Definitions

  • the invention relates to a dial comprising brilliants, appliques or other added elements and more particularly a clock face comprising such decorative elements having a base surface plane.
  • the invention also relates to a method of fixing decorative elements. reported on a dial.
  • a first technique for manufacturing these dials is to fix decorative elements, usually cut stones, between two rings each presenting a seat, and driving the assembly thus formed into a drilling the dial.
  • Such a technique is for example described in the document CH 260 123.
  • This technique however has the drawback of having to make and handle many very small parts, which requires a skilled workforce and leads to cost prices high.
  • Another classic technique for fixing decorative elements with a flat base surface consists of gluing, using an adhesive liquid or semi-liquid, the decorative elements by their base surface in countersinks in the thickness of the dial in places predetermined. This technique although less expensive than the previous one has many drawbacks, however.
  • JP09119986 describes a method of crimping a luminescent element in a housing having a layer of adhesive material on its bottom.
  • a first drawback is that the bonding of the elements decorative is difficult to achieve automatically due to the low dimensions of the decorative elements in question.
  • the brilliant commonly used to form time signs exhibit diameters of the order of 2 mm. Bonding operations for each element decorative, between one and twelve per dial depending on the case, must be made manually, which significantly increases manufacturing costs of these dials.
  • a second drawback is that it is difficult to dose precisely how much glue to deposit in each recess to achieve a satisfactory bonding, that is to say a bonding during which the amount of glue deposited is neither too large, which would risk to cause an overflow on the useful face of the dial when setting place of the decorative element, or insufficient, which could cause a separation during subsequent use.
  • the main object of the invention is therefore to provide a dial, such as a clock face, including decorative elements which are either simple and inexpensive to manufacture.
  • the invention also aims to provide a method of fixing decorative elements on a dial, this process allowing a secure fixing decorative elements on the dial while being easily industrializable and simple to implement.
  • the invention relates to a dial, in particular for a coin timepiece, comprising a plate having at least one housing in which is attached a decorative element or the like, characterized in that the housing comprises a bottom formed by an adhesive tape, the adhesive face of said ribbon being in contact with said decorative element.
  • the reference 1 denotes a dial formed by a disc of metal or rigid plastic material comprising a visible front face 2 and an opposite face 4 called rear face. This disc is typically obtained by stamping a plate, using a die and an appropriately shaped punch.
  • Dial 1 according to the invention includes circular housings 6 on the bottom of which are fixed decorative elements 8 appearing on the front face 2.
  • the dial 1 also conventionally includes a hole 10 provided for the passage needles (not shown).
  • the term “decorative element” means a gloss, a wall lamp or any other decorative element that can be attached to a dial and in particular a clock face.
  • the decorative elements 8 have been provided respectively for twelve o'clock, three o'clock, six o'clock and nine o'clock positions to constitute time signs, it stands to reason that these decorative elements could be arranged in any other place on the dial insofar as they do not interfere not with the central hole 10 provided for the passage of the needles.
  • the housings 6 are formed by openings 12 passing right through the thickness of the plate forming the dial 1, these openings 12 each being closed by a bottom 14 formed from a portion of adhesive tape 16 glued to the rear face 4 of the dial 1.
  • the openings 12 have dimensions substantially greater than those of the decorative elements 8, which makes it easier to install the decorative elements in the housings 6.
  • the adhesive side of the tape 16 forming the bottom 14 is in close contact with the base 18 of the element decorative 8, which thus ensures the fixing of this element 8, on the dial 1.
  • the openings typically have a diameter of about 2 mm, the dial has a thickness of about 0.4 mm and the adhesive tape has a thickness of the order of 0.05 mm.
  • the adhesive tape 10 is for example a tape known as Scotch 850 or Scotch 396 trade names sold by the company 3M or under the trade designation Tesa film 4129 sold by the TESA company.
  • the adhesive tape 16 used is common to all of the housings 6 and for this purpose has a width sufficient to form a bottom 14 simultaneously for all the openings 12 of the dial.
  • the ribbon 16 has a width allowing cover at least the whole of the rear face 4 of the dial 1.
  • the adhesive tape 16 can have adhesive material on both sides and thus ensure also keeping the dial 1 in place in the watch case.
  • the decorative element 8 is presented under the shape of a rectangular gloss housed in a housing 6 of shape corresponding.
  • the gloss 8 is fixed to the bottom 14 by means of a ribbon adhesive 16 glued to the back of the dial.
  • the decorative element 8 is in the form of a stick with a T-shaped cross section, the upper part 8a extends beyond the periphery of the opening 12 in which is housed the lower part 8b.
  • This lower part 8b comprises a flat bottom 18 which comes into close contact with the adhesive face of the tape adhesive 16 bonded to the rear face 4 of the dial 1.
  • the stick 8 is by example made of silver plastic material of ceramic or the like and advantageously forms time signs having an original appearance.
  • This embodiment has the advantage of being able to hide the space free located between the decorative element 8 and the edge of the opening 12 which is normally visible in the case of dials with elements decorative such as brilliants or the like.
  • the plate P ( Figure 6) in which will be stamped a plurality of dials is for example cut from a coil (not shown) and supplied to a conventional stamping station also not shown.
  • Plate P comprises a determined number of dials, typically one half a dozen.
  • the punch and the die are provided for simultaneously form a hole 10 in the stamping of the openings 12 substantially in the center of each dial 1 to allow passage subsequent axes on which the needles of the workpiece will be fixed of watchmaking that the dials are intended to equip.
  • indexing and drive holes 20 for ensuring precise positioning of the plate for subsequent operations as well as perforations for positioning the dial in the watch case. These perforations are typically made at six o'clock on the edge of the dial.
  • dials 2 are cut from the plate P, so that each of these substrates is connected to the rest of the plate by four bridges of material 22.
  • the number and dimensions of the bridges of material 22 vary depending on the shape and the material from which the dial. Typically, the bridges are such that they later allow a easy extraction of dials from the band, for example by a simple pressure on these.
  • re-striping stamped dials i.e. replace the dials 1 in the plate P at the places where they were cut out, the dials 1 being held in the plate P by microwelds which spontaneously create when the stamped part is driven into the place of the P band from which it comes.
  • the adhesive tape 16 is prepared which will subsequently be glued to the rear face 4 of the dials 1.
  • the length and width of the ribbon section 16 correspond to those on plate P.
  • the various elements of the ribbon 16 have been designated in FIG. 7 corresponding to those of plate P by the same reference numeral with the letter r.
