Abstract
A crossbow (1) includes a frame (2) having at least a flexing element (3) and a bowstring (4) strung between opposite ends of the flexing element (3) positioned substantially perpendicular, under rest conditions, to the shooting axis of the crossbow. On the frame (2) is mounted a trigger block (8) provided with means for catching and releasing the bowstring. The trigger block (8) can be translated on a rectilinear path parallel to the longitudinal axis of the crossbow, in which in a first phase the trigger block advances towards the flexing element (3) until it automatically catches the bowstring (4), and in a second phase the trigger block (8) moves back until reaching a positioning of correct tensioning of the bowstring. The trigger block is actuated by electromechanical means shaped in such a way as to produce on the trigger block (8) a force that is substantially parallel to the shooting axis of the crossbow to carry out said first and second phase.
