This invention relates to the sport of golf, and more particularly to a practice golf tee.
The standard golf tee, which consists of a wooden spike having a cupped upper end into which a golf ball rests, has been improved on in various ways in the prior art. One such improvement has been to device a golf tee that does not break when struck by a golf club, which is typical of the wooden golf tee. Various types of plastic tees having a rotatable or break-away cup have been devices, for example. Such prior art golf tees may be found in the following patents:
In these prior art patents, several designs for a golf tee that rotates down when struck by a golf club are evident. However, all of the prior art devices depict a tee that rotates down in only one rotational direction, providing zero feedback to the golfer as to the direction of his golf club or the angle of the face of the golf club at impact.
Several swing direction indicators exist in the prior art that incorporate a golf tee. For example, U.S. Pat. No. 2,712,939 to Harp on Jul. 12, 1955 teaches such a device, in which a golf tee is positioned centrally on a flat plate and a plurality of upright pegs are positioned around the golf tee. If the pegs are knocked down after a golf swing, the knocked-down pegs indicate that the golf club contacted the pegs in error and thus feedback is provided to the golfer. However, no feedback is provided in such a device to indicate the angle of the face of the golf club head at impact with the ball, even if the golf club was traveling properly straight. Moreover, the precise direction of the golf club at impact is not clearly indicated by such a device, the pegs only being able to provide feedback that the club was traveling from left-to-right or from right-to-left, in a somewhat digital indication. The embodiment of
Another example of such a direction-indicating device is taught in U.S. Pat. No. 3,018,109 to Starck on Jan. 23, 1962. In this device, a golf tee is positioned between several pegs that are positioned upright, and which terminate at a lower end in a ball and socket swivel. Such a device, as with the Harp device, does not indicate the club head angle at the point of impact with the ball. Further, this type of device does not indicate the direction of the club if it varies widely from the aligned pegs. Moreover, this type of product cannot be used on a golf course or with existing practice mats, since it is too large. Moreover, if the golf ball strikes one of the pegs itself, not only can the trajectory of the golf ball be affected, but an incorrect reading of the peg may result.
Therefore, there is a need for a device that will indicate the club head angle and direction of club head travel upon impact with a golf ball. Such a needed device would take the place of a conventional golf tee, and would not require special practice mats or the like. Such a device could also be used during a regular game of golf, perhaps not within the rules of professional golf but certainly from a practical standpoint and during practice games. Such a needed invention would not interfere with the travel of the golf ball itself or provide inaccurate indication of club direction or club angle from impact with the golf ball itself after impact. Further, such a needed device would be inexpensive to manufacture and easy to use, and would provide for a variety of golf ball tee heights. The present invention accomplishes these objectives.
The present device is a golf training tee for a golfer to use with a golf ball and a golf club. The tee includes a tee riser that has at a top end a cup adapted for receiving the golf ball thereon. A bottom end of the tee riser includes a substantially spherical ball member.
A base has a socket at a top end thereof that is adapted for pivotally receiving the ball member of the tee riser therein. The socket has an open portion on a front side thereof, the open portion including a substantially flat stop surface. The socket may impart a frictional force on the ball member sufficient to stop the ball member from moving within the socket when less than one ounce of force is applied tangentially to the top end of the tee riser, for example. As such, the ball member is not free to move around within the socket by gravity or other casual, minor forces.
In one embodiment, the socket may include a plurality of resilient socket walls mutually unattached at sides thereof, such that the socket walls may flex momentarily outward to allow insertion, removal, and movement of the ball member of the tee riser therein or therefrom. As such, the golf training tee of the present invention may include one or more tee risers, each having a mutually unique height.
The base includes at a lower end thereof a ground attachment member, such as a spike adapted for insertion into a ground surface, or a flat disk adapted for resting on the ground surface.
In use, when the golf ball is struck with the golf club, the tee riser pivots downwardly in a direction of the golf club at impact therewith. The tee riser stops its downward pivot at the stop surface of the socket, remaining pointed in the direction. As such, the golfer has an indication of the direction of the golf club at impact, providing educational feedback to the golfer. The golfer has additional motivation to look at the tee after impact, helping to keep his head down during his swing of the golf club, which promotes a better form and swing.
The present invention indicates the club head angle and direction of club head travel upon impact with a golf ball. The present device takes the place of a conventional golf tee, and does not require special practice mats or the like, although the present invention may be used with conventional practice mats. Further, the present invention may be used during a regular practice round of golf, as it does not interfere with the travel of the golf ball itself or provide inaccurate indication of club direction or club angle from impact with the golf ball itself after impact. Further, the present device is inexpensive to manufacture and easy to use, and provides for a variety of golf ball tee heights. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
