Abstract

An elongate frame member of uniform cross-section is provided for a combined door and window frame assembly. The said frame member is adapted to divide an outer perimeter frame into two areas, one to accommodate an opening window and the other to accommodate a sliding door in its closed position and comprises a rigid supporting portion, an elongate recess of L-shaped cross-section to receive one edge of the window and an elongate flange connected to the supporting portion and spaced therefrom by an intervening web, said flange being so positioned, in the assembled frame, that a part of the sliding door when closed can engage between the flange and the supporting portion to facilitate a draught proof seal.

Independent Claims | See all claims (11)

1. 1. An elongate extruded metal frame member comprising in cross-sectional view: a supporting portion of hollow box section, a first flange extending a first wall of the box section to define with a second wall an L-shaped recess, a web extending a third wall of the box section, a second flange connected to said web and extending in the same direction as and parallel to said first flange, a projection extending from said web in the same direction as said first and second flanges and having a recess facing said second flange for retaining draught excluding material, said first and second walls having projections extending over said second wall for retaining a glazing bead adjacent said second wall, said first wall having a pair of adjacent claws facing toward the L-shaped recess and defining between them a channel for retaining draught excluding material or a glazing gasket.
2. 8. A sliding door and window frame assembly comprising a sliding door frame, a frame for a fixed panel and hinged window, a hinged window frame, an outer perimeter frame having an inner track for said sliding door frame and an outer track for said fixed panel and hinged window frame, a dividing frame member extending vertically to divide said perimeter frame into a door area and window area, said dividing frame member having an L-shaped portion extending into said outer track and forming an edge of said fixed panel and hinged window frame, said dividing frame member having an inwardly extending flanged web extending into said inner track for defining an interlocking closure for said door frame, said door frame having on its inner vertical edge a continuous projection adapted in the closed door position to engage within said flanged web, the remainder of said fixed panel and hinged window frame being interlockingly engaged in said outer track of said perimeter frame with said window frame mounted to open outwardly therefrom; said inner track comprising a rail positioned centrally along the track on a lower member of said perimeter frame, said second track comprising a channel in said perimeter frame defined between a pair of parallel ridges, said remainder of said fixed panel and window frame engaging with a snap fit between the said ridges, said lower perimeter frame member being of hollow cross-section and provided with draining means; and said lower perimeter frame member being constructed of separate upper and lower interlocking parts, said upper part having a horizontal floor formed with said rail and with drainage holes, and said lower part sloping downwardly and outwardly over its full width, there being drainage outlets at an outside lower corner of the lower frame member, the lower part having external legs terminating on a horizontal plane, one said leg being adjacent the inner edge of the lower frame member, said lower part having an inner vertical flange portion formed with a pair of claws defining a recess for retaining draught-excluding material, said recess facing outwardly towards said inner track.
3. 9. In a sliding door and fixed panel assembly: a hollow lower frame member having interlockingly engaged upper and lower parts formed as extrusions, said upper part having a horizontal upper surface and a rail defining an inner track for a sliding door and projections in an outer track for interlockingly retaining a tread member or fixed panel frame, and having drainage holes under both tracks, said lower part having an upper surface sloping downwardly and outwardly over its width, drain outlets at the lower outer edge of the frame member, leg projections extending downwardly from said lower part and terminating in a horizontal plane, the frame member having an upwardly extending rear flange, said flange being formed with a pair of claws defining a recess for retaining draught excluding material, said recess facing outwardly towards said inner track, a fixed panel assembly interlockingly engaged in said outer track projections over a first part of the length of the lower frame member, a door slidingly engaged on said rail, and a tread plate interlockingly engaged in said outer track projections over a second part of the length of the lower frame member.
