Definitions

• the present invention relates to a wristwatch in which not only is the watch reversible and / or interchangeable as has already been proposed but where the strap itself is reversible and / or interchangeable, these aims being obtained by a system and a simple mechanism easy to manufacture and above all very easy to use for the user.
• the watch according to the present invention is distinguished by the fact that the watch case has, on two opposite sides, at least one male or female coupling member intended to cooperate with at least one female respectively male coupling member of fixed parts. at each of the ends of the bracelet.
• Figure 1 is a perspective view of the bra ⁇ celet watch, the strap being closed in the use or wearing position of the watch.

• Figure 3 is a section along line III - III of Figure 2.
• FIG. 4 is a perspective view of the brace ⁇ let watch, one of the ends of the bracelet being decoupled from the watch case, for example to turn it over on itself.
• Figure 5 is a section illustrating a second form of e- execution of the coupling device between one end of the bracelet and the watch case.
• Figure 6 illustrates in section a third embodiment of the coupling device.
• FIG. 7 partially illustrates the watch case seen from the side comprising the part of the mechanical coupling.
• the illutr ⁇ e wristwatch in FIGS. 1 to 4 comprises a watch box 1 enclosing a watch movement, revealing a dial 2 and emerging on the side a winder 3.
• This watch box is provided on two opposite sides, generally those corresponding to six o'clock and noon from a horn 4.
• the strap 5 of the watch is provided at each of these ends with a coupling piece 6.
• This strap can be made of leather, plastic, metal, steel-gold or bimetal. It can consist of mail ⁇ lons, part of which can be removable for lengthening the brace ⁇ let.
• Each horn 4 of the watch case contains a male coupling element formed by a cylindrical groove 7 surrounding a stud 8 which emerges therefrom axially.
• the free end 9 of this stud 8 has a rounded or generally conical shape.
• This stud has a retaining formation constituted here by an annular groove 10.
• This stud 8 constitutes a male coupling member carried by each horn 4 of the watch case 1.
• Each of these male coupling members is intended to co ⁇ operate with a corresponding female coupling member, fixed to one of the ends of the bracelet 5.
• the part 6, which in the illustrated example comprises an open longitudinal groove 11 allowing it to be fixed to the end of a bracelet by any known means, bar, pin, screw, etc. has a tubular section part 12 in which a slide 13 slides.
• One end of the tubular section part 12 is closed by a plug 14 serving to support a spring 15 acting on the end of the slider 13 located in the tubular section 12.
• the free end 16 of the slider 13, emerging from the part 6 has a shape generally similar or identical to that of the plug 14.
• This coulis ⁇ bucket has a countersink 17 crossed by a pin 18, the ends of which are fixed in two opposite walls of the part 6, it is threaded through the slot 11. This pin 18 cooperating with the countersink 17 of the slide 13 limits the axial displacements of the latter.
• the slide 13 also includes a housing 19 located in the extension of a cylindrical skirt 20 integral with the wall of the part 6 and whose internal and external diameters correspond to those of the cylindrical groove 7 in order to be able to penetrate therein.
• the slide 13 also has a spout 21, having a bevelled side face, intended to cooperate with the circular groove 10 of the stud 8 in the coupled position of the part 6 to the horn 4 of the watch case.
• the user can by simple introduction of the stud 8 in the skirt 20 and by pushing the watch case 1 against the part 6 of the brace ⁇ let couple these two elements. To separate them, it suffices for the user to push on the end 16 of the slide 13 causing the release of the stud 8 the spout 21 coming out of the circular groove 10.
• the strap of this wristwatch is therefore removable since it can be uncoupled at each of its ends from the box. ontre. It is reversible, to do this it suffices to decouple one of its ends from the box, to rotate the other end of the bracelet by 180 ° around the stud 8 then to couple the first end of the bracelet again to the box. watch.
• the strap is also removable, it can indeed be completely disconnected from the watch case and be replaced by another strap comprising parts 6 at each of its ends. .
• part 6 is provided for a bimetal, steel-gold bracelet; White gold; yellow gold or platinum and gold, that is why it comprises an inner tubular element of steel 22 covered with an upper part 23 in one material and with a lower part 24 in another material, these parts 23.24 being united with each other.
• the longitudinal slot 11 contains an open cylindrical part made of steel 25.
• This part 6 is particularly designed to be coupled to a bracelet also bimetal or having two faces of different appearance corresponding to the part 23 and the other at room 24.
• FIG. 4 schematically illustrates the wristwatch in a position where one of the sides of the strap 5 is disconnected from the watch case 1 allowing the strap to pivot relative to the box.
• various means can be provided such as gentle friction between the stud 8 and the skirt 20 or between the latter and the horn 4 of the box; hollow and protruding formations corres ⁇ laying on the part 6 around the skirt 20 respectively on the free edge of the horn 4 or on the flat face of the head 9 of the stud and on the spout 20 for example.
• the shape of the stud 8.9 and of the spout 21 can be modified as long as these parts together allow the production of a mechanical coupling which can be coupled by simple pressure but neces ⁇ siting a voluntary action, the displacement of the slide 13 in the illustrated example, for its separation in order to avoid undesired intem ⁇ pestive separation of the bracelet and the watch case.
• the shape of the part 6, prismatic of square or rectangular section in the example illustrated, could be different, cylindrical of round or oval section, curved along its longitudinal axis or any other determined shape provided with decoration or not.
• the slide 13 could comprise an operating member emerging through a slot made in the wall of the part 6.
• the principle of the present invention lies in the fact of having a bracelet without clasp in the conventional sense of the term, that is to say a continuous bracelet, provided at each of its ends with at least part of a mechanical coupling cooperating with at least a corresponding part attached to the watch case.
• the strap is thus removably attached to each of its ends on one of the two opposed faces of the watch case.
• This principle allows by a simple manipulation of the user, a simple pressure, the removability of the bracelet allowing to use the same bracelet with several different watch cases or vice versa several bracelets with the same watch box. This also allows reversibility not only of the watch but especially also that of the bracelet, or both at the same time. We can therefore consider double-sided bracelets thus multiplying the aesthetic combinations or modes possible for the appearance of the wristwatch.
• the parts 6 are removably attached to the ends of the bracelet to allow the replacement thereof when it is worn while reusing the parts 6.
• these parts 6 can be fixed removably or not at the ends of the bracelet.
• FIG. 5 illustrates a variant of the coupling of one end of the removable and reversible strap to a watch case 1.
• the part 6 comprises, as previously, a slide but is suitable for receiving and locking two integral pins 8, 9 on one side of the watch case.
• the strap thus attached to the watch case is always removable and reversible, but its coupling to the watch case does not allow relative pivoting of these two parts.
• the fixed coupling member, male or nipple 8, 9 could be integral with the parts fixed to the ends of the bra ⁇ celet and cooperate with the movable coupling member allowing the release- rusting by its displacement which would be mounted in two opposite sides of the watch case.
• two opposite sides of the watch case 1 each have a coupling part formed by two studs 9.
• a slot 30 is made between these studs 9 having, near its bottom, lateral recesses 31 receiving the ends of a leaf spring 32.
• the part of the corresponding coupling intended to be fixed on the end of a bracelet comprises a part 6 as described above comprising two openings 33, corresponding to the pins 9 and two slides 34, 35 each provided with a spout 36 intended for cooperate with a stud 9.
• a spring 37 is placed between these slides 34, 35 and tends to move them away from one another, in a position for closing the coupling.
• Each slide 34, 35 has a displacement stroke limited by a countersink 38 cooperating with a pin 39 and has a free end 40 emerging from the part 6 constituting a pusher.
• the part 6 has a tongue 41 on its face directed towards the watch case 1 intended to engage, against the action of the leaf spring 32 in the slot 30.
• This coupling device has two important advantages, on the one hand to open it, the two sliders 34, 35 must be actuated simultaneously, which excludes inadvertent opening, for example under the action of a shock, and, on the other hand when the two slides are actuated simultaneously, the separation of the two parts of the coupling takes place almost automatically by the action of the leaf spring 32 on the tongue 41.
