    [0001] FIELD OF THE INVENTION [01] The present invention relates to a tire for a motor vehicle comprising a tread and a sidewall, said tire comprising on the tread and / or said side a contrasting marking. with the tread and / or said sidewall.
    [0002] STATE OF THE ART [2] Tires have a large amount of markings intended for example to give technical and legal information, to enable consumers to distinguish the origin of the product. In order to be clearly visible, the markings are in contrast with the tread and / or said sidewall. [3] In addition, the markings are used more and more to give the tire an original appearance. [4] For this purpose, it has become necessary to improve the aesthetics of the markings while maintaining the visibility of the marking with respect to the tread and / or said sidewall. DEFINITIONS [5] "Pneumatic" means all types of elastic bandages subjected to internal pressure or not. [6] "Rubber material" means a diene elastomer, that is to say in known manner an elastomer derived from at least in part (ie homopolymer or copolymer) of diene monomers (monomers carrying two carbon-carbon double bonds, conjugated or not). [7] "Tread" of a tire means a quantity of rubber material delimited by lateral surfaces and by two main surfaces, one of which, called the tread surface, is intended to come into contact with a tire. when the tire is rolling. [8] "sidewall" of a tire means a side surface of the tire disposed between the tread of the tire and a bead of the tire. [09] By "texture" is meant an organized arrangement of a plurality of elements, all or part of the elements of the arrangement being the repetition of the same basic element, for example, a strand or a lamella . [10] "Material texture with tread and / or sidewall" means that the texture is in the same rubber material as the tread and / or the sidewall of the tire. This gives a texture without adding another material. [11] "Strand" means a filamentary element whose height is at least equal to twice the diameter of a disk of the same surface as the average section of the strand. [12] By "lamellae" is meant elongated strands having a length at least twice their height. [13] By "brightness" is meant the parameter that characterizes a surface to reflect more or less light. The brightness is expressed on a scale from 0 to 100 according to the Lab colorimetric model established by the CIE (International Commission on Lighting). The value 100 represents white or total reflection; 0, black 25 or total absorption.
    [0003] SUMMARY OF THE INVENTION [14] The invention relates to a tire made of a rubber material comprising a tread and a sidewall, said tire comprising on the tread and / or said sidewall a marking which contrasts with the tread and or said flank. The marking comprises at least a first zone and a second zone that are in contrast with one another. [15] By defining at least two contrasting zones in the marking with respect to one another, a marking composed of several shades of gray is obtained. This increases the aesthetics of the marking. [16] In a non-limiting embodiment, the first zone comprises a brightness, called the first brightness, which is between 0 and 15. [17] This makes it possible to approach a certain level of black. [18] In a nonlimiting embodiment, the tread and / or said sidewall comprises a brightness, called third brightness, and the second zone comprises a brightness, called second brightness, which is greater than said first brightness and less than said third brightness. [19] This makes it possible to obtain a second zone which is in contrast with the first zone, but also with respect to the tread and / or said sidewall. This allows to get closer to a certain level of gray. [20] In a nonlimiting embodiment, the tread and / or said flank 25 comprises a brightness, called third brightness, which is greater than or equal to 18. [21] This makes it possible to approach a certain level of white and therefore to obtain a better contrast with the marking. [22] In a nonlimiting variant embodiment, said third brightness is greater than or equal to 20. [23] In a non-limiting embodiment, the first zone and the second zone each comprise a particular texture that contrasts with the rolling strip and / or said sidewall. [24] This allows to obtain drawings, logos, graphics, etc. ..., having several shades of gray, and thus improve the visual quality of the desired representations. The proposed textures also have the particularity of having a certain "stability" of the gray level according to the lighting direction (at constant power), therefore of keeping the hierarchy of gray level classes when the source or sources of The lighting varies in spatial position, for angles to the normal to the surface of up to 450. [25] In a non-limiting embodiment, the texture comprises a plurality of protruding or recessed elements with respect to the tread and / or said sidewall. [26] This makes it possible to obtain a texture of the "velvet" type, whether at the level of the touch or at the visual level. [27] In one nonlimiting embodiment, all or part of the protruding elements are strands distributed in the texture at a density of at least one strand per square millimeter (mm 2), each strand having a mean cross-section between 0.0005 mm2 and 1 mm2. [28] In a non-limiting embodiment, all or part of the protruding elements are lamellae substantially parallel to each other, the pitch of the lamellae in the texture being at most equal to 0.5 mm, each lamella having an average width. between 0.02 mm and 0.25 mm. [29] In one nonlimiting embodiment, all or part of the protruding elements form side parallelepipeds between 0.05 mm and 0.5 mm, with a height of between 0.05 mm and 0.5 mm, the distance between two adjacent parallelepipeds in the texture being between 0.05 mm and 0.5 mm. [30] In a non-limiting embodiment, the protruding elements 5 have shapes and distances between variable protruding elements in the texture. [31] This makes it possible to create randomness in the texture, which makes these elements less visible. [32] In a non-limiting embodiment, the first recessed elements form openings on the tread and / or the sidewall, and the texture comprises a plurality of openings, these openings being distributed in the texture according to a density at least equal to one opening per square millimeter (mm 2), these openings having equivalent diameters of between 0.01 mm and 1.2 mm. [33] This makes it possible to obtain a "velvet" type texture at the visual level. [34] In a non-limiting embodiment, the texture of the first zone has different elements of the texture of the second zone. [35] This makes it possible, by differentiating the type, shape, size or pitch of the two textures, to obtain two different gray levels with the visual advantages mentioned above. This also allows for graphical representations having at least 2 gray levels, having a stability in the hierarchy of gray levels when the light source varies in a reasonable way, as well as the direction of observation (especially for solid angles relative to the vertical between 0 and 450, whether for the light source or for the direction of measurement or ob- servation). [36] In a non-limiting embodiment, the texture of the first zone differs from the texture of the second zone according to one of the following parameters: - a density of elements in the texture; - a width of the elements in the texture; - a height of the elements in the texture; - a depth of the elements in the texture. [37] This allows to obtain two different gray levels with the visual advantages mentioned above.

In the following description, elements that are substantially identical or similar will be designated by identical references. [40] In FIGS. 1 to 3 is shown a part of the tire 1 comprising a tread 2 and a sidewall 3, said tire 1 comprising on the tread 2 and / or said sidewall 3 a marking 4 in contrast with tread 2 and / or said sidewall 3. [41] In nonlimiting examples, marking 4 comprises technical and legal information, a graphic element intended to distinguish the origin of the product, or an image. [42] Figure 1 shows a portion of the tire 1 having a tread 2 and a sidewall 3 according to a first non-limiting embodiment. According to this embodiment, the sidewall 3 has a marking 4. [43] FIG. part of the tire 1 comprising a tread 2 and a sidewall 3 according to a second non-limiting embodiment In this embodiment, the tread 2 has a marking 4 which is a graphic element. [44] FIG. 3 represents a part of the tire 1 comprising a tread 2 and a sidewall 3 according to a third nonlimiting embodiment. According to this embodiment, the tread 2 comprises a first marking 4 which is a graphic element and the flank 3 comprises a second marking 4 which is an image. In the example taken, the image represents four nested stars in relation to each other. [45] According to FIGS. 1 and 2, the marking 4 contrasts respectively with the sidewall 3 and the tread 2, and it comprises a first zone 41 and a second zone 42 which are in contrast with one another with respect to the other. [46] According to FIG. 3, the markings 4 contrast with the tread 2 and the sidewall 3, the first marking 4 on the tread 2 which is a graphic element comprises a first zone 41 and a second zone 42 which are in contrast to each other, and the second marking 4 on the image-forming sidewall 3 has a plurality of areas 41, 42, 43, 44 which are in contrast to one another. [47] In other words, an area is in contrast with each area adjacent to it. Thus, in the nonlimiting example of FIG. 3, the second marking 4 comprises: a first zone 41 (which has a black appearance) which is in contrast with: a second adjacent zone 42 (which has a gray appearance dark); a third zone 43 adjacent (which has a light gray appearance); the second zone 42 which is in contrast with a fourth adjacent zone 44 (which has a lighter gray appearance). [48] Thus, by multiplying the areas that are in contrast to one another, gray gradients are obtained which give different levels of contrast. It is thus possible to play on the different gradations of gray to give a more aesthetic appearance to the marking 4 of the tire 1. [49] In a non-limiting embodiment, the first zone 41 comprises a brightness L * 1, called the first brightness, which is between 0 and 15. [50] By characterizing the brightness of the first zone 41, a zone of black appearance is obtained which is in contrast with the tread 2 in the case of FIG. 3 to the flank 3 in the case of FIG. 2 or with respect to both in the case of FIG. 3. [51] Furthermore, the second zone 42 comprises a luminosity L * 2, called the second brightness, which is greater than the first brightness L * 1 and less than the brightness L * p, said third brightness of the sidewall in the example of Figure 3. [52] In this way, by characterizing the brightness of at least two areas 41 and 42, gets a mark 4 that absorbs enough light and that is It is sufficiently contrasted with the tread 2 and / or said sidewall 3. On the other hand, this makes it possible to carry out gradations of gray ranging from light gray to black, so as to bring out a good area relative to each other. [53] Thus, in the non-limiting examples of FIGS. 1 and 2, the first zone 41 has a brightness L * 1 which gives it a black appearance, while the second zone 42 has a luminosity L * 2 which gives it an appearance. Grey. [54] In the case where the marking 4 is an image which has a plurality of areas 41, 42, 43, 44, etc., having contrasts between different areas of the image makes it possible to highlight the different details of this image. In the non-limiting example of Figure 3, we distinguish the different stars. This allows an image to be more realistic. [55] Thus, in the nonlimiting example of FIG. 3: the first zone 41 has a brightness L * 1 which gives it a black appearance; the second zone 42 adjacent to the first zone 41 has a brightness L * 2 greater than L * 1 which gives it a dark gray appearance; the third zone 43 adjacent to the first zone 41 has a brightness L * 2 'greater than L * 1 and L * 2 which gives it a light gray appearance; the fourth zone 44 adjacent to the second zone 42 has a brightness L * 2 "greater than L * 1 and L * 2 which gives it a lighter gray appearance In the example taken, L * 2" is equal to L * 2. [56] The contrast is even more marked between the different zones 41, 42, 43, 44 and the flank 3 that said flank 3 comprises a third brightness L * p greater than or equal to 18. In a non-limiting embodiment variant the third brightness L * p is greater than or equal to 20. [57] It will be noted that the values between 15 and 18 are representative of certain gray levels. Thus, by adjusting the brightness of the second zone 42, the third zone 43, the fourth zone 44 in this range of values, it is possible to obtain different levels of gray which will be in contrast with the black level of the first zone 41 and the white level of the sidewall 3 in the example taken. [58] Note that when the sidewall 3 is smooth, tests carried out by the inventive entity have shown that the sidewall 3 generally has a luminosity of between 23 and 25. Similarly, when the sidewall 3 has grooves (which give an aesthetic aspect to the flank), tests carried out by the inventive entity have shown that the flank 3 has a luminosity substantially equal to 20. [59] In a non-limiting embodiment, the first zone 41 and the second zone 42 each has a particular texture 5, 5 'contrasting with respect to the tread and / or said sidewall. Thus, when the marking 4 comprises more than two zones, as in the example of FIG. 3, all the different zones 41, 42, 43, 44 of the marking 4 each comprise a particular texture that contrasts with respect to the sidewall 3. [60] The texture is made of rubber material. In a non-limiting embodiment, the texture is integral with the tread and / or said sidewall (for example the strands or slats described below are made of rubber material integrally with the tire). [61] In a first nonlimiting embodiment, the texture 5 of the first zone 41 comprises elements different from the texture 5 'of the second zone 42. Thus, when the marking 4 comprises more than two zones, as in FIG. In the example of Figure 3, at least two areas have textures with different elements. [62] In a second nonlimiting embodiment, the texture 5 of the first zone 41 has the same elements as the texture 5 'of the second zone 42. [63] Thus, when the marking 4 comprises more than two zones, as in the example of Figure 3, at least two zones have textures with identical elements. [64] The textures 5 and 5 'are described below according to various non-limiting embodiments. [65] According to a first non-limiting embodiment, the texture 5, 5 'comprises a plurality of protuberance elements with respect to the tread and / or said sidewall, and more particularly with respect to the surface where it is located. said marking 4, namely the surface 30 of the sidewall 3 in the case illustrated in FIG. 1 or the tread surface 20 of the tread 2 in the case illustrated in FIG. 2 or the surface 30 of the sidewall 3 and the surface Tread 20 of the tread 2 in the case illustrated in FIG. 3. [66] The effect of these protruding elements is to "trap" a large quantity of incident light rays that meet the texture 5, 5 '. In this first embodiment, the texture 5, 5 '(called "velvet") makes it possible, on the one hand, to obtain a "velvet" type of visual because the protruding elements absorb the light and thus make the marking more black, and secondly, a touch of "velvet" type, said protruding elements providing a pleasant marking to the touch. [67] Figure 4 illustrates the texture 5, 5 'according to a first non-limiting embodiment of the first embodiment. In this variant, all or part of the protruding elements are strands 6 distributed in the texture 5, 5 'in a density at least equal to one strand per square millimeter (mm 2), each strand having an average section S of between 0, 0005 mm2 and 1 mm2. It should be noted that the average section of each strand corresponds to the average of sections S measured at regular intervals from the base of the strand. The strands 6 have a generally conical shape with a decreasing section in the Hb height of these strands. [68] Figure 5 illustrates the texture 5, 5 'according to a second non-limiting embodiment of the first embodiment. In this variant, all or part of the protruding elements 5 are slats 7 substantially parallel to each other, the pitch P of the slats in the texture being between 0.1 mm and 0.5 mm, each slat 7 having an average width of between 0.02 mm and 0.25 mm. It should be noted that the average width corresponds to the average of the widths 1 measured at regular intervals in the height H1 of the lamella, the height of each lamella being between 0.05 and 0.5 mm. [69] In another embodiment, the texture comprises a combination of strands 6 and slats 7. [70] Figure 6 illustrates the texture 5, 5 'according to a third non-limiting embodiment of the first embodiment. In this variant, all or part of the protruding elements form parallelepipeds 8 with a side C of between 0.05 mm and 0.5 mm, with a height Hp of between 0.05 mm and 0.5 mm, the distance Dp between two adjacent parallelepipeds 8 in the texture being between 0.05 mm and 0.5 mm. [71] In another alternative embodiment, the texture comprises a combination of the raised elements 6, 7 and 8, or 6 and 8, or 7 and 8 described above. [72] Figure 7 illustrates the texture 5, 5 'according to a fourth non-limiting embodiment of the first embodiment. In this variant, the protuberance elements 9 present in the texture 5, 5 'shapes and distances between elements protruding variable. This variant makes it possible to make the protruding elements on the texture 5, 5 'less visible. [73] Thus, when the texture of the first zone 41 has the same elements as the texture 5 'of the second zone 42, the two textures 5 and 5' differ according to at least one of the parameters selected from the following: a density of elements 6, 7, 8, 9, 10, 11 in the texture 5, 5 '. a width of the elements in the texture 5, 5 '. This applies in particular for the elements in the form of slats 7 previously seen. a height of the elements in the texture 5, 5 '. This applies in particular for the parallelepiped-shaped elements 8 previously seen. - a depth of the elements in the texture 5, 5 '. This applies in particular for the cavity-shaped elements 12 previously seen. [74] The differentiation according to at least one of these parameters makes it possible to characterize the first brightness L * 1 and the second brightness L * 2 and thus to implement the contrast between the first zone 41 and the second zone 42 [75] a second non-limiting embodiment, the texture 5, 5 'comprises a plurality of hollow elements 10 (also called holes) with respect to the tread 2 and / or to said flank 3, and more particularly with respect to the surface where is said texture 5, 5 ', namely the surface 30 of the sidewall 3 in the case illustrated in Figure 1 or the tread surface 20 of the tread 2 in the case illustrated in Figure 2 or the surface 30 of the sidewall 3 and the tread surface 20 of the tread 2 in the case illustrated in FIG. 3. The recessed elements 10 are composed of openings 11 on the tread and / or on said sidewall and cavities 12 associated extending in the depth of the surface 20 and / or 30. [76] Thus, the texture 5, 5 'comprises a plurality of openings 11 on the tread and / or the sidewall, said openings 11 being distributed in the texture 5, 5' according to a density at least equal to one opening per square millimeter (mm 2) and having on the surface equivalent diameters Dt of between 0.01 mm and 1.2 mm. [77] The openings 11 extend into the depth of the surface 20 and / or 30 to form cavities 12. [78] The effect of these cavities 12 is to "trap" a large amount of incident light rays that meet the texture 5, 5 ', but also to offer a greater durability of the texture 5, 5'. Indeed, as the cavities 12 are recessed in the surface, the impact of mechanical stresses on the texture, such as friction of a roadway is lower than for protuberances. In this second embodiment, the texture 5, 5 '(called "velvet") provides a visual type "velvet" because the cavities absorb light and thus make the marking darker. [79] In a non-limiting embodiment, all or part of the cavities 12 has a depth of at least 0.1mm. In a non-limiting embodiment variant, all or part of the cavities 12 has a depth of between 0.2 mm and 0.6 mm. In this way, it is ensured that a large quantity of incident light rays which encounters the texture 5, 5 'is trapped by said texture and, since the depth of the cavities is limited, it is also possible to degrade the mechanical strength of surface 20 and / or 30. [80] FIG. 8 illustrates the texture 5, 5 'according to a non-limiting variant of this second embodiment. In this variant, all or part of the cavities 12 are in the form of cones which extend in the depth of the surface 20 and / or 30 and open out onto the surface forming circular openings 11. The cavities 12 thus have a section which decreases in the depth of the surface. In this way, the contrast of the texture 5, 5 'is improved with respect to the tread 2 and / or to the side 3. Note that in this variant, the openings 11 of the cavities 12 do not touch each other. The openings 11 are separated by intermediate zones 13. In addition, the openings 11 are evenly distributed over all or part of the 20/30 surface delimited by the marking 4 so that the distance d between each opening of the texture is globally similar. . [81] FIG. 9 is a zoom on a cavity 12 of a hollow element 10 of the texture of FIG. 8. In a nonlimiting embodiment, all or part of the cavities has at least one wall 14 which, according to FIG. a sectional view forms an angle p between 100 and 60 ° with respect to a direction Z perpendicular to the texture 5, 5 '. [82] Whenever a light ray encounters a wall 14 of the cavity 12, the latter is reflected by said wall 14. The direction of reflection of the light beam depends on the initial direction of this light beam and the angle of inclination of the wall 14. Thus, depending on this initial direction and this angle of inclination, the light beam can be returned to another wall 14 of the cavity. Conversely, the light ray can be returned outside the cavity, for example directly to an observer. In the first case, the light ray "gets lost" in the cavity and it will no longer be perceptible by the eye of an observer. In the second case, the observer can perceive the light ray and the texture may then appear to be lighter and therefore less in contrast with respect to the tread and / or said sidewall. By choosing a cavity 12 having at least one wall 14 which forms an angle p between 100 and 60 °, it is ensured that a large part of the light rays entering the cavity 12 will be absorbed by this cavity under the effect of multiple reflections inside the cavity. In this way, the contrast of the texture 5, 5 'is improved with respect to the tread and / or said sidewall, while maintaining the same cavity occupancy rate in the texture. In addition, with this inclination of the wall, the resistance of the texture is generally improved, especially during repeated rubbing with the roadway. [83] The invention is not limited to the examples described and shown and various modifications can be made without departing from its scope. [84] Thus, according to another non-limiting embodiment, the slats 7 of Figure 5 may be discontinuous. They have a flat part between them. In addition, they may have section differences between them. In addition, the slats may have curvatures or angles, especially in their length. They can also be of variable length. [85] Thus, according to another variant of non-limiting embodiment, the openings 11 of FIG. 8 can have the shape circular, square, or else polygonal (for example hexagonal) and the cavities 12 corresponding a shape of cylinders, parallelepipeds , or even polygons. With these two last structures (square or polygonal), it is possible to more easily organize the openings 11 relative to each other so as to limit the area of the intermediate zones 13 between these openings. With such forms of openings, it is possible to arrive more easily at substantial rates of occupancy of the openings. [86] Thus, the described invention has the following advantages in particular: by characterizing the brightness of the different zones of the marking, gradations of gray and black are obtained which allow the details of a marking to be highlighted; ; by characterizing the brightness of the different areas of the marking, contrasts are obtained within a marking; it makes it possible to increase the aesthetic level of a marking compared to a solution that would only use contrast in "black" and "white" only.
