Abstract

A hunting arrow having an arrow shaft with a front end and a back end. The hunting arrow has at least one arrow blade attached to the arrow shaft, and has a closed position and at least one open position. The at least one arrow blade is substantially flush with the arrow shaft when in the closed position, and extends radially outward from the arrow shaft when in an open position. In addition, the hunting arrow has an arrow tip that is attached to the front end of the arrow shaft and is capable of moving longitudinally toward or away from the arrow shaft. The arrow tip is operatively engaged with the at least one arrow blade so that the arrow tip opens and closes the at least one arrow blade by moving relative to the arrow shaft.

Claims

1. A hunting arrow, comprising:

an arrow shaft having first and second ends, the first end configured to removably couple with an arrow tip;

at least one elongated opening in the shaft, the opening having a front end and a back end;

a pivot disposed within the shaft adjacent the at least one opening; and

a plurality of arrow blades wherein each blade comprises a front tip, a back portion, and a slot configured to engage the pivot, and wherein each blade is sized relative to the opening to facilitate the blade passing through the opening, and wherein each blade is coupled to the pivot so that the blade is disposed within the shaft in a closed condition and protrudes from the shaft in an open condition, and wherein one open condition comprises the front tip of the at least one blade being past a point of zenith relative to the pivot along the shaft.

2. The arrow according to claim 1 further comprising a fixed broad head tip.

3. The arrow according to claim 2 wherein the at least one arrow blade comprises a tab.

4. The arrow according to claim 3 wherein the tab of the at least one arrow blade protrudes from the shaft when the blade is in the closed condition.

5. The hunting arrow of claim 1, comprising:

a cartridge located within the extended arrow shaft and configured to support the at least one blade in the open condition.

6. An apparatus for hunting, comprising:

an arrow shaft having an outside surface, first and second ends, with the first end configured to removably couple with an arrow tip and a second end having a nock;

at least one elongated opening through the shaft, the opening having a front end and a back end;

at least one arrow blade rotatably coupled to the shaft and comprising a front tip, a back portion, a tab comprising a front and a back, and a slot, all configured such that at least a portion of a surface of the at least one arrow blade is located within the arrow shaft in a closed condition, and the at least one arrow blade is configured to extend outward from the shaft in an open condition; and

a pivot disposed within the body adjacent the at least one opening and configured to engage the blade slot so that each blade can transition through the opening from the closed condition to the open condition about the pivot, wherein one open condition comprises the back of the tab being in substantial contact with a portion of the outside surface of the shaft at a location between the back end of the elongated opening and the second end of the arrow shaft.

7. The apparatus according to claim 6 further comprising a fixed broad head tip.

8. The apparatus according to claim 6 wherein the at least one blade travels radially outward from the extended shaft from the closed condition to the open condition after the arrow contacts a target.

9. The apparatus according to claim 6 where at least 50% of the at least one arrow blade is located within the arrow shaft.

10. The apparatus according to claim 6 wherein the tab of the at least one arrow blade is retractable.

11. The apparatus according to claim 6 wherein the at least one blade travels radially outward from the shaft from the closed condition to the open condition after the tab contacts a target.

12. An arrow shaft, comprising:

a body having first and second ends, the first end configured to removably couple with an arrow tip;

at least one blade having a front tip, and a back portion;

a slot formed in the back portion of the at least one blade, the slot comprising a rear end and a front end;

at least one elongated opening in the body through an outside surface of the body, the opening having a front end and a back end and configured to allow the at least one blade to pass there through;

a pivot disposed within the body adjacent the at least one opening and configured to engage the slot so that the at least one blade can transition through the opening from a closed position to a first opened position about the pivot;

the closed position defined by the tip of the blade being substantially flush with the body and the pivot being located adjacent the rear end of the slot, but not contacting the rear end of the slot; and

the first opened condition defined by the tip of the blade being exposed from the body.

13. The component of claim 12, comprising a surface disposed within the body and adjacent the front end of the opening and configured so that the blade tip contacts the surface when the at least one blade is in the closed position.

14. The component of claim 13, comprising a cartridge disposed within the body adjacent the back portion of the at least one blade and configured to support the at least one blade in a fully opened position.

15. The component of claim 14, wherein the at least one blade defines an obtuse angle in the fully opened position relative to the body.

16. The component of claim 13, comprising a frangible device disposed external to the opening to selectively bias the at least one blade to the closed position.

17. The component of claim 16, wherein the device is an o-ring.

18. The component of claim 13 wherein the blade is configured to move relative to the surface upon deceleration of the body.

19. The component of claim 13, wherein the at least one blade comprises a tab, and the blade moves toward the open position after the tab contacts a target.

20. The component of claim 12, wherein the at least one blade is configured to move relative to the pivot upon a change in acceleration of the body.
