摘要： 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.

摘要： A child carrier includes a carrying harness having a waist strap, a child supporting part connected with the carrying harness and including a hip support portion and a torso support portion connected with each other, and an expandable part extending across the hip support portion and operable to adjust a bottom distance between the torso support portion and the carrying harness. The expandable part has a first end anchored to the waist strap or the child supporting part in a region adjacent the waist strap, and a second end anchored to the child supporting part at a location distant from the first end. The expandable part is foldable to displace the first end and the second end toward each other for reducing the bottom distance, and is stretched as the first and second ends are displaced away from each other for increasing the bottom distance.

摘要： A child safety seat includes a seat shell having two sidewalls respectively provided at a left and a right side for restricting sideways movement of a child on the seat shell, a buffering part movably connected with the seat shell, a retaining mechanism and a release mechanism. The buffering part is movable between a first position corresponding to a stowed state where the buffering part is retracted toward one of the sidewalls, and a second position corresponding to a deployed state where the buffering part protrudes sideways from the sidewall. The retaining mechanism is operable to hold the buffering part in the first position. The release mechanism includes an operating device that is disposed adjacent to a thigh region of the seat shell and is operatively connected with the retaining mechanism, the operating device being operable to release the buffering part from the hold of the retaining mechanism.
