Description

9 7 9 5 6 0 La présente invention concerne une clé plate à cliquets réversible et à commande de rotation alternative pour visser/dévisser des écrous sur raccords de tuyauteries et raccords hydrauliques: tubes filetés , manchons , Les clés plates simples nécessitent un dégagement pour repositionnement sur l'écrou après chaque rotation. Les clés à cliquet traditionnelles doivent être maintenues manuellement en contact/maintien sur l'écrou pour éviter des retraits ou repositionnement Le couple de serrage ne s'exerce généralement que sur 2pans de l'écrou le dispositif selon l'invention, permet de remédier à ces inconvénients. la clé se positionne en radial sur l'écrou ou d'abord en radial sur le tuyau, puis en longitudinal sur l'écrou L'ouverture du bec de la fourche est dimensionnée pour être supérieur au diamètre du tuyau mais inférieure ou supérieur à la dimension sur pan de l' écrou dont la clé reste solidaire pendant toutes les rotations alternatives. tant que un dégagement axial n'a pas été effectué via le tuyau fileté en extrémité Le couple de serrage s'exerce sur 1 ou 4 pan de l'écrou ce qu'il permet dans sa catégorie d'outillage, un contact avec un maximum de surfaces de préhension par cliquets(1) pour une meilleure répartition des contraintes et efforts et un risque moindre de détérioration des arêtes de l'écrou Une tête de clé est composée d'un support en forme de fourche légèrement refermée aux extrémités( type mâchoire) la fourche est évidée pour permettre le positionnement et le montage des cliquets et des ressorts (conique ou compression, torsion) de rappel des cliquets les cliquets, disposés en cotés et en fond de fourche suivant la configuration hexagonale des écrous fonctionnent, avec les ressorts: 1-en arc-boutement sur le pan d'écrou en action d'effort: serrage ou desserrage 2- en position escamotée pour repositionnement de la clé en rotation une tête de clé accepte une plage limitée de dimensions tube/ écrou 3- les cliquets viennent en talonnage sur l'évidemment quelque soit la position de celui: ci pour éviter la surcharge des axes à la rupture ( système de coin ) En fonction des coûts d'industrialisation et des attentes des utilisateurs potentiels, 2 types de raccordement manche-tête de clé sont possibles 1 - le manche est solidaire de la tête de clé, avec possibilité de tête à chaque extrémité du manche et acceptant des dimensions d'écrous différentes ( principe des clés plates standard) 2-des têtes de clé se terminant par une tige hexagonale, adaptable par encliquetage sur un manche unique de forme cylindrique. le manche présent également la caractéristique d'être télescopique pour autoriser les accès en espaces restreints ou pour des bras de leviers nécessitant des efforts plus importants. Les dessins annexés illustrent l'invention et son mode d'utilisation: la figure let 5 représente en vue de face le dispositif del 'invention, ainsi que le positionnement et les spécificités de l' invention par rapport aux éléments physiques à manoeuvrer en situation d'effort(vissage/dévissage) La figure 2 et 4 représente en vue de face le même dispositif en situation de repositionnement sans effort en rotation sur l'écrou La figure 6représente en perspective la clé avec un manette réversible(14) et 2 cliquets commande par un levier pour change le sens d'effort ( vissage/ dévissage) le bouton réversible sollicite le moyen d'activation et de désactivation des cliquets En référence à ces dessins, le dispositif comporte un manche(11) solidaire de la tête (9) La cote d'ouverture du bec(b) est supérieure au diamètre(a)du tube(5) pour pouvoir permettre la première phase d'insertion radiale de la clé. Cette même cote (b)est inférieur à la cote sur pan ( c) de l'écrou ( 4) pour éviter que la clé ne se désolidarise de l'écrou( 4) lors des rotations alternatives la tête de clé (9) est évidée (10), environ à mi-épaisseur pour permettre le montage et le positionnement des cliquets (1) et des ressorts (conique ou compression , torsion) (2) lors de la fabrication de la clé .les cliquets de forme polygonale adaptée sont maintenus en rotation dans la cavité évidée (10) de la tête(9) par des axes(3) Dans le sens effort de vissage ou dévissage, le ressort (2) vient appliquer le cliquet(1) sur le pan de l'écrou(4) pour serrage ou desserrage Dans le sens repositionnement de la clé, c'est le pan de l'écrou(4) qui vient prendre appui sur le cliquet(1) pour comprimer le ressort (2) et permettre un repositionnement sans effort(figure 2 et 4) The present invention relates to a reversible ratchet and reciprocating rotary ratchet for screwing / unscrewing nuts on hydraulic pipe fittings and fittings: threaded tubes, sleeves, simple flat wrenches require clearance for repositioning on the nut after each rotation. The traditional ratchet wrenches must be held manually in contact / hold on the nut to avoid withdrawals or repositioning The tightening torque is generally exerted only on 2 sides of the nut the device according to the invention, makes it possible to remedy these disadvantages. the key is positioned radially on the nut or first radially on the pipe, then longitudinally on the nut The opening of the fork spout is dimensioned to be greater than the pipe diameter but less than or greater than the diameter of the pipe. dimension on the pan of the nut whose key stays in solidarity during all the alternative rotations. until an axial clearance has been made via the threaded pipe at the end The tightening torque is exerted on 1 or 4 pan of the nut which it allows in its category of tools, a contact with a maximum ratchet grip surfaces (1) for a better distribution of stresses and stresses and a lower risk of damage to the edges of the nut A key head is composed of a fork-shaped support slightly closed at the ends (jaw type ) the fork is recessed to allow the positioning and the assembly of the pawls and the springs (conical or compression, torsion) of return of the pawls the pawls, arranged in sides and in bottom of fork according to the hexagonal configuration of the nuts work, with the springs : 1-on the nut section in force action: tightening or loosening 2- in the retracted position to reposition the key in rotation a key head accepts a limited range tube / nut dimensions 3 - the pawls are in calibration on the obviously whatever the position of this one: ci to avoid the overload of the axes to break (system of corner) According to the costs of industrialization and the expectations of the users potential, 2 types of handle-head connection are possible 1 - the handle is integral with the key head, with possibility of head at each end of the handle and accepting different sizes of nuts (principle of the standard flat keys) 2 key heads ending in a hexagonal rod, adaptable by snapping on a single cylindrical handle. the handle also has the feature of being telescopic to allow access in tight spaces or for lever arms requiring greater effort. The accompanying drawings illustrate the invention and its mode of use: FIG. 5 represents in front view the device of the invention, as well as the positioning and the specific features of the invention with respect to the physical elements to be maneuvered in a situation of 'effort (screwing / unscrewing) Figure 2 and 4 shows a front view of the same device in repositioning situation without effort in rotation on the nut Figure 6represents in perspective the key with a reversible handle (14) and 2 ratchets by a lever for changing the direction of effort (screwing / unscrewing) the reversible button requests the means for activating and deactivating the pawls With reference to these drawings, the device comprises a handle (11) integral with the head (9) The opening dimension of the spout (b) is greater than the diameter (a) of the tube (5) to allow the first phase of radial insertion of the key. This same dimension (b) is lower than the dimension on pan (c) of the nut (4) to prevent the key from becoming detached from the nut (4) during alternative rotations the key head (9) is recess (10), about mid-thickness to allow the mounting and positioning of the pawls (1) and the springs (conical or compression, torsion) (2) during the manufacture of the key. the ratchets of suitable polygonal shape are maintained in rotation in the recessed cavity (10) of the head (9) by axes (3) In the tightening or unscrewing force direction, the spring (2) comes to apply the pawl (1) on the side of the nut (4) for tightening or loosening In the repositioning direction of the key, it is the part of the nut (4) which bears on the pawl (1) to compress the spring (2) and allow a repositioning effortlessly (Figure 2 and 4)
