Definitions

  • the present invention relates to a timepiece comprising a watch movement, provided with an analog display comprising at minus two rotary display indicators secured to coaxial guns respective and of means for locating the angular position of these indicators.
  • the invention relates identification of the angular position of each indicator by a plate rotating superimposed on a magnetic or capacitive detector.
  • the object of the invention is to provide a timepiece of the type defined in preamble, and in which several coaxial display indicators can be associated with means capable of providing information to their respective angular positions, while solving the problems that come to be stated.
  • the subject of the invention is therefore a timepiece as defined by the features of claim 1.
  • the presence of several sensors, associated with as many coaxial indicators does not increase the height of the timepiece, which remains essentially the same as that which we would have with identification by a single indicator rotating on a given axis. Moreover, he becomes possible to arrange the position marking plates at a first level and the sensors on a second level, so the markup in height possibly necessary for the identification of the angular positions of coaxial indicators remains that of a single sensor.
  • sensors located on the same level preferably, all of the connections can also be carried out at the same level, i.e. from the base of the sensors.
  • FIGS 1 and 2 represent a first embodiment of the timepiece according to the invention.
  • She includes 1 minute cannon and 2 hour cannon mounted coaxially, in a conventional manner, on a common post 3 of axis 4.
  • Des 5 and 6 hour rotary indicators are respectively hunted on cannons 1 and 2.
  • indicators 5 and 6 can also indicate other quantities such as the second, timing data, date, etc. he it is also conceivable to provide, in a coaxial position, more than two display indicators, all provided with means for identifying their angular position designed according to the invention.
  • the tree 3 is inserted in a bridge 7 of the movement of the timepiece, this bridge being here applied against a wafer 8 which is preferably an insulating substrate capable of advantageously carry a printed circuit connecting the components together electrical and electronic parts of the timepiece.
  • a wafer 8 which is preferably an insulating substrate capable of advantageously carry a printed circuit connecting the components together electrical and electronic parts of the timepiece.
  • Its timepiece circuit (not shown) can optionally be arranged above.
  • the minute cannon 1 carries a first plate 9 for locating its angular position arranged perpendicular to the axis 4.
  • this tray includes four openings 10, distributed with a angular offset of 90 ° between them. As seen in Figure 2 these openings 10 are separated by branches of material 9a. So the cannon minutes 1 and its associated tray 9 together form a first mobile position marker, which has been assigned the reference MR1 and which contributes when obtaining position information from the minute indicator 5.
  • This timepiece also includes a first sensor 11 of magnetic or capacitive type. It is placed near the plate 9 and includes a detection element 12. The latter is placed below the platform 9 directly above an area in which the openings 10 and the material branches 9a of this plate separating the openings to each other. The alternating presence of these openings 10 and of these branches of material 9a above the detection element 12, is capable of causing the production of a signal representative of the position angular of the latter in particular for the presence of a wider arm.
  • the detection element 12 is a induction coil sensitive to variations in electromagnetic properties of the plate 9, when it rotates around the axis 4. It can therefore be seen that the plate 9 has at least one discontinuity of material capable of being detected by the sensor 11, during the rotation of the mobile MR1 relative to said sensor 11, to provide a first measurement signal representative of a angular position of the display indicator 5.
  • the timepiece according to the invention also comprises a second position locating mobile MR2 mounted away from mobile MR1.
  • This the latter comprises a journal 13 mounted rotatably, in the bridge 7 and in a plate 14 of the timepiece, around an axis 15.
  • the 2 hour cannon meshes through its plate 16, with a drive plate 17 riveted on the pin 13 and, therefore, attached to the hour indicator in rotation 6.
  • the gear ratio between the plate 16 driven by the 2 hour cannon and the plate drive 17 is preferably 1: 1.
  • a second plate 18 for locating angular position is also riveted on the pin 13 in a position perpendicular to the axis 15.
  • this plate 18 has a shape identical to that of the plate 9, with the exception of the toothing, and therefore has separate openings 19 by radial branches of material 18a. Note however that the identity of shapes and diameters of the two plates 9 and 18 is not an imperative.
  • the second position marker MR2 thus contributes to obtaining position information from the hour indicator 6 in association with a second sensor 20 placed near the second plate 18 and comprising a detection element 21.
  • the latter is placed in below the plate 18, plumb with an area in which evolve alternately the openings 19 and the branches of material 18a separating the openings of each other.
  • the alternate passage of these openings 19 and of these branches of material 18a above the sensor 20 is capable to cause the production by said sensor 20 of a signal representative of the angular position of the mobile MR2 and, consequently, of the hour indicator 6.
  • the detection element is a coil induction sensitive to electromagnetic variations of the plate 18, when turns around the axis 15. It can therefore be seen that the second plate 18 contains at least one discontinuity of material capable of being detected by the second sensor 20 when the mobile MR2 rotates relative to this sensor, to provide a second measurement signal representative of a position angle of the second display indicator 6.
  • the sensors 11 and 20 can be inductive (as shown here) or type capacitive.
  • the plates 9 and 18 are shaped in such a way and made in a material such that their movements relative to the sensors generate respectively variations of at least one parameter of these, these variations giving rise to the formation of the aforementioned position signals.
  • This general formulation implies that many possibilities of realization tray-sensor pairs are possible within the scope of this invention, these possibilities resulting for the skilled person in particular from aforementioned patent applications. The description of these many variants is therefore not repeated here.
  • Each of the detection elements 12 and 21 is mounted on a substrate 22 and 23 also carrying, for example in the form of an integrated circuit, the means for electronic processing of the signal supplied by the detection element 12 or 21 associated.
  • the substrates 22 and 23 are made of a material semiconductor. If, as in the embodiment shown in the Figures 1 and 2, the detection elements 12 and 21 are flat coils, they are preferably formed by metallic deposition on their substrates respectively 22, 23. In addition, each of them may include wires of connection 24 leading to another arranged electronic operating circuit in the timepiece, including in particular the timepiece circuit. Glue drops 25 can partially or preferably coat totally these sons.
  • the position marking plates 9 and 18 and their associated sensors 12 and 21 are respectively arranged in two superimposed planes parallel to the substrate 8.
  • the height occupied by the set of two plate-sensor pairs is limited to that of only one of these couples as opposed to a layout where the two sets would superimposed along axis 4, in particular with a sensor arranged between the plates 9 and 16.
  • the mobile MR2 in addition to its position tracking function, a force transmission function to the associated indicator 6 within the framework of the watch movement proper.
  • the plate 18 of the mobile MR2 can be part of a work engine gear train watchmaking (or be driven directly by a motor) to ensure the transmission of the movement towards the plate 16 of the hour canon 2.
  • the plate 18 has teeth.
  • the force transmission can be provided by the drive plate 17 of the mobile MR2 making, in this case, part of the gear train of the timepiece. We can then dispense a toothing on the plate 18.
  • the plate 16 of the hour canon 2 can be driven directly by a motor gear train (or by a motor) of the timepiece and in turn drive the mobile MR2 by via tray 17.
  • the mobile MR2 is a mobile additional dedicated only to locating the angular position of indicator 6.
  • a driving force is applied to the mobile MR1 by the plate 9, this comprises a toothing 27.
  • the barrel 1 minutes can be driven for example at a pinion located above or below the plate 9.
  • FIGS. 3 and 4 show another embodiment of the part of watchmaking according to the invention differing from that of FIGS. 1 and 2 only by the arrangement of the detection elements and their associated circuits. Others components of the part will therefore not be described again and they bear the same references as in FIGS. 1 and 2.
  • sensors 11A and 20A include detection elements 12A and 21A which, in this example, are also in the form of flat inductive coils. But here the electronic circuits of the two sensors 11A and 20A are provided in the same semiconductor substrate 28. From these two circuits preferably have a common part integrated in this substrate. In this case, it may also be advantageous to integrate into the substrate 22 all of the electronic components of the timepiece, including the timepiece circuit.
  • the substrate 28 extends, by a part end carrying the detection elements 12A and 21A, between axes 4 and 15 of the mobiles MR1 and MR2, in the variant of FIG. 5, there is provided a substrate 29 extending through a corner portion 29a between axes 4 and 15, in thus being placed at an angle.
  • FIG. 6 shows a substrate 30 placed entirely on the same side compared to axes 4 and 15, this variant being expensive given the surface significant of the semiconductor substrate required.
  • the plates 9 and 18 are plumb as respective detection elements 12B and 21B, for example of separate coils arranged either directly on a bridge or the plate of the timepiece, or on another support, these coils being connected to an electronic circuit 31 by wires 32, the circuit 31 being provided away from the plates 9 and 18.
  • the detection elements 12B and 21B are inductive coils formed by an electric wire comprising several turns increasing the detection sensitivity. This last variant makes it possible to reduce the thickness of the part as much as possible of watchmaking, while ensuring good sensitivity for detecting means for locating the angular positions of the analog indicators for a low cost.
