Description

Système de sécurité pour chaînes, colliers, bracelets Security system for chains, necklaces, bracelets
La présente invention concerne un dispositif de sécurité pour boucle ( chaîne, bracelet, collier, anse ...) de bijouterie joaillerie et maroquinerie. La fermeture d'une boucle est traditionnellement résolue par un mousqueton comportant un anneau fendu, or cet anneau fendu n'est jamais mécaniquement fermé mais simplement obstrué ou refermé par rapprochement de ses extrémités.The present invention relates to a safety device for a buckle (chain, bracelet, necklace, handle, etc.) in jewelry and leather goods. The closing of a loop is traditionally resolved by a carabiner comprising a split ring, but this split ring is never mechanically closed but simply obstructed or closed by bringing its ends together.
Il en résulte différents points de faiblesse suivant les modèles : Dans tous les cas, la fermeture, même neuve, résiste très mal en traction puisqu'étant, de principe, en anneau de type ouvert. Dans le cas d'un mousqueton dont le crochet est fermé par une bascule, la résistance est améliorée mais le passage pour l'anneau libre limité.This results in various points of weakness depending on the model: In all cases, the closure, even new, resists very poorly in traction since, in principle, being an open type ring. In the case of a carabiner whose hook is closed by a rocker, the resistance is improved but the passage for the free ring is limited.
Dans le cas d'un anneau télecopique rétractable, la faible épaisseur des pièces rend l'objet très sensible à l'usure puisque celle-ci s'applique justement sur l'endroit déjà faible de conception. Il peut facilement s'en suivre une ouverture accidentelle et donc la perte de la boucle.In the case of a retractable telescopic ring, the small thickness of the parts makes the object very sensitive to wear since it precisely applies to the already weak place of design. It can easily follow an accidental opening and therefore the loss of the loop.
De plus et dans tous les cas, l'installation de la boucle d'un collier est une opération désagréable puisqu'elle s'effectue sans vision en maintenant ouvertes de toutes petites pièces.In addition and in all cases, the installation of the loop of a collar is an unpleasant operation since it is carried out without vision by keeping open very small parts.
Suivant notre recherche, il semble n'exister, ni dans l'état de l'art ni dans les brevets, aucun système palliant les différents inconvénients précités. Le dispositif selon l'invention permet de remédier à ces difficultés.According to our research, there does not seem to exist, either in the state of the art or in patents, any system which overcomes the various aforementioned drawbacks. The device according to the invention overcomes these difficulties.
En effet, il est à la fois fiable, facile et rapide d'installation, et permet de créer une liaison d'une résistance au moins égale à celle de la boucle ( chaîne, bracelet collier, ou anse ) ainsi équipée.Indeed, it is both reliable, easy and quick to install, and makes it possible to create a connection with a resistance at least equal to that of the loop (chain, bracelet bracelet, or handle) thus equipped.
Il est essentiellement composé ( Planche 1 ) d'un bâti (1 ) de forme oblongue, creux, portant, dans un mode de réalisation, deux axes de révolution servant de pivots recevant pour l'un (P1 ) situé à l'intérieur du bâti une gâchette (2) rappelée par un ressort (3), l'autre (P2) situé à la périphérie du bâti une bascule (4). Le creux du bâti est fermé par une plaque (5) qui lui est solidarisée . La gâchette et la bascule se meuvent en rotation dans le même plan de l'épaisseur du creux du bâti, toutes deux selon des arcs limités pour chacune de la position verrouillage (fig. 1 ) à celle de pleine ouverture (fig. 2).It is essentially composed (Plate 1) of a frame (1) of oblong, hollow shape, carrying, in one embodiment, two axes of revolution serving as pivots receiving for one (P1) located inside the frame a trigger (2) returned by a spring (3), the other (P2) located at the periphery of the frame a rocker (4). The hollow of the frame is closed by a plate (5) which is secured to it. The trigger and the rocker move in rotation in the same plane of the thickness of the hollow of the frame, both according to arcs limited for each of the locking position (fig. 1) to that of full opening (fig. 2).
Dans sa version de base, la gâchette intègre trois fonctions : une fonction de verrou primaire mâle assuré par un pêne (6) venant se loger dans l'évidement (7) de l'extrémité libre du U de la bascule, une fonction de verrou secondaire assuré par un pêne (8) femelle venant recevoir le pêne (9) du talon de la bascule, une fonction de déverrouillage de la bascule grâce à un bouton (10) saillant du bâti au delà du talon de la bascule.In its basic version, the trigger incorporates three functions: a male primary lock function provided by a bolt (6) which is housed in the recess (7) of the free end of the U of the rocker, a lock function secondary provided by a female bolt (8) coming to receive the bolt (9) of the heel of the rocker, a function of unlocking of the scale using a button (10) projecting from the frame beyond the heel of the scale.
En passant de l'ouverture à la fermeture, le pêne (6) vient s'enfiler dans l'évidement (7) de l'extrémité libre du U de la bascule en même temps que le pêne mâle (7) du talon de la bascule vient s'engager dans l'élément femelle (8) de la gâchette (fig. 1 ).Passing from opening to closing, the bolt (6) is threaded into the recess (7) of the free end of the U of the rocker at the same time as the male bolt (7) of the heel of the rocker engages in the female element (8) of the trigger (fig. 1).
Un système à ressort (1 1 ) assure à la gâchette une position de repos en fermeture verrouillée. La bascule et le bâti forment alors un anneau mécaniquement fermé dont la solidité n'est quasiment limité que par l a résistance à la traction pure du ou des matériaux utilisés.A spring system (1 1) ensures the trigger a rest position in locked closure. The scale and the frame then form a mechanically closed ring whose solidity is almost limited only by the pure tensile strength of the material or materials used.
La plaque de fermeture (5) peut utilement, et à moindre coût, comporter une personnalisation ( dénomination commerciale et/ou décor ) de même que le bâti. Tant le bâti que la bascule et le couvercle peuvent facilement reprendre des formes personnalisées, voire suivre des modèles déposés, propres à chaque incorporateur. Tout ou partie des pièces constitutives peuvent être revêtues d'un matériau d'apprêt.The closure plate (5) can usefully, and at a lower cost, include personalization (trade name and / or decor) as well as the frame. Both the frame, the rocker and the cover can easily take on personalized shapes, or even follow registered models, specific to each incorporator. All or part of the constituent parts can be coated with a finishing material.
Le dispositif est aisément réalisable en tout métal ou alliage, précieux ou non, par un procédé classique ( cire perdue, frittage, estampage ...) ou moderne : injection de poudre plastifiée sous pression plus cuisson ( "M.I.M." ) par exemple.The device can easily be made of any metal or alloy, precious or not, by a conventional process (lost wax, sintering, stamping ...) or modern: injection of plasticized powder under pressure plus cooking ("M.I.M.") for example.
Selon des modes particuliers de réalisation ( planche 2 ) :According to particular embodiments (plate 2):
Les pivots de la bascule et de la gâchette sont remplacés par tout mode d'articulation procurant le même résultat.The pivots of the rocker and the trigger are replaced by any mode of articulation providing the same result.
Le ressort (3) est un ressort épingle à segments droits ( Fig. 1 ). Le pêne mâle du verrou primaire de la gâchette comporte un chanfrein (1 1 ) assurant son entrée automatique dans l'évidement de l'extrémité libre de la bascule et donc la fermeture de l'anneau et le verrouillage de la bascule d'une seule main.The spring (3) is a pin spring with straight segments (Fig. 1). The male latch of the primary trigger lock comprises a chamfer (1 1) ensuring its automatic entry into the recess of the free end of the rocker and therefore closing the ring and locking the rocker in one hand.
Le bâti comporte un troisième axe de révolution ( 1 2) servant de pivot à un levier (1 3) s'intégrant le long du corps du bâti jusqu'à condamner l'ouverture de la gâchette. Accessoirement, il peut également servir de support à la plaque de fermeture (5).The frame has a third axis of revolution (1 2) serving as a pivot for a lever (1 3) integrating along the body of the frame until the opening of the trigger is blocked. Incidentally, it can also serve as a support for the closure plate (5).
Le bâti est lié à la boucle par solidarisation directe ( soudure ...) ou par articulation ( charnière ...) ou par un système d'émerillon lui évitant tout défaut en torsion et en tombé.The frame is linked to the loop by direct connection (welding ...) or by articulation (hinge ...) or by a swivel system avoiding any defect in torsion and falling.
La gâchette intègre avec le talon de la bascule une quatrième fonction : le dispositif devient bistable, soit pleine ouverture soit verrouillage, en remplaçant l'élément de verrouillage femelle par un système double mâle en opposition. Les deux faces (B1 ) et (B2) du talon de la bascule s'opposent alors respectivement aux deux facesThe trigger integrates with the heel of the rocker a fourth function: the device becomes bistable, either full opening or locking, by replacing the female locking element with a double male system in opposition. The two faces (B1) and (B2) of the heel of the rocker then oppose respectively the two faces
(G1 ) et (G2) du talon de la gâchette. La forme de ces deux talons, coté bascule et coté gâchette, préférentiellement triangulaire permet cependant le passage en légère force de la position grand ouvert à la position verrouillage, mais non l'inverse, par le jeu des courbures : la position grand ouvert est obtenue par le couple concave coté gâchette convexe coté bascule, tandis que la position verrouillée est obtenue par le couple convexe coté gâchette concave coté bascule.(G1) and (G2) of the heel of the trigger. The shape of these two heels, rocker side and trigger side, preferably triangular allows however, the slight change in force from the wide open position to the locked position, but not the reverse, by the play of curvatures: the wide open position is obtained by the concave torque on the convex trigger side on the rocker side, while the locked position is obtained by the convex torque on the concave trigger side on the rocker side.
Le dispositif selon l'invention est particulièrement destiné comme fermoir de boucle que ce soit une chaîne un bracelet ou un collier de bijouterie, une anse de maroquinerie. The device according to the invention is particularly intended as a buckle clasp, whether it is a chain, a bracelet or a necklace of jewelry, a handle for leather goods.
