Abstract

Abstract A device is provided for training a player to maintain a fixed head position during the golf swing. The device employs a first element having a head portion formed on an elongated shank that is adapted to be inserted in the ground, and a second element that is apertured for adjustable disposition on the first element shank. In use, the first element shank is inserted in the ground so that the head portion thereon is viewed by a player in alignment with the shank axis when he assumes his stance for a swing, and the second element is adjusted along the shank axis to a disposition at which it is just obscured by the head portion when the latter is viewed from the assumed stance of the player. The first element head portion and the second element are relatively shaped in outline so that parallax and apparent size phenomena allow the second element to remain obscured during the golf swing only as long as a fixed head position is maintained. In particular, one of the outlines, preferably that of the first element head portion, is made oval and the other is made circular to provide the desired relation, and the second element is preferably invested with sharply contrasting surface coloring to provide a readily apparent signal of deviation in head position.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 211 words
Training apparatus for golfers comprising the combination of a supporting surface on which a golfer may stand and address a gold ball, a golf ball positioned at a predetermined point on said surface, and a golfer''s head movement indicator fixed to said surface adjacent said golf ball, said indicator comprising a first element having a head portion formed on the upper end of an elongated shank, and a second apertured disclike element adjustably disposed on the shank of said first element below said head portion, said first element being positioned at an inclination relative to said surface such as to permit a golfer''s line of sight, while the golfer is addressing said golf ball on said surface, to be substantially in alignment with the longitudinal axis of said shank, and the relative sizes and dispositions of said first element head portion and said second element being such that said second element is just obscured from the golfer''s line of sight while addressing said golf ball as aforesaid whereby, when executing a golf club swing, at said golf ball, improper movement of a golfer''s head will become evident to the golfer by the golfer''s line of sight being shifted to an extent as to bring the second element into the gOlfer''s view.
Claim 2
Dependent Claim 211 words
Training apparatus for golfers comprising the combination of a supporting surface on which a golfer may stand and address a gold ball, a golf ball positioned at a predetermined point on said surface, and a golfer''s head movement indicator fixed to said surface adjacent said golf ball, said indicator comprising a first element having a head portion formed on the upper end of an elongated shank, and a second apertured disclike element adjustably disposed on the shank of said first element below said head portion, said first element being positioned at an inclination relative to said surface such as to permit a golfer''s line of sight, while the golfer is addressing said golf ball on said surface, to be substantially in alignment with the longitudinal axis of said shank, and the relative sizes and dispositions of said first element head portion and said second element being such that said second element is just obscured from the golfer''s line of sight while addressing said golf ball as aforesaid whereby, when executing a golf club swing, at said golf ball, improper movement of a golfer''s head will become evident to the golfer by the golfer''s line of sight being shifted to an extent as to bring the second element into the gOlfer''s view.
Claim 3
Dependent Claim 35 words
A training device for golfers as defined in claim 1 and further characterized in that one of said first element head portion and said second element is oval in outline and the other is circular.
Claim 4
Dependent Claim 77 words
A training device for golfers as defined in claim 1 and further characterized in that said first element head portion is oval in outline, in that said second element is centrally apertured and is circular in outline, and in that the major axis of said head portion outline is sufficiently greater than, and the minor axis sufficiently less than, the diameter of said second element outline to provide said obscuring relation to the former to the latter.
