Definitions

  • the present invention relates to the field of watchmaking. It relates to a watch which has a movement and which has a transmission device between an external control member and a movement mechanism.
  • the mechanisms of movement are placed opposite the pushers which actuate them so that the architecture of the movements and the arrangement of the external control members are directly related.
  • the difficulty of designing a movement and adding additional functions is the cause of some similarities in the many horological achievements.
  • the push buttons operating a chronograph are for example very often located at two and four hours, on either side of the control rod.
  • This watch has a complex transmission system composed of rods and flip-flops mounted between the movement and the middle part that positions the two push buttons operating the chronograph on the opposite side of the control rod while maintaining a conventional movement.
  • this type of mechanism has several disadvantages: it is complex to design, expensive to manufacture, bulky, heavy and the additional friction it causes increase the effort required for the actuation of the control pushers.
  • the present invention aims to overcome the aforementioned drawbacks of the prior art by proposing a new type of control device for watches and to offer new aesthetic and technical possibilities to designers of watches and movements.
  • the invention relates to a watch comprising a box having a middle part in which is housed a movement.
  • the watch also comprises a control member intended to be actuated by a user as well as an internal transmission device provided with an actuator able to move, in response to the actuation of the control member, between a position of rest and an active position in which it activates a movement mechanism.
  • the transmission device comprises a closed cavity filled with a fluid and a thrust means kinematically connected to the control member and arranged to move the fluid in the cavity, the displacement of the fluid in the cavity causing the displacement of the actuator.
  • Such a construction has the advantage of decorrelating the position of the control member from that of the mechanism it actuates in the movement. This allows placing the controls at the desired locations on the box according to only aesthetic and ergonomic criteria but also to design movements without being constrained by these same criteria.
  • the figure 1 represents a first embodiment of a watch according to the invention which only appear details useful for understanding the technical problem.
  • This watch comprises a box whose caseband 1 is shown in section and a movement 2 located in the center of the caseband 1.
  • a control member intended to be actuated by a user appears in the form of a pushbutton 3 s' extending outside the caseband 1.
  • An internal transmission device is housed in the caseband 1.
  • This device comprises a closed cavity filled with a preferably incompressible fluid.
  • the cavity comprises a hose 4 whose first end opens into a control piston chamber 5 and whose second end opens into an actuator piston chamber 6.
  • the transmission device further comprises a thrust means capable of displacing the piston. fluid in the cavity.
  • the thrusting means is a control piston 7 kinematically connected to the pusher 3 and opening into the cavity at the level of the control piston chamber 5.
  • the actuation of the pusher 3 causes the piston of the piston to move. control 7 in the control chamber 5 and the displacement of the fluid in the cavity.
  • the transmission device further comprises an actuator disposed inside the middle part vis-à-vis a mechanism 8 of the movement that it is intended to activate by moving from a rest position to an active position .
  • the actuator comprises an actuator piston 9 opening into the actuator piston chamber 6 and arranged to move and actuate the mechanism under the effect of the thrust of the fluid.
  • the hose 4 is housed for example in a groove 10 formed in the inner face of the caseband 1.
  • the transmission device is reversible, that is to say that a return force exerted by the mechanism 8 on the actuator, tending to return it to its rest position, causes the displacement of the actuator piston 9, the recoil of the fluid in the cavity and pushes the control piston 7 and the pusher 3 in their original position once the latter released.
  • the transmission device may also comprise additional return means, independently of the mechanism of the movement. This return means may take the form of a spring acting for example at the control member or the actuator.
  • the hose 4 connecting the chamber of the control piston 5 to that 6 of the actuator can be formed directly in the caseband 1 or by means of machining or engraving or selective engraving such as that described in the patent application EP No 2795410 incorporated herein by reference, either by a three-dimensional printing technique or by the assembly of two pieces machined separately and forming a duct once assembled.
  • the method of manufacturing by three-dimensional printing makes it possible, in the mass of the caseband 1, a complex network of conduits and housings for receiving actuators and control members.
  • the cavity is at least partially made in the mass of the caseband 1.
  • a piston system moving in the cavity or a deformable system it is the displacement of a first wall of the cavity kinematically connected to the control member which causes the displacement of the fluid in the cavity.
  • the moving wall is located directly on the piston.
  • the displacement of the fluid in the cavity causes the displacement of a second wall of the cavity kinematically related to the actuator.
  • the first and second walls of the cavity are kinematically connected to each other and the control member is kinematically connected to the actuator. It is of course possible to combine all types of thrust means or actuator between them they are piston or deformable.
  • the transmission device makes it possible to vary the triggering force and the race independently of the mechanism. It suffices to adapt the ratio between the fluid sections displaced at the thrust means and the actuator. In a transmission device using pistons, this amounts to choosing control pistons 7 and actuator 9 of different diameter. It is for example possible to reduce the force to be applied on the control member relative to that required to activate the mechanism, increasing its stroke. In the same way, it is possible to obtain a longer actuator stroke by increasing the force to be provided on the control member.
  • the actuators have been placed in the middle part of the body so as to activate the movement mechanisms in a radial direction with reference to the center of the movement. It is obvious that the actuators could be arranged differently and exert effort in any direction. The actuators could also be placed in other places of the box, on the bottom or directly in the movement closer to the mechanisms they operate.
  • the hose to transmit the thrust force of the control member to the actuator could walk on the surface or inside the component parts of the box, or the movement, such as the bottom, the container or the plate, or be directly dug in these parts by means of rapid prototyping, machining or etching for example chemical.
  • the great freedom of positioning and orientation of the actuators simplifies the design of movements.
  • the movements of the actuators are linear and their stroke can easily be adapted to the needs of the mechanism, which makes it possible to dispense with certain transmission latches or to reduce their size.
  • the space thus released can be used to integrate additional complications or functions or to reduce the volume of the watch.
  • the telescope may constitute a discrete control member by rotation.
  • a cam located on an inner face of the bezel allows, according to its angular position, to actuate one or more thrust means acting as a cam follower.
  • the ability to vary the triggering force of the control members also makes it possible to use, for the same mechanism, pushers of different sizes for which the pressure felt by the user, that is to say the applied force divided by the surface of the pusher, will be substantially identical.
  • the transmission device of the present invention makes it possible to perform a non-linear function between the displacement of the control member and that of the actuator.
  • a deformable part 13 which, instead of being cylindrical as on the Figures 3 and 4 , would present a variable section such as a sphere, a cone or any other form of revolution of variable section.
  • the use of appropriate profiles makes it possible to erase this type of disparities by smoothing the curve of the effort felt at level of the control member. This particular arrangement makes it possible to improve the ergonomics of the control members and the quality perceived by the users.
  • the transmission device may comprise an adjusting device adapted to adjust the activation threshold of the mechanism by the actuator in response to the actuation of the control member.
  • the adjustment device may, for example, be designed to finely adjust the length of the piston of the control member or the actuator. It can also be located at the level of the cavity or section of the hose in which it can be provided that a deformable zone is more or less compressed by the displacement of a screw, an eccentric or any other equivalent device which will have the effect of slightly moving the actuator in one direction or the other.
  • the watch may comprise a plurality of actuators, arranged in parallel at two ends of the same cavity and able to move in a synchronized manner in response to the displacement of the same organ. ordered.
  • the watch according to the invention provides the designer with a simple solution for solving synchronization problems within the movements.
