  • FIG. 5 I20 I50 ,20 I30 DEVICE FOR ADJUSTING BACKSWING ARM POSITIONS OF A GOLF PLAYER BACKGROUND OF THE INVENTION
  • the present invention relates in general to golf accessories, and particularly to a device to assist in finding a proper backswing arm position the thus to correct a golf club swing form of a player during practice swings.
  • the first requirement for a golf player is to grip a golf club in his hands and position or ground the head thereof in the ball hitting area behind a golf ball with the impact face of the club toward the ball. This is known as addressing the ball for preparatory movements and keeping time for a good ball driving action. During this addressing, both arms of the player holding the club stretch out generally aslant downward toward the ground.
  • This invention is essentially intended for correction or improvement of a golf players improper swing form in a backswing motion as typically mentioned hereinbefore.
  • the backswing position adjusting device may also be used versatilely for a left-handed player by putting it on his left wrist and setting the dial thereof and reading the indication thereon in the direction reverse to that in the case of a right-handed player.
  • FIG. 3 is a sectional view of the device taken along y the plane designated by line III-III in FIG. 2;
  • FIG. 4 is a plan view of a second example of the device of this invention.
  • FIG. 5 is a sectional view of the device shown in FIG. 4 taken along the plane designated by line V-V therein;
  • FIG. 6 is a perspective view showing only the cap member for use within the device shown in FIGS. ⁇ 4 and 5;
  • FIG. 7 is a plan view showing a third example of the device of this invention.
  • FIG. 8 is a sectional view of the device shown in FIG. 7 taken along the plane designated by line VIII-VIII therein;
  • FIG. 9 is a perspective view showing an elongated cross member for guiding an impact element for use within the device shown in FIG. 7.
  • cap member 4 of an inverted cup shape made of, for example, a metal.
  • annular guide projection 6 On the inner surface of an upstanding peripheral .wall 5 of the carrier member 3, there is provided an annular guide projection 6, while in the outer surface of a pcripheral wall of the cap member 4, there is formed an annular groove 7 with which the annular projection 6 slidably engages. Accordingly, the cap member 4 is manually rotatable back and forth, as indicated by an arrow B in FIG. 2, inside the carrier member 3 by the guiding function of the annular guide projection 6. Since the cap member 4 is in a certain frictional contact with the carrier member 3, the cap member 4 can be retained in any desired position in the carrier membeer 3 as preset by manual rotation thereof.
  • the carrier member 3 is provided with a pair of lugs 8 for receiving a strap 2, and also in the vicinity of the circumferential portion of the top plate of the cap member 4, there is provided an index mark 9.
  • an index mark 9 In the top surface of the upstanding peripheral wall of the carrier member 3, there is provided a notched scale 10 for reading a predetermined position of the index mark 9. By reading the indication of the index mark 9 on this scale 10, it is possible to know a relative rotating position of the cap member 4 with respect to the carrier member 3.
  • This guide member 12 is, for instance, made of a synthetic resin, having a guiding groove 13 therewithin extending in the diametral direction of the cap member 4.
  • an impact sound maker or striker assembly 15 disposed movable in the diametral direction.
  • This striker assembly 15 comprises a pair of balls 17 supported in opposed perpendicular relation with each other on a striking element 16 to the radial plane of the casing assembly A, the upper ball 17 rollably engaging the guiding groove 13 of the guide member 12.
  • the guiding groove 13 is adapted to guide one of the balls 17 therealong in the lengthwise direction, and when the entire casing assembly A is caused to be inclined in the lengthwise direction of the guide member 12, thus providing an inclined path, the pair of balls 17 together with the striking element 16 moves in and along the guide member 12. At the end of this guided movement the striking element 16 produces a sound of impact when it hits against the inner surface of the peripheral wall of the cap member 4.
  • the backswing position adjusting device When applying this device in club swing or golf ball driving practice, the backswing position adjusting device is secured to the players right wrist as indicated in FIG. 1, and the cap member 4 within the carrier memher 3 is manually rotated to an extent that corresponds to a desired backswing position of the club which has been found beforehand by individual players so that the index mark 9 may be set at-a desired point on the scale 10 for reading by the player. Thereafter a club swing motion is started.
  • the guide member 12 begins to be inclined with respect to the horizontal, and when the arms reach the desired top position so predetermined by setting the index mark 9 on the scale 10 as described hereinbefore, the striker assembly 15, overcoming the frictional force rendered thereupon, moves along the guiding groove 13 toward the lowest position in FIG. 2 (i.e., the rightmost position as viewed in FIG. 3) due to the gravity or weight of the striker assembly 15 so as to hit the inner surface of the peripheral wall of the cap member 4.
  • this cap member 4 and the impact element 16 are made of a hard material such as a metal, respectively, there will be produced a clear impact sound or click at the instant of impact, thus letting the player known when his club upswung overhead reaches as the desired top position so predetermined as mentioned above. Accordingly, if he takes a downswing motion immediately after this impact sound is heard, he will be now assured of a good full swing action, and, therefore, a proper shot in the golf play.
  • FIGS. 4 through 6 there is shown a second example of the backswing position adjusting device of this invention, in which like parts are designated by like reference numerals with a subscript letter a added to those of the first embodiment.
  • a cap member 4a which is rotatably snapped into the inner surface of the peripheral wall 5a of a carrier member 3a is likewise of an inverted cup shape, and a guide member 12a for guiding a sound maker or strik'er 15a in a diametral direction of a casing assembly A, is provided in the center of a top wall 20 of the cap member 4a in such manner that the guide member 12a projects upwardly out of the radial plane of the entire casing assembly A,.
  • the guide member 12a includes a guiding groove 13a in the interior thereof, the guiding groove 13a communicating with the space inside the cap member 4a. Further, the striker 15a is rollably inserted between the guiding groove 13a and the bottom wall of the carrier member 3a so that the striker 15a may contact with the latter.
  • the striker 15a comprises but a single ball, but it may, of course, be of another type of striking means.
  • the device of this example also operates to produce a sound of impact, as the device is worn on the right wrist of a player and displaced to a generally upright position of the right wrist when the club is upswung in a desired top position of a backswing, whereby the striker 15a is caused to hit the peripheral wall of the cap member 4a.
  • FIGS. 7 through 9 wherein like parts are designated by like reference numerals'with a subscript letcarrier member 3b, as shown in FIG. 8, be led to be embedded in apertures 22 provided in the peripheral wall of the cap member 4b.
  • a guide member 12b which is made of a material such as a synthetic resin.
  • the guide member 12b for guiding a sound maker or striker assembly 15b is, as shown in FIG. 9, comprises a gutter-like body including a pair of rails or shoulder 31 on the lateral or longitudinal sides of a bottom wall 30 thereof, a guiding groove 13b being formed between the pair of shoulders 31.
  • On one end, or the upper right end as viewed in FIG. 9, of the gutter-like body there is provided a projection 32 extending upwardly through the top wall of the cap member 4b when assembled therewith, while on the opposite end of the body, there is provided a projection 34 on a bridge piece 33 disposed across the top portion of the both lateral sides of the body.
  • the former projection 32 has a pointed free end as an index point 9b.
  • a pair of guide slots 36 and 37 of arcuate configuration which are disposed opposedly in a diametral direction, one slot 36 being adapted to receive the abovementioned upstanding projection 32 so that it may move along the arcuate slot 36, and the other slot 37 adapted to receive the other projection 34 therethrough, likewise permitting the projection 34 to move therealong. Consequently, the guide member 12b for the striker assembly 15b is thus manually rotatable as a unit in two directions along the slots 36 and 37 through the cooperative engagement between the slots 36, 37 and the projections 32, 34.
  • the pointed free end of the upstanding projection 32 is bent at right angles so as to become parallel to the top wall of the cap member 4b after being assembled into the slot 36 so that it forms the index mark 9b for indication on the scale 10b provided along the inner circumference of the slot 36 on thetop wall of the cap member 4b.
  • a striker assembly b is inserted into the interior'of the guide member 12b so that it may move rollingly in and along a guiding groove 13b therein, the striker assembly 15b comprising a single ball 17b and a strinking element 16b for rollably receiving the ball 17b therein.
  • the under surface of the striker element 166 is set in contact with the upper surfaces of the above-mentioned pair of shoulders 31 so that the strinking element 16b may move slidingly along the shoulders 31.
  • this device can produce a second sound of impact in the finish position of a full swing which is likely to be determined by the extent of a follow-through which is normally proportional to the extent of a backswing.
  • a unique and useful device which is adapted to effectively and properly assist in adjusting a backswing position, thus improving a full swing form through a presetting of the top dial of this device instead of individual and personal impressions of a professional coach or a player which sometimes may be difficult to follow or which may result in the player being mistakenly self satisfied.
