Description

La présente invention est relative aux dispositifs d'actionnement d'organes mobiles tels que les vitres des véhicules automobiles. Elle concerne plus particulièrement les dispositifs d'actionnement du type comprenant un tambour rotatif sur lequel s'enroule un élément souple travaillant en traction et en poussée.The present invention relates to devices for actuating movable members such as the windows of motor vehicles. It relates more particularly to actuation devices of the type comprising a rotary drum on which is wound a flexible element working in traction and in thrust.

Les dispositifs d'actionnement connus utilisent comme élément souple des câbles d'acier. Pour empêcher la décohésion du câble lors du fonctionnement en poussée, et également pour diminuer les frottements entre ce câble et le carter du tambour et/ou entre ce câble et son canal de guidage dans les mêmes conditions, il est nécessaire d'entourer le câble d'une gaine de matière plastique.Known actuating devices use steel cables as a flexible element. To prevent decohesion of the cable during pushing operation, and also to reduce friction between this cable and the drum casing and / or between this cable and its guide channel under the same conditions, it is necessary to surround the cable a plastic sheath.

Ceci conduit à un diamètre relativement grand du câble gainé, de l'ordre de 6 mm pour les lève-glace d'automobiles; il en résulte un encombrement radial et axial relativement important du tambour, dû non seulement à la section du câble, mais également à la courbure limitée qu'un tel câble peut prendre.This leads to a relatively large diameter of the sheathed cable, of the order of 6 mm for automobile window regulators; this results in a relatively large radial and axial size of the drum, due not only to the section of the cable, but also to the limited curvature that such a cable can take.

Pour diminuer cet encombrement, on peut penser à diminuer la section du câble d'acier. Cependant, il devient alors difficile d'obtenir facilement l'accrochage fiable sur le câble gainé de l'organe mobile, qui est généralement un curseur_guidé par un rail.To reduce this size, we can think of reducing the section of the steel cable. However, it then becomes difficult to easily obtain reliable attachment to the sheathed cable of the movable member, which is generally a cursor_guided by a rail.

L'invention a pour but de fournir un dispositif d'actionnement permettant de diminuer nettement l'encombrement du tambour ainsi que le poids de l'ensemble du dispositif sans gêner l'accrochage de l'organe mobile sur l'élément souple..The object of the invention is to provide an actuating device making it possible to significantly reduce the size of the drum as well as the weight of the entire device without hampering the attachment of the movable member to the flexible element.

A cet effet, l'invention a pour objet un dispositif d'actionnement du type précité, caractérisé en ce que l'élément souple est un ruban en matière plastique à section rectangulaire pleine constante.To this end, the invention relates to an actuating device of the aforementioned type, characterized in that the flexible element is a plastic tape with a constant full rectangular section.

En effet, la Demanderesse a constaté que de façon surprenante, moyennant un choix convenable de la matière plastique du ruban, celui-ci peut posséder des propriétés mécaniques sensiblement équivalentes à celles d'un câble d'acier avec une grande dimension égale au diamètre de ce câble.Indeed, the Applicant has found that, surprisingly, by means of a suitable choice of the plastic material of the ribbon, the latter can have mechanical properties substantially equivalent to those of a steel cable with a large dimension equal to the diameter of this cable.

Le dispositif d'actionnement peut notamment être du type à tambour en forme de disque présentant sur une face une gorge en forme générale de spirale, comme décrit dans le brevet FR 80 22013 de la Demanderesse et dans son certificat d'addition FR 81 08874. Dans ce cas, l'encombrement est particulièrement réduit si le ruban est reçu dans une gorge du tambour de section conjuguée, la grande dimension de cette gorge étant sa dimension axiale.The actuating device can in particular be of the disc-shaped drum type having on one side a groove in the general shape of a spiral, as described in patent FR 80 22013 of the Applicant and in its certificate of addition FR 81 08874. In this case, the space requirement is particularly reduced if the ribbon is received in a groove of the drum of conjugate section, the large dimension of this groove being its axial dimension.

Le guidage parfait et sans jeu du ruban n'impose de retenir ce dernier dans la gorge qu'au voisinage du point ou il sort de cette gorge, c'est-à-dire sur un secteur angulaire limité. On peut ainsi obtenir un gain de poids supplémentaire lorsque le carter est muni d'un capot largement ajouré de retenue du ruban dans la gorge, les ouvertures du capot étant éventuellement pourvues d'un cache en matière plastique.The perfect guiding and without play of the tape requires to retain the latter in the groove only in the vicinity of the point where it leaves this groove, that is to say over a limited angular sector. It is thus possible to obtain an additional weight gain when the casing is provided with a largely perforated cover for retaining the ribbon in the groove, the openings of the cover possibly being provided with a plastic cover.

Par ailleurs, les contraintes que subit l'élément souple sont d'une part les contraintes utiles de traction ou de compression, d'autre part des contraintes parasites dues à la courbure. Il faut donc dimensionner l'élément souple pour la somme de ces contraintes, ce qui surdiménsionne ses extrémités d'ancrage, qui sont rectilignes. Le dispositif de l'invention permet de mettre à profit ce surdimensionnement par le fait qu'à l'une au moins de ses extrémités, le ruban présente au moins un trou dans lequel est insérée une goupille transversale d'ancrage sur le tambour ou sur l'organe mobile, cette goupille étant reçue dans un évidement de ce tambour ou de cet organe. On obtient ainsi un mode de fixation spécifique de l'invention qui n'engendre pas de contraintes dans le ruban et qui est économique et fiable.Furthermore, the stresses to which the flexible element is subjected are on the one hand the useful tensile or compressive stresses, on the other hand parasitic stresses due to the curvature. It is therefore necessary to dimension the flexible element for the sum of these constraints, which oversizes its anchoring ends, which are rectilinear. The device of the invention makes it possible to take advantage of this oversizing by the fact that at at least one of its ends, the strip has at least one hole in which is inserted a transverse anchoring pin on the drum or on the movable member, this pin being received in a recess of this drum or this member. This gives a specific fixing method of the invention which does not generate constraints in the tape and which is economical and reliable.

L'invention a également pour objet un lève-glace d'automobile pourvu d'un dispositif d'actionnement tel que défini ci-dessus.The invention also relates to an automobile window regulator provided with an actuating device as defined above.

Le dispositif d'actionnement 1 représenté aux Fig. 1 à 4 est destiné à équiper un lève-glace de véhicule automobile. Il comprend un tambour 2 en matière plastique logé dans un carter métallique 3 et est destiné à déplacer dans les deux sens un curseur de bas de glace (non représenté) convenablement guïdé,au moyen d'un ruban souple 4 à section rectangulaire.The actuator 1 shown in Figs. 1 to 4 is intended to equip a window lift for a motor vehicle. It comprises a plastic drum 2 housed in a metal casing 3 and is intended to move in two directions a bottom ice slider (not shown) suitably guided, by means of a flexible tape 4 of rectangular section.

Le tambour 2 a la forme générale d'un disque annulaire plan dans une face 5 duquel est creusée une gorge 6 de section complémentaire de celle du ruban 4, avec sa grande dimension orientée axialement. Cette gorge présente la forme générale de spirale d'encombrement radial réduit décrite dans le brevet FR 80 22013 précité.The drum 2 has the general shape of a flat annular disc in one face 5 of which is hollowed out a groove 6 of section complementary to that of the ribbon 4, with its large dimension oriented axially. This groove has the general shape of a spiral of reduced radial size described in the aforementioned patent FR 80 22013.

La périphérie intérieure du tambour 2 présente, du côté de la face 5, une denture intérieure 7. A l'intersection de la périphérie extérieure de la face 8 opposée et de la surface cylindrique extérieure 9 du tambour est ménagée une piste de roulement 10 à section en quart de cercle.The inner periphery of the drum 2 has, on the side of the face 5, an internal toothing 7. At the intersection of the outer periphery of the opposite face 8 and the outer cylindrical surface 9 of the drum is provided a rolling track 10 to quarter circle section.

Le carter 3 est constitué par une cuvette 11 fermée par un capot serti 12. La cuvette 11 reçoit le tambour, avec interposition de billes 13, intercalées avec les organes séparateurs (non représentés), entre son angle arrondi 15 et la piste 10. Les deux contacts de chaque bille 13 sont inclinés à à peu près 45° sur l'axe X-X du tambour, de sorte que le roulement à billes ainsi constitué est à la fois un roulement de butée et un roulement de centrage du tambour dans son carter.The casing 3 consists of a bowl 11 closed by a crimped cover 12. The bowl 11 receives the drum, with the interposition of balls 13, interposed with the separating members (not shown), between its rounded angle 15 and the track 10. The two contacts of each ball 13 are inclined at approximately 45 ° on the axis XX of the drum, so that the ball bearing thus formed is both a thrust bearing and a centering bearing for the drum in its casing.

Le capot 12 présente en un point de son pourtour une saillie 16 ouverte circonférentiellement dans le sens de sortie du ruban 4. Cette saillie s'étend radialement sur tout l'intervalle occupé par la gorge 6, débouche à son origine dans le plan du capot, sur cette gorge, et se rétrécit progressivement en formant un appendice tangentiel 19 du capot 12.The cover 12 has, at a point on its periphery, a projection 16 open circumferentially in the direction of exit of the ribbon 4. This projection extends radially over the entire interval occupied by the groove 6, opens at its origin in the plane of the cover. , on this groove, and gradually narrows, forming a tangential appendage 19 of the cover 12.

La cuvette 11 comporte un autre appendice tangentiel 20 en regard de l'appendice 19. Ces deux appendices se terminent par deux mâchoires moletées 21, 22. Celles-ci, serties l'une sur l'autre (Fig. 4),enserrent et bloquent fermement un tube de guidage souple 23, en matière plastique, qui peut en particulier, comme représenté, être constitué par la partie d'extrémité du canal de guidage du câble jusqu'au curseur de bas de glace. Le tube 23 est libre entre les mâchoires 21, 22 et la gorge 6 et est contenu à l'intérieur de la saillie 16; il se termine par une tranche biseautée 24 située à peu près dans le plan général du capot 12 et donc perpendiculaire à l'axe X-X du tambour 2 et voisine de la face 5 de celui-ci.The bowl 11 has another tangential appendage 20 opposite the appendage 19. These two appendages end in two knurled jaws 21, 22. These, crimped one on the other (Fig. 4), enclose and firmly block a flexible guide tube 23, in plastic material, which may in particular, as shown, consist of the end part of the cable guide channel up to the bottom window cursor. The tube 23 is free between the jaws 21, 22 and the groove 6 and is contained inside the projection 16; it ends with a bevelled edge 24 located roughly in the general plane of the cover 12 and therefore perpendicular to the axis XX of the drum 2 and close to the face 5 thereof.

L'extrémité du tube 23 est enfilée à force sur un élément de renforcement tubulaire rigide 25 qui présente comme le tube 23 une section intérieure rectangulaire conjuguée de celle du ruban 4. L'extrémité libre de l'élément 25 forme un bec 26 qui pénètre dans la gorge 6.The end of the tube 23 is forcibly threaded onto a rigid tubular reinforcing element 25 which, like the tube 23, has a rectangular internal section combined with that of the ribbon 4. The free end of the element 25 forms a beak 26 which penetrates in the throat 6.

Le ruban 4 est plein, à section rectangulaire constante, à faces lisses. Il est constitué d'une matière plastique à hautes propriétés mécaniques, qui peut en particulier être un polyester étiré . Un exemple d'un tel. ruban est le ruban vendu, dans le commerce par la Société du Pont de Nemours sous la dénomination "EPS tape DYMETROL", une section appropriée étant 6 x 1,8 mm. Ce ruban présente une résistance à la traction de 30 kg/mm2, avec une limite d'élasticité de 10 kg/mm2 .The ribbon 4 is full, of constant rectangular section, with smooth faces. It consists of a plastic material with high mechanical properties, which can in particular be a drawn polyester. An example of such. ribbon is the ribbon sold commercially by the Société du Pont de Nemours under the name "EPS tape DYMETROL", an appropriate section being 6 x 1.8 mm. This tape has a tensile strength of 30 kg / mm 2 , with an elastic limit of 10 kg / mm 2 .

Le ruban 4 est ancré par une extrémité, d'une manière qui sera précisée plus loin, à l'extrémité intérieure de la gorge 6. Il est inséré de chant dans celle-ci, dont il remplit exactement la section en affleurant la face 5 du tambour 2. Lorsqu'il est entièrement enroulé, il suit la gorge 6 jusqu'à un point voisin de l'extrémité extérieure de celle-ci et de l'entrée de la saillie 16, point où il commence à sortir de la gorge 6 sur chant pour pénétrer dans l'élément de renforcement 25 (Fig. 2). Comme on le voit à la Fig. 2, le capot 12 est bombé près de la saillie 16 pour permettre cette sortie du ruban 4.Puis le ruban 4 traverse le tube 23 et le canal de guidage qui prolonge ce dernier et est ancré à son autre extrémité au curseur de bas de glace.The ribbon 4 is anchored by one end, in a manner which will be specified later, to the interior end of the groove 6. It is inserted into the groove, of which it exactly fills the section by being flush with the face 5 of the drum 2. When it is fully wound, it follows the groove 6 to a point close to the outer end of the latter and the entrance to the projection 16, point where it begins to exit from the groove 6 on edge to penetrate the reinforcing element 25 (Fig. 2). As seen in Fig. 2, the cover 12 is curved near the projection 16 to allow this exit of the ribbon 4. Then the ribbon 4 passes through the tube 23 and the guide channel which extends the latter and is anchored at its other end to the bottom window cursor.

Lorsque le tambour est entraîné en rotation dans le sens de la flèche f (Fig. 1), le ruban 4 travaille en poussée. Il sort progressivement de la gorge 6 de la même façon que précédemment, l'extrémité renforcée du tube 23 suivant sans difficulté les variations de rayon du point de sortie du ruban en se déplaçant par flexion d'une extrémité radiale à l'autre de la saillie 16, guidée par le bec 26. Les billes 13 et la cuvette 11 d'une part, la face avant (en considérant la Fig. 1) de la saillie 16 et de son appendice 19 d'autre part, reprennent les efforts axiaux exercés par le ruban 4 lors de ce déroulement.When the drum is rotated in the direction of arrow f (Fig. 1), the ribbon 4 works in thrust. It gradually comes out of the groove 6 in the same way as above, the reinforced end of the tube 23 without difficulty following the variations in radius of the point of exit of the ribbon by moving by bending from one radial end to the other of the projection 16, guided by the spout 26. The balls 13 and the bowl 11 on the one hand, the front face (considering FIG. 1) of the projection 16 and its appendage 19 on the other hand, take up the axial forces exerted by the ribbon 4 during this course.

L'enroulement du ruban 4, correspondant à un travail en traction de celui-ci, s'opère de la même façon; le rôle des éléments 16, 23 et 25 est cependant moindre puisqu'aucun flambage du ruban n'est alors à craindre.The winding of the ribbon 4, corresponding to a work in traction of the latter, operates in the same way; the role of the elements 16, 23 and 25 is however less since no buckling of the ribbon is then to be feared.

Pour l'entraînement du tambour 3, l'arbre moteur 27 du dispositif 1 est guidé parallèlement à l'axe X-X par deux paliers 28, 29 prévus dans des bossages alignés de la cuvette 11 et du capot 12. L'arbre 27 porte un pignon 30 en prise avec la denture 7 du tambour, ainsi qu'un mécanisme connu 31 du type "auto-lock" qui est logé dans un bossage rapporté 32 du capot 12.L'arbre 27 fait saillie hors de ce bossage pour être relié à un dispositif d'actionnement non représenté.For driving the drum 3, the drive shaft 27 of the device 1 is guided parallel to the axis XX by two bearings 28, 29 provided in aligned bosses of the bowl 11 and of the cover 12. The shaft 27 carries a pinion 30 in engagement with the toothing 7 of the drum, as well as a known mechanism 31 of the "auto-lock" type which is housed in an attached boss 32 of the cover 12. The shaft 27 protrudes out of this boss to be connected to an actuator not shown.

Le ruban 4 a une section de 6 x 1,8 mm environ. Ses propriétés mécaniques le rendent apte à remplacer le câble d'actionnement gainé de 6 mm de diamètre utilisé dans le dispositif analogue antérieur décrit dans le certificat d'addition FR 81 08 874 précité, avec les avantages suivants:

  • - dimension radiale du dispositif réduite d'environ 30%;
  • - poids du dispositif réduit d'environ 50%;
  • - plus grande facilité de réalisation de la gorge du tambour, qui ne présente pas de contre-dépouille; et
  • pas de course morte lors de l'inversion du sens de manoeuvre.
The tape 4 has a section of approximately 6 x 1.8 mm. Its mechanical properties make it suitable for replacing the sheathed actuation cable 6 mm in diameter used in the previous analog device described in the above-mentioned addition certificate FR 81 08 874, with the following advantages:
  • - radial dimension of the device reduced by approximately 30%;
  • - weight of the device reduced by around 50%;
  • - Greater ease of making the groove of the drum, which has no undercut; and
  • no dead travel when reversing the direction of operation.

De plus, grâce à son très bon guidage, le ruban 4 travaillant en compression n'a tendance à flamber qu'à partir du moment où il commence à sortir de sa gorge. Par conséquent, sur près de trois quarts de tour, le capot 12 peut pratiquement être supprimé, ou du moins largement ajouré pour alléger encore le dispositif. Les ouvertures du capot peuvent alors être pourvues de caches en matière plastique très légers, pour la protection contre la poussière et autres impuretés.In addition, thanks to its very good guidance, the ribbon 4 working in compression does not tend to flame until the moment it begins to come out of its throat. Consequently, over almost three quarters of a turn, the cover 12 can practically be eliminated, or at least largely perforated to further lighten the device. The hood openings can then be fitted with very light plastic covers, to protect against dust and other impurities.

En variante (Fig. 5 à 8), pour éviter de décaler le ruban 4 sur chant lors de sa sortie, on peut utiliser un élément de renforcement 25A vrillé d'un quart de tour, comme illustré schématiquement aux Fig. 6 à 8.La grande dimension du tube 23 dans les mâchoires 21,22 est alors non plus parallèle mais perpendiculaire à l'axe X-X.Conne représenté à la Fig. 5, on peut prévoir dans le carter 3, entre l'élément 25A et l'appendice 20, un élément supplémentaire 33 de guidage du tube 23.As a variant (FIGS. 5 to 8), to avoid shifting the strip 4 on edge when it leaves, it is possible to use a reinforcing element 25A twisted by a quarter turn, as illustrated diagrammatically in FIGS. 6 to 8. The large dimension of the tube 23 in the jaws 21, 22 is then no longer parallel but perpendicular to the axis X-X. As shown in FIG. 5, an additional element 33 for guiding the tube 23 can be provided in the casing 3, between the element 25A and the appendix 20.

Les Fig. 9 et 10 illustrent le mode d'ancrage du ruban 4 dans l'extrémité intérieure de la gorge 6, l'ancrage de ce ruban sur le curseur pouvant être réalisé de la même façon.Figs. 9 and 10 illustrate the method of anchoring the ribbon 4 in the inner end of the groove 6, it is possible to anchor this ribbon on the slider in the same way.

L'extrémité du ruban est rectiligne et présente trois trous 34 proches les uns des autres, situés dans un élargissement local 35 de la gorge 6 qui ne s'étend que sur une partie de la profondeur de celle-ci à partir de la face 5 du tambour. Un peigne 36 à trois dents 37 complémentaires des trous 34 est engagé dans ces trous et est inséré axialement dans l'élargissement 35, dont il épouse la forme. Il est clair que cet ancrage ne crée en lui-même aucune contrainte dans le ruban.The end of the strip is straight and has three holes 34 close to each other, located in a local enlargement 35 of the groove 6 which extends only over part of the depth thereof from the face 5 of drum. A comb 36 with three teeth 37 complementary to the holes 34 is engaged in these holes and is inserted axially in the enlargement 35, the shape of which it follows. It is clear that this anchoring does not in itself create any constraint in the ribbon.

La dimension des trous 34 est telle que la section restante suffise pour supporter les contraintes de poussée et de traction; ceci est rendu possible par le fait que l'extrémité du ruban ainsi ancrée est rectiligne et n'est donc pas soumise à des contraintes supplémentaires dues à la courbure.The size of the holes 34 is such that the remaining section is sufficient to withstand the stresses of thrust and traction; this is made possible by the fact that the end of the ribbon thus anchored is straight and is therefore not subject to additional stresses due to the curvature.

En variante, le ruban 4 peut être armé par un ou plusieurs fils métalliques longitudinaux.As a variant, the ribbon 4 can be armed with one or more longitudinal metal wires.
