Abstract: A method and apparatus for producing thermoplastic frames for fenestration in which extruded frame members are cut to length, heated to a selected temperature uniformly throughout their cross section to soften the material and while heated, profiling selected portions of the cut members, driving a fastening clip with a hole therein into one of the cut members, and drilling holes in portions of the cut members in locations for coaxial alignment in assembly of the cut members, a hole in the fastening means plate coaxial with one of the drilled holes, and placing the members in selected angular assembled relation and inserting and threading a securement member into the aligned holes of the cut members and the fastening plate for retaining the frame members in assembled angular relation.

Abstract: A sliding door construction in which two sliding door panels are adapted to be moved into open position or into a position where one panel is in open or partially open position and the other panel is in closed position and wherein one of the juxtaposed stile members of the door panels is provided with a movable pivoted insect barrier blade extending the length of the stile member and in operative insect barrier position lying normal to the plane of the door panels and having a width for virtually closing the space between the stile and the surface of the other door panel. In non-operative position of the barrier blade, the blade lies parallel to the plane of the door panels. The barrier blade has an actuator rib engageable by an actuator flange carried by the stile of the other door panel for pivotally moving the blade into the said normal position to the planes of the door panels and to parallel position of the door panels.

Abstract: A quickly releasable and attachable latch bracket for latch means provided in vehicle sunroof constructions adapted to be completely removed from a sunroof opening in a vehicle wall. In removal of a sunroof from the opening, the latching mechanism remains connected to latch brackets and the latch brackets are provided a construction for quick release thereof from the frame member defining the sunroof opening whereby the periphery of the opening is unobstructed by any sunroof hardware. A latch bracket means having a construction for engagement with cooperable slots and recesses on a frame member and releasable retainer pins carried on pivotally mounted release levers wherein the retainer pins are unstressed by sunroof loads. A method for quickly releasing such a latch bracket from a frame member in a sunroof construction.
