Abstract
Abstract A double bullseye for a dart game which can be electronically scored when hit by a dart wherein the outer bullseye comprises a concentric moveable segment and the inner bullseye comprises a cylindrical member received in a central guide opening of the outer segment and wherein the inner segment is formed with a shoulder which limits the outward motion of the inner bullseye. Both the inner and the outer bullseyes are formed with feet portions which are engageable with electronic pressure sensitive switches so as to record hits by a dart in the respective segments.

A target for an electronic dart game wherein said target is formed of a plurality of radially extending ribs and concentric circular ribs to divide the target into a plurality of scoring segments, a double bullseye scoring means mounted within the inner concentric circular rib and comprising an outer annular target portion moveably mounted in said inner concentric circular rib, an inner generally cylindrical target portion mounted withn said outer annular portion and moveably mounted relative to said inner concentric circular rib, and switch means with a plurality of switch areas mounted to said target and actuated by said outer annular target portion and said inner cylindrical target portion when they are engaged by a dart so as to separately score hits by darts, wherein said outer annular target portion is non-rotatably mounted relative to said inner concentric circular rib, wherein said outer annular target portion is formed with a longitudinal key way and said inner concentric circular rib is formed with an extension which is receivable within said key way to prevent rotation of said outer circular target portion, wherein said outer annular target portion is formed with at least one extending foot which is engageable with a switch area of said switch means when said outer annular target portion is engaged by a dart to score an outer bullseye score, wherein said inner cylindrical target portion has at least one extending foot which is engageable with a switch area of said switch means when said inner cylindrical target portion is engaged by a dart to score an inner bullseye score, wherein said inner cylindrical target portion is formed with a first target portion which extends through the central opening of said outer annular target portion and a shoulder target portion which is larger in diameter than said first target portion which cannot pass through the central opening of said outer annular target portion, and wherein said outer annular target portion can move longitudinally relative to said inner cylindrical target portion to score an outer bullseye score without causing said inner cylindrical target portion to score an inner bullseye score.
