  • Patent number: 4875685
    Abstract: A golf practice apparatus simulates the response of natural turf to the impact of a golf club head during a conventional golf club swing. The apparatus includes a platform for the golfer to stand on, a main frame connected to the platform adjacent thereto, and an inner frame carrying an upper surface mounted within the main frame and connected thereto such that the rearward end of the inner frame can translate forwardly and the forward end of the inner frame can translate initially forwardly and thence downwardly in a generally arcuate path when the upper surface is impacted by the golf club head. The platform is configured as a hinged box which can be folded together to form a closed case in which the main frame and associated components can be stored. A ball storage ramp including a golf club head actuable ball filter is removably attachable to the main frame.
