Abstract
Provided is a crossbow comprising a bow having: a riser having a first riser side and a second riser side; a first cam set having a first shaft, a first power cord cam of the first cam set, a bowstring cam, and a second power cord cam of the first cam set; a second cam set having a second shaft, a first power cord cam of the second cam set, a bowstring cam, and a second power cord cam of the second cam set; a first power cord engaged with the first power cord cam of the first cam set and the first riser side; a second power cord engaged with the first power cord cam of the second cam set and the second riser side; and a third power cord engaged between the second power cord cams
Claims19
A crossbow comprising
- a bow having
- a riser having
- a first riser side and
- a second riser side opposite the first riser side,
- a first limb set
- engaged to the first riser side, and
- defining a first limb axis;
- a second limb set,
- engaged to the second riser side, and
- defining a second limb axis parallel to the first limb axis;
- a first cam set having
- a first shaft defining and rotatable about a first cam axis, the first shaft engaged with the first limb set such that the first cam axis coincides with the first limb axis,
- a first power cord cam of the first cam set operationally engaged with the first shaft to be rotatable about the first cam axis,
- a bowstring cam of the first cam set operationally engaged with the first shaft to be rotatable about the first cam axis,
- a second power cord cam of the first cam set operationally engaged with the first shaft to be rotatable about the first cam axis;
- a second cam set having
- a second shaft defining and rotatable about a second cam axis, the second shaft engaged with the second limb set such that the second cam axis coincides with the second limb axis,
- a first power cord cam of the second cam set operationally engaged with the second shaft to be rotatable about the second cam axis,
- a bowstring cam of the second cam set operationally engaged with the second shaft to be rotatable about the second cam axis,
- a second power cord cam of the second cam set operationally engaged with the second shaft to be rotatable about the second cam axis;
- an elongated first power cord having
- a first end of the elongated first power cord operationally engaged with the first power cord cam of the first cam set, and
- a second end of the elongated first power cord opposite the first end of the elongated first power cord operationally engaged with the first riser side;
- an elongated second power cord having
- a first end of the elongated second power cord operationally engaged with the first power cord cam of the second cam set, and
- a second end of the elongated second power cord opposite the first end of the elongated second power cord operationally engaged with the second riser side;

- a first end of the elongated third power cord operationally engaged with the second power cord cam of the first cam set, and
- a second end of the elongated third power cord opposite the first end of the elongated third power cord operationally engaged with the second power cord cam of the second cam set;
- and
- an elongated bowstring having
- a first end of the elongated bowstring operationally engaged with the bowstring cam of the first cam set, and
- a second end of the elongated bowstring opposite the first end of the elongated bowstring operationally engaged with the bowstring cam of the second cam set;
- and
- wherein
- the bow has a top side facing in a top direction,
- the bowstring cam of the first cam set has a top side facing in a top direction that is the same as the top direction of the bow, and
- the bowstring cam of the second cam set has a top side facing in a top direction that is the same as the top direction of the bow and has a bottom side opposite the top side.
