- the covering element 10 uses a first material M1 capable of selectively reflecting different visible wavelengths according to the stress applied to it.
- a first material M1 capable of selectively reflecting different visible wavelengths according to the stress applied to it.
- materials capable of creating so-called structural colors. These materials are composed of at least two elements with different refractive indices and periodically alternated.
- the size of the elements is of the order of magnitude of the wavelengths of light so that optical interference phenomena (constructive and destructive waves) are created which lead to the selective reflection of certain wavelengths . Interference phenomena and therefore the colors reflected depend on the size of the periodic lattice and the refractive indices of the at least 2 selected elements.
- structural colors there are several examples of structural colors. We can cite: butterfly wings, opals.
- This type of material can also be synthesized by techniques known to those skilled in the art. art. Synthetic photonic crystals are generally produced by orderly assembling mono-dispersed and bi-material spheres (with 2 different refractive indices at the heart and at the periphery).
- the periodic network thus formed is then frozen by UV polymerization.
- a second method of manufacturing photonic crystals consists of creating nanometric-sized "pads" on flexible thin film (typically a sheet of PDMS).
- PDMS flexible thin film
- researchers from the University of California Berkeley fabricated rows of silicon pixels by lithography techniques, which they then encapsulated in 2 sheets of PDMS ( Flexible photonic metastructures for tunable coloration, Optical Letters, 2015, p255 ) to lead to a thin and flexible film which can change color at will under the effect of small deformations.
- the periodic network can then be modified by varying the geometrical dimensions of the material and it is then possible to obtain a material with structural colors which change in a controlled manner when the material is mechanically stressed.
- These geometric dimensions are modified by applying a constraint on said material. These constraints can be stretching, compression, a twist, a pinch or any other constraints allowing a modification of the shape and / or dimensions of the material.
- This first material M1 can then be in the form of a more or less thick film or be directly integrated into the substrate forming the covering element 10.
- a first configuration allows the first material M1 to include only a film or a so-called opal strip obtained by the techniques described above.
- said first material M1 comprises the so-called opal film assembled on a flexible film.
- said first material M1 comprises the opal film encapsulated in two flexible films.
- the flexible films are preferably PDMS films or thermoplastic films, preferably polyurethane thermoplastic films
- the covering element 10 according to the invention must be provided, in addition to the support 12, with a device 14 making it possible to apply a stress to the first material M1 to cause it to change color.
- the covering element 10 is configured so that the support 12 and the device 14 making it possible to apply a stress to the first material to make it change color are one and the same element. It is then understood that the support is capable, by its characteristics, of being manipulated so as to generate a mechanical stress on the first material M1.
- the covering element 10 is a bracelet 30 called “slap strap” or “slap band” in the Anglo-Saxon version.
- a bracelet 30 is composed of a bistable metal strip 32 serving as a support 12.
- the bracelet 30 can be laid flat by tensioning the bistable metal strip 32 and then wound again around the wrist by snapping the bracelet.
- This bistable metal strip 32 can then be coated with a protective layer 34.
- This protective layer 34 can be an overmolded plastic material or a film or ink which hardens in order to improve its aesthetics as visible on figure 3a .
- the first material M1 is arranged on this bistable metal strip.
- the first material is arranged to cover the entire surface of the bracelet 30.
- the first material M1 can then be in the form of a more or less thick film which can be glued and / or sewn and / or assembled by gluing, ultrasonic welding, laser welding, infrared welding or extruded directly onto the bistable metal strip 32 as visible on the figure 3a or even molded onto the support 12.
- a protective layer 34 (varnish or thermoplastic) can optionally be applied over it.
- the first material M1 can then be placed either on the metal strip 32 or on the protective layer 34 of the bistable metal strip 32 as visible on the figure 3b .
- said material M1 is deposited on the bracelet 30 and then overmolded with a transparent TPU type thermoplastic.
- said first material M1 comprises an opal film encapsulated in 2 transparent thermoplastic films (TPU type) and the material M1 is assembled to the bracelet by thermal welding techniques.
- TPU type transparent thermoplastic films
- the first material M1 is visible at certain specific locations on the bracelet.
- the first material M1 is placed on the bistable metal strip (sewn, glued, overmolded, assembled or extruded) then a second layer 35 (perforated leather, thermoplastic, ...) is placed so as to reveal the first M1 material as visible to the figure 3c .
- the bistable metal strip 32 changes from one state to another, that is to say from the state in which the metal strip is under tension to the state in which the metal strip 32 does not is not energized and is wound, a stress variation occurs on the metal strip.
- This stress variation is transmitted to the first material M1.
- the first material M1 is capable of reflecting different wavelengths according to the stress which is applied to it. Consequently, when the slap bracelet 30 goes from one state to another, the variation in stress allows the first material M1 to reflect different wavelengths and therefore to have a bracelet having different designs depending on whether it is wound or not.
- the support 12 and the device making it possible to apply a stress 14 to the first material M1 to make it change color are dissociated and the stress is applied to the first material by means of a M2 material capable of seeing its volume vary as a function of a physical quantity, this physical quantity possibly being temperature.
- the material M2 is a liquid with a boiling temperature at atmospheric pressure of between 0 and 60 ° C. Under these conditions, when a temperature higher than the boiling point of M2 is applied to the covering element, the material M2 goes into the gas phase and thus sees its volume increase.
- the material M2 is ethyl chloride, butane, propane or a mixture of these compounds.
- the support 12 comprises at least one recess 40.
- This at least one recess 40 is used to place a capsule-piston system 43 and the material M2 therein.
- This capsule-piston system 43 sealed to the material M2 consists of a half-shell 44 and a piston 45 as visible on Figures 4a and 4b .
- the recess 40 is closed by a film 42 made of the material M1 or carrying the material M1. Consequently, when the temperature increases, the volume of the material M2 increases and acts on the piston 45.
- the piston 45 has a surface external rounded which comes into contact with the film of said material M1 when the piston is in the high position. In this way, when the piston 45 is pushed by the material M2, it comes to stretch the material M1 which then changes color.
- the piston capsule 43 thus formed is then placed in a recess 40 of the covering element.
- This piston capsule 43 can be glued, driven out, welded, screwed or even crimped into the recess to be held there.
- the covering element is incorporated into a thermoplastic component of the portable object (for example bracelet, dial, watch case, etc.) and the thermoplastic component of the portable object carrying the 'covering element 1 is directly overmolded on the piston capsule 43 thus forming the recess 40. In this case, very good adhesion is obtained between the covering element and the portable object in which it is integrated.
- said first material M1 comprises an opal film encapsulated in 2 films of transparent thermoplastic (TPU type) and the material M1 is assembled for example by heat welding or by bonding.
- TPU type transparent thermoplastic
- This configuration advantageously makes it possible to produce recesses 40 each accommodating a piston capsule 43 as visible on the figure 4c , these capsules can include specific and different M2 materials.
- the variation in coloring of the material M1 capable of reflecting different wavelengths depending on the stress applied to it is possible.
- the material according to the invention is capable of reflecting different wavelengths according to the applied stress so that, for the same material, a difference in stress implies a different variation in color.
- a first solution consists in modifying the dimensions: length, volume of the piston capsule 43 or hollow 40. These changes in dimensions then lead to a different response to the stress applied by the expansion of the M2 material.
- a second solution consists in using different variants of the material M2, each variant having a different coefficient of expansion.
- This solution makes it possible to have, for capsules 43 or a recess 40 of the same size, variations in different colors since the material M2 will be different.
- a third solution consists in using different materials for the embodiments of the membrane 42. Indeed, by using materials each having different deformation properties, it is ensured that the stress applied to the material M1 will be different and therefore the variation in color will be different. It can also be provided to have, for each piston capsule 43, a specific material M1.
- the recess 40 is used to accommodate a capsule 43 'provided with two half-shells 44' made of flexible material as visible to the Figures 5a and 5b .
- This capsule 43 ′ is then fixed in the recess by gluing or heat welding of one of the half-shells 44 ′.
- This capsule 43 ′ is also arranged to be filled with a material M2 which expands as a function of a physical quantity such as temperature or pressure.
- the recess 40 is closed by a film 42 ′ produced with the material M1. Consequently, when the temperature increases for example, the material M2 in the capsule expands and deforms the half-shell 44 '.
- This half-shell 44 ' exerts a stress in turn on the film 42'. This constraint deforms the film 42 ′ and therefore the material M1 reflects another wavelength. Provision may be made for having several capsules 43 ′ per recess 40 as visible on the figure 5c .
- the covering element 10 is itself used as a capsule 43 ′.
- the covering element will be a strand 31 or a bracelet link 3.
- the bracelet strand is then composed of two strips assembled 310 together. This assembly is carried out so that the two strips 310 are fixed by their periphery so that the interior space 312 can serve as a cavity. This cavity 312 cleverly allows it to accommodate a pocket containing M2 material which expands as a function of a physical quantity such as temperature or pressure.
- one or both bands 310 forming the strand 31 of bracelet 3 carry the material M1 capable of reflecting different wavelengths according to the stress which is applied to it.
- This first material M1 is arranged on one and / or the other of these strips in the form of a film or a strip or by making direct part of the material forming the said strip (s) 310 as visible on the surface. figure 6 .
- the material M1 reacts and expands or contracts, causing a deformation of the band or bands forming the bracelet strand. This deformation is therefore communicated to the first material M1 which, under the effect of this applied stress, sees its structure change and reflect different wavelengths as visible to the figure 7 .
- the bracelet strand 31 comprises stiffening structures 313 as visible on the figure 8 .
- These stiffening structures are arranged between the two strips 310 forming the strand and extend longitudinally or transversely relative to said strand. These structures make it possible to increase the resistance to twisting of the bracelet strand.
- These structures 313 are in the form of at least one wall 314 fixed to the two strips. This configuration allows said walls to delimit different zones 315. For example, by having two transverse walls, three distinct zones are created in the bracelet strand. Cleverly according to this variant, these zones can each be filled with a pocket containing a separate M2 material. This configuration makes it possible to have the band or bands forming the strand which are irregularly deformed, the material M2 of each distinct zone reacting differently.
- the constituent bands of the bracelet strand may be made of different materials. This advantageously makes it possible to have a material having more advantageous deformation characteristics for the strip carrying the first material. This results in that said strip becomes more easily deformable resulting in better reactivity to the expansion of the second material M2.
- the application of the stress to the first material M1 is done by means of a mechanical device 14.
- This mechanical device is arranged to apply, at the request of the user, a stress on the first material and thus modify its dimensions and / or its shape.
- the device 14 allowing the application of a stress on the first material is a pump device 140.
- a pump device 140 is similar to that of the patent US 5,113,599 filed by Reebok®.
- a device schematically consists of a bag 141 made of plastic material provided with a pumping system 142.
- a pumping system 142 comprises a pump 143 and an exhaust valve 144 for inflating and deflating the bag 141 made of plastic material.
- a pump 143 used consists of a hollow bell 143a provided with a hole 143b allowing the air filling of the bell.
- the pump can also be fitted with a non-return valve 145 using a pair of sheets 145a of plastic material which can be welded via a welding point, to a wall of the pump 143. These sheets are folded substantially U-shaped and allow air to pass only in the direction of the arrow from the pump to the pocket.
- an outlet or exhaust valve 144 is used.
- the outlet valve as shown in the figure 9 may include a piston 144a comprising a spring 144b which biases the piston in the closed position.
- a flange 144c around the periphery of the piston rod 144a prevents air from leaking between the piston and the outlet fitting because the flange is biased in the closed position and in contact with said fitting.
- the piston is depressed by the user so that the air escapes around the piston rod.
- This pump system 142 can then be directly arranged at the pocket 141 or be dissociated and be connected to said pocket via a channel.
- the direct arrangement at the pocket 141 or at the channel is achievable by independently manufacturing the pump system 142 on a plastic base. This plastic base will be welded or glued to the pocket or channel, these being provided with an opening as visible on the figure 9 .
- the covering element 1 and the pocket 141 form only one element.
- the covering element 1 is a strand 31 of bracelet 3.
- a strand as described above, comprises two bands 3100 made integral and forming a hollow space 3102 between them. This hollow space 3102 then forms an air pocket.
- One of the two strips 3100 preferably the strip that the user will see while carrying the portable object, will be provided with the pump system 142 as described.
- one of the two strips 3100 preferably the strip which will be visible to the user, will be equipped with an opening 3103.
- This opening 3103 is provided for the installation of the pump system 142.
- This is arranged on a base 142a which will be welded or glued to the strip 3100 of the bracelet strand 31 at the opening 3103.
- the user can act on the pump system 142 to inflate or deflate the bracelet strand.
- the latter is used to carry the first material M1, that is to say the material capable of reflecting different wavelengths according to the stress applied to it.
- This first material M1 is in the form of a more or less thick film deposited on at least one of the two strips 3100 forming the strand 31 of the bracelet, but it can also be provided that the first material M1 forms an integral part of the material. in which the strip or strips 3100 are produced.
- said first material M1 comprises an opal film encapsulated in two films of transparent thermoplastics (TPU type) and the material M1 constitutes at least one of the bands 3100 of the strand.
- TPU type transparent thermoplastics
- the production of the bag and its plastic pump system can be easily carried out by a few heat-sealing operations. Consequently, when the user acts on the pump system 142, he can then increase or decrease the air pressure in the bracelet strand 31. If the pressure increases, the stress exerted by this increase in pressure is transmitted to the bands forming the bracelet strand 31 until it causes a deformation of one and / or the other of the bands 3100.
- the bands 3100 constituting the strand 31 of the bracelet may be made of different materials. It advantageously makes it possible to have a material having more advantageous deformation characteristics for the strip carrying the first material M1. This results in that said strip 3100 becomes more easily deformable resulting in better reactivity to pumping.
- the covering element 10 and the pocket 141 are separated.
- the covering element 10 is a strand 31 of the bracelet.
- Such a strand as described above, comprises two bands 3100 made integral and forming a hollow space 3102 between them.
- the hollow space 3102 between the two strips 3100 is used as housing.
- This housing is used to house a pocket 141 which can be inflated and deflated and provided with an opening 3103 for housing the pump system 142 as described above.
- the principle is therefore that the activation of the pump 145 makes it possible to inflate or deflate the pocket 141 causing its deformation and that of the bands 3100 forming the strand of the bracelet.
- one and / or the other band 3100 forming the bracelet strand carries the first material M1 as described for the first alternative embodiment.
- the inflation or deflation of the bag 141 causes the application or not of a constraint on the bracelet strand which deforms or not.
- the pocket 141 is the element which carries the first material M1.
- This first material M1 is in the form of a film deposited on the pocket but it can also be provided that the first material M1 is an integral part of the material in which the pocket 141 is made.
- at least one of the bands 3100 of the bracelet strand 31 comprises openings 3103. These openings 3103 allow the user to see the pocket 141 reflecting a certain wavelength through the band or bands 3100 forming the bracelet strand 31.
- the pocket 141 inflates under the action of the pump 145, the pocket 141 can be partially inserted into the openings 3103 and therefore deform locally. This local deformation therefore causes a local stress on the first material M1 and therefore a modification of the wavelength that it can reflect.
- the covering element 1, here a bracelet strand 31 consists of a recess 400 and a flexible film 410 made of the material M1 or carrying the material M1.
- the hollow / film assembly constitutes the pocket 141.
- a pump system 142 can then be arranged at the level of the pocket 141 so as to inflate or deflate the pocket 141 and therefore to apply a geometric constraint on the material M1 and therefore to modify its coloring.
- the recess 400, the pump system 142 and the flexible film 410 sealing the pocket are made of thermoplastic. More preferably, the recess 410 is incorporated into a strand 31 of the bracelet obtained by injection.
- the M1 material consists of an opal polymer film encapsulated between 2 sheets of thermoplastics. In this way, the covering element 1 can be obtained by simple assembly operations (ultrasound, heat sealing, or the like).
- the covering element 1 is a watch dial 41, the portable object being a watch comprising a watch movement 25.
- the portable object being a watch comprising a watch movement 25.
- this pocket 141 which can be made from two heat-sealed half-pockets.
- This possibility of using two half-pockets makes it possible to have a pocket 141 produced with different materials such as to have half-pockets with different rigidities in order to have a half-pocket serving as a support and a half-pocket called active which will easily deform.
- This pocket 141 can then be disposed in the housing formed by the dial 41, the middle part 20 and the plate of the watch movement.
- This pocket 141 is then supplied with air via a pumping system 142 placed outside, at the level of the watch case 2 so that it can be handled by the watch wearer.
- a pumping system 142 placed outside, at the level of the watch case 2 so that it can be handled by the watch wearer.
- An ultrasonic bonding or a joint makes it possible to assemble this pumping system to the watch case tightly.
- the pumping system is connected to the bag via a channel 146.
- This channel 146 is an integral part of the bag 141 and is created by the addition of circular welds to reduce the thickness of the inflated area.
- the dial 41 has openings 41a so that the pocket 141 is visible to the wearer of the portable object.
- the part of the pocket visible to the wearer is the part which supports the first material M1.
- the bag inflates or deflates and the material M1 undergoes a stress which makes it change the wavelength of the light it reflects.
- the pocket carrying the material M1 is located in a window or an openwork dial to leave the pocket visible.
- the pocket carrying the M1 material inflates, the opal motif changes color and appears in relief in relation to the rest of the dial.
- the covering element is made of a material which absorbs water. Such a configuration allows the covering element to swell with humidity and therefore causes the appearance of a stress on the first material.

Il est connu des objets portables tels que des montres qui sont équipées d'éléments d'habillage colorés. En général, les éléments d'habillage sont colorés avec une couleur ou un motif particulier et cette coloration est définitive.Portable objects such as watches are known which are equipped with colored covering elements. In general, the covering elements are colored with a particular color or pattern and this coloring is final.
Toutefois, il existe un besoin pour une montre munie d'un élément d'habillage dont la couleur peut varier. Un tel besoin vient de l'envie des consommateurs de pouvoir modifier la couleur de leur montre ou objet portable en fonction des envies ou de l'humeur.However, there is a need for a watch provided with a covering element, the color of which may vary. Such a need comes from the desire of consumers to be able to change the color of their watch or portable object according to their desires or mood.
Une solution évidente consiste à prévoir des accessoires comme des coques de téléphones ou des pièces de rechange pouvant être remplacées facilement par l'utilisateur.An obvious solution is to provide accessories such as phone cases or spare parts which can be easily replaced by the user.
Néanmoins, cette solution présente l'inconvénient qu'il devient nécessaire aux utilisateurs d'avoir une quantité de pièces de rechange en stock, ces pièces peuvent se perdre et il devient nécessaire de renouveler le stock à chaque changement de montre ou téléphone.However, this solution has the disadvantage that it becomes necessary for users to have a quantity of spare parts in stock, these parts can be lost and it becomes necessary to renew the stock with each change of watch or telephone.
Une autre solution consiste à utiliser des pigments dont la couleur peut varier, ces pigments pouvant être photochromiques ou thermochromiques. Ces pigments sont incorporés dans une encre ou directement dans le matériau formant l'élément d'habillage. Un changement de température ou de luminosité est alors suffisant pour modifier la couleur de l'élément d'habillage. Le document
Un inconvénient ici est que cette configuration n'est pas contrôlable.A disadvantage here is that this configuration is not controllable.
En effet, ces pigments réagissent à des valeurs spécifiques de température ou luminosité de sorte que le consommateur n'a que peu d'emprise sur ces éléments, il en est dépendant. On connait par ailleurs du documentIndeed, these pigments react to specific values of temperature or brightness so that the consumer has little control over these elements, he is dependent on them.

La présente invention concerne un élément d'habillage 10 d'un objet portable 1. Ledit objet portable peut être par exemple une pièce d'horlogerie ou montre 1.

Bien entendu, un tel objet portable peut être un téléphone ou un ordinateur ou une tablette électronique tactile ou un bijou comme un bracelet. Il peut aussi être un accessoire de mode, comme un sac ou des lunettes.The present invention relates to a covering
Dans le cas où l'objet portable est une pièce d'horlogerie, la pièce d'horlogerie 1, visible aux
L'élément d'habillage comprend une armature 12 appelée aussi support et réalisée en un matériau métallique ou plastique. Selon l'invention, l'élément d'habillage 10 utilise un premier matériau M1 apte à réfléchir sélectivement différentes longueurs d'ondes visibles selon la contrainte qui lui est appliquée. En effet, il est connu des matériaux capables de créer des couleurs dites structurelles. Ces matériaux sont composés d'au moins deux éléments avec des indices de réfraction différents et alternés de façon périodique. La taille des éléments est de l'ordre de grandeur des longueurs d'onde de la lumière si bien qu'il se crée des phénomènes d'interférence optique (ondes constructives et destructives) qui conduisent à la réflexion sélective de certaines longueurs d'ondes. Les phénomènes d'interférence et donc les couleurs réfléchies dépendent de la taille du réseau périodique et des indices de réfraction des au moins 2 éléments sélectionnés. Dans la nature, il existe, plusieurs exemples de couleurs structurelles. On peut citer : les ailes de papillons, les opales.The covering element comprises a
Ce type de matériaux (dit cristaux photoniques ou matériaux opales) peut également être synthétisé par des techniques connues de l'homme de l'art. Les cristaux photoniques synthétiques sont généralement fabriqués en assemblant de manière ordonnée des sphères mono-dispersées et bi-matières (avec 2 indices de réfraction différents au cœur et à la périphérie).This type of material (known as photonic crystals or opal materials) can also be synthesized by techniques known to those skilled in the art. art. Synthetic photonic crystals are generally produced by orderly assembling mono-dispersed and bi-material spheres (with 2 different refractive indices at the heart and at the periphery).
Le réseau ordonné de sphères peut être réalisé :
- 1) par cristallisation, sédimentation, évaporation d'une suspension colloïdale (la technologie est notamment utilisée dans les encres P-Ink® et Elast-Ink®)
- 2) sous l'effet d'un champ électrique (comme décrit par Baumberg
Advanced Engineering Materials 2013, p 948 - 3) sous l'effet de forces de cisaillement par extrusion (comme décrit par
Baumberg Stretching the imagination, Textiles, issue 4, 2009, 8-10US 2013/0288035
- 1) by crystallization, sedimentation, evaporation of a colloidal suspension (the technology is used in particular in P-Ink® and Elast-Ink® inks)
- 2) under the effect of an electric field (as described by Baumberg
Advanced Engineering Materials 2013, p 948 - 3) under the effect of shear forces by extrusion (as described by
Baumberg Stretching the imagination, Textiles, issue 4, 2009, 8-10US 2013/0288035
Le réseau périodique ainsi formé est ensuite figé par polymérisation UV.The periodic network thus formed is then frozen by UV polymerization.
Un 2ème mode de fabrication des cristaux photoniques consiste à créer des "plots" de taille nanométriques sur film mince flexible (typiquement une feuille de PDMS). Des chercheurs de l'University of California Berkeley ont ainsi fabriqué par des techniques de lithographie des rangées de pixels de silicium qu'ils ont ensuite encapsulés dans 2 feuilles de PDMS (
En effet, lorsqu'un matériau à couleur structurelle est flexible ou déposé sur un support flexible, le réseau périodique peut alors être modifié en jouant sur les dimensions géométriques du matériau et il est alors possible d'obtenir un matériau avec des couleurs structurelles qui changent de façon contrôlée lorsque le matériau est sollicité mécaniquement. Ces dimensions géométriques sont modifiées en appliquant une contrainte sur ledit matériau. Ces contraintes peuvent être un étirement, une compression, une torsion, un pincement ou toutes autres contraintes permettant une modification de la forme et/ou des dimensions du matériau.Indeed, when a material with a structural color is flexible or deposited on a flexible support, the periodic network can then be modified by varying the geometrical dimensions of the material and it is then possible to obtain a material with structural colors which change in a controlled manner when the material is mechanically stressed. These geometric dimensions are modified by applying a constraint on said material. These constraints can be stretching, compression, a twist, a pinch or any other constraints allowing a modification of the shape and / or dimensions of the material.
Ce premier matériau M1 peut alors se présenter sous la forme d'un film plus ou moins épais ou être directement intégré dans le substrat formant l'élément d'habillage 10. Dans le cas d'un film, une première configuration permet au premier matériau M1 de comprendre uniquement un film ou une bande dite opale obtenu par les techniques précédemment décrites. Dans une deuxième configuration, ledit premier matériau M1 comprend le film dit opale assemblé sur un film flexible. Dans une troisième configuration, ledit premier matériau M1 comprend le film opale encapsulé dans deux films flexibles. Les films flexibles étant préférentiellement des films de PDMS ou des films thermoplastiques, préférentiellement des films thermoplastiques polyuréthaneThis first material M1 can then be in the form of a more or less thick film or be directly integrated into the substrate forming the covering
Par conséquent, l'élément d'habillage 10 selon l'invention doit être muni, en plus du support 12, d'un dispositif 14 permettant d'appliquer une contrainte sur le premier matériau M1 pour lui faire changer de couleur.Consequently, the covering
Dans un premier mode de réalisation, l'élément d'habillage 10 est configuré pour que le support 12 et le dispositif 14 permettant d'appliquer une contrainte sur le premier matériau pour lui faire changer de couleur soient un seul et même élément. On comprend alors que le support est apte, de par ses caractéristiques, à être manipuler de sorte à générer une contrainte mécanique sur le premier matériau M1.In a first embodiment, the covering
Selon une forme d'exécution, l'élément d'habillage 10 est un bracelet 30 dit « slap strap » ou « slap band » dans la version anglo-saxonne. Un tel bracelet 30 est composé d'une bande de métal bistable 32 faisant office de support 12. Le bracelet 30 peut être mis à plat en mettant en tension la bande de métal bistable 32 puis enroulé à nouveau autour du poignet en claquant le bracelet. Cette bande de métal bistable 32 peut alors être revêtue d'une couche de protection 34. Cette couche de protection 34 peut être un matériau plastique surmoulé ou un film ou une encre qui se durcit afin d'en améliorer l'esthétisme comme visible à la
Avantageusement selon ce premier mode d'exécution, le premier matériau M1 est agencé sur cette bande de métal bistable.Advantageously according to this first embodiment, the first material M1 is arranged on this bistable metal strip.
Dans une première configuration, le premier matériau est agencé pour recouvrir l'intégralité de la surface du bracelet 30. Le premier matériau M1 peut alors se présenter sous la forme d'un film plus ou moins épais qui peut être collé et/ou cousu et/ou assemblé par collage, soudage ultrasons, soudage laser, soudage infrarouge ou extrudé directement sur la bande métallique bistable 32 comme visible à la
Dans une seconde configuration préférée, pour des raisons de facilité de process, ledit matériau M1 est déposé sur le bracelet 30 puis surmoulé avec un thermoplastique transparent type TPU.In a second preferred configuration, for reasons of ease of process, said material M1 is deposited on the
Dans une troisième configuration préférée, pour des raisons de facilité de process, ledit premier matériau M1 comprend un film opale encapsulé dans 2 films thermoplastiques transparents (type TPU) et le matériau M1 est assemblé au bracelet par des techniques de thermo-soudage.In a third preferred configuration, for reasons of ease of process, said first material M1 comprises an opal film encapsulated in 2 transparent thermoplastic films (TPU type) and the material M1 is assembled to the bracelet by thermal welding techniques.
Dans une autre configuration, le premier matériau M1 est visible à certains endroits spécifiques sur le bracelet. Par exemple, le premier matériau M1 est placé sur la bande métallique bistable (cousu, collé, surmoulé, assemblé ou extrudé) puis une seconde couche 35 (cuir, thermoplastique, ...) ajourée est placée de sorte à laisser ainsi apparaitre le premier matériau M1 comme visible à la
Ainsi, lorsque la bande de métal bistable 32 passe d'un état à un autre c'est-à-dire de l'état dans lequel la bande de métal est sous tension à l'état dans lequel la bande de métal 32 n'est pas sous tension et est enroulée, une variation de contrainte se produit sur la bande de métal. Cette variation de contrainte est transmise au premier matériau M1. Or, le premier matériau M1 est apte à réfléchir différentes longueurs d'ondes selon la contrainte qui lui est appliquée. Par conséquent, lorsque le bracelet slap 30 passe d'un état à un autre, la variation de contrainte permet au premier matériau M1 de réfléchir des longueurs d'ondes différentes et donc d'avoir un bracelet ayant des designs différents selon qu'il est enroulé ou non.Thus, when the
Dans un second mode de réalisation, le support 12 et le dispositif permettant d'appliquer une contrainte 14 sur le premier matériau M1 pour lui faire changer de couleur sont dissociés et l'application de la contrainte au premier matériau se fait par l'intermédiaire d'un matériau M2 apte à voir son volume varier en fonction d'une grandeur physique, cette grandeur physique pouvant être la température. Plus préférentiellement le matériau M2 est un liquide avec une température d'ébullition à pression atmosphérique comprise entre 0 et 60°C. Dans ces conditions, lorsqu'on applique à l'élément d'habillage une température supérieure à la température d'ébullition de M2, le matériau M2 passe en phase gaz et voit ainsi son volume augmenter. Par exemple le matériau M2 est le chlorure d'éthyle, le butane, le propane ou un mélange de ces composés.In a second embodiment, the
Dans un premier mode d'exécution, le support 12 comprend au moins une creusure 40. Cette au moins une creusure 40 est utilisée pour y placer un système de capsule-piston 43 et le matériau M2. Ce système de capsule-piston 43 étanche au matériau M2 est constitué d'une demi-coque 44 et d'un piston 45 comme visible aux
La capsule piston 43 ainsi formée est alors placée dans une creusure 40 de l'élément d'habillage. Cette capsule piston 43 peut être collée, chassée, soudée, vissée ou encore sertie dans la creusure pour y être maintenue. Dans un mode de réalisation préféré, l'élément d'habillage est incorporé à un composant thermoplastique de l'objet portable (par exemple bracelet, cadran, boite de montre,...) et le composant thermoplastique de l'objet portable portant l'élément d'habillage 1 est directement surmoulé sur la capsule piston 43 en formant ainsi la creusure 40. On obtient dans ce cas une très bonne adhésion entre l'élément d'habillage et l'objet portable auquel il est intégré.The
Dans une configuration alternative, ledit premier matériau M1 comprend un film opale encapsulé dans 2 films de thermoplastique transparent (type TPU) et le matériau M1 est assemblé par exemple par thermo-soudage ou par collage.In an alternative configuration, said first material M1 comprises an opal film encapsulated in 2 films of transparent thermoplastic (TPU type) and the material M1 is assembled for example by heat welding or by bonding.
Cette configuration permet avantageusement de réaliser des creusures 40 accueillant chacune une capsule piston 43 comme visible à la
Dans ce mode de réalisation, la variation de coloration du matériau M1 apte à réfléchir différentes longueurs d'ondes selon la contrainte qui lui est appliquée est possible. Effectivement, le matériau selon l'invention est apte à réfléchir différentes longueurs d'ondes selon la contrainte appliquée de sorte que, pour le même matériau, une différence de contrainte implique une variation de couleur différente.In this embodiment, the variation in coloring of the material M1 capable of reflecting different wavelengths depending on the stress applied to it is possible. In fact, the material according to the invention is capable of reflecting different wavelengths according to the applied stress so that, for the same material, a difference in stress implies a different variation in color.
Pour ce faire, une première solution consiste à modifier les dimensions : longueur, volume de la capsule piston 43 ou creusure 40. Ces modifications des dimensions entrainent alors une réponse différente à la contrainte appliquée par la dilatation du matériau M2.To do this, a first solution consists in modifying the dimensions: length, volume of the
Une seconde solution consiste à utiliser différentes variantes du matériau M2, chaque variante ayant un coefficient de dilatation différent. Cette solution permet d'avoir, pour des capsules 43 ou une creusure 40 de même taille, des variations de couleurs différentes puisque le matériau M2 sera différent.A second solution consists in using different variants of the material M2, each variant having a different coefficient of expansion. This solution makes it possible to have, for
Une troisième solution consiste à utiliser des matériaux différents pour les réalisations de la membrane 42. En effet, un utilisant des matériaux ayant chacun des propriétés de déformation différentes, on s'assure que la contrainte appliquée au matériau M1 sera différente et donc la variation de couleur sera différente. Il peut être également prévu d'avoir, pour chaque capsule piston 43, un matériau M1 spécifique.A third solution consists in using different materials for the embodiments of the
Ces possibilités permettent alors de réaliser un élément d'habillage 1 muni d'une multitude de zones utilisant ce premier matériau M1, les différentes zones pouvant avoir des caractéristiques permettant des variations de couleurs différentes.These possibilities then make it possible to produce a
Dans un second mode d'exécution, la creusure 40 est utilisée pour y loger une capsule 43' munie de deux demi-coques 44' en matériau souple comme visible aux
Dans une alternative à ce second mode d'exécution, l'élément d'habillage 10 est lui-même utilisé comme capsule 43'. Dans un exemple non limitatif, l'élément d'habillage sera un brin 31 ou un maillon de bracelet 3.In an alternative to this second embodiment, the covering
Le brin de bracelet est alors composé de deux bandes assemblées 310 ensemble. Cet assemblage est réalisé de sorte que les deux bandes 310 soient fixées par leur périphérie afin que l'espace intérieur 312 puisse servir de cavité. Cette cavité 312 permet astucieusement d'y loger une poche contenant un matériau M2 se dilatant en fonction d'une grandeur physique comme la température ou la pression.The bracelet strand is then composed of two strips assembled 310 together. This assembly is carried out so that the two
Avantageusement selon l'invention, l'une ou les deux bandes 310 formant le brin 31 de bracelet 3 portent le matériau M1 apte à réfléchir différentes longueurs d'ondes selon la contrainte qui lui est appliquée. Ce premier matériau M1 est agencé sur l'une et/ou l'autre de ces bandes sous forme d'un film ou d'une bande ou en faisant directement parti du matériau formant la ou lesdites bandes 310 comme visible à la
Ainsi, lorsque par exemple la température varie, le matériau M1 réagit et se dilate ou se contracte entrainant une déformation de la ou des bandes formant le brin de bracelet. Cette déformation est donc communiquée au premier matériau M1 qui, sous l'effet de cette contrainte appliquée, voit sa structure se modifier et réfléchir des longueurs d'ondes différentes comme visible à la
Dans une variante avantageuse, le brin 31 de bracelet comprend des structures de rigidification 313 comme visible à la
Bien entendu, il pourra être prévu que les bandes constituantes du brin de bracelet soit réalisées dans des matériaux différents. Cela permet avantageusement d'avoir un matériau ayant des caractéristiques de déformation plus avantageuses pour la bande portant le premier matériau. Cela entraine que ladite bande devient plus facilement déformable entrainant une meilleure réactivité à la dilatation du second matériau M2.Of course, provision may be made for the constituent bands of the bracelet strand to be made of different materials. This advantageously makes it possible to have a material having more advantageous deformation characteristics for the strip carrying the first material. This results in that said strip becomes more easily deformable resulting in better reactivity to the expansion of the second material M2.
Dans un troisième mode de réalisation, l'application de la contrainte au premier matériau M1 se fait par l'intermédiaire d'un dispositif 14 mécanique. Ce dispositif mécanique est agencé pour appliquer, à la demande de l'utilisateur, une contrainte sur le premier matériau et ainsi modifier ses dimensions et/ou sa forme.In a third embodiment, the application of the stress to the first material M1 is done by means of a
Pour ce troisième mode de réalisation, le dispositif 14 permettant l'application d'une contrainte sur le premier matériau est un dispositif de pompe 140. Un tel dispositif est similaire à celui du brevet
Pour libérer l'air de la poche, une valve de sortie ou d'échappement 144 est utilisée. La valve de sortie comme représentée sur la
Ce système de pompe 142 peut alors être directement agencé au niveau de la poche 141 ou être dissocié et être connecté à ladite poche via un canal. L'agencement direct au niveau de la poche 141 ou au niveau du canal est réalisable en fabriquant indépendamment le système de pompe 142 sur une base plastique. Cette base plastique sera soudée ou collée sur la poche ou le canal, ceux-ci étant munis d'une ouverture comme visible à la
Dans une première alternative de réalisation visible à la
Dans un exemple non limitatif, l'élément d'habillage 1 est un brin 31 de bracelet 3. Un tel brin, tel que décrit précédemment, comporte deux bandes 3100 rendues solidaires et formant un espace creux 3102 entre elles. Cet espace creux 3102 forme alors une poche d'air. L'une des deux bandes 3100, préférentiellement la bande que l'utilisateur verra en portant l'objet portable, sera munie du système de pompe 142 tel que décrit.In a nonlimiting example, the covering
Pour cela, l'une des deux bandes 3100, préférentiellement la bande qui sera visible par l'utilisateur, sera équipée d'une ouverture 3103. Cette ouverture 3103 est prévue pour la mise en place du système de pompe 142. Celui-ci est agencé sur une base 142a qui sera soudée ou collée sur la bande 3100 du brin 31 de bracelet au niveau de l'ouverture 3103. Ainsi, l'utilisateur pourra agir sur le système de pompe 142 pour gonfler ou dégonfler le brin de bracelet.For this, one of the two
Or, ce dernier est utilisé pour porter le premier matériau M1 c'est-à-dire le matériau apte à réfléchir différentes longueurs d'ondes selon la contrainte qui lui est appliquée. Ce premier matériau M1 se présente sous la forme d'un film plus ou moins épais déposé sur au moins l'une des deux bandes 3100 formant le brin 31 de bracelet mais il peut également être prévu que le premier matériau M1 fasse partie intégrante du matériau dans lequel la ou les bandes 3100 sont réalisées.However, the latter is used to carry the first material M1, that is to say the material capable of reflecting different wavelengths according to the stress applied to it. This first material M1 is in the form of a more or less thick film deposited on at least one of the two
Dans une configuration préférée (non représentée), pour des raisons de facilité de process, ledit premier matériau M1 comprend un film opale encapsulé dans deux films de thermoplastiques transparents (type TPU) et le matériau M1 constitue au moins l'une des bandes 3100 du brin. De cette façon la fabrication de la poche et de son système de pompe en plastique peut être réalisée aisément par quelques opérations de thermosoudage. Par conséquent, lorsque l'utilisateur agit sur le système de pompe 142, il peut alors augmenter ou diminuer la pression de l'air dans le brin 31 de bracelet. Si la pression augmente, la contrainte exercée par cette augmentation de pression se transmet aux bandes formant le brin 31 de bracelet jusqu'à entrainer une déformation de l'une et/ou l'autre des bandes 3100. Cette déformation est transmisse au premier matériau M1 qui voit donc sa structure se modifier entrainant la réflexion d'une longueur d'onde différente. En agissant sur la valve d'échappement 144 du système de pompe 142, l'air est évacuée du brin 31 de bracelet ce qui diminue la pression à l'intérieur de celui-ci. Cela entraine une diminution de la contrainte exercée sur les bandes 3100 qui reprennent alors leur forme initiale. Le premier matériau M1 reprend alors sa structure initiale et réfléchit donc sa longueur d'onde d'origine.In a preferred configuration (not shown), for reasons of ease of process, said first material M1 comprises an opal film encapsulated in two films of transparent thermoplastics (TPU type) and the material M1 constitutes at least one of the
Bien entendu, il pourra être prévu que les bandes 3100 constituantes du brin 31 de bracelet soient réalisées dans des matériaux différents. Cela permet avantageusement d'avoir un matériau ayant des caractéristiques de déformation plus avantageuses pour la bande portant le premier matériau M1. Cela entraine que ladite bande 3100 devient plus facilement déformable entrainant une meilleure réactivité au pompage.Of course, provision may be made for the
Dans une seconde alternative de réalisation visible, l'élément d'habillage 10 et la poche 141 sont dissociés. Dans un exemple non limitatif, l'élément d'habillage 10 est un brin 31 de bracelet. Un tel brin, tel que décrit précédemment, comporte deux bandes 3100 rendues solidaires et formant un espace creux 3102 entre elles.In a second visible alternative embodiment, the covering
Avantageusement selon cette alternative, l'espace creux 3102 entre les deux bandes 3100 est utilisé comme logement. Ce logement est utilisé pour y loger une poche 141 pouvant être gonflée et dégonflée et munie d'une ouverture 3103 pour y loger le système de pompe 142 comme décrit précédemment. Le principe est donc que l'activation de la pompe 145 permet de gonfler ou dégonfler la poche 141 entrainant sa déformation et celle des bandes 3100 formant le brin de bracelet.Advantageously according to this alternative, the
Selon une première solution visible à la

Dans une troisième alternative de réalisation, visible à la
Dans une version préférée de cette alternative pour des raisons de facilité de process, la creusure 400, le système de pompe 142 et le film flexible 410 scellant la poche sont faits en thermoplastique. Plus préférentiellement la creusure 410 est incorporée à un brin 31 du bracelet obtenu par injection. Le matériau M1 est constitué d'un film de polymère opale encapsulé entre 2 feuilles de thermoplastiques. De cette façon, l'élément d'habillage 1 peut être obtenu par des opérations simples d'assemblage (ultrasons, thermosoudage, ou autres).In a preferred version of this alternative for reasons of ease of process, the
Dans un exemple de réalisation visible aux
Cette poche 141 est alors alimentée en air via un système de pompage 142 placé à l'extérieur, au niveau de la boite 2 de montre de façon à pouvoir être manipulées par le porteur de montre. Un collage ultrason ou un joint permet d'assembler ce système de pompage à la boite de montre de façon étanche. Le système de pompage est connecté à la poche via un canal 146. Ce canal 146 fait partie intégrante de la poche 141 et est créé par l'ajout de soudures circulaires pour réduire l'épaisseur de la zone gonflée.This
Le cadran 41 présente des ouvertures 41a de sorte que la poche 141 soit visible par le porteur de l'objet portable. La partie de la poche visible par le porteur est la partie qui supporte le premier matériau M1. Ainsi, lorsque le porteur agit sur le système de pompage, la poche se gonfle ou se dégonfle et le matériau M1 subit une contrainte qui lui fait changer la longueur d'ondes de la lumière qu'il réfléchit.The
Dans une version préférée de l'invention, la poche portant le matériau M1 est située dans un guichet ou un cadran ajouré pour laisser visible la poche. Lorsque la pompe est activée, la poche portant le matériau M1 se gonfle, le motif opale change de couleur et apparait en relief par rapport au reste du cadran.In a preferred version of the invention, the pocket carrying the material M1 is located in a window or an openwork dial to leave the pocket visible. When the pump is activated, the pocket carrying the M1 material inflates, the opal motif changes color and appears in relief in relation to the rest of the dial.
Pour la totalité des modes de réalisation de l'invention, il est possible de modifier la couleur de base et la variation de couleur, en jouant sur la structure même du matériau opale constitutif de M1 lors de sa fabrication. En effet, comme décrit dans la littérature, les indices de réfraction, la taille et l'espacement des composants du matériau opale, permettent de piloter sa couleur d'origine et ses couleurs après sollicitations mécaniques.For all of the embodiments of the invention, it is possible to modify the basic color and the color variation, by playing on the very structure of the opal material constituting M1 during its manufacture. Indeed, as described in the literature, the refractive indices, the size and the spacing of the components of the opal material, make it possible to control its original color and its colors after mechanical stresses.
On comprendra que les modes de réalisation exposés précédemment ne se limitent pas à un bracelet ou cadran mais peuvent aussi être appliqués à un boitier de montre, une carrure, une lunette, une couronne, un poussoir, un fermoir ou une boucle, ou encore une glace.It will be understood that the embodiments described above are not limited to a bracelet or dial but can also be applied to a watch case, a middle part, a bezel, a crown, a pusher, a clasp or a buckle, or even a crystal.
On comprendra que diverses modifications et/ou améliorations et/ou combinaisons évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention exposée ci-dessus sans sortir du cadre de l'invention définie par les revendications annexées.It will be understood that various modifications and / or improvements and / or combinations obvious to a person skilled in the art can be made to the various embodiments of the invention described above without departing from the scope of the invention defined by the appended claims.
Il sera envisageable que, dans le premier mode de réalisation, l'élément d'habillage soit réalisé dans un matériau qui absorbe l'eau. Une telle configuration permet à l'élément d'habillage de gonfler avec l'humidité et donc entraine l'apparition d'une contrainte sur le premier matériau.It will be conceivable that, in the first embodiment, the covering element is made of a material which absorbs water. Such a configuration allows the covering element to swell with humidity and therefore causes the appearance of a stress on the first material.
