Abstract

A lighted nock assembly is disclosed for use with an archery projectile. A cap fits within the tail end of the projectile shaft. The cap comprises a shoulder to bear against the projectile shaft, a recess terminating in a floor portion, and a face to bear against the shoulder of a nock. An LED/battery assembly fits within the recess of the cap abutting the floor portion. A nock fits over the LED/battery assembly and into the recess of the cap. Ready-to-fire, the LED/battery assembly comprises an activation gap between the LED lamp and the body of the battery assembly. A gap, greater than or equal to the activation gap, is left between the shoulder of the nock and the face of the cap. When fired, the bow string drives an internal surface of the nock into the front end of the LED/battery assembly and illuminates the LED lamp.

Claims

1. A lighted nock assembly for use with an arrow, for illumination when the arrow is fired with a bow string, the lighted nock assembly comprising:

a cap having a recess with a floor portion, wherein the cap is secured within a tail of the arrow,

an LED/battery assembly disposed within said recess of said cap, and

a nock, wherein at least a portion of said nock is configured to fit in frictional engagement within said arrow, and wherein said LED/battery assembly is activated by driving said nock against said LED/battery assembly thereby compressing said LED/battery assembly against said floor portion of said cap recess and causing illumination of an LED lamp within said LED/battery assembly.

2. The lighted nock assembly of claim 1, wherein said nock comprises a shoulder configured to bear against a tail end of the arrow.

3. The lighted nock assembly of claim 1, wherein said LED/battery assembly may be configured to comprise an activation gap.

4. The lighted nock assembly of claim 1, wherein the LED/battery assembly is removably disposed within the recess of the nock.

5. A projectile for archery having an LED/battery assembly that is activated when said projectile is fired with a bow string comprising:

a tubular shaft;

a cap secured within a tail end of said tubular shaft, wherein said cap has a recess and a floor portion;

an LED/battery assembly disposed within a recess in said cap;

a nock disposed within said tail end of said tubular shaft, said nock encompassing said LED/battery assembly within a recess formed within said nock; and

wherein said LED/battery assembly is activated by driving said nock against said LED/battery assembly thereby compressing said LED/battery assembly against said floor portion of said cap recess and causing illumination of an LED lamp within said LED/battery assembly.

6. The lighted nock assembly of claim 5, wherein said nock comprises a shoulder configured to bear against a tail end of the arrow.

7. The projectile of claim 5, wherein said LED/battery assembly may be configured to comprise an activation gap.

8. The lighted nock assembly of claim 5, wherein the LED/battery assembly is removably disposed within the recess of the nock.

9. A process for using a lighted nock assembly in association with an arrow, the process comprising the steps of:

(a) inserting a cap into the tail end of a tubular arrow shaft, wherein the cap is secured within the tail end of the arrow;

(b) inserting a deactivated LED/battery assembly into a recess within the cap, the tail end of the LED/battery assembly abutting a floor portion of the cap recess;

(c) inserting a nock over the LED/battery assembly and into the tail end of the tubular arrow shaft;

(d) establishing a firing gap greater than or equal to an activation gap of the LED/battery assembly;

(e) nocking the arrow onto a bow string; and

(f) drawing and releasing the bow string, driving the nock into the LED/battery assembly;

thereby closing the firing gap and activation gap, and illuminating an LED lamp associated with the LED/battery assembly.

10. A process for using a lighted nock assembly in association with an arrow, the process comprising the steps of:

(a) inserting a cap into the tail end of a tubular arrow shaft, wherein the cap has a recess with a floor portion;

(b) inserting a deactivated LED/battery assembly into a recess within the cap, the tail end of the LED/battery assembly abutting the floor portion of the cap recess;

(c) inserting a nock over the LED/battery assembly and into the tail end of the tubular arrow shaft;

(d) establishing a firing gap greater than or equal to an activation gap of the LED/battery assembly;

(e) nocking the arrow onto a bow string; and

(f) drawing and releasing the bow string, driving the nock into the LED/battery assembly, thereby closing the firing gap and activation gap, and illuminating an LED lamp associated with the LED/battery assembly.
