Abstract
An extruded plastic frame window sash in which the frame has a closed hollow body cross section with a recess extending into the hollow body from the outer periphery of the frame. The individual frame members are held together around a window pane by a tensioned band disposed within the recess and engaging each of the frame members. The tension band extends about the entire sash frame and is joined together at its end to maintain the tension in the band holding the frame together. The walls of the recess reinforce the frame members to prevent deflection induced by the tensioned band.
Claims17
A frame for a generally planar article comprising:
- a plurality of extruded plastic frame members having mitered ends and arranged in end-to-end relationship to form a closed frame surrounding said planar article, said frame members having a substantially identical cross sectional shape forming a closed hollow body defined in part by an outer peripheral wall and a recess in said outer peripheral wall extending into said closed hollow body, said recess being formed by a pair of spaced intermediate walls connected to said outer peripheral wall and extending therefrom into said closed hollow body and terminating in a base wall connecting said intermediate walls to one another;
- and
- a tensioned band disposed in said recess firmly engaging said base walls of said frame members and extending around said frame for maintaining said frame members in said end-to-end relationship.
A window sash comprising:
- a window pane having a periphery;
- a frame surrounding said pane comprising a plurality of extruded plastic frame members having mitered ends and arranged in end-to-end relationship to form a closed frame surrounding said pane, said frame members having a substantially identical cross sectional shape forming a hollow body defined in part by an outer peripheral wall and a recess extending into said hollow body from said outer peripheral wall, said recess being formed by a pair of spaced intermediate walls connected to said outer peripheral wall and extending therefrom into said hollow body and terminating in a base wall connecting said intermediate walls to one another, and means projecting from said hollow body forming a groove open inwardly of said closed frame for receiving said periphery of said pane to mount said pane within said frame;
- and
- a tensioned band disposed in said recess firmly engaging said base walls of said frame members and extending around said frame for maintaining said frame members in said end-to-end relationship.
A window sash comprising:
- a generally planar window pane;
- a rectangular frame surrounding said pane comprising four elongated extruded plastic frame members having mitered ends cut forty five degree angles and arranged in end-to-end relationship to form said frame, said frame members having a substantially identical cross sectional shape forming a generally rectangular hollow body defined by an outer peripheral wall, a pair of spaced side walls and an inner wall, said outer peripheral wall having a recess extending therefrom into said hollow body, said recess being formed by a pair of spaced intermediate walls connected to said outer peripheral wall and projecting into said rectangular hollow body and terminating in a base wall connecting said intermediate walls to one another;
- said frame members further having means forming a groove open inwardly of said closed rectangular frame for receiving said periphery of said pane to mount said pane within said frame;
- and
- a tensioned band disposed in said recess firmly engaging the base walls of said recesses in said frame members and extending around said rectangular frame for maintaining said frame members in said end-to-end relationship.
