Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
184 words
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.
Claim 2
Independent Claim
184 words
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.
Claim 3
Dependent Claim
37 words
The method of claim 1 wherein the step of displacing at least one of said plugs comprises displacing the plug of a plastic projection on said first body part into the tubular portion of the same projection.
Claim 4
Dependent Claim
47 words
The method of claim 1 wherein the step of displacing at least one of said plugs comprises displacing the plug of a plastic projection on a body part other than said first body part into the tubular portion of a plastic projection on said first body part.
Claim 5
Dependent Claim
56 words
The method of claim 3 wherein the plug of said projection on said first body part is separated from the projection on which it is formed before the plug of said projection on a body part other than said first body part is displaced into the tubular portion of said projection on said first body part.
Claim 6
Dependent Claim
50 words
The method of claim 3 or 4 wherein the plug displaced into the tubular portion of said projection on the first body part is passed through a bore in said first body part in communication with the bore in the tubular portion of said projection on said first body part.
