  • Food processor with a transmission device
    Patent number: 7306362
    Abstract: A food processor includes a drive unit, a food processing tool driven rotatably by the drive unit, a rotary support, and a transmission device. The transmission device includes a first transmission unit driven rotatably by the drive unit and defining a first drive axis, a second transmission unit driving rotation of the rotary support and defining a second drive axis, and a coupling member that couples the first transmission unit to the second transmission unit. The coupling member permits movement of the first transmission unit relative to the second transmission unit from a first position, where the first drive axis is aligned with the second drive axis, to a second position, where the first drive axis forms an angle with the second drive axis. The coupling member enables transmission of drive power from the drive unit to the rotary support when the first transmission unit is at the first position.
