  • Patent number: 6606827
    Abstract: This device has a principal section (1) and an auxiliary section (6) with means of attachment and detachment under pressure. The auxiliary section (6) has guides (61) for fitting an advertising support (7). The section (1) defines two wings (11 and 12), a recess (13) for the lighting means (2) and a seat (14) for a non-slip strip (4) and a row-numberer (5). The wing (12) has a longitudinal channel (17) for fitting lighting means (8) and a transparent protector, forming a hollow portion (9) for running cables (81) through it. The seat (14) has two interior mortised portions (14a and 14b), one of which forms a duct for the power-supply cables (51) of lighting means (52) housed in the orifice (53) of the numberer (5).
