Abstract
A mechanically-driven, low-profile, portable turntable for use in cooking ovens, especially microwave ovens, for rotating food stuffs while cooking. All moving parts, except the power spring used to drive the turntable are formed from low loss plastic and the spring is contained in a microwave reflective case to preclude overheating thereof. The low profile is achieved by providing a unique drive mechanism for the turntable in which the power spring driven gear is made to partially surround and envelop the spring case. Further, the gear train cooperating with the main power spring driven gear and with a speed-controlling governor is effectively 'wrapped' about the spring case in a concentric fashion with the individual gears in the gear train being vertically overlapped.
