Extruded plastic panel holding and jointing strips and window assemblies therewith

DETAILED DESCRIPTION In my invention, I have provided practical and improved extruded plastic panel framing, holding and joining strips suitable for use with glazing panels of various thickness and adaptable to many different types of existing prime windows.
The strips are strong, durable and easily adapted to receive decorative lamination or coloring during manufacture.
The strip is also suitable for use as a mounting for exterior, as well as interior, window application, and is strong enough to receive conventional glass, as well as plastic, glazing panels.
In my invention extruded lengths of rigid material are joined by an intrinsic hinge element and a communicating set of releasably interlocking legs or ribs.
The rigid elements form a channel which receives the edges of the glazing material to be held; and the inner surfaces of the channel include protruding gasket ribs which adapt the channel to receive glazing panes of a range of thicknesses and hold and provide an air seal for the pane.
As well as being useful for interior and exterior use, the strips may be installed to the casing of a prime window with a variety of means and may also be adapted to be installed on the interior casing of a window as well as around the frame or other plane surface surrounding a prime window.
Thus, my invention provides a universal strip for window mounting.
More particularly, the invention is described by reference to the drawings and following description of the preferred embodiment.
