Abstract: A crossbow having an energy storage system configured for storing energy when a bowstring is cocked at full-draw and releasing at least a portion of the stored energy when a trigger is pulled releasing the bowstring. The stored energy is defined by an area under a power-curve or draw-curve of the crossbow. The power-curve is defined by the force required to draw the bowstring from an un-cocked position to the cocked position. Between the un-cocked position and an intermediate position, the force required to draw the bowstring is substantially proportional to the draw distance. Between the intermediate position and the cocked position, the force required to draw the bowstring is substantially constant. When the cocked bowstring is released, at least a portion of the stored energy is transferred in the form of kinetic energy of an arrow or bolt nocked on the cocked bowstring.

Abstract: A crossbow includes a riser. The crossbow includes a first limb and a second limb. The first limb includes a first end and a second end. The second limb includes a first end and a second end. The first end of the first limb and the first end of the second limb are coupled to the riser. A first wheel is rotatably coupled to the first limb proximate the second end thereof. A second wheel is rotatably coupled to the second limb proximate the second end thereof. The crossbow includes a first power cord that includes a first end coupled to the riser and a second end coupled to the first wheel. The crossbow includes a second power cord a first end coupled to the riser and a second end coupled to the first wheel. The crossbow includes a bowstring. The crossbow includes an efficiency of at least 80%.

Abstract: An energy storage system for a bow, the system defined at least in part by a riser, a first and second limb each having a first end coupled to the riser, a first and second wheel disposed at a second end of respective first and second limbs, a first and second power cord each having a first end coupled to the riser and a second end coupled to respective first and second wheels, and a string extending between and coupled to the first and second wheels.

Abstract: A firing system for a crossbow includes a bowstring carrier and a trigger assembly. The bowstring carrier includes a sear and a catch. The trigger assembly includes a trigger and a trigger roller. An embodiment of the firing system includes a bowstring carrier, a trigger assembly, and a dry-fire inhibitor. Another embodiment of the firing system includes a bowstring carrier, a trigger assembly, and a safety. Yet another embodiment of the firing system includes a bowstring carrier, a trigger assembly, a dry-fire inhibitor, a safety, and a safety reset.

Abstract: A lighted nock may include an arrow nock, LED/battery assembly, and an end cap. The end cap may be engaged with the inner diameter of a portion of an arrow shaft, and a portion of the LED/battery assembly may be engaged with the end cap. An arrow nock may be selectively positioned over a portion of the LED/battery assembly and/or engaged with the inner diameter of a portion of the arrow shaft such that the user may determine when the LED in the lighted nock is illuminated and when the LED is not illuminated.
