Patent number: 8312749Abstract: 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.

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.Type: ApplicationFiled: March 2, 2008Publication date: February 5, 2009Inventor: Moshe DOLEV

Patent number: 7334440Abstract: A door lock mechanism includes a rotatable spindle, an invertable tubular adapter, a doorknob and an interchangeable lock core. The rotatable spindle has a first longitudinal assembling slot, a second longitudinal assembling slot and a pair of retaining notches. The invertable tubular adapter has a third longitudinal assembling slot, at least one positioning protrusion and an upraised engaging block. During assembly, the third longitudinal assembling slot of the invertable tubular adapter and one of the first longitudinal assembling slot and the second longitudinal assembling slot of the rotatable spindle are aligned to receive the interchangeable lock core. The upraised engaging block is engaged with one of the first longitudinal assembling slot and the second longitudinal assembling slot of the rotatable spindle. The positioning protrusion is positioned in one of the retaining notches of the rotatable spindle to prevent any radial movement of the invertable tubular adapter in the rotatable spindle.Type: GrantFiled: November 13, 2006Date of Patent: February 26, 2008Assignee: Taiwan Fu Hsing Industrial Co., LtdInventors: Chiang-Lin Hsueh, Mei-Kuei Lee

Patent number: 7205492Abstract: 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.Type: GrantFiled: September 11, 2006Date of Patent: April 17, 2007Assignee: The Eastern CompanyInventors: Baltazar S.
