Definitions

  • the present invention relates to a watch case provided with a rotating bezel mounted on a notch on an annular seat secured to the middle of the case and comprising a positioning device having, on the one hand, a positioning division distributed equiangularly around of the axis of rotation of the rotating bezel, formed on a face situated in a plane perpendicular to this axis and, on the other hand, at least one elastic locking member armed between this face and an opposite face, one elements, positioning division or elastic latching member being angularly integral with the rotating bezel and the other, with the middle part of the case, so that the elastic latching member and said positioning division are angularly movable l relative to each other and that the elastic snap-in member applies said rotating bezel against said annular seat, said elastic snap-in member comprising at least one bending blade, inclined relative to the plane of this rotating bezel and at least a portion of which is located within the range of said positioning division in order to engage therein successively and is oriented tangentially to the average
  • Watch cases provided with rotating bezels comprising an annular toothing of angular positioning cooperating with elastic means integral with the middle to retain the rotating bezel in a determined angular position are known, for example from patents CH-214 225, DE-A1- 32 34 405, CH 03 288/69, CH-B5-631 592 and JP-U-49-3341.
  • the toothing may be of the ratchet type so as to allow rotation of the bezel only in one direction.
  • an annular portion of the rotating bezel has ratchet edge teeth which engage with pawls.
  • the cutting of a toothing on a rotating bezel can only be carried out by milling and individually on each rotating bezel thereby constituting a relatively long and complex operation.
  • the object of the present invention is to remedy, at least in part, the drawbacks arising from the above-mentioned solutions.
  • the subject of this invention is a watch case provided with a rotating bezel according to claim 1.
  • the main advantage of this invention lies in the fact that it makes it possible to use a positioning division obtained by stamping an annular element with a rotating bezel notched on the middle part, this bezel being applied elastically against the annular seat of the middle by the same snap-in spring member as that cooperating with the positioning division.
  • This solution simplifies both manufacturing and mounting the rotating bezel, while ensuring centering and braking of this telescope against a fixed annular seat ensuring perfect centering precision.
  • Figure 1 is a partial sectional view of this embodiment.
  • FIG. 2 is a partial plan view of a detail of FIG. 1.
  • Figure 3 is a plan view of another detail of Figure 1.
  • FIG. 4 is an elevation view along line IV-IV of a detail in FIG. 3.
  • Figure 5 is a view similar to Figure 4 of a variant.
  • FIG. 6 is a sectional view of a variant of FIG. 1.
  • FIG. 7 is a partial plan view of a detail of FIG. 2.
  • FIG. 8 is a sectional view of another variant of FIG. 1.
  • FIG. 9 is a sectional view of a last variant of FIG. 1.
  • Figure 1 illustrates a part of the watch case fitted with a rotating bezel.
  • the middle part 1 which has a cylindrical face 2 against which a ring 3 of plastic material for mounting a glass 4, is clamped by a metal ring 5 of L-section which is applied against the upper face 6 of the middle 1.
  • This ring 5 has an external frustoconical face 7 on which is mounted a notch a rotating bezel 8, having an internal frustoconical surface 9 of the same diameter and the same angle as the frustoconical face 7.
  • the ring 5 comprises plus an annular clearance 10, formed in the upper face of the flat part of its section, the internal edge of which has three millings 11 illustrated in FIG. 3.
  • a spring ring 12 the internal edge of which comprises three radial projections 13, is arranged in this annular clearance 10 and is made angularly integral with the ring 5 by engagement of the radial projections 13 in the millings 11.
  • the spring ring 12 is wavy relative to its plane and the tops of the corrugations are cut over half the width of the spring ring and over a portion of its circumference to release three blades 14 forming ratchet as we will see later.
  • Figure 1 shows that this spring ring 12 rests on the one hand against the bottom of the annular clearance 10 and, on the other hand, against an annular element 15 secured to the rotating bezel 8. Therefore, the two faces frustoconical 7 and 9 are applied elastically against each other, simultaneously causing the centering and braking of this bezel 8. To rotate it, it is therefore necessary to exert an axial pressure in the direction of the middle part 1 thus separating the conical surfaces 7 and 9 to each other.
  • the internal edge of the annular element 15 is cut by a groove 16 with radial faces perpendicular to the plane of rotation of the bezel, constituting a division of angular positioning of this rotating bezel.
  • a groove 16 with radial faces perpendicular to the plane of rotation of the bezel, constituting a division of angular positioning of this rotating bezel.
  • the free end of the blade 14 penetrates into the divisions formed by the groove 16.
  • the leaf spring 14 is inclined relative to the plane of the annular element 15, its end free form, with the radial flank 16a adjacent to it, an acute angle opening downwards.
  • the telescope 8 has a second frustoconical annular surface 17, adjacent to the upper face of the annular element 15, used for fixing a second annular element 18, the upper face of which carries a reading scale intended to cooperate with the watch indicator hands (not shown).
  • FIG. 1 also shows that the spring ring 12 is reinforced by compression of its undulations between the bottom of the annular housing 10 and the underside of the annular element 15, so that in addition to its latching function, this spring ring 12 is used to apply the frustoconical face 9 of the rotating bezel 8 against the frustoconical face 7 of the ring 5 thus ensuring its centering.
  • the rotating bezel 8 When the rotating bezel 8 is actuated, the user exerts a slight axial pressure on it which, by compressing the spring ring 12, separates the frustoconical surfaces 7 and 9 from one another and allows the rotation of the telescope in the direction authorized by the ratchet blades 14.
  • the telescope must be able to turn in two opposite directions: a ratchet blade 14 ′ is then used, with a bent end, such as that illustrated in FIG. 5.
  • FIG. 6 shows a rotating bezel 8 in which the second annular element 18 is fixed in the annular notch 17 of this bezel by means of an electrically insulating lining 19, in this example a polyurethane lining of the type Macrolon R intended to avoid any corrosion by the establishment of an electron current between metals of different electro-chemical potentials.
  • the angular positioning division is no longer obtained by cutting a groove 16, as illustrated in FIGS. 1 and 2, but by rectangular openings 16 ′ passing through the annular element 15 of the 8 ′ telescope.
  • These rectangular openings 16 ′ can cooperate as well with the right ratchet blade 14 such as that of FIG. 4, ensuring a determined angular position of the telescope and its uni-directional rotation, than with the ratchet blade 14 ′ with angled end, allowing bi-directional rotation in addition to the angular positioning.
  • the positioning division 16 or 16 ′ is obtained by stamping, it is possible to replace the notch fixing of the annular element 18 by riveting by gluing the annular element 18 ′ illustrated by FIG. 8 on the packing insulator 19 ′ provided with feet 20 for example five in number, coming from molding with the lining 19 ′ and introduced into cutouts 22 passing through the annular element 15 ′ of this bezel 8 ′ and riveted to the reverse of this annular element 15 ′ .
  • the feet 20 could also be made of metal, either directly out of the material forming the annular element 18 ′ or by bringing them thereon.
  • the metal base could be surrounded by a tube of insulating material to avoid electrical contact between the metal forming the rotating bezel and that of the annular element 18 ′.
  • the positioning division of the rotating bezel is no longer provided on the latter, but is formed by rectangular openings 16 ⁇ passing through the horizontal portion of the ring 5 ⁇ .
  • the rotating bezel 8 ⁇ could then be produced in one piece, although for aesthetic considerations in particular, it will be preferred to manufacture it in two pieces.
  • the spring ring 12 ⁇ is then fixed angularly on the rotating bezel 8 ⁇ by a lug 21 cut and folded, engaged in an opening 23 cut in the annular element 15 ⁇ , the positioning division 16 ⁇ being fixed.
