The invention will be better understood, and other purposes, features, details and advantages thereof will appear more clearly in the following explanatory description made with reference to the accompanying schematic drawings given solely by way of example illustrating an embodiment of the invention and in which:
  • the figure 1 is a perspective view of a device for fixing a part on a support, according to the invention;
  • the figure 2 is a perspective view of the nut device 1 of the figure 1 in its open position;
  • the figure 3 is a perspective view of the nut device of the figure 2 in its closed position;

  • the FIGS. 5A to 5E illustrate various specific steps of the establishment first of the nut device according to the invention on the edge of the support and then the attachment of a part to this support.

La figure 1 illustre que le dispositif de fixation selon l'invention, désigné par la référence générale 1, permet de fixer une pièce 2 à un support 3, par exemple un mécanisme de levage et de descente d'une vitre d'une porte d'un véhicule automobile, à l'aide d'une vis de fixation 4.The figure 1 illustrates that the fixing device according to the invention, designated by the general reference 1, makes it possible to fix a part 2 to a support 3, for example a mechanism for lifting and lowering a window of a door of a vehicle automobile, using a fixing screw 4.

Comme le montre la figure 2, le dispositif écrou selon l'invention 1 présente une structure générale de portefeuille et comporte essentiellement une partie de base 6 susceptible d'être montée sur le bord 7 du support 3 et une partie en forme de volet 8 reliée à la partie de base par une charnière de pliage 10 permettant à ce volet de pivoter autour de cette charnière entre une position ouverte de l'écrou, selon la figure 2, et une position fermée selon la figure 3.As shown in figure 2 , the nut device according to the invention 1 has a general wallet structure and essentially comprises a base portion 6 that can be mounted on the edge 7 of the support 3 and a flap-shaped portion 8 connected to the base portion by a folding hinge 10 allowing this flap to pivot about this hinge between an open position of the nut, according to the figure 2 , and a closed position according to the figure 3 .

La partie de base 6 comporte une plaque de fond 12 repliée à une extrémité pour la formation d'un rebord perpendiculaire 13 au bord libre duquel est relié le volet 8, par l'intermédiaire de la charnière 10. Le rebord 13 porte à chaque extrémité de la charnière 10 un bras de renfort 14 qui s'étend parallèlement à la plaque de fond 12 et parallèlement aux bords latéraux 16 de celle-ci de façon à former avec ces bornes des parties en U permettant l'engagement de la partie de base sur le bord 7 du support 3, comme on le voit notamment sur les figures 5A et 5B. La plaque de fond 12 de la pièce de base 6 est pourvue d'une fenêtre 17 d'appui de la vis 2 lors du vissage. Le bord avant de la plaque 12 porte un rebord 18 en forme d'un L permettant la réception de la pièce 2, comme l'illustre la figure 1.The base portion 6 comprises a bottom plate 12 folded at one end for the formation of a flange perpendicular to the free edge 13 to which the flap 8 is connected, via the hinge 10. The flange 13 carries at each end of the hinge 10 a reinforcing arm 14 which extends parallel to the bottom plate 12 and parallel to the side edges 16 thereof so as to form with these terminals U-shaped parts allowing the engagement of the base part on the edge 7 of the support 3, as seen in particular on the Figures 5A and 5B . The bottom plate 12 of the base part 6 is provided with a window 17 for supporting the screw 2 during screwing. The front edge of the plate 12 carries a rim 18 in the shape of an L allowing the reception of the part 2, as illustrated by FIG. figure 1 .

Le volet pivotant 8 comprend essentiellement une plaque 19 portant au niveau de chacun de ses bords longitudinaux 20 une patte 21 de verrouillage du volet sur le bras 14 approprié de la partie de base 6 dans la position fermée de l'écrou, conformément à la figure 2, ainsi qu'au niveau de son bord libre un rebord 22 de recouvrement, dans la position fermée de l'écrou, de l'extrémité libre du bras de renfort approprié. Le volet 8 porte surtout sur sa face interne orientée vers la partie de base une saillie cylindrique en forme d'un fût 24 qui traverse la plaque 18 en 24' et dans lequel est pratiqué un trou fileté 25 de réception de la vis 2 lors de la fixation de la pièce 4 au support 3. Mais la face interne du fût pourrait être lisse et ce serait alors la vis qui réaliserait le taraudage. Une rondelle en caoutchouc 26 entoure le fût pour absorber des différences d'épaisseur du support 3. La face avant 28 du fût porte des saillies 29 destinées à s'engager dans des excroissances radiales 30 du trou 17 dans la plaque de base 12.The pivoting flap 8 essentially comprises a plate 19 carrying at each of its longitudinal edges 20 a lug 21 for locking the flap on the appropriate arm 14 of the base portion 6 in the closed position of the nut, in accordance with the figure 2 as well as at its free edge a flange 22 covering, in the closed position of the nut, the free end of the appropriate reinforcement arm. The flap 8 focuses on its inner face oriented towards the base portion a cylindrical projection in the form of a barrel 24 which passes through the plate 18 at 24 'and in which is formed a threaded hole 25 for receiving the screw 2 when fixing the part 4 to the support 3. But the inner face of the barrel could be smooth and it would be then the screw that would perform the tapping. A rubber washer 26 surrounds the barrel to absorb differences in thickness of the support 3. The front face 28 of the barrel carries projections 29 for engaging in radial protuberances 30 of the hole 17 in the base plate 12.

Concernant les deux pattes de verrouillage 21, elles ont chacune la configuration d'un L dont une branche est solidaire du volet 20 et s'étend sensiblement parallèlement au plan de celui-ci, tandis que l'autre extrémité est configurée en élément de crochet 23 susceptible de venir en prise sous le bras de renfort 14 correspondant de la partie de base 6, dans la position fermée de l'écrou montré à la figure 2. Les pattes sont élastiquement déformables pour pouvoir être enlevées des bras. L'écrou est donc susceptible d'être réouvert.Regarding the two locking tabs 21, they each have the configuration of an L of which one branch is integral with the flap 20 and extends substantially parallel to the plane thereof, while the other end is configured as a hook element 23 engageable under the reinforcement arm 14 corresponding to the base portion 6 , in the closed position of the nut shown in figure 2 . The tabs are elastically deformable to be removed from the arms. The nut is therefore likely to be reopened.

En se reportant aux figures 5, on constate que la fixation de la pièce 2 sur le support 3 commence par l'engagement de l'écrou 1, à l'état ouverte, sur le bord 7 du support 3, comme l'illustrent les figures 5A et 5B. Puis on ferme l'écrou par pivotement ou pliage du volet 8 sur la partie de base 6, de la manière indiquée par la flèche sur la figure 5C. Lors du pivotement, le fût de vissage 24 du volet 8 s'engage dans un trou de forme complémentaire 27 pratiqué dans le support 3. La figure 5D montre le dispositif écrou dans sa position montée sur le bord du support. Dans cette position, le fût est engagé dans son trou de réception 27 et les pattes de verrouillage 21, suite à l'application des forces de pression en direction des flèches, verrouillent le volet 8 sur la partie de base du fait que les extrémités en forme de crochet des pattes vient en prise sous les bras de renfort 14. On constate qu'à l'état fermé de l'écrou, les éléments 22 et les pattes 21 enveloppent les deux bras 14.Referring to figures 5 it is found that the fixing of the part 2 on the support 3 begins with the engagement of the nut 1, in the open state, on the edge 7 of the support 3, as illustrated by the Figures 5A and 5B . Then the nut is closed by pivoting or folding the flap 8 on the base portion 6, as indicated by the arrow on the Figure 5C . During pivoting, the screwing barrel 24 of the flap 8 engages a hole of complementary shape 27 formed in the support 3. figure 5D shows the nut device in its position mounted on the edge of the support. In this position, the barrel is engaged in its receiving hole 27 and the locking lugs 21, following the application of the pressure forces in the direction of the arrows, lock the flap 8 on the base part of the fact that the ends in hook form of the tabs engages under the reinforcing arms 14. It is noted that in the closed state of the nut, the elements 22 and the tabs 21 envelop the two arms 14.

Ensuite, conformément à la figure 5E, la pièce 2 est mise en place en faisant glisser son bord avant 28 dans l'extrémité 18 en U de la plaque de base 6. Dans cette position, la pièce 2 est fixée sur le support 3 à l'aide de la vis 3 de la manière illustrée à la figure 1 par les flèches.Then, according to the figure 5E the piece 2 is put in place by sliding its front edge 28 into the U-shaped end 18 of the base plate 6. In this position, the piece 2 is fixed on the support 3 with the aid of the screw 3 as illustrated in the figure 1 by the arrows.

I1 est à noter que lors du vissage de la vis, l'opérateur n'appuie pas sur la partie verrouillée de l'écrou, c'est-à-dire le volet 8 maintenu en place grâce aux pattes 21 de verrouillage élastiquement déformables et donc amovibles, en raison de la forme plus petite de la fenêtre 17 dans la plaque de base 12. Lors du vissage, le volet est retenu grâce aux deux bras de renfort 14. Du fait que les bras sont enveloppés par les pattes 21 ainsi que les éléments 22, l'effort de vissage est bien réparti sur les deux bras.It should be noted that during the screwing of the screw, the operator does not rest on the locked part of the nut, that is to say the flap 8 held in place thanks to the elastically deformable locking tabs 21 and therefore removable, because of the smaller shape of the window 17 in the base plate 12. During screwing, the flap is retained by the two reinforcing arms 14. Because the arms are wrapped by the legs 21 and that the elements 22, the screwing force is well distributed on both arms.

Il ressort de la description qui précède, que l'invention présente de nombreux avantages majeurs par rapport à l'état de la technique. Ainsi les pattes 21 et les éléments 22 qui enveloppent les deux bras de renfort 14 permettent de passer un couple de serrage très important. Le montage en portefeuille assure une bonne tenue de l'écrou d'agrafe en forme de portefeuille sur le support. Lors du vissage la vis pousse sur la face de la plaque de base du dispositif écrou, ce qui évite tout décollement du volet qui comporte le fût fileté ou lisse. La rondelle en caoutchouc 26 permet d'absorber des différences d'épaisseur du support. Grâce à tous les avantages et particularités de l'invention, le dispositif écrou susceptible d'être pré-assemblé sur le support 1 permet la fixation sur ce support des pièces par vissage de vis à matériau tendre.It follows from the foregoing description that the invention has many major advantages over the state of the art. Thus the tabs 21 and the elements 22 which envelop the two reinforcing arms 14 allow to pass a very large tightening torque. The wall mounting ensures a good holding of the clip-shaped nut on the support. During screwing the screw pushes on the face of the base plate of the nut device, which avoids any detachment of the flap which comprises the threaded or smooth shaft. The rubber washer 26 can absorb differences in the thickness of the support. Thanks to all the advantages and peculiarities of the invention, the nut device capable of being pre-assembled on the support 1 allows fixing on the support of the parts by screwing screws with soft material.
