Abstract
An improved crank handle assembly for a shade umbrella suitable for patio or beach use, which has a bolt and a crank formed as a unitary member where the head of the bolt is insert molded into the hub of the crank in its manufacture. An annular spacer is mounted on each end of the bolt. An end of the bolt has a reduced threaded portion, which receives a washer and a nut, and the main body of the bolt forms a shoulder adjacent to the threaded portion. The washer abuts against the shoulder and one of the spacers at one end of the bolt. Tightening of the nut causes the washer to bottom out against the shoulder, and the annular spacers to abut against the umbrella pole applying a predetermined amount of compressive force to the crank handle assembly and the umbrella pole.
