Description

DISPOSITIF AUTOBLOQUANT ET ARTCICLE DE JOAILLERIE COMPORTANT LEDIT DISPOSITIF AUTOBLOATING AND ARTCICLE JEWELERY DEVICE COMPRISING SAID DEVICE
La présente invention a pour objet un dispositif autobloquant destiné à assembler solidairement deux éléments, ledit dispositif pouvant être incorporé notamment dans un article de joaillerie tel qu'une bague constituée d'un anneau et d'un élément décoratif interchangeable.The present invention relates to a self-locking device for assembling two elements integrally, said device can be incorporated in particular in a jewelery article such as a ring consisting of a ring and an interchangeable decorative element.
Plusieurs documents divulguant un système d'interchangeabilité pour bagues afin de faire varier son aspect esthétique font déjà partie de l'état de la technique. Les publications DE19734820 et JP9224724 dévoilent une bague dont l'anneau comporte un taraudage dans lequel vient se visser une tige d'un élément décoratif.Several documents disclosing an interchangeability system for rings to vary its aesthetic appearance are already part of the state of the art. The publications DE19734820 and JP9224724 disclose a ring whose ring has a tapping in which is screwed a rod of a decorative element.
L'inconvénient majeur de ce type d'assemblage provient du fait que la force qui lie l'élément décoratif à l'anneau dépend de la force avec laquelle cet élément décoratif a été vissé à l'anneau. Il n'est pas commode de trouver un juste équilibre qui assure à la fois une liaison sûre entre l'élément décoratif et l'anneau et une interchangeabilité aisée de ces éléments décoratifs.The major disadvantage of this type of assembly comes from the fact that the force that binds the decorative element to the ring depends on the strength with which this decorative element has been screwed to the ring. It is not convenient to find a proper balance that ensures both a secure connection between the decorative element and the ring and easy interchangeability of these decorative elements.
En effet, si une force trop grande est exercée sur l'élément décoratif lorsque celui-ci est vissé sur l'anneau, il ne sera pas toujours facile d'interchanger le motif. Une force bien trop grande devra être exercée sur l'élément décoratif, ce qui pourrait occasionner des dommages à celui-ci. A l'inverse, si la force exercée sur l'élément n'est pas suffisante, l'élément décoratif risque de se dévisser ce qui peut entraîner la perte de celui-ci.Indeed, if a too great force is exerted on the decorative element when it is screwed on the ring, it will not always be easy to interchange the pattern. Too much force should be exerted on the decorative element, which could cause damage to it. Conversely, if the force exerted on the element is not sufficient, the decorative element may be unscrewed which may result in the loss thereof.
Le but de la présente invention est de proposer un dispositif autobloquant simple destiné à assembler deux éléments, notamment dans le domaine de la joaillerie, ce dispositif ayant la particularité d'exercer une force constante entre les deux éléments lorsqu'il est verrouillé.The object of the present invention is to provide a simple self-locking device for assembling two elements, particularly in the field of jewelery, this device having the particularity of exerting a constant force between the two elements when locked.
Conformément à l'invention, ce but est atteint grâce à un dispositif autobloquant, destiné à assembler solidairement un premier et un deuxième élément, constitué d'un premier organe (1) solidaire ou susceptible d'être agencé solidairement au premier élément, d'un second organe (2) solidaire ou susceptible d'être agencé solidairement au deuxième élément et d'un joint (3). Le premier organe (1) comporte une partie cylindrique (4) et le second organe comporte un alésage (5) correspondant qui reçoit ladite partie cylindrique (4) de manière à pouvoir s'assembler par vissage au moyen d'au moins un filetage (6) agencé soit sur le contour externe de la partie cylindrique (4), soit sur l'alésage (5). Le joint (3) est agencé entre le premier et le second organe (1, 2) de manière à pouvoir être comprimé de part et d'autre par une partie de chaque organe (1, 2) lorsque ceux-ci sont assemblés par vissage. Au moins un ergot (8) est agencé sur l'un des deux organes (1, 2), ledit ergot (8) étant susceptible de s'introduire dans le filetage (6) de l'autre des deux organes (1, 2) et de se déplacer le long dudit filetage (6). Ce dernier comporte proche de l'une de ses extrémités une encoche (7) au niveau de laquelle l'ergot (8) est susceptible de s'aligner, puis d'être contraint, sous l'action de la force exercée par la dilatation du joint (3), de quitter le filet du filetage (6) et de venir se loger à l'intérieur de ladite encoche (7) verrouillant ainsi le dispositif.According to the invention, this object is achieved by means of a self-locking device, intended to solidarily assemble a first and a second element, consisting of a first member (1) integral or capable of being arranged integrally with the first element, a second member (2) integral or capable of being arranged integrally with the second element and a seal (3). The first member (1) has a cylindrical portion (4) and the second member has a corresponding bore (5) which receives said cylindrical portion (4) so that it can be screwed together by means of at least one thread ( 6) arranged either on the outer contour of the cylindrical portion (4) or on the bore (5). The seal (3) is arranged between the first and the second member (1, 2) so that it can be compressed on either side by a part of each member (1, 2) when they are assembled by screwing . At least one lug (8) is arranged on one of the two members (1, 2), said lug (8) being able to be introduced into the thread (6) of the other of the two members (1, 2). ) and to move along said thread (6). The latter comprises near one of its ends a notch (7) at which the lug (8) is capable of aligning and then being constrained, under the action of the force exerted by the expansion. of the seal (3), to leave the thread of the thread (6) and to be housed inside said notch (7) thus locking the device.

- La figure 4 représente un article de joaillerie pourvu du dispositif autobloquant sur lequel peuvent être agencés différents éléments décoratifs.- Figure 4 shows a jewelery article provided with the self-locking device on which can be arranged different decorative elements.
Selon le premier mode d'exécution de l'invention, le dispositif autobloquant, destiné à assembler solidairement un premier et un deuxième élément, lesquels peuvent être une bague et un élément décoratif tels qu'illustrés par la Figure 4, comprend un premier organe (1) dit organe mâle, solidaire du premier élément, un second organe (2) dit organe femelle, solidaire du second élément et un joint annulaire (3). L'organe mâle (1) comporte une partie cylindrique (4) et l'organe femelle (2) comporte un alésage (5).According to the first embodiment of the invention, the self-locking device, intended to integrally assemble a first and a second element, which may be a ring and a decorative element as illustrated in FIG. 4, comprises a first member ( 1) said male member secured to the first member, a second member (2) said female member integral with the second member and an annular seal (3). The male member (1) has a cylindrical portion (4) and the female member (2) has a bore (5).
L'une des extrémités de l'organe mâle (1) comprend une assise (9) sur laquelle est agencé le joint annulaire (3). Ce dernier fait généralement partie intégrante de l'organe mâle (1) puisqu'il est préférablement collé sur son assise (9).One end of the male member (1) comprises a seat (9) on which is arranged the annular seal (3). The latter is usually an integral part of the male member (1) since it is preferably bonded to its seat (9).
Un premier et un second ergot (8, 8') sont agencés à la même hauteur et à 180 degrés l'un de l'autre sur le contour externe de la partie cylindrique (4) de l'organe mâle (1) proche de l'une de ses extrémités. Ce premier et ce second ergot (8, 8') sont susceptibles de s'introduire respectivement dans un premier et un second filetage (6, 6') agencés sur l'alésage de l'organe femelle (2) afin que les deux organes (1, 2) puissent être assemblés par vissage. Les deux ergots (8, 8') sont préférablement de forme allongée et inclinés en correspondance avec l'angle des filets constituant les filetages (6, 6').A first and a second lug (8, 8 ') are arranged at the same height and 180 degrees from each other on the outer contour of the cylindrical portion (4) of the male member (1) close to one of its ends. This first and second lug (8, 8 ') are capable of being introduced into a first and a second thread (6, 6') respectively arranged on the bore of the female member (2) so as to that the two members (1, 2) can be assembled by screwing. The two lugs (8, 8 ') are preferably of elongated shape and inclined in correspondence with the angle of the threads constituting the threads (6, 6').
L'une des extrémités de chaque filetage (6, 6') de l'organe femelle (2) comporte une encoche ou évidements (7, 7') destiné à recevoir le premier et le second ergot (8, 8') afin de verrouiller les organes mâle et femelle (1 , 2) du dispositif autobloquant sous l'action du joint (3).One of the ends of each thread (6, 6 ') of the female member (2) has a notch or recesses (7, 7') for receiving the first and second lugs (8, 8 ') in order to locking the male and female members (1, 2) of the self-locking device under the action of the seal (3).
Selon les Figures 1a à 1d, l'assemblage des deux organes (1, 2) est obtenu par les séquences suivantes :According to FIGS. 1a to 1d, the assembly of the two members (1, 2) is obtained by the following sequences:
- positionnement de chaque ergot (8, 8') de l'organe mâle (1) respectivement dans l'autre extrémité de chaque filetage (6, 6') de l'organe femelle (2),positioning each pin (8, 8 ') of the male member (1) respectively in the other end of each thread (6, 6') of the female member (2),
- rotation axiale d'au moins 360 degrés de l'organe mâle (1) par rapport à l'organe femelle (2), l'une des extrémités de ce dernier comprimant ainsi le joint (3),axial rotation of at least 360 degrees of the male member (1) relative to the female member (2), one of the ends of the latter thus compressing the seal (3),
- alignement des deux ergots (8, 8') en correspondance avec les encoches (7,. T) de manière à ce que le verrouillage du dispositif est assuré par la dilatation du joint (3) poussant lesdits ergots (8, 8") dans leur encoche (7, T) respective les délogeant ainsi du dernier filet du filetage (6).- alignment of the two lugs (8, 8 ') in correspondence with the notches (7, T) so that the locking of the device is ensured by the expansion of the seal (3) pushing said lugs (8, 8 ") in their respective notch (7, T) thereby dislodging them from the last thread of the thread (6).
Dans la configuration où le dispositif est verrouillé, la force exercée par le joint sur l'organe femelle (2) empêche toute rotation de celui-ci puisque les deux extrémités de chaque ergot (8, 8') butent contre les flancs latéraux de chaque encoche (7, T).In the configuration where the device is locked, the force exerted by the seal on the female member (2) prevents any rotation thereof since the two ends of each lug (8, 8 ') abut against the lateral flanks of each notch (7, T).
Le désassemblage du premier et du second organe (1, 2) est susceptible d'être réalisé par une pression exercée sur au moins une des extrémités du dispositif. Une telle pression comprime le joint (3) de manière à désengager les deux ergots (8, 8') de leur encoche (7) respective et de les positionner à nouveau dans un des filets des filetages (6, 6') du second organe (2). Une rotation du premier organe (1) par rapport au second organe (2), doit ensuite être effectuée. Le nombre de tours nécessaires pour désassembler les deux organes (1, 2) correspond au nombre de filets constituant le filetage (6). La pression exercée sur le dispositif doit être maintenue au début de la rotation relative entre les deux organes (1 , 2).The disassembly of the first and second members (1, 2) can be achieved by a pressure exerted on at least one of the ends of the device. Such pressure compresses the seal (3) so as to disengage the two lugs (8, 8 ') from their respective notch (7) and position them at again in one of the threads of the threads (6, 6 ') of the second member (2). A rotation of the first member (1) relative to the second member (2) must then be performed. The number of turns required to disassemble the two members (1, 2) corresponds to the number of threads constituting the thread (6). The pressure exerted on the device must be maintained at the beginning of the relative rotation between the two members (1, 2).
Dans un deuxième mode d'exécution (Fig. 2, 2a et 2d), le premier organe (1) du dispositif autobloquant possède une partie cylindrique (4) comportant un filetage (6) sur son contour externe. Le second organe (2) comporte un ergot (8) sur son contour interne proche de l'une de ses extrémités. Le diamètre interne de l'autre de ses extrémités est légèrement inférieur au diamètre de la partie cylindrique (4) afin de créer une assise (9) sur laquelle le joint (3) est collé. Le filetage (6) du premier organe (1) comporte proche de l'une de ses extrémités une encoche (7) en forme de coude destiné à recevoir l'ergot (8) sous l'action du joint (3) une fois que l'assemblage des deux organes (1, 2) ait été effectué par vissage.In a second embodiment (FIG 2, 2a and 2d), the first member (1) of the self-locking device has a cylindrical portion (4) having a thread (6) on its outer contour. The second member (2) has a lug (8) on its inner contour near one of its ends. The inner diameter of the other of its ends is slightly smaller than the diameter of the cylindrical portion (4) to create a seat (9) on which the seal (3) is glued. The thread (6) of the first member (1) has, near one of its ends, a notch (7) in the shape of an elbow intended to receive the pin (8) under the action of the seal (3) once the two members (1, 2) have been assembled by screwing.
Dans un troisième mode d'exécution, (Fig. 3, 3a à 3c), le second organe (2) est en forme de capuchon au fond duquel est agencé le joint (3). Cet organe (2) est pourvu de deux ergots (5) proche de l'une de ses extrémités sur sa périphérie interne. Le premier organe (1 ) est une tige comportant un filetage (6) dont l'extrémité du dernier filet comporte une encoche (7) en forme de coude dans laquelle l'un des ergots (5) se positionne lors du verrouillage du dispositif.In a third embodiment, (FIG 3, 3a to 3c), the second member (2) is cap-shaped at the bottom of which is arranged the seal (3). This member (2) is provided with two lugs (5) close to one of its ends on its inner periphery. The first member (1) is a rod having a thread (6) whose end of the last thread comprises a notch (7) in the form of a bend in which one of the lugs (5) is positioned during the locking of the device.
Ainsi, la force devant être exercée sur le dispositif pour assembler ou désassembler les deux organes (1, 2) est toujours la même et dépend uniquement des caractéristiques du joint (3). Différent types de joint peuvent être utilisés afin de varier la force nécessaire pour l'assemblage et désassembiage desdits organes (1, 2).Thus, the force to be exerted on the device to assemble or disassemble the two members (1, 2) is always the same and depends only on the characteristics of the seal (3). Different types of joint can be used to vary the force required for the assembly and disassembly of said members (1, 2).
Le filetage (6) peut comporter N filets afin de devoir effectuer N tours avant le verrouillage du dispositif. L'un des deux organes (1, 2) peut également comporter un nombre quelconque de filetage (6), chacun d'entre eux étant susceptible de recevoir un ergot (8).The thread (6) may have N threads in order to have N turns before locking the device. One of the two organs (1, 2) can also have any number of threads (6), each of them being capable of receiving a lug (8).
