Abstract
A dart game target having a base on which is assembled a plurality of individual, relatively movable target members separated from one another by a frame having thin ribs interposed between adjacent members. The target members are yieldably biased in a direction away from the base. Movement of the members in a direction away from the base is limited by laterally extending projections carried by the target members which underlie the inner surfaces of the ribs. The arrangement is such that no part of any rib overlies any exposed part of any target member. Warping of the frame or of the base is compensated for by protrusions on selected ones of the ribs which extend in a direction toward the base.
