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 moyens de connexion mis en œuvre entre un bras d’essuie-glace et un balai d’essuyage d’un tel système d’essuyage.The field of the present invention is that of wiper systems intended for motor vehicles. More particularly, the field of the present invention is that of the connection means implemented between a windscreen wiper arm and a wiper blade of such a wiper system.
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 entraîné 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’adapteur est agencé entre le bras d’essuie-glace et un connecteur relié au balai d’essuyage.Motor vehicles are commonly equipped with wiping systems intended to clean their glass surfaces, and in particular their windshield. Such wiper systems comprise at least one wiper arm and a wiper blade driven by the wiper arm. The wiper arm is connected to an electric motor of the vehicle and the wiper blade comprises at least one wiper blade adapted to come into contact with the glazed 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 wiper arm and a connector connected to the wiper blade.
L’adaptateur est alors assemblé avec le connecteur de telle sorte qu’ils soient mobiles en rotation l’un par rapport à l’autre. On permet ainsi au balai d’essuyage d’être mobile en rotation afin qu’il épouse au mieux la surface vitrée du véhicule. Le montage en rotation s’effectue notamment grâce à un moyen de rotation de l’adaptateur comprenant au moins un palier et un plot cylindrique aptes à coopérer avec des moyens complémentaires du connecteur.The adapter is then assembled with the connector in such a way that they are rotatable relative to each other. This allows the wiper blade to be mobile in rotation so that it best matches the glazed surface of the vehicle. The rotational mounting is carried out in particular by means of a means of rotation of the adapter comprising at least one bearing and a cylindrical stud capable of cooperating with complementary means of the connector.
Un problème des moyens de rotation actuels réside notamment en ce que leur maintien en coopération avec le connecteur n’est pas optimal. En effet, bien que le moyen de rotation de l’adaptateur assure une rotation acceptable de ce dernier par rapport au connecteur, son maintien est parfois mis en défaut, notamment quand il se produit des efforts qui conduisent à désaxer l’adaptateur par rapport au connecteur. L’effort de retenu mécanique entre l’adapteur et le connecteur est ainsi trop faible.A problem with the current means of rotation resides in particular in the fact that their maintenance in cooperation with the connector is not optimal. Indeed, although the means of rotation of the adapter ensures an acceptable rotation of the latter relative to the connector, its maintenance is sometimes faulty, in particular when there are forces which lead to the adapter being off-axis relative to the connector. connector. The mechanical retaining force between the adapter and the connector is therefore too low.
Le but de la présente invention est donc d’améliorer le moyen de rotation actuel d’un adaptateur, sans complexifier sa conception, sa réalisation, ni augmenter son coût de production. The object of the present invention is therefore to improve the current means of rotation of an adapter, without complicating its design, its production, or increasing its production cost.
L’invention porte donc sur un adaptateur pour la fixation d’un balai d’essuyage à un bras d’un système d’essuyage, l’adaptateur étant configuré pour être monté pivotant autour d’un axe de rotation sur un connecteur du balai d’essuyage, l’adaptateur comprenant au moins deux parois latérales opposées l’une de l’autre selon une direction transversale de l’adaptateur et de telle sorte qu’elles délimitent au moins en partie un espace de réception pour le connecteur, l’adaptateur comprenant au moins un moyen de rotation de l’adaptateur par rapport au connecteur formé sur les parois latérales, le moyen de rotation comprenant au moins un palier qui s’ouvre sur l’espace de réception, l’adaptateur étant caractérisé en ce que le palier comprend au moins trois points configurés pour prendre appui sur le connecteur, les trois points étant séparés les uns des autres par des secteurs angulaires dépourvus de matière.The invention therefore relates to an adapter for attaching a wiper blade to an arm of a wiping system, the adapter being configured to be pivotally mounted around an axis of rotation on a connector of the blade. wiper, the adapter comprising at least two side walls opposite each other in a transverse direction of the adapter and such that they delimit at least in part a receiving space for the connector, the adapter comprising at least one means for rotating the adapter relative to the connector formed on the side walls, the means for rotating comprising at least one bearing which opens onto the receiving space, the adapter being characterized in that that the bearing comprises at least three points configured to bear on the connector, the three points being separated from each other by angular sectors devoid of material.
On comprend que le palier est ménagé dans l’une des parois latérales de l’adaptateur. On comprend que le palier comprend une zone de réception ménagée dans la paroi latérale. It is understood that the bearing is formed in one of the side walls of the adapter. It is understood that the bearing comprises a reception zone made in the side wall.
On comprend que la zone de réception est configurée pour recevoir un élément de rotation du connecteur. Par exemple, la zone de réception est dépourvue de matière. It is understood that the reception zone is configured to receive a rotation element of the connector. For example, the reception area is devoid of material.
Par exemple par complémentarité de forme. Le palier est configuré pour permettre le pivotement de l’adaptateur par rapport au connecteur lorsque l’adaptateur est monté sur le connecteur. For example by complementarity of form. The bearing is configured to allow pivoting of the adapter relative to the connector when the adapter is mounted on the connector.
On comprend que le palier est formé par trois point solidaires de la paroi latérale. Par exemple, les trois points sont formés avec la paroi latérale de l’adaptateur. It is understood that the bearing is formed by three points integral with the side wall. For example, the three points are formed with the side wall of the adapter.
On comprend que les trois points délimitent la zone de réception du palier. It is understood that the three points delimit the reception zone of the landing.
Les trois points peuvent délimiter une zone de réception circulaire ou cylindrique. The three points can delimit a circular or cylindrical landing zone.
Dans certains modes de réalisation, les trois points délimitent une zone de réception configurée pour recevoir un élément de rotation du connecteur, la zone de réception étant circulaire. In certain embodiments, the three points delimit a reception zone configured to receive a rotation element of the connector, the reception zone being circular.
Par exemple les au moins trois points sont répartis autour de la circonférence de la zone de réception sensiblement uniformément ou équitablement. Par exemple les au moins trois points sont à égale distance les uns des autres. For example, the at least three points are distributed around the circumference of the reception zone substantially uniformly or equitably. For example the at least three points are equidistant from each other.
Par exemple, selon une direction longitudinale de l’adaptateur, les au moins trois points sont disposés en quinconce. For example, in a longitudinal direction of the adapter, the at least three points are staggered.
Le balai d’essuyage et le bras font partis d’un système d’essuyage d’un véhicule et destiné à nettoyer au moins en partie une surface vitrée dudit véhicule. L’adaptateur est alors monté pivotant par rapport au connecteur de telle sorte que le balai d’essuyage, et notamment une lame qu’il porte, suive une courbe de la surface vitrée. The wiper blade and the arm are part of a vehicle wiping system and intended to clean at least part of a glass surface of said vehicle. The adapter is then pivotally mounted relative to the connector so that the wiper blade, and in particular a blade that it carries, follows a curve of the glazed surface.
Cette rotation de l’adaptateur par rapport au connecteur s’effectue notamment grâce au moyen de rotation de l’adaptateur comprenant au moins le palier et un plot cylindrique sur la paroi latérale opposée à celle qui porte le palier. Le palier comprend notamment au moins trois points aptes à prendre appui sur le connecteur et plus précisément sur une saillie cylindrique destinée à coopérer avec le palier du moyen de rotation. Chacun des trois points est alors séparé par au moins un secteur angulaire dépourvu de matière. On entend alors par dépourvu de matière, le fait que le secteur angulaire forme une zone du palier sur laquelle la saillie cylindrique du connecteur ne prend pas appui. This rotation of the adapter relative to the connector is carried out in particular thanks to the means of rotation of the adapter comprising at least the bearing and a cylindrical stud on the side wall opposite that which carries the bearing. The bearing notably comprises at least three points able to bear on the connector and more precisely on a cylindrical projection intended to cooperate with the bearing of the rotation means. Each of the three points is then separated by at least one angular sector devoid of matter. The term devoid of material then means the fact that the angular sector forms a zone of the bearing on which the cylindrical projection of the connector does not rest.
On tire avantage du moyen de rotation de l’adaptateur, et notamment de son palier comprenant les au moins trois points configurés pour prendre appui sur le connecteur, en ce qu’on augmente une portance de la saillie cylindrique dans ledit palier et on augmente ainsi la tenue mécanique de l’adaptateur par rapport au connecteur, tout en maintenant un pivotement de l’un par rapport à l’autre. Advantage is taken of the means of rotation of the adapter, and in particular of its bearing comprising the at least three points configured to bear on the connector, in that a lift of the cylindrical projection in said bearing is increased and the mechanical strength of the adapter with respect to the connector, while maintaining a pivoting of one with respect to the other.
Selon une caractéristique de l’invention, le moyen de rotation de l’adaptateur par rapport au connecteur comprend au moins un plot cylindrique formé sur la paroi latérale opposée à celle qui porte le palier, le plot cylindrique faisant saillit vers l’espace de réception en étant aligné avec le palier le long de l’axe de rotation. According to one characteristic of the invention, the means for rotating the adapter relative to the connector comprises at least one cylindrical stud formed on the side wall opposite to that which carries the bearing, the cylindrical stud projecting towards the reception space being aligned with the bearing along the axis of rotation.
Le connecteur comprend alors un logement circulaire apte à coopérer avec le plot cylindrique du moyen de rotation de l’adaptateur et est donc destiné à être aligné le long de cet axe de rotation. The connector then comprises a circular housing capable of cooperating with the cylindrical stud of the adapter rotation means and is therefore intended to be aligned along this axis of rotation.
Selon une caractéristique de l’invention, le palier comprend au moins cinq points configurés pour prendre appui sur le connecteur, trois points parmi les cinq points étant disposés dans un premier demi-cercle du palier, et les deux autres points étant disposés dans un deuxième demi-cercle du palier. According to one characteristic of the invention, the bearing comprises at least five points configured to bear on the connector, three points among the five points being arranged in a first semicircle of the bearing, and the other two points being arranged in a second half-circle of the landing.
Le premier demi-cercle et le deuxième demi-cercle sont complémentaires l’un par rapport à l’autre et ne se superposent pas, de telle sorte qu’ils forment un cercle dans lequel s’inscrit le palier. On permet ainsi une répartition optimale des points pour maintenir au moins la saillie cylindrique du connecteur dans le palier du moyen de rotation. The first semi-circle and the second semi-circle are complementary to each other and do not overlap, so that they form a circle in which the landing is inscribed. This allows an optimal distribution of points to maintain at least the cylindrical projection of the connector in the bearing of the rotation means.
Selon une caractéristique de l’invention, le moyen de rotation comprend au moins cinq sillons formés dans l’épaisseur d’une des parois latérales de l’adaptateur en périphérie du palier, les cinq sillons s’ouvrant sur les secteurs angulaires dépourvus de matière et délimitant trois dents du moyen de rotation distinctes les unes des autres. According to one characteristic of the invention, the rotation means comprises at least five grooves formed in the thickness of one of the side walls of the adapter on the periphery of the bearing, the five grooves opening onto the angular sectors devoid of material and delimiting three teeth of the rotation means distinct from each other.
On comprend que les sillons sont ménagés dans la paroi de l’adaptateur dans laquelle est ménagé le palier.It is understood that the grooves are made in the wall of the adapter in which the bearing is made.
On comprends que les au moins 3 dents sont formées par les extrémités des dents délimitant la zone de réception du palier. It is understood that the at least 3 teeth are formed by the ends of the teeth delimiting the reception zone of the bearing.
On entend par sillon, un dégagement dans une matière de l’adaptateur, ménagé autour du palier, de telle sorte que lesdits sillons bordent les dents précitées. Par exemple, les sillons s’étendent selon des directions parallèles. Par exemple, les sillons s’étendent radialement par rapport l’axe de rotation. Selon un exemple de l’invention, deux des sillons sont formés en périphérie du palier, au niveau du premier demi-cercle tandis que trois autres sillons sont formés en périphérie du palier au niveau de son deuxième demi-cercle. On comprend alors qu’une première dent s’étend en périphérie du palier, au niveau de son premier demi-cercle tandis qu’une deuxième dent et une troisième dent s’étendent en périphérie du palier au niveau de son deuxième demi-cercle. By groove is meant a clearance in a material of the adapter, made around the bearing, so that said grooves border the aforementioned teeth. For example, the furrows extend in parallel directions. For example, the grooves extend radially from the axis of rotation. According to an example of the invention, two of the grooves are formed on the periphery of the bearing, at the level of the first semicircle, while three other grooves are formed on the periphery of the bearing at the level of its second semicircle. It is then understood that a first tooth extends on the periphery of the bearing, at the level of its first semicircle, while a second tooth and a third tooth extend on the periphery of the bearing at the level of its second semicircle.
Selon un exemple de l’invention, chacun des sillons du moyen de rotation s’ouvre sur le palier au niveau d’un des secteurs angulaires du moyen de rotation. According to an example of the invention, each of the grooves of the rotation means opens onto the bearing at the level of one of the angular sectors of the rotation means.
Selon une caractéristique de l’invention, chacune des dents comprend au moins une face d’extrémité libre tournée vers le palier du moyen de rotation, chacune des faces d’extrémité libres formant un des points du moyen de rotation de l’adaptateur destiné à prendre appui sur le connecteur. According to one characteristic of the invention, each of the teeth comprises at least one free end face facing the bearing of the rotation means, each of the free end faces forming one of the points of the rotation means of the adapter intended to lean on the connector.
On comprend alors que la face d’extrémité libre de la première dent forme un des points du moyen de rotation localisé dans le premier demi-cercle du palier tandis que les faces d’extrémités libres de la deuxième dent et de la troisième dent forment chacune un des points du moyen de rotation localisé dans le deuxième demi-cercle du palier. It is then understood that the free end face of the first tooth forms one of the points of the rotation means located in the first semicircle of the bearing while the free end faces of the second tooth and of the third tooth each form one of the points of the means of rotation located in the second semi-circle of the bearing.
Selon une caractéristique de l’invention, au moins un des sillons du moyen de rotation s’étend le long d’une droite, au moins une des dents s’étendant le long de la même droite.According to one characteristic of the invention, at least one of the grooves of the rotation means extends along a straight line, at least one of the teeth extending along the same straight line.
Selon un exemple de l’invention, chacune des dents s’étend le long d’une droite commune avec l’un des sillons du moyen de rotation.According to an example of the invention, each of the teeth extends along a common straight line with one of the grooves of the rotation means.
Selon une caractéristique de l’invention, les dents du moyen de rotation s’étendent suivant une direction d’allongement principal parallèle à une direction d’insertion du connecteur dans l’espace de réception de l’adaptateur. According to one characteristic of the invention, the teeth of the rotation means extend along a direction of main elongation parallel to a direction of insertion of the connector into the space for receiving the adapter.
Selon une caractéristique de l’invention, au moins un des sillons du moyen de rotation s’ouvre sur un bord extérieur de la paroi latérale de l’adaptateur. According to a characteristic of the invention, at least one of the grooves of the rotation means opens on an outer edge of the side wall of the adapter.
Selon un exemple de l’invention, l’ensemble des sillons du moyen de rotation s’ouvre sur un bord extérieur de la paroi latérale de l’adaptateur. De manière plus précise, deux des sillons qui s’étendent dans le premier demi-cercle du palier s’ouvrent sur un premier bord extérieur de la paroi latérale et les trois sillons qui s’étendent dans le deuxième demi-cercle du palier s’ouvrent sur un deuxième bord extérieur de la paroi latérale, opposé au premier bord extérieur selon une direction verticale de l’adaptateur. According to an example of the invention, all of the grooves of the rotation means open onto an outer edge of the side wall of the adapter. More specifically, two of the grooves which extend into the first semi-circle of the bearing open onto a first outer edge of the side wall and the three grooves which extend into the second semi-circle of the bearing open onto a second outer edge of the side wall, opposite the first outer edge in a vertical direction of the adapter.
Selon une caractéristique de l’invention, au moins une des dents comprend un chanfrein destiné à faciliter l’insertion de l’adaptateur sur le connecteur. According to a characteristic of the invention, at least one of the teeth comprises a chamfer intended to facilitate the insertion of the adapter on the connector.
On comprend de ce qui précède, que le chanfrein est formé sur au moins une des dents, à l’opposé de la face d’extrémité libre de ladite dent. De la sorte, on comprend que le chanfrein est formé au niveau du deuxième bord extérieur de la paroi latérale constitutive de l’adaptateur. It is understood from the above that the chamfer is formed on at least one of the teeth, opposite the free end face of said tooth. In this way, it is understood that the chamfer is formed at the level of the second outer edge of the side wall constituting the adapter.
L’invention vise également un ensemble constitué d’un connecteur destiné à être rendu solidaire d’un balai d’essuyage et d’un adaptateur tel que décrit dans le présent document, le connecteur et l’adapteur étant montés pivotants l’un par rapport à l’autre à l’aide du palier du moyen de rotation évoqué plus haut.The invention also relates to an assembly consisting of a connector intended to be made integral with a wiper blade and an adapter as described in the present document, the connector and the adapter being pivotally mounted one by relative to the other using the bearing of the rotation means mentioned above.
L’invention porte encore sur un balai d’essuyage comprenant au moins une lame d’essuyage, un connecteur et un adapteur selon les caractéristiques précédentes, la lame étant portée par le connecteur, le connecteur étant monté pivotant par rapport à l’adaptateur. The invention also relates to a wiper blade comprising at least one wiper blade, a connector and an adapter according to the preceding characteristics, the blade being carried by the connector, the connector being pivotally mounted with respect to the adapter.
Selon un exemple de l’invention, la lame du balai d’essuyage est portée indirectement par le connecteur, notamment par un support allongé en matière synthétique ou par une ou plusieurs vertèbres logées dans la lame d’essuyage. According to an example of the invention, the blade of the wiper blade is carried indirectly by the connector, in particular by an elongated support made of synthetic material or by one or more vertebrae housed in the wiper blade.
L’invention porte par ailleurs sur un système d’essuyage pour véhicule automobile, qui comprend un balai d’essuyage selon la caractéristique précédente et un bras relié au balai d’essuyage par l’adaptateur selon les caractéristiques précédentes. The invention also relates to a wiper system for a motor vehicle, which comprises a wiper blade according to the preceding characteristic and an arm connected to the wiper blade by the adapter according to the preceding characteristics.

La illustre un système d’essuyage 1 selon l’invention. Tel que représenté, ce système d’essuyage 1 comprend au moins un balai d’essuyage 2 et au moins un bras 4 reliés l’un à l’autre par au moins un adaptateur 6 selon l’invention. De manière plus précise, l’adaptateur 6 permet de relier un connecteur 8 qui porte le balai d’essuyage 2, ce dernier comprenant une lame 10, au bras 4 d’essuie-glace. The illustrates a wiping system 1 according to the invention. As shown, this wiper system 1 comprises at least one wiper blade 2 and at least one arm 4 connected to each other by at least one adapter 6 according to the invention. More specifically, the adapter 6 makes it possible to connect a connector 8 which carries the wiper blade 2, the latter comprising a blade 10, to the arm 4 of the windscreen wiper.
La lame 10 du balai d’essuyage 2 est adaptée pour venir au contact d’une surface vitrée d’un véhicule, non visible, équipé du système d’essuyage 1 selon l’invention. Selon un exemple de l’invention, le balai d’essuyage 2 peut comprendre au moins un organe de rigidification, par exemple un support allongé en matière synthétique ou une ou plusieurs vertèbres métalliques, et au moins un déflecteur d’air 12. On entend alors par déflecteur d’air 12, le fait que ce dernier est configuré pour transformer une pression appliquée par un flux d’air circulant le long de la surface vitrée en une force d’appui du balai d’essuyage 2 contre la surface vitrée du véhicule. The blade 10 of the wiper blade 2 is adapted to come into contact with a glazed surface of a vehicle, not visible, equipped with the wiping system 1 according to the invention. According to an example of the invention, the wiper blade 2 may comprise at least one stiffening member, for example an elongated support made of synthetic material or one or more metal vertebrae, and at least one air deflector 12. then by air deflector 12, the fact that the latter is configured to transform a pressure applied by a flow of air circulating along the glazed surface into a bearing force of the wiper blade 2 against the glazed surface of the vehicle.
Le bras 4 d’essuie-glace est quant à lui configuré pour entrainer en rotation le balai d’essuyage 2. Ainsi, le bras 4 comprend au moins une première extrémité 14 solidarisée à l’adaptateur 6 et une deuxième extrémité 16 opposée à la première extrémité 14 selon une direction d’allongement principal P du bras 4, la deuxième extrémité 16 étant solidaire d’un moteur d’entrainement, non visible, logé au sein du véhicule automobile. The wiper arm 4 is itself configured to drive the wiper blade 2 in rotation. Thus, the arm 4 comprises at least a first end 14 secured to the adapter 6 and a second end 16 opposite the first end 14 along a direction of main elongation P of the arm 4, the second end 16 being integral with a drive motor, not visible, housed within the motor vehicle.
L’adaptateur 6 et le connecteur 8, et notamment leur coopération vont maintenant être décrits plus en détail au moyen des figures 2 à 6. The adapter 6 and the connector 8, and in particular their cooperation will now be described in more detail by means of Figures 2 to 6.
L’adaptateur 6 s’étend selon une direction d’allongement principale longitudinale L et comprend au moins deux parois latérales 18 opposées l’une de l’autre selon une direction transversale T de l’adaptateur 6. Chaque paroi latérale 18 s’étend dans un plan L, V d’un trièdre L, V, T illustré sur chacune des figures.The adapter 6 extends along a main longitudinal elongation direction L and comprises at least two side walls 18 opposite each other along a transverse direction T of the adapter 6. Each side wall 18 extends in a plane L, V of a trihedron L, V, T illustrated in each of the figures.
Les deux parois latérales 18 participent à délimiter un espace de réception 20 du connecteur 8. Au moins un pontet 22 s’étend dans un plan L, T de l’adaptateur 6, à l’intérieur d’une volume délimité par les parois latérales 18 et une paroi supérieure 24. Le pontet 22 relie les parois latérales 18 de l’adaptateur 6. De manière plus précise, le pontet 22 participe à délimiter l’espace de réception 20 du connecteur 8, en coopération avec les parois latérales 18. The two side walls 18 participate in delimiting a reception space 20 of the connector 8. At least one bridge 22 extends in a plane L, T of the adapter 6, inside a volume delimited by the side walls 18 and an upper wall 24. The bridge 22 connects the side walls 18 of the adapter 6. More precisely, the bridge 22 participates in delimiting the reception space 20 of the connector 8, in cooperation with the side walls 18.
L’adaptateur 6 comprend également au moins une paroi supérieure 24 qui s’étend principalement dans un plan L, T de l’adaptateur 6, et sur l’intégralité d’une dimension longitudinale L dudit adaptateur 6. La paroi supérieure 24 comprend néanmoins une ouverture traversante 26, particulièrement visible à la , formée au moins au droit de l’espace de réception 20 du connecteur 8 et en regard d’une zone de réception 28 du bras d’essuie-glace. On comprend alors que l’espace de réception 20 du connecteur 8 est ouvert de part est d’autre de l’adaptateur 6 selon une direction verticale V, ces ouvertures s’inscrivant dans des plans parallèles au plan L, T. The adapter 6 also comprises at least one upper wall 24 which extends mainly in a plane L, T of the adapter 6, and over the whole of a longitudinal dimension L of said adapter 6. The upper wall 24 nevertheless comprises a through opening 26, particularly visible at the , formed at least in line with the reception space 20 of the connector 8 and facing a reception zone 28 of the wiper arm. It is then understood that the reception space 20 of the connector 8 is open on either side of the adapter 6 in a vertical direction V, these openings being inscribed in planes parallel to the plane L, T.
La zone de réception 28 du bras d’essuie-glace correspond à un espace destiné à recevoir la première extrémité du bras et cet espace est délimité par un trou d’insertion 30 dudit bras, visible à la , formé à une extrémité longitudinale de l’adapteur 6, de telle sorte que le trou d’insertion 30 débouche sur la zone de réception 28. La zone de réception 28 comprend au moins un plot de blocage 32, visible , faisant saillie de ladite zone de réception 28 suivant la direction verticale V de l’adaptateur 6, ledit plot de blocage 32 étant apte à coopérer avec un trou, non visible, réalisé dans la première extrémité du bras. Le plot de blocage 32 permet alors de bloquer les mouvements longitudinaux du bras lorsqu’il est logé dans la zone de réception 28. On comprend alors que la paroi supérieure 24 bloque les mouvements verticaux du bras et les parois latérales 18 bloquent ses mouvements transversaux. The reception area 28 of the wiper arm corresponds to a space intended to receive the first end of the arm and this space is delimited by an insertion hole 30 of said arm, visible at the , formed at a longitudinal end of the adapter 6, such that the insertion hole 30 opens onto the reception zone 28. The reception zone 28 comprises at least one blocking stud 32, visible , projecting from said reception zone 28 in the vertical direction V of the adapter 6, said blocking stud 32 being capable of cooperating with a hole, not visible, made in the first end of the arm. The blocking stud 32 then makes it possible to block the longitudinal movements of the arm when it is housed in the reception zone 28. It is then understood that the upper wall 24 blocks the vertical movements of the arm and the side walls 18 block its transverse movements.
L’adaptateur 6 comprend également au moins deux boutons 34, visible à la , qui s’étendent depuis la zone de réception 28 et qui forme une zone de préhension pour déverrouiller l’adaptateur 6 par rapport au bras. Chacun des boutons 34 est alors reliée à une unique potence 36 qui s’étend dans un plan L, T de l’adaptateur 6, le long de la zone de réception 28 et à l’opposé de la paroi supérieure 24. La potence 36 est déformable élastiquement et notamment suivant un mouvement vertical, par la préhension des boutons 34 par un utilisateur. On entend par déformable élastiquement le fait que la potence 36 est apte à se déformer, notamment suivant la direction verticale V de l’adaptateur 6, puis à revenir à son état initial sans rupture ni déformation irrémédiable de matière. On permet ainsi de désolidariser le bras d’essuie-glace, notamment en déplacement verticalement le plot de blocage 32 qui coopère avec le trou du bras.The adapter 6 also includes at least two buttons 34, visible at , which extend from the reception zone 28 and which form a gripping zone for unlocking the adapter 6 with respect to the arm. Each of the buttons 34 is then connected to a single stem 36 which extends in a plane L, T of the adapter 6, along the reception zone 28 and opposite the upper wall 24. The stem 36 is elastically deformable and in particular following a vertical movement, by gripping the buttons 34 by a user. By elastically deformable is meant the fact that the stem 36 is able to deform, in particular along the vertical direction V of the adapter 6, then to return to its initial state without breaking or irreparable deformation of material. This makes it possible to separate the wiper arm, in particular by vertically moving the blocking stud 32 which cooperates with the hole in the arm.
Au moins une zone chanfreinée 38, visible à la , est formée entre la paroi supérieure 24 et l’une des parois latérales 18 de l’adaptateur 6. De manière plus précise, la zone chanfreinée 38 est formée à une jointure entre la paroi supérieure 24 et l’une des parois latérales 18, et de telle sorte qu’elle forme un plan incliné par rapport à un plan principal de la paroi supérieure 24 et un plan principal de la paroi latérale 18. Une telle zone chanfreinée 38 réduit les risques de blessure en cas de choc entre un piéton et le véhicule équipé d’un adaptateur 6 selon l’invention. Selon l’exemple illustré de l’invention, une zone chanfreinée 38 similaire à celle qui vient d’être décrite est formée sur l’autre extrémité transversale de l’adaptateur 6 et de telle sorte que les deux zones chanfreinées 38 soient en regard l’une de l’autre selon la direction transversale T de l’adaptateur 6. At least one chamfered zone 38, visible at the , is formed between the upper wall 24 and one of the side walls 18 of the adapter 6. More specifically, the chamfered zone 38 is formed at a joint between the upper wall 24 and one of the side walls 18, and such that it forms an inclined plane with respect to a main plane of the upper wall 24 and a main plane of the side wall 18. Such a chamfered zone 38 reduces the risk of injury in the event of impact between a pedestrian and the vehicle equipped with an adapter 6 according to the invention. According to the illustrated example of the invention, a chamfered zone 38 similar to that which has just been described is formed on the other transverse end of the adapter 6 and in such a way that the two chamfered zones 38 face each other. from each other in the transverse direction T of the adapter 6.
L’adaptateur 6 est configuré pour être monté pivotant sur le connecteur 8, visible aux figures 1, 2 et 6, autour d’un axe de rotation R, l’axe de rotation R étant parallèle à la direction transversale T de l’adaptateur 6. A cette fin, l’adaptateur 6 comprend au moins un moyen de rotation 40 de l’adaptateur 6 par rapport au connecteur 8, formé sur les parois latérales 18 de l’adaptateur 6 et qui s’ouvrant ou qui fait saillie sur l’espace de réception 20 du connecteur 8. On définit alors une première paroi latérale 18a qui porte un palier 42 du moyen de rotation 40 et une deuxième paroi latérale 18b qui porte un plot cylindrique 44, particulièrement visible à la , faisant saillie vers l’espace de réception 20. Le palier 42 et le plot cylindrique 44 sont alors alignés le long de l’axe de rotation R. Le moyen de rotation 40 peut être formé exclusivement du palier 42, mais il peut également être formé par une combinaison du palier 42 et du le plot cylindrique 40.The adapter 6 is configured to be pivotally mounted on the connector 8, visible in Figures 1, 2 and 6, around an axis of rotation R, the axis of rotation R being parallel to the transverse direction T of the adapter 6. To this end, the adapter 6 comprises at least one means 40 for rotating the adapter 6 with respect to the connector 8, formed on the side walls 18 of the adapter 6 and which opens or which protrudes on the receiving space 20 of the connector 8. A first side wall 18a is then defined which carries a bearing 42 of the rotation means 40 and a second side wall 18b which carries a cylindrical stud 44, particularly visible to the , projecting towards the reception space 20. The bearing 42 and the cylindrical stud 44 are then aligned along the axis of rotation R. The rotation means 40 can be formed exclusively of the bearing 42, but it can also be formed by a combination of the bearing 42 and the cylindrical stud 40.
Selon une caractéristique de l’invention, le palier 42 du moyen de rotation 40, particulièrement visible à la , comprend au moins trois points 46 configurés pour prendre appui sur le connecteur, les trois points 46 étant séparés les uns des autres par des secteurs angulaires 48 dépourvus de matière. On entend alors par secteur angulaire 48, le fait que ces secteurs forment des espaces vides, dépourvu de matière et ne pouvant ainsi venir en appui contre le connecteur. Tel que visible sur l’exemple de la , le palier 42 comprend cinq secteurs angulaires 48 distincts. According to one characteristic of the invention, the bearing 42 of the rotation means 40, particularly visible at the , comprises at least three points 46 configured to rest on the connector, the three points 46 being separated from each other by angular sectors 48 devoid of material. The term “angular sector 48” is then understood to mean that these sectors form empty spaces, devoid of material and thus unable to bear against the connector. As seen in the example of the , the bearing 42 comprises five distinct angular sectors 48.
Selon l’exemple illustré sur la , le palier 42 comprend cinq points 46 distincts. Ces cinq points 46 du palier 42 sont configurés pour prendre appui sur le connecteur 8, lesdits cinq points 46 étant séparés par les cinq secteurs angulaires 48 évoqués précédemment.According to the example shown in the , the bearing 42 comprises five distinct points 46. These five points 46 of the bearing 42 are configured to rest on the connector 8, said five points 46 being separated by the five angular sectors 48 mentioned previously.
Le palier 42 du moyen de rotation 40 présentant une forme de cercle de centre C, on définit un premier demi-cercle 50a et un deuxième demi-cercle 50b, vus dans un plan L, V. Ces demi-cercles 50a et 50b sont illustrés en trait pointillés sur la . On comprend alors que le premier demi-cercle 50a et le deuxième demi-cercle 50b sont distincts l’un de l’autre, c’est-à-dire qu’ils ne se superposent pas, et sont complémentaires l’un de l’autre de telle sorte qu’ils forment le cercle de centre C dans lequel s’inscrit le palier 42. Ainsi, un premier point 46a, un deuxième point 46b et un troisième point 46c parmi les cinq points 46 configurés pour prendre appui sur le connecteur, sont disposés sur le premier demi-cercle 50a, et un quatrième point 46d et un cinquième point 46e parmi les cinq points 46 sont disposés sur le deuxième demi-cercle 50b. The bearing 42 of the rotation means 40 having the shape of a circle with center C, a first semicircle 50a and a second semicircle 50b are defined, seen in a plane L, V. These semicircles 50a and 50b are illustrated in dotted lines on the . It is then understood that the first semicircle 50a and the second semicircle 50b are distinct from each other, that is to say that they do not overlap, and are complementary to one another. other so that they form the circle with center C in which the bearing 42 fits. Thus, a first point 46a, a second point 46b and a third point 46c among the five points 46 configured to rest on the connector, are arranged on the first semi-circle 50a, and a fourth point 46d and a fifth point 46e among the five points 46 are arranged on the second semi-circle 50b.
Le moyen de rotation 40 comprend par ailleurs au moins cinq sillons 52 distincts, formés dans l’épaisseur de la première paroi latérale 18a, en en s’étendant radialement vers l’extérieur du palier 42. Un secteur angulaire 48 dépourvu de matière borde le sillons 52 qui lui est associé. C’est pourquoi le moyen de rotation 40 comprend cinq sillons 52 et cinq sillons. De manière plus précise, on définit un premier sillon 52a et un deuxième sillon 52b qui s’étendent chacun depuis l’un des secteurs angulaires 48 du palier 42 dépourvus de matière et localisés dans le premier demi-cercle 50a, et un troisième sillon 52c, un quatrième sillon 52d et cinquième sillon 52e qui s’étendent chacun depuis un des secteurs angulaires 48 du palier 42 dépourvus de matière et localisés dans le deuxième demi-cercle 50b dudit palier 42. The rotation means 40 also comprises at least five distinct grooves 52, formed in the thickness of the first side wall 18a, extending radially outwards from the bearing 42. An angular sector 48 devoid of material borders the furrows 52 associated with it. This is why the rotation means 40 comprises five grooves 52 and five grooves. More specifically, a first groove 52a and a second groove 52b are defined, each extending from one of the angular sectors 48 of the bearing 42 devoid of material and located in the first semi-circle 50a, and a third groove 52c , a fourth groove 52d and fifth groove 52e which each extend from one of the angular sectors 48 of the bearing 42 devoid of material and located in the second semicircle 50b of said bearing 42.
Selon l’exemple de réalisation de l’invention, au moins l’un des sillons 52 du moyen de rotation 40 s’ouvre sur un bord extérieur 54 de la première paroi latérale 18 de l’adaptateur 6. On définit alors un premier bord extérieur 54a de la première paroi latérale 18a, tourné vers la paroi supérieure 24 de l’adaptateur 6, et un deuxième bord extérieur 54b de la première paroi latérale 18a, opposé au premier bord extérieur 54a selon la direction verticale V de l’adaptateur 6. Ainsi, et selon l’exemple de réalisation de l’invention, le premier sillon 52a et le deuxième sillon 52b du moyen de rotation 40 s’étendent depuis le palier 42 et s’ouvrent sur le premier bord extérieur 54a de la première paroi latérale 18a, tandis que le troisième sillon 52c, le quatrième sillon 52d et le cinquième sillon 52e s’étendent depuis le palier 42 et s’ouvrent sur le deuxième bord extérieur 54b de la première paroi latérale 18a. Par ailleurs, chacun des sillons 52 du moyen de rotation 40 s’étend principalement selon la direction verticale V de l’adaptateur 6. Une telle organisation facilite le démoulage de l’adaptateur 6 pendant son processus de fabrication.According to the exemplary embodiment of the invention, at least one of the grooves 52 of the rotation means 40 opens onto an outer edge 54 of the first side wall 18 of the adapter 6. A first edge is then defined exterior 54a of the first side wall 18a, facing the upper wall 24 of the adapter 6, and a second exterior edge 54b of the first side wall 18a, opposite the first exterior edge 54a in the vertical direction V of the adapter 6 Thus, and according to the embodiment of the invention, the first groove 52a and the second groove 52b of the rotation means 40 extend from the bearing 42 and open onto the first outer edge 54a of the first wall 18a, while the third groove 52c, the fourth groove 52d and the fifth groove 52e extend from the bearing 42 and open on the second outer edge 54b of the first side wall 18a. Furthermore, each of the grooves 52 of the rotation means 40 extends mainly in the vertical direction V of the adapter 6. Such an organization facilitates the demolding of the adapter 6 during its manufacturing process.
Tel que visible sur la , les cinq sillons 52 délimitent trois dents 56 distinctes les unes des autres. De manière plus précise, le premier sillon 52a et le deuxième sillon 52b délimitent une première dent 56a qui s’étend depuis le palier 42 et jusqu’au premier bord extérieur 54a de la première paroi latérale 18a, et le troisième sillon 52c, quatrième sillon 52d et cinquième sillon 52e délimitent une deuxième dent 56b et une troisième dent 56c, distinctes l’une de l’autre et qui s’étendent depuis le palier 42 jusqu’au deuxième bord extérieur 54b de la première paroi latérale 18a. As seen on the , the five furrows 52 delimit three teeth 56 distinct from each other. More specifically, the first groove 52a and the second groove 52b delimit a first tooth 56a which extends from the bearing 42 and up to the first outer edge 54a of the first side wall 18a, and the third groove 52c, fourth groove 52d and fifth groove 52e delimit a second tooth 56b and a third tooth 56c, distinct from each other and which extend from the bearing 42 to the second outer edge 54b of the first side wall 18a.
Chacune des dents 56 du moyen de rotation 40 comprend une face d’extrémité libre 58, tournée vers le palier 42 du moyen de rotation 40, chacune des faces d’extrémité libres 58 formant un des points 46 du moyen de rotation 40 destinés à prendre appui sur le connecteur 8, tel qu’évoqués précédemment. Par ailleurs, chacune des dents 56 du moyen de rotation 40 s’étend depuis le palier 42 selon la direction verticale V de l’adaptateur 6. Each of the teeth 56 of the rotation means 40 comprises a free end face 58, facing the bearing 42 of the rotation means 40, each of the free end faces 58 forming one of the points 46 of the rotation means 40 intended to take support on the connector 8, as mentioned above. Furthermore, each of the teeth 56 of the rotation means 40 extends from the bearing 42 in the vertical direction V of the adapter 6.
Ainsi, le deuxième point 46b évoqué précédemment, compris dans le premier demi-cercle 50a, est formé au niveau de la face d’extrémité libre 58 de la première dent 56a, tandis que le premier point 46a et le troisième point 46c également compris dans le premier demi-cercle 50a, sont formés chacun par des bords périphériques 60 du palier 42, les bords périphériques 60 du palier 42 présentant notamment une forme courbée participant à délimiter le cercle dans lequel s’inscrit le palier 42. Le quatrième point 46d et le cinquième point 46e qui s’inscrivent dans le deuxième demi-cercle 50b sont eux respectivement formés au niveau de la face d’extrémité libre 58 de la deuxième dent 56b et de la troisième dent 56c. Thus, the second point 46b mentioned above, included in the first semi-circle 50a, is formed at the level of the free end face 58 of the first tooth 56a, while the first point 46a and the third point 46c also included in the first semi-circle 50a, are each formed by peripheral edges 60 of the bearing 42, the peripheral edges 60 of the bearing 42 having in particular a curved shape participating in delimiting the circle in which the bearing 42 is inscribed. The fourth point 46d and the fifth point 46e which fit into the second semi-circle 50b are respectively formed at the level of the free end face 58 of the second tooth 56b and of the third tooth 56c.
Selon une caractéristique de l’invention, au moins un des sillons 52 du moyen de rotation 40 s’étend le long d’une droite, et au moins une des dents 56 s’étend le long de cette même droite. De manière plus précise et selon l’exemple de l’invention illustré, le premier sillon 52a s’étend le long d’une première droite verticale D1 commune avec la deuxième dent 56b, le deuxième sillon 52b s’étend le long d’une deuxième droite verticale D2 commune avec la troisième dent 56c et le quatrième sillon 52d s’étend le long d’une troisième droite verticale D3 commune avec la première dent 56a. According to one characteristic of the invention, at least one of the grooves 52 of the rotation means 40 extends along a straight line, and at least one of the teeth 56 extends along this same straight line. More precisely and according to the example of the invention illustrated, the first groove 52a extends along a first vertical straight line D1 common with the second tooth 56b, the second groove 52b extends along a second vertical line D2 common with the third tooth 56c and the fourth groove 52d extends along a third vertical line D3 common with the first tooth 56a.
D’une manière générale, les dents 56 sont disposées en alternance le long de la direction longitudinale L. Il en va de même pour les sillons 52 qui sont eux aussi disposés de manière alternée en se déplaçant le long de la direction longitudinale L. In general, the teeth 56 are arranged alternately along the longitudinal direction L. The same applies to the grooves 52 which are also arranged alternately by moving along the longitudinal direction L.
Selon l’invention, au moins une des dents 56 du palier 42 comprend un chanfrein 62 destiné à faciliter l’insertion de l’adaptateur 6 sur le connecteur 8. De manière plus précise et selon l’exemple illustré, la deuxième dent 56b et la troisième dent 56c comprennent chacune un chanfrein 62 formé à l’opposé de leurs faces d’extrémité libres 58, de telle sorte qu’ils facilitent l’insertion de l’adaptateur 6 sur le connecteur 8. According to the invention, at least one of the teeth 56 of the bearing 42 comprises a chamfer 62 intended to facilitate the insertion of the adapter 6 on the connector 8. More precisely and according to the example illustrated, the second tooth 56b and the third tooth 56c each include a chamfer 62 formed opposite their free end faces 58, so that they facilitate the insertion of the adapter 6 on the connector 8.
Tel que cela est visible à la , le plot cylindrique 44 comprend un bord d’attaque 45 chanfreiné, tourné à l’opposé de la paroi supérieure 24. On comprend donc que le bord d’attaque 45 est formé sur le plot cylindrique 44 de telle sorte qu’il facilite l’insertion de l’adaptateur 6 sur le connecteur.As seen at the , the cylindrical stud 44 comprises a chamfered leading edge 45, facing away from the upper wall 24. It is therefore understood that the leading edge 45 is formed on the cylindrical stud 44 in such a way that it facilitates the insertion of the adapter 6 on the connector.
Le connecteur 8 particulièrement visible à la , comprend au moins une première portion 68 de fixation au balai d’essuyage, la première portion 68 de fixation formant notamment un moyen d’attachement de la lame du balai d’essuyage entre une première patte 70a et une deuxième patte 70b de la première portion 68. Le connecteur 8 comprend par ailleurs une deuxième portion 72 de fixation avec l’adapteur 6 qui s’étend verticalement depuis la première portion 68, à l’opposé de la première patte 70a et de la deuxième patte 70b de la première portion 68. Connector 8 particularly visible at the , comprises at least a first portion 68 for attachment to the wiper blade, the first attachment portion 68 forming in particular a means for attaching the blade of the wiper blade between a first tab 70a and a second tab 70b of the first portion 68. The connector 8 also comprises a second portion 72 for fixing with the adapter 6 which extends vertically from the first portion 68, opposite the first tab 70a and the second tab 70b of the first portion 68.
La deuxième portion 72 du connecteur 8 comprend le logement circulaire 66 formant un renfoncement cylindrique dans la matière de la deuxième portion 72. De manière plus précise, le logement circulaire 66 est formé dans la deuxième portion 72 du connecteur 8 de telle sorte qu’il soit apte à coopérer avec le plot cylindrique de l’adaptateur 6, suivant l’axe de rotation R. La deuxième portion 72 du connecteur 8 comprend également un toron cylindrique 74 formant en saillie de ladite deuxième portion 72 et à l’opposé du volume de cette dernière, de telle sorte que le toron cylindrique 74 soit apte à coopérer avec le palier 42 du moyen de rotation 40 de l’adaptateur 6 selon l’axe de rotation R. On comprend alors que le toron cylindrique 74 est destinée à être en appui sur les au moins trois points d’appui du palier 42, voire les cinq points du palier 42 du moyen de rotation 40 de l’adaptateur 6 décrit ci-dessus. The second portion 72 of the connector 8 comprises the circular housing 66 forming a cylindrical recess in the material of the second portion 72. More precisely, the circular housing 66 is formed in the second portion 72 of the connector 8 in such a way that it is capable of cooperating with the cylindrical stud of the adapter 6, along the axis of rotation R. The second portion 72 of the connector 8 also comprises a cylindrical strand 74 projecting from said second portion 72 and opposite the volume of the latter, so that the cylindrical strand 74 is capable of cooperating with the bearing 42 of the means of rotation 40 of the adapter 6 along the axis of rotation R. It is then understood that the cylindrical strand 74 is intended to be resting on the at least three points of support of the bearing 42, or even the five points of the bearing 42 of the means of rotation 40 of the adapter 6 described above.
Un procédé d’assemblage de l’adaptateur 6 sur le connecteur 8 va maintenant être décrit au moyen des figures 4 à 6. A method of assembling the adapter 6 on the connector 8 will now be described by means of figures 4 to 6.
Le procédé d’assemblage comprend au moins une première étape au cours de laquelle on positionne le connecteur 8 en regard de l’espace de réception 20 de l’adaptateur 6 et de telle sorte que le deuxième bord extérieur 54b de la première paroi latérale 18a soit tourné vers ledit connecteur 8. A une deuxième étape, on dispose l’adaptateur 6 sur le connecteur 8 de telle sorte que au moins une partie du connecteur 8 soit logé dans l’espace de réception 20 de l’adaptateur 6. De manière plus précise, on translate l’adaptateur 6 sur le connecteur 8 suivant la direction verticale V dudit adaptateur 6, de telle sorte que la deuxième portion 72 du connecteur 8 rencontre les chanfreins 62 ménagés sur la deuxième dent 56b et sur la troisième dent 56c du moyen de rotation 40. The assembly method comprises at least a first step during which the connector 8 is positioned facing the reception space 20 of the adapter 6 and in such a way that the second outer edge 54b of the first side wall 18a is turned towards said connector 8. In a second step, the adapter 6 is arranged on the connector 8 in such a way that at least part of the connector 8 is housed in the reception space 20 of the adapter 6. In such a way more precisely, the adapter 6 is translated onto the connector 8 in the vertical direction V of said adapter 6, so that the second portion 72 of the connector 8 meets the chamfers 62 provided on the second tooth 56b and on the third tooth 56c of the means of rotation 40.
On poursuit alors l’insertion de la deuxième portion 72 du connecteur 8 suivant le mouvement de translation verticale, de telle sorte que la deuxième portion 72 dudit connecteur 8 rencontre le bord d’attaque 45 du plot cylindrique 44. Enfin, le toron cylindrique 74 se loge dans le palier 42 du moyen de rotation 40 selon l’invention et le logement circulaire 66 accueille le plot cylindrique 44 du moyen de rotation 40 de l’adaptateur 6. The insertion of the second portion 72 of the connector 8 is then continued following the vertical translation movement, so that the second portion 72 of the said connector 8 meets the leading edge 45 of the cylindrical stud 44. Finally, the cylindrical strand 74 is housed in the bearing 42 of the rotation means 40 according to the invention and the circular housing 66 accommodates the cylindrical stud 44 of the rotation means 40 of the adapter 6.
On comprend alors qu’à l’issus du procédé d’assemblage, le moyen de rotation 40 de l’adaptateur 6, comprenant au moins le palier 42 et le plot cylindrique 44, ainsi que le toron cylindrique 74 et le logement circulaire 66 du connecteur 8, sont alignés le long de l’axe de rotation R de l’adaptateur 6 par rapport audit connecteur 8.It is then understood that at the end of the assembly process, the means of rotation 40 of the adapter 6, comprising at least the bearing 42 and the cylindrical stud 44, as well as the cylindrical strand 74 and the circular housing 66 of the connector 8, are aligned along the axis of rotation R of the adapter 6 with respect to said connector 8.
On tire alors avantage de l’adaptateur tel qu’il vient d’être décrit en ce que son moyen de rotation, et notamment son palier comprenant les au moins trois points configurés pour prendre appui sur le connecteur, augmentent la tenue mécanique de l’adaptateur sur le connecteur. On tire également avantage d’une telle invention en ce qu’il est possible d’obtenir le palier comprenant les au moins trois points d’appui par des moyens simples, ne complexifiant pas les moyens de production déjà existants. Advantage is then taken of the adapter as it has just been described in that its means of rotation, and in particular its bearing comprising the at least three points configured to bear on the connector, increase the mechanical strength of the adapter on the connector. Advantage is also taken from such an invention in that it is possible to obtain the bearing comprising the at least three support points by simple means, not complicating the already existing means of production.
L’invention telle qu’elle vient d’être décrite ne saurait toutefois se limiter aux moyens et configurations exclusivement décrits et illustrés, et s’applique également à tous moyens ou configurations, équivalents et à toute combinaison de tels moyens ou configurations.The invention as it has just been described cannot however be limited to the means and configurations exclusively described and illustrated, and also applies to all means or configurations, equivalents and to any combination of such means or configurations.
