Golf club measuring apparatus

An apparatus for measuring the angle deviation from a standard elevation angle between a golf club shaft and the underlying surface in order to assure a parallel relation between the sole of the golf club head and the underlying surface when the club is grasped by a golfer in a ball-addressing position;

• the apparatus comprising:
• a golf club shaft simulation member having at least a portion of an actual club shaft with a grip end and an affixed end;
• a hinge member for rotation through an angle of pre-selected range, the affixed end of said simulation member being attached to said hinge members for rotation therewith;
• a pointer also attached to said hinge member for rotation therewith and extending from said hinge member at a selected angle relative to said simulation member whereby rotation of said simulation member produces corresponding rotation of said pointer;
• indicating means cooperating with said pointer for displaying the angle between said simulation member and the surface underlying said apparatus whereby said angle deviation may be measured;
• and
• said simulation member having a yoke at said affixed end.

An apparatus for indicating the angle at which a golfer holds a golf club shaft relative to the ground;

• the apparatus comprising:
• a simulated golf club shaft rotatably connected at one end for rotation in a vertical plane and a display member connected to said shaft and calibrated to display the angle of said shaft in said plane relative to the ground;
• said display member having a pointer configured in a fixed angular relation to said shaft;
• said display member also having angle indicating indicia;
• and
• a housing into which said pointer extends, said housing having a face of which at least a portion is transparent for permitting observation of said pointer.
