Description

Currently, golf tees used in any practice facility do not allow for easy or precise height adjustment, which is paramount for effective practice. For example, current golf tees for use at golf driving ranges equipped with artificial turf mats for hitting balls are available in a variety of heights. However, these heights are fixed based on the golf tees available. In other words, each golf tee has only one height. Therefore, to achieve multiple heights, multiple golf tees are required. Traditionally, there are three sizes available: low, medium, and high tee heights. To switch between various tee heights, a golfer lifts the mat, pulls a golf tee through a hole in the mat, inserts a golf tee with the desired height through the hole, and then replaces the portion of the mat that was lifted or moved.

As another example, current golf tees for use at golf driving ranges with natural grass for hitting balls are typically the same tees used during a round of play. Although a single tee can be used for multiple heights, every time a golfer wants to hit a ball for practice, they must bend down, insert a new tee, find the correct height, and place the ball on the tee.

On the golf course, different golfers have different ball height preferences during driver shots, and the difference in ball height preferences can be nearly infinite. As a result, there is likely to be variance in the height that golfers are using each time they insert a tee into the ground.

What's needed is a more consistent golf tee system.

A golf tee system is discussed that has a tee and an anchor. The tee is height adjustable relative to the anchor. The first anchor includes a cap, a stem, and a tip. The stem can be internally, externally, or a combination thereof. The second anchor includes a stem and a base. The stem can be internally threaded. Both the first anchor and the second anchor can be constructed of three pieces (e.g., a removable cap, a removable stem, or removable portions thereof) and can provide access to the interior cavity of their respective stems.

For ease of discussion and clarity, ball height, tee height, or head height is relative to the ground on which the golfer is standing and from which the driver shot occurs. However, ball height, tee height, or head height is not intended to be so limited based on a relative distance to the uppermost surface of the anchor or on one or more absolute lengths, heights, or distances.

FIG. 1A shows a tee 100. FIG. 1B shows a cross-sectional view of the tee 100 taken along line II. The tee 100 includes a shaft 104, a head 102 at a first end of the shaft 104, and a tip 106 at a second end of the shaft 104. The head 102 can be flat or concave. The tee length T _L can be any suitable size. For example, the tee length T _L can be in the range of 25.4 to 127 mm.

In one example, the tee length T _L can be less than or equal to the sum of half the diameter of the golf ball and the maximum legal driver head height (i.e., tee length = (0.5 x (golf ball diameter)) + (maximum legal driver head height)). Currently, an "American" golf ball, as determined by the USGA Equipment Rules, can be 42.67 millimeters or larger in diameter. Alternatively, a "British" golf ball can be 41.1 mm or larger in diameter. Also, under the current USGA Equipment Rules, the maximum distance from the sole to the crown of the club head is 71.12 mm or smaller.

The shaft 104 of the tee 100 may be threaded. The threads may be of any suitable size, including, but not limited to, those ranging from 1/64 inch (0.396875 mm) to 1 inch (25.4 mm), such as in 1/64 inch (or 0.396875 mm) increments. The shaft 104 can include any suitable number of threads, whether total or per inch, including, but not limited to, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 24, 32, 40, 50, 60, 70, 80, 90, 100, up to 2, up to 3, up to 4, up to 5, up to 6, up to 7, up to 8, up to 9, up to 10, up to 11, up to 12, up to 13, up to 14, up to 15, up to 16, up to 18, up to 20, up to 2 up to 4, up to 32, up to 40, up to 50, up to 60, up to 70, up to 80, up to 90, up to 100, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 11, at least 12, at least 13, at least 14, at least 15, at least 16, at least 18, at least 20, at least 24, at least 32, at least 40, at least 50, at least 60, at least 70, at least 80, at least 90, or at least 100, etc. In one example, the shaft 104 is threaded at one or more segments of its length. In another example, the shaft 104 is threaded along the entire shaft length.

FIG. 2A illustrates an anchor 200, such as for use on a natural surface. FIG. 2C illustrates a cross-sectional view of the anchor 200 taken along line II-II. The anchor 200 includes a stem 204, a cap 202 at a first end of the stem 204, and a tip 206 at a second end of the stem 204. The anchor 200 also includes a cavity 220 (e.g., formed by one or more inner walls within the anchor 200), which is sized and shaped to receive and engage the shaft 104, the tip 106, or both. The cavity 220 can be fully threaded, partially threaded, or not threaded at all. In one example, the cavity 220 extends from a side of the cap 202 distal to the stem 204 into the tip 206. In another example, the cavity 220 extends from the side of the cap 202 distal to the stem 204 into the stem 204 without entering the tip 206.

The cap 202 includes a slot 210 that extends from a portion of the cavity 220 in the top portion of the cap 202 or from a portion of the cavity 220 proximal to the cap 202. The slot 210 can accept a device or object (e.g., a screwdriver, a coin, a finger, a fingernail, a spike wrench, a sports wrench, etc.) to secure the anchor 200 into the ground, for example, by screwing, pushing, or twisting. The anchor 200 can include multiple slots 210.

The upper surface of cap 202 can sit flush with the ground, or the bottom surface of cap 202 can rest on the ground. In one example, a portion of the inner wall of cap 202 includes a curved or tapered surface to provide access to the deeper portion of cavity 220, thereby allowing a broken or sheared tee to be removed.

Alternatively or in addition to the slot 210, the portion of the cavity 220 in the side of the cap 202 distal to the stem 204 can be larger than the maximum diameter of the shaft 104 or tip 106 and can be shaped to accept a wrench, such as an Allen wrench or a sports/spike wrench.

The length of the stem 204 can range from 1/64 inch (0.396875 mm) to 3.5 inches (88.9 mm), for example, in 1/64 inch (or 0.396875 mm) increments.

In one example, the stem 204 includes threads 208. The threads 208 may be of any suitable size, including, but not limited to, those ranging from 1/64 inch (0.396875 mm) to 1 inch (25.4 mm), such as in 1/64 inch (or 0.396875 mm) increments. The stem 204 can include any suitable number of threads, whether total or per inch, including, but not limited to, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 24, 32, 40, 50, 60, 70, 80, 90, 100, up to 2, up to 3, up to 4, up to 5, up to 6, up to 7, up to 8, up to 9, up to 10, up to 11, up to 12, up to 13, up to 14, up to 15, up to 16, up to 18, up to 20, up to 2 up to 4, up to 32, up to 40, up to 50, up to 60, up to 70, up to 80, up to 90, up to 100, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 11, at least 12, at least 13, at least 14, at least 15, at least 16, at least 18, at least 20, at least 24, at least 32, at least 40, at least 50, at least 60, at least 70, at least 80, at least 90, or at least 100, etc. In one example, the stem 204 is threaded at one or more segments of its length. In another example, the stem 204 is threaded along the entire stem length.

In one example, the stem 204 is fluted. The flutes provide increased resistance in the ground due to stress (e.g., shear stress) or force exerted on the anchor 200 when the golf ball is launched from the tee 100. The flutes can be any suitable shape, including, but not limited to, hemispherical, conical, pyramidal, rectangular, or triangular. Alternatively, the stem 204 can have one or more protrusions extending outward, downward, upward, or a combination thereof. The flutes create one or more grooves (i.e., grooves cut into the outer surface of the stem 204), while the protrusions extend from the outer surface of the stem 204. In another example, the stem 204 can be fluted and include one or more protrusions.

In one example, the threads, flutes, or protrusions have a diameter (T _D ) that is greater than the cap diameter C _D. In another example, the threads, flutes, or protrusions have a diameter (T _D ) that is less than the cap diameter C _D. In yet another example, the threads, flutes, or protrusions have a diameter (T _D ) that is equal to the cap diameter C _D.

The tip 206 can be sized (e.g., in 1/64 inch (or 0.396875 mm) increments, e.g., ranging from 1/64 inch (0.396875 mm) to 3.5 inches (88.9 mm)) and shaped (e.g., tapered, cylindrical, pointed, conical, pyramidal, triangular, "X" shaped, "+" shaped, rectangular, etc., or combinations thereof) based on the type of ground into which the anchor 200 is being inserted or the ground conditions at the time of insertion. The size and shape can also be selected to improve ease of insertion of the anchor 200 into the ground. For example, when the soil or ground is rocky, the tip 206 can be shorter to reduce the likelihood of breakage and sharper (i.e., have a smaller internal angle) to better penetrate into or between rocks. As another example, when the soil or ground is loose, the tip 206 can be longer to increase the force exerted on the anchor 200 by the ground (thereby requiring a greater force to be exerted on the anchor 200 during a driver shot to cause the anchor 200 to move).

In one example, the cap 202, stem 204, and tip 206 are a single piece. In one example, the cap 202 is removably attached to the stem 204, for example, by threads, detents, a dovetail joint, a tongue and groove, a press fit, or the like, or a combination thereof. Removing the cap 202 from the stem 204 provides access to a deeper portion of the cavity 220, thereby allowing a broken or sheared tee to be removed. In another example, the tip 206 is removably attached to the stem 204, for example, by threads, detents, a dovetail joint, a tongue and groove, a press fit, or the like, or a combination thereof. Removing the tip 206 from the stem 204 allows for replacement or switching of the stem 204, for example, when the tip 206 is damaged or to accommodate different ground or soil conditions.

Figure 3 shows anchor 300 with barbs 302. Anchor 300 is similar to anchor 200, except that anchor 300 includes barbs 302. Barbs 302 can extend outward, downward, upward, or a combination thereof from tip 206 or cap 202 to increase gripping force. Barbs can also extend outward, downward, upward, or a combination thereof from shaft 204, for example, when shaft 204 is not threaded.

FIG. 4A shows an anchor 400, which is intended for use on an artificial surface, for example. FIG. 4B shows a cross-sectional view of the anchor 400 taken along line III-III. The anchor 400 includes a stem 402 and a base 404. The diameter of the stem 402 is sized to fit through a hole in a driving range mat. The diameter of the base 404 is sized to prevent the anchor 400, when inserted into the mat, from being pulled through the hole in the same direction as the stem 402 (i.e., the base diameter is larger than the diameter of the hole in the mat). The anchor 400 also includes a cavity 406 (e.g., formed by one or more interior walls within the anchor), which is sized and shaped to receive and engage the shaft 104 of the tee 100. The cavity 406 can be fully threaded, partially threaded, or not threaded at all.

The length of the stem 402 can range from 1/4 inch (6.35 mm) to 3.5 inches (88.9 mm), for example, in increments of 1/64 inch (or 0.396875 mm). In one example, an anchor can be provided having a first stem height. In another example, two or more anchors can be provided, each having a different stem height.

In one example, the stem 402 and base 404 are a single piece. In another example, the stem 402, or a portion thereof, is removably attached to the base 404, such as by threads, a detent, a dovetail joint, a tongue and groove, a press fit, or the like, or a combination thereof. Removing the stem 402 from the base 404 provides access to a deeper portion of the cavity 406, thereby allowing a broken or sheared tee to be removed.

In one example, a portion of the inner wall of the stem 406 includes a curved or tapered surface 408 on the side of the stem 406 opposite the base 404, providing access to a deeper portion of the cavity 406, thereby allowing a broken or sheared tee to be removed.

In one example, the base 404 includes one or more barbs that extend upward, outward, downward, or a combination thereof to provide a more secure grip on the mat, the ground, or a combination thereof.

FIG. 5A shows an assembled golf tee system 500. FIG. 5B shows a cross-sectional view of the assembled golf tee system 500 along line IV-IV. In one example, the anchor 200 is first inserted into the ground (or mat, if appropriate). The tee 100 is then inserted into the anchor 200. The ball height _BH can be adjusted by rotating the tee 100 clockwise or counterclockwise. The ball height _BH can be the distance from the bottom of the cap 202 (i.e., where the cap 202 will contact and rest on the ground surface) to the ball-contacting surface of the head of the tee when the tee is inserted into the cavity of the anchor.

In one example, the ball height _BH is 86.12 mm. Therefore, having a penetration portion _P of 12.7 mm (i.e., the portion of the tee 100 that extends from the bottom of the cap 202 to the tip 106 of the tee 100; or, the portion of the tee 100 that is at and below the ground surface when the golf tee system 500 is inserted into the ground) provides a tee length _T of 98.82 mm. Alternatively, the penetration portion _P can be 3.175 mm, 6.35 mm, 9.525 mm, or more, thereby providing a tee length _T with a ball height _BH of 86.12 mm, 89.295 mm, 92.47 mm, 95.645 mm, or more. Moreover, the ball height _BH is not intended to be so limited. The ball height _BH can be at least 3.175 mm. Also, the ball height _BH can be adjusted based on the golfer's preferences.

In other words, the tee length T _L is equal to the sum of the ball height B _H and the penetration portion P _P of the tee 100 .

In one example, tee 100 is already inserted and adjusted into anchor 200 prior to insertion of anchor 200 into the ground (or mat, as appropriate). For example, a golfer may adjust ball height _BH at a first driving range. The golfer may then remove fully assembled golf tee system 500 from the ground and then insert the fully assembled golf tee system 500 at a different location on the first driving range or at a second driving range. This provides consistent ball height _BH , for example, from location to location or from driving range to driving range, without the need for additional measurements.

In other words, ball height _BH can remain consistent from hole to hole, range to range, and course to course. Tee 100 can remain fixed relative to anchor 200 by threads, a press fit, a locking mechanism, such as a stop, lock, or plug, or the like.

Additionally, although the tee 100 is discussed as having threads, the tee 100 need not be so limited. For example, the tee 100 could have detents, clips, bumps, indentations, or the like. The tee 100 could be height adjusted by a press fit or by engaging a complementary hole, detent, or clip on the interior wall or surface of the anchor. Thus, an unthreaded tee can be pushed into or pulled out of the anchor to adjust the ball height _BH , although the pushing or pulling may require overcoming one or more forces (e.g., due to a press fit, clip, detent, etc.).

The tee and anchor may each be constructed from a variety of different materials, including, but not limited to, ceramic; metal; organic or inorganic material; wood; one or more plastics; one or more rubbers (including silicone); or the like; or combinations thereof.

A kit including one or more tees, one or more anchors, one or more anchor tips, etc., or combinations or multiples thereof. In one example, the kit can include one anchor and multiple tips, such that no two tips have all of the same characteristics. For example, a first tip can be longer and narrower than a second tip. Or, for example, the first tip can be made from a softer or more flexible material than the second tip. Characteristics can include density, hardness, length, shape, taper, barbs, etc., or combinations or multiples thereof.

In another example, the kit can include one anchor and multiple tips, where the tips are identical.

FIG. 6A shows a golf tee system 600 with a removable cap 615, which is shown slightly removed from the anchor portion 600. The golf tee system has a central shaft 604, on which threads 608 are disposed. The lower section has spikes 606. The threads are configured to bite into the ground and pull the tee system 600 into the ground. FIG. 6B shows the underside of the removable cap 615. As depicted, the anchor portion has a locating pin 614 on the side of the upper surface 603. The pin 614 is designed to locate into a corresponding slot 613 in the removable cap 615. The corresponding slot 613 is shown in FIG. 6B. More than one pin 614 can be positioned on the anchor cap 603. Furthermore, the position of the pin 614 can vary. In some embodiments, for example, the pin 614 can be located on the top surface, as opposed to the side, and function in the same manner. Additionally, there can be more slots 613 than pins 614. In embodiments with additional slots 613, this allows the user to lock the cap 615 into place from more than one starting position. For example, as depicted, there are two slots 613 positioned opposite each other on the removable cap 615. The slots shown can correspond to a single pin 614, or, optionally, can correspond to two pins 614.

Occasionally, the tee 100 may sheer off or separate. Often, this occurs just below the surface of the removable cap 615. In a preferred embodiment, the removable cap 615 is not threaded and has a wide enough opening 612 to allow the tee 100 to pass through. When the tee 100 sheers, the removable cap 615 can be removed. This exposes a portion of the sheared tee, allowing a user to grasp the sheared portion and remove it from the anchor system 600. In various embodiments, the height of the removable cap 615 can be greater than that depicted, and the removable cap 615 can be configured to extend into the portion of the anchor 600 that continues into the ground. In such an embodiment, the removable cap portion is still removable, allowing exposure of the sheared tee portion. For example, in alternative embodiments, such as those described, the removable cap can extend to alternative points on the shaft 604. The cap portion can connect to the anchor body portion in a similar keyed manner, or the two components can be threaded together.

According to the golf tee system 600, both the removable cap 615 and the top of the anchor cap 603 can each have a slot 610 to aid in the installation of the tee into the surface. The slot 610 allows a specific tool, such as those described herein or more generally, such as a coin, to be inserted into the slot 610 to assist in spinning the system 600 into the ground. The slot 610 can accept a device or object (e.g., a screwdriver, coin, finger, fingernail, spike wrench, or sports wrench) to secure the anchor 600 into the ground, such as by screwing, pushing, or twisting. The anchor 600 can include multiple slots 610. In additional examples, only the removable cap 615 or only the anchor top 603 has a slot 610 on its upper surface.

7A and 7B show cutaway views of tee system 700. In one example, anchor 700 is first inserted into the ground (or mat, if appropriate) with removable cap 715 installed. Tee 100 is then inserted into anchor 700 through removable cap 715. Ball height and tee height can be adjusted in the same manner as the systems described above. According to an embodiment of system 700, ball height _BH can be the distance from the bottom of cap 715 (i.e., where cap 715 contacts and rests on the ground surface) to the ball-contacting surface of the tee head when the tee is inserted into the anchor cavity. In such an embodiment, removable cap 715 contacts the ground surface at the same point as cap 702. In this way, the cap does not affect ball height _BH . Preferably, _BH should include the range from the USGA limit to just above the removable cap surface.

As shown, the removable cap 715 fits snugly over the top of the anchor cap 702. As explained above, the removable cap can engage a pin in the anchor cap 702. For example, the depicted slot 713 located on the underside of the removable cap 715 shown in FIG. 7B can accept a pin, which can then be locked into place by twisting the removable cap 715 relative to the anchor cap 702. In various embodiments, the removable cap can have a thickness of 0.08 inches (depicted by the opposing arrows in FIG. 7B). In additional embodiments, the removable cap can have a thickness of 0.03 to 0.25 inches. The total interior width of the removable cap can be 1.04 inches, but can also be between 0.50 and 1.95 inches. In terms of percentages, depending on the embodiment, the removable cap 715 can increase the total width of the system 700 by 5 to 20%. In alternative embodiments, the cap 702 may not include a flanged section as depicted. In such embodiments, the removable cap 715 may include a flanged section and may be thicker, resulting in a greater percentage of the total width, for example, up to or greater than 100%.

The removable cap 715 preferably has a centrally located hole 712 through which the tee 100 can pass. If, during use, the tee 100 breaks off at or near the top surface of the removable cap 715, the user can simply release the removable cap from the cap 702. When the removable cap 715 is removed, the broken portion of the tee is exposed and can be removed. In a preferred embodiment, this removal process is aided by the threaded portion 724 of the anchor 700, which does not extend into the removable cap 715. This allows the removable cap 715 to be easily removed from the anchor cap 702 without catching on the tee. In an additional example, the threaded portion 724 may not extend all the way to the cap 702, but instead can begin at the deepest part of the radius 718. The removable cap 715 also preferably has a radius bevel along its upper edge, which aids in comfort. In additional examples, the removable cap 715 can have dimpling, stippling, or textured side surfaces (portions perpendicular to the ground) that can aid in a user's grip. The removable cap can also include a fastener on its upper surface. For example, in a preferred embodiment, the upper surface includes a slot having a width of approximately 0.075 inches and a length of approximately 0.80 inches. The slot can also be cut at a radius 718, with the portion of the slot closest to the outer edge of the removable cap 718 being shallowest and the portion closest to the central hole 712 being deepest. Such an arrangement can be useful for accepting objects, such as coins, or specialized tools as described herein. In other examples, the slot 710 can be a constant depth. In additional examples, there can be more than one slot, for example, two slots arranged in an X or plus (+) pattern.

In one example, the ball height _BH is 86.12 mm. Therefore, having a penetration portion _P of 12.7 mm (i.e., the portion of the tee 100 that extends from the bottom of the cap 202 to the tip 106 of the tee 100; or, the portion of the tee 100 that is at and below the ground surface when the golf tee system 500 is inserted into the ground) provides a tee length _T of 98.82 mm. Alternatively, the penetration portion _P can be 3.175 mm, 6.35 mm, 9.525 mm, or more, thereby providing a tee length _T with a ball height _BH of 86.12 mm, 89.295 mm, 92.47 mm, 95.645 mm, or more. Moreover, the ball height _BH is not intended to be so limited. The ball height _BH can be at least 3.175 mm. Also, the ball height _BH can be adjusted based on the golfer's preferences. The total height of the system 700 without the cap can be 2.5 inches. In other embodiments, the total height T _H can be between 1.5 inches and 4 inches. The height T _H can be selected based on, for example, the surface condition. The diameter T _D of the external threads 708 can be, for example, 0.9 inches. In alternative embodiments, the diameter can be 0.4 inches to 2 inches based on the surface condition. For example, more aggressive threads 708 can be used in soft conditions to prevent unwanted ejection of the system 700 when struck. In harder conditions, smaller, less aggressive, or fewer threads 708 can be used. The anchor portion height A _H is also depicted as the length of the body portion before the sharpened point. This height can preferably be approximately 1.13 inches but can vary depending on the embodiment. For example, some embodiments can have significantly more threads 708 and therefore a much smaller point 706. In this situation, A _H will be much larger than depicted. The converse is also true; in some instances, fewer threads 708 can be used and A _H can be reduced, for example, from 0.25" to 2".

In a preferred embodiment, the tee will have threads along only a portion of its length, as depicted in FIG. 14 . Additionally, while the tee 100 is discussed as being threaded, the tee 100 need not be so limited. For example, the tee 100 could have detents, clips, bumps, indentations, or the like. The tee 100 can be height adjusted by a press fit or by engaging complementary holes, detents, or clips on the interior wall or surface of the anchor. Thus, an unthreaded tee can be pushed into or pulled out of the anchor to adjust the ball height _BH , although the pushing or pulling may require overcoming one or more forces (e.g., due to a press fit, clip, detent, etc.).

Figure 8 shows an exploded view of the components of tee system 800. In a preferred embodiment, tee system 800 is used with a standard artificial golf mat. In such an embodiment, a flanged portion 802 of base 801 is positioned beneath the artificial golf mat to hold system 800 in place. As shown, system 800 is comprised of multiple components. Base 801 includes flanged portion 802 and stem portion 807. The stem portion includes external threads 825 and internal threads 826. Another component, tee mounting stem 805, threads into internal threads 826 of base stem 807. Tee mounting stem 805 includes internal threads 827. The internal threads are configured to accept a tee through opening 820 (not shown). Tee mounting stem 805 also includes a flanged upper surface 812. Another component of tee system 800 is cap 804. The cap is installed over the top of the tee mounting stem 805. The inside of the cap 804 includes threads to accept the externally threaded portion 825 of the base 801. Another component of the system 800 is an optional, removable spacer 806. Any number of spacers 806 can be included. In a preferred embodiment, the system 800 is shipped with two spacers 806 included. The spacers 806 are placed between the upper portion of the base stem 807 and the underside of the flanged upper surface 812 of the tee mounting stem 805. When installed, the spacers 806 increase the effective height of the tee mounting stem 805 relative to the base 801.

FIG. 9 shows a cutaway view of a tee system 900. In the configuration shown, a cap 904 is seated and lowered onto a tee stem 905. The tee stem 905 is elevated by a single spacer 806. In such a configuration, the cap 904 is elevated from the base in view of the spacer 806. Three separate threaded portions are shown (904, 906, 907). The first threaded portion is between the cap 904 and the exterior side of the base stem 907. The second threaded portion is between the tee stem 905 and the interior of the base stem. The third is between a tee (not shown) and the interior of the tee stem 905. Additionally, although the tee is discussed as having threads and corresponding threads on the interior of the tee stem 905, the tee 100 and tee stem 905 need not be so limited. For example, the tee 100 and tee stem 905 can have detents, clips, bumps, indentations, or the like. The tee 100 can be adjusted in height by a press fit or by engaging complementary holes, detents, or clips on the inner wall or surface of the tee stem 905. Thus, an unthreaded tee can be pushed into or pulled out of the tee stem to adjust the ball height _BH , although the pushing or pulling may require overcoming one or more forces (e.g., due to a press fit, clip, detent, etc.).

The cap 804 of the system 800 preferably has a hole in its center. The hole facilitates insertion of the tee 100 into the tee stem 805. The hole 820 can be of various sizes, but is preferably large enough to at least allow the tee to pass through. In some embodiments, it may be beneficial for the hole 820 in the cap 804 to be as small as practical to prevent debris from entering the system 800. If, during use, a tee breaks off at or near the top surface of the cap, the user can simply release the cap 804 from the base stem 807. When the cap 804 is removed, the broken portion of the tee is exposed and can be removed. In a preferred embodiment, this removal process is aided by the threaded portion of the tee stem 807 that does not extend into the removable cap 804. In other words, the tee is not threaded into the cap 804.

Figure 10 illustrates the components of a tee system 1000. In one example of the system 1000, the base 1001 has a base flange 1002 with a diameter 1001D of approximately 2 inches. The diameter 1001D can vary depending on the embodiment. Preferably, the base flange 1002 has a diameter of at least 0.5 inches. In additional embodiments, the base flange has a diameter of at least 0.75 inches. In additional embodiments, the base flange has a diameter of at least 1 inch. In additional embodiments, the base flange has a diameter of at least 1.25 inches. In additional embodiments, the base flange has a diameter of at least 1.5 inches. In additional embodiments, the base flange has a diameter of at least 1.75 inches. In additional embodiments, the base flange has a diameter of at least 2.25 inches. In additional embodiments, the base flange has a diameter of at least 2.5 inches. In one embodiment of the invention, the base flange has a height of 0.137 inches. In a further example, the base flange has a height between 0.100 inches and 0.250 inches. In one embodiment of the invention, the base stem 807 has a height 1001H of 0.656 inches from the ground surface. In a further example, the base stem has a height of 0.250 inches to 1.0 inches from the ground surface. In one embodiment of the invention, the base stem has a diameter of approximately 0.630 inches. In a further example of the invention, the base stem can have a diameter 1001D of 0.33 inches to 1 inch. Preferably, the base stem is configured to fit within a hole in a standard artificial golf mat.

The system 1000 also includes a tee stem 1005. In one embodiment of the invention, the tee stem 1005 has a height 1005H of 0.75 inches. In additional examples of the invention, the tee stem can have a height of 0.25 inches to 1.5 inches. In one embodiment of the invention, the tee stem has a width 1005D at the threaded portion of 0.47 inches (corresponding to M12x1.5 threads). In additional examples of the invention, the tee stem can have a width at the threaded portion of 0.33 inches to 1 inch. In one embodiment of the invention, the tee stem includes an upper flanged portion. The upper flanged portion is preferably larger in diameter than the threaded portion of the tee stem. For example, the flanged portion can have a diameter 1005CD of 0.55 inches. In additional examples of the invention, the upper flanged portion can have a diameter between 0.34 inches and 1.01 inches. The height of the upper flanged portion is preferably 0.094 inches. In additional examples of the present invention, the height of the upper flanged portion of the tee stem can be between 0.065 inches and 0.250 inches.

The system 1000 also optionally includes a spacer 1006. In one embodiment of the present invention, the spacer 1006 has an outer diameter 1006OD of 0.550 inches and an inner diameter 1006ID of 0.472 inches. The outer and inner diameters preferably correspond to the diameter of the threaded portion of the tee stem and the diameter of the upper flange of the tee portion. Preferably, the spacer fits over the threaded portion of the tee stem, but cannot fit over the upper flanged portion of the tee stem. In one embodiment of the present invention, the optional spacer 1006 has a height 1006H of 0.188 inches. In additional examples of the present invention, the spacer 1006 can have a height of 0.100 inches to 0.500 inches.

The system 1000 also includes a cap 1004. In one embodiment of the present invention, the cap 1004 has a height 1004H of 0.71 inches. In additional examples of the present invention, the cap can have a height of 0.30 to 1.25 inches. Preferably, the cap 1004 is of sufficient height so that, with one or more optional spacers 806 installed, the lower edge of the cap 804 can engage the threads 825 on the outer portion of the base stem 807. In one embodiment of the present invention, the cap 1004 has a diameter 1004D of 0.69 inches. Preferably, the cap is of sufficient diameter so that it can engage with the base stem. In one embodiment, the interior wall 826 of the cap 804 has M16x1.5 threads. Other thread sizes and pitches may be used. In one embodiment of the present invention, the cap has a central bore with a diameter 1004ID of 0.31 inches. Preferably, the hole is large enough to allow a tee to pass through.

FIG. 11 illustrates various embodiments of the present invention 1100, 1101, and 1102, including two spacers, one spacer, and no spacer, respectively. Adding spacers changes the minimum height of the embodiment. For example, without spacers installed, embodiment 1102 has a height 1102H of 0.85 inches. With one spacer installed, embodiment 1101 has a height 1101H of 1.038 inches. With two spacers installed, embodiment 1100 has a height 1100H of 1.23 inches. As discussed above and depicted, the spacers are positioned between the upper side of the base stem and the lower portion of the tee stem flange. As such, the spacers elevate the tee stem relative to the base. This also elevates the cap 1104, as the cap sits on the tee stem flange 1105. The spacer 1106 is useful, for example, to control the height of the cap 1104 relative to the surface of the artificial mat. In some embodiments, it is preferable for the cap 1104 to remain below the surface level of the artificial mat, protecting it from direct hits. However, if the cap 1104 is too low, the tee may be more prone to tearing and may be more difficult to insert. The spacer 1106 can be added or removed to accommodate artificial mats of various thicknesses. For example, upon arrival at the driving range, a user can lift the artificial mat and install the system 1100 through a hole in the artificial mat. When the mat is placed back on the ground, the user can find that the cap is positioned sufficiently below the surface of the mat. The user can then lift the mat, remove the system 1100, remove the cap 1104 and tee stem 1105, and insert one spacer 1106 to arrive at the system 1101, or insert two spacers to arrive at the system 1100. The assembly is reconfigured by sliding the spacer over the threaded portion of the tee stem, then reassembling the tee stem into the base and reassembling the cap onto the tee stem.

In additional embodiments of the present invention, anchors, such as those described above, can be integrated directly into the practice mat. In this way, a golf driving range operator or other consumer can purchase a practice mat with the anchors already installed and only need to purchase a corresponding tee portion to provide further adjustments. In this embodiment, the anchor portion can differ from those described above in that the mat is integrated with a threaded component integrated therein. These threaded locations can be positioned at multiple points around the mat and can each accept a tee.
12A-12C illustrate a turf anchor installation tool 1200 according to an embodiment of the present invention. Tool 1200 is designed to engage with the various turf anchors described above, including 200, 300, 600, and 700. When installing a turf anchor using simple means, such as a coin, it can be difficult for a user to quickly determine the precise angle of insertion. Thus, once a tee is threaded into the anchor, the user can realize that the anchor has been installed at an awkward or undesired angle. The presently described tool solves this problem.

The installation tool 1200 is a single-piece tool. The tool has a lower radius 1205 that is configured to precisely engage the upper cap (removable or non-removable) of the various turf anchors described herein. The lower radius 1205 can take many shapes; for example, it can include two separate portions arranged as prongs along the radius, as shown, for example, in FIG. 13, such that the prongs can also be used as a conventional pitch mark repair tool.

According to various embodiments, the tool 1200 is tall enough to quickly indicate whether the anchor is driven into the ground in a square fashion. In a preferred embodiment, the tool has a height 1200H of approximately 2.30 inches. In additional examples, the tool is between 1.5 inches and 3.5 inches tall. Other heights are possible and within the scope of the present invention. The width 1207W at the base of the pad 1207 is approximately 1 inch. In alternative embodiments, the width is between 0.5 inches and 3 inches. The height of the pad is depicted as approximately 0.95 inches. The height of the pad can vary widely depending on the embodiment of the present invention. For example, in at least one embodiment, the central tee portion 1201 can simply have a radius portion 1205 at its base.

As shown, the tool includes wings 1203 that extend away from the central spine of the tool 1200. The wings provide sufficient grip for the user to spin the anchor into the ground. The width of the wings provides additional leverage. In various embodiments of the present invention, the width 1203W of the tool, from wing to wing, is approximately 1.5 inches. In additional examples, the wings may be narrower or wider, for example, 1 to 2.5 inches. In further embodiments, the wings may be absent altogether, and the center of the tool may be essentially cylindrical. In various embodiments, the thickness 1203T of the wings 1203 is approximately 0.7 inches. This thickness may be increased or decreased depending on the corresponding cap and slot arrangement. According to this embodiment, pads 1207 extend away from the central spine of the tool at points perpendicular to the wings. These pads provide increased, comfortable, and ergonomic support to the user.

The upper section 1201 of the tool 1200 can resemble a tee or include any other type of directional indicator to allow a user to quickly recognize whether the anchor is installed squarely. For example, with the tool 1200, when installing an anchor, a user can refer to the tee portion 1201 extending on the opposite side of the anchor to determine whether the anchor is installed squarely. If not, the upper tee portion will be positioned in a manner other than perpendicular to the ground. In some embodiments, both the tool 1200 and the anchor cap can be magnetic, allowing the tool 1200 to be attracted to the anchor, which makes it easier for a user to position the anchor when they go to install it in the ground.

Tool 1200 is designed to work in conjunction with the various embodiments of the anchor systems described herein and can form a component of systems that include those turf anchor systems.

Figure 13 shows an installation tool 1300 according to an embodiment of the present invention. It is a desire of the anchor systems described above to allow a user to maintain a consistent tee height regardless of where the user inserts the anchor. To achieve this, it may be preferable for the tee to remain inserted into the anchor portion at a fixed height, and then the anchor and tee system simply be transported from one location to another, for example, from one tee box to the next, or from a driving range to a course. To facilitate insertion of the anchor and tee system without disturbing the tee height, a user can utilize installation tool 1300.

The installation tool 1300 is configured to engage the anchor's cap (either non-removable or removable), allowing the user to spin the anchor into or out of the ground. To accomplish this, the tool 1300 has twin barbs 1302 at its lower, distal end. These barbs are configured to match the radius of the anchor's cap portion. In various embodiments, the barbs can be shaped to enable use as a ball mark repair tool.

Installation tool 1300 is further configured with a central channel 1305. Central channel 1305 is positioned outside of the midplane A of the barb. This allows tool 1300 to wrap around the tee by placing the tee into channel 1305, so that the tee does not obstruct access to the cap. In this way, tool 1300 can engage the cap portion of the anchor and can be used to install and remove the anchor in the ground without disturbing the tee height.

Tool 1300 also includes wings 1303 on each side, as shown. Wings 1303 provide ergonomic support for the user's hands and increase leverage between the user and the tool when the user is installing or removing an anchor. The tool can also be used to remove removable caps (if so equipped).

According to various embodiments, tool 1300 has a height 1300H of approximately 1.12 inches. The tool may be taller or shorter, for example, 0.5" to 2.5", depending on the use case and user. The width 1300W of wings 1303 may be approximately 1.5 inches from end to end. In various embodiments, the tool may be much narrower, for example, 0.5 inches wide (with little or no wings) or up to 2.5" wide. The extra width provides increased leverage for users needing additional assistance.

FIG. 14 shows five different tee embodiments (1400-1404) according to the present invention. The five embodiments depict different heights and thread depths. As shown, in various embodiments, the threaded portion may not extend all the way to the tee. 1400 has specifications of A=0.375 inches, B=1 inch, and C=1.375 inches. 1401 has specifications of C=2.125 inches and B=1.50 inches. 1402 has specifications of C=2.875 inches and B=1.50 inches. 1403 has specifications of C=3.625 inches and B=1.50 inches. 1404 has specifications of C=4 inches, B=2.0 inches, C _W =0.44 inches, C _H =0.10 inches, W=0.25 inches, TPI=5/16-18, and 220 degrees of Rad at the lower tip. In each example, the specifications are merely exemplary. Any component of one or more tees can be varied to be thicker or thinner, for example, to accommodate the thread pitch of the anchor system or to include more or fewer threaded portions.

Although particular elements, aspects, components, etc. are described in connection with one embodiment or example of an adjustable golf tee system, those elements, aspects, components, etc. may be included with other embodiments or examples of golf tees and golf tee mounting systems, for example, when so desired or advantageous.
