Definitions

  • the invention relates to the field of watchmaking. It concerns more precisely a watch case provided with a rotating bezel.
  • Watch cases with a rotating bezel are known and marketed by many watch companies. They are generally intended for the practice of sport, for example on diving watches.
  • the bezel which has time or other indications, can take any angular position, or predetermined positions through a detent device.
  • the bezel is usually arranged on the middle part, directly accessible to the user.
  • a watch used in an aggressive environment related to the practice of a sport, such a watch can quickly become clogged.
  • the telescope may then turn with difficulty or even hang, requiring the intervention of a specialist in watchmaking.
  • some rotating glasses are easily removable. The user himself can disassemble it and perform a regular cleaning.
  • Such a telescope is described in the document WO 97/45775 which offers a watch case formed of a middle part, and a bezel rotatably mounted on the middle by means of a connecting ring freely mounted in rotation in a groove made in the caseband.
  • the bezel is locked axially with the fingers extending radially and cooperating with the ring.
  • the present invention overcomes these disadvantages by providing a watch case provided with an easily removable rotating bezel devoid of fixing screws.
  • the means for axially locking the bezel on the middle part also comprise second rigid members mounted on the first of the elements of the middle case-bezel assembly, and third rigid members mounted on the second of the elements of the middle case assembly.
  • bezel, the second and third rigid members being arranged so as to cooperate together to axially lock the bezel and disengage in the relative position of the bezel relative to the middle part.
  • the box according to the invention further comprises a connecting member of the bezel to the middle part, and positioning means of this connecting member, which is rigidly mounted on the first of the elements of the middle set - bezel using the positioning means.
  • the elastic members are integral with this connecting member.
  • the second rigid members may also be integral with this connecting member.
  • the second and third rigid members are radially extending fingers, integral respectively with the connecting member and the second of the elements of the middle-lunette assembly. They are complementary to each other in the relative position of the bezel relative to the middle part in which the first rigid members cooperate with the elastic arms.
  • the connecting member is a split ring having a central portion and a peripheral portion having the fingers.
  • the middle case - bezel further comprises a detent system defining predetermined angular positions of the bezel with reference to the middle part.
  • the relative position of the bezel relative to the middle part is located between two predetermined positions by the latching system
  • the elastic members are angularly extending arms and axially flexible, and said first rigid members are radially extending fingers and sized to pass into the space created by the flexion of the arms.
  • the watch case partially shown in Figure 1 comprises, conventionally, a middle part 10 and an ice 12, mounted on the middle part 10, and forming with it a housing 14 for receiving a movement.
  • the watch case further comprises a case 18 comprising a substantially cylindrical inner side 20 and a face lower 22 substantially flat.
  • the bezel 18 is rotatably mounted on the middle part 10.
  • the upper part of the caseband 10 forms a substantially cylindrical portion 24 of axis AA (FIG. 4), the outer side of which constitutes a guiding surface 26 positioning the bezel radially.
  • the lower part of the middle portion extends radially with respect to the cylindrical portion 24, so as to form a bearing surface 28 cooperating with the face 22 and intended to axially lock the bezel 18 direction of the bottom of the box.
  • a circular groove 32 made in the outer flank of the cylindrical portion 24, serves as a housing for the ring 30.
  • the bezel 18 itself is provided with a projecting circular portion 34 integral with its inner side 20 and abutting, by its upper surface, against the ring 30. Moreover, the flank of the circular portion 34 abuts against the guide surface 26.
  • the middle part 10 and the bezel 18 are furthermore provided with a detent device 36 intended to permit rotation only in one direction and to position by step of the telescope 18. It is formed of a toothing in teeth. saw 38 secured to the bezel 18 and a pawl 40 integral with the middle 12. A clearance 42 formed in the lower face 22 of the bezel 18, immediately below the circular portion 34, serves as a housing for the toothing 38, while a groove 44 formed in the bearing surface 28 serves as a housing and positioning means of the pawl 40. The pawl 40 and sawtooth teeth 38 cooperate in a manner well known to those skilled in the art. Note that the latching device 36 is optional. It is understood that the teeth could just as easily be made directly in the telescope 18.
  • the rotating bezel 18 is removable.
  • the characteristics of the watch case according to the invention appear more clearly with reference to FIGS. 2 and 3.
  • the ring 30 shown in FIG. 2 comprises an annular central portion 46 and a peripheral portion 48 adjacent to the central portion 46.
  • the latter is intended to be inserted elastically into the circular groove 32 of the caseband 10.
  • the ring 30 is slit so as to be elastically deformable under the action of opposing radial forces.
  • Two fingers 50 and 52 secured respectively to the two ends of the central portion 46 extend axially. They are intended to lock the ring 30 angularly in its housing, as described later.
  • the peripheral portion 48 of the ring 30 is formed of an alternation of rigid fingers 54a and notches 56a of varying widths.
  • the ring 30 is made of a material having elastic properties, for example stainless steel or some plastics. When made of stainless steel, it can be made by stamping a plate about 0.4mm thick. Slots 58c and 60c are formed by stamping. Other techniques can be used, for example laser machining.
  • the bezel 18 is shown in bottom view in FIG. 3 without the toothing 38.
  • the projecting circular portion 34 forms a succession of notches 54b and rigid fingers 56b complementary respectively to the fingers 54a and to the notches 56a of the ring 30.
  • two notches 58b and 60b, wide relative to the notches 54b, are complementary to the fingers 58a and 60a having the elastic arms 62a and 64a.
  • These notches 58b and 60b comprise, disposed substantially in their center, two fingers, respectively 62b and 64b, forming push members for cooperating with the flexible arms 62a and 64a.
  • the circular portion 34 is formed by machining the bezel 18, or by stamping and welding to the inner side 20 of the bezel 18.
  • the middle part 10 is shown in perspective, provided with the ring 30.
  • the central portion 46 of the ring 30 is inserted into the groove 32, so that the ring 30 is positioned axially and radially.
  • a recess 66 extending immediately below the groove 32, forms a housing for the fingers 50 and 52, the ring 30 being thus angularly positioned.
  • a mark 68 such as a notch is made on the middle part 10 with reference to the angular position of the ring 30.
  • the ring 30 When the ring 30 is in position in the groove 32, only the peripheral portion 48 of the ring 30 protrudes with respect to the cylindrical portion 24.
  • the fingers 54a and the notches 56a being of complementary shape respectively the notches 54b and the fingers 56b of the bezel 18, it can engage on the middle part 10, in a precise angular position, to be mounted.
  • the mounting of the telescope 18 is shown, partially, in FIG. a mark on the bezel 18 to align with the mark 68, the bezel is positioned in mounting position / disassembly.
  • the notches 54b and the fingers 56b then face respectively fingers 54a and notches 56a.
  • the fingers 62b and 64b are located opposite, respectively, elastic arms 62a and 64a with which they cooperate. Under the effect of a force applied to the bezel 18 axially towards the bottom of the box, the fingers 62b and 64b exert a thrust on the arms 62a and 64a which deform elastically, until the bezel 18 comes in abutment against the bearing surface 28.
  • the width of the fingers 62b and 64b is chosen so that the deformation of the arms 62a and 64a creates a sufficient space for their passage.
  • a slight rotation of the telescope 18 then clears the fingers 62b and 64b and the arms 62a and 64a return in the plane of the ring 30.
  • the bezel 18 is then locked axially with its fingers 56b abutting against the fingers 54a of the ring 30.
  • the ring is locked axially in all its angular positions, even when the fingers 62b and 64b are opposite the elastic arms 62a and 64a, that is to say when the bezel is in the mounting position / disassembly. In this position, it is necessary to exert an axial force to bend the elastic arms and thus release the bezel 18 of the caseband 10.
  • the mounting / disassembling position may be located between two predetermined positions of the detent system 36, provided that the box is provided with it.
  • FIG. 6 shows, in perspective, a disassembly device 70, which comprises a ring 72 and encloses the watch by its middle part 10.
  • the bezel 18 is positioned, with reference to the caseband 10, so that the fingers 62b and 64b are respectively in front of the arms 62a and 64a.
  • the ring 72 comprises two portions hinged in the radial plane, using a hinge 74. It is cooperating with a clamping device 76 for closing it gradually with a clamping wheel 78. Two rigid fingers 80 and 82, each integral with a crown portion 72, extend axially to the level of the telescope 18.
  • the end of these fingers 80 and 82 consists of a spout extending slightly towards the center of the ring 72 and being positioned between the lower face 22 of the bezel 18 and the bearing surface 28 of the middle part 10
  • the bezel 18 and the caseband 10 form a bevel at this interface, so as to guide the beak of the fingers 80 and 82.
  • the tightening of the ring 72 makes the beaks penetrate between the bezel 18 and the caseband 10, which generates an axial force on the bezel 18, tending to separate it from the middle part 10.
  • the fingers 62b and 64b then exert a thrust capable of deforming the elastic arms 62a and 64a.
  • the tool performing the same function could include a vice in which the box is fixed and a clamp clamping the telescope, the clip being slightly axially displaced, and then turned with reference to the vice, to allow the fingers to disengage from the arms.
  • the device 70 will then comprise advantageously a positioning member bringing the bezel 18 into a position in which arms and fingers are facing each other before the axial force is exerted on the bezel 18.
  • the flexible arms 62a and 64a which form elastic members
  • the fingers 62b and 64b which form push members cooperating with these arms
  • the thrust members and the elastic members could be three, four or more, without the operation of the bezel is changed.
  • the fact of having fingers and arms staggered in the rest positions defined by the latching ensures perfect retention.
  • using a device allowing an angular offset at the time of tightening allows to bring fingers and arms facing each other at the time of disassembly only.
  • a ring 30 comprising flexible arms 62a and 64a is rigidly mounted on the middle part 10.
  • the ring 30 could be mounted on the inner side 20 of the bezel 18, in a groove made for this purpose.
  • the protruding circular portion 34 would be integral with the middle part 10. The operation of the bezel 18, its mounting and dismounting would be unchanged.
  • the embodiment of the ring 30 and the circular portion 34 would be identical.
  • the ring 30, which constitutes an insert mounted rigidly on the middle part 10 or the bezel 18, may be an integral part of the middle part 10 or the bezel 18, while retaining the same function. In this case, it is performed by machining the cylindrical portion 24 or the inner side 20.
  • the flexible arms 62a and 64a are formed by stamping a metal plate and welding to the machined portion.
