Abstract

An controlled penetration arrow tip which has a penetration enhancing section at the point which is followed by an energy imparting or energy transferring section. This energy imparting section may resist complete penetration of an animal or penetration into unintended material, such as trees. The body and/or trailing end may be tapered to improve penetration or aerodynamic characteristics. Facets or scallops may be used on the impacting end, body, and/or trailing end in order to improve aerodynamic characteristics. The trailing end may be truncated, flared, flanged, or otherwise made larger than the arrow shaft to increase the damage of tissue and/or the energy transferring characteristics and/or to render removal from animal difficult. This truncated section may be split, cut, notched, or otherwise separated to improve aerodynamic and/or tissue damaging characteristics. Ribs, turbines, fins, blades, or other outwardly extending surfaces may be used to improve tissue damaging and/or aerodynamic characteristics.

Claims

1. An arrow tip consisting essentially of:

a body having an impacting end at one end of said body, a trailing end at the opposing end of said body, an interface between said body and said impacting end, and a longitudinal axis;

said impacting end having a centrally located point, said point being the apex of a first conical shaped small, in reference to said longitudinal axis, slope penetrating section having a surface which traverses across an intersection to a second conical shaped large, in reference to said longitudinal axis, slope energy imparting section having a surface and ending at said interface with said body;

the first slope section comprising a continuous line segment devoid of angular meeting points from said point to said intersection;

the second slope section comprising a continuous line segment devoid of angular meeting points from said intersection to said interface;

said body traversing into a truncated trailing end having a surface.

2. A tip according to claim 1, wherein said point is a diameter up to one-half the diameter of the body.

3. A tip according to claim 1, wherein the penetrating section is concave, said penetrating section having a surface.

4. A tip according to claim 3, wherein any tangent of said surface making an angle with said longitudinal axis is up to, but not including fifty degrees.

5. A tip according to claim 1, wherein the penetrating section is convex.

6. A tip according to claim 5, a plane extending between the point and the intersection of the penetrating and imparting sections making an angle with said longitudinal axis is up to but not including fifty degrees.

7. A tip according to claim 1, wherein the imparting section is concave, said imparting section having a surface.

8. A tip according to claim 7, wherein any tangent of said surface making an angle with said longitudinal axis is from fifty degrees up to but not including ninety degrees.

9. A tip according to claim 1, wherein the imparting section is straight, said imparting section having a surface.

10. A tip according to claim 9, wherein any angle said surface makes with the central longitudinal axis is from fifty degrees up to but not including ninety degrees.

11. A tip according to claim 1, wherein the imparting section is convex, said imparting section having a surface.

12. A tip according to claim 11, wherein any plane extending from the intersection of the penetrating and imparting sections to the interface between said imparting section and the body making an angle with said longitudinal axis is from fifty degrees up to but not including ninety degrees.

13. A tip according to claim 1, wherein said impacting end has a surface and said surface is continuous.

14. A tip according to claim 1, wherein said impacting end has a surface and said surface is discontinuous.

15. A tip according to claim 1, wherein the surface of said impacting end is faceted.

16. A tip according to claim 1, wherein said body is faceted.

17. A tip according to claim 1, wherein the surface of at least one of the slope sections is asymmetrical along the length of the surface.

18. An arrow tip comprising:

a body having an impacting end at one end of the body, a trailing end at the opposing end of said body, an interface between said body and said impacting end, and a longitudinal axis;

said impacting end having a centrally located point, said point being the apex of a first conical shaped small, in reference to said longitudinal axis, slope penetrating section having a surface which traverses across an intersection to a second conical shaped large, in reference to said longitudinal axis, slope energy imparting section having a surface and ending in the interface with said body;

the penetrating section is concave and any tangent of the surface of said penetrating section making an angle with said longitudinal axis is up to, but not including fifty degrees;

the imparting section is concave and any tangent of the surface of said imparting section making an angle with said longitudinal axis is from fifty degrees up to but not including ninety degrees;

said body traversing into a truncated trailing end.

19. A tip comprising:

a body having an impacting end at one end, a trailing end at the opposing end, a length, a surface, and a perimeter;

said trailing end having a length, surface, a perimeter, and at least one outwardly extending member or surface;

said outwardly extending member or surface having a longitudinal axis at an angle to a central longitudinal axis of said tip.

20. A tip according to claim 19, wherein said outwardly extending members or surfaces are continuous around said perimeter of said trailing end.

21. A tip according to claim 19, wherein said outwardly extending members or surfaces are discontinuous around said perimeter of said trailing end.

22. A tip according to claim 19, wherein said outwardly extending members or surfaces are discontinuous along the length of at least one of the body and said trailing end.

23. A tip according to claim 19, wherein said outwardly extending members or surfaces are a width of at least two percent of said perimeter of said tip.

24. A tip according to claim 19, wherein said outwardly extending members or surfaces are attached to said body.

25. A tip according to claim 19, wherein said outwardly extending members or surfaces are a part of the body.

26. A tip according to claim 19, wherein said outwardly extending members or surfaces are contoured in a manner selected from the group comprising twisted, spiral, helical, angled, chambered, and offset.

27. A tip according to claim 19, wherein the body is faceted.

28. A tip according to claim 19, wherein said trailing end is faceted.

29. A tip according to claim 19, wherein said outwardly extending surfaces are a portion of a wall around an annulus which is formed outward.

30. A tip comprising:

a body having an impacting end at one end, a trailing end at the opposing end, a length, a surface, and a perimeter;

said trailing end having a length, surface, a perimeter, and at least one outwardly extending member or surface, said outwardly extending members or surfaces are discontinuous around said perimeter of said trailing end or along the length of at least one of said body and said trailing end;

said outwardly extending member or surface having a longitudinal axis at an angle to a central longitudinal axis of said tip;
