TETHERED GOLF TEE
A tethered golf tee includes a golf tee connected to a clamp via a flexible cord or string. During use, the tee is inserted into the ground for supporting a golf ball, and the clamp is positioned on the ground adjacent the tee. When the ball is struck, the clamp, tethered to the tee, prevents the tee from travelling too far, and facilitates the location and retrieval thereof. During storage, curved jaws of the clamp are closed around and frictionally engage the shaft of a golf club, providing easy access for future use.
The present invention claims priority from U.S. Provisional Patent Application No. 61/987,609, filed May 2, 2014, which is incorporated herein by reference.
TECHNICAL FIELDThe present invention relates to a tethered golf tee, and in particular to a tethered golf tee that clamps onto a golf club shaft when moving from one tee box to the next.
BACKGROUND OF THE INVENTIONGolf tees, in one form or other, have been used to prop up the golf ball, almost since the invention of the game of golf. Almost as recently, people have been finding ways to ensure that their golf tees do not get lost, by tethering them to some type of weight or spike.
U.S. Pat. No. 2,159,893 issued May 23, 1939 to Hansen; and U.S. Pat. No. 4,336,940 issued Jun. 29, 1982 to Sprague disclose tethered golf tees in which a spike at the end of the tether cord is inserted into the ground to ensure the golf tee does not fly too far away and get lost. Unfortunately, these systems require additional time and effort to place the spike in the correct location, and necessitates the storage of a sharp spike in the golfer's pocket or golf bag resulting in damage to both. U.S. Pat. No. 4,114,878 issued Sep. 19, 1978 to Hammond; and U.S. Pat. No. 7,488,263 issued Feb. 10, 2009 relate to tethered golf tees with a simple weight on the end of the tether cord. While these systems avoid the sharp spikes of the former systems, they still require the storage of a bulky weight in the golfer's pocket or the constant storage and retrieval from the golfer's golf bag.
An object of the present invention is to overcome the shortcomings of the prior art by providing a tethered golf tee with a clamp on the end of the tether cord, which acts as a weight during use and enables the golf tee to be clamped to the shaft of the golfer's club when moving from one tee box to the next.
SUMMARY OF THE INVENTIONAccordingly, the present invention relates to a tethered golf tee and clamp assembly comprising:
a golf tee for supporting a golf ball above ground level;
a clamp including opposed first and second jaws biased together; and
a cord tethering the golf tee and clamp together;
wherein inner walls of the jaws include rounded or curved sections forming an oval or rounded opening sized for frictionally engaging shafts of golf clubs.
The invention will be described in greater detail with reference to the accompanying drawings which represent preferred embodiments thereof, wherein:
With reference to
Ideally, the clamp 3 is comprised of first and second lever arms 11 and 12, including first and second handles 13 and 14, respectively, spaced apart at one end of the clamp 3, pivotally connected to each other proximate the middle via a pin 15 or some other rotatable connection. The first and second lever arms 11 and 12 also include first and second jaws 16 and 17, respectively, spring biased together at the other end of the clamp 3. In the illustrated embodiment, a coil spring 18 is provided, wrapped around the pin 15, for spring biasing the jaws 16 and 17 together; however, any suitable form of spring biasing the jaws 16 and 17 together, including a material property of the lever arms 11 and 12 themselves, is within the scope of the invention. By manually applying opposed forces to the ends of the first and second handles 13 and 14, the biasing force of the spring 18 may be overcome, so that the jaws 16 and 17 may be forced apart for receiving the shaft of a golf club. Removing the forces on the first and second handles 13 and 14 enables inner opposing walls 19 and 20 of the jaws 16 and 17 to frictionally engage the shaft of the golf club.
Typically, golf clubs, such as a driver, include a shaft with a tapering diameter. The inner opposing walls 19 and 20 of the jaws 16 and 17, respectively, include rounded or C-shaped sections, whereby, in the closed position, the jaws 16 and 17 form an oval, circular or pear-shaped opening 21 for frictionally engaging the shaft of a golf club, e.g. at a section of a shaft with a relatively wider diameter. Ideally, the opening 21 includes a diameter larger than a section of the shaft with a relatively smaller diameter, whereby the outer free ends of the jaws 16 and 17 may be biased together enabling the opening 21 formed by the jaws 16 and 17 to totally encircle the shaft during initial engagement with the golf club shaft. The jaws 16 and 17 of the clamp 2 may then slide down the shaft until the diameter of the opening 21 matches the diameter of the shaft, thereby frictionally engaging the shaft and preventing further movement therebetween. In a preferred embodiment, the inner walls 19 and 20 include a plurality of rounded sections, with different radiuses of curvature suitable, forming adjacent oval or circular openings 21 and 22 for frictionally engaging golf clubs shafts of different radiuses, e.g. different brands of golf clubs and different numbered clubs in the same set.
As illustrated in
