Abstract
An adjustable golf shaft having an upper shaft member, a lower shaft member and an inner rod. The upper shaft member includes an elongated bore therein with an upper bushing fixed within an upper end of the elongated bore therein. The lower shaft member has an elongated bore therein with a middle bushing fixed within an upper end of the elongated bore therein. The inner rod includes a lower end dimensioned to be fixed to a lower bushing that can slide relative to the lower shaft member. The inner rod is adapted to slide within the middle bushing as the length of the shaft changes. The shaft also includes a fastener or locking mechanism, which secures the lower shaft member within the upper shaft member.
Claims13
An adjustable shaft, comprising:
- an upper shaft member having an elongated bore therein with a fixed upper bushing positioned within an upper end of the elongated bore therein;
- a lower shaft member having an elongated bore therein with a middle bushing fixed within an upper end of the elongated bore therein, the middle bushing having an elongated bore extending through the middle bushing;
- a helical inner rod having a lower bushing fixed to a lower end thereof, the bore of the middle bushing having a helical shape to accommodate the inner rod therethrough and to move the middle bushing relative to the upper bushing upon rotating the helical inner rod within the middle bushing;
- and
- a locking mechanism adapted to prevent the helical inner rod from rotating within the middle bushing, to thereby fix a total length of the shaft.
