摘要: A crossbow de-cocking method may include the step of providing a trigger mechanism, a trigger latch mechanism and a winch assembly. A first input to the winch assembly may move a trigger latch to disengage the trigger mechanism. A second input to the trigger latch may move a crossbow bowstring from a cocked position to an un-cocked position.

摘要: A crossbow may include a main beam, a riser with a U-shaped opening, a pair of bow limbs and a bowstring. The riser may have limb attachment surfaces that are separated such that a minimum distance between them is at least as wide as a user's foot but not greater than about 5 inches. The riser may have a U-shaped opening that is designed to receive a user's foot.

摘要: A crossbow de-cock mechanism may include a de-cock activator that is selectively movable from a first de-cock activator position that prevents de-cocking of a crossbow into a second de-cock activator position that permits de-cocking of the crossbow.

摘要: A method of constructing a crossbow may include the steps of: supporting the riser to the main beam; supporting a pair of bow limbs to the ends of the riser; separating the bow limbs such that a minimum distance between them is not greater than about 5 inches; supporting the bowstring to the bow limbs; and providing at least a portion of the opening in the riser to be as wide as a user's foot and to extend between the bow limb.

摘要: A mid-limb cam crossbow system may comprise an elongated beam; a bow assembly engaged with the beam and having a pair of limbs; the pair of limbs being a first limb and a second limb, wherein the first limb has a proximate end and a distal end offset from the proximate end by a length L1, and the second limb has a proximate end and a distal end offset from the proximate end by a length L2. A first cam may be engaged with the first limb at a first cam mount point offset from the proximate end of the first limb by a length between (0.15)L1 and (0.75)L1. A second cam may be engaged with the second limb at a second cam mount point offset from the proximate end of the second limb by a length between (0.15)L2 and (0.75)L2.

摘要: Provided is a string suppressor for a crossbow comprising a first suppressor axis; a first suppressor plane containing the first suppressor axis; an elastomeric pad elongated along the first suppressor axis to define a first pad end, and a second pad end opposite the first pad end along the first suppressor axis; wherein the first pad end has a feature adapted for engagement with a crossbow riser; and wherein the second pad end has a string groove formed therein, the string groove being coextensive with the first suppressor plane, and has a cam groove formed therein, the cam groove being coextensive with the first suppressor plane, the cam groove being wide enough to provide a clearance fit with an associated cam.

摘要: Provided is a bow assembly comprising a main beam elongated in a first direction to define a distal end, and a proximal end, wherein the distal end has a distal end facing surface from which extend, an upper member, and a lower member having a first set of threads thereon; and a riser having a proximate facing surface, an upper groove dimensioned to engage the upper member, and a lower opening through hole dimensioned to engage the lower member; a threaded fastener adapted to threadedly engaged the first set of threads; and wherein the riser is assembled with the main beam and the threaded fastener such that the upper member is inserted within the upper groove, the lower member is inserted within the lower opening, the distal end facing surface faces the proximate facing surface, and the threaded fastener is threadedly engaged with the first set of threads.

摘要: Provided is a crossbow safety system comprising a crossbow, optic fence, and interlock. The crossbow may have a bowstring operable between a cocked and an uncocked position, the cocked position and the uncocked position defining between them a bowstring plane, and a trigger assembly adapted to selectably retain the bowstring in the cocked position. The optic fence may be adapted to detect an obstruction in a safety plane coincident with the bowstring plane or offset below the bowstring plane by some offset distance. The optic fence may have an infrared emitter adapted to output IR radiation, and a photodiode adapted to sense the output IR radiation from the infrared emitter. The interlock may be operationally engaged with the optic fence and the trigger assembly. The interlock may be adapted to lock the trigger assembly from releasing the bowstring if the optic fence detects an obstruction in the safety plane.
