Definitions

  • the invention relates to a skeleton watch showing all or part of the organs of which it is made.
  • the watch of the invention and according to a first embodiment comprises in combination: - a middle part carrying a top glass and a back, - a frame adjoining the middle part and arranged in the space circumscribed by the middle part between the upper glass and the back, a leg adjoining the frame and extending towards the center of rotation of the display means presented by the watch, said leg covering at least said center, - a motor fixed to the frame and comprising a rotor directly driving a minute wheel bearing a minute mark, a fixed pinion driven into an orifice made in the leg at the location of the center of rotation of the display means, a shaft secured to the fixed pinion, a shaft around which the minute wheel and the hour wheel bearing the hour mark, the minute wheel bearing, offset, offset from its center are first and second coaxial planet gears, the first is engaged with the fixed pinion and the second with the hour wheel, - metallized pads and conductors on the inner face of the case respectively intended to receive the electrical and electronic components necessary for the operation of the watch and
  • the watch comprises in combination: - a middle part carrying a top glass and a back, a leg adjoining the middle and extending in the direction of the center of rotation of the display means presented by the watch, said leg covering at least said center and emerging in the space circumscribed by the middle between the upper glass and the background, - a motor fixed to the middle part and comprising a rotor directly driving a minute wheel bearing a minute mark, a fixed pinion driven into an orifice made in the leg at the location of the center of rotation of the display means, - a shaft secured to the fixed pinion, a shaft around which the minutes wheel and the hours wheel bearing are pivotally mounted an hour mark, the minutes wheel carrying, offset from its center, the first and second coaxial planet gears, the first of which is engaged with the fixed pinion and the second with the hour wheel, - metallized pads and conductors on the inner face of the case respectively intended to receive the electrical and electronic components necessary for the operation of the watch and to connect said components together, and
  • the watch presented in FIG. 1 shows a middle part 1 equipped with horns 2 intended to receive a bracelet.
  • the middle part here has a rectangular shape, but could also be round or of another shape.
  • the middle part is shown alone in FIGS. 2 and 3. It has housings 3 and 4, housings intended respectively to receive an upper glass 25 and a bottom 26, as seen in FIG. 6.
  • the middle part also has a housing 5 intended for receive a frame 6 shown alone in Figure 4 and disposed in the space 7 circumscribed by the middle part between the glass and the bottom.
  • the frame 6 is held on the middle part 1 by the bottom 26, itself fixed to the middle part in the housing 4 by gluing or by driving into a seal (not shown).
  • a leg 8 is attached to the frame 6.
  • This leg extends in the direction of the center of rotation 9 of the display means presented by the watch and covers at least this center.
  • the leg is a bridge connecting two opposite edges of the frame and is made in one piece with the frame.
  • the frame thus presented in a way forms the plate of the watch on which are mounted in any case the mechanical organs, such as the display means and the electric motor.
  • FIG. 1 illustrates the way in which the watch is organized.
  • a stepping motor illustrated by its core 10, its coil 11, its stator 12 and the axis 13 of its rotor.
  • This motor forms a unit in itself, its rotor pivoting in bearings fixed to its stator, as can be seen for example in the document CH-A-639 525 (US-A -4,483,627).
  • This procedure avoids providing bearings which would be part of the frame or bridges fixed on this frame which would weigh down the construction and would not go in the direction of the desired counting.
  • Attached to the motor rotor there are two fingers 14 which directly drive a large minute wheel 15 by its peripheral toothing 16.
  • the minute wheel is advantageously a transparent disc bearing a minute mark 17. It is therefore used directly as a means of 'minutes display.
  • the minute wheel carries 180 teeth and three pulses per minute supply the motor.
  • the hours are displayed by an hour hand 18 coupled to the minute disc 15 by a gear train whose operation is shown in section in Figure 6 and which will be explained now.
  • a fixed pinion 19 is driven into an orifice 20 formed in the leg 8 at the location of the center of rotation of the display means (see also Figure 4).
  • a shaft 21 is mounted integral with the fixed pinion 19 or is made in one piece with said pinion.
  • the minute wheel 15 carries, offset relative to its center, the first 23 and second 24 coaxial planet gears, the first of which is engaged with the fixed pinion 19 and the second with the hour wheel 22.
  • Such an arrangement has the advantage of great simplicity at the same time as an extremely small footprint and contributes greatly to the so-called mysterious aspect of the operation of the watch according to the invention.
  • This arrangement is known per se from document CH-A-615 066 (US-A-4 182 114) and the reader will refer to it if more details are desired.
  • FIG. 6 also shows that the length of the shaft 21 is chosen so that it forms a spacer between the underside of the glass 25 and the internal face of the bottom 26.
  • This arrangement maintains a constant distance between the glass and the bottom. Thanks to this arrangement, the ice and the bottom are prevented from bending, which could cause one or other of these elements to break when they are subjected to external pressures. This arrangement also allows the mobiles located between the glass and the bottom to move freely.
  • the pad 28 is intended to receive the negative electrode of a battery 38 which is connected to an integrated circuit 40 (under which the pad 32 is located) via the conductor 36.
  • a contact pad 41 is received by the track 29 which is connected to the integrated circuit 40 by the conductor 37.
  • a quartz 39 is received by track 30, affixed here for aesthetic reasons. The terminals of the quartz are soldered to the conductors 34 which connect the quartz to the integrated circuit 40.
  • the track 31 is used to connect, via the frame, the conductor 35 and a contact tab 42, the positive electrode of the battery 38 to the integrated circuit 40.
  • the pads 27, connected to the said integrated circuit by the conductors 33 are intended to come into contact with a plug 43 passing through the frame 6, plug on which the outputs 44 of the coil 11 of the motor are welded step by step.
  • the wiring device which has just been described takes up in part the invention expressed in the document CH-A-636,744 (US-A-4,475,822) and makes it possible to make the wiring necessary for the operation of the watch less visible.
  • the watch according to the invention is provided with a time-setting device implementing a crown-stem 50 which can assume a depressed rest position (that shown in FIG. 1) or a pulled working position.
  • the rod carries an annular housing 51 at one of its ends.
  • This housing cooperates, on the one hand, with a jumper 52 defining the two positions mentioned above and, on the other hand, surmounting the jumper, a contact blade 53.
  • the jumper 52 is fixed to the frame by means of the screw 54 and positioned by means of pins 55 and 56.
  • the contact blade 53 is also fixed to the frame by means of the screw 54 and positioned by means of the pin 55 and a bearing screw 57 under the head of which this blade can move.
  • the integrated circuit 40 can be provided with the same functions as those described in document CH-A-617,059 (US-A-4,185,453). In this case, if the rod is placed in the pulled position for less than a determined period of time (for example 4 seconds), the minute disc is advanced by one single step and if has this rod in the pulled position for a period longer than said period of time, the minute disc is advanced by 60 steps of one minute.
  • a determined period of time for example 4 seconds
  • the means for fixing and positioning the jumper and the contact blade are situated substantially in a plane perpendicular to the axis of the crown stem, so that they do not encroach not in the space circumscribed by the frame and this in the constant concern, presented by the present invention, to propose a skeleton watch as stripped as possible and revealing a maximum of empty space of elements.
  • the back 26 of the watch can be made of metal or colored plastic. It is however possible to use a transparent material, for example a sapphire crystal. In this case, the skeleton watch could also be called a transparent watch.
  • the minute wheel 15 is preferably made of transparent material, toothed on its periphery, which clearly shows the skeleton nature of the watch.
  • a metallic spoke wheel the planet gears being pivotally mounted on one of the spokes.
  • the frame 6 carries a small bridge 62 at the end of which is a guide stud 63.
