Description

Ensemble de connexion d'un système d'essuyage. Connection assembly for a wiping system.
Le domaine de la présente invention est celui des systèmes d’essuyage destinés aux véhicules automobiles. Plus particulièrement, le domaine de la présente invention est celui des adaptateurs ou des ensembles de connexion disposés entre un bras d’essuie- glace et un balai d’essuyage de tels systèmes d’essuyage. The field of the present invention is that of wiping systems intended for motor vehicles. More particularly, the field of the present invention is that of adapters or connection assemblies arranged between a windshield wiper arm and a wiper blade of such wiping systems.
Les véhicules automobiles sont couramment équipés de systèmes d’essuyage destinés à nettoyer leurs surfaces vitrées, et notamment leur pare-brise. De tels systèmes d’essuyage comprennent au moins un bras d’essuie-glace et un balai d’essuyage entrainé par le bras d’essuie-glace. Le bras d’essuie-glace est relié à un moteur électrique du véhicule et le balai d’essuyage comprend au moins une lame d’essuyage adaptée pour venir au contact de la surface vitrée à essuyer. Afin de pouvoir entrainer le balai d’essuyage, un adaptateur est agencé entre ce balai d’essuyage et le bras d’essuie-glace. Plus particulièrement, l’adaptateur est agencé entre le bras d’essuie- glace et un connecteur relié au balai d’essuyage. L’adaptateur est alors solidaire du bras d’essuie-glace et plus particulièrement d’une extrémité libre du bras d’essuie- glace au moyen d’un dispositif de verrouillage, une telle coopération étant amovible de telle sorte qu’elle permet de changer le balai d’essuyage lorsque celui-ci est usé.Motor vehicles are commonly equipped with wiping systems intended to clean their glass surfaces, and in particular their windshields. Such wiping systems include at least one wiper arm and a wiper blade driven by the wiper arm. The windshield wiper arm is connected to an electric motor of the vehicle and the wiper blade comprises at least one wiping blade adapted to come into contact with the glass surface to be wiped. In order to be able to drive the wiper blade, an adapter is arranged between this wiper blade and the wiper arm. More particularly, the adapter is arranged between the windshield wiper arm and a connector connected to the wiper blade. The adapter is then secured to the windshield wiper arm and more particularly to a free end of the windshield wiper arm by means of a locking device, such cooperation being removable such that it allows change the wiper blade when it is worn.
Habituellement, la liaison entre l’adaptateur et le connecteur s’effectue au moyen d’un arbre de rotation reliant ledit connecteur audit adaptateur. Plus particulièrement, l’arbre de rotation est inséré dans un palier de rotation et un alésage respectivement réalisés dans l’adaptateur et le connecteur afin de lier en rotation ces derniers. Afin de faciliter l’opération de rotation, il est connu que la surface externe dudit arbre de rotation soit lisse. Usually, the connection between the adapter and the connector is made by means of a rotation shaft connecting said connector to said adapter. More particularly, the rotation shaft is inserted into a rotation bearing and a bore respectively made in the adapter and the connector in order to rotate the latter. In order to facilitate the rotation operation, it is known that the external surface of said rotation shaft is smooth.
Un problème d’une telle liaison entre l’adaptateur et le connecteur au moyen de l’arbre de rotation à surface lisse réside entre autres dans le maintien transversal dudit arbre de rotation dans le palier de rotation et l’alésage de l’adaptateur et du connecteur. En effet, la surface lisse de l’arbre de rotation offre peu d’adhérence audit arbre de rotation qui peut glisser en dehors du palier de rotation et de l’alésage le recevant. L’échappée de l’arbre de rotation en dehors de son logement entraine alors une séparation de l’adaptateur et du connecteur. Une telle séparation de l’adaptateur et du connecteur génère alors des problèmes de sécurité, à la fois pour le conducteur et pour les autres usagers de la route. Le but de la présente invention est donc de remédier aux problèmes susmentionnés en proposant une liaison entre l’adaptateur et le connecteur qui soit fiable. Autrement dit, l’invention propose des solutions afin d’améliorer le maintien de l’arbre de rotation dans le palier de rotation et l’alésage de l’adaptateur et/ ou du connecteur, limitant ainsi les risques de séparation de ceux-ci. A problem of such a connection between the adapter and the connector by means of the rotation shaft with a smooth surface lies, among other things, in the transverse retention of said rotation shaft in the rotation bearing and the bore of the adapter and of the connector. Indeed, the smooth surface of the rotation shaft offers little adhesion to said rotation shaft which can slide outside the rotation bearing and the bore receiving it. The escape of the rotation shaft outside its housing then causes separation of the adapter and the connector. Such separation of the adapter and the connector then generates safety problems, both for the driver and for other road users. The aim of the present invention is therefore to remedy the aforementioned problems by providing a connection between the adapter and the connector which is reliable. In other words, the invention proposes solutions to improve the retention of the rotation shaft in the rotation bearing and the bore of the adapter and/or connector, thus limiting the risks of separation thereof. .
L’invention a ainsi pour principal objet un ensemble de connexion comprenant un adaptateur pour la fixation d’un balai d’essuyage à un bras d’un système d’essuyage et un arbre de rotation configuré pour relier un connecteur à l’adaptateur, l’adaptateur comprenant au moins une paroi supérieure et au moins une paroi interne qui participent à délimiter une zone de réception du connecteur, la zone de réception du connecteur étant configurée pour recevoir un organe de fixation du connecteur, l’au moins une paroi interne de la zone de réception comprenant au moins un palier de rotation dans lequel se loge au moins en partie l’arbre de rotation, l’adaptateur comprenant au moins un organe de butée configuré pour bloquer l’arbre de rotation en translation dans le palier de rotation selon un premier sens le long d’une direction et comprend un volume de réception du bras configuré pour qu’à l’état monté le bras bloque l’arbre de rotation en translation dans le palier de rotation selon un deuxième sens le long de la direction, opposée au premier sens. The main object of the invention is therefore a connection assembly comprising an adapter for fixing a wiping blade to an arm of a wiping system and a rotation shaft configured to connect a connector to the adapter, the adapter comprising at least one upper wall and at least one internal wall which help to delimit a connector reception zone, the connector reception zone being configured to receive a connector fixing member, the at least one internal wall of the reception zone comprising at least one rotation bearing in which the rotation shaft is housed at least in part, the adapter comprising at least one stop member configured to block the rotation shaft in translation in the bearing rotation in a first direction along a direction and comprises a receiving volume of the arm configured so that in the mounted state the arm blocks the rotation shaft in translation in the rotation bearing in a second direction along the direction, opposite to the first direction.
Le balai d’essuyage et le bras font partie d’un système d’essuyage d’un véhicule destiné à nettoyer au moins en partie une surface vitrée dudit véhicule. Le système d’essuyage comprend alors le bras entrainé en rotation par un moteur électrique du véhicule et assurant le mouvement de rotation du balai d’essuyage, auquel il est solidaire via l’ensemble de connexion et le connecteur, contre la surface vitrée afin que la lame portée par le balai d’essuyage débarrasse ladite surface vitrée des gouttes de pluie et/ou de débris solides, déposés sur cette dernière. The wiper blade and the arm are part of a vehicle wiping system intended to clean at least partially a glass surface of said vehicle. The wiping system then comprises the arm rotated by an electric motor of the vehicle and ensuring the rotational movement of the wiping blade, to which it is secured via the connection assembly and the connector, against the glass surface so that the blade carried by the wiping blade rids said glazed surface of raindrops and/or solid debris deposited on the latter.
L’adaptateur comprend par ailleurs un dispositif de verrouillage qui participe à la fixation de l’adaptateur sur le bras, en bloquant la position de l’adaptateur sur ledit bras. The adapter also comprises a locking device which participates in fixing the adapter on the arm, by blocking the position of the adapter on said arm.
On comprend que l’arbre de rotation relie l’adaptateur avec le connecteur qui se loge en partie dans la zone de réception de l’adaptateur, ledit arbre de rotation traversant l’au moins un palier de rotation de l’adaptateur et un alésage traversant du connecteur. Une telle coopération entre l’adaptateur et le connecteur au moyen de l’arbre de rotation autorise la rotation dudit adaptateur par rapport au connecteur autour d’un axe de rotation passant par l’arbre de rotation. On tire alors avantage de l’organe de butée en ce qu’il permet de bloquer l’arbre de rotation suivant le premier sens le long de la direction qui est parallèle à un axe de rotation, dans l’au moins un palier de rotation de l’adaptateur. Ainsi, on diminue les risques de voir l’arbre de rotation sortir en dehors du au moins un palier de rotation de l’adaptateur, réduisant ainsi les risques de séparation de l’adaptateur par rapport au connecteur. It is understood that the rotation shaft connects the adapter with the connector which is housed partly in the receiving zone of the adapter, said rotation shaft passing through at least one rotation bearing of the adapter and a bore through the connector. Such cooperation between the adapter and the connector by means of the rotation shaft authorizes the rotation of said adapter relative to the connector around an axis of rotation passing through the rotation shaft. We then take advantage of the stop member in that it makes it possible to block the rotation shaft in the first direction along the direction which is parallel to an axis of rotation, in the at least one rotation bearing. of the adapter. Thus, the risks of the rotation shaft emerging outside of at least one rotation bearing of the adapter are reduced, thus reducing the risks of the adapter separating from the connector.
On tire également avantage du volume de réception du bras, en ce qu’à l’état monté du bras au sein dudit volume de réception, le bras bloque l’arbre de rotation suivant le deuxième sens le long de ladite direction et vient sécuriser l’arbre de rotation au sein du au moins un palier de rotation de l’adaptateur. We also take advantage of the receiving volume of the arm, in that in the mounted state of the arm within said receiving volume, the arm blocks the rotation shaft in the second direction along said direction and secures the rotation shaft within the at least one rotation bearing of the adapter.
Ainsi, l’arbre de rotation est encadré à la fois par l’organe de butée et par le bras, de sorte qu’il ne peut pas sortir en dehors du au moins un palier de rotation de l’adaptateur, éliminant ainsi tous risques de séparation de l’adaptateur par rapport au connecteur. Thus, the rotation shaft is framed both by the stop member and by the arm, so that it cannot exit outside of at least one rotation bearing of the adapter, thus eliminating all risks separation of the adapter from the connector.
Selon une caractéristique de l’invention, l’adaptateur est configuré pour être monté rotatif sur le connecteur du balai d’essuyage autour d’un axe de rotation transversal à une direction longitudinale de l’adaptateur. According to one characteristic of the invention, the adapter is configured to be rotatably mounted on the connector of the wiper blade around an axis of rotation transverse to a longitudinal direction of the adapter.
On comprend que l’adaptateur s’étend principalement suivant la direction longitudinale et que l’axe de rotation est sécant de cette direction longitudinale. It is understood that the adapter extends mainly in the longitudinal direction and that the axis of rotation is secant from this longitudinal direction.
Selon un exemple de l’invention, la direction longitudinale et l’axe de rotation sont perpendiculaires l’un de l’autre. La direction des premier et deuxième sens de blocage en translation de l’arbre de rotation dans le palier de rotation est parallèle voire confondue avec l’axe de rotation. According to an example of the invention, the longitudinal direction and the axis of rotation are perpendicular to each other. The direction of the first and second directions of blocking in translation of the rotation shaft in the rotation bearing is parallel or even coincident with the axis of rotation.
Selon une caractéristique de l’invention, l’au moins une paroi interne de l’adaptateur est une première paroi interne et l’adaptateur comprend une deuxième paroi interne qui participe à délimiter la zone de réception, les parois internes étant parallèles l’une de l’autre selon la direction longitudinale de l’adaptateur, chacune des parois internes comprenant un palier de rotation dans lequel loge au moins en partie l’arbre de rotation. According to one characteristic of the invention, the at least one internal wall of the adapter is a first internal wall and the adapter comprises a second internal wall which contributes to delimiting the reception zone, the internal walls being parallel to one another. on the other in the longitudinal direction of the adapter, each of the internal walls comprising a rotation bearing in which the rotation shaft is housed at least in part.
Selon une caractéristique de l’invention, l’adaptateur comprend au moins une paroi latérale qui participe à délimiter un volume interne de l’adaptateur qui comprend la zone de réception, l’organe de butée faisant saillie depuis la paroi latérale de l’adaptateur. According to one characteristic of the invention, the adapter comprises at least one side wall which contributes to delimiting an internal volume of the adapter which comprises the reception zone, the stop member projecting from the side wall of the adapter.
Selon une caractéristique de l’invention, le volume de réception du bras comprend au moins un conduit de guidage destiné à recevoir le bras et qui s’étend au moins en partie dans le volume interne de l’adaptateur. According to one characteristic of the invention, the receiving volume of the arm comprises at least one guide conduit intended to receive the arm and which extends at least partly into the internal volume of the adapter.
Selon une caractéristique de l’invention, le volume de réception du bras est décalé latéralement par rapport à la zone de réception du connecteur. According to one characteristic of the invention, the receiving volume of the arm is offset laterally relative to the receiving area of the connector.
Selon une caractéristique de l’invention, la première paroi interne s’étend entre la deuxième paroi interne et la paroi latérale, l’organe de butée s’étendant à une distance transversale de la première paroi interne. According to one characteristic of the invention, the first internal wall extends between the second internal wall and the side wall, the stop member extending at a transverse distance from the first internal wall.
La distance transversale est prise le long d’une direction transversale de l’adaptateur, perpendiculaire de la direction longitudinale, entre une surface de contact de l’organe de butée et la première paroi interne, le long de l’axe de rotation, ladite distance transversale étant comprise entre o et 7,7mm. De préférence, la distance transversale est non nulle. Préférentiellement, la distance transversale est comprise entre 3,5mm avec une tolérance de +/- 0,1mm et 3,7mm avec une tolérance de +/- 0,1mm. The transverse distance is taken along a transverse direction of the adapter, perpendicular to the longitudinal direction, between a contact surface of the stop member and the first internal wall, along the axis of rotation, said transverse distance being between o and 7.7mm. Preferably, the transverse distance is non-zero. Preferably, the transverse distance is between 3.5mm with a tolerance of +/- 0.1mm and 3.7mm with a tolerance of +/- 0.1mm.
Selon une caractéristique de l’invention, un centre de l’organe de butée est aligné sur l’axe de rotation. According to one characteristic of the invention, a center of the stop member is aligned with the axis of rotation.
On permet ainsi un meilleur centrage de l’organe de butée par rapport à l’arbre de rotation destiné à se loger dans les paliers de rotation, et ainsi un meilleur appui dudit arbre de rotation sur l’organe de butée. This allows better centering of the stop member relative to the rotation shaft intended to be housed in the rotation bearings, and thus better support of said rotation shaft on the stop member.
Selon une caractéristique de l’invention, l’organe de butée est formé par au moins deux nervures distinctes l’une de l’autre. According to one characteristic of the invention, the stop member is formed by at least two ribs distinct from each other.
Selon une caractéristique de l’invention, la paroi latérale est une première paroi latérale, l’adaptateur comprenant une deuxième paroi latérale qui participe à délimiter le volume interne, la paroi supérieure étant interposée entre les parois latérales, la deuxième paroi latérale comprenant un dégagement disposé en regard des paliers de rotation. According to one characteristic of the invention, the side wall is a first side wall, the adapter comprising a second side wall which contributes to delimiting the internal volume, the upper wall being interposed between the side walls, the second side wall comprising a clearance arranged opposite the rotation bearings.
Le dégagement permet de faciliter l’insertion de l’arbre de rotation dans les paliers de rotation des parois internes de l’adaptateur, ledit arbre de rotation étant inséré dans les paliers de rotation par un mouvement de translation suivant la direction transversale de l’adaptateur. Selon une caractéristique de l’invention, le dégagement présente une forme semi- circulaire dont un centre est aligné sur l’axe de rotation. The clearance makes it possible to facilitate the insertion of the rotation shaft into the rotation bearings of the internal walls of the adapter, said rotation shaft being inserted into the rotation bearings by a translation movement following the transverse direction of the adapter. According to one characteristic of the invention, the clearance has a semi-circular shape, a center of which is aligned with the axis of rotation.
Selon une caractéristique de l’invention, l’adaptateur comprend au moins un dispositif de verrouillage monté basculant sur la paroi supérieure autour d’un axe de basculement parallèle à l’axe longitudinal de l’adaptateur et destiné à solidariser longitudinalement l’adaptateur par rapport au bras, au moyen d’un organe de blocage dudit dispositif de verrouillage. According to one characteristic of the invention, the adapter comprises at least one locking device mounted tilting on the upper wall around a tilting axis parallel to the longitudinal axis of the adapter and intended to secure the adapter longitudinally by relative to the arm, by means of a blocking member of said locking device.
L’invention porte également sur un dispositif de connexion pour un balai d’essuyage comprenant au moins un connecteur solidaire du balai d’essuyage et un ensemble de connexion selon l’une quelconque des caractéristiques précédentes et destiné à être solidaire d’un bras d’un système d’essuyage, le connecteur comprenant au moins un organe de fixation logé dans la zone de réception de l’adaptateur, l’organe de fixation comprenant un alésage traversant aligné sur un axe de rotation de l’adaptateur par rapport au connecteur et l’adaptateur étant monté rotatif sur le connecteur autour de l’axe de rotation au moyen au moins de l’arbre de rotation qui s’étend dans le palier de rotation et dans l’alésage traversant. The invention also relates to a connection device for a wiper blade comprising at least one connector secured to the wiper blade and a connection assembly according to any one of the preceding characteristics and intended to be secured to an arm of the wiper blade. a wiping system, the connector comprising at least one fixing member housed in the receiving zone of the adapter, the fixing member comprising a through bore aligned with an axis of rotation of the adapter relative to the connector and the adapter being rotatably mounted on the connector about the axis of rotation by means of at least the rotation shaft which extends into the rotation bearing and into the through bore.
Selon une caractéristique de l’invention, l’arbre de rotation s’étend le long d’une direction d’allongement principal selon une première dimension, la première dimension étant au moins égale à une deuxième dimension prise entre le palier de rotation de la deuxième paroi interne et une surface de contact de l’organe de butée. On garantit ainsi que l’arbre de rotation est en prise dans les deux palier de rotation de l’adaptateur quand il vient buter contre l’organe de butée. According to one characteristic of the invention, the rotation shaft extends along a direction of main elongation along a first dimension, the first dimension being at least equal to a second dimension taken between the rotation bearing of the second internal wall and a contact surface of the stop member. This ensures that the rotation shaft is engaged in the two rotation bearings of the adapter when it abuts against the stop member.
L’invention a également pour objet un balai d’essuyage comprenant au moins un dispositif de connexion selon les caractéristiques précédentes. The invention also relates to a wiper blade comprising at least one connection device according to the preceding characteristics.
L’invention protège également un système d’essuyage comprenant au moins un bras et un balai d’essuyage selon la caractéristique précédente, le bras comprenant au moins une tige se logeant dans le volume de réception de l’adaptateur. The invention also protects a wiping system comprising at least one arm and a wiping blade according to the preceding characteristic, the arm comprising at least one rod housed in the receiving volume of the adapter.
Selon une caractéristique de l’invention, au moins une extrémité de la tige prend une forme complémentaire au volume de réception de l’adaptateur, la tige présentant une encoche coopérant avec le dispositif de verrouillage de l’adaptateur pour bloquer longitudinalement l’adaptateur par rapport à la tige. According to one characteristic of the invention, at least one end of the rod takes a shape complementary to the receiving volume of the adapter, the rod having a notch cooperating with the locking device of the adapter to block the adapter longitudinally by relation to the stem.
Selon une caractéristique de l’invention, la tige du bras s’étend au moins en partie en regard du palier de rotation de la paroi interne de l’adaptateur et de telle sorte qu’au moins une portion de la tige forme une zone de butée à l’égard de l’arbre de rotation. Selon cette configuration, on sécurise l’arbre de rotation qui, dans le premier sens le long de ladite direction, est limité dans son déplacement par l’organe de butée, et dans le deuxième sens le long de ladite direction, est limité dans son déplacement par la tige du bras. According to one characteristic of the invention, the rod of the arm extends at least partly in facing the rotation bearing of the internal wall of the adapter and such that at least one portion of the rod forms an abutment zone with respect to the rotation shaft. According to this configuration, the rotation shaft is secured which, in the first direction along said direction, is limited in its movement by the stop member, and in the second direction along said direction, is limited in its movement. movement by the arm rod.
Selon une caractéristique de l’invention, une première distance prise entre la zone de butée de la tige et le palier de rotation de la deuxième paroi interne est strictement inférieure à la distance transversale prise entre l’organe de butée et la première paroi interne. According to a characteristic of the invention, a first distance taken between the abutment zone of the rod and the rotation bearing of the second internal wall is strictly less than the transverse distance taken between the abutment member and the first internal wall.

Sur les figures, les éléments communs à plusieurs figures conservent la même référence. Dans la description détaillée qui va suivre, les dénominations « longitudinale », « transversale » et « verticale » se réfèrent à l’orientation d’un système d’essuyage et d’un adaptateur de l’ensemble de connexion selon l’invention. Une direction longitudinale correspond à une direction principale d’allongement d’un adaptateur de l’ensemble de connexion selon l’invention, cette direction longitudinale étant parallèle à un axe longitudinal L d’un trièdre L, V, T illustré sur les figures. Une direction transversale est parallèle à un axe transversal T du repère L, V, T et cet axe transversal T est perpendiculaire à l’axe longitudinal L. Enfin, une direction verticale correspond à une direction parallèle à un axe vertical V du repère L, V, T, cet axe vertical V étant perpendiculaire à l’axe longitudinal L et l’axe transversal T. In the figures, elements common to several figures retain the same reference. In the detailed description which follows, the terms “longitudinal”, “transverse” and “vertical” refer to the orientation of a wiping system and an adapter of the connection assembly according to the invention. A longitudinal direction corresponds to a main direction of elongation of an adapter of the connection assembly according to the invention, this longitudinal direction being parallel to a longitudinal axis L of a trihedron L, V, T illustrated in the figures. A transverse direction is parallel to a transverse axis T of the reference L, V, T and this transverse axis T is perpendicular to the longitudinal axis L. Finally, a vertical direction corresponds to a direction parallel to a vertical axis V of the reference L, V, T, this vertical axis V being perpendicular to the longitudinal axis L and the transverse axis T.
La figure i illustre un système d’essuyage i configuré pour assurer le nettoyage d’une surface vitrée d’un véhicule, par exemple un parebrise, de manière à améliorer la visibilité qu’a un conducteur de la route située devant le véhicule, par exemple par temps de pluie ou encore pour débarrasser ladite surface vitrée de débris solides accrochés à cette dernière. Le système d’essuyage i s’étend principalement le long de la direction longitudinale L, et comprend au moins un bras 2 d’essuyage portant à une extrémité un balai d’essuyage 4 et étant reliée à une autre extrémité opposée selon la direction longitudinale L au véhicule. Figure i illustrates a wiping system i configured to ensure the cleaning of a glass surface of a vehicle, for example a windshield, so as to improve the visibility that a driver has of the road located in front of the vehicle, by for example in rainy weather or to rid said glazed surface of solid debris clinging to it. The wiping system i extends mainly along the longitudinal direction L, and comprises at least one wiping arm 2 carrying at one end a wiping blade 4 and being connected to another opposite end in the longitudinal direction L to the vehicle.
Le bras 2 et le balai d’essuyage 4 s’étendent tous deux principalement suivant la direction longitudinale L du système d’essuyage 1. Le bras 2 comprend plus précisément un corps de liaison destiné à rendre solidaire le bras 2 du véhicule et une tige 6 s’étendant depuis le corps de liaison jusqu’à une extrémité du bras 2. On comprend par « tige » un élément plein et s’allongeant le long de la direction longitudinale L. La tige 6 présente ici une section rectangulaire, vue dans un plan perpendiculaire à la direction longitudinale L. Cependant, une tige présentant une section discoïde, triangulaire ou autre ne sortirait pas pour autant du cadre de l’invention. The arm 2 and the wiper blade 4 both extend mainly in the longitudinal direction L of the wiper system 1. The arm 2 comprises more precisely a connecting body intended to secure the arm 2 of the vehicle and a rod 6 extending from the connecting body to one end of the arm 2. By “rod” we understand a solid element and extending along the longitudinal direction L. The rod 6 here has a rectangular section, seen in a plane perpendicular to the longitudinal direction L. However, a rod having a discoid, triangular or other section would not therefore go beyond the scope of the invention.
De plus, le balai d’essuyage 4 est notamment adapté pour être entrainé en rotation par le bras 2 contre la surface vitrée du véhicule, le bras 2 étant lui -même entrainé en rotation par un moteur, non visible, par exemple un moteur électrique porté par le véhicule. In addition, the wiper blade 4 is particularly adapted to be rotated by the arm 2 against the glass surface of the vehicle, the arm 2 itself being driven in rotation by a motor, not visible, for example an electric motor carried by the vehicle.
Afin de relier le balai d’essuyage 4 à l’extrémité du bras 2, ledit balai d’essuyage 4 comprend un dispositif de connexion 8 comportant au moins un connecteur 10 qui porte une lame d’essuyage 12 du balai d’essuyage 4 et un ensemble de connexion 9, comprenant un adaptateur 14 pour la fixation du balai d’essuyage 4 au bras 2 et un arbre de rotation 42 configuré pour relier le connecteur 10 à l’adaptateur 14, l’adaptateur 14 étant apte à coopérer avec l’extrémité du bras 2 et est monté en rotation sur le connecteur 10 autour d’un axe de rotation R. On comprend notamment que la lame d’essuyage 12 du balai d’essuyage 4 est destinée à être au contact de la surface vitrée du véhicule. Par ailleurs, le connecteur 10 est configuré pour porter la lame d’essuyage 12, directement ou indirectement. In order to connect the wiper blade 4 to the end of the arm 2, said wiper blade 4 comprises a connection device 8 comprising at least one connector 10 which carries a wiping blade 12 of the wiping blade 4 and a connection assembly 9, comprising an adapter 14 for fixing the wiping blade 4 to the arm 2 and a rotation shaft 42 configured to connect the connector 10 to the adapter 14, the adapter 14 being able to cooperate with the end of the arm 2 and is mounted to rotate on the connector 10 around an axis of rotation R. It is understood in particular that the wiping blade 12 of the broom The wiper 4 is intended to be in contact with the glass surface of the vehicle. Furthermore, the connector 10 is configured to carry the wiping blade 12, directly or indirectly.
La rotation de l’adaptateur 14 et du connecteur 10 se fait au moyen d’un dispositif de rotation 38, cette rotation se faisant autour de l’axe de rotation R sensiblement parallèle à la direction transversale T. Une description plus détaillée du dispositif de rotation 38 sera faite dans la suite de la description. The rotation of the adapter 14 and the connector 10 is done by means of a rotation device 38, this rotation taking place around the axis of rotation R substantially parallel to the transverse direction T. A more detailed description of the rotation device rotation 38 will be made in the remainder of the description.
Tel que plus particulièrement visible sur la figure 2, l’adaptateur 14 s’étend principalement le long de la direction longitudinale L. L’adaptateur 14 comprend au moins une première paroi latérale 18, une deuxième paroi latérale 20 et une paroi supérieure 22, la paroi supérieure 22 étant interposée entre les deux parois latérales 18, 20. As more particularly visible in Figure 2, the adapter 14 extends mainly along the longitudinal direction L. The adapter 14 comprises at least a first side wall 18, a second side wall 20 and an upper wall 22, the upper wall 22 being interposed between the two side walls 18, 20.
Les parois latérales 18, 20 s’étendent principalement dans un plan parallèle aux directions longitudinale L et verticale V. Les parois latérales 18, 20 présentent ici un bord libre 24 et un bord commun 26 avec la paroi supérieure 22, chaque bord commun 26 joignant respectivement les parois latérales 18, 20 avec la paroi supérieure 22. The side walls 18, 20 extend mainly in a plane parallel to the longitudinal L and vertical directions V. The side walls 18, 20 here have a free edge 24 and a common edge 26 with the upper wall 22, each common edge 26 joining respectively the side walls 18, 20 with the upper wall 22.
La paroi supérieure 22 présente une courbe, tel que visible sur la figure 2. On comprend ici que la paroi supérieure 22 présente un profil courbé entre les bords commun 26 avec les parois latérales 18, 20, vue dans le plan perpendiculaire à la direction longitudinale L, en s’inscrivant dans un cercle. The upper wall 22 has a curve, as visible in Figure 2. It is understood here that the upper wall 22 has a curved profile between the common edges 26 with the side walls 18, 20, seen in the plane perpendicular to the longitudinal direction L, fitting into a circle.
On définit un volume interne 28 de l’adaptateur 14, visible en partie aux figures 2 et 3, ce volume interne 28 étant au moins en partie délimité par une des parois latérales 18, 20 et la paroi supérieure 22. Ici, le volume interne 28 est délimité par la première paroi latérale 18, la deuxième paroi latérale 20 et la paroi supérieure 22 de l’adaptateur 14. Selon une caractéristique de l’invention visible à la figure 3, l’adaptateur 14 comprend au moins une première paroi interne 30 qui participe à délimiter, avec la paroi supérieure 22, une zone de réception 34 du connecteur 10, particulièrement visible à la figure 3. Plus particulièrement, l’adaptateur 14 comprend la première paroi interne 30 et une deuxième paroi interne 32, parallèles l’une de l’autre selon la direction longitudinale L, lesdites paroi internes 30, 32 s’étendant au moins en partie dans le volume interne 28 de l’adaptateur 14. Plus précisément, les parois internes 30, 32 s’étendent dans un plan sensiblement parallèle aux directions longitudinale L et verticale V, en faisant saillie depuis la paroi supérieure 22 dans le volume interne 28 et de telle sorte qu’elles participent à délimiter, au moins avec la paroi supérieure 22, la zone de réception 34 destinée à recevoir une partie du connecteur 10, ici un organe de fixation 52 du connecteur 10. Selon l’exemple de l’invention illustré, la première paroi interne 30 est interposée transversalement entre la deuxième paroi interne 32 et la première paroi latérale 18. An internal volume 28 of the adapter 14 is defined, partly visible in Figures 2 and 3, this internal volume 28 being at least partly delimited by one of the side walls 18, 20 and the upper wall 22. Here, the internal volume 28 is delimited by the first side wall 18, the second side wall 20 and the upper wall 22 of the adapter 14. According to a characteristic of the invention visible in Figure 3, the adapter 14 comprises at least a first internal wall 30 which participates in delimiting, with the upper wall 22, a reception zone 34 of the connector 10, particularly visible in the figure 3. More particularly, the adapter 14 comprises the first internal wall 30 and a second internal wall 32, parallel to each other in the longitudinal direction L, said internal walls 30, 32 extending at least partly in the internal volume 28 of the adapter 14. More precisely, the internal walls 30, 32 extend in a plane substantially parallel to the longitudinal directions L and vertical V, projecting from the upper wall 22 into the internal volume 28 and such that they participate in delimiting, at least with the upper wall 22, the reception zone 34 intended to receive a part of the connector 10, here a fixing member 52 of the connector 10. According to the example of the invention illustrated , the first internal wall 30 is interposed transversely between the second internal wall 32 and the first side wall 18.
Par ailleurs, et tel que plus particulièrement visible sur la figure 3, l’adaptateur 14 comprend d’autres parois participant à délimiter la zone de réception 34, dont notamment des parois transversales 36. Plus particulièrement, les parois transversales 36 relient les parois internes 30, 32 de telle sorte que ces parois délimitent une zone de réception 34 parallélépipédique, ici rectangulaire. Ainsi, lorsque l’adaptateur 14 est monté sur le connecteur, ce dernier se loge au moins en partie dans la zone de réception 34 de l’adaptateur 14. Une telle coopération entre la zone de réception 34 de l’adaptateur 14 et le connecteur sera détaillée plus loin dans la description, notamment à la figure 4. Furthermore, and as more particularly visible in Figure 3, the adapter 14 comprises other walls participating in delimiting the reception zone 34, including in particular transverse walls 36. More particularly, the transverse walls 36 connect the internal walls 30, 32 so that these walls delimit a parallelepiped reception zone 34, here rectangular. Thus, when the adapter 14 is mounted on the connector, the latter is housed at least partly in the reception zone 34 of the adapter 14. Such cooperation between the reception zone 34 of the adapter 14 and the connector will be detailed later in the description, in particular in Figure 4.
Comme mentionné auparavant, l’adaptateur 14 est monté en rotation sur le connecteur au moyen de l’arbre de rotation 42 et d’un dispositif de rotation 38. Ce dernier comprend plusieurs éléments coopérant les uns avec les autres et disposés d’une part sur le connecteur et d’autre part sur l’adaptateur 14. Dans un premier temps, les éléments du dispositif de rotation 38 formés sur l’adaptateur 14 vont être décrits. As mentioned previously, the adapter 14 is rotatably mounted on the connector by means of the rotation shaft 42 and a rotation device 38. The latter comprises several elements cooperating with each other and arranged on the one hand on the connector and secondly on the adapter 14. Firstly, the elements of the rotation device 38 formed on the adapter 14 will be described.
Ainsi, et comme visible sur la figure 3, au moins une de la première paroi interne 30 et/ou de la deuxième paroi interne 32 comprend un palier de rotation 40 dans lequel se loge au moins en partie l’arbre de rotation 42. Plus particulièrement et selon l’exemple de l’invention, chacune de la première paroi interne 30 et de la deuxième paroi interne 32 comprend un palier de rotation 42 dans lequel se loge au moins en partie l’arbre de rotation 42. Les paliers de rotation 40 sont notamment alignés le long de l’axe de rotation R, et sont destinés à recevoir au moins en partie l’arbre de rotation 42, visible aux figures 3 ou 4. On comprend donc que le palier de rotation 40 de chacune des parois internes 30, 32 est traversant. De plus, selon l’exemple de l’invention, les paliers de rotation 40 sont ici circulaires de telle sorte qu’ils coopèrent avec l’arbre de rotation 42, ici de forme cylindrique. Thus, and as visible in Figure 3, at least one of the first internal wall 30 and/or the second internal wall 32 comprises a rotation bearing 40 in which the rotation shaft 42 is housed at least in part. More particularly and according to the example of the invention, each of the first internal wall 30 and the second internal wall 32 comprises a rotation bearing 42 in which the rotation shaft 42 is housed at least in part. The rotation bearings 40 are in particular aligned along the axis of rotation R, and are intended to receive at least in part of the rotation shaft 42, visible in Figures 3 or 4. We therefore understand that the rotation bearing 40 of each of the internal walls 30, 32 is through. Furthermore, according to the example of the invention, the rotation bearings 40 are here circular such that they cooperate with the rotation shaft 42, here of cylindrical shape.
Selon une caractéristique de l’invention, l’adaptateur 14 comprend au moins un organe de butée 44 configuré pour bloquer l’arbre de rotation 42 en translation dans l’au moins un palier de rotation 40, selon un premier sens Tl le long d’une direction T, parallèle et confondue avec l’axe de rotation R. Le premier sens Tl est dirigé depuis la deuxième paroi interne 32 vers la première paroi interne 30 de l’adaptateur 14. Ainsi, l’organe de butée 44 est configuré pour bloquer l’arbre de rotation 42 dans le palier de rotation 40 de chacune de la première paroi interne 30 et de la deuxième paroi interne 32, suivant le premier sens Tl. L’organe de butée 44 fait saillie dans le volume interne 28 de l’adaptateur 14 et de telle sorte que ledit organe de butée 44 s’étende au moins en partie en regard du palier de rotation 40. De manière plus précise et selon un exemple de l’invention, l’organe de butée 44 fait saillie d’une des parois latérales 18, 20 de l’adaptateur 14, disposée à l’opposé transversalement d’un volume de réception 46 du bras dans l’adaptateur 14 par rapport à la zone de réception 34 du connecteur 10, ici la première paroi latérale 18. Le volume de réception 46 du bras sera décrit plus loin dans la suite de la description. According to one characteristic of the invention, the adapter 14 comprises at least one stop member 44 configured to block the rotation shaft 42 in translation in the at least one rotation bearing 40, in a first direction Tl along 'a direction T, parallel and coincident with the axis of rotation R. The first direction Tl is directed from the second internal wall 32 towards the first internal wall 30 of the adapter 14. Thus, the stop member 44 is configured to block the rotation shaft 42 in the rotation bearing 40 of each of the first internal wall 30 and the second internal wall 32, in the first direction Tl. The stop member 44 projects into the internal volume 28 of the adapter 14 and such that said stop member 44 extends at least partly opposite the rotation bearing 40. More precisely and according to an example of the invention, the stop member 44 projects of one of the side walls 18, 20 of the adapter 14, arranged transversely opposite a receiving volume 46 of the arm in the adapter 14 relative to the receiving zone 34 of the connector 10, here the first side wall 18. The receiving volume 46 of the arm will be described later in the remainder of the description.
Selon un autre exemple de l’invention non illustré, l’organe de butée peut faire saillie dans le volume interne depuis la paroi supérieure et de telle sorte qu’il s’étende au moins en partie en regard des paliers de rotation. On comprend alors que l’organe de butée peut faire saillie de n’importe quelle paroi de l’adaptateur, tant que ledit organe de butée permet de bloquer l’arbre de rotation dans l’au moins un palier de rotation suivant le premier sens. According to another example of the invention not illustrated, the stop member can project into the internal volume from the upper wall and in such a way that it extends at least partly facing the rotation bearings. It is then understood that the stop member can project from any wall of the adapter, as long as said stop member makes it possible to block the rotation shaft in the at least one rotation bearing in the first direction. .
Selon l’exemple de l’invention illustré, l’organe de butée 44 peut prendre la forme d’au moins deux nervures 44a, 44b distinctes l’une de l’autre. On entend par nervures 44a, 44b distinctes, des nervures 44a, 44b qui ne présentent pas de contact de leur matière l’une avec l’autre et qui s’étendent à distance non nulle l’une de l’autre. De manière plus précise, ici, chacune des nervures 44a, 44b formant l’organe de butée 44 s’étend dans la direction transversale T et verticale V et est à distance non nulle de l’autre nervure 44a, 44b suivant la direction longitudinale L de l’adaptateur 14. According to the example of the invention illustrated, the stop member 44 can take the form of at least two ribs 44a, 44b distinct from each other. By distinct ribs 44a, 44b is meant ribs 44a, 44b which do not have any contact of their material with one another and which extend at a non-zero distance from one another. More precisely, here, each of the ribs 44a, 44b forming the stop member 44 extends in the transverse direction T and vertical direction V and is at a non-zero distance from the other rib 44a, 44b in the longitudinal direction L of the adapter 14.
Selon un autre exemple de l’invention non illustré, l’organe de butée peut être formé par une saillie unique, formant un plot, qui s’étend transversalement depuis la première paroi latérale et/ou de la paroi supérieure de l’adaptateur et en regard du palier de rotation des parois internes. Dans l’exemple où un tel plot ou une telle nervure fait saillie de la paroi supérieure de l’adaptateur, ledit plot ou ladite nervure est néanmoins séparé de la paroi latérale de l’adaptateur. According to another example of the invention not illustrated, the stop member can be formed by a single projection, forming a stud, which extends transversely from the first side wall and/or the upper wall of the adapter and opposite the rotation bearing of the internal walls. In the example where such a stud or such a rib projects from the upper wall of the adapter, said stud or said rib is nevertheless separated from the side wall of the adapter.
Indépendamment de la forme de l’organe de butée 44, on définit au moins une surface de contact 48 dudit organe de butée 44, destinée à être en contact de l’arbre de rotation 42 évoqué précédemment. Autrement dit, l’au moins une surface de contact 48 s’étend en regard du palier de rotation 40 des parois internes 30, 32. On comprend par ailleurs que lorsque l’organe de butée 44 est formé par les deux nervures 44a, 44b tel qu’illustré à la figure 3, chacune des nervures 44a, 44b présente une surface de contact 48 distinctes, lesdites surfaces de contact 48 de chacune des nervures 44a, 44b s’étendant dans un plan commun à la direction longitudinale L et verticale V de l’adaptateur 14. Ainsi, on définit une distance transversale Di entre l’organe de butée 44 et la première paroi interne 30, et plus particulièrement entre l’au moins une surface de contact 48 de l’organe de butée 44 et la première paroi interne 30, la distance transversale Di étant prise le long d’une droite parallèle à la direction transversale T de l’adaptateur 14. Selon l’invention, la distance transversale Di est comprise entre o et 7,7mm. De préférence la distance transversale Di est non nulle. De manière encore plus préférée, la distance est comprise entre 3,5mm avec une tolérance de +/- 0,1mm et 3,7mm avec une tolérance de +/- 0,1mm. Independently of the shape of the stop member 44, at least one contact surface 48 of said stop member 44 is defined, intended to be in contact with the rotation shaft 42 mentioned above. In other words, the at least one contact surface 48 extends opposite the rotation bearing 40 of the internal walls 30, 32. It is also understood that when the stop member 44 is formed by the two ribs 44a, 44b as illustrated in Figure 3, each of the ribs 44a, 44b has a distinct contact surface 48, said contact surfaces 48 of each of the ribs 44a, 44b extending in a plane common to the longitudinal L and vertical direction V of the adapter 14. Thus, a transverse distance Di is defined between the stop member 44 and the first internal wall 30, and more particularly between the at least one contact surface 48 of the stop member 44 and the first internal wall 30, the transverse distance Di being taken along a straight line parallel to the transverse direction T of the adapter 14. According to the invention, the transverse distance Di is between 0 and 7.7mm. Preferably the transverse distance Di is non-zero. Even more preferably, the distance is between 3.5mm with a tolerance of +/- 0.1mm and 3.7mm with a tolerance of +/- 0.1mm.
De plus, selon un exemple particulier de l’invention, un centre C de l’organe de butée 44, visible à la figure 4, est coaxial avec l’axe de rotation R de l’adaptateur 14. On comprend que dans l’exemple de l’invention illustré comprenant l’organe de butée 44 sous forme de nervures 44a, 44a, le centre C est défini comme un point équidistant entre les deux nervures 44a, 44b pris le long de la direction longitudinale L de l’adaptateur 14. On permet ainsi à la surface de contact 48 d’avoir un contact optimal avec une extrémité libre de l’arbre de rotation 42. Furthermore, according to a particular example of the invention, a center C of the stop member 44, visible in Figure 4, is coaxial with the axis of rotation R of the adapter 14. It is understood that in the example of the invention illustrated comprising the stop member 44 in the form of ribs 44a, 44a, the center C is defined as a point equidistant between the two ribs 44a, 44b taken along the longitudinal direction L of the adapter 14 This allows the contact surface 48 to have optimal contact with a free end of the rotation shaft 42.
Tel que visible aux figures 2 et 3, la deuxième paroi latérale 20 de l’adaptateur 14 comprend un dégagement 50 disposé en regard du palier de rotation 40 des parois internes 30, 32. De manière plus précise, le dégagement 50 présente une forme circulaire dont un centre est confondu sur l’axe de rotation R. Un tel dégagement 50 permet de faciliter l’insertion de l’arbre de rotation 42 dans le palier de rotation 40 des parois internes 30, 32. As visible in Figures 2 and 3, the second side wall 20 of the adapter 14 comprises a clearance 50 disposed opposite the rotation bearing 40 of the walls internal 30, 32. More precisely, the clearance 50 has a circular shape, a center of which coincides with the axis of rotation R. Such a clearance 50 makes it possible to facilitate the insertion of the rotation shaft 42 into the bearing rotation 40 of the internal walls 30, 32.
Selon la figure 4, on définit une première dimension Al de l’arbre de rotation 42 prise le long d’une direction d’allongement principale Pi dudit arbre de rotation 42. On comprend ici que, lorsque l’arbre de rotation 42 est disposé dans le palier de rotation 40, sa direction d’allongement principale Pi est confondue avec l’axe de rotation R de l’adaptateur 14. Ainsi, selon l’invention, la première dimension Al est au moins égale à une deuxième dimension A2 prise entre le palier de rotation 40 de la deuxième paroi interne 32 et l’au moins une surface de contact 48 de l’organe de butée 44. Cet aspect est intéressant pour éviter que l’arbre de rotation s’échappe du palier de rotation 40 ménagé dans la deuxième paroi interne 32. According to Figure 4, we define a first dimension Al of the rotation shaft 42 taken along a main elongation direction Pi of said rotation shaft 42. We understand here that, when the rotation shaft 42 is arranged in the rotation bearing 40, its main direction of elongation Pi coincides with the axis of rotation R of the adapter 14. Thus, according to the invention, the first dimension Al is at least equal to a second dimension A2 taken between the rotation bearing 40 of the second internal wall 32 and the at least one contact surface 48 of the stop member 44. This aspect is interesting to prevent the rotation shaft from escaping from the rotation bearing 40 provided in the second internal wall 32.
Tel que visible à la figure 4, le connecteur 10 comprend au moins un organe de fixation 52 logé dans la zone de réception 34 de l’adaptateur 14 lorsque ce dernier est monté sur ledit connecteur 10. L’organe de fixation 52 s’étend principalement selon la direction longitudinale L et verticale V et comprend une complémentarité de forme avec la zone de réception 34. Des flancs de l’organe de fixation 52 sont en contact glissant sur des faces intérieures de chacune des parois interne 30, 32. As visible in Figure 4, the connector 10 comprises at least one fixing member 52 housed in the receiving zone 34 of the adapter 14 when the latter is mounted on said connector 10. The fixing member 52 extends mainly in the longitudinal direction L and vertical direction V and comprises a complementary shape with the reception zone 34. Flanks of the fixing member 52 are in sliding contact on the interior faces of each of the internal walls 30, 32.
Par ailleurs, l’organe de fixation 52 comprend un alésage traversant 54 formé de telle sorte que ledit alésage traversant 54 soit aligné sur l’axe de rotation R, en regard du palier de rotation 40 des parois internes 30, 32 de l’adaptateur 14. Ainsi, on comprend que lorsque le dispositif de connexion 8 est assemblé, l’arbre de rotation 42 est inséré dans les paliers de rotation 40 et dans l’alésage traversant 54, de telle sorte à relier en rotation l’adaptateur 14 avec le connecteur 10. Furthermore, the fixing member 52 comprises a through bore 54 formed such that said through bore 54 is aligned on the axis of rotation R, facing the rotation bearing 40 of the internal walls 30, 32 of the adapter 14. Thus, we understand that when the connection device 8 is assembled, the rotation shaft 42 is inserted in the rotation bearings 40 and in the through bore 54, so as to connect in rotation the adapter 14 with connector 10.
Selon l’invention, l’adaptateur 14 de l’ensemble de connexion 9 comprend un dispositif de verrouillage 56 visible en partie à la figure 3 et destiné à solidariser longitudinalement l’adaptateur 14 par rapport au bras 2 du système d’essuyage, le dispositif de verrouillage 56 étant monté basculant sur la paroi supérieure 22 autour d’un axe de basculement I, parallèle à la direction longitudinale de l’adaptateur 14. Le dispositif de verrouillage 56 comprend au moins un moyen de limitation 58 de son basculement autour de l’axe de basculement I qui vient en appui contre la deuxième paroi interne 32. Plus particulièrement, le dispositif de verrouillage 56 comprend au moins un organe de poussée 62 et un organe de blocage 60, l’organe de poussée 62 s’inscrivant dans un profil de la paroi supérieure 22 tandis que l’organe de blocage 60 s’étend au moins en partie dans le volume de réception 46 destiné à recevoir la tige du bras 2. According to the invention, the adapter 14 of the connection assembly 9 comprises a locking device 56 partially visible in Figure 3 and intended to secure the adapter 14 longitudinally relative to the arm 2 of the wiping system, the locking device 56 being tiltably mounted on the upper wall 22 around a tilting axis I, parallel to the longitudinal direction of the adapter 14. The locking device 56 comprises at least one means 58 for limiting its tilting around the tilting axis I which bears against the second internal wall 32. More particularly, the locking device 56 comprises at least one pushing member 62 and a blocking member 60, the pushing member 62 fitting into a profile of the upper wall 22 while the blocking member 60 fits extends at least partly into the receiving volume 46 intended to receive the rod of the arm 2.
L’organe de poussée 62 est l’organe sur lequel un utilisateur exerce une force pour permettre au dispositif de verrouillage 56 de basculer autour de l’axe de basculement I. The pushing member 62 is the member on which a user exerts a force to allow the locking device 56 to tilt around the tilting axis I.
L’organe de blocage 60 quant à lui est l’organe du dispositif de verrouillage 56 configuré pour être au moins en partie en contact avec la tige du bras 2, solidarisant et/ou désolidarisant longitudinalement l’adaptateur 14 par rapport au bras 2. On comprend que c’est l’organe qui interagit avec le bras 2 pour lier l’adaptateur 14 avec ledit bras 2. The blocking member 60 for its part is the member of the locking device 56 configured to be at least partly in contact with the rod of the arm 2, securing and/or longitudinally detaching the adapter 14 from the arm 2. We understand that it is the member which interacts with the arm 2 to link the adapter 14 with said arm 2.
Tel que plus particulièrement visible sur la figure 3, l’organe de blocage 60 s’étend depuis l’organe de poussée 62 vers le volume de réception 46, l’organe de blocage 60 comprenant une portion coudée et une extrémité libre 64 disposée dans le volume de réception 46 lorsque le dispositif de verrouillage 56 est dans une position de verrouillage de l’adaptateur 14 sur le bras 2. L’extrémité libre 64 prend la forme d’un arbre s’étendant principalement le long de la direction longitudinale L et dans le volume de réception 46. As more particularly visible in Figure 3, the blocking member 60 extends from the pushing member 62 towards the receiving volume 46, the blocking member 60 comprising a bent portion and a free end 64 arranged in the receiving volume 46 when the locking device 56 is in a locking position of the adapter 14 on the arm 2. The free end 64 takes the form of a shaft extending mainly along the longitudinal direction L and in the reception volume 46.
Selon l’exemple de l’invention illustré, le volume de réception 46 du bras 2 comprend au moins un conduit de guidage 66, visible à la figure 2, le conduit de guidage 66 étant destiné à recevoir et à guider une translation du bras en s’étendant au moins en partie dans le volume interne 28 de l’adaptateur 14. According to the example of the invention illustrated, the receiving volume 46 of the arm 2 comprises at least one guide conduit 66, visible in Figure 2, the guide conduit 66 being intended to receive and guide a translation of the arm in extending at least partly into the internal volume 28 of the adapter 14.
Plus particulièrement, le conduit de guidage 66 comprend une première extrémité longitudinale 66a par laquelle le bras est destiné à entrer dans le conduit de guidage 66 et une deuxième extrémité longitudinale 66b adjacente au dispositif de verrouillage 56. More particularly, the guide conduit 66 comprises a first longitudinal end 66a through which the arm is intended to enter the guide conduit 66 and a second longitudinal end 66b adjacent to the locking device 56.
L’adaptateur 14 comprend également au moins un renfort 68 qui s’étend entre la deuxième paroi interne 32 et la deuxième paroi latérale 20. Le renfort 68 comprend notamment une paroi s’étendant principalement, par exemple, dans un plan sensiblement perpendiculaire à la direction longitudinale L. Le renfort 68 permet de renforcer la structure de l’adaptateur 14, et d’optimiser sa rigidité. Par ailleurs, et tel que visible sur la figure 3, le renfort 68 comprend une ouverture 70 participant à délimiter au moins en partie le volume de réception 46. On comprend que l’ouverture 70 est destinée à recevoir au moins une partie de la tige 6 du bras 2. The adapter 14 also comprises at least one reinforcement 68 which extends between the second internal wall 32 and the second side wall 20. The reinforcement 68 notably comprises a wall extending mainly, for example, in a plane substantially perpendicular to the longitudinal direction L. The reinforcement 68 makes it possible to reinforce the structure of the adapter 14, and to optimize its rigidity. Moreover, and such as visible in Figure 3, the reinforcement 68 comprises an opening 70 helping to delimit at least partly the receiving volume 46. It is understood that the opening 70 is intended to receive at least part of the rod 6 of the arm 2.
Ainsi, l’ouverture 70 du renfort 68 et le conduit de guidage 66 sont alignés le long d’une direction parallèle à la direction longitudinale L, la tige du bras s’étendant dès lors le long de la direction longitudinale L à travers le conduit de guidage 66 et l’ouverture 70 du renfort 68. Thus, the opening 70 of the reinforcement 68 and the guide conduit 66 are aligned along a direction parallel to the longitudinal direction L, the rod of the arm therefore extending along the longitudinal direction L through the conduit guide 66 and the opening 70 of the reinforcement 68.
Selon un aspect, le volume de réception 46 est décalé latéralement par rapport à la zone de réception 34 du connecteur. According to one aspect, the reception volume 46 is offset laterally relative to the reception zone 34 of the connector.
Plus précisément, le volume de réception 46 est plus proche de la deuxième paroi latérale 20 que la zone de réception 34. En d’autres termes, le volume de réception 46 est disposé entre la zone de réception 34 et la deuxième paroi latérale 20. On comprend alors que le volume de réception 46 s’étend au moins en partie en regard du au moins un palier de rotation 40 de l’adaptateur 14. Ici, le volume de réception 46 s’étend au moins en partie entre la deuxième paroi latérale 20 et la deuxième paroi interne 32, de telle sorte qu’il soit au moins en partie en regard du palier de rotation 40 de la première paroi interne 30 et de la deuxième paroi interne 32. On comprend alors que dans une configuration montée du bras dans le volume de réception 46 de l’adaptateur 14 telle que visible à la figure 3, la tige 6 dudit bras s’étend au moins en partie en regard du au moins un palier de rotation 40 de l’adaptateur 14. More precisely, the receiving volume 46 is closer to the second side wall 20 than the receiving zone 34. In other words, the receiving volume 46 is arranged between the receiving zone 34 and the second side wall 20. It is then understood that the receiving volume 46 extends at least partly opposite the at least one rotation bearing 40 of the adapter 14. Here, the receiving volume 46 extends at least partly between the second wall side 20 and the second internal wall 32, such that it is at least partly facing the rotation bearing 40 of the first internal wall 30 and the second internal wall 32. It is then understood that in a mounted configuration of the arm in the receiving volume 46 of the adapter 14 as visible in Figure 3, the rod 6 of said arm extends at least partly opposite the at least one rotation bearing 40 of the adapter 14.
Par ailleurs, au moins une extrémité de la tige 6 prend une forme complémentaire au volume de réception 46 de l’adaptateur 14, la tige présentant une encoche 6a coopérant avec le dispositif de verrouillage 56 pour bloquer longitudinalement la position de l’adaptateur 14 sur la tige du bras. On comprend que l’extrémité libre 64 de l’organe de blocage 60 est disposée dans l’encoche 6a de la tige 6 de sorte à bloquer longitudinalement la tige 6 dans le volume de réception 46. Furthermore, at least one end of the rod 6 takes a shape complementary to the receiving volume 46 of the adapter 14, the rod having a notch 6a cooperating with the locking device 56 to longitudinally lock the position of the adapter 14 on the arm shaft. It is understood that the free end 64 of the blocking member 60 is arranged in the notch 6a of the rod 6 so as to block the rod 6 longitudinally in the receiving volume 46.
On comprend que pour démonter le balai d’essuyage par rapport au bras 2, le dispositif de verrouillage 56 est basculé autour de la direction de basculement I jusqu’à ce que le moyen de limitation 58 bute contre la deuxième paroi interne 32. Ce basculement est suffisant pour libérer l’adaptateur 14 par rapport au bras, tout en limitant le risque de casse du dispositif de verrouillage 56. It is understood that to disassemble the wiper blade relative to the arm 2, the locking device 56 is tilted around the tilting direction I until the limiting means 58 abuts against the second internal wall 32. This tilting is sufficient to release the adapter 14 relative to the arm, while limiting the risk of breakage of the locking device 56.
Comme illustré à la figure 4 et évoqué ci-dessus, la tige 6 du bras 2 s’étend au moins en partie en regard du palier de rotation 40 de la deuxième paroi interne 32 de l’adaptateur 14 et de telle sorte qu’au moins une portion de la tige 6 forme une zone de butée 72 à l’encontre de l’arbre de rotation 42 lorsque celui-ci est logé dans le palier de rotation 40. Dit autrement, à l’état monté, le bras est disposé dans le volume de réception 46 de l’adaptateur 14 de telle sorte qu’il bloque l’arbre de rotation 42 en translation dans l’au moins un palier de rotation 40, selon un deuxième sens T2 le long de la direction T. On comprend alors que le deuxième sens T2 est opposé au premier sens Tl selon l’axe de rotation R de l’adaptateur 14 et donc selon la direction d’allongement principal Pi de l’arbre de rotation 42. Le deuxième sens T2 est ainsi dirigé depuis la première paroi interne 30 vers la deuxième paroi interne 32 de l’adaptateur 14. As illustrated in Figure 4 and mentioned above, the rod 6 of the arm 2 extends at least partly facing the rotation bearing 40 of the second internal wall 32 of the adapter 14 and such that at least one portion of the rod 6 forms an abutment zone 72 against the rotation shaft 42 when it is housed in the rotation bearing 40. In other words, in the mounted state, the arm is arranged in the receiving volume 46 of the adapter 14 in such a way that it blocks the rotation shaft 42 in translation in the at least one rotation bearing 40, in a second direction T2 along the direction T. It is then understood that the second direction T2 is opposite to the first direction Tl along the axis of rotation R of the adapter 14 and therefore in the direction of main elongation Pi of the rotation shaft 42. The second direction T2 is thus directed from the first internal wall 30 towards the second internal wall 32 of the adapter 14.
Par ailleurs, on définit une première distance D2 prise entre la zone de butée 72 de la tige 6 et la deuxième paroi interne 32, la première distance D2 étant strictement inférieure à la distance transversale Di évoquée précédemment. On comprend qu’une telle caractéristique permet à l’arbre de rotation 42 d’être maintenu dans le palier de rotation 40 de l’adaptateur 14 et dans l’alésage traversant 54 du connecteur. Dans l’illustration, D2 est proche de zéro mm, mais une distance de quelques millimètres est autorisée pour D2, tant que cette dimension D2 reste inférieure à la dimension transversale Di. On garantit ainsi que l’arbre de rotation 42 ne peut pas s’échapper du palier de rotation 40 de la première paroi interne 30. Furthermore, we define a first distance D2 taken between the abutment zone 72 of the rod 6 and the second internal wall 32, the first distance D2 being strictly less than the transverse distance Di mentioned previously. It is understood that such a characteristic allows the rotation shaft 42 to be held in the rotation bearing 40 of the adapter 14 and in the through bore 54 of the connector. In the illustration, D2 is close to zero mm, but a distance of a few millimeters is allowed for D2, as long as this dimension D2 remains less than the transverse dimension Di. This ensures that the rotation shaft 42 cannot escape from the rotation bearing 40 of the first internal wall 30.
Par ailleurs, selon une première alternative, l’arbre de rotation 42 est reçu dans le palier de rotation 40 de telle sorte qu’il soit monté libre ou glissant librement dans ledit palier de rotation 40 et qu’il soit par la suite bloqué en position dans le palier de rotation 40 suivant le deuxième sens T2, par la zone de butée 72 de la tige 6 tel qu’évoqué ci-dessus. Selon une deuxième alternative, l’arbre de rotation 42 est reçu dans le palier de rotation 40 de telle sorte qu’il soit monté légèrement serré dans au moins un des paliers de rotation 40 afin de limiter l’échappement de l’arbre de rotation 42 en dehors des paliers de rotation 40, par exemple lors du montage de balai d’essuyage, ledit arbre de rotation 42 étant par la suite bloqué en position dans les paliers de rotation 40 par la zone de butée 72 de la tige 6, selon le deuxième sens T2. Furthermore, according to a first alternative, the rotation shaft 42 is received in the rotation bearing 40 such that it is mounted free or sliding freely in said rotation bearing 40 and that it is subsequently blocked in place. position in the rotation bearing 40 in the second direction T2, by the stop zone 72 of the rod 6 as mentioned above. According to a second alternative, the rotation shaft 42 is received in the rotation bearing 40 such that it is mounted slightly tight in at least one of the rotation bearings 40 in order to limit the escape of the rotation shaft 42 outside the rotation bearings 40, for example when mounting a wiper blade, said rotation shaft 42 subsequently being blocked in position in the rotation bearings 40 by the stop zone 72 of the rod 6, according to the second sense T2.
En ce qui concerne le processus de montage, on loge d’abord le connecteur dans la zone de réception 34 de l’adaptateur, puis on enfile l’arbre de rotation 42 dans le palier de rotation 40 de l’adaptateur 14 et dans l’alésage traversant 54 du connecteur, puis on dispose la tige 6 du bras 2 dans le volume de réception 46 de l’adaptateur 14 afin de bloquer ledit arbre de rotation 42 au moyen de la zone de butée 72 de la tige 6 du bras. Ainsi monté, l’arbre de rotation 42 ne peut pas s’échapper puisqu’il est bloqué selon le premier sens Tl par l’organe de butée 44 et selon le deuxième sens T2 par la zone de butée 72 de la tige 6. Regarding the assembly process, the connector is first placed in the receiving area 34 of the adapter, then the rotation shaft 42 is threaded into the rotation bearing 40 of the adapter 14 and in the through bore 54 of the connector, then the rod 6 of the arm 2 is placed in the receiving volume 46 of the adapter 14 in order to block said rotation shaft 42 by means of the abutment zone 72 of the rod 6 of the arm. Thus mounted, the rotation shaft 42 cannot escape since it is blocked in the first direction Tl by the stop member 44 and in the second direction T2 by the stop zone 72 of the rod 6.
La présente invention ne saurait toutefois se limiter aux moyens et configurations décrits et illustrés ici et elle s’étend également à tout moyen et configuration équivalents ainsi qu’à toute combinaison techniquement opérante de tels moyens. The present invention cannot, however, be limited to the means and configurations described and illustrated here and it also extends to any equivalent means and configuration as well as to any technically effective combination of such means.
