Definitions

  • the invention relates to a hairspring adapted to the assembly system described in the patent applications.
  • EP 2 860 591 and EP 2 860 591 that is to say a spiral blocked elastically on an axis by a washer.
  • the document EP 1 868 045 discloses a spiral shell whose geometry makes it possible to maintain a constant distance between the junction point and the center of the ferrule during its driving on a balance shaft.
  • the object of the present invention is to overcome all or part of the aforementioned drawbacks by proposing a hairspring whose one-piece shell is adapted to be mounted using the assembly system described in the patent applications.
  • EP 2 860 591 and EP 2 860 592 are adapted to be mounted using the assembly system described in the patent applications.
  • the invention relates to a spiral comprising a blade wound on itself in a plurality of turns, the inner coil being shaped with a ferrule comprising a band extending substantially in the form of a polygon characterized in that that the band includes, each of the vertices of said polygon, a bulge extending radially towards the inner coil, the point of attachment between the inner coil and the ferrule being located on one of the bulges of the ferrule which is symmetrical with respect to the axis passing through the center of the ferrule and said point of attachment and in that the distance between the center of the ferrule and the end of each bulge is substantially constant to provide an outer contour at each bulge which has two walls extending axially substantially parallel to each other with respect to the segment formed between the center of the ferrule and the end of said bulge.
  • the outer contour is optimized so that the spring washer mainly squeezes the hairspring at the vertices of the band of its shell. Indeed, even if the bulges are not pinched by the washer, its two substantially parallel walls oriented substantially orthogonally with respect to the peripheral wall of the washer advantageously avoid grits.
  • the invention relates to a resonator for a timepiece characterized in that it comprises an axis on which is fitted a balance and a hairspring according to one of the preceding variants.
  • the invention relates to a hairspring whose one-piece shell is adapted to the assembly system described in the patent applications.
  • EP 2 860 591 and EP 2 860 592 This assembly system is provided for a part whose material has no usable plastic field, that is to say with a very small plastic area, with a member comprising another type of material.
  • this assembly is made necessary by the growing share of fragile materials such as those based on silicon such as monocrystalline silicon (or polycrystalline silicon) doped or not, silicon oxide such as quartz or silica , monocrystalline or polycrystalline corundum or more generally alumina, silicon nitride and silicon carbide.
  • silicon such as monocrystalline silicon (or polycrystalline silicon) doped or not, silicon oxide such as quartz or silica , monocrystalline or polycrystalline corundum or more generally alumina, silicon nitride and silicon carbide.
  • the hairspring 1 comprises a blade 3 wound on itself in a plurality of turns, the inner coil P I being shaped with a shell 5, 25, 45, 65 having a strip 7, 27, 47, 67 extending substantially in the form of a polygon.
  • the strip 7, 27, 47, 67 comprises a polygon in the shape of a triangle or diamond of width L 1 , L 2 , L 3 , L 4 , L 5 , L 6 , L 7 , L 8 , substantially constant.
  • the strip 7, 27, 47, 67 comprises, at each of the vertices of the polygon, a bulge 2, 4, 8, 22, 24, 26, 28, 42, 44, 48, 62, 64, 68 of respective widths L ' 2 , L' 4 , L ' 6 , L' 8 , extending radially towards the inner turn P I , to form the portions S 1 , S 2 , S 3 , S 4 of external outline of the shell 5, 25, 45, 65 which are furthest from the center C of the shell 5, 25, 45, 65, the center C being formed by the center of the circle inscribed in the opening of the shell 5 , 25, 45, 65.
  • the point of attachment S 1 between the inner turn P I and the ferrule 5, 45, 65 is situated on a 2, 52, 72 of the bulges 2, 4, 8, 42, 44, 48, 62, 64, 68 5, 45, 65. It is also noted that the ferrule 5, 45, 65 is symmetrical with respect to the axis passing through the center C of the ferrule 5, 45, 65 and the point of attachment S 1 .
  • the distance between the center C of the shell 5, 45, 65 and the end S 1 , S 2 , S 3 of each bulge 2, 4, 8, 42, 44, 48, 62 , 64, 68 is substantially constant to provide an outer contour at each bulge 2, 4, 8, 42, 44, 48, 62, 64, 68 which has two walls 2 1 -2 2 , 4 1 -4 2 , 8 1 -8 2 , 42 1 -42 2 , 44 1 -44 2 , 48 1 -48 2 , 62 1 -62 2 , 64 1 -64 2 , 68 1 -68 2 extending axially and substantially parallel between them but also parallel to the segment formed between the center C of the shell and the end S 1 , S 2 , S 3 of each bulge 2, 4, 8, 42, 44, 48, 62, 64, 68 associated .
  • the distance between the two walls 2 1 -2 2 of the bulge 2 is smaller than those of the walls 4 1 -4 2 , 8 1 -8 2 respectively of the bulges 4 and 8 whereas in the figures 8 and 9 the distances between the two walls 42 1 -42 2 , 44 1 -44 2 , 48 1 -48 2 , 62 1 -62 2 , 64 1 -64 2 , 68 1 -68 2 bulges respectively 42, 44, 48 , 62, 64, 68 are substantially constant.
  • the strip 7, 27, 47, 67 is bent towards the center C of the shell 5, 25, 45, 65 between each vertex of the polygon so as to form at least three clamping points O 1 , Q 2 , Q 3 , Q 4 arranged to fit on an axis 11, 11 '.
  • the band 47 is more curved than the strips 7, 27, 67 respectively of the figures 3 , 9 and 10 .
  • the strip 7, 27 further comprises a thickening 2 ', 22' of width L " 2 extending radially from the inner wall of the strip 7, 27 towards the center C of the ferrule 5, 25 at the apex of the triangle having the point of attachment S 1 in order to avoid the displacement of the point of attachment S 1 during a deformation F 1 of the strip 7, 27 caused by the reception of the axis 11, 11 'larger than the opening between the clamping points Q 1 , Q 2 , Q 3 , Q 4 .
  • figures 8 and 9 that the band 47, 67 does not include such a thickening. It is therefore understood that the latter is not an essential feature of the invention.
  • the strip 7, 47, 67 comprises, on the portion 12, 52, 72 between two peaks of the triangle which has the bulges 4-8, 44-48 and 64-68 and which is opposite the point d S 1 attachment relative to the center C of the ferrule 5, 45, 65, a fourth bulge 6, 46, 66 of width L ' 6 extending radially towards the inner turn P I to position the center of gravity of the ferrule 5, 45, 65 at the center C of the opening of the ferrule 5, 45, 65.
  • the thickening 2 ', 22' in order to avoid the displacement of the point of attachment S 1 during a deformation F 1 of the strip 7, 27, 47, 67, it is also possible to vary the width of the strip 7, 27, 47, 67 between the vertices of the polygon, that is to say having a different width or a non-constant width.
  • the figure 9 shows an example of the non-constant width.
  • the shell 65 has an allowance of about 10% localized at the widths L 1 and L 3 , that is to say at the points of clamping Q 1 , Q 2 , Q 3 , compared to the rest of the band 67, that is to say with respect to the widths L 2 , L 4 , L 5 , L 6 , L 7 and L 8 .
  • the modification of the rigidity of the latter to keep the center of the spiral 1 coaxial with its axis 11 can be done by changing the thickness of the band 7, 27, 47, 67 and / or by changing the length of the strip 7, 27, 47, 67 between the polygon apices and / or by width of the bulges 2, 4, 6, 22, 24, 26, 28, 42, 44, 48, 62, 64, 68 or thickenings 2 ', 22' on the strip 7, 27, 47, 67 and / or leaving the band 7, 27, 47, 67.
  • the distance CI 1 , -L " 2 is substantially equal to the distances CI 2 and CI 3 and that the distances L 2 -L ' 2 , L 4 -L' 4 and L 8 -L ' 8 are substantially equal, which explains that the distances CS 1 , CS 2 and CS 3 are substantially equal to the figure 3 whereas this equality is more immediately perceptible to Figures 8 to 10 .
  • the hairspring 1 can thus be formed in a manner that is in no way limitative from a silicon-based material such as doped or uncropped doped monocrystalline silicon, doped or non-doped polycrystalline silicon, doped or unopened monocrystalline silicon, and coated with a silicon oxide, doped polycrystalline silicon or not and coated with an oxide of silicon, silicon oxide, quartz, silica, silicon nitride, silicon nitride coated with an oxide of silicon, silicon carbide or silicon carbide coated with a silicon oxide, without risk that the material is broken by a washer 10,10 'during the elastic clamping.
  • the spiral 1 can thus be formed in no way limiting from monocrystalline corundum, polycrystalline corundum or alumina.
  • the washer 10 is a perfect ring, that is to say a disc with an opening 18, having an upper face 19 and a lower face 16 which can be used to tighten the hairspring 1.
  • the edges of the washer 10 may include bevels 15 to avoid grits and smudges during manufacture.
  • the washer 10 ' is a ring, that is to say a disc with an opening 18', having an upper face 19 'and a lower face 16'.
  • the upper face 19 ' communicates with the opening 18' with the aid of a conical surface 17 'and is used to tighten the hairspring 1.
  • the edges of the washer 10 ' may comprise bevels 15' to avoid grits.
  • the hairspring 1 comprises an internal turn P I following a Grossmann type curve and an outer turn P E partially thickened to improve the concentricity of its contraction and expansion.
