摘要：A shelf assembly having an infinitely vertically adjustable top surface is providedfor supporting electronic circuit boards in a storage cabinet. The shelf assembly includesa shelf base having a bottom support surface and a front and rear wall wherein the frontwall defines at least one horizontallly extending elongate slot therein. A verticaladjustment tray is positioned on the support surface of the shelf base and includes afront wall and rear wall which each define at least one elongate slot therein whichextends generally laterally upwardly. Vertical adjustment knob elements are secured tothe front wall of the vertical adjustment tray and extend through the elongate slot in thefront wall of the shelf base so that lateral movement of the knob member will laterallytranslate the vertical adjustment tray relative to the shelf base. A shelf top is positionedon the vertical adjustment tray and movably secured relative to the shelf base so as toprevent lateral movement thereof while allowing vertical movement relative to the shelfbase. The shelf top also has front and rear walls with slot engagement pegs extendinginwardly therefrom and into operative engagement with at least one upwardly extendingslot in each of the front and rear walls of the vertical adjustment tray whereby lateralmovement of the knob elements of the shelf assembly causes the vertical adjustment

tray to laterally translate relative to the shelf base and the shelf top to be verticallyactuated by the lateral movement thereof.
