Abstract
A shaft for use in a golf-club or other shaft-based instrument, including a base member and a metal layer, and a method of making the same.
Claims43
A golf club shaft for use with a golf club head including a hosel having a predetermined length, the golf club shaft comprising:
- a polymer base member defining a tip end, a tip section adapted to be inserted into the hosel, a main body section, a grip section, and a butt end;
- and
- a metal layer extending around and secured to at least a portion of the base member tip section and defining distal and proximal ends, the metal layer being located such that the distal end of the metal layer is less than the predetermined length from the tip end and the proximal end of the metal layer is greater than the predetermined length from the tip end.
A golf club shaft, comprising:
- a base member including a plurality of fiber reinforced resin layers and defining a tip end, a cylindrical tip section, a frusto-conical main body section, a grip section, and a butt end;
- a metal layer extending around the base member, the metal layer including a cylindrical portion positioned around the tip section and a substantially frusto-conical portion positioned around the main body section extending from the tip section to an area within the main body section short of the grip section;
- and
- a bonding layer between the base member and the metal layer.

A shaft for use in a shaft-based instrument, comprising;
- a tubular base member including a plurality of fiber reinforced resin layers;
- and
- a metal layer wrapped around at least a portion of the base member.
A method of making a shaft for use in a shaft-based instrument, comprising the steps of:
- forming a tubular polymer base member;
- providing a metal sheet defining a surface;
- and
- wrapping the metal sheet around the base member.

A golf club, comprising:
- a golf club head including a hosel having a predetermined length;
- and
- a golf club shaft, including
- a polymer base member defining a tip end, a tip section having at least a portion within the hosel, a main body section, a grip section, and a butt end,
- a metal layer extending around and secured to at least a portion of the base member tip section and defining distal and proximal ends, the metal layer being located such that the distal end of the metal layer is less than the predetermined length from the tip end and the proximal end of the metal layer is greater than the predetermined length from the tip end.
