A system for practicing golf is disclosed. The system includes a golf tee holder, a lie modifying wedge, a lie modifying sheet, and a lie modifying bag. The golf tee holder is a small, rubber component placed under a driving range mat, which holds a real golf tee at an adjustable height. The lie-modifying wedge is foam wedge that is placed under or on top of the driving range mat to manipulate the lie of the golf ball on the driving range mat amongst uphill, downhill, and side-hill lies. The lie-modifying sheet and lie-modifying bag are relatively flat components places on top of and anchored to the driving range mat and used as surfaces from which to hit golf balls from different materials simulating hazards on a golf course, such as long grass, a hard pan lie, and a sand trap.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the invention

[0002] This invention relates to a golf tee holder and a system for practicing golf.

[0003] 2. Discussion of related art

[0004] Golf players spend a great deal of their practice time at driving ranges where they can hit real golf balls using full swings. Most golf players prefer to practice hitting golf balls from natural turf. However, many driving ranges today do not have natural turf and only offer their patrons artificial driving range mats from which to hit.

[0005] The typical system for hitting a golf ball from an artificial driving range mat includes the mat itself with a hitting surface and an artificial tee made of a molded material. Players can either hit golf balls from the hitting surface itself or tee the ball up on the artificial tee. The artificial tee is a cylindrical in shape and extends upwards through a hole in the driving range mat to a set height above the hitting surface. The driving range mat is flat, and there is only one surface from which the golf players can hit.

[0006] One disadvantage of this system is the artificial tee does not allow players to use real, wooden tees when practicing on driving range mats. Another disadvantage is the artificial tee does not allow players to adjust the height at which their golf ball is teed when practicing on the driving range mats. A further disadvantage is the golf players can only practice from flat lies from a surface that simulates hitting from very short grass.

DETAILED DESCRIPTION OF THE INVENTION

[0073] FIGS. 1 and 2 of the accompanying drawings illustrate a golf tee holder 30 according to an embodiment of the invention. The golf tee holder 30 includes a base portion 32 and a holding piece 34.

[0074] The base portion 32 is in the form of a circular disk made from a flexible, rubber-like material. The base portion 32 has upper and lower horizontal surfaces 36 and 38 and a circular outer edge 40. The outer edge 40 has a diameter 42 of 55 mm. The base portion 32 has a thickness 44 as measured over the upper 36 and lower 38 horizontal surfaces of 5 mm.

[0075] The holding piece 34 is in the form of a cylinder co-molded with, and made from the same material as, the base portion 32. The holding piece 34 extends upwardly from a central region of the base portion 32. The holding piece 34 has a horizontal upper surface 46 and a circular outer edge 48. The outer edge 48 has a diameter 50 of 15 mm. The holding piece 34 has a height 52 as measured over the upper horizontal surface 36 of the base portion 32 and the upper horizontal surface 46 of the holding piece 34 of 25 mm.

[0076] A circular opening 54 is a formed through the golf tee holder 30. The opening 54 extends into the upper horizontal surface 46, through the holding piece 34 and the base portion 32, and out of the lower horizontal surface 38 of the base portion 32. The opening 54 has a diameter 56 of 3 mm.

[0077] FIGS. 3 and 4 illustrate a typical driving range mat 58. The driving range mat includes a lower layer 60, an upper layer 62, and a circular mat hole 64.

[0078] The lower layer 60, made from a foam-like material, includes a lower mat surface 66 and a circular base portion groove 68. The upper layer 62, made of artificial turf, includes a hitting surface 70. The driving range mat 58 is square with side lengths 72 of 1.5 m and has a mat thickness 74 as measured over the hitting surface 70 and the lower mat surface 66 of 30 mm.

[0079] The circular mat hole 64 is formed through the driving range mat 58. The mat hole 64 extends into the hitting surface 70 through the upper layer 62 and lower layer 60 and out the lower mat surface 66. The mat hole 64 has a diameter 76 of 17 mm.

[0080] The circular base portion groove 68 is formed on the lower mat surface 66. The base portion groove 68 is concentric with the mat hole 64 and has a diameter 78 of 57 mm. The base portion groove 68 extends upwardly into the driving range mat 58 to a depth 80 of 6 mm.

[0081] FIG. 5 illustrates the golf tee holder 30 and the driving range mat 58 resting on a horizontal surface 82. The mat hole 64 is positioned around the holding piece 34. The base portion 32 is positioned in the base portion groove 68. The lower mat surface 66 and the lower horizontal surface 38 of the base portion 32 are coplanar and rest on the horizontal surface 82. The upper horizontal surface 46 of the holding piece 34 is coplanar with the hitting surface 70 of the driving range mat 58.

[0082] FIG. 6 illustrates a typical golf tee 84. The golf tee 84 includes a stem 86 and a supporting component 88. The stem 86 is cylindrical with a diameter 90 of 5 mm and ends in a point. The supporting component 88 is a circular, concave platform with a diameter 92 of 12 mm and an upper surface 94. The golf tee 84 has a height 96 of 55 mm.

[0083] In use, as illustrated in FIG. 7, the golf tee holder 30 is placed on the horizontal surface 82. The driving range mat 58 is placed on the horizontal surface 82 such that the mat hole 64 is positioned over the holding piece 34. The base portion 32, now positioned in the base portion groove 68, is secured between the horizontal surface 82 and the lower layer 60 of the driving range mat 58. The holding piece 34 extends upwardly through the mat hole 64 such that the upper horizontal surface 46 of the holding piece 34 is coplanar with the hitting surface 70 of the upper layer 62 of the driving range mat 58.

[0084] The stem 86 of the golf tee 84 is inserted into the opening 54. The opening 54 expands slightly when the stem 86 is inserted because of the flexible material from which the holding piece 34 is made. The golf tee 84 is held in place by frictional forces exerted on the stem 86 from all directions by the opening 54. The supporting component 88 is held at an adjustable tee height 98 as measured over the upper surface 94 of the supporting member 88 and the hitting surface 70 of the driving range mat 58.

[0085] A player can lower the adjustable tee height 98 by manually pushing the golf tee 84 farther into the opening 54. Conversely, the player can raise the adjustable tee height 98 by pulling the golf tee 84 farther out of the opening 54. A golf ball 100 is then placed on the supporting component 88 where it rests at the adjustable tee height 98. After setting the adjustable tee height 98, the player can use a desired first golf club to strike the golf ball 100 off the golf tee 84.

[0086] When the golf ball 100 is struck, the golf tee 84 usually undergoes some lateral forces. Such lateral forces cause the golf tee 84 along with the holding piece 34 to bend out of place temporarily immediately after the golf ball 100 is struck. The flexibility of the material from which the golf tee holder 30 is made allows the holding piece 34 to return to its original position, whether or not the golf tee 84 has become dislodged from the opening 54. However, the golf tee holder 30 remains in place because the base portion 32 is secured within the base portion groove 68 and the holding piece 34 is positioned in the mat hole 64.

[0087] If the golf tee 84 is not dislodged from the opening 54, the player may or may not want to change the adjustable tee height 98 before hitting another golf ball from the golf tee 84, using either the first golf club or a desired second golf club.

[0088] If the golf tee 84 has become dislodged from the opening 54, the player can reinsert the stem 86 into the opening 54. The player can then set the adjustable tee height 98 to either the same height or a different height before hitting another golf ball from the golf tee 84, using either the first golf club or a desired second golf club.

[0089] Often, the lateral forces applied to the golf tee 84 are great enough, despite the holding piece 34 being flexible, to break the golf tee 84. In which case it is possible for the stem 86 of the golf tee 84 to become lodged in the opening 54. In use, and as illustrated in FIGS. 8, 9, and 10, the golf tee holder 30 is removed from beneath driving range mat 58 and the stem 86 is lodged in the opening 54. To remove the lodged stem 86, a second stem 102 of a second golf tee 104 is inserted into the opening 54. When the second stem 102 has been inserted far enough into the opening 54 to contact the lodged stem 86, the second stem 102 pushes the lodged stem 86 towards the lower horizontal surface 38 of the base portion 32. Once the second golf tee 104 is nearly completely inserted into the opening 54 and the second stem 102 extends to the lower horizontal surface 38 of the base portion 32, the lodged stem 86 is dislodged from the opening 54. The player can then continue normal use of the golf tee holder 30.

[0090] FIGS. 11, 12A, 12B, 12C, 12D and 13 illustrate a lie-modifying component 106 and the driving range mat 58 on top of the horizontal surface 82.

[0091] The lie-modifying component 106 is wedged shaped and made from a soft foam-like material. The lie-modifying component 106 has an upper surface 108 and a lower surface 110. The lie-modifying component 106 has a length 112 of 1.5 m, a width 114 of 0.75 m, and a height 116 of 100 mm. A cross section of the lie-modifying component is a right triangle with the height 116 of 100 mm and a hypotenuse 118 of 756 mm. The upper surface 108 and the lower surface 110 are rectangular in shape.

[0092] The lower surface 110 of the lie-modifying component 106 is on the horizontal surface 82 and beneath the driving range mat 58. The lower mat surface 66 of the driving range mat 58 completely covers the upper surface 108 of the lie-modifying component 106. An outer region of the lower mat surface 66 of the driving range mat 58 is raised to the height 116 of the lie-modifying component 106.

[0093] A first portion 120 of the hitting surface 70 is located directly above a first portion 122 of the driving range mat 58. The first portion 122 of the driving range mat 58 is directly on the horizontal surface 82. The first portion 120 of the hitting surface 70 remains parallel to the horizontal surface 82. The driving range mat 58 bends upward at mat bending point 124. A second portion 126 of the hitting surface 70 is located directly above a second portion 128 of driving range mat 58. The second portion 128 of the driving range mat 58 is on the lie-modifying component 106. The second potion 126 of the hitting surface 70 is now at an angle to the horizontal surface 82.

[0094] In use, to simulate a side hill lie with the golf ball 100 below the golf player's feet 130, a golf player places the golf ball 100 on the first portion 120 of the hitting surface 70. The golf player then stands on the driving range mat 58 with his feet 130 on the second portion 126 of the hitting surface 70. The golf player's feet 130 will be higher than the golf ball 100 because the second portion 126 of the hitting surface 70 is higher than the first portion 120 of the hitting surface 70. The golf player then hits the golf ball 100 from the first portion 120 of the hitting surface 70 with a golf club. As illustrated in FIG. 12B, to simulate a side hill lie with the golf ball 100 above the feet 130, the golf player places his feet 130 on the first portion 120 of the hitting surface 70 and the golf ball 100 on the second portion 126 of the hitting surface 70.

[0095] As illustrated in FIGS. 12C and 12D, uphill and downhill lies can also be simulated by reconfiguring the driving range mat 58, the lie-modifying component 106, and the golf player's feet 130. To simulate either an uphill or downhill lie, one foot 130 is placed on the first portion 120 of the hitting surface 70 and the other foot 130 on the second portion 126.

[0096] Alternatively, the lie-modifying component 106 can be placed on top of the driving range mat 58. FIG. 14 illustrates the lie-modifying component 106 on the driving range mat 58. The second portion 126 of the hitting surface 70 is covered by the lie-modifying component 106. The upper surface 108 of the lie-modifying component 106 is now exposed. The golf ball 100 or the golf player's feet 130 are placed on either the upper surface 108 of the lie-modifying component 106 or on the first portion 120 of the hitting surface 70 of the driving range mat 58 to simulate uphill, downhill, and side hill lies.

[0097] FIGS. 14, 15, and 16 illustrate a lie-modifying sheet 132 placed on the driving range mat 58 on the horizontal surface 82. The lie-modifying sheet 132 includes an anchoring formation 134, an upper surface 136, a lower surface 138, and long artificial grass 140. The lie-modifying sheet 132 is rectangular in shape with a length 142 of 60 cm and a width 144 of 30 cm.

[0098] The anchoring formation 134 extends downward from the lower surface 138 of the lie-modifying sheet 132. The anchoring formation 134 is cylindrical in shape.

[0099] The long artificial grass 140 is attached to the upper surface 136 of the lie-modifying sheet 132. The long artificial grass 140 has a height 168 of 70 mm.

[0100] The hitting surface 70 of the driving range mat 58 is covered with artificial turf 146 which does not extend above the hitting surface 70. The lie-modifying sheet 132 is on the driving range mat 58 placed on the horizontal surface 82. The anchoring formation 134 is inserted into the mat holes 64 to secure the lie-modifying sheet 132 to the driving range mat 58. The lower surface 138 of the lie-modifying sheet lies directly on and covers a covered portion 148 of the hitting surface 70. An exposed portion 150 of the hitting surface 70 remains uncovered.

[0101] In use, to simulate hitting from the rough, a golf player places the golf ball 100 on the lie-modifying sheet 132 resting the golf ball 100 in the long artificial grass 140. The golf player places his feet 130 on the exposed portion 150 of the hitting surface 70 of the driving range mat 58. The golf player may then strike the golf ball 100 out of the long artificial grass 140 located on top of the lie-modifying sheet 132. Lateral forces are exerted on the lie-modifying sheet 132 when the golf player hits the golf ball. The anchoring formation 134 prevents the lie-modifying sheet 132 from sliding off the driving range mat.

[0102] FIGS. 17, 18, and 19 illustrate a lie-modifying bag 152 on top of the driving range mat 58 on the horizontal surface 82. The lie-modifying bag 152 has an anchoring formation 154, an upper surface 156, a lower surface 158, and sand filler 160. The lie-modifying bag 152 is pillow-shaped with a length 162 of 60 cm, a width 164 of 30 cm, and a height 166 of 8 cm.

[0103] The anchoring formation 154 extends downward from the lower surface 158 of the lie-modifying bag 152. The anchoring formation 154 is cylindrical in shape.

[0104] The lie-modifying bag 152 is on the driving range mat 58 placed on the horizontal surface 82. The anchoring formation 154 is inserted into the mat holes 64 to secure the lie-modifying bag 152 to the driving range mat 58. The lower surface 158 of the lie-modifying bag 152 lies directly on and covers the covered portion 148 of the hitting surface 70. An exposed portion 150 of the hitting surface 70 remains uncovered.

[0105] In use, to simulate hitting from a sand trap, the golf player places the golf ball 100 on the upper surface 156 of the lie-modifying bag 152. The golf player places his feet 130 on the exposed portion 150 of the hitting surface 70 of the driving range mat 58. The golf player then strikes the golf ball 100 from the upper surface 156 of the lie-modifying bag 152. When the golf ball 100 is struck, the upper surface 156 of the lie-modifying bag 152, will depress into the sand filler 160 of the lie-modifying bag 152. The result is that the golfer will get a sensation similar to that of hitting a golf ball 100 out of a sand trap. Lateral forces are exerted on the lie-modifying bag 152 when the golf player hits the golf ball 100. The anchoring formation 154 prevents the lie-modifying bag 152 from sliding off the driving range mat 58.

[0106] One advantage of this system is the golf tee holder 30 allows the player to use real golf tees when practicing on artificial driving range mats, more closely simulating the feel of hitting a golf ball off natural grass. Another advantage is the golf tee holder 30 allows the player to adjust the tee height when practicing on artificial mats. Another advantage is the holding piece 34 is not exposed, therefore wear on the golf tee holder 30 is at a minimum thus golf tee holder 30 should have a very long useful life.
