INTERCHANGEABLEINTERCHANGEABLE
La présente invention se situe dans le domaine des montres à bracelet. Elle concerne un dispositif destiné à permettre de changer rapidement et facilement un bracelet sur un boitier de montre à porter au poignet. Pour diverses raisons liées majoritairement à des considérations esthétiques, la personne portant une montre-bracelet souhaite pouvoir interchanger le bracelet.The present invention is in the field of wrist watches. It relates to a device intended to allow a bracelet to be changed quickly and easily on a watch case to be worn on the wrist. For various reasons mainly related to aesthetic considerations, the person wearing a wristwatch wishes to be able to interchange the bracelet.
C'est le cas pour une recherche d'harmonie avec les vêtements d'une soirée, mais aussi pour une recherche de confort. Cette amélioration de confort est bien réelle dans la mesure où un autre bracelet, de par le changement de matière et de type de fermoir, permet de procurer une sensation plus agréable au port de la montre-bracelet .This is the case for a search for harmony with evening wear, but also for a search for comfort. This improvement in comfort is very real insofar as another bracelet, by the change of material and type of clasp, makes it possible to provide a more pleasant feeling when wearing the wristwatch.
La présente invention a pour but de satisfaire ces deux exigences simultanément.The object of the present invention is to satisfy these two requirements simultaneously.
A cet effet, elle se rapporte à un dispositif de maintien de 1 ' extrémité d ' un bracelet pour boîtier de montre à extrémités du type en sandwich dans lesquelles 1 ' extrémité de chaque branche du bracelet est prise entre deux plaques et immobilisée entre celles-ci par des éléments de fixation traversants pour la plaque arrière et le bracelet. Le dispositif de maintien libérable selon l'invention se caractérise par un bloc pivotant pourvu d'une rangée de tétons ou de picots venant se loger dans des perforations prévues dans 1 ' épaisseur de l'extrémité du bracelet, le pivotement du bloc provoquant le maintien de 1 ' extrémité du bracelet lorsque ce bloc pivotant arrive dans sa position finale rabattue de fin de course. Les avantages procurés par ce dispositif sont ceux de la rapidité et de 1 ' aisance de la manoeuvre de substitution, de la solidité technique de la fixation du bracelet au boîtier et de la simplicité de fabrication et de montage du dispositif.To this end, it relates to a device for holding the end of a strap for a watch case with ends of the sandwich type in which the end of each branch of the strap is taken between two plates and immobilized between them. ci by through fixing elements for the back plate and the bracelet. The releasable holding device according to the invention is characterized by a pivoting block provided with a row of pins or pins coming to be housed in perforations provided in the thickness of the end of the bracelet, the pivoting of the block causing the holding of the end of the bracelet when this pivoting block arrives in its final folded end position. The advantages provided by this device are those of the speed and ease of the substitution maneuver, the technical solidity of the fixing of the bracelet to the case and the simplicity of manufacture and assembly of the device.
Il faut mentionner également comme avantage important, le caractère d'auto-maintien de la liaison au boîtier lorsque le bracelet est en place.An important advantage should also be mentioned, the self-maintaining nature of the connection to the case when the bracelet is in place.
D ' autres caractéristiques et avantages de l'invention apparaîtront dans la description qui suit, donnée à titre d'exemple non limitatif en référence au dessin dans lequel :Other characteristics and advantages of the invention will appear in the following description, given by way of nonlimiting example with reference to the drawing in which:
. la figure 1 est une vue générale en perspective d'une montre vue de dessous comportant le dispositif de maintien du bracelet selon l'invention ;. Figure 1 is a general perspective view of a watch seen from below comprising the strap holding device according to the invention;
. la figure 2 est une vue en perspective de 1 ' extrémité du boîtier et du dispositif selon l'invention montrant à l'état dissocié l'ensemble des pièces y compris le bracelet ; . la figure 3 est une vue en perspective du bloc pivotant seul vu de 3/4 arrière ; . les figures 4 et 5 sont des coupes transversales d'une extrémité du boîtier dans les deux positions extrêmes du bloc pivotant de maintien respectivement de maintien et de libération.. Figure 2 is a perspective view of one end of the case and of the device according to the invention showing in the dissociated state all the parts including the bracelet; . Figure 3 is a perspective view of the only pivoting block seen from 3/4 rear; . Figures 4 and 5 are cross sections of one end of the housing in the two extreme positions of the pivoting holding block respectively holding and release.
Le dispositif selon l'invention est plus particulièrement, mais non exclusivement prévu pour un boîtier 1 de montre du type formé par deux plaques 1 ' une inférieure 2 et 1 ' autre supérieure 3 séparées par une âme-cadran 4. On vise également et surtout un boîtier monobloc 1 identique ou équivalent pour lequel les formes sont obtenues par usinage dans une seule pièce. Les plaques 2 et 3, ou leurs équivalents en formes techniques dans le cas de la réalisation monobloc, se terminent par deux parois d'extrémités inférieure 5 et supérieure 6 superposées et séparées par l'extrémité 7 en retrait de l'âme-cadran 4, ou du coeur de la pièce monobloc, pour délimiter entre elles un espace récepteur 8 d ' extrémité. Dans cet espace récepteur 8 vient s ' insérer une extrémité 9 d' une branche 10 d'un bracelet 11 qui se trouve ainsi prise en sandwich entre les deux parois d ' extrémité 5 et 6.The device according to the invention is more particularly, but not exclusively intended for a watch case 1 of the type formed by two plates 1 ', a lower 2 and 1' the other upper 3 separated by a core-dial 4. The aim is also and above all an identical or equivalent one-piece housing 1 for which the shapes are obtained by machining in one piece. The plates 2 and 3, or their equivalent in technical forms in the case of the monobloc embodiment, end in two walls of lower ends 5 and upper 6 superimposed and separated by the end 7 set back from the core-dial 4 , or core of the one-piece part, to delimit between them a receptor space 8 at the end. In this receiving space 8 is inserted an end 9 of a branch 10 of a bracelet 11 which is thus sandwiched between the two end walls 5 and 6.
L ' invention est indépendante des caractéristiques générales telles que celles de la matière, la flexibilité, l'état de surface et autres particularités du bracelet. Le mécanisme du dispositif de maintien amovible selon 1 ' invention se compose essentiellement d'un bloc 12 transversal de maintien monté pivotant sur 1 ' extrémité de la paroi inférieure d ' extrémité 5 et plus précisément entre les deux extrémités en regard 13 et 14 de cette paroi inférieure préalablement sectionnée afin de ménager un emplacement transversal libre occupé par le bloc transversal pivotant 12 de maintien.The invention is independent of general characteristics such as those of the material, the flexibility, the surface condition and other peculiarities of the bracelet. The mechanism of the removable holding device according to the invention essentially consists of a transverse holding block 12 pivotally mounted on the end of the lower end wall 5 and more precisely between the two opposite ends 13 and 14 of this lower wall previously sectioned in order to provide a free transverse location occupied by the pivoting transverse holding block 12.
Ce bloc 12 est monté pivotant par exemple par 1 ' intermédiaire de deux bouts d ' axe perpendiculaires à ses chants transversaux ou d'un axe traversant 15. Le bloc pivotant 12 présente un chant longitudinal avant arrondi 16 et un chant longitudinal arrière 17 marqué par un évidement en forme d'encoche curviligne 18 permettant sa manoeuvre par l'extrémité d'un ongle.This block 12 is pivotally mounted for example by the intermediary of two ends of the axis perpendicular to its transverse edges or of a through axis 15. The pivoting block 12 has a rounded front longitudinal edge 16 and a rear longitudinal edge 17 marked by a recess in the form of a curvilinear notch 18 allowing it to be maneuvered by the end of a nail.
Ce bloc pivotant 12 comporte sur sa face supérieure 19 une pluralité d'éléments de retenue disposés selon une rangée transversale au boîtier sous la forme de tétons ou de picots 20 perpendiculaires à son plan. Ces picots 20 assurent le maintien de 1 ' extrémité 9 de la branche du bracelet par pénétration dans des perforations 21 correspondantes traversantes ou non pratiquées dans la matière du bracelet ou dans le cas de picots pointus par une auto-pénétrâtion. L'espace récepteur 8 d'extrémité est conformé en une cavité en fente 22 réceptrice de l'extrémité 9 de la branche du bracelet. Cette extrémité 9 est plaquée contre la face supérieure 19 du bloc pivotant 12 en la plaçant correctement sur les picots 20.This pivoting block 12 has on its upper face 19 a plurality of retaining elements arranged in a row transverse to the housing in the form of pins or pins 20 perpendicular to its plane. These pins 20 maintain the end 9 of the branch of the bracelet by penetration into corresponding perforations 21 through or not made in the material of the bracelet or in the case of sharp pins by self-penetration. The receiving space 8 at the end is shaped into a slot cavity 22 receiving the end 9 of the branch of the bracelet. This end 9 is pressed against the upper face 19 of the pivoting block 12 by placing it correctly on the pins 20.
Lors de la phase finale du montage, elle se trouve entraînée par le mouvement de pivotement du bloc 12 au besoin assisté par une poussée pratiquée sur le bracelet vers le boîtier pour 1 ' amener au fond de la cavité réceptrice 22.During the final phase of assembly, it is driven by the pivoting movement of the block 12 if necessary, assisted by a push made on the bracelet towards the case to bring it to the bottom of the receiving cavity 22.
L'extrémité 9 du bracelet prise en sandwich entre les extrémités des parois 5 et 6 est maintenue dans la cavité réceptrice 22 en fente dans un état de logement étroit et ancrage par les picots 20.The end 9 of the bracelet sandwiched between the ends of the walls 5 and 6 is held in the receiving cavity 22 in a slot in a narrow housing state and anchored by the pins 20.
Une poussée sur le bracelet vers le boîtier fait buter son extrémité contre le fond de la cavité réceptrice 22 de 1 ' espace récepteur 8. Une traction sur la branche du bracelet fait pivoter le bloc pivotant 12 vers le haut dans le sens du coincement c'est-à-dire que le début de ce mouvement amène le bord supérieur arrière du bloc pivotant 12 vers le haut contre 1 ' extrémité du bracelet q ' il force en coincement contre la paroi supérieure de la cavité réceptrice 22 et ceci par la traction transmise au bloc de maintien pivotant 12 à travers les picots 20 réalisant par le mouvement de pivotement arrière de celui-ci un véritable auto-maintien de chaque branche du bracelet. Le dégagement de l'extrémité 9 du bracelet 11 en vue de sa substitution par un bracelet différent s'effectue simplement et rapidement. Il suffit de basculer le bloc pivotant 12 vers l'avant. Ce mouvement provoque la libération de l'emprise des picots 20 par leur échappement des perforations par lesquelles ils maintenaient 1 ' extrémité 9 du bracelet . Cette extrémité se trouvant libérée dans la cavité réceptrice 22 peut s'extraire facilement par simple traction.A push on the bracelet towards the casing abuts its end against the bottom of the receiving cavity 22 of the receiving space 8. A pull on the branch of the bracelet swivels the pivoting block 12 upwards in the direction of wedging c ' that is to say that the beginning of this movement brings the upper rear edge of the pivoting block 12 upwards against the end of the bracelet q 'it forces in wedging against the upper wall of the receiving cavity 22 and this by the transmitted traction to the pivoting retaining block 12 through the pins 20 carrying out by the rear pivoting movement thereof a real self-retaining of each branch of the bracelet. The release of the end 9 of the strap 11 with a view to replacing it with a different strap is carried out simply and quickly. It suffices to tilt the pivoting block 12 forwards. This movement releases the grip of the pins 20 by their escape from the perforations through which they held the end 9 of the bracelet. This end being released in the receiving cavity 22 can be easily extracted by simple traction.
La pose d'un nouveau bracelet s'effectue tout aussi facilement par l'engagement de l'extrémité du bracelet dans la cavité réceptrice 22 avec mise en prise simultanée des picots 20 dans les perforations 21 existant à cet effet. Le basculement du bloc pivotant 12 avec poussée conjointe sur la branche du bracelet vers le boîtier assure sa mise en place définitive.The fitting of a new bracelet is carried out just as easily by the engagement of the end of the bracelet in the receiving cavity 22 with simultaneous engagement of the pins 20 in the perforations 21 existing for this purpose. The tilting of the pivoting block 12 with joint pushing on the branch of the bracelet towards the case ensures its final positioning.
Dans le cas du boîtier 1 particulier et monobloc représenté sur les figures, les picots ou tétons 20 sont dressés vers les segments tels que 23 séparant les ouvertures carrées 24 alignées en une rangée transversale à chacune des extrémités supérieures du boîtier 1. II apparaît évident que le mécanisme décrit et représenté peut se répéter à 1 ' identique à 1 ' autre extrémité du boîtier 1 pour 1 ' autre extrémité 25 de l'autre branche 26 du bracelet 11. In the case of the particular, one-piece housing 1 shown in the figures, the pins or nipples 20 are drawn towards the segments such as 23 separating the square openings 24 aligned in a transverse row at each of the upper ends of the housing 1. It appears obvious that the mechanism described and shown can be repeated at 1 identical to the other end of the case 1 for the other end 25 of the other branch 26 of the bracelet 11.
