Abstract
A golf club shaft having a main body section and a grip section associated with the proximal end of the main body section. The grip section includes a top hand portion, a bottom hand portion and a substantially cylindrical bottom thumb portion. Alternatively, or in addition, a kick section may be provided between the grip section and main body section.
Claims28
A golf club shaft, comprising:
- a main body section defining a distal end and a proximal end;
- and
- a grip section associated with the proximal end of the main body section, the grip section including a top hand portion, a bottom hand portion and a substantially cylindrical bottom thumb portion, the top hand portion being one of substantially cylindrical and, tapered and the bottom hand portion being the other of substantially cylindrical and tapered, the top and bottom hand portions each being at least one inch in length, and the tapered portion having a substantially continuous taper.
A golf club shaft, comprising:
- a main body section defining a distal end and a proximal end;
- a grip section associated with the proximal end of the main body section, the grip section defining a distal end and including a top hand portion, a bottom hand portion and a substantially cylindrical bottom thumb portion, the top hand portion being one of substantially cylindrical and tapered and the bottom hand portion being the other of substantially cylindrical and tapered;
- and
- a kick section between the distal end of the grip section and the proximal end of the main body section;
- wherein the grip section defines a distal end outer diameter, the main body section defines a largest main body section outer diameter, the kick section defines a smallest kick section outer diameter, and the smallest outer diameter of the kick section is less than grip section distal end outer diameter and the largest main body section outer diameter.
