Abstract

A hunting broadhead for attachment to an arrow used in bow hunting of a game animal having two thin flat metal elongated blades juxtaposed each other pivotally secured in a slot situated in a rearwardly located tubular body. Each blade has a pointed first end adapted to precede the arrow in flight for penetration of the animal'"'"'s hide and initial movement into the animal. Each blade has one sharpened lengthwise side and one blunted side with the outstanding spur, the blunted sides extending outwardly of the sharpened sides when the pointed front ends overlap permitting an elastic band to encompass both said blades to maintain such configuration for flight and initial penetration of the animal. After penetration into the game animal, rearwardly located outwardly protruding spurs engage the animal'"'"'s hide causing a metamorphosis whereupon the blades rotate with the rear moving to the front to become the forward leading point. After rotation, the sharpened blades become the leading members of the wide "V" configuration for continued movement through the animal to effect a clean kill.

Claims

1. A hunting broadhead for attachment to an arrow used in bow hunting of a game animal which has a pointed end for flight, for penetration of the animal'"'"'s hide, and for initial movement into the animal thereafter metamorphosing into a sharpened wide "V" configuration for continued movement through the animal, said hunting broadhead comprising:

a body adapted to be attached to the arrow;

an elongated first blade having a first end and a second end, said first end terminating in a point, and a spaced apart first side and second side each having a length running from said first end to said second end, said second side having an outstanding spur with a forward portion and a rearward portion, said first side having a sharpened edge from a second location near but behind said point to said second end and said second side having a blunted edge from said first end to and including said spur forward portion, said first and second side edge converging towards each other from a first location adjacent said spur to said second location, said second side edge being angled towards said first side edge from said second location and extending to meet said first side edge at said point, said first blade pivotally attached to said body proximate said second end;

an elongated second blade having a first end and a second end, said first end terminating in a point, and a spaced apart first side and second side each having a length running from said first end to said second end, said second side having an outstanding spur with a forward portion and a rearward portion, said first side having a sharpened edge from a second location near but behind said point to said second end and said second side having a blunted edge from said first end to and including said spur forward portion, said first and second side edge converging towards each other from a first location adjacent said spur to said second location, said second side edge being angled towards said first side edge from said second location and extending to meet said first side edge at said point, said second blade pivotally attached to said body proximate said second end;

said first and second blade being pivotal to and extending forward of said body in an orientation such that said blunted side edge of said first blade is on opposite sides from said blunted side edge of said second blade; and

means securing said first and said second blade together to hold said first end of both said first blade and said second blade in an overlap configuration to form a single pointed end for flight with said blunted side edge of each said second side of each blade extending outwardly beyond said sharpened edge of each said first side from said first location to said second location, and said encompassing means together with said second blunted side wedge of both said first blade and second blade maintaining said first and second blade in a single point configuration during penetration and initial movement into the animal until said forward portion of each said spur engages the animal'"'"'s hide to cause both said first and second blade to pivot about each said respective second end to present each said sharpened first side as a leading member in a sharpened wide "V" configuration for continued movement through the game animal for a clean kill.

2. The hunting broadhead as defined in claim 1 wherein said means securing said first and said second blade permits the pivoting of each said first and second blade upon each said spur engaging the animal'"'"'s hide.

3. The hunting broadhead as defined in claim 2 wherein said securing means defines means tying said first and said second together in a closed pointed end configuration.

4. The hunting broadhead as defined in claim 2 wherein said securing means defines an elastic band encompassing both said first and said second blade to maintain the closed pointed end configuration.

5. The hunting broadhead as defined in claim 4 wherein said means securing said first and said second blade defines said elastic band situated at said first location of each said blade.

6. The hunting broadhead as defined in claim 2 wherein said securing means defines an adhesives situated between said first blade and said second blade.

7. The hunting broadhead as defined in claim 6 wherein said adhesive is situated proximate said first end of both said first blade and said second blade.

8. The hunting broadhead as defined in claim 2 wherein said means securing said first and second blade defines a concave detect in said second blade and a convex detent in said first blade whereupon said detects engage each other to hold said first blade and said second blade together in a closed pointed end configuration.

9. The hunting broadhead as defined in claim 8 wherein a detect securing means is situated proximate said first end of said first blade and said second blade.

10. The hunting broadhead as defined in claim 2 wherein said both said elongated first and second blade second end terminates in a right angle foot, said right angle foot of said first blade and said second blade overlapping to form a leading sharpened point of the sharpened wide "V" configuration for further movement through the game animal.

11. The hunting broadhead as defined in claim 10 further including a first stop formed in each said second side of said first blade and said second blade proximate said second end, each said first stop engaging said body when said first blade and said second blade first end overlaps in the single pointed end configuration.

12. The hunting broadhead as defined in claim 11 further including a second stop formed in each said second side of said first blade and said second blade proximate said spur rearward portion, said second stop engaging said body to maintain said first blade and said second blade in the sharpened wide "V" configuration for continued movement through the animal.

13. The hunting broadhead as defined in claim 12 wherein said body defines a cylindrical body which includes a slot and a pivot pin, said pivot pin transverse to and crossing said slot, both said first blade and said second blade partially residing in said slot and pivoting about said pivot pin.
