Description
La présente invention concerne les dispositifs d'essuieglace, notavent pour véhicules automobiles et plus précisénent un tel dispositif comportant des moyens permettant de soulever les balais d'essuie-glace en position de repos. The present invention relates to wiper devices, notavent for motor vehicles and more precisely such a device comprising means for lifting the wiper blades in the rest position.
De tels moyens sont mis en oeuvre soit afin de libérer, en position de repos, la raclette de la pression de service et ainsi éviter des défornations, soit lorsqu'une position de retrait, dite de parking, est prévue dans le cycle d'essuyage. En effet, dans une telle position de retrait, le balai d'essuie-glace est amené en dessous du pare-brise du véhicule ce qui oblige de faire passer la raclette au dessus du joint entourant usuellement ledit pare-brise. Such means are implemented either in order to release, in the rest position, the squeegee from the operating pressure and thus avoid deformation, or when a withdrawal position, called parking, is provided in the wiping cycle . In fact, in such a withdrawal position, the wiper blade is brought below the vehicle windshield, which means that the squeegee must pass over the seal usually surrounding said windshield.
Il a déjh été proposé de soulever le balai en position de repos en faisant collaborer des butées fixées au bord du pare-brise avec un déflecteur d'air prévu sur ledit balai, mais ce type de dispositif est coûteux puisqu'il nécessite la mise en oeuvre d'un balai avec déflecteur. It has already been proposed to raise the broom in the rest position by making stops fixed at the edge of the windshield collaborate with an air deflector provided on said broom, but this type of device is expensive since it requires setting up work of a broom with deflector.
Lorsque le soulèvenent du balai d'essuie-glace doit se faire alors que celui-ci est en position de retrait, il est connu de positionner en dessous du pare-brise des moyens de rampe collaborant avec le porte-balai afin de le soulever. Ces moyens donnent satisfaction mais dans le cas des porte-balai6 peints, la peinture résiste mal au frottement ce qui fait apparaitre des rayures favorisant l'attaque de la rouille. When the lifting of the wiper blade must be done while it is in the retracted position, it is known to position below the windshield ramp means collaborating with the brush holder in order to lift it. These means are satisfactory, but in the case of painted brush holders, the paint has poor resistance to friction, which causes scratches to appear which favor the attack of rust.
Afin de pallier cet inconvénient, la présente invention propose un essuie-glace pour véhicules automobiles, du genre comportant un porte-balai coopérant avec des doyens de soulèvenent, caractérisé en ce que la face inférieure dudit porte-balai est au moins en partie recouverte, dans la zone destinée 8 coopérer avec lesdits moyens de soulevement, par un dispositif de protection. In order to overcome this drawback, the present invention provides a windscreen wiper for motor vehicles, of the type comprising a brush holder cooperating with lifting deans, characterized in that the underside of said brush holder is at least partially covered, in the intended area 8 cooperate with said lifting means, by a protection device.
Le dispositif de protection objet de la présente invention présente de plus les avantages d'être de fabrication simple et de montage aisé et rapide. The protection device object of the present invention also has the advantages of being simple to manufacture and easy and quick to assemble.
Ces avantages ressortiront de la description d'un exemple de réalisation préféré de l'invention qui va suivre en référence aux dessins dans lesquels
- la figure 1 est une vue de dessous d'un dispositif suivant l'invention,
- la figure 2 est une vue en coupe suivant la ligne Il-Il de la figure 1.These advantages will emerge from the description of a preferred embodiment of the invention which follows with reference to the drawings in which
FIG. 1 is a bottom view of a device according to the invention,
- Figure 2 is a sectional view along the line II-II of Figure 1.
- la figure 3 est une vue suivant la flèche F de la figure 1. - Figure 3 is a view along arrow F of Figure 1.
- la figure 4 est une vue en coupe suivant la ligne
IV-IV de la figure 3.- Figure 4 is a sectional view along the line
IV-IV of figure 3.
- la figure 5 est une vue en perspective d'un portebalai muni d'un essuie-glace suivant l'invention. - Figure 5 is a perspective view of a balance holder provided with a wiper according to the invention.
De manière usuelle, le porte-balai comporte deux parties : le carter 21 en métal plié et le bras 22 introduit dans ce carter, reliés par des moyens connus non représentés. Usually, the brush holder has two parts: the folded metal casing 21 and the arm 22 inserted into this casing, connected by known means, not shown.
Comme visible sur les figures et plus spécialement à la figure 5, le dispositif de protection permettant la mise en oeuvre de l'invention se présente sous la forme d'un manchon 1. ledit manchon a globalement la forme d'un parallèlépipède rectangle creux destiné à envelopper le porte-balai 2. As can be seen in the figures and more particularly in FIG. 5, the protection device allowing the implementation of the invention is in the form of a sleeve 1. said sleeve generally has the form of a hollow rectangular parallelepiped intended for wrap the brush holder 2.
De manière préférée, pour améliorer l'esthétique du porte-balai 2 muni du manchon de protection 1, ledit manchon sera prévu de manière à chevaucher la jonction du carter 21 et du bras 22 ; il cache ainsi l'épaulement 23 présent à cette jonction. Preferably, to improve the aesthetics of the brush holder 2 provided with the protective sleeve 1, said sleeve will be provided so as to overlap the junction of the casing 21 and the arm 22; it thus hides the shoulder 23 present at this junction.
Le parallélépipède est tsjl que l'ouverture arrière 11 soit de dimensions semblables a celles du carter 21 vers l'avant, la section du manchon se réduit régulièrement afin que l'ouverture avant 12 soit de dimensions semblables a celles du bras 22. The parallelepiped is that the rear opening 11 is of dimensions similar to those of the casing 21 towards the front, the section of the sleeve is reduced regularly so that the front opening 12 is of dimensions similar to those of the arm 22.
Bien entendu les ouvertures 11 et 12 seront de dimensions semblables, mais légèrement supérieures à celles du carter et du bras. Of course the openings 11 and 12 will be of similar dimensions, but slightly larger than those of the casing and the arm.
La surface interne du manchon comporte un épaulement 13 destiné & entre positionné contre l'épaulenent 23 du porte-balai 2. The internal surface of the sleeve has a shoulder 13 intended for between positioned against the shoulder 23 of the brush holder 2.
De manière connue en soi, le carter 21 est formé à partir d'un profilé en U présentant deux ailes 24 qui sont, au cours du montage, repliées vers l'intérieur du U afin de former un logement pour le bras 22 ; ces ailes sont généralenet espacées l'une de l'autre. In a manner known per se, the casing 21 is formed from a U-shaped profile having two wings 24 which are, during assembly, folded towards the inside of the U so as to form a housing for the arm 22; these wings are generally spaced from each other.
Afin d'assurer un guidage permettant une mise en place précise du manchon 1, la surface interne de celuici présente une nervure 15 destinée à pénétrer dans l'espace 25 séparant lesdites ailes 24 ; ladite nervure 15 est de dimensions semblables nais légèrement inférieures à celles dudit espace 25. In order to provide guidance allowing precise positioning of the sleeve 1, the internal surface of this has a rib 15 intended to penetrate into the space 25 separating said wings 24; said rib 15 is of similar dimensions but slightly smaller than those of said space 25.
Dans le prolongement de la nervure 15, le manchon présente une ouverture 16 longitudinale ; une languette élastique 17 dont une extrémité est liée & un bord de l'ouverture 16 s'étend à l'intérieur de cette ouverture 16. In the extension of the rib 15, the sleeve has a longitudinal opening 16; an elastic tongue 17, one end of which is linked to an edge of the opening 16 extends inside this opening 16.
La languette élastique 17 présente à son extrémité libre un ergot 18 dont la face située en vis h vis de la nervure 15 est de même section que ladite nervure. The elastic tongue 17 has at its free end a lug 18, the face located opposite h vis of the rib 15 is of the same section as said rib.
Cet ergot 18 est destiné à coopérer avec un pion 29 du porte-balai 2 ; ledit pion peut, tel que représenté, être forme par deux dents 27 des ailes 24 qui, lors du pliage de celles-ci définissent un épaulement 28 contre lequel l'ergot 18 vient en butée. This lug 18 is intended to cooperate with a pin 29 of the brush holder 2; said pin can, as shown, be formed by two teeth 27 of the wings 24 which, when folding these define a shoulder 28 against which the lug 18 abuts.
le positionnement du manchon 1 sur le porte-balai 2 est défini par la coopération de l'épaulenent 13 et de l'ergot 18 avec les épaulement 23 et 28 du bras afin d'arrêter tout mouvement longitudinal, et, par la coopération de la nervure 15 avec les bords des ailes délimitant l'espace 25, afin d'arrêter tout mouvement transversal. the positioning of the sleeve 1 on the brush holder 2 is defined by the cooperation of the shoulder 13 and the lug 18 with the shoulders 23 and 28 of the arm in order to stop any longitudinal movement, and, by the cooperation of the rib 15 with the edges of the wings delimiting the space 25, in order to stop any transverse movement.
On comprend que le manchon 1 recouvre une partie de la face inférieure 20 du porte-balai 2. Cette face inférieure 20 est la face du porte-balai 2 qui, lorsque celui-ci est monté sur un véhicule se trouve dirigée vers le pare-brise, c'est donc la face par laquelle ledit porte-balai sera amené à glisser sur les moyens de rampe fixés audit pare-brise pour le soulever. It is understood that the sleeve 1 covers part of the lower face 20 of the brush holder 2. This lower face 20 is the face of the brush holder 2 which, when the latter is mounted on a vehicle is directed towards the barrier. breeze, it is therefore the face by which said brush holder will be caused to slide on the ramp means fixed to said windshield to lift it.
Dans le mode préféré d'exécution qui est représenté aux figures, le manchon est tel qu'il recouvre la quasitotalité de la surface concernée du porte-balai ce qui crée un ensemble plus esthétique et permet, comme on va le décrire maintenant un montage aisé ; il est réalisé par moulage d'une matière plastique ce qui le rend peu coûteux. In the preferred embodiment which is shown in the figures, the sleeve is such that it covers almost the entire surface concerned of the brush holder, which creates a more aesthetic assembly and allows, as will now be described, easy mounting. ; it is made by molding a plastic material which makes it inexpensive.
Pour son montage, le manchon 1 est fendu longitudinalement sur un de ses petits côtés. For its assembly, the sleeve 1 is split longitudinally on one of its short sides.
La fente 19, visible sur les figures 2 et 3, laisse libre un passage de hauteur légèrement inférieure à l'épaisseur e du bras 22. The slot 19, visible in FIGS. 2 and 3, leaves free a passage of height slightly less than the thickness e of the arm 22.
Pour mettre en place le manchon 1 sur le porte-balai 2, on le positionne tout d'abord autour du bras 22 en introduisant ledit bras 22 dans la fente 19 au cours d'un mouvement transversal, c'est-à-dire d'un mouvement dans une direction perpendiculaire i la flèche F de la figure 1 ; ceci est possible grâce & l'élasticité de la matière utilisée pour la fabrication dudit manchon. Le manchon doit être positionné sur une partie du bras 22 extérieure au carter 21 avec l'ouverture 11 dirigée vers ledit carter 21, et la nervure 15 contre la face inférieure 20 du porte-balai. To set up the sleeve 1 on the brush holder 2, it is first positioned around the arm 22 by introducing said arm 22 into the slot 19 during a transverse movement, that is to say d 'a movement in a direction perpendicular to the arrow F in Figure 1; this is possible thanks to the elasticity of the material used for the manufacture of said sleeve. The sleeve must be positioned on a part of the arm 22 external to the casing 21 with the opening 11 directed towards said casing 21, and the rib 15 against the underside 20 of the brush holder.
Puis, dans un deuxième temps on fait coulisser longitudinalement ledit manchon dans le sens de la flèche
F afin qu'il chevauche le carter 21. Then, in a second step, said sleeve is made to slide longitudinally in the direction of the arrow.
F so that it overlaps the casing 21.
le mouvement se poursuit jusqu'à ce que l'épaulement 13 vienne en butée contre l'épaulement 23 et l'ergot 18 contre l'épaulement 28. the movement continues until the shoulder 13 abuts against the shoulder 23 and the lug 18 against the shoulder 28.
