Description

Technical area

[0001] The present invention relates to a watch mechanism for a timepiece, in particular a watch mechanism allowing a particularly readable and/or dynamic display.

State of the art

[0002] Timepieces, and in particular wristwatches, most often indicate information (for example time information) with one or more indicator members, for example one or more hands. In general, these indicator members have a fixed end and a free end and rotate around an axis passing through their fixed end. The free end generally cooperates with a scale carrying indications, for example time indications. This free end points to these indications. In other cases, the timepiece does not have a scale and the wearer of the timepiece deduces the information associated with the indicator members on the basis of the angular position of the free end of one or more indicator organs.

[0003] Although very widespread, this reading is not very intuitive and requires learning for children or people accustomed to digital displays.

[0004] Timepieces with digital or alphanumeric displays allow for more intuitive reading. However, these timepieces are generally perceived as less qualitative and less aesthetic than timepieces with hands.

[0005] Document CH700615 describes a timepiece in which the hours are indicated by means of mobiles visible through the dial, all the mobiles being rotated in a first position with the exception of one mobile rotated in a second position . The timepiece includes a mechanism allowing the mobile which occupies the second position to be rotated each hour to return it to the first position, and to turn another mobile from the first position to the second position. In this timepiece, the current time is determined at each moment by the location of the mobile occupying the second position.

[0006] Despite the rotation of the mobile carrying the current time, the display remains static most of the time.

Brief summary of the invention

[0007] An aim of the present invention is to propose a watch mechanism free from the limitations of known watch mechanisms.

[0008] Another aim of the invention is to propose a watch mechanism allowing a particularly dynamic display.

[0009] Another aim of the invention is to propose a watch mechanism allowing a particularly readable display.

Another aim of the invention is to propose an alternative watch mechanism to known displays.

[0011] According to the invention, these goals are achieved in particular by means of the watch mechanism according to claim 1, preferential embodiments being given in the dependent claims.

[0012] The watch mechanism for a timepiece according to the invention comprises a cam arranged to be rotated around a cam axis, occupying (at least) a number of angular positions equal to one revolution divided by a whole number. In one embodiment, this number corresponds to the number of indicator members of the timepiece.

The watch mechanism for a timepiece according to the invention comprises a set of indicator members, each indicator member being arranged to rotate around an indicator member axis.

[0014] The watch mechanism for a timepiece according to the invention comprises a set of rockers, each rocker being associated with an indicator member and being placed in correspondence with one of these angular positions, and a leading mobile, arranged to rotate permanently around a leading mobile axis.

[0015] In the watch mechanism for a timepiece according to the invention: - when the cam is in one of its angular positions, it cooperates with a rocker, thus activating a clutch between the driving mobile and the indicator member of this rocker, consequently causing the rotation of this indicator member, this rotation making it possible to indicate information (temporal or non-temporal) to a user of the timepiece, and - when the cam leaves this angular position, the The clutch is deactivated, which stops the rotational drive of this indicator member.

[0016] In one embodiment, the cooperation between the cam and the rocker is made in correspondence with a hollow or a protuberance of the cam. In one embodiment, it is preferable for the cam to include a hollow rather than a protuberance, in order to reduce or even avoid the risk of breakage of the mechanism according to the invention.

[0017] The watch mechanism according to the invention allows a particularly dynamic display: the information intended for the user of the timepiece is indicated at each moment in correspondence with the indicator member which rotates around its axis at the moment where the user wishes to read this information and for the time associated with this information. For example, the indicator element associated with the “10 o'clock” time indication rotates for 60 minutes, namely from 10:00 a.m. to 11:00 a.m. and stops rotating when it is 11:00 a.m. At this moment, it is the indicator element associated with the “11 o'clock” time indication which begins to rotate until 12:00 p.m.

[0018] In other words, it is the rotation of the indicator member which allows the user to deduce information intended for the user. Indicator organs which do not rotate when the user wishes to read information do not allow this information to be deduced.

[0019] The watch mechanism according to the invention also allows a particularly readable display: the user quickly detects the indicator member which rotates on itself and deduces information therefrom.

[0028] In one embodiment, the watch mechanism comprises a transformation mobile, arranged to transform a continuous rotation movement into a jerky rotation movement, and to rotate jerkily around an axis of the mobile, thus occupying different angular positions, the cam being integral with this mobile.

[0029] In this context, the term "mobile" does not necessarily indicate the assembly of a wheel with a pinion, but generally indicates a "mobile" element (adjective), for example an element with a rotational movement .

[0030] In one embodiment, the transformation mobile is a Maltese cross, for example a Maltese cross with interior branches (or pointing towards the center of the watch mechanism).

[0031] In one embodiment, the cam has the same speed as the transformation mobile.

Example(s) of embodiment of the invention

[0049] In the following description provided by way of example, reference will be made, for simplicity, to a watch mechanism in which the cam is arranged to be rotated in a jerky manner. The invention, however, is not limited to such a watch mechanism but also relates to watch mechanisms in which the cam is arranged to be rotated in a dragging manner.

[0050] A first embodiment of the watch mechanism 100 according to the invention is visible in Figures 1 to 5.

[0051] In this embodiment, the watch mechanism 100 comprises a cam 20 arranged to be rotated around a cam axis A. Cam 20 occupies (at least) a number of angular positions equal to one revolution divided by an integer. In the embodiment of Figures 1 to 5, this integer corresponds to the number of indicator members 10 of the timepiece, twelve in the example illustrated.

[0052] In this embodiment, the cam 20 is arranged to be rotated jerkily and it forms part of a transformation mobile 70, which forms with it a single piece. In this embodiment, the cam 20 therefore has the same rotation speed as the transformation mobile 70.

The transformation mobile 70 is arranged to transform a continuous rotational movement into a jerky rotational movement, and to rotate jerkily around an axis of the mobile, thus occupying different angular positions. In the embodiment of Figures 1 to 5, the mobile axis corresponds to the axis of cam A.

[0054] In the embodiment of Figures 1 to 5, the transformation mobile 70 is a Maltese cross, for example a Maltese cross with interior branches (or pointing towards the center of the watch mechanism), which cooperates in a manner known with a finger 81 carried by a driving wheel 80 of the basic movement (for example the movement allowing seconds, minutes and/or hours to be counted) of the timepiece comprising the watch mechanism 100.

[0055] In other embodiments (not illustrated), the cam 20 is integral with this transformation mobile 70.

[0056] In other embodiments (not illustrated), the cam 20 does not necessarily have the same speed as the transformation mobile 70.

[0057] Each indicator member 10 is arranged to rotate around an axis B of the indicator member. In the embodiment of Figures 1 to 5, the axis B of the indicator member passes through the center of gravity of the indicator member concerned 10.

[0058] In the embodiment of Figures 1 to 5, the indicator members 10 are semi-bubbles or semi-spherical elements. The invention, however, is not limited to indicator members 10 having these shapes but also includes other indicator members 10 having another three-dimensional shape (for example bubbles, spherical elements, cubic elements, pyramidal elements, polyhedra, etc.) and also substantially two-dimensional elements such as for example disks, polygons, alphanumeric characters or symbols.

[0059] At least one indicator member 10 can carry one (or more) decorative pattern(s) 11, for example a relief pattern, as is visible in Figure 3, in order to further increase the dynamism and/or the readability of the information indicated when the indicator member 10 turns on itself.

The watch mechanism 100 also comprises a set of rockers 30, better visible in Figure 2, each rocker 30 being associated with an indicator member 10 and being placed in correspondence with one of the possible angular positions occupied by the cam 20.

[0061] As can be better seen in Figures 4 and 5, in the illustrated embodiment, each rocker 30 comprises a first part 301 and a second part 302 substantially parallel to the first part 301, the first part 301 being arranged to cooperate with the cam 20 and the second part 302 being arranged to carry the indicator member 10 associated with the rocker 30 (and possibly an intermediate gear 60 also, if present).

[0062] In the illustrated embodiment, the first part 301 and the second part 302 are two separate parts connected together by fixing means. In another embodiment (not illustrated), at least one flip-flop of the set of flip-flops (and preferably all the flip-flops of the set of flip-flops) is in one piece, namely made monolithic.

[0063] The watch mechanism 100 also comprises a driving mobile 40, arranged to rotate permanently around an axis of the driving mobile. In the embodiment of Figures 1 to 5, this driving mobile 40 is a ring which rotates around the same cam axis A. As can be seen in Figure 2, this driving mobile 40 comprises internal teeth 402 and external teeth 401, and the internal teeth 402 cooperates (directly or indirectly, for example via an intermediate wheel 51) with a wheel 50 of the movement base of the timepiece, which also rotates permanently around its axis (which in the example illustrated corresponds to cam axis A).

[0064] In the watch mechanism 100 for a timepiece according to the invention, when the cam 20 is in one of its angular positions, it cooperates with the rocker 30 which is also located in correspondence with this angular position, by activating thus a clutch between the driving mobile 40 and the indicator member 10 of this rocker 30, consequently causing the rotation of this indicator member 10, this rotation making it possible to indicate information (temporal or non-temporal) to a user of the timepiece.

[0065] In the embodiment of Figures 1 to 5, the cooperation between the cam 20 and the rocker 30 is carried out in correspondence with a recess 21 of the cam 20. In other embodiments, it is carried out in correspondence of a protuberance (not illustrated) of cam 20.

[0066] The watch mechanism 100 therefore allows a particularly dynamic display: the information is indicated to the user of the timepiece thanks to the rotation of the indicator member (or indicator members) 10 in correspondence of which(which ) the clutch is activated, the other indicator elements do not turn. In other words, the information is indicated at each moment in correspondence with the indicator member 10 which rotates at the moment when the user wishes to read this information. In other words still, the indicator members 10 which do not rotate (they are stationary) at the moment when the user wishes to read information do not make it possible to deduce this information.

[0067] The watch mechanism according to the invention also allows a particularly readable display: the user quickly detects the indicator member 10 which rotates on itself and deduces information therefrom.

When the cam 30 leaves this angular position, the clutch is deactivated, which stops the rotational drive of the indicator member 10 rotating on itself.

[0069] The clutch is one of several types of clutch mechanisms, including one of vertical clutch mechanisms, horizontal clutch mechanisms and swinging gear clutch mechanisms, known therein. -themselves in the field of technology, and which will not be described here.

[0070] By way of non-limiting example, the embodiment of Figures 1 to 5 uses a horizontal clutch between the external teeth 401 of the ring 40 is a toothing of a pinion 12 carried by the axis B of the indicator member 10, via an intermediate gear 60, as can be seen in Figure 4. Of course, the presence of the intermediate gear 60 is not essential, and the pinion 12 could mesh directly with the external teeth 401 of the ring 40. If an intermediate gear 60 is present, it is not necessarily limited to two wheels as in the example illustrated, but it may include one wheel only or a number of wheels other than two.

[0071] In one embodiment, at least one indicator member 10 is arranged to rotate in only one direction of rotation (namely, either clockwise or counterclockwise). In another embodiment, at least one indicator member 10 is arranged to be able to rotate in both directions of rotation, namely clockwise and at other times counterclockwise. In another embodiment, at least one indicator member 10 rotates in one direction of rotation and at least one other indicator member 10 rotates in both directions of rotation.

[0072] In the embodiment of Figures 1 to 5, each rotating indicator member 10 gives information on one hour of the current time. In another embodiment, the indicator members 10 can provide information on the current minutes and/or seconds. In this case, they will not necessarily be in number of sixty because of their bulk, but they can be in number of a divisor of sixty, for example in number of six.

[0073] In the embodiment of Figures 1 to 5, the indicator members are equidistant between two neighboring indicator members. In other embodiments, the distance between an indicator member 10 and the adjacent one can vary.

[0074] In the embodiment of Figures 1 to 5, the indicator members 10 are arranged substantially in a circle. In other embodiments, they are arranged in a semicircle, in an arc, or in another geometry.

[0075] In one embodiment, the indicator member 10 rotates with a rotation speed of between 1 and 30 seconds per revolution, for example between 5 and 20 seconds per revolution, in particular at 12 seconds per revolution. Of course, these ranges and these values should not be considered limiting: using possible intermediate wheels, reductions in the speed of a wheel of the basic movement can be carried out in a known manner, also giving d other values.

[0076] In one embodiment, the watch mechanism 100 comprises a brake 13 for each indicator member 10, arranged to brake the rotation of the corresponding indicator member 10 when the rotational drive of this indicator member is stopped. In one embodiment, this brake 13 also makes it possible to limit or even cancel unwanted movements of the associated indicator member 10 when the user moves the timepiece comprising the watch mechanism 100.

[0077] In one embodiment, the brake 13 comprises a tenon 131 connected to a whip 132, as can be seen for example in Figure 1.

[0078] In the embodiment of Figures 1 to 5, the watch mechanism 100 comprises a roller 320 associated with each rocker 30, visible for example in Figure 5. This roller 320 is used in a known manner to replace the sliding friction by the rolling friction during contact of a rocker 30 with the cam 20.

[0079] In the embodiment of Figures 1 to 5, the watch mechanism 100 comprises a return spring 91 (best visible in Figures 4 and 5) associated with each rocker 30, which improves the cooperation between the rocker 30 and the cam 20.

[0080] In the embodiment of Figures 1 to 5, the watch mechanism 100 also includes a stop 92 associated with each rocker 30, better visible in Figure 4, to limit pivoting of the corresponding rocker 30.

[0081] In the embodiment of Figures 1 to 5, the watch mechanism 100 comprises a one-piece part 90, clearly visible in Figure 2, comprising both rocker return springs 91 and stops 92. other embodiments, the one-piece part 90 comprises either the rocker return springs 91 or the stops 92. In other embodiments, neither the rocker return springs 91 nor the stops 92 belong to a one-piece part .

[0082] In the embodiment of Figures 1 to 5, the transformation mobile 70, the ring 40 and the one-piece part 90 are (at least partially) superimposed and the ring 40 is sandwiched between the one-piece part 90 and the transformation mobile 70, as is clearly visible in Figure 4.

[0083] In the embodiment of Figures 1 to 5, the axes B of all the indicator members 10 are perpendicular to a main plane xy (visible in Figure 1) of the driving mobile 40.

[0084] In the embodiment of Figures 1 to 5, the axes B of all the indicator members 10 are also perpendicular(s) to the corresponding rocker 30, in particular to at least one of the parts 301, 302 of each rocker 30.

[0085] The second embodiment illustrated in Figures 6 to 8 differs from that of Figures 1 to 5 at least in that the axes B' of all the indicator members 10 form an angle different from 90° relative to a main plane of the mobile leading xy and/or with respect to the corresponding rocker 30, in particular to at least one of the parts 301, 302 of each rocker 30.

To do this, the pinion 12 comprises teeth arranged to cooperate with the external teeth 401 of the ring 40 (via an intermediate gear 60 if necessary) taking into account this non-perpendicularity.

[0087] The second embodiment illustrated in Figures 9 to 11 differs from that of Figures 1 to 5 at least in that the mechanism comprises a second cam 20', arranged to cooperate with a first rocker or with a second rocker (not shown), thus activating a clutch between the driving mobile 40 and a first indicator member 10 or a second indicator member (not shown) associated with the second rocker 20', consequently causing the rotation of the first indicator member 10 (or of the second indicator member), this rotation making it possible to indicate a second piece of information (for example and without limitation, GMT information) to a user of the timepiece.

[0088] In one embodiment, the first cam 20 and the second cam 20' are at least partially stacked, as visible for example in Figure 11.

[0089] Although in the embodiment of Figures 9 to 11, the axis B of each indicator member 10 is perpendicular to the main plane xy of the driving mobile 40 and/or to the corresponding rocker 30, this characteristic must not be considered limiting: in fact, in this embodiment, this axis can be non-perpendicular to the main xy plane of the leading mobile 40 and/or to the corresponding rocker 30, as in the embodiment of Figures 6 to 8.

The watch mechanism 100 according to the invention can be used in a timepiece (such as for example a wristwatch) as an alternative or in addition to known displays.
