Definitions

  • the invention relates to a process for realising a matrix for realising a tile.
  • a further object of the present invention is a tile, or more in general a cladding element, obtained with the above-mentioned matrix.
  • the matrix and the realisation process therefor enable a tile to be obtained which can be used in any dwelling and/or public or private infrastructure, such as for example health care structures, commercial, industrial structures, transport structures and the like.
  • the present invention is applicable to the building sector and can also be used in the realisation of places requiring special and/or characteristic aesthetic improvement or effects.
  • the prior art comprises tiles having an in-view surface which is provided with a plurality of reliefs that define a single treading plane.
  • the reliefs each exhibit a crest from which inclined flanks extend which define, in pairs, an alternated series of reliefs adjacent to respective gullies.
  • the gulleys are intercalated with reliefs such as to exhibit, in transversal section, a sawtooth profile developing along the in-view surface of the tile.
  • the inclined flanks of the reliefs exhibit concavities or jags which produce and define two difference images or figures which are selectively perceived according to a point of observation of the tile.
  • the Applicant has found that in order to obtain figures and ornamentations of a sufficient sharpness, the crests of the above-mentioned reliefs have to be especially distanced, delimiting there-between corresponding gulleys of considerable width and/or particularly deep. Obviously on increasing the width and depth of the gulleys between the reliefs, the degree of jaggedness of the treading surface defined by the tile also increases, which transmits sensations similar to those of an uneven treading plane.
  • a force applied on the in-view surface of the tile might cause breakage thereof with the breakage starting from the gully end.
  • the bottom tiles in a stack can break for the same reasons as above.
  • the Applicant has found the complete perception of a figure, for example an indication of an emergency exit, possible only in a case in which the observer is positioned such that his or her point of observation is substantially perpendicular to a series of inclined flanks on which the image is reproduced.
  • the technical task at the base of the present invention is to provide a process for realising a tile which can substantially obviate the cited drawbacks.
  • an important aim of the invention is to provide a process for realising a tile which defines a uniform treading plane despite the presence of reciprocally-intercalated reliefs and gulleys.
  • a further aim of the present invention is to provide a process with reliefs and gulleys which do not seriously weaken the mechanical resistance of the tile to flexion stress.
  • a further aim of the present invention is to originate a process which grants the tiles a double-face aesthetic effect, which is effective even at different angles of viewing thereof.
  • a further aim of the invention is to provide a process by means of which it is possible to give the tiles ornamentations and/or illustrations which can transmit a three-dimensional effect which is variable according to the point of observation thereof.
  • the object of the present invention relates to a model for realising one or more tiles (not illustrated).
  • the process which is object of the present invention first includes a three-dimensional model stage of the tile to be produced.
  • the design of the tiles to be produced is advantageously actuated by means of an electronic device for three-dimensional design (not shown in the figures).
  • the model comprises realisation of a starting three-dimensional model 1, provided with a substantially plate-shaped base 2 exhibiting a main surface 3 from which at least a geometric solid 4 develops.
  • a plurality of solids 4 are realised which project from the main surface 3.
  • the solid 4 developing from the base 2 is an arrow which can be subdivided into a first portion 4a, defined by a parallelepiped, i.e. the leg of an arrow, and a second portion 4b, defined by a triangular-base prism.
  • any regular or irregular solid can be reproduced on the main surface 3, as well as writings, motifs and any kind of decoration.
  • the starting three-dimensional model 1 is sub-divided according to a plurality of pre-defined sub-division planes 5 ( figures 1 and 2 ), such as to give rise to a plurality of sections 6, each different to another.
  • the sub-division planes 5 are preferably substantially parallel, so that the above-mentioned sections 6 exhibit respectively parallel surfaces.
  • the sub-division planes 5 are advantageously substantially perpendicular to the main surface 3 of the base 2, so that the surfaces of the sections 6 extend substantially vertically.
  • the sub-division planes 5 are preferably equidistant in order to give the sections 6 a same thickness.
  • an image 7 of the starting three-dimensional model 1 is projected onto a workpiece plane 8 ( figure 3 ).
  • the image 7 is advantageously obtained by tilting each section 6 of the starting three-dimensional model 1 to a predefined angle which is such as to ensure that each section 6 rests on the workpiece plane and thereafter by tracing a line 9 on the workpiece plane 8, which line 9 corresponds to the profile of the respective crest 6a of the tilted section.
  • Each section 6 is preferably tilted by means of a rotation to an angle of about 90° about a respective rotation axis arranged on an opposite side with respect to the crest 6a.
  • the lines 9 are thickened to an amount pre-defined by the designer.
  • a respective relief 10 is extruded, which relief 10 extends from the workpiece plane 8 ( figure 5 and 6 ), preferably perpendicular thereto and with a predefined thickness.
  • the reliefs 10 are advantageously extruded such as to exhibit thicknesses which are equal, with respective crests 10a preferably equidistanced from the workpiece plane 8.
  • the reliefs are extruded such as to be raised above the workpiece plane 8 by about 1 mm.
  • each relief 10 is inclined with respect to the workpiece plane 8 in order to define respective gullies 11, having a V-shape and being intercalated with the reliefs 10.
  • the inclination of each flank 10b of each relief 10 preferably defines, together with the workpiece plane 8, at least an angle comprised between 1° and 89°, preferably 45°.
  • the lowering is performed by intersecting the reliefs 10 with a cutting plane, preferably parallel to the workpiece plane 8, and interposed between the workpiece plane 8 and the crests 10a.
  • a matrix 14 ( figure 7 ) is then formed, which faithfully reproduces the definitive three-dimensional model.
  • the formation of the matrix 14 is advantageously realised on a block of raw material, preferably metal, by removal of matter.
  • the block of raw material is suitably worked by one or more shaving machines which recreate the shape of the definitive three-dimensional model.
  • the shape of the in-view surface thereof is advantageously modelled in negative by using a counter-shaping material (not illustrated as of known type).
  • the counter-shaping material thus exhibiting the negative representation of the image of the in-view surface of the matrix 14 is then fixed on at least a press die for forming the in-view surfaces of the tiles to be produced.
  • the negative image of the definitive three-dimensional model can be realised directly on the press die by means of one or more material-removing operations.
  • the three-dimensional model could also be realised by dropping, extrusion or pressing.
  • Dropping involves predisposing a special two-face die, upper and lower faces, which is provided with a hole for dropping the forming mixture.
  • Extrusion involves extruding the base shape of the tile through the extrusion matrix and cutting the base shape when the desired length has been attained.
  • Pressing can be done using two different methods, dry pressing or damp pressing.
  • the formation of the matrix 14 or the press die is done by forming a base structure 15 which develops substantially on a preferential lie plane such that the base structure 15 is provided with a bottom surface 16 and an in-view surface 17 arranged on the opposite side to the bottom surface 16.
  • the above-mentioned stage of matrix formation comprises the formation, at the in-view surface 17, of a plurality of reliefs 18, each projecting from the base structure 15 to a predetermined amount and exhibiting a respective crest 18a facing opposite to the bottom surface 16.
  • the crests 18a of the reliefs 18 are substantially equidistanced from the base structure 15 of the matrix 14, so that the tiles made by the use thereof exhibit a single treading plane.
  • the formation of the reliefs 18 comprises the formation of at least a first zone 19 having substantially parallel and equidistant reliefs 18, and the formation of a second zone 20 having reliefs 18 orientated transversally with respect to the reliefs 18 of the first zone19.
  • the formation of the reliefs is preferably done by realising a plurality of first zones 19 with reliefs 18 that are substantially parallel and equidistanced, and a plurality of second zones 20 having reliefs 18 orientated transversally with respect to the reliefs of the first zones 19.
  • the reliefs 18 of the second zones 20 can advantageously be distanced to a different amount with respect to the distance running between the reliefs 18 of the first zones 19.
  • the reliefs of the second zones 20 can either develop along substantially straight directions or along curved trajectories, thus defining arched profiles.
  • the reliefs 18 of the second zones 20 can develop substantially parallel or in reciprocally inclined directions. It is further possible that the reliefs 18 of the second zones 20 might exhibit at least a first tract that is substantially parallel to a respective first tract of a relief 18 of the respective second zone 20 adjacent thereto, and at least a second tract which is inclined with respect to the adjacent relief 18.
  • the reliefs 18 of the second zones 20 can advantageously be equidistanced or can exhibit differentiated distances.
  • the in-view surface 17 and the reliefs 18 of the first and second zones 19 and 20 are realised in a predetermined order.
  • the use of the above-described matrix 14 enables realisation of a press die exhibiting a negative impression of the design of the in-view surface 17 of the design, so that the tiles obtained by means of the die are provided with in-view surfaces which are identical to the surface of the matrix 17, i.e. provided with first and second zones 19, 20 having different reliefs 18.
  • the present invention solves the problems encountered in the prior art and achieves the set aims.
  • the proposed process enables tiles to be realised which exhibit a single treading plane which transmits the sensation of a continuous plane without jags.
  • the tiles obtained by the above-described process exhibit ornamentations or graphic representations which give a three-dimensional effect to the in-view surface.
