Abstract

A rivet fastener assembly is configured to securely clamp together one or more components. The rivet fastener assembly includes a pin and a rivet body having a collar and a column extending from the collar. The rivet body further includes a collar stop configured to provide a positive locating feature for the pin once assembled.

First claim

We claim:

1 . A rivet fastener assembly configured to securely clamp together one or more components, the rivet fastener assembly comprising:
a pin; and a rivet body including a collar, a column extending from the collar, and a collar stop, wherein the collar stop is configured to provide a positive locating feature for the pin, once assembled.

2 . The rivet fastener assembly of claim 1 , wherein a passage is defined through the collar and the column, wherein the column comprises:
a first set of legs configured to fold and directly contact the one or more components when folded; and a second set of legs configured to fold and reinforce the first set of legs when folded.

3 . The rivet fastener assembly of claim 1 , wherein the pin includes a ledge configured to engage the collar stop.

4 . The rivet fastener assembly of claim 2 , wherein the first set of legs and the second set of legs comprise bulges that project radially outward and inner recessed areas.

5 . The rivet fastener assembly of claim 2 , wherein the pin comprises a plurality of annular projections and a beveled nose.

6 . The rivet fastener assembly of claim 5 , wherein the pin comprises a protrusion that is proximate to a first distal end of the pin, and between the annular projections and the beveled nose.

7 . The rivet fastener assembly of claim 6 , wherein the protrusion is configured to pre-flex at least one leg of the first set of legs or the second set of legs.

8 . The rivet fastener assembly of claim 5 , wherein the rivet body further comprises a plurality of grooves configured to interlock with the annular projections.

9 . The rivet fastener assembly of claim 8 , wherein the grooves are proximate to the collar stop.

10 . A rivet fastener assembly configured to securely clamp together one or more components, the rivet fastener assembly comprising:
a pin; and a rivet body including a collar having an opening and a column extending from the collar and having an interior channel, wherein the opening is contiguous with the interior channel, and wherein a diameter of the opening is smaller than a diameter of the interior channel.

11 . The rivet fastener assembly of claim 10 , wherein the column further includes:
a first set of legs having radial gaps therebetween; and a second set of legs having radial gaps therebetween.

12 . The rivet fastener assembly of claim 11 , wherein the first set of legs and the second set of legs comprise radially outward extending bulges and inner recessed areas.

13 . The rivet fastener assembly of claim 12 , wherein the pin includes a longitudinal shaft, a ledge, and a plurality of circumferential rings extending from the ledge.

14 . The rivet fastener assembly of claim 13 , wherein the longitudinal shaft has a first diameter, and the ledge has a second diameter that is different from the first diameter.

15 . The rivet fastener assembly of claim 14 , wherein the pin further includes a beveled nose with a lower edge having a third diameter, and wherein the third diameter is different from the first diameter and the second diameter.

16 . The rivet fastener assembly of claim 15 , wherein the pin further comprises a convex ring that circumscribes a first edge of the plurality of circumferential rings.

17 . The rivet fastener assembly of claim 16 , wherein the convex ring is proximate to the second set of legs.

18 . A rivet fastener assembly, the rivet fastener assembly comprising:
a pin having a longitudinal shaft, a securing section, a bulbous head; and a rivet body having a column and a collar with a first opening therethrough, wherein the column comprises:
component-engaging legs;
reinforcing legs;
an internal passage that extends between the first opening and a second opening; and
a locking section proximate to the first opening,
wherein the first opening has a diameter smaller than a diameter of the securing section.

19 . The rivet fastener assembly of claim 18 , wherein a diameter of the bulbous head is larger than a diameter of the second opening.

20 . The rivet fastener assembly of claim 18 , wherein the rivet body further includes an annular wall, the annular wall defining the first opening.
