Abstract

A nock or an arrow having a nock with a chemical light source allows an archer or hunter to more easily locate and retrieve an arrow that has been shot from a bow. The nock is inserted into an arrow, wherein the nock comprises a body having an end for receiving a bowstring and an insert projecting from an opposing end. The body is formed of a translucent material for transmitting the light so that the light is visible to a user or others. The nock has a recess formed in the insert and the body. A chemiluminescent lightstick is utilized as the light source, and the insert is inserted into an end of the arrow.

Claims

1. A nock inserted into an arrow comprising:

a body having an end for receiving a bowstring and an insert projecting from an opposing end, the body formed of a translucent material;

a chamber formed in the insert and the body, the chamber having a first compartment and an adjacent second compartment, the compartments housing different chemicals, the chamber having means for rupturing the second compartment and mixing the chemicals of the first compartment with the chemicals of the second compartment for generating chemiluminescent light;

rupturing means having a head and a point at an end opposite the head, the head exposed within the notch, rupturing means urged toward and rupturing the second compartment in response to force applied to the head by placement of the bowstring within the notch; and

the insert inserted into an end of the arrow.

2. The nook of claim 1, wherein the body having an end for receiving the bowstring comprises a notch formed by a pair of legs separated by a distance sufficient to receive the diameter of the bowstring.

3. The nock of claim 1, wherein the insert has a diameter smaller than the body, the diameter of the insert offset so as to align the exterior of the body substantially coplanar to the exterior of the arrow.

4. The nock of claim 1, wherein the nock is removable from the arrow and replaceable by another nock.

5. The arrow of claim 4, wherein the notch is formed by a pair of legs separated by a distance sufficient to receive the diameter of the bowstring.

6. The arrow of claim 4, wherein the nock is disposable.

7. An arrow having a light source comprising:

an arrow body having a sharp point and fletching;

a nock having a notch at an end for receiving a bowstring and an insert at an opposing end, the insert inserted into an end of the arrow body, the nock formed of a translucent material;

the nock having a chamber, the chamber having a first compartment and an adjacent second compartment, the compartments housing different chemicals, the chamber having means for rupturing the second compartment and mixing the chemicals of the first compartment with the chemicals of the second compartment for generating chemiluminescent light; and

rupturing means having a head and a point at an end opposite the head, the head exposed within the notch, rupturing means urged toward and rupturing the second compartment in response to force applied to the head by placement of the bowstring within the notch.
