Description

Technical field of the invention

[0001] The present invention relates to an arrangement of a display module on / in a plate. More specifically, the invention relates to a watch assembly comprising a watch display module and a plate of a watch movement of the watch. Technological background

[0002] In the state of the art, it is known to produce an arrangement on a plate of a display module consisting solely of a dial by a technique of locking the legs of this dial by means of corresponding dial keys.

[0003] One of the disadvantages of this technique is that the dial legs are fragile and can easily break if impacted. Since the dial legs themselves are not repairable, the entire dial must be replaced, provided that it is still available as a spare part, which is not always the case.

[0004] In this context, it is therefore understandable that there is a need to find an alternative solution to that of the state of the art. Summary of the invention

[0005] One aim of the invention is to overcome the above-mentioned and other drawbacks by providing a watch assembly in which a watch display module is arranged on / in a plate using novel arrangement techniques that are discreet, simple, and reliable.

[0006] The invention relates to a watch assembly comprising a watch display module and a plate of a watch movement of the watch, the display module being provided with at least one display component and a protective element including an open housing in which is arranged said at least one display component provided with a visible face positioned opposite a fully or partially transparent back of this housing, said protective element comprising tabs participating in the arrangement of this element in the plate.

[0007] In other embodiments: the plate comprises a cavity for each tab, the cavity including an enclosure opening through an opening on an upper face of this plate, said enclosure being configured to receive the tab of the protection element; the plate comprises a cavity for each tab provided with an enclosure capable of receiving this tab and in which enclosure, a fixing element is capable of being in contact with this tab to ensure the fixing of this tab in this enclosure; the plate comprises a through hole extending from the side wall of the plate into the enclosure of each cavity, said hole being configured to receive a fixing element of the tab to participate in the fixing of this tab in said enclosure; each cavity extends in a thickness of the plate in a direction perpendicular or substantially perpendicular to the upper face of this plate;the cavity extends in the thickness of the plate in a direction parallel or substantially parallel to the side wall of the plate; the protective element comprises a support element provided with a contact surface intended to bear on the plate when the display module is arranged in this plate; the support element also comprises an element for positioning the module relative to the plate; the tabs and the support element are an extension of the end of a peripheral wall of the protective element delimiting an opening of its housing; the plate comprises an orifice opening on its upper face configured to receive said positioning element; the display module comprises a pivoting element kinematically connected to a mechanism of the watch movement of the watch and which is configured to cooperate with the display component of this module to cause its movement. ;

[0008] Another aspect of the invention relates to a watch comprising such a watch assembly. Brief description of the figures

[0009] Other characteristics and advantages of the invention will appear more clearly on reading the following description of a particular embodiment of the invention, given as a simple illustrative and non-limiting example, and the appended figures, among which: THE figures 1 And 2 are exploded perspective views of a watch assembly comprising a watch display module and a plate, according to one embodiment of the invention; the Figure 3 is a perspective view of this watch assembly with the display module arranged in / on the plate, according to the embodiment of the invention; Figure 4 is a representation of a top view of the watch assembly with the display module arranged in / on the plate, according to the embodiment of the invention, and the Figure 5 is a sectional view VV of the Figure 4 , according to the embodiment of the invention. Detailed description of the invention

[0010] On the figures 1 to 5 , a watch assembly 10 of a watch, in particular a wristwatch, is shown. Such an assembly 10 is included in this watch, which may be a wristwatch. In this assembly 10, a display module 1 is arranged in / on a plate 2 of a watch movement of this watch. Such an assembly 10 therefore comprises this display module 1 and the plate 2. It will be noted that such a display module may be, in a non-limiting and non-restrictive manner, related to: a quick correction selector indicator of this watch, or a date display.

[0011] In this configuration, the display module 1 comprises at least one display component 4, a protective element 3 and a pivoting element 5. The display component 4 is a mobile timepiece, preferably mobile in rotation, which participates directly in the selection, presentation and / or indication of timepiece information. In other words, this component 4 may comprise a graphic representation specifically participating in this selection or may be configured, for example in its shape, to carry out this selection, or this component 4 comprises at least one graphic representation corresponding to the timepiece information to be displayed / presented and which will therefore be selected for this. This component 4 may be, in a non-limiting and non-exhaustive manner, a dial or a hand.In the present embodiment, this component 4 may be a mobile part rotating around its axis of revolution A, for example here a mobile dial or a mobile hand. In this configuration, it will be noted that such a display component 4 can therefore be driven in this rotational movement by the pivoting element 5 such as a pinion which is kinematically connected to a mechanism of the watch movement of the watch. Such a pivoting element 5 passes through a passage zone 16 of the plate 2 by connecting the display component 4 to this mechanism. It will be noted that such a mechanism can be configured for the implementation of a rapid correction selector indicator.

[0012] As we have specified, this display component 4 can be a dial as seen on the figures 1 to 5. In this configuration, this dial can then be fixed by driving at its mounting zone 21, on a first end of the pivoting element 5 forming a pivot. It will be noted that the second end of this pivoting element 5 also forming a pivot, can be mounted in a bearing, in particular a shock-absorbing bearing.

[0013] Such a dial comprises a visible face 8 comprising at least one graphic representation participating in the selection, presentation and / or indication of horological information. It will be noted that when this component 4 is a hand, the latter can also be driven onto this pivot of the pivoting element 5.

[0014] In this display module 1, the protective element 3, also called a cover or mask, comprises an open housing delimited by a peripheral wall 15 and a base that is wholly or partly transparent. This housing is defined in particular to accommodate or receive the display component 4. With reference to figures 1 to 3 , this protection element 3 is formed of two parts 7a, 7b: a first part 7a of essentially annular shape provided with opposite openings of substantially the same section and which are connected to each other by said peripheral wall 15, and a second part 7b in whole or in part transparent intended to be mounted in one of the two openings in order to form the bottom of the housing defined in the protective element 3.

[0015] More specifically, this second part 7b may be a mirror and is mounted in the first opening of the first part 7a. It is understood that this first opening is specifically configured to be assembled to such a second part 7b.

[0016] We therefore understand that in this protection element 3, this second part 7b can be: entirely / completely transparent by including graphic representations corresponding to watch information, the selection and / or presentation of one of these pieces of information of which is carried out by a display component 4 such as a hand; entirely / completely transparent by including graphic representations corresponding to watch information, the selection and / or presentation of one of these pieces of information of which is carried out by a display component 4 such as a dial, the visible face 8 of which includes a graphic representation, for example an arrow or the representation of a hand;entirely / completely transparent by including a graphic representation for example an arrow or the representation of a hand which carries out the selection and / or the presentation of information from among watchmaking information included in graphic representations present on the visible face 8 of a display component 4 such as the dial; ; partly transparent while being completely opaque except for a part of this part 7b which is transparent and which, like a window, carries out the selection and / or the presentation of information from among watchmaking information included in graphic representations present on the visible face 8 of a display component 4 such as the dial; partly transparent while being completely opaque except for an opening included in this part 7b which, like a window, carries out the selection and / or the presentation of information from among watchmaking information included in graphic representations present on the visible face 8 of a display component 4 such as the dial.

[0017] It will be noted that in this first part 7a, the second opening which is defined at the end of the peripheral wall 15 of this part, therefore comprises an edge 19 of this part 7a described by this end.

[0018] In this configuration, such a first part 7a comprises tabs 6a, 6b which participate in the arrangement of the display module 1 in / on the plate 2. Such tabs 6a, 6b in this embodiment of this module 1, are in a non-limiting and non-exhaustive manner two in number. These tabs 6a, 6b are each an extension of the peripheral wall 15 of this first part 7a by extending vertically in a direction which is parallel or substantially parallel to the axis of revolution A, when this protection element 3 is mounted on the plate 2. In this context it is understood that these tabs 6a, 6b are an extension of this peripheral wall 15 starting from the edge 19 of this first part 7a.

[0019] In addition, such a first part 7a also comprises a support element 20 provided with a contact surface 18 intended to bear on the plate 2 when the display module 1 is arranged in this plate 2. Just like the tabs 6a, 6b of the first part 7a, the support element 20 is also an extension of the peripheral wall 15. Such a support element 20 comprises a positioning element 6c of the display module 1 relative to the plate 2. This positioning element 6c is a protrusion or a relief included on the contact surface 18 of the support element 20. This positioning element 6c is an extension of the support element 20.

[0020] In this assembly 10, the plate 2 preferably has a general shape similar to that of the watch case. This plate 2 comprises upper and lower faces 11a, 11b as well as a side wall 11c which connects these faces 11a, 11b together. Such upper and lower faces 11a, 11b are included in planes which are parallel or substantially parallel to each other.

[0021] Such a plate 2 comprises cavities 9a, 9b configured to receive the tabs 6a, 6b of the protection element 3 and by extension the tabs 6a, 6b of the display module 1. Each cavity 9a, 9b comprises an enclosure opening onto the upper face 11a. In other words, the cavity 9a, 9b comprises a passage opening 13a, 13b in the enclosure which is included in this upper face 11a of the plate 2.

[0022] This cavity enclosure 9a, 9b extends in the thickness of the plate 2 in a direction perpendicular or substantially perpendicular to the upper face 11a. It will be noted that this enclosure extends, towards the lower face 11b of the plate 2, in a direction which is parallel to the axis of revolution A of the display component 4. With reference to the Figure 1 , this cavity 9a, 9b may have an oblong shape. In other words, a section of the enclosure may have this oblong shape.

[0023] This plate 2 also comprises a through hole 14a, 14b for each cavity 9a, 9b. This through hole 14a, 14b comprises two openings, one opening opening into the enclosure of this cavity 9a, 9b and another into an external face of the side wall 11c of the plate 2. This through hole 14a, 14b comprises a housing defined between these openings, in which a fixing element 17a, 17b of the tab 6a, 6b positioned in the enclosure of the cavity 9a, 9b can be arranged. In other words, this housing is configured to receive a fixing element 17a, 17b, one end of which can protrude into the enclosure to come into contact with the contact surface 18 of the tab 6a, 6b positioned opposite the second opening of this hole 14a, 14b, in order to ensure the fixing of the tab 6a, 6b in this enclosure.In such a configuration, this housing is configured so that the other end of this fixing element 17a, 17b does not protrude from the external face of the side wall 11c when this fixing element 17a, 17b ensures the maintenance of the tab 6a, 6b in the enclosure. This through hole 14a, 14b extends rectilinearly from the side wall 11c towards the enclosure in a direction which is perpendicular or substantially perpendicular to that of cavity 9a, 9b in the thickness of the plate 2. In other words, the central axis B, C of this through hole 14a, 14b is perpendicular or substantially perpendicular to the direction of the axis of revolution A. Such a through hole 14a, 14b has a length which is greater than that of the fixing element 17a, 17b in order to conceal this fixing element 17a, 17b in the plate 2. It will be noted that this hole 14a, 14b can be tapped to cooperate with a fixing element 17a, 17b such as a screw.

[0024] Furthermore, this plate 2 also comprises an orifice 12 for receiving the positioning element 6c. Such an orifice 12 has a shape which is complementary to that of the positioning element 6c.

[0025] Thus, in this assembly 10, the arrangement of the display module 1 on the plate 2 is achieved in particular by: fixing the legs 6a, 6b of the protective element 3 in the cavities 9a, 9b of the plate 2 from the fixing elements 17a, 17b which come to bear on the contact surfaces 18 of the legs 6a, 6b; bearing on the upper face 11a of the plate 2 of the protective element 3 from its support element 20; holding the protective element 3 in its mounting position on / in the plate 2 from the arrangement of the positioning element 6c in the orifice 12 provided in the plate 2; holding the display component 4 in the housing of the protective element 3 from the pivoting element 5.
