Abstract

Arrowheads, including blade-opening arrowheads as well as other non blade-opening arrowheads having a recessed collar or body that is slidably positionable about a stem portion thereof. The recess bounds and defines an internally contained void of the arrowheads. The collar is defined by having an internal centrally disposed bore extending therethrough so as to enable the collar or washer to be slidably positioned about an extending post or stem member of a corresponding arrowhead body. The collar and created internal void at least in part aid in attaching blades to the respective arrowhead bodies and serve to house various different annular elements that circumscribe the post member or equivalent.

Claims

1. An arrowhead comprising:

(a) an arrowhead body having a central longitudinal axis, a forward end and an opposing rearward end;

(b) a stem disposed at the rearward end of the body; and

(c) a collar having a central through hole and an internally recessed substantially circular void, the void having a bounding internal wall that defines a diameter larger than the diameter defined by the central through hole, the arrowhead being configured such that the through hole of the collar is slidably disposed about the stem when the collar is attached to the body.

2. An arrowhead as recited in claim 1 wherein the circular void of the collar faces open toward the forward end of the arrowhead.

3. An arrowhead as recited in claim 1 wherein the stem has a diameter that is less than the diameter of a section of the arrowhead body located forward of the stem.

4. An arrowhead as recited in claim 1 wherein the circular void houses an annular entity when the collar is attached to the body.

5. An arrowhead as recited in claim 1 wherein when the collar is attached to the arrowhead body an internal circular cavity is created within the arrowhead, a section of the arrowhead body defining a forward most boundary of the cavity.

6. An arrowhead as recited in claim 5 wherein a ring is housed within the cavity.

7. An arrowhead as recited in claim 6 further comprising a cutting blade having an aperture formed therein, the cutting blade being attached to the body such that the ring extends through the aperture thereof.

8. An arrowhead as recited in claim 5 wherein a spring is housed within the cavity.

9. An arrowhead as recited in claim 5 wherein the arrowhead further comprises a blade receiving slot, the slot communicating with the cavity.

10. An arrowhead as recited in claim 5 wherein the cavity aids in attaching a cutting blade to the body.

11. An arrowhead as recited in claim 10 wherein the blade is moveable mounted to the body.

12. An arrowhead as recited in claim 10 further comprising a plurality of blades.

14. An arrowhead as recited in claim 13 wherein the cutting blade is movably attached to the body.

15. An arrowhead as recited in claim 14 wherein the cutting blade moves between a closed in-flight position and an open penetrating position.

16. An arrowhead as recited in claim 15, wherein the cutting blade moves in a rearward direction when opening from a closed in-flight position to an open penetrating position.

17. An arrowhead as recited in claim 15 further comprising a plurality of blades.

18. An arrowhead as recited in claim 14 wherein the cutting blade contacts at least a section of the collar when the arrowhead is in an open penetrating configuration.

19. An arrowhead as recited in claim 18 further comprising a plurality of blades.

20. An arrowhead as recited in claim 19 wherein the plurality of blades is three.

21. An arrowhead as recited in claim 13 wherein the body comprises an internally bounded annular recess disposed circumferentially about the stem having a substantially annular ring seated therein.

22. An arrowhead as recited in claim 21 wherein the annular recess having the annular ring seated therein communicates with the circular void of the collar.

23. An arrowhead as recited in claim 21 wherein the blade is hingedly attached to the body by the annular hinge ring.

24. An arrowhead as recited in claim 23 further comprising a plurality of blades.

25. An arrowhead as recited in claim 13 wherein the blade is attached to the body by an annular hinge ring.

26. An arrowhead as recited in claim 13 wherein the arrowhead body is fabricated from aluminum.

27. An arrowhead as recited in claim 26 wherein the arrowhead further comprises a steel tip attached to the body at the forward end thereof.

29. An arrowhead as recited in claim 28 further comprising a tip attached to the arrowhead body.

30. An arrowhead as recited in claim 28 wherein the blade is hingedly attached to the body by an annular hinge ring.

31. An arrowhead as recited in claim 30, wherein the blade moves in a rearward direction when opening from a closed in-flight position to an open penetrating position.

32. An arrowhead as recited in claim 28 wherein the internal void is configured such so as to receive an annular element therein.

33. An arrowhead as recited in claim 28, wherein the arrowhead is a blade-opening arrowhead.

34. An arrowhead as recited in claim 33, wherein the blade moves in a rearward direction when opening from a closed in-flight position to an open penetrating position.

35. An arrowhead as recited in claim 28, wherein the arrowhead comprises a plurality of blades.

13. An arrowhead comprising:

(a) an arrowhead body having a central longitudinal axis, a forward end and an opposing rearward end;

(b) a stem disposed at the rearward end of the body;

(c) a cutting blade attached to the body; and

(d) a collar having a central through hole and an exterior side wall extending thereabout, the arrowhead being configured such that the collar is slidably disposed about the stem, wherein the collar has an internally recessed substantially circular void bounded by the exterior side wall thereof, and the circular void faces open in a direction toward the forward end of the arrowhead body when the collar is attached to the arrowhead body.

28. An arrowhead comprising:

(a) an arrowhead body having a central longitudinal axis, a forward end and an opposing rearward end;

(b) a rearwardly extending stem disposed adjacent the rearward end of the body, the stem defining a first cross-sectional diameter;

(c) a barrel section of the arrowhead body located forward of at least a section of the stem, the barrel section defining a second cross-sectional diameter that is larger than the first cross-sectional diameter of the stem; and

(d) a collar having a through hole and a forward side, the collar being configured so at to slidably attach to the arrowhead body about the stem such that at least a portion of the forward side thereof contacts with at least a portion of the barrel section of the body, wherein the collar has an internal substantially circumferential void disposed rearward of the forward side thereof.
