Abstract
Abstract An improved panel wall system is disclosed with means for interconnecting the panels in any desired angular relationship while providing a sight barrier through the joint. As many of the panels may be connected as are desired; and they may be placed in any desired configuration. Each panel includes an insert assembly to provide its exterior face; and these may be removed and changed, if desired. A full line of shelving and cabinets may be assembled to the panels with a limited number of interchangeable components. The cabinets include a flipper door which will not rack when opened or closed, and which slides beneath the top of the cabinet in the open position, yet has its edges flush with the top and bottom of the cabinet in the closed position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
244 words
In a panel wall system, an improved panel connection for first and second panels, each panel including a frame, said connection comprising: first and second connector elements extending the length of each panel and connected to an associated vertical frame member, said connector elements each including a first curved longitudinal edge having an inner concave surface and a second curved longitudinal edge having an outer convex surface conforming to the inner concave surface of said first edge, and said connector elements being placed on adjacent panels in inverted relation, whereby the concave edge surface of one connector element on said first panel encompasses the convex edge surface of another connector element on said second panel defining a first pivot connection, and the convex edge surface of said one connector element is encompassed by the concave edge surface of said another connector element defining a second pivot connection, when said panels are placed in side-by-side parallel arrangement, but permitting one panel to be pivoted relative to the other panel about said first pivot connection away from said side-by-side arrangement in one direction, and to be pivoted relative to the other panel about said second pivot connection away from said side-by-side arrangement in the opposite direction while maintaining connection between the convex curved edge surface and the concave curved edge surface of the one of said pivot connections about which said panel is pivoted to thereby provide a light seal in the joint between said panels.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
The apparatus of claim 1 further comprising preformed bracket means attached to the frames of both of said panels in the adjusted position for holding said panels at said adjusted position.
Claim 4
Dependent Claim
55 words
The apparatus of claim 2 further comprising a connector plate at each end of each upright vertical frame element, the connector plate at the upper end of the frame element being used for attachment to said connector brackets, and the connector plate at the lower end of the frame element being used to receive levelers.
