US Patent 7694387 Retractable handle assembly

A retractable handle assembly includes a shank, an extension pipe, a retractable pipe, a receiving member, an expandable member, a control member, a driving member, and a rotation member. The retractable pipe is movable relative to the extension pipe by rotation of the rotation member to adjust the distance between the retractable pipe and the extension pipe so as to adjust the length of the retractable handle assembly. Thus, when each of the push flanges of the control member is inserted into the respective locking recess of the expandable member by rotation of the control member, the control member is locked by the expandable member, thereby preventing the control member from being jammed due to an excessive rotation.
