Abstract: A shaped-section slat device comprising a shaped-section slat (1) having a visible face (10A) and two longitudinal edges having male and female assembly means (18, 20). The male assembly means (18) are connected to the visible face (10A) via an intermediate zone having a plane visible margin (22) set back relative to said visible face (10A), said male assembly means themselves being set back relative to said visible margin (22). Each of the longitudinal edges of the slat is provided with a groove in which an assembly strip can be inserted so that it projects from said groove over a width greater than the depth of the other groove.

Abstract: The assembling element according to the invention is intended to be laid on a supporting surface with other, similar elements, in the manner of tiling. The element comprises a decorative assembling plate which is made in one piece and of which the edges form male and female sides for assembling. The male side comprises a connection strip which is intended to be disposed against the supporting surface and which is joined to its exposed face by a projection of the male side. This strip presents a boss parallel to the edge of the plate. A female side presents a free end which is joined to its exposed face by a projection of the female side. A space for connection, adapted to contain the boss of a male side of an adjacent element, is hollowed beneath the plate.

Abstract: A finishing device or “molding” comprises at least one support strip designed to be fixed on a support structure, a visible strip, and at least one spacer flank holding the visible strip at a distance from the support strip. The spacer flank is connected to the visible strip by a link strip which extends parallel to the first side portion with which it forms a first fold. The free margin of the second side portion is fitted with a closure element comprising a closure strip which forms a second fold together with said second side portion. The visible strip of the molding is made of extruded transparent plastics material, and the device is suitable for containing a decorative insert in the form of a strip suitable for being placed against the inside face of the visible strip and of being held in place by the two above-mentioned folds.
