A crossbow includes an elongated frame coupled to a riser at a first end thereof and attached to an upper housing at its second end generally above the trigger region. The riser supports a pair of flexible limbs, and a bowstring extends between such limbs. A bowstring retractor is provided within the upper housing and includes a rope spool used to wind a retractor rope for retracting the bowstring. First and second spool gears surround the rope spool for rotation therewith. A spur gear mounted on a drive axle engages one of the spool gears, and a crank can be engaged with the drive axle. A pawl engages the other spool gear to prevent unintentional unwinding of the retractor rope from the rope spool. A pawl release member disengages the pawl from its associated spool gear. Drawing the bowstring beyond its full draw position also disengages the pawl.

Some embodiments adapt a mobile smart device such as an iPhone with a range sensor to be a high resolution rangefinder with a touch screen, GPS, and video analysis capabilities.

Improved compound bows which are smaller, more compact, lighter, and more easily handled and serviced than compound bows of conventional construction but are nevertheless capable of propelling an arrow at an equal or higher velocity and with comparable or greater accuracy than a conventional bow. The improved bows are quieter than those of conventional construction and less apt to snag on brush or other obstacles. They have a rigid riser with ends to which string cams are rotatably mounted and cam-associated power units mounted to and towards the ends of the riser. Each power unit has a component which is elastically deformed to store potential energy as the bow is drawn and a power cable connecting the power storing component to the associated string cam. A bow string extends between and is connected at its opposite ends to the string cams. As the bow is drawn, the string cams are rotated in counter directions, pulling on the power unit cables and thereby elastically deforming and storing potential energy in the power unit components. When the bow string is subsequently released, the elastically deformable power unit components restore to rest configurations, this converting the stored potential energy to arrow propelling kinetic energy. A timing cable arrangement insures that the cams are synchronized to rotate in unison, avoiding the unwanted nock travel that might otherwise occur; and the power units have an adjustment feature which allows the force required to fully draw the bow to be changed.

The present invention relates generally to crossbow bowstring drawing mechanisms, also called cocking mechanisms in the art. More particularly, the present invention relates to a crossbow bowstring drawing mechanism that is integrated into a crossbow. The mechanism primarily consists of a pneumatically actuated piston and cylinder assembly, a compressed gas dispenser, and a string pick up arm. An after-the-fact bolt-on kit is also intended to be within the scope of this application allowing retrofit to existing bows not currently outfitted with this cocking feature. The bowstring cocking mechanism may utilize an internal power source such as compressed carbon dioxide (CO₂) cartridge, or a plurality of cartridges to actuate the pneumatics that are part of the cocking mechanism on demand. Such actuation draws a bowstring from the un-cocked position to the cocked position. Likewise, such actuation will equally allow a controlled dry-fire, allowing the bowstring to be released from the cocked position to the un-cocked position; the pneumatics acting as a system damper, preventing damage to the bow limbs.
