Abstract

Abstract The inner sleeve joining the shaft of the golf club to the head projects but a small distance beyond the head and an outer sleeve of relatively stiff flexible materials forms in effect an extension of the inner sleeve and snugly embraces the shaft well beyond the inner sleeve. In this way, the shaft is allowed to flex along a greater extent of its length then would otherwise be possible.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 179 words
A wood-type golf club comprising a head, shaft and means operatively connecting said sahdt and head, said head comprising a toe, heel and sole portions, a top surface opposite said sole portion and a hitting surface therebetween: said top surface having a generally inclined generally flat mounting surface above said heel portion, said mounting surface being continuous from said top surface, and a shaft bore substantially normal to said mounting surface and extending toward said sole portion, said shaft bore inlcuding an upper counterbore communicating with said mounting surface; a first inner sleeve circumjacent to an intermediate portion of said shaft and generally complimentary to said counterbore in which it is disposed; said first sleeve including an enlarged upper portion overlying said mounting surface and in engagement therewith and a second sleeve circumposed about said enlarged upper portion of said first sleeve and lockingly engaged therewith; and said second sleeve having its lower end engaging said mounting surface and its upper end extending above said first sleeve enlarged portion and generally merging into the outer surface of the shaft.
Claim 2
Dependent Claim 179 words
A wood-type golf club comprising a head, shaft and means operatively connecting said sahdt and head, said head comprising a toe, heel and sole portions, a top surface opposite said sole portion and a hitting surface therebetween: said top surface having a generally inclined generally flat mounting surface above said heel portion, said mounting surface being continuous from said top surface, and a shaft bore substantially normal to said mounting surface and extending toward said sole portion, said shaft bore inlcuding an upper counterbore communicating with said mounting surface; a first inner sleeve circumjacent to an intermediate portion of said shaft and generally complimentary to said counterbore in which it is disposed; said first sleeve including an enlarged upper portion overlying said mounting surface and in engagement therewith and a second sleeve circumposed about said enlarged upper portion of said first sleeve and lockingly engaged therewith; and said second sleeve having its lower end engaging said mounting surface and its upper end extending above said first sleeve enlarged portion and generally merging into the outer surface of the shaft.
Claim 3
Dependent Claim 148 words
A wood-type golf club comprising a head, shaft and means operatively connecting said shaft and head: said head including toe, heel, sole and top surfaces with a hitting surface therebetween; said top surface including a generally flat inclined mounting surface continuous from said top surface and above said heel; said heel including a bore extending through said mounting surface and extending toward said sole, said means connecting said shaft and head comprising a pair of telescoped sleeves secured about an intermediate portion of said shaft, said shaft extending into said bore, an innermost one of said sleeves depending into said bore, and above said mounting surface and including anenlarged portion generally engaging said mounting surface, the other sleeve being connected to said enlarged portion and having a lower end engaging said mounting surface and an upper end connected to said enlarged portion and generally merging into said shaft.
Claim 4
Dependent Claim 148 words
A wood-type golf club comprising a head, shaft and means operatively connecting said shaft and head: said head including toe, heel, sole and top surfaces with a hitting surface therebetween; said top surface including a generally flat inclined mounting surface continuous from said top surface and above said heel; said heel including a bore extending through said mounting surface and extending toward said sole, said means connecting said shaft and head comprising a pair of telescoped sleeves secured about an intermediate portion of said shaft, said shaft extending into said bore, an innermost one of said sleeves depending into said bore, and above said mounting surface and including anenlarged portion generally engaging said mounting surface, the other sleeve being connected to said enlarged portion and having a lower end engaging said mounting surface and an upper end connected to said enlarged portion and generally merging into said shaft.
Claim 5
Dependent Claim 28 words
The structure as claimed in claim 2 including mechanical lock means extending transversely through said head and intermediate portions of said inner sleeve and shaft within said bore.
