Abstract

An adjustment system for a vertically adjustable bow sight includes a plurality of fiber optic set points and one fiber optic alignment point that is movable relative to the plurality of set points. Each fiber optic point, including the set points and alignment point is comprised of a terminal end of a length of fiber optic material, such as plastic optical fiber material. By adjusting the alignment point relative to the set points, the sight is vertically adjusted so as to adjust the sight pin of the sight for a particular distance-to-target.

Claims

1. An apparatus for adjusting a bow sight, comprising, comprising:

an adjustment mechanism for vertically adjusting a position of at least one sight pin of the bow sight;

a plurality of set point indicia, each set point indicia being defined by a terminal end of a first fiber optic element;

an adjustment indicia coupled to a vertical adjustment mechanism and selectively moveable relative to said plurality of set point indicia, said adjustment indicia being selectively alignable with one of said plurality of set point indicia for selectively adjusting the position of said at least one sight pin.

2. The apparatus of claim 1, further comprising a second fiber optic element having a terminal end defining said adjustment indicia.

3. The apparatus of claim 1, wherein each pair of said plurality of set point indicia are defined by opposite ends of a length of the first fiber optic element.

4. The apparatus of claim 3, further including a glow-in-the-dark material disposed in proximity to said length of the first fiber optic element.

5. The apparatus of claim 1, wherein said adjustment indicia is defined by a terminal end of a second fiber optic element.

6. The apparatus of claim 5, further including a spool coupled to said adjustment mechanism, said second fiber optic element of said adjustment indicia being at least partially wrapped around said spool.

7. The apparatus of claim 5, further including an elongate member supporting said second fiber optic element of said adjustment indicia for visually positioning said adjustment indicia over at least one of said plurality of set point indicia.

8. The apparatus of claim 6, further including a glow-in-the-dark material disposed between said spool and said second fiber optic element for illuminating said second fiber optic element in low light conditions.

9. The apparatus of claim 1, further comprising an arc-shaped bracket, said plurality of set point indicia being selectively positionable relative to said arc-shaped bracket.

10. An apparatus far adjusting a bow sight, comprising:

an adjustment mechanism for vertically adjusting a position of at least one sight pin of the bow sight;

a plurality of set point indicia arranged in a vertical array;

an adjustment indicia defined by a terminal end of a first fiber optic element, coupled to the vertical adjustment mechanism and selectively moveable relative to said plurality of set point indicia, said adjustment indicia being selectively alignable with one of said plurality of set point indicia for selectively adjusting the position of said at least one sight pin; and

each pair of said plurality of set point indicia defined by opposite terminal ends of a length of a second fiber optic element.

11. The apparatus of claim 10, further including a glow-in-the-dark material disposed in proximity to said length of the second fiber optic elements.

12. The apparatus of claim 10, further including a spool coupled to said adjustment mechanism, said first fiber optic element of said adjustment indicia being at least partially wrapped around said spool.

13. The apparatus of claim 12, further including an elongate member supporting said first fiber optic element of said adjustment indicia for visually positioning said adjustment indicia over at least one of said plurality of set point indicia.

14. The apparatus of claim 13, further including a glow-in-the-dark material disposed between said spool and said first fiber optic element for illuminating said first fiber optic element in low light conditions.

15. The apparatus of claim 10, further comprising a bracket having a substantially vertically oriented, arc-shaped portion, said plurality of set point indicia being selectively positionable relative to said arc-shaped portion.

16. An apparatus for adjusting a bow sight, comprising, comprising:

a sight head;

an adjustment mechanism for vertically adjusting a position of said sight head;

a plurality of set points oriented in a substantially vertical array, each set point being defined by a terminal end of a first fiber optic element;

an adjustment point defined by a terminal end of a second fiber optic element, said adjustment point being coupled to the vertical adjustment mechanism and selectively moveable relative to said plurality of set point indicia, said adjustment point being selectively alignable with one of said plurality of set points for selectively adjusting the position of said sight head.

17. The apparatus of claim 16, wherein each pair of said plurality of set points are defined by opposite ends of a length of said first fiber optic element.

18. The apparatus of claim 17, further including a glow-in-the-dark material disposed proximate to said first fiber optic element.

19. The apparatus of claim 16, further including a spool coupled to said adjustment mechanism, said second fiber optic element being at least partially wrapped around said spool.

20. The apparatus of claim 19, further including an elongate member supporting the terminal end of said second fiber optic element forming the adjustment point for visually positioning said adjustment point over at least one of said plurality of set point indicia.

21. The apparatus of claim 19, further including a glow-in-the-dark material disposed between said spool and said second fiber optic element for illuminating said second fiber optic element in low light conditions.

22. The apparatus of claim 16, further comprising a bracket having a substantially vertically oriented, arc-shaped portion, said plurality of set points being selectively positionable relative to said arc-shaped portion.

23. The apparatus of claim 22, wherein said arc-shaped bracket defines a substantially vertical slot therein forming a window therein through which each set point is visible to a user in an aiming orientation.

24. An apparatus for adjusting a bow sight, comprising, comprising:

an adjustment mechanism for vertically adjusting a position of at least one sight pin of the bow sight;

a vertically oriented mounting member;

a plurality of set point indicia independently, selectively, and vertically positionable relative to said vertically oriented mounting member, each set point indicia defined by a terminal end of a fiber optic element;

an adjustment indicia coupled to a vertical adjustment mechanism and selectively moveable relative to said plurality of set point indicia, said adjustment indicia being selectively alignable with one of said plurality of set point indicia for selectively adjusting the position of said at least one sight pin.

25. The apparatus of claim 24, wherein said adjustment indicia is defined by a terminal end of a fiber optic element.

26. The apparatus of claim 24, wherein each pair of said plurality of set point indicia are defined by opposite terminal ends of said fiber optic element.

27. The apparatus of claim 24, further including a glow-in-the-dark material disposed in proximity to at least a portion of said fiber optic element.

28. The apparatus of claim 25, further including a spool coupled to said adjustment mechanism, said fiber optic element of said adjustment indicia being at least partially wrapped around said spool.

29. The apparatus of claim 25, further including an elongate member supporting said fiber optic element of said adjustment indicia and horizontally extending from said adjustment mechanism for visually positioning said adjustment indicia over at least one of said plurality of set point indicia.
