56265298, May 6, 1997

Filed:

Sep 18, 1995

Appl. No.:

8/530779

Inventors:

Paul A. Roy - Poway CA

Assignee:

Vantage Associates, Inc. - San Diego CA

International Classification:

A63B 5310

US Classification:

473319

Abstract:

A golf club shaft having a high modulus of elasticity in the grip end of the shaft to enhance stiffness, and a low modulus of elasticity in the tip end of the shaft to provide flexibility, and a method of manufacturing such a golf club shaft is disclosed.

Appl. No.:

6/034414

Inventors:

Paul A. Roy - Poway CA

Assignee:

Aldila, Inc. - San Diego CA

International Classification:

A63B 5310

US Classification:

273 80B

Abstract:

Presented is a golf shaft designed to have a "kick" point or "flex" zone at a predetermined location along the length of the shaft. How and where the shaft bends or flexes during the down swing has a strong influence on how the club "feels" to the golfer. How and where the shaft bends during the down swing is determined by the construction of the golf shaft and presented herewith is a golf shaft structure and method of making it which controls the position of the flex point along the length of the shaft so that a variety of shafts having different flex characteristics may be manufactured to suit the dictates of individual players.

Appl. No.:

7/211462

Inventors:

Paul A. Roy - Poway CA

Assignee:

Fiber-Speed International, Inc. - Naples FL

International Classification:

A63B 5310

US Classification:

156189

Abstract:

A golf club shaft of increased playability and feel is manufactured with a generally hollow and tapered cylindrical wall comprised of a plurality of layers of fibers and a resin binding the plurality of layers of fibers together into an integrated structure. The shaft includes a portion of constant outer diameter adjacent one end adapted to accept a grip and a portion of a smaller constant diameter adjacent the other adapted to be fitted to the hosel of a club head and a portion intermediate the two end portions with a uniformly tapering diameter. The golf club comprises a plurality of layers of fibers arranged and oriented within the shaft to resist torsional deflection and to provide a controlled and variable flexural resistance, permitting the player to recover energy stored in the shaft during the swing and to apply that energy to the ball for greater distance. The inner and outer layers of fibers include fibers running both perpendicular and parallel to the longitudinal axis of the shaft. The central layers include fibers running longitudinally along, or spiralling at a selected angle around, the axis of the shaft.
