DESCRIPTION:
BRIEF SUMMARY
The invention relates to the field of sport and more precisely to the field of golf.
Golf is a sport whose highly technical nature often constitutes a difficult obstacle for its players to overcome. For this reason, golf players must generally turn to a course of learning in order to develop their game.
The swing is the technical basis of golf and may be broken down into four phases: a placement and aiming phase (the address), a preparation phase (the back-lift), a motive phase (the descent), a slowing down phase (the finish). The technique of the swing is therefore given great importance in the context of the teaching of golf, it being possible to work on each of the phases that make it up.
So as to permit golfers to improve their swing, within the state of the technology, there are pieces of equipment designed to allow them to work on the movements that form the basis of the swing.
Within the state of the technology, there are also items of equipment that allow the movements of the club to be displayed. Such equipment uses various techniques (photography, video, analysers, lasers, computers . . . ).
Nevertheless, it becomes apparent from the teaching of golf that many players despite great effort of will, do not achieve the essential physical requirement of feeling the area of impact of the club on the ball. From this follows poor control of the trajectory of the club, the angle formed by the club against the ball and, consequently the trajectory followed by the ball subsequent to the impact communicated by the club.
The main objective of this invention is to provide a pedagogic tool for the teaching of golf that allows the golfer to better understand the movement of his club at the level of the area of impact with the ball.
Another objective of the invention is to provide such a tool which can be matched to any type of club. According to the circumstances of the game, golfers use clubs which are differentiated from one another by the angle of inclination of the face or the loft, calculated from the axis of the shaft, this angle going from zero degrees for the putter up to about 700 for the most open club.
Yet another objective of the invention is to provide such a tool that is able to be used to allow a player to perfect the trajectory given to the club and also the height of the strike of this club in relation to a ball.
Yet another objective of the invention is to provide such a device of mechanical design that does not require the operation of any electric or electronic component.
These different objectives are achieved thanks to the invention which relates to a device for the teaching of golf characterised in that it includes an essentially flat pedestal, a head mounted on said pedestal having a face that is essentially reversed with respect to the face of the head of a golf club, and means for indicating the strike angle of said club on said head that includes a disc integral with said head and rotatably mounted on said pedestal essentially in the plane of the pedestal, said head being positioned approximately at the centre of said disc, and means for the display of the displacement of said disc in relation to said pedestal following the impact of said club on said retractable head.
It should be noted that the trajectory followed by the ball following the impact of the club on it depends essentially on three parameters, namely: ball; final observed effect on the ball, with respect to the ball (the strike height).
According to the information supplied by the disc of the device, the player can then correct his swing and possible his address in a way that improves the quality of impact and, as a consequence, the trajectory followed by the ball. Such a disc is integrated into the pedestal of the device in such a way that it does jut out from it.
The pedestal of the device according to the invention has a thickness provided for it that does not allow it to protrude over too much ground so that it does not hinder the player and allows him to take up a position identical to the position he would take on a
