DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to a golfing aid for improving the capacity of a player to correctly execute the swing of a golf club.
A golf club during a swing should be maintained to move through an arc, starting at the address position (bottom of the stroke) and moving upwards during the backstroke to its top position and then downwards during the downswing to strike the golf ball and again upwards during the follow-through. This swing should be carried out with the club held firmly in the two hands of the player, with the player leaning forward and swinging his body during the major portion of the stroke to cause the head of the club to follow the correct arc. During this process the leading arm generally plays the role of acting as the guide for the path of the club so that the swing of the leading arm directs the path of the club, whereas the lagging arm plays a lesser role in maintaining the path of the golf club and a greater role in propelling the club.
During the swinging motion the club is turned about the axis of its shaft in one direction on the upward movement and in the reverse direction on the downward movement and it will thus be realised that it is highly important to be able to control not only the swing of the club in the arc, but also its rotation about the shaft axis as it moves through the arc in both the upward and downward swing. At the time that the head strikes the ball, the club must be accurately positioned to propel the ball in the required direction.
It has been long recognised that the swing of the golf club is one of the critical factors of a consistent performance, and a great deal of experimentation has taken place to analyse the faults of individual players and to provide an aid to assist in the improvement of a golf swing. A great number of devices have been constructed ranging from complex and large structures including robotic arms to assist in guiding the swing of the player, or hoops to guide the head of the golf club in the correct arc. Each of these methods and apparatuses are directed at certain aspects of the swing and assist to varying degrees in improving the swing.
Many of the larger, complex devices suffer the fault of inconvenience of use, a large requirement of storage space and also expense, and are usually unaffordable to the majority of golf players because of the high cost.
A number of smaller devices have also been suggested each focussing on specific aspects of the position of the golf club relative to the body of the player. The present invention is one of several that is related to a guide member that attaches to or is made as part of the shaft of a golf club and which gives an indication of the quality of the swing by its position relative to a body part of the user.
A number of suggestions have been made that have a guide member extending from the stem of a golf club or practice club at an angle to avoid contact with the limbs of the user when the club is swung. U.S. Pat. No. 4,682,775 by Wood has the guide member positioned to correct a slice swing. The guide member extends downwardly so that if the club shaft is not rotated in a counter clockwise direction to the desired position, the guide member will contact the rear leg of the user. U.S. Pat. No. 4,145,054 by Stewart is somewhat similar to the concept in U.S. Pat. No. 4,682,775 except that the guide member is intended to pass between the forearms of the user, should the swing be faulty then contact will be made with one or other of the forearms of the user. U.S. Pat. No. 3,918,721 by Tradsk uses a flexible guide member, which is attached to the golf club the end position of the flexible guide member can be placed in a variety of positions. The majority of the uses are related to non-contact positions of the wrist and/or forearm.
There are also a number of documents that make suggestions of apparatuses where the guide member makes contact with part of the body of the user. U.S. Pat. No. 2,462,955 by Glancy has a member which clamps onto the stem of a golf practice stick o
