Abstract

An archery arrow having an improved bowstring-receiving slot. The slot defines a generally nonlinear bowstring-receiving groove to establish limited frictional engagement between the slot defining walls and the bowstring, whereby the arrow is frictionally supported on the bowstring until released when shot from the bow. The slot may be in the shape of an arc of a circle, a '"'"''"'"''"'"''"'"'V'"'"''"'"''"'"''"'"' or a chevron.

Claims

1. In an arrow including a shaft and a nock, said nock having spaced walls forming an open-ended bowstring-receiving transverse slot in said nock, the improvement wherein said spaced walls of said nock bounding said slot execute a nonlinear course across said nock to establish a bowstringreceiving zone in said nock, opposed said walls including integrally formed projection means directed inwardly into said zone, said projection means being arranged as an alternating array along opposed said side walls to define spaced points of physical abutment between said walls and a bowstring extending through said slot and establishing an inflected line of physical segments in that portion of the bowstring passing through said slot. whereby, upon engagement of said arrow on said bowstring with said bowstring passing through said slot, said projection means on said walls of said nock frictionally stressingly engage said bowstring and establish therein forces tending to effect therein a distortion from a normally straight line path, thereby releasably to support said arrow nock on the bowstring and to preclude inadvertent disengagement of said arrow nock from said bowstring prior to release of the arrow when the arrow is shot from the bow.

2. The improvement as set forth in claim 1 wherein said walls bounding said slot in said nock define an arcuately curved bowstring-receiving groove as viewed endwise of the arrow and in a plane extending transversely of the arrow shaft.

3. The improvement as set forth in claim 1 wherein said walls bounding said slot in said nock define a generally V-shaped groove in said nock, as viewed endwise of the arrow and in a plane extending generally transversely of the arrow shaft.

4. The improvement as set forth in claim 1 wherein one of opposed said walls includes at least two projection means operable to engage at linearly spaced positions a bowstring seated in said slot, and wherein the other of said walls includes projection means operable to engage said bowstring at a point intermediate said linearly spaced positions.
