Definitions

  • the present invention relates to a dial plate, a connecting ring for such a dial plate, and a dial itself comprising the assembly of a dial plate and a connecting ring. It also relates to a timepiece incorporating such a dial, such as a wristwatch.
  • a dial for a watch part is described by the document EP3339970
  • Such a dial design includes feet welded beneath a dial plate, intended for securing the dial plate to a watch case, for example, with screws.
  • This solution has the drawback of requiring a weldable material to form the dial, while also necessitating time-consuming manufacturing and assembly operations, including welding the feet and then screwing them into a case.
  • this solution is incompatible with certain watches where the available space is very limited, restricting the number of screws that can be inserted to secure the dial, for example, wristwatches equipped with multiple mechanical functions.
  • the general objective of the invention is to propose a dial solution for watch parts that avoids the drawbacks of the prior art. More specifically, the invention seeks to achieve all or some of the following objectives.
  • a first objective of the invention is to offer a dial solution suitable for any type of material, more particularly for a fragile material, such as a ceramic.
  • a second object of the invention is to offer a dial solution that combines simple manufacturing, user-friendly integration into a timepiece, and compatibility with all timepieces, including wristwatches with a small available volume.
  • a third object of the invention is to propose a dial solution enabling reliable and robust fixing of the dial on a blank or frame of a watch part.
  • the invention is based on a dial plate defined by independent claim 1.
  • the invention is based on a dial 10 illustrated by the figure 1 , obtained by the mechanical assembly of two distinct components, a dial plate 1 and a connecting ring 2.
  • the connecting ring 2 extends under the dial plate 1, in the peripheral part of the dial plate 1, and has the function of forming a removable fixing component of the dial 10 on a blank of a watch part.
  • the horizontal direction is any direction in a plane parallel to a horizontal plane, in particular to the surface of the dial plate 1, which may be flat or substantially flat.
  • the vertical direction z is conventionally defined as the direction perpendicular to a horizontal plane, oriented from the dial plate towards the side intended to be visible to the wearer of a watch incorporating the dial plate.
  • the horizontal direction will be defined from a plane substantially tangent to the upper surface of the dial plate and perpendicular to the vertical direction z.
  • the upper surface of the dial plate will designate the surface visible to the wearer of a wristwatch, and the lower surface of the dial plate the invisible surface, facing inward toward the inside of the watch, on the side of the wrist of the wristwatch wearer.
  • dial to mean any indicator intended to be fixedly mounted within a watch case.
  • a counter for an indication derived from the time can be considered as a dial.
  • the dial plate 1 has a disc shape, comprising a small thickness (also called height, as it is oriented vertically according to the chosen convention) between a first lower flat surface 12 intended to face the inside of a watch and a second upper flat surface 13, opposite and parallel, intended to be visible.
  • This dial plate 1 has a central vertical axis A passing through its center.
  • the first lower surface 12 and/or the second upper surface 13 may be non-planar, but for example curved. It may have a vertex at its center. It may be convex or concave.
  • the dial plate could have a non-circular shape, as will be discussed later.
  • FIG 2 represents a cross-sectional view of the dial plate 1 passing through a vertical median plane, that is to say, a vertical plane comprising the axis A of the dial plate or, more generally, a vertical plane passing through the center of the dial plate 1.
  • This figure 2 This allows us to represent, more specifically, a section of a third surface 11 of the dial plate 1, forming a peripheral contour surface of the dial plate 1.
  • This third surface 11 connects the first lower surface 12 and/or the second upper surface 13. It forms an assembly surface of the dial plate 1, as will be detailed later.
  • This section of the third surface 11 has the particularity of not being oriented along the vertical direction z. In other words, it is not perpendicular or substantially perpendicular to the dial plate 1, and more specifically to either of the first and second surfaces 12, 13.
  • the first part 11a and the second part 11b of the third surface 11 are therefore inclined outwards from the dial plate 1, that is to say in a direction comprising a horizontal component which moves away from the first and second surfaces 12, 13 of the dial plate 1.
  • the first part 11a of the section of the third surface 11 has an inclination of first angle ⁇ 1 relative to the first surface 12 and/or relative to a horizontal plane.
  • This first angle ⁇ 1 is advantageously between 50° and 70°, or even between 60° and 70°.
  • the second part 11b of the third surface 11 has a second inclination angle ⁇ 2 relative to the upper second surface 13 and/or relative to a horizontal plane.
  • This second angle ⁇ 2 is advantageously between 60° and 80°, or even between 65° and 75°.
  • the first angle ⁇ 1 is advantageously smaller than the second angle ⁇ 2.
  • the third part 11c has a vertex, that is, an area furthest from the second upper surface 13. This vertex is approximately positioned in the middle of the thickness of the dial plate 1 or slightly below the horizontal median plane of the dial plate 1. This vertex consists of a point according to the embodiment.
  • the third connecting portion 11c is a rounded section, specifically with a radius between 0.1 mm and 0.5 mm. It connects the two portions 11a and 11b to form a continuous curve. This rounded curve is advantageously smooth.
  • the first part 11a and the second part 11b are inclined linear parts in the embodiment, but could alternatively have other shapes not necessarily linear.
  • the third peripheral contour surface 11 extends around the entire perimeter of the dial plate 1. Alternatively, it could extend along one or more sectors around the perimeter of the dial plate 1.
  • the dial plate is a surface of revolution with axis A. All sections obtained by a vertical median plane, that is, a plane perpendicular to the upper second surface 13 including its axis and/or center, advantageously have the same shape.
  • the dial plate preferably has no discontinuity on its peripheral contour, which has a horizontal section of well-defined geometry, for example, circular, rectangular, polygonal, etc., and particularly without truncation.
  • the dial plate could be not circular, but for example polygonal, square, or rectangular. In all cases, it is advantageous that all or nearly all sections by a vertical median plane have the same shape.
  • the dial plate 1 may be ceramic-based, in particular zirconia or alumina, a fluorescent and/or phosphorescent ceramic, or a composite ceramic based on yttria-treated zirconia and Dy/Eu-doped strontium aluminate. It may advantageously be made of "luminescent zirconia", for example as described in the patent application. EP2730636 Alternatively, it can be made from a composite material. Alternatively, it can be made from a stone, such as onyx, opal, turquoise, or sapphire, or from Mother-of-pearl. By the expression “made from a certain material” we mean that the dial plate comprises at least 50% by weight, or even at least 80% by weight, of said material.
  • the dial plate 1 can be coated with a layer of varnish, for example a varnish with fluorescent and/or phosphorescent properties, so as to modulate the day and night appearance of the dial plate.
  • the dial 10 can include a second solid plate with fluorescent and/or phosphorescent properties fixed beneath the first lower surface 12 of the dial plate 1.
  • the dial 10 further includes a connecting ring 2, more particularly represented by the figures 3 And 7
  • This connecting ring 2 is intended for assembly with the dial plate 1 described previously. Its function is to assemble the dial 10 onto a watch movement blank or other watch component, as will be detailed later.
  • the connecting ring 2 is preferably made of metal or a metal alloy. It can be made of brass or steel, particularly Nivaflex® .
  • the connecting ring 2 includes a connecting portion 21 in its upper part, having a connecting surface 210 for cooperating with the third peripheral contour surface 11 of the dial plate 1.
  • the connecting portion 21 is therefore intended for securing the dial plate 1.
  • the connecting surface 210 has a frustoconical shape and is suitable for elastic deformation.
  • the connecting portion 21 could have another shape suitable for elastic deformation.
  • the connecting portion includes at least one section passing through a vertical plane having an inclination with respect to the vertical direction, such that its upper end is offset towards the dial plate 1 or towards the center of the connecting ring relative to a vertical direction.
  • the connecting section is inclined towards the center of the connecting ring relative to a direction perpendicular to the plane of the connecting ring.
  • this connecting section 21 serves to hold a dial plate in its assembled position. At least a portion of its contact surface 210 therefore remains in direct or indirect contact with the dial plate in its assembled position, to exert a holding force on this dial plate.
  • this holding is preferably reversible, and this connecting section therefore contributes to a removable holding of the dial plate.
  • the connecting section is adapted to bear against the peripheral contour of a dial plate. By such bearing, it is capable of exerting a force comprising at least one component oriented towards the center of the dial plate, particularly a radial component in the case of a circular dial plate.
  • the connecting portion 21 further includes a horizontal or substantially horizontal support surface 211 intended to receive the support of a lateral part, or peripheral part, of the first lower surface 12 of the dial plate 1.
  • the connecting ring 2 further includes a lower fixing portion, which extends below the connecting portion 21, and which is intended for fixing the connecting ring 2 to a watch blank, and thus for fixing a dial within a watch.
  • this lower fixing portion has the form of a skirt 22 which extends substantially in a direction opposite to the connecting surface 210, relative to the support surface 211.
  • the connecting portion 21 and the lower fixing portion form portions arranged substantially in the vertical direction, which are distributed across and on the other side of the horizontal or substantially horizontal support surface 211.
  • the skirt 22 of the embodiment extends in a vertical direction. It comprises at least one elastic element 220. Preferably, this elastic element 220 extends partially along the height h of the skirt 22.
  • the elastic element 220 advantageously takes the form of a blade embedded in the wall of the skirt 22. It may, for example, take the form of a blade embedded at both ends. Such a blade may extend in a substantially horizontal direction. It may be formed by at least one through slot 221, or cutout, extending in a horizontal plane and formed in the wall of the skirt 22.
  • the skirt 22 comprises several elastic elements. According to the embodiment, the skirt 22 comprises three identical elastic elements 220, 220', 220". These three elements are advantageously equally distributed around the circumference of the connecting ring 2.
  • the portion for attaching the connecting ring i.e. the skirt 22 in the embodiment, has a shape designed to cooperate with a blank of a watch part, as will be detailed later with reference to the figure 7
  • This design therefore includes the shape and additional elements for the connecting ring's fixing portion to enable the fastening function.
  • This fixing is removable. Depending on the embodiment, this fixing can be done without tools. It is of the clip-on or spring-fit type.
  • THE figures 4 to 6 They illustrate more precisely the assembly of a dial plate 1 with a connecting ring 2.
  • the assembly is carried out by pressing or clipping, that is to say, by elastic interlocking. This assembly is therefore carried out without necessarily requiring tools. It does not It also does not require any tedious operations such as welding or gluing. Furthermore, it can be reversible and removable.
  • FIG 4 illustrates an approach phase of the dial plate 1 above the connecting portion 21 of the connecting ring 2.
  • the first part 11a of the cross-section of the third surface 11 of the dial plate 1 comes to rest on the upper end of the connecting surface 210 of the connecting ring 2.
  • the dimensions of the frustoconical connecting surface 210 are such that the downward pressure exerted on the dial plate 1 then induces a progressive elastic deformation of the connecting portion 21 of the connecting ring 2 with which the third surface 11 cooperates.
  • the third surface 11 of the dial plate 1 therefore cooperates with the connecting surface 210 by contact.
  • the connecting portion 21, which is inclined on the side of the dial plate with respect to a vertical direction in its rest position is therefore moved away in the direction of the vertical by the contact of its connecting surface 210 with the dial plate 1.
  • the assembly movement continues until the first lower surface 12 of the dial plate 1 comes to rest against the support surface 211 of the connecting ring 2, as shown in the figure 5
  • the connecting surface 210 of the connecting ring 2 Due to the deformation of the connecting portion 21, the latter exerts a holding force on the dial plate 1, ensuring its reliable and robust retention.
  • the connecting surface 210 of the connecting portion 21 of the connecting ring 2 has the advantageous characteristic of directing the holding force downwards, that is, of exerting a force that tends to press the lower first surface 12 of the dial plate 1 against the support surface 211 of the connecting ring 2. It thus opposes the withdrawal of the plate. dial 1 and promotes its stable retention.
  • the connecting surface 210 therefore remains in contact with the dial plate 1 to ensure its retention. Furthermore, the connecting portion 21 remains in a deformed position in the final configuration, so that it exerts an elastic restoring force on the dial plate, thus fulfilling the retaining function.
  • this restoring force includes at least one component directed towards the center of the dial plate.
  • the stresses exerted by this holding force are concentrated on portion 11c, which advantageously minimizes stresses within the dial plate material while ensuring adequate holding force of the dial plate on the ring.
  • the contact area of the third surface 11 is effectively reduced to a single point, which is the aforementioned vertex of the third portion 11c. Consequently, the contact between the third surface 11 and the connecting surface 210 is linear or substantially linear.
  • FIG. 6 illustrates a phase of dissociation of the dial plate 1 from the connecting ring 2.
  • the dial plate 1 is pivoted, for example, by levering a specific area of the dial plate 1.
  • the aforementioned linear or substantially linear contact between the third surface 11 of the dial plate 1 and the connecting surface 210 of the connecting ring 2 facilitates this disassembly of the dial plate 1 by defining an advantageous pivoting area P of the dial plate 1 at the level of its third portion 11c of its third surface 11, which pivots against the connecting surface 210 of the connecting portion 21 of the connecting ring 2.
  • the latter deforms elastically during this operation.
  • the solution according to the embodiment also allows the disassembly of the dial plate 1 from the connecting ring 2, which is This is particularly advantageous in the context of potential after-sales service, for example, if it becomes necessary to replace the connecting ring 2 or the dial plate 1.
  • the dial plate 1 and the connecting ring 2 therefore remain two separate components that can be removably assembled, according to the embodiment.
  • the third surface 11 of the dial plate 1 is an outer peripheral surface of the dial plate 1.
  • the vertex of the third part 11c belongs to a circle centered on the axis A, whose radius R, visible on the figure 2 , defines the largest radius of the dial plate 1.
  • dial plate 1 has the advantage of being able to be made of a fragile material, in particular a material that does not exhibit plastic deformation under stress, as has been specified.
  • FIG. 7 This illustrates more specifically a fixing phase of the dial 10, and more precisely of the connecting ring 2, according to the embodiment on a blank 3 of a timepiece.
  • the dial 10 is in an approach phase over a blank.
  • This blank 3 includes protrusions 31, shaped to cooperate with the elastic elements 220, 220', 220" of the connecting ring 2.
  • each blade 220 is pushed apart by a protrusion 31, deforming elastically. This movement is continued until the first lower surface 12 of the dial plate 1 comes to rest on the blank 3.
  • the skirt 22 of the connecting ring 2 also includes a vertically or substantially vertically oriented surface 222, which is designed to abut against a surface 33 of the blank 3, also oriented vertically or substantially vertically. These elements serve to ensure angular indexing of the dial on the blank.
  • the connecting ring 2 can directly cooperate with a case 4 or any component of a timepiece, so as to allow the angular positioning of the dial 10 within a timepiece.
  • the connecting ring 2 in this embodiment also has the advantage of allowing the dial 10 to be mounted on a watch movement without requiring assembly screws or feet, for which spaces would need to be provided within the watch movement. It thus remains compatible with the integration of a dial within a watch movement that leaves little free space for dial positioning.
  • THE figure 8 This illustrates the final positioning of a dial according to the embodiment of the invention within a timepiece.
  • the connecting ring 2 is fixed to a blank 3 of the watch movement 30, as described previously.
  • the lower first surface 12 of the dial plate 1 bears against the support surface 211 of the connecting ring 2 on its periphery, and against an upper surface 32 of the blank 3 in the central part of its surface.
  • it could be positioned against any other stop arranged to prevent the vertical movement of the dial 10 towards the interior of the timepiece.
  • the connecting ring 2 includes one or more specific surfaces designed to cooperate with a case 4 of a watch case 40 of the timepiece, to allow the axial play of the dial 10 to be delimited, and in particular to mitigate the effect of possible shocks.
  • the connecting ring 2 may include a horizontal or substantially horizontal surface 212 arranged at the upper end of its connecting portion 21, which is positioned against a horizontal or substantially horizontal surface 410 of the case 4. Note that this stop or support may intentionally have some play.
  • the horizontal surface 212 of the connecting ring 2 is concealed by a flange 41 of the case 4, the corresponding horizontal surface 410 of which is formed beneath the flange 41.
  • the connecting ring 2 includes a vertical or substantially vertical surface 213, which cooperates with a vertical or substantially vertical surface 411 of the case 4.
  • This cooperation between said two vertical surfaces 213, 411 allows the dial 10 to be guided within the watch case 40. This cooperation is achieved by contact. It can include a set.
  • the dial assembly can thus be carried out directly between the dial 10 and the case 40, independently of the watch movement 30 comprising the blank 3 on which the dial 10 is mounted.
