Definitions

  • This invention relates to the game of golf and is concerned with a device to assist golfers in striking the ball correctly.
  • the stance of the player and the manner in which the player approaches the ball are of the utmost importance.
  • the ball will not necessarily move in the required direction and at the required speed because of irregularities in the surface of the green over which the ball has to travel.
  • GB-A-2224450 discloses a putting practice device having a base made of styrofoam or some other relatively light material. The putting surface is covered by a fabric covering such as an outdoor carpet with the fibres bound to the base.
  • the putting practice unit of GB-A-2121297 has a putting surface made of two sections which can be pivoted relative to one another. The putting unit has a base made of expanded polystyrene which is covered by a nylon-based artificial grass surface.
  • the putting system of US-A- 5445381 has aputting green and base made of extruded aluminium planks. The putting system has four corner adjusters which can be used to level the surface or arranged such that the putting surface has some "break". When the adjusters are arranged at different heights the weight of the system twists the aluminium planks.
  • a practice putting green comprises a planar member having a smooth surface, said member being formed of slate or like material having a surface of similar smoothness to slate, a simulated grass layer superposed on said smooth surface, an aperture extending through said layer to receive the ball, and a means of supporting the planar member so that said surface is horizontal.
  • the aperture is entirely surrounded by the simulated grass layer.
  • the aperture is located on the central longitudinal axis of the planar member. In preferred embodiments, the aperture is located off-axis with respect to the central longitudinal axis of the planar member.
  • the average surface smoothness is taken to be the range of heights between all of the points on the surface of a material.
  • the average surface smoothness of the planar member is between 0 ⁇ m and 2000 ⁇ m. In other embodiments, the average surface smoothness of the planar member is between 0 ⁇ m and 1500 ⁇ m. Conveniently, the average surface smoothness of the planar member is between 0 ⁇ m and 1000 ⁇ m. In preferred embodiments, the average surface smoothness of the planar member is between 0 ⁇ m and 500 ⁇ m.
  • the planar member is particularly preferred for the planar member to be formed of slate because it has a sufficiently smooth surface and is relatively inexpensive. Slate can be machined relatively easily to have a surface smooth enough to ensure the true running of a golf ball putted across a surface made of it. The price of slate and the small amount of machining required to produce a smooth surface make slate a cost-effective option for a putting surface. However, other materials of similar surface smoothness, such as marble, can be used.
  • the planar member is made from a material having a coefficient of thermal expansion of around 1 x 10 "6 per °C to 50 x 10 "6 per °C.
  • the planar member is made from a material having a coefficient of thermal expansion of around 5 x 10 "6 per °C to 25 x 10 "6 per °C.
  • the planar member may be made from a material having a coefficient of thermal expansion of around 8 x 10 "6 per °C to 15 x 10 " ⁇ per °C.
  • the planar member is made from a material having a coefficient of thermal expansion of around 9 x 10 "6 per ° C to 11 x 10 "6 per ° C.
  • a planar member made from a material having a relatively low coefficient of thermal expansion will not deform under extremes of temperature. Thus, the surface of the planar member will not deform or warp appreciably even under extremes of temperature. This enables a putting green incorporating a planar member made of such a material to be used both indoors and outdoors in all types of climate.
  • the planar member may be made from a material having a density of substantially 2500 to 3000 kg/m 3 .
  • the planar member is made from a material having a density of substantially 2600 to 2900 kg/m 3 .
  • the planar member may be made from a material having a tensile strength of around 50 to 70 Nmm “2 .
  • the planar member may be made from a material having a compressive strength of around 180 to 250 Nmm “2 .
  • the planar member is made from a material having a modulus of around 50 to 150 Nmm “2 .
  • the planar member has a thickness of between 0.5 and 10 cm.
  • the planar member has a thickness of between 1 cm and 5 cm.
  • the planar member has a thickness of substantially 2 cm. The thicker the planar member is the greater is the tendency for the member to stay flat.
  • the planar member has a longitudinal length of between 0.5 m and 2.0 m. Most preferably, the planar member has a longitudinal length of substantially 1.0 m. In preferred embodiments, the planar member has a lateral width of between 20 cm and 50 cm. Preferably, the planar member has a lateral width of around 30 cm.
  • the simulated grass may be in the form of a backing material to which fibres are attached so that they are generally perpendicular to the backing material.
  • the fibres are preferably formed of synthetic plastics material and are flexible rather than rigid so as not to interfere with the true running of the ball.
  • An example of simulated grass of this type is a synthetic sports surface known as Match- Winner and available from Play - Rite Ltd. of Liversedge, West Yorkshire, UK. This is a vertical loop, structured, scrim reinforced needle punch material having a backing thickness of 4.0mm and a polypropylene pile of thickness 11.0 mm. Another material which may be used is that known under the Trade Mark Astroturf.
  • the simulated grass may be in the form of a bowling carpet.
  • a suitable material of this type is 7.00 mm thick felt available from Le Feutre S.A. in France. This includes a backing material formed of a wool/polyester/viscose mixture and a playing surface formed of wool.
  • green baize such as is used on billiard tables may be used as the simulated grass.
  • the speed of the ball will generally be much greater than when rolling over the turf of a natural putting green and this is less desirable.
  • the planar member is mounted in a frame of, for example, a metal such as aluminium and the means for supporting the member is in the form of feet depending from the frame and of adjustable length. '
  • the practice putting green is associated with a platform having an upper surface substantially coplanar with the surface of the planar member and on which the player can stand. It is preferred that the platform should not be attached to the practice putting green so that any movement of the platform as the player stops on and off it is not transmitted to the planar member and hence the horizontal disposition of the planar member is not disturbed.
  • the player In use of the practice putting green, the player stands adjacent to one end of the green, preferably on the standing platform if provided, places a golf ball on the green and hits the ball towards the aperture adopting what he/she believes to be the appropriate stance and approach. Because of the smoothness of the planar member, the ball will run true and, if struck correctly, will enter the aperture. Thus the player instantly knows whether or not his/her stance and approach was correct and, if they are not, and consequently the ball has not entered the aperture, the player can try again with an altered stance and/or approach.

  • the player stands on the platform 20, places a golf ball on the practice putting green in front of him/her and hits the ball towards the cup 10 after having adopted what he/she believes to be the appropriate stance and approach. Since the surface of the planar member 2 is completely smooth and horizontal, there is no interference with the run of the ball. Thus, if the ball fails to enter the cup 10, the reason for this is entirely because of the stance and approach of the player. The player can therefore modify his/her stance and/or approach and try again until he/she can consistently put the ball in the cup.
