International Classification:

A47H 100

US Classification:

Abstract:

A prefabricated window system includes a rectangular main frame having a top frame portion, a bottom frame portion, and two side frame portions. The frame portions are extruded thermoplastic elements having substantially the same cross-sectional configuration. The frame portions include first and second channels which, in the side frame portions, serve to guide windows. The frame portions also provide a third channel which, in the side frame portions, serve to guide a screen member. The window system also includes a sill which is connected to the bottom frame portion. The sill includes an extruded thermoplastic element which is snap-connected to the bottom frame portion and which is braced with respect to the bottom frame portion. The sill covers the window channels of the bottom frame portion, and additionally has an overhang portion which covers the screen channel of the bottom frame element to keep debris out. The sill also has a trough for receiving the bottom edge of one of the windows when it is closed, and a seal which is directed toward the trough to limit air incursion.

US Classification:

Abstract:

A prefabricated window system includes a main frame which is fabricated from thermoplastic elements having substantially the same cross-sectional configuration. Windows and a screen are slideably mounted in the main frame. A thermoplastic sill is snap-connected to the bottom portion of the frame and a decorative cover is snap-connected to the top portion. Stop elements, having the same cross-sectional configuration as the cover element, are snap-connected to the side portions of the frame in order to prevent the windows from being raised or lowered too far. The windows can be pivoted for cleaning, and the frame includes portions which overlap the outer peripheries of the windows to prevent them from inadvertently being rotated outward. These portions also reduce air incursion. A latch is mounted on one window and a keeper which cooperates with the latch is mounted on the other, the keeper being firmly mounted in the window sill by upwardly extending screws.
