ABSTRACT:
An adjustable table is described having three support structures arranged symmetrically around the perimeter of the table. Each support structure is supported on a base by means of a two dimensional joint, such as a leaf spring, having an axis of rotation tangential to a circle centered at a central point of the table. Each support structure supports the table by means of a three dimensional joint such as a ball in socket joint. Each support structure includes a threaded spindle and a rotatable threaded bolt for adjusting the separation between the table and the base.
