Adjustable shelf for microwave ovens

Apparatus for use in a microwave oven cavity, comprising a rotatively driven turntable platform positioned near the floor of the oven cavity, a horizontally extending shelf member positioned above the platform, and a plurality of supporting legs depending from the shelf member and being selectively movable between a first position in which the legs rest upon the turntable platform and a second position in which the legs straddle the platform and rest upon the floor of the oven cavity, said shelf member rotating with the platform when the legs are in the first position and remaining stationary when the legs are in the second position.

A shelf for use in a microwave oven cavity, comprising a horizontally extending platform, a plurality of legs which depend from the platform and rest on a supporting surface in the oven cavity, each of said legs having a longer section and a shorter section generally perpendicular to each other and a foot at the junction of the two sections, means including a pivot head at the ree end of each of the shorter leg sections for pivotally mounting the legs to the platform for movement between a first position in which the free ends of the longer leg sections rest upon the supporting surface and a second position in which the feet at the junctions of the leg sections rest upon the supporting surface, the shorter leg sections extending outwardly from the pivot heads and engaging the underside of the platform when the legs are in the first position, the longer leg sections extending inwardly and upwardly from the feet when the legs are in the second position with the free ends of the longer leg sections engaging the underside of the platform, and detent means for holding the legs in the first and second positions, said detent means comprising a resilient detent arm carried by the platform and a pair of detent sockets formed in each of the pivot heads for engagement by the detent arm when the legs are in the first and second positions.
