Abstract

A projectile that includes a vibrating function is presented. The vibrating projectile, such as an arrow, is structured to penetrate flesh of an animal more easily than a standard projectile. After the arrow has reached its target, a switch turns on a vibrating mechanism that causes the arrowhead, such as a broadhead to vibrate as it is traveling into the animal. This deeper penetration causes more injury to the animal and reduces the time between arrow penetration and animal expiration.

Claims

1. A projectile, comprising:

an elongated shaft;

a cutting head coupled to the shaft; and

a vibrator structured to vibrate the cutting head of the projectile.

2. The projectile according to claim 1, further comprising:

a switch structured to control operation of the vibrator.

3. The projectile according to claim 2 in which the switch is structured to change from a first state to a second state when the projectile strikes the target.

4. The projectile according to claim 3 in which the switch is a mechanical or acceleration-sensing switch.

5. The projectile according to claim 2 in which the switch is disposed in one of the shaft, a threaded insert, the nock, or the cutting head of the projectile.

6. The projectile according to claim 2 in which the switch is disposed between a nock and the shaft, the shaft and a threaded insert, or between the threaded insert and the cutting head of the projectile.

7. The projectile according to claim 1 in which the projectile is an arrow and in which the cutting head is a broadhead.

8. The projectile according to claim 1 in which the vibrator is an electric motor, the projectile further comprising an energy source for the electric motor.

9. The projectile according to claim 1 in which the shaft is also structured to vibrate when the cutting head vibrates.

10. A broadhead structured to be inserted into a shaft of an arrow, the broadhead comprising a vibrator structured to vibrate the broadhead after or before the broadhead strikes a target.

11. The broadhead according to claim 10 in which the vibrator comprises:

a motor having a shaft;

an asymmetric weight coupled to the shaft; and

a power source to power the motor.

12. The broadhead according to claim 11, further comprising a switch to engage the motor only after the broadhead strikes the target.

13. An insert for insertion into an arrow shaft of an arrow, the threaded insert comprising a vibrator structured to vibrate the arrow after the arrow strikes a target.

14. The insert according to claim 13 in which the vibrator comprises:

a motor having a shaft;

an asymmetric weight coupled to the shaft; and

a power source to power the motor.

15. The insert according to claim 14, further comprising a switch to engage the motor only after the arrow strikes the target.

16. The insert according to claim 13 in which the insert is threaded.

17. An arrow shaft of an arrow, the arrow shaft comprising a vibrator structured to vibrate the arrow after the arrow strikes a target.

18. The arrow shaft according to claim 17 in which the vibrator comprises:

a motor having a shaft;

an asymmetric weight coupled to the shaft; and

a power source to power the motor.

19. The arrow shaft according to claim 17, further comprising a switch to engage the motor only after the arrow strikes the target.
