发明名称 Dart board apparatus with independently supported double bull segment
摘要 A dart board apparatus including a housing having a spider located therein. The spider is generally circular in shape and has a series of circumferentially and radially extending ribs which define a plurality of target segment openings, and a circumferential center rib which defines a center opening. A plurality of target segments are slidably disposed in the target segment openings. An annular outer bull segment, having a target surface with a center opening, and a generally tubular sidewall with at least two slots therethrough, is also provided. The outer bull is slidably disposed for movement within the center opening in the circumferential center rib. An inner bull segment is slidably disposed within the center opening in the outer bull segment. The inner bull segment includes at least two spokes, in an aligned position with the slots in the outer bull segment sidewall. Each spoke includes a first end connected to the inner bull, and a second end in slidable contact with the circumferential center rib so that the inner bull segment may slide independently of movement of the outer bull segment. At least one sensor is associated with each target segment, the outer bull segment and the inner bull segment.
