GOLF SWING CORRECTIVE MAT Novice and many intermediate golfers have difficulty in correctly swinging their drivers when performing a tee shot. Most frequently a golfer having an incorrect swing will swing the club in a manner such that the head portion thereof swings across and to the inside of the intended line of flight of the ball as the club head reaches its lowermost position immediately adjacent the ground. With this type of incorrect swing the club head does not meet the ball squarely and as a result of this incorrect impact of the club head with the ball the latter has a tendency to veer horizontally outwardly of the are through which the club head is swung and the ball is caused to rotate about a generally vertical axis in a direction inherently causing the ball to veer still further in the same horizontal direction during flight of the ball. This particular type of tee shot which causes the ball to veer excessively toward the outside of the golfers swing is referred to as a slice."
In order to teach novice and intermediate golfers who have a tendency to slice" a correct swing which will not result in a slice instructors advise their students to swing out and through. Of course, this term does not have reference to the club head since outward cutting across of a club head relative to the line of intended flight of the ball would result in opposite veering of the golf ball which is termed a hook, but has reference to the hands of the golfer swinging the club inasmuch as the normal tendency of the hands of a golfer swinging during a tee shot is to swing around with the golfer as he pivots. Accordingly, in order to correct a slice" golfers are instructed to swing their hands in a manner such that their hands swing out and through which, if such instructions are carried out, results in the club head swinging directly along the intended line of flight of the ball during that portion of the swinging of the club head in which the head impacts with the teed ball.
While verbal instruction of a pupil to swing out and through" with his hands is at least partially effective in most instances, the result of such instruction does not approach 100 percent effectiveness and accordingly, it is the main object of this invention to provide means by which the swing of a golfers hands may be guided during each swing.
Another object of this invention, in accordance with the immediately preceding object, is to provide visual means which may be readily viewed by the golfer continuously during the period of swinging a club for a tee shot.
A still further object of this invention, in accordance with the immediately preceding objects, is to provide a visually ascertainable path near ground level, spaced slightly outwardly of the path through which the club head will swing and inclined forwardly and outwardly relative to the last-mentioned path.
Another object is to provide an apparatus which will, in addition to the visual swing corrective path, define a second path visible to the golfer intersecting with the first path extending in the direction of intended flight of the ball and along which the ball may be teed at a point spaced forwardly of the intersecting portions of the paths.
Yet another object of this invention is to provide a panel member having means defining the aforementioned paths with the second path generally paralleling and spaced slightly inwardly of one edge portion of the panel member in order that the panel member edge portion may be utilized as a guide for correct positioning of the golfers feet relative to the paths defined by the panel member and the location in which the ball is to be teed.
A still further object of this invention, in accordance with the immediately preceding object, is to provide a panel member which may be readily altemately produced in a first manner adapting the panel member for outdoor use and a second manner adapting the panel for indoor use.
A final object of this invention to be specifically enumerated herein is to provide a golf swing corrective apparatus in accordance with the preceding objects which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble free in operation.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
HO. 1 is a perspective view of a first form of the invention constructed in a manner so as to be adapted for outdoor use;
H6. 2 is an enlarged vertical sectional view taken substantially upon the plane indicated by the section line 2-2 of FIG.
FIG. 3 is a plan view of a second modified form of the invention constructed so as to be adapted for indoor use; and
H6. 4 is a fragmentary vertical sectional view on somewhat of an enlarged scale and taken substantially upon the plane indicated by the section line 4-4 of FIG. 3.
Referring now more specifically to the drawings, and to FIGS. 1 and 2 in particular the numeral 10 generally designates a first form of the invention including a generally rectangular panel member 12 constructed of any suitable flexible and resilient material such as rubber. The panel member 12 is adapted to be spiked to the ground 14 by means of suitable headed spikes l6 driven into the ground 14 through openings (not shown) formed in the four marginal edge portions of the panel member 12.
The panel member 12 has first and second elongated openings 18 and 20 formed therein which are generally straight an intersect at one pair of corresponding end portions. The opening 20 generally parallels and is spaced slightly inwardly of one edge portion 22 of the panel member an the opening 18 diverges away from the opening 20 at its forward end 24,
In use, the panel member 12 may be either loosely laid upon the ground 14 or spiked thereto by means of spikes 16 with the opening 20 extending in the path of intended flight of a tee shot. The ball 26 to be used in the tee shot is teed up on a tee 28 piercing the ground at a point generally centrally intermediate the opposite ends of the opening 20 and centered transversely of the opening 20. The golfer 30 then stands along the edge portion 22 with his feet closely adjacent the edge portion 22 and spaced equally on opposite sides of an upstanding plane passing through the ball 26 and disposed normal to the longitudinal axis of the opening 20 and the edge portion 22. Then, as the golfer 30 swings his club 32 during the tee shot, as the golfers hands 34 approach the bottom portions of the arcs through which they are swung and the golfers body begins to pivot the golfer 30 attempts to have his hands 34 swing out and through along the opening 18, as viewed by the golfer 30. In this manner, the golfer's hands, during that portion of the golfers stroke during which the head 36 of the club 32 impacts with the ball 26, will swing through a vertical plane generally paralleling the longitudinal centerline of the opening 20 with the result that the head 36 of the club 32, during that portion of its swing in which it impacts with the ball 26, moves in a vertical plane extending longitudinally of the opening 20 and in which the ball 26 is contained, thus hitting the ball 26 squarely.
While the apparatus consisting of the first form of the invention 10 does not positively guide the golfers hands 34 in the above set forth manner, the golfer is visually aware of the opening 18 inasmuch as the ground 14 is of a different color than the upper surface of the panel member 12 and therefore the golfer 30 is provided a guide along which he may readily attempt to have his hands 34 move. Of course, after the correct swing is learned by the golfer 30, repeated practice of the swing while using the apparatus 10 will strongly impress upon the golfer 30 the feeling" of a correct swing and the apparatus 10 will subsequently be no longer needed.
With attention now invited more specifically to FIGS. 3 and 4 of the drawings there may be seen a second form of the invention generally referred to by the reference numeral 40 which includes a panel member 42 similar to the panel member 12 but which is secured to a suitable panellike base 44 by threaded fasteners 46 secured through the the panel member 42 and into the base 44. The base 44 may either be placed directly on the ground or used inside and placed upon a floor surface.
Generally straight stripes or paths 48 and 50 corresponding to openings 18 and 20 are defined on the upper surface of the panel member 42 either by a distinctive color paint or distinctive color strips recessed into the upper surface area of the panel member 42 and the latter includes a slot 52 upwardly through which a resilient support member 54 projects. The support member 54 is vertically short and includes a concave upper end face 56 for cradling a golf ball 58 on the upper end of the support member 54 so as to elevate the ball 58 above the upper surface of the panel member 42 in the same manner in which the ball 26 is elevated above the ground 14. Of course, the distinctively colored paths or areas 48 and 50 serve the same purpose as the openings 18 and 20 and therefore it may be seen that the second form of the invention 40 may be used in the same manner in which the first form of the invention is used.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
