Definitions

  • a fluid-tight joint between a crystal and a watch case is made with an annular gasket, the inner periphery of which in confined by an annular elastic metallic member which is elastically deformed as the edge of the crystal is pressed against the gasket by a threaded bezel.
  • the elastic member improves the effectiveness of the joint and avoids damage to the gasket by excessive tightening of the bezel.
  • a known system proposes to make more efficient the support of the movement by the interposition of a wavy spring acting in a direction parallel to the axis of the movement and bearing against the base of a bezel bearing the glass and force-fitted a part of the case forming a fastening notch.
  • This spring has an annular shape and is lodged in a groove made in a fitting frame. The axial action of the spring on the frame and against the base of the glass improves the water tightness of the latter.
  • This system requires a large fitting circle the diameter of which is in any event greater than that of the frame in order that the groove in which is lodged the spring exceeds the periphery of the frame and allows the spring to reach the base of the bezel.
  • Such an arrangement entails the construction of watch cases the diameter of which is relatively large with respect to that of the movement and in which the wall of the middle is rather thin.
  • water tight cases are generally provided with a tube driven into the middle and that the wall of the tube must be sufiiciently thick so that the driven segment of the tube be guided at a suitable length in order to remain in an axis parallel to the plane of the movement.
  • the present invention has for an object the fastening of a timepiece movement surrounded by a fitting frame having means bearing at least indirectly the glass, characterised in that said means consists of elastic elements extending outside the fitting diameter of said frame.
  • FIGURE 1 is a cross-sectional view thereof.
  • FIGURE 2 shows in cross-section a detail of FIG- URE 1.
  • This case comprises a one piece bottom-middle. Movement 2 is secured to the fitting frame 3 by a screw not shown finding support on shoulder 4 of the fitting frame and on movement 2.
  • This fitting frame rests in its lower part on a shoulder 5 of the case and has at its upper part a ring 6 extending radially outside the fitting diameter of frame 3.
  • This ring is set on this frame and can ice consist preferably of a material different from that of the latter.
  • the ring 6 can be of nickel or steel, metals which have a better coefiicient of elasticity than brass.
  • the ring 6 is provided on its outside periphery with an annular segment 7 perpendicular to the plane of the movement and coming to bear against base 8 of glass 9.
  • a tube 13 driven in the bezel-middle is intended for the passage of the winding stem.
  • This tube penetrates by its inner extremity in the case and a slot 14 is made in the fitting frame 3 in order to permit its introduction.
  • This tube communicates with movement 2 through opening 15 of frame 3.
  • a circular groove 16 is made under ring 6 in the bottom-middle 1 and in the part of the tube protruding inside the case. This groove allows the ring to deform under the pressure exerted by the base 8 of the glass.
  • a watch having a movement surrounded by a frame having an upper recessed shoulder fitting in an opening in the middle of the watch, and having means bearing at least indirectly against the watch glass of said watch, the improvement whereby said means consist of an elastic, metallic, element on said shoulder, said element having an outer peripheral rim forming one wall of a housing adapted to receive a packing joint.
  • said elastic element consists of a ring having a part parallel to the plane of said movement, said part having one extremity integral with said frame and a free extremity having a segment perpendicular said plane, said glass having a base supported by said last segment.
  • Watch according to claim 1 wherein said recessed shoulder has a vertical portion and said element has an outer peripheral rim and a central part surrounded thereby and sit on said shoulder, said vertical portion of said FOREIGN PATENTS shoulder being inclined over said central part and defining with said rim a housing for a Water tight packing joint, 327025 1/1958 Switzerland said ring serving to limit the axial compression of said 336,016 3/1959 swltlellandjoint. 371,054 9/ 1963 Switzerland.
