Knockdown-elements framework for supporting and stretching light signs made from transparent or semitransparent flexible materials, constituted by a plurality of vertical bars (1) fixed to a wall, a cantilever roof or the like, by upper (5) and lower (5a) anchoring flanges inclined at 45 DEG , provided at their ends with an upper stretching section bar (14) and a lower stretching section bar (14a), by a plurality of upper (21), intermediate (22) and lower (20) reflective plates, the latter being designed to horizontally slide within a continuous grooved seat (18a), placed on said lower anchoring flanges and vertically on a folded strip (23) provided at the base of the intermediate reflective plates, the lower stretching section bar (14a) being shiftable, integrally with the lower anchoring flanges (5a), upwards and/or downwards, in order to allow a perfect stretching of the flexible sheet (24) which constitutes the display. <IMAGE> |
