发明名称 Dart and dartboard therefor
摘要 A dart game is described which consists essentially of a dart comprising (a) a cone-shaped nose part having a base and a rounded tip, (b) a tail part bearing fins, (c) a stem part connecting the tail part with the base of the nose part, and (d) a ballast member intermediate the tail part and the nose part and being adaptable for being shifted during flight from a position adjacent the tail part toward said nose part, and a dartboard. A preferred dartboard comprises ( alpha ) a base part having a front face, ( beta ) a layer of dart-holding projections on the front face, each of the projections protruding substantially at right angle from the front face and being elastically flexible and deflectable by the nose part of the dart when the latter penetrates into the layer, and ( gamma ) engagement means on both the dart and the projections, the engagement means of the dart being adapted for engaging the engagement means of at least two of the projections when the dart has penetrated the layer and the blunt tip of the nose part is at or near the front face.
