Carter, 2t) Westwood Road, Shrewsbury, Mass. Filed Aug, 4, 196i), Ser. No. 47,496 6 Claims. (Cl. 273-35) This invention relates to the game of golf and relates more particularly to practice apparatus whereby a golfer can easily observe his position of stance and -his movements as he hits the ball.
A person who plays golf usually tries to improve his game by instruction or by continued practice, or both. Much of this improvement is achieved by correcting his swing, grip, stance, etc. Most of the motions which an instructor tries to correct cannot be seen by the golfer himself who must try to visualize his mistakes. Such visualization is diihcult. Motion pictures are 'occasionally taken to obviate this diculty, but such pictures are too expensive and time-consuming to be generally practicable. It is, accordingly, most desirable that means be pro vided whereby a golfer can observe his movements while addressing and in actually hitting a ball, and so that he may, at the same time, keep his eyes focused on the ball, which is a basic tenet of good golfing.
The main object of this invention is, therefore, to provide apparatus for golf stance and swing analysis whereby a golfer can observe his movements and still focus his eyes on the ball during the swing as required by good practice.
In accordance with this invention, this and other objects are achieved by means of a novel golf practice device which comprises a mirror disposed near a golf tee,.
said tee and mirror being both within the normal range of vision of a golfer in position to hit a ball from said tee, and means for reflecting said golfers image onto said mirror, the mirror being so arranged that the entire image is Visible to the golfer whereby the golfer can study his position and movements while addressing and actually hitting the ball.
This invention will be better understood by reference to embodiments illustrated in the accompanying drawing wherein:
FIG. 1 is a side elevation illustarting a desirable and practical apparatus according to one embodiment of the invention and showing a golfer in side view;
FIG. 2 is a front elevation as viewe-d from the position of the golfer showing the large convex mirror and the frame which supports it;
FIG. 3 is a vertical section to larger scale substantially on the line 3 3 of FIG. 1;
FIG. 4 is a diagrammatic side View similar to FIG. 1 illustrating apparatus of `simpler form and graphically indicating the direction of the light rays by means of which the golfer is able to check the yaccuracy of his stance, as he would be observed from in front by an instructor;
FIG. 5 is a view similar to FIG. 4 but with the golfer i Referring first to FIGS. 4 to 7 of the drawings, the
simple embodiment therein -diagrammatically illustrated comprises a horizontal at or plane mirror 10 resting, for example, on the ground and disposed directly below a -golf tee 12, and an elevated, second mirror 14 supported by an upright frame 16. The mirror 14 has a convex surface 1S which is of such radius or curvature and so located, relatively to mirror 1t) and to the tee, that a ,l
golfer, standing, in relation to the tee as illustrated at 20, may see his full image in the mirror 10 as it is reected by mirror 14. This image reflection is graphically indicated in the drawings by lines 22 and 22a connecting the golfers eyes and the mirrors. The lines 22 and 22a are schematic and are provided merely to illustrate the function of the various mirrors which utilize well-known optical principles.
As the 4golfer stands in a position `as shown at 20, in readiness to hit a golf ball 24 placed on a tee, he is enabled by this apparatus, to keep his eye on the ball, as required by good practice, and at the same time to see his image and observe all of his movements in the mirror 1t), To aid in positioning himself properly in conformity to that which is theoretically correct, the mirror 10 may be provided with reference lines L (FIG. 6) or `other indicia in Vor on its surface, or such lines can be reflected onto the mirror surface. Such reference Ilines L (FIG. 6) may be of any ldesired conguration or arrangement, for example to constitute a grid or a simple pair of axes.
The Amirror 10 may, if desired, be located in a shallow chamber in the ground and directly beneath the tee, or it can be located in some other position adjacent to the tee where it is within the normal range of vision `of a golfer having his eyes focussed on the ball. If the mirror 10 be located under the tee 12 (as shown in FIG. 7), provision should be made to prevent damage to the mirror. For this purpose, the mirror 10 may be made of speculum metal or other polished and highly reflecting metal, so as to resist fracture, or the mirror may be covered by a protective screen. Thus, as shown in FIG. 7, a coarsemesh 'screen S, of ne wire, supports the tee 12,. As illustrated in FIG. 4, the golfer is so positioned relatively to the mirrors that, when addressing the ball, he sees himself in front view, while, when standing in the position of FIG. 5, with his side toward the mirror, the mirror 18 reflects that side of the golfer, which is thus exposed to the mirror and thus in the mirror 10 the golfer may obtain a side View of himself.
Referring now to FIGS. 1, 2 and 3, the commercial embodiment of the invention as illustrated comprises a low platform P upon which the golfer may stand while practicing. This platform is designed to rest on the ground or upon the floor of a suitable building and may, for example, be of the order of 3 in height, including a mat covering its upper surface and which may for example be of rubber to insure good footing. Assuming for convenience in description that the edge E (FIG. 1) of the platform, proper, is its front edge, the apparatus also comprises a casing C projecting forwardly from the edge E and fixed 4to or forming an integral extension of the platform proper and which need not be so wide transversely as the platform and which, if desired, may be slightly less in height than the platform, for example, by the thickness of the mat which forms the upper surface of the platform. As shown in FIG. 1 that portion of the top of the casing C which is next adjacent to the edge E of the platform provides a support for the golf ball and for this purpose may be provided with a mat K, for example, of rubber, or imitation grass, as preferred, or this portion of the casing may be provided with means for receiving a conventional golf tee. Alternatively, the ball may be supported upon the platform proper, just to the rear of edge E. The casing C has an internal cavity or well W (FIG. 3) which is open at the top and within this cavity or well there is arranged a mirror 10a, corresponding in function to the mirror 10 previously referred to. In this commercial arrangement the mirror 10a is pivotally mounted to rock about an axis 3d parallel to the edge E of the platform. This axis is preferably somewhat further from that edge 31 of the mirror which is adjacent to the edge E of the platform than to the opposite edge. The edge 31 of the mirror rests upon an inclined surface 52 (FIG. 3) of a slidable wedge block 33 which slides in a guideway within the platform P. This wedge block is connected by a screw-thread to the front end of a rotatable rod or shaft 34 which extends to the rear of the platform and has attached to its rear end (externally of the platform) an actuating wheel 35 which, for example, may be provided with a rubber tire or may be 1of metal with a knurled edge. By placing his foot on the edge of this wheel 35 and moving it in one direction or the other, a golfer, standing on the platform, may rotate the shaft 34 and thus advance or retract the wedge block 33 and so rock the mirror 10a. A spring 36 beneath the mirror tends to turn the mirror in the counterclockwise direction, as viewed in FIG. 3.
As illustrated in FIG. l, a mirror 14a corresponding generally in function to the mirror 14 above described, is arranged forwardly of the casing C. This mirror inclines upwardly and forwardly and is attached at its lower edge to the casing C by a suitable bracket T. The forward, upper edge of the mirror is supported by a frame comprising spaced horizontal members 39 extending from the casing C, and Which are rigidly connected to the lower portions of two parallel upright legs 37 and 38. The convex surface 18a of mirror 14a is directed upwardly. The upper ends of the legs 37 and 38 are bent rearwardly to form supports for a third mirror 40. This latter rnirror is a plane mirror having its lower face inclined upwardly and rearwardly as referred to the forward edge E of the platform. Desirably this mirror 40 is iixed to the under side of a supporting plate 41 of substantial-ly larger diameter than the mirror and of opaque or non-refrecting material, this plate 41 being attached by suitable mechanical connections to the upper portions of the legs 37 and 38. Referring to FIG. l, the convex mirror, disposed at the angle shown, reflects an upright, full length, front-view image of the golfer to reduced scale, so that it falls on the plane ymirror 41. Because this is a plane mirror and inclined as shown, it reects the same image which it receives from mirror 18 down onto the mirror wherein the golfer sees himself from head to foot, as well as the golf ball, the head of the club relatively to the golf ball, and his hands gripping the club handle. By the use of the three mirrors, relatively arranged as described, the angle of incidence of the light rays is not so acute `as in the arrangement shown in FIGS. 4 and 5, and thus there is less distortion and a more lifelike image results. Merely by way of example of a practical arrangement, the plane mirror 10a may be 14 inches in diameter, the convex mirror 14a imayfbe 35.5" in diameter and of a radius of curvature of the order of 8 feet, and its inclination may be such that the plane which is perpendicular to the central radius of the mirror makes an angle of approximately 40 with the horizontal. The plane mirror 40 may be oval, for example 24" x 28 (with its major axis horizontal), and inclined upwardly and rearwardly at an angle of the order of 10 to the horizontal and with its upper edge disposed at an elevation of 58" above the level of the surface upon which the platform rests. The platform P may be of the order of 4 feet square and the casing C may be approximately 27 inches in transverse width and extend forwardly a distance of two feet from the front edge E of the platform proper. The above suggested dimensions have been found to provide a thoroughly practical arrangement without necessitating the mounting of either of the mirrors 14a or 41 `for adjustment, the dimensions being such that, regardless of the height of a person desiring to use the apparatus, he may, by moving from front to rear of the platform and by adjusting the inclination of the mirror 10a, rind a position such as to obtain a olea-r full length View of himself and of the ball and tee in the mirror 10a.
While the convex mirror 14a is here shown as fixedly supported, with its lower edge attached to the casing C and by a rlixed frame at its rear edge, it is contemplated that this mirror may be provided with independent legs (not here shown) so that it lmay be moved about independently Aof the other mirrors. Thus, for instance, it may be carried out onto a ygolf course and set up upon a green where the golfer may make use of it in observing his stance and in perfecting his swing, although such a simple mirror without the assistance of the other mirror or mirrors herein described does not provide the same perfection of view as when it is associated with another or other mirrors.
It may be noted that, in both embodiments illustrated, the various mirrors reflecting the golfers image to the tee 12. are `so disposed that they will not interfere with the swing of the golfers club.
While certain desirable embodiments of the invention have herein been disclosed by way of example, it is to be understood that the invention is broadly inclusive of any and al1 modifications falling within the scope of the appended claims and that wherein dimensions or materials have been cited by way of example, such dimensions or materials are not to be regarded as limiting, but only as helpful -in the design and use of apparatus embodying the invention.
