Abstract
The invention is for a handle assembly for an adjustable crutch having two upper tubes each of which slides inside one of two lower tubes to adjust the height of the crutch. The handle assembly has a body, a lever attached to the outside of the body; and two locking pins positioned inside the body. Each locking pin is mechanically coupled to the lever and each locking pin is normally biased through tube holes formed in the upper tubes and through tube openings defined in the lower tubes to prevent the sliding of the upper tubes inside the lower tubes. The depression of the lever causes the locking pins to retract from the tube holes and the tube openings such that a user may slide the upper tube inside the lower tube to change the crutch height.
