Definitions

  • the present invention relates to a method for manufacturing decorative products, in particular for wall applications, of the kind of various reproductions of graphic works, such as drawings, sketches, sketches, photographs, tables or the like, if necessary of articles.
  • the type of signs or objects to be applied against a wall such as coat hooks, height rods, or similar articles, having in common the ability to be generally flat to allow to be disposed against this wall, vis-à-vis screw from which they are suspended or fixed at an appropriate height.
  • reproductions are carried out in most constant rule on a rigid support, plan, paper, cardboard, material plastic, fabric possibly, without this list having by itself a limiting character, the only imperative being to be able to transpose and reproduce faithfully on such a support the original work with a sufficient reliability ensuring the suitable durability of the reproduction, that- these may further and where appropriate, include additions or decorative additions which may be made to the work reproduced, either because it is in the public domain, or by virtue of the Authorization of the Author.
  • these reproductions once made on the chosen medium, are most often arranged inside a presentation and support frame, ensuring the flattening of the reproduced work, usually in the case of paintings, drawings or the like, with partial overlap of the edges of the support by means of a "pass everywhere" cover, plain or decorated, which surrounds the reproduction on its support and forms a transition with the border of the frame surrounding the set.
  • a "pass everywhere" cover plain or decorated, which surrounds the reproduction on its support and forms a transition with the border of the frame surrounding the set.
  • the present invention relates to a method of manufacturing decorative products of the aforementioned kind, which avoids these drawbacks by eliminating, after prior production of the support on which the reproduction is postponed, the successive operations necessary to achieve its framing, with a separate cost but ultimately accumulated from these interventions.
  • the invention also relates to decorative products in the broadest sense, obtained by the implementation of the process considered.
  • this process in which the work to be reproduced is printed by any conventional means, on a flat support, in particular made of material thermoformable plastic is characterized in that it consists in carrying out simultaneously or later on said support in trompe l'oeil the drawing of a frame surrounding the reproduction of the work, in thermoforming the plastic material of the support in line with the drawing of the frame to make appear in the plane of the support a boss constituting a rod or peripheral structure, continuous or not, extending according to the profile of the frame in relief towards the outside relative to the plane of the support, to cut this support before or after during the thermoforming operation, according to the external contour of the frame, to invert the support to apply it on a support matrix keeping it flat, to inject or otherwise fill the hollow profile formed on the opposite side of the frame by a material capable of stiffening, then separating the support from the matrix to form a panel in one piece, having on one side the reproduction arranged in the middle of u drawing of the frame and on the opposite face, an entourage housed inside the frame
  • the method according to the invention therefore makes it possible, by a series of successive operations carried out on the medium of the reproduction itself, to directly incorporate therein the frame surrounding this reproduction and in total to provide a product eliminating any operation subsequent mounting and mutual centering of various independent elements, before carrying out their final assembly.
  • thermoformable plastic support in particular at the level of the frame
  • transfer of the work, original or adapted, that is to say incorporating any desired or authorized addition or modification, on the thermoformable plastic support, in particular at the level of the frame can be carried out by any printing process.
  • conventional in particular by photography, serigraphy, lithography, photoengraving, offset, decal or other transfer process, such process known per se having no direct impact on the present invention, from the moment when it makes it possible to reproduce the work on this medium under satisfactory conditions of fidelity and reliability.
  • the drawing of the trompe l'oeil frame around the reproduction can be made, either on a test used for the subsequent implementation of the reproduction and transfer process of the work on the thermoformable material support, or on the medium itself after the reproduction has been printed on it.
  • the frame can have any contrast effect with respect to the reproduction that it surrounds, by simulating by drawing any material, any texture, or any desired profile or dimensions, to integrate into or be reproduced from this reproduction. to distinguish.
  • the drawing of the frame may include, interposed between the reproduction and the peripheral strip, an intermediate cover, or "pass everywhere", transferred simultaneously or successively to the support.
  • the thermoformable plastic support is made of polyvinyl chloride, polyester, polypropylene, polycarbonate, ABS (acrylonitrile butadiene styrene), or any other equivalent material, having an appropriate relative rigidity and above all a good ability to serve as a printing medium for the reproduction to be transferred thereon.
  • the thickness of the support can be variable from one plastic to another, of the order of 0.3 to 3 mm, or even more, depending on the resistance sought for the support, in particular in tearing or vis- against shocks or spikes.
  • the reproduction on the support has a thickness which can be extremely limited, of the order of 0.2 to 0.8 mm, depending on the process. adopted printing, without these dimensions being in themselves limiting.
  • the support of thermoformable plastic material comprising the reproduction may be coated, before or after the thermoforming of the frame, with a thin layer of external protection.
  • a thin protective layer can be produced in the form of a transparent plastic sheet, applied or bonded to the support, or else obtained by projection or passage through a bath, followed by a drying step.
  • thermoforming of the support for the production of the frame is carried out in a mold, comprising a raised rib, the profile of which corresponds to that of the rod or structure to be produced in the support, the pressure application of the latter against the rib of the mold causing in the support an indentation delimiting the outline of the frame.
  • thermoforming mold comprises a rigid seat provided with the rib in relief in line with the location of the frame to be formed, the support being applied against the seat by means of a press plate, comprising, where appropriate, like the seat, heating means capable of ensuring the deformation of the support under the combined effect of pressure and temperature.
  • the seat of the mold may include pneumatic suction means to perfect the application of the support against the frame-forming rib.
  • the support matrix on which the support is applied comprising the frame after cutting according to the outer periphery thereof, has a hollow external imprint receiving the frame rod and a flat inner part in contact with the reproduction carried over to the support.
  • this inner part includes a protective coating, to avoid any deterioration of the support in contact.
  • the filling of the frame after thermoforming, inside the rod received in the imprint of the support matrix is carried out using a material chosen from polyurethane foam, an epoxy resin or plaster, or more generally a thermosetting material, preferably quick setting, neutral with respect to the plastic of the support.
  • a wall fastener of any type is placed or embedded in the filling material of the rod, before it hardens.
  • the finishing of the product can be carried out by applying an external protective sheet against the face of the support opposite to that comprising the reproduction, this sheet being able to consist of a coating of plastic material, a sheet of paper, cardboard or other.
  • the reference 1 designates a printing medium, consisting of a sheet 2 of a thermoformable plastic, of the polyvinyl chloride, polyethylene, polypropylene, polycarbonate, ABS or other type.
  • This sheet has an appropriate thickness, which can be between 1 mm or less and 4 or 5 mm, depending on the nature of the plastic material and the printing process used to transfer onto the surface of the sheet 2 any reproduction 3 .
  • This sheet has good resistance to tearing effects and to impact or attack by a sharp object.
  • the printing of the reproduction 3 on the support 1 can be carried out by any conventional method well known in the art, making it possible to transfer safely, reliably and faithfully, onto the surface of the sheet 2 a drawing, a sketch, a sketch, a photograph, a table, with in any case a report of the forms, dimensions and colors of the model, which can itself be an original work or a prior reproduction thereof.
  • the reproduction of the reproduction on the sheet of the support can be carried out identically or on the contrary by making adaptations or modifications, desired and if necessary authorized.
  • This reproduction can be made flat or include hollows or reliefs depending on the design itself and the effects to be manifested.
  • the thickness of the reproduction thus reported on the support sheet is between 0.2 and 0.8 mm.
  • the next step consists in drawing or transferring onto sheet 2 the drawing of a frame 4 surrounding the reproduction 3, this drawing of the frame being able to be carried out prior to the postponement of the reproduction itself and in turn transposed onto the support, or be performed on the test to be reproduced before it is transferred to the sheet.
  • the frame 4 can have any suitable shape and in particular in the most general case include longitudinal parts, forming together around the reproduction the representation of a rod 5, the latter term being taken in the broad sense.
  • the frame may itself include, in its longitudinal parts as well as in its corners 6, various extensions, decorations or modifications, the presence of which has no effect on the implementation of the method according to the invention.
  • the frame 4 can be drawn in any color, preferably but not necessarily contrasting with the colors of the reproduction 3 as in a usual table.
  • a neutral border (not shown on the drawings) simulating a cover of the "passe-partout" type, generally provided in tables or reproductions intended to be presented while hanging against the surface of a wall or the like.
  • a protective layer 7 consisting of a thin film of a transparent plastic material, for example of the "Mylar” type or the like .
  • this protective coating is not essential; as a variant, the thin film can be produced by spraying or spraying onto the surface of the support 1 carrying the reproduction 3 or alternatively by soaking or passing through a bath, followed by a drying step.
  • thermoforming operation according to a process which is also well known in the art, Figure 3 therefore giving only '' a completely schematic representation of the adopted process. Note however that this thermoforming operation could be performed before the installation of the protective coating 7 described above.
  • a mold consisting of a solid seat 8 having a raised lateral rib 9, the profile of which is determined to ensure, in line with the frame 4, in particular in the longitudinal parts 5 thereof, a raised boss similarly, the thermoforming of the sheet 2 allowing it to closely match the profile of the rib 9 by pressing tightly against the seat 8.
  • the application of the sheet 2 on the seat 8 is produced by means of the plate of a forming press 10, with an energetic suction of the sheet 2 through this seat in the direction of the arrows 11, the seat being for this purpose pierced with a plurality of channels (not shown).
  • the seat 8 and the plate 10 of the press comprise heating means, for example electrical resistances and a regulation system, making it possible to bring the temperature of the sheet 2 to the level necessary to obtain its deformation.
  • the central part of the seat 8 against which the reproduction 3 produced on the sheet 2 is applied may be coated with an appropriate protective layer, in order to avoid damaging it during the operation. thermoforming.
  • the next step consists, after removing the sheet 2 thus conformed to the right of the frame 4 drawn around the reproduction, to cut the extreme edges of the sheet at the periphery of the frame, horizontally or vertically at by means of cutters schematically illustrated at 12 in this figure, which may be constituted by circular or band saws, or by any other similar means of the cutter, punch, laser or pressure jet cutting machine type , Or other.
  • the support 1 thus prepared and cut is then turned over on itself and put in place in a support matrix 13 (FIG. 5) comprising a hollow imprint 14, shaped in its lateral sides 15 so as to accommodate the boss forming the rod 5, 6 of the frame 4, strictly reproducing the shape of the rib 9 of the seat 8.
  • the hollow form delimited by the frame 4 is filled by means of a material 16, chosen to ensure proper stiffening of the latter.
  • this material can consist of polyurethane injected under pressure inside the frame, the matrix 13 being in this case covered with a cover (not shown) leaving only space, between itself and the matrix, the space in which the injection is to be carried out .
  • the frame can be filled with a thermosetting resin, of the epoxy resin type, or even with plaster or another quick-setting material, capable of solidifying by hardening, while being neutral with respect to the plastic material of the support which it cannot therefore affect.
  • the final step consists, after having embedded in the material 16 prior to its final hardening, a fastener 17 allowing the frame to be hooked subsequently against a wall or similar structure, to remove the product from the matrix 13, as shown in the Figure 6.
  • the clip 17 can be implemented in another way, for example using screws, gluing or any other means.
  • a protective sheet 18, of paper, cardboard, plastic or other material is advantageously behind the frame.
  • the method according to the invention can naturally be exploited, not only for producing the outline or the framing of the work during the thermoforming phase, but also part of the image or of the decorative patterns contained in this framing.
  • the method according to the invention has the advantage which results from the simultaneous production of a reproduction and its setting, allowing a considerable reduction in costs vis-à-vis comparable products traditionally produced. .
  • the possibility of making the frame directly around the design transferred to the support offers great creativity with regard to the shape, colors and structure of this frame.
