PROJECTION BACKWALL APPARATUS AND SYSTEM

摘要

A collapsible projection backwall system utilizes a short throw projector andacollapsible framework to create a display usable in a small amount of space.Theframework is specifically configured to support and appropriately position aflexiblescreen member so that distortion is avoided. This is particularly significantin situationswhere a relatively large screen is utilized, which creates the need tomaintain appropriatetension upon the flexible screen member. The framework is specificallyconfigured to beslightly canted when in its extended configuration to thereby introducenatural tensionforces which will cooperate with the screen fabric to maintain the necessaryconfigurationfor the screen. This canted configuration is achieved by configuring a set ofcorner hingeassemblies and any central hinged assemblies to maintain this natural cant. Bymaintaining the desired forces on the display screen fabric a more efficientand functionaldisplay screen is created.
