  • Patent number: 5388840
    Abstract: An improved dart flight with a stepped configuration on its leading and trailing edges is provided. The dart flight of the present invention enables a player to closely group darts with accuracy without unwanted deflection. The dart flight of the present invention includes a stepped configuration on the leading and trailing edges of both the horizontal and vertical vane components of the dart flight. When an incoming dart approaches a target in close proximity to a stationary dart already in the target, the leading stepped edge of the incoming dart communicates with the trailing stepped edge of the stationary dart to urge the dart flight on the incoming dart to be ejected from the shaft of the incoming dart. Since the dart flight is ejected, it cannot ride on the dart flight of the stationary dart to cause deflection and alteration of flight path. As a result, dart throwing accuracy can be maintained in close dart groupings.
