Abstract
Abstract A picture display device includes a plurality of generally rectangular frames hinged together, edge-to-edge in an endless series. The frames can be folded into an arrangement defining a compact pack from which a pair of frames project in an inverted-V display position. The assembly of frames is detachably mountable to a support device and in a manner in which manual rotational movement of the upwardly projecting pair of frames from the display position back toward the pack automatically raises another pair of frames to the display position.

Total Claims: 12
Claim 1
Independent Claim
213 words
A device for presenting a series of photographs or the like in endless sequence comprising: a plurality of generally flat, substantially rectangular panels hinged together, edge-to-edge in an endless sequence, said panels being hinged in a manner to enable all but two of the panels to be arranged in a pack of accordian-like configuration, said two remaining of said panels defining a self-supporting, V-shaped configuration and extending away from the pack in a display position; each of the panels having an inner edge, an outer edge and a pair of side edges, the inner edges of adjacent panels being hinged to each other and the outer edges of adjacent panels being hinged to each other, hinges connecting the adjacent inner edges being constructed and arranged to enable the panels to be hinged in one direction and the hinges connecting the outer edgess of adjacent panels being constructed and arranged to permit hinging in the opposite direction, and means for supporting the panels in a manner to enable said pair of panels to be pivoted toward an end of the pack and, in response thereto, to cause the leading pair of panels at the opposite end of the pack to be pivoted away from the pack and to be advanced to the display position.
Claim 2
Independent Claim
