Abstract

Abstract A golf club shaft having an axis, an inner wall and an outer wall, both axial, circular in cross section, a major portion of it adjacent to the club head tapering so as to narrow toward the head end of the shaft, the wall thickness thereby increasing. The shaft has throughout its entire length a substantially constant cross section area in planes normal to the longitudinal axis thereby providing uniform linear distribution of the shaft weight throughout its length. The shaft may be expanded beyond an extension of the taper to form a handle, to which a lightweight wrapping may be applied as a grip. A club head includes a body, a striking face on the body with an upper margin, and a hosel with a bore to receive the shaft extending below an extension of the upper margin.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 338 words
A conventional golf club comprising: a golf club shaft formed as a continuous, homogenous metal tube having a longitudinal axis, a circularly sectioned inner wall and a circularly sectioned concentric outer wall extending axially from a head end to a handle end of said shaft, both of said walls, throughout a tapered head end portion extending from the head end to a sUbstantial axial distance therefrom, and throughout a tapered handle end portion extending from a point adjacent to the handle end to a substantial axial distance therefrom, being continuously tapered, smooth and uninterrupted, and increasing in diameter, the wall thickness of the shaft thereby increasing in both of said head end portion and of said handle end portion as the shaft extends toward the head end, the shaft having throughout its entire length a substantially constant cross section area in planes normal to the longitudinal axis, thereby providing uniform linear distribution of the shaft weight throughout its length, the wall thickness at the head end being at least 250 percent that of the wall thickness adjacent to the handle end; a golf club head comprising a body, a striking face on said body having an upper margin which in elevation is sensibly straight in elevation view, and a hosel having a tapered bore with an axis extending transverse to an imaginary extension of the said upper margin, the top of the bore standing above said extension, and the bottom of the bore being closed and terminating above the bottom of the club head and below said extension, the walls of the bore and of the outer wall of the shaft adjacent to the head end being identically tapered, and the head end of the shaft being tightly fitted into and retained in said bore, a ribbonlike, flexible, thin, and lightweight wrapping wound around and upon the handle end portion, the diameter of the outer wall of the handle end portion being at least 225 percent that of the diameter of the outer wall at the head end.
Claim 2
Dependent Claim 338 words
A conventional golf club comprising: a golf club shaft formed as a continuous, homogenous metal tube having a longitudinal axis, a circularly sectioned inner wall and a circularly sectioned concentric outer wall extending axially from a head end to a handle end of said shaft, both of said walls, throughout a tapered head end portion extending from the head end to a sUbstantial axial distance therefrom, and throughout a tapered handle end portion extending from a point adjacent to the handle end to a substantial axial distance therefrom, being continuously tapered, smooth and uninterrupted, and increasing in diameter, the wall thickness of the shaft thereby increasing in both of said head end portion and of said handle end portion as the shaft extends toward the head end, the shaft having throughout its entire length a substantially constant cross section area in planes normal to the longitudinal axis, thereby providing uniform linear distribution of the shaft weight throughout its length, the wall thickness at the head end being at least 250 percent that of the wall thickness adjacent to the handle end; a golf club head comprising a body, a striking face on said body having an upper margin which in elevation is sensibly straight in elevation view, and a hosel having a tapered bore with an axis extending transverse to an imaginary extension of the said upper margin, the top of the bore standing above said extension, and the bottom of the bore being closed and terminating above the bottom of the club head and below said extension, the walls of the bore and of the outer wall of the shaft adjacent to the head end being identically tapered, and the head end of the shaft being tightly fitted into and retained in said bore, a ribbonlike, flexible, thin, and lightweight wrapping wound around and upon the handle end portion, the diameter of the outer wall of the handle end portion being at least 225 percent that of the diameter of the outer wall at the head end.
Claim 3
Dependent Claim 30 words
A golf club according to claim 1 in which the inner wall of the shaft is modified to include axially extending splines adjacent to the head end of the shaft.
Claim 4
Dependent Claim 30 words
A golf club according to claim 1 in which an adhesive is disposed between the wall of the bore and the outer wall of the shaft to bond them together.
Claim 5
Dependent Claim 30 words
A golf club according to claim 3 in which the wall of the bore and that part of the outer wall of the shaft which is contiguous thereto are imperforate.
Claim 6
Dependent Claim 28 words
A golf club according to claim 1 in which an untapered portion is contiguous to, continuous with, and interconnecting, the handle end portion and the head end portion.
Claim 7
Dependent Claim 30 words
A golf club according to claim 5 in which an adhesive is disposed between the wall of the bore and the outer wall of the shaft to bond them together.
Claim 8
Dependent Claim 30 words
A golf club according to claim 6 in which the wall of the bore and that part of the outer wall of the shaft which is contiguous thereto are imperforate.
Claim 9
Dependent Claim 17 words
A golf club according to claim 1 in which the shaft is made of an aluminum alloy.
Claim 10
Dependent Claim 17 words
A golf club according to claim 8 in which the club head is made entirely of metal.
