Abstract
A one way action golf club flex modification system mounted within a golf club. The non-linear shape of the flex modification member engages the interior wall of the hollow shaft at two regions on opposite sides of the shaft interior and is affixed to a third point in the handle. The “free” end of the flex modification system is closest to the head and generally oriented toward the striking face of the head. The one way action reduces the flexibility of the shaft during the swing toward the golf ball but allows the shaft to flex forward with the travel of the ball. The plane described by the waive shape of the flex member may be fixedly rotated relative to the shaft to allow fine tuning to accommodate the individual swing of the golfer.
Claims6
A golf club assemble with adjustable shaft flex modifier comprising:
- a commercially available or custom built golf club having an elongated hollow shaft;
- said hollow shaft has a head end a length and an opposite handle end which is open;
- a tension rod;
- said tension rod having a proximal end, length and distal end and being made from material of a predetermined modulus of elasticity over its length and bent at a predetermined angle at a predetermined distance from said distal end;
- a turning bar;
- a locking means;
- a turning means
- said turning bar having a first end, a body and a second end;
- said body and at least said second end and some portion of said body defining a tension rod aperture adaptive to fixedly receive said tension rod proximal end and some portion of said length and said body outer surface defining a cylinder and said second end defining a depression or protrusion adaptive to engage ably receive said turning means and said body accommodating said locking means;
- a stop ring;
- said stop ring having a first end, a body and a second end;
- said first end and body defining an aperture adaptive to rotatably receive said turning bar and said second end defining a stop ledge aperture which is less than the aperture of said body and said stop ring body outer surface defining a profile concomitant to the inner profile of said golf club opposite handle end;
- a stop ring securing means;
- said securing means attaches said stop ring to said golf club shaft;
- said locking means selectable engaging said turning bar to said stop ring;
- and
- said stop ring mounted in said golf club handle end with said stop ring second end toward golf club head, said tension rod proximal end mounted in said turning bar, said tension rod inserted in said golf club shaft distal end first until said turning bar fully engages said stop ring, said turning bar rotated until said tension rod distal end is in a predetermined position relative to said head and said locking means engaged.
