Abstract:
A lens cell half for use in a projection television lens assembly, comprising:a pair of hook members projecting from a first edge of said lens cell half, said hook members being spaced apart a distance from each other on said first edge, each of said hook members further comprising a rigid portion that is integral with and tangent to said lens cell half, an end of said rigid portion of said hook member being integrally connected to an inverted flexible portion oriented at an angle .theta. with respect to a plane parallel to said rigid portion;a pair of loop members adapted for receiving a pair of mating hook members, each of said loop members being integral with and projecting from said lens cell half, each of said loop members being proximate to a second edge of said lens cell half, said loop members being spaced apart from each other on said lens cell half, each of said loop members having a tab member integral with and extending from an interior surface of each of said loop members, said interior surface being distal to said lens cell half, said tab member having an exterior end protruding out of said loop member and an opposite interior end surface residing within said loop member; wherein said inverted flexible portion of each of said hook members terminates in an engaging surface inclined at an angle .beta. with respect to a plane that is substantially at a right angle to said rigid portion, and wherein said interior end surface of each of said tab members residing within said loop members is inclined at about the same angle .beta. with respect to a plane that is substantially at a right angle to said tab member.
