Definitions

  • the subject of the present invention is a device for manual control of a watch movement intended to be housed in a box, comprising a rod coupled to said movement and movable in rotation and in translation relative to said movement and a crown comprising a wall defining a housing.
  • cylindrical coaxial with said rod, said crown being detachably fixed to said rod by fixing means comprising a pair of elastic claws fixed to the end of said rod, a pair of notches arranged opposite one of the each other in one of said claws, and a retaining element integral with said crown and elastically clamped by said claws between said notches.
  • the means generally used for many years to allow the movement of the watch to be nested and dislocated in a case with case-back has a so-called "broken" rod, made of two parts which can be connected to each other. other in a removable way.
  • One of these parts has a pair of notched elastic claws and the other has in the vicinity of its end a transverse bead or a transverse pin.
  • One of these parts is fixed to the movement of the watch by the zipper, and it is short enough not to enter the hole in the middle allowing the passage of the rod. This piece therefore does not prevent the disengagement or the interlocking of the watch movement.
  • the other of these two parts is fixed to the crown, for example by means of a thread placed at its end and screwed into a suitable threaded cylinder fixed to the bottom of the central hole of the crown.
  • This latter patent in particular, describes a device in which the crown comprises an open housing on the side of the watch case, and a threaded rod disposed in the center of this housing.
  • An intermediate piece is screwed at one of its ends to this threaded rod and has at its other end a transverse bead. The latter is clamped between notches formed in elastic claws fixed to the part of the rod which is integral with the movement of the watch.
  • the intermediate piece mentioned above can slide in a tube integral with the middle part of the watch.
  • This device therefore has a relatively high number of parts, and the crown has a complicated shape. The cost price of this device is therefore high.
  • the object of the present invention is to propose a device of the same kind as that which has just been described, but which is cheaper than the latter thanks to the fact that it comprises fewer parts and that, in addition, none of these pieces do have a complicated shape.
  • the control device comprises a crown 1, the body 2 of which, outside the middle part 3 of the case, came from one-piece production with a cylindrical sleeve 5 and has a cylindrical housing 4.
  • a pin 6 is housed in a hole 11 drilled in the body 2 of the crown 1, and passes diametrically through the housing 4.
  • the outer surface 7 of the sleeve 5 is carefully polished so as to slide and rotate freely in a bore 8, drilled through the wall of the middle part 3.
  • a sealing gasket 9, of toroidal shape which is housed in an annular groove 10 of the middle part 3.
  • the crown is solid, for example in however, it will naturally be necessary to ensure that the hole 11, drilled through the wall of its body 2, is perfectly closed by the pin 6, to prevent infiltration between these two parts.
  • the crown 1 is made of base metal, it can be covered with a thin cap, for example made of stainless steel, to close the passage of the pin 6 through the wall of the body 2. In such a case, the pin 6 must of course be put in place before this cap.
  • a rod 13 is mounted in the usual way in movement 12. It is retained in the latter by a stud zipper (not shown), which plunges into a groove 14 of the rod 13. The end of the latter which is external to the movement 12 has a thread 15. An end piece 16 is screwed fully onto this thread 15, so as to be integral with the rod 13.
  • the end of the rod 13 is smooth and the endpiece 16 is driven out and glued to this end so that it is also integral with this rod 13.
  • the outer surface 17 of the nozzle 16 is cylindrical. It engages freely in the sleeve 5.
  • the outer surface 18 of the end of the endpiece 16 is conical and has a diametrical slot 19, so as to form two elastic claws 20. These claws 20 each have a notch 21. These notches 21 partially surround the pin 6 and hold it between them, so that the crown 1 is mechanically connected to the rod 13 and that the latter is driven by any rotational or translational movement printed on the crown 1.
  • the endpiece 16, integral with the rod 13, extends to the outside of the middle part 3, the movement 12, provided with the rod 13 furnished with the endpiece 16, can be fitted without difficulty. Given the absence of a tube in the bore 8 of the middle part 3, the end piece 16, in fact, passes through the hole 8 when the movement 12 is presented in an inclined position relative to the middle part 3. The disengagement operates by leaving the box first of all the part of the movement 12 which is diametrically opposite the rod 13.
  • the pin 6 then forces the spacing of the claws 20, which allow it to pass between them.
  • the taper of the surfaces 18 of the claws 20 allows them to move inside the body 2.
  • the pin 6 thus reaches the notches 21.
  • the elasticity of the claws 20 then causes the latter to come together which consequently trap the pin 6 in the notches 21.
  • a chamfer 22 is provided along the internal edge of each of these claws 20.
  • the crown must first be removed. To this end, it is moved away from the middle part 3 with a force sufficient to iron the pin 6 between the claws 20, moving them apart from one another.
  • the elasticity of the claws 20 must obviously be determined according to the characteristics of the various parts of the movement 12 which are connected to the rod 13, so that the force necessary to tear off the crown is greater than that which must be exerted to bring the crown 1 from its pushed position to its pulled position or positions, but less than that which these various parts of the movement 12 can bear without damage.
  • the second embodiment of the device according to the invention differs from the first only by the fact that the part 23, which replaces the end piece 16 of the first embodiment, has come here in one piece with rod 24.
  • the rod 24 therefore leaves production at a determined length.
  • the length of the rod depending on the dimensions of the box called to receive the movement, it is necessary to adapt to it the length of the rod. To allow such an adaptation, it suffices to provide the fairly long part 23, the sufficiently deep slot 19 and a row of notches 21 along this slot.
  • the pin 6 could also be through the sleeve 5, in a place thereof which, at least when the crown 1 is in the pushed position, is located beyond the seal 9 towards the inside of the box. This avoids any sealing problem which could arise if the pin 6 did not completely block the hole 11 in which it is placed.
  • the sleeve 5 is strong enough to withstand the forces exerted on the pin 6 during the installation or removal of the crown 1.
  • the crown is much simpler than in known devices since it has only a central cylindrical housing and a pin arranged diametrically in this housing.
  • the part of the rod which is integral with the crown in known devices and its means of attachment to this crown are therefore eliminated.
  • the integral part of the rod which carries the notched claws, may have been manufactured in one piece with the rod (claim 2). It can also consist of an independent part, screwed to the end of the rod (claim 3) or driven out and glued to this end of the rod (claim 4).
  • the special embodiments defined by claim 5 have the additional advantage of substituting the crown sleeve for the tube generally fixed to the case in waterproof watches.
  • the space around the rod in the hole in the case, which is free in the absence of the crown, allows the movement to be nested and dislodged from the glass side of a case with case back. The movement can, in fact, be placed in an oblique position at the entrance to this back-middle.
  • this rod through the wall of the middle part can be sealed by a seal fitted in a housing of the middle part so as to encircle the sleeve of the crown (claim 6).
  • the pin gripped by the notches of the claws integral with the rod it can be planted through the sleeve of the crown, beyond the seal, towards the inside of the box, if a leak is to be fear between this pin and the wall of the crown (claim 7).
  • several notches can be provided in fairly long claws (claim 8). If necessary, the ends of these claws can be removed.
  • control device described is particularly advantageous in the case where the movement of the watch is intended to be mounted in a box with case back, of course, nothing prevents its use in the case where the movement of the watch is intended to be mounted in a box with independent bottom.
