DESCRIPTION OF THE PREFERRED EMBODIMENTS

The detailed embodiments of the present invention are disclosed herein. It should be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limiting, but merely as the basis for the claims and for teaching one skilled in the art how to make and/or use the invention.
With reference to the various figures, a practice putting apparatus 10 is disclosed. The practice putting apparatus 10 is generally composed of an elongated putting mat 12 having a length of approximately 26.5 inches and a width of approximately 9.5 inches. However, it is contemplated that other sizes may be employed without departing from the spirit of the present invention; for example, a 6 foot long embodiment has been contemplated. The practice putting apparatus 10 is designed on a small scale so that golfers may concentrate upon a shorter stroke while practicing their putting. The concept of “start close to learn fast” is applied, thereby developing rhythm and feel more readily.
With this in mind, and as will be discussed in greater detail below, the present practice putting apparatus 10 generally includes a foam core 14 having an upper surface 14 a and a lower surface 14 b, a printed fabric putting surface 16 secured to the upper surface 14 a of the foam core 14 and a sponge rubber base 18 secured to a lower surface 14 a of the foam core 14. The fabric putting surface 16 includes an upper surface 20 with markings designed to facilitate putting practice and golf like competition in an efficient, convenient and effective manner.
In particular, the putting surface 16 includes a first end 22 and a second end 24. A circular marking for a putting hole 26 is located adjacent the first end 22. This marking is sized to replicate a standard putting hole and is, therefore, 4.25 inches in diameter.
Within the putting hole 26 is a centrally located circular recess (or hole) 28. This recess 28 forms the focus of a golfer as he or she putts along the putting surface 16 in a manner discussed below in greater detail and ultimately stresses the golfer, forcing the golfer to advance his or her skill level. The recess 28 is sized to have a diameter which is slightly smaller than the diameter of a conventional golf cup (that is, 4.25 inches) and is dimensioned such that a ball struck from the second end 24 of the putting surface 16 will stop and sink within the recess 28 when properly struck by a golfer. With this in mind, the recess 28 is approximately 1 inch in diameter to approximately 4 inches in diameter, more preferably, approximately 1.5 inches in diameter to approximately 1.875 inches in diameter, although those skilled in the art will appreciate that the size may be varied to suit specific purposes without departing from the spirit of the present invention. The depth of the recess 28 also plays a role in stopping a properly struck ball as it moves toward the recess 28. With this in mind, the depth of the recess 28 (and, in accordance with a preferred embodiment where the recess 28 extends fully through the putting mat 12 and is at least partially defined by the support surface 29 upon which the putting mat 12 sits, the thickness of the putting mat 12) is such that a properly struck ball (for example, a ball which would otherwise roll 15 inches to 18 inches past the recess 28) is retained by the recess 28. In accordance with a preferred embodiment, recess 28 depth and the mat 12 thickness is approximately 0.236 inches (i.e., 6 mm).
Extending from the putting hole 26 toward the second end 24 of the putting surface 16 are a series of transverse lines 30 a-i marking specific locations from which a golfer is to putt as he or she practices in accordance with the present invention. In particular, nine equally spaced lines 30 a-i are formed along the putting surface 16 as the putting surface 16 extends from the putting hole 26 to the second end 24 thereof. Alignment and putting practice is further enhanced by the provision of a perpendicular line 32 generally extending from the second end 24 of the putting surface 16 toward the putting hole 26. The perpendicular line 32 extends through the middle of the transverse lines 30 a-i and aids in alignment of putting in accordance with the present invention. The transverse lines 30 a-i also serve as a putting face alignment. The perpendicular line 32 also serves as putter head path alignment.
In accordance with a preferred embodiment of the present invention, the first transverse line 30 a is positioned approximately 3.0 inches from the front of the putting hole 26. Thereafter, the transverse lines 30 b-i are spaced approximately 2.0 inches from the next line. Although preferred distances are disclosed in accordance with a preferred embodiment of the present invention, the distances may be varied without departing from the spirit of the present invention. While nine transverse lines creating an eighteen hole practice routine are contemplated in accordance with the present invention, golfers may simply start with close putts and progress to longer putts as their skill level advances.
In practice, the present putting surface 16 and the associated markings are designed to allow a golfer to play eighteen holes and maintain a score as he or she putts. Scoring is maintained in accordance with traditional birdie, par, and bogey concepts. In particular, the golfer starts at the closest transverse line 30 a placing the ball just behind the line 30 a and putting toward the recess 28 located within the center of the putting hole 26. If the golfer is able to stop the ball within the recess 28 a score of −1, birdie, is provided (just as if a golfer were to birdie a hole and go to one under par). If the ball does not sit within the recess 28 but remains on the putting surface 16 a score of even par (or zero) is accorded and a score of +1, bogey, is accorded if the golfer strikes the ball and it falls off the first end 22 of the putting surface 16. This procedure is repeated nine times with the golfer moving further from the putting hole 26 each time. The front nine has then been completed.
Thereafter, the golfer will play the back nine, starting at line 30 i: or hole ten, and begin moving closer to the putting hole 26 moving one transverse line at a time until the golfer makes his or her eighteenth shot at the closest transverse line 30 a. In this way, a golfer is provided with an enjoyable and convenient way of improving his or her skills. The putting green also enhances the golfers' ability to keep score, thereby allowing the golfer to attempt to break his or her record each time he or she chooses to practice with the present putting apparatus.
As mentioned above, the present putting apparatus 10 is formed with a foam core 14, a printed fabric (or cloth) putting surface 16 and a sponge rubber base 18. In accordance with a preferred embodiment of the present invention, the printed fabric putting surface 16 and the sponge rubber base 18 are respectively heat bonded to the foam core 14 in a manner that allows for the creation of a highly effective, durable and aesthetically pleasing putting apparatus. The printed artwork applied to the upper surface 20 of the putting surface 16 is applied via sublimation. More particularly, after securing the fabric putting surface 16 to the foam core 14 via heat transfer and applying the sponge rubber base 18, a sublimation process is used in transferring artwork to the upper surface 20 of the fabric putting surface 16. In accordance with a preferred embodiment of the present invention, the putting surface is composed of a polyester fabric although other putting surfaces may be utilized without departing from the spirit of the present invention.
With regard to the foam core 14, foam density is utilized to replicate various putting surface speeds. In particular, a lower density foam core 14 may be utilized if the golfer is not highly skilled and/or commonly plays upon slower putting greens while a higher density foam core 14 may be used for highly skilled golfers and/or those golfers who commonly play on putting greens which are relatively fast.
In accordance with a preferred embodiment, and in providing a medium speed green, the putting surface is a 2-ounce per square yard interlock polyester, which is heat bonded to a polyester foam core having a density between approximately 1.3 lbs/ft³and approximately 1.4 lbs/ft³. The sponge rubber base is 3/16 inches thick and is heat bonded to the foam core.
Although a specific foam density is disclosed in accordance with a preferred embodiment of the present invention, it is contemplated the density of the foam core may vary between approximately 1.0 lbs/ft³and approximately 6.0 lbs/ft³depending upon the desired speed of the putting surface. With this in mind, it is further contemplated that various combinations of fabric and foam may be utilized so long as the speed of the putting apparatus is maintained between approximately 5 feet and 20 feet as measured by the Stimp Meter.
While various preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention.
