Abstract

A bow string release for engaging and releasing a bow string, comprising opposing jaws, a trigger, a housing, a jaw roller and a plurality of pins, the opposing jaws and the trigger coupled to the housing by pins, and the jaw roller coupled to the trigger and allowing the opposing jaws to an open condition when the trigger is in a pulled position. The bow string release of the present invention is adapted to minimize “loading up” of trigger force required to pull the trigger at full draw of a bow. Further the bow string release of the present invention is adapted to release the bow string at a trigger pull force of equal to or less than 9 ounces when an effective draw weight of the bow is equal to or more than 15 pounds.

Claims

1. A bow string release for engaging and releasing a bow string, comprising:

opposing jaws;

a trigger;

a jaw roller moveable between a forward position closest to the bow string, and a back position;

the jaw roller coupled to the trigger and slidably engaged with the opposing jaws and allowing the opposing jaws to move between a closed position when said jaw roller is in position to an open position when said jaw roller is in said back position.

2. A bow string release according to claim 1, the release further comprising an axle link coupled between the trigger and the jaw roller.

3. A bow string release according to claim 1, the release further comprising a reset spring biased to urge the trigger to urge the roller to urge the jaws to the closed position.

4. A bow string release according to claim 1, the release further comprising a jaw spring retained between the opposing jaws that urges the opposing jaws to the open position when the trigger is pulled.

5. A bow string release according to claim 1, the opposing jaws each having a jaw spring receiver for carrying the spring.

6. A bow string release according to claim 1, the jaw roller further allowing the opposing jaws to the closed condition when the trigger is released from the pulled position.

7. A bow string release according to claim 1, the release further comprising a means for adjusting a pull force required to pull the trigger to the pull position.

8. A bow string release according to claim 7, wherein the pull force is adjustable to less than 9 ounces at an effective draw weight of 15 pounds.

9. A bow string release according to claim 1, the release further comprising an trigger sensitivity adjustable screw coupled to the trigger and allowing for trigger sensitivity adjustment.

10. A bow string release according to claim 9, wherein the trigger sensitivity adjustment is adjustable to less than 9 ounces at an effective draw weight of 15 pounds.

11. A bow string release according to claim 9, wherein a loosening of the trigger sensitivity adjustable screw decreases a distance that the trigger must travel to release the bow string.

12. A bow string release according to claim 1, the release further comprising:

a housing;

a pin, the pin coupling the trigger to the housing.

13. A bow string release according to claim 1, the release further comprising a plurality of jaw pins, the jaw pins coupling the opposing jaws to a housing.

14. A bow string release according to claim 1, at least one of the opposing jaws comprising:

a closed condition roller receiver adapted to receive the jaw roller in the closed condition;

a roller receiver ridge;

an open condition roller receiver adapted to receive the jaw roller in the open position;

said roller receiver ridge positioned between said closed condition roller receiver and open closed condition roller receiver.

15. A bow string release according to claim 14, wherein the closed condition roller receiver is formed by a closed condition roller receiver forward angled surface and a closed condition roller receiver substantially parallel surface.

16. A bow string release for engaging and releasing a bow string, the bow string release adapted to release the bow string by pulling a trigger with a pull force of equal to or less than 40 ounces when an effective draw weight of the bow is equal to or more than 50 pounds.

17. A bow string release for engaging and releasing a bow string, the bow string release adapted to release the bow string by pulling a trigger with a pull force of equal to or less than 30 ounces when an effective draw weight of the bow is equal to or more than 50 pounds.

18. A bow string release for engaging and releasing a bow string, the bow string release adapted to release the bow string by pulling a trigger with a pull force of equal to or less than 20 ounces when an effective draw weight of the bow is equal to or more than 50 pounds.

19. A bow string release for engaging and releasing a bow string, the bow string release adapted to release the bow string by pulling a trigger with a pull force of equal to or less than 10 ounces when an effective draw weight of the bow is equal to or more than 25 pounds.

20. A bow string release for engaging and releasing a bow string, the bow string release adapted to release the bow string by pulling a trigger with a pull force of equal to or less than 9 ounces when an effective draw weight of the bow is equal to or more than 15 pounds.

21. A bow string release for engaging and releasing a bow string, the bow string release adapted to release the bow string by pulling a trigger with a pull force of equal to or less than 8 ounces when an effective draw weight of the bow is equal to or more than 15 pounds.

22. A bow string release for engaging and releasing a bow string, the bow string release adapted to release the bow string by pulling a trigger with a pull force of equal to or less than 7 ounces when an effective draw weight of the bow is equal to or more than 15 pounds.

23. A bow string release for engaging and releasing a bow string, the bow string release adapted to release the bow string by pulling a trigger with a pull force of equal to or less than 6 ounces when an effective draw weight of the bow is equal to or more than 15 pounds.

24. A method of releasing a bow string with a bow string release comprising:

grasping the bowstring with jaws carried by the bow string release;

engaging with a finger a trigger carried by the bow string release;

drawing the bow string back to a firing position;

creating an effective draw weight of the bow of equal to or more than 25 pounds;

pulling the trigger with the finger with a pull force of equal to or less than 10 ounces to release the bow string.

25. A method of releasing a bow string with a bow string release comprising:

grasping the bowstring with jaws carried by the bow string release;

engaging with a finger a trigger carried by the bow string release;

drawing the bow string back to a firing position;

creating an effective draw weight of the bow of equal to or more than 15 pounds;

pulling the trigger with the finger with a pull force of equal to or less than 9 ounces to release the bow string.

26. A method of releasing a bow string with a bow string release comprising:

grasping the bowstring with jaws carried by the bow string release;

engaging with a finger a trigger carried by the bow string release;

drawing the bow string back to a firing position;

creating an effective draw weight of the bow of equal to or more than 15 pounds;

pulling the trigger with the finger with a pull force of equal to or less than 8 ounces to release the bow string.
