Abstract

An arrow broadhead having a pair of cutting blades held in a retracted position during arrow flight and extending outwardly in an expanded position upon arrow contact. The subject broadhead includes a pair of pivot arms or sliding arm received in an elongated groove in a cutting blade housing body. The pivot arms or sliding arm are attached to one end of the cutting blades. At least a portion of the cutting blades are folded into the groove during arrow flight. Upon target contact, the pivot arms or sliding arm pivot the cutting blades outwardly from opposite sides of the groove into an expanded position for increased cutting and penetration in the target.

Claims

1. An arrow broadhead comprising:

a housing body having at least one elongated aperture extending through at least a portion of the housing body;

a tip coupled to the housing body;

at least one elongated generally cylindrical arm disposed at least partially within the elongated aperture and rearward of the tip, the at least one arm configured to move independently from the tip; and

first and second cutting blades disposed at least partially within the elongated aperture and pivotally coupled to the at least one arm;

wherein the first and second cutting blades are configured to pivot outward relative to the housing body as the at least one arm moves rearward relative to the housing body within the elongated aperture;

wherein the first and second cutting blades each have a cutting edge and an inside edge, each inside edge having a protruding portion extending from the cutting blade.

2. The arrow broadhead of claim 1, wherein the at least one arm is pivotally coupled to the housing body.

3. The arrow broadhead of claim 1, wherein the at least one arm is configured to slide rearward within the elongated aperture in the housing body.

4. The arrow broadhead of claim 1, wherein the at least one arm comprises a pair of moveable arms disposed at least partially within the elongated aperture in the housing body.

5. The arrow broadhead of claim 1, wherein each cutting blade defines an elongated window therethrough.

6. The arrow broadhead of claim 1, wherein, at least in a retracted position, the first cutting blade extends through a first side of the aperture and protrudes out a second, opposite side of the aperture.

7. The arrow broadhead of claim 1, wherein the tip comprises a blade.

8. The arrow broadhead of claim 1, wherein a cutting blade has a recess configured to receive a curved portion of a spring mechanism.

9. The arrow broadhead of claim 1, wherein, at least in a retracted position, the first cutting blade extends through a first side of the aperture and protrudes out a second, opposite side of the aperture.

10. The arrow broadhead of claim 1, wherein the tip comprises a cutting blade.

11. The arrow broadhead of claim 1, wherein the tip is at least one of press fit, glued or threaded into a portion of the housing body.

12. An arrow broadhead comprising:

a housing body having at least one elongated aperture extending through at least a portion of the housing body;

a tip coupled to the housing body;

at least one elongated generally cylindrical arm disposed at least partially within the elongated aperture and rearward of the tip, the at least one arm configured to move independently from the tip; and

first and second cutting blades disposed at least partially within the elongated aperture and pivotally coupled to the at least one arm;

wherein the first and second cutting blades are configured to pivot outward relative to the housing body as the at least one arm moves rearward relative to the housing body within the elongated aperture,

wherein at least one of the first and second cutting blades has a recess configured to receive a curved portion of a spring mechanism for retaining the at least one cutting blade in a retracted position.

13. The arrow broadhead of claim 12, wherein the first and second cutting blades each have a cutting edge and an inside edge, each inside edge having a protruding portion extending from the cutting blade.

14. The arrow broadhead of claim 13, wherein each cutting blade defines an elongated window therethrough.

15. The arrow broadhead of claim 14, wherein, at least in a retracted position, the first cutting blade extends through a first side of the aperture and protrudes out a second, opposite side of the aperture.

16. The arrow broadhead of claim 12, wherein the tip comprises a blade.

17. An arrow broadhead, comprising:

a housing body having at least one elongated aperture extending through at least a portion of the housing body;

at least one elongated generally cylindrical arm disposed at least partially within the elongated aperture; and

first and second cutting blades pivotally coupled to the at least one arm, wherein at least a portion of each of the first and second cutting blades is exposed outside the housing body in a retracted position, wherein the first and second cutting blades are configured to pivot outward relative to the housing body from the retracted position to an extended position as the at least one arm moves rearward relative to the housing body within the elongated aperture.

18. The arrow broadhead of claim 17, further comprising:

a tip coupled to the housing body;

wherein the at least one elongated generally cylindrical arm is disposed rearward of the tip, the at least one arm configured to move independently from the tip;

wherein the first and second cutting blades are disposed at least partially within the elongated aperture; and

an O-shaped metal ring configured to hold the at least one arm or at least one of the first and second cutting blades in a retracted position.

19. The arrow broadhead of claim 18, wherein, at least in the retracted position, the first cutting blade extends through a first side of the aperture and protrudes out a second, opposite side of the aperture.

20. The arrow broadhead of claim 19, wherein the tip is removable.
