Definitions

  • the present invention relates to a watch case according to the preamble to the independent claim 1.
  • CH-654,167 discloses a watch case comprising a part annular 7 in a material whose machining is very difficult. But the means offered do not constitute truly a solution to the problem posed, since certain parts of the said part must still be machined respecting precise dimensions (page 4, column of left, lines 19 and sq.). It’s just this guy machining that the inventor of the present invention wants dismiss.
  • EP-0,150,746 B1 also describes a watch case comprising a middle formed by two concentric rings, either an inner ring, which constitutes the middle proper surrounding the movement, and a ring exterior (or annular piece or decor piece) fulfilling in particular an aesthetic function. But this piece, held between a bottom and a front plate (capping the inner ring, on which it is glued), must have substantially the same thickness as this inner ring. Indeed, it is specified that, if the piece of decoration is separated from the middle by a joint, it is retained in the axial direction only by the effect of nipping between the bottom and the faceplate, no other fixing means not provided.
  • the thickness of the decoration piece must necessarily be machined there too, respecting at least a precise rating. Because either the thickness of the ring exterior decoration is higher than the imposed rating, and the back cannot be tightened properly against the middle (inner ring), which will have extremely harmful to very quickly put the watch out of service, since neither the waterproofing nor the shock absorption will be insured, in addition to the fact that the decoration piece will undergo damage during the mounting of said base on the middle. Or well the thickness of this outer ring is less than the imposed rating, and it will necessarily start move in an axial direction, which over time will cause damage to it, excluding the effect for the less unsightly generated by this degree of freedom not wish.
  • the purpose of the present invention is to overcome these disadvantages.
  • FIG 1 we see the wristwatch which has a movement 10 of axis 10 A carried by a circle 11, this movement being of known type (it can be mechanical, quartz to needle or digital display, etc.), 14 H hands (hour hand) and 14 M (minute hand) driven out respectively on the barrel and the roadway (globally referenced by 14), and a dial 18. All of these elements are housed in a box consisting of middle 20, a back 30 and a watch glass or crystal 40, the latter being made integral with the middle part by means 41.
  • the middle part 20 surrounds by its inner face 22 the movement 10 - circle 11 assembly and includes a beak or notch 27 retaining said dial.
  • the bottom is fixed under the middle, preferably removably, by means fasteners, for example by four screws 19 distributed at 1:30, 4:30, 7:30 and 10:30.
  • a setting rod hour 15 crossing middle 20 is also shown (partially), with its crown 16 (in line mixed end) and a joint 17.
  • the middle part 20 has a lateral face 21, opposite the face 22, these two faces extending parallel to the axis 10 A of the watch case and, opposite the back 30, one side lower plane 25 orthogonal to axis 10 A.
  • the middle has a shoulder 24, including one face 23, preferably parallel on face 25, is oriented towards the latter.
  • the face visible upper part of this shoulder bears the reference 28.
  • the middle can be made in various materials, especially metal, such as steel, yellow gold or white, or a combination of these two types of gold, etc.
  • the face 28 can be provided with decorative elements or jewelry; it can include, for example, a crimp precious or semi-precious stones.
  • the bottom 30 is composed of a preferably flat plate and metallic, delimited by its inner faces 32, outer 33 and lateral 31. It is provided on the sides 6:00 a.m., 12:00 p.m., connecting means 34 to a bracelet so known to those skilled in the art (see Figure 2).
  • annular piece 50 (the shape of the ring before, of course, be understood in the broad sense, in the sense that it is not confined only in circular form).
  • this piece 50 is shaped in a hard and fragile material, therefore difficult to machine, such as glass. It surrounds the middle 20 - what defines its shape, plan view (cf. Figure 2) - and is pinched between it and the bottom 30, in the conditions described below. As for its shape seen in section as shown in the figure, 1, it is defined by the inner faces 51 (arranged opposite the face 21 of the middle part), lower 52, upper 53 and lateral lateral 59 A.
  • the faces 52, 53 are capped partially, respectively by the underside 32 of the bottom and the underside 23 of the shoulder 24 of the middle.
  • the faces 52, 53 are, at the places where they are thus capped, preferably parallel to each other.
  • gaps 56, 58, 57 extend between the faces 51, 21; 53, 23; 52, 32) respectively.
  • part 50 has a bore 55, for the passage of the time-setting rod 15, the diameter of this bore can be very much greater than that of said rod.
  • This bore leads to a notch or groove 59 (of usual and known form, cf. FIG. 2) to allow actuate the crown 16 at the end of the rod 15.
  • the part 50 also cooperates with means 60, 70 to maintain the gaps 56, 58, 57 and, by Therefore, avoid that the decor piece comes into contact with adjacent elements, middle 20 and back 30.
  • these means are dissociated, that is to say composed of first and second means, bearing the references 60 and 70 respectively.
  • the first means 60 advantageously consist of at least minus a compressible annular element arranged in the area the angle formed by the faces 21, 23 of the middle part 20 and the corresponding faces 51, 53 of the part 50. According to the example, they are composed of an O-ring 60 partially seated in a groove 26, this joint being able to when mounting the back 30 on the middle part 20 at by means of the screws 19, a reaction force F 1 by pressing on a chamfer 54 breaking the angle of the faces 51, 53.
  • the dimensions of the means 60 are defined so that a gap 56 between the aforementioned faces 21, 51 and a gap 58 between the sides 23, 53, can be reliably insured especially during said assembly, by not falling below a limit value, for example one tenth of a millimeter, which, moreover, makes it possible to spare the decor piece 50 in all circumstances.
  • the second means 70 are formed, depending on the execution, of an annular or solid part. Section view according to Figure 1, this part is flat (like the bottom 30 on which it is asked). Its shape can be defined geometrically by the exterior, interior and exterior side faces, bearing the references 72, 73 and 71 respectively; in his annular embodiment, part 70 is necessarily further defined by its inner side face, shown symbolically in Figure 1 by the reference 74. These means 70 are made of flexible and compressible material. What whether the execution (flat annular or solid part, we will adopt the same reference 70).
  • the means 70 correspond to the shape full room execution. They are arranged on the face inner 32 of the bottom 30, the outer lateral face 71 being flush with the lateral face 31 of the bottom 30 or (see Figure 1), slightly behind the latter. According to annular embodiment not shown, part 70 should extend under the underside 25 of the crown, the underside 13 of the ring 12 of the circle 11 and partially under the face 52 of the decoration piece 50. That is, the inner side face (shown symbolically by the reference 74) is flush with the face inner (not referenced) of said ring 12 or, for more safety, slightly exceeds limit 74 towards axis 10 A of movement 10.
  • This minimum width of the crown of the annular part (when the annular part variant is chosen) which therefore extends from the faces referenced 71 to 74 (or even a little beyond the latter), is of importance.
  • an object of the invention is to avoid damage (cracks and / or breaks in the decor piece, both during manufacture and during assembly of the background on the middle, lack of waterproofness, deficiency in shock absorption function) which may result from pinch of said part, and even take advantage of the constraint posed by the imprecision in shaping this Exhibit 50.
  • reference dimensions such as, by making abstraction of the means 60, 70, the theoretical difference between the sides 21 and 51 is at least equal to one tenth of millimeter, plus a determined value ⁇ D1 + S1 ⁇ , and that the thickness between the faces 52, 53, measured at the places where these are parallel and capped by the shoulder 24 and the bottom, corresponds to the distance between the planes 23, 25 of the middle, minus a value on the order of a tenth of millimeter, and minus a determined value ⁇ D2 + S2 ⁇ .
  • the values D1, D2 are planned and calculated to be able absorb the effects of differences between the coefficient of expansion of the metal (middle 20 and bottom 30) and that of a mineral element (decoration piece 50), the the first being appreciably larger than the second. It is another great advantage of the layout gaps between the decoration piece 50 and the elements especially adjacent metal.
  • the gaps 56 and 58 are maintained reliably, these means exerting in addition and concomitantly a sealing function and a damping function shocks aimed at preserving the decoration part 50.
  • the means 60 solve part of the problem, they create a new one, namely a possible deficiency of the shock absorption function on the movement 10.
  • the thickness of the piece 50 would correspond to the tolerance maxima and where, on the other hand, coin 70, assuming that it is of the annular type, would extend only under the side 25 and partially under side 52, extended over which the part 70 is compressed under the action of clamping means for fixing the base to the middle, the circle 11 would not be kept or insufficiently held, so that the movement 10 could "float" with each movement of the wrist and suffer all shocks.
  • the part 50 would correspond to the minimum tolerance, the part 70 being otherwise the same, this defect would not be lament; as for room 50, it would be enough held thanks to the play of sufficient compression of the means 70.
  • the means 60, 70 can be monolithic, that is to say that these are connected by a tubular plastic casing semi-rigid, the perimeter seen in plan corresponds to edges of the faces 21, 51.
  • the dimensions of reference of the recess of the decor piece 50 will be such that the latter can be easily slid over said envelope.
