Definitions

  • the present invention relates to a timepiece comprising a body forming box inside which is housed a watch movement, this body having at least two distinct faces on which are respectively arranged first and second display means driven by the movement watchmaker.
  • a timepiece comprising first and second boxes (an upper box and a lower box) mounted pivoting relative to each other about a substantially perpendicular pivot axis in the general plan of boxes. Both boxes can occupy a first position closed where the upper box is superimposed on the lower box and hides the face before the lower box, and a second open position where the upper box is rotated relative to the lower box to discover the front. It's about however here a timepiece where the upper box has a movement watchmaker and associated means for displaying the time and where the lower box has a compass. It will be understood that the watch movement is fully mounted in the upper box and is totally independent of the mechanism housed in the lower box, namely the compass.
  • a general object of the present invention is to propose a solution allowing, like the previous solutions, to exploit a larger surface on the timepiece to equip it with a wide range of display means, while ensuring however a great simplicity of handling, especially avoiding the need to return the body forming box.
  • Another object of the present invention is to propose a solution which requires a unique watchmaking movement that can otherwise be entirely realized in mechanical form.
  • the subject of the present invention is a timepiece whose features are set forth in claim 1.
  • the body forming the box of the timepiece thus comprises a first box, said upper box, having a front face carrying the first means display and a second box, said lower box, having a front face carrying the second display means.
  • These boxes are mounted pivoting one by relative to the other about a pivot axis substantially perpendicular to the plane general boxes and can occupy a first position, called closed, where the box upper is superimposed on the lower box and mask at least partly the face before the lower box, and a second position, called open, where the box upper is rotated relative to the lower box to discover at least one part of the front side.
  • the watch movement includes first and second parts housed respectively in the upper and lower boxes to drive the first and second display means, respectively, and a mechanism of training ensuring a kinematic connection between the first and second parts of the watch movement.
  • This drive mechanism is arranged to ensure an interruption of the kinematic link between the first and second parts of the watch movement when the boxes are brought into position opened.
  • the watch movement is subdivided into two parts which are respectively housed in the upper and lower boxes, the drive mechanism being provided to ensure a kinematic connection between these two parts of the movement watchmaker and to interrupt this kinematic link when the boxes are brought into open position.
  • the drive mechanism comprises an axis transmission mobile confused with the pivot axis of the boxes, this transmission mobile comprising a first end emerging in the upper box and a second end emerging in the lower box.
  • the boxes are brought into open position by rotation of the upper box relative to the box lower in a first determined direction of rotation and the transmission mobile is rotated by the watch movement in a second direction of rotation opposite to the first direction of rotation, the drive mechanism being arranged to interrupt the rotational drive of the mobile transmission when the boxes are brought into open position and to restore the rotation of the mobile transmission when the boxes are brought back in the closed position.
  • the mechanism of training is moreover arranged to make up for a synchronism error (or delay) between the first and second display means when the boxes are brought back to the closed position.
  • the timepiece further comprises a retaining element of essentially tubular shape, of axis coinciding with the axis of pivoting boxes and crossed by the mobile drive aforementioned, this retaining element being secured to one of the boxes and now axially the other box along the pivot axis while allowing rotation of this other box relative to the retainer.
  • FIGS. 1a to 1c generally illustrate a timepiece presenting itself in the general form of a wristwatch and constituting an embodiment of the present invention.
  • the body forming the box of the room timepiece consists of two boxes 1 and 2, respectively designated box upper and lower box, each carrying on their front face means of displays generally designated by reference numerals 16 and 26 respectively.
  • These two boxes 1, 2 are likely to pivot one with respect to the other around a pivot axis, designated X, substantially perpendicular to the general plan of the two boxes 1 and 2.
  • the boxes upper 1 and lower 2 can occupy a first position, said closed, (not shown) where the box upper 1 is superimposed on the lower box 2 and hides the front face of this box, and a second position, said open, (position shown in FIGS. 1a 1c) where the upper box 1 is rotated relative to the lower box 2 to discover at least part of the front face where are the display means 26.
  • the lower box 2 is conventionally provided with horns 4 to allow the attachment of a bracelet represent.
  • the upper box 1 is in turn conventionally provided with a crown rod 3 to allow the time setting of the timepiece.
  • Ways display 16 arranged on the front face of the upper box 1 conventionally include needles of the hours and minutes arranged in the center and supplemented by other indicators, for example a seconds indicator or a power reserve indicator.
  • the display means 26 formed on the front face of the lower box 2 (under a second ice designated by reference numeral 25) include in particular a moon phase indicator and a date indicator. These second display means 26 are generally arranged in off-center position on the front of the lower box 2.
  • the needles of hours and minutes may for example be arranged on the front face of the lower box 2.
  • These needles will typically be placed on the box in which the source is housed. of mechanical energy (barrel and mainspring) as well as the regulating the movement of the timepiece (balance spring and escapement), these parts can be arranged independently in the upper box 1 or lower 2.
  • mechanical energy barrel and mainspring
  • balance spring and escapement the regulating the movement of the timepiece
  • the watch movement is, strictly speaking, divided into two parts (no represented in FIGS. 1a to 1c) housed respectively in the boxes upper and lower 2 (these parts are hereinafter referred to generally as numerals 100 and 200 respectively), a drive mechanism being provided to ensure a kinematic connection between these two parts of the movement.
  • This mechanism of training will be described in more detail in the following this description.
  • this one can a priori be arranged in any suitable point of the timepiece.
  • this pivot point is advantageously disposed to inside the outer periphery of the two boxes 1, 2, no ear or protuberance unsightly being thus apparent on the periphery of the boxes.
  • the pivot axis X is essentially in the quadrant included between noon and three o'clock (here at approximately two o'clock), the second 26 being slightly eccentric to the lower left of the face before the lower box 2.
  • the boxes 1, 2 are brought into the open position by rotation of the upper box 1 in a direction of rotation determined around the axis of X.
  • This direction of opening is indicated in Figure 1b by an arrow bearing the reference A, this sense of opening being here counter-clockwise (by convention this direction of rotation is defined around the pivot axis X, display means 16, 26 directed forward).
  • the upper box 1 is rotated about 180 ° with respect to its closed position where it is superimposed on the lower box 2.
  • a rotation limiting mechanism is preferably provided to guide the boxes 1, 2 and limit their opening angle.
  • FIG. 2 shows a partial sectional view of the illustrated timepiece in FIGS. 1a to 1c passing through the pivot axis X of the boxes 1, 2. found the upper box 1, formed of a bezel 11 carrying the ice 15 adjusted on a bottom portion 12, and the lower box 2, formed analogously of a bezel 21 carrying the ice 25 fitted to a bottom portion 22.
  • Figure 2 also shows a portion of a dial 17 disposed under the window 15 and facing which turn the hands of the first display means 16.
  • the seal between the bezel 11 and the bottom 12, and between the bezel 21 and the bottom 22 is ensured typically by a seal 13, respectively 23, arranged in a groove formed on the bottom 12, resp. 22.
  • the bottom 12 of the upper box 1 and the bezel 21 of the lower box 2 comprise an opening arranged to allow the passage of the mechanism drive ensuring the kinematic connection between the two parts 100, 200 of the watch movement.
  • This training mechanism is designated globally by the reference numeral 5 and is illustrated in greater detail in FIGS. 4a and 4b which will be discussed below.
  • the drive mechanism 5 comprises in particular a transmission mobile 51 which one end emerges in the upper box 1 and another end emerges in the lower box 2.
  • the pivoting and the mechanical connection between the upper boxes 1 and 2 are preferably provided by means of a shape retaining member tubular 30 whose axis coincides with the axis of pivoting X boxes 1, 2 and through which passes the transmission mobile 51.
  • This retaining element 30 is made integral with one of the boxes (here the upper box 1) for example by screwing, as illustrated, or by any other suitable means.
  • the element of retainer 30 thus has a threaded end 30a cooperating with a tapping arranged in the bottom 12 of the upper box 1.
  • the lower box 2 is retained axially along the pivot axis X via a span 30b arranged on the other end of the element 30. In this case, the telescope 21 of the lower box 2 is held axially between the span 30b and the bottom 12 of the upper box 1.
  • the retaining element 30 advantageously forms the inner ring of a ball bearing whose outer rings, designated by the reference numeral 32, is integral with the lower box 2. It will be understood that this configuration makes it possible to reduce the friction between the contact zones of the two boxes during the opening and closing operations of the two boxes. On title alternatively, as illustrated in Figure 3, it is perfectly possible to not make use of a ball bearing and directly provide a radial clearance between the retaining element 30 and the lower box 2.
  • retaining element 30 could alternatively be made integral with the lower box 2 and that the pivoting of two boxes could be ensured by rotation between the retaining element 30 and the upper box 1.
  • FIGS. 2 and 3 From a mechanical point of view and from the point of view of the sealing at the level of the pivot axis X, it is preferable, as illustrated in FIGS. 2 and 3, to arrange on one of the boxes at least one ring-shaped protuberance cooperating with an orifice or an annular groove of corresponding diameter on the other box.
  • the bottom 12 of the upper box 1 is thus provided with such a protuberance designated by the numeral 12a cooperating with a corresponding orifice, designated 21a, formed in the bezel 21 of the lower box 2.
  • the telescope 21 is again provided with a annular protuberance 21b housed in an annular groove corresponding 12b formed in the bottom 12.
  • the seal between the two boxes 1 and 2 is provided by an annular seal 33 radially interposed between the protuberance 12a and the wall of the orifice 21a.
  • This seal ring 33 is in this case arranged in a groove in the wall of the orifice 21a. It is obvious that the annular seal 33 could alternatively be housed in a groove formed around the protuberance 12a.
  • FIG. 2a is a partial sectional view of the timepiece, according to a general cutting plane perpendicular to the pivot axis X along the line of A-A section shown in Figure 2.
  • the retaining element 30 and its threaded end 30a secured to the bottom 12 by screwing as well as the transmission unit 51 of the drive mechanism 5.
  • the ball bearing with its outer ring 32.
  • the base of the retaining element 30 where is provided the span 30b advantageously comprises two side dishes 30c diametrically opposed, the purpose of which is to enable and facilitate the screwing of the retaining element 30 in the bottom 12 of the upper box 1, this operation of screwing being operated here before mounting the bottom 22 of the lower box 2.
  • FIG. 4a we find against the mobile transmission 51 already mentioned whose axis of rotation coincides with the pivot axis X of the boxes 1, 2.
  • FIG. 4a we also indicated by arrow A the direction of rotation followed by the upper box 1 at the opening (by convention, we will consider that the opening is operated then that the display means 16, 26 face the user) and the arrow B, the direction normal rotation of the mobile transmission 51 when it is driven by the watch movement.
  • the drive mechanism 5 further comprises a drive wheel 53, a plate 52 as well as connecting means 55, 56 interposed between the wheel 53 and the plate 52.
  • the drive wheel 53 and the plate 52 are coaxially mounted to the transmission mobile 51 and are arranged with the means link 55, 56 on one end of the transmission wheel 51 located here in the upper box 1.
  • the other end of the transmission mobile 51 is located in the lower box 2.
  • the mobile of transmission 51 is mounted between a bridge 120 of the first part 100 of the movement located in the upper box 1 and a bridge 220 of the second part 200 of the movement in the lower box 2.
  • Numerals 110 and 210 designate additional bridges or plates of the two parts 100 and 200 of the movement.
  • the plate 52 is fixedly secured to the transmission unit 51 while the drive wheel 53 is mounted free to rotate around the mobile of transmission 51. It can be seen here that the drive wheel 53 is held axially between the plate 52 and a bearing (not referenced) formed on the mobile of transmission 51.
  • the drive wheel 53 is permanently engaged with the first part 100 of the watch movement housed in the upper box 1.
  • Figures 4a and 4b only illustrated a drive wheel 105 forming part of the first part 100 of the watch movement with its teeth 105a engaged with the teeth 53a of the drive wheel 53. It will therefore be understood that the drive wheel 53 is continually rotated under the effect of the first part 100 of the watch movement, the drive of this wheel 53 being effected in the direction of the arrow B.
  • the transmission mobile 51 is in direct contact with the second part 200 of the watch movement.
  • the transmission mobile 51 is terminated by a pinion portion 51a in direct engagement with the toothing 205a of a wheel 205 part of the second part 200 of the watch movement located in the box lower 2.
  • connection means 55, 56 between the plate 52 and the drive wheel 53 are arranged so that the plate 52 is normally rotated by the wheel drive 53 when the boxes 1, 2 occupy the closed position and so that the drive in rotation of the plate 52 by the wheel 53 is interrupted when the boxes are brought into position opened.
  • the drive wheel 53 carries a pin 55 disposed in eccentric position with respect to the axis of pivoting X and one end of which is housed in a groove 56 formed in the plate 52 and which has a profile in an arc.
  • the pin 55 could alternatively be placed on the plate 52 and the groove 56 formed on the wheel drive 53.
  • the drive in rotation of the plate 52 by the drive wheel 53 is provided by abutment of the pin 55 against a end of the groove 56 as is clearly illustrated in Figure 4a.
  • the pin 55 When opening and closing the boxes, the pin 55 undergoes a angular displacement corresponding to the opening angle of the boxes in one direction then in the other.
  • the opening and closing operations do not therefore lead to final no delay or loss of synchronism between the first and second means 16 and 26.
  • the delay is due only to the time that has elapsed since the interruption of the kinematic link and this delay is totally caught up during the closing due to the relative angular displacement of the pin 55 relative to the groove 56.
  • the plate 52 and the transmission mobile 51 will undergo a forced angular displacement when closing that is equivalent to the angle opening boxes, that is to say 180 ° in this example.
  • groove 56 is chosen for allow the pin to move when opening the boxes without coming in contact with the other end of the groove 56.
  • the groove 56 has a development angle greater than the opening angle of the boxes 1, 2.
  • the plate 52 and the transmission mobile 51 will be partially driven when opening boxes in a direction of rotation opposite to their normal direction of rotation, which is not advisable.
  • the angle of development of the groove 56 is chosen to be greater than the opening angle of the boxes fixed here at 180 °.
  • the maximum interruption time of the kinematic link between the two parts 100, 200 of the movement depends on the sizing of the mobiles of the movement and drive mechanism 5 and can be fixed at choice to a few minutes or hours. It should be mentioned that the angular displacement forced as well as the constraints on the teeth of the mobiles during the closing are not a real problem.
