An input mobile i.e. reverser mobile (30), of the gear train is kinematically coupled to the oscillating weight through a return mobile (20). The oscillating weight is arranged such that a support (18) of the oscillating weight pivots in a plane located between a movement plate and the set of indicators. The return mobile is arranged between one of the indicators closest to the plate and the input mobile.

Description

Technical area

The present invention relates to a self-winding watch movement and more particularly, a movement comprising an oscillating mass producing the energy necessary for the movement, mounted on the side of the plate and simple construction.

State of the art

[0002] In most known self-winding watch movements, an oscillating rotating mass is mounted under the movement, on the bridge side thereof, between the bottom of the box and the movement. These movements also include a gear train for transmitting the energy produced by the oscillating mass to a barrel. Such devices are well known to those skilled in the art and reference may be made to Reymondin's "Theory of Watchmaking". al., Federation of Technical Schools, 1998, pages 169 to 188 for more details on these.

[0003] Self-winding movements are known in which the oscillating rotating mass is placed on the platinum side of the movement. Such a movement is described for example in patent CH685363. This arrangement of the oscillating mass makes it possible to fulfill a decorative function, in addition to its function of producing energy. Indeed, such a device makes it possible to see directly through the watch glass the oscillating mass may have decorative patterns on its surface, in addition to an "active" function due to its oscillation.

These movements require, however, to modify the gear train to ensure the transmission of energy produced by the oscillating weight mounted platinum side cylinder. For example, in patent CH685363, the ratchet is mounted on the platinum side end of the barrel shaft and not at its opposite end as is usually the case. In addition, the cogs of the gear train are moved platinum side. A movement comprising two oscillating masses arranged on one side bridges and the other side platinum, is described in the patent CH686542. The two oscillating masses are interconnected by a connecting module disposed at the periphery of the movement. This device is that complex and bulky pendant.

Brief summary of the invention

An object of the present invention is to provide a self-winding watch movement free from the limitations of the prior art known.

According to the invention, these objects are achieved in particular by means of a self-winding watch movement comprising: a set of indicators for displaying the current time; an oscillating mass comprising a support; a barrel; a gear train comprising an input moving wheel and ensuring the transmission between the barrel and the oscillating mass, the input gear of the gear train being coupled kinematically to the oscillating weight via a first gear wheel; return; characterized in that the oscillating mass is arranged so that the support pivots in a plane between a platen of the movement and the indicator set; and in that the first moving wheel is arranged between the indicator closest to the plate and the input mobile.

In one embodiment, said deflecting wheel may be formed of a first return wheel coupled kinematically with a sprocket of the oscillating mass, and a first sprocket gear engaged with the input mobile.

In another embodiment, the input mobile can be a mobile inverter comprising an inverter wheel engaged with the first mobile deflection.

[0009] In yet another embodiment, the movement may further comprise a second return mobile, the input gear of the gear train being kinematically coupled to the oscillating weight via the first and second movable gear. reference.

The invention also relates to a watch comprising the movement according to the embodiments.

This solution has the advantage over the prior art to provide a self-winding watch movement comprising oscillating rotating mass mounted platinum side while being of simple construction and requiring a minimum of modification compared to a movement conventional.

Brief description of the figures

Examples of implementation of the invention are indicated in the description illustrated by the appended figures in which: <tb> Fig. 1 <sep> illustrates a sectional view of an automatic watch movement with a conventional winding mechanism; <tb> fig. 2 <sep> shows the movement according to a first embodiment; and <tb> fig. 3 <sep> shows the movement according to a third embodiment.

Example (s) of embodiment of the invention

FIG. 1 shows a sectional view of an automatic watch movement 1 according to a plane passing through the axis thereof, and more particularly, a conventional winding mechanism for the automatic watch movement.

Note in FIG. 1que this winding mechanism comprises an oscillating mass 10, pivotally mounted in the center of the movement 1 and disposed on the side of the bridges of the movement 1, according to a conventional arrangement of conventional automatic watches. More particularly, the oscillating mass 10 is typically composed of a support 18 and a heavy sector 11 disposed at its periphery. Preferably, the support 18 takes the form of a board that can be perforated. Advantageously, the pivoting of the oscillating mass 10 is carried out by means of a roller bearing 12. More specifically, the bearing 12 comprises an inner ring 15 fixed on a first gear bridge 110, and an outer race 16, balls 17 being interposed between the two rings. The outer ring 16 is integral with the support 18 of the oscillating mass 10, and comprises a pinion 14 which is also integral therewith.

The winding mechanism also comprises a barrel 60 comprising a barrel shaft 62 on which is fixed a ratchet wheel 61 for the winding of the barrel 60. The barrel 60 pivotally mounted via the shaft 62 on a platen 100 of the movement 1 and a barrel bridge 64.

The ratchet wheel 61 is actuated by a gear train of the winding mechanism, also disposed on the side of the bridges of the movement 1. The gear train comprises a mobile input, here a mobile inverter 30, a first and second reduction mobile 40, 41, and an output mobile, here a third reduction mobile 42, driving the ratchet wheel 61. The inverting mobile 30, comprising an inverter wheel 31 and an inverter pinion 32 , is pivotally mounted between the plate 100 and the first gear bridge 110. The reduction gear 40, 41, 42 are pivotally mounted between the barrel bridge 64 and a second gear bridge 120. The third reduction gear 42 causes the Ratchet wheel 61. More particularly, the first reduction wheel 40 comprises a first reduction wheel 43 that engages with an inverter gear 32, and a first reduction gear 44 in engagement with a second reduction gear 45. The second reduction wheel 42 comprises a third reduction wheel 46 meshing with the second reduction wheel 45, and a third reduction gear 47 meshing with the ratchet wheel 61.

The oscillating mass 10 is coupled kinematically with the gear train via a first deflection wheel 20. In the example of FIG. 1, the first deflection wheel 20 is formed of a first deflection wheel 21 engaged with a toothing of the pinion 14 of the oscillating mass 10, and a first idler gear 22 in engagement with the inverter wheel 31 The first mobile 20 is pivotally mounted on the plate 100, for example by means of a pin 23. When the mobile 20 turns in one direction or the other, under the action of the mass oscillating, it drives the mobile inverter 30 in a direction of rotation which is always the same. The ratchet wheel 61 is therefore driven in a single direction of rotation by means of the winding train. In this conventional configuration of self-winding watch movement, the deflection wheel 20 is arranged between the inverting mobile 30 and the toothing of the pinion 14. As the oscillating mass 10 is mounted on the side of the bridges of the movement 1, the diverting wheel 20 is thus arranged between the mobile inverter 30 and the side of the bridges of the movement 1.

FIG. 1 also shows a set of indicators for the display of the current time comprising indicators of the minutes 80 and 83 hours, here needles, mounted respectively on a gun minutes 81 and hours 83. A seconds indicator 84, also a needle, is attached to a mobile seconds 85. The indicators 80, 83, 84 are driven by the rotation of the barrel 60, through a conventional timer train not shown, for example, a multiplicative gear with medium wheel.

Figs. 2 and 3 illustrate a sectional view of the automatic watch movement 1 according to a first and second embodiment of the invention. In these two figures, the plate, the barrel bridge, and the first and second gears are not shown for the sake of clarity.

In these two embodiments, the oscillating mass 10 is pivotally mounted on the platen side, in the center of the movement 1. In the example of FIGS. 2 and 3, inner ring 15 of the rolling ball bearing 12 is mounted around the hour barrel 83 so that the support 18 pivots between the indicators 80, 82, 84 and the plate 100, and a dial (not shown) which can to be fixed on the plate 100, between the plate 100 and the indicators 80, 82, 84. The inner ring 15 may for example be driven on the hour barrel 83 so as to form a pivot bearing. The arrangement of the barrel 60, the ratchet wheel 61 and the winding train is identical to that described in the example of FIG. 1. The arrangement of the gear train, comprising the reversing mobile 30, the first, second and third reduction gear 40, 41, 42, is also identical to that of FIG. 1.

The oscillating mass 10 is kinematically coupled to the gear train via the first deflection wheel 20, so that the first deflection wheel 21 is engaged with a toothing of the pinion 14 of the oscillating mass 10, and that the first idler gear 22 is engaged with the inverter wheel 31. According to the invention, this coupling is achieved by arranging the first deflection wheel 20 between the indicator closest to the plate, ie the hour indicator in the example of Figure 2, and the mobile inverter 30. In this configuration, the first return wheel 21 is between the indicator closest to the platen and the platen, and at least a portion of the first gear 22 passes through the plate. The first mobile 20 can be pivotally mounted on the plate, for example by means of the pin (not shown in Figure 2). In an embodiment not shown, the first mobile 20 is pivotally mounted on an axis fixed between the plate and the first gear bridge.

In the embodiment shown in FIG. 3, the oscillating mass 10 is kinematically coupled to the gear train via the first deflection wheel 20 and a second deflection wheel 24. In the example of FIG. 3, the first deflection wheel 20 is composed only of a first idler gear 22 engaging the reversing gear 30 of the gear train. The second deflection wheel 24 comprises a second deflection wheel 25, in engagement with the toothing of the pinion 14 of the oscillating mass 10, and a second idler gear 26, in engagement with the first idler gear 22. 24 is pivotally mounted on the plate with a pin (not shown), the side of the indicators 80, 82, 84. More particularly in the example of FIG. 3, the second deflection wheel 24 is pivotally mounted between the plate and the first gear bridge via an axis 27. Other ways of mounting the first deflection wheel 20 and the second deflection wheel 24 are however also possible.

Other configurations for coupling the oscillating mass 10 to the gear train are also possible. For example, in an embodiment that is not shown, the second deflection wheel 24 is formed of the only second deflection wheel 25 that engages with the toothing of the pinion 14 of the oscillating mass 10. The first deflection wheel 20 is mounted with such that the first deflection wheel 21 engages the reversing moving wheel 30 while the first deflection gear 22 engages with the second deflection wheel 24. In this configuration, the second deflection wheel 24 can be pivotally mounted on the plate 100, on the side of the indicators 80, 82, 84, while the mobile 20 can be mounted as described in the example of FIG. 1.

The solution of the invention has the particular advantage of providing a self-winding watch movement comprising the oscillating rotating mass 10 mounted platinum side 100, without the need to modify the gear train and the barrel a conventional winding mechanism where the oscillating weight is mounted on the side of the bridges. This is accomplished by changing the arrangement of the first diverting wheel 20 according to the embodiments. The modification to be made to the conventional self-winding movement is therefore minimal and the modified movement remains simple.
