Abstract
Abstract A corner work center includes a mounting unit for a computer and like equipment which quickly attaches to two adjoining surfaces at the same height. The unit eliminates the need for an expensive and complex intermediate or third top and the requisite hardware. The unit includes an elevated plate mounted on the frame and a forward tray or bridging surface which is captured by the frame and extends forwardly of the frame at a lower elevation and bridges the included angle between the adjoining surfaces. The unit may also include an articulating arm assembly having a positionable keyboard tray which may be positioned beneath and forwardly of the forward tray. With the arm assembly the keyboard tray can be extended for use or retracted when not in use. The tray includes handles and adjustable bumpers. The unit also includes one or more swing arm supports secured to the frame to position computer components or accessories at desired locations for effective use. The swing arm supports include trays and swivel assemblies supporting the trays which allow the trays to be rotated and angularly adjusted relative to the frame of the unit.
