Definitions

  • the present invention relates to a timepiece with a date display by means of two disks respectively bearing the signs forming the units and the tens.
  • the present invention is essentially to overcome these disadvantages and, more specifically, to allow a date display that is both large and homogeneous structure.
  • the signs carried by the upper disk are arranged on its lower face and that the signs carried by the lower disk are arranged on its upper face. These signs are thus in planes very close to each other and the light travels practically the same way, thanks to which their appearance is almost identical.
  • the axes of rotation of the disks are preferably separated by a distance substantially equal to r 1 + r 2 - 2e, r 1 and r 2 being the radii of the disks and e the width of the ring bearing the signs.
  • the transparent top disc is provided with an anti-reflective surface treatment.
  • the plate engaged with the disk gear of the units comprises thirty teeth and a space
  • the board engaged with the pinion of the tens disk has four teeth and twenty-seven spaces distributed according to the sequence: nine spaces - one tooth - nine spaces - one tooth - nine spaces - one tooth - one space, one tooth.
  • the timepiece represented in the drawing in this case a watch movement, comprises a plate 10 intended to serve as a support, in particular, a date mechanism.
  • the latter comprises two disks 14 and 16, of the same radius r , each carrying, on a peripheral ring of width e , a series of signs 14a and 16a allowing the display of the tens and the date units, respectively.
  • the tens disk 14 is slightly lower than the disk of the units 16 and carries, in a conventional manner the signs 14a, regularly distributed in the number of 8, which form twice the sequence 0 (or a white space), 1, 2 3. It may be, for example, metal, opaque plastic or other transparent material (plastic, glass or sapphire) coated with an opaque layer on its underside.
  • the disc of the units 16 carries, also in a conventional manner, the signs 16a, regularly distributed in the number of 10, which form the sequence of the digits from 0 to 9. It is necessarily made of transparent material, such as plastic, glass or sapphire. Advantageously, its upper face is coated with an anti-reflection layer 16c, which improves the readability of the display.
  • the lower disc 14 and the upper disc 16 pivot about axes parallel to each other on pins 18 and 20 ( Figure 3) which they are secured by means of screws 22 and 24.
  • the two disks 14 and 16 cooperate to present in juxtaposition the signs of their respective rings so as to provide an indication of the date. So that this juxtaposition is carried out correctly, it will be noted that the distance D separating the tenons 18 and 20 must be substantially equal to: two r - e .
  • the date is read through a dial 26 in which is practiced a window schematically shown in Figure 1 by a rectangle 28.
  • the signs 14a of the lower disk are disposed on its upper face but that the signs 16a of the upper disk are arranged on its underside.
  • the difference in levels between the signs 14a and 16a substantially corresponds to the space between the two disks, which is extremely small, typically from 0.1 to 0.2 mm.
  • the drive discs 14 and 16 is provided by means of two pinions 32 and 34 respectively mounted on their axes and under the discs. These gears each have as many teeth as the disk associated with it includes signs. This means that the pinion 32 of the tens disk 14 carries 8 teeth and the pinion 34 of the disk of the units 16 bears 10.
  • Two identical jumpers 36 and 38 respectively cooperate with the pinions 32 and 34 to position them. As will be described later, these jumpers are mounted adjustable in position to ensure optimal alignment of the signs carried by the two discs.
  • the pinions 32 and 34 mesh with a control wheel 40 pivotally mounted between them on the plate 10 to which it is fixed by means of a screw 42. It will be noted that the axes of these two gears (and therefore disks 14 and 16 ) and the axis of the control wheel 40 are aligned.
  • a detent 44 which will be described later in detail, serves to achieve instantaneous date training by acting on the control wheel 40. It is armed by a pin 46 mounted on a wheel of twenty-four 48 hours which makes one turn a day. This is connected to the clockwork in a conventional manner and not shown in the drawing.
  • the control wheel 40 is formed of two boards 50 and 52 superimposed respectively provided with a toothing 50a and 52a.
  • the toothing 50a of the upper board meshes with the pinion 32 associated with the lower disk of the tens 14, while the toothing 52a of the lower plate meshes with the pinion 34 associated with the upper disk of the units 16.
  • the two boards are positioned one relative to each other by means of pins 54.
  • the teeth 50a and 52a have the same module and the same pitch diameter but, as shown in Figure 2, they are incomplete. More precisely, the modulus of these teeth is equal to 1/31 th of their original diameter.
  • Each toothing should have thirty-one teeth but, as can be seen, the toothing 50a has thirty teeth and a space, while the toothing 52a has four teeth and twenty-seven spaces.
  • Such a configuration of the wheel 40 makes it possible to drive the discs 14 and 16 so that they respectively perform 1 half-turn and 3 turns per month, and successively display the numbers 1 to 31, then return to 1.
  • the four teeth and twenty-seven spaces of the lower plank 52 are distributed in the following sequence: nine spaces - a tooth - nine spaces - a tooth - nine spaces - a tooth - a space - a tooth.
  • the two boards are arranged so that the tooth placed after the isolated space of the board 52 meshes with the pinion 34 when the single space of the board 50 is opposite the pinion 32. This position corresponds to the passage of the 31 one month to the 1st of the following month.
  • the detent 44 provides the connection between the twenty-four hour wheel 48 and the control wheel 40. It is in the form of a U-shaped metal piece, with three elastic arms 44a, 44b and 44c. It is arranged in the thickness of the movement so as to cooperate on the one hand with the lower board 52 and on the other hand with the pin 46.
  • the arm 44a ensures the attachment of the detent 44 on the plate 10, by its free end formed of a board 44d pierced with holes 44e for the engagement of a pin and a screw not shown in the drawing.
  • a structure 44f for the correction of the date is substantially at the junction between the arms 44a and 44b.
  • the arm 44c has, at its free end, a jumper 44g provided with two bosses 44h and 44i engaged with the toothing 52a of the board 52 and, in its middle part, a drive structure formed of a withdrawal plane 44j and a 44k arming finger. This structure cooperates with the pin 46 of the twenty-four hour wheel 48.
  • Wheel 48 rotates counterclockwise. It is oriented so that at the end of the day, its pin 46 comes to bear against the withdrawal plan 44j. The force it generates then causes a deformation of the trigger 44 so that the jumper 44g away from the toothing 52a, until the bosses 44h and 44i are no longer in contact. This position is reached when the pin 46 completes scanning the withdrawal plane 44j and comes into contact with the finger 44k.
  • the rotational movement of the pin 46 brings the trigger 44 to the right, with a displacement substantially equal to one step of the wheel 40, then towards the latter until the bosses 44h and 44i enter again into the spaces in between the teeth of the board 52. In this position, the pin 46 can no longer cause the relaxation 44. It is released gradually finger 44k, finally releasing the trigger which then resumes its rest position as shown in drawing, moving to the left and advancing a wheel 40 which, in turn acts on the two gears 32 and 34.
  • the jumper 44g comprises the two bosses 44h and 44i, which are spaced from each other by a value equal to the pitch of the toothing 52a. There is, in this way, always at least two surfaces of the bosses which cooperate with the toothing 52a to ensure training on an angle corresponding to a step.
  • the correction of the date is done, in a conventional manner, by means of a time-setting rod (not shown in the drawing) which drives a wheel of correction 56 provided with four pins 58 cooperating with the structure 44f. More specifically, the latter is formed of a withdrawal plane 44l and a finger 44m.
  • the assembly formed by the pins 58 and the structure 44f works identically to the assembly defined by the pin 46, the plane 44j and the finger 44k.
  • the two jumpers 36 and 38 are mounted adjustable in position to ensure optimal alignment of the signs carried by the two discs.
  • they comprise a U-shaped body whose two branches, identified by the letters a and b , are extended by a fork c .
  • the branch form spring and engages with its free end, with the gear 32 or 34 to perform the function jumper.
  • Branch b is rigid. Its free end is provided with a cylindrical hole in which is engaged a screw 60, while its other end has an oblong hole provided with a hole, in which is engaged a screw 62.
  • the fork c cooperates with an eccentric 64.
  • the screws 60 and 62 and the eccentric 64 are fixed in the plate.
  • the tens disk 14 as shown, has two sets of signs 0, 1, 2, 3, which defines 8 positions. In this way, its diameter is substantially the same as that of the disk of the units 16, which has 10 distinct positions. Alternatively, it is also possible to provide a disk 14 having only one series of signs, or 4 distinct positions, so that it can be smaller diameter. In this case, the distance separating the axes of the two disks, of respective radii r 1 and r 2 , must be substantially equal to r 1 + r 2 - 2e.
  • the embodiment described advantageously comprises two disks pivoting about distinct axes, but it would also be possible to arrange them coaxially.
