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
.
FIG. 6
is a cross-sectional view of the golf tee with tactile height adjustment of the present invention
200
as taken along line

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
302
formed with a bore
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.
Referring now to
FIG. 8
, a perspective view of an alternative embodiment of the threaded stop is generally designated
320
. Threaded stop
320
is formed with a body
322
having a star shape and formed with a bore
324
having a single, 360-degree thread
326
.
FIG. 9
is a perspective view of another alternative embodiment of the threaded stop and is generally designated
330
. Threaded stop
330
includes a body
332
having an oblong shape and formed with a bore
334
having a single, 360-degree thread
336
.
FIG. 10
is a perspective view of yet another alternative embodiment of the threaded stop of the present invention and is generally designated
240
. Threaded stop
340
includes a three-dimensional body
342
shaped to depict a baseball, and formed with an axial bore
344
having a single, 360 degree thread
346
.
FIG. 11
is a perspective view of yet another alternative embodiment of the threaded stop of the present invention and is generally designated
350
. Threaded stop
350
includes a body
252
having a hexagonal shape and formed with a bore
354
formed with a single, 360 degree thread
356
. Body
352
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. Other shapes are fully contemplated herein and are considered within the scope of the present invention.
Referring now to
FIG. 12
, a perspective view of another alternative embodiment of the golf tee with tactile height adjustment of the present invention is shown and generally designated
400
. 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
