Abstract

A blade opening arrowhead having an actuator moveably mounted with respect to a blade carrying body. The actuator can move each blade between a closed position and an opened position. During flight, the blade is in the closed position. Upon target penetration, for example, the actuator moves the blade into the opened position.

Claims

1. A blade opening arrowhead, comprising:

a blade carrying body, an actuator movably mounted with respect to the blade carrying body, a blade movably mounted with respect to the actuator and movably mounted with respect to the blade carrying body, and a movement of the actuator with respect to the blade carrying body pivoting the blade about a pivot axis that is fixed with respect to the actuator and moving the blade with respect to the blade carrying body.

2. A blade opening arrowhead according to claim 1, wherein the actuator is slidably mounted with respect to the blade carrying body.

3. A blade opening arrowhead according to claim 1, wherein the blade carrying body has a channel and at least a portion of the actuator is slidably mounted within the channel.

4. A blade opening arrowhead according to claim 1, wherein at least a portion of the actuator extends outward and beyond an external surface of the blade carrying body.

5. A blade opening arrowhead according to claim 1, wherein during the movement of the actuator the pivot axis of the blade moves with respect to the blade carrying body.

6. A blade opening arrowhead according to claim 1, wherein the actuator has a plurality of actuation surfaces each extending outward and beyond an outer surface of the blade carrying body, and the actuation surfaces are equally spaced about a periphery of the blade carrying body.

7. A blade opening arrowhead according to claim 1, wherein as the blade opening arrowhead passes through a target material, at least a portion of the actuator contacts the target material.

8. A blade opening arrowhead according to claim 1, wherein movement of the actuator with respect to the blade carrying body moves the blade between a closed position and an opened position.

9. A blade opening arrowhead according to claim 8, wherein a bias element releasably contacts and holds the blade in the closed position.

10. A blade opening arrowhead according to claim 9, wherein a force generated by movement of the actuator overcomes a retaining force of the bias element and allows the blade to move from the closed position to the opened position.

11. A blade opening arrowhead according to claim 1, wherein the body forms a slot, and a portion of the blade is mounted within the slot.

12. A blade opening arrowhead according to claim 1, wherein the blade has a back surface that slidingly contacts a contact portion of the blade carrying body when the blade moves between the closed position and the opened position.

13. A blade opening arrowhead according to claim 12, wherein the back surface is straight or curved.

14. A blade opening arrowhead according to claim 12, wherein the back surface and the contact portion form a line contact with respect to each other.

15. A blade opening arrowhead according to claim 1, wherein a shaft connects two body portions of the actuator.

16. A blade opening arrowhead according to claim 1, wherein a cutting diameter of the arrowhead in the opened position is greater than in the closed position.

17. A blade opening arrowhead according to claim 1, wherein a shaft fixedly positioned with respect to the actuator or the blade pivotally mounts the blade with respect to the actuator.
