Clasp for a metal bracelet (3) consisting of members pivoted together, said clasp comprising a first part (1) which is pivoted to one end of the bracelet (3) and on which is pivoted an intermediate member (4) having an end bent into the shape of a hook (20) and intended to engage behind a bar (13) of a second part (2) pivoted to the other end of the bracelet and to be folded back over the first part by pulling the second part of the clasp towards the first part and bringing a portion of said second part of the clasp into engagement with a profile of the first part of the clasp, characterized by the fact that the clasp is entirely composed of segments of sectional bars, said first and second parts each being composed of two sectional bar segments (5, 6 and 11, 12 respectively) connected to the members of the bracelet (3) by pins (9, 14), the two segments (5, 6) of the first part being in addition connected by an intermediate bar (8) and an end bar (7), and the two segments (11, 12) of the second part of the clasp being connected by an end bar (13), by the fact that the intermediate member (4) is composed of a segment of a tubular section of the flat type having on the one hand a part (21 ; 23 ; 24, 25) by which it is pivoted on the end bar (7) of the first part of the clasp at a point situated at a certain distance from one end (22) of the flat profile, and on the other hand a slot (19) whose width is at least equal to the diameter of the end bar (13) of the second part of the clasp and which is situated at a certain distance from the other end of the interior of the flat tubular profile, in such a manner as to form a hook (20), said slot being intended for the engagement of said bar (13) in the profile (18), and by the fact that the facing ends of the two parts of the clasp have paired profiles (16, 17) in such a manner that said ends interengage through their paired profiles when they are superimposed on the folding back of the intermediate member (4) over the first part of the clasp.

Description

La présente invention a pour objet un fermoir pour bracelet métallique constitué d'éléments articulés entre eux, notamment un bracelet de montre, ce fermoir comprenant une première partie articulée à l'une des extrémités du bracelet sur laquelle est articulé un élément intermédiaire présentant une extrémité coudée en forme de crochet et destiné à s'engager derrière une barrette d'une deuxième partie articulée à l'autre extrémité du bracelet pour être rabattue en arrière sur la première partie en tirant la deuxième partie du fermoir vers la première partie et en amenant une partie de cette deuxième partie du fermoir en prise avec un profil de la première partie du fermoir.The subject of the present invention is a clasp for a metallic bracelet made up of elements articulated together, in particular a watch strap, this clasp comprising a first part articulated at one of the ends of the bracelet on which is articulated an intermediate element having one end. angled in the shape of a hook and intended to engage behind a bar of a second part hinged at the other end of the bracelet to be folded back on the first part by pulling the second part of the clasp towards the first part and bringing part of this second part of the clasp engaged with a profile of the first part of the clasp.

On connaît un fermoir de ce type (LONGINES) dont les différentes parties sont constituées par des pièces découpées et fraisées de manière à permettre leur articulation entre-elles et aux extrémités du bracelet. La barrette de la deuxième partie du fermoir vient s'engager dans une rainure fraisée dans la première partie lorsque l'élément intermédiaire est rabattu sur la première partie. Cet élément intermédiaire venant se fixer à cran sur le bord transversal de la première partie du fermoir, sa partie coudée ne forme qu'un léger crochet qui ne retient que d'une manière peu sûre la deuxième partie du fermoir lors d'une ouverture accidentelle du fermoir. Ce fermoir exige un usinage coûteux et il ne peut être utilisé que pour une seule largeur de bracelet.A clasp of this type is known (LONGINES), the different parts of which consist of pieces cut and milled so as to allow them to be articulated with one another and at the ends of the bracelet. The bar of the second part of the clasp engages in a countersunk groove in the first part when the intermediate element is folded over the first part. This intermediate element coming attach to the notch on the transverse edge of the first part of the clasp, its bent part forms only a slight hook which only retains the second part of the clasp in an insecure manner during an accidental opening of the clasp. This clasp requires expensive machining and can only be used for one width of bracelet.

La présente invention a pour but de réaliser un fermoir sans fraisage, au moyen d'éléments susceptibles d'être obtenus par tronçonnage d'un profilé et permettant dès lors une adaptation à toute largeur de bracelet, respectivement toute largeur d'élément articulé d'un bracelet. Le fermoir doit en outre offrir une meilleure sécurité d'une part contre une ouverture accidentelle et d'autre part en cas d'ouverture accidentelle. Ces but sont atteints par les caractéristiques définies à la revendication 1.The object of the present invention is to produce a clasp without milling, by means of elements capable of being obtained by cutting off a profile and therefore allowing adaptation to any width of bracelet, respectively any width of articulated element of a bracelet. The clasp must also offer better security on the one hand against accidental opening and on the other hand in case of accidental opening. These objects are achieved by the characteristics defined in claim 1.

Les deux parties du fermoir et l'élément intermédiaire peuvent être obtenus, à la largeur désirée, par tronçonnage d'une barre, respectivement d'un tube profilé. Les deux éléments formant respectivement la première et la deuxième parties sont assemblées au bracelet comme les éléments articulés formant le bracelet.The two parts of the clasp and the intermediate element can be obtained, at the desired width, by cutting a bar, respectively a profiled tube. The two elements respectively forming the first and the second parts are assembled to the bracelet like the articulated elements forming the bracelet.

L'articulation de l'élément intermédiaire étant situé à une certaine distance de l'extrémité, la pression du poignet sur cette extrémité excentrée s'oppose à la rotation de l'élément intermédiaire et par conséquent à une ouverture accidentelle du fermoir.The articulation of the intermediate element being located at a certain distance from the end, the pressure of the wrist on this eccentric end opposes the rotation of the intermediate element and consequently an accidental opening of the clasp.

L'autre extrémité de l'élément intermédiaire présente un crochet qui peut être relativement profond et dans lequel la barrette de la deuxième partie du fermoir est retenue de façon sûre en cas d'ouverture accidentelle du fermoir.The other end of the intermediate element has a hook which can be relatively deep and in which the bar of the second part of the clasp is securely retained in the event of accidental opening of the clasp.

Le fermoir est constitué de deux parties 1 et 2 (6) reliables respectivement aux deux extrémités d'un bracelet 3 (figure 7) constitué de trois rangées d'éléments métalliques articulés entre eux au moyen de goupilles ou d'axes de manière connue, et d'un élément intermédiaire 4. La partie 1 est constituée de deux segments 5 et 6 profilés identiques, espacé l'un de l'autre et relié entre-eux par trois goupilles ou axes 7, 8, 9 (figure 1). Sur l'axe 9 est articulé un élément 10 qui relie le fermoir au bracelet 3 et qui peut être considéré soit comme un élément du fermoir soit comme un élément du bracelet. Sur la goupille 7 est articulé l'élément intermédiaire 4 représenté en position ouverte du fermoir à la figure 6. La partie 2 du fermoir est constitué de deux éléments profilés 11 et 12 espacés l'un de l'autre et reliés entre-eux par deux goupilles 13 et 14, la goupille 13 formant une barrette. Sur la goupille 14 est articulé un élément 15 identique à l'élément 10 et servant également à la liaison de la partie 2 du fermoir au bracelet. Le fermoir en position fermée est intégré au bracelet et représenté à la figure 7.The clasp consists of two parts 1 and 2 (6) respectively connectable to the two ends of a bracelet 3 (FIG. 7) consisting of three rows of metal elements hinged together by means of pins or pins in a known manner, and of an intermediate element 4. Part 1 consists of two segments 5 and 6 identical sections, spaced from one another and connected together by three pins or pins 7, 8, 9 (FIG. 1). On the axis 9 is articulated an element 10 which connects the clasp to the bracelet 3 and which can be considered either as an element of the clasp or as an element of the bracelet. On the pin 7 is articulated the intermediate element 4 shown in the open position of the clasp in Figure 6. The part 2 of the clasp consists of two profiled elements 11 and 12 spaced from one another and connected together by two pins 13 and 14, the pin 13 forming a bar. On the pin 14 is articulated an element 15 identical to the element 10 and also serving for the connection of the part 2 of the clasp to the bracelet. The clasp in the closed position is integrated into the bracelet and shown in Figure 7.

La forme des profilés des éléments 5 et 6, respec­tivement 11 et 12 est visibles aux figures 1 à 3. Les éléments 5 et 6 de la partie 1 présentent, entre les goupilles 7 et 8, une gorge arrondie 16 ouverte vers le haut, tandis que les éléments 11 et 12 présentent une gorge analogue 17 mais ouverte vers le bas. Ces gorges 16 et 17 définissent avec les extrémités des éléments en regard des profils conjugés tels que lorsque les extrémités des parties 1 et 2 sont superposées (figure 3), ces profils conjugés s'interpénètrent et s'épousent parfaitement de telle manière que l'assemblage obtenu a la même épaisseur que chacune des parties 1 et 2.The shape of the sections of elements 5 and 6, respectively 11 and 12 is visible in Figures 1 to 3. The elements 5 and 6 of part 1 have, between the pins 7 and 8, a rounded groove 16 open upwards, while that the elements 11 and 12 have a similar groove 17 but open downwards. These gorges 16 and 17 define with the ends of the elements opposite conjugate profiles such that when the ends of parts 1 and 2 are superimposed (FIG. 3), these conjugate profiles interpenetrate and marry perfectly so that the assembly obtained has the same thickness as each of parts 1 and 2.

L'élément intermédiaire 4 se présente sous la forme d'un segment de profilé tubulaire plat, c'est-à-dire présentant un profil intérieur oblong 18. L'épaisseur totale de ce profilé est égale à l'épaisseur des éléments 6 et 12. La largeur du profil intérieur 18 est sensiblement égale au diamètre de la goupille 8. L'élément 4 est muni d'une fente transversale 19 dont la largeur est légèrement supérieure au diamètre de la barrette 13 de manière à permettre le passage aisé de cette barrette à travers cette fente. La fente 19 située à une certaine distance de l'extrémité droite de l'élément 4, définit en outre un crochet 20. Le profilé 4 présente en outre un profilé auxiliaire en U soudé au profil 4 et formant un passage pour la goupille 7 autour de laquelle est articulé l'élément 4.The intermediate element 4 is in the form of a segment of flat tubular profile, that is to say having an oblong internal profile 18. The total thickness of this profile is equal to the thickness of the elements 6 and 12. The width of the internal profile 18 is substantially equal to the diameter of the pin 8. The element 4 is provided with a transverse slot 19 whose width is slightly greater than the diameter of the bar 13 so as to allow easy passage of this bar through this slot. The slot 19 located at a certain distance from the right end of the element 4, further defines a hook 20. The profile 4 also has an auxiliary U-shaped profile welded to the profile 4 and forming a passage for the pin 7 around from which element 4 is articulated.

La fermeture du fermoir s'opère de la manière suivante : la barrette 13 de la partie 2 est engagée dans l'élément intermédiaire 4 à travers la fente 19 et pénètre au fond du crochet 20 dans laquel il est retenu avec une sécurité relativement grande. L'élément intermédiaire 4 est ensuite soulevé par son extrémité droite (figure 2), ce qui à pour effet de faire glisser la barrette 13 dans le profil 18 en direction de la partie 1 du fermoir jusqu'à ce que l'extrémité de la partie 2 vienne buté avec l'extrémité de la partie 1. En poursuivant la rotation de l'élément 4 on fait passer l'extrémité profilée de la partie 2 au dessus de l'extrémité de profil conjugué de la partie 1 de telle sorte que ces deux parties de profils conjugués viennent s'emboîter comme représenté à la figure 3. L'extrémité du crochet 20 vient finalement buter contre la goupille 8 mais peut toutefois la dépasser en se déformant élastiquement par une légère pression sur l'élément 4. Cet élément 4 vient en outre s'appuyer par sa partie droite sur les goupilles 8 et 13 de manière à épouser finalement le profil des autres éléments du fermoir et du bracelet.The closure of the clasp operates as follows: the bar 13 of the part 2 is engaged in the intermediate element 4 through the slot 19 and enters the bottom of the hook 20 in which it is retained with relatively great security. The intermediate element 4 is then lifted by its straight end (FIG. 2), which has the effect of sliding the bar 13 in the profile 18 in the direction of part 1 of the clasp until the end of the part 2 comes to a stop with the end of part 1. By continuing the rotation of element 4 we do pass the profiled end of part 2 above the end of the conjugate profile of part 1 so that these two parts of conjugate profiles fit together as shown in FIG. 3. The end of the hook 20 comes finally abut against the pin 8 but can however exceed it by deforming elastically by a slight pressure on the element 4. This element 4 also comes to rest by its right part on the pins 8 and 13 so as to finally marry the profile of the other elements of the clasp and bracelet.

Comme on peut le constater à la figure 7, le fermoir fermé est parfaitement intégré au bracelet et il peut être réalisé de telle sorte qu'il est difficile de distinguer ces éléments des éléments constituant le bracelet.As can be seen in FIG. 7, the closed clasp is perfectly integrated into the bracelet and it can be produced in such a way that it is difficult to distinguish these elements from the elements constituting the bracelet.

Il ressort clairement de la figure 3 que les parties 1 et 2 du fermoir sont directement accrochées l'une à l'autre. L'élément intermédiaire 4 ne supporte pas d'effort de traction mais empêche simplement les parties de profil conjuguées de se séparer l'une de l'autre transversalement.It is clear from Figure 3 that parts 1 and 2 of the clasp are directly attached to each other. The intermediate element 4 does not support any tensile force but simply prevents the parts of the conjugate profile from separating from each other transversely.

Ce fermoir présente en outre une grande sécurité contre une ouverture accidentelle. En effet, l'extrémité 22 de l'élément intermédiaire 4 est située à un certaine distance de l'axe de pivotement de cet élément 4. En cas de décrochement accidentel du crochet 20 de la barrette 8 et de soulèvement de l'élément 4, son extrémité 22 vient en effet buter contre le poignet du porteur et il faut un effort particulier pour vaincre cette résistance. Si malgré tout l'élément 4 parvient à basculer de plus de 90° pour retomber dans la position représentée à la figure 1, la barrette 13 est encore bien retenue au fond du crochet 20. Malgré sa simplicité ce fermoir est donc d'une grande sécurité.This clasp also has great security against accidental opening. Indeed, the end 22 of the intermediate element 4 is located at a certain distance from the pivot axis of this element 4. In the event of accidental detachment of the hook 20 from the bar 8 and lifting of the element 4 , its end 22 indeed abuts against the wrist of the wearer and a special effort is required to overcome this resistance. If despite everything element 4 succeeds in tilt more than 90 ° to fall back into the position shown in Figure 1, the bar 13 is still well retained at the bottom of the hook 20. Despite its simplicity this clasp is therefore very secure.

La figure 4 représente une variante d'exécution du profilé constituant l'élément intermédiaire 4. Dans cette variante 4' le passage pour la goupille d'articulation 7 est formée par une partie repliée 23 du bord de la fente 19.FIG. 4 represents an alternative embodiment of the profile constituting the intermediate element 4. In this alternative 4 'the passage for the hinge pin 7 is formed by a folded part 23 from the edge of the slot 19.

Une troisième forme d'exécution de l'élément intermé­diaire est représentée à la figure 5. Cet élément 4" est constitué ici d'un segment de profilé plus massif que dans les exécutions précédentes. Le passage pour la goupille 7 est formé ici par deux gorges en arc de cercle 24 et 25 formant un cercle partiel. La gorge 19 présente en outre des faces inclinées facilitant l'introduction de la barrette 13 tout en ayant une ouverture de fente aussi faible que possible, ce qui augmente encore la sécurité. L'extrémité du fermoir proche de la fente présente en outre une rainure 26 facilitant la préhension de l'élément 4" par le bout du doigt ou par l'ongle.A third embodiment of the intermediate element is shown in FIG. 5. This element 4 "here consists of a more solid section segment than in the previous embodiments. The passage for the pin 7 is formed here by two grooves in an arc 24 and 25 forming a partial circle The groove 19 also has inclined faces facilitating the introduction of the bar 13 while having a slot opening as small as possible, which further increases safety. the end of the clasp close to the slot also has a groove 26 facilitating the gripping of the element 4 "by the tip of the finger or by the nail.

Les éléments du fermoir étant constitués d'éléments profilés sans fraisage, ils peuvent être obtenus simplement par tronçonnage d'une barre profilée. Il est donc possible d'obtenir facilement des éléments de largeur quelconque, ce qui permet de satisfaire n'importe qu'elle demande. La figure 8 illustre un autre exemple de bracelet métallique constitué d'éléments centraux 26 relativement très larges et d'éléments latéraux 27 et 28 relativement très étroits.The elements of the clasp being made up of profiled elements without milling, they can be obtained simply by cutting off a profiled bar. It is therefore possible to easily obtain elements of any width, which makes it possible to satisfy any demand. FIG. 8 illustrates another example of a metallic bracelet made up of relatively very wide central elements 26 and relatively very narrow lateral elements 27 and 28.

Le fermoir correspondant est constitué d'un élément intermédiaire 4 de même largeur que les éléments 26, tandis que les éléments 5, 6, 11 et 12 du fermoir sont constitués d'éléments de même largeur que les éléments 27 et 28.The corresponding clasp consists of an intermediate element 4 of the same width as the elements 26, while the elements 5, 6, 11 and 12 of the clasp consist of elements of the same width as the elements 27 and 28.
