Abstract
Abstract The within improvements are applicable for window construction kits of the type used for providing storm, screen, sun-block, and/or tinted window coverings wherein, as understood, an appropriate film, such as plastic or the like, is attached by a so-called spline about its peripheral edges within a supporting frame. Among other improvements, the disclosure contemplates an optimum T-shape in the spline which provides an attached, conveniently gripped flat surface to the spline to facilitate its film-stretching entrance into said frame, to more readily place the spline into and remove it from its attached connection to said frame, as well as contributing to an enhanced appearance in the window and providing a dust cover thereto. The within disclosure also contemplates an adhesive system to facilitate attachment of the frame to a variety of surfaces.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
184 words
Improvements for a frame attached about a window for holding a plastic sheet in a taut condition in covering relation over said window of the type employing mounting strip means in surrounding relation to said window consisting of spaced apart walls bounding a sheet-engaging channel therebetween and having a sheet-engaging member sized to be inserted into said channel incident to frictionally engaging said sheet against said walls, the improvements to said frame comprising a cooperating pair of interfitting projection and groove means for stretching said plastic sheet free of wrinkles during said insertion of said sheet-engaging member into said channel, said projection being centrally located in upstanding relation along said channel and said groove being formed in said sheet-engaging member in facing relation thereto, whereby the initial movement of said member into said channel frictionally engages said sheet against said walls thereof to provide a corresponding initially taut condition in said sheet and subsequent insertion movement thereof thereafter forces said projection into said groove with said sheet in an interposed position therebetween to cause the further stretching out of any wrinkles in said sheet.
Claim 2
Dependent Claim

Improvements for a frame attached about a window for holding a plastic sheet in a taut condition in covering relation over said window of the type employing mounting strip means in surrounding relation to said window consisting of spaced apart walls bounding a sheet-engaging channel therebetween and having a sheet-engaging member sized to be inserted into said channel incident to frictionally engaging said sheet against said walls, the improvements to said frame comprising a cooperating pair of interfitting projection and groove means for stretching said plastic sheet free of wrinkles during said insertion of said sheet-engaging member into said channel, said projection being centrally located in upstanding relation along said channel and said groove being formed in said sheet-engaging member in facing relation thereto, whereby the initial movement of said member into said channel frictionally engages said sheet against said walls thereof to provide a corresponding initially taut condition in said sheet and subsequent insertion movement thereof thereafter forces said projection into said groove with said sheet in an interposed position therebetween to cause the further stretching out of any wrinkles in said sheet.
Claim 3
Dependent Claim
61 words
An improved combination mounting frame and plastic sheet for attachment over a window as claimed in claim 1 wherein said groove is of an extent to provide bifurcated depending legs in said sheet-engaging member to contribute to slight inward movement of said legs towards each other during insertion movement of said member into said channel, to thereby facilitate said insertion movement.
Claim 4
Dependent Claim
76 words
An improved combination mounting frame and plastic sheet for attachment over a window as claimed in claim 2 wherein attached to said bifurcated depending legs of said sheet-engaging member is a transversely oriented leg sized to extend laterally on opposite sides of said walls of said channel, whereby said overhang of said leg laterally beyond said channel walls effectively masks the presence of said walls to thereby contribute to an enhanced appearance in said mounting frame.
Claim 5
Dependent Claim
45 words
An improved combination mounting frame and plastic sheet for attachment over a window as claimed in claim 3 wherein said spaced apart walls providing said sheet-engaging channel is transversely slotted at spaced intervals therealong to enable the placement thereof into a rolled, compact storage condition.
Claim 6
Dependent Claim
20 words
An improved combination mounting frame and plastic sheet as claimed in claim 4 wherein said plastic sheet is preferably vinyl.
Claim 7
Dependent Claim
36 words
An improved combination mounting frame and plastic sheet as claimed in claim 5 including an adhesive applied to said mounting strip means to correspondingly contribute to adhesive attachment thereof in said surrounding relation to said window.
