Abstract
A golf tee with tactile height adjustment includes a cup formed to receive and retain a golf ball. From the underside of the cup, a continuously threaded shaft extends and is formed with a longitudinal flat portion. A stop is formed with a threaded bore having threads complementary to those threads formed on the threaded shaft. Extending outward from the flat portions of the shaft are tactile engagement posts formed to engage the threads of the threaded stop as it threads along the threaded shaft. The engagement posts provide for the self cleaning of the threads of the golf tee, and also provides a tactile response including a distinct resistance to rotation of the threaded stop when the stop contacts the tactile posts. More specifically, when the threaded stop is positioned on the shaft adjacent a engagement post, the rotation of the stop is more difficult than rotation at a position on the shaft having no engagement post. In this manner, the user may tactilely determine whether the positioning disc is adjacent a tactile engagement post or between tactile engagement posts.
Description




FIELD OF THE INVENTION




The present invention is related to golf equipment. More specifically, the present invention is particularly, though not exclusively, related to an improved golf tee having an adjustable height for placement of the golf ball for optimum contact by a golf club.




BACKGROUND OF THE INVENTION




Whether its competition between peers, or the desire to refine the game, golfing has become a popular pastime. Golfers are always in search of the perfect course, the perfect game, the perfect swing, the perfect clubs, or simply enjoying the outdoors. While the basic equipment for golfing continues to include a golf ball, golf club, and golf tee, the golfing industry has continuously made improvements to this equipment. However, despite the innovations in golfing equipment over the past years, the golf tee has remained substantially unchanged from the original wooden peg having a cup for receiving the golf ball, and improvements have been limited.




One such improvement is documented in U.S. Pat. No. 1,625,911 entitled “Golf Tee” which issued to H. L. Richards in 1926. This patent discloses a golf tee having a cup with a threaded shaft, and a positioning disc formed with a threaded bore sized to receive the threaded shaft. By rotating the positioning disc relative to the threaded shaft, the positioning disc may be advanced over the shaft thereby raising the effective height of the golf tee. More particularly, by rotating the positioning disc clockwise relative to the shaft, the positioning disc advances toward the head of the tee making the effective height of the tee smaller. On the other hand, by rotating the positioning disc counter-clockwise relative to the shaft, the positioning disc advances away from the head of the tee making the effective height of the tee greater.




The golf tee disclosed by Richards was a stark improvement over the wooden peg, and provided the golfer with the ability to adjust the height of the golf tee. However, because the threaded portion of the golf tee is inserted into the playing surface, or soil, the ability to adjust the height of the golf tee ceases after the first use because the threads are filled with soil. Thus, while the Richards' tee is adjustable, it is not re-adjustable due to the accumulation of soil in the threads.




Another improvement to golf tees is shown in U.S. Des. Pat. No. Des. 370,041 entitled “Adjustable Height Golf Tee”, which issued to C. A. Thomas in 1996. This patent discloses a golf tee formed with a series of partially circumferential notches formed along the golf tee shaft, and a positioning disc formed with a center bore having an internal tab insertable into the circumferential notches. By choosing which of the circumferential notches to place the tab, the effective height of the golf tee is determined. For instance, when the desired height of the golf tee is small, the positioning disc is positioned along the shaft and the internal tab is inserted into a notch closer to the head of the tee. On the other hand, when the desired height of the golf tee is large, the positioning disc is positioned over the shaft and the internal tab is inserted into a notch closer to the base of the tee.




Because there are only a limited number of notches formed in distinct locations along the shaft of the golf tee, the height of the Thomas tee is only adjustable to a limited number of positions. Also, as with the Richards tee, once the Thomas tee is inserted into the soil, the partial circumferential notches of the Thomas tee will fill with soil thereby decreasing the ability to re-adjust the height of the tee.




U.S. Pat. No. 5,672,122 entitled “Adjustable Golf Tee” which issued to P. G. Strong in 1997 discloses a golf tee having a shaft formed with a series of circumferential grooves, and a disc-like member formed with an offset internal aperture sized to receive the shaft, and formed with a smaller, central aperture which contacts the selected circumferential groove securing the disc-like member in place along the shaft. The disc-like member acts as a vertical stop to adjust the effective height of the golf tee.




Even though a number of circumferential grooves are formed along the shaft, the placement of the disc-like member is still limited to a handful of distinct positions. The disc-like member must be engaged into one of the circumferential grooves in order to set the height of the tee, and thus the golf tee is not continually adjustable along its entire length. Further, as with the other golf tees described above, the circumferential grooves will fill with soil on the first use, thereby complicating a second use of the tee with an different height.




U.S. Des. Pat. No. 413,640 entitled “Continuously Variable Height Golf Tee” which issued to W. P. Feurer III in 1999 discloses a golf tee having a threaded shaft, and a positioning disc formed with a threaded bore sized to receive the threaded shaft. The positioning disc is sized to have a diameter significantly larger than the diameter of the tee head for receiving the golf ball. Like the device disclosed in the '911 patent, by rotating the positioning disc relative to the threaded shaft, the positioning disc may be advanced along the shaft thereby raising the effective height of the golf tee. More particularly, by rotating the positioning disc clockwise relative to the shaft, the positioning disc advances toward the head of the tee making the effective height of the tee smaller. On the other hand, by rotating the positioning disc counter-clockwise relative to the shaft, the positioning disc advances away from the head of the tee making the effective height of the tee greater.




The Feurer patent discloses a device, which is very similar to the Richards device outlined above, including the threaded shaft and a positioning disc formed with a threaded bore. As with the Richards device, the threads of the Feurer device will become filled with soil once inserted into the playing surface, effectively fixing the height of the tee for future use.




Another deficiency in the Feurer golf tee is the inability to consistently position the tee at a particular height. For instance, a particular height may be determined to be optimum for a particular golf club being used. However, once the golf tee has been used, it is often damaged, thereby preventing its re-use. However, because the Feurer golf tee has no indicia for identifying height settings, it is virtually impossible to set the height of the new tee to the height of the damaged tee unless a precise measurement was taken. Such measurements are unlikely to be taken during the heated competition of a golf game, and thus, there will inevitably exist a difference in the effective height of the golf tee.




Another concern with current golf tees is the inability to adjust the device without looking at it closely. For example, in order to precisely set the device disclosed in the '122 and '041 patents, the golfer must closely examine the tee and position the disk in the proper groove or slot. Similarly, the devices disclosed in the '640 and '911 patents would require the golfer to take a measurement of the effective height of the golf tee, or count threads—neither of which is likely during a golf game. Coupling the requirement for a close visual examination of the golf tee with a golfer having far-sightedness, renders the current adjustable golf tees little improvement over the wooden peg golf tee.




While there have been a number of “adjustable” golf tees introduced to the marketplace, none truly remain adjustable following its first use. Also, while many golf tees have been touted as an adjustable tee, many are not continuously adjustable along the length of the shaft of the tee, and instead provide only a handful of fixed-height options.




In light of the above, it would be advantageous to provide a golf tee that is continuously adjustable along the entire length of the shaft. It would also be advantageous to provide a golf tee that is initially adjustable, and remains easily adjustable following removal from the soil of the playing surface. It is also advantageous to provide a golf tee having the ability to consistently set the height of the tee, regardless of use or re-use, and without the requirement for close visual examination by the golfer.




SUMMARY OF THE INVENTION




The golf tee of the present invention includes a cup formed to receive and retain a golf ball. From the underside of the cup, a continuously threaded shaft extends and is formed with a longitudinal flat portion. A stop is formed with a threaded bore having threads complementary to those threads formed on the threaded shaft. Extending outward from the flat portions of the shaft are tactile engagement posts formed to engage the threads of the threaded stop as it threads along the threaded shaft.




The engagement posts provide for the self-cleaning of the threads of the golf tee, and also provides a tactile response. There is a distinct resistance to rotation of the threaded stop when the stop contacts the tactile posts. More specifically, when the threaded stop is positioned on the shaft adjacent a engagement post, the rotation of the stop is more difficult than rotation at a position on the shaft having no engagement post. In this manner, the user may tactilely determine whether the positioning disc is adjacent a tactile engagement post or between tactile engagement posts.




By introducing the positioning disc to the end of the shaft opposite the cup, the golfer may begin rotating the positioning disc about the shaft thereby advancing the positioning disc toward the cup. Due to the tactile feedback provided by the tactile engagement post, the golfer may determine the exact position of the threaded stop along the shaft simply by counting the number of tactile posts that have been passed. As a result of this purely tactile height setting, a golfer having little or no near-sightedness can easily, accurately, and repeatably set the height of his or her golf tee.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT




Referring initially to

FIG. 1

, an exploded perspective view of the golf tee with tactile height adjustment of the present invention is generally designated


100


. Golf tee


100


includes a head


102


formed with a ball-receiving cup


104


, and a shaft


106


extending downward from the head and formed with threads


108


. Shaft


106


is also formed with a flat portion


110


having a series of engagement posts


112


A,


112


B,


112


C and


112


D. Shaft


106


of golf tee


100


ends in a tapered point


114


to facilitate the placement of shaft


106


into the playing surface, namely, grass-covered soil.




The golf tee with tactile height adjustment


100


of the present invention also includes a stop


116


formed with a threaded bore


118


sized to receive threaded shaft


106


. When the stop


116


is advanced in direction


120


, and rotated in direction


122


(shown in FIG.


2


), the stop


116


advances along threaded shaft


106


.




As shown in

FIG. 1

, a plurality of indicia


11




3


are formed or printed on shaft


106


to provide a visual marker for the positioning of the threaded stop


116


along the threaded shaft


106


. In a preferred embodiment, indicia


113


may include numbers, such as the numbers 1, 2, 3, 4, and 5 as shown, or other indicia may be used.




Referring now to

FIG. 2

, a perspective view of the golf tee with tactile height adjustment of the present invention


100


is presented showing stop


116


threadably engaged on shaft


106


. As shown in this Figure, stop


116


has been positioned such that threaded bore


118


receives shaft


106


and is rotated in direction


122


to advance the stop


116


in direction


120


toward head


102


.





FIG. 3

is a cross-sectional view of the golf tee with tactile height adjustment of the present invention


100


as taken along line


3





3


of

FIG. 2

, and showing the threaded shaft


106


encircled by the threaded stop


116


, with the engagement post


112


extending perpendicularly from the flat portion


110


of the threaded shaft


106


to engage the threads


118


of the threaded stop


116


thereby providing tactile resistance to a threaded stop


116


as the threaded stop


116


is rotated along the threaded shaft


106


in direction


122


.




Continuously Variable Tee Height




The position of stop


116


on shaft


106


defines a tee height


122


as shown in FIG.


2


. Tee height


122


is the distance between the lower surface of stop


116


, and the upper surface, or cup


104


, of head


102


. It is to be appreciated that any tee height


124


may be established by rotating stop


116


in direction


122


thereby advancing the stop


116


toward head


102


to shorten the tee height


124


, or away from head


102


to lengthen the tee height


124


. Because there are no set positions for stop


116


, a tee height


124


may be established along the entire length of the shaft


106


ranging from a very short tee when the stop


116


is adjacent head


102


, to a very tall tee when the stop


116


is on threaded portion


109


adjacent pointed end


114


.




Tactile Feedback Corresponding to Tee Height




As stop


116


is positioned over tapered point


114


, threaded bore


118


engages threads


108


of shaft


106


. As stop is rotated in direction


122


, such as clockwise for a standard threaded shaft


106


, stop


116


advances along shaft


106


in direction


120


. As stop


116


passes from the lower threaded portion


109


to the portion of shaft


106


having flat portions


110


, the surface area of contact between the threaded shaft


106


and the threaded bore


118


decreases by approximately twenty five percent (25%).

FIG. 3

clearly shows this decreased surface area of contact. The decrease in surface area of contact corresponds to a decrease in the rotational friction experienced by the golfer as he or she is rotating the stop


116


along shaft


106


. As a result, the golfer may determine tactically where along the shaft


106


the stop


116


is positioned.




As the stop


116


continues to be rotated in direction


122


, stop advances in direction


120


toward head


102


. When stop


116


passes over engagement post


112


, the surface area of contact increases due to the contact of the engagement post


112


to threads


118


. More specifically, engagement post


112


has a length such that engagement post height


128


is the same as threaded shaft radius


126


resulting in the engagement post physically contacting threads


118


of stop


116


. This increased friction provides the golfer with tactile feedback acknowledging positioning of the stop


116


over the first engagement post


112


A.




By continuing the rotation of stop


116


in direction


120


and


122


toward head


102


, stop


116


passes over engagement post


112


B, and may be continued all the way to head


102


, with tactile feedback providing information to the golfer as to the particular tee height


124


. Using this method for establishing tee height


124


, the golfer may set or adjust the tee height


124


without visually confirming the proper setting. This feature is particularly useful when the golfer cannot see the golf tee well, such as golfers suffering from far-sightedness.




While

FIGS. 1 through 3

depict a golf tee formed with four engagement posts


112


A,


112


B,


112


C, and


112


D, it is to be appreciated that shaft


106


may be formed with any number of engagement posts. For instance, ten (10) engagement tabs


112


may be formed along shaft


106


to provide tactile feedback to the golfer for ten distinct tee heights


124


.




Engagement posts


112


have been shown with a diameter


130


, and stop


116


has been shown with a height


132


. In a preferred embodiment, diameter


130


may be less than height


132


in order to optimize the self-cleaning aspects of the present invention. Alternatively, diameter


130


may be equal to or larger than height


132


.




Self Cleaning Reusable Golf Tee




One of the primary challenges to using currently available adjustable golf tees is the fact that they are not practically reusable because soil becomes trapped in the other tees. The golf tee with tactile height adjustment of the present invention


100


is self-cleaning. The self-cleaning nature of the present invention is achieved by two primary features, alone or in combination.




The first feature providing for the self cleaning of the golf tee with tactile height adjustment of the present invention


100


is the flat portion


110


. As stop


116


is rotated in direction


122


, any soil that is trapped in threads


108


becomes un-trapped when passing over flat portion


110


. As a result, any soil that would damage other golf tees will be easily removed from the golf tee with tactile height adjustment of the present invention


100


as the soil passes over the flat portion


110


.




The second feature providing for the self cleaning of the golf tee with tactile height adjustment of the present invention


100


is the engagement post


112


passing through threads


118


of stop


116


as it rotates past the engagement post


112


during the adjustment of the tee height


124


. More specifically, as the engagement post


112


passes through threads


118


, any soil remaining in threads


118


are removed.




As a result of the self cleaning nature of the golf tee with tactile height adjustment of the present invention


100


, the tee may be set for a particular tee height


124


, inserted into the playing surface (soil) for use, and then removed and the tee height


124


may be adjusted for the next use without excessive friction, or resistance due to soil-fouled threads.




An Alternative Embodiment of the Present Invention




Referring now to

FIG. 4

an exploded perspective view of an alternative embodiment of the golf tee with tactile height adjustment of the present invention is shown and generally designated


200


. Golf tee


200


includes a head formed


202


with a ball-receiving cup


204


, and a shaft


206


formed with threads


208


and extending downward from the head


102


and formed with a flat portion


210


having a series of engagement tabs


212


A,


212


B,


212


C, and


212


D.




The golf tee with tactile height adjustment


200


of the present invention also includes a stop


216


formed with a threaded bore


218


sized to receive threaded shaft


206


. When the stop


216


is advanced in direction


220


, and rotated in direction


222


(shown in FIG.


5


), the stop


216


advances along threaded shaft


206


.




Referring now to

FIG. 5

, a perspective view of the golf tee with tactile height adjustment of the present invention


200


is presented showing stop


216


threadably engaged on shaft


206


. As shown in this Figure, stop


216


has been positioned such that threaded bore


218


receives shaft


206


and is rotated in direction


222


to advance the stop


216


in direction


220


toward head


202


.




In a preferred embodiment, each engagement tab


212


has a thickness


226


, and the stop


216


has a height


228


. In order to facilitate the removal of dirt from golf tee


200


, thickness


226


may be less than height


228


. Alternatively, thickness


226


may be equal to or greater than height


228


.

of

FIG. 5

, and showing the threaded shaft


206


encircled by the threaded stop


216


, with the engagement tab


212


extending perpendicularly from the flat portion


210


of the threaded shaft


206


to engage the threads


218


of the threaded stop


216


thereby providing tactile resistance to a threaded stop


216


as the threaded stop


216


is rotated along the threaded shaft


206


in direction


222


.




As with the golf tee with tactile height adjustment of the present invention


100


, alternative embodiment


200


also provides the same continuously variable tee height, and tactile feedback corresponding to tee height, and also provides for the self-cleaning of the golf tee


200


during use.




Referring now to

FIG. 7

, a perspective view of an alternative embodiment of the threaded stop is shown and generally designated


300


. Threaded stop


300


includes a body

304


having a single,


360


degree thread


306


which provides a stop which is self-cleaning and resistant to fouling by the accumulation of soil on the threaded portion of the threaded shaft (not shown this Figure). In use, the rotation of stop


300


in direction


308


advances the threaded stop


300


along the threaded shaft. Because thread


306


has only one revolution (360 degrees), soil that has accumulated on the threaded shaft is easily removed as the threaded stop


300


is advanced. The single thread


306


, coupled with the flat portion


110


having a series of engagement posts


112


A,


112


B,


112


C and


112


D as discussed in conjunction with

FIG. 1

, provide an a golf tee having superior functionality and reuse.

may be embossed or imprinted with indicia, such as text


358


and/or artwork


360


to provide a novelty item having a particular focus, such as advertisement or promotional purpose, of featuring a proprietary logo.




It is to be appreciated, however, that while threaded stops shown in

FIGS. 7-11

have been formed with a single, 360 degree thread, continuous threads are contemplated, and may be substituted in threaded stops


300


,


320


,


330


,


340


and


350


without departing from the present invention. It is also to be appreciated that while a threaded stops depicted herein include a variety of shapes, such presented shapes are not intended to be limiting, rather, merely exemplary of preferred embodiment.

. Golf tee


400


includes an enlarged head


402


formed with a ball-receiving cup


403


, and a threaded shaft


404


extending downward through a threaded stop


406


. Enlarged head


402


is formed with a first diameter


408


, and threaded stop


406


is formed with a smaller diameter


410


.




From

FIG. 12

, it is to be appreciated that the diameter


410


of the threaded stop


406


may be different than diameter


408


of head


402


. More specifically, although various size relationships between the threaded stop


406


and the head


402
