Definitions

  • the invention relates to a wristwatch case as well as such a wristwatch provided with this case.
  • a bracelet it is known in the field of watchmaking to fix a bracelet to the middle part of a watch case from a spring bar.
  • a strip conventionally comprises a fixing pin at each of its ends.
  • the first pin is mounted integral with a sliding piston in a tubular part and the second pin is itself arranged in the other tubular part of this bar.
  • the piston generally comprises a helical spring arranged in the tubular part in order to cause the first pin to protrude out of the tubular housing.
  • the object of the invention is to overcome at least one of the drawbacks of the aforementioned state of the art. More specifically, one of the goals of the invention is to be able to mount/assemble lugs, in particular made of plastic, on a metal watch case, without welding and/or without gluing and/or without clipping.
  • Another object is to simplify the operations of fitting or even replacing a strap of a watch.
  • the invention also relates to a wristwatch comprising such a case.
  • the lugs form a one-piece element with the bracelet.
  • each aspect of the invention is combinable with the other aspects.
  • the aspects of the invention are also combinable with the embodiments of the description, which in addition are combinable with each other.
  • the figure 1 represents a watch 1 provided with a watch case 2.
  • This watch case 2 is in particular included in a wristwatch 1
  • Such a case 2 comprises in particular a middle part 4, a back 20, two lugs 6, a watch movement provided with a display module comprising for example a dial 36 and hands 35.
  • the case 2 and in particular the middle part 4 has a transverse plane P substantially perpendicular or strictly perpendicular to the longitudinal direction of the bracelet 24.
  • this transverse plane P is substantially parallel or strictly parallel to a central axis A of the case 2 or even comprises this central axis A.
  • This central axis A passes through this case 2 at its center O and coincides with an axis of rotation B of at least one of the hands 35 of the watch 1.
  • Such a central axis A is substantially perpendicular or strictly perpendicular to the longitudinal direction of the strap 24.
  • Such a central axis A is substantially perpendicular or strictly perpendicular to the dial 36 and/or to the bottom 20 of the case r 2 in particular to an outer face and/or an inner face of this bottom 20.
  • This transverse plane P visible on the figure 2 is a plane of symmetry of the middle part 4 and therefore of the case 2.
  • the two lugs 6 are arranged symmetrically with respect to the transverse plane P while being opposite to each other when they are mounted on the case 2 and therefore on the case middle of this case 2.
  • these two horns 6 are each an orthogonal symmetry of each other with respect to this transverse plane P.
  • These two horns 6 are provided to ensure the complete fixing of the bracelet 24 to the middle part 4. These horns 6 are intended to be fixed to different ends of the bracelet 24. More precisely, the first horn 6 is intended to be fixed to a first end of the bracelet 24 and the second horn at a second end of the bracelet 24. When the bracelet 24 comprises two strands, the first horn 6 is fixed to the first strand and the second horn 6 to the second strand.
  • Such a configuration is also a specificity of the invention which makes it possible to have a box 2 comprising only two horns 6 and not four horns as is conventionally the case in the state of the art. Such a configuration participates in particular in simplifying the operations of assembly and disassembly of the bracelet 24 on the case 2.
  • the caseband 4 preferably has a substantially cylindrical shape.
  • This middle part 4 comprises a peripheral wall 10 comprising two attachment zones 12 each provided with a support portion 3, said zones 12 being arranged on either side of the transverse plane P.
  • These first and second zones 12 are preferably arranged on the peripheral wall 10, symmetrically and this, being diametrically opposed to each other.
  • Such first and second attachment zones 12 are specifically provided to receive the first and second horns 6 of this case 2 of watch 1.
  • These attachment zones 12 which are visible on the picture 2 , have an essentially cylindrical arc shape, a shape which is likely to be taken on by the lugs 6.
  • the support portion 3 is configured to cap part of a face upper 32 of the horn 6 resting on this said portion 3 when the said horn 6 is mounted on the case 2.
  • the support portions 3 of the said zones 12 are each defined in the peripheral wall 10 close to or even in an edge of the middle part 4 connecting an upper part of this middle part 4 capable of receiving a crystal from the case 2, to this peripheral wall 10.
  • the lower part 25 of this middle part 4 is provided to receive the bottom of the case 2.
  • each groove 14 and said at least one rib 16 can each have a random shape.
  • each groove 14 of the attachment zone 12 is engraved/sculpted/drawn in the peripheral wall of the middle part of the case 2.
  • this fixing device can also comprise in a complementary manner the bottom 20 and a blocking element 8 which we will describe below. Such a device thus makes it possible to carry out a removable fixing of the horns 6 on the middle part 4 of the case 2.
  • the attachment zones 12 may each comprise, by way of example: at least one pair of grooves 14 or at least one triplet of grooves 14 or even at least one quadruplet of grooves 14.
  • the first and second attachment zones 12 each comprise two triplets of grooves 14 or even three pairs of grooves 14, i.e. six grooves 14.
  • caseband 4 logically comprises twelve grooves formed on its wall 10.
  • the six grooves 14 i.e. the two triplets of grooves 14 or even the three pairs of grooves 14 located on the first attachment zone 12 are arranged opposite of the transverse plane P in a substantially symmetrical or symmetrical manner with respect to the six other grooves located on the second fixing zone 12.
  • the grooves 14 of the first triplet and of the second triplet of grooves 14 can be arranged symmetrically on either side of a plane orthogonal to the transverse plane P with the first triplet on one side of this orthogonal plane and the second on the other e side of this plane.
  • the grooves 14 of the three pairs of grooves 14 are distributed symmetrically with respect to such a plane orthogonal to the transverse plane P with three grooves 14 arranged on each side of this orthogonal plane. It will be noted that this plane orthogonal to the transverse plane P is parallel to the longitudinal direction of the bracelet 24.
  • each groove 14 is closed at one end by a support portion 33 and open at another end at the level of a lower part 25 of the middle part 4. It will be noted that this support portion 33 forms the bottom of groove 14.
  • the first and second horns 6 each comprise at least one pair of ribs 16 or even at least a triplet of ribs 16.
  • these first and second horns 6 each comprise two triplets of ribs 16 or even three pairs of ribs 16 or six ribs 16.
  • each horn 6 is provided with as many ribs 16 as each fixing zone 12 comprises grooves 14
  • the first and second lugs 6 comprise a number of ribs 16 similar to the number of grooves 14 arranged on the first and second attachment zones 12 of the middle part 4.
  • each horn 6 comprises a pair of ribs 16
  • each of these ribs 16 is arranged on the inner wall 17 of the horn 6 in order to slide in the groove 14 of the pair included on the corresponding fixing zone 12.
  • Such a lug 6 has an elongated arc shape making it possible to match that of the attachment zone 12 of the middle part 4.
  • Each rib 16 of each horn 6 each comprise two parts, an upper part 26 called “full” and a lower part 22 called “recessed”. This recessed part 22 is in particular provided to cooperate directly or indirectly with the bottom 20 of the case 2. In this configuration, the bottom 20 can thus participate directly or indirectly in the blocking in translation according to the sliding direction D of the horns 6 on the caseband 4.
  • Each rib 16 comprises at least one clamping element 27 capable of cooperating with an internal face of the groove 14 in which said rib 16 is capable of being arranged by sliding. Said at least one clamping element 27 makes it possible to ensure an axial holding of this rib 16 in the groove 14 and/or a holding of this rib 16 in the groove 14.
  • said at least one clamping element 27 participates in eliminating any play between this rib 16 and this groove 14.
  • a clamping element 27 protrudes from a peripheral wall of each rib 16. More precisely, this clamping element 27 is arranged on this peripheral wall of the rib 16 in particular on the portion of this wall which is located in the upper part 26 of this rib 16.
  • the rib 16 comprises three clamping elements 27. As for example, this clamping element 27 may have the shape of a prism.
  • the upper part 26 of this rib 16 comprises at its free end a support zone 34 capable of resting on the support portion 33 of the corresponding groove 14.
  • the case 2 comprises a zone 21 for mounting the back 20 on the middle part 4 of this case 2.
  • This mounting zone 21 comprises in particular an annular cavity 18 or annular groove 18 provided to receive the back 20 of the case and the blocking 8 of this bottom 20 to the middle part 4.
  • This cavity 18 comprises a bottom 29 and first and second peripheral walls 28a, 28b.
  • the first and second peripheral walls 28a, 28b are preferably substantially opposed or strictly opposed to each other.
  • This second wall 28b and this bottom 29 of the annular cavity 18 are both formed both by the lower part 25 of the middle part 4 and by the recessed part 22 of each rib 16 when the latter is slid into the corresponding groove 14.
  • This cavity 18 is adapted to receive the blocking element 8 as well as a fixing part 30 integral with the body of the bottom 20 of the watch case.
  • this fixing part 30 protrudes from an inner face of this bottom 20 of the case and this, extending in a direction oriented towards the bottom 29 of the annular cavity 18.
  • this part fixing 30 also extends on the inner face of the bottom equidistant from the edge of this bottom 20 of the case.
  • this fixing part 30 is specifically provided/configured to be arranged in the annular cavity 18.
  • This fixing part 30 can be formed of a single element or of several elements.
  • the first peripheral wall 28a comprises a recess 31 provided for the arrangement of a part of the body of the blocking element 8 in this first wall 28a.
  • This recess 31 may have a section having the shape of the letter "L".
  • this fixing part 30 is then capable of cooperating mechanically with the recessed parts 22 of the ribs 16 in order to ensure the locking in translation of the ribs 16 in the corresponding grooves 14, thus preventing these ribs 16 from slipping and/or coming out of these grooves 14.
  • the back 20 which is fixed at the level of the assembly zone 21 participates in the blocking in translation directly according to the direction of sliding D of the horns 6 on the middle part 4.
  • the blocking element 8 which is visible on the figure 6 , can be a ring or a shaped seal or even an O-ring which can participate in the sealing of the case 2 as well as in the blocking/fixing of the back 20 on the middle part 4.
  • each rib 16 and in particular the recessed part 22 of the latter is capable of coming into contact with an abutment surface defined in a localized portion of the fixing part 30.
  • this fixing part 30 comprises a portion defining the abutment surface which is associated with each of the ribs 16.
  • each rib 16 extends substantially perpendicular or perpendicular to this blocking element 8 and therefore to the bottom of the case 2.
  • each of these horns 6 is blocked in translation in the direction D of sliding on the caseband 4 by the back 20 and by the support portions 33 of the grooves 14.
  • the support portions of the zones 12 can also participate in this blockage in translation.
  • the lugs 6 each comprise an attachment zone 23 of a strap strand 24.
  • the horns 6 can form with the bracelet a one-piece element of the watch, that is to say a single and unique part of this watch.
  • the caseband 4 can be made with a first material and the two lugs 6 with a second material, the first material preferably being different from the second.
  • the materials chosen for the middle part 4 and the lugs 6 can be the same.
  • the first and/or the second material can be stainless steel (usually 316L steel), gold, platinum, titanium, brass, ceramic, plastic, carbon, wood, plastic. silver, another metal, a metal alloy, or any combination thereof.
  • the caseband 4 and the lugs 6 may respectively have (at least) coating layers.
  • the material of the caseband 4 may be different from that of the material of the two horns 6, in order to optimize manufacturing costs and/or or to optimize the resistance of the case 2 of the watch.
  • Each layer can be a metallic layer, a varnish or a pigmented layer, or any combination thereof.
  • the invention also relates to a wristwatch 1 comprising a watch case 2 comprising the characteristics of this case 2 presented above.
