of rigid structural material rather than the several distinct and separate pieces from which it was designed and made the obvious advantage in this design over others lies in the ease by which the screen display can be used since the apparatus does not consist of a number of pieces which must be disassembled and reassembled with each break down and set up fig2 is a design drawing which describes the wall floor and optional top panels of a typical folding convertible screen display based upon this invention a left wall 1 a center wall 3 and a right wall 2 as well as the floor 4 and the optional angled top sections 5 a 5 c and 5 b may be formed from a single contiguous piece of material 6 or of separated pieces from material 6 flexible joints 7 define the boundaries between adjacent walls 1 and 3 and 3 and 2 as well as between walls 1 3 and 2 and adjacent optional angled top sections 5 a 5 c and 5 b and further between walls 1 3 and 2 and the adjacent edges of floor 4 where they are flexibly joined together when assembled they also describe the folded edges of the apparatus when it is erected for use these flexible joints 7 and other flexible joints described herein serve further to facilitate bending when assembling folding and erecting the screen display and may be formed by scoring and folding along predetermined lines where the rigid structural material is corrugated paperboard and the flexible joints are permanently formed.
