Definitions

  • the invention relates to a timepiece comprising a rod and pull control mechanism. More particularly, the invention relates to a wristwatch comprising a monocoque box, that is to say having a middle part and a back made in one piece, provided with a device making it possible to act on the pull tab in order to release the control rod which acts on the movement, such as the winding or time-setting rod of the timepiece, to withdraw it longitudinally towards the outside of the case so that the movement can be extracted from the box from above when the ice is removed.
  • the puller pivotally mounted on the movement plate, is subjected to the action of a leaf spring which tends to engage a projection made at one end of the puller in a groove of the control rod, the other end of the pull tab being intended to control a rocker engaged in the groove of a sliding pinion mounted movably on the winding rod.
  • the bottom of the box is generally pierced opposite an appropriate opening made in the movement in the region of the pull tab and is introduced in this opening a tool capable of releasing the puller of the winding stem which allows this stem to be removed.
  • the movement can then be easily extracted from the case from above, in a conventional manner, once the ice has been removed.
  • the box is therefore unusable after this operation. If such a practice has little economic consequence in the case of plastic boxes, the material being able to be easily recycled and its cost being relatively low, it is easily understood that it is different, for obvious reasons of cost , when it comes to intervening on a movement mounted in a monocoque box made of metal.
  • Document CH 558 039 proposes to overcome this problem by providing a watch of the aforementioned type comprising an extractor lever, the free end of which protrudes from the movement and the opposite end of which acts on one end of the pivot axis of the pull tab. so that, when a pressure is exerted on the projecting part of the lever, the axis of the zipper moves longitudinally against the action of a leaf spring and lifts the zipper so that the projection emerges from the groove of the stem. The rod can then be removed from the movement.
  • This construction has the drawback, however, of requiring a particular pull rod axis - longer than a conventional axis - as well as a special mounting of this axis in the frame of the movement so, on the one hand, that it is mobile longitudinally in the frame and, on the other hand, that one of its ends can cooperate with the end of the extractor lever.
  • This construction also requires a free space above the whole zipper so that it can mount.
  • the main object of the invention is therefore to remedy the abovementioned drawbacks of the prior art by providing a timepiece having a box of the monohull type and comprising a rod and pull control mechanism, this timepiece being provided of a simple and economical device which does not require any particular adaptation of the mounting of the zipper on the movement frame and which allows the zipper to be raised to release it from the winding stem without having to pierce the bottom of the case.
  • a device which, once the ice has been removed, makes it possible to slide the extractor element by means of a simple gripping tool, such as pliers, to lift the zipper and release the rod from ordered.
  • this device makes it possible not to modify the construction of the assembly of the zipper in the movement and thus to be able to equip it with movements of conventional construction.
  • the extractor element has a U-shape, the first branch being connected via a central branch to the second branch which extends substantially parallel to the first branch and which comprises a folded portion protruding from the periphery of the movement to form the gripping arm.
  • the extractor element can thus be produced using a simple folded and inexpensive element, such as a wire. Furthermore, given the simplicity of the shape of this element, its mounting on the movement is easy.
  • the bottom of the box comprises a recess in which the central branch extends, the latter resting on the bottom of the recess in the rest position of the extractor element.
  • the extractor element does not require the provision of any particular means for fixing the latter on the movement.
  • this timepiece in the form of a wristwatch.
  • Watch 1 comprises a movement 2, conventionally comprising a plate and bridges (not shown), surmounted by a dial 4 above which display means 6 move.
  • Movement 2 is housed in a box 8 comprising a base 10 and a middle part 12 in one piece.
  • the box is closed by a crystal 14 driven in a conventional manner in a first housing 16 of the middle part 12.
  • the crystal 14 applies a flange 18 against the edge of the dial 4.
  • the crystal 14 is also overcome, in its peripheral part, a decorative telescope 20 driven into a second housing 22 of the middle 12.
  • the watch 1 further comprises a control mechanism 24 which acts on the movement 2.
  • the mechanism 24 makes it possible, for example, to set the time to the watch and its winding in the case of a mechanical watch or, where appropriate, other functions such as resetting a calendar indicator to the date.
  • the mechanism 24 comprises a control rod 26 which passes radially through a bore 28 of the middle part 12 and which is guided therein.
  • the rod 26 comprises a first part 30 which extends outside the box 8 and on which is fixed a crown 32, and a second part 34 which extends in a clearance (not shown) provided for this purpose in movement 2.
  • the part of the rod 26 cooperating with the bore 28 is provided with an annular groove 36 in which a sealing gasket 38 is disposed.
  • the part 24 comprises a groove 40 and a portion with a square cross section 42 intended to cooperate with a square bore of a sliding pinion (not shown).
  • the mechanism 24 further comprises a pull tab 44 (partially shown) pivotally mounted on a frame or a plate of the movement 2.
  • the pull pull 44 has a part provided with a projection 46 which is engaged in the groove 40.
  • This mechanism 24 also includes means such as elastic means which tend to engage the projection 46 in the groove 40.
  • these elastic means can be formed by the pull tab itself as in the present case or by a leaf spring or the like .
  • the watch according to the invention further comprises an extractor device 48 intended to raise the pull tab 44 to release the projection 46 from the groove 40 of the control rod 26 and release it, by actuation of this device from above the shows when the glass 14 is removed and the movement 2 is still fitted into the monocoque box 8.
  • the extractor device comprises a single extractor element 48 which extends partially in a clearance (not shown) of the movement 2 and partially outside of the latter so that it can be accessible for example with a tool such as pliers or the like from the top of the watch.
  • the extractor element 48 is movable between a first so-called rest position, shown in FIG. 1, in which it does not act on the pull tab 44 or in other words it allows the pull tab 44 to be engaged in the groove 40, and a second so-called functional position, represented in FIG. 2, in which the extractor element 48 acts directly or indirectly on the pull tab 44 to push it out of the groove 40 of the control rod 26.
  • the extractor element 48 has the configuration of a "U".
  • This element 48 comprises a first branch 50 and a second branch 52 which extends substantially to the first.
  • the first branch 50 and the second 52 are connected by a central branch 54 which extends substantially perpendicularly to the branches 50 and 52.
  • the first branch 50 slides in movement 2, in a direction substantially perpendicular to the plane of movement 2.
  • the branch 50 actually slides in a clearance 53 (shown schematically in the drawing) of the movement 2 which opens on the one hand into the lower part of the movement 2 and on the other substantially opposite the pull tab 44 so that the end of the branch 50 is also located opposite the pull tab 44, and preferably facing a part of the pull tab 44 which is close to the projection 46.
  • a clearance may, for example, be formed by the clearance normally provided in the conventional movements to insert a tool such as the tip of a screwdriver, in order to release the rod of the pull tab 44.
  • the second branch 52 comprises a portion which projects from the periphery of the movement 2 to form a gripping arm 54. More specifically, the portion 54 is formed by the extreme part or free end of the branch 52 which is folded 90 degrees outward from the "U". In the example illustrated, the branch 52 extends outside of the movement 2, and the gripping arm 55 is housed in a lateral clearance 56 formed in the inner wall 58 of the middle part 12 which surrounds the movement 2.
  • the extractor element 48 is produced by a folded element with constant cross section and in particular by a folded metal wire. Of course, this element 48 could, according to a variant, also be made of plastic, for example by molding.
  • the central branch 54 connecting the branches 50 and 52 extends outside the movement 2 in a recess 60 formed in the bottom 10 of the box 8. More specifically, the branch 54 rests on the bottom 62 of the recess 60 when the extractor element 48 is in its rest position ( Figure 1).
  • the stroke C of the extractor element 48 is determined by the distance separating the bottom 62 of the recess 60 from the lower surface 64 of the movement insofar as the central branch 54 abuts against the lower surface 64 in the functional position (FIG. 2) of the extractor element 48.
  • this stroke C will be determined differently according to an alternative embodiment (not shown) in which the movement 2 comprises, in its lower part, a recess or a notch in which the central branch 54 at least partially extends in the position functional, and if necessary, in the rest position of the extractor element 48.
  • the depth of the recess 60 can be reduced or else the recess 60 can be completely eliminated, the stroke C then being determined by the height of the notch in the part lower movement 2 in which the branch 54 can be housed in the functional position.
  • the procedure is as follows.
  • the telescope 20 and the glass 14 and, where appropriate, the dial 4 are removed in a conventional manner to free access to the lateral clearance 56.
  • a tool such as pliers, is then introduced therein in order to grip the arm 55 and to exert a traction on this arm in the direction of the arrow F.
  • the branch 50 slides in the release of the movement and the end of the branch 50 lifts the pull tab 44 and releases it from the groove 40.
  • the movement 2 can then be extracted without difficulty of the box 8 by conventional means.
  • the extractor element 48 can be mounted just before the casing of the movement 2 and this by simply introducing the branch 50 in the appropriate clearance of the movement 2 and therefore without the need to use any tool .
