Description

Domaine techniqueTechnical area

L'invention est relative à un dispositif de réglage et de serrage d'une sangle et à un harnais d'encordement comportant un tel dispositif de réglage et de serrage d'une sangle.The invention relates to a device for adjusting and tightening a strap and to a tying harness comprising such a device for adjusting and tightening a strap.

Technique antérieurePrior art

Il est connu de régler les différentes sangles d'un harnais d'encordement au moyen d'un dispositif de réglage qui comporte une boucle. Le dispositif de régale est muni d'une boucle et est configuré pour réaliser le réglage de la sangle à la longueur choisie puis le serrage de la sangle à ladite longueur afin que l'utilisateur puisse travailler dans les meilleures conditions.It is known to adjust the various straps of a tying harness by means of an adjustment device which comprises a buckle. The regale device is provided with a buckle and is configured to adjust the strap to the chosen length and then tighten the strap to said length so that the user can work in the best conditions.

Différentes configurations de dispositif de réglage et de serrage ont été testées et utilisées. Il est possible de citer les dispositifs présentés dans les documents US 5,432,984 , US 8,381,366 , FR 2996732 et US 9,433,260 . De manière générale, le dispositif de réglage et de serrage est formé par deux anneaux superposés et de forme rectangulaire. Ces deux anneaux possèdent des dimensions différentes.Various adjuster and clamp configurations have been tested and used. It is possible to cite the devices presented in the documents US 5,432,984 , US 8,381,366 , FR 2996732 and US 9,433,260 . In general, the adjustment and clamping device is formed by two superimposed rings of rectangular shape. These two rings have different dimensions.

L'anneau inférieur est plus grand que l'anneau supérieur. Les deux anneaux sont agencés afin de définir une fente de passage de la sangle entre les deux anneaux. Les deux anneaux sont montés mobiles l'un par rapport à l'autre de manière à pouvoir moduler la largeur de la fente de passage. La sangle passe autour de l'anneau supérieur. La mise sous tension de la boucle de sangle se traduit par la fermeture de la fente de passage qui bloque la sangle dans la position désirée.The lower ring is larger than the upper ring. The two rings are arranged in order to define a slot for the passage of the strap between the two rings. The two rings are mounted to be movable relative to each other so as to be able to modulate the width of the passage slot. The strap goes around the top ring. The tensioning of the strap buckle results in the closing of the passage slot which locks the strap in the desired position.

Cependant, à l'usage lorsque la sangle est sous contrainte, il s'avère qu'il est de plus en plus difficile d'avoir un dispositif de réglage qui assure également un blocage de la sangle dans la position. Il s'avère qu'avec l'usure de la sangle son état de surface évolue de sorte que les frottements entre les anneaux et la sangle ne sont plus suffisants pour empêcher le glissement de la sangle. Même s'il est toujours possible de conformer l'anneau inférieur afin de présenter une arête rugueuse qui assure un niveau de frottement suffisant pour assurer un bon maintien de la sangle, cette solution n'est pas acceptable car cela va induire une usure accélérée de la sangle dans la zone de frottement ce qui sera interprétée par l'utilisateur comme une usure prématurée synonyme d'une sangle de faible qualité ou endommagée.However, in use when the strap is under stress, it turns out to be more and more difficult to have an adjustment device which also ensures a locking of the strap in the position. It turns out that with the wear of the strap its surface condition changes so that the friction between the rings and the strap is no longer sufficient to prevent the strap from slipping. Even if it is always possible to conform the lower ring in order to present a rough edge which ensures a sufficient level of friction to ensure a good maintenance of the strap, this solution is not acceptable because it will induce an accelerated wear of the strap in the friction zone which will be interpreted by the user as premature wear synonymous with poor quality or damaged strap.

Il est donc nécessaire de trouver une autre solution permettant d'assurer un maintien efficace de la sangle dans la position désirée sous contrainte et moins sensible à l'évolution de l'état de surface de la sangle. Bien entendu, l'amélioration de la qualité du blocage ne doit pas se faire au détriment de la facilité du réglage.It is therefore necessary to find another solution making it possible to ensure effective maintenance of the strap in the desired position under stress and less sensitive to changes in the surface condition of the strap. Of course, improving the quality of the blocking should not come at the expense of ease of adjustment.

Objet de l'inventionObject of the invention

Un objet de l'invention consiste en un dispositif de réglage et de serrage d'une sangle qui est plus efficace que l'art antérieur sans pour autant dégrader la facilité de réglage de la sangle.An object of the invention consists of a device for adjusting and tightening a strap which is more efficient than the prior art without, however, degrading the ease of adjustment of the strap.

On tend à résoudre ce problème au moyen d'un dispositif de réglage selon les revendications annexées et notamment au moyen d'un dispositif de réglage et de serrage d'une sangle qui comporte un premier anneau et un deuxième anneau superposés pour définir une fente de passage de la sangle, le deuxième anneau venant en appui d'une surface supérieure du premier anneau, la fente de passage de la sangle étant délimitée par une arête extérieure du deuxième anneau et une arête intérieure du premier anneau. Le premier anneau et le deuxième anneau sont mobiles l'un par rapport à l'autre de sorte que la fente de passage de la sangle soit à épaisseur variable et que les premier et deuxième anneaux soient dans une position de blocage lors de la mise sous tension de la sangle ou soient dans une position de déblocage après un mouvement relatif entre les premier et deuxième anneaux provoquant une augmentation de l'épaisseur de la fente de passage.This problem tends to be solved by means of an adjustment device according to the appended claims and in particular by means of a device for adjusting and tightening a strap which comprises a first ring and a second ring superimposed to define a slit of passage of the strap, the second ring resting on an upper surface of the first ring, the strap passage slot being delimited by an outer edge of the second ring and an inner edge of the first ring. The first ring and the second ring are movable relative to each other so that the slot for the passage of the strap is of variable thickness and that the first and second rings are in a locked position when tensioning the strap or are in an unlocked position after relative movement between the first and second rings causing an increase in the thickness of the passage slot.

Le dispositif de réglage et de serrage est remarquable en ce qu'une surface inférieure du premier anneau opposée à la face supérieure du premier anneau possède une zone texturée munie de plusieurs éléments en saillie destinés à former une zone de frottement accrue entre la sangle et la surface inférieure du premier anneau, la zone texturée étant séparée de l'arête extérieure du deuxième anneau par la fente de passage de la sangle.The adjustment and tightening device is remarkable in that a lower surface of the first ring opposite the upper face of the first ring has a textured area provided with several protruding elements intended to form an area of increased friction between the strap and the strap. lower surface of the first ring, the textured area being separated from the outer edge of the second ring by the strap passage slot.

Dans un développement, le premier anneau possède un corps s'étendant selon une première direction. La surface inférieure est non plane et possède au moins des première et deuxième portions de surfaces qui sont non-parallèles et séparées par une zone d'inflexion. La zone texturée est formée sur la première portion de surface, le deuxième anneau venant en appui sur le premier anneau en vis-à-vis de la deuxième portion de surface, des première et deuxième portions de surfaces non-parallèles étant sécantes lorsqu'elles sont prolongées l'une vers l'autre.In one development, the first ring has a body extending in a first direction. The lower surface is non-planar and has at least first and second surface portions which are non-parallel and separated by a zone of inflection. The textured zone is formed on the first surface portion, the second ring resting on the first ring opposite the second surface portion, the first and second portions of non-parallel surfaces being intersecting when they are extended towards each other.

De manière avantageuse, le corps du premier anneau définit une forme en V ou en U dans un plan de coupe contenant la première direction. L'arête intérieure est prolongée par une des surfaces inclinées formant la forme en V ou en U.Advantageously, the body of the first ring defines a V or U shape in a section plane containing the first direction. The inner ridge is extended by one of the inclined surfaces forming the V or U shape.

Dans une configuration particulière, la première portion de surface inférieure définit un renfoncement orienté vers la surface supérieure, la zone texturée étant disposée entre l'arête intérieure et le renfoncement.In a particular configuration, the first lower surface portion defines a recess oriented towards the upper surface, the textured area being disposed between the interior ridge and the recess.

Dans un développement avantageux, la zone texturée possède des éléments en saillie configurés pour s'enfoncer dans la sangle.In an advantageous development, the textured area has protruding elements configured to sink into the strap.

Il est également intéressant de prévoir que les éléments en saillie sont disposés à une première distance de l'arête intérieure, la première distance étant non nulle et inférieure à deux fois l'épaisseur du premier anneau.It is also advantageous to provide that the projecting elements are arranged at a first distance from the inner ridge, the first distance being non-zero and less than twice the thickness of the first ring.

Préférentiellement, au moins une partie des éléments en saillie est formée par des picots.Preferably, at least part of the projecting elements is formed by pins.

Dans une autre configuration, au moins une partie des éléments en saillie est formée dans la masse du premier anneau.In another configuration, at least part of the projecting elements is formed in the mass of the first ring.

Il est encore avantageux de prévoir qu'au moins une partie des éléments en saillie est formée par un matériau surmoulé sur le premier anneau.It is also advantageous to provide that at least part of the projecting elements is formed by a material overmolded on the first ring.

Préférentiellement, au moins une partie des éléments en saillie est formée sur un support rapporté sur le premier anneau et installé démontable par rapport au premier anneau.Preferably, at least part of the projecting elements is formed on a support attached to the first ring and installed removable from the first ring.

Dans un mode de réalisation particulier, le support recouvre au moins partiellement la surface inférieure du premier anneau et forme un crochet recouvrant l'arête intérieure et une partie de la surface supérieureIn a particular embodiment, the support at least partially covers the lower surface of the first ring and forms a hook covering the inner ridge and part of the upper surface.

L'invention a également pour objet un système de serrage et de blocage qui est plus efficace que l'art antérieur sans pour autant dégrader la facilité de réglage de la sangle.The subject of the invention is also a tightening and locking system which is more effective than the prior art without, however, degrading the ease of adjustment of the strap.

Le système de réglage et de serrage est remarquable en ce qu'il comporte un dispositif de réglage et de serrage d'une sangle selon l'une des configurations précédentes et une sangle. La hauteur des éléments en saillie est inférieure ou égale à deux fois l'épaisseur de la sangle.The adjustment and tightening system is remarkable in that it comprises a device for adjusting and tightening a strap according to one of the preceding configurations and a strap. The height of the protruding elements is less than or equal to twice the thickness of the strap.

L'invention a également pour objet un harnais d'encordement dont au moins une des sangles de réglage est mieux maintenue dans la position bloquée que les configurations de l'art antérieur tout en restant facile à régler.The subject of the invention is also a tying-in harness, at least one of the adjustment straps of which is better maintained in the locked position than the configurations of the prior art while remaining easy to adjust.

Le harnais d'encordement est remarquable en ce qu'il comporte un système de réglage et de serrage selon la configuration précédenteThe roping harness is remarkable in that it has an adjustment and tightening system according to the previous configuration

Description des modes de réalisationDescription of the embodiments

Le dispositif de réglage et de serrage d'une sangle est principalement destiné à être monté sur un harnais d'encordement afin de pourvoir régler la longueur effective de la sangle et de bloquer cette sangle à la longueur effective recherchée.The device for adjusting and tightening a strap is mainly intended to be mounted on a tying harness in order to be able to adjust the effective length of the strap and to block this strap at the desired effective length.

La figure 1 illustre de manière schématique un harnais d'encordement 1 qui peut recevoir un ou plusieurs dispositifs de réglage et de serrage 2 d'une sangle. Comme illustré, le dispositif de réglage et de serrage 2 peut être monté pour régler la longueur de la bretelle droite, de la bretelle gauche, la ceinture disposée autour de la taille, le tour de cuisse droit ou le tour de cuisse gauche. Pour le réglage de la ceinture, un ou plusieurs dispositifs d'attache 2 peuvent être utilisés.The figure 1 schematically illustrates a tying harness 1 which can receive one or more adjustment and tightening devices 2 of a strap. As illustrated, the adjustment and tightening device 2 can be mounted to adjust the length of the right shoulder strap, the left shoulder strap, the belt disposed around the waist, the right thigh circumference or the left thigh circumference. For the adjustment of the belt, one or more fastening devices 2 can be used.

Comme illustré aux figures 2 et 3, le dispositif de réglage et de serrage 2 comporte un premier anneau 3 et un deuxième anneau 4 superposés l'un sur l'autre. Les deux anneaux 3 et 4 définissent chacun un trou traversant 5. Chaque anneau 3 et 4 possède un corps qui fait le tour du trou traversant 5 et possède des arêtes intérieures 3a/4a ainsi que des arêtes extérieures 3b/4b. Il est avantageux de former le premier anneau 3 et le deuxième anneau 4 dans un matériau métallique pour assurer la tenue mécanique du dispositif de réglage et de serrage 2 lors d'une chute.As shown in figures 2 and 3 , the adjustment and clamping device 2 comprises a first ring 3 and a second ring 4 superimposed on one another. The two rings 3 and 4 each define a through hole 5. Each ring 3 and 4 has a body which goes around the through hole 5 and has interior ridges 3a / 4a as well as exterior ridges 3b / 4b. It is advantageous to form the first ring 3 and the second ring 4 in a metallic material to ensure the mechanical strength of the adjustment and clamping device 2 during a fall.

Les deux anneaux 3 et 4 sont décalés l'un de l'autre pour définir une fente 6 de passage d'une sangle 7 qui doit pouvoir être réglée à la longueur recherchée et bloquée à la longueur imposée. Les deux anneaux 3 et 4 peuvent avoir une forme quelconque, il est possible d'avoir des formes externes rectangulaires, carrées, trapézoïdales. Il est même possible d'avoir des anneaux ayant des zones courbées.The two rings 3 and 4 are offset from each other to define a slot 6 for the passage of a strap 7 which must be able to be adjusted to the desired length and blocked at the imposed length. The two rings 3 and 4 can have any shape, it is possible to have rectangular, square or trapezoidal external shapes. It is even possible to have rings having curved areas.

La fente de passage 6 est délimitée d'une part par l'arête intérieure 3a du premier anneau 3 ainsi que par l'arête extérieure 4b du deuxième anneau 4 et plus particulièrement par l'arête intérieure 3a de la face inférieure du premier anneau 3 ainsi que par l'arête extérieure 4b de la face supérieure du deuxième anneau 4. Les deux anneaux 3 et 4 sont montés mobiles l'un par rapport à l'autre de manière à pourvoir moduler la largeur de la fente de passage 6 de la sangle 7 c'est-à-dire moduler la distance entre l'arête intérieure 3a du premier anneau 3 et l'arête extérieure 4b du deuxième anneau 4.The passage slot 6 is delimited on the one hand by the inner edge 3a of the first ring 3 as well as by the outer edge 4b of the second ring 4 and more particularly by the inner edge 3a of the lower face of the first ring 3 as well as by the outer edge 4b of the upper face of the second ring 4. The two rings 3 and 4 are mounted to be movable with respect to one another. the other so as to be able to modulate the width of the passage slot 6 of the strap 7, that is to say modulate the distance between the inner edge 3a of the first ring 3 and the outer edge 4b of the second ring 4 .

La forme du trou traversant 5 peut être quelconque. Il en va de même pour les formes extérieures du premier anneau 3 et du deuxième anneau 4 qui peuvent être quelconque. Cependant, il est avantageux que le trou traversant 5 du premier anneau 3 possède au moins une surface plane. Il est avantageux que la face externe du deuxième anneau 4 possède une surface plane. Il est alors possible de former une fente ayant deux parois opposées planes et avantageusement parallèles pour avoir une surface de contact maximale avec la sangle sur les deux faces opposées de la sangle selon son épaisseur. Dans son cheminement avec les anneaux 3 et 4, la sangle vient en contact de l'arête intérieure 3a de la face inférieure et de l'arête extérieure 4b de la face supérieure.The shape of the through hole 5 can be any. The same goes for the external shapes of the first ring 3 and of the second ring 4 which can be arbitrary. However, it is advantageous that the through hole 5 of the first ring 3 has at least one flat surface. It is advantageous that the outer face of the second ring 4 has a flat surface. It is then possible to form a slot having two opposite flat and advantageously parallel walls in order to have a maximum contact surface with the strap on the two opposite faces of the strap depending on its thickness. In its path with the rings 3 and 4, the strap comes into contact with the inner ridge 3a of the lower face and the outer ridge 4b of the upper face.

Il est particulièrement avantageux que l'arête intérieure inférieure 3a et l'arête extérieure supérieure 4b soient rectilignes et que la fente 6 possède une section rectangulaire ou sensiblement rectangulaire ce qui facilite le blocage de la sangle 7. La section de la fente 6 est observée avec deux surfaces opposées formées par l'arête intérieure 3a et l'arête extérieure 4b. La section est également définie par deux autres arêtes intérieures opposées du trou traversant 5 du premier anneau 3.It is particularly advantageous that the lower inner edge 3a and the upper outer edge 4b are rectilinear and that the slot 6 has a rectangular or substantially rectangular section which facilitates the locking of the strap 7. The section of the slot 6 is observed. with two opposing surfaces formed by the inner ridge 3a and the outer ridge 4b. The section is also defined by two other opposite interior ridges of the through hole 5 of the first ring 3.

Le premier anneau 3 peut se déplacer par rapport au deuxième anneau 4 de sorte que la largeur de la fente 6 soit inférieure ou égale à l'épaisseur de la sangle 7 pour bloquer la sangle 7 entre les deux anneaux. La sangle 7 s'étend selon une direction longitudinale qui correspond à la plus grande dimension de la sangle 7. La largeur et l'épaisseur de la sangle 7 sont mesurées selon des directions perpendiculaires en elles et perpendiculaires à la direction longitudinale. La largeur correspond à une dimension supérieure à l'épaisseur. La largeur de la fente 6 est mesurée selon le même axe que l'épaisseur de la sangle 7.The first ring 3 can move relative to the second ring 4 so that the width of the slot 6 is less than or equal to the thickness of the strap 7 to block the strap 7 between the two rings. The strap 7 extends in a longitudinal direction which corresponds to the largest dimension of the strap 7. The width and the thickness of the strap 7 are measured in directions perpendicular to them and perpendicular to the longitudinal direction. The width corresponds to a dimension greater than the thickness. The width of the slot 6 is measured along the same axis as the thickness of the strap 7.

Chaque anneau 3/4 s'étend selon une direction AA et possède des première et seconde extrémités opposées selon ladite direction. La première extrémité des deux anneaux coopère avec la sangle 7 pour assurer le réglage et le serrage de la sangle 7 à la longueur désirée. La deuxième extrémité des deux anneaux est associée à un point de fixation, par exemple la deuxième extrémité de la sangle 7 ou un point d'ancrage du harnais d'encordement 1. Les deux anneaux 3 et 4 sont maintenus solidaires, par exemple au moyen d'une boucle de sangle ou tout autre moyen de solidarisation à la deuxième extrémité.Each 3/4 ring extends in a direction AA and has first and second opposite ends in said direction. The first end of the two rings cooperates with the strap 7 to ensure the adjustment and tightening of the strap 7 to the desired length. The second end of the two rings is associated with an attachment point, for example the second end of the strap 7 or an anchoring point of the tying harness 1. The two rings 3 and 4 are held together, for example by means a strap loop or any other securing means at the second end.

Le premier anneau 3 peut se déplacer par rapport au deuxième anneau 4 en translation et en rotation pour moduler l'épaisseur de la fente 6. Le deuxième anneau 4 possède une surface inférieure qui est en appui sur une surface supérieure du premier anneau 3. Lors de la mise sous tension de la sangle 7, la boucle de sangle 7 plaque le deuxième anneau 4 contre la face supérieure du premier anneau 3. La sangle tire sur la première extrémité du deuxième anneau 4 pour refermer la fente 6.The first ring 3 can move relative to the second ring 4 in translation and in rotation to modulate the thickness of the slot 6. The second ring 4 has a lower surface which bears on an upper surface of the first ring 3. When when the strap 7 is under tension, the strap loop 7 presses the second ring 4 against the upper face of the first ring 3. The strap pulls on the first end of the second ring 4 to close the slot 6.

La sangle 7 fait le tour du deuxième anneau 4 en passant une fois à travers le trou traversant 5 du deuxième anneau et deux fois à travers le trou traversant 5 du premier anneau 3. La sangle 7 quitte le deuxième anneau 4 sur l'arête extérieure 4b de la face supérieure pour rejoindre le premier anneau 3 sur l'arête intérieure 3a de la face inférieure.The strap 7 goes around the second ring 4, passing once through the through hole 5 of the second ring and twice through the through hole 5 of the first ring 3. The strap 7 leaves the second ring 4 on the outer ridge. 4b of the upper face to join the first ring 3 on the inner edge 3a of the lower face.

En appliquant un effort sur le deuxième anneau 4 de sorte que le deuxième anneau 4 se rapproche du premier anneau 3, l'épaisseur de la fente 6 peut diminuer. L'effort appliqué sur le deuxième anneau 4 correspond à une contrainte en traction entre les deux extrémités.By applying a force to the second ring 4 so that the second ring 4 approaches the first ring 3, the thickness of the slot 6 can decrease. The force applied to the second ring 4 corresponds to a tensile stress between the two ends.

Dans les configurations de l'art antérieur, l'effort appliqué sur la sangle a pour effet de fermer la fente 6 et de bloquer la sangle 7 entre l'arête intérieure 3a et l'arête extérieure 4b. La valeur de l'effort appliqué pour fermer la fente 6 rend d'autant plus difficile l'ouverture de la fente 7 et donc le déréglage du dispositif. Cependant, plus l'effort est important et plus la sangle 7 serre l'utilisateur ce qui peut être inconfortable. La boucle formée par les deux anneaux 3 et 4 définit une position de blocage lors de la mise sous tension de la sangle 7. La mise sous tension de la sangle 7 ferme la fente 6 jusqu'à ce que la sangle 7 empêche le rapprochement de l'arête intérieure 3a avec l'arête extérieure 4b.In the configurations of the prior art, the force applied to the strap has the effect of closing the slot 6 and of locking the strap 7 between the inner ridge 3a and the outer ridge 4b. The value of the force applied to close the slot 6 makes it all the more difficult to open the slot 7 and therefore to adjust the device. However, the greater the effort, the more the strap 7 tightens the user, which can be uncomfortable. The loop formed by the two rings 3 and 4 defines a locking position when tensioning the strap 7. The tensioning of the strap 7 closes the slot 6 until the strap 7 prevents the inner edge 3a from approaching the outer edge 4b.

Pour compliquer le déréglage de la sangle, il est intéressant d'utiliser des arêtes intérieures et supérieures du deuxième anneau qui sont rugueuses et/ou à angle droit pour augmenter le frottement lorsque l'on cherche à faire glisser la sangle 7 par rapport au deuxième anneau 4. Cependant, cette configuration se traduit par une usure accélérée de la surface de sangle 7 et une grande variabilité de la qualité du blocage selon l'état de surface de sangle 7 (humidité, boue, vieillissement...).To complicate the adjustment of the strap, it is advantageous to use interior and upper edges of the second ring which are rough and / or at right angles to increase the friction when one seeks to slide the strap 7 relative to the second ring 4. However, this configuration results in accelerated wear of the strap surface 7 and a great variability in the quality of the locking according to the strap surface condition 7 (humidity, mud, aging, etc.).

Afin de rendre plus difficile le glissement de la sangle 7 par rapport au premier anneau 3 et au deuxième anneau 4, la surface inférieure du premier anneau 3 opposée à la surface supérieure du deuxième anneau 4 possède une zone texturée 8. La zone texturée 8 possède une pluralité d'éléments 9 en saillie qui viennent en contact de la sangle. Les éléments 9 en saillie sont montés fixes sur le premier anneau 3 et plus particulièrement sur la surface inférieure du premier anneau 3. La face inférieure du premier anneau 3 est destinée à venir prendre appui sur l'utilisateur, sur une zone de support d'un harnais ou a minima sur deux brins de la sangle 7 à régler et à bloquer.In order to make it more difficult for the strap 7 to slide relative to the first ring 3 and to the second ring 4, the lower surface of the first ring 3 opposite the upper surface of the second ring 4 has a textured area 8. The textured area 8 has a plurality of projecting elements 9 which come into contact with the strap. The projecting elements 9 are mounted fixedly on the first ring 3 and more particularly on the lower surface of the first ring 3. The lower face of the first ring 3 is intended to come to bear on the user, on a support zone of. a harness or at least on two strands of the strap 7 to be adjusted and locked.

La zone texturée 8 est formée sur la face inférieure du premier anneau 3, c'est-à-dire qu'elle est séparée du deuxième anneau 4 au moyen de la fente 6. Alors que les configurations de l'art antérieur utilisent une surface plane, il est particulièrement avantageux de former la zone texturée 8 qui assure l'obtention d'un frottement plus important entre la sangle 7 et le premier anneau 3. La zone texturée 8 est formée dans la prolongement de la fente 6 selon la direction AA pour venir en contact de la sangle. De manière avantageuse, la zone texturée s'étend sur au moins 80% de la largeur du trou traversant 5 afin de pouvoir coopérer avec une grande partie de la largeur de la sangle 7. Préférentiellement, la zone texturée 8 s'étend sur toute la largeur de l'anneau face au trou traversant selon la direction AA.The textured area 8 is formed on the underside of the first ring 3, i.e. it is separated from the second ring 4 by means of the slot 6. While the prior art configurations use a surface flat, it is particularly advantageous to form the textured zone 8 which ensures obtaining a greater friction between the strap 7 and the first ring 3. The textured zone 8 is formed in the extension of the slot 6 in the direction AA to come into contact with the strap. Advantageously, the textured zone extends over at least 80% of the width of the through-hole 5 in order to be able to cooperate with a large part of the width of the strap 7. Preferably, the textured zone 8 extends over the entire length. width of the ring facing the through hole in direction AA.

Lors de la mise sous tension de la sangle 7 durant la phase de réglage, les deux brins de sangle qui définissent la boucle de sangle qui passe autour du deuxième anneau 4 sont mis sous tension. En conséquence, le brin de sangle en contact direct avec la zone texturée 8 est plaqué contre la zone texturée par l'autre brin de sangle. La contrainte en tension présente dans la sangle 7 plaque les deux brins de sangle 7 contre la face inférieure du premier anneau 3 et donc contre la zone texturée 8. Dans les configurations de l'art antérieur, le maintien du réglage de la sangle 7 s'effectue en utilisant le frottement qui existe entre la sangle et les différentes arêtes, c'est-à-dire sur une surface extrêmement réduite. Selon l'invention, il est possible d'avoir facilement une zone texturée 8 dont la surface est importante et suffisante pour bloquer la sangle 7 en position.When the strap 7 is put under tension during the adjustment phase, the two strap strands which define the strap loop which passes around the second ring 4 are tensioned. As a result, the webbing strand in direct contact with the textured area 8 is pressed against the textured area by the other webbing strand. The tensile stress present in the strap 7 places the two strap strands 7 against the underside of the first ring 3 and therefore against the textured zone 8. In the configurations of the prior art, maintaining the adjustment of the strap 7 s 'performs using the friction that exists between the strap and the various edges, that is to say on an extremely small surface. According to the invention, it is possible to easily have a textured zone 8, the surface of which is large and sufficient to block the strap 7 in position.

La zone texturée 8 peut être formée de différentes manières pour augmenter le frottement entre le premier anneau 3 et la sangle 7. La zone texturée 8 peut être formée par des motifs en vague, en barres perpendiculaire à la direction AA, en carrés, triangles, rectangles, étoiles et de formes quelconques qui incitent la sangle 7 à se déformer et donc augmenter le frottement. De préférence, l'épaisseur de la texturation est au moins égale à 0,5mm et de préférence entre 0,5mm et 2mm.The textured area 8 can be formed in different ways to increase the friction between the first ring 3 and the strap 7. The textured area 8 can be formed by wave patterns, bars perpendicular to the direction AA, squares, triangles, rectangles, stars and any shapes that encourage the strap 7 to deform and therefore increase the friction. Preferably, the thickness of the texturing is at least equal to 0.5mm and preferably between 0.5mm and 2mm.

La zone texturée 8 comporte avantageusement une pluralité de picots 9 qui sont configurés pour s'enfoncer dans la sangle 7. De manière préférentielle, les picots 9 possèdent une hauteur qui est inférieure ou égale à l'épaisseur de la sangle 7. Il est également possible d'avoir des picots 9 dont la hauteur est supérieure à l'épaisseur de la sangle 6 et avantageusement inférieure à deux fois l'épaisseur de la sangle 6. Les picots 9 peuvent avoir une orientation quelconque. De manière avantageuse, les éléments en saillie 9 sont disposés à une première distance de l'arête intérieure 3a. La première distance est non nulle et inférieure à deux fois l'épaisseur du premier anneau 3.The textured zone 8 advantageously comprises a plurality of pins 9 which are configured to sink into the strap 7. Preferably, the pins 9 have a height which is less than or equal to the thickness of the strap 7. It is also possible to have pins 9 whose height is greater than the thickness of the strap 6 and advantageously less than twice the thickness of the strap 6. The pins 9 can have any orientation. Advantageously, the projecting elements 9 are arranged at a first distance from the inner edge 3a. The first distance is non-zero and less than twice the thickness of the first ring 3.

La sangle 7 est dépourvue de trous traversants qui traversent toute l'épaisseur de la sangle 7.The strap 7 has no through holes which pass through the entire thickness of the strap 7.

Dans un mode de réalisation particulier, la zone texturée 8 est définie dans la masse du premier anneau 3. Par exemple, les picots 9 sont formés en saillie de la surface inférieure du premier anneau 3 dans le même matériau que le corps du premier anneau 3. Un tel mode de réalisation est illustré aux figures 2, 3 et 6. Les picots 9 peuvent être des picots métalliques disposés en saillie du corps métallique du premier anneau 3. La figure 6 représente une vue agrandie de la figure 2 illustrant l'insertion d'un picot 9 dans l'épaisseur d'un brin de sangle 7 sans atteindre le second brin de sangle 7.In a particular embodiment, the textured zone 8 is defined in the mass of the first ring 3. For example, the pins 9 are formed projecting from the lower surface of the first ring 3 in the same material as the body of the first ring 3. Such an embodiment is illustrated in figures 2 , 3 and 6 . The pins 9 can be metal pins projecting from the metal body of the first ring 3. The figure 6 represents an enlarged view of the figure 2 illustrating the insertion of a pin 9 in the thickness of a strap strand 7 without reaching the second strap strand 7.

Dans un autre mode de réalisation, la zone texturée 8 est formée par surmoulage d'un matériau plastique sur le corps du premier anneau 3. La zone texturée 8 est montée inamovible du corps du premier anneau 3. Un tel mode de réalisation est illustré à la figure 5. Dans un cas de figure, la partie surmoulée recouvre intégralement le corps du premier anneau 3. Dans un autre cas de figure, la partie surmoulée recouvre partiellement le corps du premier anneau 3, par exemple la portion du corps qui se trouve dans le prolongement de la sangle 7 à partir de la première arête 3a qui définit la fente 6 selon la direction AA.In another embodiment, the textured area 8 is formed by overmolding a plastic material on the body of the first ring 3. The textured area 8 is mounted non-removable from the body of the first ring 3. Such an embodiment is illustrated at the figure 5 . In one case, the molded part completely covers the body of the first ring 3. In another case, the molded part partially covers the body of the first ring 3, for example the portion of the body which is in the extension of the strap 7 from the first edge 3a which defines the slot 6 in the direction AA.

Dans un autre mode de réalisation, la zone texturée 8 est formée par une pièce amovible 10 montée sur le corps du premier anneau 3. Un tel mode de réalisation est illustré à la figure 4. La pièce amovible 10 est avantageusement une pièce en matière plastique. Il est alors possible d'installer la pièce plastique qui possède la zone texturée 8 sur un premier anneau qui en était initialement dépourvu. La pièce amovible forme un support qui recouvre au moins partiellement la surface inférieure du premier anneau 3 et forme un crochet recouvrant l'arête intérieure et une partie de la surface supérieure. Cette configuration permet de maintenir le support en position au moyen de la contrainte appliquée par la sangle sur le support 10.In another embodiment, the textured zone 8 is formed by a removable part 10 mounted on the body of the first ring 3. Such an embodiment is illustrated in FIG. figure 4 . The removable part 10 is advantageously a plastic part. It is then possible to install the plastic part which has the textured zone 8 on a first ring which was initially devoid of it. The removable part forms a support which at least partially covers the lower surface of the first ring 3 and forms a hook covering the inner ridge and part of the upper surface. This configuration makes it possible to keep the support in position by means of the stress applied by the strap on the support 10.

Il est particulièrement avantageux de former une zone texturée 8 qui est décalée de l'arête intérieure 3a. Lorsque la zone texturée 8 est formée par des picots 9, il est avantageux d'avoir une arête intérieure 3a plane et de former des rangées de picots 9 disposés à distance de l'arête intérieure 3a. Par exemple, les motifs de la zone texturés qui sont les plus proches de l'arête 3a sont au moins à 1mm de l'arête.It is particularly advantageous to form a textured area 8 which is offset from the inner edge 3a. When the textured zone 8 is formed by pins 9, it is advantageous to have a flat interior edge 3a and to form rows of pins 9 arranged at a distance from the interior edge 3a. For example, the patterns of the textured zone which are closest to the edge 3a are at least 1mm from the edge.

Il est également avantageux de prévoir que la zone texturée 8 possède plusieurs rangées de motifs, par exemple des picots et que préférentiellement la première rangée de picots 9 possède une hauteur moins importante que la deuxième rangée de picots 9. La première rangée de picots 9 sépare l'arête intérieure 3a et la deuxième rangée de picots 9. Il est également avantageux de prévoir que la deuxième rangée de picots 9 soit décalée par rapport à la première rangée de picots 9 selon une direction perpendiculaire à la direction longitudinale de la sangle 7 qui correspond à la direction qui relie l'arête intérieure 3a, la première rangée de picots 9 et la deuxième rangée de picots 9. En utilisant une première rangée de motifs/picots 9 dont la hauteur est réduite, il est possible de régler plus facilement la sangle 7 en la faisant coulisser sans être gênée par les premiers motifs/picots 9.It is also advantageous to provide that the textured zone 8 has several rows of patterns, for example pins and that preferably the first row of pins 9 has a lower height than the second row of pins 9. The first row of pins 9 separates the inner ridge 3a and the second row of pins 9. It is also advantageous to provide that the second row of pins 9 is offset with respect to the first row of pins 9 in a direction perpendicular to the longitudinal direction of the strap 7 which corresponds to the direction which connects the inner edge 3a, the first row of pins 9 and the second row of pins 9. By using a first row of patterns / pins 9 whose height is reduced, it is possible to adjust the height more easily. strap 7 by sliding it without being hampered by the first patterns / pins 9.

Comme illustré à la figure 2, lorsque la sangle 7 est mise sous contrainte, la boucle qui passe autour du deuxième anneau 4 plaque le deuxième anneau 4 contre la surface supérieure du premier anneau 3 et plaque la sangle 7 contre la surface inférieure du premier anneau 3 et contre la zone texturée 8. Le frottement induit par la zone texturée réduit ou empêche le glissement de la sangle 7 par rapport au premier anneau 3 et donc le glissement de la sangle 7 à l'intérieur de la boucle. Il n'est plus nécessaire d'avoir le coincement de la sangle 7 entre l'arête intérieure 3a et l'arête extérieure 4b ou d'avoir une contrainte important.As shown in figure 2 , when the strap 7 is put under stress, the loop which passes around the second ring 4 presses the second ring 4 against the upper surface of the first ring 3 and presses the strap 7 against the lower surface of the first ring 3 and against the textured area 8. The friction induced by the textured zone reduces or prevents the slipping of the strap 7 relative to the first ring 3 and therefore the slipping of the strap 7 inside the buckle. It is no longer necessary to have the strap 7 jamming between the inner edge 3a and the outer edge 4b or to have a significant constraint.

Afin d'augmenter la pression entre la surface inférieure du premier anneau 3 et la sangle 7, il est avantageux de former un premier anneau 3 incurvé et concave. Dans le mode de réalisation illustré, le corps du premier anneau 3 s'étend selon une première direction A qui passe, dans l'ordre, par la première extrémité, la zone texturée 8, la première arête 3a, l'orifice traversant 5 et la deuxième extrémité du corps. La deuxième extrémité du corps est fixée au harnais 1 et/ou la sangle 7. La courbure de la première extrémité incurvée impose à la sangle de se déformer ce qui assure le contact entre la sangle et la zone texturée.In order to increase the pressure between the lower surface of the first ring 3 and the strap 7, it is advantageous to form a first curved and concave ring 3. In the illustrated embodiment, the body of the first ring 3 extends in a first direction A which passes, in order, through the first end, the textured zone 8, the first edge 3a, the through orifice 5 and the second end of the body. The second end of the body is fixed to the harness 1 and / or the strap 7. The curvature of the curved first end forces the strap to deform which ensures contact between the strap and the textured zone.

Dans l'exemple de réalisation illustré à la figure 2, la sangle 7 forme une boucle fermée qui passe au travers des deux orifices traversants 5 afin de permettre un déplacement en translation du premier anneau 3 par rapport au deuxième anneau 4 ainsi qu'un mouvement de rotation du deuxième anneau 4 par rapport au premier anneau 3. La boucle fermée entoure la seconde extrémité des deux anneaux 3 et 4.In the exemplary embodiment illustrated in figure 2 , the strap 7 forms a closed loop which passes through the two through holes 5 in order to allow a translational movement of the first ring 3 relative to the second ring 4 as well as a rotational movement of the second ring 4 relative to the first ring 3. The closed loop surrounds the second end of the two rings 3 and 4.

La contrainte appliquée sur la sangle 7 bloque la sangle 7 contre la zone texturée 8 et peut fermer la fente 6. La boucle est dans la position de blocage.The stress applied to the strap 7 locks the strap 7 against the textured area 8 and can close the slit 6. The buckle is in the locked position.

Comme illustré à la figure 3, en réalisant la rotation des deux anneaux 3/4 par rapport au point de fixation du harnais d'encordement 1 défini par la boucle fermée 11, la sangle 7 qui est en appui sur l'arête extérieure quitte la zone texturée 8 avant de quitter l'arête intérieure 3a. Une fois la rotation réalisée, le contact entre la sangle 7 et la zone texturée 8 s'arrête et la boucle de sangle glisse autour du deuxième anneau 4.As shown in figure 3 , by rotating the two rings 3/4 with respect to the attachment point of the tying harness 1 defined by the closed loop 11, the strap 7 which is resting on the outer edge leaves the textured zone 8 before leaving the inner ridge 3a. Once the rotation is complete, the contact between the strap 7 and the textured area 8 stops and the strap loop slides around the second ring 4.

Il est particulièrement avantageux que le deuxième anneau 4 possède une surface supérieure lisse ainsi que des arêtes intérieure et extérieure de la surface supérieure lisses et arrondies pour faciliter le glissement de la sangle sur le deuxième anneau 4.It is particularly advantageous that the second ring 4 has a smooth upper surface as well as inner and outer ridges of the upper surface which are smooth and rounded to facilitate the sliding of the strap over the second ring 4.

En introduisant une zone texturée 8 qui assure le blocage de la sangle 7, il est avantageux de former des arêtes intérieures lisses et arrondies pour éviter d'user prématurément la surface de la sangle 7. L'arête intérieure supérieure et/ou inférieure peuvent présenter un rayon de courbure qui est au moins égale à 1/6 de l'épaisseur du premier anneau 3. Une telle configuration rend difficile le blocage de la sangle 7 au moyen de la fente 6 en l'absence d'une zone texturée 8.By introducing a textured zone 8 which secures the locking of the strap 7, it is advantageous to form smooth and rounded interior ridges to avoid prematurely wearing out the surface of the strap 7. The upper and / or lower interior ridge may present a radius of curvature which is at least equal to 1/6 of the thickness of the first ring 3. Such a configuration makes it difficult to block the strap 7 by means of the slot 6 in the absence of a textured zone 8.

Lorsque le premier anneau 3 est incurvé, il possède au moins une zone d'inflexion qui sépare au moins une première portion et une deuxième portion du corps. La première portion de l'anneau, de préférence formée par le corps possède la zone texturée 8 ou est destinée à recevoir la zone texturée 8. La première portion possède une première surface inférieure qui définit la zone texturée 8. La deuxième portion est fixée au harnais 1 ou l'autre extrémité de la sangle 7. Le deuxième anneau 4 appuie sur la deuxième portion.When the first ring 3 is curved, it has at least one zone of inflection which separates at least a first portion and a second portion of the body. The first portion of the ring, preferably formed by the body has the textured area 8 or is intended to receive the textured area 8. The first portion has a first lower surface which defines the textured area 8. The second portion is attached to the harness 1 or the other end of the strap 7. The second ring 4 presses on the second portion.

Il est avantageux que le premier anneau 3 définisse une forme en V ou en U et plus précisément un V ou un U renversé avec la zone d'inflexion qui forme le sommet du V ou du U renversé. La base du premier anneau 3 vient en appui contre une zone de support du harnais 1 ou contre l'utilisateur de sorte que la sangle 7 sépare le premier anneau 3 et la zone de support ou l'utilisateur.It is advantageous for the first ring 3 to define a V or U shape and more precisely an inverted V or U with the zone of inflection which forms the apex of the inverted V or U. The base of the first ring 3 bears against a support zone of the harness 1 or against the user so that the strap 7 separates the first ring 3 and the support zone or the user.

Il est avantageux que la première portion définisse un renfoncement 12. Le renfoncement 12 est défini dans la surface inférieure pour faciliter l'insertion d'un doigt qui permet de faire tourner les deux anneaux 3/4, par exemple faire tourner les deux anneaux 3/4 autour d'un axe de rotation formé par une arête extérieure 3b du premier anneau 3 à la deuxième extrémité. Lors de la rotation, l'effort appliqué sur la sangle augmente jusqu'à ce que le contact entre la sangle 7 et la zone texturée se réduise ou disparaisse. Une fois la valeur seuil de rotation atteinte, la sangle peut glisser par rapport aux anneaux.It is advantageous that the first portion defines a recess 12. The recess 12 is defined in the lower surface to facilitate the insertion of a finger which makes it possible to rotate the two rings 3/4, for example to rotate the two rings 3. / 4 around an axis of rotation formed by an outer edge 3b of the first ring 3 at the second end. During the rotation, the force applied to the strap increases until the contact between the strap 7 and the textured zone is reduced or disappeared. Once the threshold value of rotation has been reached, the strap can slip relative to the rings.

Il est avantageux que le premier anneau 3 soit de dimension inférieure au deuxième anneau 4 et préférentiellement que la longueur de la deuxième portion selon la direction A soit inférieure à la longueur du deuxième anneau 4 de sorte que le deuxième anneau 4 soit uniquement en appui sur la deuxième portion.It is advantageous that the first ring 3 is of smaller dimension than the second ring 4 and preferably that the length of the second portion in direction A is less than the length of the second ring 4 so that the second ring 4 is only resting on the second portion.

La sangle 7 est dépourvue de trous traversants prédéfinis et les picots 9 sont montés immobiles sur le premier anneau 3. La configuration est différente de ce qui est utilisé dans une boucle de ceinture où la longueur effective de la ceinture est prédéfinie par les trous. La configuration selon l'invention permet un réglage continu de la longueur effective de la sangle 7.The strap 7 is devoid of predefined through holes and the pins 9 are mounted stationary on the first ring 3. The configuration is different from what is used in a belt buckle where the effective length of the belt is predefined by the holes. The configuration according to the invention allows continuous adjustment of the effective length of the strap 7.
