Definitions

  • the present invention relates to a mechanical movement comprising a device for displaying information, such as time-related information, for example the time, comprising at least one indicator member for said information mounted to pivot about a pivot axis A.
  • the present invention also relates to a timepiece comprising such a mechanical movement.
  • Devices for displaying information may be, in a conventional manner, of the analog display type.
  • These display devices with traditional handing use a hand for displaying the hours and a hand for displaying the minutes, these two hands moving, by pivoting around the same axis, opposite a dial bearing graduations of the hours and minutes with which they cooperate to display the time.
  • a second hand may complete the display. Substantially at one of their ends, the hour and minute hands are pierced with a hole, allowing the hour and minute hands to be fixed on the barrel of the hour wheel and the cannon-pinion respectively, positioned under the dial.
  • the hour and minute hands are therefore rotated by the hour wheel and by the cannon-pinion respectively via a portion of the hand which passes through the axis of rotation common to the two hands.
  • the distal end of each needle constitutes the indicator part intended to cooperate with the graduations of the dial.
  • This well-known display device has the disadvantage of occupying a significant volume, particularly in the direction of the thickness of the movement, due to the stacking of the different components and the number of necessary stages.
  • the volume available inside the case in which the movement is positioned must be large enough to accommodate, in addition to the movement, a dial placed above the movement and the hands positioned above the dial.
  • This traditional hand-operated display device cannot therefore be used in an ultra-thin mechanical timepiece.
  • Ultra-flat display solutions have been proposed, for example in the patent CH 694786 , using a display device comprising a central disk for displaying the hours and an outer ring for displaying the minutes, concentric with the hour disk.
  • the disk and the ring carry indexes moving in rotation opposite a dial bearing graduations, at appropriate speeds, to display the time.
  • the minute index necessarily appears to be cut off in the center, appearing to be hidden by the central disk. It is therefore not possible to use a traditional pointer type display, with the two hour and minute hands appearing pivoted on the same axis at the center of the display.
  • a solution described in the patent FR 2 461 292 has been proposed to produce an extra-flat electronic watch. It is proposed to position an hour disc and a minute disc in the back of the watch, used as a plate, these discs being transparent solid discs on which are provided markers acting as hour hands and minute hands.
  • the thick elements of the watch such as the motor, the quartz and the battery, are installed outside the field of the display discs, in housings made between the back and the caseband-bezel, so as to obtain an extra-flat watch.
  • the arrangement of the different parts of a mechanical watch is more complex than that of an electronic watch.
  • the use of solid discs has certain drawbacks, in particular a certain inertia.
  • the mass of the solid discs is significant, a great deal of energy is required to set them in motion. This can cause difficulties in ensuring that the very small gap between the solid discs is maintained when the watch is subjected to unexpected shocks, for example.
  • the use of solid discs made of transparent material has the further disadvantage of creating a parallax problem occurring when viewing at an angle to the display device. Indeed, stacking one or more transparent discs with the glass accentuates the parallax effect, which can thus distort the accuracy of the reading.
  • the document EP 2 791 738 A1 discloses a mechanical movement comprising time information display discs comprising at least one indicator member.
  • the present invention aims to remedy at least in part these drawbacks by proposing a device for displaying information making it possible to produce an ultra-flat mechanical clockwork movement.
  • the invention notably proposes a device for displaying several items of information arranged to indicate the time in the manner of a traditional hand, while being able to be used in an ultra-flat mechanical watch movement.
  • the invention relates to a mechanical movement comprising a device for displaying an indication comprising at least one indicator member of said information mounted to pivot about a pivot axis A, said movement enclosing a cavity receiving at least said first indicator member, said cavity being arranged so that said indicator member is housed entirely inside the movement, said movement comprising at least one mobile arranged to pivot coaxially with the pivot axis A and comprising external peripheral teeth, said mobile being housed in the cavity and arranged to carry said indicator member.
  • said mobile comprises a rim comprising said external peripheral toothing and defining an internal opening, said rim carrying an arm radially passing through said internal opening to be pivotally mounted on said pivot axis A, the indicator member being shown on said arm.
  • Such a construction makes it possible to advantageously eliminate the conventional drive via the barrel of an associated drive wheel which passes through the pivot axis, and which represents a significant bulk. It advantageously allows a gain in height, making it possible to reduce the bulk of the display device.
  • the indicator organ is entirely integrated inside the mechanical movement, and does not come out of the volume occupied by said movement as such, and more particularly in the direction of the thickness of the movement. With such a movement, it is therefore possible to produce an ultra-flat mechanical timepiece, the available interior volume of the case being barely larger than the volume occupied by the movement integrating the display device.
  • the mobile bearing the indicator member used in the present invention makes it possible to have an openwork mobile that does not require significant energy to be set in motion. It also does not cause any parallax problems, even when several mobiles of the same type are superimposed.
  • the display device may comprise at least a first indicator member for a first piece of information and a second indicator member for a second piece of information mounted to pivot about the pivot axis A and arranged in said cavity, said second indicator member being superimposed on said first indicator member, said cavity being arranged so that said first indicator member and said second indicator member are housed entirely inside the movement, and the movement comprises a first mobile arranged to pivot coaxially to the pivot axis A and comprising a first external peripheral toothing, said first mobile being housed in the cavity and arranged to carry said first indicator member and a second mobile housed in the cavity, arranged to pivot coaxially to the pivot axis A, and comprising a second felloe comprising a second external peripheral toothing and defining a second internal opening through which the first indicator member can appear, said second felloe carrying a second arm radially passing through said second opening to be pivotally mounted on said pivot axis A, the second indicator member being shown on said second arm.
  • said first mobile is a solid wheel comprising said first external peripheral toothing, and on which the first indicator member is represented.
  • said first mobile comprises a first felloe comprising said first external peripheral toothing and defining a first internal opening, said first felloe carrying a first arm radially passing through said first opening to be pivotally mounted on said pivot axis A, the first indicator member being shown on said first arm.
  • the display device may comprise at least one third indicator member for a third piece of information arranged in the cavity, superimposed on said second indicator member, said third indicator member being mounted to pivot about the pivot axis A, said cavity being arranged so that said third indicator member is housed entirely inside the movement with the first and second indicator members, and the movement comprises a third mobile member housed in the cavity, arranged to pivot coaxially with the pivot axis A and comprising a third felloe comprising a third external peripheral toothing and defining a third internal opening through which the first and second indicator members can appear, said third felloe carrying a third arm radially passing through said third opening to be pivotally mounted on said pivot axis A, the third indicator member being shown on said third arm.
  • inventions are particularly suitable for displaying the time, for example, the first indicator member displaying the hours, the second indicator member, superimposed on said first indicator member, displaying the minutes, the possible third indicator member, superimposed on said first and second indicator members, displaying the seconds, being mounted pivoting about said pivot axis A, and the cavity is arranged so that said second indicator member and the possible third indicator member are housed entirely inside the movement, with the first indicator member.
  • the present invention also relates to a timepiece comprising a mechanical movement as defined above.
  • the present invention relates to a mechanical watch movement comprising a device for displaying information, in particular information related to time, such as seconds, minutes or hours, these different pieces of information being able to be used individually or by combining at least the hours and minutes to indicate the current time.
  • a watch movement is the mechanical part of a timepiece comprising all the organs and mechanisms which are used to determine the time (the main ones being the motor, the gear train, the escapement and the regulating organ), carried by a frame.
  • the movement is intended to be arranged in a case, called a watch case, with the display device, to constitute the timepiece.
  • the movement 1 occupies a volume which is symbolically represented on the Figures 1 to 6 by a closed, ultra-flat cylinder, so as to represent an ultra-flat movement.
  • the various organs and mechanisms making up the mechanical watch movement are known to those skilled in the art, and are not shown.
  • the display device 2 comprises at least a first indicator member 4 of a first piece of information, such as the time for displaying the time, and a second indicator member 6 of a second piece of information, such as the time for displaying the time, and a second indicator member 6 of a second piece of information.
  • information such as the minute to display the minutes, superimposed on the first indicator member 4, that is to say placed in front of the first indicator member 4 for a user looking at the movement 1.
  • the display device 2 is advantageously a device for displaying the current time HH.MM.
  • Each indicator member 4, 6 is pivotally mounted about the same pivot axis A passing through the center of the display device 2.
  • Each indicator member 4, 6 is represented by a hand having, at one end, a hole 7 through which the pivot axis A passes and, at the other end, a point directed towards the outside of the movement 1.
  • the indicator members 4, 6 appear as a set of hands arranged at the center of the display device 2 to indicate the current time, in a traditional manner.
  • the movement 1 contains a cavity 8 receiving here the first and second indicator members 4, 6, said cavity being arranged so that said first and second indicator members 4, 6 are housed entirely inside the movement 1. More particularly, the cavity 8 has in particular a depth, that is to say in the direction of the thickness of the movement 1, chosen so that the first and second indicator members 4, 6 remain inside the volume occupied by the movement 1, whatever their display position.
  • Said cavity 8 is at least open on the side of the movement on which the display device 2 must be visible to the user.
  • the bottom of the cavity 8 can be closed.
  • the cavity 8 can be formed by a hollow provided in the plate of the movement for example.
  • the cavity 8 can be through, able to reveal the movement under the display device, as in the embodiment shown in the Figures 1 and 2 . This can be particularly useful for making a skeleton watch.
  • the through cavity 8 can be formed for example by arranging the various organs and mechanisms of the movement arranged relative to each other so as to constitute said cavity inside the movement.
  • the movement 1 can be closed by an open plate at the cavity 8, so as to leave visible only the indicator organs 4, 6 of the display device 2.
  • Fixed time indications can be provided on this plate, to cooperate with the indicator organs 4, 6, to display the hours and minutes, like a dial. In the case of a skeleton watch, the movement is left open.
  • the display device 2 In order to be able to be housed entirely inside the movement 1, the display device 2 must have a reduced thickness.
  • At least one of the first and second indicator members, and preferably the first and second indicator members 4 and 6, are advantageously arranged to be driven in rotation about the pivot axis A by an external peripheral zone which does not pass through said pivot axis A.
  • Driving the indicator members 4, 6 from the outside advantageously makes it possible to eliminate the different stages imposed by the traditional construction of the cannons of the hour wheel and the cannon-pinion, and thus to reduce the thickness of the assembly.
