Abstract

This invention relates generally to a nock assembly that is illuminated and more particularly to a nock assembly that has a power source that is removable from the nock assembly for use with an electrically conductive arrow shaft having a nock, illumination member, conductor, and a power source. The illumination member and conductor are in electrical communication with the power source. The power source is in removable engagement with the nock. The principle use is for archers however other applications will benefit from this invention. For example, emergency locators and outdoor lighting displays will benefit from this invention.

Claims

1. A nock assembly for use with an arrow, comprising:

a nock having a first nock portion, a second nock portion, and a step surface located between said first nock portion and said second nock portion, said first nock portion having a first end, a nock bore defined by a first curvilinear surface and a longitudinal axis, and at least one aperture disposed in said first nock portion generally adjacent to said step surface and opening into said nock bore;

a power source having a case generally engaging said first nock portion and a terminal, and said power source being in generally removable engagement with said nock;

an illumination member having a pair of leads, said illumination member being disposed in said nock bore, and one of said pair of leads extending through one of said at least one aperture and another of said pair of leads being in electrical communication with said terminal of said power source; and

a conductor being in electrical communication with said case and extending from said nock bore to an outer surface of said nock.

2. The nock assembly for use with an arrow, as set forth in claim 1, wherein said case having a groove generally disposed about said case, said groove having a resilient member disposed therein, and said resilient member generally engaging said nock bore.

3. The nock assembly for use with an arrow, as set forth in claim 2, wherein said resilient member being an o-ring.

4. The nock assembly for use with an arrow, as set forth in claim 2, wherein said groove defines a shoulder portion.

5. The nock assembly for use with an arrow, as set forth in claim 4, wherein said resilient member having an installed position corresponding to a generally frictional engagement with said nock bore and said shoulder portion, and an impact position corresponding to a generally compressed frictional engagement with said nock bore and said shoulder portion.

6. The nock assembly for use with an arrow, as set forth in claim 5, wherein said impact position being generally achieved during impact of the arrow, said impact of the arrow forces said shoulder portion of said groove towards said resilient member and said resilient member being generally compressed radially outward towards said nock bore.

7. The nock assembly for use with an arrow, as set forth in claim 6, wherein said power source being retained in said nock upon impact of the arrow.

8. The nock assembly for use with an arrow, as set forth in claim 6, wherein said power source being disengaged from said nock upon impact of the arrow.

9. The nock assembly for use with an arrow, as set forth in claim 8, wherein the arrow having a resilient impact member being disposed therein and said power source generally engaging said resilient impact member upon impact of the arrow.

10. The nock assembly for use with an arrow, as set forth in claim 1, wherein said pair of leads being in a generally fixed position relative to said nock.

11. The nock assembly for use with an arrow, as set forth in claim 10, wherein said generally fixed position being achieved using adhesive.

12. The nock assembly for use with an arrow, as set forth in claim 1, wherein said conductor has a first end generally extending through said nock bore to said outer surface of said nock and a second end generally positioned between said case and said nock bore and in electrical communication with said case.

13. The nock assembly for use with an arrow, as set forth in claim 1, wherein said conductor has a first end generally extending through another one of said at least one aperture to said outer surface of said nock and a second end being in generally coiled configuration and in electrical communication with said case.

14. A method of maintaining operability of a nock assembly upon impact of an arrow with a target, said arrow having a tubular arrow shaft having a bowstring defining an aiming position and a resilient impact member disposed therein, and said nock assembly having a first nock portion, a second nock portion, a step surface located between said first and second nock portions, a slot defined therein, and a power source having a resilient member disposed thereabout, the method comprises the steps of;

Inserting said first nock portion into said arrow shaft;

Positioning said bowstring in said slot;

Drawing said bowstring to said aiming position;

Releasing said bowstring;

Impacting said arrow with said target; and

Compressing said resilient member against said first nock portion of said nock assembly.

15. A method of maintaining operability of a nock assembly upon impact of an arrow with a target, as in claim 14, wherein the step of compressing said resilient member disengages said power source from said nock assembly, and said power source impacting said resilient impact member.
