    Technical area
    The present invention relates to the field of watchmaking. It relates, more particularly, to a timepiece comprising:a box,a movement housed in the box,an ice cream closing the box,a dial arranged between the movement and the ice.
    This dial comprises two polarized lenses, at least one of which is mounted on a movable frame, so that said polarized lenses can occupy a first state in which elements located behind the dial in reference to the ice are visible from the side of the ice and a second state in which said elements are hidden.
    State of the art
    The Applicant is already the holder of EP 2 185 979, in which is described a timepiece as defined in the preamble above. The embodiment mainly described proposes to implement a lid associated with the box. When the lid is closed, the two polarized lenses forming the dial do not let the light and only visible on a black background constituted by the dial, needles to indicate, for example the current time. When the lid is open, the two polarized glasses allow at least a portion of the light to pass so that the particular indications displayed behind the dial or any openings revealing the movement are visible through the dial.
    In the aforementioned document, the cover is kinematically connected to the polarized lenses, by means of a differential providing adequate gearing and to control the positions occupied by the polarized lenses, respectively when the lid is open or closed.
    It is also proposed in this document to act on the polarized lenses, via a rotating bezel, without however describe precisely how the rotating bezel is connected to the differential input. It is also proposed to connect the lid and the polarized lenses, by a train of references, for example to operate a polarized lens of small size, arranged on a sub-dial.
    The implementation of a differential in the device described in EP 2 185 979, has the advantage of allowing to obtain a significant reduction ratio in a reduced space. However, its implementation is complex and the watch case incorporating this differential is, in itself, a true horological complication.
    In order to obtain a simpler box construction, one can effectively remove the differential and remove the lid, by operating the polarized lenses by a rotating bezel. However, the implementation of such a solution is not self-evident. Indeed, the immediate solution that one might think, would be a direct attachment of the rotating bezel and one of the polarized lenses, but this is not without problems sealing. Moreover, if one wants to create a kinematic connection between such a rotating bezel and at least one of the polarized lenses when these glasses have dimensions that cover the entire dial, we find ourselves facing particularly delicate spatial constraints if we want to make the kinematic link invisible.
    The present invention aims to solve the aforementioned problems, by providing an implementation of a timepiece with a dial in the form of two polarized lenses, simpler, without prejudice to reliability and reliability. the quality of the construction, especially the watch case.
    Disclosure of the invention
    More specifically, the invention relates to a timepiece comprising:a box comprising a bottom, a middle part and a control member movably mounted with reference to the middle part,a movement housed in the box,an ice cream closing the box,a dial disposed between the movement and the mirror, said dial comprising two polarized lenses, at least one of which is movably mounted, so that the polarized lenses can occupy a first state in which elements located behind the dial in reference ice are visible and a second state in which said elements are hidden.
    According to the invention, the mobile polarized lens is flexible, is kinematically connected to the control member (16) and is arranged to be moved linearly.
    Brief description of the drawings
    Other details of the invention will appear more clearly on reading the description which follows, with reference to the accompanying figures. Fig. 1 shows in cross section a timepiece to illustrate the invention. Fig. 2 illustrates a detail of the construction of the timepiece of FIG. 1.
    Embodiment of the invention
    The timepiece illustrated in FIGS. 1 and 2 is in accordance with the teachings of EP 2 185 979 and comprises a box 10 comprising a bottom 12, a middle part 14 and a rotating bezel 16 movably mounted with reference to the middle part 14. The bottom 12 may be at least partially transparent. Aspects of box construction that are not part of the present invention will not be described in detail.
    A movement 18 is mounted in the box, typically via a casing ring 20. In the example, the movement is chronograph type. It makes it possible to display a current time by main display members 22. It also makes it possible to display a time timed by secondary display members 24. The timepiece comprises, in the example, three sub-components. eccentric dials each associated with a small hand, to display information relating to the timed time, possibly a small second or other information relating to the current time. The concept of "small needle" is known to those skilled in the art without the term "small" does not pose a problem of clarity.
    [0014] Conventionally, an ice 26 closes the box. A dial 28 is disposed between the movement 18 and the mirror 26. The dial 28 comprises two polarized lenses 28a and 28b, at least one of which is mounted, according to the proposed example, on a mobile frame 30, so as to that the polarized lenses 28a, 28b can occupy a first state in which elements located behind the dial 28 with reference to the mirror 26 are visible from the dial side and a second state in which said elements are hidden. The movable frame 30 is pivotally mounted about an axis located at the center of the movement 18. According to the example, only one of the polarized lenses is mobile, the other is fixed.
    In the example shown, the display members are disposed between the dial 28 and the window 26, so that they are always visible by a user, either on the bottom 12 of the movement 18 when the polarized lenses 28a, 28b are in the first state, either on bottom 12 of the dial 28 when the polarized lenses 28a, 28b are in their second state. The display members which are pivoted in the center of the movement 18, are assembled on tubes which pass through the dial 28 at the center of rotation of the movable frame 30, so that a simple passage of substantially circular shape formed through the dial 28 , makes it possible to carry out the displacements of the mobile frame 30 and the polarized glass which it carries.
    Regarding the display members which are rotated in eccentric sub-dials, they are assembled on tubes that pass through the sub-dials at their center. If a simple opening of substantially circular shape, formed in the fixed polarized glass in the center of the sub-dial, is sufficient, however, it is necessary to provide an opening in the form of an arc of a circle, centered on the center of rotation of the mobile frame 30, in the polarized glass carried by the movable frame 30, to allow the passage of the tubes during the movements of the movable frame 30.
    For moving the movable frame 30 and therefore one 28a polarized glasses, there is provided a kinematic connection between the rotating bezel 16 and the movable frame 30. Advantageously, this kinematic connection comprises a first 32 fixed teeth of the telescope. The first toothing 32 can be machined in the bezel or attached to it. The teeth can be oriented towards the inside or the outside of the timepiece. The movable frame 30 is also provided with a second toothing 34.
    The kinematic connection also comprises a gear mounted pivotally mounted on the middle 14, for kinematically connected the first toothing 32 and the second toothing 34. As can be seen in the drawings, the middle part 14 is shaped so as to have a seat 36 formed parallel to the plane defined by the movement 18. This seat 36 is extended by a flange 38, on which is fixed in particular the glass 26. Furthermore, the bezel is pivotally mounted on the middle part 14, being guided by the seat 36 and the flange 38, and extends to cover the flange 38. Finally, a stretcher 40 is disposed at the periphery of the box, at the interface between the middle part 14 and the bezel.
    A housing 42 is formed in the bezel at the interface with the seat 36 and facing it. The gear train is advantageously mounted on the seat 36, in the housing 42.
    More particularly, the gear train comprises a first mobile 44 meshing with the first toothing 32. This first mobile 44 is mounted on a shaft 46 which passes through the seat 36 orthogonally and which is pivoted on it. A sealing system, such as a seal, is interposed between the shaft 46 and the middle part 14. The gear train also comprises a second mobile 50 assembled on the shaft 46, on the other side of the seat 36. The assembly can be done, according to the proposed example, by a flat screw 52, which makes it possible to clamp the second mobile 50 between the screw head and a flange that has the shaft 46.
    The gear train further comprises a third mobile 54, located in the same plane as the second mobile 50, the plane being parallel to the plane defined by the movement 18. The third mobile 54 is engaged with the second mobile 50 with the second toothing 34. The third mobile 54 is also pivoted on the middle part 14. It can be connected to a second shaft 48 which, parallel to the first, passes through the seat 36 of the caseband 14.
    Thus, the fact of having a gear train mounted on the middle part 14 and comprising at least two mobiles (50 and 54) located in the same plane parallel to the plane of the movement 18 and at least two movable (44 and 50) interconnected by a shaft 46 pivoted on the middle part 14 and orthogonal to it, makes it possible to adapt the diameter of the mobiles to the spatial constraints of the box 10, in particular by arranging a mobile of small diameter at the level of the first toothing 32 , where the space available between the bezel and the middle part 14, is very limited. It is also possible to introduce a gear ratio between the second 50 and the third 54 mobiles, to improve the ergonomics of the operation of polarized lenses 28a, 28b, that is to say by adjusting the angle of rotation of the telescope required for the passage of polarized lenses 28a, 28b from one state to another.
    The implementation of such a kinematic connection can also make it possible to easily adjust the number of mobiles located in the same plane, to achieve meshing with the second toothing 34, in any position, depending on the constraints. specific to a particular construction to specifically operate a mobile frame associated with a particular sub-dial or a particular dial area.
    It is also possible to drive, from a suitable kinematic connection, several mobile frames, each carrying a polarized lens. Preferably, each of the mobile frames is associated with a particular area of the dial, for example at one or other of the sub-dials. On this basis, it is possible to operate the different mobile frames in a coordinated and synchronized manner, simultaneously or sequentially.
    From the embodiment that has just been described, one could also provide to have each of the two polarized lenses 28a, 28b on a movable frame 30 and to drive them both by the rotating bezel, by means of first and second kinematic links as mentioned above. It is thus possible, for example, by rotating each of the frames in two opposite directions, to have a change of state by means of a limited rotation of the telescope. One could have the first mobile common to both kinematic chains and mount two mobiles at different levels on the shaft, one being part of the first kinematic link and the other part of the second kinematic link.
    With this kinematic connection, it is even possible to couple the actuation of the polarized lenses 28a, 28b to another function also carried out via the telescope, in interaction with the movement 18, in particular a control function of FIG. a display.
    Between the rotating bezel 16 and the middle part 14, more particularly the seat 36, it is also possible to provide a notch, typically by means of one or more ball pawls 56, secured to the rotating bezel 16 or the seat 36. The ball or pawls can cooperate with a recess 58 formed in the seat 36 or in the rotating bezel 16, respectively. Advantageously, engagement of the notching when the polarized lenses 28a, 28b are respectively in their first and in their second states and only in these states, in order to clearly indicate to the user that the rotating bezel 16 is in the position corresponding to these states. According to the example, there is commitment of notching when the ball snaps into the recess. In the case of variants with several mobile frames actuated sequentially, the successive actuating positions of the various frames can be signified by several notched positions.
    To prevent the moving frame 30 from being driven beyond a first and a second extreme position, respectively corresponding to the first and second state polarized lenses 28a, 28b, these extreme positions can be defined by stops made between the movable frame 30 and a reference element, for example the middle 14. In order not to damage the device if it is forced on the abutment, the skilled person may introduce a clutch, friction / lantern in the gear train, typically at one of the mobile mounted on the first shaft 46. Alternatively, the clutch can be achieved by having teeth of limited length, so that it is not possible to cause the frame to beyond these extreme positions. There will be provided a spring system, ideally arranged on the stops, to avoid latency or blocking, when actuated in the reverse direction of the movable frame 30. More specifically, one can have a stop that can be moved slightly in case of support, the movement of the stop causing a stressing of a spring to push the stop. It is also possible to have an elastic zone on the abutment, either by producing a resilient and resilient abutment or by interposing a spring member between the abutment and the element (movable frame 30 or bezel) which abuts on it.
    The present invention is a variant of the particular example above, in which it is expected to replace the rotating bezel 16 by another control member kinematically connected to one of the polarized lenses. Optionally, a movable frame can be used to kinematically connect the control member with the movable lens.
    Advantageously, it is thus possible to provide that the control member is designed as a slide mounted movably with reference to the box, this slide being associated with a rack which meshes with the first mobile of a train of referrals . The slide can be mounted mobile in translation or rotation typically at the periphery of the box, according to the shape of the latter, respectively substantially rectangular or round.
    In the case of a displacement in translation of the slide, it can then connect this slide kinematically to a flexible polarized lens arranged to be moved between a second position in which it forms the second state of the dial superimposed with the other polarized glass and a first position in which it forms the first state of the dial and does not appear in superposition with the other polarized glass. It can then be wrapped in a slot of the box or retracted on the other side of the movement. The control member then advantageously drives a roller around which can take place the flexible polarized glass. We thus obtain a curtain effect that moves in translation to "open" or "close" on the dial. As has been described above, the movable glass has slots of ad-hoc shape, to allow the passage of the display members.
    The drive of a flexible polarized lens could also be obtained by means of a slide movable in rotation, since the aforementioned gear train, driven by the rack, is kinematically connected to the roller which allows the flexible polarized glass drive.
