Description

Technical Field

[0001] The present invention relates to a device for displaying time information, particularly a method for operating a date display device. The present invention also relates to a device for displaying time information. The present invention further relates to a timepiece movement including the display device. Finally, the present invention relates to a timepiece, particularly a wristwatch, including the device or the movement. The present invention particularly relates to a display device or mechanism for date display of the "big date" type, i.e., using two disks, particularly a first disk indicating the units digit of the date and a second disk indicating the tens digit of the date.

Background Art

[0002] Patent Document 1 discloses a "big date" type date including two display disks juxtaposed in the same plane. The peripheries of the disks are circular, and as a result, both concave gaps occur between the disks at the openings.

[0003] Patent Document 2 discloses a solution for obtaining a big date type date having a linear separation between the display of the tens digit and the units digit of the date. The solution requires two display disks superimposed on two separate planes, thus requiring additional thickness and generating an obstructive height difference between the two digits.

[0004] In Patent Document 3, the "big date" type date display includes two display disks truncated over approximately 60°, where the first disk has numbers from 4 to 18 and the second has numbers from 19 to 31 and from 1 to 3. The disks are designed to be juxtaposed and, due to the truncated notch, are rotated in the opposite direction without getting caught. Each disk is designed to be alternately visible through a single opening. This solution requires a large display disk and / or a small font compared to a solution that utilizes two juxtaposed disks each provided with a display of the tens digit and the units digit.

[0005] A "big date" type date display typically utilizes two juxtaposed discs, displayed through an opening that is generally divided into two parts. Typically, the first part displays the tens digit and the second part displays the units digit. The opening needs to be separated to conceal the gap or unsightly gap between the two discs, which are shaped like double concave lenses. This gap is due to the circular shape around the display discs, allowing both discs to rotate without interference. [Prior art documents] [Patent Documents]

DETAILED DESCRIPTION OF THE INVENTION

[0017] An embodiment of the clock 300 according to the present invention will be described below with reference to FIGS. 1 to 5. The clock is, for example, a small clock, particularly a wristwatch. The clock includes an embodiment of the clock movement 200 according to the present invention. The clock movement includes an embodiment of the device 100 for displaying clock information. The clock movement 200 is - a mechanical movement, particularly an automatic movement, or - an electronic movement, or - a hybrid movement, and may be any of these.

[0018] The clock 300 also includes a case intended to receive the clock movement 200 and protect it from the external environment.

[0019] Preferably, the display device 100 is capable of displaying "big date" type information display, in which time information or time-related information, particularly information, is displayed by first and second disks provided to display the tens and units of the information, respectively.

[0020] The display device 100 includes a frame 90. The frame 90 may include a movement plate and / or a receptacle. The display device 100 may consist of a module that is assemblable and whose assembly is maintained independently of the remainder of the movement. When completed, the module may be fixed to the remainder of the clock movement 200, particularly to a blank of the remainder of the clock movement 200 such as a main plate. The frame 90 may be the frame of the clock movement 200.

[0021] The display device 100 that displays clock information, a) A first disk 11 that displays first clock information and a first end portion 11b provided therein b) Mounted to rotate around the first axle A1, First indicator gear 10, A second part 21b is provided, which has a structure that partially complements the structure of the first part, and the second end is provided, During at least a specific display jump, or during at least one display jump, i) Starting from the stationary position of axis A1, displace the first axis A1 such that the first indicator gear 10 is displaced relative to the second end in order to separate the first part 11b from the second part 21b. ii) Change the display, iii) Displace the first shaft A1 so as to move the first part 11b closer to the second part 21b, thereby displacing the first indicator gear 10 relative to the second end. Actuators 30, 40, 50, 52 are arranged in such a manner, Includes.

[0022] Advantageously, the display device further includes a second display gear 20, which includes a second disk 21. The second disk 21 has second clock information and a second end on which a second portion 21b is provided. The second display gear 20 is mounted to pivot around a second axis A2.

[0023] The operating means 30, 40, 50, 52 are activated during at least one display jump or during at least a specific display jump. - Rotate the second indicator gear 20 around the second axis A2, and / or - Rotate the first indicator gear 10 around the first axis A1. It is positioned to change the display accordingly.

[0024] In the embodiment described and illustrated in detail, the display device is a "big date" type date display device.

[0025] The first indicator gear 10 further includes a first pinion 12 fixed to the first disk 11. The first disk 11 includes a digit 11a intended to indicate the tens digit of the date, in particular a series of digits 0, 1, 2, 3, or a series of digits 1, 2, 3 (in the latter case, a blank space or absence of marking on the disk is used instead of the digit 0).

[0026] The second indicator gear 20 includes a second pinion 22 fixed to the second disk 21. The second disk 21 contains a digit 21a intended to indicate the units digit of a date, i.e., a list of digits from 0 to 9.

[0027] The first disk 11 may contain at least once a sequence of four digits 11a in the tens place, either from 0 to 3 or from 1 to 3. The second disk 21 may contain at least once a sequence of ten digits 21a in the units place, either from 0 to 9.

[0028] Preferably, the first and second discs 11 and 21 are in the same plane. More preferably, the first and second discs 11 and 21 are arranged side by side to position first information, such as the tens digit 11a on the first disc 11, and second information, such as the units digit 21a on the second disc 21, adjacent to each other, in order to display clock information such as the date. The information is displayed, for example, through an opening 201 in the dial; that is, the information appears within the opening formed by the opening.

[0029] The first and second axes A1 and A2 are preferably parallel.

[0030] Preferably, the two indicator gears 10, 20 are indexed by first and second jumpers 13, 23 which cooperate with first and second pinions 12, 22, respectively.

[0031] Preferably, the operating means is - Control gear 30, - Drive gear 40, - First movable support part 52, - An indexing element 50, such as a jumper 50, which is used to index the control gear 30, Includes.

[0032] The first and second indicator gears 10 and 20 are driven by the control gear 30. The control gear 30 is - A set of first teeth 31 that drives the first indicator gear 10, - A second set of teeth 32 that drives the second indicator gear 20, - A third set of teeth 33 that drives the control gear 30, The first and second sets of teeth 31 and 32 are intended to cooperate with the first and second pinions 12 and 22 of the indicator gears 10 and 20, respectively.

[0033] Each of these sets of teeth 31, 32 includes a truncated tooth or teeth of different dimensions, arranged to allow the first disc 11 and the second disc 21 to be driven in a predetermined order.

[0034] In this case, in the embodiment described, - The first set of teeth 31 includes four teeth that can cooperate with the first pinion 12, and - The second set of teeth 32 includes 30 teeth that can cooperate with the second pinion 22. The second set of teeth 32 is positioned coplanar or at the same height as the first set of teeth 31. Certain teeth of the second set of teeth 32 coincide with or inscribe in the first set of teeth 31, which contains teeth of a larger dimension than those of the second set of teeth, with a larger pitch circle diameter than that of the second set of teeth.

[0035] The third set of teeth 33 enables the control gear 30 to be driven using a pawl 41 positioned within the drive gear 40. Preferably, the drive is instantaneous or substantially instantaneous and is performed every 24 hours. In other words, the rotation period of the drive gear is 24 hours in order to enable the control gear 30 to be driven by at least one step per day using the pawl 41. In the embodiment described, the third set of teeth 33 includes 31 teeth positioned on the same plane as or at the same height as the first and second sets of teeth.

[0036] More generally, it should be emphasized that at least two of the sets of three teeth 31, 32, and 33 of the control gear 30 can be perfectly or partially matched.

[0037] The control gear 30 and the drive gear 40 pivot within the frame 90 around axes A3 and A4, respectively, which are preferably parallel to axes A1 and A2. Preferably, the control gear 30 is indexed or substantially indexed by an indexing element 50 (hereinafter referred to as a "jumper") which cooperates with a set of third teeth 33. The jumper 50 also pivots within the frame 90 around axis A5, which is preferably parallel to axes A1 and A2.

[0038] A particular feature of the solution according to the present invention is that, in the opening 201, the space or gap between the outer ends of the discs 11 and 21 does not have a gap in the shape of both concave lenses, but rather has a gap j1 of a constant width l1, as shown in Figure 2. Preferably, the width of the gap is zero. For this reason, advantageously, the opening 201 does not have to have a partition separating the tens digit and the ones digit display.

[0039] Therefore, the outer edge or perimeter of the first disk 11 adjacent to each tens digit 11a includes a portion 11b such that it closely follows the shape of a complementary portion 21b on the outer edge or perimeter of the second disk 21 adjacent to each units digit 21a, or vice versa. In other words, the shapes selected for the perimeters of the two disks 11, 21 are designed to have portions 11b, 21b of shapes that complement or closely follow each other, particularly at the opening 201. One or both disks 11, 21 may, advantageously, not have a circular perimeter or edges.

[0040] In this case, the outer edges or periphery of the disks 11, 21 in the embodiments described and illustrated include linear portions 11b, 21b adjacent to each of the information 11a, 21a. The linear portions 11b, 21b are preferably oriented radially perpendicular to axes A1, A2, as shown in Figure 2. This creates a gap j1 between each linear portion 11b, 21b with a constant, preferably zero, width l1 when both are positioned toward the opening 201. More specifically, the gap j1 has a linear or substantially linear shape with a constant or zero width.

[0041] Because the gap j1 has a width that is zero, substantially zero, or tends toward zero, the two disks 11, 21 are advantageously radially weighted or substantially weighted toward each other. For this reason, at least one of the two indicator gears 10, 20, in this case the first 10, is advantageously pivoted on a first movable support 52 (particularly a lever 52), and the first movable support 52 itself is pivoted within the frame 90 around an axis A51 different from the first axis A1. Axis A51 is, for example, parallel to (and away from) axis A1 and perpendicular to disks 10 and 11. The second indicator gear 20 is pivoted within the frame 90, for example. In other words, axis A2 is fixed relative to the frame. The lever 52 is intended to allow the first indicator gear 10 to be displaced, in particular in a plane P perpendicular to axis A1, during at least one driving stage of the control gear 30. This displacement is essential during at least one drive stage to rotate one and / or the other of the two disks 11, 21. This is because, due to the non-circular edges or periphery of the two disks, which are positioned with a small gap between them, the rotation would inevitably cause interference unless the intercenter space d1 between the two indicator gears 10, 20 is increased.

[0042] The first jumper 13 is preferably located within the lever 52. The second jumper 23 is preferably located within the frame 90.

[0043] The lever 52 cooperates directly or indirectly with a third set of teeth 33 of the control gear 30 so as to be moved during each stage of the indicator's drive. In other words, in each step, or with each tooth passed, the set of teeth 33 displaces the lever 52 in a back-and-forth motion. This kinematics will be described in more detail below. In the embodiment described and illustrated, the lever 52 is driven by a third jumper 50 which acts on the lever 52 using a part 50a that cooperates with a complementary part 52a formed on the lever 52 as shown in Figure 1. More specifically, the part 50a is a pin or stud 50a, and the complementary part 52a is a guide surface or oval opening 52a. Therefore, when the third jumper 50 is driven by the control gear 30, the third jumper 50 instantaneously displaces the first shaft A1 and the first indicator gear 10 in plane P, and acts the lever 52 to increase the intercenter space d1 between the indicator gears 10 and 20, i.e., between shafts A1 and A2. For this reason, the lever 52 and the jumper 50 may be the same part that pivots within the frame 90 around shaft A5 or A51.

[0044] The lever 52 is biased to its resting position by an elastic return element 51, which is included in the third jumper 50 in the embodiment described and illustrated. Furthermore, outside of the driving phase, the elastic return element 51 also allows the first disk 11 to be held relative to the second disk 21 such that there is a gap j1 of, for example, zero or substantially zero width l1.

[0045] In a stationary state, to optimally control the width l1 of the gap j1, it is preferable that the third jumper 50 positions the control gear 30 with a small gap to ensure that the first indicator gear 10 is precisely positioned relative to the second indicator gear 20 under the effect of the elastic return element 51. In this case, it is possible to ensure that in a stationary state, the first part 11b of the first indicator gear 10 precisely weights the second part 21b of the second indicator gear 20. Alternatively, this is possible to ensure that in a stationary state, the lever precisely weights the stopper, and as a result, the width l1 of the gap j1 is controlled.

[0046] One embodiment of the operating method of the present invention will be described below. This embodiment is, for example, a method for operating the display device, clock movement, or clock described above.

[0047] The operation method is as follows: during at least one display jump or at least a specific display jump, - A first step of displacement of the first shaft A1, which allows the first indicator gear 10 to be displaced relative to the second end in order to separate the first part 11b from the second part 21b from the stationary position of the first shaft A1, - Display change step, - The second step of displacement of the first axis A1 allows the first indicator gear 10 to be displaced relative to the second end in order to bring the first part 11b closer to the second part 21b until the first axis A1 reaches a stationary position. Includes.

[0048] In the embodiments described and illustrated, all three steps mentioned in the preceding paragraphs are performed for each display jump. These three steps mentioned in the preceding paragraphs form part of the driving stage described above.

[0049] During the drive phase, the first and second indicator gears 10 and 20 can be rotationally driven by the first and second tooth sets 31 and 32 of the control gear 30, respectively, in order to change the clock information displayed on the first and second indicator discs. The control gear 30 is driven by the drive gear 40 using a pawl 41 that cooperates with a third tooth set 33.

[0050] Simultaneously or substantially simultaneously, when the control gear 30 is moved using the pawl 41 cooperating with the set of teeth 33, the set of teeth 33 lifts the jumper 50, thereby displacing the first axis A1 and the first indicator gear 10 in plane P to increase the intercenter space d1 between the two indicator discs 11, 21. More specifically, in the embodiment described and illustrated, the stud 50a of the jumper 50 acts on the oval opening 52a of the lever 52 to pivot the lever 52 around its axis A1 and displace the first indicator gear 10 in plane P. In this way, the increase in intercenter space d1 makes the indicator gears 10, 20 rotatable without touching each other during the indicator change step, despite the fact that the discs 11, 21 have non-circular circumferences, as shown in Figure 3.

[0051] As the jumper 50 passes over the apex of the teeth of the tooth set 33, the jumper 50 is biased toward the bottom of the tooth set by the elastic return element 51, which in turn causes the lever 52 to begin to move toward its resting position.

[0052] Under the action of the first jumper 13, as soon as it passes the vertices of the teeth of the tooth set 12, the first indicator gear 10 completes its rotation so as to be indexed to the subsequent number 11a, as shown in Figure 4. Preferably, the rotation of the first indicator gear 10 must be completed before the lever 52 returns to its resting position.

[0053] Similarly, the second indicator gear 20 completes its rotation so that it is indexed to the subsequent number 21a under the effect of the second jumper 23. At the end of the drive phase, the first disk 11 again faces or substantially faces the second disk 21 under the effect of the elastic element 51 and is indexed by the first jumper 13 as shown in Figure 5.

[0054] Therefore, preferably, the first displacement step includes a first displacement of the first axis A1 starting from the stationary position of the first axis A1, and the second displacement step includes a second displacement of the first axis A1 until it reaches the stationary position of the first axis A1.

[0055] The display change step allows parts 11b and 21b, which were positioned opposite each other in the previous time before the change step, to be positioned opposite each other for the first time (to indicate subsequent clock information). In other words, when the first display gear 10 or the second display gear 20 is determined or positioned to the subsequent digits 11a and 21a, respectively (to indicate subsequent clock information), the subsequent parts 11b and 21b are positioned within the opening 201.

[0056] In the embodiments described and illustrated, preferably, if one of the two indicator gears 10, 20 is not rotationally driven by the control gear 30, for example, during passage from 30 to 31 or from 31 to 1, the first gear is still displaced in plane P during the drive phase to allow the discs 11, 21 to change the date without interference. In other words, in each drive phase, the lever 52 is operated in the same manner as before. However, the first set of teeth 31 or the second set of teeth 32 do not systematically cooperate with the first pinion 12 or the second pinion 22, respectively.

[0057] As a result of the above, the display changing step advantageously includes rotating the first display gear 10 around the first axis A1 and / or rotating the second display gear 20 around the second axis A2.

[0058] In the embodiments described and illustrated above, the first indicator gear is displaced relative to the frame 90, and the second indicator gear remains fixed to the frame (except for rotating around its own axis A2). Alternatively, regardless of the embodiment or modification, the second indicator gear may be displaced relative to the frame 90, and the first indicator gear may remain fixed to the frame (except for rotating around its own axis A1). Further alternatively, regardless of the embodiment or modification, the second indicator gear may be displaced relative to the frame 90, and the first indicator gear may be displaced relative to the frame 90. Preferably, the displacement of these gears is carried out in a plane P. In the latter two alternative examples, the second indicator gear is mounted to pivot on a second support that is displaceable relative to the frame 90, and the second support is different from any first support. The second support can preferably be displaced perpendicular to axis A2.

[0059] In the embodiment described and illustrated above, the support portion 52 is biased to a stationary position by the elastic element 51. Alternatively, regardless of the embodiment or modification, the support portion 52 may be actuated by the control gear 30 using a positive-acting mechanism connection.

[0060] In the embodiments described and illustrated above, the portions 11b and 21b visible from the opening in the stationary position of the display disc are linear. Alternatively, regardless of the embodiment or modification, the portions 11b and 21b visible from the opening in the stationary position of the display disc may have any complementary shape. These shapes may be curved, particularly convex or concave. These shapes may also include convex and concave regions. The portions 11b and 21b may have a zigzag or undulating shape. In particular, the second display disc may have a circular end or perimeter, and the first display disc 11 may have a portion 11b visible from the opening in the stationary position of the display disc, which is concave and complementary to the curvature around the second disc. In this case, the second disc can display, for example, the units digit of a clock, particularly the units digit of a date. With such a configuration, the support does not need to be displaced during a display jump resulting in only the rotation of the second gear 20, and the support is advantageously displaced only during a display jump resulting in the rotation of the first gear 10. In the case of a date display, the support is displaced only when the tens digit of the date is changed. Alternatively, the first display disc may have a circular end or perimeter, and the second display disc 12 may have a portion 12b that is concave and complementary to the curvature around the first disc, and is visible from the opening in the stationary position of the display disc. With such a configuration, the support does not need to be displaced during a display jump resulting in only the rotation of the first gear 10, and the support is advantageously displaced only during a display jump resulting in the rotation of the second gear 20.

[0061] Preferably, - One disk having a circular perimeter that displays one part of the information, particularly the units digit of a number, particularly the units digit of a date, and the part that changes in the first cycle, - The other disk has a peripheral portion of a complementary shape to the circular peripheral, which displays the other part of the information, particularly the tens digit of a number, particularly the tens digit of a date, and the peripheral portion of which is changed in a second cycle, the first cycle being higher than the second cycle, and the other disk. It is possible to use it.

[0062] More generally, the solution according to the present invention relates to an opening, - Not necessarily linear, and / or - Having a constant or non-constant and / or non-zero width l1, and / or - Having zero or non-zero width l1, The first and second disks may be adapted to have a gap j1 between them. In summary, as a result of the solution of the present invention, the gap shape can be defined freely and without limitation. For this reason, the visible portions 11b and 21b may have a straight or curved shape. Preferably, these portions are parallel (in a stable display state), i.e., the distance between portions 11b and 21b (measured perpendicular to the tangents of the ends) is constant.

[0063] Regardless of the embodiment or modification, the gap (or width l1) is less than 0.2 mm, less than 0.1 mm, or less than 0.05 mm. Therefore, the first and second gears are advantageous in that, in a stable state displaying clock information, the first part 11b and the second part 21b are, - To come into contact with each other, or - The structure provides a gap between the first part 11b and the second part 21b that is less than 0.2 mm, less than 0.1 mm, or less than 0.05 mm. They are arranged in this manner.

[0064] The solutions according to the present invention are not limited to the display of dates, but can be used for any information that can be displayed on a disk, such as the year, month, day of the week, number of hours, number of minutes, or any numerical or alphanumeric representation using numerical or letter jumps.

[0065] The combination of disks may also be used to display lunar phases. In this example, each disk may form part of the display, in particular half of the lunar display. More specifically, the first disk contains the first part of the display of various lunar phases, and the second disk contains the second part of the display of various lunar phases, complementary to the first part. More generally, the combination of disks may also be used to display specific shapes, symbols, or even pictograms.

[0066] Alternatively, in a modified example (not shown) where only one indicator gear is required for displaying information, the second part 21b may form part of a fixed border of the second part, such as the second end of the frame, or the second end of the dial, opening, flange, or blank.

[0067] As an alternative to the embodiment described and illustrated, one or more intermediate gears may be positioned between the control gear 30 and the pinion 12 and / or pinion 22 and / or drive gear 40.

[0068] In the embodiments described and illustrated above, the support 52 is actuated by the control gear 30 to increase the intercenter space d1 between the disks 11 and 21. Alternatively, regardless of the embodiment or modification, it is not essential that the support 52 be actuated by the control gear 30 to increase the intercenter space d1 between the disks 11 and 21. Specifically, the support may simply be shifted or displaced by the action of one disk on the other disk during the rotation of both or during the rotation of one of them. Alternatively or additionally, the displacement of the movable support supporting the indicator gear may be displaced by the mechanical action of the tooth set 31 on the tooth set 12.

[0069] The jump occurs at a frequency defined based on the displayed clock information, typically every 24 hours for date or day of the week information.

[0070] In the embodiments described and illustrated above, the displacement steps due to moving away from and approaching each other are displacement steps in rotation around the third axis A51, in particular, the first axis A1 and the second axis A2 are separated from each other in rotation around the third axis A51. However, alternatively, regardless of the embodiment or modification, the displacement steps due to moving away from and approaching each other may be translational displacement steps. In such a case, the lever 52 may be replaced by a sliding support on which the first gear 10 is pivotable, and which is movable translationally relative to the frame 90.

[0071] Preferably, regardless of the embodiment or modification, the steps of displacement by moving away, changing the display, and displacement by approaching are performed in succession. Alternatively, - The step of changing the display may be performed while the step of displacement by moving away has already been started but not yet completed, and / or - The step of displacement by approaching may be performed while the step of changing the display has already started but not yet completed, but the step of changing the display must be completed before the step of displacement by approaching is completed.

[0072] Preferably, regardless of the embodiment or modification, - The first set of teeth 31 forms part of the second set of teeth 32, and / or - The first set of teeth 31 and the second set of teeth 32 are formed at the same height, and / or - On one side, the first set of teeth 31 and one of the second set of teeth 32, and on the other side, the third set of teeth 33 are formed to the same height.

[0073] Preferably, regardless of the embodiment or modification, the jump is instantaneous or substantially instantaneous. Preferably, as herein, “instantaneous jump” is understood to mean a jump that lasts on the order of a fraction of a second, typically about 1 / 100th of a second, or about 1 / 25th of a second, or even about 1 / 10th of a second. Preferably, as herein, “substantially instantaneous” means a jump that lasts on the order of a few seconds, for example, between 1 second and 10 seconds.

[0074] Therefore, according to the present invention, - The shape of the area around the display disk, and / or - The gap between disks in the (optionally removable) opening, There is a high degree of flexibility in its definition.

[0075] The solutions of the present invention enable the use of two juxtaposed display disks while limiting the gap or space between disks and providing a high degree of freedom in defining the shape around the disks. More specifically, these solutions enable the acquisition of a linear gap of any width, which may be zero. This advantageously allows for the implementation of a single, undivided opening for displaying a date, in contrast to two openings where one opening displays the tens digit and the other displays the units digit.

[0076] Finally, the solution according to the present invention requires less space, particularly on the disk, than known solutions from the prior art. [Explanation of Symbols]
