • Patent number: 5003795
    Abstract: In one embodiment, a lock protector includes a front and back cover and a hinge portion formed from a single sheet of vinyl material. A hasp slot is formed in the back cover of the protector through which a hasp is inserted. The front and back covers include mutually contact adherent strips around the perimeter of the covers adapted to sealingly engage when the front cover is folded onto the back cover along the hinge portion with the lock situated within and attached to the hasp. Another embodiment is disclosed in which the lock protector includes a pouch defining a pocket for receiving the lock therein. The protector includes a flap extending from the pouch and adapted to overlay the opening of the pocket. The flap includes a hasp slot which is intersected by the hinge portion so that when the flap is folded over the pocket opening the hasp slot opens upward to receive the hasp. A number of contact adherent strips are provided on the flap for engaging the pouch and for engaging about the hinge portion.

  • Patent number: 5004198
    Abstract: A fixture-mounting post useful to mount one or more fixtures. An elongate member defines fixture-mounting means comprising two oppositely facing longitudinal arrays of fixture-mounting slots. An elongate shroud having two protions is disposed around the elongate member. For each array of slots, two elongate edges of the shroud extend between both ends of the shroud and are spaced from each other to permit access to such array. A sleeve encloses a portion of the shroud at one end. A strip of resiliently compressible material is wrapped at least partly around the member and is compressed between the member and the enclosed portion of the shroud. A tight fit thus is effected between the enclosed portion of the shroud and the sleeve to secure the shroud to the sleeve. A method of assembling the post is also described.
