Definitions

  • the present invention relates to a monocoque wristwatch in which the middle-bezel, the back and the horns which serve to attach the bracelet to the case are made in one piece.
  • the object of the present invention is to simplify the manufacture of the housing as much as possible, to reduce the subsequent machining operations as much as possible and to simplify the mounting operations.
  • the wristwatch of the invention combines a series of very precise characteristics, most of which are known per se, but which, when combined, produce a surprising effect by the very small number of parts involved, by the simplicity of production of these parts, by a single machining operation of its housing and by a time of assembly reduced to the maximum, this while ensuring the object an excellent finish and a general high-end quality.
  • Figure 1 shows in perspective the case 1 of the watch essentially composed of the middle part-bezel 42, two pairs of horns respectively referenced 2, 2 'and 3.3' and a back 43. All these elements are made of one piece. In each horn is made a hole 5 into which one of the ends of a spring bar used to attach the bracelet using a well-known technique.
  • housing 1 In the housing 1 is housed an assembly 44 formed by the elements shown in perspective in FIG. 2. It is a casing circle 18 which receives a movement 25 then a dial 28.
  • Means define the angular position of the circle 18, therefore of the assembly 44, relative to the housing 1.
  • these means consist of a boss 7 formed inside the middle part-bezel 42 (FIG. 1) , boss which cooperates with a housing 19 formed in the circle 18 ( Figure 2).
  • Other means also define the radial position, or the centering of the circle 18 relative to the housing 1.
  • these means consist of a machining carried out in the internal wall 6 of the middle part-bezel 42, machining which makes this wall cylindrical. The diameter of the machining is brought to a dimension suitable for receiving the upper circumference 50 of the circle 18.
  • other means define the axial position of the circle 18 relative to the housing 1.
  • a support shoulder 8 is made in the middle part-bezel 42 (FIG. 1). On this shoulder 8 comes to bear the lower edge 17 of the circle 18 ( Figure 2).
  • the assembly 44 is formed of the circle 18, of the movement 25 and of the dial 28.
  • means are provided for angularly positioning the movement and the dial relative to the circle.
  • FIG. 2 shows that the movement 25 comprises a housing 23 which cooperates with a boss 21 formed inside the circle 18 when the movement is placed in the circle in the direction indicated by the arrow B.
  • the circle has another housing 22, housing in which takes place a first part 35 of a time-setting rod placed inside the movement 25.
  • This folding can be achieved by softening the material, if the circle is made of plastic, and is visible in Figure 4 under the reference 45. Once the folding, the assembly 44 forms a whole which holds together and can be easily handled. Note that to this set we will add needles that we will plant on the output axes 26 of movement 25, as well as a battery (not shown), as will be explained below.
  • the assembly thus formed is introduced into the housing 1 until the lower edge 17 of the circle 18 abuts against the support shoulder 8 taking care to coincide the boss 7 of the housing with the housing 19 of the circle .
  • Figure 4 is a section at 6 o'clock in the fully assembled watch.
  • the horn 2 the bar hole 5 and the housing 1 with its middle-bezel 42.
  • the lower edge 17 of the circle 18 rests on the support shoulder 8 of the middle.
  • the movement 25 comprises a thread 53 which rests on the support shoulder 51 made in the circle 18 and that the dial 28 rests on the support shoulder 52 made in the same circle.
  • the circle 18 is centered radially by the internal wall 6 of the middle part 42 and its upper edge has the fold 45 which serves to fix the dial on the circle.
  • On the dial 28 rests the flange 30 centered by the same internal wall 6.
  • the flange has a recess in which takes place the drawdown 45 and that it rests on the dial by a flange 54.
  • the edge 46 of the glass 32 compresses the lining 31 against the internal wall 6 of the middle part-bezel 42.
  • FIG. 4 like FIGS. 5, 6 and 7, moreover, shows that under the movement 25 is fixed an enclosure 24 comprising a raised edge 41, enclosure in which a battery takes place (not shown).
  • This battery is for example of the large diameter lithium type, which allows a long run time of the watch. It will be noted that to change the battery, the second part 14 is removed from the rod (FIG. 1), then air is blown into the rod hole 13, which drives the ice 32 out of its housing and which allows finally to release movement 25 with its enclosure 24.
  • Figure 5 is a section at 12 o'clock in the fully assembled watch. We distinguish in this drawing the boss 20 forming part of the circle 18 and imposing on the dial 28 a precise angular position relative to the circle. We also distinguish in Figure 5 the boss 7 forming part of the housing 1, a boss which is in place in the housing 19 formed in the circle 18 and which imposes on the circle a precise angular position relative to the housing.
  • Figure 6 is a section at 9 o'clock in the fully assembled watch.
  • the boss 21 which forms part of the circle 18 and which imposes on the movement 25 a precise angular position relative to the circle is distinguished, this boss cooperating with the housing 23.
  • Figure 7 is a section at 3 o'clock in the fully assembled watch.
  • the time-setting rod composed of a first internal part 35 coupled to the movement 25 and a second part 14 crossing the middle 42.
  • This rod is of the broken type.
  • These first and second parts are coupled at 36, as described for example in patent CH-A-524 178.
  • the rod comprises only the first part 35.
  • the second part 14 is introduced into the bore 13 made in the middle in the direction of the arrow A (FIG. 1) and this until the two parts click into place.
  • the rod passes through the housing 22 formed in the circle.
  • FIG. 7 also shows that the second part 14 of the rod is capped by a crown 16, the latter being partially engaged in a housing 12 comprising a roof 37. It will be understood that this arrangement makes it possible to conceal certain inaccuracies over the length of the rod so that the crown base always remains inside the housing 12.
  • the second part 14 of the rod still has a groove 33 occupied by a lining 15 which seals the rod as it passes through the hole 13.
  • this construction in no way requires the use of a tube driven into the middle as is usually seen to ensure this seal.
  • Figure 8 is a section at 9 o'clock showing two variants of execution compared to the execution presented in Figure 6.
  • a first variant consists in bringing together in one piece the flange 30 and the trim 31 of FIG. 6, which results in the single piece 38 shown in FIG. 8.
  • a second variant consists in associating with the circle 18 the battery enclosure 24 shown in FIG. 6.
  • FIG. 8 shows a single part 39 acting as a circle and as a battery enclosure at the same time.
  • FIG. 8 also makes it possible to explain, together with FIG. 9 which shows in detail the internal wall of the case 1, an important and characteristic arrangement of the watch according to the invention.
  • the housing 1 after molding and sintering, has flat horizontal surfaces such as the bottom 10 and the support shoulder 8, and inclined surfaces, allowing demolding, such as the surfaces 9 and 11 (see FIG. 9) .
  • the inclined surface 11 we will grind a cylindrical face 6 which will serve as a centering reference for the circle 39 and for the part 38 assembling the flange and the seal. For this, the grinding depth must be greater than the sum of the heights of the lining, the flange and the circle.
  • the manufacture and assembly of the watch according to the invention are thus extremely simplified:
  • the housing 1, leaving the molding, must undergo only one machining operation: that of the grinding of the internal reference wall 6.
  • the internal face 10 of the base 43, the support shoulder 8 come out of sintering without have to be touched up.
  • the housing 1 has a hole 13 of rod and holes 5 of bracelet bars which also come out of sintering without having to be touched up.
  • the horns 2, 2 'and 3, 3' do not have to be added since they are molded with the housing.
  • the boss 7 can also be left raw.
  • the casing ring 18 made of plastic is injected at once with all its positioning housings and bosses, as well as with its bearing surfaces for the movement and the dial.
  • the assembly 44 formed by the circle 18, the movement 25, the dial 28 and the hands forms a whole that is easy to assemble for itself, for example on an automatic machine and easy to then assemble in the case.
  • the whole watch is mounted on one side and there is no need to turn it over. No fixing screw is used for assembly.
