Golf swing training machine

Abstract

A golf swing training device, in which a golf club or golf club simulating device is propelled by the arms and hands of a person along a desired arcuate trajectory under an optimal amount of muscular force, maintains the hands of the user on a single optimal plane, while allowing the club to travel on a separate plane through a structure containing a plurality of rotational means allowing all necessary anatomically desireable movements. A movable user platform allows hysteresis in the swing when a user shifts their weight.

1 . A swing training device for practicing the propelling by a person's arms and hands of a club along a defined, arcuate trajectory of a given radius, above a ground plane according to a person's given height and arm length, said device comprising: 
 a stationary frame;    a first movable structure pivotable about a fist axis; supported by said frame;    a second movable structure pivotably attached to said first movable structure, rotatable about a second axis which is substantially parallel to said first axis;    a third movable structure pivotably supported by said second movable structure, rotatable about a third axis which is substantially perpendicular to said second axis; and,    means for retaining a club such that the club can freely rotate about a fourth axis which is substantially perpendicular to said third axis.    
   
   
       2 . The device of  claim 1 , which further comprises a simulated club, retained by said means for retaining; wherein said simulated club features a grippable portion, freely rotatable about said fourth axis.  
   
   
       3 . The device of  claim 1 , wherein said device further comprises means for adjustably resisting movement of at least one of said structures.  
   
   
       4 . The device of  claim 1 , wherein said device further comprises means for adjusting the height and slant of said trajectory in reference to said ground plane; and means for adjusting the radius of said trajectory.  
   
   
       5 . A swing training device which retains a club by an articulated structure such that the club can rotate about three axes, wherein each axis of rotation penetrates a grippable portion of the club; 
 said articulated structure being supported by a movable arm;    said movable arm supported by a stationary frame and rotatable about a fourth axis.    
   
   
       6 . The device of  claim 1 , wherein said device further comprises a movable user platform.  
   
   
       7 . The device of  claim 5 , wherein said device further comprises a movable user platform.
