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.

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 reduced length crossbow with a trigger located near a midpoint of the crossbow and a small included angle of the draw string when in the drawing configuration that creates a space between the draw string and the user's face. The included angle of the draw string when in the drawing configuration may be less than about 25 degrees. The trigger is typically located proximate the midpoint within about 10% of the overall length of the crossbow.

摘要： A cocking system for a crossbow. A string carrier slides along the center rail during movement with the draw string in the released configuration to a retracted position that locates the draw string in the drawn configuration. A trigger is positioned to move the catch from the closed position and the open position to fire the crossbow when the string carrier is in the retracted position. At least one cocking rope is configured to engage with the string carrier to retract the string carrier and the draw string to the drawn configuration. A retaining mechanism retains the string carrier in the retracted position and the draw string in the drawn configuration independent of the cocking ropes.
