Abstract

The buckle has the form of a frame with small bars (2, 3) at one end for fastening an end of the strap (4) and, at its opposite end, a small bar (5) which forms a stationary jaw. An element (8) forming a movable jaw has a part (9) of semicylindrical form and a part (10) with a triangular cross section. The element (8) pivots around an eccentric spindle (13) arranged right next to the upper edge of the part (9), and the edge (11) of the part (10) acts as a movable jaw to grip the strap (4) against the stationary jaw (5). The strap (4) surrounds the semicylindrical part (9) before being engaged between the stationary and movable jaws. <IMAGE>

Description

L'invention concerne une boucle à tension directe pour constituer une ceinture avec une sangle en textile végétal ou synthétique.The invention relates to a direct tension buckle to constitute a belt with a strap of vegetable or synthetic textile.

Il existe de nombreux modèles de boucles de ce type. Parmi ceux-ci toutes les boucles à dispositif autoserreur à barrettes coulissant dans un cadre conviennent pour retenir de faibles charges, mais elles laissent glisser la sangle si la charge est trop importante ou s'il y a des vibrations. Il existe également d'autres modèles plus élaborés et actuellement très répandus, les boucles étant alors constituées par un carter en forme de cadre qui comprend une barrette arrière pour fixer une extrémité de la sangle par couture et une barrette avant, constituant une mâchoire statique crantée, sur laquelle vient coulisser la sangle pour assurer sa tension et son arrêt. Les deux parois latérales du cadre sont verti- cales et présentent un trou de part en part, pour l'introduction d'un axe destiné à recevoir en montage articulé une mâchoire autoserreuse par excentration et crantée, généralement en pointe de diamant, indispensable pour assurer son accrochage sur la sangle et ainsi permettre sa retenue par le mouvement excentré de la mâchoire. Un ressort relativement fort maintient la mâchoire excentrée en pression permanente sur la mâchoire statique, ce qui abîme la sangle lors du coulissement de celle-ci pour sa tension.There are many models of such buckles. Among these all loops with a self-locking device with bars sliding in a frame are suitable for retaining low loads, but they let the strap slip if the load is too heavy or if there is vibration. There are also other more elaborate and currently widespread models, the buckles then being constituted by a frame-shaped casing which includes a rear bar for fixing one end of the strap by sewing and a front bar, constituting a notched static jaw. , on which the strap slides to ensure its tension and stop. The two side walls of the frame are vertical - and have a hole right through, for the introduction of an axis intended to receive in articulated assembly a self-tightening jaw by eccentricity and notched, generally in diamond point, essential to ensure its attachment to the strap and thus allow its retention by the eccentric movement of the jaw. A relatively strong spring keeps the eccentric jaw in permanent pressure on the static jaw, which damages the strap when it slides for its tension.

Un levier compris dans la mâchoire autoserreuse est prévu pour être actionné manuellement. Ce levier permet d'annuler la pression du ressort afin d'écarter les mâchoires pour introduire la sangle dans la boucle et la retirer. Du fait des variations d'épaisseur des sangles pouvant être utilisées et de la forme du '.serrage, ces boucles ont une efficacité toute relative et n'offrent aucune sécurité.A lever included in the self-tightening jaw is provided to be actuated manually. This lever allows you to cancel the spring pressure in order to spread the jaws to introduce the strap into the buckle and remove it. Due to the variations in thickness of the straps that can be used and the shape of the tightening, these loops have a relative efficiency and offer no security.

.La présente invention a pour objet une boucle d'une présentation sur certains points sensiblement identique à certains types de l'exemple ci-avant décrit. En effet, cette nouvelle boucle est également constituée par un carter en forme de cadre comprenant des parois latérales positionnées verticalement. Ce cadre comprend une ou deux barrettes arrière pour fixer une extrémité de la sangle par couture ou en autoserrage suivant un passage déterminé de la sangle sur les deux barrettes. Une autre barrette, située à l'avant du cadre, constitue une mâchoire statique semblable au modèle de boucle ci-avant décrit. La différence technique, objet de l'invention, se situe au niveau de la conception et du fonctionnement de la mâchoire mobile, autoserreuse, qui engendre une action logique dans la coopération des deux mâchoires et, par conséquent, un effet de serrage absolu en efficacité et dont l'intensité est toujours fonction de la charge à retenir..The present invention relates to a loop of a presentation on certain points substantially identical to certain types of the example described above. In fact, this new loop also consists of a frame-shaped casing comprising side walls positioned vertically. This frame includes one or two rear bars for fixing one end of the strap by sewing or self-tightening according to a determined passage of the strap on the two bars. Another bar, located at the front of the frame, constitutes a static jaw similar to the buckle model described above. The technical difference, object of the invention, lies in the design and operation of the movable, self-tightening jaw, which generates a logical action in the cooperation of the two jaws and, therefore, an absolute clamping effect in efficiency. and the intensity of which is always a function of the charge to be retained.

Ces caractéristiques techniques sont les suivantes :These technical characteristics are as follows:

Dans cette nouvelle boucle, la mâchoire mobile autoserreuse est constituée par une pièce au pourtour en forme fractionnée. Une fraction est de forme hémicylindrique, et une autre fraction forme un relief relativement triangulaire dont une des faces constitue une mâchoire mobile.In this new loop, the self-tightening movable jaw is made up of a part with a circumference in split form. A fraction is semi-cylindrical, and another fraction forms a relatively triangular relief, one of the faces of which constitutes a movable jaw.

Pour son montage articulé dans les parois latérales du cadre, la fraction hémicylindrique est traversée longitudinalement par un trou excentré situé le plus près possible du bord extérieur et judicieusement positionné par rapport à la fraction formant mâchoire. Cette conception schématise un triangle qui se résume ainsi :

  • Un point d'appui qui est l'articulation excentrée, un levier démultiplié qui est constitué par la fraction formant mâchoire et un levier multiplicateur constitué par la fraction de la partie hémicylindrique la plus éloignée de l'axe d'articulation.
For its articulated mounting in the side walls of the frame, the semi-cylindrical fraction is traversed longitudinally by an eccentric hole located as close as possible to the outer edge and judiciously positioned with respect to the jaw-forming fraction. This design schematizes a triangle which can be summarized as follows:
  • A fulcrum which is the eccentric joint, a multiplied lever which is constituted by the fraction forming jaw and a multiplier lever constituted by the fraction of the semi-cylindrical part furthest from the axis of articulation.

Le fonctionnement est simple à comprendre. Alors que dans les systèmes de boucles à mâchoire excentrée la sangle prend son appui directement sur la mâchoire statique, selon la présente invention la sangle enveloppe et prend son appui sur la mâchoire mobile suivant un sens déterminé pour venir ensuite s'engager et coulisser parallèlement entre les deux mâchoires ce qui assure un coulissement très libre de la sangle et permet ainsi à l'utilisateur d'obtenir un maximum de tension.The operation is simple to understand. While in eccentric jaw buckle systems the strap takes its support directly on the static jaw, according to the present invention the strap wraps and takes its support on the movable jaw in a determined direction to then engage and slide parallel between the two jaws which ensures a very free sliding of the strap and thus allows the user to obtain maximum tension.

L'efficacité du serrage de la sangle entre les deux mâchoires pour assurer son arrêt en blocage est due à l'appui et à l'effet de friction de la sangle sur la partie hémicylindrique de la mâchoire mobile . Cette friction et cet appui engendrent une multiplication de forces dans l'action du levier grâce à l'excentration maximale de la fraction hémicylindrique. L'opération de tension de la sangle provoque un effet inverse d'entrainement de la mâchoire mobile qui libère totalement le passage de la sangle entre les mâchoires sans pour cela l'entraîner totalement du fait de son articulation excentrée.The effectiveness of the tightening of the strap between the two jaws to ensure its stop in blocking is due to the support and the friction effect of the strap on the semi-cylindrical part of the movable jaw. This friction and this support generate a multiplication of forces in the action of the lever thanks to the maximum eccentricity of the semi-cylindrical fraction. The tensioning operation of the strap causes an opposite effect of training of the movable jaw which completely frees the passage of the strap between the jaws without for this completely entraining it because of its eccentric articulation.

Le déverrouillage de la sangle est assuré par l'axe d'articulation qui est rendu solidaire de la mâchoire mobile autoserreuse et qui forme à l'extérieur du cadre un levier destiné à être actionné à la main. Un ressort judicieusement positionné est prévu pour maintenir les mâchoires en contact permanent.The strap is unlocked by the hinge pin which is made integral with the self-tightening movable jaw and which forms a lever outside the frame intended to be actuated by hand. A judiciously positioned spring is provided to keep the jaws in permanent contact.

Cette nouvelle conception de boucle à tension directe permet de réaliser des mâchoires à surfaces de serrage relativement importantes ce qui apporte une protection considérable de la sangle, assurant sa longévité.This new design of direct tension buckle makes it possible to produce jaws with relatively large clamping surfaces, which provides considerable protection for the strap, ensuring its longevity.

Pour bien faire comprendre la boucle selon l'invention, on en décrira ci-après, à titre d'exemple sans caractère limitatif, une forme d'exécution préférée en référence au dessin schématique annexé dans lequel :

  • la figure 1 est une vue en coupe longitudinale d'une boucle selon la présente invention, prise selon la ligne 1-1 de la figure 2 ;
  • la figure 2 est une vue en plan de la boucle ;
  • la figure 3 montre en coupe longitudinale le montage d'une mâchoire autoserreuse à chaque extrémité d'une boucle ;
  • la figure 4 est une coupe transversale prise selon la ligne IV-IV de la figure 3 ; et
  • la figure 5 est une coupe transversale prise selon la ligne V-V de la figure 3.
To clearly understand the loop according to the invention, there will be described below, by way of example without limitation, a preferred embodiment with reference to the attached schematic drawing in which:
  • Figure 1 is a longitudinal sectional view of a loop according to the present invention, taken along line 1-1 of Figure 2;
  • Figure 2 is a plan view of the loop;
  • Figure 3 shows in longitudinal section the mounting of a self-tightening jaw at each end of a loop;
  • Figure 4 is a cross section taken along the line IV-IV of Figure 3; and
  • FIG. 5 is a cross section taken along the line VV in FIG. 3.

La boucle selon l'invention, représentée aux figures 1 et 2, se compose d'un carter 1 en forme de cadre, comprenant deux barrettes 2, 3 situées à l'arrière du cadre pour permettre la fixation en autoserrage et suivant un passage déterminé de la sangle 4 sur les barrettes 2 et 3, en permettant un réglage en longueur de la sangle. En variante, la sangle pourrait être fixée sur les barrettes 2, 3 par couture.The loop according to the invention, represented in FIGS. 1 and 2, consists of a casing 1 in the form of a frame, comprising two bars 2, 3 situated at the rear of the frame to allow fixing in self-tightening and according to a determined passage. of the strap 4 on the bars 2 and 3, allowing an adjustment in length of the strap. Alternatively, the strap could be attached to the bars 2, 3 by sewing.

Une barrette 5, située sur l'avant du cadre, constitue une mâchoire statique. Les parois latérales identiques 6, 6' du cadre 1, positionnées verticalement, présentant chacune un trou 7, 7' qui est destiné à recevoir en montage articulé un élément 8 formant mâchoire mobile autoserreuse au pourtour de forme fractionnée. Une fraction 9 est de forme hémicylindrique et une autre fraction 10 forme un relief pratiquement triangulaire dont l'une des faces constitue une mâchoire mobile 11. La fraction hémicylindrique 9 est traversée longitudinalement par un alésage 12, disposé près de son bord supérieur, qui reçoit un axe 13 venant s'articuler dans les trous 7, 7' des parois verticales 6, 6'. Cette conception schématise un triangle qui a pour point d'appui l'axe d'articulation 13 et dont la partie hémicylindrique la plus éloignée de l'axe 13 constitue un levier qui assure, de façon automatique et multipliée, le serrage de la mâchoire 11 sur la mâchoire 5 et, par conséquent, un serrage d'une efficacité absolue de la sangle 4 entre ces mâchoires.A bar 5, located on the front of the frame, constitutes a static jaw. The identical side walls 6, 6 'of the frame 1, positioned vertically, each having a hole 7, 7' which is intended to receive in articulated assembly an element 8 forming a self-tightening mobile jaw at the periphery of fractional shape. A fraction 9 is of semi-cylindrical shape and another fraction 10 forms a practically triangular relief of which one of the faces constitutes a movable jaw 11. The semi-cylindrical fraction 9 is traversed longitudinally by a bore 12, disposed near its upper edge, which receives an axis 13 coming to articulate in the holes 7, 7 'of the vertical walls 6, 6'. This design shows schematically a triangle which has as its fulcrum the articulation axis 13 and whose semi-cylindrical part furthest from the axis 13 constitutes a lever which ensures, automatically and multiplied, the clamping of the jaw 11 on the jaw 5 and, consequently, an absolutely effective tightening of the strap 4 between these jaws.

A l'examen de la figure 1, on comprend immédiatement l'efficacité fonctionnelle de la mâchoire autoserreuse 11. Comme on le voit à la figure 1, la sangle 4 se trouve sous tension suivant la flèche A, en étant montée serrée sur des barres 19 et 19'. La sangle 4 est bloquée dans la boucle après son passage en appui sur la fraction hémicylindrique 9 de l'élément 8 dont la partie 11 formant mâchoire autoserreuse effectue son serrage sur la sangle 4 contre la mâchoire 5. On constate clairement l'effet de friction exercé par la sangle 4 sur le levier 8 qui engendre une multiplication du couple exercé sur le levier 8 suivant la flèche B de la figure 1 et provoque ainsi instantanément et automatiquement le serrage de la sangle 4 entre les mâchoires 5 et 11 avec une intensité qui est toujours proportionnelle à la charge appliquée à la sangle 4.On examining FIG. 1, one immediately understands the functional efficiency of the self-tightening jaw 11. As can be seen in FIG. 1, the strap 4 is under tension according to arrow A, being mounted tight on bars 19 and 19 '. Strap 4 is locked in the buckle after its passage in bearing on the semi-cylindrical fraction 9 of the element 8 whose part 11 forming a self-tightening jaw tightens on the strap 4 against the jaw 5. We can clearly see the friction effect exerted by the strap 4 on the lever 8 which generates a multiplication of the torque exerted on the lever 8 according to the arrow B in FIG. 1 and thus instantly and automatically causes the tightening of the strap 4 between the jaws 5 and 11 with an intensity which is always proportional to the load applied to strap 4.

Le déverrouillage de la mâchoire 11 est assuré par un levier de commande 14 qui est réalisé en prolongement de l'axe 13 et est destiné, à cet effet, à être basculé dans la direction de la flèche D de la figure 1.The jaw 11 is unlocked by a control lever 14 which is produced as an extension of the axis 13 and is intended, for this purpose, to be tilted in the direction of the arrow D in FIG. 1.

Pour la tension de la sangle 4, l'utilisateur effectue une traction sur l'extrémité libre de celle-ci dans la direction de la flèche C de la figure 1, ce qui a pour effet de faire pivoter l'élément 8 dans le sens opposé à la flèche B en libérant totalement le passage de la sangle entre les mâchoires et en évitant ainsi d'une part l'effort del'utilisateur et, d'autre part, l'usure de la sangle.For the tension of the strap 4, the user pulls on the free end thereof in the direction of the arrow C in FIG. 1, which has the effect of rotating the element 8 in the direction opposite the arrow B by completely freeing the passage of the strap between the jaws and thus avoiding on the one hand the effort of the user and, on the other hand, the wear of the strap.

L'axe de rotation excentré 13 de l'élément 8 présente en son centre un plat 15 (voir figure 1) qui, par sertissage de l'alésage 12 de l'élément 8, assure le verrouillage de l'axe 13 sur l'élément 8. Le verrouillage de l'axe 13 pourrait aussi être assuré en prévoyant un profil approprié de cet axe (par exemple à six pans, carré, etc .0. ) .The eccentric axis of rotation 13 of the element 8 has in its center a flat 15 (see Figure 1) which, by crimping the bore 12 of the element 8, ensures the locking of the axis 13 on the element 8. The locking of the axis 13 could also be ensured by providing an appropriate profile for this axis (for example with hexagon, square, etc. .0.).

A la figure 3, on a représenté, en variante, une boucle 16 dont chacune des deux extrémités présente un élément excentrique formant mâchoire autoserreuse 17, 18. Une telle disposition présente l'avantage de permettre un réglage de la position de la boucle, afin que celle-ci soit toujours facilement accessible.In Figure 3, there is shown, alternatively, a loop 16 each of whose two ends has an eccentric element forming a self-tightening jaw 17, 18. Such an arrangement has the advantage of allowing adjustment of the position of the loop, so that it is always easily accessible.

L'élément 17 présente une mâchoire plate 20 articulée autour d'un axe 21. Ce montage permet, lors du serrage de la sangle 4, d'obtenir un excellent parallélisme entre la mâchoire fixe 22 et la mâchoire mobile 20. Ceci accroit la surface de serrage de la sangle et permet d'obtenir un serrage très efficace sans risque de détérioration de la sangle.The element 17 has a flat jaw 20 articulated around an axis 21. This assembly makes it possible, when tightening the strap 4, to obtain excellent parallelism between the fixed jaw 22 and the movable jaw 20. This increases the surface tightening strap and provides a very effective tightening without risk of deterioration of the strap.

Associé à l'élément excentrique 18 de la figure 3, on a représenté un ressort de torsion 23 enroulé autour de l'axe de rotation excentré 24 et dont une extrémité s'appuie dans une encoche 25 de la paroi latérale de la boucle 16. Ce ressort 23 a pour rôle de maintenir les mâchoires en contact permanent.Associated with the eccentric element 18 of FIG. 3, there is shown a torsion spring 23 wound around the eccentric axis of rotation 24 and one end of which rests in a notch 25 in the side wall of the loop 16. The role of this spring 23 is to keep the jaws in permanent contact.

On comprendra que la description ci-dessus n'a été donnée qu'à simple titre d'exemple, et que des adjonctions ou des modifications constructives pourraient y être apportées sans sortir du cadre de la présente invention.It will be understood that the above description has been given only by way of example, and that additions or constructive modifications could be made without departing from the scope of the present invention.
