Abstract

A panel structure for use in blocking glass panes against the passage of heat and cold. In one form the structure comprises first and second rigid foam panel sections joined together by a flexible sheet. The ends of the panels are exposed underneath the sheet so that they may be trimmed to fit the glass pane. Releasable means is also provided for mounting the panel sections in blocking relationship to the glass pane.

In another embodiment one of the rigid foam panel sections is provided with a tapered edge so that the section will fit behind the lock on a double hung window. In a further embodiment of the invention a plurality of u-shaped channels are placed around the periphery of the rigid foam sections to form framework. Releasable means may then be secured to the framework to hold the panel structure in blocking relationship to the glass pane. A still further embodiment encompasses use of a frame of rigid foam insulation which framework is placed around the glass pane and the releasable mounting means is secured thereto.

Claims

1. A panel structure for blocking a glass pane, said panel structure comprising:

a rigid framework of thermally insulating material, said framework extending on all sides of said glass pane;

a plurality of panel sections each constructed of a rigid thermally insulating material adapted to substantially prevent the passage of light therethrough, said panel sections having adjacent edges and each presenting opposed substantially flat surfaces, the ends of said panel sections being exposed under said sheet whereby said sections may be trimmed to a desired size;

a flexible sheet coupled with both panel sections along two aligned flat surfaces to hingedly couple said sections together, the adjacent edges of said sections being exposed beneath said sheet whereby when said flat surfaces are aligned said edges are is abutting relationship, said sheet being foldable to provide a hinge axis about which said sections may be moved to a folded position; and

means for coupling said panel sections with said framework to thereby hold said sections in a pane blocking position.

2. The invention of claim 1, wherein said framework comprises a rigid foam insulating material.

3. The invention of claim 2, wherein said framework presents a lip extension projecting therefrom in overlapping relationship to said panel sections when the latter are in their pane blocking position.

4. The invention of claim 3, wherein is included a plurality of U-channel members disposed around the outer edges of said sections to form a framework encasing said sections, each of said channel members having resilient sides for grasping said sections and being removable from said sections.
