Abstract
The specification discloses a rigid furniture assembly and assembly method for providing shelving and the like wherein no fasteners or fastener-receiving openings are visible after assembly. The assembly includes joined panels having abutting joint surfaces lying in three mutually perpendicular planes. At least two parallel panels are secured to a perpendicular third panel, the two panels with the third attached thereto also being joined to parallel, commonly facing surface portions of a fourth panel. The panels are joined using pockets recessed in edges of the panels, which pockets receive slidingly engageable, recessed fastening means including slotted clips and headed, shouldered screws received in the clips. The panels slide together without the necessity of any bending or distortion such that all recessed pockets and fasteners are hidden after assembly.
