Abstract

A projectile launcher includes a frame that has a front and rear end. A projectile is configured to be propelled from the front end of the frame and the projectile is movable along a projectile axis during firing and arming of the projectile launcher. The projectile launcher includes a latch movable between the rear end of the frame and the front end of the frame along a travel axis and is attached to a crank mechanism via a tether. The projectile launcher also includes flexible limbs that drive a drawstring of the projectile launcher during the firing of the projectile launcher.

First claim

What is claimed is:

1. A projectile launcher comprising:
a trigger for firing the projectile launcher;
a frame having a vertical grip, the frame defining a horizontal projectile plane at a top side in which a projectile axis is positioned, wherein a projectile moves within the horizontal projectile plane and along the projectile axis during firing and arming of the projectile launcher, wherein the projectile is fired from a front end of the frame; and
a limb arranged to flex in a vertical plane with a limb support arranged at a first end of the limb, the limb support being positioned rearward of the trigger.

2. The projectile launcher claim 1 , further comprising a medial limb support along a length of the limb.

3. The projectile launcher according to any one of the above claims of claim 2 , wherein the medial limb support is positioned in front of the trigger.

4. The projectile launcher of claim 2 , wherein the medial limb support is positioned rearward of the trigger.

5. The projectile launcher of claim 1 , wherein the projectile launcher comprises a second limb arranged to flex in a vertical plane with a limb support at the first end of the limb, and wherein the limb support is positioned rearward of the trigger.

6. The projectile launcher of claim 1 , further comprising a pulley mounted to the second end of the limb.

7. The projectile launcher of claim 1 , wherein the vertical grip is positioned in between the limb support and the trigger.

8. The projectile launcher of claim 1 , wherein the frame has a length between a front end and a rear end of the frame in a range from 15 inches to 23 inches.

9. The projectile launcher according to claim 1 , wherein the frame has a length of about 18.75 inches between the front and rear ends of the frame.

10. A projectile launcher comprising:
a frame having a vertical grip, the frame defining a horizontal projectile plane at a top side in which a projectile axis is positioned, wherein a projectile moves within the horizontal projectile plane and along the projectile axis during firing and arming of the projectile launcher, wherein the projectile is fired from a front end of the frame;
a string hub rotatably mounted to the frame, the string hub being rotatable about a central axis in a first direction and a second direction, the central axis being perpendicular to the projectile axis;
a drawstring being attached to the string hub, the drawstring traveling at least partially perpendicular to the projectile axis between first and second ends of the drawstring, the drawstring being movable within the projectile plane during firing and arming of the projectile launcher, wherein movement of the drawstring away from the string hub corresponds with rotation of the string hub in the first direction, and wherein movement of the drawstring toward the string hub corresponds with rotation of the string hub in the second direction;
a first and a second flexible limb attached to the frame, wherein the first and second limbs are arranged to flex in a vertical plane when the projectile launcher is drawn, and wherein each of the first and second limbs are supported rearward of the vertical grip by a limb support at a first end of the first and second limbs; and
a first and a second power cable each having a first end and a second end, wherein the first ends of the first and second power cables are attached to the string hub, wherein upon rotation of the string hub in the first direction, the first and second power cables are configured to draw the first and second flexible limbs closer to the string hub.

11. The projectile launcher of claim 10 , wherein each of the first and second limbs are supported by a medial limb support between their first end and second end.

12. The projectile launcher of claim 11 , wherein the medial limb support is positioned in front of the vertical grip.

13. The projectile launcher of claim 11 , wherein the medial limb support is positioned rearward of the vertical grip.

14. The projectile launcher of claim 10 , further comprising a pulley positioned at the second end of each of the first and second flexible limbs.

15. The projectile launcher of claim 10 , wherein the string hub is positioned in front of the vertical grip.

16. The projectile launcher of claim 10 , further comprising a stock mounted to the rear of the frame, wherein the limb support is positioned in between the vertical grip and the stock.

17. The projectile launcher of claim 10 , wherein the frame has a length between a front end and a rear end of the frame in a range from 15 inches to 23 inches.

18. The projectile launcher of claim 10 , wherein the frame has a length of 18.75 inches between the front and rear ends of the frame.

19. The projectile launcher of claim 10 , wherein the first and second limbs extend upwardly and over the vertical grip.

20. A projectile launcher comprising:
a frame having a grip positioned underneath and configured to fire a projectile from a front;
a trigger coupled to the frame and selectable to release the projectile;
a limb support connected to the frame rearward of the trigger; and
a limb connected at an end to the limb support and configured to flex in a vertical plane.
