Filed:

Appl. No.:

6/620036

International Classification:

A63B 6936

US Classification:

Abstract:

Golf pronation training device (10) is composed of a thin, flat airfoil (18) and a pair of flanges (21) formed with slotted bores (30) for receiving therein a shaft of a golf club. A plurality of thumbscrews (42) extend through the flange (21) to engage insert members (44) mounted on the flanges to lock the golf club shaft within bore (30) at a selected location along the length of the shaft and at desired angular orientation relative to the face of the club shaft. The effective area of airfoil (18) may be altered by selectively removing plugs (58) disposed within circular openings (56) spaced about the area of the airfoil. The training device (10) imparts a progressively increasing torque load on the club during the down swing tending to rotate the club head relative to the longitudinal axis of the club shaft to facilitate proper pronation of the golfer's hands. After the club strikes the ball, the continued rotation of the airfoil (10) results in a rapid decline of the air drag, thus enhancing the tendency of the golfer to follow through with his swing.

Abstract:

An integral hull and module system (10) includes a universal hull (12) configured to conveniently accept various modules (100) to convert the system (10) to different operational functions. Hull (12) includes an inner hull structure (24) for downwardly, slidably receiving the outer shell (102) of module (100) which is common to each module (100). To facilitate insertion of module outer shell (102) within inner hull structure (24), the side and end walls (126, 128 and 130) of the module outer shell are sloped inwardly to match the slope of side walls and end walls (26, 28, 30) which compose the sides of inner hull structure (24). Vertical keys (138) are formed on the exterior portions of the side walls of module outer shell (102) to slidably engage within corresponding keyways (42) formed in the side and end walls of inner hull (24) to properly align and prevent lateral movement of module (100) relative to hull (12).
