2 Claims. (01. ,27s 35) This invention relates to golf practice devices and more particularly to a device for holding the golfers arms in proper relationship during practice or even in playing the game.
It is well known among those acquainted with the game of golf that proficiency in the game is acquired largely by the development of a consistent swing so that the head of the club will contact the golf ball squarely while traveling at the greatest possible speed in the direction of the balls desired line of flight. Teachers of the game have stressed the importance of a proper rhythm, grip and stance during the stroke and, among other things, have emphasized the necessity for developing a desired coordination between the arms while swinging the club toward the ball and during the follow through subsequent to striking the ball. It has been found that this coordination may best be acquired by keeping the elbows comparatively close together during the entire stroke so that the arms, hands, and the body will work together to give increased power and accuracy to the stroke.
To assist golfers in developing such coordination, I have devised the present device which may be attached to the arms of a player above the elbows to prevent too great separation of his elbows as he swings the club. By use of the device while practicing or, if desired, when playing the game, he will develop the habit of keeping his elbows close enough together to groove his stroke and thus improve his game.
An object of my invention is to provide a device for this purpose which is adjustable to fit arms of different size and which may be easily applied, whereby the users elbows will be retained within a predetermined distance of each other without hindering the proper arm action during the swing.
Another object of the invention is to provide in such a device means for readily attaching the part of the device on one arm to the part on the other before use and detaching them after use.
Other objects and advantages of the invention will be apparent from the following description of a preferred embodiment thereof, taken in con- 2 Each of said buckles has a prong I5 thereon adapted to enter any one of a plurality of holes I6 in the opposite end portion of the strap on which such buckle is carried, whereby said straps may be formed into two separate closed rings of adjustable circumference as illustrated in the in place.
Rings I1 and I8 may be secured respectively to said straps in any desired manner, as, for example, by the use of strips I9 stitched to said straps. A link 26 is attached to said ring I1, and a spring snap 2I, engageable with the ring I8 is attached to said link by means of a swivel 22 whereby said straps I I and I2 may be readily secured to each other.
Elastic arm-gripping members 23 and 24 are attached at their ends to the straps II and I2, respectively, by stitching 25. Said members comprise two sections 26 and 28 adjustably connected together by a clasp 21 carried on the free end of the section 26 and adapted to receive the free end of the section 28. By sliding the latter through said clasp a ring of desired circumference may be formed consisting of a portion of the strap II or I 2 on one side and the associated gripping element 23 or 24 on the other.
To apply the device the ring I8 is released from the snap 2I and each of the buckles and clasps is opened or loosened. In this condition the straps are placed on the right and left arms just above the elbows and are there secured by slipping the sections 28 of the members 23 and 24 through the clasps 21 until said rings II, 23 and I2, 24 fit snugly enough about the arms to hold the device The ends of the straps II and I2 may be adjusted in the buckles I3 and I4 before or after the grips are set and will be loose enough to permit the necessary freedom of muscular action. The snap 2| may then be engaged with the ring I8 and the maximum distance by which said elbows may be separated will thus be limited by the straps II and I2 and the linkage therebetween. If, upon trial, this distance is found to be too great or too small, the necessary adjustment may be made by adjusting the strap ends in the buckles I3 and I I.
It will be evident from the above description that the device may be adjusted to fit arms of any size by adjustment of the sections 28 of the gripping elements 23 and 24 in the clasps 21. Also, because of the elasticity of the members 23 and 24, and because the circumference of the loops formed by the straps is substantially greater than that of the arms, it will be seen that the device may be comfortably retained on the arms at all times during practice or play without undue binding in any position, It will furthermore be apparent that a player wearing the device may quickly and easily connect the snap 2| to the ring it; or disconnect it therefrom so that relative movement of his arms will not be restricted except while he is practicing, or while he is making a stroke if he wears the device when playing a game. The principal use of the device of course will be in practice.
The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.
1. A golf practice device comprising: a plurality of straps, one adapted to form a closed loop loosely positioned about one arm in the proximity ofits elbow and another to form a like loop about the other arm; elastic members, at least one of which is attached to each of said loops to form a ring within the latter adapted to fit snugly about the arm for holding said loop inplace; and means joining said loops for limiting the distance by which the arms may be separated from each other while making a golf stroke.
2. A golf practice device comprising: a plurality of straps, one adapted to form a closed loop loosely positioned about one arm in the proximity of its elbow and another to form a like loop about the other arm; adjusting means for varying the size of said loops; elastic members, at least one of which is attached to each of said loops to form a ring within the latter adapted to fit snugly about the arm for holding said loop in place; adjusting means for varying the size of said rings; and means for joining said loops for limiting the distance by which the arms may be separated from each other While making a golf stroke.
