Abstract

The end, or last link, of the strap (20) has a protuberance (21) with two pegs (22,23) projecting from opposite sides on a common axis (27) parallel to the edge (16) of the wrist-watch case (10). When the protuberance is pushed into a recess (11) in the end of the case, both pegs spring into a groove (13), while a threshold (14) across the entrance to the recess engages in a matching slot (24) in the underside of the protuberance behind the two pegs. <IMAGE>

Description

La présente invention a pour objet un dispositif de fixation et d'interchangeabilité d'un premier élément à un second élément, selon le préambule de la revendication 1, une application privilégiée de ce dispositif étant la fixation d'un bracelet à une boîte de montre.The present invention relates to a device for fixing and interchangeability of a first element to a second element, according to the preamble of claim 1, a preferred application of this device being the attachment of a bracelet to a watch case .

Les dispositifs du genre précité existent aujourd'hui dans une quantité d'exécutions et de variantes aussi nombreuses que diverses. Cependant, s'ils peuvent en général répondre à l'un ou l'autre des caractères tels que polyvalence d'application, rapidité de fixation ou d'attache et de libération, fiabilité de la fermeture et, enfin, simplicité de fabrication, aucun d'entre eux ne parvient a en faire la synthèse, la véritable réunion de toutes ces caractéristiques dans un même dispositif étant très délicate et tout autre qu'évidente.Devices of the aforementioned kind exist today in a quantity of executions and variants as numerous as they are diverse. However, if they can generally respond to one or other of the characteristics such as versatility of application, speed of fixing or attachment and release, reliability of the closure and, finally, simplicity of manufacture, none of them does not manage to synthesize them, the true union of all these characteristics in the same device being very delicate and quite other than obvious.

Le but de la présente invention est de proposer un disposif réalisant cette alliance. Ce but est atteint grâce aux moyens définis dans la revendication indépendante 1, les revendications dépendantes définissant des moyens particuliers et préférentiels de construction du dispositif.The purpose of the present invention is to provide a device achieving this alliance. This object is achieved thanks to the means defined in independent claim 1, the dependent claims defining particular and preferential means of construction of the device.

A titre d'exemple, on va décrire ci-après un exemple d'exécution du dispositif selon l'invention ainsi qu'une variante de celui-ci, à l'appui du dessin annexe sur lequel:

  • les Figures 1A et 1B sont des vues en perspective respectivement d'une boîte de montre et d'un bracelet, plus précisément de l'extrémité de ce bracelet, ces deux éléments étant séparés et présentant chacun une partie du dispositif de fixation,
  • la Figure 1C est une coupe de la boîte de montre selon le plan I C,
  • la figure 1D montre, en perspective, l'extrémité d'un bracelet comportant une variante d'un élément de fixation du dispositif,
  • La figure 1E est une coupe identique à celle de la figure 1C, montrant en outre une vue de bout (selon la flèche F) de la partie du bracelet destinée à être fixée à la boîte de montre, partie placée en regard d'un logement pratiqué dans ladite boîte,
  • les figures 1F, 1G et 1H représentant une autre forme d'exécution du dispositif de fixation/libération de la montre et du bracelet,
  • la Figure 2 montre, en perspective, le mode de fixation du bracelet à la montre et la position initiale de ce dernier lors de cette fixation,
  • la Figure 3 représente ces deux éléments, boîte de montre et bracelet, fixés l'un à l'autre, dans leur position d'utilisation,
  • les Figures 4A, 4B, 5 et 6 sont des vues en perspective représentant une variante d'exécution du dispositif de fixation et sont en tout point analogues aux figures 1A, 1B, 2 et 3.
By way of example, an embodiment of the device according to the invention will be described below, as well as a variant of it, based on the attached drawing in which:
  • FIGS. 1A and 1B are perspective views respectively of a watch case and a bracelet, more precisely of the end of this bracelet, these two elements being separated and each having a part of the fixing device,
  • FIG. 1C is a section of the watch case according to the plan IC,
  • FIG. 1D shows, in perspective, the end of a bracelet comprising a variant of a fastening element of the device,
  • Figure 1E is a section identical to that of Figure 1C, further showing an end view (according to arrow F) of the part of the strap intended to be fixed to the watch case, part placed opposite a housing practiced in said box,
  • FIGS. 1F, 1G and 1H showing another embodiment of the device for fixing / releasing the watch and the bracelet,
  • FIG. 2 shows, in perspective, the method of fixing the bracelet to the watch and the initial position of the latter during this fixing,
  • FIG. 3 represents these two elements, watch case and bracelet, fixed to each other, in their position of use,
  • FIGS. 4A, 4B, 5 and 6 are perspective views showing an alternative embodiment of the fixing device and are completely similar to FIGS. 1A, 1B, 2 and 3.

Sur la figure 1B, on aperçoit un premier élément, savoir, soit l'extrémité d'un bracelet 20, soit le maillon extrême d'un bracelet 20, pourvu d'une protubérance 21. Cette dernière comporte, de part et d'autre, deux chevilles 22,23, formées, par exemple, par les parties apparentes d'un axe 27 monté serré dans un alésage pratiqué dans ladite protubérance (l'alésage lui-même n'étant pas référencé). Afin d'obtenir une fixation plus sûre, cet axe peut être avantageusement une barette 27', connue en tant que telle de l'homme du métier (voir figures 1D et 1E), les extrémités visibles 28,29 de la barrette 27' laissant apparaître des poussoirs ou pivots 22' ,23' sur ressorts (logés dans dans l'axe 27'). Enfin, la face inférieure (non référencée) de la protubérance présente une rainure ou saignée de maintien 24.In FIG. 1B, a first element can be seen, namely, either the end of a bracelet 20, or the end link of a bracelet 20, provided with a protuberance 21. The latter comprises, on either side , two pins 22,23, formed, for example, by the visible parts of a pin 27 mounted tight in a bore formed in said protuberance (the bore itself not being referenced). In order to obtain a more secure fixing, this axis can advantageously be a bar 27 ′, known as such from those skilled in the art (see FIGS. 1D and 1E), the visible ends 28, 29 of the bar 27 'revealing pushers or pivots 22', 23 'on springs (housed in the axis 27'). Finally, the lower face (not referenced) of the protuberance has a retaining groove or groove 24.

La figure 1A montre un second élément, en l'occurrence une boîte de montre 10. En lieu et place de cornes, cette boîte présente deux logements ou évidements 11, 11A, situés en face l'un de l'autre et identiques entre eux (aussi se réfèrera-t-on uniquement, par la suite, au logement 11). Les formes générales du logement 11 de la boîte 10 et de la protubérance 21 du bracelet 20 sont complémentaires, celle-ci étant destinée à être logée dans celle-la. Selon l'exemple décrit, protubérance 21 et logement 11 montrent des parties arrondies, respectivement 25 et 15, de forme équivalente. Le logement 11 est revidé, de sorte à former, selon l'exemple, un épaulement (voir figure 1C), la face 13 de cet épaulement étant, selon une exécution, parallèle à la face 12 du logement 11. A sa partie inférieure, le logement 11 laisse subsister une lamelle de maintien 14. Bien entendu, la distance entre les extrémités des chevilles 22 et 23 est légèrement inférieure à celle séparant la face gauche et la face droite de l'épaulement 13 (figure 1C). De plus, les dimensions du logement sont définies de telle sorte que l'opération de fixation (et de l'opération inverse, c'est-à-dire de libération) telles qu'exposées ci-dessous soient possibles.FIG. 1A shows a second element, in this case a watch box 10. In place of horns, this box has two housings or recesses 11, 11A, located opposite one another and identical to each other (also we will only refer later to the housing 11). The general forms of the housing 11 of the box 10 and of the protrusion 21 of the bracelet 20 are complementary, the latter being intended to be housed therein. According to the example described, protuberance 21 and housing 11 show rounded parts, respectively 25 and 15, of equivalent shape. The housing 11 is rewound, so as to form, according to the example, a shoulder (see FIG. 1C), the face 13 of this shoulder being, in one embodiment, parallel to the face 12 of the housing 11. At its lower part, the housing 11 leaves a retaining strip 14. Of course, the distance between the ends of the pins 22 and 23 is slightly less than that separating the left face and the right face of the shoulder 13 (FIG. 1C). In addition, the dimensions of the housing are defined so that the fixing operation (and the reverse operation, that is to say of release) as set out below are possible.

La figure 2 montre les deux éléments 10 et 20 en phase de fixation l'un à l'autre, les opérations de cette phase étant symbolisées par les flèches 30 et 31. Lorsque les opérations de cette phase sont achevées, ces deux éléments se présentant tels que représentés à la figure 3.FIG. 2 shows the two elements 10 and 20 in the phase of attachment to each other, the operations of this phase being symbolized by the arrows 30 and 31. When the operations of this phase are completed, these two elements appearing as shown in Figure 3.

A la seule lecture des figures 2 et 3, on comprend aisément le mode de fixation. Dans un premier temps, la protubérance 21 du bracelet 20 est introduite dans le logement 11, dans la position montrée à la figure 2, quasi perpendiculairement à la boîte 10, selon la flèche 30 (le plan (non référence) de la partie extrême du bracelet pourvu de la protubérance se confondant très approximativement avec le plan de symétrie de la boîte de montre, c'est-à-dire du logement 11), la cheville 22 (ou partie 28 et poussoir 22' selon la forme d'exécution de la figure 1D) venant se placer dans l'épaulement 13, de sorte que l'autre cheville 23 (ou partie 29 et poussoir 23'), tout en imprimant, dans un deuxième temps, un mouvement de rotation au bracelet (flèche 31), puisse également prendre place dans l'épaulement 13. Dans un troisième temps, une fois que les chevilles 22,23 (ou parties 28,29, poussoirs 22',23') se trouvent dans l'épaulement 13 et que le pivotement est terminé, les plans médians ou de symétrie (non référencés) de la potubérance 21 et du logement 11 se confondant à nouveau progressivement, le bracelet est rabattu, selon la flèche 32 (figure 3). Lors de la phase terminale de cette opération de rabattement, la rainure 24 se positionne sur la lamelle 14, et les faces 16 et 26, respectivement de la boîte 10 et du bracelet 20, se trouvent en regard l'une de l'autre. Les deux éléments, bracelet 20 et boîte de montre 10 selon l'exemple, sont ainsi rendus solidaires l'un de l'autre grâce à ce dispositif dont les moyens permettent, comme on l'aura remarqué, un type d'emboîtement à baïonnette. La désolidarisation des deux éléments est obtenue très rapidement, en effectuant les mouvements inverses de ceux décrits plus haut, ce qui facilite sensiblement l'interchangeabilité des bracelets, tout comme celle des boîtes de montre.By simply reading Figures 2 and 3, one can easily understand the method of attachment. Firstly, the protuberance 21 of the bracelet 20 is introduced into the housing 11, in the position shown in FIG. 2, almost perpendicular to the case 10, along the arrow 30 (the plane (not reference) of the extreme part of the bracelet provided with the protrusion merging very roughly with the plane of symmetry of the watch case, that is to say of the housing 11), the ankle 22 (or part 28 and pusher 22 'according to the embodiment of Figure 1D) coming to be placed in the shoulder 13, so that the other pin 23 (or part 29 and pusher 23 '), while printing, in a second step, a rotational movement of the bracelet (arrow 31) , can also take place in the shoulder 13. Thirdly, once the pins 22,23 (or parts 28,29, pushers 22 ′, 23 ′) are in the shoulder 13 and that the pivoting is finished, the median or symmetry planes (not referenced) of potuberation 21 and of housing 11 gradually merging again, the bracelet is folded down, according to arrow 32 (Figure 3). During the terminal phase of this folding operation, the groove 24 is positioned on the strip 14, and the faces 16 and 26, respectively of the case 10 and the bracelet 20, are located opposite one another. The two elements, bracelet 20 and watch case 10 according to the example, are thus made integral with one another thanks to this device whose means allow, as will have been noticed, a type of bayonet fitting . The separation of the two elements is obtained very quickly, by performing the reverse movements of those described above, which appreciably facilitates the interchangeability of the straps, just like that of watch cases.

On a vu que l'opération de fixation est bien sûr analogue à celle venant d'être décrite, lorsque la protubérance 21 est pourvue de la barette 27'. A titre de précision, on a représenté à la figure 1E (coupe pratiquée à l'emplacement du logement 11 de la boîte de montre, identique à celle montrée à la figure 1C), en regard dudit logement, la protubérance 21 vue selon la flèche F (figure 1D), de sorte à mettre en apparence le positionnement approximatif (lignes pointillées) des parties 28,29 de la barette ainsi que des poussoirs 22',23', par rapport aux faces 12,13 du logement 11. Lorsque la protubérance est engagée dans le logement 11 pour y être fixée, chacun des poussoirs 22',23' prend appui sur l'épaulement 13 contre l'action de la force du ressort respectif, ce qui confère au dispositif une meilleure sécurité de fixation.We have seen that the fixing operation is of course similar to that just described, when the protrusion 21 is provided with the bar 27 '. For clarification, there is shown in FIG. 1E (section made at the location of the housing 11 of the watch case, identical to that shown in FIG. 1C), opposite said housing, the protuberance 21 seen according to arrow F (FIG. 1D), so to put in appearance the approximate positioning (dotted lines) of the parts 28, 29 of the bar as well as of the pushers 22 ', 23', with respect to the faces 12, 13 of the housing 11. When the protuberance is engaged in the housing 11 for be attached thereto, each of the pushers 22 ′, 23 ′ bears on the shoulder 13 against the action of the force of the respective spring, which gives the device better fixing security.

Les figures 4A, 4B, 5 et 6 représentent une variante de l'exemple d'exécution venant d'être décrit. Selon cette variante, les moyens du dispositif permettant l'emboîtement à baïonnette sont ici inversés: la boîte de montre 30 présente, en lieu et place des cornes, deux protubérances 31 et 31A, chacune comportant un axe 37 et des chevilles 32,33 (éléments analogues aux éléments 27,22,23) et une rainure ou saignée 34, tandis que l'extrémité du bracelet 40 présente un évidement ou logement 41 de forme complémentaire à la protubérance 31 et relié, à sa partie inférieure, par une lamelle 44. A l'instar du logement 11, des figures 1A, 1C, le logement 41 présente un épaulement 43. La fixation s'obtient en appliquant le même processus que celui décrit plus haut et illustré, sur les figures 5 et 6, par les flèches 50 (introduction de la protubérance 31 dans le logement 41, c'est-à-dire des chevilles dans la partie revidée 43 de l'encoche 41, les deux éléments étant placés quasi perpendiculairement l'un par rapport à l'autre et l'orientation de leurs plans étant, comme représenté à la figure 5, quasi orthogonale), puis 51 (pivotement) et enfin 52 (rabattement). Le processus inverse conduit, là aussi, à la libéralisation des deux éléments, lorsque l'on souhaite, par exemple, changer de bracelet ou de boîte de montre.FIGS. 4A, 4B, 5 and 6 show a variant of the embodiment which has just been described. According to this variant, the means of the device allowing the bayonet fitting are here reversed: the watch case 30 has, in place of the horns, two protuberances 31 and 31A, each comprising an axis 37 and pins 32.33 ( elements similar to elements 27, 22, 23) and a groove or groove 34, while the end of the bracelet 40 has a recess or housing 41 of shape complementary to the protuberance 31 and connected, at its lower part, by a strip 44 Like the housing 11, in FIGS. 1A, 1C, the housing 41 has a shoulder 43. The fixing is obtained by applying the same process as that described above and illustrated, in FIGS. 5 and 6, by the arrows 50 (introduction of the protuberance 31 into the housing 41, that is to say pegs in the recessed part 43 of the notch 41, the two elements being placed almost perpendicularly to each other and the orientation of their plans As, as shown in Figure 5, almost orthogonal) and 51 (pivot) and finally 52 (drawdown). Here too, the opposite process leads to the liberalization of the two elements, when one wishes, for example, to change the strap or watch case.

A l'instar de la variante décrite à l'appui de la figure 1D (barette 27' munie de poussoirs 22',23'), il va de soi que l'on peut avantageusement prévoir, en lieu et place de l'axe 37, une barette 37' (figure 4A), comportant des poussoirs 32',33').Like the variant described in support of Figure 1D (bar 27 'provided with pushers 22', 23 '), it goes without saying that one can advantageously provide, instead of the axis 37, a bar 37 '(Figure 4A), comprising pushers 32', 33 ').

La sécurité de fixation peut encore être sensiblement améliorée, grâce à une conformation particulièrement intéressante du logement 11 des figures 1A, 1B, 1C ou du logement 41 des figures 4A, 4B, selon la variante choisie.The fixing security can be further improved significantly, thanks to a particularly advantageous conformation of the housing 11 of FIGS. 1A, 1B, 1C or of the housing 41 of FIGS. 4A, 4B, depending on the variant chosen.

On se référera, pour la description de cette particularité aux figures 1F, 1G et 1H. Dans ces figures, les références 10, 11, 12 et 13 ont été maintenues, en dépit des modifications de forme. La figure 1G est une coupe de la montre 10 selon la ligne 6⁰⁰-12⁰⁰, la figure 1F est une coupe analogue à celle représentée à la figure 1C, et la figure 1H est une vue en perspective par le dessous de la montre 10.For the description of this feature, reference is made to FIGS. 1F, 1G and 1H. In these figures, the references 10, 11, 12 and 13 have been retained, despite the changes in form. FIG. 1G is a section of watch 10 along the line 6⁰⁰-12⁰⁰, FIG. 1F is a section similar to that shown in FIG. 1C, and FIG. 1H is a perspective view from below of watch 10.

On aperçoit que l'épaulement 13 est circulaire -ce qui peut d'ailleurs être également le cas pour l'épaulement 13 des figures 1A, 1C-. Mais la particularité essentielle consiste ici en un revidage supplémentaire 13A, dans lequel prend place un organe élastique 13B, lequel organe peut être soit en métal, soit en matière synthétique. A titre d'exemple, l'élément élastique, remplissant une fonction de ressort, est une bague d'acier non fermée et ondulée telle qu'on peut l'apercevoir à la figure 1H. On comprend que la liaison et la séparation des éléments 20, 10 entre eux (cf. aussi figures 1A et 1B) ou des éléments 40, 30 entre eux (cf. aussi figures 4A et 4B) se pratiquent de la même manière que celle décrite plus haut (procédé baïonette). L'organe-ressort 13B assurant une excellente sûreté de liaison grâce à l'action qu'il exerce sur les chenilles 22, 23; 32, 33, les poussoirs 22', 23' (figures 1D, 1E) s'avèrent ici inutiles.We see that the shoulder 13 is circular - which can also be the case for the shoulder 13 of Figures 1A, 1C-. But the essential feature here consists of an additional rewinding 13A, in which takes place an elastic member 13B, which member can be either of metal or of synthetic material. By way of example, the elastic element, fulfilling a spring function, is an unclosed and corrugated steel ring as can be seen in FIG. 1H.
