Definitions

the present invention relates to the mechanisms for displaying the date and more particularly to mechanisms of this kind in which the date is displayed with two separate digits, each of which is inscribed on a coin distinct which allows for larger numbers and therefore better legibility of the date.
Such a mechanism is still known from document CH 689.601 in which the tens disk also pivots inside the disk of the units.
the disk of the units must obligatorily contain two teeth internals, one for its training by the watchmaking movement and the other for the training of the tens disk. These two teeth are necessarily offset in height so that here too the mechanism has a height important, which is always a disadvantage in timepieces, especially wristwatches.
the tens disk is registered inside the disk of the units, one is also limited in the positioning of the display window.
date display mechanisms of this type existing have two main disadvantages, their thickness and to a lesser extent measures the limitation imposed on the positioning of the date display window.
the present invention aims to achieve a date display with two separate digits, each carried by a different room which obviates the aforementioned drawbacks of the known mechanisms.
Another object of the present invention is to simplify in a very important the display mechanism, on the one hand by reducing the number of parts of it and secondly by making sure that these parts are easy to manufacture, especially do not require complicated machining or recovery.
the attached drawing illustrates schematically and by way of example a form execution of the date display mechanism according to the invention.
Figure 1 is a plan view of the mechanism in the display position from 29.
Figure 2 is a plan view of the mechanism during the change of dates from the 29th to the 30th.
Figure 3 is a plan view of the mechanism in the display position from 30.
the mechanism for displaying a large date illustrated in the drawing includes a disk of the units 1 constituted by a crown arranged in the movement as a conventional calendar crown and driven by the watch movement in a conventional way.
the first series has numbers increasing from 1 to 9
second and third series include numbers increasing from 0 to 9
the fourth series only includes the two numbers 0 and 1.
this unit disc has a total of 31 digits uniformly distributed on its periphery and arranged following each other. However here each digit has only one digit and so can be notoriously bigger.
Each of these figures comes successively as and when the rotation of the disk units 1 place themselves in a box of units 2 that includes the dial of the watch.
the thirty-one digits of a digit carried by the disk units are inclined relative to a radius of the disk, the value of this inclination that can vary from 0 ° to 90 ° and depends on the position of the counter display 2 units around the circumference formed by the disk of units. If Unit 2 is located six to twelve hours away from the dial, numbers carried by the disk of the units 1 are oriented radially with respect to this disc and the inclination is 0 °. If the unit counter 2 is located at three or nine hours of the dial, the numbers carried by the disk of the units 1 are oriented tangentially to the disk and the inclination is 90 °. For all intermediate position of the unit counter 2, the inclination of the figures carried by the disk of the units 1 will be between 0 and 90 ° with respect to a radius of this disk units 1. The positioning of the counter of units 2 can be done freely and without constraint.
This disk of the units 1 has an internal toothing 3 of thirty-one teeth cooperating with a finger 4 driven at a rate of one turn per day by the rotation of the hour wheel which carries the hour hand of the movement.
the disk of the units 1 is maintained in its angular position, for which a figure appears in the unit 2 counter, using a jumper 6 subjected to the action of a return spring 7.
finger 4 moves the disc units 1 step as, this is illustrated in Figures 2 and 3, and the next digit is then placed in the box of units 2.
a cam 8 controlled by the winding crown of the movement allows the user to make quick date changes through the rotation of said winding crown.
the teeth of the toothing 3 could be symmetrical as are the fingers of the cam 8, so the change Quick date can be done one way or the other. This is advantageous, especially when setting the time of the watch after a long downtime of it.
This mechanism also comprises a mobile of tens 9 formed of a square plate carrying, by decal or engraving, etc. the numbers 1, 2, 3, 0 or 1, 2, 3 and an empty space. These figures are each arranged in a corner of the plate and are each tangent to one of the four sides of the plate.
This mobile of tens 9 is placed just above the disk of the units 1 and is attached to a pinion with four teeth 10.
a jumper 11 subjected to the action of a return spring 12 maintains the angular position of the mobile tens between two actuations not by step of it.
Each digit carried by the mobile tens can appear in this box of tens 13 that includes the dial of the watch.
This window of tens 13 is located next to and to the left of the unit 2 counter.
Training step by step mobile tens of 9 is from the disc of units 1 by an external toothing thereof with four teeth 14 cooperating with the teeth of the pinion 10.
the four teeth 14 of the toothing disk drive units 1 are positioned to rotate the mobile tens of a quarter of a turn during the passages from 09 to 10; of 19 at 20; from the 29th to the 30th and from the 31st to the 01st of each month.
the thickness of the tens plate 9 can be very thin, for example 0.1 mm, and can be accommodated in a clearance made in the underside of the dial.
the mechanism large date according to the present invention therefore introduces no thickness additional to the basic movement unlike the big date devices known.
the mobile of tens 9 can be placed in the corners of the dial outside the movement.
the date display mechanism described can be used to display other indications than the date, to display any two-digit indication, by example the display of the hour or minutes, a counter display etc. he it is enough that the figures carried by the disk of the units 1 and the mobile of the tens 9 as well as their training correspond to the desired display.
a peculiarity of the described mechanism lies still in the elongated form teeth 14 of the peripheral toothing of the disk of the units.
This width of teeth 14 is such that it blocks any rotation of the pinion 10 as the teeth Internal 3 of the disk of the units 1 did not pass the point of the jumper 6 (see Figure 2). In this way, any discrepancy between the disk of the units 1 and the mobile of the tens 9 which could intervene especially during the manipulations of setting the hour of the hands in front or behind.
the parts of this display mechanism are easy to manufacture or machine, indeed the disk of the units 1 is of simple form, thanks to the fact that its teeth 3 and 14 are not superimposed but located one inside and the other outside, and can thus be obtained by stamping, manufacturing process simple, inexpensive and fast. The same goes for the mobile plate of tens 9.
this display mechanism combines the advantages of a great date, very thin, free positioning of the display windows, very simple by the reduced number of parts, ease of manufacture and a reduced cost.
