ABSTRACT:
An anchor base for integral plastic structures includes an articulated series of lever arms joined together in at least one joint by means of a living hinge in order to establish a preferred point of articulation. The leverage is such that, as a first pair of the lever arms are squeezed together to insert them into a mounting hole in a chassis, a second pair of lever arms, for giving lateral support, are initially pulled down. As the anchor base penetrates the mounting hole, the entire lever system pivots while lateral support levers are pushed up to spread the first pair of arms. Shoulders on the first pair of arms are forced under the lower side of the chassis, in order to capture the anchor base and to resist its removal. If the first pair of arms are thereafter squeezed together below the underside of the chassis, it is easy to remove the anchor base.
