Abstract
A wheeled carrying apparatus includes a standing frame, a handle frame, a wheel mount, a locking assembly and a release mechanism. The handle frame is rotatable between a first and a second position of different inclinations. The wheel mount carries a wheel and is rotatable relative to the standing frame for changing an orientation of the wheel axis. The locking assembly includes a wheel mount latch adapted to engage and rotationally lock the wheel mount relative to the standing frame, and to disengage and unlock the wheel mount. The release mechanism includes an operating part carried with the handle frame and is configured so that the operating part is operable to cause the wheel mount latch to disengage the wheel mount when the handle frame is in the first position, the operating part being operatively decoupled from the wheel mount latch when the handle frame is in the second position.
