Definitions

  • the present invention relates to the field of watchmaking or jewelry. It relates more specifically to a device for attaching a bracelet to an object, in particular a watch case.
  • bracelets made of leather or metal, are attached to the lugs of a watch case, by means of a bar formed of a tube, in which are mounted two pistons movable in translation, and an elastic member disposed between said pistons and tending to drive them out of the tube.
  • Said bar is mounted in a housing provided for this purpose at one end of the bracelet, and the pistons are engaged in blind bores made facing each other in the lugs of the case.
  • Such devices usually comprise a bar, of the type described above, on which is mounted, passing through the tube, a piston actuating member.
  • Said actuating member is, for example, a radial finger integral with one of the pistons, as described in the patent CH 327 838 . The finger is up sliding through an axial slot made in the tube, and its movement along the slot allows one of the pistons to be pushed back inside the tube.
  • the patent CH 614 589 describes a watch case with a device for attaching a bracelet to the case, the central horn has a cylindrical passage split longitudinally over the entire length of the horn, allowing the introduction of a bar for attaching a bracelet .
  • the bar is in the form of a cylinder with a flat along its entire length so as to allow the bar to pass when it is introduced into the passage and to hold it in place when the latter occupies a determined angular position.
  • the fixing devices thus described are generally used for interchangeable bracelets, which they allow to be replaced at the discretion of the wearer. However, they are not without drawbacks. It will be noted, in particular, that they require major structural modifications at the level of the bar, such as, for example, the making of an opening at the level of the tube, or the transformation of the pistons. These changes lead to significant additional manufacturing costs.
  • These fastening devices also comprise a prominent element, namely the actuating member, which can catch on or injure the wearer of the watch.
  • the present invention makes it possible to overcome these drawbacks, by proposing a device for attaching a strap to a watch case, the device comprising said watch case and said strap, said strap being secured to the watch case by means of at least one central horn, and on the other hand at least one insert secured to the end of a bracelet, the insert having a recess of shape complementary to the horn to cooperate by interlocking by constituting removable assembly means capable of to make the bracelet interchangeable.
  • the insert comprises at least one movable pivot mounted in the insert and partially projecting into the recess of the insert, the movable pivot being arranged to engage in a corresponding hole of the horn, and the device comprises manipulation means integral with the movable pivot so as to pass from a first position, called manipulation position, in which the pivot is free to move and the strand can be mounted and/or dismounted, towards a second position, said rest position, in which the pivot is immobile in translation and the bracelet strand is locked on the watch case.
  • manipulation position in which the pivot is free to move and the strand can be mounted and/or dismounted
  • the figure 1 illustrates a wristwatch as well as detailed views of the device for attaching the wristband to the watchcase 1 according to a preferred embodiment of the invention.
  • the device for fixing the bracelet strand 2 to the watch case 1 comprises on the one hand a horn 10 secured to the watch case 10 by means of at least one horn secured to the case, and on the other hand an insert 20 secured to the end of the bracelet strand 2, the horn 10 and the insert 20 being complementary to cooperate by interlocking or clipping one into the other by constituting removable assembly means capable of making the bracelet interchangeable.
  • the insert 20 comprises at least one movable pivot 23 mounted in a passage formed in the insert 20, the passage being close to the free end of the insert.
  • the pivot 23 is partially projecting in a recess 3 of the insert, the movable pivot 23 being arranged to engage in a corresponding hole 11 of the horn 10.
  • the device according to the invention comprises manipulation means integral with the movable pivot 23 so as to pass from a first position, called manipulation position, in which said pivot 23 is free to move and the strand 2 can be mounted and/ or disassembled, to a second position, called the rest position, in which said pivot 23 is immobile in translation and the bracelet strand is locked on the watch case.
  • the watch case 1 comprises a central lug 10 comprising a hole 11 on either side and whose diameter corresponds to the diameter of the pivot 23 so that the latter can rotate freely in the hole.
  • the middle horn comprises a slope 12 guiding the pivot to the hole 11.
  • the insert 20 comprises at least one pivot, the pivot being constrained by return means 4 such as a helical spring.
  • the insert 20 comprises two movable pivots arranged on either side so that each of the pivots opens into the recess 3 of the insert 20.
  • the recess 3 is in U shape, of course the latter can adopt any other type of shape, such as a parallelepiped, hemispherical or even elliptical shape, to adapt to the shape of the horn of the watch case.
  • the insert 20 can equally well be made of metal or metal alloy, of technical ceramic, of composite material or even of plastic material according to the needs of those skilled in the art.
  • the handling means are arranged to pivot from a rest position to a handling position, and comprise a cylindrical body 21 and a handling fin 22 secured to the cylindrical body 21, the cylindrical body 21 being housed in a passage formed in the insert 20 and the fin 22 resting against the edge of the insert 20 to be able to manipulate the means manually.
  • the manipulation fin 22 is parallel to the insert 20 in the rest position, and is perpendicular to the insert 20 in the manipulation position, the manipulation fin 22 passing from one position to the other via a 90 degree rotation. Such an angle of rotation makes it possible to easily manipulate the fin 22 using the fingers.
  • the insert 20 comprises at least one ball catch 6 arranged to cooperate with an orifice 220 of the manipulation fin 22 and lock the latter in the rest position when the watch is worn or the bracelet is not used.
  • the cylindrical body 21 is hollow and is arranged to receive a movable pivot 23, the pivot 23 being able to pivot freely within the cylindrical body 21.
  • the cylindrical body 21 successively comprises a first bore 24 of a first diameter D1, a second bore 25 of a diameter D2, and a third bore 26 of a diameter D3, the diameters D1 and D3 being greater than the diameter D2.
  • the three bores form a through hole with a reduction in diameter in the center.
  • the movable pivot 23 comprises a rod 231 and a head 230, the rod 231 having a diameter slightly smaller than the diameter D2 and successively passing through the third, second and first bores 26, 25, 24.
  • the head 230 has a diameter slightly smaller than the diameter D3 so as to rest in the third bore 26 and against the second bore 25 which acts as an abutment for the head 230.
  • the pivot 23 is inserted into the handling means by the third bore 26 until it stops.
  • the head 230 of the pivot is flush with the surface of the fin 22, so as to make the device as discreet as possible.
  • the first bore 24 is arranged to receive the return means 4, the return means 4 being mounted around the rod 231 and held in the first bore 24 by means of a key 5.
  • the key 5 is mounted on the pivot rod so as to compress the return means and hold the head 230 of the pivot in the third bore 26.
  • the key 5 has dimensions smaller than the diameter D1 of the first bore 24 so as to be able to enter the first bore 24 when the pivot is compressed.
  • the pivot bears against the slope 12 of the horn 10, which has the effect of pushing on the rod 231 and of compressing the spring 4 until the rod enters the hole 11, the pivot then resuming its rest position following the return effect of the spring 4.
  • Such an assembly makes it possible, on the one hand, to maintain the pivot in position when it is inserted into the hole 11 thanks to the return means, and on the other hand to be able to take it out of the hole 10 if necessary via the handling means thanks to the head 230 which is supported against the second bore 25.
  • the person skilled in the art could also consider replacing the assembly formed by the rod and key by a screw screwed into the head 230 of the pivot 23.
  • the fixing device also comprises means for holding and locking the handling means.
  • These holding and locking means comprise a pin 27 mounted in the insert perpendicular to the direction of the bracelet strand.
  • This pin 27 is arranged to cooperate with a peripheral groove 28 formed on the outside of the cylindrical body 21, close to the fin, so as to maintain the handling means in the insert, the pin 27 and the groove 28 forming axial retaining means.
  • the cylindrical body 21 comprises, in the immediate vicinity of the peripheral groove 28, a flat 29 so that the cylindrical body can be moved in translation when the flat and the pin are aligned.
  • the flat 29 is positioned angularly on the cylindrical body so that the flat and the pin are aligned following a rotation of the handling element to bring it into the handling position.
  • the wearer of the watch rotates the handling fin 22 from its rest position to its handling position by rotating 90 degrees, this rotation has the effect of positioning the flat 29 facing the pin 27.
  • the wearer can then pull on the fin 22 to move the latter in translation and bring out the rod 231 of the pivot 23 from the hole 11 of the horn, and then disengage the bracelet from the horn.
  • the wearer retracts the fin 22 by pressing on it until it is in contact with the insert 20 and rotates it again so as to place it parallel to the insert 20 and lock it in position using the ball pawl 6.
  • the insert is connected to a bracelet strand 2 which can be made of leather, synthetic fabric, plastic, metal, ceramic or even composite.
  • a device for fixing a reliable strap enabling the strap to be changed easily and quickly.
