  • Patent number: 7464956
    Abstract: A foldable frame assembly includes first and second frames pivotally connected to each other and respectively having a wheel-carrying end and a foot end. The tabletop bracing member is pivotally connected to the first frame in proximity of a handgrip portion, and supports a machine thereon such that in a propped up position, the center of gravity of the machine is disposed rearwards from the table top bracing member. The tabletop bracing member has a retaining region brought to engage a retained region on the second frame. The base prop is disposed to sit on the ground surface in the propped up position so as to relieve the frame subassembly of the mass of the machine, thereby facilitating displacement of the frame assembly to a folded or unfolded position. A locking member is disposed to place engagement of the retaining region with a selected one of the first and second retained regions.

  • Patent number: 7222865
    Abstract: A foldable frame assembly includes a base frame having a wheel-carrying end for mounting a wheel unit, a handgrip end, and an intermediate portion connected to a prop member so as to lift the base frame to a standing position. A tabletop has a front tabletop end pivoted to the intermediate portion for suspending a machine above the ground surface so as to enable a rear tabletop end to turn from a working position to a folded position. A bracing member has an anchoring end pivotally mounted on the wheel-carrying end, and a slidable end coupled with the rear tabletop end such that when the rear tabletop end is turned from the working position to the folded position, the slidable end is turned to be close to the intermediate portion. A rear locking unit is disposed to guard against movement of the slidable end.
