发明名称 SHOCK ABSORBING HORSESHOE PIT
摘要 A horseshoe pitching court including a fixture which is embedded at a predetermined location in a pad below the playing surface of the court. A base is loosely held captive by the fixture and has a first bottom horizontal surface and a second bottom surface inclined with respect to the first surface with an edge of the base common to both surfaces extending transverse to the longitudinal direction of the court. The base is thus rockable on this edge in the longitudinal direction of the court between a first position in which the first surface of the bottom of the base engages the fixture and a second position in which the second surface of the bottom of the base engages the fixture, the base being gravity biased toward its first position. A stake is held by the base and it extends generally vertically from the base above the surface of the court whereby a pitched horseshoe hitting the stake causes the base to rock from its first position to its second position.
