Claims (3)

REVENDICATIONS 1. Articulation démontable d'une pièce articulée sur un support, caractérisée par le fait que ledit support (1) comprend deux saillies latérales (3) coopérant chacune avec deux pointes (11) de rétrécissement d'une rainure de guidage (9) formée dans la pièce articulée (2) et débouchant à la périphérie de celle-ci, le support (1) comprenant en outre un doigt élastique d'encliquetage (7) pénétrant dans une encoche (12) de la pièce articulée (2) lorsque lesdites saillies (3) sont chacune engagées entre les pointes (11) du rétrécissement de leur rainure (9) respective après avoir coulissé dans lesdites rainures (9).1. Removable articulation of a piece articulated on a support, characterized in that said support (1) comprises two lateral projections (3) each cooperating with two points (11) for narrowing a guide groove (9) formed in the articulated part (2) and emerging at the periphery thereof, the support (1) further comprising an elastic latching finger (7) penetrating into a notch (12) of the articulated part (2) when said projections (3) are each engaged between the points (11) of the narrowing of their respective groove (9) after having slid in said grooves (9). 2. Articulation selon la revendication 1, caractérisée en ce que le support (1) a, dans la zone d'articulation, une section en forme de U, lesdites saillies (3) étant portées par les ailes (4) du U en étant dirigées vers l'intérieur, lesdites rainures (9) étant formées sur les faces latérales de la pièce articulée (2).2. Articulation according to claim 1, characterized in that the support (1) has, in the articulation zone, a U-shaped section, said projections (3) being carried by the wings (4) of the U being directed inwards, said grooves (9) being formed on the side faces of the hinged part (2). La présente invention se rapporte à une articulation démontable en particulier pour balai d'essuie-glace pour véhicules automobiles.The present invention relates to a removable joint in particular for windscreen wiper blades for motor vehicles. Les balais d'essuie-glace sont constitués d'un support déformable portant une lame d'essuyage. En général, le support déformable est constitué d'un grand pont, destiné à être monté pivotant à l'extrémité d'un bras d'essuie-glace, et portant au moins à une de ses extrémités un petit pont monté pivotant. Chaque petit pont peut également servir de support à articulation à d'autres petits ponts.Wiper blades consist of a deformable support carrying a wiper blade. In general, the deformable support consists of a large bridge, intended to be pivotally mounted at the end of a windscreen wiper arm, and carrying at least at one of its ends a small pivotally mounted bridge. Each small bridge can also serve as a hinged support for other small bridges. Le nombre des articulations ainsi que les contraintes que subissent les balais rendent très délicate la fabrication des balais; en particulier, les articulations sont très importantes du point de vue fiabilité du produit, silence de fonctionnement et facilité de montage.The number of joints as well as the stresses undergone by the brushes make it very difficult to manufacture the brushes; in particular, the joints are very important from the point of view of product reliability, silent operation and ease of assembly. On a proposé de réaliser les articulations au moyen de rivets et, pour pallier les problèmes du jeu et de bruit, d'interposer une pièce intermédiaire un matière synthétique. Cependant, la construction d'une articulation par rivet est onéreuse et présente l'inconvénient de nécessiter une destruction en cas de mauvais fonctionnement.It has been proposed to make the joints by means of rivets and, to overcome the problems of play and noise, to interpose an intermediate piece of synthetic material. However, the construction of a joint by rivet is expensive and has the disadvantage of requiring destruction in the event of malfunction. On a également proposé d'utiliser des articulations clipsées qui sont d'un montage plus économique et peuvent être démontées. Cependant, leur construction et leur assemblage restent encore trop onéreux.It has also been proposed to use clipped joints which are more economical to assemble and can be dismantled. However, their construction and assembly are still too expensive. L'invention vise à obtenir un mode d'assemblage extrêmement simple et fiable, avec ces moyens très économiques.The invention aims to obtain an extremely simple and reliable method of assembly, with these very economical means. Ce but est atteint, conformément à l'invention, grâce à une articulation démontable d'une pièce articulée sur un support, caractérisée par le fait que ledit support comprend deux saillies latérales coopérant chacune avec deux pointes de rétrécissement d'une rainure de guidage formée dans la pièce articulée et débouchant à la périphérie de celle-ci, le support comprenant en outre un doigt élastique d'encliquetage pénétrant dans une encoche de la pièce articulée lorsque lesdites aillies sont chacune engagées entre les pointes du rétrécissement de leur rainure respective après avoir coulissé dans lesdites rainures.This object is achieved, in accordance with the invention, thanks to a dismountable articulation of a piece articulated on a support, characterized in that the said support comprises two lateral projections each cooperating with two points of narrowing of a guide groove formed in the articulated part and emerging at the periphery of the latter, the support further comprising an elastic latching finger penetrating into a notch of the articulated part when the said wings are each engaged between the points of the narrowing of their respective groove after having slid into said grooves. On obtient ainsi une articulation très efficace dans laquelle les pointes de rétrécissement servent d'axe de pivotement à chacune des saillies, dont l'introduction par la rainure ouverte est extrêmement simple. L'encliquetage du doigt dans l'encoche de la pièce articulée se produit automatiquement dès que cette pièce articulée arrive à sa position de fonctionnement. Le démontage se fait par les opérations inverses, après soulèvement du doigt d'encliquetage. On a représenté aux dessins annexées, à titre d'exemple non limitatif, une telle articulation. Dans ces dessins:A very effective articulation is thus obtained in which the narrowing points serve as a pivot axis for each of the projections, the introduction of which through the open groove is extremely simple. The snapping of the finger in the notch of the articulated part occurs automatically as soon as this articulated part arrives at its operating position. Dismantling is done by the reverse operations, after lifting the latching finger. There is shown in the accompanying drawings, by way of non-limiting example, such a joint. In these drawings: - la figure 1 est une vue schématique en élévation, partiellement en coupe, d'une articulation lors d'une phase préalable du montage;- Figure 1 is a schematic elevational view, partially in section, of an articulation during a preliminary phase of assembly; - la figure 2 est identique à la figure 1, pour la phase initiale du montage;- Figure 2 is identical to Figure 1, for the initial phase of assembly; - la figure 3 est identique aux figures 1 et 2, pour une phase intermédiaire du montage;- Figure 3 is identical to Figures 1 and 2, for an intermediate phase of assembly; - la figure 4 est identique aux figures 1 à 3, à la fin du montage;- Figure 4 is identical to Figures 1 to 3, at the end of the assembly; - la figure 5 est une vue en coupe de long de la ligne A-A de la figure.- Figure 5 is a sectional view along the line A-A of the figure. L'articulation comprend un support 1 sur lequel est articulée une pièce 2. Dans l'exemple décrit, le support 1 a une section en forme de U renversé et comporte deux saillies latérales 3 formées face à face dans les ailes 4 du U et tournées vers l'intérieur. Ces saillies 3 ont une forme allongée et peuvent être obtenues par moulage, par emboutissage, par découpage, etc., en fonction du matériau constituant le support 1. Le support 1 comporte en outre, dans sa face 5 joignant les deux ailes 4, une découpure 6 ménageant un doigt élastique 7 dont la face inférieure comporte un téton 8.The articulation comprises a support 1 on which a part 2 is articulated. In the example described, the support 1 has an inverted U-shaped section and comprises two lateral projections 3 formed face to face in the wings 4 of the U and turned towards the inside. These projections 3 have an elongated shape and can be obtained by molding, by stamping, by cutting, etc., depending on the material constituting the support 1. The support 1 further comprises, in its face 5 joining the two wings 4, a cutout 6 providing an elastic finger 7 whose underside has a stud 8. La pièce présente deux rainures latérales 9 débouchant à la périphérie de la pièce et comportant chacune un rétrécissement 10 formé par deux pointes 11 dont Pécartement est sensiblement égal à l'épaisseur des saillies The piece has two lateral grooves 9 emerging at the periphery of the piece and each comprising a constriction 10 formed by two points 11 whose spacing is substantially equal to the thickness of the projections 3. La face supérieure de la pièce 2 comporte en outre une encoche 12 qui se trouve en regard du téton 8 lorsque la zone centrale des saillies 3 est entre les pointes 11.3. The upper face of the part 2 further comprises a notch 12 which is opposite the stud 8 when the central zone of the projections 3 is between the points 11. Le montage se fait comme suit:The assembly is done as follows: On présente les saillies 3 à l'entrée des rainures 9 (figures 1 et 2) et on les fait coulisser le long des rainures 9 parallèlement à elles-mêmes. Le doigt élastique 7 se soulève (figure 3), le téton 8 glissant sur la face supérieure de la pièce 2. Lorsque les saillies 3 viennent en place entre les pointes 11 (figures 4 et 5), le téton 8 tombe dans l'encoche 12 sous l'action élastique du doigt 7 et l'articulation est ainsi verrouillé. L'articulation de la pièce 2 sur le support 1 se fait par pivotement des saillies 3 entre les pointes 11. Le démontage se fait en sens inverse après avoir soulevé le doigt 7.The projections 3 are presented at the entrance to the grooves 9 (FIGS. 1 and 2) and they are made to slide along the grooves 9 parallel to themselves. The elastic finger 7 rises (FIG. 3), the stud 8 sliding on the upper face of the part 2. When the projections 3 come into place between the points 11 (FIGS. 4 and 5), the stud 8 falls into the notch 12 under the elastic action of the finger 7 and the joint is thus locked. The articulation of the part 2 on the support 1 is done by pivoting the projections 3 between the points 11. Dismantling is done in the opposite direction after having lifted the finger 7. 22 ss 1010 1515 2020 2525 3030 3535 4040 4545 5050 5555 BB 1 feuille dessins1 drawing sheet
