Abstract

An archery nock includes a nock assembly and a light source disposed within the nock assembly. The light source includes a first color element and a second color element. The second color element is a different color than the first color element. The light source is configured to flash the first and second color elements on and off.

Claims

1. An archery nock, comprising:

a nock assembly; and

a light source disposed within the nock assembly, the light source comprising a first color element and a second color element, the second color element being a different color than the first color element, the light source configured to flash the first and second color elements on and off.

2. The archery nock of claim 1, wherein the first color element is a red color element and the second color element is a green color element.

3. The archery nock of claim 1, wherein the light source comprises a light emitting diode (LED).

4. The archery nock of claim 1, wherein the light source comprises a red/green/blue (RGB) LED.

5. The archery nock of claim 1, wherein the light source is configured to sequentially advance to a next one of a plurality of different colors upon the application of a magnetic field to the nock assembly.

6. The archery nock of claim 1, wherein the nock assembly comprises a nock end slidably disposed partially within a nock housing;

and wherein an activation gap is defined between the nock end and the nock housing, the light source being powered on when the activation gap is closed and powered off when the activation gap is open.

7. A method of illuminating an archery nock assembly, the method comprising:

providing a light source comprising a first color element and a second color element, wherein the first color element and the second color element are different colors; and

flashing each of the first and second color elements.

8. The method of claim 7, further comprising sequentially advancing a color of the light source to a next one of a plurality of different colors upon the application of a magnetic field to the nock assembly.

9. The method of claim 7, further comprising powering the light source on by closing an activation gap defined between a nock end and a nock housing of the nock assembly;

and powering the light source off by opening the activation gap.

10. The method of claim 7, wherein the first color element is a red color element and the second color element is a green color element.

11. The method of claim 7, wherein the light source comprises an RGB LED.

12. The method of claim 7, wherein the light source comprises an LED.

13. An archery nock system, comprising:

a nock assembly; and

a light source disposed within the nock assembly, the light source comprising a plurality of differently-colored color elements, the light source configured to sequentially advance to a next one of a plurality of different color settings upon the application of a magnetic field to the nock assembly.

14. The archery nock system of claim 13, wherein the plurality of differently-colored color elements includes red and green color elements.

15. The archery nock system of claim 13, wherein the light source comprises an RGB LED.

16. The archery nock system of claim 13, wherein the light source comprises an LED.

17. The archery nock system of claim 13, wherein the light source comprises a flip-flop circuit component.

18. The archery nock system of claim 13, wherein the nock assembly comprises a nock end slidably disposed partially within a nock housing;

and wherein the nock end and nock housing each include complimentary indexing features to prevent relative rotation of the nock end with respect to the housing as the nock end slides longitudinally within the nock housing.

19. The archery nock system of claim 13, wherein one of the plurality of different color settings is an LED off setting.

20. The archery nock system of claim 13, wherein the nock assembly comprises a nock end slidably disposed partially within a nock housing;

and wherein an activation gap is defined between the nock end and the nock housing, the light source being powered on when the activation gap is closed and powered off when the activation gap is open.
