ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to golf tees and more particularly to such a tee which is adapted for positioning in the ground with its ball seat a predetermined height above the ground.
2. Description of the Related Art
Golf tees are generally positioned in the ground with their ball seats at an arbitrary height above ground level. There generally is no positive device on the tee for fixing this position. For proper striking of the ball by the golf club head, there is an optimum height above ground level for each club and each golfer. While an expert golfer usually has learned how to set the height of the tee, this is difficult to do for the less experienced golfer. The device of the present invention solves this problem by providing a golf tee or set of golf tees which can readily be set in the ground with their ball seats at predetermined heights above the level of the ground.
SUMMARY OF THE INVENTION
The device of the present invention is an improvement over the prior art in that it provides a golf tee or set of golf tees which are adapted so they can readily be set in the ground with their ball seats at an optimum height above ground level for each golf club and golfer.
This improvement is achieved by providing a collar on the golf tee which forms a stop when the tee is placed in the ground to set the golf seat of the tee at a predetermined height above ground level. The position of the collar on each tee provided is set for optimum striking of the ball for each golf club and each golfer.
A modified version of the device of the invention achieves the desired end result using only a single tee with a set of extension pieces which enables positioning of the ball seat at various different heights above ground, as may be desired. The extension pieces have a tee seat for the ball on one end and a pin on the other end which fits into a hole in the ball seat of the tee.
It is therefore an object of this invention to provide an improved golf tee which is adapted to be set with its ball seat a predetermined height above ground.
It is a further object of this invention to provide a golf tee which facilitates the striking of a golf ball in an optimum manner.
Other objects of the invention will become apparent in view of the following description taken in connection with the accompanying drawings.
