Definitions

  • the present invention relates to the field of waterproof watch cases. It relates more particularly to a box with a rotating bezel, type of those commonly used in scuba diving watches.
  • the rotating bezel provides a marker next to the hands, specially to define a maximum dive time.
  • the present invention aims to overcome these drawbacks by providing a watch case fitted with a flexible rotating rotating bezel and the seal remains good, even at high pressures.
  • the invention relates to a watch case comprising a middle, a bezel mounted mobile in rotation on the middle and defining between they an annular chamber and a gap open towards the outside of the box, a glass tightly mounted on the bezel, an interposed gasket between the bezel and the middle part and arranged in said chamber.
  • the lips are connected to each other by an intermediate part. They are arranged so as to form an acute angle between them.
  • the room is defined by side walls, upper and lower.
  • the lips present, on the side from their free end, a contact surface intended to be supported on the side walls of the chamber, while the intermediate part is flat and marries the bottom wall of the room. So that the seal can be assured, it is necessary that the gap is not closed.
  • the compression member comprises an annular spring placed directly at the lip contact.
  • this spring has regular undulations, distributed on either side of a circle of diameter substantially equal to the median diameter of the chamber, the corrugations being folded by the line formed by the middle circle, the angle of the fold being slightly greater than or equal to that formed by the lips.
  • This spring can advantageously be made of stainless steel.
  • the compression member may, in addition, include a ring positioning interposed between the spring and one of the walls of the chamber. She is advantageously arranged opposite the telescope and has studs positioning based on it so as to maintain the intermediate part resting against a wall of the chamber.
  • the invention also relates to a watch seal. advantageously, it has an annular ring made of material of the strongly elastically deformable, the section of which has two lips, and a member compression arranged between the lips and cooperating with them to compress.
  • the compression member comprises an annular spring placed directly in contact with the lips and a cooperating positioning ring with the spring to hold it in place.
  • the base 20 is fixed to the middle part 16, generally by screwing or by any means known to those skilled in the art, a seal being interposed between them.
  • the middle part 16 has a structure arranged so as to ensuring the mounting of a watch movement. It also includes a flat surface 24 and a cylindrical surface 26 ensuring the positioning of a flange 28.
  • the flange 28 is fixed to the middle by screws, schematically shown by an axis line 30. It ensures the positioning and guiding of the telescope 18, thus allowing it to rotate on the middle 16.
  • the glass 22 can be fixed to the bezel 18 by gluing or by chasing with interposition of a seal, or by any means known to those skilled in the art.
  • the middle part 16 and the bezel 18 are shaped so as to define a chamber annular 36 having two side walls 36a and 36b, respectively formed by the middle part 16 and the bezel 18, an upper wall 36c formed by the bezel 18 and a bottom wall 36d essentially formed by the middle part 16.
  • the chamber 36 is connected to the outside of the box 10 by a gap 40.
  • the chamber 36 serves as a housing for a seal 42, comprising a ring 44 with two lips 44a, advantageously in polyurethane of hardness on the order of 20 to 30 Shore A and a compression 46.
  • the ring 44 is annular and its section has an overall shape of U.
  • the branch bottom of the U constitutes an intermediate part 44b connecting the two lips 44a.
  • the width of the U, at its base, is less than that of the chamber 36, while the lips 44a, constituting the lateral branches of the U, form between them a acute angle of the order of 5 ° to 15 °. They have, on the side of their end free, a contact surface intended to be supported on the walls of the chamber, leaving the gap 40 free.
  • These contact surfaces between the lips 44a and the side walls 36a and 36b of the chamber 36 are continuous, such that so that they seal the interface between the middle part 16 and the bezel 18.
  • the intermediate part 44b is flat and follows the bottom wall 36d of the room 36.
  • a space 48 defined between the branches of the U is thus in direct communication with the outside of the watch case 10 by through the gap 40.
  • the compression member 46 Inside the space 48 is housed the compression member 46. It is constituted an annular spring 50 placed directly in contact with the lips 44a and a positioning ring 52 interposed between the spring and the upper wall 36c from room 36.
  • the annular spring 50 is in the form of a strip of substantially constant width forming regular undulations arranged on either side of a circle of diameter D substantially equal to the median diameter of the chamber 36
  • the spring 50 is obtained from a chemically machined stainless steel blade.
  • the undulations are folded in V on either side of the line constituting the diameter D.
  • the angle formed is slightly greater than that formed by the lips 44a, in such a way that, when it is put in place, it constrains the free ends of the lips 44a against the walls 36a and 36b of the chamber.
  • This angle is typically between 10 ° and 20 °. Its top is rounded. he results from this conformation that the spring 50 has a high elasticity.
  • the pressure applied by the spring 50 on the ring 44 makes it possible to control the torque necessary for the rotation of the telescope 18 and to ensure the contact of the lips 44a over the entire periphery of the walls 36a and 36b.
  • the positioning ring 52 shown in FIGS. 4a and 4b, has the same median diameter as the ring 44. It is arranged in contact with the spring 50, opposite the telescope 18 and has positioning pads 58 pressing on the bezel 18 so as to keep the spring 50 in contact with the lips.
  • the pads 58 are cylindrical in shape and have a flat surface, intended to be in contact with the telescope.
  • the height of the assembly formed by the ring 52 and by the studs 58 is equal to the distance separating the bezel 18 from the spring annular 50. This is thus precisely held in place while the bezel 18 slides on the pads 58 when it is turned.
  • the chamber 48 When the watch is submerged, the chamber 48 is connected to the outside environment by the gap 40 and, thanks to the fact that the positioning pads 58 do not occupy the entire chamber 48, the latter is at the same pressure as the external medium.
  • the water then compresses the positioning ring 52 which presses on the seal 42 and strongly applies the lips 44a against the walls of the chamber 36.
  • the stronger the external pressure the stronger the lips 44a applied against the walls 36a and 36b of the chamber.
  • the friction forces then created between the lips 44a and the watch case 10 make it impossible to rotate the bezel 18. There is therefore locking in diving, which increases safety.
  • the diver breathes a gas mixture containing helium or hydrogen. These light gases can get inside the watch case. When ascending to the surface, the external pressure may decrease faster than that prevailing inside the watch case. If a valve is not provided to regulate this overpressure, the glass can be evicted from his home. With a box according to the invention, such a valve is not not necessary. Indeed, thanks to the shape of the lips 44a, the gas contained in the inside of the box 10 can escape freely.
  • the watch case thus produced is perfectly waterproof when the outside pressure is higher than the inside pressure and it leaves escape the gas it contains when the internal pressure is higher than external pressure.
  • So room 36 could have a section other than rectangular.
  • the seal could be oriented in a different way, with, for example, the lips in contact with the upper walls 36c and lower 36d, while the intermediate part would be contact with the side wall 36a formed on the bezel 18.
  • the means of assembling the bezel 18 on the middle part 16 could also be considerably changed.
  • the movable interior part could occupy a much more space, to allow the display of a maximum information and thus provide better reading conditions.
