Description

La présente invention est relative à un balai d'essuie- glace en matière plastique comprenant un pont principal et deux ponts se condaires connectes aux deux extrémités du pont principal. De tels balais d'essuie-glace sont par exemple utilisés sur les véhicules à moteur. The present invention relates to a plastic wiper blade comprising a main bridge and two fixed bridges connected to the two ends of the main bridge. Such wiper blades are for example used on motor vehicles.

L'objet de l'invention est la réalisation d'un balai d'essuie-glace du type défini ci-dessus, dans lequel la connexion entre le pont principal et les ponts secondaires est très simple et très fonctionnelle, dans lequel aucune pièce supplémentaire de connexion n'est nécessaire et dont l'assemblage est facile et rapide, réduisant ainsi les coûts de fabrication. The object of the invention is the production of a wiper blade of the type defined above, in which the connection between the main deck and the secondary decks is very simple and very functional, in which no additional part connection is not necessary and the assembly is easy and quick, thus reducing manufacturing costs.

Pour arriver au résultat ainsi défini le balai d'essuieglace selon l'invention est essentiellement caractérisé par le fait que chaque pont secondaire est pourvu d'une ouverture dans laquelle s'étend un pivot transversel et que le pont principal est pourvu à ses deux extrémies d'une fourche élastique s'étendant vers le bas dans ladite ouverture du pont secondaire correspondant, le fond de ladite fourche ayant une surface cylindrique d'une amplitude de plus de 1800 et constituant un siège transversal pouvant recevoir par encliquetage le pivot transversal du pont secondaire. To achieve the result thus defined, the wiper blade according to the invention is essentially characterized in that each secondary bridge is provided with an opening in which a transverse pivot extends and that the main bridge is provided at its two ends. of an elastic fork extending downward into said opening of the corresponding secondary bridge, the bottom of said fork having a cylindrical surface of an amplitude of more than 1800 and constituting a transverse seat which can receive by snap-fastening the transverse pivot of the bridge secondary.

A cause de ces caractéristiques le balai d'essuie-glace selon l'invention n'a pas seulement l'avantage qu'il peut etre fabriqué et assemblé d'une manière simple et économique, mais aussi qu'il ne comporte pas de protubérances dans les deux zones de connexion entre le pont principal et les ponts secondaires, évitant ainsi toute possibilité de blessure par lesdites protubérances. Because of these characteristics, the wiper blade according to the invention not only has the advantage that it can be manufactured and assembled in a simple and economical manner, but also that it does not have protuberances. in the two connection zones between the main bridge and the secondary bridges, thus avoiding any possibility of injury by said protuberances.

D'après une autre caractéristique de l'invention le pont principal a, du moins à proximité de ses deux extrémités, une sectiOn transversale ayant la forme d'un U renversé et chaque pont secondai re est pourvu à sa partie supérieure, entre ladite ouverture et son extrémité interne, d'une nervure capable de s'insérer dans la cavité lon gitudinale correspondante de la partie en forme de U du pont principal
Cette caractéristique augmente la résistance généra- le du balai d'essuie-glace et diminue substantiellement le jeu latéral entre les ponts secondaires et le pont principal, améliorant ainsi l'ef- ficacité du balai.According to another characteristic of the invention, the main bridge has, at least near its two ends, a transverse section having the shape of an inverted U and each secondary bridge is provided at its upper part, between said opening. and its internal end, of a rib capable of fitting into the corresponding longitudinal groove of the U-shaped part of the main bridge
This characteristic increases the general resistance of the wiper blade and substantially reduces the lateral play between the secondary bridges and the main bridge, thereby improving the efficiency of the blade.

D'autres catactéristiques de l'invention seront mieux comprises à la lecture de la description ci-après en se référant aux dessins annexés dans lesquels: - la figure 1 est une vue en élévation du balai d'essuie-glace selon 1'
invention, les différentes parties le composant étant assemblées; - la figure 2 est une vue similaire à celle de la figure 1 le balai d'es

Sur la figure 1 le numéro de référence 10 désigne un balai d'essuie-glace pourvu d'une superstructure en matière plastique 12 selon l'invention. Cette superstructure 12 comprend un pont principal 14 et deux ponts secondaires 16. Une lame élastique 18 portant une raclette en caoutchouc 20 est attachée aux ponts secondaires 16. In Figure 1 the reference number 10 designates a wiper blade provided with a plastic superstructure 12 according to the invention. This superstructure 12 comprises a main bridge 14 and two secondary bridges 16. An elastic blade 18 carrying a rubber squeegee 20 is attached to the secondary bridges 16.

Comme montré sur les figures 2 et 3 le pont principal 14 a une section transversale ayant sensiblement la forme d'un U renversé. Dans la partie centrale 24 du pont principal 14 une ouverture sensiblement rectangulaire 26 a été ménagée. Un pivot transversal 28 et une entretoise longitudinale de renforcement 30 s'étendent à l'intérieur de ladite ouverture 25. Le pivot 28 sert à y attacher un connecteur 32 capable de recevoir un bras d'essuie-glace (non représenté). Le connecteur 32 comprend une partie élastique en forme de fourche 34 qui peut etre fixée sur le pivot 28 par encliqetage.  As shown in Figures 2 and 3 the main deck 14 has a cross section having substantially the shape of an inverted U. In the central part 24 of the main deck 14 a substantially rectangular opening 26 has been made. A transverse pivot 28 and a longitudinal reinforcing spacer 30 extend inside said opening 25. The pivot 28 serves to attach a connector 32 capable of receiving a wiper arm (not shown). The connector 32 comprises a resilient fork-shaped part 34 which can be fixed to the pivot 28 by snap-fastening.

A chacune de ses deux extrémités le pont principal 14
est pourvu d'une fourche 36 dirigée vers le bas, c'est-à-dire vers le
pont secondaire correspondant 16. Chaque fourche 36 comprend. une branche
externe 38 et deux branches internes 40, les branches internes étant sé
parées par une fente 42. Les surfaces inférieures internes des branches
38, 40 de la fourche 36 convergent vers le haut de façon a forer une
ouverture trapéz & ale 44 dans le siège transversal 46 détermine par le
fond de la fourche 36 et ayant une surface cylindrique d'une amplitude
supérieure à 1800.At each of its two ends, the main deck 14
is provided with a fork 36 directed downwards, that is to say towards the
corresponding secondary bridge 16. Each fork 36 includes. a branch
external 38 and two internal branches 40, the internal branches being dried
trimmed by a slot 42. The inner lower surfaces of the branches
38, 40 of the fork 36 converge upwards so as to drill a
trapezoidal opening 44 in the transverse seat 46 determined by the
bottom of the fork 36 and having a cylindrical surface of an amplitude
greater than 1800.

Chaque face interne des deux flancs 14a du pont prin cipal 14 est pourvoe,près des fourches 36, d'une pluralité de nervures opposées 48. La fonction de ces nervures 48 sera expliquée ultérieurement. Each internal face of the two sides 14a of the main bridge 14 is provided, near the forks 36, with a plurality of opposite ribs 48. The function of these ribs 48 will be explained later.

Sur les figures 2 et 4 on peut voir qu'a sa surface supérieure 16a chaque pont secondaire 16 est pourvu d'une ouverture 50 définie par deux parois latérales 52 entre lesquelles s'étend un pivot transversal 54 relié a un entretoise 56 s'étendant vers le bas, c' est-à-dire vers la raclette en caoutchouc 20. In Figures 2 and 4 we can see that at its upper surface 16a each secondary bridge 16 is provided with an opening 50 defined by two side walls 52 between which extends a transverse pivot 54 connected to a spacer 56 extending downwards, that is to say towards the rubber scraper 20.

Chaque pont secondaire 16 est pourvu, à ses deux ex extrémités, de griffes internes 58 et externes 60 dans lesquelles est insérée une lame élastique 18 portant la raclette 20. Afin de pouvoir positionner correctement la lame 18 par rapport aux ponts secondaires 16, un arrêt 62 est pourvu a chaque extrémité externe des ponts secondaires 16. Each secondary bridge 16 is provided, at its two ex ends, with internal 58 and external 60 claws into which an elastic blade 18 carrying the squeegee 20 is inserted. In order to be able to correctly position the blade 18 relative to the secondary bridges 16, a stop 62 is provided at each external end with secondary bridges 16.

La partie de chacun des ponts secondaires 16 comprise entre l'ouverture 50 et les griffes externes 60 a une section transversale ayant sensiblement la forme d'un U renversé avec une cavité 64 dirigée vers la raclette 20. L'autre partie des ponts secondaires 16, c'est à-dire la partie comprise entre l'ouverture 50 et les griffes internes 58 est située a un niveau plus bas que le pivot 54 et est pourvue, à sa surface supérieure, d'une nervure longitudinale 66 qui est connectez, par une partie a largeur réduite 68, au pivot 54. The part of each of the secondary bridges 16 between the opening 50 and the external claws 60 has a cross section having substantially the shape of an inverted U with a cavity 64 directed towards the squeegee 20. The other part of the secondary bridges 16 , that is to say the part between the opening 50 and the internal claws 58 is situated at a lower level than the pivot 54 and is provided, at its upper surface, with a longitudinal rib 66 which is connected, by a reduced width portion 68, at pivot 54.

La première phase de l'assemblage du balai d'essuieglace 10 consiste a insérer la lame 18, portant la raclette 20, dans les griffes 58, 60 des deux ponts secondaires 16. La deuxième phase consiste à connecter le pont principal 14 aux deux ponts secondaires 16 en encliquetant les fourches 36 du pont principal 14 sur les deux pivots 54 des ponts secondaires 16. L'assemblage du balai d'essuie-glace selon l'invention est donc une opération très facile et très rapide. The first phase of the assembly of the wiper blade 10 consists in inserting the blade 18, carrying the squeegee 20, in the claws 58, 60 of the two secondary bridges 16. The second phase consists in connecting the main bridge 14 to the two bridges secondary 16 by snapping the forks 36 of the main bridge 14 on the two pivots 54 of the secondary bridges 16. The assembly of the wiper blade according to the invention is therefore a very easy and very fast operation.

Lorsque le balai d'essuie-glace selon l'invention est assemblé, les deux branches internes 40 des fourches 36 entourent les parties plus minces 68 des nervures longitudinales 66 des ponts secondaires 16. Lorsque lesdits ponts secondaires 16 tournent autour de l'axe de leurs pivots 54, les nervures 66 peuvent rentrer dans la cavité 22 du pont principal 14 et plus particulièrement dans l'espace entre lesdites nervures opposées 48 dont la fonction est d'éviter tout jeu latéral excessif entre les ponts secondaires 16 et le pont principal 14. When the wiper blade according to the invention is assembled, the two internal branches 40 of the forks 36 surround the thinner parts 68 of the longitudinal ribs 66 of the secondary bridges 16. When the said secondary bridges 16 rotate around the axis of their pivots 54, the ribs 66 can enter the cavity 22 of the main bridge 14 and more particularly in the space between said opposite ribs 48 whose function is to avoid any excessive lateral play between the secondary bridges 16 and the main bridge 14 .

Afin d'éviter tout arrachage accidentel de la lame élastique 18 des griffes externes 60 des ponts secondaires 16, dû par exemple à une traction excessive exercée sur la partie centrale de la lame 18 dans la direction opposée à la superstructure 12 pendant l'util;- sation ou pendant l'assemblage du balai, les fourches 36 et les zones de connexion correspondantes des ponts secondaires 16 peuvent être dessinées de façon à définir des surfaces d'arrêt supplémentaires capables de coopérer entre elles pour limiter la rotation des ponts secondaires 16 autour de l'axe de leurs pivots respectifs 54. In order to avoid any accidental tearing of the elastic blade 18 of the external claws 60 of the secondary bridges 16, due for example to excessive traction exerted on the central part of the blade 18 in the direction opposite to the superstructure 12 during use; - Station or during the assembly of the brush, the forks 36 and the corresponding connection areas of the secondary bridges 16 can be drawn so as to define additional stop surfaces capable of cooperating with each other to limit the rotation of the secondary bridges 16 around the axis of their respective pivots 54.

Comme montré en détail sur la figure 5, de telles surfaces d'arrêt sont définies par la surface S de la face externe de l'entretoise transversale 56 reliée au pivot 54 et par la surface interne adjacente S' de la branche 38 de la fourche 36. L'angle maximum entre les deux surfaces S, S' correspond 3 l'angle de rotation maximum des ponts secondaires 16 par rapport au pont 14
D'autres surfaces d'arret T, T' peuvent être prévues dans les zones de connexion des ponts secondaires 16. Ces surfaces d'arret correspondent respectivement à la partie externe supérieure Tde la paroi transversale externe de l'ouverture 50 et a la surface externe T' de la branche 38 de la fourche 36.As shown in detail in FIG. 5, such stop surfaces are defined by the surface S of the external face of the transverse spacer 56 connected to the pivot 54 and by the adjacent internal surface S 'of the branch 38 of the fork 36. The maximum angle between the two surfaces S, S 'corresponds to 3 the maximum angle of rotation of the secondary bridges 16 relative to the bridge 14
Other stop surfaces T, T ′ may be provided in the connection areas of the secondary bridges 16. These stop surfaces correspond respectively to the upper external part T of the external transverse wall of the opening 50 and to the surface outer T 'of branch 38 of fork 36.

De la présente description il apparait clairement que le nouveau balai d'essuie-glace selon l'invention comprend un nombre minimum de pièces essentielles, ctest-3-dire de pièces indispensables, qui peuvent etre assemblées très facilement et très rapidement sans utiliser un outil quelconque et sans utiliser des pièces de connexion intermédiaires et supplémentaires.  From the present description it is clear that the new wiper blade according to the invention comprises a minimum number of essential parts, that is to say essential parts, which can be assembled very easily and very quickly without using a tool. any and without using intermediate and additional connecting parts.

Il est évident que l'invention n'est pas limitée au mode de réalisation décrit et représenté, mais que des modifications et/ ou changements peuvent y etre apportés sans sortir du cadre de l'invention tel que défini par les revendications ci-après. Il est ainsi par exemple évident que la connexion entre le pont principal 14 et les deux ponts secondaires 16, telle que décrite ci-dessus peut aussi être utilisée pour toutes les connexions d'un balai d'essuie-glace plus complexe, comprenant par exemple un pont principal, un ou deux ponts intermédiaires et plus de deux ponts secondaires.  It is obvious that the invention is not limited to the embodiment described and shown, but that modifications and / or changes can be made thereto without departing from the scope of the invention as defined by the claims below. It is thus for example obvious that the connection between the main bridge 14 and the two secondary bridges 16, as described above can also be used for all the connections of a more complex wiper blade, comprising for example a main bridge, one or two intermediate bridges and more than two secondary bridges.
