Abstract
A rectangular window frame includes a pair of vertical jamb members rigidly connected by a head member and a sill member all formed from extrusions of rigid plastics material. Each jamb and head member includes an inner section which snap-fits laterally into an outer section, and each outer section has a cross-sectional profile corresponding to that of the sill member to provide the frame with rigid fusion-welded mitered corner joints and a sill member with a low profile. The inner sections of the jamb and head members define channels for slidably receiving window units including a pair of rectangular sash frames each formed from extrusions and including snap-fit extruded cap members. The sash frames also receive removable extruded glazing strips which retain glass window panels within the sash frames.
Claims15
A window assembly adapted for use in a vertical wall of a building, comprising a generally rectangular frame supporting a generally rectangular light transmitting window unit, said frame including a pair of elongated vertical jamb members connected by a horizontal head member and a horizontal sill member, each of said members being formed from an extrusion of rigid plastics material, each of said jamb and head members including an extruded outer section and an extruded inner section, each of said inner sections defining an inwardly facing recess for receiving said window unit, said sill member having an inclined wall portion sloping downwardly and outwardly from said window unit, said outer sections of said jamb and head members each including a corresponding inclined wall portion and having a cross-sectional profile generally the same as the cross-sectional profile of said sill member, said inner sections of said jamb and head members disposed between said window unit and the corresponding said inclined wall portions of said outer sections, means connecting each of said inner sections to the corresponding said outer section, and said outer sections of said jamb members having welded mitered corner joints with said sill member and said outer section of said head member to provide a rigid said frame.
A window assembly adapted for use in a vertical wall of a building, comprising a generally rectangular frame supporting a generally rectangular light transmitting window unit, said frame including a pair of elongated vertical jamb members connected by a horizontal head member and a horizontal sill member, each of said members being formed from an extrusion of rigid plastics material, each of said jamb and head members including an extruded outer section and an extruded inner section, said outer section of said jamb and head members each having an inner portion projecting towards the interior of the building and a substantially thinner outer portion projecting towards the exterior of the building, each of said inner sections defining an inwardly facing recess for receiving said window unit, said sill member having an inclined wall portion sloping downwardly and outwardly from said window unit, said outer portions of said outer sections of said jamb and head members each including a corresponding inclined wall portion and having a cross-sectional profile generally the same as the cross-sectional profile of said sill member, said inner sections of said jamb and head members disposed between said window unit and the corresponding said inclined wall portions of said outer sections, means connecting each of said inner sections to be corresponding said outer section, and said outer sections of said jamb members having welded mitered corner joints with said sill member and said outer section of said head member to provide a rigid said frame
A window assembly adapted for use in a vertical wall of a building, comprising a generally recgtangular frame supporting a generally rectangular light transmitting window unit, said frame including a pair of elongated vertical jamb members connected by a horizontal head member and a horizontal sill member, each of said members being formed from an extrusion of rigid plastics material, each of said jamb and head members including an extruded tubular outer section and an extruded tubular inner section, each of said inner sections of said jamb members cooperating with said outer sections of said jamb members to define a set of inwardly facing channel-like tracks adapted to receive slide members for supporting said window unit, said sill member having an inclined wall portion sloping downwardly and outwardly from said window unit, said outer sections of said jamb and head members each including a corresponding inclined wall portion and having a cross-sectional profile generally the same as the cross-sectional profile of the said sill member, said inner sections of said jamb and head members disposed between said window unit and the corresponding said inclined wall portions of said outer sections, means forming a continuous connection of each said inner section to the corresponding said outer section, and said outer sections of said jamb members having welded mitered corner joints with said sill member and said outer section of said head member to provide a rigid said frame.
