Abstract

Abstract A self-captivating retractable handle for a portable television receiver cabinet is molded from an integral piece of polypropylene homopolymer plastic having an enlarged portion at one end. The other end of the handle has a downwardly extending projection hinged at the end with a second hinge located a short distance from the end of the handle. The first hinge permits bending the projection upwardly to enable the passage of the projection and the end of the handle through a pair of spaced slots in the receiver cabinet, and the second hinge is used to bend the projection back to pass it through a corresponding slot in the handle where it is locked to captivate the handle in the receiver cabinet. The resiliency of the material out of which the handle is made causes the handle to lie flat when not in use.
