Description

FIELD OF THE INVENTION

The invention relates to a golf tee. More specifically, the invention relates to a golf tee that is height adjustable.

BACKGROUND OF THE INVENTION

Golf tees are generally used to support a golf ball as a golfer is hitting the ball. Golf tees generally comprise an elongate shaft having an upper head for supporting the ball, and a lower spike for inserting into the ground. In use, a golfer inserts the lower spike into the ground such that the tee remains upright, places a golf ball on the upper head, and hits the ball.
As is known to those of skill in the art, depending on the type of shot a golfer is hitting, and the personal preferences of the golfer, amongst other factors, it may be desirable to position the golf ball at different heights above the ground. With a standard golf tee, this is accomplished by adjusting how far the spike is inserted into the ground. Alternatively, several golf tees exist which comprise means for adjusting the height of the upper head relative to the ground.
U.S. Pat. No. 6,729,977 to Young et al discloses a height adjustable golf tee wherein the body of the shaft includes screw threads. A disc that has a flat lower surface is provided. The disc is screwed onto to the shaft to a position desired by the user, and may abut the top of the ground when the tee is inserted into the ground. Accordingly, the disc may be used to prevent the shaft from being inserted into the ground past a certain point.
U.S. Pat. No. 5,052,689 to Lettrich describes a similar height adjustable golf tee to Young et al, in which a disc is positioned on the shaft and sits on top of the ground to prevent the tee from being inserted further into the ground. In the tee of Lettrich, however, the shaft does not comprise screw threads, and the disc frictionally engages the shaft. Furthermore, the disc of Lettrich includes a tube that extends upwardly from the disc. The user may cut the tube to a desired height, such that when the tee is inserted into the tube, the upper head contacts the top of the tube and is prevented from being further inserted into the tube.
U.S. Pat. No. 5,672,122 to Strong describes a similar height adjustable golf tee to Young et al, in which a disc is positioned on the shaft and sits on top of the ground to prevent the tee from being inserted further into the ground. In the tee of Strong, however, the shaft comprises indentations rather than screw threads, and the user may place the disc in an indentation at a desired height.
United States Patent Application 2005/0130769 to Olsen describes a height adjustable golf tee comprising a cylindrical collar that is slid onto the shaft of the tee. Similar to Lettrich, the bottom of the collar sits on the ground and prevents the tee from being inserted into the ground past a certain point, and the top of the collar contacts the upper head of the tee and prevents the tee from being inserted into the collar past a certain point.
U.S. Pat. No. 7,086,972 to Bainbridge discloses a height adjustable golf tee holder that includes an inner sleeve for holding a tee, and an outer sleeve in which the inner sleeve is received. In use, a tee is inserted into the inner sleeve, which is longitudinally movable in the outer sleeve, and the entire assembly is inserted into the ground. The inner sleeve and the outer sleeve include complementary fasteners, such that the inner sleeve can be snapped into fixed positions within the outer sleeve, thus adjusting the height of the tee.
United States Patent Application 2006/0105859 to Thirkettle et al discloses a height adjustable golf tee device that is semi-permanently fixed in the ground, for use at a driving range. A hollow cylindrical housing is positioned in a pre-made hole in the ground and secured therein. The housing includes an interior cavity having screw threads. A tee is provided which has screw threads on the outer wall thereof. The tee is screwed into the housing until the upper head is at a desired height.
U.S. Pat. No. 6,942,583 to Syu describes a height adjustable golf tee that includes a spike for inserting into the ground, a supporting tube for holding a golf ball, and a connecting tube for connecting the spike and the supporting tube. The bottom of the connecting tube is joined to the top of the spike. The connecting tube includes ridges extending outwardly from the sidewalls thereof. The ridges are at different fixed heights along the sidewalls. In use, the user positions the supporting tube around the connecting tube, on a ridge that is at a desired height.

SUMMARY OF THE INVENTION

In one broad aspect, a height adjustable golf tee assembly is provided. The assembly comprises a longitudinally extending stabilization member. The stabilization member comprises an upper end having an opening, a ground-penetrating tip having an opening and configured to penetrate the ground, a cavity extending between the upper end and the ground-penetrating tip, and a ground abutment member spaced from the ground-penetrating tip. The assembly further comprises a tee member. The tee member comprises a ball-supporting head, and a shaft that is longitudinally movable in the cavity and positionable at a plurality of positions
An advantage of the golf tee assembly is that it may position a golf ball at relatively high distances above the ground. In particular, the use of a stabilization member that is elongate and configured to penetrate the ground provides enhanced support for the tee member. Thus, the tee member can be positioned such that the ball-supporting head is relatively high above the ground, and the tee member will not tilt or fall over.
A further advantage of the golf tee assembly is that the stabilization member may prevent or minimize the risk that the tee will become dislodged from the ground when a ball is struck by a golf club or during a practice swing.
A further advantage of the golf tee assembly is that when the tee member is inserted into the stabilization member to a given position, and the assembly is inserted into the ground until the ground abutment member contacts the ground, the ball-supporting head of the tee member will be at a corresponding preset distance from the ground. That is, a user may position the tee member at a desired position within the stabilization member, and the assembly may be used numerous times, and each time will support a golf ball at substantially the same height above the ground.
A further advantage of the golf tee assembly is that the ground abutment member minimizes the risk that the stabilization member will become over-inserted and/or lodged in the ground.
In accordance with one aspect of the present invention, there is provided a height adjustable golf tee assembly comprising:

- a) a longitudinally extending stabilization member comprising an upper end having an opening, a ground-penetrating tip having an opening and configured to penetrate the ground, a cavity extending between the upper end and the ground-penetrating tip and a ground abutment member spaced from the ground-penetrating tip; and,
- b) a tee member comprising a ball-supporting head and a shaft that is longitudinally movable in the cavity and positionable at a plurality of positions.

In one embodiment, the tee member comprises distance indicators provided on the shaft. The indicators may comprise a scale denoting or representing a distance from the ball-supporting head to the ground abutment member. Such an embodiment may be advantageous because the indicators will allow a user to preset and/or read the quantitative distance from the ball to the ground.
In another embodiment, the tee member is removably receivable in the cavity.
In another embodiment, the stabilization member has an inner wall defining the cavity, and the shaft has an outer wall, and the inner wall and the outer wall have mating screw threads. Such an embodiment may be advantageous because it will allow for fine adjustment of the position of the tee member within the stabilization member. Furthermore, it will allow for the position of the tee member relative to the stabilization member to be adjusted while the golf tee assembly is in the ground, without inadvertently moving or dislodging the stabilization member. In addition, it may minimize the risk that the position of the tee member within the stabilization member will be accidentally changed, for example by being bumped by a golf club.
In another embodiment, the stabilization member is sized to be positioned within a footprint of the ball-supporting head when the tee member is received in the cavity. In other words, all of the outer perimeter of the stabilization member is positioned below the ball-supporting head.
In another embodiment, the stabilization member has an elongate main body portion, and the ground abutment member of the stabilization member comprises a flange extending outwardly from an upper portion of the elongate main body portion.
In another alternate broad aspect, a height adjustable golf tee assembly is provided. The height adjustable golf tee assembly comprises a stabilization member and a tee member. The stabilization member comprises an elongate portion having an upper end, and a lower ground-penetrating tip. A cavity extends downwardly from an opening in the upper end, and an elongate threaded inner wall surrounds the cavity. The tee member comprises a ball-supporting head, a shaft having a threaded outer wall, and a terminal end distal to the ball-supporting head. The threaded inner wall and the threaded outer wall have mating threads, and the tee member is rotatably receivable in the cavity. Rotation of the tee member relative to the stabilization member results in longitudinal movement of the tee member relative to the stabilization member.
An advantage of the golf tee assembly is that it may position a golf ball at a relatively high distance above the ground. That is, because the stabilization member is elongate and configured to penetrate the ground, it provides support to and holds up the tee member. Thus, the tee member can be positioned such that the ball-supporting head is relatively high above the ground, and the tee member will not tilt or fall over.
A further advantage of the golf tee assembly is that the stabilization member may prevent or minimize the risk that the tee will become dislodged from the ground when a ball is struck by a golf club.
A further advantage of the golf tee assembly is that the mating screw threads of the inner and outer wall will allow for fine adjustment of the position of the tee member within the stabilization member. Furthermore, it will allow for the position of the tee member relative to the stabilization member to be adjusted while the golf tee assembly is in the ground, without inadvertently moving or dislodging the stabilization member. In addition, it may minimize the risk that the position of the tee member within the stabilization member will be accidentally changed, for example by being bumped by a golf club.
In accordance with this aspect of the present invention, there is provided a height adjustable golf tee assembly comprising:

- a) a stabilization member comprising an elongate portion having an upper end, a lower ground-penetrating tip, a cavity extending downwardly from an opening in the upper end and an elongate threaded inner wall surrounding the cavity;
- b) a tee member comprising a ball-supporting head and a shaft having a threaded outer wall and a terminal end distal to the ball-supporting head, the threaded inner wall and the threaded outer wall have mating threads, the tee member is rotatably receivable in the cavity
- whereby rotation of the tee member relative to the stabilization member results in longitudinal movement of the tee member relative to the stabilization member.

In one embodiment, the stabilization member comprises a ground abutment member. Such an embodiment may be advantageous because when the tee member is inserted into the stabilization member to a given position, and the assembly is inserted into the ground until the ground abutment member contacts the ground, the ball-supporting head of the tee member will be at a corresponding given distance from the ground. That is, a user may position the tee member at a desired position within the stabilization member, and the assembly may be used numerous times, and each time will position a golf ball at substantially the same preset height above the ground. Furthermore, the ground abutment member minimizes the risk that the stabilization member will become over-inserted and/or lodged in the ground.
In another embodiment, the tee member comprises height indicators that indicate a distance from the ball-supporting head to ground level when the stabilization member is positioned in the ground and the abutment member contacts the ground. Such an embodiment may be advantageous because the indicators will allow a user to preset and/or read the quantitative distance from the ball to the ground.
In another embodiment, the ground abutment member comprises a flange extending outwardly from an upper portion of the stabilization member.
In another embodiment, the ground-penetrating tip has an opening that is in communication with the cavity, whereby the terminal end of the tee member is extendible through the cavity from the upper and past the lower ground-penetrating tip.
In another embodiment, the ground-penetrating tip is configured for penetrating the ground.
In another embodiment, the tee member is removably receivable in the cavity.
In another embodiment, the stabilization member is sized to be positioned within a footprint of the ball-supporting head when the tee member is received in the cavity.
In another embodiment, at least a portion of the stabilization member is substantially cylindrical.
In another broad aspect, a method is provided for supporting a golf ball. The method utilizes a height-adjustable golf tee assembly. The height adjustable golf tee assembly comprises an elongate stabilization member and a tee member. The elongate stabilization member comprises an upper end having an opening, a lower ground-penetrating tip, a cavity extending from the opening into the stabilization member, and a ground abutment member spaced from the ground-penetrating tip. The tee member comprises a ball-supporting head and a shaft. The method comprises positioning the height adjustable golf tee assembly in the ground with the shaft inserted in the cavity and the ground abutment member adjacent the ground; and, placing a golf ball on the ball-supporting head of the tee member.
In another embodiment, the step of positioning the height adjustable golf tee in the ground comprises inserting the tee member into the stabilization member, adjusting a longitudinal position of the tee member relative to the stabilization member, and inserting the golf tee assembly into the ground.
In another embodiment, the method further comprises using height indicators on the shaft to position the ball-supporting head at a desired distance from the ground abutment member.
In another embodiment, the step of inserting the tee member into the stabilization member comprises rotating the tee member relative to the stabilization member.
In another embodiment the step of positioning the height adjustable golf tee assembly in the ground comprises inserting the stabilization member into the ground, and inserting the tee member into the stabilization member.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-4, a golf tee assembly 10 of the present invention is shown. Golf tee assembly 10 is height adjustable, thus allowing a user to position a golf ball 11 at a desired height. Golf tee assembly 10 comprises a stabilization member 12, and a tee member 14, which are longitudinally movable relative to each other, thereby allowing for height adjustment.
Stabilization member 12 is longitudinally extending. That is, stabilization member 12 comprises a portion, for example body portion 16, that is elongate. Body portion 16 may be of numerous shapes, including cylindrical, frustoconical, rectangular, or octagonal. In the preferred embodiment, body portion 16 is cylindrical.
In some embodiments, body portion 16 may have a length of between about 0.3 inches and about 3 inches, and an outer diameter of between about 0.2 inches and about 0.5 inches. However, persons of skill in the art will recognize that other dimensions are possible. In the preferred embodiment, body portion 16 has a length of 0.5 inches, and an outer diameter of 0.25 inches.
The upper end 18 of stabilization member 12 has an opening 20, into which tee member 14 is to be inserted. As used herein, the terms ‘upper end’ and ‘upper portion’ refer to the portion of stabilization member 12 that is at the top of stabilization member 12 when golf tee assembly 10 is in use and positioned in the ground. Opening 20 may be of any suitable size and shape that would allow tee member 14 to be inserted therethrough and fixed at a plurality of different positions. In some embodiments, for example, opening 20 may be circular, and have a diameter of between about 0.15 inches and about 0.25 inches. In the preferred embodiment, opening has a diameter of 0.2 inches.
The lower end 22 of stabilization member 12 comprises a ground-penetrating tip 24. As used herein, the term ‘lower end’ refers to the portion of stabilization member 12 that is at the bottom of stabilization member 12 when golf tee assembly 10 is in use and positioned in the ground. Ground-penetrating tip 24 may be of any configuration that facilitates lower end 22 to penetrate the ground. For example, in one embodiment, ground-penetrating tip 24 may be beveled. In another embodiment, ground-penetrating tip 24 may be saw toothed. In yet another embodiment, ground-penetrating tip 24 may comprise a flat or square edge, which may have a small enough wall thickness such that the flat edge may penetrate the ground. Preferably, lower end 22 has a narrower diameter then upper end 18 and, accordingly, ground-penetrating tip 24 may be a surface that extends inwardly. For example, ground-penetrating tip 24 may extend inwardly at an angle, or it may be curved.
Preferably, lower end 22 of stabilization member 12 comprises an opening 26. Opening 26 may be of any suitable size and shape that would allow tee member 14 to pass therethrough, as described herein with respect to opening 20. In other embodiments, lower end 22 of stabilization member 12 may be closed.
As shown in FIG. 5, stabilization member 12 comprises a cavity 28, which extends downwardly from upper end 18. Cavity 28 may extend to a point proximal to ground-penetrating tip 24, to ground-penetrating tip 24, and preferably all of the way to optional opening 26. Thus tee member 14 may be pass all of the way through cavity 28 or may be lodged only partway downwardly from upper end 18. Accordingly, in use, cavity 28 may partially or fully house tee member 14. That is, tee member 14 may substantially fill cavity 28, or may only partially fill cavity 28.
Cavity 28 may be of any suitable size or shape for housing tee member 14. In the preferred embodiment, cavity 28 is substantially cylindrical. Cavity 28 is defined by or surrounded by an inner wall 30. Inner wall 30 may be structured to engage or cooperate with tee member 14, as will be described further herein.
In some embodiments, stabilization member 12 preferably comprises a ground abutment member 32. Ground abutment member 32 serves to contact the ground when stabilization member 12 is inserted into the ground as exemplified in FIG. 3. Ground abutment member may be any member that will abut or contact the ground when stabilization member 12 is inserted into the ground past a certain point. In other embodiments, stabilization member 12 may not comprise a ground abutment member.
In the embodiments of FIGS. 1-5, ground abutment member 32 is a flange extending outwardly from upper end 18, preferably adjacent the top thereof. In alternate embodiments, ground abutment member 32 may be a bar, a cross, or a tube. Ground abutment member 32 may be spaced from ground-penetrating tip 24. In all such embodiments, ground abutment member 32 comprises a member that extends outwardly from elongate body 16 and has a lower surface 34 that abuts or contacts the ground when stabilization member 12 is fully inserted into the ground as exemplified in FIGS. 3 and 4.
In the exemplified embodiment, ground abutment member 32 extends outwardly from the upper end 18 of stabilization member 12. Alternatively, ground abutment member 32 may extend from a middle portion of stabilization member 12.
Referring to FIG. 2, tee member 14 comprises a ball-supporting head 36, and a shaft 38. Ball-supporting head 36 is at the upper end of shaft 38, and may be configured to support a golf ball. As such, ball-supporting head may comprise a cup, a ring, or a hollow hemisphere or any other design known in the art. Shaft 38 extends downwardly from ball-supporting head 36 and ends in terminal end 40, which is distal to ball-supporting head 36. In some embodiments, terminal end 40 may be configured to penetrate the ground. For example, terminal end 40 may be beveled, or conical. In other embodiments, terminal end 40 may be blunt, such as if cavity 28 does not extend to lower end 22 of elongate body 16.
Tee member 14 may be of various sizes, depending on the preferences of the user, or the particular shot being performed, for example. In some embodiments, shaft 38 may be between 1 inch and 4 inches in length, and between 0.1 inches and 0.25 inches in outer diameter, and ball-supporting head may be between 0.25 inches and 0.75 inches in diameter. In the preferred embodiment, shaft 38 is about 3 inches in length, and about 0.15 inches in outer diameter, and ball-supporting head is about 0.5 inches in diameter.
In use, shaft 38 is insertable, preferably removably insertable, into cavity 20 via opening 20, and is longitudinally movable in cavity 28, and positionable at a plurality of positions. In some embodiments, shaft 38 has an outer wall 40, which is configured to engage inner wall 30 when shaft 38 is inserted into cavity 28. For example, outer wall 40 and inner wall 30 may comprise mating screw threads 42, 44, and as such tee member 14 is rotatably receivable in cavity 28. In such an embodiment, shaft 38 may be inserted through opening 20 into cavity 28, and may be positioned by rotating tee member 14 relative to stabilization member 12. Rotation of tee member 14 relative to stabilization member 12 will result in longitudinal movement of tee member 14 relative to stabilization member 14. Thus, a user may insert tee member 14 into stabilization member 12, and position ball-supporting head 36 at a desired preset height relative to stabilization member 12 by rotating shaft 38. In an alternate embodiment, outer wall 40 and inner wall 30 may engage by friction. That is, shaft 38 and cavity 28 may be sized such that shaft 38 fits snugly within cavity 28, and will remain in a given position unless force is exerted by a user. As mentioned hereinabove, in some embodiments, the lower portion 22 of stabilization member 12 comprises an opening 26. In such embodiments, shaft 26 may be inserted into cavity 28 such that terminal end 40 extends through cavity 28 from opening 20 through opening 26.
In some embodiments, as shown in FIG. 1, shaft 38 of tee member 14 may comprise distance indicators 46. Such indicators may be printed, engraved, or embossed, for example, on shaft 38. In the preferred embodiment, indicators 46 may comprise a scale (e.g., in inches) denoting a distance from ball-supporting head 36 to ground abutment member 32. For example, in the embodiment of FIG. 1, the scale on shaft 38 indicates that ball-supporting head is 1.5 inches above ground abutment member 32. In use, such indicators may be advantageous because when the golf tee assembly 10 is inserted into the ground such that ground abutment member 32 contacts the ground, indicators 46 will indicate the distance from the ball-supporting head 36 to the ground. As such, when a user places a ball on ball-supporting head 36, the golf tee assembly 10 will indicate to the user that the ball is a particular distance, for example 1.5 inches, above the ground.
In some embodiments, stabilization member 12 may be sized to be positioned within a footprint of the ball-supporting head when the tee member 14 is inserted into cavity 28. That is, no portion of stabilization member 12 is of a greater diameter than ball-supporting head 36. As such, in some embodiments, stabilization member may be sized such that all portions thereof are of a smaller diameter than ball-supporting head 36. In other words, stabilization member 12 is positionable within a footprint of ball-supporting head 36.
In some embodiments, tee member 14 is removable receivable in stabilization member 12. That is, tee member 14 may be completely removed from stabilization member 12. Thus, for example, if tee member 14 is damaged, a user may replace the damaged tee member with a new tee member 14. Alternatively, if desired, a user may exchange a given tee member for another tee member of a different size.
Golf tee assembly 10 may be fabricated in a number of ways and from a variety of materials. In the preferred embodiment, tee member 14 and stabilization member 12 are fabricated from a molded plastic such as polypropylene. In some embodiments, all or a portion of golf tee assembly 10 may comprise a phosphorescent (i.e. glow-in-the-dark) material. For example, one or both of tee member 14 and stabilization member 12 may be fabricated from a molded plastic that is mixed with strontium aluminate.
A method for utilizing an embodiment of a golf tee assembly of the present invention will presently be described. As discussed hereinabove, in one embodiment, the golf tee assembly may comprise an elongate stabilization member, and a tee member. The elongate stabilization member may comprise and upper end having an opening, a lower ground-penetrating tip, a cavity extending from the opening into the stabilization member, and a ground abutment member spaced from the ground-penetrating tip. The tee member may comprise a ball-supporting head and a shaft.
In a first step, the user may position the golf tee assembly in the ground with the shaft of the tee member inserted in the cavity of the stabilization member and the ground abutment member adjacent the ground. The golf tee assembly may be assembled either before positioning the assembly in the ground, or after positioning the assembly in the ground. That is, the user may insert the shaft of the tee member into the cavity of the stabilization member, and then insert the tee member and the stabilization member into the ground, or, the user may insert the stabilization member into the ground, and then insert the tee member into the stabilization member.
The step of inserting the tee member into the stabilization member may involve placing the terminal end of the shaft of the tee member into the upper opening of the stabilization member, and directing the shaft into the cavity. In order to direct the shaft into the cavity, the user may rotate the shaft relative to the stabilization member to engage screw threads on the inner wall of the stabilization member and the outer wall of the shaft, or may press the shaft into the stabilization member, depending on the structure of the inner wall of the stabilization member and the outer wall of the shaft, as discussed hereinabove.
After or concurrent with inserting the tee member into the stabilization member, the user may adjust the longitudinal position of the tee member relative to the stabilization member. Such an adjustment will adjust the height of a golf ball positioned on the ball-supporting member when the golf tee assembly is in the ground. In some embodiments, the user may desire a golf ball to be at a particular distance from the ground. Such a distance may be 1.5 inches, for example. As such, the user may adjust the longitudinal position of the tee member relative to the stabilization member such that the ball-supporting head is at the desired distance, for example 1.5 inches, from the ground abutment member. The user may achieve a desired distance by approximating or “eyeballing” the correct distance, or the user may use height indicators provided on the shaft. In use, when the assembly is inserted into the ground, and a ball is placed on the ball-supporting head, the distance from the ball-supporting head to the ground abutment member will be substantially equal to the distance from the base of the ball to the ground. Thus a user may preset the golf tee assembly to position a golf ball at a desired distance from the ground.
In embodiments wherein the inner wall of the stabilization member and the outer wall of the shaft have mating screw threads, the user may make particularly fine adjustments of the height of the golf ball. For example, in some embodiments, one full rotation of the tee member relative to the stabilization member may result in a change in longitudinal position of about 1/16^thof an inch.
As previously mentioned, the golf tee assembly may be positioned in the ground such that the ground abutment member is adjacent to the ground. That is, a user may insert the stabilization member into the ground until the ground abutment member contacts the ground. When the ground abutment member contacts the ground, the user will feel increased resistance, which will indicate to the user that the stabilization member is in place. As previously mentioned, the stabilization member may be inserted into the ground with the tee member housed therein, or alone.
Subsequent to positioning the golf tee assembly in the ground, the user may wish to further adjust the longitudinal position of the tee member relative to the stabilization member. For example, as mentioned hereinabove, in some embodiments the user may position the tee member in the stabilization member and adjust the longitudinal position thereof prior to inserting the golf tee assembly into the ground. In such an embodiment, when the tee member has been inserted into the ground, the user may consider that the height (or longitudinal position) of the tee member relative to the stabilization member is either too high or too low. Thus, the user may further adjust the height of the tee member relative to the stabilization member, for example by rotating the tee member, or by pressing or pulling the tee member.
Embodiments of the golf tee assembly of the present invention may be advantageous because the user may adjust the height of the tee member relative to the stabilization member without removing the assembly from the ground. That is, because the stabilization member is insertable into the ground, the user may, for example, rotate tee member relative to the stabilization member to adjust the height thereof, and the stabilization member will stay in place. This may allow the golfer to more accurately position a golf ball at a desired height.
After the user has positioned the golf tee assembly in the ground, the user may place a golf ball on the ball-supporting head of the tee member. When the ball has been placed on the ball-supporting head, the user may consider that the ball is either too high or too low. As such, the user may again adjust the longitudinal position of the tee member relative to the base member. This may be done with the ball on the ball-supporting head, or if desired, the user may remove the ball from the ball-supporting head prior to the adjustment.
Embodiments of a golf tee assembly of the present invention may be advantageous because the user may position the golf ball at relatively high positions. That is, referring to FIG. 3, because the stabilization member is elongate and insertable into the ground, it will provide support to and hold up the tee member. Thus, the tee member may be positioned such that the terminal end is relatively close to ground level, and the stabilization member will prevent the tee member from tilting or falling.
When the user has positioned the golf ball on the golf tee assembly at the desired height, the user may proceed with hitting the ball. As is known to those of skill in the art, it is not uncommon for a standard golf tee to break or become dislodged when a golf ball supported thereon is struck by a golf club. A golf tee assembly of the present invention may be advantageous because, when the ball is hit, stabilization member may anchor the tee member in the ground, and may act as a brace for the tee member, thus preventing the tee member from breaking or becoming dislodged.
