Elastomeric bumper securing press fit clip

Claim 2

For securing a rib-carrying strip to an apertured member, the member being of material at least as hard as the material of the strip, a one-piece resilient sheet metal clip having opposed legs joined in a rounded nose portion receivable in the aperture of said member, the legs in localities nearer their free ends having inwardly projecting spaced prongs substantially directed toward said nose portion and engageable with opposite sides of the rib, the large intermediate said ends and the nose portion being bowed outwardly, and at least one pair of outwardly projecting prongs formed on the outwardmost intermediate bowed portions and substantially directed away from said nose portion whereby, upon engagement of the bowed portions with opposite walls of said aperture, the inwardly projecting prongs are yieldably urged together to bite into and grippingly engage said rib and the outwardly projecting prongs become embedded for securement in said walls to resist separation of the strip and the member.

Claim 3

A clip for securing a strip formed with a longitudinally recessed rib to an apertured mounting member by press fit, the material of the member being at least as hard as that of the rib, the clip comprising a generally V-shaped blind fastener having divergent resilient legs, mid portions of the legs being bowed outwardly and being formed at opposite side edges, respectively, with outwardly projecting prongs disposed on the outwardmost portion of said bowed legs and substantially directed toward the free ends of said legs which, when unstressed, are spaced apart greater than opposed walls of the aperture to be engaged thereby, the free ends of the legs being receivable along opposite sides of the strip rib, respectively, and the legs each bearing at least one inwardly projecting prong substantially directed opposite to said outwardly projecting prongs for biting into the rib when forced to do so by cam action of the aperture walls on receiving said bowed mid portions and on penetrably receiving said outwardly projecting prongs.

Claim 4

A clip for securing a strip formed with a longitudinally recessed rib to an apertured mounting member by press fit, the material of the member being at least as hard as that of the rib, the clip comprising a generally V-shaped blind fastener having divergent resilient legs, mid portions of the legs being bowed outwardly and being formed at opposite side edges, respectively, with outwardly projecting prongs disposed on the outwardmost portion of said bowed legs and substantially directed toward the free ends of said legs which, when unstressed, are spaced apart greater than opposed walls of the aperture to be engaged thereby, the free ends of the legs being receivable along opposite sides of the strip rib, respectively, and the legs each bearing at least one inwardly projecting prong substantially directed opposite to said outwardly projecting prongs for biting into the rib when forced to do so by cam action of the aperture walls on receiving said bowed mid portions and on penetrably receiving said outwardly projecting prongs.

Claim 5

A clip as in claim 2 wherein the inwardly projecting prongs are respectively formed in opposed side edges and any separation of the strip from the member tends to effect further embedment of the prongs.
