  • Patent number: 11768051
    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.

  • Patent number: 11015892
    Abstract: An anti-dry-fire mechanism for a crossbow includes a slotted mainframe and a movable trigger subassembly engaged with the slot for bidirectional movement between brace and drawn positions. The movable subassembly includes a bowstring latch forward of a bowstring catch and biased toward a bolt-absent position in which the bowstring latch obstructs forward movement of the bowstring past the bowstring latch; in its bolt-present position the bowstring latch permits such movement. With the movable subassembly in the drawn position, a bolt loaded onto the mainframe holds the bowstring latch in its bolt-present position against its bias; with the movable subassembly in the drawn position and no bolt loaded, the bowstring latch is held in its bolt-absent position by its bias. With the movable subassembly in the brace position, engagement of the mainframe and bowstring latch holds the bowstring latch in its bolt-present position against its bias.
