Filed:

Dec 4, 2003

Appl. No.:

10/728318

Inventors:

Barry G. Lawrence - Thomasville NC, US

International Classification:

E05C 3/04

US Classification:

292241, 292DIG 7, 292DIG 20, 292DIG 35, 292DIG 47

Abstract:

An improved locking device for sash-type windows is provided. The locking device includes a keeper defining an internal or keeper cavity, a housing defining first and second tier-recess combinations, a solid cam rotatively positioned within the first tier-recess combination, and a washer positioned between the housing interior and the flat top portion of the cam. The second tier-recess combination, or keeper recess, is defined by at least a portion of the housing that engages the keeper, such that the keeper is nestable within (wholly or partially enclosed by) the second tier-recess combination. Attempting to force the cam past the keeper cavity when the locking mechanism is locked results in the distribution of the force across the surface area of the keeper recess. The first tier-recess combination further defines an aperture for mounting a handle to engage and operate the cam.

International Classification:

E05C 3/04

US Classification:

292241, 292DIG 47

Abstract:

A locking window having a window frame and a window latch for use with the window is disclosed. The window latch, which is adapted to be attached to the window using a distinct fastener, is selectively movable between a first open position and a second locked position to secure the window sash in the closed position. The window latch includes an actuator arm, a locking arm, a non-compressible pivot and a housing. A pivot location is situated at the union of the actuator arm and the locking arm. The pivot location permits the actuator arm and the locking arm to be selectively movable between a first closed position and a second open position. The housing may include a securing feature for maintaining the housing substantially set relative to the window while at the same time permitting the actuator arm and the locking arm to be selectively movable between a first closed position and a second open position.

International Classification:

E05C 1/06

US Classification:

292 39, 292172, 292302, 49394

Abstract:

A rack and pinion are mounted on a casement window frame to operate a vertically disposed polymeric latch keeper. The moveable rack includes a plurality of teeth which are engageable with latch keepers spaced therealong. The pivotable window section includes latches which are rigidly affixed thereto. Thus when the window is closed a pinion can be rotated and thus drive the rack to engage the latch keepers into mating engagement with the latches for security and wind load resistance. The method of installation utilizes frangible spacers affixed to the latches for quick and easy alignment with the latch keepers.

Appl. No.:

11/136066

Inventors:

Barry G. Lawrence - Thomasville NC, US

International Classification:

E05C 3/14
E05F 1/00

US Classification:

292242, 292240, 292DIG 20, 292DIG 47, 49449

Abstract:

A security lock for sash windows includes an elongated cam that revolves in order to engage a keeper. The security lock also includes a tab that urges the cam against a wall of a housing to provide extra security. Once the cam contacts the housing wall it will not rotate to open as occurs in conventional sash locks. A groove and a race within the top inside of the housing direct a guide affixed to the top of the cam a), initially in a circular direction, and b), finally into a lateral direction into engagement with a locking stud on the wall of the housing. A rotating tab affixed to the handle axle causes the final cam movement during the locking process.

International Classification:

E05C 1/10

US Classification:

292175, 292DIG 47, 49449

Abstract:

A tilt latch for pivotable window sashes is preferably integrally molded from a durable polymeric material but can also be made from metals, metal alloys or the like. The latch includes an angled projection for engaging a recess in the window frame and includes a central body having a cavity for containing a coil spring. Upper and lower covers overhang the sides of the body to form channels for engaging the edge of the sash groove.

Abstract:

A security lock for a window jamb includes a pivotable stop for use on single hung, double hung and other type windows. The stop is manually operated to limit the window opening to about four inches to prevent unauthorized entry. The stop incorporates a lip which closes the stop opening to thereby prevent dust, debris and insect infiltration.
