Abstract
Abstract A display device has a window having a frame and a window opening and a rear panel spaced from the window. A slide is adapted to slide between the window and the rear panel from a window open to a window closed position and has a slot adjacent one end thereof. An endless flexible band passes through the slot and the slide and around the other end of the slide. The band is secured to a portion of the window frame which is adjacent the slot when the slide is in the window closed position. The band carries a display underlying the window opening when the slide is in the window closed position and moving behind the slide when the slide is moved to the window open position. The inside of the rear panel carries a display underlying the window opening and visible through the window opening when the slide is in the window open position.

Claim 1
Independent Claim
223 words
A display device comprising: a planar frame having opposed upper and lower edges, opposed side edges and a window opening, an endless flexible band having substantially parallel edges, said flexible band being secured to the frame between the window opening and one side edge of the frame on a line substantially normal to the edges of the band, lying behind and overlapping the window opening, and having a display opposite the window opening for viewing through the window opening, a planar slide means having a pair of opposed edges substantially normal to the edges of the band, said band substantially encompassing the slide means between the opposed edges thereof, a handle integral with the slide means extending beyond said one side edge of the frame for manually moving the slide means in the direction away from the other side edge of the frame to rotate the band about the slide means and move the band away from the window opening and for subsequently returning the slide means to its original position, a planar panel behind the slide means and connected to the frame, said panel presenting a display underlying the window opening and visible when the band is moved away from the window opening, whereby reciprocal movement of the handle and the associated slide means results in the presentation of the displays alternatively.
