ABSTRACT:
A table suspended from a room ceiling has a table top that is positionable between a retracted first position against the ceiling and a second position extended from the ceiling toward the floor. Extension and retraction occur through a pivotal arm assembly. The arm assembly is controlled by electric or manual powered drive mechanisms. The drive mechanisms are enclosed in a modular housing that is manufactured to interchangeably accept either the electrical or the manual drive mechanisms. The suspended table includes a table top that is rotatable about a vertical axis.
