ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to window sashes and frames and, more particularly, to double-hung window sashes and frames therefor, which are constructed from (1) extruded parts that are composed of a plastic such as vinyl, and (2) milled or otherwise shaped parts that are composed of another material such as wood.
2. The Prior Art
A need has developed for window sash and frame assemblages that combine the advantages of (1) extruded construction components having the durability of a plastic material such as vinyl, and (2) milled or otherwise-shaped construction components having the esthetics of another material such as wood or an equivalent. It is desired that such assemblages be adapted for either new construction wherein ease of installation is an advantage, or old construction wherein out-of-plumb openings are common.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a sash and frame assemblage for a window that is characterized by: (1) extruded plastic parts that feature a few interactive primary cross-sectional profiles, and (2) milled wood or otherwise-shaped parts that feature a secondary cross-sectional profile. The primary and secondary profiles coact simply, securely and attractively. The primary and secondary profiles, in cross-section, interactively feature a unique extrusion from which an entire sash is constructed, and a unique milled or otherwise-shaped facing which snaps precisely into secure engagement with such a sash. In addition to this unique extrusion, only a few auxiliary extrusions are needed. These auxiliary extrusions are specifically required for the forward and rearward meeting rails, and for out-of-plumb compensation. The frame of the present invention features extruded jambs that are pressed against the stiles of the window sashes by a resilient backing.
Other objects of the present invention will in part be obvious and will in part appear hereinafter.
