Claim:
Device for covering facades or walls with vegetation, comprising: a support structure attached to the front of the facade or wall; and at least two modules with a flat structure, square or rectangular, containing a cultivation substrate and having on one of its major surfaces visible vegetation elements, these modules ( 4 ) being mounted in a stationary manner on the support structure ( 7 , 19 ), said support structure comprising of at least two vertical rails ( 7 ), spaced apart from one another, on which the modules ( 4 ) are mounted in vertical rows by being located at a distance from the facade or wall ( 2 ), and by being individually removable, each module ( 4 ) coming in the form of a generally flat vat ( 8 ), with the shape of a parallelepiped, with small thickness relative to its lateral dimensions and with a bottom wall ( 9 ) and lateral walls ( 10 , 10 ′, 11 . 11 ′), and the open surface of the vat ( 8 ) that is opposite to the bottom wall ( 9 ) being closed by an openwork wall ( 12 ) allowing the passage of vegetation elements ( 6 ), the openwork wall ( 12 ) being suitable for holding the substrate ( 5 ) but allowing the plants ( 6 ) to pass, wherein the opposing lateral walls ( 10 and 10 ′), oriented vertically after installation, of each vat ( 8 ), are provided with hanging elements ( 13 ) designed to interact with suitable receiving sites ( 14 ) that are present on the mounting rails ( 7 ), said modules ( 4 ) being mounted by hanging between two parallel rails ( 7 ), wherein the vat ( 8 ) has at least one separating rib or wall ( 9 ′) formed with or attached to the bottom wall ( 9 ), thus subdividing the internal volume of the vat into plural compartments in the horizontal direction, and wherein the upper ( 11 ) and lower ( 11 ′) opposite lateral walls of the vat ( 8 ), oriented horizontally after installation of the modules ( 4 ), have a concave shape and a convex shape, viewed from outside, in profile or cross-section respectively, these shapes being rounded or angular and these walls ( 11 and 11 ′) and the separating rib or wall ( 9 ′) comprising perforations ( 21 ) for the passage of liquid.
