发明名称 INFLATABLE SCREEN WITH FULLY INTERNAL TENSION
摘要 An inflatable moving screen system includes an inflatable support structure. The inflatable support structure has at least two horizontal tubes and at least two vertical tubes that collectively form a rectangular frame. A skirt is coupled to one of the horizontal tubes and to both vertical tubes. An air inlet is also provided in the support structure, so that as air is received, it can fill the support structure tubes. A projection surface is disposed within the rectangular frame and is permanently coupled directly to one of the horizontal tubes, to both vertical tubes, and to the skirt. An internal tension mechanism is also included. The skirt may be part of the internal tension mechanism, which is configured to create fully internal tension to stretch the projection screen automatically, by inflation of the four inflatable tubes, and without using external or removable tension mechanisms.
