Definitions

  • the present invention relates to a timepiece such as, in particular, a wristwatch, comprising a middle and a bezel capable of rotating on the middle part, a seal being inserted between the bezel and said middle part.
  • a watch of the above kind is known from the patent application European EP 1 420 307 on behalf of the Swiss company Eterna.
  • This watch has a middle and a bezel mounted mobile in rotation on the middle part.
  • the middle and the bezel define between them an annular chamber and a gap open towards the outside of the box.
  • a seal, inserted between the bezel and the middle part, is arranged in the chamber.
  • This seal comprises an annular ring of material of strongly elastically deformable type and whose section comprises two lips, one resting against the bezel and the other bearing against the middle part.
  • a compression member is disposed in the chamber, on the side of the gap, interposed between and cooperating with the lips to press respectively against the bezel and against the middle part.
  • the compression member consists of an annular spring which is in the form of a band of substantially constant width forming regular undulations arranged on either side of a circle whose diameter is substantially equal to the median diameter. from the room.
  • the corrugations are folded V on either side of the line constituting the diameter of the spring.
  • the angle formed by the corrugations is slightly greater than that formed by the lips so that, when the spring is put in place, it forces the free ends of the lips against the walls of the chamber.
  • the annular spring is in contact with the lips of the seal by the top of the V-shaped folds. It is at these folds that the pressure exerted by the spring on the seal is the strongest.
  • the spring bends come to bite the seal and sink into the material of which is made this seal, which irreparably alters the sealing qualities thereof .
  • the seal generally has the shape of an open U on the side of the gap which communicates the annular chamber with the external medium.
  • the water compresses the seal and applies the lips against the walls of the chamber. It has been realized that such an arrangement in which the water enters the seal because it is open on the gap side does not provide an optimum seal.
  • all kinds of solid elements are likely to be housed between the lips of the U-shaped seal and seize the rotating telescope mechanism.
  • the present invention aims to remedy the aforementioned problems as well as others by providing a timepiece comprising a rotating bezel whose operation is particularly more reliable.
  • the present invention relates to a timepiece comprising a rotating bezel and a middle part, the rotating bezel being rotatable relative to the middle part, said bezel and said middle part defining between them an annular chamber in communication with the body. outside via a gap, a lip seal having a U-shaped profile being disposed in the chamber so as to seal the assembly formed by the bezel and the middle part, and a body of compression exerting on the lips a compressive force under the effect of which said lips are respectively pressed against the bezel and against the middle part being housed inside the joint, the timepiece being characterized in that the compression member presents a smooth outer surface.
  • the present invention provides a compression member whose compression force is no longer transmitted along the contact points only to the seal.
  • the compression member no longer hurts the seal, which ensures a high level of sealing throughout the life of the watch.
  • the compression member is an O-ring type seal.
  • the compression ratio of the seal can be freely adapted by adjusting the Shore hardness or O-ring seal section.
  • the base of the seal which constitutes an intermediate part connecting the lips of said seal is located on the side of the gap so that the free lip acts as a wedge in case of overpressure of water.
  • a lip seal is conventionally constituted by a steel frame on which has been molded a U-shaped elastomer part. The outer part of the seal comes to seal in the chamber, while the inner part has a lip which comes into contact with the compression member.
  • the present invention proceeds from the general inventive idea of housing in a profiled gasket a compression member having a smooth outer surface, so as to prevent contact between the compression member and the gasket being made. as a finite number of points, which would lead to seal degradation and leakage.
  • the watch case according to the invention comprises a bottom 2 and an assembly formed by a middle part 4 and a bezel 6 rotatably mounted on the middle part 4.
  • the middle part 4 and the bottom 2 define a volume in which are housed the various organs of the watch (not shown in the drawing).
  • a glass 8 is fixed on the bezel 6 with the interposition of a seal 10 between the glass 8 and said bezel 6.
  • the middle part 4 has in its middle part a flange 12 which extends towards the center of the box and under which is slid a corresponding flange 14 formed on the outer periphery of a ring 16 arranged on the side Inside the caseband 4.
  • the ring 16 could be omitted.
  • On the upper face of the flange 12 of the caseband 4 is a second ring18 which has at its upper end a flange 20 which bears on a shoulder 22 provided at the base of the rotating bezel 6.
  • a flat gasket 24 serving sliding shoe is disposed between the flange 20 of the ring 18 and the shoulder 22 of the bezel 6.
  • the middle part 4 and the bezel 6 When the assembly formed by the two rings 16 and 18, the middle part 4 and the bezel 6 is assembled, it is possible to fix the bottom 2 of the watch case 1 on the caseband 4, for example by means of screws 30, one of which only one is represented in the drawing. Other known closure systems such as a wireless seal, a ball lock or screwing the bottom 2 on the middle 4 can also be envisaged. Conventionally, a seal 32 is disposed between the bottom 2 and the middle part 4.
  • a second flat seal 34 acting as a sliding shoe is disposed in a gap 36 between the rotating bezel 6 and the middle part 4.
  • This seal also ensures a certain sealing of an annular chamber 38 communicating with the gap 36 and defined by the bezel 6 and the middle 4.
  • This annular chamber 38 has two side walls 38a and 38b respectively formed by the bezel 6 and the middle part 4, a wall upper 38c formed by the bezel 6 and a bottom wall 38d essentially formed by the middle part 4.
  • a seal 40 having a U-shaped profile is disposed in the annular chamber 38 so as to seal the watch case 1 according to the invention.
  • This seal has two lips 40a and 40b respectively bearing against the walls 38a and 38b and interconnected by an intermediate portion 40c which constitutes the base of the seal 40.
  • the base 40c of the seal 40 is in abutment against the upper wall 38c of the annular chamber 38.
  • the seal 40 opens downwards, opposite the gap 36 through which the chamber 38 communicates with the outside .
  • the free lip 40b is wedge effect in case of water overpressure, which ensures a reinforced seal of the watch case 1 according to the invention.
  • a compression member 42 such as an O-ring type seal.
  • the compression member 42 presses the lips 40a and 40b of the seal 40 respectively against the side walls 38a and 38b of the annular chamber 38.
  • the compression ratio of the seal 40 can be freely adapted by adjusting the Shore hardness or the section of the compression member 42.
  • the compression ratio of the seal 40 also determines the rotational torque of the bezel 6.
  • the outer surface or envelope of the compression member 42 is smooth, free from any projecting element, so that said compression member 42 does not risk injuring the seal 40.
  • the seal 40 is respectively shown in section and in perspective in FIGS. 2 and 3.
  • FIG. 1 it is represented in the rest position in phantom and solid lines in a compressed position in the annular chamber 38.
  • the lip 40a of the seal 40 in the compressed position, is partially bent under the compression member 42.
  • the lip 40b of the same seal 40 presents at its free end a return 44. In this way, any risk that the compression member 42 may fall under the effect of gravity is avoided.
  • any type of compression member may be provided provided that its outer surface is smooth and does not risk injuring the seal sealing.
  • the seal may be made of any material having a low coefficient of friction and a non-stick surface such as polytetrafluoroethylene better known under its acronym PTFE.
