Definitions
- the present invention relates to a mechanical movement comprising a device for displaying information, such as information related to time, for example the time, comprising at least one member indicating said information mounted pivoting around an axis of pivot a.
- the present invention also relates to a timepiece comprising such a mechanical movement.
- Devices for displaying information can be, in a conventional manner, of the analog display type.
- These traditional hand-fitting display devices use a hand for displaying the hours and a hand for displaying the minutes, these two hands moving, while pivoting around the same axis, facing a dial bearing hour and minute graduations with which they cooperate to display the time.
- a seconds hand can complete the display.
- the hour and minute hands are pierced with a hole, allowing the fixing of the hour and minute hands on the barrel of the hour wheel and the roadway respectively, positioned under the dial.
- the hour and minute hands are therefore driven in rotation by the hour wheel and by the road respectively via a portion of the hand which passes through the axis of rotation common to the two hands.
- the distal end of each hand constitutes the indicator part intended to cooperate with the graduations of the dial.
- This well-known display device however has the disadvantage of occupying a large volume, in particular in the direction of the thickness of the movement, due to the stacking of the various components and the number floors needed. Therefore, 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 switching display device therefore cannot be used in an ultra-flat mechanical timepiece.
- Ultra-flat display solutions have been proposed, for example in patent CH 694786, using a display device comprising a central disc for displaying the hours and an outer ring for displaying the minutes, concentric with the disc of the hours.
- the disc 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 as being cut in the center, seeming to be hidden by the central disc. It is therefore not possible to use a traditional hand-type display, with the two hour and minute hands appearing rotated on the same axis in the center of the display.
- solid disks has certain drawbacks, in particular a certain inertia.
- the mass of the solid discs being important, a great energy is necessary for their movement. This can cause difficulties in guaranteeing the maintenance of the very small gap between the solid discs when the watch undergoes, for example, unexpected shocks.
- the use of solid discs made of transparent material has the further disadvantage of creating a parallax problem occurring when viewed obliquely with respect to the display device. Indeed, the stacking of one or more transparent discs with the glass accentuates the parallax effect, which can thus distort the accuracy of the reading.
- the present invention aims to remedy these drawbacks at least in part by proposing a device for displaying information making it possible to produce an ultra-thin mechanical watch movement.
- the invention proposes in particular a device for displaying several pieces of information arranged to indicate the time in the manner of a traditional switch, while being able to be used in an ultra-thin mechanical watch movement.
- the invention relates to a mechanical movement comprising a device for displaying an indication comprising at least one member indicating said information mounted pivoting around 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 wheel set arranged to pivot coaxially to the pivot axis A and comprising external peripheral toothing, said wheel set being housed in the cavity and arranged to carry said indicator member.
- said mobile comprises a rim comprising said outer peripheral toothing and defining an interior opening, said rim carrying an arm radially passing through said interior opening to be pivotally mounted on said pivot axis A, the indicator member being represented on said arms.
- 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 size 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 a perforated mobile that does not require significant energy to be set in motion. It also does not cause parallax problems, even when several mobiles of the same type are superimposed.
- the display device may comprise at least a first member indicating first information and a second member indicating second information pivotally mounted about the pivot axis A and disposed 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 wheel set arranged to pivot coaxially with the pivot axis A and comprising a first outer peripheral toothing, said first wheel set 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 with the pivot axis A, and comprising a second rim comprising a second outer peripheral toothing and defining a second interior opening through which the first indicator member can appear, said second rim carrying a second arm passing radially through said second opening to be pivotally mounted on said pivot axis A, the second indicator member being represented on said second arm.
- said first mobile is a solid wheel comprising said first outer peripheral toothing, and on which the first indicator member is represented.
- said first mobile comprises a first rim comprising said first outer peripheral toothing and defining a first internal opening, said first rim carrying a first arm radially passing through said first opening to be pivotally mounted on said pivot axis A, the first indicator member being represented on said first arm.
- the display device can comprise at least a third indicator member of a third item of information placed in the cavity, superposed on said second indicator member, said third indicator member being pivotally mounted around 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 housed in the cavity, arranged to pivot coaxially with the pivot axis A and comprising a third serge comprising a third outer peripheral toothing and defining a third internal opening through which the first and second indicator members can appear, said third serge carrying a third arm passing radially through said third opening to be pivotally mounted on said pivot axis A, the third indicator member being represented 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 pivotally mounted 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 organ.
