Definitions

  • the patent application CH 709256 A2 describes a timepiece with a retrograde display comprising a single indicator hand capable of being controlled to display, in a first display mode, a first information opposite a first indicator scale and, in a second display mode, a second information opposite a second indicator scale.
  • An external pushbutton allows a user to switch from one display mode to the other.
  • This document merely mentions the use of a "cam and feeler system" to control the movements of the indicator needle, without however providing any concrete clue for the corresponding construction, while the latter is far from being obvious.
  • this patent describes a relatively complex construction for controlling the movements of a prismatic display member, including in particular an index intended to move linearly to display three different predefined information items in three respective display modes.
  • this document provides for the implementation of a synchronization wheel set comprising a pinion connected to the display index, and the movements of which are controlled alternately by three racks carried by three respective levers arranged around the synchronization wheel set, each of which is associated with one of the predefined information items.
  • Each lever is held under stress by a spiral spring and carries a feeler capable of cooperating with the periphery of a specific cam whose angular orientation is a function of the corresponding predefined information item.
  • a selection gear train is provided for controlling the angular orientation of a selection wheel, arranged on the synchronization wheel set, relative to the various levers.
  • the selection wheel has a shape such that it can cooperate with the levers sequentially, so that only one lever at a time can be in an active state, in which its feeler is positioned in abutment against the corresponding cam, under the effect of its spiral spring, and its rack is engaged with the pinion, to control the movements of the latter according to the angular orientation of the cam.
  • the selection wheel cooperates with the other two levers to keep them in an inactive state, in which their rakes are out of range of the pinion and their feelers are out of range of the corresponding cams.
  • This construction has a significant overall size, both in plan, with the central location of the synchronization wheel and the distribution of the levers and their spiral springs around it, as well as with its complex display train, and in the direction of the thickness, in particular because of the structure of the synchronization wheel and all its numerous stages, necessary to ensure its proper functioning.
  • the mode of cooperation chosen between the synchronization wheel and the various levers requires great precision in the manufacture and assembly of the various components involved, without any possibility of adjustment after assembly, in particular with regard to the selection wheel. It will be noted more specifically the fact that perfect synchronization is required in the operations of meshing and uncoupling the various racks with the central pinion when changing the display mode.
  • a main object of the present invention is to propose a display mechanism, making it possible to control two display members so that each of them can alternately display two different pieces of information, of a construction different from that of known display mechanisms, and which has a reasonable size and limited manufacturing and assembly complexity.
  • each of the drive members comprises a feeler intended to be positioned in support against the corresponding cam in its active state, under the effect of the action of an elastic member.
  • the selection member is arranged and shaped in such a way that the changes of state of the first drive member and the first additional drive member, respectively of the second drive member and the second additional drive member, are synchronized.
  • Such an arrangement of the selection organ, around the mobiles of the display mechanism makes it possible to significantly reduce the total thickness of the display mechanism and to simplify its construction, in particular by limiting the number of levels in which these mobiles are distributed.
  • the selection cam cooperates with each of the drive members, to move it and maintain it in its inactive state, by means of a corresponding rocker, partially elastically deformable.
  • the change from the inactive state to the active state of a given drive member necessarily involves the prior change from the active state to the inactive state of the other drive member associated with the same counter wheel set, which makes it possible to eliminate any risk of conflict between the teeth likely to cooperate with this counter wheel set.
  • the actuation of the mobile jumpers, at each step of the selection member makes it possible to guarantee the locking of the counter wheels during changes of display modes, during the transition phases during which none of the drive members are engaged with them, in other words when all the drive members are simultaneously in the inactive state.
  • one of the cams associated with one of the counter mobiles and one of the cams associated with the other of the counter mobiles together define a pair of coaxial cams.
  • coaxial display mobiles it can also be provided that the pair of coaxial cams is coaxial with them.
  • the selection organ carries indications intended to be visible from the outside of a timepiece housing the watch movement, to indicate at any time, to a user, on the basis of which information the counter mobiles are driven, among the predefined information.
  • the present invention also relates to a watch movement comprising a display mechanism according to the preceding characteristics.
  • the watch movement according to the invention comprises at least two drive mobiles arranged to drive the first and second cams and first and second additional cams, in such a way that at least two of them can be driven in rotation with different angular speeds.
  • the present invention also relates to a timepiece comprising a watch movement according to the preceding characteristics.

Furthermore, the timepiece is deliberately presented here in a basic form for the same sake of simplification, and the person skilled in the art will not encounter any particular difficulty in adapting the present teaching according to his own needs, and in producing a timepiece whose elements not directly related to the implementation of the invention may differ from those presented here, without departing from the scope of the invention as defined by the appended claims.
  • the display mechanism 2 is shown here in the form of a display module superimposed on a watch movement or base caliber (not visible), but it could also be integrated directly into the watch movement, as an alternative, without departing from the scope of the present invention as defined by the attached set of claims.
  • the display mechanism 2 comprises first and second display mobiles 4, 6, coaxial here and arranged at the center of the watch movement by way of non-limiting illustration.
  • Each of the display mobiles 4, 6 is intended to carry a display member 8, 10 taking the form of an indicator hand here by way of non-limiting illustration.
  • the display members 8, 10 can be driven from the watch movement, via the display mechanism 2, to indicate respectively the current hours and the current minutes.
