Abstract

Systems and apparatuses of a crossbow including a stock defining a front end and a rear end, and a limb including: a fixed end affixed to the stock between the front end and the rear end, and a free end positioned between the front end and the rear end. The limb is configured to flex in a substantially vertical plane.

First claim

What is claimed is:

1. A crossbow, comprising:
a stock defining a front end, a rear end, and a projectile flight path;
a string let out assembly rotatably mounted to the stock and configured to rotate about an axis, the axis perpendicular to and vertically below the projectile flight path; and
a limb including:
a fixed end affixed to the stock between the front end and the rear end, and
a free end positioned between the front end and the rear end,

wherein the limb is configured to flex in a substantially vertical plane.

2. The crossbow of claim 1 , wherein the string let out assembly includes a drawstring groove configured to support a drawstring, and a cable groove configured to support a power cable coupled between the cable groove and the free end of the limb.

3. The crossbow of claim 1 , wherein the free end of the limb is positioned between the rear end and the axis.

4. The crossbow of claim 1 , wherein the axis is substantially perpendicular to the substantially vertical plane.

5. The crossbow of claim 1 ,
wherein the fixed end is affixed to the stock below the projectile flight path, and
wherein the free end is positioned above the projectile flight path.

6. The crossbow of claim 5 , wherein, during operation of the crossbow as the crossbow is drawn, the free end flexes toward the projectile flight path within the substantially vertical plane.

7. A crossbow, comprising:
a stock defining a projectile flight path;
a string let out assembly rotatably coupled to the stock about an axis of rotation perpendicular to and vertically below the projectile flight path, the string let out assembly including a drawstring groove configured to support a drawstring, and a cable groove configured to support a power cable; and
a limb including:
a fixed end affixed to the stock below the projectile flight path, and
a free end configured to couple to the power cable and flex in a substantially vertical plane.

8. The crossbow of claim 7 , wherein the substantially vertical plane is substantially perpendicular to the axis of rotation of the string let out assembly.

9. The crossbow of claim 7 , wherein the stock defines a front end and a rear end,
wherein the fixed end of the limb is affixed to the stock between the front end and the rear end, and
wherein the free end of the limb is positioned between the front end and the rear end.

10. The crossbow of claim 7 , wherein the stock defines a rear end, and
wherein the free end of the limb is positioned between the axis of rotation of the string let out assembly and the rear end.

11. The crossbow of claim 7 , wherein the stock defines a rear end, and
further comprising a trigger positioned between the axis of rotation of the string let out assembly and the rear end.

12. The crossbow of claim 7 , further comprising a second limb including:
a second fixed end affixed to the stock below the projectile flight path, and
a second free end configured to couple to a second power cable and flex in a second substantially vertical plane.

13. The crossbow of claim 12 , wherein a width defined by the limb and the second limb is less than about 4.5 inches.

14. A crossbow, comprising:
a stock defining a rear end and a projectile flight path;
a string let out assembly including:
a drawstring groove configured to support a drawstring,
a first cable groove configured to support a first power cable, and
a second cable groove configured to support a second power cable,
wherein the drawstring groove, the first cable groove, and the second cable groove rotate about an axis of rotation, wherein the axis of rotation is substantially perpendicular to and vertically below the projectile flight path;

a first limb including:
a first fixed end affixed to the stock between the rear end and the axis of rotation of the string let out assembly, and
a first free end configured to couple to the first power cable and flex in a first substantially vertical plane; and

a second limb including:
a second fixed end affixed to the stock between the rear end and the axis of rotation of the string let out assembly, and
a second free end configured to couple to the second power cable and flex in a second substantially vertical plane.

15. The crossbow of claim 14 ,
wherein the first fixed end and the second fixed end are affixed to the stock below the projectile flight path, and
wherein the first free end and the second free end are positioned above the projectile flight path.

16. The crossbow of claim 14 , further comprising a trigger positioned between the axis of rotation of the string let out assembly and the rear end.

17. The crossbow of claim 14 , wherein the first free end and the second free end are positioned between the axis of rotation of the string let out assembly and the rear end.

18. The crossbow of claim 14 , wherein the first limb and the second limb define a width less than about 8 inches.

19. The crossbow of claim 14 , wherein the first limb and the second limb define a width less than about 4.5 inches.
