Abstract

A self-centering nock is provided for use in a well-balanced nock-arrow or nock-bolt assembly. The self-centering nock includes compliant projecting protrusions or compliant arms that are substantially rotationally symmetric about a cross section normal to a main axis of the self-centering nock. The compliant projecting protrusions or compliant arms may be received in bolts that have bores of differing internal dimensions.

Claims

1-15. -15. (canceled)

16. A self-centering nock for partial insertion into a bore of a bolt, the self-centering nock comprising:

an intermediate portion composed of a rigid polymer substrate, wherein a plurality of compliant projecting protrusions composed of an elastic or viscoelastic material are co-molded onto the intermediate portion;

a proximal end contiguous with the intermediate portion; and

a distal end contiguous with the intermediate portion, the distal end including an opening configured to receive the string of at least one of a bow and crossbow.

18. The self-centering nock of claim 16, wherein there are four compliant projecting protrusions co-molded onto the intermediate portion.

19. The self-centering nock of claim 16, wherein the plurality of compliant projecting protrusions comprise ribs.

20. The self-centering nock of claim 19, wherein the ribs are compressible.

21. The self-centering nock of claim 16, wherein the elastic or viscoelastic material comprises a polycarbonate, an elastomer, or a rubber.

17. The self-centering nock of claim herein an inner diameter of the bore ranges between 0.24 inches to 0.314 inches.

22. A bolt-nock assembly comprising:

a bolt; and

a nock;

wherein the bolt includes a bore, and wherein the bore comprises a plurality of compressible projecting protrusions formed on an inner surface of the bore, wherein the bore is configured to receive a portion of the neck, and wherein the nock includes an opening configured to receive a string of at least one of a bow and crossbow.
