Patent attributes
An anti-dry fire system for a crossbow including a catch moveable between a closed position that retains the draw string in a drawn configuration and an open position that releases the draw string to a released configuration position. A sear is moveable between a de-cocked position and a cocked position coupled with the catch at an interface to retain the catch in the closed position such that after firing the crossbow the sear is retained in the de-cocked position by the catch. A dry fire lockout is moveable between a disengaged position and a lockout position that blocks the sear from moving to the de-cocked position. The dry fire lockout includes a portion located behind the draw string that engages with the arrow to move the dry fire lockout to the disengaged position. This configuration precludes the use of the most common arrow nocks (flat, half-moon, etc.), reducing the risk that a non-approved arrow will be used in the crossbow.
