Abstract
Abstract A tubular member defining a shield is formed of a pliable yet resilient plastic split along one side of its length. The cross section of at least one end is selectively tapered to provide an extended end portion at the extreme end of the tapered cross section. The extended end portion facilitates the pressing of the split tubular member onto a selected length of a graphite shaft of a golf club, to prevent wear on the graphite shaft by the divider sections of a golf bag when the clubs are being carried in the bag.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
189 words
A golf club shaft shield for protecting a golf club shaft, which shield includes an end portion configuration which initiates the ready attachment of the shield to and from the shaft, comprising: an elongate tubular member terminating in opposing ends and having a centrally extending axis, a generally circular cross section and an overall length; at least one of said ends being formed into a tapered end means, said tapered end means having a taper formed at a preselected angle relative to said axis to terminate said tapered end means in an extended tip; wherein an axial line coincident with the extended tip of said tapered end means further defines said overall length; said elongate tubular member having a shortest length coaxial with and in generally diametrically opposed relation to, the axial line of the member; said elongate tubular member being split axially along said shortest length; and said extended tip of the tapered end means providing for initiating the spreading of the split in the tubular member to facilitate slipping said shortest length thereof over the shaft to provide said ready attachment of the shield to the shaft.
Claim 2
Dependent Claim
189 words
A golf club shaft shield for protecting a golf club shaft, which shield includes an end portion configuration which initiates the ready attachment of the shield to and from the shaft, comprising: an elongate tubular member terminating in opposing ends and having a centrally extending axis, a generally circular cross section and an overall length; at least one of said ends being formed into a tapered end means, said tapered end means having a taper formed at a preselected angle relative to said axis to terminate said tapered end means in an extended tip; wherein an axial line coincident with the extended tip of said tapered end means further defines said overall length; said elongate tubular member having a shortest length coaxial with and in generally diametrically opposed relation to, the axial line of the member; said elongate tubular member being split axially along said shortest length; and said extended tip of the tapered end means providing for initiating the spreading of the split in the tubular member to facilitate slipping said shortest length thereof over the shaft to provide said ready attachment of the shield to the shaft.
Claim 3
Dependent Claim
33 words
The shield of claim 1 wherein the tapered end means includes a generally elliptical annular surface and terminates in said extended tip of the member to define a generally flattened extended end portion.
Claim 4
Dependent Claim
28 words
The shield of claim 2 wherein the inside diameter of the tubular member is of a diameter which causes it to fit snuggly about the shaft when installed.
Claim 5
Dependent Claim
17 words
The shield of claim 2 wherein the tubular member is formed of a pliable yet resilient plastic.
Claim 6
Dependent Claim
46 words
The shield of claim 2 wherein both ends of the tubular member are formed at the preselected angle to define opposing tapered end means, said split being formed axially along the member's shortest length to be generally diametrically opposite to said longitudinal line of the member.
Claim 7
Dependent Claim
42 words
The shield of claim 2 wherein the tapered end means comprises a tapered end of gradually increasing angle towards the extended tip, said angle being of the order of from 20 degrees through 45 degrees relative to the axis of the member.
Claim 8
Dependent Claim
47 words
The shield of claim 2 wherein the tapered end means comprises a tapered end of at least two angles relative to the axis, wherein the flattened extended end portion has a smaller angle of taper relative to the axis of the member than a remaining tapered portion.
Claim 9
Dependent Claim
49 words
The shield of claim 2 wherein the tubular member has a selected wall thickness and the tapered end means includes a tapered end having a tapered annular surface of generally said selected wall thickness, said wall thickness being selectively back-beveled to lessen the ridge formed by the wall thickness.
