A portable computer tray assembly (20) which includes a relatively thin, structurally rigid and length adjustable support surface (27) to accommodate and support a variety of portable computers (33) thereatop. The computer tray assembly (20) includes a relatively thin platform member (21) having a plurality of shallow strengthening ribs (23) laterally spaced-apart thereacross. Further, a relatively thin support member (24) is positioned adjacent and in abutting contact with the platform member (21), and includes a plurality of shallow support ribs (26) laterally spaced-apart across the support member. These support ribs (26) are formed for sliding interengagement with the strengthening ribs (23) of the platform member (21) to provide sliding interengagement therebetween to lengthen the support surface (23) which is aggregately formed by the platform member (21) and the support member (24). The interengagement between the ribs (23, 26) further substantially prevents lateral motion of the support member (24) relative the platform member (21). The support surface (27) further includes an upstanding first lip (30) and an opposite upstanding second lip (31) to retain a portable computer (33) therebetween.

An adjustable length portable computer tray assembly comprising: a relatively thin platform member having a contacting surface and defining a plurality of relatively shallow, parallel, strengthening ribs which are laterally spaced-apart across said platform member and extending longitudinally therealong; a relatively thin support member having a top sliding surface and a bottom sliding surface each defining a plurality of relatively shallow, parallel, support ribs which are laterally spaced-apart across said support member, said support ribs of said bottom sliding surface being formed for sliding interengagement with said strengthening ribs of said platform member in a manner substantially preventing lateral motion of said support member laterally along said platform member while providing longitudinal sliding support for selectively positioning between a retracted position and an extended position; a relatively thin engaging member having an engaging surface defining a plurality of relatively shallow, parallel, engaging ribs which are laterally spaced-apart across said engaging member, said engaging ribs of said bottom sliding surface being formed for sliding interengagement with said support ribs of top sliding surface in a manner substantially preventing lateral motion of said engaging member laterally along said support member while providing longitudinal sliding support for selectively positioning between a retracted position and an extended position, said support member and said engaging member aggregately cooperating to provide a substantially flat, length adjustable support surface; and an upstanding first lip and an opposite upstanding second lip each extending upwardly from said support surface, and each extending longitudinally along one of said platform member, said support member and said engaging member, on opposed sides of said support surface.
