Abstract: A tilt latch for pivotable window sashes is preferably integrally molded from a durable polymeric material but can also be made from other materials, for example metal and metal alloys. 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. An alternate embodiment of the tilt latch includes a body and a plunger containing a resilient member. A projection on the body engages a window recess. A resilient member is contained within the cylindrical plunger housing to prevent unwanted distortion and slippage.

Abstract: A framed window screen formed from four (4) rails which each include a channel, a wide groove and a narrow groove and are each cut at a forty-five degree (45°) angle at the terminal ends. A durable, sturdy corner connector joins each rail one to another, which may be molded from a durable polymeric material having an L-shaped member, a groove support and a stanchion. The groove support is V-shaped and joined to the L-shaped member by a rib. Each end of the L-shaped member of the connector is inserted into adjacent rail channels with the groove support positioned in the wide grooves of the adjacent rails. Once the screen frame is assembled using the connectors, a suitably cut screen wire can be placed over the frame with the edges proximate the narrow groove whereby a rubber seal is inserted to maintain the screen in the narrow groove by friction.

Abstract: A security lock having a housing and a cam. The housing includes an indent with a pair of guide portions. The cam is positioned within the indent and includes an axle port. A shaft of an axle is adapted to be inserted into the axle port so that the cam and the axle are rotatable together. The cam includes a sweep arm and a channel disposed on an upper surface of the sweep arm. The sweep arm has an outer wall that is either elongate-shaped or semicircular-shaped. The channel has a semi-circular-shaped inner wall and an elongate-shaped outer wall. Upon rotation of the axle, the cam rotates about the guide portions into a locked posture in the housing. The elongate-shaped outer wall of the channel allows the security lock to be self-locating when the housing and a keeper are misaligned when installed, respectively, on opposing window sashes.

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.

Abstract: The present invention relates to a casement window locking device having improved function, including improved strength, security, and durability. The invention provides a simple, elegant casement window lock having an extended operating range, is economical to manufacture, and uses few parts.

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.

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.

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.

Abstract: A latch mechanism is provided for a window which includes a top section and a bottom section with a surrounding groove therebetween. The groove may be varied in size depending on the particular sash header or base slot rail utilized. Different bottom sections can be employed which have flexible side walls of different heights to increase the versatility of the latch mechanisms. Tilt latch mechanisms can also be manufactured formed of a variety of different materials, with a variety of bottom sections having different side wall heights, some of which may be flexible.

Abstract: A guitar is provided with an easily replaceable neck which can be quickly and easily changed for another in the event of damage or for other reasons as desired. The neck is formed from a glass fiber reinforced nylon and includes a neck extension which forms a yoke for releasably bolting to the sound box. The sound box includes a groove for reception of the neck extension to insure correct alignment upon assembly.

Abstract: A closure mechanism for awnings and casement windows includes a flush, pivotal handle with a release mounted in a recessed housing. By depressing the release the handle is pivoted outwardly where it can be easily grasped by the user. Upon closing the window, depressing the handle allows the window to be tightly closed and latched within the frame as the handle is locked into a flush position on the window frame by a pawl which is resiliently urged into a notch in the handle within the housing.

Abstract: A shelf support is presented having a bracket with a base section including an opening for releasably securing a suction member. The suction member is formed from polyvinyl chloride and provides cushioning and gripping for a typical glass shelf.
