    Description
    TECHNICAL FIELD OF THE INVENTION The invention relates to an annular rotating bezel system.
    The invention also relates to a watch case comprising a middle part and the annular rotating bezel system mounted for rotation on the middle part.
    The invention further relates to a watch comprising the watch case. The watch is for example a diving watch, without this being limiting in the context of the present invention.
    STATE OF THE ART [0004] Known annular rotating spectacle systems include a rotating bezel, a toothed ring, and a spring ring. Such a rotating bezel system is for example described in patent document EP 2 672 333 A1. The spring ring is angularly secured to the rotating bezel, and the toothed ring is angularly secured to the middle part. The toothed ring has several teeth regularly distributed around its outer periphery, in this case 120 teeth in the embodiment given in this document. The spring ring extends in a plane in which it is capable of deforming elastically along a radius, and cooperates elastically with the toothed ring. To do this, three lugs in the form of elastic arms and intended to cooperate with the teeth of the toothed ring are formed in an inner periphery of the spring ring, by cutting the latter. The three pins are evenly distributed around the inner periphery of the spring ring. Therefore, whatever the position of the bezel, the three pins are always engaged with the teeth of the toothed ring at the same time, which leads to 120 stable positions for the rotating bezel. The number of positions therefore corresponds to the number of teeth. The resolution of the indexing of the position of the rotating bezel is therefore limited by the number of possible positions in total for the latter, in this case 120 positions. However, the greater the number of teeth for a given diameter, the smaller the size of the teeth, which implies a high wear factor for the latter. It is therefore desirable to find a technical solution making it possible to ensure, for a given bezel diameter, a number of stable positions higher than the number of teeth in the teeth of the ring, and this without increasing the wear of the toothing of the ring.
    SUMMARY OF THE INVENTION The object of the invention is therefore to provide an annular rotating bezel system making it possible, with the same number of teeth as the toothed ring compared to the systems of the prior art, to obtain a more large number of possible stable positions for the rotating bezel, and overcoming the aforementioned drawbacks of the prior art.
    To this end, the invention relates to an annular rotating bezel system which comprises the characteristics mentioned in independent claim 1.
    Particular forms of the system are defined in dependent claims 2 to 16.
    An advantage of the present invention is to allow, with an equal number of teeth for the toothed ring compared to the systems of the prior art, to obtain a greater number of stable positions possible for the rotating bezel. Indeed, thanks to the configuration according to which the or each angle of offset between two successive lugs has a value distinct from an integer sub-multiple of 360 degrees, a single lug is elastically and radially engaged with the teeth of the ring toothed in each position of the telescope. The total number of possible positions for the bezel is then given by the result of the multiplication between the number of pins on the spring ring, and the number of teeth on the toothed ring. This makes it possible to obtain as many stable positions as possible for the rotating bezel.
    Conversely, it is possible for example, thanks to the system according to the invention, to increase the size of the teeth and reduce their number on the toothed ring, with a view to reducing their wear, and this while retaining a number of stable positions for the telescope identical to that of the systems of the prior art.
    Advantageously, the spring ring comprises at least two thinned portions arranged to increase the flexibility of the spring ring in its plane, each lug extending from one of the thinned portions. This increases the flexibility of the spring ring in its plan. Indeed, thanks to the thinned portions which it presents, the spring ring works in bending in its plane, allowing the pins which it carries to mesh and to degenerate from the toothed ring according to the rotation of the bezel. This makes it possible to reduce the width necessary for the operation of the spring ring in the system, and therefore to obtain a gain in overall dimensions in width of the assembly.
    Advantageously, the rotating bezel comprises at least one bead extending over an internal lateral face of the bezel, and the spring ring has, on an outer periphery, at least one notch in which the bead of the bezel is engaged . This allows the spring ring to be easily linked in rotation to the rotating bezel, while facilitating the positioning of the spring ring in the bezel.
    Advantageously, the toothed ring has, on an inner periphery, at least one bead intended to be received in a notch provided in a cylindrical outer surface of the middle part. This allows a solidarization year
    CH 715 239 A2 easy gular from the toothed ring to the middle, while facilitating the positioning of the toothed ring on the middle and allowing to guide the rotating bezel system for its mounting on the middle.
    According to a first embodiment of the invention, the teeth of the toothed ring and the lugs of the spring ring each have an asymmetrical shape in the plane defined by the spring ring. In this first embodiment, the spring ring can rotate relative to the toothed ring in only one predefined direction: clockwise or counterclockwise depending on the shape chosen for the teeth. This first embodiment of the invention therefore corresponds to a unidirectional rotating bezel.
    According to a second embodiment of the invention, the teeth of the toothed ring and the lugs of the spring ring each have a symmetrical shape in the plane defined by the spring ring. In this second embodiment, the spring ring can rotate relative to the toothed ring in one or the other of the two directions: clockwise or counterclockwise. This second embodiment of the invention therefore corresponds to a bidirectional rotating bezel.
    Advantageously, the annular rotating bezel system is formed by an independent module, said module being configured to be clipped onto the middle part. This makes it possible to obtain a simple and practical assembly of the rotating bezel system on the middle, also allowing easy disassembly. This simplifies the manufacturing process of the watch case. The clip-on mounting system used forms a free spitting system.
    To this end, the invention also relates to a watch case comprising the annular rotating bezel system described above, and which comprises the characteristics mentioned in dependent claim 17.
    A particular form of the watch case is defined in dependent claim 18.
    To this end, the invention also relates to a watch comprising the watch case described above, and which comprises the characteristics mentioned in dependent claim 19.
    BRIEF DESCRIPTION OF THE FIGURES The objects, advantages and characteristics of the annular rotating bezel system according to the invention will appear better in the following description on the basis of at least one non-limiting embodiment illustrated by the drawings in which:
    Figure 1 is an exploded perspective view of the annular rotating bezel system according to the invention, comprising a spring ring and a toothed ring;
    fig. 2 to 5 are top views of the annular rotating bezel system of FIG. 1, according to a first embodiment of the invention, and in different positions of the telescope; and fig. 6 to 9 are top views of the annular rotating bezel system of FIG. 1, according to a second embodiment of the invention, and in different positions of the telescope.
    DETAILED DESCRIPTION OF THE INVENTION [0020] FIG. 1 represents a watch 1 provided with a watch case 2. The watch case 2 typically comprises a middle part 4. The watch case 2 also comprises an annular rotating bezel system 6 as well as a watch movement which extends in a plan, the watch movement not being shown in the figures for reasons of clarity. The annular rotating bezel system 6 is mounted for rotation on the middle part 4. Preferably, as illustrated in FIG. 1, the annular rotating bezel system 6 is formed by an independent module. The annular rotating bezel system 6 is for example clipped onto the middle part 4.
    As illustrated in FIG. 1, the middle part 4 is of annular shape. The middle part 4 comprises a cylindrical outer surface 8. The cylindrical outer surface 8 is for example provided with a peripheral shoulder defined by a side wall 12a and a base 12b. This peripheral shoulder serves as a housing for the rotating bezel system 6. The side wall 12a comprises an annular projection or bead 13 extending over the entire perimeter of the side wall 12a and allowing the spitting of the rotating bezel system 6 to the middle 4, by clipping. The annular rotating bezel system 6 is based on the base 12b. The rotating bezel system 6 is thus mounted on the middle part 4, from above the latter, allowing the system 6 to be blocked in an axial direction perpendicular to the plane of the watch movement, while allowing rotation of the bezel around the middle part 4. In the watch case 2 taken as an example in figs. 1 to 9, the configuration of the watch case is substantially circular. However, the invention is in no way limited to such a configuration of the watch case, nor to the other arrangements described above for the middle part. The middle part can be made of metal, typically steel, titanium, gold. , platinum or ceramic typically based on alumina, zirconia or silicon nitride.
    The annular rotating bezel system 6 comprises a rotating bezel 14, a toothed ring 18 and a spring ring 20. Preferably, the system 6 further comprises an annular retaining ring 16. More preferably, the system 6 comprises also a decor ring 22 forcibly engaged on the rotating bezel 14. The decor ring
    CH 715 239 A2 for example carries graduations, typically diving graduations in the case of a diving watch 1. The decor ring 22 is for example ceramic.
    The rotating bezel 14 is of annular shape and comprises an upper face 23a visible to the user and a lower face 23b. As illustrated in fig. 1, the rotating bezel 14 is for example provided on an inner periphery with an annular rim 24. The annular rim 24 cooperates by clipping with the protrusion 13 of the middle part 4, and forms with the latter a free hooking system. The rotating bezel 14 is for example made of metal but could be made of any other material, for example ceramic.
    The annular ring 16 holds the toothed ring 18 and the spring ring 20 in the bezel 14, in an axial direction perpendicular to the plane of the watch movement. This makes it easier to mount the rotating bezel 14 on the middle part 4. Preferably, the annular ring 16 is driven into the rotating bezel 14, securing it to the latter. In an alternative embodiment not shown in the figures, the annular ring 16 is secured to the middle part 4.
    The annular ring 16 rests on the base 12b of the middle part 4, and thus surrounds the cylindrical outer surface 8 of the middle part 4. The annular ring 16 is configured to cooperate with the cylindrical outer surface 8 to allow rotation of the rotating bezel 14 on the middle part 4. The annular retaining ring 16 is for example a flat ring. According to other alternative embodiments of the invention, the annular retaining ring may comprise a simple annular ring of rectangular section, especially its periphery driven into the bezel 14.
    The toothed ring 18 includes a toothing 26. The toothing 26 is provided with several teeth regularly distributed around a periphery of the toothed ring 18, typically on an outer periphery, over 360 degrees. Preferably, the toothed ring 18 also has, on its inner periphery, at least one bead 34 received in a notch 36 provided in the cylindrical outer surface 8 of the middle part 4. In the exemplary embodiments illustrated in FIGS. 1 to 9, the toothed ring 18 comprises three beads 34 distributed over 360 degrees and spaced two by two by 120 degrees. The cylindrical outer surface 8 of the middle part 4 comprises three corresponding notches 36. This bead system 34 / notches 36 allows easy angular attachment of the toothed ring 18 to the middle part 4, while facilitating the positioning of the toothed ring 18 on the middle part 4. This system also makes it possible to guide the rotating bezel system 6 for its mounting on the middle part. Thus, by pressing from the top of the system 6, the beads 34 are engaged in the notches 36, making it possible to snap the elements inside the system 6 and to clip the system 6 onto middle 4.
    The toothed ring 18 is formed from a single piece of material. The toothed ring 18 is for example made of a metal alloy, in particular a cobalt-based alloy (40% Co, 20% Cr, 16% NI and. 7% Mo) commercially called phynox or stainless steel. for example 316L. As a variant, the toothed ring 18 can be made of a thermoplastic material, in particular a thermostable semi-crystalline thermoplastic material such as for example polyarylamide (Ixef®), polyetheretherketone (PEEK) or also a ceramic material such as zirconia or alumina.
    As shown in Figs. 2 to 9, the toothed ring 18 is arranged to fit into the spring ring 20, that is to say that the toothed ring 18 is dimensioned to be able to be placed in the spring ring 20. The toothed ring 18 and the spring ring 20 are concentric and coplanar, and are held between the lower face 23b of the bezel 14 and an upper face of the retaining ring 16.
    The spring ring 20 extends in a plane in which it is capable of deforming elastically along a radius. The spring ring 20 cooperates elastically with the toothed ring 18. To do this, the spring ring 20 comprises at least two lugs 40, each lug 40 being configured to be elastically and radially engaged with the teeth 26 of the ring toothed 18 in at least one position of the telescope 14. In the exemplary embodiments illustrated in FIGS. 1 to 9, the spring ring 20 comprises three lugs 40. The lugs 40 are offset between them by an offset angle ûa, ûb, De. Each offset angle ûa, ûb, De between two successive lugs 40 has a value distinct from an integer sub-multiple of 360 degrees, as will be detailed later. In this way, in each position of the rotating bezel 14, a single lug 40 is elastically and radially engaged with the teeth 26 of the toothed ring 18. Thus, in each position of the bezel 14, when one of the lugs 40 is elastically and radially engaged with the teeth 26, the remaining lug (s) 40 are balanced on teeth of the toothed ring 18. In other words, this or these latter lug (s) 40 are then not engaged with the toothing 26. In this configuration, in each position of the bezel 14, one and only one lug 40 is in contact with the toothed ring 18 so that there is a rest position in which this pin 40 is located in a hollow between two teeth of the toothed ring 18. The other pins 40 are then in equilibrium on the teeth of the toothed ring 18, as will be described later. When the user grasps the bezel 14 and turns it, due to the flexibility of the spring ring 20, the spring ring 20 deforms elastically in its plane, allowing the first lug 40 to disengage from the hollow of the 'toothed ring 18 and to be balanced on adjacent teeth. Another lug 40, different from the first lug, then re-engages in the toothing 26 of the toothed ring 18. The bezel 14 then effectively rotates from a corresponding angular sector, to a new position.
    Preferably, the spring ring 20 comprises at least two thinned portions 38. Each lug 40 extends from one of the thinned portions 38. In the exemplary embodiments illustrated in FIGS. 1 to 9, the spring ring 20 comprises three thinned portions 38 distributed over 360 degrees, each thinned portion 38 having a lug 40 arranged in a middle portion of the thinned portion 38. The three thinned portions 38 are spaced two by two from 120 degrees. The thinned portions 38 are arranged to increase the flexibility of the spring ring 20 in its plane. This
    CH 715 239 A2 configuration allows, when the toothed ring 18 is inserted inside the spring ring 20, that one of the lugs 40 cooperates with the teeth 26 of the toothed ring 18.
    Preferably, as illustrated in figs. 1 to 9, the thinned portions 38 are thinned radially.
    More preferably, the spring ring 20 has on its outer periphery, at least one notch 42 in which a bead of the bezel 14 is engaged to link these two elements in rotation. In the exemplary embodiments illustrated in FIGS. 1 to 9, the spring ring 20 comprises three notches 42 distributed over 360 degrees and spaced two by two by 120 degrees, and the rotating bezel 14 comprises, on an internal lateral face, three corresponding beads. The notches 42 are formed in portions 46 of the spring ring 20 which are thicker than the thinned portions 38, in the middle parts of these portions 46. Thus, the pins 40 and the notches 42 form an alternation on the spring ring 20 This bead / notch system makes it possible to easily link in rotation the spring ring 20 to the rotating bezel 14, while facilitating the positioning of the spring ring 20 in the bezel 14.
    The spring ring 20 is formed from a single piece of material. The spring ring 20 is for example made of a metal alloy having good spring properties, that is to say which easily deforms elastically while being able to deform significantly without undergoing plastic deformation, in particular phynox ® or amorphous metal alloys. Of course, the spring ring 20 can also, as a variant, be made of a synthetic material.
    According to a first embodiment, the teeth of the toothed ring 18 and the lugs 40 of the spring ring 20 have an asymmetrical shape in the plane defined by the spring ring 20. The asymmetrical shape is for example a so-called “wolf tooth” shape, that is to say that the teeth and the pins have substantially the shape of a right triangle. In the position in which a lug 40 engages, the hypotenuse of the triangle formed by this lug 40 of the spring ring extends along the hypotenuse of the triangle formed by one of the teeth of the toothed ring 18. In this embodiment, the spring ring 20 can rotate relative to the toothed ring 18 in only one predefined direction: clockwise or counterclockwise depending on the shape chosen for the teeth and the lugs. This first embodiment of the invention therefore corresponds to a unidirectional rotating bezel 14.
    According to a second embodiment, the teeth of the toothed ring 18 and the lugs 40 of the spring ring 20 have a symmetrical shape in the plane defined by the spring ring 20. The symmetrical shape is for example a isosceles triangle or equilateral triangle shape. In this exemplary embodiment, the spring ring 20 can rotate relative to the toothed ring 18 in one or the other of the two directions: clockwise or counterclockwise. This second embodiment of the invention therefore corresponds to a bidirectional rotating bezel 14.
    A first embodiment of the invention will now be described with reference to Figs. 2 to 5. According to this first embodiment, the toothed ring has 120 teeth regularly distributed over its outer periphery, and the spring ring 20 comprises three lugs 40a, 40b, 40c. The number of possible positions in total for the bezel 14 given by the result of the multiplication between the number of lugs 40a-40c on the spring ring 20, and the number of teeth on the toothed ring 18, the system of annular rotating bezel 6 according to this first embodiment has 360 possible stable positions. The spring ring includes a first lug 40a, a second lug 40b, and a third lug 40c. As illustrated in fig. 2, the first and second pins 40a, 40b are offset from one another by an offset angle ûa, the second and third pins 40b, 40c are offset from each other by an offset angle ûb, and the first and third pins 40a, 40c are offset from each other by an offset angle ûc. The value of the offset angle ûa is 121 degrees, the value of the offset angle ûb is 121 degrees, and the value of the offset angle ûc is 118 degrees. Thus, the three pins 40a-40c are distributed over an inner periphery of the spring ring 20 so that the angular spacing of the pins 40a-40c on the spring ring 20 is offset by 1 degree relative to a regular symmetrical distribution . In addition, as indicated previously, each angle of offset ûa, ûb, ûc between two successive lugs 40a, 40b, 40c has a value distinct from an integer sub-multiple of 360 degrees.
    [0037] FIG. 2 shows the system 6 in a position of the bezel 14 "at 12 o'clock". In this position, only the first lug 40a of the toothed ring 20 is engaged with the toothing 26. The second and third lugs 40b, 40c are balanced on teeth of the toothed ring 18. When the user grasps of the bezel 14 and rotates it by 1 degree clockwise, the system 6 adopts the configuration shown in fig. 3. In this configuration, only the third lug 40c of the toothed ring 20 is engaged with the toothing 26. The first and second lugs 40a, 40b are balanced on the teeth of the toothed ring 18. When the user takes hold of the bezel 14 and turns it 1 degree clockwise, therefore 2 degrees from the "12 o'clock" position, the system 6 adopts the configuration shown in FIG. 4. In this configuration, only the second lug 40b of the toothed ring 20 is engaged with the toothing 26. The first and third lugs 40a, 40c are balanced on the teeth of the toothed ring
    18. When the user takes hold of the bezel 14 and rotates it 1 degree clockwise, therefore 3 degrees relative to the “12 o'clock” position, the system 6 adopts the configuration shown at fig. 5. In this configuration, the first lug 40a of the toothed ring 20 is again alone in engagement with the toothing 26. The second and third lugs 40b, 40c are in equilibrium on the teeth of the toothed ring 18.
    A second embodiment of the invention will now be described with reference to Figs. 6 to 9. According to this second embodiment, the toothed ring has 40 teeth regularly distributed around its outer periphery, and the spring ring 20 comprises three lugs 40a, 40b, 40c. The annular rotating bezel system 6 according to this second
    CH 715 239 A2 embodiment thus presents 120 possible stable positions. The spring ring includes a first lug 40a, a second lug 40b, and a third lug 40c. As illustrated in fig. 6, the first and second lugs 40a, 40b are offset from one another by an offset angle ûa, the second and third lugs 40b, 40c are offset from each other by an offset angle ûb, and the first and third lugs 40a, 40c are offset from each other by an offset angle ûc.
    [0039] FIG. 6 shows the system 6 in a position of the bezel 14 "at 12 o'clock". In this position, only the first lug 40a of the toothed ring 20 is engaged with the toothing 26. The second and third lugs 40b, 40c are balanced on teeth of the toothed ring 18. When the user grasps of the bezel 14 and rotates it 3 degrees clockwise, the system 6 adopts the configuration shown in fig. 7. In this configuration, only the third lug 40c of the toothed ring 20 is engaged with the toothing 26. The first and second lugs 40a, 40b are balanced on the teeth of the toothed ring 18. When the user takes hold of the bezel 14 and turns it 3 degrees clockwise, therefore 6 degrees from the "12 o'clock" position, the system 6 adopts the configuration shown in FIG. 8. In this configuration, only the second lug 40b of the toothed ring 20 is engaged with the toothing 26. The first and third lugs 40a, 40c are balanced on teeth of the toothed ring 18. When the user takes hold of the bezel 14 and turns it 3 degrees clockwise, therefore 9 degrees from the "12 o'clock" position, the system 6 adopts the configuration shown in FIG. 9. In this configuration, the first lug 40a of the toothed ring 20 is again alone in engagement with the toothing 26. The second and third lugs 40b, 40c are in equilibrium on the teeth of the toothed ring 18.
    The previous description of the annular rotating bezel system according to the invention was made with reference to a toothed ring angularly secured to the middle part, and to a spring ring angularly secured to the rotating bezel. However, those skilled in the art will understand that the reverse configuration is possible without departing from the scope of the present invention, that is to say that the toothed ring can be angularly secured to the rotating bezel, and the ring comes out angularly. secured to the middle. In addition, although the invention has been described with reference to a spring ring provided with three lugs, the invention applies in the same way for rotating bezel systems provided with spring rings comprising two lugs, or even spring rings with four or more lugs.
