Definitions

  • the present invention relates generally deformed metal structures according to the preamble of claim 1, that is to say the structures which, essentially formed from a single sheet, projecting a mesh network of deformations.
  • the deformations form open mesh delimited by strips inclined on the general plane of the initial sheet, these meshes being obtained by "unfolding" of the latter, that is to say by cutting and stretching of this initial sheet.
  • Expanded metal structures of this type have many uses, and, in particular, they are commonly used, for example in the form of panels, then generally plans, for the constitution of ceilings, of isolation partitions, or fencing, or protective grilles.
  • the present invention generally has for object a provision allowing to draw an aesthetic effect from it different, or additional, to increase it, again, the attractive effect, and thus break a possible monotony of all.
  • a deformed metal structure such as comprising a projecting mesh network of deformations, and characterized in that, a pattern applied to it, this pattern affects only a limited portion of at least some of these deformations, which for at least one group is oriented on the same side for all the deformations of a such group.
  • the pattern is more or less dimmed.
  • a passerby who travels along of a deformed metal structure according to the invention has a changing or fleeting vision of the pattern applied to it, which, successively, appears or disappears, or vice versa.
  • the deformed metal structure concerned is made of expanded metal
  • the present invention therefore also relates to such a production process as defined in claim 5.
  • the deformed metal structure 10 comprises, projecting from this general plane P, on one and the other of the faces thereof, deformations 11.
  • the deformations 11 of the deformed metal structure 10 form perforated meshes 12 delimited by strips 13, which, running over the entire width l of this metal structure deformed 10, while being offset from each other along the length L thereof, are all generally inclined on its general plane P.
  • the strips 13 are generally wavy.
  • the mesh outline 12 is that of a curvilinear triangle isosceles, with concave lateral sides and a convex base.
  • the deformations 11 are formed by the scallops, arched in a chain, formed by the straps 13.
  • these strips 13 each have two sides, both inclined on the general plane P, namely a flank 14, which comes from the surface corresponding to this sheet 10 ', and a side 15, which comes from the thickness of the latter, and the updating of which results from "deployment" to which it was subjected.
  • the flank 14 extends downstream, and the flank 15 upstream.
  • a pattern 16 is applied, on such a face, with the deformed metal structure 10, this pattern 16 affects only a limited portion of at least some its deformations 11, which, for at least one group of these, is oriented on the same side for all the deformations 11 of such a group.
  • motif 16 has been assumed be constituted by a simple letter O, of circular outline, in the embodiment shown.
  • the deformations 11 belong to straps 13 forming between them openwork 12 meshes
  • the pattern 16 affects only one of the sides of these strips 13, in this case their side 14, which, located downstream in the direction of stretching, comes from the corresponding surface of the initial sheet 10 '.
  • FIGS. 6A, 6B, 6C we have substituted, for more clarity, with such scrolling, a gradual inclination of the deformed metal structure 10.
  • the observation is supposed to be made at an angle which, as indicated by arrow A at the Figure 3, is oblique in a first direction relative to the plane general P and mainly concerns the side 15 of the straps 13: for such an angle of observation, the motif 16 is not obviously not apparent.
  • the observation is supposed to be made at an angle which, as indicated by arrow B at the Figure 3, is substantially perpendicular to the general plane P and allows you to see both, but at an angle, the side 15 of strips 13 and their side 14, as in the plan view of the Figure 1: for such an angle of observation, the pattern 16 is apparent, but, due to its fragmentation, on the one hand, and the biased observation that is made of it, on the other hand, it is barely visible.
  • the observation is supposed to be made at an angle which, as indicated by arrow C at the Figure 3, is oblique to the general plane P, in a opposite direction to that corresponding to the viewing angle marked with the previous arrow A, and mainly concerns the flank 14 of the straps 13, being substantially perpendicular to it: for such an angle of observation, the pattern 16 appears in all its fullness, the flanks 14 of strips 13 reconstructing, by projection on a plane perpendicular to this angle of observation, the face corresponding to the initial sheet 10 '.
  • ground 16 is a O with a circular outline
  • the 16 'pattern is a slightly O flattened into an ellipse.
  • applying the initial 16 'pattern on the initial 10 'sheet can be done using sublimable inks, following a process generally falling under the decal.
  • the 16 'motif composed of such sublimable inks is initially printed on any medium, and, by example, a paper backing.
  • a temperature on the order of 200 ° C, applied for a time of the order of 2 minutes, and under a pressure of the order of 2 to 4 bars may suffice.
  • the initial 10 'sheet is an aluminum sheet, we preferably provides anodization of this initial sheet 10 ' before applying the initial 16 'pattern, so that it is duly protected and that the 16 'motif penetrates better.
  • the anodized layer thus obtained can extend over 6 at 20 microns, depending on the quality of protection sought.
  • this sheet 10 ' is also preferentially subject initial to another operation, called clogging operation, to trap inside the previous anodized layer the inks forming this initial 16 ′ pattern.
  • this clogging operation comes down to an initial 10 'sheet immersion operation in a bath demineralized water to which a sealing salt is added, for example example that known under the commercial designation "HARDWALL", at a content of the order of 5 grams of salt clogging per liter of water, and whose pH is preferably set between 4.5 and 5.5.
  • a sealing salt for example example that known under the commercial designation "HARDWALL”
  • This clogging operation is in practice carried out at low temperature, that is to say at a temperature of the order from 25 to 30 ° C, and its duration is for example of the order of 20 minutes.
  • the initial sheet 10 ' is then subjected to a "deployment", that is to say to operations usual cutting and stretching necessary for such "deployment".
  • the scope of the invention is not limited to only structures formed of flat panels, but extends on the contrary as well to that volume structures, especially when such panels plans are more or less curved, curved or shaped.
  • the scope of the invention is not generally not limited to structures in expanded metal, but extends more generally to deformed metal structures projecting from a network mesh of deformations, let the meshes of this network be unidirectional, the deformations reducing for example in this case to simple parallel ribs, or whether it's of bidirectional meshes, the deformations forming by example in this case of simple local bosses.
