Definitions

  • the present invention describes a time indicator with mechanical regulator according to the definition of the claims. This time indicator is particularly suitable for use in wristwatches.
  • the present invention belongs to the family of so-called “vortex” time indicators.
  • the classic type of such a time indicator is represented by the “Bréguet tourbillon” from 1795.
  • a balance, its spiral spring and its escapement are assembled inside a rotating cage, the speed of rotation of the cage is one turn per 60 sec.
  • the cage rotates around a double bearing gear.
  • Patent GB-21,421 of 1892 shows a cantilevered “tourbillon” in a single wide bearing.
  • Patent CH-353,679 of 1961 shows a cantilevered bearing construction with ball bearings where the ball bearing replaces the thick plain bearing used until then.
  • cantilevered ball bearing bearings are widely used, as examples in constructions according to patent US-4,132,061 of 1977.
  • the rotation speed can be lower by 60 sec. per turn as shown by Albert H. Potter's “tourbillon” published in the book “Ancient Watchmaking”, n ° 22, 2nd semester 1987, pages 64-71.
  • a particularly aesthetic "tourbillon” is known under the name “flying tourbillon”.
  • “flying tourbillon” is described, for example, in the book “Drehgang- uhren” by Alfred Helwig, Verlag der Deutschen Uhrmacher-Zeitung, Berlin 1927. This “flying tourbillon” does not have any element covering the cage.
  • a “whirlwind” known as the flywheel visible on the dial side and exceeding the movement (see the book “Faszination der IJhrentechnik” by Reinhard Meis, page 276, Laterna magica).
  • the object of the present invention is to provide a clever construction of a time indicator of the “balance-wheel” spiral balance type called visible wheel on the dial side. It also aims to provide a solution to the aforementioned disadvantage and to show an economical and flexible method of assembling and / or adjusting watches. Finally, it aims to provide a time indicator for particularly aesthetic and slim wristwatches.
  • the present invention refers to a time indicator of the “swirl” type “balance wheel” known as the flywheel.
  • This so-called steering wheel “tourbillon” is visible on the dial side and includes a balance bridge forming a cage with a ferrule. Its single-tiered cantilever construction supports the whole of the so-called “tourbillon” known as the steering wheel.
  • the single cantilevered bearing is ball bearing.
  • the entire so-called “tourbillon” wheel is designed as an independent tourbillon module, visible from the dial side of the movement and separable from the movement on the other side. All the components can be mounted together and adjusted independently of the movement.
  • the invention Compared to a time indicator with a mechanical regulator of the traditional so-called “tourbillon” balance-spiral type, the invention has the following advantages:
  • the time indicator is provided with a ball bearing cantilevered bearing construction, thus allowing a particularly simple and robust construction, requiring fewer elements.
  • the time indicator is visibly mounted on the side of the dial which has no element covering the cage. This allows a thin construction, easy to obtain and particularly aesthetic. This construction is suitable for large and small calibers.
  • the time indicator includes a tourbillon ferrule, balance bridge, barrel, ball bearing and tourbillon bridge form a tourbillon module supporting the regulating elements, i.e. the pendulum oscillator - spiral with anchor, anchor wheel and pinion and internal gear ring. The whole being completely separable from the movement, having the advantage of being mountable for itself and adjustable outside the movement.
  • This tourbillon module is independent of movement, both for frequency, dressing or adjustment.
  • the balance bridge itself serves as an indicator by its shape and / or its decoration.
  • a balance bridge can be made of a material to allow maximum vision of the moving parts.
  • Such a bridge is for example transparent or semi-transparent, carrying precious stones and / or precious metals and / or ornaments as an indicator.
  • - fig. 1 shows a sectional view of a time indicator with a regulator known as a “tourbillon”,
  • - fig. 2 shows a side view in section of a detail of an exemplary embodiment of a regulator time indicator according to the invention
  • - fig. 3 shows a top view of a detail of an exemplary embodiment of a time indicator with regulator according to FIG. 2.
  • - fig. 4 shows a perspective view of a tourbillon module for a time indicator according to the invention.
  • FIG. 5 shows a rear side view of a movement carrying the tourbillon module according to FIG. 4.
  • FIG. 5 shows the detail D-D of FIG. 5 in section.
  • Fig. 1 shows a sectional view of a so-called “tourbillon” regulator time indicator with spiral balance.
  • a balance, its spiral spring and the swirl ring are assembled inside a rotating cage, the cage rotation speed is 60 sec. per turn.
  • the whole cage revolves around a double bearing gear.
  • Figures 2 and 3 show different views of details of embodiments example of a regulator time indicator according to the invention.
  • Fig. 2 shows a side view in section and fig. 3 shows a top view.
  • This exemplary embodiment of a time indicator of the balance-spiral type refers to a so-called “whirlwind”. It includes a traditional oscillator with balance-spiral-escapement. It works, for example, with Swiss anchor escapement. This exemplary embodiment is in no way limiting. A person skilled in the art, knowing the present invention, can produce a so-called steering wheel “whirlwind” with another exhaust system, for example with a detent exhaust system or with another known regulation system.
  • This oscillator is mounted inside a tourbillon cage.
  • the tourbillon cage rotates around a landing.
  • the “tourbillon” is visible on the dial side 15.
  • the tourbillon cage is formed by a balance bridge 2 being secured to a tourbillon shell 1 by pillars 3.
  • the so-called “tourbillon” flywheel is fully visible and has no element covering the cage.
  • the single bearing is a cantilever construction with ball bearings.
  • the barrel 4 On the bottom side, the barrel 4 is held axially in a ball bearing 5 and by which it rotates freely.
  • This ball bearing 5 is secured by an outer ring to a tourbillon bridge 6.
  • the tourbillon shell 1 is the main diameter part defining the size in the plane of the watch.
  • This tourbillon ferrule receives the teeth collaborating with a last wheel 12 of a movement 13.
  • the oscillator is held by an axis 7 having a first end 9 driven into a barrel 4 integral with the ferrule 1 and a second end 8 driven into the balance bridge 2. These ends may include shock absorbers.
  • the movement of the Swiss anchor type oscillator is maintained by an anchor and an anchor wheel carried by the tourbillon ferrule 1.
  • the anchor and the anchor wheel carried by the tourbillon ferrule 1 rotate with the ferrule vortex 1 around its axis.
  • the anchor wheel carries a pinion 10 which collaborates with an inner gear ring 11 integral with the tourbillon bridge 6, thus creating the rotation of the anchor wheel 10 about its own axis by the movement of the tourbillon ferrule 1.
  • the balance is arranged in a centered manner with respect to the single bearing.
  • This exemplary embodiment is in no way limiting.
  • Those skilled in the art, knowing the present invention can produce a "tourbillon” called a flywheel with a balance arranged eccentrically inside the tourbillon cage.
  • the whirlpool ferrule 1 assembly, balance bridge 2, barrel 4, ball bearing 5 and tourbillon bridge 6 form an integral module supporting the regulating elements, that is to say the balance oscillator- spiral with anchor, anchor wheel and pinion 10 and internal gear ring 11.
  • the whole is a whirlpool module totally separable from movement 13.
  • the tourbillon module has the advantage of being mountable for itself and adjustable outside the movement.
  • This tourbillon module is independent of movement 13, both for frequency, dressing or adjustment.
  • a movement 13 can receive vortex modules of different frequencies and / or of different aesthetic achievements.
  • the assembly and maintenance of such a whirlpool module is particularly easy, quick, economical and flexible.
  • this tourbillon module can be mounted in the watch at the last moment.
  • the so-called “tourbillon” wheel according to the invention is arranged in the plane of the dial 15 of a watch or wristwatch in a visible manner on the dial side in a six o'clock or twelve o'clock position. Due to its small thickness, this so-called “tourbillon” flywheel can be arranged in the movement 13 in a raised manner relative to the dial 15, making the “tourbillon” and its elements particularly clearly visible.
  • An indicator hand can be fixed on the balance bridge 2, for example an indicator hand 14 of small seconds.
  • the balance bridge 2 can itself serve as an indicator by its shape and / or by an associated decoration.
  • the balance bridge 2 is for example made transparent or semi-transparent. He can wear precious stones and / or precious metals and / or ornaments as an indicator. Those skilled in the art, knowing the present invention can perform other embodiments of such indicators.
  • This “tourbillon” is visible on the dial side 15.
  • the total height of the tourbillon module can vary to cause the surface of the tourbillon to exceed the dial 15 while remaining below the passage of the minute and hour hands 16,17.
  • Compatibility between a family of movements and a family of tourbillon modules is done using an interface, thus ensuring the interchangeability of tourbillon modules.
  • the interface element ensures that the tourbillon ring 1 maintains a characteristic rotation speed of, for example, 60 sec. per turn. This is achieved by an interface element for example by the geometry of its teeth, by the number of teeth, by the shape and by the positioning of the teeth in the movement 13, so as to collaborate perfectly with the last wheel 12 of movement 13.
  • the gear ratio must be adjusted so as to ensure the condition of interchangeability. If, for example, the frequency of the oscillator is reduced by a factor, then the pitch diameter ratio between the pinion 10 and the internal gear ring 11 must increase by the same factor.
  • FIGS 4, 5 and 6 serve to illustrate in more detail the modularity of the tourbillon of the time indicator according to the invention.
  • Fig. 4 schematically shows a perspective view of an exemplary embodiment of a flying tourbillon module 20 for a time indicator according to the invention.
  • the tourbillon is in principle the same as the tourbillon already shown in Figures 2 and 3. It contains a balance 21 mounted on an axis 7 with a first end 9 and a second end 8, a spiral 22, a tourbillon ferrule 1, pillars 3, a balance bridge 2, a barrel 4, an inner gear crown 11, a ball bearing 5, and a pinion 10.
  • the tourbillon is mounted on a tourbillon bridge 6.
  • the balance 21, its spiral spring 22 and the tourbillon shell 1 are assembled inside a rotating cage formed by the pillars 3, the balance bridge 2 and tourbillon shell 1.
  • Fig. 5 shows a view from the bottom or rear side (opposite side of the dial side) of a movement 13 with a tourbillon module 20 as illustrated in FIG. 4, which is mounted on movement 13.
  • the tourbillon module or rather the tourbillon bridge 6 is fixed on this bottom side of the movement 13 using the screws 24, so that to separate the tourbillon module 20 from the movement 13, it is only necessary to unscrew the screws 24 and pull the module 20 from the movement 13.
  • the swirl ferrule 1 receives the toothing collaborating with a last wheel (not shown) arranged in a recess 12 of the movement 13.
  • Fig. 6 shows in section the detail D-D of FIG. 5.
  • the present figure resembles fig. 2 but more clearly shows the modularity of the tourbillon and its extension in the movement 13.
  • the tourbillon bridge 6 is fixed on the back or rear side of the movement 13 and the tourbillon module 20 extends in an opening 18 of the movement 13 up to to the dial side 15 thereof.
  • the ball bearing 5 is not arranged on the same level as the first end 9 of the axis 7 (as illustrated in FIG. 2) but it is spaced from this first end 9 of this axis 7 towards the level of the center of gravity of the rotary module.
  • This position of the landing as close as possible to the center of gravity makes the arrangement more insensitive against shock.
  • Fig. 6 clearly shows that to disassemble the tourbillon module 20 from the movement 13 it is not necessary to disassemble any other part.
  • this tourbillon module can be mounted in the watch at the last moment. It means that movement 13 and the tourbillon module can be manufactured and assembled completely separately.
