Definitions

  • a golf practice platform is divided into two sections one of which is stationary, and the other of which is mounted to tilt slightly as the golfers weight shifts from one foot to the other in order to indicate the instant when the shift occurs.
  • Each section has an artificial turf surface and the turf surface of the stationary section from which the ball is driven is laid above a pad of cellular elastomeric material to simulate actual playing conditions.
  • the entire platform may be tilted in various directions to simulate uphill, downhill and sidehill lies.
  • One of the important factors in a proper swing is ability to shift ones weight from one foot to another at the proper mo ment, and the ability to make the shift consistently, time after time.
  • the weight of the body is usually distributed evenly between the right foot and the left foot.
  • the weight must be shifted preponderantly to the right foot.
  • the weight must be shifted preponderantly to the left foot.
  • the difficulty is for the golfer to known exactly when his weight has shifted and to know whether it has shifted before or after it should have been shifted.
  • FIG. 1 is a top plan view of the platform.
  • FIG. 2 is an enlarged section on the line 22 of FIG. 1.
  • FIG. 3 is an enlarged section on the line 3-3 of FIG. 2.
  • FIG. 4 is an enlarged detail view of one corner of the platform, partly in section.
  • FIG. 5 is a section on the line 5-5 of FIG. 2.
  • FIG. 6 is a side elevation illustrating the tilting of the entire platform to simulate hilly conditions.
  • the platform comprises a rectangular frame 1 fabricated from any suitable structural members such as steel angle irons.
  • the vertical flanges 2 of the angle irons form the outside periphery of the frame and the horizontal flanges 3 extend inwardly therefrom.
  • the frame is supported on adjustable legs 4, one of which is located at each corner of the frame.
  • the frame is divided into two separate platform sections 5 and 6 by a transverse frame member 7 which may also be a steel angle iron, welded or otherwise secured to the side frame members.
  • Section 5 of the platform is the ball supporting section. It comprises a flat rectangular platform panel 8, preferably of plywood, having a rectangular opening 9 formed therein. Located below the member 8 is a basket formed of crossed steel strips 10 and 11 which extend transversely and longitudinally of the platform and are bent upwardly and outwardly near their ends to form flanges 12 which rest on the frame flanges 3 to support the basket. The member 8 rests on the flanges l2. Mounted within the basket below the opening 9 is a pad 15 of cellular elastomeric material such as cellular rubber or polyurethane. The upper surfaces of pad 15 and member 8 are covered with a layer of artificial turf 16 such as that now available commercially from Monsanto Co. under the name Astroturf.
  • the artificial turf is adhesively secured to the member 8 and the pad 15, and the turf above the pad is flush with that above the member 8.
  • the tufted surface of the artificial turf simulates ordinary grass turf and supports a golf ball in much the same manner.
  • the elastomeric pad 15 permits the artificial turf to be depressed when struck by the club head practicing iron" shots to simulate the feel oftaking a divot.
  • the pad 15 may be removed from the basket and a pan filled with sand may be inserted to simulate conditions when a golfer finds his ball in a sand trap.
  • Section 6 of the platform is the tilting section on which the golfer stands. It comprises a rectangular platform member 17 covered with a layer of artificial turf l8 adhered to the upper surface thereof as previously described. The layer 18 is flush with the layers of turf which cover the section 5.
  • This section of the platform is mounted to tilt on the frame on an axis which is perpendicular to the end edges of the frame 1, and equally spaced from the side edges thereof. It is, therefore, perpendicular to a line between the golfer's feet and is spaced at substantially equal distances from each foot when the feet are properly placed for driving.
  • the member 17 is secured to a supporting member 20 by straps 21.
  • the supporting member has a shaft 22 secured thereto and extending longitudinally beyond the ends thereof into hole 23 in the vertical flange 2 of the frame and hole 24 in the transverse frame member 7, which said holes serve as bearings to permit the shaft and platform to tilt.
  • the platform section 6 tilts in one direction or the other.
  • the tilting movement of the platform section 6 is restrained by engagement of the member 17 with one or the other of the horizontal flanges 3 of the frame acting as a stop.
  • the amplitude of the tilting movement should be small and inch should not exceed three-eighths inch as measured between the flanges 3 and the edges of the platform member 17. This slight tilting movement is sufficient to give the golfer an indication of the exact moment when his weight is shifted from one foot to the other, but is insufficient to disturb his balance or to otherwise interfere with his swing. It is important also that the tilting movement be limited to movement about a single axis, for movement in any other direction would tend to give the golfer a false indication.
  • an adjustable leg 4 is mounted at each comer of the frame. As shown in FIG. 4 the legs 4 are threaded and they are screwed into threaded socket members 18 secured to the frame at each comer thereof. As shown in FIGS. 5 and 6, the provision of such adjustable legs permits the entire platform to be tilted in various directions to simulate an uphill lie, a downhill lie or a sidehill lie. Since the entire platform including both sections 5 and 6 is tilted by adjustment of the legs, the golfer receives the same indication of shift of weight regardless of the direction of tilt.
  • a golf practice platform comprising a rectangular frame, said frame having two sections, one of said sections being stationary and comprising a flat platform panel supported by said frame and having an opening therein, a basket mounted below said opening, a pad of cellular elastomeric material in said basket below said opening, a layer of artificial turf secured to the upper surface of said platform panel, a layer of artificial turf secured to the upper surface of said pad and flush with the layer on said panel, the other of said sections comprising a second flat platform panel, a layer of artificial turf secured to the upper surface of said panel, and means for mounting said second platfomi panel to tilt with respect to said frame on an axis which is perpendicular to the ends of the frame and equally spaced from the sides of the frame.
  • a golf practice platform as claimed in claim 1 in which said rectangular frame is provided with a supporting leg at each corner thereof, each of said legs being adjustable to raise or lower the frame so that the entire platform may be selectively tilted to simulate uphill, downhill or sidehill lies.
