inge-type articulated coupling element composed of the single loop section (4.1) and double loop section (5.2). The two parallel parts 6,8 of the section 1 and 10 of the section 2 bear the apertures 7,9,18 wherethrough the screws 17 pass to connectthe beams 11 and 12 having flattened ends and respective apertures. The sections 1,2 of the coupling element are interconnected via the cylindrical axle 13 passing through the circular configurations 3 of the loops 4,5. The loop 4 of the section 1 of the coupling element engages in the void space of the loops 5 of the section 2. The panels 14 and 15 are connected to an arrangement of coupling elements the use of which is modified by needs (e.g. use in exhibitions for the suspension of bills, warnings etc). The invented coupling element is applicable to lots of embodiments. |
