La clé à sangle pour filtre à huile représentée aux Figures 1 à 11 comprend essentiellement un corps d'appui 1, une sangle 2, une tige filetée 3 et une poignée 4.The strap wrench for oil filter shown in Figures 1 to 11 essentially comprises a support body 1, a strap 2, a threaded rod 3 and a handle 4.

Le corps 1 est une pièce métallique moulée comportant extérieurement une face d'appui supérieure 5 cylindrique, à section longitudinale (Figure 2) sensiblement circulaire, deux faces d'extrémité 6 planes et parallèles, de forme générale triangulaire, reliées respectivement aux extrémités axiales de la face 5, et deux faces latérales obliques 7 reliant les faces 6. A sa base, le corps comporte un embout tubulaire 8 qui se termine intérieurement par un épaulement radial annulaire 9 et qui comporte intérieurement, à peu près à mi-hauteur, une gorge circulaire 10.The body 1 is a molded metal piece externally comprising a cylindrical upper support face 5, with a longitudinal section (Figure 2) substantially circular, two end faces 6 flat and parallel, of generally triangular shape, connected respectively to the axial ends of the face 5, and two oblique lateral faces 7 connecting the faces 6. At its base, the body comprises a tubular end piece 8 which ends internally by an annular radial shoulder 9 and which internally comprises, approximately at mid-height, a circular groove 10.

Dans sa partie courante, au-dessus de l'épaulement 9, le corps comporte un alésage vertical circulaire 11 de même axe vertical X-X que l'alésage de l'embout 8, mais de diamètre nettement plus petit, et débouchant dans ce dernier. Du côté de chaque face 7, l'alésage 11 est bordé d'une rainure 12 à section rectangulaire de largeur constante, dont le fond 13 s'éloigne progressivement de l'axe X-X, suivant une courbe convexe à peu près circulaire (Figure 2), à partir de l'épaulement 9. Les parois latérales 14 de ces rainures sont coplanaires deux à deux et parallèles aux faces 6.In its main part, above the shoulder 9, the body has a circular vertical bore 11 with the same vertical axis XX as the bore of the endpiece 8, but of a diameter much smaller, and opening into the latter. On the side of each face 7, the bore 11 is bordered by a groove 12 of rectangular section of constant width, the bottom 13 of which gradually moves away from the axis XX, along a roughly circular convex curve (FIG. 2), starting from the shoulder 9. The side walls 14 of these grooves are coplanar in pairs and parallel to the faces 6.

Une traverse 15 venue de matière, formant butée, perpendiculaire à l'axe X-X, relie les faces 14 dans la région de cet axe, en un emplacement adjacent à la face d'appui 5. La face supérieure de cette traverse prolonge d'ailleurs exactement cette face 5.A cross member 15 made of material, forming a stopper, perpendicular to the axis XX, connects the faces 14 in the region of this axis, at a location adjacent to the bearing face 5. The upper face of this cross member also extends exactly this side 5.

La sangle 2 est une ruban métallique ayant sensiblement la même largeur que les rainures 12 et dont les deux extrémités sont perforées. Dans le cas de la Figure 6, qui est également celui des Figures 10 et 11, la tige filetée 3 comporte une partie supérieure d'épaisseur réduite, définissant deux faces planes et parallèles 16, percée d'un orifice 17. En appliquant les deux extrémités de la sangle sur ces deux faces 16, on assure la fixation de la sangle sur la tige filetée au moyen d'un organe de fixation approprié, par exemple, comme représenté, d'un boulon 18 à écrou 19.The strap 2 is a metal strip having substantially the same width as the grooves 12 and the two ends of which are perforated. In the case of FIG. 6, which is also that of FIGS. 10 and 11, the threaded rod 3 comprises an upper part of reduced thickness, defining two plane and parallel faces 16, pierced with an orifice 17. By applying the two ends of the strap on these two faces 16, the strap is fixed to the threaded rod by means of a suitable fixing member, for example, as shown, of a bolt 18 with nut 19.

Dans la variante de la Figure 7, la partie supérieure de la tige filetée est fendue diamétralement en 20 pour recevoir les deux extrémités accolées de la sangle, et la fixation est assurée par un organe approprié, par exemple une goupille fendue 21 qui traverse à force un passage transversal 22 de la partie fendue de la tige filetée ainsi que les trous de la sangle.In the variant of FIG. 7, the upper part of the threaded rod is split diametrically at 20 to receive the two adjoining ends of the strap, and the fixing is ensured by a suitable member, for example a split pin 21 which forcibly crosses a transverse passage 22 of the slotted part of the threaded rod as well as the holes of the strap.

La poignée 4 comporte sur presque toute sa longueur un alésage borgne taraudé 23 débouchant sur une face plane et horizontale supérieure 24 de la poignée. Extérieurement, la poignée présente, de haut en bas : une partie cylindrique lisse 25 conjuguée de l'alésage de l'embout 8 et se terminant par un épaulement radial 26; une collerette 27 adjacente à cet épaulement; une courte partie concave 28; une partie convexe 29 s'étendant sur la majeure partie de la longueur de la poignée; et une courte partie concave 30 plus courte que la partie 28. Trois logements radiaux pour des billes 31 chargées par des ressorts sont prévus dans la partie cylindrique 25, et l'extrémité inférieure de la poignée comporte une saillie 32 en forme de six-pans pour permettre l'actionnement de la poignée avec un outil de serrage.The handle 4 comprises over almost its entire length a tapped blind bore 23 opening onto a flat, horizontal upper face 24 of the handle. Externally, the handle has, from top to bottom: a smooth cylindrical part 25 combined with the bore of the end piece 8 and ending in a radial shoulder 26; a flange 27 adjacent to this shoulder; a short concave portion 28; a convex part 29 extending over most of the length of the handle; and a short concave part 30 shorter than the part 28. Three radial housings for balls 31 loaded by springs are provided in the cylindrical part 25, and the lower end of the handle has a projection 32 in the form of a hexagon to allow actuation of the handle with a clamping tool.

Pour monter l'outil, on introduit de haut en bas les deux extrémités de la sangle dans le corps 1, de part et d'autre de la traverse 15, jusqu'à ce qu'elles émergent sous le corps. On les fixe alors à la tige filetée 3, suivant l'une ou l'autre des variantes des Figures 6 et 7.To mount the tool, the two ends of the strap are introduced from top to bottom into the body 1, on either side of the cross-member 15, until they emerge under the body. They are then fixed to the threaded rod 3, according to one or other of the variants of FIGS. 6 and 7.

On visse ensuite la poignée sur la tige filetée, puis on emboîte la partie 25 de la poignée dans l'embout 8. Lorsque cette partie 25 bute contre l'épaulement 9, les billes 31 viennent en prise dans la gorge 10.The handle is then screwed onto the threaded rod, then the part 25 of the handle is fitted into the end piece 8. When this part 25 abuts against the shoulder 9, the balls 31 engage in the groove 10.

Dans cette situation, la poignée est solidarisée axialement du corps 1 mais peut tourner par rapport à celui-ci, et les deux parties de la sangle situées dans le corps 1 sont bien guidées latéralement par les faces 14 des rainures 12, et s'appliquent d'elles-mêmes, du fait de leur élasticité, sur les faces courbes 13.In this situation, the handle is axially secured to the body 1 but can rotate relative to the latter, and the two parts of the strap located in the body 1 are well guided laterally by the faces 14 of the grooves 12, and are applied of themselves, due to their elasticity, on the curved faces 13.

Pour dévisser un filtre à huile, on dévisse la poignée 4, dans le sens anti-horaire, en tenant le corps 1, jusqu'à ce que la partie libre de la sangle ait un diamètre suffisant. On enfile alors la sangle sur le filtre à huile, puis on visse la poignée, en tenant le corps 1, ce qui provoque le déplacement de la tige filetée 3 vers le fond de l'alésage 23. On poursuit ce mouvement jusqu'à ce que la face d'appui 5 soit appliquée sur le filtre et que ce dernier soit fermement serré par la sangle, puis on dévisse ce dernier en agissant sur la poignée perpendiculairement à l'axe du filtre, c'est-à-dire suivant la flèche f de la Figure 8.To unscrew an oil filter, unscrew the handle 4, anti-clockwise, holding the body 1, until the free part of the strap has a sufficient diameter. The strap is then put on the oil filter, then the handle is screwed in, holding the body 1, which causes the displacement of the threaded rod 3 towards the bottom of the bore 23. This movement is continued until that the bearing face 5 is applied to the filter and that the latter is firmly tightened by the strap, then the latter is unscrewed by acting on the handle perpendicular to the axis of the filter, that is to say according to arrow f in Figure 8.

La conception de l'outil décrite ci-dessus permet d'obtenir, pour un encombrement donné de l'outil, une longue course de la tige filetée 3, qui n'a pas besoin d'être de grande longueur, et donc une grande gamme de diamètres utiles pour la sangle. De plus, l'outil ne présente pas d'aspérités risquant de s'accrocher sur les organes voisins du filtre à huile ou de blesser l'opérateur, et le galbe de la poignée offre une grande commodité d'utilisation : les parties avant et arrière concaves 28 et 30 permettent un calage des doigts pour le serrage/desserrage de la poignée, tandis que la partie principale convexe 29 se loge dans la paume de la main pour faciliter le dévissage du filtre à huile.The design of the tool described above makes it possible to obtain, for a given size of the tool, a long stroke of the threaded rod 3, which does not need to be of great length, and therefore a great range of useful diameters for the strap. In addition, the tool does not have any rough edges which could catch on the neighboring parts of the oil filter or injure the operator, and the curve of the handle offers great convenience of use: the front and concave rear 28 and 30 allow a wedging of the fingers for tightening / loosening of the handle, while the main convex part 29 is housed in the palm of the hand to facilitate the unscrewing of the oil filter.

Lors du dévissage de la poignée par rapport au corps, la tige filetée 3 peut sortir presque entièrement de la poignée et est guidée par l'alésage 11. Cependant, la sangle ne risque pas d'être perdue, grâce à la présence de la traverse 15, contre laquelle vient buter la tige 3 ou la sangle 2.When unscrewing the handle relative to the body, the threaded rod 3 can come out almost entirely from the handle and is guided by the bore 11. However, the strap is not likely to be lost, thanks to the presence of the crosspiece 15, against which abuts the rod 3 or the strap 2.

Il est à noter que l'agencement de la Figure 6 semble actuellement plus avantageux que celui de la Figure 7, car l'écartement des extrémités de la sangle favorise la bonne application de celle-ci sur le fond 13 des rainures 12, notamment pour le travail sur des filtres de petits diamètres.It should be noted that the arrangement of Figure 6 currently seems more advantageous than that of Figure 7, because the spacing of the ends of the strap promotes the proper application of the latter on the bottom 13 of the grooves 12, in particular for work on small diameter filters.

La variante des Figures 12 et 13 ne diffère de la précédente que par les points suivants.The variant of Figures 12 and 13 differs from the previous one only in the following points.

D'une part, la traverse 15 est remplacée par deux trous alignés 15A dans lesquels on fixe une butée rapportée amovible telle qu'une vis 15B à tête fraisée ou une goupille fendue 15C (Figure 13). Ceci permet de changer la sangle sans démonter la poignée du corps d'appui.On the one hand, the cross member 15 is replaced by two aligned holes 15A in which a removable attached stopper is fixed such as a screw 15B with a countersunk head or a cotter pin 15C (Figure 13). This allows the strap to be changed without removing the handle from the support body.

D'autre part, l'embout 8 est conformé en pièce mâle et s'emboîte dans un contre-alésage de la poignée prévue à l'entrée de l'alésage 23. Pour la solidarisation axiale des deux pièces, un jonc fendu 31A est reçu partiellement dans une gorge extérieure 10A de l'embout 8 et partiellement dans une gorge intérieure 10B du contre-alésage de la poignée, lorsque l'embout 8 bute contre le fond de ce contre-alésage.On the other hand, the tip 8 is shaped as male part and fits into a counter-bore of the handle provided at the entrance to the bore 23. For the axial joining of the two parts, a split rod 31A is partially received in an external groove 10A of the end piece 8 and partially in an inner groove 10B of the counterbore of the handle, when the end piece 8 abuts against the bottom of this counterbore.

Le dispositif des Figures 14, 17, 18 et 19 comporte principalement un flexible ou sangle 101 relié par ses deux extrémités à une tige filetée 104 qui coulisse avec un très petit jeu dans le corps moulé 102, percé de part en part d'un trou cylindrique lisse 103, évasé ou rainuré dans le plan de coupe d'une forme rectangulaire côté filtre, pour guider et faciliter le glissement du flexible 101.The device of Figures 14, 17, 18 and 19 mainly comprises a hose or strap 101 connected by its two ends to a threaded rod 104 which slides with a very small play in the molded body 102, drilled right through a hole smooth cylindrical 103, flared or grooved in the cutting plane of a rectangular shape on the filter side, to guide and facilitate the sliding of the hose 101.

La pièce 102 moulée, par exemple en alliage léger ou en matière plastique, comporte principalement un cylindre percé de part en part d'un trou lisse de diamètre très légèrement supérieur au diamètre de la tige filetée et de deux ailes 108 et 109 permettant la création d'une forme cylindrique partielle 110 ayant pour axe et pour diamètre approximatif ceux du filtre, afin d'en épouser la forme pour faciliter le serrage. Le trou lisse 103 de diamètre très légèrement supérieur au diamètre de la tige filetée 104 peut être constitué d'un insert notamment métallique 114, voir Figure 17, ce qui aurait pour avantage de diminuer l'usure dans la pièce 102 et de renforcer sa rigidité.The molded part 102, for example made of light alloy or plastic, mainly comprises a cylinder pierced right through with a smooth hole of diameter very slightly greater than the diameter of the threaded rod and two wings 108 and 109 allowing the creation of a partial cylindrical shape 110 having for axis and approximate diameter those of the filter, in order to follow the shape thereof to facilitate tightening. The smooth hole 103 with a diameter very slightly greater than the diameter of the threaded rod 104 may consist of a particularly metallic insert 114, see Figure 17, which would have the advantage of reducing wear in the part 102 and reinforcing its rigidity .

La poignée cylindrique 106, percée de part en part d'un trou taraudé, se visse sur la tige filetée 104 assurant sa traction et celle du flexible 101 qui peut serrer fortement le filtre encerclé. Dans le cas d'une poignée 106 en alliage d'aluminium ou en matière plastique, la partie taraudée peut être rapportée (insert métallique 113 par exemple), voir Figure 17, ce qui aurait pour avantage de diminuer l'usure dans la poignée 106 et de renforcer la rigidité. La poignée 106 peut être moletée pour augmenter l'adhérence de la main.The cylindrical handle 106, pierced right through with a tapped hole, is screwed onto the threaded rod 104 ensuring its traction and that of the hose 101 which can strongly tighten the encircled filter. In the case of a handle 106 made of aluminum alloy or plastic, the threaded part can be attached (metal insert 113 for example), see Figure 17, which would have the advantage of reducing wear in the handle 106 and strengthening the rigidity. The handle 106 can be knurled to increase the grip of the hand.

La poignée 106 et le corps 102, principalement de forme cylindrique et de même diamètre, sont bout à bout, sans pénétration, coaxiaux et centrés par la tige filetée 104.The handle 106 and the body 102, mainly of cylindrical shape and of the same diameter, are end to end, without penetration, coaxial and centered by the threaded rod 104.

Une rainure circulaire 111, d'une faible largeur et d'une profondeur de 2 à 4 mm, est pratiquée à l'extrémité de la pièce 106, côté pièce 102, à une distance d'environ 3 à 5 mm. Une rainure circulaire 112 d'une faible largeur et d'une profondeur de 2 à 4 mm est pratiquée à l'extrémité de la pièce 102, côté pièce 106, à une distance d'environ 3 à 5 mm. Une bague circulaire 105, voir Figure 15 et figure 16 (agrandissement des rainures et de la pièce 105), de section principalement en U, vient se positionner et se fixer dans ces deux rainures, empêchant les pièces 102 et 106 de se séparer (contact plan), tout en autorisant la rotation de 106 par rapport à 102 suivant l'axe principal du dispositif défini par la tige filetée 104. La bague 105 peut être en matière suffisamment élastique pour se monter par déformation ou, si elle est rigide, par cerclage et soudure.A circular groove 111, of a narrow width and a depth of 2 to 4 mm, is formed at the end of the part 106, on the part side 102, at a distance of approximately 3 to 5 mm. A circular groove 112 of a small width and a depth of 2 to 4 mm is made at the end of the part 102, on the part side 106, at a distance of approximately 3 to 5 mm. A circular ring 105, see FIG. 15 and FIG. 16 (enlargement of the grooves and of the part 105), of mainly U-shaped section, is positioned and fixed in these two grooves, preventing the parts 102 and 106 from separating (contact plan), while allowing the rotation of 106 relative to 102 along the main axis of the device defined by the threaded rod 104. The ring 105 may be made of a sufficiently elastic material to be mounted by deformation or, if it is rigid, by strapping and welding.

La tige 104 est fendue à son extrémité, côté flexible, dans un plan diamétral, d'une rainure d'environ 1 à 2 mm de largeur, sur une longueur de 8 à 15 mm, afin de permettre l'engagement des deux extrémités du flexible 101 et leur fixation, soit par un rivet 103, soit par une soudure ou par tout autre moyen économique et robuste.The rod 104 is slotted at its end, flexible side, in a diametral plane, with a groove of approximately 1 to 2 mm in width, over a length of 8 to 15 mm, in order to allow the engagement of the two ends of the flexible 101 and their fixing, either by a rivet 103, or by welding or by any other economical and robust means.

Un bouchon 107, vissé, forcé, ou collé dans le trou taraudé de la pièce 106, obstrue l'extrémité opposée à la pièce 102 pour empêcher toute pénétration dans le dispositif et également pour l'esthétique et la sécurité de l'opérateur.A plug 107, screwed, forced, or glued into the tapped hole of the part 106, obstructs the end opposite to the part 102 to prevent any penetration into the device and also for the aesthetics and the safety of the operator.

Le flexible 101 peut être constitué d'un câble ou d'une bandelette, de faible épaisseur, d'une largeur de 5 à 12 mm, très résistante à la traction et au pliage, et de bonne adhérence. Pour augmenter l'adhérence, on peut utiliser soit un revêtement, soit la création d'aspérités par frappe ou découpage.The flexible 101 can be made up of a cable or a strip, thin, with a width of 5 to 12 mm, very resistant to traction and bending, and of good adhesion. To increase the adhesion, one can use either a coating, or the creation of asperities by striking or cutting.

Le flexible 101 est de longueur variable suivant une plage de diamètres de filtre. Les diamètres de filtre varient en général de 60 à 120 mm. Plusieurs plages seront à prévoir.The hose 101 is of variable length according to a range of filter diameters. The filter diameters generally vary from 60 to 120 mm. Several beaches will be expected.

Les diamètres égaux des pièces 102 et 106 doivent être choisis de façon à permettre une bonne prise de main, par exemple entre 20 et 50 mm. La longueur des pièces 102 et 106 bout à bout doit assurer également une bonne prise de la main (longueur totale supérieure à la largeur d'une main pour former une poignée acceptable) et sera fonction de l'encombrement moteur dans la zone du filtre et de son diamètre.The equal diameters of the parts 102 and 106 must be chosen so as to allow a good grip, for example between 20 and 50 mm. The length of the parts 102 and 106 end to end must also ensure good grip of the hand (total length greater than the width of one hand to form an acceptable handle) and will be a function of the engine space in the filter area and of its diameter.

La tige filetée 104 reste, en toutes positions, à l'intérieur du dispositif. La longueur de celle-ci est égale à deux fois son diamètre plus la longueur de la poignée 106, et est nettement inférieure à la longueur des pièces 102 et 106 placées bout à bout. La tige filetée 104 peut pénétrer dans le dispositif jusqu'à son contact avec le bouchon 107. Le taraudage de part en part de la poignée 106 favorise la course de la tige filetée 104. Plusieurs calibres de ce dispositif peuvent être proposés en fonction des diamètres de filtre et de l'espace moteur libre dans la zone du filtre.The threaded rod 104 remains, in all positions, inside the device. The length of the latter is equal to twice its diameter plus the length of the handle 106, and is much less than the length of the parts 102 and 106 placed end to end. The threaded rod 104 can penetrate the device until it comes into contact with the plug 107. The tapping right through the handle 106 promotes the stroke of the threaded rod 104. Several calibers of this device can be offered depending on the diameters filter and free engine space in the filter area.

Le dispositif des Figures 20 à 23 comporte principalement un flexible ou sangle 201 relié par ses deux extrémités à une tige filetée 204 qui coulisse (translation) avec un jeu radial de l'ordre de 2 mm dans un trou cylindrique 213. Ce jeu radial facilite le glissement du flexible 201 pour sa pénétration et son dégagement.The device of Figures 20 to 23 mainly comprises a hose or strap 201 connected by its two ends to a threaded rod 204 which slides (translation) with a radial clearance of the order of 2 mm in a cylindrical hole 213. This radial clearance facilitates the sliding of the flexible 201 for its penetration and its release.

Le trou cylindrique 213 percé de part en part dans le corps moulé 202 est évasé ou rainuré dans le plan de la coupe d'une forme rectangulaire côté filtre, pour guider et faciliter le glissement du flexible 201. Le trou cylindrique 213 présente un chambrage 212, plus ou moins long, côté poignée 206. Le diamètre de ce chambrage 212 est plus petit que le diamètre extérieur de la poignée 206 (partie moletée). Le corps 202 comporte deux ailes 208, 209 permettant la création d'une forme cylindrique partielle 210 ayant pour axe et pour diamètre approximatif celui du filtre, afin d'en épouser la forme pour faciliter le serrage.The cylindrical hole 213 drilled right through in the molded body 202 is flared or grooved in the plane of the section of a rectangular shape on the filter side, to guide and facilitate the sliding of the hose 201. The cylindrical hole 213 has a recess 212 , more or less long, handle side 206. The diameter of this recess 212 is smaller than the outside diameter of the handle 206 (knurled part). The body 202 comprises two wings 208, 209 allowing the creation of a partial cylindrical shape 210 having for axis and for approximate diameter that of the filter, in order to follow the shape to facilitate tightening.

La poignée cylindrique 206 percée de part en part d'un trou taraudé, se visse sur la tige filetée 204 assurant sa traction et celle du flexible 201, qui peut serrer fortement le filtre encerclé. La poignée cylindrique 206 peut être moletée. La poignée cylindrique 206 comporte un épaulement 211 plus ou moins long, qui vient s'ajuster dans le chambrage 212, du type H7/g6. Un jeu 217 permet le contact plan entre la poignée 206 et le corps 202 à l'extrémité de celui-ci. La poignée 206 est centrée sur le corps 202.The cylindrical handle 206 pierced right through a tapped hole, is screwed onto the threaded rod 204 ensuring its traction and that of the hose 201, which can tighten the encircled filter strongly. The cylindrical handle 206 can be knurled. The cylindrical handle 206 has a more or less long shoulder 211, which fits into the recess 212, of the H7 / g6 type. A clearance 217 allows the plane contact between the handle 206 and the body 202 at the end of the latter. The handle 206 is centered on the body 202.

La poignée 206 et le corps 202, principalement de forme cylindrique et de même diamètre, sont bout à bout, coaxiaux et centrés par la penétration du diamètre épaulé 211 dans le chambrage 212. La poignée 206 peut tourner par rapport au corps 202 tout en restant centrée par rapport à celui-ci. La poignée 206 n'a qu'un degré de liberté par rapport au corps 202. à savoir une rotation d'axe colinéaire à l'axe du trou 213.The handle 206 and the body 202, mainly of cylindrical shape and of the same diameter, are end to end, coaxial and centered by the penetration of the shouldered diameter 211 in the recess 212. The handle 206 can rotate relative to the body 202 while remaining centered relative to it. The handle 206 has only one degree of freedom relative to the body 202. namely a rotation of an axis collinear with the axis of the hole 213.

Une rainure demi-torique 215 est pratiquée sur l'épaulement 211. Une goupille cylindrique 205 d'axe orthogonal à l'axe longitudinal de la poignée 206 empêche la pièce 206 de se séparer du corps 202 (Figure 23).A semi-toric groove 215 is formed on the shoulder 211. A cylindrical pin 205 with an axis orthogonal to the longitudinal axis of the handle 206 prevents the part 206 from separating from the body 202 (Figure 23).

Une autre solution peut être envisagée (Figure 22), en pratiquant une rainure circulaire de section triangulaire sur le diamètre épaulé 211 et en utilisant une vis sans tête à bout pointu 214 comme arrêt en translation de la poignée 206 par rapport au corps 202.Another solution can be envisaged (FIG. 22), by practicing a circular groove of triangular section on the shouldered diameter 211 and using a pointless headless screw 214 as a stop in translation of the handle 206 relative to the body 202.

D'autres solutions technologiques peuvent être envisagées pour assurer cet arrêt.Other technological solutions can be envisaged to ensure this stop.

La tige filetée 204 est fendue à son extrémité, côté flexible, dans un plan diamétral, d'une rainure d'environ 1 à 2 mm de largeur, sur une longueur de 8 à 15 mm, afin de permettre l'engagement des deux extrémités du flexible 201 et leur fixation, soit par un rivet 203, soit par une soudure ou par tout autre moyen économique et robuste.The threaded rod 204 is slotted at its end, flexible side, in a diametral plane, with a groove of approximately 1 to 2 mm in width, over a length of 8 to 15 mm, in order to allow the engagement of the two ends. of the hose 201 and their fixing, either by a rivet 203, or by a weld or by any other economical and robust means.

Un bouchon 207, vissé, forcé ou collé dans le trou taraudé de la pièce 206, obstrue l'extrémité opposée à la pièce 202 pour empêcher toute pénétration dans le dispositif et également pour l'esthétique et la sécurité de l'opérateur.A plug 207, screwed, forced or glued into the tapped hole of the part 206, obstructs the end opposite to the part 202 to prevent any penetration into the device and also for the aesthetics and the safety of the operator.

La tige filetée 204 reste, en toutes positions, à l'intérieur du dispositif. La longueur de celle-ci est égale à une fois son diamètre plus la longueur de la poignée 206, par exemple, et nettement inférieure à la longueur des pièces 202 et 206 placées bout à bout. La tige filetée 204 peut pénétrer dans le dispositif jusqu'à son contact avec le bouchon 207. Le taraudage de part en part de la poignée 206 favorise la course de la tige filetée 204. Plusieurs calibres de ce dispositif peuvent être proposés en fonction des diamètres de filtre et de l'espace moteur libre dans la zone du filtre.The threaded rod 204 remains, in all positions, inside the device. The length of the latter is equal to once its diameter plus the length of the handle 206, for example, and much less than the length of the parts 202 and 206 placed end to end. The threaded rod 204 can penetrate the device until it comes into contact with the plug 207. The tapping right through the handle 206 favors the stroke of the threaded rod 204. Several sizes of this device can be offered depending on the diameters filter and free engine space in the filter area.

Les longueurs de la poignée 206, de l'épaulement 211, du chambrage 212, du corps moulé 202, de la tige filetée 204, peuvent varier avec l'avantage d'assurer une plus ou moins grande course donc une meilleure adaptabilité aux différents diamètres de filtres couramment commercialisés.The lengths of the handle 206, of the shoulder 211, of the recess 212, of the molded body 202, of the threaded rod 204, can vary with the advantage of ensuring a greater or lesser stroke therefore a better adaptability to the different diameters of filters commonly sold.

Pour résumer l'utilisation : en tournant la poignée 206 (rotation suivant son axe), le flexible 201 lié à la tige filetée 204 se tend et vient serrer fortement le filtre. L'opérateur n'a plus qu'à pousser horizontalement sur la poignée 206.To summarize the use: by turning the handle 206 (rotation along its axis), the hose 201 linked to the threaded rod 204 tightens and tightens the filter strongly. The operator only has to push horizontally on the handle 206.

Caractéristiques de la poussée horizontale:

  • * Direction : orthogonale à l'axe du filtre
  • * Point d'application : environ le milieu de la poignée 206.
Characteristics of the horizontal thrust:
  • * Direction: orthogonal to the filter axis
  • * Application point: around the middle of handle 206.

Le dispositif selon l'invention est compact et esthétique, ne présente pas d'aspérité et d'angle vif risquant de blesser l'utilisateur, et peut s'adapter à tous les filtres à huile et à gazole, cylindriques, ovales ou de formes elliptiques quelconques.The device according to the invention is compact and aesthetic, does not have any roughness and sharp angle that could injure the user, and can be adapted to all oil and diesel filters, cylindrical, oval or shaped any elliptical.
