Abstract: An improved desk includes a top supported by opposite end assemblies and in turn supporting a juxtaposed end of an extension top having an end assembly at its opposite free end. The juxtaposed end of the extension top is attached to the desk top by a mounting assembly allowing of both vertical as well as horizontal displacement of the extension thereabout. The desk and extension end assemblies each are provided with a lowermost vertically adjustable leg unit permitting selective, independent variation of the height of the desk and extension tops both with respect to the underlying floor and with respect to one another. Manipulation of the leg unit adjustment is facilitated by the inclusion of a snap-out panel manually removable from each end assembly.

Abstract: A file arrangement includes a cabinet housing, a plurality of vertically stacked file elements with an interlock assembly carried by one cabinet lateral wall precluding the opening of more than one element at a time as the first opened drawer vertically displaces a roller on the assembly to block any displacement of similar rollers adjacent the remaining file elements. A separate lock bar assembly adjacent the opposite cabinet lateral wall includes a plurality of lock dogs engageable with the front of the file elements and vertically shiftable upon actuation of a lock mechanism. Operation of the lock mechanism and its associated lock bar assembly also actuates a transfer rod joining both assemblies to simultaneously and equally displace the interlock assembly and a plurality of lock dogs thereon to lock both sides of all file elements within the cabinet.

Abstract: An article of furniture includes a frame to which is attached a removable panel having fixed fastening means adjacent its top and bottom edge. The bottom-most fastener means are pivotally engageable with fixed brackets on the frame while the top-most fastener means are insertable through the frame and subsequently locked in an assembled position by means of a reciprocal latch member operable only from within the confines of the furniture article.
