  • the transition from the first disassembled insertion position to the second assembled and locked position is carried out under the action of forces exerted by an operator: an axial force to overcome the resistant force of the repulsion means and bringing the first component 1 and the second component 10 into contact, and a torque to bring them into an angular indexing position.
  • the first component 1 and the second component 10 In the second assembled and locked position, the first component 1 and the second component 10 have, relative to each other, a second angular orientation different from the first angular orientation.
  • the first component 1 and the second component 10 are held axially against the resistant force exerted by these repulsion means, by the effect of a bayonet adjustment, achieved by the application of the axial and torque forces impressed by the operator, between at least two flanges 2 and at least two wings 12.
  • This joining of the first component 1 and the second component 10, by bayonet adjustment, in particular around an axial direction D, is reversible, and allows their disassembly.
  • this disassembly requires from an operator efforts similar to those exerted during assembly, this disassembly preferably requires the use of a tool special, cooperating for example with peripheral holes or notches, or the like, and cannot be the result of clumsiness or exposure to particular external physical factors.
  • this covering sub-assembly 100 comprises at least a third component 20, which is arranged to be interposed radially, or respectively axially, between the first component 1 and the second component 10 and fixed in rotation relative to one of them, and which comprises at least one zone 50 which is elastically deformable radially, or respectively axially.

  • This deformable zone 50 is arranged to oppose a resistive torque of variable moment to any relative tangential torque between the first component 1 and said second component 10.
  • This deformable zone 50 comprises at least one notch 26, which is arranged to cooperate with at least one complementary relief 18 that comprises that of the components 1, 10, with respect to which the third component 20 is free to rotate. And any passage of such a notch 26 on a complementary relief 18 generates a resistant torque which tends to oppose the relative movement of rotation between the first component 1 and the second component 10, at least one such notch 26 being arranged for the relative angular indexing between the first component 1 and the second component 10.
  • the invention relates to a covering sub-assembly 100 for a timepiece or watch, comprising at least one seal 9 between a first component 1 and a second component 10.

  • At least one such notch 26 is arranged to the relative angular indexing between the first component 1 and the second component 10. More particularly the couple formed by a particular notch 26 and a particular complementary relief 18 corresponds to the exercise of a maximum resistant force, and this particular couple corresponds to a preferred indexing and locking position in the indexed position.
  • this third component 20 is a closed ring, substantially toroidal.
  • the third component 20 is made completely of elastic material.
  • the first component 1 comprises at least one housing 6 for stopping an anti-rotation lug 29 that the third component 20 comprises.
  • the deformable zone 50 comprises a plurality of notches 26, which are arranged to oppose successive resistance to a complementary relief 18. More particularly still, in the same such deformable zone 50, the successive notches 26 are arranged to oppose resistance increasing to a complementary relief 18, during the growth of the relative angle between the first component 1 and the second component 10.
  • the resistant force can be all the more important as the number of notches 26 and complementary reliefs 18 in cooperation is high. It is therefore possible to play on the number of successive notches, and / or on the height of each notch, or, more exactly, the force resisting the passage of each notch.
  • the user prints a progressive torque to print the relative rotation between the first component 1 and the second component 10.
  • the operator carrying out the assembly of the sub-assembly 100 encounters a first resistance during the putting in cooperation of a first notch 26 with a first complementary relief 18. The resistive torque progresses during the relative rotation.
  • the first notch 26 and the first complementary relief 18 are unique (or are each replaced by a plurality of such couples, of identical profile and resistance, and arranged at the periphery of the profile so as to interfere with same time: which amounts to a single resulting notch, and a single relief; this possibility of duplicating profiles in phase is not explained in more detail, and is applicable to any variant of the invention).
  • the minimal applied axial force necessarily corresponds to the sealing of the seal (s) 9.
  • the first notch 26 and the first complementary relief 18 constitute the housing 6 and l pin 29 for indexing the second component 10 in angular position relative to the first component 1. For example, three notches at 120 ° cooperate with complementary reliefs also at 120 °, the operator feels a single passage of hard point when the three 120 ° notches act simultaneously.
  • the sub-assembly 100 comprises several notches 26 and several complementary reliefs 18, arranged relatively with respect to each other so that, at the start of the relative rotation, a single clearance-boss pair is in cooperation, then, after a certain angle, two clearance-boss couples are in simultaneous cooperation, and so on, the peak of cumulative resistant torque increasing with each passage of hard point, to reach, at the indexing angle, the value maximum. The operator thus encounters a feeling of increasing resistance.
  • the seal exists as soon as the bayonet is put in, and the mechanism according to the invention is arranged so that, as in the previous case of a single bump, securing the seal of the seal (s) 9 is ensured from the passage of this first bump, since then no loosening can occur without the voluntary action of an operator.
  • the figure 11 illustrates such an example, and superimposes the torque profile obtained with a particular variant of the invention, in solid lines, corresponding to the passage of three successive hard points, also called bumps, before immobilization in the indexing position at the angle ⁇ M, with, for comparison, the increase in torque in the last degrees of closure of a conventional traditional face of the prior art (which may in particular require an angular amplitude of the order of two turns), in broken lines .
  • the only resistance to rotation is the mechanical friction forces due in particular to the axial forces generated by the compression of a seal at the end of the stroke, and to the elastic deformation of the components present during the permanent mechanical blocking.
  • the angular value ⁇ V corresponding to the maximum screwing with a torque ⁇ V corresponds to the end of a torque growth curve, the slope of which becomes extremely steep in the vicinity of this value ⁇ V: which means that a subset screwed which is then subjected to a significant effort risks unscrewing, without any guardrail to prevent total unscrewing, or loss of tightness, since the torque necessary for unscrewing is then declining, and the energy to be supplied for the lower unscrewing than in the case of the invention.
  • the same hump cooperates successively with several clearances, which may each be of the same depth in a particular embodiment, thus creating a fixed resistance force value, and which must be passed repeatedly to arrive in the closed and indexed position. It is, again, possible to mix these last two variants, everything is possible, the machining to be carried out is not very complex.
  • the invention requires, during assembly, the successive crossing, in a sort of ramp, of several bumps of torque of increasing resistance, but also upon dismantling, since, from the final position indexed ⁇ M, in particular on a possible mechanical stop (which is however not necessary within the framework of the invention), any application of a sudden force results, in the worst case, by the crossing of a single bump, without total disassembly, with a visual shift, and above all without loss of tightness or risk of pollution of inside the watch.
  • the operator must successively cross three thresholds, visible optically due to the offset, before having a loss of tightness.
  • each notch is identical, and its passage opposes the same resisting torque.
  • the multiplying coefficient of resistant torque from one notch to another, can in particular be between 1.2 and 2.2.
  • the invention is advantageous because it is perfectly compatible with watchmaking dimensions, while having a capacity for a high resistant force, which can reach several N.m, for example in the case of a third component made of at least partially amorphous metallic material. Even with more common materials for the manufacture of technical rings, POM, polyurethane or similar, and axial and radial dimensions of a few tenths of a millimeter, the resistant torque easily exceeds one N.m.
  • the dismantling of the mechanism according to the invention requires the maintenance of the application of any effort of accidental origin. during a large angular stroke, from 7 to 8 ° for the crossing of a single bump in the example illustrated, the security still being ensured if several bumps succeed, while, in screwed solution of the prior art, disassembly is consumed in an angular travel of the order of only 2 °, and therefore the loss of tightness also.
  • the angular indexing can be guaranteed by a stop 28 for limiting the travel. But, preferably, it is the third component 20 which fulfills, de facto, the stop function, by the exercise of a particularly high resistant torque. Such a mechanical stop is therefore not absolutely necessary.
  • the invention thus makes it possible to prevent any unintentional and involuntary disassembly of the sub-assembly 100, for example under the effect of vibrations, of successive expansion cycles, by unfortunate use of the user, or other.
  • disassembly requires a special tool that is not sold, which ensures that maintenance is carried out by after-sales personnel with the required qualifications.
  • the Figures 1 to 7 illustrate a first variant, where the third component 20 is a ring 24 held in abutment on a flat surface 5 that includes the edges 2 of the first component 1 consisting of a middle part, and the extensions of these edges 2.
  • This ring 24 is well secured angularly with the first component 1, by anti-rotation lugs 29 whose external contours are accommodated in a complementary manner in housings 6 of the middle part.
  • the three components present here each have the same contours three times, equally distributed at 120 °.
  • the second component 10 is a bottom, manipulated by an operator, preferably using a special tool. Above the skirt 11 of this bottom 10, the rim 12 is bypassed so as to be able to gradually deform the ring 24 during its rotation (counterclockwise for these figures).
  • This rim 12 comprises in particular a ramp 18 which causes the opposing surfaces of the ring 24 to bend.
  • This ramp is here followed by a clearance 17 which allows the movement of projecting notches 27, 28, which the ring 24 has internally, the l one 27 is substantially parallel to a clearance 25 which the ring 24 has on its outer face, at the level of such a deformable zone 50, while the other 28 faces a substantially cylindrical bearing surface of the ring 24
  • a recess 26 separates these projecting notches 27 and 28 on the inside of the ring 24.
  • the figures 8 to 10 illustrate a second variant, quite similar to the previous one, also comprising a repetition at 120 °, the bottom 10 comprises here, after the ramp 18 and separated by intermediate reliefs, three clearances 171, 172, 173, which are arranged to cooperate successively with bosses 271, 272, 273 of the ring.
  • the angular reference 19 of the base 10 makes it possible to locate the relative angular position of the middle part 1 and of the base 10: 50 ° on the figure 8 , 30 ° on the figure 9 , 0 ° on the figure 10 .
  • the sub-assembly 100 comprises components 1 and 10 made of different materials, with different coefficients of expansion, or also fragile or hard materials (ceramic, sapphire), which do not not allow standard fixing methods.
  • ceramic, sapphire fragile or hard materials
  • the third component 20 is preferably a ring, which can be made of different materials, in particular POM, polyurethane, polymer-based material, or elastomer, at least partially amorphous metal alloy, the material chosen determining the maximum tightening torque, thus a amorphous alloy ring allows a tightening torque of about 3.2 Nm, similar to that usual for a bottom screwed onto a middle part, for a gasket 9 of the same size.
  • This ring can also be made of amorphous metal, stainless steel, CuBe, "Liquidmetal ⁇ ", or even be bi-material, for example with a core of plastic material with molded inserts, metallic, or ceramic, or other.
  • the advantage of such a ring, preferably in an elastic polymer material or the like, is its ease of accommodation in a volume whose free space is very limited, where it is impossible to safely implant a metallic element capable to break.
  • the material of the third component 20 can also be more complex, in particular in the form of an elastomer type material loaded with technical fibers such as “Kevlar®” or the like, or with an anti-wear additive such as said polytetrafluoroethylene. PTFE, or other.
  • An important advantage of the invention is that it requires neither drilling nor tapping, but only simple machining which can be carried out with a certain ease, thus avoiding any soiling or pollution of the watch, and allowing a moderate cost.
  • the first component 1 is a middle part and the second component 10 is a background.
  • the presence of at least one seal is required.
  • the first component 1 is a base and the second component 10 is an appearance part, such as a medallion, or the like, attached to this base, in which case a seal between them is not necessary, and the presence of a spring which may be perfectly sufficient in a variant comprising repulsion means.
  • the first component 1 is a middle part and the second component 10 is a flange or bezel, as visible on the figure 13 .
  • This case is well suited to a variant in which a first component and a second component tend to be distant from each other, by magnetic repulsion or by an elastic element such as a rod, that is to say a thin ring, not necessarily closed, or more particularly a rod comprising segments similar to a ratchet to easily authorize only a unidirectional maneuver, as in the particular case of use of the invention for a unidirectional telescope.
  • a rod may be filiform, of substantially round section, or else of rectangular section, or the like.
