Abstract

An adjustable support for a portable computer or the like having a main or center board, side boards, and cylindrical stackers interconnecting them. The device is designed to hold a portable computer on the main board and to dispose it weightlessly in the lap area of a seated user by means of the side boards resting on the arms of the easy chair, or couch or sofa on which the user is seated. The distance between the side boards and the main board of the device may be varied by changing the number of stackers each of which have mating male and female ends to enable interconnecting them. The main board and the sideboards may have through-holes of two different diameters each: a larger one for receiving and rendering flush the head of a nut or bolt cooperating with a respective stacker end to secure the stacker rigidly to the board; a smaller one for snugly receiving reduced portion of the nut or bolt. The larger diameter portions of the through-holes only penetrate halfway through the boards. The female ends of the stackers are threaded openings which will receive the threaded bosses constituting the male ends of other stackers for interconnection end to end or the threaded ends of bolts to secure the stackers to boards. The nuts beyond their heads are each formed with a sleeve snugly received in the reduced diameter of through-holes and mating with threaded boss on the end of a stacker.
