Abstract
Abstract A resilient connector suitable for use on sheet metal which comprises an integral resilient plastic molding having a lower tubular section and a pair of flanges at its top extremity. The edges of an opening in sheet metal are grasped between the flanges. Preferably a grid is molded integrally with the top end of the device, and assumes a position substantially flush with the sheet metal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
128 words
A resilient connector comprising a tubular member of substantially uniform internal cross-sectional area, a first annular end flange projecting outwardly at one end of said tubular member, a second annular flange disposed on said tubular member immediately axially below said end flange and defining therewith a groove adapted to receive sheet material, said end flange being of greater diameter than said second flange and having its outer extremity tapering to a featheredge which, when unrestrained, depends axially toward said second flange below the innermost axial edge of said groove defined by said second flange, whereby said connector may be snapped in place with sheet material received in said groove and pressed by said second flange into flush fluid tight engagement against the underside of said first end flange.
Claim 2
Dependent Claim
128 words
A resilient connector comprising a tubular member of substantially uniform internal cross-sectional area, a first annular end flange projecting outwardly at one end of said tubular member, a second annular flange disposed on said tubular member immediately axially below said end flange and defining therewith a groove adapted to receive sheet material, said end flange being of greater diameter than said second flange and having its outer extremity tapering to a featheredge which, when unrestrained, depends axially toward said second flange below the innermost axial edge of said groove defined by said second flange, whereby said connector may be snapped in place with sheet material received in said groove and pressed by said second flange into flush fluid tight engagement against the underside of said first end flange.
Claim 3
Dependent Claim
128 words
A resilient connector comprising a tubular member of substantially uniform internal cross-sectional area, a first annular end flange projecting outwardly at one end of said tubular member, a second annular flange disposed on said tubular member immediately axially below said end flange and defining therewith a groove adapted to receive sheet material, said end flange being of greater diameter than said second flange and having its outer extremity tapering to a featheredge which, when unrestrained, depends axially toward said second flange below the innermost axial edge of said groove defined by said second flange, whereby said connector may be snapped in place with sheet material received in said groove and pressed by said second flange into flush fluid tight engagement against the underside of said first end flange.
Claim 4
Dependent Claim
128 words
A resilient connector comprising a tubular member of substantially uniform internal cross-sectional area, a first annular end flange projecting outwardly at one end of said tubular member, a second annular flange disposed on said tubular member immediately axially below said end flange and defining therewith a groove adapted to receive sheet material, said end flange being of greater diameter than said second flange and having its outer extremity tapering to a featheredge which, when unrestrained, depends axially toward said second flange below the innermost axial edge of said groove defined by said second flange, whereby said connector may be snapped in place with sheet material received in said groove and pressed by said second flange into flush fluid tight engagement against the underside of said first end flange.
Claim 5
Dependent Claim
32 words
A connector as defined in claim 1, said connector being an integral unitary molding of resilient plastic material and including a grid integrally molded with said one end of said tubular member.
