Abstract: A one-piece metal frame fin is locked to the wooden frame members of a window unit by exterior cladding. A notch in the frame members receives the inner portion of the nailing fin while the outer portion of the fin is recessed into the wood when the fin is in its closed position for storage, transport and use in abutting frame members of multiple window units. An L-shaped corner nailing fin is carried on one of the frame fins and can be pivoted into locking engagement with the adjacent frame fin during installation of the window unit. In the case of joined multiple window units a mullion cover extends over the adjacent ends of the frame nailing fins and is locked to the outer nose portion of the exterior cladding. Use of foam sealing strips eliminates the need for on the job site caulking.

Abstract: A spring powered roll type fiberglass window screen has side edges received in guide channels in which locking bars are pivotally and slidably received. In closing the screen, the locking bars are longitudinally slidable by a screen actuator which in turn causes the locking bars to be pivoted into engagement with the screen by action of a guide actuator tab engaging a cam surface on the locking bar. In opening the screen, the screen actuator moves the locking bar upwardly until it is pivoted out of engagement therewith by a guide cam surface on the guide channel whereupon the screen is free to move to a fully raised position, leaving behind the locking bar.

Abstract: A casement window locking system includes a rotatable locking cam mounted in the frame jamb with a window catch access opening on one side and a locking lever access opening on the opposite side. The locking lever has a U-shaped inner end which embraces the locking cam when the two members are engaged and a tab on the locking cam engages a shoulder on the locking lever to prevent withdrawal of the locking lever until a tool is used to raise the locking cam when the tool is inserted through the catch opening. In an alternative embodiment, a spring clip may be placed on top of the locking cam and it includes a shoulder for engaging the shoulder on the locking lever. The removable locking lever makes it possible to install and finish the window without the locking lever and change locking levers to color coordinate with the room interior.

Abstract: A self draining door threshold includes a wedge-shaped silicone check valve in communication with a water reservoir on the interior side. The check valve is normally closed but will yieldably open in response to water pressure which overcomes the resilience of the silicone material and the air pressure on the top wall of the wege-shaped passageway. The check valve functions as a seal against incoming air but will open to allow escape of water as needed. The silicone material seals around foreign material in the valve making it air tight. The bottom edge of the door includes moisture resistant material having an upwardly extending portion received in a groove. The exterior side of the door is also covered with moisture resistant material which has inwardly extending portions received in a vertical groove between abutting panels.

Each component bar extends between opposite sides of the perimeter bar and has cooperating notches for engagement with the adjacent component bar which crosses it. A telescoping fastener with disc-like heads is received in a center opening at the intersection of crossing muntin bars and serves to lock the bars together and fill the space between the glass panes. The legs of a U-shaped retainer are received in the open ends of the component bars and are secured to the perimeter bar.

Abstract: A one piece flexible elastomer boot membrane flashing of EPDM extends from the roof upwardly around the wood base frame and over the top edge to provide a complete seal for a skylight window unit. A tape seals the outer edges of the outwardly extending peripheral lower flange portion of the boot to the roof. The skylight may be either of the fixed or ventilator type.

Abstract: A motorized window blind operator is slidably received in a mounting bracket in the plane of the blind in a window frame. A motor in the operator housing normally opens and closes the blind but can be overridden by a manually operated gear train utilizing a screw driver extending through a hole in the inner window pane into engagement with a slotted hub on a gear in the housing. An upstanding flange on the housing overlaps with the adjacent blind slat to prevent light passing therethrough when the blind is closed. The housing has a V-shaped vertical end which receives the ends of the blind slats which have a similar shape for preventing light passage therebetween.

Abstract: A double glazing panel including a pleated blind within, and means for raising and lowering the blind. One embodiment includes an aperture in one of the glazing panels, a bolt with a hole through the center mounted in the aperture, and the blind control means passing through the bolt hole and further up and over a screen, if desired. Another embodiment provides routing the control means over the glazing housing, and any screen housing provided. The blind may be optionally mounted to one of the glazing panels to aid in cleaning.

Abstract: A venetian blind support for a between-the-pane window blind includes an anchor clip secured to the bottom of the upper window frame rail detachably engaged by an anchor bar connected to the window blind by a rod-type hook. The support is self-centered in the window frame and the blind is self-centered as it is held by the support.

Abstract: A self-clamping spline and mortice joint is utilized at each of the corners of a rail and stile door. Mortices in each of the rail and stiles extend to the top or bottom edges of the door and a spline is received in the mortices and is exposed along the top and bottom edges of the door. Screws extend through the spline in opposite directions and into the rail and stile functioning to pull the rail and stile together around the spline. The self-clamping joint requires no external clamping. The self-clamping joint may be used on a plank-type door where the spline is L-shaped with one leg extending into the mortices and the second leg extending horizontally over the door and edges to cover the ends of the vertical grooves in the faces of the door. Weatherstripping on the door frame engages the horizontal leg of the spline and prevents transmission of air and moisture from the outside to the inside through the grooves.
