ABSTRACT:
A snap-on dart flight that is readily attachable to a flight rotation shaft by the simple procedure of inserting the shaft mating portion into an internal axial cavity located within the flight. The axial flight cavity is comprised of a flight mating portion having one or more extension(s) and/or recess(es) which can be of any desired cross-sectional shape. e.g., rounded, v-shaped, cylindrical, etc., and is located along the flight central axis. The flight of this invention is comprised of a centrally located bushing tube having a plurality of vanes, usually four, equally spaced around said bushing tube. The vanes can be integral with the flight bushing tube or mounted on the outside surface thereof, e.g., using an adhesive. In accordance with a preferred embodiment of this invention, the flight is molded or otherwise formed in one piece to have the axial cavity described. Alternatively, a flight axial bore tube can be inserted within the flight bushing tube to define said cavity forward portion. Although the flight is preferably free to rotate 360 degrees around its central axis, it can be fixed in position, at the election of the user.
