US Patent 7665475 Utility shelf for a dishwasher dish rack

A utility shelf includes a retaining frame pivotally connected to a support frame. The support frame is pivotally connected to a side portion of a dish rack through a plurality of hinge elements. Similarly, the retaining frame is pivotally connected to the support frame through a corresponding plurality of hinge members. The hinge members on the retaining frame are adapted to abut a stop member that positions the retaining frame at an angle relative to the support frame. With this arrangement, the retaining frame can be extended from the support frame to support objects during a washing operation.
