- reconfiguration is understood to include in particular decoration or personalization (customization) by means of themes, visual effects and textures; a visual aid to musical learning, for example by note names or symbols; or as the establishment of a communication and / or promotion medium.
- the invention relates to the application of one or more stickers (sticker) for the purpose of reconfiguring musical instruments.
- Musical instruments generally have a plurality of technical surfaces. These are in particular surfaces whose vibration makes it possible to reproduce the sound of the instrument, delicate and fragile surfaces, and / or surfaces made of living-type material needing to “breathe”, namely to be traversed by air, so as not to deteriorate quickly. Some technical surfaces have fragile coatings or varnish which complicates the use of stickers.
- stickers with glue poses a problem in that glue residues permanently block the pores of technical surfaces or deteriorate the coatings.
- the sticker covers the surface aesthetically, including in relief.
- Some stickers have a stiff, preferably one-component polymer structure and with a rather dry and sticky viscoelasticity only to a very clean and smooth surface, which results in air bubbles in use. Many of them do not stick to a surface that is not completely clean, and fear heat and poor storage (in the face of the unlimited advantage over time of the invention) which generates irreversible wrinkles.
- the rigid side prevents application to circumvolutive surfaces (because it is deformable and not stretchable) and almost completely decreases adhesion on surfaces from a slightly dirty or dusty state.
- some stickers have a micro-perforated adhesive structure or with micro-voids or multi-holes with a suction effect adhering by suction allowing adhesion on smooth to slightly less smooth surfaces, but they are very sensitive to soiling and dust quickly sticking to it. Also, this feature reveals a non-shiny finished surface with a hammered effect that lacks the finished aesthetic of the product. In addition, this material is not stretchable and is sensitive to tearing. Finally, this same material leaves to the touch an unpleasant sticky feeling and strongly affects the absorption of fat and dust.

- the invention relates to the reconfiguration of musical instruments 1. In the context of the present, it is in particular the decoration or personalization (customization) of musical instruments 1.
- the reconfiguration within the scope of the invention is done, for example, by means of themes, visual effects and textures; or as a communication and / or promotional medium.
- the promotion can for example be a promotion of a musical group or a brand, in particular the presentation of a logo, a name, a slogan, a price ...
- the reconfiguration can also allow one or more stickers to be used as a visual aid to musical learning, for example by note names or symbols.
- the inscriptions can be made by printing (in particular by superposition) or inlay (in particular by molding).
- “technical surface” is understood in particular surfaces whose vibration makes it possible to restore the sound of the instrument, delicate and fragile surfaces, and / or surfaces made of living material, such as wood (or metals). , needing to "breathe” ie to be traversed by air, so as not to deteriorate rapidly.
- the instruments need to be in good hygrometric and thermal condition to be stored. So the air must be healthy to best conserve the materials of the instruments.
- a sticker still applied or having left glue will affect the non-passage of healthy air and will accelerate aging.
- varnishes become more and more fragile and less resistant over time, they peel off easily and the removal of stickers with glue will automatically cause it to be removed.
- the glue poses a problem in that glue residues permanently block the pores of technical surfaces 2 of musical instruments 1 or deteriorate the coatings thereof.
- certain technical surfaces 2 may have convolutions (curves and shapes), or positive or negative reliefs. It is important that the sticker covers surface 2 aesthetically, including in reliefs and on convolutions, avoiding folds.
- a specific configuration of the sticker design also helps adhesion on the more complex, circumvolutive and large shapes.
- the strategy is to make void zones to help surface adhesion in contact, decreasing the tension in the silicone material as less solid material. This results in easier stretching.
- an A4 silicone moucharabieh will be more stretchable than an A4 sheet of (full) silicone of the same thickness.
- the invention proposes to apply new stickers 3 (sticker) for the purpose of reconfiguring musical instruments 1.
- the invention relates to a process for reconfiguring a musical instrument 1, which may be those composing a symphony or philharmonic orchestra such as a guitar, a piano (body and / or keys), a violin, a trumpet, etc.
- a symphony or philharmonic orchestra such as a guitar, a piano (body and / or keys), a violin, a trumpet, etc.
- the method preferably comprises a step of preparing the technical surface 2 to be reconfigured. This is in particular a cleaning of said surface 2 to remove dust residues, for example.
- the method according to the invention comprises a step of applying one or more stickers 3 to at least one technical surface 2 of the musical instrument 1.
- the instruments 1 are for some "alive and breathing". Wood or metals need a specific varnish (nitrocellulose, polyurethane, polyester, etc.) or a protective lacquer that lets them "breathe” so that they do not age prematurely and also allow sound to be transmitted perfectly.
- varnish covers 3 aspects: resistance, aesthetics and sound.
- the sticker is both deformable and shape memory under all thermal conditions acceptable for the instrument, in particular from -20 ° to + 150 ° Ce probably even more normally.
- the sticker is very resistant to sudden changes in temperature.
- the sticker has good adhesion to avoid detachment, especially at the ends of the sticker.
- Sticker 3 fulfills all these objectives and allows you to customize Instrument 1 without depositing or penetrating glue and solvent on the materials, and moreover, they do not distort the hearing.
- the application of said sticker 3 is done without glue.
- the application of the sticker does not induce a sticky residue clogging the pores of technical surfaces 2 or altering delicate technical surfaces 2. This results in better preservation of technical surfaces 2.
- the sticker 3 comprises an elastomer layer configured to come into contact with said technical surface 2 and to adhere to it in a reversible manner without the application of glue.
- said sticker can be applied in a reversible manner, can be removed to clean the surface 2 of the instrument 1 or let it breathe. This can be illustrated by Figure 8A.
- the sticker 3 has sufficient residual elasticity to allow vibrations of technical surfaces 2 so that the sounds are less altered while optimizing its hold when the sound is emitted.
- said sticker can be stretched so as to make it aesthetically match the technical surface reliefs 2.
- the method further comprises a stretching step during the placement of the sticker 3. This step makes it possible to match the positive or negative convolutions and reliefs of the technical surface 2. This can be illustrated. by Figure 6A to 7C.
- the invention allows both stretching, unlimited repositioning, cleaning, change of design, 3d aspects (relief, textures, etc.), light-reflecting, phosphorescent effects, collages, overlays and stacking, a possibility of writing or drawing on it... and a product that is thicker and more qualitative to the touch and to wear.
- Stretching may not be necessary, especially for substantially flat technical surfaces. For curved surfaces stretching may be necessary.
- the method further comprises a cutting step preferably before the application of the sticker.
- it is a cutting using a tool such as scissors or a cutter with reference to a felt-tip or marker / pencil tracing specifically designed so that the tracing is erasable using a kit. specific cleaning.
- Tracing can be done against the instrument.
- the resistance of the silicone will not drive the tip of the pencil into the material of the instrument.
- the cutting of sticker 3 is preferably done outside the instrument.
- Cutting can be done for large format boards. It is preferably not needed for already drawn and finished designs, such as the wolf's head (figure 5), or the eighth note (figure 4), or the Japanese landscape (figure 3C). These can be made in different sizes ready to use for all instruments. In general, we will talk about the format and type of product b) for these stickers; and of format and type of product a) for cut-out stickers such as those in Figures 2A and 2B.
- the invention further relates to a sticker 3 for reconfiguring a musical instrument 1.
- a sticker 3 for reconfiguring a musical instrument 1. This is in particular a sticker perfectly configured for implementation for a reconfiguration method as described above.
- the sticker 3 comprises an elastomeric layer configured to contact at least one technical surface 2 of the musical instrument 1.
- the sticker 3 is preferably an elastomeric sticker.
- the elastomer layer is configured to adhere to technical surface 2 reversibly without the application of glue.
- the elastomer layer does not include glue or any other substance liable to leave sticky residues after removal of the sticker 3. More particularly, the elastomer layer is not used with this type of sticker either. glue or substance.
- the sticker 3, in particular the elastomer layer is configured to have an extremely smooth surface.
- the layer is for example the result of a specific molding sought to achieve this non-slip texture generating a high coefficient of friction that can hold vertically and even upside down (towards the ground).
- the sticker depending on the preferred variant has good performance under standard outdoor climatic conditions (wind, rain, etc.), as well as on oily or dusty instruments.
- the basic principle of the sticker 3 is to make it on at least one of its surfaces completely smooth, allowing it to adhere to any support of the same zero roughness, such as varnishes or lacquers on instruments 1. in wood, metals, plastics ...
- the sticker 3 allows a perfect adhesion by following the shapes (by its elasticity) in particular by simple pressure of the sticker with the fingers on the receptive surface, leaves no trace of glue (because there is none), and leaves easy to glue and take off without resistance, always with the hands.
- Sticker 3 does not damage the varnish of musical instruments 1 and other fragile surfaces 2 that can be decorated or applied with a sticker.
- a collage is more effective with a clean sticker. It is washable with water for dust removal and with a cleaning solution for grease removal. Drying can be done in the open air or with a cloth (microfiber) that does not deposit any fiber to gain adhesion efficiency.
- the structure of the sticker includes a glue-free elastomer with elasticity that helps limit air bubbles in use.
- the possible fineness of the finished product (less than half a millimeter) offers the visual, virtually no relief and a particular choice of aesthetics (ultra flat).
- the use of the instrument with the sticker is also facilitated by the non-relief and the exceptional adhesion to the substrate (varnish, lacquering, etc. of the instruments).
- This particularity offers a very adhesive bonding on a clean surface, in particular by the very low weight of the sticker and the origin of the material having a viscoelasticity ratio targeted mainly on strong adhesion rather than elasticity. Repositioning remains unlimited if no deformation is applied. Cleaning with water is still possible.
- gluing on the product can be done in order to add volume in superposition.
- this extra thickness function requires the added part to have the same elasticity as the lower part. If the presence of an adhesive (glue) is to be applied, it should be contained only on the surface bonding them. Thus the product will become a multilayer with volume and the basic advantages of this variant.
- the sticker according to another variant of the invention includes an elastomer chosen to allow adhesion without adhesive significantly on very clean surfaces, and being stable at temperatures of current use.
- This second variant by the design of multilayers of polymer films with vacuum, makes it possible to have a sticker that is positioned almost automatically by its approach on the substrate while being sucked into it.
- the non-stretchable and rather rigid side of the product brings the advantage of practically no appearance of bubbles and the removal of these by simple passage of the hand from the center of the sticker outwards.
- the application becomes easier to implement by applying it with hold and keeping the shape of the design on the entire sticker. Membership lasts as long as no peeling is done. The removal is done without force by simply peeling off one corner of the sticker with the tip of your fingernail. Repositioning remains unlimited if no deformation is applied. Cleaning with water is still possible.
- the sticker of the invention includes an elastomer to provide grip and prevent slippage.
- Another variant with a micro-perforated or multi-hole adhesive structure with a suction effect adhering by suction allows adhesion on smooth but also more difficult substrates such as: on slightly porous, rough, matt, little dusty, little greasy and used, matt varnishes, instruments frosted or without varnish. This material maintains thickness and can be molded to effect shapes and textures.
- an additional element can also be added to it by gluing on its surface.
- the material accepts wet cleaning allowing the product to be remanufactured.
- the flexibility of the material offers application on circumvolutive surfaces.
- An ideal viscoelasticity ratio is to be put in place in order to maintain the main objective of the very sticky property of the sticker on so-called difficult surfaces, and the elasticity for application on technical circumvolution surfaces. In addition, it also retains the property of not sticking with glue.
- the elastomer layer comprises silicone.
- the silicone sticker 3 is capable of being used for various solutions: It can be a medium for advertising, information ... because any pattern, text or design can be printed on it or molded and linked next to each other.
- the elastomer layer comprises RTV Polyaddition silicone.

- the negative printing can be done by molding made during casting. This can be illustrated by Figure 8C.
- the external / sensory aspect of the sticker obtained can have a glossy surface, a mat surface, positive relief (s), negative relief (s), with empty areas, textures, or a combination of several of these aspects.
- the desired viscosity corresponding to a hardness (shore A) of approximately 33 shA, offers sufficient crushing power for daily and normal use of the sticker.
- This flexibility is sought after for its high adhesive and stretchable side.
- the preferred tensile strength (approximately 4.7 N / mm2) provides sufficient tensile strength for daily and normal use of the sticker for its application. In use, this limits deterioration of the materials because no cracks in the material must be present so as not to cause its tearing extension by traction. A range between 2 and 8 N / mm2 can be used.

- the glass plate offers the visualization of air bubbles on the underside by transparency.
- the lower part of the mold will be the visible part of the sticker.
- a sticker with a smooth (non-mat) surface 2 on the visible face will have the particularity of being reversible and can be positioned on both sides on instrument 1.
- the mold 5b, 5c is for example produced by a 3D printer (or other PVC or metal profile injection machine).
- the mold constitutes the peripheral rim serving as a container of the finished product for the casting of the sticker 3.
- a mold postproduction step can be done by sanding over the physical defects during creation.
- the part of the mold (in relief) obtained can be glued or welded (depending on the material) to the support here in glass.
- Some parts may have insulated internal walls (such as islands) to create voids in the finished product or, for the insertion of a different finish color or texture (done later).
- the mold for the sticker in Figure 5 includes an island to form the eye 7.
- a mold formed in one go can also be made, comprising both the base and the outline.
- the expected finishes must be determined.
- the molding materials and the type of casting / injection / bending... will be chosen according to the expected finish.
- the mold is preferably extremely flat in order to have the particular feature of allowing the casting rule 8 to pass.
- the silicone is spread evenly, smoothly and over the same thickness. Casting and equalization can be done manually or robotically.
- the first embodiment is similar to a one-shot casting with a finished product of the mono-finish / texture or mono-color type.
- a board 5a (format / type of product a)) having several mold parts 6, is used.
- it is a set of several molds 6 joined together to make a large sticker.
- This embodiment can be illustrated by Figures 2A and 2B.
- the first embodiment makes it possible to obtain a mono-color or mono-texture structure with or without parts 6, 7. It is made by direct casting.
- FIG. 2A illustrates a sheet of A4 format (format / type of product a)) comprising a set of molds 6 joined together.
- the shape of the sticker is poured in one go on this mold consisting of a base and multi-islands 6 which will provide voids when removing the finished board.
- the resulting sticker can be applied to a guitar such as the one shown in Figure 2B.
- molds 5b, 5c are used. This embodiment can be illustrated by Figures 3A to 3C.
- the second embodiment achieves a multi-color structure. It is done by pouring in two stages, or even more.
- Fig. 3D sticker on the left.
- said mold is preferably 0.7 to 2 mm thick, more preferably 1 to 1.5 mm thick to have a desired sticker thickness.
- an elastomer composition of a first color must be poured (mold of Figure 3A for example), then dried.
- the first part of the sticker thus obtained is placed at least partially in a second mold, for example in the mold of FIG. 3B.
- the second casting will take place in the second mold, here larger than the first so that the new silicone freezes around the first product already on hold.
- this method can be duplicated and so on.
- the method is the same as the second.
- the third embodiment achieves a multi-texture structure.
- this makes it possible to produce a sticker combining several complex structures. It is done by pouring in two stages, or even more. In particular, the smooth layer is poured first.
- This method makes it possible to avoid during the pouring of the second part of the product (part of the non-smooth surface), lifting of the first part of the product.
- the principle of making the smooth part first offers the use of its adhesion characteristic as a means of attachment to the base of the (glass) mold and thus prevents infiltration of the silicone from the second casting downwards.
- the pouring of the non-smooth zone (s) can (can) be done on the defined surface (them) relating to and bonded to the smooth product (zone) currently in place.
- This technique can be applied with or without different colors.
- the smooth texture shown on the left of the figure differs from the 3D texture of the middle figure which includes a negative + smooth relief.
- these figures differ from the figure on the right which includes a matte + smooth texture.
- the mold must be composed of a surface of texture x (not smooth) and adjacent to a minimum of texture y (smooth or not smooth) with a one-step casting.
- texture x not smooth
- y minimum of texture
