Patent ID: 8672336

Claim:
A wheeled vehicle with at least one front wheel and one rear wheel, a collapsible upright handle assembly, a supporting unit pivotable between a first position and a second position, and a latch mechanism for securing the supporting unit in either the first position or second position, comprising: a handle secured to the latch mechanism, whereby rotation of said handle changes the latch mechanism from a latched state to an unlatched state; a longitudinal member attached at a proximal end to said handle, wherein said longitudinal member extends in a direction generally parallel to the upright handle assembly; an angled member attached to the distal end of said longitudinal member; whereby said collapsible upright handle assembly is comprised of first and second column members, wherein said first column member is slidable within said second column member; a longitudinal aperture located on a wall of said second column member; a rigid protuberance in connection with said first column member, whereby said protuberance extends away from said first column member and through said aperture on said second column member; whereby said protuberance is configured to contact said angled member as said first column member is slid within said second column member, and said contact causes movement in said angled member so as to rotate said handle.
