  • Patent number: 4141557
    Abstract: Disclosed is a segmented target useful particularly as a simulated golf green. The target is made up of multiple parallel strands of wire supported above the ground and running cross wise to each other, thus defining a number of segmented areas. A netting lies over the wire strands and segmented areas. In each segmented area the netting extends downwardly in a conical shape that terminates in a ring structure fitted with an electrical switch for indicating at a remote location the passage of a golf ball through the ring structure.

  • Patent number: 3990708
    Abstract: An indoor/outdoor recreational golf facility having a plurality of indoor putting greens, an outdoor pitching green, a plurality of mechanized range greens simulating the conventional greens, and a plurality of driving tees. The mechanized range green has a ball retrieval system and electrically relays to a display register, situated adjacent the driving tee, the location of where the ball hit the green relative to a flagstick. The mechanized range green is comprised of a mesh-like netting material segmented into squares. Each square net is supported in a raised position by structural posts and guide wires, and each net slopes inward to a center position. The ball hitting a net rolls through a hole in the center and actuates the electrical position switch, and thereafter automatically returns to a retrieval area. The overall mechanized green is raised above the ground level with an artificial turf sloping to the ground simulating the approach apron.
