Definitions

  • the present invention relates to a sealed control device for a timepiece housed in a housing comprising a crown rotating around a tube projecting from the housing, said crown comprising a head made of a part, of a on the one hand with a cylindrical central part fixed to a rod capable of occupying at least two axial positions, one neutral pushed in, the other active pulled, and on the other hand with a lateral skirt concentric with said central part and spaced from that -outwardly so as to leave an annular housing between said central part and the internal wall presented by the skirt, said internal wall having a cylindrical surface whose diameter is constant over its entire height, said annular housing being shaped to receive the tube and a gasket compressed between said tube and said inner wall.
  • a device for controlling a timepiece uses a crown which can take at least two axial positions and which can also be rotated manually . If the interior of the timepiece must be waterproof to an external environment composed of dust and water, special measures must be taken to ensure the water resistance of this crown in whatever positions it is located, as well as during its rotation.
  • Figure 1 presents a known solution to the problem posed, a construction used for a long time by the applicant of this document.
  • a tube or pendant 4 is driven into a case middle 5.
  • the crown cooperating with this tube comprises a head 1 made in one piece with a cylindrical central part 9 intended to receive a rod (not shown) in the tapped hole 7 and with a skirt 8.
  • the interior wall of this skirt has a first annular housing 2 of diameter slightly greater than the outside diameter of the tube and a second annular housing 3, of larger diameter, intended to receive a seal. 40.
  • the bottom of the second housing 3 is closed by a ring 6, crimped or driven out, which has the function of holding the lining 40 in place when the crown moves axially along the tube.
  • the construction of Figure 1 has at least two significant drawbacks.
  • the first drawback of this construction is the need to have to change the entire crown during repairs requiring only the change of the single lining, because, due to the presence of the ring 6, the replacement of the lining alone is almost impossible. If this crown is made of gold, as is often the case, it will be understood that throwing it away constitutes a significant loss.
  • the second drawback presented by the construction of FIG. 1 resides in the relative complexity of manufacturing the crown and the internal wall of its skirt which has two different diameters 2 and 3, which requires the use of specialized manufacturers.
  • the present invention provides a sealed control device obeying the generic definition given at the beginning of this description and characterized in that the lining has the form of an annular bandage, the internal part of the bandage having at least one annular projection intended to penetrate into an annular groove presented by the tube, and the external part of the bandage being shaped so that, whatever the axial position of the rod, the lower edge presented by the internal wall of the skirt is always in contact with said external part of the bandage.
  • FIG. 1 is a section through a control device according to the prior art discussed above,
  • FIG. 2 is a section through a device for controlling a timepiece according to the invention, shown in a first thrust position of rest,
  • FIG. 3 is a section similar to that shown in FIG. 2, where the device is in a second pulled working position
  • FIG. 4 is a section similar to that shown in FIG. 2, where the device is in a third pulled working position and,
  • FIG. 5 is an enlargement of a portion of FIG. 4 showing a seal produced differently from that presented in FIGS. 2 to 4.
  • the sealed control device of the timepiece is housed in a housing 20 which may be the middle part of this housing.
  • the device comprises a crown 46 comprising a head 10 made in one piece, on the one hand with a cylindrical central part 23 fixed to a rod 22 and on the other hand with a lateral skirt 12 concentric with said central part 23 and spaced apart the latter towards the outside so as to leave an annular housing 28 between said central part 23 and the internal wall 11 which has the skirt 12.
  • the crown 46 is capable of rotating around a tube 21 projecting from the housing 20 and hunted in the latter.
  • the internal wall 11 of the skirt 12 has a cylindrical surface whose diameter is constant over the entire height of this wall.
  • the annular housing 28 is arranged to receive the tube 21 and a seal 13 compressed between the tube 21 and the wall 11.
  • the lining 13 has the form of an annular bandage, the internal part of this bandage having at least one annular projection 16 which penetrates into a annular groove 15 presented by the tube 21.
  • a no less essential characteristic of the invention consists in shaping the external part 17 of the bandage 13 so that, whatever the axial position of the rod 22, the lower edge 24 presented by the skirt 12 is always in contact with said external part of the bandage.
  • FIG. 2 is the neutral position, depressed, that for which no display correction is possible. If it is a mechanical part, this position could be that of reassembly.
  • Figure 3 is the first position taken from the crown, that for which it is possible to correct the time of the timepiece (or the date according to the caliber and in this case, the crown can be put in a second position pulled).
  • Figure 3 shows that in this position, the lower edge 24 of the skirt is in contact with the outer part 17 of the bandage which is located in the middle thereof.
  • Figure 4 is the second position taken from the crown, that for which it is possible for example to correct the time of the timepiece, this piece also comprising a date display.
  • Figure 4 shows that, in this position, the lower edge 24 of the skirt is in contact with the outer part 17 of the bandage which is located at the top thereof.
  • the lower edge 24 of the skirt is continuously in contact with the lining 13 whatever the axial position of the crown and therefore, it is clear that the internal wall 11 of the skirt remains clean and does not can't be soiled by agents external to the timepiece, which gives the packing a significantly increased service life.
  • a preferred embodiment consists in giving the external part 17 of the bandage 13 the shape of a cylinder whose height is substantially equal to the height of the cylindrical internal wall 11 of the skirt 12.
  • the clearance 14 provides two more marked pressure zones between the lining and the internal wall of the skirt, namely a first pressure zone situated towards the top of the tube and a second pressure zone situated towards the bottom of the tube, the first zone with the primary purpose of the proper seal and the second zone with the primary purpose of keeping the skirt free of all dirt.
  • Figures 2 to 4 also show that a chamfer 27 is formed in an extension 45 of the skirt 12, an extension located beyond the lower edge 24 of the cylindrical wall 11 of the skirt.
  • the purpose of this chamfer is obviously not to damage the lining 13 by an edge which could be sharp.
  • the tube 21 includes a collar 19 which aims to position the tube exactly relative to the housing 20.
  • the diameter of the collar is slightly less than the diameter the cylindrical internal wall 11 of the skirt 12 and that the bandage 13 extends from the upper face of the collar 19 to the upper edge 18 of the tube 21. This arrangement allows better seating of the bandage on the tube.
  • the crown 46 is easy to manufacture, since it has on the inside only a smooth and cylindrical wall.
  • the manufacturing difficulties are reported here on the tube 21, difficulties which in reality are not, since this is a simple external turning commonly encountered in machining mechanics.
  • FIGS. 2 to 5 it can be seen that the annular projection 16 of the lining 13 is located in the middle of this lining, so that said lining has symmetry with respect to a plane perpendicular to the plane of the figures and passing through the middle of the protrusion.
  • This arrangement is advantageous because it allows the fitting to be mounted on the tube without worrying about the mounting direction.
  • Figures 3, 4 and 5 show that the lining 13 is uncovered when the device is in the pulled position, thus making the seal visible to the wearer of the timepiece.
  • This feature which has always been felt to be a drawback, is used here to indicate to the user that the crown is in an abnormal position where time or date corrections could be made untimely, thus prompting the user to push the crown back to the neutral position.
  • This abnormal position could be made even more visible by coloring the trim with a conspicuous color (red or yellow, for example).
