Abstract
A golf swing praticing machine includes a doughnut shaped main frame which has on its entire circumference a circular face that is parallel to a golf club and player's arms and is gradually inclined from outside to the center. The main frame further has a center opening at its center and the upper half of the main frame is bent forward. The main frame is set up in a backwardly inclined state and on the front surface of the circular face are shown three loci indicating the clubhead arcs of backswing, downswing and follow-through and a plurality of straight lines indicating clubshaft arc. When a player swings his golf club along the circular face, the above-mentioned loci move laterally according to the player's weight shift producing substantially an elliptic swing arc.
Description
- The present invention relates to a golf swing practicing machine.
- Practicing of the golf swing is usually done in accordance with the instructions shown in a textbook or given by a coach. Therefore, it is likely that swing would be made only by the arms and wrists, resulting in a rough swing.
- There has been provided a practicing machine which is made up of elliptically assembled rods. With this type of machine, one can practice swinging his club along its elliptical frame. With this practicing machine a player can swing his club along its elliptical path only with his arms and wrists. Accordingly, it is extremely difficult to learn an ideal swing, such as one with a stable head as an axis, steady legs and with the waist turning fully.
- Accordingly, it is a primary object of the present invention to provide a golf swing practicing machine with which one can learn an ideal golf swing easily.
- In keeping with the principles of the present invention, the object of this invention is accomplished by a unique practicing machine in which an inclined elliptical plane is designed in a doughnut shape to enable it to lead the clubhead and clubshaft along the ideal swing arc. The practicing machine is further provided in its inclined doughnut shape plane with plurality of laterally arranged circular locus, which can assist the player in shifting his weight, in stabilizing his head and in efficiently twisting his entire body, thus producing the ideal golf swing.
- The above-mentioned features and object of the present invention will become more apparent with the following description of the invention in conjunction with the accompanying drawings, wherein like reference numerals denote like elements, and in which:
- FIGURE 1 is a perspective view of the.golf swing practicing machine in accordance with the teachings of this invention; showing it in the state of being used;
- FIGURE 2 is a front view of the machine;
- FIGURE 3 is a sectional side view thereof;
- FIGURE 4 is a front view of a base plate;
- FIGURE 5 is a sectional side view thereof;
- FIGURE 6 is a diagram showing the way to draw the swing arc;
- FIGURE 7 is an illustration of the swing arc. which is provided according to the present invention;
- FIGURE 8 is a sectional side view of another embodiment of this invention; and
- FIGURE 9 is a front view showing another embodiment of this invention.
- As can be seen in Figures 1_to 3, a
main frame 5 is provided with acircular face 3 which is gradually inclined backwardly toward the center and is parallel to a clubshaft 1 andarms 2 of aplayer 23. The upper-half of thecircular face 3 is bent forwardly at an adequate angle; themain frame 5 is further provided with acenter opening 4. Themain frame 5 is placed infront groove 7 of abase plate 6 so that themain frame 5 is free to convert its inclination angle by asupport member 8. Thecircular face 3 has a bent-up angle C as shown in Figure 3. - On the entire or partial circumference edge of the
main frame 5 is provided arim 9 which is inserted in thefront groove 7. Therim 9 indicates the swing arc of the clubhead. Provided at the center of thefront groove 7 of thebase plate 6 is amarker 10 which sets the clubhead into the proper position. On thebase plate 6 is further provided ahollow groove 12 in which a mat 11 is placed. Ashoulder pad 13 is provided adjacent thehollow groove 12 of thebase plate 6. Theshoulder pad 13, whose height is adjustable, indicates the proper shoulder position at the top of the swing. Thebase plate 6 is further mounted with a pair offoot pads 14. - On the
circular face 3 andrim 9 are provided loci, shown in Figure 7 which can be drawn according to the diagram of Figure 6. - More specifically, each of the three
vertical lines points inner locus 15c which is drawn around theupper point 15a of the left-sidevertical line 15 indicates the grip arc of the golfclub in backswing; whileouter locus 15d drawn around thelower point 15b indicates the clubhead arc made from address to the top of the backswing. Theinner locus 16c which is drawn around theupper point 16a of the centralvertical line 16 indicates the grip arc of a golfclub in downswing; while theouter locus 16d drawn around thelower point 16b indicates the clubhead arc made from address to the top of the downswing. Theinner locus 17c which is drawn around the upper point 17a of the right- sidevertical line 17 indicates the grip arc of a golfclub in follow-through; while theouter locus 17d drawn around thelower point 17b indicates the clubhead arc made from address to the top of the swing. Then, each of theinner loci outer loci straight lines 18 which are shown by dividing the clubshaft arc into equal intervals. - At the tips of the
straight lines 18 are shown aclubface arc 19 which opens and closes at a fixed angle. - When eliminating certain parts, equal to a
center opening 4, of the loci drawn according to Figure 6, the resulting loci having noinner locus circular face 3 andrim 9, as are shown in Figures 1 and 2. - As shown in Figure 6, all the points of intersection of the
straight lines 18 showing the clubshaft 1 and theouter loci inner loci inner loci center 21. A slightly inclin-edstraight line 18a denotes the clubshaft at address, and the position of the ball is indicated as being at 22. - As is shown in Figure 3, it is preferable to set the angle a at 50° to 70°, the angle b approximately at 119° and the angle c at about 110.5°. The angles a and b can be converted when the
main frame 5 is raised and lowered. The angle c can be adjusted by moving the upper-half of themain frame 5 up and downwardly; the position of the angle c may convert to some upper position as the length of the golfclub is shortened. The angular width of angle c is concerned with the clubface speed to open at 90°. If the clubface opens at 90° in a fast backswing, the angle c becomes wider; while, if the moment when the clubface opens at 90° delays, the angle c becomes smaller. Therefore, at the time when the clubface opens at 90° at the top of the swing, the angle c is minimized. On the other hand, the moment in which the clubface ope_ns at 130° in the follow through is almost the same everytime, having nothing to do with the downswing. The clubhead opens at 90° in the backswing and at the top of the swing, and closes at 180° in the downswing and the follow through. - As shown in Figure 1, the elliptical locus around the center 20 will not generate centrifugal force, but the circular locus showing backswing, downswing and follow through will generate centrifugal force. A square club swing is different from the mechanical circular motion. Therefore, according to the square club swing it is impossible to start the swing from the center of one circle and to start the swing with cocking the wrists.
- There are in a golf swing two centers showing the center of the inside circle of the clubshaft arc and the center of the outside circle of the clubhead arc. A player swings his club freely within the two circles with his wrist cocking and uncocking. In the
loci lower centers vertical lines line 15 position together with the shift of the player's body weight and the centers move from 15a and 15b to 16a and 16b and to 17a and 17b; as a result, the whole club swing draws an elliptical arc. At this moment, the vertical intervals betweencenters vertical line 16 differs sometimes from each other. The rotary angle of the club face opens and closes in an equal angle. - In use of the practicing machine described above, as is shown in Figures 1 and 2, the
player 23 who practices golf swing sets up at thefoot pad 14; namely, behind thecenter opening 4 of themain frame 5 and sets his golf club at thecircular face 3 to make a practice swing along the loci shown on thecircular face 3 andrim 9. - More specifically, when a player swings his club following the
outer loci straight line 18 indicating the locus of the clubshaft 1 and themark 19 indicating the arc of the clubface angle and along thecircular face 3, each circular locus smoothly moving laterally according to the player's weight shift during the backswing, downswing and follow-through producing sufficient centrifugal force. The swing made according to the above-described way keeps the player's head steady; therefore, the player can learn an ideal golf swing in which his head functions as a swing axis and his whole body is turned sufficiently. It is incidentally, effective to set up mirrors in front of and on both sides of themain frame 5 when theplayer 23 practices golf swing with the above-described machine. - Shown in Figure 8 is another embodiment of the
main frame 5 of the present invention. In this embodiment, atransparent flap 23, which is the same shape and size as thecircular face 3, is secured spacedly in front of thecircular face 3, forming a guide groove.24 therebetween. In practicing, the clubshaft may be guided by theguide groove 24. This embodiment can eliminate to show the straight lines which indicates the arc of the clubshaft 1. However, it is possible to show the above-mentioned loci and straight lines on thetransparent flap 23. - Furthermore, as is shown in Figure 9, the three loci indicating the clubhead arcs in the backswing, downswing and follow-through and the straight lines indicating the-arc of the clubshaft 1 can be formed by a plurality of
rods 25 which- are connected to one another. - The present invention as described above, has the following advantages to the prior art.
- The practicing machine of this invention is constructed in such a manner that the main frame provided with a circular face which is parallel to the clubshaft 1 and player's
arms 2 and is gradually inclined backwardly from outside to its center and further provided with acenter opening 4 in its center is placed on thebase plate 6 in a backwardly inclined figure by its inclining angle adjustable by the supportingmember 8. Therefore, aplayer 23, setting up behind thecenter opening 4, can swing his club along the circulr face 3 which is parallel to the clubshaft 1 and player'sarms 2. Furthermore, theplayer 23 can easily recognize the swing arcs which are shown on thecircular face 3 because themain frame 5 is inclined backwardly. - On the
circular face 3 andrim 9 are shownouter loci lower points vertical lines circular face 3 andrim 9 are also shown thestraight lines 18 which indicate the arcs of the clubshaft 1 connecting theinner loci upper points outer loci circular face 3 andrim 9 aremarks 19 which indicate the locus.of the club face angle. Therefore, during club swing above, each . locus moves laterally according to the weight shift of the player who makes backswing, downswing and follow-through producing efficient centrifugal force. - It should be apparent to those skilled in the art that the above-described embodiments are merely illustrative of but a few of the many possible specific embodiments which represent the applications of the principles of the present invention. Numerous and varied other arrangements can be readily devised by those skilled in the art without departing from the spirit and scope of the invention.
