ABSTRACT:
The louver system disclosed is of a basic type with adjustable-angle slats arranged between two uprights (1) provided with holes in which swivel mounts (3) are located for the receipt of clips (5) to which the slats (4) are fitted. The single clip (5) is embodied in two half-sections (52, 51) the mating surfaces of which incorporate a dovetailed key (6) and a matching groove (7) respectively; the two half-sections are thus able to slide relative to one another into a locked position determined by a projecting longitudinal lip (18) which, in addition to acting as a stop, prevents infiltration of water between the two half-sections, and are retained by a releasable catch mechanism (8, 9); in a preferred embodiment, one half-section (51) of each clip (5) has a flexible quadrangular element (12) designed to snap into a corresponding quadrangular socket (10) offered by the swivel mount (3).
