Display Device

Abstract

A display device comprising a plurality of parallelepipeds ( 4 ) arranged in a stack, each parallelepiped having a resilient means ( 11 ) for urging it from a closed position, in which it lies generally flat, to a fully opened position, the structure being foldable from a first position as which the stack of parallelepipeds are fully open to a second position at which they are fully loaded.

1 . A display device comprising a plurality of parallelepipeds arranged in a stack, each parallelepiped having a resilient means for urging it from a closed position, in which it lies generally flat, to a fully opened position, the structure being foldable from a first position at which the stack of parallelepipeds are fully open to a second position at which they are fully folded. 
   
   
       2 . A device as claimed in  claim 1 , including a foldable sheet which is connected to a face of the stack such that in the first position the sheet is substantially planar and in the second position the sheet is flattened concertina fashion, the sheet bearing a desired image, such as an advertising image, on its main face. 
   
   
       3 . A device as claimed in  claim 2 , wherein the foldable sheet is hingably attached to a base upon which the stack lies. 
   
   
       4 . A device a claimed in  claim 1 , including one or more members, which bear at least part of the resilient means, and define the fully opened position. 
   
   
       5 . A device as claimed in  claim 4 , wherein the members comprise one or more diagonally disposed members fixed to a junction between one adjacent pair of panels of the parallelepiped and adapted to impinge towards the diametrically opposite junction when the parallelepiped is fully opened. 
   
   
       6 . A device as claimed in  claim 4 , wherein the members comprise one or more layers of diagonally disposed members, the ends of pairs of which members are brought towards each under the action of resilient means. 
   
   
       7 . A device as claimed in  claim 6 , wherein each diagonal layer includes a longitudinal slot in which slides a tongue part of a respective second diagonal layer which slides relative to the first layer.
