  • Patent number: 4372631
    Abstract: A lightweight drafting table having a full-size drafting board of sandwich-type construction, the underside of which is glued to a yoke having three support arms which are disposed approximately parallel to each other and which are connected to a cross member to form a rigid structure for supporting two drawers. The board provides the cover for the drawers when they are closed. Each drawer has a slot formed in each of two sides thereof; the walls of each slot ride on a key which protrudes laterally from one of the support arms. A slight drag between the key and the slot prevents each drawer from opening under the force of gravity alone when the drafting board and the drawer are tilted at an angle of several degrees to the horizontal and the drawer is fully loaded. The yoke is pinned to a pair of vertical support members attached to a four-legged base and to a pair of braces, each of which is also bolted to one of the support members to form a lightweight structure of exceptional strength.
