base plate adapters 80 shaped as shown in fig1 having a tongue 81 which snaps into either of the base place sockets 14 and a panel retaining lip 82 along its upper edge attached to the ceiling by nails or screws are extruded panel ceiling retainers 83 shaped as shown in fig1 having a panel retaining slot 84 flexible panels 85 are snapped into place between the base plate adapters 80 and the panel ceiling retainers 83 being retained by the lips 82 and the slots 84 the panels 85 can be of any available sheet material opaque translucent even transparent and of various colors or textures if translucent lighting can be installed behind them thus creating with little effort an almost unlimited number of possibilities for the designer since the panels 85 are flexed bending forces are imposed upon the legs 11 and 15 of the base plates 10 these forces are resisted by molded triangular braces 86 having short transverse tongues 87 which snap into the base plate connector slots 18 as indicated in fig1 the curved panels 85 are connected end to end by extruded cove ceiling partition strips 90 having a rear spline 91 against which the ends of the panels 85 abut the front faces of the strips 90 are cut back at each end and the exposed ends of the splines 91 snapped behind the base plate.
