Abstract
A multi-step control apparatus is provided for raising and lowering a patient treatment table in response to predetermined successive motions of the foot of an operator. An operating rod mounted transversely of the table has a foot pedal on each end thereof and is biased to a mid position both longitudinally and rotationally. In response to inward pressure on either foot pedal a timing cycle is initiated during which the doctor may then initiate a raising or lowering cycle for the table by stepping on one side or the other of the foot pedal and rotating the operating rod out of a neutral rotational position. However, a raising or lowering cycle cannot be initiated without first moving the operating rod inwardly to initiate the timing cycle so that accidental or inadvertent raising or lowering of the table by simply rotating the foot pedal is prevented.
