THOMAS E WILLIAMS BY ATTOR N EYS United States Patent O 3,101,949 GOLF SWING AN ALYZER Thomas F. Williams, Dayton, Ohio, assignor to William Mullins, Dayton, Ghio f Filed Sept. 3, 1959, Ser. No. 838,637 2 Claims. (Cl. 273-186) This invention pertains to golf swing analyzers.
A principal object of this invention is to provide a golf swing analyzer which causes an indication of the path of the swing of a golf club to be made on the head of the club.
A further object of this invention is to provide a golf swing analyzer which is suitable for identifying a great number of swing faults, and to serve as `a golf practice unit.
Another object is :to provide -a golf swing analyzer of rugged construction for long service life without repair.
A further object of this invention is to provide a golf swing analyzer Which is cushioned to absorb the shock of being hit by the head of a lclub.
Other objects and advantages of the invention will be apparent from the following description, .the accompanying Adrawings and Vthe appended claims.
In the drawings:
FIG. 1 is a pian view of the analyzer of this invention;
FIG. 2 is a section through the analyzer taken generally along line .2 -2 of FIG. l;
FIG. 3 is a section through one Iof the markers 'along line 3-3 of FIG. l;
l FIG. 4 is a fragmentary plan View of the tee and one marker from each of the inside and outside rows showing the application `o lcolored' material tothe outside surface thereof; and
FIGS. 5-8 Iare examples of marks caused to be made on the head of Ia golf elub illustrating 'the results fof typical swings.
Referring to the drawing, which illustrates a preferred embodiment of this invention, the golf swing analyzer is shown yas having a `generally at longitudinally extending base 1t). The base lil may be ionned of sheet metal 11 with preferably a rubber coating 12 on the 'top surface, and a section of rubber padding 13y is mounted on the bottom surface adjacent each end of the base lll.
Means supported on Ithe base for causing a recognizable mark to be made lon the head of a golf club includes an inside now 141of markers 15 arranged in spaced relation adjacent one longitudinal edge of the base 1li and an outside row 16 4of the markers 15 similarly arranged ialong its opposite longitudinal edge of the base 10. The inside and outside rows -deiineV therebetween a swing path 18 longitudinal of the base lll.
The markers consist fof short vertical upstanding sections 20 of hollow :rubber tubing formed with an enlarged ground engaging disk-like foot 21 on the bottom thereof. Preferably, the markers 15 consist of golf driving practice tees, and have an outer surface 2.2 which may be coated with suitable colored material to make a recognizable mark `on the head of a club when swung into contact with the vertical section 20. The sections 20 of the markers 15 are brought through openings formed in the sheet metal 11 and the coating 12 of the base 10 within which rubber grommets 25 have beenpositioned. The grommets 25 form `a .cushion which protect the markers 15 from being cut by the .edge of the sheet metal 11 of the base when hit by la club.
A ball .tee 30, which is also employed as a marker, is placed preferably in the :center of the swing path 18. The ball tee has la section 20' preferably of a shorter vertical extent than the sections 20 4of the markers 15.
In addition to the tee 30, a marker 31, which may be identical with ythe markers 15, is adjustably positioned further down the swing path 1S to provide 1a follow through marker to cause an indication to be made on the head of a club when it has -been properly swung'through the path 18. An unused opening 32 in the path 18 provides for the adjustment of the position of the follow through marker 31 as desired by the golfer.
It will be seen that the markers 15, when inserted through the grommets 25 from beneath the base 10, form a cushion which holds the base 10 in spaced apart relation with reherence `to a supporting floor tor the ground. The .cushion padding 13 formed on the underside of the Ibase 10 adjacent the ends thereof may not necessarily touch the floor when the analyzer is on .a smooth surface, but serve to protect the supporting surface from being marred by accidental or sudden contact yof `the base 10. lIt is also seen that the feet 21 4of the markers 15 prevent slipping of the analyzer when placed on a smooth surface.
Means for causing a recognizable mark to be made on the head of a golf club when swung into contact with the marker 15 includes marker Ichalk 35. The chalk 35 .may consist of china marking pencils or any other material suitable for coating the surface 22 of the sections 20. The chalk 35 is conveniently attached to the base 1@ by 'an elastic strap 36. Also, la carrying handle 37 may be tiXed to one edge of :the base 10'.
In the operation of this invention, the portion of .the `outer surfaces 22 of the inside row of markers 14 is coated with one color of the chalk 35 for making a recognizable mark von the head of a club when swung into contact therewith, and the outside row 16 is coated with a different color for making a different recognizable mark. Similarly, the tee 3i) and the follow through markerl in the swing path 18 are coated with different colors of the chalk 35 for causing still different recognizable marks. The manner in which the surface Z2 is coated may be understood by reference to FIGS. 2 `and 4 where the coated portion of the surface 22 of the individual marke-rs is indicated at 38. It is, of course, understood that markers 15 may be employed which themselves have an ability to cause a desired recognizable mark to be made on the club without the necessity of applying :a coating 38. However, the golf tees preferably employed, as shown, are made of `durable rubber to withstand punishment mather than to apply by ablation any color of their own to the. golf club. Y
The golfer stands at `one side of the analyzer, and the side to which he stands depends upon whether he swings right or left handed. An `outline of the head et) of a club is fonned on FIG. l to illustrate `the position of a club in address for a right handed golfer. A ball, such las a practice -ball for inside hitting or an ordinary golf ball if used outdoors, may be placed on the tee 3l?. lf desired, no Iball at all need be used since the golfer may swing down on the tee 30 in place [of hitting a ball olf the tee, with equivalent results.
It is assumed that the surfaces 22 of the inside row 14 of markers are coated with one distinctive color, such as blue for the purpose of illustration: Similarly the outside row may be coated with red, the tee 30 coated with orange, and the follow through marker 31 with green. 'Ihe 'coating 38 is applied generally as indicated in FIG. 4 so that the surface 22 of the marker exposed to the movement of the head 4l) is coated. The golfer then proceeds to make an ordinary swing. The colored marks made on the face and sole plates of the head 4l) provide `an accurate indication of the path of the swing.
The club heads 4) of FIGS. 5-8 have been marked for the purpose of illustrating examples of a few of the many indications which may be provided by this invention. The shadings on the heads 40 correspond to the colors indicated above, and the shading designated by reference numeral 44 represents orange, 45 represents green, 46 represents lred, and 47 represents blue, although it is understood that `any combination may be used. FIG. represents a perfect swing since the head 40 has contacted the tee 30 squarely in the middle as indicated by the orange 44 on the head of the club, and has proceeded through to pick up some green 45 of lthe follow through marker 31.
A typical swing which would result in #a slice is shown in FIG. 6 where the orange `of the tee 30 is shown as having been picked up adjacent the heel of the head 40, thereby imparting a :clockwise rotation to any ball which might have been placed upon Vthe tee 30. The displacement of the orange as compared to the green of the follow through marker 31 indicates a diagonal travel of the head 40 through `the swing path 13. FIG. 7 shows an insideout swing where `some blue is shown as having been picked up near the heel of the head 40 from the inside row 14, orange from the tee 30, and red from the outside row 16. The analyzer of this invention indicates the manner in which the head of la club has contacted a marker 15, whether at the head or the heel `of nthe club as indicated -by the above examples, and whether high or lo-w as indicate-d by the example `of FIG. 8 where the swing 'was too high. High contact which would result in the topping of a ball `and 4results in marks being made by the markers on the sole plate only, or perhaps no mark at all.
Other examples `of individual errors Iwhich may be detected by this analyzer include head up or pulling back, over reaching, arch too fiat or too sharp, open or closed face, arm and wrist roll, etc. It will therefore be seen that the yanalyzer of this invention combines versatility and simplicity with rug-gedness, and is suitable for indicating and assisting in the correction of a great number of common golfing faults.
While the form `of apparatus herein described constitutes a preferred embodiment `of the invention, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
