Abstract: An insulated glass window with an integral blind assembly. At least one of the glass spacer corner keys includes an integral pulley for cords associated with the blind. An operator on an exterior surface of the glass includes a leg slidably retained between the frame and the glass to maintain the operator in contact with the window and the blind mechanism enclosed therein.

Abstract: A penetration resistant doorlight including a frame and a laminated window assembly. The window assembly includes a glass panel laminated to a security film such as P.E.T. The security film extends beyond the perimeter edge of the window assembly to overlap the door. The film is secured both to the frame and to the door. In the preferred embodiment, a reinforcing insert is included in the frame and overlaps all of the window, the door, and the film.

Abstract: An improved insulated glass including a spacer unit and a pair of glazing panels bonded to opposite sides thereof. The spacer unit includes a peripheral spacer portion and a muntin portion within the spacer portion. The spacer unit is a one-piece, injection-molded unit, and consequently the spacer portion and the muntin portion form an inseparable integrated whole.

Abstract: A doorlight shade assembly including a housing, a roller shade within the housing, and a pair of mounting clips. The clips each include a secured leg and a supporting leg perpendicular to each other. The secured leg of each clip fits between the door and a doorlight frame. The supporting leg of the clips receive and support the housing.

Abstract: A blind assembly having a frame entrapping a set of blinds. The frame has an integral track upon which tilt and height control mechanisms are slidably mounted. A height control mechanism is slidably mounted on a vertical portion of the track, and the blinds are raised and lowered by movement of this mechanism. The mechanism is connected to a lift cord retained within the track and hidden from the user's view. This mechanism further includes a spring lock to engage the track and lock the mechanism, and thus the blinds, in a stationary position. A tilt control mechanism is slidably mounted on a horizontal portion of the track, and the blinds are opened and closed by movement of this mechanism. The blinds are protected behind a pane of glass or clear plastic.

Abstract: A tubular skylight having an improved dome improving the efficiency of the skylight and reducing the shadows cast by the skylight. The dome includes a substantially vertical rear face having an integral prism in a portion of its outer surface, and the rear face is offset inwardly from the perimeter of the reflective tube, thus allowing light to escape from the bottom edge of the rear face downwardly into the reflective tube. The integral prism does not extend to the top or front face of the dome, thus reducing the prevalence of shadows created by light rays entering the dome through the prism.

Abstract: A penetration resistant door light adapted to withstand impact from flying debris as might occur in a hurricane or other high-wind condition. The door light includes inner and outer frame halves that support a panel assembly within an opening formed in a door. The panel assembly includes a sheet or layer of transparent impact resistant material such as a polycarbonate or laminated glass. The impact resistant sheet is structurally secured to at least screws extend through all of the inner frame half, the impact resistant sheet, and the outer frame half. In an alternative embodiment, a structural adhesive intersecures the impact resistant sheet and the outer frame half.
