deployed position in which the upper balance plate piece 40 is vertically aligned with the lower balance plate piece 41 as shown in fig3 b after the upper balance plate piece 40 rotates to the vertical deployed position so that the upper balance plate piece 40 is vertically aligned with the lower balance plate piece 41 a balance plate guide track 68 guides the downward vertical movement of balance plate pieces 40 and 41 as gravity pulls balance plate pieces 40 and 41 toward the floor as shown in fig3 c after the balance plate guide track 68 guides the downward vertical movement of balance plate pieces 40 and 41 toward the floor the lower balance plate piece 41 rests on the floor the preferred embodiment includes at least one balance plate foot 56 preferably this balance plate foot 56 is adjustable due to an adjustable balance plate foot 56 it is unnecessary to have wheels which can easily damage floors and which cannot be adjusted to provide a level table surface on an unlevel floor the preferred embodiment includes at least one finger grip located on the part of the upper balance plate piece 40 which faces the interior box the lower balance plate piece 41 contains at least one balance plate stop 67 to stop the vertical upward motion of balance plate pieces 40 and 41 at the proper height when the upper balance plate piece 40 is pulled in a vertical upward motion to return the upper balance plate piece 40 to a storage position as shown.
