Description

DISPOSITIF DE LIAISON ENTRE UNE LAME D'ESSUIE-GLACE ET UNE MONTURE SUPPORTDEVICE FOR CONNECTING A WIPER BLADE AND A SUPPORT MOUNT

La presente invention porte sur un dispositif de liaison entre une lame d'essuie-glace et une monture support, et s'applique plus precisement aux balais d'essuie-glace dits de type plat ou flat blade D, c'est-a-dire des balais ne presentant pas d'armature reliee aux deux extremites de la monture support, mais uniquement un point de connexion avec un bras d'entrainement au niveau de sa partie mediane.  The present invention relates to a connection device between a windscreen wiper blade and a support mount, and applies more specifically to the so-called wiper blades of flat type or flat blade D, that is to say say brooms having no armature connected to the two ends of the support frame, but only a connection point with a drive arm at its median part.

Les bras d'essuie-glace, notamment de vehicules automobiles, sont couramment constitues d'un bras d'entrainement mobile apte a deplacer un balai d'essuyage comprenant une monture support ou porte-balai et une lame d'essuyage apte a titre plaquee contre une vitre ou un parebrise.  Wiper arms, especially motor vehicles, are commonly constituted by a movable drive arm adapted to move a wiper blade comprising a support frame or brush holder and a wiper blade suitable for plate against a window or windshield.

A I'extremite du bras d'entra?nement est prevue un element de solidarisation entre la lame et le bras, appele couramment "end clip". Le probleme est de fixer cet element dit "end clip" sur la lame, par un dispositif de liaison qui soft fiable, economique, peu encombrant, et qui permette le remplacement de la lame.  At the end of the drive arm is provided a securing element between the blade and the arm, commonly called "end clip". The problem is to fix this element called "end clip" on the blade, by a connecting device that soft reliable, economic, compact, and allows the replacement of the blade.

25 Des solutions ont deja ete proposees dans ['art anterieur pour tenter d'atteindre ces buts.  Solutions have already been proposed in the prior art in an attempt to achieve these goals.

II est connu selon FR 2302888 de realiser un porte-balai a deux branches reliees au balai d'essuie-glace par I'intermediaire d'au moins un element 30 de liaison susceptible d'etre accroche de facon amovible au balai d'essuie-glace a I'aide de moyens d'encliquetage entourant Iateralement la lame du balai par des griffes.20 II est egalement connu selon FR2305324 de realiser un dispositif de liaison entre le porte balai et la lame d'essuie-glace sous la forme d'une agrafe laterale apte a accoupler la lame d'essuie-glace au porte balai. Toutefois, ces modes de realisation necessitent un element de liaison relativement complexe a fabriquer et a assembler et sont susceptibles de se decrocher. De plus, la presence d'un element de liaison sur le balai d'essuie-glace presente un aspect inesthetique. 10 Selon la demande de brevet FR2429132, it est egalement connu de realiser un dispositif de liaison entre une lame d'essuie-glace et un porte balai a ('aide d'une plaque presentant une pluralite de pattes et une patte aptes a cooperer avec la lame et la monture support. De meme, it est prevu selon DE 4325601 un dispositif de liaison entre la lame et la monture support a ('aide de moyens de pincement entourant lateralement le balai et la monture support.  It is known according to FR 2302888 to make a brush holder with two branches connected to the windscreen wiper blade by means of at least one connecting element 30 that can be removably attached to the wiper blade. by means of snap-fastening means electrically surrounding the blade of the blade by claws. It is also known according to FR2305324 to make a connection device between the blade holder and the wiper blade in the form of a lateral staple capable of coupling the wiper blade to the wiper door. However, these embodiments require a connection element relatively complex to manufacture and assemble and are likely to fall. In addition, the presence of a connecting element on the wiper blade presents an unsightly appearance. According to the patent application FR2429132, it is also known to provide a connection device between a wiper blade and a brush holder by means of a plate having a plurality of legs and a tab capable of cooperating with Also, according to DE 4325601, a connection device is provided between the blade and the support frame by means of clamping means which laterally surrounds the blade and the support frame.

20 Toutefois, ces modes de realisation sont relativement longs et complexes a mettre en oeuvre et a assembler.  However, these embodiments are relatively long and complex to implement and assemble.

Enfin, ces modes de realisation connus ne sont pas adaptes aux balais d'essuie-glace dont la monture support, sensiblement longitudinale, est 25 reliee au niveau de sa partie centrale a un bras d'entrainement.  Finally, these known embodiments are not suitable for wiper blades whose support frame, substantially longitudinal, is connected at its central portion to a drive arm.

Par ailleurs, on connait un ensemble de balai d'essuie-glace comprenant une languette parallelepipedique, plane, en matiere plastique, apte a traverser une lumiere prevue respectivement sur deux pattes later-ales 15 disposees a la base de ('element de solidarisation ("end clip"), ainsi qu'une lumiere prevue sur la lame.  Furthermore, a windscreen wiper blade assembly is known comprising a parallelepipedal, flat, plastic tongue adapted to pass through a light respectively provided on two laterally-arranged lugs 15 arranged at the base of the fastening element ( "end clip"), as well as a light provided on the blade.

Cependant, ce dispositif est susceptible d'amelioration. En effet, la languette souleve des problemes de fabrication et de distribution, d'une part, et de fiabilite d'autre part.  However, this device is susceptible of improvement. Indeed, the tongue raises problems of manufacture and distribution, on the one hand, and reliability on the other hand.

En outre, on a propose de maniere connue, de prevoir une piece metallique en materiau relativement elastique, pourvue d'elements en saillie (tels que des griffes), de maniere a realiser une sorte de sertissage sur la lame, apres assemblage de ('element de solidarisation (end clip).  In addition, it has been proposed in known manner, to provide a metal piece relatively elastic material, provided with projecting elements (such as claws), so as to achieve a kind of crimping on the blade, after assembly of (' locking element (end clip).

Neanmoins, cette solution connue presente des inconvenients. La dite piece est relativement compliquee a fabriquer. Or, la precision est importante, car le moindre defaut a des consequences sur la fiabilite de la liaison.  Nevertheless, this known solution has disadvantages. The said piece is relatively complicated to manufacture. Precision is important because the slightest defect has consequences for the reliability of the link.

A cette fin, selon ('invention, it est propose un dispositif de liaison entre un porte-balai d'essuie-glace et une lame d'essuie-glace, la lame etant constituee d'une partie superieure apte a cooperer avec le porte balai, du type comportant une paire de pattes laterales pourvues chacune d'un orifice dans lequel est apte a s'inserer et bloquer un element formant clavette. Le dispositif selon ('invention est caracterise en ce que ladite clavette presente des moyens de verrouillage.  To this end, according to the invention, it is proposed a connecting device between a windscreen wiper blade and a windscreen wiper blade, the blade being constituted of a top portion capable of cooperating with the door broom, of the type comprising a pair of lateral tabs each provided with an orifice in which is adapted to insert and block a key element The device according to the invention is characterized in that said key has locking means.

Plus precisement, la clavette est constituee d'une tige cylindrique pourvue a ('une au moins de ses extremites d'une partie en excroissance, de dimension transversale (ou axiale) superieure au diametre de la tige.  More specifically, the key is constituted by a cylindrical rod provided at least at one end with a protruding portion of transverse (or axial) dimension greater than the diameter of the rod.

Lesdites parties d'extremite sont de preference de forme cylindriques, et en outre avantageusement pourvues de crantage.  Said end portions are preferably of cylindrical shape, and further advantageously provided with notches.

Ladite clavette est realisee en un materiau metallique. Selon une variante, la lame d'essuie-glace ne comporte pas de lumiere, et la clavette est apte a former un orifice dans la lame par per-cage de la lame, lors de ('assemblage.  Said key is made of a metal material. Alternatively, the wiper blade has no light, and the key is adapted to form an orifice in the blade per-cage of the blade during assembly.

10 La presente invention est maintenant decrite a ('aide d'exemples uniquement illustratifs et nullement limitatifs de la portee de la presente invention, et a ('aide des illustrations ci-jointes dans lesquelles :  The present invention is now described by way of purely illustrative and non-limiting examples of the scope of the present invention, and with the aid of the accompanying illustrations in which:

A support mount has a wiper blade in accordance with an embodiment of the invention, and FIG. 4 is a cross-sectional view of the blade and the support mount secured and locked to one another. Another use of the locking device of the invention Fig. 1 shows a prior art embodiment comprising a wiper blade of reference numeral 1, preferably of a type known per se under the designation flat blade D, comprising a brush holder or a substantially longitudinal support mount 2. The support frame 2 is constituted by an internal vertebra 3 in the form of a longitudinal horizontal blade inserted into a tubular central body 4 of main axis substantially longitudinal delimits by an upper wall horizontally ale 5, a horizontal lower wall 6 and two vertical longitudinal side walls 7.

Dans la suite de la description, it est entendu par direction longitudinale ou direction horizontale une direction parallele a ('axe longitudinal de la lame d'essuie-glace et par direction transversale ou direction verticale une direction perpendiculaire a ('axe longitudinal de la vertebre interne et situee dans un plan confondu avec la vertebre interne 3.  In the remainder of the description, it is understood by longitudinal direction or horizontal direction a parallel direction a (longitudinal axis of the wiper blade and by transverse direction or vertical direction a direction perpendicular to (longitudinal axis of the vertebra internal and located in a plane confused with the internal vertebra 3.

Des moyens de connexion 8 sont prevus pour connecter le balai d'essuie-glace 1 a un bras d'entrainement (non represents sur la figure mais de type connu en soi).  Connecting means 8 are provided for connecting the wiper blade 1 to a drive arm (not shown in the figure but of known type).

II est prevu sur la surface externe de la paroi superieure 5 du corps central 4 une nervure superieure 9 dirigee verticalement de maniere ascendante. 20 De maniere complementaire, la nervure superieure 9 est conformee de maniere a produire des forces d'appui du balai d'essuieglace 1 sur la surface de la vitre ou du pare-brise, par ('action du vent relatif tors du deplacement du vehicule, permettant de ce fait une meilleure adherence 25 de la raclette ou lame d'essuyage sur la vitre ou le pare-brise.  It is provided on the outer surface of the upper wall 5 of the central body 4 an upper rib 9 directed vertically upwardly. Complementarily, the upper rib 9 is shaped so as to produce bearing forces of the wiper blade 1 on the surface of the window or windshield by the action of the relative wind while the vehicle is moving. thus allowing a better grip of the squeegee or wiper blade on the window or windshield.

II est egalement prevu sur la paroi inferieure 6 du corps central 4 des moyens d'accrochage d'une raclette ou lame d'essuyage 13 (non representee sur la figure 1 mais sur les figures 2 a 4) sous la forme d'une paire de crochets longitudinaux opposes 6a diriges I'un vers I'autre et formant un espace interieur 10.  It is also provided on the lower wall 6 of the central body 4 of attachment means of a squeegee or wiper blade 13 (not shown in Figure 1 but in Figures 2 to 4) in the form of a pair opposed longitudinal hooks 6a directed towards each other and forming an interior space 10.

La nervure superieure 9 presente un decrochement 11 dans lequel les moyens de liaison ou connecteur 8, formes de deux pieces identiques 12, sont montes sur la monture support 2.  The upper rib 9 has a step 11 in which the connecting means or connector 8, forms of two identical pieces 12, are mounted on the support frame 2.

La figure 2 est une vue en perspective d'un dispositif de fart anterieur montrant I'etape de solidarisation, et avant verrouillage, de d'une lame d'essuie-glace 13 a la monture support 2 d'un balai d'essuie-glace.  FIG. 2 is a perspective view of a prior art device showing the securing step, and before locking, of a windscreen wiper blade 13 to the support frame 2 of a wiper blade; ice cream.

La lame d'essuyage 13 est de type connue en soi et se compose avantageusement de : - une tete ou partie dite superieure 14 sous la forme d'un element longitudinal presentant une coupe transversale sensiblement rectangulaire avec les quatre coins arrondis ; - une partie dite inferieure 15 sous la forme d'un element longitudinal presentant vu en coupe transversale une forme triangulaire, avantageusement isocele dont la pointe 15a est directement en contact avec la vitre ou le pare-brise devant etre essuye(e), et - une partie intermediaire 16 sous la forme d'un element longitudinal presentant une coupe transversale en arc de cercle dont les deux extremites sont dirigees vers la partie inferieure 15.  The wiper blade 13 is of a type known per se and advantageously consists of: a head or upper part 14 in the form of a longitudinal element having a substantially rectangular cross-section with the four rounded corners; a so-called lower part 15 in the form of a longitudinal element having in cross section a triangular shape, advantageously isocele, the tip 15a is directly in contact with the glass or the windshield to be wiped, and - an intermediate portion 16 in the form of a longitudinal member having a cross-section in a circular arc whose two ends are directed towards the lower part 15.

La partie superieure 14 est avantageusement apte a etre inseree dans ('espace interieur 10 de la monture support 2.  The upper part 14 is advantageously able to be inserted into the inner space 10 of the support frame 2.

Les parties superieure 14 et intermediaire 16 sont reliees entre elles par un element de liaison dit superieur 17, sensiblement longitudinal, et les parties intermediaire 16 et inferieure 15 sont reliees egalement entre elles par un element de liaison dit inferieur 18, sensiblement longitudinal.  The upper 14 and intermediate 16 parts are interconnected by a so-called upper link member 17, substantially longitudinal, and the intermediate 16 and lower 15 parts are also interconnected by a connecting element said inferior 18, substantially longitudinal.

De maniere usuelle, les moyens de liaison 19 sont usuellement appeles end-clip par I'homme de fart et sont constitues d'un evidement interne 20 dans lequel est apte a titre inseree la vertebre 3 et d'un espace libre 21 dans lequel la partie superieure 14 de la lame 13 est apte a titre inseree.  In the usual manner, the connecting means 19 are usually called end-clip by the skilled person and consist of an internal recess 20 in which the vertebra 3 and a free space 21 in which the upper part 14 of the blade 13 is suitable for insertion.

Les moyens de liaison 19 presentent egalement des moyens de desolidarisation 22 de la vertebre 3 sous la forme d'un bouton poussoir 23 apte a exercer une pression sur une languette interne 24 (representee sur la figure 4), flexible, integree dans les moyens de liaison 19, la languette flexible 24 presentant une extremite libre 25 avec un crochet 26 apte a maintenir la vertebre 3 quand celle-ci est inset-6e dans I'evidement interne 20.  The connecting means 19 also have means 22 for detaching the vertebra 3 in the form of a push button 23 able to exert pressure on an internal tongue 24 (represented in FIG. 4), which is flexible and integrated into the means of rotation. link 19, the flexible tongue 24 having a free end 25 with a hook 26 adapted to maintain the vertebra 3 when it is inset-6e in the inner recess 20.

De maniere plus precise, le bouton poussoir 23 est constitue d'une paroi 27 delimitee par une rainure 27a et ne presentant qu'un seul point de liaison 28 avec les moyens de liaison 19. Ainsi, quand I'utilisateur appuie sur le bouton poussoir 23, ('unique point de liaison 28 forme un axe de pivotement et la paroi 27 constitutive du bouton 23 pivote legerement vers I'interieur des moyens de liaison 19.  More specifically, the push button 23 is constituted by a wall 27 delimited by a groove 27a and having only one connection point 28 with the connecting means 19. Thus, when the user presses the push button 23, the single connecting point 28 forms a pivot axis and the wall 27 constituting the button 23 pivots slightly towards the inside of the connecting means 19.

25 De cette maniere, la paroi 27 vient avantageusement en butee contre ('extremite libre 25 de la languette flexible 24 et entraine ainsi son elevation partielle.  In this way, the wall 27 advantageously abuts against the free end of the flexible tongue 24 and thus causes its partial elevation.

De cette fawn, le crochet 26 ne maintient plus la vertebre 3 et celle-ci 30 peut titre desolidarisee des moyens de liaison 19.20 Les moyens de liaison 19 sont avantageusement conformes de maniere a etre de forme complementaire a la monture support 2 qui est apte a s'engager dans les moyens de liaison 19. Les moyens de liaison 19 presentent une paire de crochets 29 apte a s'engager et a entourer la partie superieure 14 de la lame d'essuie-glace 13.  In this way, the hook 26 no longer holds the vertebra 3 and the latter 30 may be unconnected from the connecting means 19.20 The connecting means 19 are advantageously conformed so as to be of complementary shape to the support frame 2 which is suitable for engage in the connecting means 19. The connecting means 19 have a pair of hooks 29 adapted to engage and surround the upper portion 14 of the windscreen wiper blade 13.

10 II est egalement prevu sur les moyens de liaison 19 une paire de languettes 30 presentant un orifice central 31, les languettes 30 etant disposees de part et d'autre des crochets 29 et entourent ainsi lateralement la partie superieure 14 de la lame d'essuie-glace 13, quand celle-ci est inseree dans I'espace libre 21 des moyens de liaison 19 et 15 dans I'espace interieur 10 de la monture support 2.  It is also provided on the connecting means 19 a pair of tongues 30 having a central orifice 31, the tongues 30 being arranged on either side of the hooks 29 and thus laterally surround the upper portion 14 of the wiper blade -glace 13, when it is inserted in the free space 21 of the connecting means 19 and 15 in the interior space 10 of the support frame 2.

Un dispositif de liaison sous la forme d'une lamelle 33 est apte a s'inserer dans les orifices 31 des languettes 30 ainsi que dans un orifice 34 prevu dans ('element de liaison superieur 17 de la lame 13. 20 Les moyens de liaison 19 sont ainsi conformes de maniere a ce que les orifices 31 des pattes 30 soient en face de ('orifice 34 de la partie intermediaire superieure 17 pour permettre ('insertion de la lamelle 33 dans les trois orifices (31, 34), realisant ainsi la liaison de la lame 25 d'essuieglace 13 sur la monture support 2.  A connecting device in the form of a lamella 33 is able to fit into the orifices 31 of the tongues 30 as well as into an orifice 34 provided in the upper connecting element 17 of the blade 13. The connecting means 19 are thus conformed so that the orifices 31 of the tabs 30 are in front of the orifice 34 of the upper intermediate part 17 to allow (insertion of the lamella 33 into the three orifices (31, 34), thereby realizing the connection of the wiper blade 13 to the support frame 2.

La figure 3 est une vue en perspective de I'etape de solidarisation, et avant verrouillage, de la monture support 2 d'un balai d'essuie-glace a une lame d'essuie-glace 13 selon un mode de realisation de ('invention. 30 Selon ce mode de realisation, les moyens de liaison 19 comportent une paire de pattes 30 traversees par un orifice 31.  FIG. 3 is a perspective view of the securing step, and before locking, of the support frame 2 of a wiper blade to a windscreen wiper blade 13 according to an embodiment of According to this embodiment, the connecting means 19 comprise a pair of lugs 30 traversed by an orifice 31.

A la difference du mode de realisation tel que decrit dans la figure 2, le dispositif de liaison 19 est constitue par une clavette 32 de verrouillage, de forme generale cylindrique. La clavette 32 comporte une tige centrale 35 et des parties d'extremite 36 et 37 en excroissance, plus particulierement de forme cylindrique, de plus grand diametre que le diametre de la tige 35.  Unlike the embodiment as described in Figure 2, the connecting device 19 is constituted by a locking key 32 of generally cylindrical shape. The key 32 comprises a central rod 35 and end portions 36 and 37 protruding, more particularly of cylindrical shape, of greater diameter than the diameter of the rod 35.

Un orifice 34 est prevu dans la partie intermediaire superieure 17 de la lame d'essuie-glace 13 dans lequel est apte a s'inserer la clavette 32, et plus precisement la tige 35.  An orifice 34 is provided in the upper intermediate portion 17 of the windscreen wiper blade 13 in which the key 32 can be inserted, and more precisely the rod 35.

De maniere alternative, ('orifice 34 est forme directement par insertion de Ia clavette 32 dans la partie intermediaire superieure 17 de la lame 13. Cette operation est facilement effectuee du fait: - du faible diametre des parties d'extremite 36 et 37; - de la faible difference de diametres entre ces derniers et la tige 35; et - que la clavette 32 est en metal et la lame 1 en elastomere.  Alternatively, the orifice 34 is formed directly by inserting the key 32 into the upper intermediate portion 17 of the blade 13. This operation is easily performed because of: the small diameter of the end portions 36 and 37; the small diameter difference between the latter and the rod 35, and - the key 32 is metal and the blade 1 elastomer.

Par ailleurs, du fait du faible diametre de la tige 35, sa presence n'a aucune incidence sur la souplesse de la partie inferieure 15 de la lame 13.  Moreover, because of the small diameter of the rod 35, its presence has no effect on the flexibility of the lower part 15 of the blade 13.

Les parties d'extremite 36 et 37 sont avantageusement de diametre tel qu'elles peuvent titre logees dans les orifices 31 des pattes 30, une fois que la clavette 32 traverse la partie intermediaire superieure 17, le diametre des parties d'extremite 36 et 37 etant sensiblement egal au diametre des orifices 31 des pattes laterales 30.30 II est possible d'adapter la taille des parties d'extremite en excroissance 36 et 37, et plus precisement leur diametre, en fonction de la distance entre les pattes 31 et I'espace libre 21 dans lequel est engagee la partie superieure 14 de la lame 13.  The end portions 36 and 37 are advantageously of diameter such that they may be housed in the orifices 31 of the lugs 30, once the key 32 passes through the upper intermediate portion 17, the diameter of the end portions 36 and 37 being substantially equal to the diameter of the orifices 31 of the lateral tabs 30.30 It is possible to adapt the size of the protruding end portions 36 and 37, and more precisely their diameter, as a function of the distance between the tabs 31 and the space 21 in which is engaged the upper portion 14 of the blade 13.

Sur la figure 4, on note qu'une des parties d'extremite 36 presente une longueur (dans le sens longitudinal de la clavette 32) plus grande que I'autre 37. Cette difference de longueur permet de tenir compte du fait que Ia distance entre I'espace libre 21 et les pattes 30 est plus grande pour la patte 31 situee sur le cote des moyens de liaison 19 presentant le bouton poussoir 23 par rapport a I'autre cote des moyens de liaison 19.  In Figure 4, it is noted that one of the end portions 36 has a length (in the longitudinal direction of the key 32) larger than the other 37. This difference in length allows to take into account that the distance between the free space 21 and the tabs 30 is greater for the tab 31 located on the side of the connecting means 19 having the push button 23 relative to the other side of the connecting means 19.

La longueur de la tige centrale 35 correspond sensiblement a la largeur (transversalement) de la partie superieure 14 de la lame 13. Le dispositif de I'invention assure une liaison fiable car la clavette ne peut pas se degager de maniere fortuite.  The length of the central rod 35 corresponds substantially to the width (transversely) of the upper portion 14 of the blade 13. The device of the invention provides a reliable connection because the key can not escape accidentally.

De maniere supplementaire ou alternative, it est prevu des crantages sur 20 au moins une partie de la surface des parties d'extremite en excroissance 36 et 37, aptes a cooperer avec des crantages prevus sur la surface interieure des orifices 31 des pattes 30, permettant ainsi un meilleur maintien de la clavette 32 dans les orifices 31.  In an additional or alternative manner, it is provided with notches on at least a portion of the surface of the protruding end portions 36 and 37, able to cooperate with notches provided on the inner surface of the orifices 31 of the tabs 30, allowing and better hold of the key 32 in the orifices 31.

25 Le mode de realisation de I'invention decrit ci-dessus prevoit que la tige 35 est pourvue a chacune de ses extremites d'une partie d'extremite 36, 37 en excroissance par rapport a Ia tige 35. Neanmoins, le dispositif decrit peut egalement fonctionner lorsque seule rune des deux parties d'extremite 36, 37 est pourvue d'un excroissance.The embodiment of the invention described above provides that the rod 35 is provided at each of its extremities with an end portion 36, 37 protruding from the rod 35. However, the device described may also operate when only rune of the two end portions 36, 37 is provided with an outgrowth.

30 Ceci est, par exemple, le cas Iorsque la tige 35 est de Iongueur inferieure a Ia distance entre les deux pattes 30. Ainsi, la premiere extremite permettant, par exemple, le percage de la lame d'essuie-glace 13, n'a pas necessite de passer au travers de la seconde patte 30 et de deboucher a I'exterieur de cette seconde patte 30. L'autre extremite est, quanta elle, pourvue dune partie en excroissance permettant le maintien de la lame d'essuie-glace 13 dans la monture support 2 et participe au fait d'eviter que la tige 35 ne puisse s'extraire de son logement.This is, for example, the case when the rod 35 is of length less than the distance between the two tabs 30. Thus, the first end allowing, for example, the drilling of the windscreen wiper blade 13, There is no need to pass through the second leg 30 and to emerge outside this second leg 30. The other end is, quanta, provided with a protruding portion for maintaining the wiper blade 13 in the support frame 2 and participates in preventing the rod 35 can be removed from its housing.
