  • Patent number: 6550521
    Abstract: A system for suspending a video projection screen includes the principles of physical independence, or a somewhat “floating system,” employing at least some thermal expansion matching, centroid expansion dimension splitting combined with front to back progressive dimensional freedom, as well as corner gussets and rear corner brackets which contribute to the overall independence of each element of the system. The system of support provide clearance space from the rear of the system and which progressively provides a final touching clearance at the projection end of the system which has the minimum spacing between adjacent acrylic members to provide a nearly seamless system. In one embodiment, an expanse of typical acrylic screen material which may be either case, such as a Fresnel, or lenticular-fresnel material, or extruded, such as a diffusion material, having a thermal expansion of about 34×10−6 inch/inch/° F.
