Abstract
An adjustable length shaft assembly including a handle portion and an extensible shaft. An upper end of the shaft includes a set of locking teeth. The handle has an internal locking mechanism with a tooth rack to accommodate the locking teeth. A control handle is rotated in a first direction, rotating the teeth away from the tooth rack, where the teeth are in a disengaged, unlocked position. With the teeth unlocked, the shaft can be longitudinally adjusted to achieve the desired length. Then, the control handle is rotated in a second direction, rotating the teeth into the tooth rack, where the teeth are in an engaged, locked position. In this manner, the teeth and the tooth rack provide a plurality of positive locking positions, each position providing a different shaft length.
