A crossbow including first and second flexible limbs attached to a center rail. A first cam is mounted to the first bow limb and rotatable around a first axis. A draw string is received in string guide journals and is secured to first and second cams. The draw string unwinds from the string guide journals as it translates from a released configuration to a drawn configuration. Power cables are received in first and second power cable take-up journals on each of the first and second cams. As the crossbow is drawn from the released configuration to the drawn configuration the first and second power cables wrap onto the respective first and second power cable take-up journals and are displaced along the first and second axes away from the first and second planes of rotation of the first and second draw string journals.

An adjustable archery training bow assembly includes a single resistance element and an adjustment mechanism that can be actuated by a user to vary the tension level in the resistance element for training purposes. The training bow also includes a mount for receiving a mobile device, which allows the user to practice various augmented reality-archery training scenarios. The adjustable archery training bow is used to enhance the user's skills, such as his/her strength, stability, and accuracy to help deliver on-target an arrow fired from a real, non-training bow.

A crossbow including pulleys rotatably attached to a center rail of the crossbow. Power cables of the crossbow connect the limbs of the crossbow to the pulleys. The draw string is enclosed in a safety cover. The crossbow includes a cocking system that translates a string carrier along the center rail to cock and de-cock the crossbow.

The present invention relates to abrasion resistance of bowstring fibers with a coating containing Polytetrafluoroethylene (PTFE) particles to increases string life. The claimed coating lowers the coefficient of fiction of the bowstring reducing internal yarn on yarn abrasion, external abrasion and increases longevity.

A crossbow assembly uses an arrangement with two pairs of limbs, with one pair of opposing limbs on each side of the stock. The two limbs within each pair are arranged in opposition to each other in a vertical plane. The limb tips are each connected to an axle assembly with respective limb cables. The axle has a pair of axle pulleys at opposing ends. A bowstring has opposing ends connected to each axle pulley. The bowstring extends forward from each axle pulley and extends across the stock, passing between two bowstring pulleys. The middle of the bowstring forms the nock point.

The present disclosure provides an energy storage and relock mechanism for a power assisted bow comprising a charge cam and a relock lever. The charge cam may be configured to store potential energy by rotating in a first direction. The relock lever may be configured urge rotation of the charge cam in the first direction to lock potential energy in the power assisted bow.

A method of engaging an arrow with an anti-dry fire system on a crossbow and an arrow assembly for crossbow that engages the anti-dry fire system behind the draw string. Matched weight arrows having lighted and non-lighted nocks are also disclosed.

A method of micro adjusting cam timing on an archery bow includes separating filaments of a cable or bow string to form a split area and inserting an adjustment spacer into the split area. The adjustment spacer causes a length of a bow string or cable to be shortened. The split in the cable or bowstring requires moving the limbs toward each other to allow the filaments of a cable or bowstring to be separated for insertion of the adjustment spacer. However, the cable or bow string may be sold with a pre-inserted split holder to allow the adjustment spacer to be inserted into the bow string without the need for a bow press. The adjustment spacer includes a middle perimeter, which tapers outward in opposing directions to a larger retention perimeter. The split holder is preferably a thin disc with a plurality of notches formed around a perimeter thereof.
