The latter ring is articulated on the former ring by utilizing a connecting spring (19) to press the latter ring against the former ring and to urge the latter ring slidingly to blocking position. The ring is totally molded from casting in coating made of plastic material.

Description

Domaine technique de l'inventionTechnical field of the invention

L'invention est relative à une boucle d'attache pour la mise en place et le réglage d'une sangle, composée d'une paire d'anneaux superposés présentant des cadres rectangulaires de dimensions différentes, le premier anneau le plus grand comportant une première ouverture rectangulaire disposée sous une deuxième ouverture rectangulaire ménagée dans le deuxième anneau de taille plus réduite, de manière à définir une fente transversale de passage de la sangle, la fente étant agencée entre l'une des arêtes extérieures du deuxième anneau, et le côté adjacent de la première ouverture du premier anneau, la boucle se trouvant soit dans une position de blocage de la sangle dans la fente suite à l'application d'une force de serrage, soit dans une position de déblocage après un mouvement de basculement du deuxième anneau provoquant une augmentation de la zone de passage dans la fente.The invention relates to an attachment loop for setting up and adjusting a strap, composed of a pair of superposed rings having rectangular frames of different dimensions, the first largest ring having a first rectangular opening arranged under a second rectangular opening in the second ring of smaller size, so as to define a transverse slot passage of the strap, the slot being arranged between one of the outer edges of the second ring, and the adjacent side the first opening of the first ring, the loop being either in a locking position of the strap in the slot following the application of a clamping force, or in a release position after a tilting movement of the second ring causing an increase in the passage area in the slot.

État de la techniqueState of the art

Selon la boucle décrite dans le document EP 614626 , le deuxième anneau est monté flottant sur le premier anneau, et y est retenu par une boucle de sangle cousue entourant les deux traverses arrière des anneaux. L'autre bout de sangle est coincé dans la fente entre les deux anneaux dès l'application d'une force de traction. Lorsque la sangle ne se trouve plus sous tension, l'effet de coincement disparaît, et la sangle peut alors coulisser dans la fente, notamment en cas de poussée sur l'extrémité de la sangle. Pour éviter ce déréglage involontaire de la boucle d'attache, il est alors nécessaire de remettre la sangle sous tension en tirant sur l'extrémité libre de la sangle.According to the loop described in the document EP 614626 , the second ring is mounted floating on the first ring, and is retained by a loop of sewn strap surrounding the two rear crosses of the rings. The other end of the strap is stuck in the slot between the two rings as soon as the application of a pulling force. When the strap is no longer under tension, the wedging effect disappears, and the strap can then slide in the slot, especially when pushing on the end of the strap. To avoid this unintentional adjustment of the fastening loop, it is then necessary to re-tension the strap by pulling on the free end of the strap.

Selon une autre boucle d'attache connue, le deuxième anneau supérieur est guidé en translation le long des chants opposés de l'anneau inférieur, et est poussé par des moyens élastiques vers la position de blocage. Le coulissement du deuxième anneau rend impossible l'ouverture totale de la boucle, ce qui limite la section de passage d'une sangle munie d'une butée d'extrémité.According to another known fastening loop, the second upper ring is guided in translation along the opposite edges of the lower ring, and is pushed by elastic means to the locking position. The sliding of the second ring makes it impossible to open the loop completely, which limits the passage section of a strap provided with an end stop.

Objet de l'inventionObject of the invention

L'objet de l'invention consiste à réaliser une boucle d'attache ayant un blocage optimum de la sangle évitant tout déréglage intempestif, et permettant d'obtenir une grande ouverture pour la mise en place de la sangle.The object of the invention is to provide a fastening loop having an optimum locking of the strap avoiding inadvertent adjustment, and to obtain a large opening for the introduction of the strap.

Le dispositif selon l'invention est caractérisé en ce que le deuxième anneau supérieur est articulé au premier anneau inférieur au moyen d'un ressort de liaison apte à plaquer le deuxième anneau contre le premier anneau, et à solliciter ledit deuxième anneau à coulissement vers la position de blocage.The device according to the invention is characterized in that the second upper ring is articulated to the first lower ring by means of a connecting spring adapted to press the second ring against the first ring, and to urge said second ring to slide towards the first ring. blocking position.

L'effet de pincement est déterminé pour éviter le déblocage lorsque la sangle n'est plus sous tension, tout en autorisant une possibilité de glissement lorsqu'on tire sur l'extrémité de la sangle pour le réglage. L'introduction de la sangle dans la boucle est facilitée grâce au débattement important du deuxième anneau par rapport au premier anneau.The pinch effect is determined to prevent unlocking when the strap is no longer energized, while allowing a possibility of sliding when pulling the end of the strap for adjustment. The introduction of the strap in the loop is facilitated by the large clearance of the second ring relative to the first ring.

Selon un mode de réalisation préférentiel, le ressort de liaison est formé par un ressort hélicoïdal traversant un orifice médian du deuxième anneau, ledit ressort étant accroché par ses deux extrémités opposées au premier anneau. Le ressort hélicoïdal s'étend dans la direction transversale de l'axe de basculement du deuxième anneau.According to a preferred embodiment, the connecting spring is formed by a helical spring passing through a median orifice of the second ring, said spring being hooked by its two opposite ends to the first ring. The coil spring extends in the transverse direction of the tilting axis of the second ring.

De préférence, l'orifice de passage du ressort de liaison est agencé dans une protubérance à l'extérieur de l'ouverture du deuxième anneau, ladite protubérance s'étendant dans la direction de coulissement du deuxième anneau vers la position de blocage.Preferably, the passage opening of the connecting spring is arranged in a protuberance outside the opening of the second ring, said protuberance extending in the sliding direction of the second ring to the locking position.

Description d'un mode préférentiel de l'inventionDescription of a preferred embodiment of the invention

Sur les figures 1 à 3, une boucle 10 d'attache réglable est composée d'une paire d'anneaux 11, 12 superposés ayant des structures rectangulaires ou trapézoïdales de dimensions différentes. Le premier anneau 11 le plus grand, comporte une première ouverture 13 disposée sous une deuxième ouverture 14 rectangulaire ménagée dans le deuxième anneau 12 de taille plus réduite.On the Figures 1 to 3 an adjustable fastening loop 10 is composed of a pair of superposed rings 11, 12 having rectangular or trapezoidal structures of different sizes. The first ring 11 the largest, has a first opening 13 disposed under a second rectangular opening 14 formed in the second ring 12 of smaller size.

La largeur de la sangle 15 est légèrement inférieure à celle des ouvertures 13, 14 pour éviter tout frottement de la sangle 15 contre les bords latéraux opposés des anneaux 11, 12.The width of the strap 15 is slightly less than that of the openings 13, 14 to avoid any friction of the strap 15 against the opposite lateral edges of the rings 11, 12.

En référence à la figure 3, la sangle 15 traverse les deux ouvertures 13, 14 et l'extrémité de la sangle 15 est ensuite insérée dans une fente 16 transversale située entre l'arête extérieure 17 du deuxième anneau 12, et le côté adjacent de la première ouverture 13. Elle retraverse ensuite en sens opposé le premier anneau 11 en formant une spire autour de la traverse 18 de droite du deuxième anneau 12.With reference to the figure 3 , the strap 15 passes through the two openings 13, 14 and the end of the strap 15 is then inserted into a transverse slot 16 located between the outer edge 17 of the second ring 12, and the adjacent side of the first opening 13. It then reverses in the opposite direction the first ring 11 by forming a turn around the right crossbar 18 of the second ring 12.

Le deuxième anneau 12 supérieur est articulé au premier anneau 11 inférieur au moyen d'un ressort de liaison 19, lequel est agencé pour plaquer le deuxième anneau 12 contre la face supérieure du premier anneau 11, et pour solliciter le deuxième anneau 12 selon un mouvement de coulissement vers la position de blocage pour le coincement de la sangle 15 dans la fente 16.The second upper ring 12 is articulated to the first lower ring 11 by means of a connecting spring 19, which is arranged to press the second ring 12 against the upper face of the first ring 11, and to urge the second ring 12 in a motion sliding towards the locking position for the jamming of the strap 15 in the slot 16.

Le ressort de liaison 19 est formé à titre d'exemple par un ressort hélicoïdal traversant un orifice 20 médian ménagé dans une protubérance 23 du deuxième anneau 12. Le ressort hélicoïdal est accroché par ses deux extrémités dans des encoches 21, 22 opposées du premier anneau 11 de manière à constituer l'axe d'articulation du deuxième anneau 12. La déformation élastique du ressort hélicoïdal autorise également une petite course de coulissement du deuxième anneau 12 lors du blocage de la sangle 15.The connecting spring 19 is formed by way of example by a helical spring passing through a median orifice 20 formed in a protuberance 23 of the second ring 12. The coil spring is hooked by its two ends in notches 21, 22 opposite the first ring 11 so as to form the axis of articulation of the second ring 12. The elastic deformation of the coil spring also allows a small sliding stroke of the second ring 12 when locking the strap 15.

La figure 2 montre la décomposition des forces appliquées sur le deuxième anneau 12 par le ressort de liaison 19, lequel n'est pas représenté pour des raisons de clarté du dessin. Les deux forces élémentaires de traction F1 et F2 exercées par le ressort hélicoïdal 19 sur la protubérance 23 du deuxième anneau 12 engendre une première composante Fx pour le mouvement de coulissement vers la position de blocage, et une deuxième composante Fz destinée à plaquer le deuxième anneau 12 contre le premier anneau 11.The figure 2 shows the decomposition of the forces applied on the second ring 12 by the connecting spring 19, which is not shown for the sake of clarity of the drawing. The two elementary tensile forces F1 and F2 exerted by the helical spring 19 on the protuberance 23 of the second ring 12 generates a first component F x for the sliding movement towards the locking position, and a second component F z intended to press the second ring 12 against the first ring 11.

Le fonctionnement de la boucle 10 selon l'invention est le suivant :The operation of the loop 10 according to the invention is as follows:

Sur la figure 4, la boucle 10 est fermée, et le brin de sangle 15 de droite est coincé dans la fente 16. Une force de traction T1 exercée sur la sangle 15 provoque le coulissement du deuxième anneau 12 vers la position de blocage. Cet état de coincement subsiste même lorsque la sangle n'est plus sous tension, grâce à la première composante Fx du ressort de liaison 19 qui inhibe tout déblocage involontaire de la boucle 10. Le coincement de la sangle 15 reste néanmoins suffisamment modéré pour permettre le glissement de la sangle dans la fente 16 lorsqu'on tire sur la butée 24 d'extrémité de la sangle en T2 pour son réglage.On the figure 4 the buckle 10 is closed, and the right strap strand 15 is wedged in the slot 16. A pulling force T1 exerted on the strap 15 causes the second ring 12 to slide to the locking position. This jamming state remains even when the strap is no longer under tension, thanks to the first component F x of the connecting spring 19 which inhibits unintentional release of the buckle 10. The wedging of the strap 15 remains nevertheless moderate enough to allow the sliding of the strap in the slot 16 when pulling on the end stop 24 of the strap in T2 for its adjustment.

Sur la figure 5, la boucle 10 est en cours d'ouverture après soulèvement du deuxième anneau 12 dans le sens de la flèche F3. Le mouvement de pivotement du deuxième anneau 12 s'effectue autour de l'axe d'articulation du ressort 19 hélicoïdal, et l'extrémité du deuxième anneau 12 reste en appui contre le premier anneau 11. La sangle 15 est décoincée et peut être déplacée librement dans la boucle 10.On the figure 5 , the loop 10 is being opened after lifting the second ring 12 in the direction of the arrow F3. The pivoting movement of the second ring 12 takes place around the axis of articulation of the helical spring 19, and the end of the second ring 12 remains in support. against the first ring 11. The strap 15 is loosened and can be moved freely in the loop 10.

Sur la figure 6, la boucle 10 se trouve en pleine ouverture lorsque le deuxième anneau 12 s'étend perpendiculairement au premier anneau 11. II en résulte un grand passage pour dégager ou engager la butée 24 d'extrémité de la sangle 15, et la deuxième composante Fz du ressort 19 maintient l'extrémité du deuxième anneau 12 contre le premier anneau 11.On the figure 6 the loop 10 is fully open when the second ring 12 extends perpendicularly to the first ring 11. This results in a large passage to release or engage the end stop 24 of the strap 15, and the second component F z of the spring 19 keeps the end of the second ring 12 against the first ring 11.

Les figures 7-9 montrent un exemple de réalisation de la boucle 10, avec le deuxième anneau 12 surmoulé totalement dans un enrobage 25 en matière plastique. Les deux branches du ressort de liaison 19 hélicoïdal s'étendent transversalement avec jeu dans une cavité 26 prévue à la partie arrière de l'enrobage 25 pour permettre la déformation du ressort lors du blocage de la sangle 15. L'enrobage autour de la traverse 18 est conformé selon un plot 27 susceptible de pénétrer totalement dans la première ouverture 13 du premier anneau 11 lorsque la sangle est bloquée comme à la figure 4. Le deuxième anneau 12 est alors en appui complet sur le premier anneau 11.The Figures 7-9 show an embodiment of the loop 10, with the second ring 12 completely overmolded in a coating 25 of plastic. The two branches of the helical connecting spring 19 extend transversely with clearance in a cavity 26 provided at the rear part of the coating 25 to allow the deformation of the spring during the locking of the strap 15. The coating around the sleeper 18 is shaped according to a stud 27 capable of penetrating completely into the first opening 13 of the first ring 11 when the strap is locked as in the figure 4 . The second ring 12 is then in full support on the first ring 11.

Il est clair que le ressort de liaison 19 hélicoïdal de la boucle 10 peut être remplacé par tout autre type de ressort équivalent.It is clear that the helical link spring 19 of the loop 10 can be replaced by any other type of equivalent spring.
