DISPLAY MECHANISM FOR CLOCK

Description

technical field

[0001] The present invention relates to a display mechanism for a watch movement comprising a plate defining a general plane, the display mechanism comprising a support intended to be assembled at least indirectly to the plate and on which is mounted a rotating display member carrying at least one display surface carrying at least one piece of information to be displayed, associated with a predefined instant or a predefined event, the display surface being intended to be driven in rotation between at least first and second different positions around the axis of rotation of the display member, the support being arranged in such a way that the axis of rotation of the display member is oriented to present an inclination of between 10 and 80 degrees with reference to the general plane. State of the art

[0002] We know of timepieces featuring a large date display mechanism that include two discs, sometimes arranged coaxially, and generally pivoted directly on the mainplate of the corresponding watch movement or on an additional plate. These mechanisms notably allow for a reduction in the size of the date display in a plane parallel to the overall plane of the corresponding watch movement, without reducing the size of the numerals on the display discs. figure 1a illustrates such a display applied to an alternative quantity, used here for illustrative purposes only and without limitation. Indeed, the display mechanism of the figure 1aThis display is designed to show a user's par while playing golf. Of course, this display mechanism could also be used to show the score of a round of golf. The need to display three digits side-by-side, illustrated as a non-exhaustive example, amplifies the perceived bulk of such a display. In this case, it is difficult to define a suitable compromise between the display's size and its readability, especially if it is intended for use in a wristwatch.

[0003] There figure 1bThis illustrates a known alternative display mechanism employing display elements in the form of cylinders or rollers arranged so that their common axis of rotation is oriented in a direction parallel to the general plane of the corresponding watch movement (the bearing supports are not shown for the sake of simplicity). Considering that such a display mechanism is superimposed on the standard thickness of the watch movement, it becomes clear that the overall thickness of the corresponding timepiece is quite significant, particularly due to the large diameter of the unit cylinder.

[0004] Other display mechanisms are also known, designed to offer greater freedom in the construction of the corresponding watch movements in terms of their size. For example, patent application CH702422 describes an orbital time display mechanism that meets the characteristics stated in the preamble. This mechanism includes a support intended to be mounted to the mainplate of the corresponding watch movement so that it can rotate relative to the center of the movement. The support carries a subdial comprising a crown with hour markers to display the current time, as well as an hour hand that aligns with these markers.The subdial and hour hand are driven to rotate in a constant orientation relative to the mainplate, regardless of the support's position relative to it (i.e., so that the 12 o'clock marker is always positioned at 12 o'clock according to the classic horological reading convention). The hour hand is also driven, by a combined drive, to rotate relative to the crown and display the current time. The common axis of rotation of the crown and the hour hand is inclined outwards, relative to a general plane of the mainplate, to free up space in the center of the watch movement for other components.The hour hand is flat and describes a disc as it completes a full rotation of the subdial. The crown is inclined relative to the plane of this disc, so as to be contained within a portion of a cone whose apex angle is preferably equal to the angle of inclination of the subdial's axis of rotation relative to the mainplate's plane. While this patent application allows for an inclination angle greater than 15 degrees (although it is preferably less than this), such a scenario seems impractical. Indeed, reading the current time could prove problematic in this case, particularly when the crown's graduation corresponding to the time to be indicated at a given moment is located near the periphery of the watch movement, where the crown would exhibit its maximum inclination relative to the mainplate's plane.In general, reading the current time is difficult in any case, especially with a significant angle of inclination, since it is done by reading the relative positions of the hour hand and the crown markings, which are located on planes inclined to each other. Thus, the benefit of this invention, in terms of saving space in the center of the watch movement, seems limited by a necessary restriction of the angle of inclination, without which the readability of the corresponding information becomes significantly impaired.

[0005] It therefore appears that, for the time being, the manufacturer has few options for creating a legible display with a footprint suited to its needs, particularly to accommodate the presence of any additional complications in the timepiece it is to build. If it must limit the footprint of such a display mechanism, it must accept a significant increase in overall thickness.

[0006] It is indeed desirable to provide, according to the present invention, that the display surface is driven so as to be located substantially in a plane parallel to the general plane in its first position, at the predefined time or when the predefined event occurs, in order to define a reading position in which the conditions for reading the information by a user are optimal, the conditions for reading the information being degraded when the display surface is in its second position.

[0007] Furthermore, according to the present invention, it is more specifically provided that the display mechanism includes an additional display element, oriented to pivot about an additional axis of rotation having an inclination between 10 and 80 degrees with reference to the general plane, and carrying at least one additional display surface intended to be driven in rotation between at least two different positions around the additional axis of rotation, such that it is located substantially in a plane parallel to the general plane in one of its positions to define a reading position.

[0008] Patent CH 701653 B1 describes a display mechanism comprising a plurality of display elements arranged in substantially radial directions, slightly inclined with respect to a general plane of the display mechanism, each preferably having three display surfaces of different appearances, for example, different colors, only one of which is visible at a time in a reading position. In particular, this document provides for displaying the current time by implementing twelve such display elements, arranged according to the usual positions of the hour markers on a watch dial. However, the nature of the information that can be displayed by such a display mechanism and the number of display surfaces that each display element can have appear to be relatively limited.

[0009] Thus, it could prove useful for the watchmaker to have a new option at their disposal, different from known constructions, to have more flexibility in the construction of a watch movement including a display mechanism of the type mentioned above. Disclosure of the invention

[0010] A main objective of the present invention is to propose a display mechanism for watch movements offering an alternative presentation in reference to known watch parts in terms of display, in particular good readability obtained despite a footprint in the plane smaller than that of a disc display, and a footprint in the direction of the thickness of the watch movement smaller than that of a cylinder display, without however presenting the limitations of the prior art mentioned above.

[0011] To this end, the present invention relates more particularly to a display mechanism of the type indicated above, characterized by the fact that the additional axis of rotation is substantially parallel to the axis of rotation of the first display element, being arranged in such a way that the reading position of the additional display surface is adjacent to the reading position of the first display surface.

[0012] Thanks to these features, the watchmaker can determine the best compromise, according to their own needs, regarding the spatial distribution of the display mechanism's footprint according to the invention, unlike the case of certain prior art displays. Furthermore, the display mechanism according to the invention provides an absolute, rather than relative, reading of the display surface's position. It is sufficient for the display surface to be located in a plane parallel to the general plane of the mainplate, in the reading position, for the user to see the corresponding information. Thus, compared to the construction of application CH702422, for example, it is sufficient for the display surface bearing the number 3 to be in the reading position for the user to know that it is 3 o'clock, in the case of a time display.When displaying other information, such as PAR, the display area corresponding to a user-defined setting—that is, in response to a predefined event—is located in the read position. No other components are required to perform a read-only display of the relative positions between two components of the display mechanism, as is the case with this earlier design. Furthermore, this read position is easily identifiable by the user since the reading conditions are optimal there, whereas the reading conditions for the information displayed on the screen are significantly degraded when it is not in its read position.A comparative examination of the various visible display surfaces (since some may be obscured due to a significant inclination relative to the plane parallel to the overall plane of the display) easily identifies the one in the reading position as offering the best reading conditions, due to its virtually zero angle of inclination relative to the overall plane of the display. Finally, the relative arrangement of the display surfaces of the different display elements increases display possibilities, particularly in terms of the information to be displayed, in reference to the prior art mechanisms mentioned above.

[0013] Preferably, the display mechanism is arranged so that its display surface is located in a plane intersecting the general plane at least in its second position.

[0014] Of course, while the reading position is very easily identifiable in the case of a jumping display, because the tilt of the display surface between its reading position and adjacent positions varies to a greater or lesser extent (particularly depending on the number of display surfaces in the display, which influences the step between two successive positions), a margin of error can be allowed regarding the parallelism between the display surface and the mounting plate in the case of a trailing display. Indeed, the reading conditions for the information displayed on the display surface can be considered optimal when its tilt relative to the parallel plane is within a range of plus or minus 15 degrees, preferably plus or minus 10 degrees.Of course, this margin of appreciation depends on the number of different display surfaces that the display device carries, and a person skilled in the art will not encounter any particular difficulty in adapting this teaching to suit their own needs, without going out of the scope of the invention defined by the attached claims.

[0015] Furthermore, it is advantageous to provide that the display unit has at least two, preferably up to twelve, display surfaces.

[0016] In this case, it is preferable to plan for the display surfaces to be regularly distributed around the axis of rotation, being arranged approximately along a portion of a cone.

[0017] According to a preferred embodiment, the display element may be provided to carry a first toothed board, preferably a first star, arranged along the axis of rotation and in contact with a second toothed drive board, preferably a second star, oriented so as to be contained in a plane substantially parallel to the general plane, the second toothed board having a kinematic link with a drive unit intended to be driven by the clock movement or under the effect of a predefined action of a user on a control element.

[0018] In this case, it is advantageous to provide that the display mechanism includes a positioning jumper for the display element arranged to cooperate with the second toothed board.

[0019] According to a preferred embodiment, the display surface and the additional display surface can be arranged in such a way that they are positioned adjacent to each other only when they are simultaneously in their respective reading positions.

[0020] Furthermore, it is advantageous to provide that the first display element carries a pin arranged to actuate a star-shaped component attached to the additional display element, advancing the latter by at least one step with each complete rotation of the first display element. Preferably, this star-shaped component is then secured to the additional display element in such a way that it has angular play relative to the latter, along the additional axis of rotation.

[0021] When the display mechanism includes an additional display element, the additional rotation axis can be provided for to be separate from the first rotation axis. The display mechanism includes an additional support intended to be assembled, at least indirectly, to the main plate, and on which the additional display element is rotatably mounted. The support can then be provided for to carry a positioning element arranged to cooperate with an additional star, integral with the additional display element, to ensure the correct positioning of the additional display element relative to the additional rotation axis.

[0022] In general, it can be expected that the additional display unit will carry at least two, preferably up to twelve, additional display surfaces.

[0023] The present invention also relates to a watch movement comprising a plate supporting a display mechanism according to the preceding characteristics, as well as a timepiece comprising such a watch movement. Brief description of the drawings

[0024] Other features and advantages of the present invention will become more apparent upon reading the detailed description of a preferred embodiment that follows, made with reference to the accompanying drawings given by way of non-limiting example and in which: there figure 1a represents a simplified front view of a display mechanism according to a first embodiment of the prior art, the figure 1b represents a simplified perspective view of a display mechanism according to a second embodiment of the prior art, and the figure 1crepresents a simplified perspective view of a display mechanism according to a preferred embodiment of the present invention, the figure 2 represents a partial and simplified perspective view of a construction detail of the display mechanism of the figure 1c , and the figure 3 represents a simplified front view of part of a timepiece incorporating a display mechanism according to the figure 1c . Method(s) of embodiment of the invention

[0025] There figure 1c represents a simplified perspective view of a display mechanism 1 according to a preferred embodiment of the present invention, allowing comparison of the respective dimensions of the various prior display mechanisms ( Figures 1a and 1b ) and the display mechanism according to the present invention, for given display dimensions.

[0026] More specifically, the display mechanism 1 visible on the figure 1cis here intended to display the PAR of a user in the context of playing golf, as a non-limiting illustrative example.

[0027] For this purpose, the display mechanism 1 includes a first unit display element 2 associated with an additional tens and hundreds display element 4.

[0028] The display element 2 of the units comprises a hub 6 from which extend ten arms 8, regularly distributed around the hub 6, and each of which carries a paddle defining a display surface 10 of a number between 0 and 9. The arms 8 and / or the display surfaces 10 have an inclination with respect to the mean plane of the hub 6 in such a way that the display surfaces 10 are distributed substantially along a portion of a cone.

[0029] We can also distinguish the teeth of a first toothed board 12, here the branches of a first star, coaxial with the hub 6 and attached to it to allow the drive of the display organ 2 in rotation as will be described later.

[0030] The display element 2 is intended to be mounted rotatably on a component of a watch movement, typically a mainplate, by means of a support (numerical reference 14 on the figure 3 ) featuring a bearing arranged in such a way that the display organ 2 is pivoted along an axis of rotation inclined with reference to a general plane of the clock movement plate, advantageously at an angle between 10 and 80 degrees.

[0031] Thus, by its shape and orientation, the display element 2 can present its display surfaces 10 in a reading position in turn. In other words, each display surface 10 has a plurality of different positions around the axis of rotation of the display element 2, one of these positions being such that the display surface 10 is located in a plane substantially parallel to the general plane of the turntable to define this reading position. On the view of the figure 1cThe 0 is in this reading position. It is evident that the reading conditions of the display surface in this reading position are optimal, especially compared to the significantly degraded reading conditions of other display surfaces not in this position. Of course, the extent to which reading conditions are degraded outside the reading position depends heavily on the number of display surfaces on the display element 2, as the number of display surfaces affects the relative tilt between two adjacent display surfaces.

[0032] It may be advantageously provided, preferably, that the reading position is unique, the reading conditions being clearly degraded in all other positions, to avoid any doubt when reading the information displayed by the display element 2. Not only do the display surfaces located in positions adjacent to the reading position then have a visible inclination for the user, but some other positions may not allow at all to read the information carried by the display surfaces concerned.

[0033] The additional display element 4 for the tens and hundreds includes a hub 16 from which extend six arms 18, regularly distributed around the hub 16, and each of which carries a pallet defining a display surface 20 of two digits, here 07, 08, 09, 10, 11 and 12. The arms 18 and / or the display surfaces 20 have an inclination with respect to the mean plane of the hub 16 such that the display surfaces 20 are distributed substantially along a portion of a cone.

[0034] The additional display element 4 is also intended to be mounted rotatably on the movement plate, by means of a support 24 having a bearing arranged so that the additional display element 4 is pivoted along an axis of rotation inclined with reference to the general plane of the plate, advantageously at an angle between 10 and 80 degrees.

[0035] Thus, by its shape and orientation, the additional display element 4 can also present its display surfaces 20 in a sequential reading position, this reading position being adjacent to that of the display surfaces 10 of the display element 2 of the units. In other words, each display surface 20 has a plurality of different positions around the axis of rotation of the additional display element 4, one of these positions being such that the display surface 20 is located in a plane substantially parallel to the general plane of the turntable to define this reading position. On the view of the figure 1c , the 07 is here in this reading position, and we can therefore read the value 070 thanks to the two display surfaces 10, 20 located in the two reading positions.

[0036] Preferably, the display surfaces 10 and the display surfaces 20 of the additional display element 4 are arranged so that they are positioned adjacent to each other only when they are simultaneously in their respective reading positions.

[0037] There figure 2 represents a partial and simplified perspective view of a construction detail of display mechanism 1.

[0038] The display unit 2 has a pivot 26 housed in the bearing of the support 14 (not visible on the figure 2 (for more clarity). Of course, a person skilled in the art will be able to reverse the assembly of the display element 2 on the support 14 without departing from the scope of the invention as defined by the annexed claims, i.e. provide that the support 14 carries a fixed shaft around which is engaged a barrel integral with the display element 2.

[0039] The drive mode of the display element 2 according to this embodiment is visible on the figure 2 It can indeed be anticipated that the display mechanism 1 comprises a second toothed plate 28, also a star here, arranged to mesh with the first toothed plate 12 of the display element 2

[0040] Advantageously, the second toothed plate 28 is oriented here so as to be contained in a plane substantially parallel to the general plane of the plate, the latter having a kinematic link, via a wheel 30 to which it is attached, with a drive unit 32 intended to be driven by the clock movement or under the effect of a predefined action of a user on a control element.

[0041] A jumper 34 cooperates with the second toothed board 28 to ensure the required orientation of the display member 2 with reference to its axis of rotation, via the first and second toothed boards 12, 28.

[0042] Furthermore, the rotational drive of the additional display element 4 is provided here directly by the display element 2 of the units, by way of non-limiting illustration. To this end, the display element 2 includes a drive pin 36 for the additional display element 4, integral with its hub 6 and intended to cooperate with the additional display element 4 once per complete revolution of the display element 2 of the units.

[0043] The additional display element 4 also includes a pivot 38 housed in the bearing of the support 24 (not visible on the figure 2(for more clarity). The hub 16 carries a shaft 40, oriented along the axis of rotation of the additional display member 4, at the end of which is arranged a star 42 intended to be driven by the pin 36 of the display member 2 of the units to rotate the additional display member 4 by one step at each complete turn of the display member 2 of the units.

[0044] It is advantageous to provide that the star 42 is made fixed to the shaft 40 in such a way as to present a certain angular play to secure a transmission between the two display elements in both directions of rotation and avoid double jumps.

[0045] Furthermore, the support 24 advantageously carries a positioning element (not visible) arranged to cooperate with the arms of an additional star 44, attached to the hub 16, to ensure the correct positioning of the additional display element 4 in reference to its axis of rotation.

[0046] Il emerges from the view of the figure 2 that the respective axes of rotation of the two display elements are parallel but offset, by way of non-limiting illustration, the latter being shaped in such a way that their display positions are indeed adjacent.

[0047] Of course, it is possible to provide as an alternative that the rotation axes of the display elements are aligned, and that a single support is implemented, either to directly carry both display elements, or to carry only one of them, which then carries the other.

[0048] There figure 3 This represents a simplified front view of a portion of a timepiece 100 incorporating the display mechanism 1 just described. The timepiece 100 comprises a case 102 housing a watch movement 104, the construction of which is of little importance for the implementation of the display mechanism according to the present invention.

[0049] The watch movement 104 will therefore not be described in detail for the sake of simplicity. It comprises a time base 106 whose oscillations are maintained by a mainspring 108, housed in a barrel 110, via a finishing gear train 112, in a conventional manner. The finishing gear train 112 is arranged to drive the rotating components for displaying the current time via a wheel 114 and an hour wheel 116.

[0050] The watch movement 104 also includes a winding and correction mechanism 118, actuated by a winding and correction stem 120 that can occupy three different axial positions: one winding position and two correction positions. The winding and correction mechanism 118 includes, in particular, a rocker arm (not shown) carrying a set of correction gears 122 whose orientation depends on the axial position of the stem 120, thus establishing a kinematic link between the stem and a different correction mechanism in each axial position. In one axial position, the rotation of the stem 120 corrects the angular position of the current time display elements, while in the other axial position, the rotation of the stem 120 is transmitted to a first gear 124.The latter has a kinematic link with the drive unit 32, comprising here two additional links 126 and 128 (under the hour wheel 116), the drive unit 32 itself being engaged with the display element 2 of the units via the second toothed plate 28 and the wheel 30.

[0051] Thanks to this construction, a rotation of the rod 120 in one direction or the other, when it is in its corresponding axial position, makes it possible to correct the PAR value displayed by the display mechanism 1, between the values ​​070 and 129.

[0052] On the figure 3The display mechanism 1 has been intentionally positioned partially above the barrel 110 to better highlight the space-saving advantage of the present invention. Indeed, the specific construction of the display mechanism 1 according to the invention allows it to be installed in this case in the immediate vicinity of the barrel 110, which is generally the bulkiest component of a watch movement, and by arranging the reading positions of the display elements 2 and 4 above the barrel 110. Such an arrangement would not be possible with a cylinder display mechanism, while a readable disc display mechanism would occupy a significant portion of the available surface area in a plane parallel to the mean plane of the watch movement (generally parallel to the overall plane of the mainplate).

[0053] The display mechanism 1 is illustrated here with the rotation axes of the display elements 2 and 4 having the same inclination, approximately 45 degrees, relative to the general plane of the mainplate. However, this is of course a non-limiting example; the angle of inclination of each rotation axis can vary between 10 and 80 degrees to accommodate the specific characteristics of the watch movement in which the display mechanism is installed. In this case, the display surfaces have an inclination of approximately 45 degrees relative to the rotation axis of the corresponding display element.

[0054] Thanks to the features just presented, we obtain a display mechanism offering great flexibility to the watchmaker, to distribute the bulk in a watch movement according to their needs, while offering excellent readability.

[0055] Of course, while it is possible to provide for the display mechanism according to the invention to include a window or cover to facilitate the identification of the reading position, such a measure is only optional since a comparative examination between the reading position and other positions makes it easy to identify the reading position, due to a significant difference between their respective reading conditions. Indeed, the aim here is not solely to assess whether a given display surface is parallel or not to the general plane of the turntable, but rather to assess the relative reading conditions between adjacent positions, which makes it possible to identify without any doubt which position corresponds to the reading position.It should also be noted that, although not absolutely necessary (particularly in the case of a trailing display), the identification of the reading position is simplified if the display surfaces are individualized, as is the case in the preferred embodiment which has been illustrated as a non-limiting example.

[0056] The preceding description focuses on describing a particular embodiment by way of non-limiting illustration, and the invention is not limited to the implementation of certain specific features described above. Thus, for example, the implementation of the present invention is not limited to displaying the aforementioned quantity, namely PAR during golf practice, and a person skilled in the art will not encounter any particular difficulty in adapting this teaching and creating a display mechanism that meets the claimed characteristics but is implemented in connection with the display of another quantity, whether the display mechanism is driven by the watch movement or in response to a user action on a crown or pusher, for example. The same applies to the construction of the display mechanism's actuation mechanism as described and illustrated.For example, the first and second stars 12 and 28 could be replaced by bevel gears. Furthermore, as previously mentioned, when the display mechanism includes several display elements, each could be driven independently of the others, as an alternative to what has just been illustrated and described.

[0057] Finally, it should also be noted that, depending on the type of construction implemented, a person skilled in the art will be able to produce a trailing display (for example, the display of measured time seconds) or a jumping display according to their own needs.
