Tensioned projection screen assembly

Abstract

A projection screen assembly is disclosed including a projection screen and a projection screen frame. The projection screen frame includes a plurality of projection screen frame modules that may be coupled together to provide a projection frame for projection screens of different sizes.

1 . A projection screen apparatus including
 a projection screen including a first sheet defining a perimeter of the projection screen, at least one second sheet coupled to the first sheet, and a bungee received in the at least one second sheet, and   a projection screen frame supporting the projection screen, the at least one bungee coupling the projection screen to the projection screen frame.   
     
     
         2 . The projection screen apparatus of  claim 1 , wherein the second sheet includes a tube receiving the bungee. 
     
     
         3 . The projection screen apparatus of  claim 1 , wherein the second sheet includes an aperture receiving a terminal end of the bungee. 
     
     
         4 . The projection screen apparatus of  claim 1 , wherein the second sheet decreases in stiffness from an outer end to an inner end. 
     
     
         5 . The projection screen apparatus of  claim 1 , wherein the bungee includes a pair of terminal ends received in the second sheet.
