Abstract: Disclosed is a window and lock assembly for releasably locking a sash component of a window in a closed position with respect to a frame component; wherein the lock assembly includes two catches mounted on said frame component at spaced apart positions. The catches are rotatably movable between locked and unlocked positions, wherein a slide bar connects the two catches. Rotation of the first catch causes rotation of the second catch, wherein in the unlocked position the first catch is rotationally closer to the first keeper than the second catch is to the second keeper.

Abstract: A joint structure for connecting framing components such as sash members for a window is disclosed having separate functional and decorative junctions between adjacent framing components. The functional junction between components may be formed between opposing and abutting mitered mating surfaces defined at adjacent ends of the component, and a separate squared flange and cooperative recess may be formed on interior surfaces of the components for overlapping the mating surfaces and providing a decorative junction, for example, having the appearance of a mortise and tenon joint. The joint structure is particularly suited for use in custom or replacement applications whereby lineal extruded members formed of a heat weldable material may be cut to size having the aforementioned surfaces, and then heat welded together to form a custom sized framing structures such as a sash or frame for a window or door.

Abstract: The present invention provides an assembly for extending the effective depth of a frame (510) secured within an opening having a depth greater than that of the frame (501-504) itself. A channel (515) is associated with each segment of the frame (501-504) and opens in the direction in which added frame depth is desired. Each channel (515) has a similar, half-dovetail profile (560), and a frame extending member (520) is associated with each channel. Each frame extending member (520) has a profile that includes a first portion (501) which is rotatable into engagement with a respective channel, and a second portion (650a) which extends in the desired direction when the first portion (501) is retained within the channel (515).

Abstract: The present invention provides a window screen having operators that secure the window screen relative to a window frame. A pair of single rail operators releasably secure the upper end of the screen relative to the upper end of the window frame. A pair of double rail operators releasably secure the lower end and sides of the screen relative to the lower end and sides of the window frame.

Abstract: A universal frame renders a double hung pocket replacement window suitable for window out--window in replacement and/or new construction installation, and likewise, renders a casement pocket replacement window suitable for window out--window in replacement and/or new construction installation, and likewise, renders a picture pocket replacement window suitable for window out--window in replacement and/or new construction installation, and likewise, renders a glider pocket replacement window suitable for window out--window in replacement and/or new construction installation, thereby giving rise to economies of scale in the manufacturing and distributing processes for a variety of windows.

Abstract: A corner lock includes a first member that is secured to a first window frame segment and a second member that is secured to the first member and a second window frame segment. The first member is inserted into an opening in an end of the first window frame segment, and a partial turn thereof anchors the first member relative to the first window frame segment. A ring on a protruding end of the first member abuts an end of the second window frame segment, and the second member inserts through this ring and is secured within the end of the second window frame segment.

Abstract: The present invention provides a window screen having operators that secure the window screen relative to a window frame. A pair of single rail operators releasably secure the upper end of the screen relative to the upper end of the window frame. A pair of double rail operators releasably secure the lower end and sides of the screen relative to the lower end and sides of the window frame.

Abstract: The present invention provides a double-hung window assembly having at least one sash slideably mounted within a frame. Elongate stops are secured along opposite sides of the slideable sash and are moveable between first positions interengaging a respective side of the frame and second positions free of engagement with the frame. When the stops are in their first positions, the sash is constrained to move in a linear path relative to the frame. When the stops are in their second position, the sash is free to pivot relative to the frame about pins or similar structure extending between the sash and the frame.

Abstract: The present invention provides a sash profile having a first channel that opens toward and receives a glass panel and a second channel that opens toward and is covered by the glass panel. The second channel and the glass panel cooperate to define a continuous passage about the perimeter of the sash.

Abstract: The present invention provides a mulling strip that interconnects a first window frame and a second window frame. The mulling strip includes structure disposed between the frames to prevent the frames from moving or deflecting toward one another, and structure that interengages the frames to prevent the frames from moving or deflecting away from one another.

Abstract: The present invention provides a variable angle wedge that supports a replacement window and compensates for whatever sill angle exists on the previous window frame. A flange opposite the variable angle extends between a window engaging member and a sill engaging member. The angle defined between the window engaging member and the sill engaging member can be decreased by removing a distal portion of the flange.

Abstract: Latching apparatus for first and second adjacent swinging doors prevents locking of the first door unless the second door is latched and prevents unlatching of the second door unless the first door is open.

Abstract: The present invention comprises a corner fastener for securing a first and second frame member together to form a corner of a frame. The corner fastener, in one embodiment, includes a first leg member cooperatively connected to a second leg member. Proximal sections of the leg members have raised surfaces which act as a pivoting point when the corner lock is utilized. In addition, the leg members have distal sections which are deformable, during installation, to assist in the alignment and adjustment of the mitre angle.
