ABSTRACT:
An exhibition screen arrangement is formed by a plurality of mutually joined rightangular frames, foldable in two directions relative each other, which are arranged in two sets (1,2), one end frame in each set being foldably connected to each other about a hinge (4). The side frame members (101,201) in both sets (1,2) are each formed by two parallel, spaced section elements (30), with an undercut projection (31). The elements (30) are mutually alike and are oriented in each such side member for mutually forming one half of a dovetail joint. The projections (31) are formed with cuneiform surfaces so that the dovetail joint is established by snap-lock action, the sections (30) deflecting out in a direction normal to the plane of the frame. The turned-over portions (33) of the projections are tapered towards the end of the respective element (30) so that the edge section of the turned-over portion (33) of the element projection is substantially adjusted to the deflection curve of the element.
