Definitions

  • the present invention relates to a wristwatch box.
  • the wristwatch boxes generally include, inter alia, a middle part interposed between a bezel and a bottom and protruding members, such as horns or hinges, for attachment to a bracelet.
  • the protruding fasteners to the bracelet are generally defined by the middle part. This limits the number of possible materials for said middle. Indeed, it must be made in a material that can be easily machined to produce the shape of the fasteners.
  • the shape and dimensions of the caseband are furthermore necessarily dependent on those of the fasteners.
  • the presence of these fasteners can make some parts of the case difficult to access for finishing operations such as polishing, satin finishing, sanding, etc.
  • a wristwatch box comprising a middle-bezel, a bottom and hinges for attachment to a bracelet, wherein the hinges are defined in part by the middle-bezel and partly by the bottom.
  • the hinge portions defined by the middle-bezel and those defined by the bottom are resiliently assembled by retaining members.
  • a disadvantage of this box is that the hinges are not robust. The risk is indeed high that the parts of hinge defined by the middle-bezel and those defined by the bottom separate under the effect of tensile forces or shocks.
  • the present invention aims to provide a wristwatch boot that allows great freedom in the realization of the middle without harming the robustness of the fasteners to the bracelet.
  • a wristwatch box according to claim 1 attached, that is to say a wristwatch box comprising an upper element, a lower element, a middle part between the upper and lower elements. lower and protruding members for attaching to a bracelet, the first parts of these protruding fasteners being defined by the upper member and second portions of these projecting fasteners being defined by the lower member, said first and second parts respectively comprising first and second retaining members which cooperate to assemble said first and second parts, characterized in that the upper and lower elements are arranged for, when assembling the box, to be able to rotate relative to the other around the axis of the box a position where the first and second retainers do not cooperate at a position where they cooperate.
  • a wristwatch box comprises a middle part 1 interposed between an upper strapping 2 and a lower strapping 3, a bezel in two parts 4, 5 disposed on the middle part 1 and on the upper strapping 2, an ice-cream 6 mounted in the bezel 4, 5 and a bottom 7 mounted in the lower strapping 3.
  • the two parts of the bezel are respectively an inner metal part 4 and an outer part 5 which is preferably in another material, for example ceramic, glued on the inner part 4.
  • the bottom 7 is for example an ice, as shown.
  • the middle 1 rests on the lower strapping 3 and surrounds an inner rim 8 thereof.
  • the caseband 1 comprises an annular projection 9 which defines radial bosses 10.
  • the upper band 2 rests on the outer part of the upper face of the caseband 1, around the annular projection 9, and comprises notches 11 which receive the bosses 10.
  • the bezel 4, 5 rests partly on the annular projection 9 and partly on the upper strapping 2. Seals 12 to 15 between the glass 6 and the bezel 4, 5, between the bezel 4, 5 and the middle part 1, between the middle 1 and the lower strapping 3 and between the lower strapping 3 and the bottom 7 seal the box.
  • the fastening members of the bracelet are not defined by the middle part 1, but partly by the upper strapping 2 and partly by the lower strapping 3.
  • these fasteners are in the form of two pairs of horns 16 whose parts defined by the lower band 3, designated by the mark 17, comprise orifices 18 intended to receive the ends of bracelet bars and whose parts defined by the upper band 2, designated by the reference mark 19, cover the upper part of parts 17.
  • the horn portions 19 defined by the upper strapping 2 each comprise at their distal end a hook 20 oriented towards the inside of the boot and in a plane perpendicular to the axis A of the box.
  • This hook 20 cooperates with a notch 21 formed in the outer face of the corresponding horn portion 17 defined by the lower strapping 3 to assemble the horn portions 17, 19.
  • This hook 20 and this notch 21 constitute retaining members which prevent the horn parts 17, 19 to separate from each other in the direction of the axis A of the box by deformation under the effect of a shock, for example, and which limit the deformation of the part horn 17 under the effect of a tensile force exerted by the bracelet.
  • the horn parts 19, with their hooks 20, thus provide rigidity to the horn parts 17 to which the bracelet is attached.
  • the horn portions 19 defined by the upper strapping 2 each further comprise a surface 20a (cf. figure 3 ) located in a plane perpendicular to the axis A and which rests on a surface 21a of the horn portions 17. it also lies in a plane perpendicular to the axis A.
  • These bearing surfaces 20a, 21a contribute to the robustness of the horns 16. They also allow the horn parts 17, 19 to meet with a continuity of shape and thus give the horns 16 a harmonious appearance.
  • the box is held in a state assembled by first screws 22 (cf. figure 4 ) each passing through respective holes communicating the lower ring 3, the middle part 1 and the inner part 4 of the bezel, parallel to the axis A.
  • the head of these screws 22 bears on a shoulder defined by the drilling lower strapping 3.
  • the threaded end of these screws 22 cooperates with a tapping of the bore of the inner part 4 of the telescope.
  • These screws 22 tighten the straps 2, 3, the middle part 1 and the bezel 4, 5 between them in the direction of the axis A and angularly position the lower strapping 3, the middle part 1 and the bezel 4, 5 relative to each other. to others.
  • the upper strapping 2 is positioned angularly relative to the other elements of the box by its notches 11 which cooperate with the bosses 10.
  • second screws 23 are also provided which each pass through respective holes communicating a horn portion 17 defined by the lower strapping 3 and the corresponding horn portion 19 defined by the upper strapping 2. These second screws 23 help to maintaining the parts of horns 17, 19 firmly fixed to each other, in addition to the cooperation between the hooks 20 and the notches 21. Thanks to the cooperation between the hooks 20 and the notches 21, these second screws 23 undergo few constraints during efforts exerted on the horn parts 17, 19. These second screws 23 are nevertheless not essential and could therefore, in a variant, be removed.
  • the upper and lower straps 2, 3 are typically made of metal.
  • the middle 1, it can be made in other materials. In particular, since it does not include the horns 16, the middle part 1 can be made in difficultly machinable materials such as composite materials with carbon fiber reinforcement and epoxy resin matrix or sapphire. Note further that the absence of horns on the middle 1 makes easily accessible the entire surface of the caseband 1 for finishing work of the type polishing, satin or sandblasting, for example.
  • the straps 2, 3 are arranged to be rotatable relative to each other about the axis A during assembly of the boot, before the first and second screws 22, 23 have been introduced.
  • the assembly of the box is carried out initially by applying the strapping 2, 3 on either side of the caseband 1 (not shown in FIG. figure 6 for reasons of clarity) in respective different angular positions which are such that the hooks 20 are outside the notches 21.
  • the strings 2, 3 are rotated relative to each other about the axis A to bring the hooks 20 into the notches 21, the horn parts 17, 19 then forming together the horns 16 of the box ( figure 7 ).
  • the middle part 1 is integral with the strapping upper 2 because of the cooperation between the notches 11 and bosses 10 and is guided in its rotation relative to the lower strapping 3 by the inner rim 8. Then, the bezel 4, 5 is applied to the middle 1 and the upper strapping 2 and fixed all by means of the screws 22, 23.
  • the horn parts 17, 19 can be robust. A slight clearance can be provided between the hooks 20 and the walls of the notches 21 to allow the hooks 20 to be placed in the notches 21 without being stressed.
  • provision can be made for the introduction of the hooks 20 in the notches 21 by the relative rotation of the straps 2, 3 to cause a slight elastic deformation of the horn parts 17, 19 and a slight tightening of the hooks 20 against a wall of the Notches 21.
  • the surfaces of the horn portions 17, 19 which may be in contact during the rotation of the straps 2, 3 with respect to each other are parts of surfaces of revolution about the axis A.
  • These surfaces in particular, for the horn parts 19, the internal surfaces designated by the reference 24 (cf. figures 3 and 6 ), in particular the end surface of the hook 20, and for the horn parts 17, the outer surfaces designated by the reference 25, in particular the bottom surface of the notches 21. All these surfaces can be obtained by a shooting. With these surfaces of revolution 24, 25, the radial clearance between the straps 2, 3 can be low and the adjustment can be accurate.
  • the horn portions 17 defined by the lower strapping 3 could cover the horn portions 19 defined by the upper strapping 2.
  • the receiving orifices 18 of the bracelet straps would be formed in the parts of the straps. horn 19.
  • the box and in particular the caseband 1 may have various forms other than circular.
  • the upper and lower strapping 2, 3 will be replaced by shaped elements adapted to the box but fulfilling the functions described above.
