Adjustable length and torque resistant golf shaft
View Patent ↗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, and an upper end dimensioned to be fixed to the upper bushing. The inner rod is adapted to slide within the middle bushing as the length of the shaft changes.
1. An adjustable golf shaft comprising:
an upper shaft member having an elongated bore therein with an upper bushing fixed 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 upper end of the lower shaft member having a flared end, and wherein the flared end is configured to fit within an inner surface of the upper shaft member; and
an inner rod having a lower bushings fixed to a lower end thereof, an upper end of the inner rod is fixed to the upper bushing, and the inner rod is adapted to slide within the middle bushing.
2. The shaft of claim 1 , wherein a distance between the middle bushing and the upper bushing changes as the length of the shaft increases or decreases.
3. The shaft of claim 1 , further comprising a putter head, wherein the putter head is attachable to a lower end of the lower shaft member.
4. The shaft of claim 1 , further comprising a grip, the grip attached to an outer surface of the upper shaft member.
5. The shaft of claim 1 , wherein the lower shaft member has a lower portion and an upper portion, the upper portion having a stepped portion, wherein the stepped portion results in the upper end of the lower shaft member having a greater outer diameter than an outer diameter of the lower end of the lower shaft member.
6. The shaft of claim 1 , wherein the middle bushing has an elongated bore extending through the middle bushing, and wherein the bore is dimensioned to prevent the inner rod from rotating within the bore forming a torque resistant shaft.
