Definitions

  • the subject of the present invention is a timepiece comprising a frame, a movement mounted on the frame for driving movable members for displaying the time in rotation about a first axis, and a trigger mechanism carried by said frame and operatively connected to said movement for bringing a first and second contact element into contact at a trigger time adjustable in advance; said trigger mechanism comprising: a first support rotated by said movement about a second axis distinct from said first axis said first contact element being disposed on said first support outside said second axis; and a second support adjustable in rotation around said second axis and comprising means for rotating said first support on said second support, said second contact element being disposed on said second support substantially at the same distance from said axis as said first contact element according to the preamble of claim 1.
  • the trigger mechanism comprises a rod passing through a hole in the case of the timepiece.
  • This rod comprises a first shoulder having a diameter greater than the diameter of this hole and resting on the housing.
  • a wheel driven by the movement of the timepiece and carrying the first contact element is freely mounted on this shoulder.
  • a disc carrying the second contact element is fixed to a second shoulder of the rod, a shoulder which has a diameter even greater than that of the first shoulder.
  • a washer is disposed between the wheel carrying the first contact element and the case of the timepiece to prevent direct contact between this wheel and this case.
  • a sleeve having a diameter greater than that of the hole made in the housing is slid over the rod and fixed to the latter by a radial screw.
  • the positioning of the trigger mechanism on the case of the timepiece is only ensured by parts having relatively small diameters, smaller in any case than the diameter of the circle traversed by the contact elements during the operation of the timepiece and / or the setting of the trigger time. This can result in unwanted displacements of the various components of the trigger mechanism with respect to the timepiece itself or with respect to each other, displacements which can disturb the operation of this mechanism and / or of the timepiece. watchmaking.
  • the object of the present invention is to provide a timepiece comprising a trigger mechanism which is assembled in the form of a modular inseparable element before it is mounted and which has means for positioning it very reliably in the timepiece. watchmaking.
  • the watch shown in FIGS. 1 to 3 is of the electro-mechanical type, the time indicators being constituted by ordinary hour 1 and minute 2 hands moving in front of a dial not shown.
  • the hands 1 and 2 are carried, the first, by the barrel 3a of the hour barrel wheel, designated by 3 and, the second by the carriageway, designated by 4.
  • the motor, electric mechanism has not been shown, being known per se. It may be constituted by a stepping motor controlled by a quartz resonator via an adequate division chain. Energy will be supplied by an electric battery.
  • the hour-barrel wheel 3 is engaged with a wake-up wheel 5, of steel, interposed, with axial clearance, between a toothed wheel 6, of electrically insulating material, rotatably mounted in the movement plate, designated by 7, and a metal wheel 8, coaxial with said insulating wheel 6.
  • the gear ratio between the hour barrel wheel 3 and the alarm wheel 5 is 1: 1; however, this ratio can advantageously be 1: 2, so that the alarm wheel makes one revolution per twenty-four hours, in the case of a twelve-hour watch whose hour wheel makes two revolutions per day.
  • the wheel 5 is earthed in particular by means of the wheel 3 with which it remains in contact.
  • the insulating wheel 6 carries an electrically conductive contact element 9, in the form of a bar, the axis of which is parallel to that of said wheel 6, and the distance from the center of which corresponds to the distance from the center of a boss 5a, directed towards the insulating wheel 6, which the wheel 5 presents.
  • the latter is freely engaged on a barrel 8a which the wheel 8 presents, barrel crossed by a journal 6a of the wheel 6.
  • the latter also has a lug 6b engaged in a notch of the barrel 8a so that the wheels 6 and 8 are angularly integral. They are kept assembled by a riveting 6c from the end of the pin 6a.
  • the wheel 6 carries on its face opposite to that facing the wheel 5, a thin metal washer 10, in the form of a crown which is fixed to said wheel 6 by means of two diametrically opposed studs 6d (FIGS. 2 and 3).
  • the washer 10 has a radial arm 10a, directed inwards and deviating obliquely from the general plane of said washer 10.
  • the arm 10a bears elastically on the end of a pin 11, which is coaxial with the wheel 6 , and which is carried by a printed circuit substrate 12 of the watch.
  • the pin 11 is in electrical contact with one of the conductive tracks, designated by 13, of said circuit substrate 12.
  • the elastic arm 10a of the crown 10, forming a spring urges the assembly formed by the wheel 6 and the wheel 8 against a bridge 14 of the watch movement frame.
  • the wheel 8 is provided with a crown 15 of anti-friction plastic material by means of which it bears on the bridge 14. The latter therefore undergoes a slight elastic deformation; it therefore constitutes a spring urging the mechanically unitary assembly formed by the wheels 6 and 8 against the plate 7.
  • the wheel 6 has on the side carrying the washer 10 a cylindrical part 6a engaged substantially without play in a circular opening of corresponding diameter 7a formed in the plate 7.
  • the cylindrical part 6a is followed by a part of larger diameter 6f which is toothed on its periphery and which serves as an axial stop cooperating with the plate 7.
  • the wheel 5 and the wheels 6 and 8 provided with the elements 6a, 8a and 10 constitute a sub-assembly or module 100.
  • the module 100 comprises a mechanically unitary assembly formed of the elements 6, 8, 6a and 8a, which is mounted rotatable around an axis 101 in the frame 7, 14 of the watch.
  • the axis 101 coincides with that of the wheels 5, 6 and 8.
  • the wheel 5 is rotatably mounted and with axial play on said unitary assembly 6, 8, 6a, 8a.
  • the module 100 When mounting the watch, the module 100 is first put in place with the 6th part housed in the opening 7a of the plate 7. Then the bridge 14 is fixed in the position shown in FIG. 1, position for which it urges the part 6f against the plate 7 and for which the arm 10a is elastically deformed.
  • the toothed part 6f of the wheel 6 is engaged with a control pinion 16, which can be actuated manually using a control mechanism known per se 102, which makes it possible to manually modify the angular position of said unitary assembly 6, 8, 6a, 8a.
  • the wheel 8 is, in turn, engaged with an additional barrel wheel 17, which is engaged on the barrel 3a of the barrel wheel 3.
  • the wheel 17 which is coaxial with the wheel 3 comprises a barrel 17a on which is mounted a so-called alarm clock hand 18, used for the analog display of the alarm time.
  • the insulating wheel 6 comprises, on its face facing the alarm wheel 5, an annular rib 6g coaxial with said wheel 6, and the distance from the center of which is greater than that of the element 9.
  • a circular clearance 19 is provided in said face of the wheel 6, and it is suitably sized so that the boss 5a of the wheel 5 does not come into contact with the wheel 6 for all the relative angular positions of the wheels 5 and 6 for which the boss 5a does not is not located opposite the element 9.
  • This clearance is connected, by two inclined planes not shown, with the flat end face 9a that the element 9 has on the side directed towards the wheel 5.
  • This end face 9a is set back from the free edge of the rib 6g, so that the wheel 5 does not come into contact with the element 9 when the latter is not opposite the boss 5a.
  • the shrinkage of the end face 9a relative to the free edge of the rib 6g is sufficiently low for the boss 5a to come into contact with said face 9a when these two elements 5a, 9a are opposite one of the other.
  • the contact element 9 is a permanent magnet of the bar type.
  • the contact element 9 is a simple metallic element made of copper.
  • a spring in the form of a non-planar washer 103 is interposed between - and bears, on the one hand, on the wheel 8 and, on the other hand, on the wheel 5.
  • the module 100 is juxtaposed and not superimposed, with the assembly formed by the wheels 3 and 7 and their barrels 3a and 7a.
  • the axis 101 is spaced from the axis of the wheels 3 and 7, which is the axis of rotation of the hands 1, 2 and 18.
  • the presence of the module 100 in the watch does not cause an increase in the thickness of the latter.
