Abstract
A plastic rivet is composed of a resilient material and has a drive pin and a body. Drive pin has a head and a shank. Distal end of shank has a pair of resilient legs, and proximal end of shank has a transverse hole forming deflectable walls. A first pair of protrusions project radially outwardly from the legs, and a second pair of protrusions project radially outwardly from the walls. Body has a head and elongated portion insertable into holes in members to be joined. The elongated portion is comprised of a pair of outwardly tapered longitudinal members projecting from the head and interconnected by an inwardly tapered nose. Shank of drive pin is insertable into a passage which extends through the head and elongated portion of the body. When drive pin is predriven into the body, the first pair of protrusions engages into slots in the passage, retaining the drive pin within the body. As drive pin is driven into the body, legs and walls deflect inwardly. When drive pin is fully driven into body, the first pair of protrusions engage with mating surfaces formed at the distal ends of the longitudinal members, the second pair of protrusion engage with the slots, and the shank of the dri…
