Three dimensional publicity body made from unitary blank - has pair of movable wings folding along bending lines under action of tensioning cord

摘要

The method is for making up a three dimensional body for publicity purposes from a blank. The sheet has a fixed part (12) and two movable parts (18,20) which fold along bending lines (22,24). The folding parts are formed by tabs (26,28;34,36), themselves bent along a line (30,38) parallel to the others. A single flexible, tensioned cord is fixed by its ends to a point (50) on the fixed part (12), near the bending line (22) of one swivelling part and a second point (44) on the other tab (36) of the second swivelling part (20). The cord tension controls the erection of the assembly.
