摘要： A projectile launcher includes a frame that has a front and rear end. A projectile is configured to be propelled from the front end of the frame and the projectile is movable along a projectile axis during firing and arming of the projectile launcher. The projectile launcher includes a latch movable between the rear end of the frame and the front end of the frame along a travel axis and is attached to a crank mechanism via a tether. The projectile launcher also includes flexible limbs that drive a drawstring of the projectile launcher during the firing of the projectile launcher.

摘要： A crossbow including a center rail including a rail body and a riser, a first flexible limb coupled to the riser, a second flexible limb coupled to the riser, and a first cam mounted to the first flexible limb and rotatable around a first cam axis. The first cam including a first draw string journal defining a first draw string plane of rotation perpendicular to the first cam axis, and a first power cable take-up journal extending in a direction perpendicular to the first draw string plane of rotation. The crossbow further including a second cam mounted to the second flexible limb and rotatable around a second cam axis. The second cam including a second draw string journal defining a second plane of rotation perpendicular to the second cam axis, and a second power cable take-up journal extending in a direction perpendicular to the second draw string plane of rotation.

摘要： A high impact strength lighted nock assembly for an arrow that is activated when the arrow is fired with a bowstring. The lighted nock assembly includes a nock molded from a high impact strength, transparent polymeric material containing at least 10% by weight reinforcing fibers. The nock includes a head configured to engage with the bowstring and a shank configured to couple with a rear end of the arrow. The shank includes a recess extending in a distal end of the shank toward the head. A light assembly including a light emitting device is located in the recess in the shank that is electrically coupled to a battery. A switch is electrically coupled to the light emitting device and the battery that is triggered when the arrow is tired to activate the light emitting device.

摘要： A crossbow is configured to shoot a projectile. The crossbow includes a frame having a stock positioned at a rear end, the frame defining a horizontal projectile plane at a top side in which a projectile axis is positioned. The projectile moves within the horizontal projectile plane and along the projectile axis during firing and arming of the crossbow, and the projectile is fired from a front end of the frame. The crossbow further includes a drawstring hub connectable to ends of a drawstring. Rotation of the drawstring hub in at least one direction is powered, such as by a force applied by flexed limbs. The crossbow further includes drawstring guides attached to the frame for guiding the drawstring across the projectile axis between the ends of the drawstring. The first and second drawstring guides each include a pulley wheel, wherein the drawstring is guided at least partially around each pulley wheel. A further aspect is a crossbow having a frame comprised of a first frame portion and a second frame portion that are detachably coupled to one another via a fastening mechanism.

摘要： 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.

摘要： A high impact strength nock assembly that couples with, and decouples from, a bushing mounted in an arrow. The forces applied to the nock during launch are translated to the arrow through the bushing, greatly extending arrow life. For lighted nock applications, the nock translates within the bushing during launch to activate the light. A battery stop is coupled to the battery and releasably coupled within the center opening of the bushing that resists longitudinal translation of the battery relative to the bushing. Consequently, the light can be deactivated without removing the lighted nock assembly from the bushing. The entire lighted nock assembly is removable from the bushing for maintenance and replacement.

摘要： A torque control system for cocking a crossbow. A cocking mechanism includes a rotating member mounted to the center rail and coupled to a flexible tension member attached to a string carrier. A cocking handle is configured to engage with the rotating member to cock the crossbow. A torque control mechanism limits output torque applied to the rotating member such that rotating the cocking handle after the string carrier is in the retracted position does not move the draw string past the drawn configuration.
