Abstract
Abstract A structural assembly comprises a one-piece fastener for mounting on a protuberant work support, for instance, a hollow boss. The fastener is in the form of a U-shaped anchoring clip having at least one pair of opposed resilient leg portions and a bridging portion desirably formed with means for securing a workpiece thereto. The arrangement is such that free end portions of the legs may be resiliently spaced apart during assemblage of the boss and clip but upon urging their retractive separation, angular inwardly projecting tangs struck from the opposite legs, respectively, bite into the boss to grip it and hence effectively retain the parts in assembled relation. The tangs preferably are shaped to centralize the securing means with respect to the work support.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
167 words
A one-piece push-on type fastener formed from sheet material for securing a workpiece in assembled relation to a protuberant work support and comprising a substantially U-shaped clip received over the work support, the clip including at least one pair of resilient legs extending from an integral leg-spanning portion, the free ends of said legs being spring biased toward each other and spreadable apart by engagement with opposed portions of the protuberant work support, said legs respectively having an intermediate portion formed with a tang struck inwardly therefrom to project toward the leg-spanning portion for cooperative gripping engagement with said opposed portions of the work support, the gripping edge of at least one of said tangs being of transversely recessed V-notch shape, and said workspanning portion being formed with means for securing The workpiece thereto, the arrangement being such that relative withdrawal of the assembled clip and/or the workpiece from the work support urges the tangs toward a straighter toggle relationship and hence tighter gripping of the support.
Claim 2
Dependent Claim
167 words
A one-piece push-on type fastener formed from sheet material for securing a workpiece in assembled relation to a protuberant work support and comprising a substantially U-shaped clip received over the work support, the clip including at least one pair of resilient legs extending from an integral leg-spanning portion, the free ends of said legs being spring biased toward each other and spreadable apart by engagement with opposed portions of the protuberant work support, said legs respectively having an intermediate portion formed with a tang struck inwardly therefrom to project toward the leg-spanning portion for cooperative gripping engagement with said opposed portions of the work support, the gripping edge of at least one of said tangs being of transversely recessed V-notch shape, and said workspanning portion being formed with means for securing The workpiece thereto, the arrangement being such that relative withdrawal of the assembled clip and/or the workpiece from the work support urges the tangs toward a straighter toggle relationship and hence tighter gripping of the support.
Claim 3
Dependent Claim
167 words
A one-piece push-on type fastener formed from sheet material for securing a workpiece in assembled relation to a protuberant work support and comprising a substantially U-shaped clip received over the work support, the clip including at least one pair of resilient legs extending from an integral leg-spanning portion, the free ends of said legs being spring biased toward each other and spreadable apart by engagement with opposed portions of the protuberant work support, said legs respectively having an intermediate portion formed with a tang struck inwardly therefrom to project toward the leg-spanning portion for cooperative gripping engagement with said opposed portions of the work support, the gripping edge of at least one of said tangs being of transversely recessed V-notch shape, and said work-spanning portion being formed with means for securing The workpiece thereto, the arrangement being such that relative withdrawal of the assembled clip and/or the workpiece from the work support urges the tangs toward a straighter toggle relationship and hence tighter gripping of the support.
Claim 4
Dependent Claim
167 words
A one-piece push-on type fastener formed from sheet material for securing a workpiece in assembled relation to a protuberant work support and comprising a substantially U-shaped clip received over the work support, the clip including at least one pair of resilient legs extending from an integral leg-spanning portion, the free ends of said legs being spring biased toward each other and spreadable apart by engagement with opposed portions of the protuberant work support, said legs respectively having an intermediate portion formed with a tang struck inwardly therefrom to project toward the leg-spanning portion for cooperative gripping engagement with said opposed portions of the work support, the gripping edge of at least one of said tangs being of transversely recessed V-notch shape, and said work-spanning portion being formed with means for securing The workpiece thereto, the arrangement being such that relative withdrawal of the assembled clip and/or the workpiece from the work support urges the tangs toward a straighter toggle relationship and hence tighter gripping of the support.
Claim 5
Dependent Claim
61 words
A fastener as in claim 1 wherein each leg is of generally planar form and said tangs are correspondingly V-notched at their ends to provide straight, converging gripping edges extending transversely of the legs, the workpiece securing means is a circular thread engaging formation, and the apexes of the notched tangs are aligned with the center of said thread engaging formation.
