A? 7' OE/V5545 United States Patent 3,138,388 DEVICE FOR COORDINATING THE PIVOTAL MOVEMENT OF A GOLFERS SHOULDERS AND HIPS Charles C. Herold, 10220' SW. 160 St., Miami, Fla. Filed Oct. 6, 1961, Ser. No. 143,334 6 Claims. (Cl. 273-183) This invention relates to the general field of athletics and, more specifically, the instant invention pertains to apparatus for the training of a golf player.
As every player of golf is well aware, stance and the movement of the body and its appendages must be coordinated in order to properly strike the object ball with a selected club, else the impact of the club head on the ball will cause the latter to slice, hook, be topped, or undercut. The players arms, shoulders, torso, hips and legs must move in coordination to achieve a satisfactory stroke. To this end the present invention is directed.
One of the most diificult phases of the golf game resides in a players mastery of the use of clubs generally classified as woods and irons. In using such clubs, the player normally addresses the ball, after which the club is swung upwardly over the shoulders and subsequently downwardly to cause impact of the golf club head with the golf or object ball. Most of the human errors, leading to a poorly hit ball, occur during the downswing. Many players, even after having developed a smooth, rythmical swing, have a tendency to draw the club inwardly as the club head approaches the ball. Other players tend to chop at the ball. Other irregularities occur in the downswing of even the most experienced of players. Regardless of the age, weight and strength of the player these, as well as other improper body movements, result in inaccurate shots with, of course, the attendant increase in score.
In accordance with the present-day techniques for playing an iron or wood shot, it is understood that the shoulders, torso, hips and legs pivot during the upswing. During the downswing most players tend to turn their shoulders well in advance of pivoting their hips and legs in the reverse direction and, consequently, the ball, thus, is struck inwardly with respect to the player if, indeed, the ball is struck at all.
The instant invention is designed to aiford the user apparatus which will tend to overcome the swinging defects on the downstroke of a golf shot. As such, the instant invention has, as one of the primary objects thereof, the provision of apparatus to train or guide a golf player to perfect the downswing portion of a golf stroke.
Another object of this invention is to provide apparatus of the type described which is bodily actuated.
A further object of this invention is to provide a bodilyactuated golf swing practice or training device for correcting a golf players downswing, the device being adapted for use indoors or outdoors.
Still another object of this invention is to provide apparatus for guiding the backswing of a golf player, the apparatus including body-engaging elements movable with the player if the swing is correct, the elements being nonmovable in the presence of an improper swing.
This invention contemplates, as a still further object thereof, the provision of a golf swing practice device which includes normally movable body-engaging elements when the swing is correct, the elements becoming nonmovable to inhibit body movement when the golf swing is incorrect.
Other and further objects and advantages of the instant invention will become'more manifest from a consideration of the following specification when read in conjunction with the annexed drawings, in which:

Referring now more specifically to the drawings, reference numeral 10 designates, in general, a golf swing guide apparatus constructed in accordance with the teachings of the instant invention.
' The golf swing guide apparatus is seen to comprise an elongated substantially rectangular platform 12 having a longitudinally-extending triangular base 14 projecting from one end thereof.
Reference numeral 16 designates a hollow tubular element having a circumferential flange 18 bolted as at 20 to the base 14 adjacent the apex thereof. The tubular element 16 extends vertically and has telescoped in the upper end thereof a second hollow tubular element 22. The tubular elements 16, 22 are held in vertically-adjusted relation relative to each other by means of a wing bolt 24 which is threaded through the tubular element 16 for engagement with the tubular element 22. The upper end of the tubular element 22 is collapsed at 25 to form a flat face having radially-extending ratchet teeth 26. Reference numeral 28 denotes a relatively short hollow tubular elbow connector having a lower flattened end 30 formed with radially-extending ratchet teeth 32 adapted to mate with the ratchet teeth 26 when superimposed thereagainst. With the ratchet teeth 26 juxtaposed with respect to the teeth 32, the elbow 28 is held in adjusted relation relative to the tubular element 22 by means of a bolt 34 which passes through the centers of the radial ratchet teeth 26, 32, and a wing nut 36.
To serve a function to be described, the lower end of the elbow 28 has a circumferential collar 38 telescoped thereon and being rotatable relative thereto. A set screw 40 is threaded through the collar 38 to hold the collar against inadvertent rotary or axial movement. The collar 38 is also provided with a plurality of transverselyextending, circumferentially-spaced cylindrical pin-receiving openings 41 in one of which is selectively disposed a limit pin 42.
A second collar 44 is telescoped over the lower end of the elbow 28 and is superimposed on the collar 38. The collar 44 is rotatable about the elbow 28 and rides on the collar 38 as it turns. A stop pin 46 is threaded into the collar 44 and projects radially therefrom. As is clearly seen in FIGURE 6, the limit pin 42 is disposed in the path of movement of the stop pin 46 and thereby limits the rotation of the collar 44.
The inner side of the collar 44 is formed with an arcuately-shaped cam slot 48 that normally faces an aperture 50 formed in the lower end of the elbow 28 (see FIGURES 4, 6 and 7). One end of a lever 52 normally extends through the aperture 50, and is releasably received within the cam slot 48. The other end of the lever 52 is bifurcated at 54 and receives therein the lower end of a bell-crank lever 56 that is pivotally connected thereto by a pivot pin 58. The bell-crank lever 56 is pivotally mounted, intermediate its ends, on a pivot pin 60, the latter extending diametrically across the elbow 28 substantially centrally thereof and having its opposed ends fixedly secured thereto. The other end of the bellcrank lever 56 extends into the upper end of the elbow 28 and is pivotally connected by a pin 62 to the bifurcated end 64 of a pawl 66. The other end of the pawl 66 is mounted for reciprocation through an aperture 68 formed in the upper end of the elbow 28.
A collar 70 having a plurality of circumferentiallyspaced, transversely-extending cylindrical openings 72 formed therein to receive, selectively, a limit pin 74, is telescoped over the upper end of the elbow 28 and is rotatable thereon. The collar 70 is held against rotation in an adjusted position on the elbow 28 by means of a set screw 76.
The enlarged end 78 of an elongated substantially hollow tubular member 80 is telescoped over the upper end of the elbow 28 and bears against the collar 70. One end of a stop pin 81 is threaded in the end 78 and is adapted to engage the limit pin 74. The hollow tubular member 80 is rotatable on the elbow 28, and the inner side thereof is formed with a ratchet slot 82 which normally confronts the aperture 68 and receives the free end of the pawl 66 therein.
A spring seat 84 is formed in the inner side of the upper end of the elbow 28 and holds one end of a helicoidal spring 86 under compression, the other end of the spring 86 surrounding a spring keeper pin 87 which projects laterally from the upper end of the lever 56. The keeper pin 87 constantly tends to guide the aforementioned other end of the spring into engagement with the upper end of the bell-crank lever 56. Thus, the lever 56 is constantly biased for pivotal movement in a clockwise direction, reference being made to FIGURE 4 of the drawings.
One end of a rod 88 is telescoped into the tubular member 80 and is fixedly secured thereto. The other end of the rod 88 is threaded to receive a number of convolutions of a helicoidal spring 90 thereon. The convolutions of the spring 90 at the other end thereof are threaded on the threaded end of a similar rod 92 which is telescoped within one end of a tubular member 94. The adjacent ends of the rods 88, 92 are spaced from one another, and the construction is such as to provide a semi-rigid connection between the tubular members 80 and 94. The tubular member 94 is held in adjusted relation relative to the rod 92 by means of a wing bolt 96, and a shoulderengaging, substantially rectangular bar 97 is rigidly connected, intermediate its ends, to the upper end of the tubular member 94.
A rod 98 has one of its ends threaded into the collar 44 diametrically of the pin 46, the other end of the rod 98 being threaded to receive some of the convolutions of a helicoidal spring 100 thereon. The other end of the spring 100 is threaded on one end of a rod 102. The construction between the adjacent ends of the rods is such as to afford a semi-rigid connection therebetween, the adjacent ends thereof being axially spaced from one another.
The other end of the rod 102 is connected by a screw 104 to a buttocks-engaging crossbar 106 intermediate the ends of the latter.
Having described this invention in detail, the following is a brief description of the operation of the apparatus 10.
Referring to the several figures of the drawings, the wing bolt 24 is first loosened to permit the tubular element 22 to be vertically adjusted relative to the tubular element 16 so as to position the crossbar 106 across the buttocks of the user (see FIGURE 9), and the bolt 24 is then thereafter tightened.
The angularity of the tubular members 80, 94 is adjusted through the simple expedient of loosening the wing nut 36 and adjusting the tubular members 80, 94 about the bolt 34 and then subsequently tightening the nut 36. The wing bolt 96 is loosened to permit axial and pivotal adjustment of the tubular member 94 relative to the rod 92 to fit the shoulder-engaging bar 97 against the users shoulders.
With these adjustments having been made, reference is now made to FIGURES 5, 6 and 10. The latter figure shows the position of the user at the top of his normal backswing with the hips and shoulders pivoted to the right. The free end of the lever 52 is now disposed in the cam slot 40 (see FIGURE 6) and the pawl 66 is engaged in the ratchet slot 82 (see FIGURE 5).
Now, as has been stated above, to make a proper wood or iron shot, the hips of the golfer should begin to pivot in a reverse direction prior to the initial movement of the shoulders. Thus, and reference is made to FIGURE 11, the hips have been moved in advance of the shoulders, and this motion is transmitted to the collar 44 which will then turn in a counterclockwise direction, causing the cam slot 48 to move past the lever 52 (see FIGURE 7), and to simultaneously press the same inwardly. This causes the lever 56 to pivot counterclockwise, reference being made to the dotted-line position thereof shown in FIGURE 4, with the attendant withdrawal of the pawl 66 from the ratchet slot 82 (see FIG- URE 8). This frees the tubular member for rotation about the upper end of the elbow 28 so that the natural downswing of the golfer may be completed.
In the event the hips do not pivot in advance of the shoulders, the tubular member 80 remains locked, since the pawl 66 remains within the ratchet slot 82, and pressure will be applied to the shoulders of the user, warning him of an impending incorrect swing. The helicoidal spring tends to absorb the force generated under the latter condition to prevent injury to the apparatus and physical injury to the user, should the tubular elements 80 and 94 be made without the semi-rigid connection.
The semi-rigid helicoidal spring also provides a connection which permits slight body movements to be absorbed therein without transmission to the collar 44 through inadvertence.
The stop pins 46, 81 cooperate with their respective limit pins 42, 74 to prevent excessive pivotal movement of the hips and shoulders as the golfer assumes the position shown in FIGURE 10.
In event the spacings of the openings 41, 72 do not provide fine enough adjustment for the pins 42, 74, the set screws 40, 76 may be loosened and the collars 38, 44, 70 rotated about the sleeve 28 until the desired position of the pins 42, 74 is obtained. The set screws are then re-tightened.
Having described and illustrated one embodiment of this invention, it will be understood that the same is offered merely by way of example, and that this invention is to be limited only by the scope of the appended claims.
