Abstract
A method and structure for assembling plastic parts is disclosed wherein a first part is formed with integral projections and each including a tubular shank and a plug attached to the shank by a frangible web. A second part having apertures therein which mate with the projections is secured to the first part by displacing the plugs into the shanks which are thereby caused to expand.
Claims5
A method of securing mating parts together, comprising:
- forming a plurality of body parts with a plurality of integral plastic projections thereon, each projection extending along an axis and including a tubular portion having a tapered bore therein whose cross section decreases with distance away from the body part, a plug having a cross section perpendicular to the axis larger than the cross section of at least a portion of the bore, and a frangible web axially connecting said plug to the end of said tubular portion remote from the body;
- forming a plurality of cover parts with a plurality of apertures therethrough adapted to mate with the plurality of projections on said plurality of body parts;
- positioning a first one each of said body and cover parts together in a mating relationship;
- and
- displacing at least one of said plugs so that its connecting web is ruptured and the plug is urged into the bore in the tubular portion of a plastic projection of said first body part, thereby causing said tubular portion to expand and secure said projection in the mating aperture.
