Definitions

  • the present invention relates to watches provided with a rotating bezel.
  • the rotating bezel of a watch makes it possible to mark a point in time which serves as a point of reference for the duration of a sporting or other activity.
  • a point in time which serves as a point of reference for the duration of a sporting or other activity.
  • Various locking systems have been developed, which are generally complex and expensive to manufacture, or which do not guarantee secure locking of the telescope.
  • the present invention aims to provide a locking system for the bezel of a watch, which is simple and which guarantees locking in all circumstances.
  • a watch case provided with said system is described in the appended claims.
  • the invention relates to a watch whose case includes a middle part and a rotating bezel, provided with a bezel locking system.
  • the system comprises a rotary crown which is integral with an axis, the latter being arranged in a radial hole formed in the middle part. By turning the crown, the user can screw or unscrew the axis relative to the hole.
  • the axis comprises a frustoconical section which interacts with a pin mounted perpendicular to the axis, and returned to the axis by a spring. By screwing the axis into the hole, the tapered section will push the pin into a receiving space provided on the lower surface of the telescope, which will lock the telescope. Unscrewing the axis automatically releases the pin from the receiving space thanks to the return force exerted by the spring.
  • the indications 'lower' and 'upper' describe the position of elements of a watch case when it is held horizontally, with the means for indicating the time facing upwards.
  • the figure 1 represents a middle part 2 of a watch case according to an embodiment of the invention.
  • a rotating bezel 3 is mounted on the upper surface of the middle part 2.
  • the internal components such as a dial with hands, a digital index and the internal mechanism are not shown. These components do not form the subject of the invention and they can be produced by known methods and technologies.
  • the middle part 2 is provided with horns 4 for fixing the strands of a bracelet. On the plan view looking figure 2 , we see the classic crown 5 for adjusting the watch hands.
  • the middle part 2 is provided with an additional crown 6 which is part of the locking system of the rotating bezel 3 according to the invention.
  • the locking ring 6 is shown in section, in the unlocked position of the system.
  • the bezel 3 is rotatably retained on the middle part 2 by a polygonal spring 30 housed in a pair of lateral grooves provided respectively in the bezel and in the middle part.
  • a first element of the locking system is formed by a radial hole 7 in the middle part 2, in which a tube 8 is fixedly mounted.
  • the tube 8 can for example be driven out, glued or screwed into the middle part 2.
  • a part of the tube 8 protrudes from the external lateral wall of the middle part 2.
  • the tube 8 is provided with an internal thread, the thread extending at the less over the length of the part which protrudes from the middle part 2 and is intended to cooperate with a corresponding thread of the locking crown 6.
  • the locking ring 6 is integral with an axis 9 whose different portions are visible to figures 3 and 4 , as well as figure 5 which represents a 3D view of the axis.
  • the axis 9 comprises a threaded section 10, the outside threading of said section corresponding to the internal thread provided in the tube 8.
  • the threaded section 10 is located inside the crown 6, on the internal surface of a circular groove 19 which extends in the body of the crown 6.
  • the threaded section 10 is followed by a first cylindrical section 11 (non-threaded), a frustoconical section 12 and a second cylindrical section 13 which is terminated by a flange 14.
  • the frustoconical section 12 decreases the diameter of the axis continuously between the diameters of the first and second cylindrical section 11 and 13.
  • the diameter of the flange 14 corresponds to the internal diameter of the tube 8, so that the flange 14 can slide relative to the tube 8.
  • the underside of the telescope 3 comprises a plurality of axial holes 15 distributed regularly over the periphery of the telescope.
  • the middle part 2 is provided with a hole 20 which is oriented perpendicular to the axis 9, and in which a pin 21 is mounted, so that said pin 21 slides relative to the hole 20 and interacts with the axis 9.
  • the central axes of the pin 21 and the locking axis 9 are perpendicular to each other and intersect at a point.
  • the pin 21 is biased towards the axis 9 by a spring 22, so as to maintain physical contact between the lower end of the pin 21 and the surface of the axis 9.
  • the crown 6 is completely unscrewed ( figure 3 )
  • the pin 21 is in contact with the minimum diameter section 13 and with the flange 14. In this position, the upper end of the pin 21 is not housed in any of the axial holes 15 of the bezel 3.
  • the bezel 3 is then free and can be rotated by the user.
  • the user can then insert the axis 9 into the tube 8 by screwing the threaded section 10 into the tube.
  • the movement of the axis 9 will gradually push the pin 21 into one of the axial holes 15 of the telescope, by the interaction between the pin 21 and the slope of the frustoconical section 12, and this against the prestressing force exerted by the spring 22.
  • the lower end of the pin 21 is in contact with the first cylindrical section 11 and the upper end of the pin 21 is housed in the hole 15, which makes it possible to obtain a secure locking of the telescope which cannot be accidentally released.
  • the part of the tube which protrudes from the wall of the middle part has entered the circular groove 19.
  • the user unscrews the crown 6 towards the configuration of the figure 3 .
  • the spring 22 lowers the pin 21 until the pin is completely out of the hole 15, resulting in the release of the telescope.
  • the pin 21 is slidably arranged in a block 23 mounted in the hole 20 and comprising seals 24.
  • the tube 8 may include a portion 25 having a diameter greater than that of the rest of the tube, said portion 25 being mounted to abut against the outer lateral wall of the middle part 2.
  • the crown 6 of its side is provided with a seal 26 between the body of the crown and the outer surface of the tube 8. The seal 26 will be pushed against the portion of larger diameter 25 when the crown 6 reaches its locking position. The seal 26 will not only have a sealing effect but it will also ensure a fixed closure thanks to its compression between the crown 6 and the portion with a larger diameter 25.
  • a helium valve 29 is integrated into the crown and more precisely inside the axis 9.
  • the valve is arranged coaxially with the axis 9. It has a body 30 prestressed by a spring 31.
  • the body 30 comprises at its inner end a surface 32 which is subjected to the pressure prevailing inside the middle part 2. From a predefined threshold, the pressure will overcome the force of prestress exerted by the spring 31, resulting in the depressurization of the interior of the middle part 2.
  • One or more seals 34 and 35 are mounted between the body of the valve 30 and the internal surface of the axis 9.
  • valves in diving watches are known per se and the invention is not limited to the embodiment shown in the figures, but it also includes embodiments which do not include a valve inside axis 9, or which include a valve mounted elsewhere on the middle part 2.
  • the function of the valve is to release the gases infiltrated into the watch during a saturation dive. When going up, the pressure created by these gases, generally Helium, can damage the watch.
  • the groove 19 between the body of the crown 6 and the axis 9 in cooperation with the part of the tube 8 which protrudes from the middle part 2 results in a robust structure having good sealing properties.
  • other forms of crowns integral with an axis are conceivable.
  • said first and second cylindrical sections are not essential: the extreme positions of the pin 21 relative to the section frustoconical 12 can be on said frustoconical section itself.
  • the axis 9 can be arranged directly in a threaded hole in the middle part 2 rather than in a tube 8 mounted in the middle part.
  • the holes 15 are only examples of receiving spaces capable of receiving the end of the pin 21.
  • the bezel 3 could include an axial toothing on its lower surface, with the recesses between two teeth forming a receiving space for the pin 21.
  • the end of the pin 21 is preferably machined so that the shape of said end corresponds to the shape of the recesses.
