Definitions

  • the present invention relates to a watch case comprising a device for attaching to a bracelet, and more particularly such a watch case for a quick change of the bracelet.
  • Document EP 1 128 237 discloses a watch case comprising horns whose internal lateral face has a groove opening on the underside of these horns, a groove into which a corresponding rib of a fixed intermediate element can engage. at one end of a bracelet.
  • a flap is pivotally mounted in the intermediate element about an axis transverse to the bracelet and is subjected to an elastic action.
  • the flap has a spout which, in the operating position, is applied by the elastic action against an end locking face of the box to hold the end of the bracelet attached to the box.
  • To separate the end of the bracelet from the box it is sufficient for the user to rotate the flap against the elastic action and then to slide the intermediate element relative to the box to disengage the horns.
  • This device is reliable and easy to use, but it requires to provide an intermediate element at each end of the bracelet.
  • the present invention aims to remedy this drawback and proposes for this purpose a watch case according to the appended claim 1, particular embodiments being defined in the dependent claims.
  • the present invention also provides a wristwatch comprising the aforesaid watch case.
  • the watch case comprises a middle 1 for receiving the movement and carrying a mirror (not shown) on its upper face, and a bottom 2 screwed under the middle 1.
  • These two ends of the caseband 1 each further comprise a housing 5a, respectively 5b, machined in the horns 3a, respectively 3b, and in the wall of the caseband 1, between the horns 3a, respectively 3b.
  • This housing 5a, 5b is open on the lower face of the middle part 1, on the edge of the middle part between the horns 3a, 3b and on the faces internal sides facing each other horns 3a, 3b.
  • a movable part 6a, 6b which will be called in the following "lock", substantially of the same shape as the housing 5a, 5b, that is to say having an arcuate portion 7a, 7b of the same radius as the periphery of the middle part 1 and at the ends of which a pair of horns 8a, 8b protrude.
  • the two locks 6a, 6b are movable in translation in the plane of the box, more particularly along the axis 6h-12h of the box, and are maintained in their housing 5a, 5b by the bottom 2 which covers them in part.
  • These two latches 6a, 6b further include a button 9a, 9b projecting on their underside and located in a clearance 10a, 10b formed in one end of the bottom 2. This button 9a, 9b, integral with the rest of the lock 6a, 6b , allows the user to enter the lock 6a, 6b to facilitate the movement of the latter to the center of the box.
  • a leaf spring 11a, 11b is interposed, without being fixed, between the wall of the middle part 1 and the face 12a, 12b of each latch 6a, 6b facing the center of the box (see Figures 1 and 3).
  • the central portion of the leaf spring 11a, 11b is housed in a housing 13a, 13b machined in the wall of the middle part 1.
  • This leaf spring 11a, 11b is permanently stretched by the wall of the middle part 1 exerting a pressure on the central portion of a first face of the leaf spring facing the center of the box and the face 12a, 12b of the lock 6a, 6b exerting pressure on the two ends of a second face of the blade- spring opposite to the first face.
  • each latch 6a, 6b serves as stops limiting the possible lateral movements of each leaf spring 11a, 11b.
  • Each leaf spring 11a, 11b has a pair of chamfers 15a, 15b at the ends of its upper edge to facilitate its implementation (see Figure 5).
  • each leaf-spring 11a, 11b tends to maintain the corresponding lock 6a, 6b in a locking position where the lock 6a, 6b, more precisely the horns 8a, 8b, abut against walls of end 16a, 16b of the pair of horns 3a, 3b corresponding (see half left of Figure 3).
  • the user can, using the button 9a, 9b, move the latch 6a, 6b towards the center of the box against the aforementioned elastic action to a position the spring blade 11a, 11b is pressed by the latch 6a, 6b against the wall of the middle part 1 and a space is released between each horn 8a, 8b and the corresponding end wall 16a, 16b (see FIG. right half of Figure 3).
  • the leaf spring 11a, 11b expands and returns the lock 6a, 6b to its locking position.
  • each horn 8a, 8b of the locks 6a, 6b has in the upper part a notch 17a, 17b ( Figures 1 and 4b).
  • Each notch 17a, 17b is complementary to a corresponding recess 18a, 18b formed in the bottom of the housing 5a, 5b, in the corresponding horn 3a, 3b of the middle part 1, and near the end wall 16a, 16b of this horn 3a, 3b (only one recess 18a, 18b is visible in Figure 1 for each pair of horns 3a, 3b).
  • These recesses 18a, 18b are in the form of blind half-holes open on the lower face of the box and on the internal lateral face of the horns 3a, 3b.
  • the user To attach a strand 4a, 4b of the bracelet to the box, the user introduces the ends of the bar 19a, 19b into the recesses 18a, 18b perpendicularly to the plane of the box and from below the box. To do this, the user does not need to act on the button 9a, 9b.
  • the free ends of the horns 8a, 8b of the locks 6a, 6b each have, in the lower part, a rounded surface 20a, 20b opposite the end wall 16a, 16b of the horn 3a, 3b corresponding to the middle part 1 ( Figures 1, 6).
  • the user will exert by the ends of the bar 19a, 19b a bearing force on the two rounded surfaces 20a , 20b of the lock 6a, 6b until the latter moves back by compressing the spring blade 11a, 11b thereby uncovering the lower opening of the recesses 18a, 18b and thus allowing the insertion of said ends into the recesses 18a, 18b , as shown in FIG. 6.
  • the spring blade 11a, 11b instantly returns the latch 6a, 6b to its locking position, trapping said ends in the cavities formed by the notches 17a, 17b and the recesses 18a, 18b.
  • the user grasps the corresponding lock 6a, 6b by the button 9a, 9b and moves it towards the center of the box until the ends of the bar 19a, 19b and the recesses 18a, 18b are no longer covered by the horns 8a, 8b of the lock 6a, 6b (unlocking position).
  • the lock 6a, 6b disengages the bar 19a, 19b from the horns 3a, 3b by sliding it perpendicularly to the plane of the box between the free ends of the horns 8a, 8b of the lock 6a, 6b and the end walls 16a, 16b of the horns 3a, 3b of the caseband 1.
  • the user can simply push this button 9a, 9b with the thumbnail of the hand holding the bracelet strand 4a, 4b.
  • the user can rotate the bracelet strand 4a, 4b under the watch case so that this bracelet strand 4a, 4b acts as a lever arm actuating the button 9a, 9b.
  • the watch case according to the invention further comprises a safety device comprising a groove 21a, 21b made in the internal lateral face of each horn 3a, 3b of the middle 1 and opening into the housing 5a, 5b and a corresponding lug 22a, 22b formed at the free end of each horn 8a, 8b locks 6a, 6b ( Figures 1 and 4b).
  • a safety device comprising a groove 21a, 21b made in the internal lateral face of each horn 3a, 3b of the middle 1 and opening into the housing 5a, 5b and a corresponding lug 22a, 22b formed at the free end of each horn 8a, 8b locks 6a, 6b ( Figures 1 and 4b).
  • the lugs 22a, 22b enter the grooves 21a, 21b respectively so that in the locking position the lugs 22a, 22b are retained in the direction perpendicular to the plane of the box by bearing faces 23a, 23b defined by the grooves 21a, 21b.
  • This safety device aims to prevent accidental detachment of the bracelet 4a-4b and a possible destruction of the locks 6a, 6b during a strong draw of the bracelet 4a-4b towards the underside of the watch.
  • the lugs 22a, 22b are not in the grooves 21a, 21b, which allows the locks 6a, 6b to be easily removed from the housing 5a, 5b during disassembly of the box in sight for example of its cleaning.
  • the present invention as described above has many advantages. It will be observed in particular that it does not require a specific intermediate piece between the ends of the bracelet and the box and allows on the contrary attachment to the standard box of bracelets, leather, synthetic material or metal for example, simply equipped with strips. As the bars of the bracelet do not need to be provided with a spring, they can be monobloc, simple and robust. Moreover, the risks of scratching the caseband during the fixing of the bracelet, risks that exist with conventional watch cases requiring the use of spring bars, are here eliminated. It will generally be noted that the fastening device of the wristband of the watch case according to the invention is simple, aesthetically discrete, safe (reduced risk of accidental opening) and allows a quick and tool-free change of the wristband.
  • the present invention is not limited to the embodiment described above and that modifications may be made without departing from the scope of the claimed invention.
  • the recesses 18a, 18b could have a shape and a size adapted to fully receive said ends.
  • the notches 17a, 17b formed on the horns 8a, 8b of the locks 6a, 6b would be removed.
  • the bars 19a, 19b fitted to the ends of the bracelet 4a-4b could each be replaced by two opposite lugs protruding from the longitudinal edges of the bracelet, lugs that could be attached or in one piece with the ends of the bracelet .
  • the locks 6a, 6b could be mounted movable in a plane at an angle with the plane of the box, for example a plane slightly inclined relative to the plane of the box.
  • each end 4a, 4b of the bracelet could comprise a notch uncovering a central portion of the bar 19a, 19b
  • each latch 6a, 6b could comprise, in place of the horns 8a, 8b, a central leg coming to cover the central part of the bar 19a, 19b in the locking position to maintain this bar in the recesses 18a, 18b of the horns 3a, 3b of the middle part 1.
  • each pair of horns 3a, 3b of the middle part 1 could be replaced by a central fastening tab having an open recess on the underside and on both side faces of the tab, and each end of the bracelet could comprise a notch uncovering a central portion of a bar transversely passing through this end, central portion that would be received in the recess of the bracket and trapped, in the locking position, in this recess by a latch covering the lower opening of the bracket.
  • the recesses of the box receiving the attachment means (bar, lugs, etc.) fitted to each end of the bracelet could be open on the upper face of the box rather than on the lower face and the locks could be housed in this upper face so that the insertion of the attachment means in the recesses is effected from above rather than from below the box.
