ABSTRACT:
A housing adapted to be mounted beneath the top of a table and a shelf sized to fit substantially within the housing are operatively connected by a pair of telescoping rails which guide movement of the shelf between a retracted position in which the shelf is substantially within the housing and an extended position in which the shelf has a substantial portion thereof outside the housing. The rails pivot about an axis to change the height of the shelf with respect to the top of the table and the entire assembly includes a mechanism for securing the shelf in the extended position. The housing includes a vertically stepped slot in which a pin secured to the rails is movable to hold the shelf at predetermined heights with respect to the top of the table corresponding to the steps of the vertically stepped slot.
