1. A golf club shaft comprising:
- at least one tubular section; and
a unitary insert attached to said at least one tubular section for regulating the flex point of said shaft, said insert being shorter than said tubular section and having a central section and a pair of couplers integrally formed on opposite ends of said central section, at least one of said couplers being attached to an end of said tubular section of the shaft and the central section extending axially outwardly away from the end of said tubular section, said insert being at least as rigid as said tubular section.

Abstract
Golf clubs, golf shafts, and inserts for golf club shafts have a coil or coil-type insert for enhancing swing weight control, stiffness and flex control, shock absorption and vibration elimination or reduction. The insert has a central section and a pair of couplers integrally formed on opposite ends of the central section to attach to the shaft or club head.

30. A golf club comprising:
-
a golf club head;
a shaft having upper and lower tubular sections, one tubular section connected to the golf club head and the other tubular section connected to a grip; and
means for regulating the swing weight, flex point, and stiffness of the club, said means including a unitary insert having a central section and a pair of couplers integrally formed on opposite ends of said central section, one coupler attached to the upper tubular section of the shaft and the other coupler attached to the lower tubular section of the shaft, said insert being at least as rigid as said tubular sections. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)

42. A golf club shaft having a distal end and butt end, comprising:
-
a tubular section including a first end located at the butt end of the golf club shaft and a second end positioned slightly short of the distal end of the golf club shaft;
an unitary insert secured to the second end of the tubular section, the insert being shorter than the tubular section, the insert extends from the second end of the tubular section to the distal end of the golf club shaft and includes a tubular first end securely coupled to the second end of the first member and a tubular second end shaped and dimensioned for secure attachment within a hosel of a golf club head;
the insert being formed from a vibration absorbing material which absorbs undesirable vibrations resulting from an individual striking a golf ball. - View Dependent Claims (43, 44, 45, 46)

47. A golf club shaft having a distal end and butt end, comprising:
-
a tubular section including a first end located at the butt end of the golf club shaft and a second end positioned slightly short of the distal end of the golf club shaft;
a unitary semi-rigid insert secured to the second end of the tubular section, the insert being shorter than the tubular section, the insert extends from the second end of the tubular section to the distal end of the golf club shaft and includes a tubular first end securely coupled to the second end of the first member and a tubular second end shaped and dimensioned for secure attachment within a hosel of a golf club head;
the insert being formed from a material controlling the stiffness at the distal end of the golf club shaft upon striking a golf ball to thereby stabilize a golf club head secured to the distal end of the golf club shaft. - View Dependent Claims (48, 49, 50, 51)
