Abstract

This invention relates generally to an illuminated nock assembly and more particularly to an illuminating nock 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 nock has a step surface for sandwiching a first protrusion of the illumination member and a second protrusion of the conductor with the arrow shaft illuminating the nock assembly. 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, 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 a pair of apertures 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;

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 pair of apertures and another of said pair of leads extending through said nock bore and being in electrical communication with said case; and

a conductor being in electrical communication with said terminal and extending from said terminal through another of said pair of apertures.

2. The nock assembly, as set forth in claim 1, wherein said second portion of said nock having a slot disposed therein.

3. The nock assembly, as set forth in claim 1, wherein said nock being made of a translucent material.

4. The nock assembly, as set forth in claim 1, wherein said conductor adjacent said case being generally insulated.

5. The nock assembly, as set forth in claim 1, wherein said first nock portion having a power source holder partially disposed therein, said power source holder having a holder bore being defined by a second curvilinear surface and said longitudinal axis, said power source holder being partially disposed in said nock bore, and said power source holder being generally fastened to said first nock portion.

6. The nock assembly, as set forth in claim 5, wherein said power source being moveably extending into said holder bore.

7. The nock assembly, as set forth in claim 5, wherein said another one of said pair of leads being disposed between said case and said holder bore.

8. The nock assembly, as set forth in claim 5, wherein said conductor being disposed between said nock bore and said power source holder.

9. The nock assembly, as set forth in claim 5, wherein said power source holder being fastened to said first nock portion using material having adhesive characteristics.

10. The nock assembly, as set forth in claim 6, wherein said power source and said power source holder having a sleeve being disposed about at least a portion of said power source and at least a portion of said power source holder.

11. The nock assembly, as set forth in claim 10, wherein said sleeve being made of a shrinkable material.

12. A nock assembly for use with an electrically conductive tubular arrow shaft, 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 a pair of apertures generally adjacent to said step surface and opening into said nock bore, said first nock portion being moveably extending into said arrow shaft along said longitudinal axis;

a power source having a case generally abutting said first end of said nock, and a terminal;

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 pair of apertures and another of said pair of leads extending through said nock bore and being in electrical communication with said case;

a conductor being in electrical communication with said terminal and extending from said terminal through another of said pair of apertures;

a power source holder having a holder bore being defined by a second curvilinear surface and said longitudinal axis, said power source holder being partially disposed in said nock bore, and said power source holder being generally fastened to said first nock portion, and

a sleeve being disposed about at least a portion of said power source and at least a portion of said power source holder.

13. The nock assembly for use with an electrically conductive tubular arrow shaft, as set forth in claim 12, wherein said first nock portion moveably extending into said arrow shaft to a first position, and said first position being defined by said step surface being spaced from said arrow shaft and said first position corresponds to an open circuit between one of said pair of leads and said conductor.

14. The nock assembly for use with an electrically conductive tubular arrow shaft, as set forth in claim 12, wherein said first nock portion moveably extending into said arrow shaft to a second position, and said second position being defined by said step surface being forcibly engaged with said arrow shaft and said second position corresponds to a closed circuit between one of said pair of leads and said conductor.

15. The nock assembly for use with an electrically conductive tubular arrow shaft, as set forth in claim 14, wherein said second position sandwiches said one of said pair of leads and said conductor between said step surface and said arrow shaft.

16. The nock assembly for use with an electrically conductive tubular arrow shaft, as set forth in claim 14, wherein said second position illuminates said illumination member.
