Abstract

A bow hunting broad-head system having a mechanical cutter which opens after impact. The broad-head flies to its destination with minimal drag and having good balance. After impact, the tip opens to a larger diameter creating a devastating wound and releases the payload inside the animal.

Claims

1. A payload delivery apparatus comprising;

(i) a combination arrow tip assembly and a payload, the tip assembly having a release mechanism;

(ii) wherein the payload is at least partially disposed within and held by the tip assembly and

(iii) is released from the tip assembly subcutaneously in a target animal

(iv) wherein the arrow tip further comprises a plurality of blades which separate to an open position after the arrow tip enters the target animal to release the payload at a predetermined depth.

2. The payload delivery apparatus in accordance with claim 1 wherein the payload comprises a device which carries at least one of;

a transmitter, a gas cartridge, a gps device, a stun capacitor, a noise maker, a blood thinner, a string attachment, a dye.

3. The payload delivery apparatus in accordance with claim 2 wherein the device further comprises a keyway.

4. The payload delivery apparatus in accordance with claim 3 wherein the device is integrated with the arrow tip assembly such that the keyway strengthens the plurality of blades during penetration of the animal hide.

5. The payload delivery apparatus in accordance with claim 4 wherein the keyway acts as a track for the respective blades to slide along to further force the blades to separate.

6. The payload delivery apparatus in accordance with claim 5 wherein the keyway disengages at a predetermined point leaving the payload free to deposit to one side or the other within the animal.

7. The payload delivery apparatus in accordance with claim 5 wherein the depth of release of the payload is independent of the open position diameter.

8. The payload delivery apparatus in accordance with claim 7 wherein the plurality of blades further comprises dual cutting surfaces.

9. The payload delivery apparatus in accordance with claim 8 wherein the dual cutting surfaces comprise a surface designed to cut hide and bone, and another surface for cutting internal organs.

10. A method for delivering a payload into the body of an animal comprising:

(i) providing a combination arrow tip assembly comprising a plurality of blades and a payload;

(ii) providing a release mechanism associated with the tip assembly device;

(iii) setting the blades in a closed position about the payload;

(iv) directing the combination arrow tip assembly toward the target animal in such a way that the release mechanism causes blades to open releasing the payload subcutaneously into the target animal.

11. The method for delivering a payload into the body of an animal in accordance with claim 10 wherein the release mechanism is a predetermined distance behind the arrow tip assembly.

12. The method for delivering a payload into the body of an animal in accordance with claim 11 wherein the payload further comprises a device which carries at least one of;

a transmitter, a gas cartridge, a gps device, a stun capacitor, a noise maker, a blood thinner, a string attachment, a dye.

13. The method for delivering a payload into the body of an animal in accordance with claim 11 wherein the device further comprises a keyway.

14. The method for delivering a payload into the body of an animal in accordance with claim 11 wherein the device is integrated with the arrow tip assembly such that the keyway strengthens the plurality of blades during penetration of an animal hide.

15. The method for delivering a payload into the body of an animal in accordance with claim 11 wherein the keyway acts as a track for the respective blades to slide along to further force the blades to separate.

16. The method for delivering a payload into the body of an animal in accordance with claim 11 wherein the blades continue to cut in the open position with a wider diameter than when in the closed position.

17. The method for delivering a payload into the body of an animal in accordance with claim 16 wherein the depth of release of the payload is controlled independently from the diameter of cut in the open position.

18. A payload delivery apparatus comprising a combination arrow tip assembly comprising:

(i) a plurality of blades which have the ability to pivot from a closed position to an open position,

(ii) a payload comprising a transmitter,

(iii) the tip assembly having a release mechanism;

(iv) wherein the payload is held by the tip assembly in a closed position and released from the tip assembly as the release mechanism reaches the hide of a target animal, causing the blades to separate to an open position at a predetermined position in the target animal

(v) whereby the payload is released.

19. The apparatus in accordance with claim 18 wherein the predetermined position is variable with relationship to an open diameter.
