1. Field of the Invention
The present invention relates to a golf apparatus and equipment used in playing the game of golf on a golf course or practicing golf on or off the golf course and more specifically is directed to a new and improved golf tee which is extremely stable when inserted into the ground and allows a golf ball to be driven off the tee with a minimum of interference between the golf tee and the golf ball.
2. Description of Prior Art
Golf tees have been available in numerous designs shapes and sizes and have been used in playing the game of golf for a substantial period of time. Golf tees are permitted under the rules of play for golf by the United States Golf Association and the Royal and Ancient Golf Association. The purpose of using the tee in playing the game of golf is to raise and support the golf ball off the ground when driving or otherwise hitting the golf ball from the teeing area on a golf course or on a practice range. It is believed that the utilization of a tee from the teeing area on a golf course was allowed by those who make the rules governing play because the grass appearing in and around a teeing area on a golf course is dissipated as a result of the continued use thereof by the players whereas the remainder of the golf course is initially covered with grass which provides a soft lie for the golf ball so that it may be struck and the lie would not usually impart undesirable characteristics to the flight of the golf ball.
The flight of the golf ball is dependent on certain factors such as the height in which the ball is teed off the ground, back spin imparted to the ball, wind conditions and dimple construction on the ball itself It has now been recognized that the interaction between the golf ball and the tee which supports the golf ball can impart undesirable characteristics to the flight of the ball. For example, most tees have conventionally been made of solid wood with a circular shaped cup top supported by a stem that is inserted into the earth. It is very difficult to always tee the golf ball at exactly the same height from the surface of the earth for a particular club that is being utilized. This has become even more difficult as the length of tees has increased because of the larger size of the golf club heads, particularly for drivers. In addition, the concavity of the standard tee allows for a substantial amount of surface contact between the tee and the ball. The friction between the ball and the concave surface will prematurely impart a spin to the ball and it is usually an undesirable spin. This spin may be accelerated by natural wind conditions in existence at the time of play. It is well known that the golf ball flight can be determined in part by the initial spin which is imparted to the ball at the time of contact. It is therefore desirable for the ball to have limited contact with the tee to mitigate the undesirable spin conditions. In addition, as the golf club head approaches the impact area it generates a great deal of wind which may cause initial undesirable movement of the golf ball before impact. Various golf tees have been developed in an attempt to overcome this undesirable feature of the golf tee. Examples, of such tees are those which utilize a plurality of bristles extending from the head of the golf tee upon which the golf ball rests. In other instances, there is provided a golf tee having a central stem with three fan shaped flutes extending vertically upwards ending in a point shaped vertice for holding the golf ball. An additional embodiment of prior art golf tees includes a tapered spike made of rigid plastic material with a head. A rotatable collar is secured to the head and supports a plurality of finger like elements constructed from a semi-rigid plastic material. The collar can rotate on the head and is designed to support the golf ball. These prior tees are subject to wear and they either break when struck by the golf club or after extended use the bristles become so flexible that they can no longer adequately support the golf ball or it is not possible to cause the golf ball to be teed at exactly the same height each time a particular club is utilized.
SUMMARY OF INVENTIONAn improved golf tee having a stem constructed of rigid plastic material terminating in a pointed tip adapted to penetrate the earth and having a second end terminating in a head shaped member. A golf ball supporting member of a flexible plastic material is permanently secured to the head shape member of the stem and the golf ball supporting member includes a plurality of upwardly directed extensions constructed of flexible plastic material arranged to support the golf ball.
In accordance with a more specific aspect of the present invention, the golf ball supporting member is over molded and permanently secured to the head shaped member of the stem.
In accordance with a further aspect of the present invention, the upwardly directed extensions of the golf ball support member include three tooth shaped extensions flared outwardly from the stem each of which terminates in a tip which is utilized to support the golf ball.
In accordance with a further aspect of the present invention, the upwardly directed extensions of the golf ball supporting member include a plurality of spaced apart fingers disposed peripherally about the head shaped end on the stem.
The golf tee of the present invention is constructed of molded plastic material and provides a plurality of points of contact at the distal ends of upwardly directed flutes or fingers which are spaced apart so that they support a golf ball. The spaced apart feature of these upwardly extending members provides an open space beneath the golf ball which insures that the gust of air created by the approaching club face will not prematurely set the ball in motion. In addition, by utilizing the points of contact at the distal ends of the upwardly extending members minimal contact is provided between the ball and the tee, thus eliminating the undesirable spin which may otherwise be imparted to the golf ball by the contact of the ball with the head of the tee. The tee of the present invention may have a plurality of heights which allow the utilization of the tee with various golf clubs including the large headed drivers that are currently in existence and favored by many golfers.

As is shown more clearly in
In accordance with a preferred embodiment of the tee of the present invention the ball support member 30 is constructed from polyurethane plastic material. Depending upon the height of the upwardly directed extensions or fingers of the ball support member the hardness ranges between 60 and 90 durometers as measured on the Shore scale A. The shorter fingers 48 as shown in
In accomplishing the over molding the ball support member 30 is constructed preferably by injection molding which allows the polyurethane plastic material to extend downwardly and wrap around the outwardly extending radial flange 18 as is illustrated at 50 in
Referring more particularly to
The ball support member 70 includes upwardly directed extensions which in the presently preferred embodiment include three tooth shaped members 72, 74 and 76 which terminate at their distal ends 78, 80 and 82 in points or tips. As shown, the distal ends 78, 80 and 82 are flared outwardly from the longitude axis of the stem 62 in such a manner that the golf ball is supported only at the tips of the distal ends 78, 80 and 82 of the tooth shaped members. This provides minimal contact between the golf ball and the tee thus providing minimal disturbance of the flight of the golf ball from the tee. It is also noted that by flaring the tooth shaped members 72, 74 and 76 radially outwardly from the longitude axis of the stem 62 space is provided underneath the golf ball and the between the upwardly directed extensions to provide for the movement of air as generated by the movement of the driver head toward the golf ball so that this additional air does not interfere with the golf ball by moving it prior to being struck by the driver head.
As shown in
As shown more particularly in
It should also be noted that the outer surface 88 of the tooth shaped extensions 78, 80 and 82 for the ball support member have an outer surface which is contiguous with the outer surface 90 of the stem 62.
