Definitions

  • a rotating bezel system includes a ceramic rotating bezel.
  • the invention also relates to a watch case comprising a middle part and the rotating bezel system rotatably mounted on the middle part.
  • the invention further relates to a watch comprising the watch case.
  • Known rotating bezel systems include a ceramic rotating bezel, an annular ring, and an annular joint connecting the rotating bezel and the annular ring.
  • the annular ring is generally driven into the rotating bezel.
  • the annular ring is intended to cooperate with an element which is angularly integral with a watch case middle part on which the rotating ceramic bezel is mounted, such as an open spring with flanges.
  • the annular seal is inserted between the annular ring and the rotating bezel, and forms a friction element configured to hold the bezel on the annular ring.
  • a drawback of such a rotating bezel system is that the annular seal does not provide a sufficiently strong connection between the rotating bezel and the ring, in particular when the system is dismantled.
  • a weak connection provided by the annular seal may have the consequence that the bezel is released from the ring, the latter remaining then on the middle of the watch case. This leads to unnecessary and tedious operations for the operator responsible for dismantling the system, which is detrimental to the practicality and reliability of the latter.
  • the object of the invention is therefore to provide a simple and reliable rotating bezel system making it possible to secure the holding of the rotating bezel on the annular ring, in particular during the dismantling of the system, and overcoming the aforementioned drawbacks of the state of the art. .
  • the invention relates to a rotating bezel system which comprises the features mentioned in independent claim 1.
  • the holding of the rotating bezel on the annular ring is improved, in particular when the system is dismantled.
  • the or each blocking element is configured to block any relative rotation between the ring and the bezel.
  • the system comprises at least two blocking elements distributed over 360 °. This makes it possible to distribute the mechanical stresses exerted on the system as well as to limit the play between the annular ring and the rotating bezel.
  • the system comprises four locking elements distributed over 360 °, the four locking elements being spaced two by two by 90 °.
  • the annular seal is formed from a polymer material, for example asutane.
  • the seal being of flexible material, it can deform and compress, and it thus makes it possible to compensate for the play and to tighten (secure) the parts together.
  • At least one opening for receiving the or one of the locking element (s) is machined locally in the annular ring. This makes it possible to facilitate the installation of the blocking element (s) in the system.
  • the annular seal is driven between the annular ring and the or each locking element.
  • Such an annular seal thus configured makes it possible to form a friction element to prevent any sliding between the blocking element (s) and the annular ring, and also makes it possible to prevent the locking elements from returning.
  • the annular rotating bezel system is formed of 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 caseband, also allowing easy disassembly. This further simplifies the assembly and disassembly of the system.
  • the clip-on mounting system used forms a free hooking system, thus retaining the usual mounting principles for rotating bezels with flanged spring.
  • the invention also relates to a watch case comprising a middle part as well as the rotating bezel system described above, and which comprises the characteristics mentioned in dependent claim 13.
  • the invention also relates to a watch comprising the watch case described above, and which comprises the characteristics mentioned in dependent claim 14.
  • the figure 1 shows 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 a rotating bezel system 6 as well as a watch movement, the watch movement not being not shown in the figures for reasons of clarity.
  • the rotating bezel system 6 is rotatably mounted on the middle part 4.
  • the rotating bezel system 6 is formed of an independent module.
  • the caseband 4 is annular in shape.
  • the middle part 4 carries an element which is angularly integral with the latter, this element not being shown in the figures for reasons of clarity.
  • the element which is angularly integral with the middle part 4 is for example a spring ring with flanges, without this being limiting in the context of the present invention.
  • watch box 2 taken as an example in figures 1 to 11 , 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.
  • the rotating bezel system 6 comprises a rotating bezel 14, an annular ring 16, an annular seal 18 connecting the rotating bezel 14 and the annular ring 16, and at least one element 20 for locking the annular ring 16 on the bezel.
  • rotating 14 Preferably, the system 6 comprises at least two locking elements 20 distributed over 360 °.
  • the system 6 comprises four locking elements 20 distributed over 360 °, the four locking elements 20 being spaced two by two by 90 °.
  • the rotating bezel 14 is made of ceramic, typically based on alumina, zirconia or silicon nitride.
  • the annular ring 16 is placed in the rotating bezel 14, and cooperates with the element angularly integral with the middle part 4.
  • the annular ring 16 is a toothed ring, preferably made of metal. According to this particular exemplary embodiment, the annular ring 16 is then engaged with the teeth of the element which is angularly integral with the middle part 4.
  • the annular ring 16 comprises on a lower face at least two receiving openings 22 distributed on 360 °.
  • the annular ring 16 comprises four reception openings 22 distributed over 360 °, the four reception openings 22 being spaced two by two by 90 °.
  • the annular ring 16 is typically made of a metallic material, for example steel or even gold.
  • the annular seal 18 is driven between the annular ring 16 and each locking element 20.
  • the annular seal 18 is received in a groove 24 formed in the ring 16, as visible on the figure 3 .
  • the Ring seal 18 is made of a polymeric material, for example asutane.
  • the annular seal 18 forms a friction element which makes it possible to prevent any sliding between the blocking elements 20 and the annular ring 16, and which also makes it possible to ensure the non-return of the blocking elements 20 when the latter are positioned in the system.
  • each blocking element 20 is configured to block any relative rotation between the annular ring 16 and the bezel 14.
  • each locking element 20 has an elongated body in a longitudinal direction of extension D1.
  • the body has a first main part 28a, and a second part 28b forming a rim and extending from the first part 28a in a substantially orthogonal direction.
  • the body thus has a cross section substantially in the shape of an “L”, the first part 28a of the body forming the main branch of the “L”, the second part 28b of the body forming the foot of the “L”.
  • the annular ring 16 In order to receive the locking element (s) 20, the annular ring 16 has locally, on its upper part to the right of a corresponding receiving opening 22, at least one shoulder 30 defining an internal clearance 32.
  • the rotating bezel 14 locally defines on its inner periphery at least one internal groove 34.
  • the second part 28b of each blocking element 20 is received in one of the receiving grooves 34 formed on the bezel 14.
  • the upper surface of the second part 28b of each blocking element 20 is in turn resting against a lower surface of the annular ring 16, more precisely against a lower surface of one of the shoulders 30, as illustrated in figure 2 .
  • Each locking element 20 thus makes it possible to angularly secure the assembly formed by the annular ring 16 and the bezel 14.
  • each locking element 20 is made of the same material as that in which the annular ring 16 is made, typically of a metallic material, for example steel or even gold.
  • the annular ring 16 is first installed by placing it within the rotating bezel 14 previously positioned. To do this, and as shown in the figure 7 , the openings 22 and the shoulders 30 are used so as to be aligned with the internal grooves 34 of the bezel 14, thus ensuring correct positioning between the ring 16 and the bezel 14.
  • each locking element 20 is inserted through one of the receiving openings 22 made in the ring 16, with the second part 28b forming the foot of the “L” positioned so as to be inserted first into the opening 22. This insertion is facilitated by the presence of the internal clearance 32 defined by the corresponding shoulder 30 provided on the ring 16. As illustrated in FIG. figure 10 , the second part 28b of each locking element 20 is then slipped into one of the internal grooves 34 formed in the bezel 14, the upper surface of the second part 28b bearing against a lower surface of the corresponding shoulder 30.
  • the annular seal 18 is put in place to finalize the assembly of the system 6. To do this, the annular seal 18 is driven between the annular ring 16 and each locking element 20. In the areas of the system 6 where it does not. there are no elements of blocking 20, the annular seal 18 is received in the groove 24 formed in the ring 16, as visible on the figure 3 .
