Description

Physical magnitude display on timepiece display base

Technical Field

The invention concerns a timepiece movement driving at least one output wheel set from a source of motion fixed to a plate or bridge in the movement, the source of motion being formed either by means of a device generating a time quantity value, or by means of a device detecting the magnitude of the state of a control of the movement, or by means of a device measuring or storing a physical quantity value external to the movement, the position of the output wheel set being associated, according to the nature of the source of motion, with the time quantity value, the state quantity value or the instantaneous value of the physical quantity value, respectively.

The invention also concerns a timepiece including at least one such timepiece movement.

The present invention relates to the field of timepieces, and more particularly to the field of watches, in particular mechanical watches.

Background

When a timepiece, in particular a wristwatch, has several complex functional elements, it is difficult to house these complex functional elements in the case and to take into account the visible surface of these complex functional elements, since most of them are connected to a visual display. In a position where several complex functional elements are juxtaposed, each dial would fill up more quickly, and it is therefore beneficial to utilize every available surface.

From swiss patent No.330897, Fabrique d' Horlogerie de Fontainemelon SA, a self-winding mechanism is known, in which an oscillating weight is made in the form of a frame and carries several winding wheel sets, but without any display function.

European patent No.2141558 by Les Artisans Horlogers S-arl discloses one such watch: the entire movement of the watch and the display carried by the movement are pivoted in the peripheral portion, thus forming an oscillating weight of the automatic winding mechanism. The purpose of this initial setting is to provide a definite stable position for the time display and to keep the surface of the balance in the reference plane by gravity, regardless of the spatial orientation of the watch case. In particular, this design does not allow the placement of an additional display in order to ensure the operation of the stem consisting of two parts, in particular because this display takes up space inside the watch case.

It is known from european patent No.1826633 to Blancpain SA to use the oscillating weight of a self-winding watch to carry a power storing display element. European patent application No.2360535A1 to Blancpain SA also discloses a device of this type in which hands and a dial for displaying power storage are mounted for synchronous rotation relative to an oscillating weight.

Swiss patent No.700222 by La Fabrique du Temps SA discloses a timepiece movement in which an oscillator and an escape wheel are mounted on an oscillating weight of a self-winding mechanism and drive an output wheel. In particular, the escape wheel is carried by a tourbillon carriage mounted on an oscillating weight and carrying a mechanical oscillator. In a "Cartier" manufactured according to this arrangement"in the tablet watch, the output wheel drives the hour and minute hand-motion mechanism, while the second hand remains integral with the spindle of the tourbillon support and rotates constantly with respect to the rotor.

Disclosure of Invention

In short, in a complex-function timepiece, in particular a wristwatch, it is desirable to utilize all the available space. In particular, with watches, some watches are provided with pivoting elements, in particular oscillating pendulums provided in self-winding watches, whose large front surface is generally not used or is rarely used as a display base.

The invention proposes to use as an additional display surface the front surface of these pivoting elements on the front face of a watch or on the back of a double-sided watch or for a display whose frequency of use is less than that of the front display.

More specifically, the invention proposes: the display of a quantity related to the time elapsed, in particular by extracting information from a small wheel or similar device; and/or status display, e.g., relative to the position of a button or selector; and/or a numerical display of a physical quantity external to the timepiece, measured by a sensor integrated in the timepiece or a sensor that transmits a value to a receiver integrated in the timepiece, which physical quantity may be, for example, a pressure value of air or water, a temperature, a magnetic field, radiation or similar value.

The invention therefore concerns a timepiece movement which drives at least one output wheel set from a source of motion fixed to a plate or bridge in the movement, the source of motion being formed either by means of a device which generates a time quantity value or by means of a device which detects the magnitude of the state of a control of the movement or by means of a device which measures or stores a physical quantity external to the movement, the position of the output wheel set being associated, according to the nature of the source of motion, with the time quantity value, the state quantity value or an instantaneous value of the physical quantity, respectively, characterized in that the instantaneous value is displayed on a display base which rotates with respect to the source of motion and comprises at least one display wheel set cooperating with the output wheel set, the display wheel set being permanently coupled with the output wheel set directly or through a gear train; in addition, the display base carries at least one auxiliary wheel set that pivots synchronously or at an integer pivot rate ratio relative to the display wheel set.

According to one feature of the invention, the timepiece movement includes at least one second output wheel set arranged to occupy a position associated with an instantaneous value of another physical quantity, or to define an overall range or extent of variation of the quantity of values that prescribe the quantity of the position of the first output wheel set.

According to one feature of the invention, the display base includes a plurality of display wheel sets that are either each mated with a single auxiliary display wheel set or each mated with a particular auxiliary display wheel set.

Detailed Description

The present invention relates to the field of timepieces, and more particularly to watches, in particular mechanical watches.

As shown in the figures, the invention relates to a timepiece movement 1. The movement 1 drives at least one output wheel set 3 from a motion source 2 which is fixed to a plate or bridge 6 in the movement 1.

The motion source 2:

or by means of a device 2A generating a time quantity;

or by means 2B of detecting the magnitude of the state of the control of the movement;

or by means 2C for measuring or storing physical quantities outside the movement.

The position of this output wheel set 3 is associated with the instantaneous value of the time, state or physical quantity, respectively, depending on the nature of the motion source 2.

According to the invention, the instantaneous value of the quantity is displayed on the display base 10. The display base 10 for displaying the value of this magnitude is mounted so as to rotate about the main pivot axis DP with respect to the plate or bridge 6 of the movement 1. Display base 10 includes at least one display wheel set 4 cooperating with output wheel set 3, display wheel set 4 being permanently coupled to output wheel set 3, either directly or through a gear train.

According to the invention, display base 10 also carries at least one auxiliary wheel set 5 which pivots synchronously or at an integral pivot rate ratio with respect to display wheel set 4.

Preferably, but not limitatively, display base 10 comprises means of kinematic connection to oscillating weight 7 of the self-winding mechanism, or, as shown in the figures, forming an oscillating weight of the self-winding mechanism. This kinematic connection can be formed by a permanently coupled direct drive, which is preferred in the present application, or by a non-couplable drive (which makes use of friction in particular), as the case may be.

In various embodiments, as shown in fig. 2-7, 9 and 11, display base 10 includes a plurality of display wheel sets that either all cooperate with a single auxiliary display wheel set 5, as shown in fig. 3, or each cooperate with a particular auxiliary display wheel set, as shown in fig. 2, 6 and 9.

For example, fig. 2 shows a movement 1 comprising three different types 2A, 2B, 2C of motion sources 2, each driving an output wheel set 3A, 3B, 3C, respectively, which drive a display device and an auxiliary display device 4A/5A, 4B/5B, 4C/5C, respectively, as described above.

Fig. 1 shows the case of a movement 1 with a single output wheel set 3. Here, the display base 10 is formed by a self-winding oscillating weight 7, which in turn comprises a weight body 23 and a weight bridge 22, which together define a chamber arranged to house the gear train.

The cannon pinion 17 is firmly fixed to the plate or bridge 6 of the movement 1 and carries a peripheral toothing 17A, which peripheral toothing 17A serves as an angular pivoting reference of the oscillating weight 7 about the main pivoting axis DP. This minute wheel 17 acts as a pivoting guide for the arbour 16, this arbour 16 being mounted integrally with the oscillating weight 7 and carrying a peripheral toothing 16A for transmitting the kinetic energy to a barrel ratchet (not shown here). The pivot guide may in particular be formed by a ball bearing or the like. The cannon pinion 17 also acts as a pivoting guide for the input wheel 11, which is arranged in permanent engagement with the output wheel set 3. The engagement shown is direct engagement, but it is possible to include an intermediate wheel set without departing from the invention, provided that input wheel 11 is still driven directly or indirectly by output wheel set 3. The guidance of the input wheel set 11 is also advantageously achieved by means of ball bearings.

Oscillating weight 7 carries display wheel set 4, display wheel set 4 being arranged to pivot about a first secondary pivot axis DS1 carried by display base 10. According to the invention, display wheel set 4 is permanently coupled, directly or indirectly, to first output wheel set 3. In fig. 1, which shows in particular the lunar phase display, the display wheel set 4 comprises a lunar phase disk 13 fixed to a wheel 12, this wheel 12 being connected with the input wheel 11 via an intermediate gear train 14 pivoting about an intermediate axis D1. The at least one auxiliary display wheel set 5 is arranged to pivot about a second secondary pivot axis DS2 also carried by the display base 10, which second secondary pivot axis DS2 is parallel to or merges with the first secondary pivot axis DS 1. In fig. 1, DS1 and DS2 merge and form a single secondary pivot axis DS, and the auxiliary display wheel set includes a moon cover 20 fixed on an arbour 19, the arbour 19 carrying a wheel 18, the wheel 18 meshing with an intermediate gear train 21. Advantageously, the spindle 19 is guided by the wheel 12. The intermediate gear train 21 meshes with the toothing 17A of the cannon pinion 17 and the transmission ratios in both the transmission chain of the display wheel set 4 and the transmission chain of the auxiliary display wheel set 5 are chosen as: so that pivoting of moon disk 20 occurs through the pivoting of oscillating weight 7 with a reverse motion compensation, and so that pivoting of moon disk 13 with respect to moon disk 20 appears to the user as if both moon disk and moon disk are fixed with respect to plate or bridge 6. Fig. 6 shows a front view of the lunar phase display function, in which the display device 4B is a lunar phase plate, the auxiliary display device 5B is a lunar cover, and they are pivoted together about the secondary axis DSB.

In the particular embodiment shown in fig. 2, 3 or 11, movement 1 comprises at least one second output wheel set arranged to occupy a position associated with an instantaneous value of another physical quantity, or to define the entire range or extent of variation of the value of this quantity, which defines the position of first output wheel set 3.

Fig. 3 thus shows the display base 10 in an embodiment with three output wheel sets 3X, 3Y, 3Z connected to the motion source formed by the driving means and the oscillator, these three output wheel sets each integral with the hand corresponding to the centre display of seconds, minutes, hours around the main pivot axis DAP, respectively. The display base 10 includes: an output display 13X, 13Y, 13Z for each input device, respectively, here also formed by a pointer; a single auxiliary output display 5 for the three output displays, coaxial with the three output displays and here formed by a dial 20. In a similar manner to fig. 1, the output displays 13X, 13Y, 13Z are each integral with a wheel 12X, 12Y, 12Z, the wheel 12X, 12Y, 12Z being in mesh with an intermediate gear train 14X, 14Y, 14Z, the intermediate gear train 14X, 14Y, 14Z in turn being in mesh with an output wheel 11X, 11Y, 11Z cooperating with the three output devices 3X, 3Y, 3Z. A dial 20 forming an auxiliary display common to the various displays is fixed to a wheel 18, this wheel 18 being connected via an intermediate gear train 21 to a toothed ring 17A, this toothed ring 17A providing the angular position of an oscillating weight 7, which in the present embodiment forms the bearing structure of the display base 10, so as to keep the axis of the dial 20 parallel to the axis of the dial of the main set of pointers, as shown in fig. 1, so that the dial is permanently maintained in the same angular orientation with respect to the plate or bridge 6 of the movement 1 and with respect to the case of the timepiece 100 containing this movement, except for the position of a secondary pivot axis DS defining a circle about the pivot axis DP.

Fig. 4 shows a watch 100 comprising the display base 10 of fig. 3, wherein a secondary display formed on the oscillating weight 7 replicates the central main display on the watch 100.

The variant shown in fig. 5 has a secondary display which is a time zone display and displays the time of a different time zone than the main display. In this embodiment, two additional holes 28, 29 in oscillating weight 7 display the sign and the value of the time difference between the second time zone displayed on oscillating weight 7 and the first time zone of the central display. Of course, for countries with half-hour time differences, such as India, Iran, Afghanistan or Iran, or for countries with quarter-hour time differences, such as Nepal, such time zone displays may be applied to the minute hand 13Y as well as the hour hand 13X.

As shown in fig. 10, a watch 100 having a first secondary display formed on an oscillating weight 7 is used to display the rate of deviation calculated by the time equation of the timepiece by means of hands 49 facing a dial 50, both the dial 50 and hands 49 being pivotable.

Fig. 11 shows, for illustrative purposes only, movement 1 with a pivoting display base 10 in one embodiment, wherein the movement includes two output wheel sets 3D and 3U for controlling the display of tens and units values of the date. The display base 10 has two input devices 11D and 11U, and includes: an output display for each of the input devices, the output display being formed by a tens wheel 34 and a units crown 33, respectively, the tens wheel 34 and the units crown 33 being pivotal about a second secondary pivot axis DS2 and a first secondary pivot axis DS1, respectively; and a single secondary output display 30 for both output displays, the secondary output display 30 carrying both output displays and a cover 31 comprising a reading aperture 32 revealing only the current date. Planetary carrier 30 includes a ring gear 30A meshing with intermediate gear train 21, intermediate gear train 21 meshing with ring gear 17A, and ring gear 17A representing the angular position of oscillating weight 7 forming display base 10.

Many variations are conceivable. Without limitation, the means 2A for generating a time quantity can therefore be constituted by: a device for generating a date, a device for generating a time display, a device for generating a lunar phase indicator, a device for generating a time equation of operation, a device for generating a time zone, or a device for measuring a time.

The means 2B of detecting the state of the timepiece control can be associated with the detection of the position of a button, or a selector, or an on/off switch, a zero reset indication, an activated time zone indication, or with the detection of a timed event from several events timed at the same time in the timepiece movement.

In applications particularly suited for displaying on a display base (e.g., an oscillating weight), it is also possible to employ, without limitation:

-a time equation as shown in figure 10;

-display of non-leap and leap years;

-display of a week calendar;

-display of morning/afternoon;

-day/night display.

These applications utilize coaxial secondary axes.

Other applications may utilize a secondary axis that is not coaxial:

not all-around displays, for example resulting from the movement of a toothed shaft in combination with a straight or curved rack portion.

Display resulting from the overlap of at least partially superimposed discs (for example, polarized discs), so that at some relative angular positions the superimposed areas are bright and at other angular positions the superimposed areas are dark. This type of display is particularly suitable for a stop/start state display, and, since no reference member oriented with respect to the plate or the case of the movement is required, it is not necessary to install a gear train for correcting the angular position of the display base with respect to the plate or the case.
