Definitions

  • This fluid-tight mounting for a control member for a watch movement or like mechanism comprises a wind- [21] APPLNO" 153,178 ing button having a member of synthetic material fitted therein, in which the flange-shaped head of a [30 Foreign Application priority Data shah: for ⁇ (giving thfe :ssociaged part is emlbedged.

  • the socket [221 ⁇ 1.8. (i1.
  • the present invention relates in general to fluid-tight watches and like mechanisms and has specific reference to improvements in the dustand water-tight mounting of a control member for watch movements.
  • Mechanisms designed for controlling dust-andwater-tight watches and the like are already known wherein the degree of tightness is obtained by the simple contact between a winding button and a the tubular piece extending through the watch case, without interposing any packing means.
  • the button core engaging the tubular piece is provided with a bead of synthetic material, and in other constructions, the winding button comprises one or a plurality of beads of synthetic material surrounding the tubular piece.
  • the winding button necessarily consists at least partially of synthetic material adapted to undergo a certain elastic deformation.
  • synthetic material is more delicate than metal and the deformation of this synthetic material as a consequence of radial stress is transmitted through the distorted material to the shank and to the winding mechanism.
  • the present invention provides a fluidtight control member for a watch movement, compromising a button for driving a shank of the watch movement and extending from the wall of the watch case through a tubular piece, the fluid-tightness being obtained at least by mutual contact between the button and the tubular piece, without interposing any packing therebetween.
  • the fluid-tight control member the characterized in that the button engages a socket rigid with the tubular piece and receiving the tubular piece through its bottom. The button engages with the socket and is both rotatable and axially movable therein.
  • the socket includes an additional barrier for preventing the ingress of duct and water comprising an O-ring or a gasket interposed between the button and the socket.
  • the winding button of this invention provides the same advantageous features as a screw-inbutton by the interposition of a sealing gasket at the inlet end of the projection while avoiding certain inconveniences, such as, notably, the heretofore necessary slow actuation of the screwed button and the excessive compression of the O-ring or like gasket disposed at the inlet end of the projection.
  • FIG. 1 A typical form of embodiment of the invention is illustrated by way of example in the single FIGURE of the attached drawing.
  • the mechanism controlled by this button is not shown, as it is no part of the present invention.
  • the winding button illustrated in the drawing comprises a metallic outer portion 1 in which a piece 2 of synthetic material is tightly fitted. This piece 2 contacts directly the tubular piece 3 extending through a wall of the watch casing (not shown).
  • the button further comprises a metal core 4 of which the upper or outer portion 4a constitutes a flange embedded in the synthetic material 2.
  • This piece 2 of synthetic material is retained in the corresponding cavity of button 1 by an annular metal member 5 crimped therein.
  • the button 1 fits within a metal socket 6 which is rigid with the tubular piece 3.
  • the fluid-tightness of the control device is obtained by using three successive barriers.
  • the first barrier from the interior of the watch case consists of an O-ring 8 fitted in a groove 9 of the core 4 and engaging the inner wall of tubular piece 3.
  • the second barrier consists of three successive inner beads 10, 11 and 12 formed in the synthetic member 2 and these beads are compressed against the outer wall of tubular piece 3. In the right-hand half of the figure, these three beads are shown in their free condition, i.e. before their actual compression.
  • the third barrier consists of another 0- ring 13 of the same type as ring 8 but fitted in a groove 14 formed in button 1 and engaging the socket 6.
  • This O-ring 13 permits easy axial sliding movements of the button on socket 6 while safely protecting the synthetic material 2 constituting the main barrier protecting the interior of the watch case against the ingress of dust and water, notably sea-water salt likely to attack and damage the synthetic material 2. In case of shock applied to the socket 6, no stress is transmitted to the button l.
  • a fluidtight winding mechanism for a watch movement and the like comprising: a socket member having in a bottom portion thereof means defining an opening; a tubular member extending through said opening and rigidly connected to said socket member; a button movably mounted within said socket member to undergo both manual rotational movement and manual axial sliding movement and having an inner portion composed of deformable synthetic material in compressively deformed contact with said tubular member and cooperative therewith to establish a fluidtight connection therebetween; and a driving shank extending into said tubular member and having at one end a head portion embedded in and connected to said synthetic material and connectable at the other end to a member to be wound.
  • a fluidtight winding mechanism including an O-ring type packing interposed between said button and said socket member establishing a fluidtight connection therebetween.
  • a fluidtight winding mechanism according to claim 1; wherein said inner portion of said synthetic material in compressively deformed contact with said tubular member includes a plurality of annular beads
