Abstract

A wheeled carrying apparatus includes a handle frame rotatable relative to a standing frame between a first and a second position, a wheel mount pivotally connected with the standing frame, a wheel mount latch adapted to engage and lock the wheel mount with respect to the standing frame and to disengage and unlock the wheel mount so that it is rotatable for changing orientation of a wheel axis, a link actuator coupled to the wheel mount latch via a linking part that is movable as the handle frame rotates for causing the wheel mount latch to engage or disengage the wheel mount, and a release mechanism including a cable assembly that couples an operating part carried with the handle frame to the wheel mount latch, the operating part being operable to cause the wheel mount latch to disengage the wheel mount in the first position of the handle frame.
