Abstract
Description
La présente invention a pour objet un tendeur mobile pour câbles. The present invention relates to a mobile tensioner for cables.
Ce type de tendeur est utilisé dans une multitude d'installations, son application la plus importante résidant dans le domaine nautique, plus spécialement dans le domaine des voiliers, dans lesquels ils sont utilisés pour appliquer une tension variable à divers câbles. This type of tensioner is used in a multitude of installations, its most important application residing in the nautical field, more especially in the field of sailboats, in which they are used to apply a variable tension to various cables.
Les dispositifs tendeurs déjà existants présentent une construction sujette à se dérégler, des défauts d'étanchéité qui sont à l'origine de grippages par oxydation et un couple de réaction qui entraîne un grand défaut de précision dans leur manipulation. The already existing tensioning devices have a construction subject to adjustment, leaks which are the cause of seizures by oxidation and a reaction torque which results in a great lack of precision in their handling.
Pour résoudre ces problèmes, on a réalisé un nouveau tendeur mobile pour câbles dans lequel toutes les déficiences qui affectent les appareils antérieurs sont supprimées, d'une part, grâce à un ingénieux dispositif d'engrenages qui agit directement sur la vis centrale, ce qui supprime le couple de réaction et, d'autre part, grâce à l'utilisation d'un boîtier d'engrenages entièrement fermé, et au fait que l'ouverture du piston mobile est dirigée vers le bas, ce qui a permis d'obtenir un ensemble absolument étanche, qui résout les problèmes de corrosion. To solve these problems, a new mobile tensioner for cables has been produced in which all the deficiencies which affect the prior devices are eliminated, on the one hand, thanks to an ingenious gear device which acts directly on the central screw, which eliminates the reaction torque and, on the other hand, thanks to the use of a fully closed gearbox, and to the fact that the opening of the movable piston is directed downwards, which has made it possible to obtain an absolutely waterproof set, which solves corrosion problems.
Le fonctionnement du nouveau tendeur est basé sur l'actionnement, au moyen d'une manivelle, d'un couple de pignons coniques qui transmettent le mouvement à un arbre fileté, lequel.fait monter ou descendre un piston selon qu'on le fait tourner vers la gauche ou vers la droite. The operation of the new tensioner is based on the actuation, by means of a crank, of a couple of bevel gears which transmit the movement to a threaded shaft, which raises or lowers a piston according to whether it is rotated. to the left or to the right.
D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre, d'un exemple de réalisation et en se référant au dessin annexé. Other characteristics and advantages of the invention will be better understood on reading the description which follows, of an exemplary embodiment and with reference to the attached drawing.
Dans la forme de réalisation représentée sur le dessin, le tendeur pour câbles selon l'invention est composé de deux ancrages 1 et 2 auxquels se fixe le câble auquel il s'agit de donner de la tension. In the embodiment shown in the drawing, the cable tensioner according to the invention is composed of two anchors 1 and 2 to which the cable to which tension is to be attached is attached.
L'ancrage supérieur est vissé dans la partie haute du boîtier d'engrenages 3 à l'intérieur duquel est agencé un couple conique comprenant un pignon vertical 4 solidaire d'un cylindre 5 dans lequel s'emboîte une manivelle, et dont le mouvement est transmis à un arbre fileté 6 au moyen d'un pignon horizontal 7 qui engrène dans le pignon vertical et est monté sur un palier ou roulement 8. The upper anchor is screwed into the upper part of the gearbox 3 inside which a bevel gear is arranged comprising a vertical pinion 4 secured to a cylinder 5 in which a crank fits, and whose movement is transmitted to a threaded shaft 6 by means of a horizontal pinion 7 which meshes in the vertical pinion and is mounted on a bearing or bearing 8.
Ledit bottier d'engrenages est fermé par un bouchon 9 pour donner naissance à un ensemble totalement étanche. t'arbre fileté est protégé par une pièce tubulaire 10. Dans la partie inférieure de cette pièce, se trouve un joint étanche 11 présentant une clavette 12 qui est engagée dans une rainure de guidage 13 prévue sur le piston 14. te piston est vissé sur l'arbre fileté et se déplace sur ce dernier lorsque l'arbre tourne, du fait que la rotation du piston est bloquée par la rainure et par la clavette. Said gear case is closed by a plug 9 to give rise to a completely sealed assembly. the threaded shaft is protected by a tubular part 10. In the lower part of this part, there is a tight seal 11 having a key 12 which is engaged in a guide groove 13 provided on the piston 14. The piston is screwed on the threaded shaft and moves on the latter when the shaft rotates, because the rotation of the piston is blocked by the groove and by the key.
Pour éviter que le piston ne s'échappe de l'arbre fileté, on a prévu une butée 15. To prevent the piston from escaping from the threaded shaft, a stop 15 has been provided.
Bien entendu, diverses modifications pourront être apportées par l'homme de l'art au dispositif qui vient d'être décrit uniquement à titre d'exemple non limitatif, sans sortir du cadre de l'invention. Of course, various modifications may be made by those skilled in the art to the device which has just been described solely by way of non-limiting example, without departing from the scope of the invention.
