Abstract
Abstract Disclosed is a device for training a golfer to make a correct, repetitive swing. The device includes a harness adapted to be adjustably fitted about the shoulders and chest of the user to provide a means from which there depends a resiliently extendable, V-shaped suspending assembly for a training club of the type having a contoured training grip and a shaft of abbreviated length fitted at its lower end with a spherical weight. The V-shaped suspending assembly includes a pair of downwardly converging, elastic straps or suspension cords the upper, divergent ends of which are connected to the harness at widely spaced locations on the wearer's chest. In a preferred embodiment, one of the elastic elements is greater in length than the other, so that the V-shaped suspending assembly is asymmetrical. As a result, both elements are maintained at substantially the same tension in critical areas of the swing. During the swing, the suspension elements are tensioned to varying degrees, thus permitting one to "feel" the extent to which he is adhering to, or perhaps departing from, the several fundamentals of a sound swing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
306 words
A device for training a golfer in the fundamentals of the golf swing, comprising: (a) harness means adapted to be fitted to the golfer's upper body, said harness means including a chest strap extending around the golfer's chest at a location roughly midway between the golfer's shoulder and waist, said means further including shoulder straps connected to the chest straps and limiting the chest strap against movement downwardly from said location; (b) a club having an upper end provided with a grip and having a weighted lower end; and (c) means for suspending the club from said harness means, including a pair of downwardly convergent, resiliently extensible, flexible element having upper ends connected to said chest strap at connection points approximately equidistant from an imaginary line vertically bisecting the harness means, said connection points being spaced transversely of the chest when the strap is worn and being respectively disposed adjacent the upper portions of the golfer's arms when the golfer's hands are extended about said grip and the golfer has assumed an address position, said elements having lower ends connected to the upper end of the club, said elements being arranged to extend along both arms of the golfer when the golfer grips the club and being thereby adapted to be placed under varying degrees of tension relative to each other at different stages of a golf swing responsively to the positions of the hands and arms and the relative straightness of the arms at different stages beginning with the address position and continuing through the golfer's backswing, downswing, and follow-through, whereby to indicate an adherence to swing fundamentals through visual observation and through feel both with respect to the extent that changes in the relative tension of the elements are developed during the swing, and the stage of the swing at which said changes occur.
Claim 2
Independent Claim
306 words
A device for training a golfer in the fundamentals of the golf swing, comprising: (a) harness means adapted to be fitted to the golfer's upper body, said harness means including a chest strap extending around the golfer's chest at a location roughly midway between the golfer's shoulder and waist, said means further including shoulder straps connected to the chest straps and limiting the chest strap against movement downwardly from said location; (b) a club having an upper end provided with a grip and having a weighted lower end; and (c) means for suspending the club from said harness means, including a pair of downwardly convergent, resiliently extensible, flexible element having upper ends connected to said chest strap at connection points approximately equidistant from an imaginary line vertically bisecting the harness means, said connection points being spaced transversely of the chest when the strap is worn and being respectively disposed adjacent the upper portions of the golfer's arms when the golfer's hands are extended about said grip and the golfer has assumed an address position, said elements having lower ends connected to the upper end of the club, said elements being arranged to extend along both arms of the golfer when the golfer grips the club and being thereby adapted to be placed under varying degrees of tension relative to each other at different stages of a golf swing responsively to the positions of the hands and arms and the relative straightness of the arms at different stages beginning with the address position and continuing through the golfer's backswing, downswing, and follow-through, whereby to indicate an adherence to swing fundamentals through visual observation and through feel both with respect to the extent that changes in the relative tension of the elements are developed during the swing, and the stage of the swing at which said changes occur.
Claim 3
Dependent Claim
33 words
A golf swing training device as in claim 1 wherein the lower ends of the elements meet at the connection thereof to the club to impart a V-shaped configuration to the suspension means.
Claim 4
Dependent Claim
72 words
A golf swing training device as in claim 2 wherein one of said elements, in the untensioned condition of the elements, is visibly shorter in length than the other element whereby to impart a clearly asymmetrical form to the V defined by the elements to an extent effective to distinctly locate the apex of the V, and the club depending therefrom, closer to one of said connection points than to the other.
Claim 5
Dependent Claim
29 words
A golf swing training device as in claim 3 wherein the shorter element is the rear element in the sense of the direction in which the club is swung.
Claim 6
Dependent Claim
80 words
A golf swing training device as in claim 1 wherein said grip is contoured to require that one's hands and fingers are correctly placed thereon, the connection of said elements to the grip being disposed relative to the contouring of the grip to provide a visual reference for orienting the grip and hence the golfer's hands correctly in respect to said harness means and suspending means when the golfer has assumed the address position preliminary to swinging of the club.
