Patent ID: 7730678

Claim:
A glass compound comprising a plurality of outer glass panes, a spacer arranged proximate edges of the glass panes which maintains the panes at a predetermined spacing from each other, a panel disposed in the spacing between the panes, the panel having panel surfaces, a transverse peripheral rim surface between the panel surfaces and a thickness which is less than the spacing between the glass panes, the spacing being free of any member or members that together simultaneously contact opposing surfaces of the panes and the panel, the panel having a total surface area which roughly corresponds to but is less than a total surface area of the spacing parallel to the glass panes, the panel being dimensioned and configured so that the peripheral rim surface is spaced from and out of contact with the spacer between the outer glass panes, whereby the panel is loosely arranged between the glass panes and the spacer, and a resilient member disposed between the peripheral rim surface and the spacer and capable of engaging only the peripheral rim surface of the panel for keeping the peripheral rim surface spaced apart from the spacer, the resilient member extending over at least a portion of the length of the peripheral rim surface.
