This rack is preferably movable and connected to two cables (23, 24) for clamping the foot, the upper (4) being closed and clamped by a cable (17) attached to the tensioning lever (9) and acting on the rack in a direction opposite to that of the other cables (23, 24).

Description

La présente invention a pour objet une chaussure de ski à coque du type à entrée arrière, comprenant un bas de coque rigide et une tige en deux partie constituée d'une partie antérieure et d'une partie postérieure articulée sur le bas de coque et sur laquelle est monté un dispositif de tension travaillant dans un plan vertical et agissant sur au moins un câble de traction d'un moyen de fermeture et/ou de serrage au moyen d'un levier-tendeur articulé sur un support.The present invention relates to a shell ski boot of the rear entry type, comprising a rigid shell bottom and a two-part upper consisting of a front part and a rear part articulated on the bottom of the shell and on which is mounted a tensioning device working in a vertical plane and acting on at least one traction cable of a closing and / or tightening means by means of a tensioning lever articulated on a support.

Du brevet LEDERER EP 0113908 on connaît une chaussure à entrée arrière munie d'un levier-tendeur articulé sur un support dont la position est réglable et agissant sur un câble unique exerçant un serrage diagonal du pied. Le levier-tendeur est rabattable vers le haut. Du même document on connaît également un levier-tendeur monté sur un support fixe et agissant sur deux câbles serrant simultanément la cheville et le cou-de-pied. Le levier est rabattable vers le bas.LEDERER patent EP 0113908 discloses a shoe with rear entry provided with a tensioning lever articulated on a support whose position is adjustable and acting on a single cable exerting a diagonal tightening of the foot. The tensioning lever can be folded up. From the same document, there is also known a tensioning lever mounted on a fixed support and acting on two cables simultaneously tightening the ankle and the instep. The lever can be folded down.

Une chaussure comportant à l'arrière un levier-tendeur agissant sur un câble fermant la tige de la chaussure dans sa partie supérieure est également connue du brevet FR 2556189 (US 4596080).A shoe comprising at the rear a tensioning lever acting on a cable closing the upper of the shoe in its upper part is also known from patent FR 2556189 (US 4,596,080).

Du brevet US 4539763 on connaît également une chaussure munie à l'arrière d'un levier rabattable vers le haut et tirant sur un câble serrant le cou-de-pied diagonalement.Patent US 4539763 also discloses a shoe provided at the rear with a lever that can be folded up and pulling on a cable tightening the instep diagonally.

Dans les chaussures connues, la longueur de câble relâchée lors de l'ouverture du levier-tendeur est déterminée par la distance entre le point d'attache du câble au levier-tendeur à l'axe d'articulation de ce levier-tendeur. Si cette longueur de câble est généralement suffisante pour serrer et déserrer le pied, par contre elle est insuffisante pour permettre une large ouverture de la chaussure, lorsque le câble est chargé de fermer la tige de la chaussure et de serrer celle-ci. Pour augmenter cette longueur de câble, il est nécessaire de déplacer le point d'attache du câble vers l'extrémité du levier-tendeur, ce qui a pour effet de supprimer l'effet de levier de celui-ci, sans compter la chute de tension importante du câble après le passage du levier-tendeur par un point de tension maximale, lors de sa fermeture. Cette tension maximale peut être particulièrement difficile à vaincre lors de l'ouverture du levier-tendeur.In known shoes, the length of cable released when the tensioning lever is opened is determined by the distance between the point of attachment of the cable to the tensioner lever at the hinge pin of this tensioner lever. If this cable length is generally sufficient to tighten and loosen the foot, on the other hand it is insufficient to allow a wide opening of the shoe, when the cable is responsible for closing the upper of the shoe and tightening it. To increase this cable length, it is necessary to move the cable attachment point towards the end of the tensioning lever, which has the effect of eliminating the lever effect of the latter, without counting the drop in significant tension in the cable after the tensioner lever has passed through a point of maximum tension when it is closed. This maximum tension can be particularly difficult to overcome when opening the tensioning lever.

La présente invention a pour but d'augmenter dans une très grande mesure la relaxation du câble sans augmenter le rayon du point d'attache du câble du levier-tendeur, et tout au contraire, en utilisant un rayon relativement court permettant de tirer le meilleur parti de l'effet de levier du levier-tendeur.The object of the present invention is to increase the relaxation of the cable to a very great extent without increasing the radius of the point of attachment of the cable of the tensioning lever, and quite the contrary, by using a relatively short radius allowing the best to be obtained. leveraging the tensioner lever.

La chaussure selon l'invention est caractérisée par le fait que le support du levier-tendeur est monté coulissant sur une crémaillère à dents de rochet sur laquelle il est retenu par un cliquet contre l'action de la traction du câble relié au levier-tendeur, le cliquet étant maintenu en prise avec la crémaillère par un ressort et présentant un bras par lequel il peut être écarté manuellement de la crémaillère.The shoe according to the invention is characterized in that the support of the tensioning lever is slidably mounted on a ratchet with ratchet teeth on which it is retained by a pawl against the pulling action of the cable connected to the tensioning lever , the pawl being held in engagement with the rack by a spring and having an arm by which it can be moved manually from the rack.

Dans le sens de la fermeture, le cliquet du support du levier-tendeur saute sur les dents de rochet de la crémaillère en permettant au support du levier-tendeur de coulisser le long de la crémaillère en entraînant le câble. Le support du levier-tendeur s'arrête de lui-même lorsqu'il rencontre une certaine résistance du câble. Il suffit alors de fermer le levier-tendeur pour terminer le serrage. Inversement, l'utilisateur peut déplacer le support du levier-tendeur dans l'autre sens en le libérant de la crémaillère par une pression sur le bras du cliquet. La construction est particulièrement intéressante lorsque le levier-tendeur est utilisé pour fermer et serrer la tige de la chaussure, car dans ce cas, une longueur importante de câble peut être relâchée, ce qui permet d'obtenir une large ouverture de la chaussure.In the closing direction, the pawl of the tensioner lever holder jumps on the ratchet teeth of the rack, allowing the tensioner lever holder to slide along the rack, driving the cable. The support of the tensioner lever stops itself when it encounters a certain resistance of the cable. Then just close the tensioning lever to complete the tightening. Conversely, the user can move the support of the tensioning lever in the other direction by releasing it from the rack by pressing on the arm of the pawl. The construction is particularly advantageous when the tensioning lever is used to close and tighten the upper of the shoe, since in this case a large length of cable can be released, which makes it possible to obtain a wide opening of the shoe.

Selon une forme d'exécution préférée de l'invention, le levier-tendeur agit directement sur un câble fermant et serrant la tige de la chaussure et il est monté sur une crémaillère elle-même coulissante, dont l'extrémité opposée à la traction sur le câble de fermeture de la tige est reliée à au moins un deuxième câble utilisé pour serrer le pied. Le serrage du pied n'exigeant qu'un déplacement du câble relativement faible, le retrait de la crémaillère, de préférence limité par une butée, qui se soustrait au déplacement du point d'attache du câble de fermeture de la tige, est sans autre acceptable.According to a preferred embodiment of the invention, the tensioning lever acts directly on a cable closing and tightening the upper of the shoe and it is mounted on a rack which is itself sliding, the end opposite to the traction on the rod closing cable is connected to at least one second cable used to tighten the foot. The tightening of the foot requiring only a relatively small displacement of the cable, the withdrawal of the rack, preferably limited by a stop, which is withdrawn from the displacement of the point of attachment of the cable for closing the rod, is without further acceptable.

La chaussure sera tout d'abord décrite telle qu'elle se présente extérieurement sur les figures 1 et 2. Elle comprend un bas de coque rigide 1 venu d'une pièce avec la semelle 2 selon une conception usuelle. Sur ce bas de coque 1 est articulé en un point 3 une tige 4 comportant une partie antérieure 5 en forme de gouttière dans laquelle vient s'emboîter une partie postérieure 6. La chaussure est en outre équipée d'un chausson ou chaussure intérieure 7 destiné à assurer le confort du pied dans la chaussure. Au dos de cette chaussure, sur la partie postérieure 6 de la tige, est monté un dispositif tendeur 8 agissant simultanément sur la tige 4 pour sa fermeture et sur le pied pour son serrage. Ce dispositif 8 est constitué essentiellement d'un levier-tendeur 9 articulé sur un support 10 (fig. 2) se présentant sous la forme d'une pièce profilée en U elle-même montée sur une crémaillère 11 à dents de rochet orientées vers la bas de la chaussure. La crémaillère 11 n'est pas fixée à la chaussure, mais elle est libre verticalement, simplement guidée, en bas par une rainure 12 et en haut par un pont 13. Son ébat est toutefois limité en haut par une butée 14 et en bas par l'extrémité de la rainure 12. Le support 10 du levier 9 est retenu sur la crémaillère 11 par un cliquet 15 articulé entre les ailes du support 10, la crémaillère 11 passant donc entre le cliquet 15 et la base du support 10. Le cliquet 15 est muni d'un bras 16 permettant de l'écarter manuellement de la crémaillère 11. Au levier-tendeur 9 sont attachées les extrémités de deux câbles 17 et 18 passant dans deux guidages 19 et 20 formés sur la partie postérieure 6 de la tige et dont les autres extrémités sont fixées à la partie antérieure 5 de la tige par des plots 32 et 33. La partie postérieure 6 de la tige présente en outre des épaulements arrondis 21 et 22 pour le guidage des câbles 17 et 18. A l'extrémité inférieure de la crémaillère 11 sont attachées les extrémités de deux câbles 23 et 24 assurant le serrage du cou-de-pied et du pied.The shoe will first be described as it appears externally in Figures 1 and 2. It comprises a rigid shell bottom 1 come in one piece with the sole 2 according to a usual design. On this shell bottom 1 is articulated at a point 3 a rod 4 comprising a front part 5 in the form of a gutter in which a rear part 6 fits. The shoe is furthermore equipped with an inner shoe or shoe 7 intended to ensure the comfort of the foot in the shoe. On the back of this shoe, on the rear part 6 of the upper, is mounted a tensioning device 8 acting simultaneously on the upper 4 for its closing and on the foot for its tightening. This device 8 essentially consists of a tensioning lever 9 articulated on a support 10 (fig. 2) in the form of a U-shaped part itself mounted on a rack 11 with ratchet teeth oriented towards the bottom of the shoe. The rack 11 is not attached to the shoe, but it is free vertically, simply guided, at the bottom by a groove 12 and at the top by a bridge 13. Its clearance is however limited at the top by a stop 14 and at the bottom by the end of the groove 12. The support 10 of the lever 9 is retained on the rack 11 by a pawl 15 articulated between the wings of the support 10, the rack 11 therefore passing between the pawl 15 and the base of the support 10. The pawl 15 is provided with an arm 16 making it possible to manually separate it from the rack 11. To the tensioner lever 9 are attached the ends of two cables 17 and 18 passing in two guides 19 and 20 formed on the rear part 6 of the rod and the other ends of which are fixed to the front part 5 of the rod by studs 32 and 33. The rear part 6 of the rod also has rounded shoulders 21 and 22 for guiding the cables 17 and 18. At the lower end of the rack 11 are attached the ends of two cables 23 and 24 sure before tightening the instep and the foot.

Le dispositif de fermeture et de tension 8 sera décrit plus en détail à l'aide de la figure 3. Le levier-tendeur 9 n'est pas articulé directement sur le support 10, mais par l'intermédiaire d'une biellette 25 articulée au levier-tendeur 9 en 26 et au support 10 par un axe 27. Une extrémité du levier-tendeur 9 est par ailleurs muni d'un axe 28 pouvant se déplacer dans deux lumières 29 et 30 du support 10, sensiblement parallèlement à la crémaillère 11. L'axe 27 sert en outre de point d'attache des extrémités des câbles 17 et 18. Il est à noter que les câbles 17 et 18 pourraient être constitués d'un câble unique traversant l'axe 28. Le cliquet 15 est articulé sur le support 10 au moyen d'un axe 31 et un ressort en cor de chasse 56 monté autour de cet axe 31 maintien le bec du cliquet en prise avec les dents de la crémaillère 11. En position fermée (figure 3) le cliquet 15 est recouvert par le levier-tendeur 9. En position de relaxation (figure 2) et en position ouverte (figure 4) le cliquet 15 et son bras d'actionnement 16 sont par contre découverts.The closing and tensioning device 8 will be described in more detail with the aid of FIG. 3. The tensioning lever 9 is not articulated directly on the support 10, but by means of a link 25 articulated at the tensioner lever 9 at 26 and at the support 10 by an axis 27. One end of the tensioner lever 9 is moreover provided with an axis 28 which can move in two slots 29 and 30 of the support 10, substantially parallel to the rack 11 The axis 27 also serves as an attachment point for the ends of the cables 17 and 18. It should be noted that the cables 17 and 18 could consist of a single cable crossing the axis 28. The pawl 15 is articulated on the support 10 by means of an axis 31 and a hunting horn spring 56 mounted around this axis 31 keeps the spout of the pawl in engagement with the teeth of the rack 11. In the closed position (figure 3) the pawl 15 is covered by the tensioning lever 9. In the relaxed position (figure 2) and in the open position (figure 4) the pawl 15 and its arm actuation 16 are however discovered.

Avant de décrire le fonctionnement du dispositif de fermeture on décrira le cheminement des câbles. Celui des câbles 17 et 18 a déjà été décrit.Before describing the operation of the closing device, the cable routing will be described. That of cables 17 and 18 has already been described.

Le câble 23 est muni à l'arrière d'une tête 34 par laquelle il est retenu dans un logement de la crémaillère 11 (figure 3). Il passe ensuite sur une partie arrondie de la tige 9 puis pénètre dans le bas de coque 1 par un trou 35, en ressort latéralement par un trou 36 pour rentrer à nouveau à l'intérieur du bas de coque 1 par une fenêtre 37, puis passe sur un répartiteur de pression constitué par une plaque 38 en forme de selle de cheval, bien connue en soi et servant à répartir la pression du câble sur le cou-de-pied et le pied. Le répartiteur de pression 38 est fixé à son extrémité supérieure sur un téton intérieur 57 de la partie antérieure 5 de la tige. Le câble 23 ressort ensuite du bas de coque 1 par une fenêtre 39 (figure 4), et son extrémité est ancrée latéralement sur la partie antérieure 5 de la tige par une tête de câble 40 qui permet de modifier le point d'attache du câble relativement à la partie antérieure 5 de la tige. Ce dispositif est représenté à la figure 8. Il comprend un noyau fileté 41 fixé au câble 23 et monté dans un tube taraudé 42 solidaire de la tête 40, molletée, qui prend appui contre une portée 43 de la tige (figure 1). La rotation de la tête 40 a pour effet de déplacer le noyau 41 et par conséquent de modifier le point d'ancrage du câble 23 à la tige.The cable 23 is provided at the rear with a head 34 by which it is retained in a housing of the rack 11 (Figure 3). It then passes over a rounded part of the rod 9 then enters the bottom of the shell 1 through a hole 35, emerges laterally through a hole 36 to re-enter the interior of the bottom of the shell 1 through a window 37, then passes over a pressure distributor constituted by a plate 38 in the form of a horse saddle, well known per se and used to distribute the pressure of the cable on the instep and the foot. The pressure distributor 38 is fixed at its upper end to an internal stud 57 of the front part 5 of the rod. The cable 23 then emerges from the bottom of the shell 1 through a window 39 (FIG. 4), and its end is anchored laterally on the front part 5 of the rod by a cable head 40 which makes it possible to modify the point of attachment of the cable. relative to the front part 5 of the rod. This device is shown in Figure 8. It comprises a threaded core 41 fixed to the cable 23 and mounted in a threaded tube 42 secured to the head 40, knurled, which bears against a bearing 43 of the rod (Figure 1). The rotation of the head 40 has the effect of displacing the core 41 and consequently of modifying the anchoring point of the cable 23 to the rod.

Quant au câble 24, il est également attaché par une extrémité à la crémaillère 11 par une tête de câble 44 de la même manière que le câble 23 (figure 4). Le câble 24 est tout d'abord guidé parallèlement au câble 23, puis il pénètre dans le bas de coque 1 par un trou 45, passe dans un guidage 54, puis dans un renvoi 46 fixé à la paroi du bas de coque 1, puis sur le répartiteur de pression 38. Il passe ensuite sur un second renvoi 47 (figure 3) fixé à la paroi opposée du bas de coque 1 pour repasser ensuite sur le répartiteur de pression 38, son extrémité étant finalement attachée à une tête de câble 48 analogue à la tête de câble 40 et prenant appui sur le bas de coque 1. Le cheminement des câbles est particulièrement bien visible à la figure 5. La tête de câble 48 comprend également un tube taraudé 49 dans lequel est monté au noyau fileté 50 solidaire du câble 24. Le tube 49 peut être entraîné en rotation par une poignée 51 articulée sur la tête 48 et rabattable dans un logement ménagé dans une surépaisseur du bas de coque 1.As for the cable 24, it is also attached by one end to the rack 11 by a cable head 44 in the same manner as the cable 23 (Figure 4). The cable 24 is first of all guided parallel to the cable 23, then it enters the bottom of the shell 1 through a hole 45, passes through a guide 54, then into a return 46 fixed to the wall of the bottom of the shell 1, then on the pressure distributor 38. It then passes over a second deflection 47 (FIG. 3) fixed to the opposite wall of the bottom of the shell 1 to then pass over again on the pressure distributor 38, its end being finally attached to a cable head 48 analogous to the cable head 40 and bearing on the bottom of the shell 1. The cable routing is particularly clearly visible in FIG. 5. The cable head 48 also includes a tapped tube 49 in which is mounted to the threaded core 50 secured of the cable 24. The tube 49 can be rotated by a handle 51 articulated on the head 48 and foldable in a housing formed in an additional thickness of the bottom of the shell 1.

Le renvoi 46 est représenté en coupe à la figure 6. Il est constitué d'un bout de tôle pliée fixée au bas de coque 1 par un rivet 52.The reference 46 is shown in section in FIG. 6. It consists of a folded sheet metal end fixed to the bottom of the shell 1 by a rivet 52.

Le renvoi 47 est représenté en coupe à la figure 9. Il est constitué d'une plaquette fixée au bas de coque 1 par un rivet 53 et présentant une portée semi-circulaire pour le guidage du câble 24.The reference 47 is shown in section in FIG. 9. It consists of a plate fixed to the bottom of the shell 1 by a rivet 53 and having a semi-circular bearing for guiding the cable 24.

Le guidage 54 est représenté à la figure 7 qui est une vue en coupe de l'articulation de la tige sur le bas de coque à l'endroit du passage du câble 24. Le guidage 54 est formé par une rainure ménagée dans l'épaisseur du bas de coque 1 et fermée par une rondelle 55.The guide 54 is shown in Figure 7 which is a sectional view of the articulation of the rod on the bottom of the shell at the location of the passage of the cable 24. The guide 54 is formed by a groove made in the thickness from the bottom of the shell 1 and closed by a washer 55.

Le dispositif 8 assure donc simultanément la fermeture de la chaussure et le serrage du pied. Le fonctionnement du dispositif sera décrit en partant de la figure 4 qui représente la chaussure en position ouverte. Dans cette position, le support 10 du levier-tendeur 9 et dans la partie supérieure de la crémaillère 11. Le levier-tendeur 9 est ouvert et son axe 28 auxquels sont attachés les câbles 17 et 18 est en butée contre les extrémités supérieures des lumières 29 et 30. Dans cette position, les câbles 17 et 18 sont relâchés au maximum, ce qui permet d'ouvrir largement la chaussure en faisant basculer vers l'arrière la partie postérieure de la tige 6. La crémaillère 11 n'est pas sollicitée et les câbles 23 et 24 sont également relâchés. Pour fermer la chaussure, le skieur relève le levier-tendeur 9, ce qui a pour effet de tirer sur les câbles 17 et 18 et de fermer la tige de la chaussure. Lorsque le levier-tendeur 9 atteint une position oblique, vers le haut, une poussée axiale sur le levier 9 a pour effet d'entraîner le support 10 le long de la crémaillère 11, le cliquet 15 sautant sur les dents de cette crémaillère. Lorsque la tension sur les câbles atteint une valeur telle qu'il n'est plus possible de pousser sur le support 10, il ne reste plus qu'à rabattre complètement le levier 9 contre la chaussure pour tendre tous les câbles, la tension sur les câbles 23 et 24 étant assurée par la traction sur la crémaillère exercée par la réaction sur les câbles 17 et 18. La force avec laquelle on serre la tige est généralement supérieure à celle avec laquelle on serre le pied. C'est pourquoi le déplacement de la crémaillère 11, et par conséquent la tension sur les câbles 23 et 24, est limité par la butée 14. Le serrage du pied est particulièrement efficace en raison du fait que les câbles 23 et 24 exercent une pression sur le répartiteur de pression 38 en trois endroits différents.The device 8 therefore simultaneously ensures the closing of the shoe and the tightening of the foot. The operation of the device will be described starting from FIG. 4 which represents the shoe in the open position. In this position, the support 10 of the tensioning lever 9 and in the upper part of the rack 11. The tensioning lever 9 is open and its axis 28 to which the cables 17 and 18 are attached is in abutment against the upper ends of the lights 29 and 30. In this position, the cables 17 and 18 are loosened as much as possible, which makes it possible to open the boot widely by tilting the rear part of the upper 6 backwards. The rack 11 is not stressed and cables 23 and 24 are also released. To close the boot, the skier raises the tensioner lever 9, which has the effect of pulling on the cables 17 and 18 and closing the upper of the boot. When the tensioning lever 9 reaches an oblique position, upwards, an axial thrust on the lever 9 has the effect of driving the support 10 along the rack 11, the pawl 15 jumping on the teeth of this rack. When the tension on the cables reaches a value such that it is no longer possible to push on the support 10, it only remains to completely fold the lever 9 against the shoe to tension all the cables, the tension on the cables 23 and 24 being provided by the traction on the rack exerted by the reaction on cables 17 and 18. The force with which the rod is tightened is generally greater than that with which the foot is clamped. This is why the movement of the rack 11, and consequently the tension on the cables 23 and 24, is limited by the stop 14. The clamping of the foot is particularly effective due to the fact that the cables 23 and 24 exert pressure on the pressure distributor 38 in three different places.

Si le skieur désire desserrer sa chaussure sans toutefois déchausser, il lui suffit d'ouvrir le levier-tendeur 9 comme représenté à la figure 2. Dans cette position, tous les câbles sont relâchés mais le support 10 ne c'est pas déplacé sur la crémaillère 11, de sorte que le réglage de la tension est conservé. Il suffira au skieur de refermer le levier 9 pour retrouver les conditions de ski précédentes.If the skier wishes to loosen his shoe without however taking off his shoes, he just has to open the tensioning lever 9 as shown in FIG. 2. In this position, all the cables are released but the support 10 is not moved on the rack 11, so that the tension setting is retained. It will be sufficient for the skier to close the lever 9 to find the previous skiing conditions.

Pour déchausser, l'utilisateur n'a qu'à presser sur le bras 16 du cliquet 15 pour le libérer de la crémaillère 11 et simultanément tirer le levier 9 vers le haut pour entraîner le support 10 vers le haut de la crémaillère 11, pour retrouver la position représentée à la figure 4.To remove the shoes, the user only has to press on the arm 16 of the pawl 15 to release it from the rack 11 and simultaneously pull the lever 9 upwards to drive the support 10 upwards of the rack 11, to find the position shown in Figure 4.

L'exécution représentée est particulièrement avantageuse pour au moins deux raisons. Tout d'abord, étant donné que le levier-tendeur 9 se ferme vers le haut, en position de serrage maximum, il ne dépasse que très peu la crémaillère 11, permettant sans autre de respecter les normes internationales relatives à l'espace qui doit être laissé libre au-dessus du talon. D'autre part, les câbles 17 et 18 étant attachés au point de rotation du levier-tendeur 9 sur son support 10, la tension sur les câbles croit de façon continue jusqu'à la fermeture complète du levier-tendeur 9, ce qui ne serait pas le cas si l'on utilisait un levier simple, sans la biellette 25 et un point d'attache du câble 17 et 18 au levier-tendeur situé entre son axe d'articulation et son extrémité.The execution shown is particularly advantageous for at least two reasons. First of all, given that the tensioning lever 9 closes upwards, in the maximum tightening position, it only slightly exceeds the rack 11, allowing without other to respect the international standards relating to the space which must be left free above the heel. On the other hand, the cables 17 and 18 being attached to the point of rotation of the tensioning lever 9 on its support 10, the tension on the cables increases continuously until the complete closing of the tensioning lever 9, which does not would not be the case if a simple lever were used, without the link 25 and a point of attachment of the cable 17 and 18 to the tensioning lever located between its axis of articulation and its end.

Selon une variante non représentée et évidente, il serait bien entendu possible d'utiliser un levier-tendeur à un seul axe d'articulation sur son support et se fermant de haut en bas. Dans une exécution encore plus simplifiée, sans serrage du pied, la crémaillère 11 pourrait être fixe. On aurait toutefois déjà dans ce cas l'avantage d'un support de levier-tendeur coulissant assurant une grande relaxation des câbles 17 et 18 tout en ayant un petit rayon de giration des points d'attache des câbles du levier-tendeur, c'est-à-dire une utilisation optimale de l'effet de levier du levier-tendeur.According to a variant not shown and obvious, it would of course be possible to use a tensioning lever with a single hinge pin on its support and closing from top to bottom. In an even more simplified embodiment, without clamping the foot, the rack 11 could be fixed. In this case, however, there would already be the advantage of a sliding lever-tensioner support ensuring great relaxation of the cables 17 and 18 while having a small radius of gyration of the attachment points of the cables of the tensioner lever, it i.e. optimal use of the leverage of the tensioner lever.

La crémaillère 11 peut être sans autre réalisée en matière synthétique.The rack 11 can be without other made of synthetic material.
