Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
100 words
A transparent insulating building panel reversibly mounted for positioning commensurate with the outside temperature, comprising: a frame pivotally mounted in the plane of a wall of said building, a pane of tinted heat Absorbing glass mounted within said frame, a pair of spaced apart glass panes mounted within said frame and in air tight engagement therewith, said pair of panes mounted in spaced relation and parallel to said pane of heat absorbing glass, and aperture means in said frame providing an unrestricted path of air flow through the space between the heat absorbing glass and the said pair of panes.
Claim 2
Dependent Claim
100 words
A transparent insulating building panel reversibly mounted for positioning commensurate with the outside temperature, comprising: a frame pivotally mounted in the plane of a wall of said building, a pane of tinted heat Absorbing glass mounted within said frame, a pair of spaced apart glass panes mounted within said frame and in air tight engagement therewith, said pair of panes mounted in spaced relation and parallel to said pane of heat absorbing glass, and aperture means in said frame providing an unrestricted path of air flow through the space between the heat absorbing glass and the said pair of panes.
Claim 3
Dependent Claim
26 words
The combination of claim 1 and further including at least a partially reflective surface coating on the exterior surface of the pane of heat absorbing glass.
Claim 4
Dependent Claim
42 words
The combination of claim 1 and further including air duct means disposed to communicate with at least some of the aperture means when the said panel is positioned so that the heat absorbing glass is juxtaposed to the interior of the building.
