Abstract
This invention is a revolving examination table apparatus to be used by, for example, optometrists during eye examination to place a desired instrument between the patient and the doctor. More particularly, the table apparatus includes (1) a main, circular support base assembly; (2) a revolving table top assembly rotatably mounted on the support base assembly; and (3) an electrical control and drive assembly operable to control rotation of the revolving table top assembly. A central portion of the support base assembly and the revolving table top assembly is cut out to receive a chair and person (optometrist) therein while the patient sits opposite therefrom with the table apparatus therebetween. The electrical control and drive assembly operates to (1) rotate the table top assembly to one of seven stations and stop automatically; (2) supply electrical power to each station when in the usage position to an electrical receptacle to power an instrument at that station; (3) control direction of table top assembly rotation; (4) control speed of subject rotation; and (5) provide an override switch to by-pass a station, if so desired.
