Definitions

  • the invention concerns a device for articulating two watch components. It also relates to a timepiece as such comprising at least one such articulation device.
  • a watch case has two pairs of horns, each pair of horns delimiting a housing for receiving a link arranged at the end of a bracelet strand.
  • An axis extending between the two horns of a pair of horns engages this link of the bracelet strand, holding it in position between these two horns, while allowing the relative articulation of the bracelet strand and the case watch, by pivoting around this axis.
  • the present invention aims to improve the situation.
  • the general object of the invention is therefore to define an improved solution for the articulated assembly of two watch components.
  • an object of the invention is to define a reliable and robust solution for the respective articulation of two watch components.
  • the invention is based on a device for articulating two watch components, comprising at least one articulation axis, a first and a second watch components linked together in an articulated manner via the at least an articulation axis, characterized in that said two watch components each respectively comprise a first and a second guide surface which cooperate with respectively a first and a second articulation surface of at least one articulation portion of the at least one articulation axis, said guide surfaces and said respective articulation surfaces being positioned opposite each other for guiding by friction the rotational movement of respectively the two watch components relative to said at least one axis of articulation articulation, in that the at least one articulation portion of the articulation axis or the at least one articulation axis is made entirely of ceramic, and in that the at least one articulation axis comprises at least one portion of less resistance positioned out of reach of said guide surfaces respectively of said two watch components, and characterized in that the at least one articulation portion of the articulation
  • THE figures 1 to 5 illustrate a first embodiment of an articulation device of the invention, comprising a connecting element 11 arranged at the end of a bracelet strand 10, a receiving element 21 which is in the form of two substantially parallel horns and arranged opposite each other on a middle part 20, and two hinge pins 1 intended to fix in an articulated manner the connecting element 11 and the receiving element 21, that is to say a strand of bracelet 10 on a caseband 20.
  • the connecting element 11 is in the form of a bracelet link, forming a connecting link.
  • This connecting link is intended to be arranged at the end of a bracelet strand 10. It advantageously has the same shape and appearance as the other bracelet links.
  • each horn of the receiving element 21 of the middle part 20 comprises a bore 21a, which appears in particular as a blind hole.
  • the two bores 21a of respectively the two horns are arranged along axes which are preferably substantially aligned.
  • the bores 21a have a circular cross section.
  • the openings of the two bores face each other.
  • the space between the two horns defines a housing intended to be occupied by the connecting link of the bracelet.
  • the visible exterior surface of the horns presents no modification, no discontinuity, which would degrade its appearance.
  • the two bores could have through holes and/or be provided with bearing surfaces and/or have non-parallel orientations between them.
  • the articulation device further comprises two articulation axes 1 intended to fix or not between them, in an articulated manner, the connecting element 11 and the receiving element 21.
  • fixing must be understood by the fact that the two watch components considered cannot be separated from each other when they are fixed. However, they retain at least one degree of freedom in rotation relative to each other, via at least one hinge axis, which makes them an articulated fixation.
  • Each hinge pin 1 can occupy two positions, a position projecting from the connecting element 11, as shown in the figure 2 , and a recessed position within a housing 11a of the connecting element 11, as represented by the Figure 3 , as will be clarified later.
  • Each articulation axis 1 is positioned within a housing 11a arranged in the connecting element 11.
  • Two housings 11a extend preferentially along the same axis A1.
  • the housings 11a are in the form of a transverse and through hole.
  • this hole opens out from the two opposite side walls or sides 11b of the connecting element.
  • Each housing 11a allows a hinge pin 1 to slide freely along the axis A1, according to a degree of freedom in translation. This degree of freedom in translation makes it possible to position the hinge pins 1 projecting or recessing the flanks 11b of the connecting element 11, so as to respectively allow the assembly and disassembly of the connecting element 11.
  • each of the housings 11a could be in the form of a blind hole opening onto the sides 11b and/or be provided with bearing surfaces.
  • the connecting element 11 further comprises a recess 2a, particularly visible on the Figure 3 , extending from a wall of the connecting element 11 and opening out at at least part of the housings 11a of the hinge pins, so that the hinge pins 1 can be manipulated by an operator at the level of this recess 2a.
  • An added element 2 which is in the form of a cover in this embodiment, is intended to take place within the recess 2a. When positioned in this recess, the added element 2 cooperates with the hinge pins 1, as will be described subsequently.
  • the connecting element 11 comprises a tapping 4a.
  • the added element 2 is removable.
  • the added element 2 advantageously has a shape complementary to that of the recess 2a, in particular a volume corresponding or substantially corresponding to that of the recess 2a, so that, when it is fixed on the element of connection 11, its visible surface matches the neighboring surface of the connecting element 11 and/or the receiving element 21 to form a substantially continuous surface.
  • the attached element 2 can conform to the articulation device and optimizes the aesthetic appearance of the connecting element 11 and/or the receiving element 21.
  • the attached element 2 is , preferably, arranged on the non-visible side of the connecting element 11. For example, it is provided on the face of the connecting mesh intended to come into contact with the wearer's wrist.
  • the added element may have another shape, and may in particular project from the connecting element 11 and/or the receiving element 21.
  • it can be fixed to the connecting element by any other means, such as driving, gluing, clipping, welding, soldering, etc. It is therefore not necessarily removable, in which case the bracelet strand would not be removable once attached to a caseband.
  • the added element can be in several parts and/or arranged within the element of reception 21. Consequently, the recess 2a can also be in several parts and/or arranged within the reception element 21 at the level of at least one part of housings 21a of the articulation axes.
  • the means for fixing the added element(s) are adapted and/or rearranged accordingly within the receiving element.
  • each hinge pin 1 has an identical shape and is arranged symmetrically in the connecting element 11.
  • This connecting element 11 has a substantially symmetrical shape relative to a median plane perpendicular to the axis A1.
  • the articulation device comprises at least one articulation axis 1 entirely made of ceramic, or entirely based on ceramic, that is to say comprising at least 50% by weight of ceramic, or even at least 75% by weight, or even at least 90% by weight.
  • the articulation axis or at least its articulation portion(s) is completely made of ceramic, or totally based on ceramic, that is to say that the same material occupies the entire volume of the articulation portion(s) of the articulation axis 1, or even occupies the entire volume of the articulation axis 1, or substantially the entire volume.
  • the two hinge pins 1 of the embodiment are identical.
  • a technical ceramic and preferably a sintered technical ceramic, to form all or part of the articulation axis, as explained above.
  • the adjective “technical” refers to the high performance properties of the chosen ceramics. Indeed, technical ceramics can achieve very high mechanical, thermal, even electrical, and/or biochemical properties, as well as chemical inertia and non-magnetism, which make them suitable for use to form a joint axis.
  • the technical ceramics used here differ from traditional ceramics by their composition, since they are derived from purified synthetic powders and not from natural mineral powders such as feldspar or kaolin.
  • zirconia-based ceramics are advantageously used because they have high mechanical properties.
  • the ceramic is a yttriated zirconia of type 2Y or 3Y, namely comprising respectively a yttrin content of 2% and 3% molar.
  • the ceramic used for the articulation axis is advantageously a “dense” ceramic, that is to say a ceramic whose density is between 95% and 100 % of the theoretical density of the ceramic material considered.
  • the material of the hinge pin can be chosen so that the hinge pin, or at least its hinge portion(s), has a hardness greater than 800 HV.
  • the articulation axis, or at least its articulation portion(s) can be completely made of ceramic, that is to say entirely composed of ceramic. Alternatively, it can be entirely based on ceramic, that is to say entirely in a material comprising at least 50% by weight of ceramic, supplemented by another material such as for example a metal or a metal alloy, thus forming a composite material.
  • the articulation axis, or at least its articulation portion(s), is advantageously presented in a single piece form, entirely in the material defined above.
  • each hinge pin 1 has a continuous and cylindrical hinge portion, which extends from a first external end of the hinge pin.
  • This articulation portion defines a first articulation surface 1a, intended to cooperate with the receiving element 21, and a second articulation surface 1e, intended to cooperate with the connecting element 11.
  • the receiving element 21 comprises a first guide surface formed by the peripheral surface of the bore 21a, intended to cooperate with the first articulation surface 1a of the articulation axis 1.
  • the receiving element connection 11 comprises a second guide surface formed by the peripheral surface of the housing 11a, intended to cooperate with the second articulation surface 1e of the articulation axis 1. Said guide surfaces and said respective articulation surfaces are positioned facing each other for guiding by friction the rotational movement of respectively the receiving element 21 and the connecting element 11 relative to said articulation axis 1.
  • Each articulation axis 1 also has a portion of less resistance positioned outside said articulation portion, and in particular out of reach of said guide surfaces 1a, 1e. This portion of less resistance is arranged at the level of the second internal end of the articulation axis, opposite the end towards which the first articulation surface 1a is arranged. It forms a functional portion of articulation axis 1.
  • this functional portion arranged at this second internal end of each hinge pin 1, forms a stop surface 1b.
  • the added element 2 comprises at least a first surface which defines an axial stop 2b, intended to cooperate with this stop surface 1b of each articulation axis 1, in order to maintain it in a position projecting from the sides 11b of the element connecting element 11, when the attached element 2 is fixed on the connecting element 11.
  • its stops 2b come into contact with the abutment surface 1b of each respective articulation pin 1, in a projecting position, thus preventing the articulation pins 1 from moving back from the flanks 11b of the connecting element 11, so that the articulation pins 1 remain protruding.
  • Reported item 2 also includes a recess 2c on the periphery of the hinge pin 1 and out of reach of the latter.
  • the hinge pin 1 includes a portion of less resistance, due to the presence of a groove 1f.
  • This groove allows in particular the translation of the articulation axis into the withdrawal position using a tool, such as a dowel or tweezers.
  • the bottom of the groove 1f is provided with roundings or fillets, in order to limit stress concentrations as much as possible.
  • the groove 1f is separated from the abutment surface 1b by a part 1g of frustoconical shape relative to the axis A1, having a maximum diameter less than the diameter of the housing 11a in which the articulation axis is positioned.
  • the geometry of this portion of lower resistance is thus shaped so that it can never come into contact with the housing 11a and the recess 2c of the added element 2, as is visible on the figures 2 to 4 , even when the joint axis 1 is biased, which would be induced by functional play.
  • the clearance between the at least one portion of lower resistance and the recess 2a, 2c is greater than the clearance between the guide surfaces and the articulation surfaces.
  • This articulation axis 1 is notably represented by the Figure 5 .
  • the housing 11a and the recess 2c can have a clearance around the portion of least resistance of the hinge pin 1, so that the latter is out of reach of any contact with the neighboring walls during relative rotations.
  • FIG. 4 illustrates such an alternative embodiment in which the recess 2a of the connecting element 11 and the recess 2c of the cover are enlarged to create a clearance or clearance around the portion of less resistance of the hinge pin 1
  • the aforementioned frustoconical shape of the portion of lower resistance is no longer essential and can be replaced by another shape, in particular cylindrical.
  • the functional portion of the hinge pin 1, which here comprises one or more portions of less resistance is advantageously out of reach of the portion(s). articulation and cannot be used when wearing the watch.
  • the optional frustoconical shape of part 1g also makes it easier to insert a tool into the groove 1f for moving the hinge pin towards the recessed position.
  • the width of the groove 1f of the hinge pin 1 is of the order of 0.3 mm, measured in the longitudinal direction of the hinge pin, with an internal diameter of approximately 0.85 mm.
  • the radius of the roundings at the bottom of the groove is approximately 0.15 mm, or approximately half of said width.
  • the diameter of the articulation portion is of the order of 1.3 mm and its length is of the order of 3.6 mm.
  • the total length of the hinge pin is around 4.5 mm.
  • each articulation axis 1 has two degrees of freedom relative to the connecting element 11: a translation along the axis A1 and a rotation on itself along this same axis A1. Fixing the added element 2, when the hinge pins 1 are in their position projecting from the connecting element 11, makes it possible to eliminate the degree of freedom in translation, the hinge pins 1 then remaining blocked in their protruding position. These articulation axes 1 retain their degree of freedom in rotation.
  • each hinge pin 1 preferably comprises a groove 1f at its functional portion, as mentioned previously, which allows the insertion of a simple tool, such as a dowel or tweezers, to manually guide the backward translation of the two articulation axes.
  • a simple tool such as a dowel or tweezers
  • any other means or tool allowing the two articulation axes to be actuated can be considered.
  • the middle part including its horns, and therefore the receiving element 21 and/or the connecting element 11 is made of metal, in particular of precious metal, such as gold or platinum, to be able to obtain a desired aesthetic result.
  • an attached element 2 can take different shapes.
  • an attached element could be provided on a receiving element, to cooperate with a hinge pin at the level of the receiving element. This cooperation may consist of blocking the degree of freedom of said articulation axis in translation, to maintain it in the projecting position.
  • the same or several attached elements could cooperate with both the connecting element and/or the receiving element. For example, an added element can thus be fixed on each of the horns of the middle part 20.
  • the receiving element arranged on the middle part could not be in the form of two horns, but for example in the form of a single horn.
  • the connecting element 11 arranged at the end of the bracelet strand could be presented in two complementary and distinct lateral elements, each integrating a hinge pin 1, these two hinge pins 1 being intended to come on either side of the simple horn for attaching the bracelet strand to a caseband.
  • An attached element is then arranged on the receiving element in the form of a simple horn, and each lateral element of the connecting element comprises a projecting hinge pin extending into a bore of the simple horn. The added element blocks these hinge pins in their projecting position.
  • the middle can therefore include at least one horn, in particular one or two horns. Any other middle architecture is possible, in particular comprising an element of the articulation device of the invention which is not necessarily in the form of one or more horns.
  • the connecting element is arranged at the end of a bracelet strand.
  • the connecting element comprises an assembly of links, in particular metal links
  • the connecting element is advantageously in the form of a connecting link which comprises a shape identical or similar to other links of the bracelet strand, to give a continuous aesthetic result.
  • the bracelet strand can be made of flexible material, for example leather.
  • the connecting element can be integrated into the end of the flexible bracelet strand, preferably in a totally or partially concealed manner. Alternatively, it may appear as a metal end arranged at the end of the flexible bracelet strand.
  • the connecting element is arranged on a watch case, in particular on a middle part, and the receiving element is arranged on a bracelet strand.
  • the construction of the articulation device described previously could be reversed. That is to say, the receiving element 21 could be a bracelet link and the connecting element 11 could be one or more horns of a middle part.
  • the added element may comprise a means for acting on a hinge pin during its positioning in a recess and/or during its removal from the connecting element and/or the receiving element, so as to drive said articulation axis in translation, to automatically move it from its position of withdrawal to its protruding position and/or vice versa.
  • one embodiment compatible with all the embodiments described, is based on an articulation device in which the attached element is removable.
  • the added element is advantageously removed from the articulation device when the latter is in its first configuration. It is fixed on this articulation device in the second configuration.
  • the invention is not, however, limited to an articulation device equipped with an attached element as described.
  • the articulation device could comprise only one configuration, or be actuated by any means other than via an attached element as described.
  • the invention is not limited to the embodiment described and its variants.
  • the embodiment described above and its variants can thus be reproduced for the articulated connection of any two watch components.
  • the articulation device may comprise a single articulation axis. It more generally comprises at least one hinge pin.
  • a hinge pin may have shapes other than that shown.
  • the articulation portion of a hinge pin could have shapes other than a cylindrical shape.

  • the articulation axis comprises two articulation surfaces, to cooperate by friction with each of the two watch components. These two articulation surfaces can be substantially juxtaposed, on the same articulation portion of the articulation axis.
  • the hinge pin may comprise two hinge portions. It is through this or these articulation portions that the articulation axis mainly undergoes the various traction and shear stresses when the watch is worn.
  • the articulation axis comprises at least the articulation portion(s) having an entirely continuous peripheral surface, without edges, and preferably the articulation axis is entirely continuous, without edges, including the or the portions of least resistance.
  • Any section of at least the articulation portion(s) of the articulation axis along a longitudinal median plane and any section of at least the articulation portion(s) of the articulation axis along a transverse plane advantageously presents a contour of continuous shape. This shape allows it to withstand the mechanical stresses it undergoes. In fact, the stress concentrations are limited as much as possible, therefore optimizing the resistance of the hinge pin, by the fact that it does not include an edge or that its profile does not present an abrupt change in dimension .
  • the hinge pin comprises a portion of lower mechanical resistance.
  • it may comprise two or more portions of lower mechanical resistance. This or these portions of less mechanical resistance of the articulation axis are in a zone out of reach or distinct from the articulation portions, so that these portions of less resistance are not stressed when wearing the watch.
  • the hinge pin comprises at least one portion of less resistance, and this at least one portion of less resistance is positioned outside said articulation surfaces.
  • the at least one portion of lower resistance advantageously belongs to a functional portion of the hinge pin which is entirely inscribed in a cylinder of diameter less than the diameter of the hinge pin at the level of the one or more articulation portions.
