<p>IMPROVED ACCESS SHIELD FOR UNCOVERED REFRIGERATED UNITS Energy losses from market refrigerated display cases, which are normally open, can be dramatically reduced by the use of the shield assembly of the present invention. The shield assembly comprises a plurality of transparent and resilient panels, each panel being adjacent to at least one another and having an overlapping relationship with the adjacent panel. The panels are mounted in a rigid frame and allow access therethrough by stretching and bending one or more of the panels along the overlap. The plurality of panels are fitted in a specifically configured mounting means such that they are held in place across an aperture of the display case. Retaining means are disposed adjacent the other end of the panels to keep the shield assembly in proper position.</p> |
