FIG. 1 is a front top perspective view of the invertible table unit of my
invention, showing a pair of auxiliary folding tables installed in their
storage positions in the main table.
FIG. 2 is a front perspective view of the invertible table unit of FIG. 1,
with one auxiliary folding table shown exploded from the main table and
the other shown removed and unfolded for use.
