Definitions

  • the present invention relates to a device and a method for fixing an element of a watch with respect to another with an adjustable mutual angular orientation, and more particularly a device and a method of fixing for a watch case having a screwed back whose alignment can be adjusted with respect to a vertical axis 12 o'clock-6 o'clock.
  • the patent document CH699777 proposes an alternative solution for mounting a steerable bottom on a watch case using an adjusting ring acting as an axial stop to define the angular position of the bottom.
  • the ring is screwed to the middle or to the bottom with a predetermined tightening torque, while the bottom is screwed to the middle part by means of threads arranged in the opposite direction, so that the ring can not be driven into position. rotation when the bottom reaches abutment on the middle part.
  • the bottom is screwed directly onto a piece rigidly fixed to the watch case.
  • the document EP1727005 relates to a device for adjustable screw-retained crown, whose angular position of a logo disposed on the front face of the head of a crown can be adjusted relative to the middle part by means of a threaded ring, arranged around a tube driven into the middle, and whose thread external cooperates with that of an inner wall of the side face of the crown head.
  • the rotational locking of this ring relative to the tube allows to adjust the position of the start of the thread, which determines the angular position of the logo in the screwed position.
  • An object of the present invention is therefore to provide a solution for fixing a bottom to a middle watch, and more generally one element of a watch relative to another with an adjustable mutual angular orientation, which is free from known limitations.
  • An advantage of the proposed solution is to know how to easily perform the angular correction as a function of the difference between the thread pitches used, which is predetermined.
  • the angular adjustment of the intermediate element can thus be carried out at one time, and no longer by successive approximations.
  • the figure 1 discloses a preferred embodiment of the invention according to which the elements to be assembled are respectively a bottom 1 and a middle part 2.
  • the invention could also be used for example for a crown or a valve, these examples being given for information but not limiting.
  • the elements to be assembled may also consist of all pieces integral in rotation respectively of the bottom and the middle of a watch.
  • An O-ring 21 is conventionally inserted into an annular groove at the base of the middle part 2, along a lower contact surface of the middle part 24, intended to come into contact with the upper contact surface of the bottom 14 in an assembled position. .
  • the purpose of the O-ring 21 is to guarantee the tightness of the assembly proposed between the bottom 1 and the middle part 2, when the surfaces 14 and 24 are in mutual contact in the assembled position of the bottom 1 on the middle part 2.
  • a first threaded portion 11 is machined on the bottom 1 and a second thread 22 is machined on the middle part 2; the present invention proceeds from the general idea of using an intermediate element 3 provided with threads and / or threads to be screwed simultaneously to the bottom and to the middle, so that the bottom 1 and the middle part 2 are no longer assembled directly to each other.
  • the intermediate element 3 is a ring provided with a third threaded portion 31 on its inner periphery, which cooperates with the first threaded portion 11 of the bottom 1, and a fourth threaded portion 32 on its periphery. inside which cooperates with the second threaded portion 22, which here consists of a tapping of the middle part 2 according to the preferred embodiment illustrated.
  • the second threaded portion 22 is arranged on an inner wall of the middle part 2, so that the diameter of the ring is reduced; according to a variant it would however also be possible to arrange the second threaded portion 22 of the middle part on its outer wall so that this threaded portion cooperates with the internal thread of a ring 3 whose external thread would cooperate with a threaded portion 11 of the bottom 1.
  • a ring will be preferred because it is simple to machine and inexpensive because of very small volume.
  • the ring according to the invention is preferably threaded and threaded over its entire height to simplify its manufacturing process and comprises lower and upper surfaces (references respectively 34 and 33) substantially flat.
  • the figure 2 shows an intermediate element 3 in the form of a ring according to the preferred embodiment described in FIG. figure 1 previous, top view.
  • the third threaded portion 31 and the fourth threaded portion 32 - there can be seen notches which are intended to receive tenons of a gripping tool to facilitate its screwing, arranged on the upper surface 33 of the ring.
  • These first notches 331 are preferably identical to the second notches 13 of the bottom, so that the same tool can be used to screw the ring on the bottom 1 and then the bottom-ring assembly on the middle part 2.
  • the ring corresponding to a preferred embodiment of the intermediate element 3 illustrated in FIG. figure 2 furthermore comprises angular marks 332 intended to facilitate the adjustment operation in order to reorient the bottom correctly with respect to a predetermined axis, such as, for example, the axis 6h-12h.
  • angular marks 34 preferably consist of graduations arranged on the upper face of the ring and may for example be used in cooperation with an index or any form of marker (not shown) arranged on the bottom 1.
  • first notches 331 may be used as angular references; in this case the angular spacing between two adjacent notches should be chosen sufficiently small, such as less than 15 degrees, to provide a granularity to dispense with any other reference to perform the angular adjustment correction of the ring (element intermediate 3) relative to the bottom 1, whose principle is described below.
  • the figure 3 is a diagram illustrating the various sequences used according to the invention for assembling the bottom 1 to the middle part 2.
  • the intermediate element 3 is screwed on, which can take the form of a ring according to a of preferential embodiment, on the bottom 1 by means of the first threaded portion 11, cooperating with the third threaded portion 31 of the intermediate member 3 to the stop.
  • the arrival at the stop corresponds to the moment when the lower surface 34 of the intermediate element 3 comes into contact with the upper contact surface 14 of the bottom 1.
  • a second step B the bottom assembly 1 is screwed together - intermediate element 3 on the middle part 2 by means of the second threaded portion 22, cooperating with the fourth threaded portion 32 of the intermediate element 3, so that the bottom 1 comes into abutment with the middle part 2, this arrival in stop corresponding to the moment when the upper contact surface 14 of the bottom 1 comes into contact with the lower contact surface 23 of the middle part 2, as illustrated in FIG. figure 4 .
  • FIG. 4 shows that the referenced surfaces 14 of the bottom 1, 24 of the middle part 2 and 34 of the intermediate element 3 are then located in the same horizontal plane, while the Figure 4A shows that the logo 15 disposed on the portion 10 of the bottom is oriented at an angle 120 relative to the axis 200 12h-6h of the watch.
  • the figure 4 also highlights, in addition to the elements already described in the context of the figure 1 , the threaded portions 31,32 of the ring (the intermediate element 3) which we see on the one hand that they are arranged in the same direction, so that the screwing operation of the bottom-ring assembly on the middle part 2 can be performed without danger of unscrewing the ring relative to the bottom and secondly that the thread pitch of the third threaded portion 31 is smaller than the thread pitch of the fourth threaded portion 32, which allows to minimize the angular correction of the ring relative to the bottom when necessary.
  • the relative magnitudes of the thread pitches could be reversed but in this case the angle of correction of the ring relative to the bottom (referenced 130 on the Figure 4A ) would always be higher than the previous orientation of the fund (referenced 120 on the Figure 4A ).
  • the invention makes it possible to perform a simple and rapid step of angular correction of the bottom precisely thanks to the fact that the third and fourth threading steps 31, 32 are differentiated. It suffices to unscrew the ring (intermediate element 3) from the bottom 1 of a dependent angle the difference between the threading steps 310 and 320 of the ring (intermediate element 3) and then screw the ring and the bottom 1 back on the middle part 2 to obtain the desired orientation of the bottom 1.
  • Step C of the diagram of the figure 3 is to visualize the angular orientation 120 of the bottom 1 relative to the middle part 2 in the assembled position, illustrated by the Figures 4 and 4A .
  • This step can be facilitated by the presence of angular markers on the middle part (not shown) and / or on the bottom 1; notches 13 of the bottom can also be used for this purpose.
  • the internal diameter of the ring is for example 30 millimeters and the outer diameter 32 millimeters
  • the pitch 310 of the first and second threads 11, 31 is 0.5
  • the pitch 320 of the third and fourth threads 22, 32 is 0.4, that is to say that a complete turn of 360 degrees corresponds respectively to axial displacements of 0.5 and 0.4 millimeters of the ring.
  • the adjustment angle 130 is derived from the orientation angle 120 determined in step C by simply multiplying the pitch ratio.
  • 130 120 * 310/320 and according to a particularly preferred variant, this ratio of preference can be chosen less than 1 ⁇ 2 so that the correction angle is always less than 180 degrees, which results in easy handling if it is done manually.
  • An angle greater than 180 degrees would require a more awkward operation where the amount of twisting of the arm and / or wrist could be uncomfortable.
  • step E unscrew the intermediate element 3 from the bottom 1 on a stroke corresponding angle, which can be facilitated by the angular marks 332 or the notches when they are used as angular references. Once it is in a good position, it must be ensured that the intermediate element 3 remains locked relative to the bottom 1 when the bottom assembly 1-intermediate element 3 is screwed back on the middle part 2.
  • a locking step n is not necessary when sufficient frictional forces are present between the first and second threaded portions 11, 31, that is, when these are substantially greater than the frictional forces acting between the third and fourth threaded portions 22, 32.
  • the blocking step E ' can be achieved for example by pointing electrical laser welding, or by material discharge.
  • FIGS 5 and 5A show the assembly of bottom 1 - middle 2 in final position after the step F of screwing was carried out.
  • the figure 5 sectional view shows the relative axial arrangements of the various constituent elements of the bottom assembly 1-ring (intermediate element 3) - middle 2, with in particular the axial displacement 131 resulting from the intermediate element 3 relative to the bottom 1 corresponding to the value of the adjustment angle 130 of the Figure 4A , ie 0.11 millimeters for the example described, while the Figure 5A shows that the logo 15 disposed on the part 10 of the bottom is now well oriented relative to the axis 200 12h-6h of the watch.
  • the device according to the invention allows a simple and fast correction, by simple unscrewing-screwing operation, of the orientation of the bottom 1 relative to the middle part of a watch 2.
  • This device can easily be replicated to the mutual angular orientation of any constituent elements of a watch requiring a precise position with respect to a given axis.
