Abstract

In at least one embodiment, a crossbow comprises a stock, a first limb, a first rotatable member, a second limb and a second rotatable member. A bowstring, a first cable and a second cable each extend between the first rotatable member and the second rotatable member. The crossbow defines a shooting axis. The first cable is offset from the shooting axis in a first direction and the second cable is offset from the shooting axis in a second direction different from the first direction.

First claim

The invention claimed is:

1. A crossbow comprising:
a stock, a first limb, a first rotatable member, a second limb and a second rotatable member;
a bowstring extending between the first rotatable member and the second rotatable member;
a first cable extending between the first rotatable member and the second rotatable member and a second cable extending between the first rotatable member and the second rotatable member;
a cable positioner attached to said stock, said cable positioner arranged to position said first cable, said cable positioner comprising a roller in contact with said first cable;
wherein the crossbow defines a shooting axis, the first cable is offset from the shooting axis in a first direction and the second cable is offset from the shooting axis in a second direction different from the first direction.

2. The crossbow of claim 1 , wherein the first cable is positioned above the shooting axis and the second cable is positioned below the shooting axis.

3. The crossbow of claim 1 , said cable positioner arranged to position said second cable.

4. The crossbow of claim 3 , said cable positioner comprising a second roller in contact with said second cable.

5. The crossbow of claim 4 , wherein said cable positioner comprises a body portion and said roller is arranged to move with respect to the body portion.

6. The crossbow of claim 5 , wherein said roller is moveable along a guide member axis, said guide member axis being parallel to said shooting axis.

7. The crossbow of claim 1 , comprising a second cable positioner attached to said stock, said second cable positioner arranged to position said first cable.

8. The crossbow of claim 7 , wherein said second cable positioner is arranged to position said second cable.

9. The crossbow of claim 7 , wherein said second cable positioner comprises a guide member arranged to move with respect to said stock.

10. The crossbow of claim 9 , wherein said guide member comprises a roller.

11. The crossbow of claim 10 , wherein said second cable positioner comprises a second roller.

12. The crossbow of claim 7 , wherein said cable positioner and said second cable positioner are attached to opposite sides of said stock.

13. The crossbow of claim 1 , wherein said roller is arranged to rotate about a central axis and traverse along said central axis.

14. The crossbow of claim 12 , said second cable positioner comprising a roller.

15. The crossbow of claim 1 , said cable positioner arranged to position said second cable.

16. The crossbow of claim 15 , comprising a second cable positioner arranged to position said first cable and said second cable.

17. The crossbow of claim 16 , wherein said cable positioner and said second cable positioner are located on opposite sides of said shooting axis.

18. A crossbow comprising:
a stock, a first limb, a first rotatable member, a second limb and a second rotatable member;
a bowstring extending between the first rotatable member and the second rotatable member;
a first cable extending between the first rotatable member and the second rotatable member;
a cable positioner attached to said stock, said cable positioner biasing said first cable in a first direction, said cable positioner biasing a second cable in a second direction different from said first direction, said cable positioner comprising a guide member in contact with said first cable, said guide member movable with respect to said stock;
wherein the crossbow defines a shooting axis, said stock extending below said shooting axis, the first cable positioned above said shooting axis.

19. The crossbow of claim 18 , said cable positioner comprising a second guide member in contact with said second cable, said second guide member moveable with respect to said stock.
