ABSTRACT:
A sprocket assembly for a louver arch assembly for semi-circular, non-perfect or imperfect arch frame assemblies with louvers rotably mounted therein. A tensioning mechanism keeps the louvers taut between an arched frame member and a smaller anchorage frame member. An actuating mechanism is used to rotate the louvers upon the application of a predetermined force to a chain that coacts with the sprocket assemblies coupled with hooked clip members that removably hold the louvers. The sprocket assembly includes a through opening and a socket with cooperative dimensions to receive the headed end of a pin, and an internal inwardly extending pin. A longitudinal channel is cooperatively disposed to receive the inwardly extending pin therein. In this manner, the louvers are rotated between two extreme positions.
