Definitions

  • the present invention relates to a watch case including a middle, a rotating bezel, the first angular positioning marks integral with the middle part, second integral angular positioning marks rotating bezel and elastic means constantly tending to engage said first and second positioning marks with each other.
  • EP 0 686 897 has already proposed a solution to this problem by the use of a positioning spring working with an internal toothing of the rotating bezel.
  • This positioning spring has two segments rights connected by an arcuate segment, the free end of one of the straight segments is held in gear of the telescope by a bearing surface integral with the middle and the free end of the other straight segment is attached to this same stature.
  • the spring is shaped so that the forces exerted by the teeth on its end engaged with the latter, in both directions of rotation of the rotating bezel, serve to increase, respectively to decrease the radius of curvature of the arcuate segment of the spring and allows a balance of forces in both direction of rotation of the telescope.
  • the purpose of the present invention is to provide a solution simple, reliable, likely to last a very long time of life, therefore practically with very little wear and suitable to allow fine adjustment of the force necessary for moving the rotating bezel.
  • the present invention relates to a watch case as defined in claim 1.
  • the rotating bezel mechanism which is associated with the case middle B has a ring 2 whose section has an L shape.
  • the vertical part of this section in L is driven on a cylindrical surface of the middle box B ( Figures 3, 4), while the horizontal part of this L-shaped section rests against a span of this middle box B.
  • the outer face of the vertical part of the L-shaped section of ring 2 has first marks of angular positioning 2a, of which the angular distances are equal in the same way as those of a toothing, which are therefore integral with the middle part and whose profile, seen in plan, forms a regular festoon.
  • the shape of this festoon can be more or less accentuated depending on the characteristics sought when moving the telescope rotating 1 mounted on the ring 1.
  • these marks are 24 in number, and therefore determine positions angular spaced 15 ° from each other.
  • the rotating bezel 1 mounted on the ring 2 has on the one hand three spaced apart radial guide tracks 1a 120 ° from each other and arranged in three portions 1b which are inside the rotating bezel 1.
  • An annular groove 1c opens out inside the rotating bezel 1 and passes substantially through the center of the thickness of the three re-entrant portions 1b.
  • Each radial guide slide 1a receives a roller 4 which has a groove 4a formed substantially in the middle of the roller 4 and which coincides with the annular groove 1c.
  • a spring 3 having the shape of a closed loop is arranged in the annular groove 1c. This spring 3 surrounds the three rollers 4 and engages in their respective grooves 4a, now these pebbles 4 in the bottom of three of the first marks 2a spaced 120 ° apart, that is to say in the example described, spaced at an angle equal to 8 steps, that is to say 8 marks. Simultaneous engagement of spring 3 in closed loop in the annular groove 1c of the telescope 1 and in the grooves 4a of the rollers 4, secures these rollers 4 with the telescope 1 while allowing them to move within radial guide slides 1a.
  • These three rollers 4 constitute second marks of angular positioning, made integral in rotation with the rotating bezel 1 by the radial slides 1a.
  • the number of the first fixed angular references 2a is therefore a multiple of the number of second marks 4 which are at least three in number, to ensure the centering of the telescope rotating 1 relative to ring 2. Thanks to this relationship between the number of first and second marks 2a, 4, the second marks 4 are simultaneously engaged with three of first marks 2a, in each of the 24 defined positions by the first 24 angular positioning marks.
  • the three positioning rollers angular 4 occupy the most near the center of the rotating bezel 1 and the spring 3 is not, or is very little deformed in this position.
  • the profile of the side face between two positioning marks angular 2a forms a convex curve.
  • the force stored following the deformation of the spring 3 can be released by developing a couple that ends the displacement from the rotating bezel 1 to the first positioning mark 2a next.
  • the rotating bezel 1 is held on the ring 2 thanks to two conical notches, one 1d formed on the bezel rotating 1, the other 2d formed on the ring 2 and engaged at force into each other, as shown in Figures 3 and 4.
  • these conical surfaces 1d, 2d are applied one against the other thanks to a flat elastic ring 5, the internal edge bears against the upper edge of the ring 2 and whose outer edge is trapped between a ring 6 bearing indications intended to be moved angularly by the rotating bezel 1 and fixed in a notch 1e of this rotating bezel, as illustrated by FIGS. 3 and 4.
  • This flat ring 5 is deformed in its plane, taking a frustoconical shape, as illustrated, which allows apply the two conical notches 1d, 2d one against the other elastically.
  • This axial elastic pressure is low, so that in lightly pressing the rotating bezel 1 to make it turn, it automatically causes a slight displacement axial of this telescope, even without realizing it, allowing to suppress, or at least to reduce strongly the friction resulting from the contact between the notches conical 1d and 2d.
  • the three associated angular positioning rollers 4 with closed loop spring 3 allow perfect balancing positioning forces around the axis of rotation of the rotating bezel 1, this as well when the rollers 4 are in rest position in the first marks fixed angular positioning 2a of the ring 2, that when they are between two determined angular positions by these fixed angular positioning marks 2a, of so that the rotating bezel is never offset by the forces exerted by the closed-loop spring 3, 13, 23.
  • the second embodiment illustrated by the figures 5 to 7 differs essentially from the first by the fact that these are no longer rollers 4 which constitute the second positioning marks, but these are three bulges 13a formed directly during the cutting of the spring 13 into closed loop, which engage in positioning marks 2a of the ring 2.
  • the radial guidance of the second marks formed by the bulges 13a is obtained by cylindrical guides 14 driven into openings cut out in the center of the bulges 13a. These guides 14 are engaged in three grooves 1a formed in three portions 1b which are inside the rotating bezel 1, exactly like the rollers 4 of the first embodiment.
  • the rest of the rotating bezel mechanism is similar to the first embodiment.
  • the position of the ring flat elastic 5 which is used to apply the two conical notches 1d, 2d against each other is changed in this form but its function remains the same.
  • the positions of the first and of the second angular marks are reversed compared to previous embodiments, that is, it is the rotating bezel 21 which presents the first marks of angular positioning 21a, while the looped spring closed 23 has a fixed angular position relative to a ring 22 secured to the case middle B, corresponding to ring 2 of the previous execution forms.
  • the closed loop spring contour 23 seen in plan is cut out to provide three protrusions 23a spaced 120 ° apart each other, in order to constitute the second landmarks of angular positioning, intended to engage simultaneously in three of the first angular positioning marks 21a whose number is a multiple of these seconds angular positioning marks 23a.
  • Each protuberance 23a is associated with a radial projection 23b centered on the same radius as each protuberance 23a and which is directed towards the inside of the loop spring closed 23.
  • Each of these radial projections 23b is mounted for radial sliding in a radial guide slide 22a formed in the ring 22 driven out on the middle part of box B.
  • the radial projections 23b have a rectangular section, so that they guide the spring 23 during its deformation following rotation of the rotating bezel 21 and they force the closed-loop spring 23, to distort in his plan.
  • the internal periphery of the closed-loop spring 23 comprises three projections 23c which are engaged in three grooves 22b formed in the external lateral face of the ring 22, so that the spring 23 is retained axially.
  • the spring 3, 13, 23 has a section rectangular whose long side is arranged in the plane of loops formed by these springs 3, 13, 23.
  • the forces communicated to these springs to deform them in three directions radials are therefore directed in the plane of the loops formed by these springs 3, 13, 23 and therefore also parallel to the long sides of the sections of these springs.
  • the advantage of such springs is that they can be cut from steel sheets, allowing optimal manufacturing. These springs could however have a section of another shape, square or circular, then forming an O-ring spring.
  • the shape of the spring 3, 13, 23 at rest, plan view can go from the circle to the polygon with its sides and / or its vertices rounded or not.
  • the number of second marks 4, 13a, 23a is at least three in number, but could be higher depending on the case.
  • the number of first benchmarks 2a, 21a is always a multiple of the number of seconds marks, so that all the second marks 4, 13a, 23a are simultaneously engaged with one of the first landmarks 2a, 21a.
  • the rotating bezel 1 is identical to that of the shapes of execution of FIGS. 1 to 7. What changes in this variant, these are the marks 32a formed on the ring 32, which are jagged and the shape of the three bulges 33a of the spring 33 in closed loop, which has a complementary shape to that separating two marks 32a in teeth of saw, so as to engage with this toothing 32a and to not allow the rotation of the rotating bezel 1 only counterclockwise in the example illustrated by this variant. Others elements conform fully to the form of execution Figures 5 to 7.
  • Figure 13 illustrates another variant of the form of Figures 5 to 7, in which the cylindrical guides 44 hunted in openings cut in the center bulges 43a of the spring 43 in closed loop, comprise three portions of increasing diameters 44a, 44b, 44c, one 44a driven into the opening of the spring 43, the next 44b which serves as a pivoting surface for a roller 45, while the third portion 44c serves as an axial stop to retain the roller 45.
  • the three rollers 45 distributed angularly as described above are engaged with the marks 2a of the ring 2 and can rotate around the cylindrical guides 44 when the telescope 1 is driven in rotation by driving the spring 43, thanks to the portions 44a cylindrical guides 44 engaged with the slides of radial guide 1a of the telescope 1, identical to the telescope Figures 1 to 4.
