<p>CONVERTIBLE CABINET SUPPORT The present invention relates to a retractable undercarriage formed preferably by three supporting members, two of which are leg members and the third a wheel, member. The support members are moved to either move the leg members into supporting position and retract the wheel member, or to move the leg members into the retracted position and the wheel member to the supporting position. When the leg members are in the retracted position and the wheel member in supporting position the end of the cabinet that would otherwise be supported by the foot members rest on further wheels so that the cabinet is completely supported on wheels and may be moved relatively freely about the floor.</p> |
