Abstract

A crossbow including a frame haying a projectile axis; a first flexible limb and a second flexible limb attached to the frame; a first cam attached haying a larger diameter portion, a smaller diameter portion, and a rotational axis substantially parallel to the projectile axis; a second cam haying a larger diameter portion, a smaller diameter portion, and a rotational axis substantially parallel to the projectile axis; a first pulley attached to the first flexible limb; a second pulley attached to the second flexible limb; a first power cable attached to the smaller diameter portion of the first cam and the first flexible limb; a second power cable attached to the smaller diameter portion of the second cam and the second flexible limb; and a drawstring attached to the larger diameter portion of the first cam and the larger diameter portion of the second cam.

Abstract

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.

Abstract

A projectile launcher includes a frame and a projectile moves within a horizontal projectile plane and along the projectile axis. The projectile is fired from a front end of the frame. The projectile launcher includes a first power group at a first frame side. The first power group includes a plurality of first power group drawstring pulleys. At least one of the plurality of first power group drawstring pulleys is attached to the frame. The projectile launcher further includes a second power group at a second frame side. The second power group includes a plurality of second power group drawstring pulleys. At least one of the plurality of second power group drawstring pulleys is attached to the frame. The drawstring is configured to be routed at least partially around the first and second power group drawstring pulleys.

Abstract

A projectile launcher includes a frame having a vertical grip and a forearm brace configured to stabilize the projectile launcher using a user's arm. The projectile launcher includes a drawstring hub rotatably mounted to the frame and rotatable in a first direction and a second direction. Movement of a drawstring away from the drawstring hub corresponds with rotation of the drawstring hub in the first direction and movement of the drawstring toward the drawstring hub corresponds with rotation of the drawstring hub in the second direction. The projectile launcher includes at least one flexible limb attached to at least one power cable. A power cable section of the drawstring hub, where the power cable is connected, has a let-off portion. The let-off portion has a first section having a first diameter and a second section having a second diameter and the first diameter is greater than the second diameter.

Abstract

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.
