Abstract

Abstract A rack is supported within the wash chamber of a dishwashing machine by a connecting means permitting selective manual adjustment of the vertical level of the rack side. The connecting means includes a slidable surface portion inclined to serve as a ramp and bear on a support member whereby movement of the ramp against the support member causes vertical movement of the rack side. Manual control means on the rack is linked to the connecting means such that manipulation of the control means is translated to the slidable surface portion whereby the vertical positioning of the rack side is selectively adjusted.
