    Field of the invention
    The invention relates to a dressing component or movement for a timepiece comprising a structure which comprises at least one housing, and at least one removable element, said housing being arranged to receive a said removable element which is arranged for cooperating, in a service position, in direct or indirect support on a receiving surface that comprises said housing, by an attraction or repulsion force under the action of a magnetic and / or electrostatic field generated by said structure and / or said removable element around a field direction where said field is maximum, and where, when said removable element is not supported in said service position, said removable element is movable in said housing in at least one degree of freedom or in a direction of mobility parallel to said field direction with a clearance relative to said housing which is limited by at least one first mechanical stop between a first abutment surface of said structure and a first complementary abutment surface that comprises said removable elementThe invention further relates to a watch comprising at least one such dressing component or movement.The invention relates to the mechanical structure of timepieces, especially watches, and more particularly the components of clothing or movement.
    Background of the invention
    [0002] In watchmaking, and more particularly for watches, a mechanical technology is generally used for maintaining a component in a particular position. It can be an abutment with an elastic system, especially when a certain freedom of movement is necessary for the case of impact, or a solid attachment, by mechanical holding element such as screw, pinion, rivet, driving, or the like.
    Maintaining by a pre-stressed spring is not stable in time: such a spring, which must work with stress variations due to shocks to the watch, is subject to wear, as well as that each component subjected to percussive efforts in abutment.
    The use of mechanical holding elements often requires adapting one of the antagonistic components by machining a housing such as bore or tapping, or a support such as a journal or the like, which, on the one hand is not always possible in particular in the case of ceramic materials or sapphire or micro-machinable materials, and secondly can weaken the element considered due to reduced sections or / and failure primers. In addition, the force due to fixing, for example during a driving, riveting, or screwing, can generate significant constraints which are a potential source of additional problems, including deformation or a break. Certain geometries still prevent the use of rational mechanical solutions.
    The effects of mechanical stresses in a component, and in particular wear, are difficult to control because they strongly depend on the surface conditions and physical properties of the materials used. These properties themselves depend on the alloys used and the processes used, in particular heat treatment, surface treatment, and ion implantation. The specific tolerances of the different parameters of the processes and the materials make it impossible to know and to control precisely these physical properties. And reproducibility is not assured, because of these tolerances. Or the reduction of tolerance ranges, which provides a better reproducibility of phenomena, leads to costs too high for mass production.
    The use of glues or other adhesive products is limited by aging over time, and by the influence of the environmental factors of the watch: temperature, humidity, vibration.
    The theory governing magnetic interactions is, for its part, fully described by Maxwell's equations, and the remaining unknowns come from the magnetic materials used, which are better and better mastered, and from the difficulty to solve these equations analytically. and numerically with the smallest approximations possible. Nevertheless, from a macroscopic point of view these inaccuracies are sufficiently weak to make the magnetic systems reliable.
    Summary of the invention
    Also the invention proposes to solve the problem of the inalterable fixing of components or trim elements or clockwork, by their maintenance under the effect of a magnetic field and / or electrostatic.
    The invention relates to a component for dressing or movement for a timepiece comprising a structure which comprises at least one housing, and at least one removable element, said housing being arranged to receive a said removable element which is arranged for cooperating, in a service position, in direct or indirect support on a receiving surface that comprises said housing, by an attraction or repulsion force under the action of a magnetic and / or electrostatic field generated by said structure and / or said removable element around a field direction where said field is maximum, and where, when said removable element is not supported in said service position, said removable element is movable in said housing in at least one degree of freedom or in a direction of mobility parallel to said field direction with a clearance relative to said housing which is limited by at least one a first mechanical stop between a first abutment surface of said structure and a first complementary abutment surface that comprises said removable element, characterized in that said first mechanical abutment opposes the direct extraction of said removable element in said mobility direction .

    Detailed Description: Preferred Embodiments
    The invention provides an inalterable fixing of components or trim elements or clockwork, by their maintenance under the effect of a magnetic field and / or electrostatic.
    It is more particularly described with non-limiting examples of a magnetic application. The invention can also be implemented with the use of electrostatic fields, particularly through the use of electrets. Or by combining magnetic fields and electrostatic fields.
    In this magnetic application described below, a sustaining system is constructed, exploiting the forces in the broad sense, that is to say forces or torques, induced on a piece of magnetized material or ferromagnetic material immersed in a magnetic field. This effort depends on the magnetization of the material, or its magnetic permeability, and the intensity of the local magnetic field. In a particular embodiment, one or more magnets are positioned on a fixed part, and / or on an element that must be fixed. This element undergoes (or generates, in the case where it is itself magnetized and cooperates with a ferromagnetic magnetic or non-magnetic environment) an attraction or repulsion force that can be used to hold it in place.
    For lightweight elements, and if the size allows the presence of one or more magnets capable of generating a sufficient magnetic field, the magnetic force alone may be sufficient to retain an element during shocks.
    Different geometrical configurations are usable.
    It is thus possible to use the magnetic force to constrain a covering element or movement in the three directions, for example by keeping it in contact in a female trihedron which positions it, and which also constitutes a set of stops. positioning. The magnetic elements may be recessed with respect to the contact surfaces. Contact can also be made directly on surfaces of magnetic components.
    An alternative is the case where the magnetic force is used to constrain an element in one or two of the three directions, while a mechanical guidance is used to limit its movement in the other directions.
    For each of these variants, when the magnetic force is too small to withstand a shock, it is possible to introduce a safety stop, so as to limit the displacement and to avoid too much travel. The magnetic hold is therefore used to counteract low shocks, with an amplitude from which the magnetically fixed element peels off to abut. This mode of operation has the advantages of the springs, while causing a lower shock when returning to position. Indeed, the magnetic system, as opposed to the spring system, exerts a force that decreases with the distance of the part relative to its stance. The energy stored during an accidental shock, which is released when the element returns to position, is therefore lower.
    The force can be generated by two magnets, or a magnet near a ferromagnetic part (attraction), diamagnetic (repulsion) or paramagnetic (attraction).
    The element to be held in place can itself be ferromagnetic, diamagnetic or paramagnetic and be located near a magnet.
    In the case where the effort is caused by two magnets, they can work in attraction or repulsion; the work in attraction theoretically causes a slower aging of the magnetic system.
    The contact between antagonistic components, such as a structure 10 and a removable element 2, can be directly a contact of one of the magnets against the other, or in contact with a part of the component to be held against a stop positioning, which is not necessarily magnetic.
    The bearing surface against which a contact is maintained can undergo optimization of optimization of its tribological properties, and / or mechanical, and / or anti-wear. A surface layer, as visible in FIG. 4, may, for example, be corundum, diamond or a protective coating. This superficial layer can also be made of a material combining special tribological and magnetic properties, such as tungsten carbide.
    FIG. 4 illustrates an advantageous variant for replacing a screw fastener, when the carrier element can not be tapped, a magnet comes to press a removable element on a supporting structure; it is also possible to have a magnetic connection also between the removable element and the carrier structure.
    The attraction and magnetic repulsion phenomena can be used in different ways, and not only for maintaining an element in position. Thus, in a variant illustrated in FIG. 3, the magnetic system not only has a role of maintenance but also facilitates the function of setting up a removable element: in the upper position two magnets of inverted polarities are placed side by side; parallel to these two magnets, and in the lower position of the figure, a third magnet movable in a direction of introduction Dl longitudinal, is arranged to pass first in repulsion relative to the upper right magnet, before positioning itself as in the figure in attraction with the left upper magnet, on which it is ready to press in a race along the z direction of the figure; the upper right magnet then plays the role of a lock to prevent any unexpected exit of the lower magnet. During the introduction, an extra effort must be made to overcome the repulsion of the magnets, but once the system is in place it is maintained in both directions.
    FIG. 5 illustrates a variant with a magnetic recentering system where a movable element, including permanent magnets, is held against an annular beam composed of an alternation of paramagnetic or ferromagnetic parts on the one hand, and diamagnetic parts on the other hand, forming attractive parts and repulsive parts, which can also be composed of permanent magnets. The z-resistance of this system can be magnetic or mechanical; the element is refocused magnetically after each shock. This system is easily adaptable for a linear degree of freedom.
    To protect the outside of the watch, including the user or sensitive devices, against the magnetic fields of such a system, and to increase the efficiency of the holding system, it is possible, and advantageous, to introduce a ferromagnetic shield or to use the middle of the watch as such.
    Thus, with reference to the various figures, the invention relates to a component 10 for dressing or movement for timepiece.
    This component 10 comprises a structure 1 which comprises at least one housing 3, and at least one removable element 2. The housing 3 is arranged to receive such a removable element 2.
    This removable element 2 is arranged to cooperate, in a service position, in direct or indirect support on a receiving surface 4 that includes the housing 3, by a force of attraction or repulsion under the action of a magnetic and / or electrostatic field generated by the structure 1 and / or the removable element 2 around a DC field direction where the field is maximum.
    When the removable element 2 is not supported in the service position, the removable element 2 is movable in the housing 3 according to at least one degree of freedom or in a direction of mobility DM parallel to the direction DC field. This mobility is done with a displacement relative to the housing 3 which is limited by at least a first mechanical abutment between a first abutment surface 5 of the structure 1 and a first complementary abutment surface 6 that the removable element 2 comprises.
    According to the invention, this first mechanical stop opposes the direct extraction of the removable element 2 according to the direction of mobility DM.
    In an advantageous embodiment, the structure 1 comprises, connected to a housing 3, an introduction chamber 9, which is arranged to receive a removable element 2 according to an introduction direction D1 different from the direction of mobility DM, to a position of change of orientation that allows a change of direction of this removable element 2 to its operating position in the housing 3 in the direction of mobility DM.
    Preferably, this introduction chamber 9 then constitutes a mandatory passage for a removable element 2, before occupying its service position in such a housing 3.
    In a particular embodiment, in this introduction chamber 9, a magnetic field and / or electrostatic generated by the structure 1 or / and a removable element 2 tends to oppose the introduction of the removable element 2 , and pushing the removable element 2 out of the chamber 9 or / and towards the housing 3.
    A particular variant incorporates an additional element to the assembly: the removable element 2 is, in its service position, held in position on the receiving surface 4 by means of a spacer 7, which is mounted trapped between the receiving surface 4 and the removable element 2. It is understood that the functional element can then be both the removable element 2 that the spacer 7. In the latter case, the removable element 2 plays the role of a simple rivet for maintaining this spacer 7. This arrangement is particularly advantageous in cases where the constitution of the structure 1 does not allow the presence of implantation such as a tapping for the receipt of a screw , or similar. This allows, in particular, the realization of a structure 1 of the ceramic type comprising inlays of micro-magnets, or electrets, or magnetizable metal particles, or the like.
    In particular, the housing 3 is devoid of threading or tapping.
    In a particular embodiment, the structure 1 is ceramic, and comprises, at least in the vicinity of the surface of the at least one housing 3, an encrustation of magnets and / or electrets, and / or ferromagnetic particles. magnetizable.
    Advantageously, when the removable element 2 bears directly on the receiving surface 4 in the operating position, this removable element 2 comprises a complementary bearing surface 8 arranged to cooperate in a complementary manner in direct support with the surface. 4. And, advantageously, the receiving surface 4 and / or the complementary bearing surface 8 is a surface of a tribological or anti-wear coating.
    It is understood that the deflection of the removable element 2 can be limited, in the sense of its extraction, not only in the direction of mobility DM, but also in a direction different from the direction of mobility DM, by at least a second mechanical abutment between a second abutment surface 50 of the structure 1 and a second complementary abutment surface 60 that the removable element 2 comprises.
    The magnetic or / and electrostatic retention of the removable element 2 in its housing 3 ensures the maintenance of this removable element 2 during a shock of low intensity which is subject to the element 2; the mechanical stops provide safety in case of shock or acceleration of much higher intensity. Advantageously, to ensure damping, the removable element 2 is held in its housing 3 embedded in a viscous medium damping, or in a silicone.
    In a particular variant, the housing 3 comprises an alternation of repulsive and attractive surfaces relative to the removable element 2, tending to position this removable element 2 in at least one particular position, and preferably also in an orientation special.
    Similarly, in a particular variant, it is the removable element 2 which comprises an alternation of repulsive and attractive surfaces relative to the housing 3, tending to position the removable element 2 in a position, and / or a particular orientation.
    In particular, the geometric envelope of repulsive and attractive surfaces constitutes a surface of revolution around the DC field direction.
    Means for positioning the removable element 2 may be cumulative to the preceding provisions. In a variant, the housing 3 comprises a dihedron arranged to precisely position and orient the removable element 2 in the housing 3. In a variant, the removable element 2 comprises a dihedron arranged to precisely position and orient the removable element 2 in housing 3.
    In particular, the housing 3 is smooth.
    In particular, the structure 1 comprises or constitutes a ferromagnetic shielding.
    FIG. 7 illustrates an example where removable elements 2 constituted by a dial and display markers are magnetically fixed on a middle part 10.
    FIG. 9 shows a watch middle constituting such a component 10, with a structure 1 comprising a base dial 1C, on which is mechanically attached a pad 1B having a lower magnet 1A, glued or driven. On this stud 1B is disposed an upper dial 2B sapphire, including an annular dial, bonded to an upper magnet 2A cooperating with the lower magnet 1A of the stud. This pad 1B is a bowl and comprises the lower magnet 1A at the bottom of a bore 5 for receiving the circumference 4 of the upper magnet 2A.
    FIG. 12 represents, in section passing through its axis, a watchmobile 2, pivotally guided in a first conventional bearing 11 at a first end, and indirectly via a spacer 17 at a second end, also in at least one conventional bearing. Here the mobile 2 pivots, at a bearing surface 22, in a secondary bearing 16 in this spacer 17, which pivots, at bearings 18 and 19 that it comprises, in bearings 14 and 12 respectively connected to a plate 15 and a bridge 13. The structure 1 comprises at least one magnet 31, which is arranged beyond the first bearing 11, and this magnet 31 cooperates with the corresponding distal end 23 of the mobile 2, at a housing 3. The mobile 2 comprises a shoulder 21 in the vicinity of the first bearing 11. The assembly is here such that the distal end 23 of the mobile 2 always remains at a distance from the corresponding surface 32 of the magnet 31.
    The magnet 31 is arranged to attract the mobile 2, and the magnet 31 tends to press the shoulder 21 of the mobile on a bearing surface 110 of the first bearing 11, in the immediate vicinity of the magnet 31. In an alternative embodiment, the mobile 6 is made of steel, and the magnet 31 is of the neodymium-iron-boron type and dimension so as to prevent, in case of shock, the output of the mobile 2 of the first bearing 11. return force for a magnet 31, diameter 0.60 mm and height 0.80 mm and a residual field of 1.4 T, reaches 0.016 N at 0.10 mm distance between the magnet and the mobile.
    The invention also relates to a watch 100 comprising at least one such dressing component 10 or movement.
    In sum, the use of magnetic fields and / or electrostatic for the relative maintenance of dressing components or movement has many advantages:reproducibility of efforts and assembly parameters;liberation of tribological constraints;reduction of wear problems due to shocks on a watchincreased rigidity of supporting structures that do not require deep drilling or tapping;maintaining timepieces whose material, and / or reduced sections, and / or fragility, and / or geometry do not allow mechanical maintenance without rupture;Fine refocusing ability after shock;fixing any element, in particular covering or movement, by magnetic and / or electrostatic forces.
    Those skilled in the art will know, still, use the invention for other components that components dressing or movement, and especially to replace friction in the case of momentary positions, such as means of date display, date discs or the like.
