Description

GOLF DRIVING MAT
The present invention relates to a golf driving mat and a golf driving mat system incorporating the same. The golf driving mat and golf driving mat system of the present invention are to be known as the TrueStrikeTM golf driving mat and golf driving rnat system.
Golf driving mats and golf driving mat systems are used at golf ranges and golf tees, in particular during the Winter. The construction of existing golf driving mats is, however, such that golfers can be given an unrealistic impression of shots struck therefrom. With existing golf driving mats, where a golfer hits a "clean" shot, that is, a correct shot, the resulting shot is substantially the same as would be achieved on a natural ground surface, but where a golfer hits a "fat" shot, that is, where the club head hits the ground behind the golf ball, typically about 20 mm behind the golf ball, the resulting shot is often an apparently good shot, instead of what should be a poor shot, as the club head re-bounds from the surface of the mat and meets the golf ball at a reasonable angle and at only a slightly reduced speed. On the natural surface of a golf course, where a golfer hits a "fat" shot, the club head digs into the ground, to a lesser or greater extent depending upon the condition of the ground surface, causing the club head to be slowed considerably and thereby produce a poor shot. Thus, when a golfer hits a "fat"
shot from existing golf driving mats, the resulting shot would often appear to be a good shot, leading the golfer to believe that the swing is good, when, in fact, the swing is poor, as the same "fat" shot on a natural ground surface would produce a poor shot, with the consequence that poor swing technique is developed.
Golf driving mats have been developed which provide a cushioning effect, for example, as disclosed in GB-A-2315024, US-A-4955611 and US-A-5273285, but these golf driving mats are still not considered adequately to provide a true impression of the strike of a golf ball from any given swing. It will also be noted that golf putting mats axe known, one such mat being disclosed in DE-A-3926052.

Figures 1 to 8 illustrate a golf driving mat system including a golf driving mat in accordance with a first embodiment of the present invention.
The golf driving mat system comprises a base unit 1 on which a golfer stands to hit a golf shot, and a golf driving mat 3 which is mounted in the base unit 1 and from which golf balls are struck by a golfer.
The base unit 1 comprises a base 5 which is located on a ground surface, and a sheet 7 which is located on the base 5 and on which a golfer stands to hit golf shots.
In this embodiment the base 5 includes first and second mat recesses 9a, 9b located at respective sides thereof in which the golf driving mat 3 is selectively disposed, and a sheet recess 11 in which the sheet 7 is located, and the sheet 7 includes a clearance aperture 15 through which the golf driving mat 3 is presented, with the sheet 7 being locatable in the sheet recess 11 in one of two positions such that the clearance aperture 15 therein overlies one of the first and second mat recesses 9a, 9b. With this configuration, the golf driving mat system can be easily configured for both left-handed and right-handed golfers, with the golf driving mat 3 being located in the first mat recess 9a for use by a left-handed golfer and the second mat recess 9b for use by a right-handed golfer, and the sheet 7 being disposed such that the clearance aperture 15 therein overlies the respective one of the first and second mat recesses 9a, 9b.
The golf driving mat 3 comprises a body unit 17, a receptacle 19 which is disposed within the body unit 17 and includes an upper, flexible member 21, a lower member 22 and a cavity 23, filled with a viscous material 25, therebetween, and an upper, ball-receiving unit 27 disposed over the flexible member 21 of the receptacle 19.
The body unit 17 includes a main body 29 within which the receptacle 19 is disposed.
The main body 29 includes first and second anchor pins 33a, 33b at one, the rear, end thereof in the direction of hitting to which the receptacle 19 is fixed such as to prevent movement of the receptacle 19 forwardly on hitting golf balls from the golf driving mat 3.
The main body 29 further includes an impact element 35 which extends along the lower surface thereof in the direction of hitting, which impact element 35 acts to provide an impact surface such that, should a golfer hit down through the receptacle 19, the golf club re-bounds from the impact element 35 without any significant jarring. In this embodiment the impact element 35 is formed of a ntbberised material, preferably a rubber.
The receptacle 19, in this embodiment an enclosed, flexible bag, is a planar rectangular member having a predetermined depth, in this embodiment of about 20 mm, such that, where filled with a viscous material 25, in this embodiment a viscous foam material, the upper, flexible member 21 of the receptacle 19 simulates a ground surface, typically a turfed ground surface. In this embodiment the receptacle 19 is fabricated from a ruckable material, such that, when a golfer hits a "fat" shot, the flexible member 21 is rucked up, which rucking up, together with the action of the underlying viscous material 25, causes the speed of the club head to be slowed in the same manner as when hitting a "fat"~ shot on a turfed ground surface.
In one embodiment the receptacle 19 is formed of a synthetic material, preferably polyvinyl chloride (PVC). In another embodiment the receptacle 19 can be formed of a rubberised material, preferably a rubber, and more preferably a synthetic rubber. In a preferred embodiment the receptacle 19 is formed of a resilient material.
The receptacle 19 includes first and second rear apertures 47a, 47b at the rear end thereof in which the anchor pins 33a, 33b on the main body 29 are located to fix the position of the receptacle 19 in the main body 29.
In this embodiment, as illustrated in Figure 6, the viscous material 25 is a viscous foam material, here a block of viscous foam material. In a preferred embodiment the viscous foam material is a visco-elastic foam material, for example, a memory foam material, such as supplied by Tempurpedic.
In an alternative embodiment the viscous material 25 could comprise a resilient skeletal structure which is filled with a viscous medium.
In one embodiment, as illustrated in Figure 7, the resilient skeletal structure comprises an intertwined filamental structure, such as comprising irregular filaments, typically coiled filaments, for example, coiled plastic filaments.
In another embodiment, as illustrated in Figure 8, the resilient skeletal structure comprises a regular filamental structure, typically formed of a plastics material.
In one embodiment the viscous medium comprises a gel, for example, an aqueous gel.
In a preferred embodiment the gel comprises a petroleum jelly. In an alternative embodiment the viscous medium could be a syrup, such as a corn syrup. In another alternative embodiment the viscous medium could be an oil, such as a silicone oil. In a further alternative embodiment the viscous medium could be a paste. In a yet further alternative embodiment the viscous medium could comprise a particulate material in a carrier medium, for example, a gel or an oil, such as a silicone oil. In yet another alternative embodiment the viscous medium could be a particulate material.
Examples of particulate materials include plastic particles, metal particles and plastic-coated metal particles.
The ball-receiving unit 27 comprises a frame 51 which is removably attached, in this embodiment by screws 54, to the main body 29 of the body unit 17, and a ball-receiving member 53 which is attached to the frame 51 and on which golf balls to be hit are located. In being removable, the ball-receiving unit 27 allows for replacement when damaged, typically through wear.

In this embodiment the upper surface of the ball-receiving member 53 is a smooth surface. In an alternative embodiment the upper surface of the ball-receiving member 53 can be a non-smooth surface, for example, a roughened or ribbed surface.
5 In this embodiment the ball-receiving member 53 comprises a resilient material, typically a fabric material containing Lycra°, for example Cordura~ as available from E.I. du Pont de Nemours and Company, Wilmington, US.
With this construction, when a golfer makes a good swing and hits a golf ball with a 10 "clean" strike, the golf driving mat 3 reacts in the same manner as would a natural ground surface, as illustrated in Figure 9. However, when a golfer makes a poor swing which is such as to cause the club head to hit the ball-receiving member 53 of the ball-receiving unit 27 behind the golf ball, and hence the flexible member 21 of the receptacle 19, that is, hits the shot "fat", the flexible member 21, under the reaction of 15 the viscous material 25, acts to cause the club head to dig into the golf driving mat 3, which causes the club head to be slowed down and make little or no contact with the golf ball, as illustrated in Figure 10.
By altering the thickness of the flexible member 21 of the receptacle 19 and the ball-receiving member 53 and the characteristics of the viscous material 25, the golf driving mat 3 can be configured to simulate different ground conditions, from firm to heavy turfed ground, and even sand bunkers. In this embodiment, a golfer is able to select between a plurality of different golf driving mats 3 which are representative of different ground conditions.
