Abstract: A cabinet includes a first shelf disposed inside the cabinet at a height above waist level, the first shelf having a first retracted position and a first deployed position below and outwardly from the first retracted position; a first parallelogram linkage pivotably operably attached to a first end of the first shelf and the cabinet; a second parallelogram linkage pivotally operably attached to the cabinet and a second end of the first shelf; a first shaft having a first end operably engaged with the first parallelogram linkage, the first shaft having a second end operably engaged with the second parallelogram linkage; and a drive motor operably engaged with the first shaft to operate the first and second parallelogram linkages outwardly and downwardly to position the first shelf from the first retracted position to the first deployed position.

Abstract: A cabinet includes a first shelf disposed inside the cabinet at a height above waist level, the first shelf having a retracted position and a deployed position below and outwardly from the retracted position. First and second pivot arms are pivotally operably attached to the first end the first shelf and to the cabinet, the first and second pivot arms forming a first parallelogram. Third and fourth pivot arms are pivotally operably attached a second end of the first shelf and to the cabinet below the first shelf, the third and fourth pivot arms forming a second parallelogram. A first drive motor operably is operably to one of the first and second pivot arms and the third and fourth pivot arms to swing the first and the second parallelograms outwardly and downwardly from the cabinet to position the first shelf from the retracted position to the deployed position.
