Definitions

  • This invention is concerned with a timepiece case, for example for a watch, which has a shock-absorbing ring of elastic material for securing the movement in the case.
  • the present invention precisely aims at avoiding this drawback and has for its object a timepiece case having a shock-absorbing ring of elastic material for securing the movement in the case and for giving fluid tightness to certain elements of the casing.
  • FIGURES 1 and 2 are cross sections of parts of the timepiece case, with recessed bottom and single shell, respectively, for a first modification.
  • FIGURES 3 and 4 are cross sections of parts of timepiece cases according to a second modification.
  • the timepiece case according to the invention consists of a bottom 1 and of a middle 2 (FIGURES 1 and 3), or of a bottom-middle 3 (FIGURES 3 and 4), and a crystal 4 a movement 5 is mounted on a substantially rectangular cross-sectional elastic ring 6.
  • the middle 2 and the bottom-middle 3, respectively, have an annular groove 7.
  • the height of the elastic ring 6 is selected in such a manner as to enable it to absorb axial impacts, while during radial impacts, the middle part of ring 6 can deform itself in groove 7. This makes it possible to reduce the thickness of the elastic joint and consequently, to reduce the diameter of the casing.
  • elastic ring 6 has a groove 15 cooperating with a shoulder 16 of the fitting frame 17.
  • the latter comprises a shoulder 18 on which is secured a shoulder 19 of movement 5.
  • a shoulder 20 of elastic ring 6 is directly mounted on movement 5.
  • the shoulder 20 is reinforced by at least one annular support 21, profiled in a Y, which is partially embedded in the resilient ring 6.
  • a timepiece casing comprising: an annularly grooved inner surface having side walls; and resilient mounting means spanning and extending beyond said side walls of said annularly grooved inner surface and deformable therein when said casing is subjected to axial or radial impact.
  • a timepiece casing according to claim 1 including a crystal mounted on said casing; and wherein said resilient mounting means is compressed between said crystal and said casing to fluid-tightly seal said casing.
  • a timepiece casing according to claim 1 including a fitting frame having a supporting flange for supporting a movement and having an outwardly extending projection; and wherein said resilient mounting means has an accommodating recess receiving said outwardly extending projection.
  • a timepiece casing comprising: an annularly grooved inner surface; a crystal mounted on said casing; and resilient mounting means disposed adjacent said annularly grooved inner surface for fluid-tightly sealing said crystal and said casing and deformable into said annularly grooved inner surface when said casing is subjected to axial or radial impacts.
  • a timepiece casing according to claim 6 including a fitting frame having a supporting flange for supporting a movement and having an outwardly extending projection; and wherein said resilient mounting means has an accommodating recess receiving said outwardly extending projection.
