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.

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 string guide for a bow including first and second cams are mounted to first and second bow limbs, respectively. Each of the cams includes a string guide journal, an upper power cable take-up journal, and a lower power cable take-up journal. The draw string is arranged in a reverse draw configuration. The upper and lower power cables are received in each of the respective upper and lower power cable take-up journals and are displaced away from the respective draw string journals as the bow is drawn from the released configuration to the drawn configuration. In one embodiment, the upper and lower power cable take-up journals are helical in configuration. As a result of this configuration the cams can rotate more than 270 degrees, and preferably more than 300 degrees, as the bow is drawn from the released configuration to the drawn configuration.

摘要： A crossbow including first and second flexible limbs are attached to a center rail. A draw string extends across the center rail that translates between a released configuration and a drawn configuration. A string carrier including a catch is movable between a closed position that engages the draw string and an open position that releases the draw string. The string carrier slides along the center rail to engage with the draw string in the released configuration and slides to a retracted position that locates the draw string in the drawn configuration. A retaining mechanism retains the string carrier in the retracted position and the draw string in the drawn configuration. A trigger moves the catch from the closed position to the open position to fire the crossbow when the string carrier is in the retracted position.

摘要： A string control assembly for a crossbow having a catch, a sear, a dry fire lockout and a trigger assembly. Engaging the draw string with the catch when in the open position after firing the crossbow generates a force that pushes the catch from the open position to the closed position and automatically (i) couples the sear with the catch at the interface to retain the catch in the closed position, and (ii) moves the dry fire lockout to the lockout position to block the sear from moving to the de-cocked position. In one embodiment, engaging the draw string with the catch automatically moves the safety to the safe position coupled with the sear to retain the sear in the cocked position.
