Lockable arrow nock
First Claim
1. An arrow nock for attachment to a tubular end of an arrow shaft as part of an arrow, said tubular end having interior side walls defining an open receiving cavity of the arrow shaft, said arrow nock comprising:
- an arrow nock body including an insert end portion and an opposing nock end portion,said insert end portion including exterior side walls and being configured and dimensioned for telescopic insertion into the open receiving cavity of the arrow shaft in an axial direction with respect to the arrow shaft,said nock end portion including a receiving slot configured for receiving a bowstring therein; and
locking means for locking the arrow nock body to the arrow shaft, including means engageable with the nock body for selectively moving the exterior side walls of the insert end portion radially outward into contact with the interior side walls of the arrow shaft such that said insert end portion is held in frictional engagement with said interior side walls to thereby lock said insert end portion to the arrow shaft.

Abstract
A nock that mounts to an arrow shaft. The nock is designed of a light weight plastic material. It incorporates the use of a mechanical locking mechanism to secure it to the end of an arrow shaft. The portion of the nock that is inserted into the arrow shaft, or the insert end of the nock, is expanded by a small set screw located inside a cavity in the insert end of the nock. This expansion of the nock presses against the inside walls of the arrow consequently locking the nock in place. The nock is designed to mount securely to the arrow shaft without the use of adhesives or glue.

9. A method for fabricating an arrow nock for attachment to a tubular end of an arrow shaft as part of an arrow, said tubular end having interior side walls defining an open receiving cavity of the arrow shaft, said method comprising the steps of:
-
(a) forming an arrow nock body including an insert end portion and an opposing nock end portion, such that said insert end portion includes exterior side walls and is configured and dimensioned for telescopic insertion into the open receiving cavity of the arrow shaft, and such that said nock end portion includes a receiving slot configured for receiving a bowstring therein; and (b) forming locking means for locking the arrow nock body to the arrow shaft, including means engagable with the nock body for selectively moving the exterior side walls of the insert end portion radially outward into contact with the interior side walls of the arrow shaft such that said insert end portion is held in frictional engagement with said interior side walls to thereby lock said insert end portion to the arrow shaft. - View Dependent Claims (10)

11. An arrow comprising:
-
an elongate arrow shaft having a hollow tubular end, said tubular end including interior side walls defining an open receiving cavity; an arrow nock body including an insert end portion and an opposing nock end portion, said insert end portion including exterior side walls and being configured and dimensioned for telescopic insertion into the open receiving cavity of the arrow shaft in an axial direction with respect to the arrow shaft, said nock end portion including a receiving slot configured for receiving a bowstring therein; and locking means for locking the arrow nock body to the arrow shaft, including means engageable with the nock body for selectively moving the exterior side walls of the insert end portion radially outward into contact with the interior side walls of the arrow shaft such that said insert end portion is held in frictional engagement with said interior side walls to thereby lock said insert end portion to the arrow shaft.
