In accordance with the present invention, there is provided a workstation
or other heavy object which is easily moved, yet steady and stable when
parked. Underneath this object is attached a multiple air-bearing device
having a backplate, a membrane which is selectively bonded to the
backplate, and a stencil and dimple which further prevent separation of
the membrane from the backplate and which also provide a bearing surface
for the workstation to rest with stability against the floor. Pressurized
air is introduced through the base and behind the unbonded portions of
the membrane, inflating the membrane and creating lift, and additionally
forming a pneumatic seal against the floor. Air passages through the
membrane and within the sealed footprint allow air to flow into and
through the region between the membrane and the floor, creating an
air-lubricated bearing that allows nearly frictionless motion of the
heavy object.
