The plates allowing passage to light into the wearhouse are glued to the rods, under supports and ridges. The light frame is hinged around a profile (17) which is formed on a support (18) formed as a rectangular casing. A ridge (3) has the shape of an inverted "U", on the upper side of which are two flanges facing downwards at a preferred angle of 22.5 degrees to the horizontal. The inside of the downwardly facing constituents of the U-shaped part is formed with small ridges which function as internal screw threads. A vertical bolt acts as fixture for the rods-ridge-rods coupling (9). |
