Abstract

Golf swing wrist action training apparatus having a leg mounted on a golf club in the area of the player'"'"'s hands; the leg lies on the off-target side of the shaft and angles sidewise outwardly and endwise upwardly to a point about opposite the juncture of the player'"'"'s hands on the club. This locates the upper contact end of the leg (in the ball address position of the club) spaced outwardly from the hands in an off-target direction with the shaft extending forwardly from the player'"'"'s forearms. When the player'"'"'s hands on the backswing reach about hip level, he cocks his wrists in an off-target direction moving the shaft from the forewardly extending position relative to his forearms to a near right angle position relative to his off-target forearm. This wrist pivot of the shaft swings the attached leg in an arc and brings the contact end of the leg into engagement with the off-target forearm of the player. This shows the player he has fully cocked his wrists. A sound signal "clicker" device is actuated at the contact end of the leg and emits a "click" signal upon a full wrist cock. Upon downswing uncocking of the wrists, the "click" signal again emits at the point of the uncocking. Also, should the player relax his wrist cock inadvertently, the "click" signal so advices him.

Claims

1. Golf swing training apparatus to demonstrate the addition of the wrist swing of the club to the arm swing of the club by cocking the wrists during the backswing to pivot the shaft at his hands from a near straight angle relative to his forearms to a near right angle relative to his off-target forearm so when the club head is moving at arm swing velocity in the downswing the wrists can be uncocked to add the velocity of the wrist swing to the velocity of the arm swing at the club head on impact with the ball, comprising,

a leg mountable on a club shaft;

said leg having a forearm contact upper end for contacting a player'"'"'s off-target forearm;

a lower end on said leg for attachment to a club shaft;

an intermediate portion on said leg between said upper end and said lower end;

3. In apparatus as set forth in claim 1, a signal device on said contact end;

said signal device emitting a signal upon being engaged with a player'"'"'s forearm when the wrists are cocked to provided the player with added indication that said contact end is in engagement with his forearm.

4. In apparatus as set forth in claim 1, motion means on said leg movably mounting said contact end;

said contact end being movable via said motion means between an exended position and a depressed position;

spring means biasing said motion means to locate said contact end in the extended position;

said contact end thereby being resiliently movable from said extended position to said depressed position by forcing said contact end against the playerd'"'"'s forearm when the wrists are cocked indicating to the player that said contact end is in engagement with his forearm.

5. In apparatus as set forth in claim 3, a signal device on said leg engageable by said contact end to emit a signal when said motion means are moved to the depressed position to provide added indication to the player that said contact end is in engagement with his forearm.

6. In apparatus as set forth in claim 3, said motion means comprising a plunger resiliently urged to said extended position by said spring.

7. In apparatus as set forth in claim 3, said motion means comprising pivotal hinge means resiliently urged to said extended position by said spring.

2. mounting means on said lower end for attaching said leg to a club shaft;

said lower end of said leg being mounted on a club shaft spaced below both hands of a player when gripping the club with both hands;

said leg when mounted lying in a plane normal to the plane of the club face in a direction opposite to the target direction,

said leg when mounted inclining from said lower attached end sidewise outwardly and upwardly in the off-target direction to said upper end;

said intermediate portion being of a length to locate said upper end at point approximately opposite the juncture of the player'"'"'s hands when gripping the club in the ball address position;

the angle of inclination of said leg being such to locate said upper end spaced sidewise outwardly of a player'"'"'s hands in an off-target direction a distance sufficient to avoid touching the player'"'"'s hands during his swing of the club at a ball;

when a player cocks his wrists on his backswing, the angle of inclination of said leg locating said upper end in the area of the off-target forearm of the player for contacting the off-target forearm of the player;

the angle of inclination of said leg relative to a club shaft and the length of said intermediate portion of said leg being coordinated to put the said upper end into contact with the off-target forearm of a player when the cock of his wrists angularly positions the club shaft approximately normal to a player'"'"'s off-target forearm;

when a player cocks his wrists on the backswing, he pivots the shaft from a near straight angle relative to his forearms of the address position to a near right angle position relative to his off-target forearm in the backswing position and said leg on the shaft swings withf the shaft and said contact end of said leg moves from a position sidewise of and below the player'"'"'s forearm into engagement at a near right angle with the player'"'"'s off-target forearm and shows the player that he has cocked his wrists;

when a player does not cock his wrists, he is shown by lack of engagement by said contact end of said leg with his off-target forearm that he has failed to cock his wrists.
