Golf club shaft
First Claim
1. An adjustable length golf club comprising:
- an engaging mechanism;
a rotational shaft connected with the engaging mechanism and being configured to rotate upon movement by the engaging mechanism;
a locking mechanism connected with the rotational shaft, the locking mechanism including a locking insert and a locking collar located on the locking insert, the locking insert being configured to retain the locking collar during axial movement; and
a lower shaft having an inner surface that is in frictional contact with the locking collar, wherein the locking insert is threadingly engaged with the locking collar and a first rotational movement in a first rotational direction by the rotational shaft causes the locking insert to move the locking collar creating a frictional locking engagement between the locking collar and the inner surface of the lower shaft, wherein the locking collar has at least two finger portions that engage an engaging surface of the locking insert to prevent movement with respect to the lower shaft.

Abstract
An adjustable length golf club including an engaging mechanism, a rotational shaft, a locking mechanism, and a lower shaft. The rotational shaft is connected with the engaging mechanism and is configured to rotate upon movement by the engaging mechanism. The locking mechanism is connected with the rotational shaft and includes a locking insert and a locking collar located on the locking insert. The locking insert being is configured to retain the locking collar during axial movement. The lower shaft has an inner surface that is in frictional contact with the locking collar. The locking insert is threadingly engaged with the locking collar and a first rotational movement in a first rotational direction by the rotational shaft causes the locking insert to move the locking collar creating a frictional locking engagement between the locking collar and the inner surface of the lower shaft.
