Wheeled carrying apparatus

A wheeled carrying apparatus comprising:

• a frame structure including a standing frame and a handle frame that is coupled to the standing frame via a bar linkage, the standing frame including a leg frame;
• a first wheel mount carrying a first wheel and pivotally connected with the standing frame, the first wheel being rotatable relative to the first wheel mount about a first wheel axis;
• a locking assembly including a first wheel mount latch movably connected with the standing frame, the first wheel mount latch being adapted to be engaged with the first wheel mount to rotationally lock the first wheel mount with respect to the standing frame, and adapted to be disengaged from the first wheel mount to unlock the first wheel mount so that the first wheel mount is rotatable relative to the standing frame for changing an orientation of the first wheel axis;
• an actuating assembly coupled to the first wheel mount latch, wherein the actuating assembly includes a link actuator, the link actuator being movably connected with the bar linkage;
• and
• a release mechanism including an operating part provided on the leg frame at a location distant from the first wheel mount latch, the release mechanism being operable to cause the actuating assembly to actuate the first wheel mount latch so that the first wheel mount latch disengages from the first wheel mount.

• an actuating assembly coupled to the first wheel mount latch, wherein the actuating assembly includes a link actuator and wherein the link actuator is slidably assembled with the frame structure;
• and
• a release mechanism including an operating part provided on the leg frame at a location distant from the first wheel mount latch, the release mechanism being operable to cause the actuating assembly to actuate the first wheel mount latch so that the first wheel mount latch disengages from the first wheel mount, wherein the operating part has a ramp surface, the release mechanism being operable to cause the first wheel mount latch to unlock the first wheel mount via a sliding contact between the ramp surface and the link actuator.
