Abstract
A crossbow that includes a barrel having a pair of limbs and a bowstring cable that extends between the limbs, a trigger mechanism for selectively capturing and releasing the bowstring cable against flexure of the limbs, and a guide for supporting a bolt on the barrel when the cable is captured by the trigger mechanism. The trigger mechanism in the preferred embodiment of the invention includes a latch mounted for pivoting between a closed position in which the latch captures the cable and an open position for releasing the cable. A latch release arm is mounted adjacent to and in opposed engagement with the latch. The upper surface of the latch release arm engages the latch for releasably holding the latch in both the open and closed positions. A trigger linkage operatively couples a trigger to the latch release arm to release the latch release arm from holding the latch in the closed position, so that force of the cable against the latch pivots the latch and the latch release arm from the closed to the open positions so as to release the cable and fire the bow.
