Abstract

Collars are provided to facilitate retaining the blades of a broadhead in their in-flight position during flight. Collars can be used in situations where the preexisting use of an O-ring is used to help facilitate maintaining the blades of a broadhead in their in-flight position during flight. Collars can also be used in situations where the preexisting use of an O-ring is not used to help facilitate maintaining the blades of a broadhead in their in-flight position during flight.

Claims

1. An expandable broadhead comprising:

an annular collar comprising a plurality of slots and a corresponding plurality of leaves, each leaf positioned between a respective pair of slots;

wherein at least two of the plurality of leaves respectively contact a blunt edge of a blade of the expandable broadhead; and

wherein the at least two of the plurality of leaves flex radially outward when the expandable broadhead impacts a target.

2. The expandable broadhead of claim 1, further comprising an O-ring inserted into an internal diameter of the annular collar.

3. The expandable broadhead of claim 2, wherein there is a friction fit between the O-ring and the internal diameter of the annular collar.

4. The expandable broadhead of claim 1, wherein the plurality of slots comprise six slots, and the plurality of leaves comprise six leaves.

5. The expandable broadhead of claim 1, comprising a groove that circumferentially extends along an inner wall of a lower portion of each of the plurality of leaves.

6. The expandable broadhead of claim 5, wherein the groove is configured to facilitate the at least two of the plurality of leaves to flex radially outward.

7. The expandable broadhead of claim 6, wherein the groove is configured to facilitate the at least two of the plurality of leaves to break off of the annular collar.

8. An expandable broadhead comprising:

an annular collar comprising a plurality of slots and a corresponding plurality of leaves, each leaf positioned between a respective pair of slots;

wherein at least two of the plurality of leaves respectively contact a blunt edge of a blade of the expandable broadhead, the blade in a secured position prior to the expandable broadhead impacting a target;

wherein the at least two of the plurality of leaves flex radially outward when the expandable broadhead impacts the target.

9. The expandable broadhead of claim 8, further comprising an O-ring inserted into an inner diameter of the annular collar.

10. The expandable broadhead of claim 9, wherein there is a friction fit between the O-ring and the inner diameter of the annular collar.

11. The expandable broadhead of claim 8, wherein the plurality of slots comprise six slots, and the plurality of leaves comprise six leaves.

12. The expandable broadhead of claim 8, comprising a groove that circumferentially extends along an inner wall of a lower portion of each of the plurality of leaves.

13. The expandable broadhead of claim 12, wherein the groove is configured to facilitate the at least two of the plurality of leaves to flex radially outward.

14. The expandable broadhead of claim 13, wherein the groove is configured to facilitate the at least two of the plurality of leaves to break off of the annular collar.

15. An annular broadhead collar comprising:

a plurality of slots;

a corresponding plurality of leaves, each leaf positioned between a respective pair of slots; and

a groove that circumferentially extends along an inner wall of the plurality of leaves, wherein the groove is configured to facilitate breakage of the annular broadhead collar at the positions of the plurality of slots.

16. The annular broadhead collar of claim 15, further comprising a V-shaped groove that circumferentially extends along an outer wall of the annular broadhead collar.

17. The annular broadhead collar of claim 16, wherein the annular broadhead collar comprises a first portion and a second portion, the plurality of leaves are positioned on the first portion, and the groove is positioned at an interface of the first portion and the second portion.
