  • Patent number: 4568117
    Abstract: A storage turntable is comprised of a prism having spaced apart polygonal ends connected by a plurality of rectangular sides. Each of the sides provides a desired storage accessory such as a beverage container receptacle or a coin storage device. One side of the turntable is a plain planar surface which merely closes the opening. The console has a rectangular opening and the turntable is rotatably mounted within the opening by axles which extend from the polygonal ends of the prism and are rotatably journaled in bearing blocks attached to the console housing so that rotary movement of the prism sequentially registers a desired one of the storage accessories with the console opening for access by the vehicle occupant. A round thumb wheel is attached to the prism and extends above the surface of the console to provide a convenient means by which the turntable can be rotated. A detent is provided to retain the turntable at the selected position.
