Abstract
A multiple-shot crossbow includes a mainframe, a riser, upper and lower bow limbs and bowstrings, and a trigger mechanism. The mainframe includes upper and lower rails, each for supporting and guiding a corresponding bolt. The riser includes a passage for accommodating loading and launching a bolt. The bow limbs are attached to the riser and the bowstrings are attached to the bow limbs. Each bowstring is arranged independently to be drawn from a brace position to a drawn position and then return to the brace position while launching a bolt positioned on the corresponding rail. The lower bowstring is movable within a longitudinal slot between the upper and lower rails. The trigger mechanism is attached to a rear end of the mainframe and includes upper and lower trigger portions, each retaining a corresponding drawn bowstring and then releasing it upon actuation by a user.
