Definitions

  • the present invention relates on the one hand to a timepiece with glass or watertight rotary glass-bezel assembly, of simplified construction, using a connection joint disposed between the fixed part and the rotary part; and on the other hand, the connecting joint making it possible to produce said timepiece.
  • Watches with known waterproof rotating glass have a large number of parts and their construction is complex.
  • Patent CH 681 127 (Werthanor SA) represents a typical example of the type of construction used to obtain an effective seal.
  • a traditional seal is placed between the bezel and the middle part, a casing circle placed inside the middle part makes it possible to fix the assembly.
  • the best known way to simplify a construction of this type and / or to make a thinner watch, is to eliminate the seal, with all the drawbacks that this entails.
  • This timepiece has the characteristics described in claims 1 to 19, and is produced by means of a conforming joint seal. to claims 20 to 24.
  • the present invention makes it possible to obtain a watch with watertight rotating glass, the construction of which is considerably simplified, since only a connecting joint and possibly a fixing means, disposed at the middle / bezel interface, are sufficient to allow rotation and sealing.
  • a particular embodiment even allows the use of either a glued or welded glass / bezel assembly or even a one-piece glass-bezel, which further simplifies the construction of the watch.
  • the present invention therefore makes it possible to have a glass edge to edge, offering the possibility of mounting from the top, and thus to have a monocoque bottom.
  • a glass of various shapes for example curved or not.
  • edge-to-edge lens with the signs usually arranged on the bezel similar functions are obtained with improved reading characteristics and precision.
  • the edge-to-edge rotating glass offers multiple possibilities for functions such as the diving watch, slide rule, etc.
  • the reading and function signs can be placed directly on the glass, on a plate, dial or flange under the glass, on a decorative bezel, etc.
  • the simplified design and the optimization of the number of parts make it possible to produce thinner cases compared to known waterproof watches.
  • the present invention thanks to the presence of the connection joint, makes it possible to protect the internal parts against corrosion, deterioration or other form of wear, by preventing any liquid or solid contaminant (particles, dust, etc.) from entering the housing.
  • the means for locking the telescope (notches, ratchets or the like) is thus well protected.
  • the watch according to the invention comprises a glass 1 of standard type, such as, for example, mineral glass, plexiglass, sapphire, or other transparent material, fixed to the bezel 30 by means of a seal 3 disposed between the periphery of the glass and a bearing face 35 of the bezel.
  • a portion 34 of the bezel enters a recess 5 formed on the top of the middle part 4, at the periphery of the latter.
  • this fixing can be of the removable or permanent type.
  • the fastening means 20 is preferably arranged along the internal face 31 of the telescope, as shown in FIG. 1. However, it may prove to be just as advantageous that the latter be disposed along the external face. 32 of the telescope, depending on the space available on one or the other of these faces.
  • connection joint 10 is disposed in a groove 33 formed in the external face 32 of the telescope 30.
  • the joint is shaped so that an active portion 11 is prominent on the external face 32.
  • This joint can be made of different materials , but should preferably be flexible enough to allow good positioning of the active portion 11 and the rotational movement between the bezel 30 and the middle part 4; it must also be rigid enough to offer good support between these two same parts. Conclusive tests have been carried out with connection joints 10 manufactured in "NBR 75". Any other material meeting these criteria, in particular elastomers, can also be used, with different hardness coefficients.
  • the active portion 11 is kept in tight fit by the adjacent wall 2 of the middle part. This adjustment makes it possible to produce a watertight seal between the rotating part and the fixed part of the watch.
  • a recess 12 which can take a multitude of forms, is formed in the adjacent wall 2 to serve as an active female portion.
  • the active male portion 11 of the seal 10 penetrates in whole or in part into said recess, in order to perfect the seal thanks to a larger contact surface while providing more effective support.
  • the connecting joint can take a multitude of forms, be mounted according to a multitude of orientations and be fixed either on the bezel, on the middle part or on the glass.
  • the fixing means can be integrated into the connection joint, further simplifying construction and assembly.
  • This joint also offers the advantage of being able to be used with different materials, such as steel, brass, plastics, precious metals, etc. It can be fixed in a housing by clamping, be glued, vulcanized, welded, etc. By varying the shape and more particularly the width of the active portion 11 as well as the tightening rate of the tight fit, it is possible to optimize certain mechanical characteristics such as the friction, and thereby, optimize the force necessary to rotate the glass and / or the bezel.
  • the watch described above is therefore fully waterproof, positively and negatively: an overpressure external to the case caused by a high pressure of air or liquid has no effect on the inside of it, the internal and external pressures remaining substantially the same and the environments remaining distinct; similarly, in the event of a vacuum outside the housing, such as at altitude, the internal pressure remains substantially unchanged.
  • the seal is ensured regardless of the angular position of the bezel and / or the glass with respect to the middle part.
  • the presence of the connecting seal 10 allows a substantially vertical movement between the bezel 30 and the middle part 4, with or without rotation of the bezel, these two movements can be entirely independent of each other.
  • the force exerted by the external pressure possibly combined with a slight vertical displacement, gives the active portion 11 an optimal positioning so that the seal increases as the pressure increases.
  • This phenomenon allows a connection joint of the type illustrated in FIG. 2d to reach sealing levels greater than 5 atmospheres.
  • FIG. 2 illustrates various advantageous profiles for the connecting joint 10.
  • a simple active portion from 2e to 2i, two active portions, one of which exerts its effect on the lower wall of the recess 5, making it possible to offer increased protection against any infiltration into the housing.
  • the active portion exerting its effect on the bottom wall of the recess 5 can be used both to absorb the vertical play between the fixed part and the rotating part of the watch while acting on the level of water resistance, in particular to prevent decompression of the case when the watch is located in a low pressure environment.
  • Figure 3 illustrates this second embodiment.
  • the elements which are of the same nature and play the same role as corresponding elements of Figure 1 are designated by the same reference signs.
  • the bezel 30 is held by a fastening means 20 disposed on the side of the external face 32 of the penetrating portion 34 of the bezel 30.
  • the fastening means 20 is maintained by a fixing ring 21 disposed in the connecting joint 10.
  • Said means 20 is preferably a wire spring with known types of sides, but may also be different, as shown in FIG. 6, where a rod partially arranged in the seal 10 ensures the maintenance.
  • the fixing means 20 preferably comprises a portion which penetrates into a groove in the adjacent wall, thus ensuring the maintenance in the vertical direction.
  • the fixing ring 20 illustrated in FIG. 3 is preferably a steel ring placed in gasket. This ring can obviously be made of another rigid material, such as for example a composite based on carbon fibers, or the like. Thanks to the integration of the holding means in the joint, the construction of the bezel 30, as well as its assembly in the middle part, are simplified.
  • FIG. 3 also shows an example of a seal 10 with two active portions. The tight adjustments, both in the lateral and vertical directions, ensure uniform contact between the joint and the concomitant surface over the entire periphery.
  • the glass 1 / bezel 30 assembly is replaced by a one-piece glass, a portion of which is shaped like a bezel ( Figures 4 and 6), or by a glass s' extending over the entire upper part of the watch with a portion of glass, steel, titanium or other bezel glued or welded under the underside of the glass ( Figures 5 and 7a).
  • the watch according to the invention may comprise a locking means making it possible to maintain the glass and / or the bezel in a pre-established position.
  • These means are known and include, for example mechanisms with notches, toothing, ratchets, etc., arranged for example under the bezel.
  • FIGs 7a and 7b illustrate an example of a watch according to the present invention.
  • Glass 1 includes the inscriptions 1a (numbers, marks, etc.) usually written on the bezel.
  • the inscriptions on the glass can be made by any known means, for example by metallization.
  • the edge-to-edge glass is glued to the bezel 30.
  • the dial 6 includes a raised portion at the edge thereof, on which the index points and other marks selected according to the type of watch are arranged.
  • the glass is easily angularly moved thanks to the lugs 7 arranged around the periphery.
  • the pins can obviously be replaced by a groove made directly in the glass.
  • Figure 8 shows a third embodiment where the glass edge to edge 1 is folded over the outer sides of the middle part 4 so as to form a cover.
  • the seal 10 fixed to the internal wall of the glass, enters an external fixing groove 9 formed on the periphery of the middle part 4, so as to maintain and rotate the glass, as well as the seal of the assembly.
  • Figure 9 shows a fourth embodiment of the present invention, where the dial 6 rotates with the glass 1 and the bezel 30.
  • the dial 6 is disposed on a flat part of the rotating bezel 30.
  • the closure is made from above , by means of the glass 1, fixed to the bezel 30 by means of an attached bezel 36, arranged in leaktight manner on the bezel 30.
  • This embodiment is particularly advantageous since it makes it possible to produce a multitude of combinations where the inscriptions and indexes can be placed on the glass and / or on the dial and / or on the middle part.
