Definitions

  • the present invention relates to a timepiece movement intended to equip the case with a reversible watch, and making it possible to display, opposite each of the two main faces of the case, different time information. It relates more particularly to a movement comprising means for indicating in analog form two time information, one on each face of the movement, this information advancing in synchronism with one another, as for example in the case of the display of two different time zones.
  • the present invention aims to fill this gap by providing a movement capable of causing on each of its two main faces, and around the same axis, an analog display of the time.
  • the watch movement according to the invention comprising two main faces that are substantially flat and parallel, mobiles forming a cog arranged to rotate, opposite one of the faces, the hands for displaying the hour around an axis of pivoting arranged perpendicularly to these faces, and means for setting the time of the display, is particularly remarkable in that it also comprises means for driving in rotation, opposite the other main face, the hands another time display from a gear train so that the hands of the other display; rotate around an axis coinciding with the pivot axis in an anticlockwise direction of the display.
  • An advantage of the invention results from the fact that the proposed movement can be obtained by means of a simple and inexpensive transformation of an existing conventional movement, without significantly increasing its thickness.
  • the reference 1 designates a plate, the latter being a thin and flat plate, generally of circular shape.
  • the plate which is delimited by two opposite faces, constitutes the basic element of the movement.
  • the underside of the plate, referenced 2 is intended to receive the dial, not shown, of the watch.
  • the face 2 further supports, in suitable housings 3, cogs, also called mobile, these cogs having the function of rotating the minute hand 4 and that of the hours 5 of the usual analog display of the watch .
  • Other moving parts of the movement are held in place by means of bridges which are fixed on the other face 6 of the plate 1, such as for example the bridge bearing the reference 7.
  • the members which have just been described form part of any conventional analog movement.
  • the face 2 with the members which it supports thus constitutes one of the two main faces, referenced 8, of such a movement, and opposite which the needles 4 and 5 move.
  • the bridges and the face 6 on which they are fixed form the other main face, referenced 9, of this movement.
  • the present invention proposes to describe a transformation of a conventional analog movement making it possible to add to this movement a second analog display of the time, the hands 4 ′ and 5 ′ of this display moving, opposite the main face. 9 of the movement and of another dial not shown, in synchronism with hands 4 and 5 of the usual display, or first display.
  • the movement can be that of a wristwatch, a pocket watch, or a pendant watch.
  • the two displays comprising similar elements, the main elements of the first display, known from the prior art, will first be described.
  • the reference 15 thus designates a shaft which pivots in the plate 1 and the bridge 7 of the movement, and on which is driven a center pinion 16, this pinion supporting on its side a toothed wheel of center referenced 17.
  • the shaft 15, called center shaft or minute tree rotates at the rate of one revolution per hour around a pivot axis aa 'arranged perpendicular to the main faces 8 and 9 of the movement.
  • the pinion 16 meshes with a barrel, not shown, which provides the movement with the torque necessary for its operation.
  • the wheel 17 meshes, for its part, with a train not shown, the speed of rotation of which is stabilized by a spiral balance.
  • the shaft 15 could just as easily, in the case of an electronic quartz movement, be that of a stepping motor.
  • the shaft 15 projects from each of the two main faces of the movement.
  • a hollow cylindrical member 18 pivoting about the axis aa 'and which is called lanterned roadway.
  • the roadway has at one end a pinion 19 which is disposed in a housing 20 of the plate 1. It further comprises in its middle a groove 21 intended to weaken its wall which is pinched, at a location 21a, so that its inner face, coming into contact with a corresponding conical part 15a of the shaft 15, creates a friction torque depending on the gripping force.
  • the free end of the roadway 18 has a cylindrical part 22 of reduced diameter, called the minute cannon, and on which the needle 4 is driven.
  • the pinion 19 of the roadway 18 meshes with a timer wheel 23 which pivots about an axis bb 'on a shaft 24 driven into the plate 1.
  • a timer pinion 25 which meshes with a wheel of the hours 26.
  • the diameters of the wheels 23 and 26 and of the pinions 19 and 25 are chosen so that the wheel 26 rotates 12 or 24 times slower than the minute shaft 15 and can thus be used to indicate the hours.
  • the wheel 26 has in its center a tubular part 27, called the hour cannon, which is arranged on the roadway 18 so as to pivot around the axis aa ', and on which the needle 5 is fixed.
  • the movement further comprises a conventional time-setting mechanism, not shown, which is controlled by a time-setting rod when the latter occupies a determined axial position.
  • the mechanism is a cog which meshes with the pinion 19 of the roadway 18 in order to allow the needles 4 and 5 to be moved quickly when a sufficient torque is applied to the time-setting rod to overcome the friction between the roadway 18 and the minutes tree 15.
  • the setting of the hands 4 'and 5' of the second time display from the minute tree 15, is obtained by means of a return mechanism constituting the present invention and which will now be described.
  • the reference 30 designates in FIG. 1 a shaft of this mechanism, this shaft traversing the movement right through so as to pivot around an axis cc 'arranged perpendicular to the faces 8 and 9.
  • the shaft 30 is supported on the side of the face 8 of the movement by an existing timer bridge 31, and on the side of the face 9, by a complementary bridge 32.
  • the bridge 32 is fixed to the movement by means of the screws 33 and 34, shown in FIG. 2, the first being screwed into a support 35 integral with the bridge 7.
  • On the shaft 30 is driven, on the side of the face 8, a toothed wheel 36 which meshes with the timer wheel 23. This meshing is symbolically represented on the fig.
  • the roadway 37 further comprises a pinion 39, disposed in a housing of the plate 1 on the side of the face 8 of the movement, and a toothed wheel 40, of same diameter as the wheel 36, placed between the bridges 7 and 32.
  • the toothed wheel 40 meshes with an inversion toothed wheel 41 pivoting on a shaft 42 around an axis dd ', while the wheel 41 meshes with a timer toothed wheel 23' pivoting on a shaft 43 around an axis ee '.
  • the wheel 23 ' is identical to the wheel 23, and therefore has the same diameter as the latter, and it comprises a pinion 25' similar to the pinion 25.
  • the shafts 42 and 43 are driven into housings of the bridge 7, the axes dd 'and ee' of these trees being oriented perpendicular to the main faces 8 and 9 of the movement.
  • a carriageway 18 ' identical to the carriageway 18, which comprises a pinion 19' similar to the pinion 19 and coming to mesh with the wheel 23 '.
  • the carriageway 18 ′ which supports the minute hand 4 ′ at its end, does not, however, exhibit pinching, which means that it pivots without constraint on the shaft 15, unlike the carriageway 18.
  • an hour wheel 26' identical to the wheel 26, which meshes with the pinion 25 ', and which comprises a barrel 27' supporting the hour hand 5 '.
  • the diameters of the mobiles 19 ', 23', 25 ', 26' and 40 ' are, in this case, equal respectively to the diameters of the mobiles 19, 23, 25, 26 and 36, it follows that the needles 4 ′ and 5 ′ rotate around the axis aa ′ at the same speed as the corresponding needles 4 and 5, but in the opposite direction to the latter thanks to the reversing wheel 41.
  • the diameters of the mobiles 19 ', 23', 25 ', 26', 36 and 40 could be different from those indicated, provided that their ratios are determined so as to ensure the speeds 4 'and 5' correct rotation.
  • the time setting of the first display comprising hands 4 and 5 is obtained, as has already been indicated, by means of a conventional time setting rod.
  • the independent time setting of the two displays is made by means of a control member 50 in the form of a rod secured to an external pusher not shown.
  • the rod has a conical end 51 which is arranged opposite the pinion 39 so as to remain outside the toothing of this pinion when the pusher is not activated.
  • the pusher being at rest, the second display can then be set to the time by moving the hands 4 'and 5', which also modifies, of course, the position of the hands 4 and 5.
  • the first display can then be set to the time by moving only hands 4 and 5.
  • the shaft 30 pivots during this operation, but its movement is not transmitted to the wheel 40 since the roadway 37 is blocked.
