ABSTRACT:
A golf swing practice mat for placement on an underlying base is provided to aid a golfer in improving his or her swing of a golf club having a club head, said swing comprising a swing arc having a bottom-most portion thereof, said golf swing practice mat comprising: (a) a low friction, flexible and resilient top sheet that is directly contacted by the club head, and has a rigidity of 40 pounds per square inch or less; (b) a supporting pad for supporting the top sheet and for providing space for the top sheet to yield to and accommodate the bottom-most portion of a reasonably well-aligned swing arc, the supporting pad being compressible to 50% of its resting height in any area near its center line by an applied pressure thereupon of 0.0056 Mpa (8 psi) or less; and (c) a self-supporting, generally flat, bottom sheet around which the ends of the top sheet may be wrapped and attached thereto and which provides one or more sturdy points to which suitable means may be attached to anchor the mat to the underlying base, the supporting pad supporting the top sheet a finite distance above the bottom sheet. The golf swing practice mat avoids the mechanical limitations and problems associated with prior art mats. In typical usage, the respective properties of the top sheet and the bottom pad together enable the whole mat to function so that--like a natural-grass-covered fairway--it imposes very little resistance as it readily yields to and accommodates the bottom-most portion--between the bottom of the ball and the underlying ground/base--of any full, and reasonably well aligned golf club swing arc. Golf clubs that are swung through arcs which hit down before one's stance and rotation center, and would otherwise tend to dig into a natural earth base, or a typical practice-range mat, impact relatively softly and slide forward without appreciable loss of momentum, and allow the golfer to complete the somewhat mis-aligned swing-arc without discomfort and deterrence to future efforts.
