Dart board assembly for an electronic dart game

A dart board assembly for use in an electronic dart game, said assembly comprising:

• a frame of integral plastic construction having an inner end, an outer end and an axis comprising a generally annular central wall defining a bull's-eye, a plurality of radial walls extending away from said central wall, and a circular wall, concentric with said central wall and spaced therefrom, each of said walls extending intermediate said ends and said circular wall and said radial walls defining, at least in part, a plurality of spaces;
• said central wall and said circular wall having side surfaces disposed toward said axis, and said radial walls each having a pair of side surfaces with a side surface of each radial wall facing a side surface of an adjacent radial wall, at least certain of said walls having an enlarged rib at said outer end forming a constricted outer throat for each of said spaces;
• a target segment of integral plastic construction disposed in each of said spaces including a target plate having a great plurality of closely spaced apertures for receiving the shaft of a dart, each said plate being shaped so that it engages the enlarged rib forming the throat of its space to prevent movement of said target segment through the throat, each of said target segments further comprising at least a pair of spaced legs extending from said target plate toward said inner end of said frame with each of said legs being engageable with at least two of the aforementioned walls, said target segments being open between said legs with each leg terminating in a small protuberance;
• and
• a switching matrix disposed adjacent said inner end of said frame and having contact means associated with each of said legs and aligned with the protuberance carried by the corresponding leg, each contact means comprising a pair of contacts biased to one of an open circuit condition and a closed circuit condition and adapted for movement to the other circuit condition due to force applied by the corresponding protuberance upon a dart striking the corresponding target segment.
