A crossbow includes an elongated frame coupled to a riser at a first end thereof. The riser supports a pair of flexible limbs, and a bowstring extends between such limbs. A movable bowstring release is used both to retract the bowstring into a drawn position, and to release the bowstring under the operation of a trigger assembly. The bowstring release is initially positioned near the bowstring at rest, and a bowstring hook is engaged therewith. A bowstring retractor includes a retractor rope secured to the bowstring release for retracting the bowstring. An upper housing is secured to the second end of the elongated frame, and supports a rope spool used to wind the retractor rope.

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. |
