Abstract

The hinge of a component (2) on a support (1) is obtained by virtue of two projections (3) integral with the support and each engaged between the narrowing points (11) of a groove (9) formed in the hinged component (2). A stub (8) is pressed by an elastic finger (7) of the support (1) into a click-in notch (12) of the hinged component (2). When the elastic finger (7) is slightly raised, the articulated component (2) may be dismantled, the projections (3) sliding in the grooves (9).

Description

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 articulation in particular for 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 egalement servir de support à articulation à d'autres petits ponts. The 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 wiper arm, and carrying at least at one of its ends a small pivotally mounted bridge. Each small bridge can also serve as a hinge 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 on the brushes make the manufacture of brushes very delicate; 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 de jeu et de bruit, d'interposer une piece intermédiaire en 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 produce 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 rivet joint is expensive and has the disadvantage of requiring destruction in the event of malfunction.

On a également proposé d'utiliser des articulatiorts clipsées qui sont d'un montage plus économique et peuvent être démontées. It has also been proposed to use clipped articulations which are of a more economical assembly and can be dismantled.

Cependant, leur construction et leur assemblage restent encore trop onéreux.However, their construction and assembly are still too expensive.

L'invention vise à obtenir un mode d'assemblage extrèmement simple et fiable, avec des moyens très économiques. The invention aims to obtain an extremely simple and reliable method of assembly, with 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 piece 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 saillies 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 removable articulation of a part articulated on a support, characterized in that said support comprises two lateral projections each cooperating with two shrinking points of a formed guide groove in the articulated piece and emerging at the periphery thereof, the support further comprising an elastic snap-in finger penetrating into a notch of the articulated piece when said projections are each engaged between the points of the narrowing of their respective grooves after having slid in 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 extrèmement 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
- la figure 1 est une vue schématique en élévation, partiellement en coupe, d'une articulation lors d'une phase préalable du montage;
- la figure 2 est identique à la figure 1, pour la phase initiale du montage;
- la figure 3 est identique aux figures 1 et 2, pour une phase intermédiaire du montage;
- la figure 4 est identique aux figures 1 à 3, à la fin du montage;
- la figure 5 est une vue en coupe le long de la ligne A-A de la figure 4.
A very effective joint is thus obtained in which the narrowing points serve as a pivot axis for each of the projections, the introduction of which by the open groove is extremely simple. The snap of the finger into the notch of the articulated part occurs automatically as soon as this articulated part reaches its operating position. Disassembly is done by reverse operations, after lifting of the locking finger. There is shown in the accompanying drawings, by way of nonlimiting example, such a joint. In these drawings
- Figure 1 is a schematic elevational view, partially in section, of a joint during a prior phase of assembly;
- Figure 2 is identical to Figure 1, for the initial phase of assembly;
- Figure 3 is identical to Figures 1 and 2, for an intermediate phase of assembly;
- Figure 4 is identical to Figures 1 to 3, at the end of the assembly;
- Figure 5 is a sectional view along line AA of Figure 4.

L'articulation comprend un support 1 sur lequel est articulée une pièce 2. Dans l'exemple décrit, le support I a une section en forme de U renverse 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 ei: peuvent etre 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 piece 2 is articulated. In the example described, the support I has a U-shaped cross section and has 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 ei: 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 cut-out 6 providing an elastic finger 7, the lower face of which comprises a stud 8.

La pièce 2 présente deux rainures latérales 9 débouchant à la périphérie de la pièce et comportant chacune un rétrécissement 10 forme par deux pointes il dont l'écartement est sensiblement égal à l'épaisseur des saillies 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.  The part 2 has two lateral grooves 9 opening at the periphery of the part and each comprising a narrowing 10 formed by two points il whose spacing is substantially equal to the thickness of the projections 3. The upper face of the part 2 comprises in addition to a notch 12 which is located opposite the stud 8 when the central zone of the projections 3 is between the points 11.

Le montage se fait comme suit:
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-memes. 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 11 articulation est ainsi verrouillée. L'articulation de la pièce 2 sur le support I 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 assembly is done as follows:
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 lifts (FIG. 3), the stud 8 sliding on the upper face of the part 2. When the projections 3 come into place between the tips 11 (FIGS. 4 and 5), the stud 8 falls into the notch. 12 under the elastic action of the finger 7 and 11 articulation is thus locked. The articulation of the part 2 on the support I is made by pivoting of the projections 3 between the points 11. The disassembly is done in the opposite direction after having raised the finger 7.
