  • Patent number: 9605455
    Abstract: A self-contained combination latch and cam lock adapter module affixes to the rear of any lock (keyed or non-keyed) that has a requisite mating feature. The module is alignable in any of four positions (up, down, left, and right) on the back of the lock for latching in any installed position. The module allows a user to slam closed an associated door or drawer without having to rotate the lock into a locked position. The module retrofits in the field by removing and replacing an existing fixed cam. In one embodiment, a mating part is rotationally spring-loaded so that when the key or knob is turned and then released, the module automatically returns to its locked position, ready to be shut.

  • Patent number: 8336348
    Abstract: Apparatus and associated methodology are provided for key operated pin tumbler locks, some of which may incorporate a removable core pin tumbler lock. A selected tumbler of a type commonly used in pin tumbler locks is configured along with a driver pin to control operation of a retainer that, when rotated by use of a control key inserted in the lock, allows alternate selective removal and replacement of the core assembly in the lock. Also, or separate therefrom, one or more tumbler holes may be formed or drilled in a manner so as to prevent engagement of a tumbler with the bite of a key. Presently disclosed structures and associated methodology help to reduce any susceptibility to unauthorized techniques practiced against the lock, such as unintentional activation of the tumblers by unauthorized persons through use of a key with so-called “bumping” techniques.

  • Patent number: 8312749
    Abstract: A lock and key mechanism reduces exposure to lock picking by including an extension into a key slot to receive and conceal tapered end portions of key pins. The only portions of key pins exposed in a key slot are cylindrical portions that are difficult to move from a resting position. A key includes a beveled leading edge and a spring-loaded pin activation element at the leading edge of the key. As the key is inserted into the key slot, the spring-loaded pin activation element is compressed to permit entry into the key slot. As the pin activation element reaches a pin, an aperture in the extension allows the spring-loaded pin activation element to move toward the key pin and move the key pin from its resting position. In this activated position, the tapered end portion of the key pin is exposed for further activation by the beveled leading edge of the key. The process is repeated until the pin activation element engages and activates each successive key pin and allows full insertion of the key.

  • Publication number: 20090031769
    Abstract: A cylinder lock having a body and a modified cam, the cylinder lock being adapted for moving an external element arranged to engage the modified cam, so that the external element slides axially on the cylinder lock body. In a preferred embodiment, the inventive cylinder lock is designed to utilize a helical cam which engages a movable external element or slider, and this design is referred to as the HC cylinder lock. When operated by rotating the appropriate key within it, the movable external element can be moved in a linear fashion along the length of the HC cylinder lock thus converting rotational motion of the key to axial motion of the external element. The external element is arranged to engage an eccentric pin formed as part of a rotating bolt which rotates on an orthogonal axis to the cylinder plug in response to said sliding motion, for the function of locking or unlocking a device.

  • Patent number: 7205492
    Abstract: A push button actuator unit has a housing which defines a through passage that extends along an axis of the housing, and a slot that extends in a plane which transversely intersects the axis and communicates with the passage for supporting in the housing-defined slot a disc-shaped member having a central opening that aligns with the passage. Movable in the aligned passage and opening is a push button sub-assembly of the unit which includes a front element that, when depressed rearwardly, may cause a rear element of the push button sub-assembly to extend rearwardly from the housing to release a latch or to operate a switch or the like. If the unit is to be lockable, an optional locking mechanism is added to the elements of the push button sub-assembly to selectively drivingly connect the front and rear elements so that depression of the front element will cause rearward extension of the rear element only when the unit is unlocked.
