Definitions
- the invention relates to the sports field and more specifically the field of golf.
- Golf is a sport whose high technicality often constitutes a difficult obstacle to be overcome by the players. For this reason, golf players generally have to use education to develop their game.
- the swing is the technical basis of golf and can be broken down into four phases: a placement and aiming phase (the address), a preparation phase (the ascent), a driving phase (the descent), a frenetic phase (the final).
- the swing technique is therefore preferred in the context of golf teaching, each of the phases that can be worked on.
- the main objective of the present invention is therefore to provide an educational tool for teaching golf allowing the player to better understand the movement of his club at the impact zone with the ball.
- Another objective of the invention is to propose such a tool which can be adapted to any type of club. Depending on the circumstances of the game, golfers use clubs differentiated by the angle of inclination of the face or loft, calculated from the axis of the handle, this angle ranging from zero degrees for the putter, up to '' at around 70 ° for the most open club.
- Yet another objective of the invention is to propose such a tool which can be used to allow the player to refine the trajectory given to the club but also the striking height of this club compared to a ball.
- a device for teaching golf characterized in that it comprises an essentially flat base, a head mounted on said base having a face essentially inverted with respect to the face of the head of a golf club, and means for indicating the striking angle of said club on said head comprising a disc integral with said head and mounted for rotation on said base essentially in the plane thereof, said head being positioned substantially in the center of said disc, and means for visualizing the displacement of said disc relative to said base following the impact of said club on said retractable head
- trajectory followed by the ball following the impact of the club on it depends essentially on three parameters, namely: - the path followed by the club which determines the initial path of the ball;
- the player can thus correct his swing and possibly his address so as to improve the quality of the impact and consequently the trajectory followed by the ball. the base of the device so as not to protrude therefrom.
- the base of the device according to the invention has a thickness provided to allow it not to exceed too much of the ground so as not to disturb the player and allow him to take a position identical to that which he would take on a golf course.
- this base can be covered with a material imitating the lawn.
- this base preferably does not have any projecting element, apart from the retractable head, so that the swing can take place normally.
- the head of the device is mounted mobile on said base and capable of being retracted under the impact transmitted by a golf club so as not to hinder its trajectory.
- this head can also be made of a material having a certain elasticity and fixed by its base to the base. According to such a characteristic, the head can retract temporarily upon impact of the club and automatically return to position after the passage of the club.
- the means for indicating the striking angle of the device are implemented so as to reflect the quality of this angle.
- the device therefore constitutes a device allowing the player to work on the quality of the impact which he instills in the ball thanks to the club.
- the invention thus makes it possible to tackle a pedagogical aspect of teaching golf which is particularly interesting since it is close to the real conditions for practicing this game.
- the rotation of the disc can be facilitated by the presence of bearings.
- means may also be provided for attenuating this rotation.
- Such a goal can in particular be obtained by not using ball bearings while limiting the surface of the base in contact with the lower part of the disc.
- Such a goal can also be obtained by providing surface irregularities or a slope on a part of the base in contact with the disc. It may also be envisaged to limit the rotation of the disc by creating friction between the folded head and the base.
- these means of viewing the movement of the disc can be constituted in many ways.
- these display means comprise a graduation provided on said disc and / or on said base.
- a graduation makes it possible to give more precise indications on the typing angle and thus on the extent of the typing error.
- this graduation is colored. This graduation can thus, for example, consist of a arrow or any other indicator sign provided on the disc (or on the base) and quarters of different colors distributed around the disc on the base (or around the base on the disc).
- the retractable head is constituted by an element integral with the disc comprising two attachment arms thereon, said arms extending essentially over the entire diameter of said disc.
- the forces transmitted by the face of the club to the inverted face of the retractable head are communicated to the periphery of the disc since they are not perpendicular to this inverted face and sufficiently amplified to result in significant movement. of the disc. It is indeed important that the disc rotates enough to signal the fault to the user of the device and the extent of it.
- the means allowing the rotation of the disc on the base must be chosen so as not to slow down the movement of the disc but also, as specified above, not to amplify it too much so as to allow a qualitative assessment but also quantitative of the typo
- said head is removable and interchangeable.
- said device comprises means for adjusting the inclination of said head, which also allows the latter to adapt to all golf clubs, by allowing its inclination of its inverted face to be greater or lesser.
- these adjustment means will be designed so as to allow the inverted face of the head to be positioned vertically (corresponding to a putter type club), up to an angle of approximately 70 ° (corresponding to the most open). They can for example be constituted by a toothed stud placed in front of the head in a recess specially provided for this purpose and which can cooperate with notches provided on another part so as to be able to adopt several positions.
- the quality of the impact transmitted by the club to the ball depends on the striking angle but also on the striking height of the ball.
- the device according to the invention may also include means for indicating the height of strikes said club on said retractable head.
- the terms "means for indicating the striking height” are understood to mean means making it possible to give a more or less precise indication of the height of the impact carried by the club on the head.
- these means for indicating the striking height will consist of the material covering the base. In this case, this material will present surface irregularities which will cause a noise when they are touched by the club during the swing. Such a material could for example consist of synthetic turf.
- these means may consist of an element mounted to move in the retractable head and capable of being retracted only when the striking height of said club on said retractable head is correct.
- an element mounted to move in the retractable head and capable of being retracted only when the striking height of said club on said retractable head is correct.
- Such an element is described in patent application FR 9507615. During the swing, this element will only be knocked down when the impact of the club on the head occurs at a sufficiently low height of the base. The height of this second element will therefore be chosen so as to correspond to a correct striking height according to the practice of golf.
- the player can thus work not only the striking angle instilled by the club but also the striking height, which is particularly important for beginners, who very often tend to hang the ground during the swing. .
- FIG. 1 shows a general perspective view of said embodiment
- FIG. 2 shows a top view of the central part of the device according to Figure 1;
- FIG. 3 shows a half-sectional view of the device shown in Figure 1;
- FIG. 4 shows a bottom view of the rotating disc of the device
- - Figure 5 shows a front view of the retractable head
- - Figure 6 shows a sectional view of the tilt adjustment means of the retractable head.
- the device for teaching golf essentially comprises a base 1, a retractable head 2 and means for indicating the striking angle 4 including a disc 8 rotatably mounted on said base 1 and on the axis of rotation of which is fixed the retractable head 2
- the retractable head has a face 3 essentially inverted with respect to the face of the head of a club so as to essentially marry the club face in the event of a correct impact of a club against said retractable head.
- this head Under the effect of the impact transmitted by such a club during a swing, this head is capable of being folded down so as to be housed in an opening 11 in the disc 8 specially provided for this purpose and designed in such a way that when the head 8 is folded back into the opening 11, this head does not protrude from the disc 8 so as not to hinder the continuation of the swing after the impact.
- the head 8 Under the effect of the impact, the head 8 is also capable of communicating a movement of the disc 8 relative to the base 1, if the striking angle between the face 3 of the retractable head and the face of the club head is not substantially equal to 0, that is to say if the striking angle and therefore the swing are not correct to correspond in real life to an acceptable trajectory of the ball.
- visualization means In order to materialize the extent of the fault committed, visualization means
- these display means 12 are constituted by an arrow 12a cooperating with a colored graduation 12b provided on the base 1 at the periphery of the disc 8. It will be understood, however, that these display means may be constituted by any other suitable means. Thus, it could in particular be envisaged to provide a window in the disc 8 so as to allow the visualization of a colored graduation on the part of the base 1 present under the disc 8.
- the disc 8 therefore rotates in one or the other possible direction of rotation symbolized by the double arrow 13.
- the arrow 12 indicates the one of the colored graduations 12b. It is thus possible for the player to assess the importance of the fault committed and thus to work on his swing to manage to fold down the retractable head 2 without the disc 8 rotating, thus reflecting that the club face correctly attacks the retractable head, to correspond in reality to a good trajectory of the ball.
- the retractable head consists of an element 6 mounted integrally on the disc 8.
- the disk 8 With reference to FIG. 3, in order to allow the movement of the disk 8, it is fixed on a bearing 14 mounted in rotation on the base 1 by means of a ball bearing 15, as can be seen in FIG. 3.
- the assembly rests on a base 16.
- the first element 6 has arms 9a, 9b extending along the diameter of the disc 8 and making it possible to transmit the forces instilled by the club during impact on the periphery of the disc, allowing rotation thereof as soon as these forces are not perpendicular to the inverted face 3 of the retractable head 2. Furthermore, the upper part of the element 6 is notched so as to facilitate the raising of this element when the head is retracted. Note that it could of course be considered other means of raising this part without departing from the scope of the invention.
- the player When using the device described, the player after choosing his club positions the retractable head 2 at the angle corresponding to the club in question. Once, the retractable head 2 inclined at the angle corresponding to the club used, the player can take his position relative to the retractable head in the same way as he would position himself in real face of a golf ball, and work the impact he communicates to the head through his club.
- the quality of the striking angle is given by the rotation of the disk 8. If such a rotation does not occur, the striking angle is considered to be correct. If disk 8 observe a rotation following impact, the strike angle is incorrect. According to the quarter of color 12b indicated by the arrow 12a, the extent of the fault can be easily and quickly assessed by the player.
