At pres ent, for lighting assemblies however show a poor it possible on. ly accomplished for such shapes are of Furthermore L ighting outdoor areas, mo,dular are already known 12úr_at, which flexibility in use, in that they make a limited number of shapes to be the same assemblies, in particular if the- "in-bunches" type.
the structures of the coupling assemblies show a 1 so that positioning the lighting bodies considerable cantilever length relatively to the support pole is not possible, with a further considerable limitation in the configurations which can be obtained in the lighting assemblies.
The purpose of the present invention is to provide a coupling unit for the composition of tubular support structures for lighting assemblies, capable of overcoming the previously mentioned drawbacks.
These purposes are achieved tubular eUement imited mechanical stiffness, w i t h a by a coupling unit for structures comprising at least and at least a tubular element and removably jointed to the characterized in that it -is oupling box-shaped hollow outl the composition of tubular a fixed tubular element, supporting a lighting body., fixed tubular element, provided with at least one c el having two circle-arc-shaped ines opposite to each other, and at least two further box-shaped coupling ement 2.
k elements, each provided with at least one circle-arcshaped hollow outline, with one of the two circle-arcshaped hollow outlines of th.e double- circle-arc-shaped hollow outline coupling element associating with the circle-arc-shaped hollow outline of one of said furtAher coupling element s, concurring to form a first c(amping ring for clamping the same elements against said fixed tubular element, with the other one of said two circlearc-shaped hollow outlines.of the box-shaped coupling element associating with the circle-arc-shaped holldw outline of the other one of said further coupling elements, concurring to form a further clamping ring, for clamping said elements against said tubular element supporting a lighting body.
