Definitions

  • the present invention relates to a vortex mechanism for improve the operating precision of the regulating organ and more specifically to improve the mechanical construction of such a mechanism leading to more high positioning accuracy of the parts forming these mechanisms.
  • Whirlpool mechanisms have been known since the first device of this genre imagined by A.-L. Breguet in 1801 in a variety of embodiments.
  • Such a mechanism includes a cage pivotally mounted in the case of the timepiece concerned, this cage carrying all the exhaust organs and the regulating organ. Due to complexity and purpose aforementioned of such a mechanism, all the elements of a vortex mechanism Among other things, they should be positioned as precisely as possible.
  • the anchor and the escape wheel are subject to possible improvements concerning among other things their positioning, one by relative to the other using the cage, or even on an element fixed to the latter, this in order to increase the precision of this positioning and of the guidance of the elements during the operation of the mechanism.
  • the object of the present invention is to remedy the aforementioned drawbacks and allow the realization of a simple tourbillon mechanism with a number of parts and a reduced weight ensuring at the same time the concentricity of elements and stiffness of the cage as well as guaranteeing easy positioning and precise anchor and escape wheel on the cage ensuring simultaneously better guidance of these.
  • the object of the present invention is therefore a vortex mechanism which is distinguished by the characteristics set out in claims 1 and 6 and / or dependent claims.
  • the drawing illustrates schematically and by way of example a shape of execution of a tourbillon mechanism according to the present invention.
  • Figure 1 shows the cage of the vortex mechanism and the elements mounted on the cage, specifically a monolithic bridge for mounting the anchor and the escape wheel.
  • Figures 2a and 2b show sections of the cage along line A-A of Figure 1, once in plan and once in perspective.
  • Figure 3 is a perspective view of the monolithic bridge for positioning of the escape wheel and the anchor.
  • a tourbillon mechanism comprises, as shown schematically in Figure 1, a cage 1 which is mounted in a pivoting around a pinion 2 in the case of the timepiece to which it is intended for.
  • this cage includes a upper part 1a and lower part 1b intended to be superposed one on the other in order to form the cage 1.
  • the solution envisaged by the present invention ensures the equidistance of the two planes upper parts 1a and lower 1b as well as their concentricity and coaxiality all along their periphery. While reducing the number of parts forming the cage 1 of the mechanism and, consequently, facilitating the assembly of cage 1, its rigidity is higher compared to the conventional solution known at the time.
  • the assembly of the cage is done by means of the cylindrical skirts of the upper 1a and lower 1b parts, that is to say walls substantially forming a cylinder body, these skirts cylindrical being adapted to be combined in order to form the entire cage.
  • Positioning elements 1c of different shapes can ensure the desired orientation and positioning of the upper 1a and lower 1b parts one over the other.
  • these positioning elements 1c are produced by fitting the cylindrical skirts of the upper 1a and lower 1b to their end oriented in the center of the cage 1 with a radial narrowing, one at inside and the other outside as in Figures 2a and 2b, so that the two parts 1a and 1b fit together and are positioned precisely one by relative to each other and relative to the pendulum axis.
  • These two parts 1a and 1b are therefore guided with regard to their positioning by their cylindrical skirts and more specifically by their positioning elements 1c or training interlocking, that is to say by elements concentric with the axis of the cage 1, so that the axis of cage 1 is perfectly aligned on the same axis as the pendulum, thus defining an optimal concentricity.
  • the fixing of these parts can be done by means of different solutions, for example using 1d screws placed in holes provided for this effect in the cylindrical skirts of the upper 1a and lower 1b parts; the skirts may be locally thicker in places provided with these orifices intended to receive the 1d screws, these skirts preferably joining the bridges of the cage also come from a manufacturing part with said skirts carrying the other elements which are not important in the context of the present invention and will therefore not be described in detail here.
  • the two parts 1a, 1b of the cage are made of an alloy aluminum treated by anodic oxidation. Besides the rigidity of this material and the resulting benefits mentioned above, this also makes the cage lighter than a cage conventionally matched with the three pillars usual.
  • the present invention guarantees several advantages, even a number reduced parts and easy assembly of the cage 1, a reduced weight, a high rigidity and above all improved precision in the concentricity of the parts forming the cage 1 and elements mounted thereon relative to the pendulum axis.
  • a tourbillon mechanism comprises a cage 1 associated with a monolithic bridge 7, that is to say in one piece, which ensures the positioning of an escape wheel 3 and simultaneously of a anchor 5 and which is illustrated diagrammatically in FIG. 3.
  • the monolithic bridge 7 preferably has substantially the shape of a circular segment which bypasses the elements in the center of the cage and which is fitted with holes and housing. This monolithic bridge 7 is concentric with the axis of the cage 1 of the whirlwind.
  • the escape wheel 3 is pivotally mounted around a pinion of the escape wheel 4, the anchor 5 is mounted around an anchor rod 6.
  • These two supplies 4 and 6 are both mounted, in the case shown in Figure 1 at their upper end, on the monolithic bridge 7 in two bearings 7b and 7c receiving the pivots of the anchor and the wheel exhaust so that the anchor 5 can work with the wheel exhaust for normal operation of a vortex mechanism which does not will not be described in more detail below, since this operation is not essential for the invention.
  • this monolithic bridge 7 may include a pinion bearing 7b designed to accommodate the pinion of the pinion which is intended to mesh with yet other cogs.
  • the fact mounting the anchor 5 and the escape wheel 3 on a monolithic bridge improves the precision of their reciprocal positioning and their guidance. In addition, such system makes the tourbillon mechanism and its cage 1 fitted with this bridge monolithic 7 more compact.
  • the attachment of the monolithic bridge 7 to the cage 1 is also done by preferably using screws housed in holes 7a provided for this purpose in both ends of the monolithic bridge 7 and corresponding threads practiced in guide tubes themselves driven into the upper arms of cage 1.
  • the entire cage 1 associated with the monolithic bridge 7 ensures improved accuracy over the state of the art with respect to the concentricity of the axis of the cage 1 and the pendulum as well as the positioning of the escape wheel 3 and the anchor 5 and thus contributes to improving the precision of functioning of the regulatory body.
  • the monolithic bridge 7 could be used with a conventional swirl cage with screwed pillars for fixing upper and lower cages.
  • the cage 1 with interlocking cylindrical skirts can be used with two bridges, one for the pivoting of the anchor and the other for that of the wheel exhaust.
