    Description
    TECHNICAL FIELD OF THE INVENTION
    The invention relates to the field of watchmaking. The invention particularly relates to a watch movement comprising a plate, a first vortex and a second vortex.
    STATE OF THE ART
    [0002] In watchmaking, a vortex, also called a "rotating cage", is a horological complication, added to the escapement mechanism and intended to improve the accuracy of mechanical watches by counterbalancing the disturbances of balance isochronism due to gravity. earthly. This mechanism was invented by the French watchmaker Abraham-Louis Breguet in 1801. Subsequently, some watchmakers, eager to further improve the precision of their movements, produced watch movements equipped with two vortices. However, in return for greater accuracy, these movements are bulky, which prohibits their use for some watch cases of reduced size.
    SUMMARY OF THE INVENTION
    The invention aims to remedy this defect by providing a clockwork movement with two swirls whose size is limited.
    This object is achieved by a watch movement according to the invention, said movement comprising at least one plate, a first vortex, having a first axis of rotation, and a second vortex, having a second axis of rotation, and connecting elements fixing the first vortex and the second vortex to the plate so that the first axis of rotation and the second axis of rotation coincide.
    According to a feature of the invention, the first axis of rotation and the second axis of rotation may both be perpendicular to the longitudinal plane of the plate.
    Alternatively, the first axis of rotation and the second axis of rotation may both be parallel to the longitudinal plane of the plate.
    Alternatively, the first axis of rotation and the second axis of rotation can both be oblique with respect to the longitudinal plane of the plate.
    According to another characteristic, the connecting elements may comprise a first ball bearing and a second ball bearing.
    According to another characteristic, the assembly elements may comprise a first support and a second support.
    According to another characteristic, the assembly elements may comprise a first hub at least partially groove and a second hub at least partially groove.
    According to another characteristic, the connecting elements may comprise a first guide stone and a second guide stone.
    According to another characteristic, the connecting elements may comprise a first bridge and a second bridge between which are arranged the first vortex and the second vortex.
    According to another aspect of the invention, a timepiece comprises a movement as described above.
    BRIEF DESCRIPTION OF THE FIGURES
    The invention will be better understood by those skilled in the art on reading the detailed description which follows, in connection with the figures which illustrate: FIG. 1, an exploded view of the watch movement according to a first embodiment of the invention; fig. 2, a perspective view of a tourbillon assembled according to a first embodiment of the invention; fig. 3, a perspective view of a movement according to a first embodiment of the invention; and FIG. 4, an exploded view of a movement according to a second embodiment of the invention.
    DETAILED DESCRIPTION OF THE INVENTION
    According to the first embodiment of the invention, shown in FIGS. 1-3, the movement comprises a first vortex 1 and a second vortex 2 arranged coaxially within the movement by means of connecting elements comprising, inter alia, several ball bearings. In other words, the vortices are arranged within the movement so that the axis of rotation 15 of the first vortex 1 and the axis of rotation 15 of the second vortex

    Claims (10)
    [1]
    Whirlpool 2 are confused. In addition, as shown in FIG. 1, the axis of rotation of the first vortex and the axis of rotation of the second vortex are both perpendicular to the longitudinal plane of the plate 3, that is to say the plane defined by one of the faces 4 of the Platinum 3. As shown in FIG. 1, the ball bearing 9 of the first vortex 1 is driven into the support 5 of the first vortex 1 and the fixed second wheel 7 of the first vortex 1 is driven around the support 5 of the first vortex 1. [0017] The ball bearing 10 of the second vortex 2 is driven into the support 6 of the second vortex 2 and the fixed second wheel 8 of the second vortex 2 is driven around the support of the second vortex 6. The supports 5 and 6 of the first and second vortices are screwed to the plate 3 by means of the screws 13 and 14. Ideally, the plate 3 is provided with four protuberances 17 having a profile complementary to that of holes drilled transversely in the supports 5 and 6. As shown in FIG. 2, each of the vortices is traversed in its axis of rotation by a hub 16 at least partially grooved. Each hub is secured to the bearing by means of the circlips 11 and 12, thus fixing each vortex to its respective support and therefore to the plate 3. Alternatively, the hubs are held by nuts or any other equivalent attachment means. In FIG. 3, the two assemblies previously described are represented in their operating configuration. According to the second embodiment of the invention, shown in FIG. 4, the movement comprises a first vortex 101 and a second vortex 102 arranged coaxially within the movement by means of connecting elements including, inter alia, guide stones. As in the previous embodiment, the axis of rotation of the first vortex 101 and the axis of rotation of the second vortex 102 are merged. In addition, the axis of rotation of the first vortex 101 and the axis of rotation of the second vortex 102 are both perpendicular to the longitudinal plane of the plate 103, that is to say the plane defined by one of the faces 104 of the plate 103. The lower guide stones 105 and 106 of the first and second vortices and the fixed seconds wheels 107 and 108 of the first and second vortices are driven coaxially in the plate 103. For this, the plate 103 is machined to present a fixing lug 115 shaped so as to receive these elements. The upper guide stone 111 of the first vortex 101 is driven into the bridge 109 of the first vortex. The upper guide stone 112 of the second vortex 102 is driven into the bridge 110 of the second vortex. The first vortex 101 is inserted in the lower guide stone 105 of the first vortex 101. The first vortex bridge 109 is fixed to the plate, positioning and thus maintaining the first vortex through the guide stone upper 111 of the first vortex 101. The bridge of the first vortex 109 is screwed onto the plate 103 by means of the screws 113. [0025] The second vortex 102 is inserted into the lower guide stone 106 of the second vortex 102. second vortex 110 is attached to the platen, positioning and thereby maintaining the second vortex 102 through the upper guidewire 112 of the second vortex. The bridge 110 of the second vortex 102 is screwed onto the plate 103 by means of the screws 114. [0026] The two embodiments of the invention described above have mechanisms for arranging within a two clockwork movement coaxial vortices with their common axis of rotation perpendicular to the longitudinal plane of the plate. However, it is obvious that some minor modifications, in particular minor modifications relating to the shape of the plate, make it possible to adapt these mechanisms in order to arrange two vortices with a common axis of rotation parallel to the plane longitudinal of the plate or oblique vis-à-vis this plane. The invention also relates to a timepiece comprising a movement as described above, preferably any wristwatch whose housing contains such a movement. claims
