SPECIFICATION A putting practice unit

This invention relates to a putting practice unit and in particular, although not exclusively, to a 5 putting practice unit for indoor use.

A known putting practice unit comprises a mat which is laid on a floor to enable the golfer to practice his putting. Most floors are flat and level and do not permit the golfer to practice puts which 10 are other than on a flat and level surface and does not allow variations in the putting surface. According to the present invention a putting practice unit includes a board and a number of board support means, the board having a putting 15 surface with an opening which in use, may receive a ball, the or each board support means being arranged to extend between the board and the floor surface, the board support means being adjustable whereby the orientation of the board 20 relative to the floor surface may be varied thereby varying the putting surface. With such a putting unit, the putting surface may be varied to allow puts to be made on a surface other than one which is flat and level, although of course, a 25 putting surface which is flat and level may be provided if required.

Preferably each board support means comprises an assembly including a board engaging member and a leg pivotally mounted on 30 the board engaging member. Pivotal adjustment of the leg provides a convenient way of altering the height of that part of the board with which the board engaging member engages.

Advantageously the board engaging members 35 comprises a channel shaped member arranged to receive the edge of the board. Thus the board engaging member may be readily attached and detached from the board. Advantageously the sides of the channel shaped member are flexed 40 away from each other when the channel shaped member receives the edge of the board. Thus the channel shaped member may be held in position on the board by the natural flexure of the sides of the channel shaped member. Preferably, the edge 45 of the board has indentations corresponding to the channel shaped member to facilitate attachment of the channel shaped member on to the board and provide an accurate location of the channel shaped member thereon. The board engaging 50 member and/or the leg may be moulded from plastics.

Advantageously the board may include at least two board sections. This facilitates storage of the unit. Preferably at least one channel shaped 55 member receives the edges of the two board sactions thus the channel shaped member can provide the necessary rigidity between the two board sections. Preferably the putting surface is provided by a flexible surface secured to and 60 connecting the board sections whereby, although the board includes at least two board sections, these can be folded together to provide a compact structure for storage whilst still enabling the unit to provide a continuous putting surface.

65 Advantageously the unit includes a platform of substantially the same thickness as the board which, in use, may be located adjacent to the board. The platform may be wedge shaped. Accordingly a person using the unit may stand at 70 the same height and inclination as the putting surface.

The board, board sections or platform may include expanded polystyrene blocks to provide a lightweight unit.

75 The putting surface may be provided by a flexible polypropylene mesh having attached thereto a nylon based artificial grass surface. The artificial grass surface can be brushed to alter the "nap" of the grass and may also be wetted to 80 simulate conditions likely to be found on a golf course.

The invention may be carried into practice in various ways but certain embodiments will now be described by way of example and with 85 reference to the accompanying drawings, in which:—

Figure 1 is a perspective view of a putting practice unit affording a downwardly sloping putting surface;

90 Figure 2 is a view similar to Figure 1 with an upwardly sloping putting surface;

Figure 3 is a partial view of a putting practice unit affording a downwardly sloping putting surface;

95 Figures 4A and 4B are perspective views showing how a board engaging member of a board support means is attached to the board of a putting practice unit;

Figure 5 is a perspective view of the central 100 section of the putting practice unit shown in Figures 1 and 2; and

Figure 6 is a perspective view of the putting practice unit showing two board sections in a partially collapsed position.

105 As shown in Figures 1 and 2, the putting practice unit comprises a board 10 with a putting surface 12. A person may stand on a platform 14, located adjacent to one end of the board 10, and put his ball along the putting surface 12 towards 110 an opening or hole 16 in the other end of the board 10.

A number of board support assemblies 18 engage the edges of the board 10 with a channel shaped member 20, each channel shaped member 115 having a leg 22 pivotally connected thereto. In Figure 1, the legs 22 of the assemblies 18 at the end of the board 10 adjacent to the platform 14 are orientated such that that end of the board lies clear of a floor surface 24. The legs of the support 120 assemblies 18 located at either side of the board at the centre of the board are inclined at approximately 45° to hold the centre of the board away from the floor surface. The end of the board with the hole 16 is propped up just clear of the 125 ground by a golf ball 26. Thus the board 10 is inclined downwardly towards the hole 16. The platform 14 is also inclined downwardly towards the hole 16 so that a person is able to stand at the same level and inclination as the putting surface.

The person may hit a succession of balls down the putting surface, each ball passing through the hole 16 on to the floor surface 24 to make way for the next ball. In Figure 2, the legs of the support 5 assemblies 18 at either side of the central region of the board are inclined at the same angle as the corresponding legs in Figure 1. A pair of support assemblies are located towards the end of the board with the hole 16, and the legs of these 10 assemblies are almost vertical to hold that end of the board well clear of the ground and provide an upwardly sloping putting surface. The platform 14 has been reversed from the position shown in Figure 1 to give an upwardly sloping platform at 15 the same level and inclination as the putting surface. As shown in Figure 3, the platform 28 is located on a platform 30 of uniform depth to bring the overall height and inclination of the platform 14 to the same height and inclination as that of 20 the board 10.

As shown in Figures 4A and 4B, the board support assembly includes the channel shaped member 20 which has an upper flange 32 and a lower flange 34 connected together by a central 25 plate 36. The lower flange 34 extends further in the direction away from the central plate 36 than does the upper flange 32. The flanges 32 and 34 converge slightly towards each other in the direction away from the plate 36 under their 30 natural flexure. When the channel shaped member is attached to the side of the board 10 the edges of the flanges are flexed outwardly as the channel shaped member is pushed over the edge of the board so that they extend parallel to one another 35 as shown in Figure 4B. The natural flexure of the flanges 32 and 34 urging them towards each other tends to hold the channel shaped member on the side of the board. As shown in Figure 4A and Figure 5 the board 10 is formed with recesses 40 38 on its upper and lower edges to assist in attaching the assemblies on to the board and to accurately locate assemblies. The leg 22 is pivotally attached to the channel shaped member 20 by a nut and bolt 40 which passes through a 45 hole in the leg 20 and the plate 36 to frictionally grip the leg to the member 20 and allow the leg to be held in the required position under the weight of the board.

As shown in Figure 5, the board 10 is covered 50 with an artificial grass surface 42 comprising a polypropylene mesh backing having a layer of nylon fibres 42. The backing 42 extends over the putting surface 12 and covers the adjoining sides of the board 10. The platform 14 is also covered 55 with a polypropylene mesh backing having a layer of nylon fibres.

As shown in Figures 5 and 6, the board 10 is formed from two board sections 44 which are connected together by the backing 42. As the 60 backing 42 is flexible, the putting surfaces on the board sections 44 may be folded towards each other, as shown in Figure 6, about a hinge 46, to afford a shape convenient for storage. The length of the folded structure is 1.2 metres. The hinge is 65 reinforced by a backing tape 48, part of which is shown in Figure 6.

If the board sections 44 were only connected by the flexible hinge 46 then, when the board was in the position shown in Figure 1 or 2, the board 70 would tend to collapse about the central hinge. Accordingly a channel shaped member is arranged to extend over the join between the board sections, the upper and lower flanges 32 and 34 and the central plate 36 each assembly 18 75 providing tne required rigidity across the hinge.

As shown in Figure 6, each end of the board 10 may have a hole 16, or indeed there may be two holes 16 at one end of the board.

Although the drawings illustrate situations 80 where the putting surface is either uphill or downhill, it will be appreciated that by suitably adjusting the orientation of the legs 22 on opposite sides of the board a putting surface which slopes from side to side, with or without 85 being inclined in the direction of the put, can be provided.

It will also be appreciated that although the putting surface shown in the drawings is provided by a substantially planar surface, the board 10 90 could be made of a material which allows flexure of the board to provide an undulating putting surface or indeed any shaped putting surface that is likely to be encountered on a golf course.

The board 10 is made of expanded polystyrene 95 to afford a lightweight unit. The legs 22 and the channel shaped members 20 are moulded from plastics.
