The blocks are secured serially to the flexible frame member. The blocks and flexible frame member form a subassembly which is secured to the rigid frame member such that the subassembly assumes the curved profile of the rigid frame member. The blocks are preferably wood, the rigid frame member preferably an aluminum clad frame cover, and the assembly preferably provides an aluminum clad, wood core window frame assembly.

Abstract: A rolling window screen assembly is provided for a window frame having a sill, a head and opposite side jambs. The screen assembly comprises a screen mounted at the head of the window frame and being unrollable along the jambs thereof. A pair of guide members are mounted on and extend along each side jamb for guiding the opposite edges of the screen as the screen is unrolled along the jambs. Control levers adjacent each side edge of the screen frictionally engage the guide members so as to control the position of the screen along the guide members. The guide members are mounted to the window frame jambs by a plurality of L-shaped clips which extend through a corresponding slot in the respective guide members. A spring is positioned in each guide member for centering the unrolled screen between the pair of guide members.

Abstract: A thermal and moisture resistant door comprises a perimeter framework with a laminated skin glued to the interior and exterior sides of the framework, with an insulative core material therebetween. Laminated panels are secured to the skin on one or both sides of the door to provide the desired decorative appearance. Each skin and panel includes at least one cross-banding layer, a vapor barrier layer, and an outer veneer layer. Each panel is routed or molded such that an intermediate wood layer is visible, while the remaining layers of the panel are substantially concealed.

Abstract: An improved casement window securement mechanism includes two cams, one handle, cam linkage and a cam and linkage supporting spacer. The spacer supported cam is a reaching cam including a cam ramp with a straight drawing portion, and cam center and over-center portions. The reaching cam draws a catch at a rate varying with the cam angle of rotation. The securement mechanism draws and positively secures a bowed or warped casement sash.

Abstract: A room addition type of construction for attachment to the outside wall of a building. The wall has an opening for access to the interior of the building. A foundation is provided adjacent the wall and an upright frame assembly is mounted on the foundation. The frame includes side wall frames, an outer wall frame, and a roof frame. A plurality of structurally independent panel members are securely mounted in each of the frame portions with a substantial portion of the panels comprising window units having glazing panels therein. The panel members cooperate with the frame assembly for providing load bearing support for the structure. The frame assembly is secured to the building and a weather seal is provided between the room structure assembly and the building. The panels are secured to each other and to the frame assembly and weather seals are provided between the panels and between the panels and the frame assembly.

Abstract: A door assembly is provided and generally includes a door frame having a door hingedly mounted on one of the jambs of the frame. The door includes stiles and rails with double glazing panels mounted between the stiles and rails with an insulating air space between the glazing panels. First and second weatherstripping members cooperate with the door and jambs of the door frame to provide substantially air-tight and water-tight seals, respectively, when the door is closed within the frame. The first and second weatherstripping members are spaced apart so as to define a weatherstripping air space therebetween. The door includes passages for providing communication between the insulating air space and the weatherstripping air space so as to minimize condensation between the glazing panels.

The panel members cooperate with the frame assembly for providing load bearing support for the structure. The frame assembly is secured to the building and a weather seal is provided between the room structure assembly and the building. The panels are secured to each other and to the frame assembly and weather seals are provided between the panels and between the panels and the frame assembly.

Abstract: In a frame and movable panel assembly, such as a ventilating skylight, a weather seal comprises a panel cap on the panel, a projection on the frame and a water dam on the projection. The cap defines a covered recess into which the projection enters upon closure of the panel on the frame, to provide a primary air tight seal. The dam simultaneously contacts the cap to provide a secondary water tight seal which protects the primary seal.

Abstract: In principal aspect, a double glazing panel gasket includes a compressible central gasket portion and a fin portion. The central gasket portion provides a moisture-tight seal between a double glazing panel frame and a sash glazing stop, under compression. The fin portion simultaneously applies pressure against the panel, in response to the compression, to provide a moisture-tight seal between the panel and the stop.

Abstract: A casement window is operable in a vent-egress mode and a wash mode. Hinge assemblies are mounted to the sash and hinge lock assemblies are engaged by the hinge assemblies. Both hinge and hinge lock assemblies are slidably mounted to channel-forming slides on the window frame. The lock assemblies releasably lock the sash in the vent-egress and wash modes.

Abstract: An improved method and assembly for cladding an existing, exterior window frame. Frame expander receptors are fastened to the window frame head and jamb members. Frame expanders are retained in receiving recesses of the receptors. Cladding portions of the expanders clad the frame members and cover the fasteners for pleasing appearance. Moisture barriers separate the fasteners and the frame from the environment. A sill nose cover clads the sill.

Abstract: An operating mechanism for a slat shade assembly of the type mounted between a pair of glazing panels of a window. The mechanism includes a sash and a pair of glazing panels which are supported by the sash. A slat shade is operatively positioned in the space between the glazing panels. An operating mechanism is secured to the surface of the window sash frame and is located between the two glazing panels. The operating mechanism is operatively connected to a selected portion of the slat shade assembly for moving the slats of the slat shade assembly between two extreme positions. An opening is provided in one of the glazing panels in a position which is adjacent to the slat shade operating mechanism. A manual control member is mounted on the one glazing panel and passes through the opening in the one glazing panel. The manual control member is operatively interconnected to the operating mechanism so that the slat shade may be moved to a desired position by the manual control member.

Abstract: A horizontal pivot window construction. The window includes a window frame having a sill, a head, and a pair of upright jambs which interconnect the ends of the sill with the ends of the head. The window sash is mounted within the frame and the sash includes upper and lower rails and upright stiles which interconnect the opposite ends of the upper and lower rails. Means are provided for supporting the window sash within the window frame for movement of the sash between a closed and locked position and an open and unlocked position. The supporting means includes means for pivotally mounting the sash within the frame for movement about a substantially horizontal axis so as to make the normal exterior side of the window accessible from the interior of the room in which the window is located. The supporting means also includes a member for vertically moving the sash between an upper position and a lower position when the stiles and the jambs are substantially coextensive with each other.
