ABSTRACT:
A rotatable platform having a relatively circular turntable top rotationally supported above a unitary base by a plurality of wheels which make tangential point contact with the underside of the turntable top. The base includes a raised rim portion that carries the rotationally mounted wheels. A step is formed between the raised rim portion and the remainder of the base that helps prevent food particles from contacting a gear train assembly contained within the base. A flat spiral spring is housed beneath the gear train assembly and cooperates with the gear train assembly to rotate the turntable top. A detent is provided on the base that engages an escapement blade for stopping rotation of the turntable top. The base is substantially square with rounded corners.
