Abstract: A system for locking a position of an operable sash in a window frame has a motor, a rotating element connected to the motor, and a sweep cam. The sweep cam is configured to rotatably engage a keeper disposed on a sash disposed opposite the operable sash. A spur gear operatively connects the rotating element to the sweep cam.

Abstract: A constant force window balance system includes a mounting bracket defining a longitudinal axis, a coil spring, and a shoe. The shoe includes a first arm having a first inner surface and a second arm having a second inner surface. The shoe also includes a member extending between the first arm and the second arm. An opening is defined between the first inner surface, the second inner surface, and the member. The opening is configured to removably receive a portion of a pivot bar. The shoe is moveable between a locked position that prevents movement of the shoe along the longitudinal axis, when the pivot bar is not received within the opening, and an unlocked position that allows movement of the shoe along the longitudinal axis, when the pivot bar is received within the opening.

Abstract: A window balance may include a shoe body with an elongate portion and an enlarged portion. The elongate portion may include at least one carrier section for supporting a coil spring and an enlarged portion may include a locking element and a cam in communication with the locking element. The width of the enlarged portion may be greater than the width of the elongate portion. The spring may rest in the carrier section and may be secured to a window jamb with a fastener or a mounting element.

Abstract: A sash tilt system for an upper sash of a double hung window includes a mounting bracket sized and shaped to be fixed relative to a lower sash jamb pocket. A sleeve that is configured to be mounted on the upper sash, and a sash link including a first end and an opposite second end. The first end is rotatably coupled to the sleeve and the second end includes a post extending therefrom. The post is at least partially receivable within the mounting bracket such that the sash link is rotatable with respect to the mounting bracket and the sleeve when the upper sash tilts away from an upper sash jamb pocket.

Abstract: A window balance may include a shoe body with an elongate portion and an enlarged portion. The elongate portion may include at least one carrier section for supporting a coil spring and an enlarged portion may include a locking element and a cam in communication with the locking element. The width of the enlarged portion may be greater than the width of the elongate portion. The spring may rest in the carrier section and may be secured to a window jamb with a fastener or a mounting element.

Abstract: A sash cam for a window sash having a base adapted to be secured to a window sash, a cam positionable in a stored position and an engaged position, and a pivot for joining the cam and the base. The pivot is adapted to hold the cam in at least one of the stored position and the engaged position. When in the stored position, a depth of the cam is at least one of less than and equal to a depth of the base.

Abstract: A window opening limit device includes a substantially planar base and a sash stop pivotally engaged with the base between a first stop position and a second stop position. The sash stop is adapted to pivot about a first axis substantially parallel to the planar base. A catch is pivotally engaged with the base between a first catch position and a second catch position, and is adapted to pivot about a second axis substantially perpendicular to the planar base. When in the first catch position, the catch is engaged with the sash stop, and when in the second catch position, the catch is disengaged from the sash stop.

Abstract: A window insulation kit comprising a plurality of window covers sized to releasably couple to interior surfaces of an inhabitable multi-windowed vehicle and overlay those windows to create a light-tight and insulating covering of those windows. The basic kit includes the window covers, couplings, instructions, and implements used to assist in installing the window covers. The kit may also include one or more of an inhabitable multi-windowed vehicle, an electric heater, and an electric air conditioner. The kit may also include packaging having a transparent portion to allow the consumer to view the window covers. The window covers may bear decoration, advertising, or other designs. The window covers are preferably opaque in the visible and infrared spectrum.

Abstract: Disclosed are apparatus for a block and tackle window balance to be incorporated in single and double hung window assemblies. In one embodiment the block and tackle window balance includes a roller secured within a bottom guide to increase range of travel of a window sash.

Abstract: A slide block is provided for slideably and pivotally mounting a window sash to a side member of a window frame having a vertical window jamb channel. The slide block includes a body, the body defining a sash pivot-receiving aperture. A sash pivot retainer spring is integrally formed with the body and is positionable between a first position obstructing removal of a sash pivot when the sash pivot is disposed in the aperture and a second position permitting removal of the sash pivot.

Abstract: Disclosed are apparatus for a snap lock balance shoe and system to be incorporated in pivotable double hung windows. In one embodiment, the snap lock balance shoe includes a pair of retractable tabs that partially extend through openings within an inverted window balance.

Abstract: A security control verification and monitoring subsystem of a managed computer system performs security control verification operations regularly and for each security control verification operation determines the applicable security benchmark level for use by a given computer. The subsystem assigns security risk categories to groups of computers based, for example, on overall system or group administrator supplied potential impact settings and/or system type and business or information type selections. The subsystem further associates the security risk categories with security benchmark levels based on mapping information supplied by the overall system or group administrator. The subsystem then directs the computer to benchmark definition files based on the assigned security risk category, the associated security benchmark level and attributes of the computer.
