This pre-assembly is designed so that the screw and the dowel cannot be uncoupled before it is inserted into the component to be positioned and fixed in a structural part.
Etat de la techniqueState of the art
Dans l'état de la technique, le brevet FR2976987 décrit un dispositif de montage pour la fixation rotative et imperdable d'un élément mécanique pourvu d'un perçage. Le dispositif comporte une vis filetée et une bague de montage annulaire comprenant au moins un organe de retenue élastique admettant une position de verrouillage dans laquelle l'élément mécanique engagé sur la bague est bloqué en translation selon l'axe de la bague tout en pouvant pivoter librement autour cette dernière la bague étant elle-même montée dans l’organe à fixer. Dans cette configuration la tête de la vis repose sur l’extrémité de la bague puis la vis est montée par vissage sur l’organe dans sa position définitive.In the state of the art, the patent FR2976987 describes a mounting device for the rotatable and captive fixing of a mechanical element provided with a bore. The device comprises a threaded screw and an annular assembly ring comprising at least one elastic retaining member admitting a locking position in which the mechanical element engaged on the ring is locked in translation along the axis of the ring while being able to pivot freely around the latter, the ring itself being mounted in the member to be fixed. In this configuration, the head of the screw rests on the end of the ring, then the screw is screwed onto the component in its final position.
Ce dispositif comprend une bague dans laquelle une vis est montée de façon rotative. La bague et la vis sont positionnés en vis-à-vis de l’organe à assembler et fixer à l’aide d’un outil approprié. On comprend que ce dispositif n’est pas évident à centrer sur l’organe à assembler, et qu’il faut ensuite la visser, ce qui est consommateur de temps de montage.This device comprises a ring in which a screw is rotatably mounted. The ring and the screw are positioned opposite the component to be assembled and fixed using an appropriate tool. It is understood that this device is not easy to center on the organ to be assembled, and that it must then be screwed, which consumes assembly time.
Le but de l'invention est donc de proposer un dispositif de fixation comportant une vis pré montée dans une cheville, simple à accoster, apte à bloquer instantanément un organe à assembler sur une structure, avec un faible coût et facile à mettre en œuvre.The object of the invention is therefore to provide a fixing device comprising a screw pre-mounted in a dowel, simple to dock, able to instantly block a member to be assembled on a structure, with low cost and easy to implement.
A cet effet, la présente invention a pour objet un dispositif de fixation comprenant une vis comportant une tête et un fût, pré montée dans une cheville comprenant un corps et un fourreau, la cheville comportant un alésage intégrant des moyens de verrouillage venant en prise dans des moyens de retenue ménagé sur le fût de la vis, afin que le fût de la vis soit en partie engagé dans la cheville dans une position déterminée.To this end, the subject of the present invention is a fastening device comprising a screw comprising a head and a shaft, pre-mounted in a dowel comprising a body and a sheath, the dowel comprising a bore integrating locking means engaging in retaining means provided on the shaft of the screw, so that the shaft of the screw is partly engaged in the dowel in a determined position.
Avantageusement, le fourreau de la cheville est fendu sur sa longueur pour former deux ailettes refermée à leurs extrémités, les moyens de verrouillage étant des ergots solidarisés à l’intérieur des ailettes.Advantageously, the sheath of the ankle is split along its length to form two fins closed at their ends, the locking means being lugs secured inside the fins.
Suivant une autre caractéristique avantageuse, les moyens de verrouillage sont munis de chanfreins.According to another advantageous characteristic, the locking means are provided with chamfers.
Suivant une autre caractéristique, le corps de la cheville comporte une section cylindrique muni de méplat se prolongeant par une portion cylindrique, une rainure de section carrée puis par une platine rectangulaire, munis de chanfrein, de longueur identique à ladite section cylindrique.According to another characteristic, the body of the pin comprises a cylindrical section provided with a flat extending by a cylindrical portion, a groove of square section then by a rectangular plate, provided with a chamfer, of identical length to said cylindrical section.
Selon une variante, la tête de la vis est en appui sur la face du corps de la cheville en position d’utilisation, l’extrémité du fourreau accoste dans les moyens de retenue, la vis est étant plus longue que la cheville.According to a variant, the head of the screw bears against the face of the body of the dowel in the position of use, the end of the sheath docks in the retaining means, the screw being longer than the dowel.
Selon une autre variante, l’alésage comporte un embrèvement interne à proximité de l’ouverture chanfreiné depuis la face du corps de la cheville.According to another variant, the bore has an internal recess near the chamfered opening from the face of the body of the pin.

Description détaillée de l'inventionDetailed description of the invention
La figure 1 est une vue schématique en perspective d’un dispositif de fixation 1 comportant une vis 2 pré montée dans une cheville 3, apte à fixer instantanément un organe sur un élément de structure d’un véhicule. La vue montre uniquement la partie supérieure de la vis 2, tandis que la partie inférieure est introduite dans la cheville 3 de façon imperdable. La partie supérieure de la vis 2 comporte une tête 4 prolongé par un secteur cylindrique lisse 5 menant sur une collerette 6 de largeur et hauteur limité, se prolongeant par un fût cylindrique striée 7 d’un diamètre identique à celui du secteur lisse 5. La partie inférieure de la vis 2 sera décrite plus loin. La cheville 3 comprend un corps 8 comprenant un tronçon cylindrique 9 comportant des méplats 9a diamétralement opposés sur une partie de sa longueur se prolongeant par une portion cylindrique de faible épaisseur 10, et une rainure de section carrée 12 et de longueur sensiblement égale à un côté du carré, puis ensuite se prolongeant par une platine rectangulaire 13 de côté égal sur sa longueur au diamètre de la section cylindrique 10, d’épaisseur inférieur au côté de la rainure de section carrée 12. Ledit rectangle 13 est obtenu par troncature des deux côtés opposés 17. Des chanfreins 14 sont façonnés sur les deux autres côtés du rectangle 13 qui est proroger par un fourreau cylindrique 15 diamétralement fendue 16 sur toute sa longueur, pour former deux ailettes 15a, 15b indépendantes. La fente 16 débouche dans une ouverture circulaire située à la base du rectangle 13 fournissant de la souplesse aux ailettes 15a, 15b, tandis que l’extrémité terminale du fourreau 15 est chanfreinée et se referme sur elles même. On comprend que la cheville 3 est nanti d’un passage cylindrique intégrant des appendices, sur toute sa longueur dont la description sera effectuée plus loin.Figure 1 is a schematic perspective view of a fixing device 1 comprising a screw 2 pre-mounted in a pin 3, capable of instantly fixing a member to a structural element of a vehicle. The view shows only the upper part of the screw 2, while the lower part is introduced into the pin 3 in a captive manner. The upper part of the screw 2 comprises a head 4 extended by a smooth cylindrical sector 5 leading to a collar 6 of limited width and height, extending by a ribbed cylindrical shaft 7 of a diameter identical to that of the smooth sector 5. The lower part of the screw 2 will be described later. The pin 3 comprises a body 8 comprising a cylindrical section 9 comprising diametrically opposed flats 9a over part of its length extending by a thin cylindrical portion 10, and a groove 12 of square section and of length substantially equal to one side of the square, then then being extended by a rectangular plate 13 with a side equal over its length to the diameter of the cylindrical section 10, of thickness less than the side of the square section groove 12. Said rectangle 13 is obtained by truncation on both sides opposite 17. Chamfers 14 are shaped on the two other sides of the rectangle 13 which is extended by a cylindrical sheath 15 diametrically slotted 16 over its entire length, to form two independent fins 15a, 15b. The slot 16 opens into a circular opening located at the base of the rectangle 13 providing flexibility to the fins 15a, 15b, while the terminal end of the sheath 15 is chamfered and closes on themselves. It is understood that the pin 3 is provided with a cylindrical passage integrating appendages, over its entire length, the description of which will be carried out later.
Les figures 2 à 3 sont des vues schématiques en coupe du dispositif de fixation 1 montrant la vis 2 montée dans la cheville 3 en position préalable d’imperdabilité et ladite vis 2 dans sa position montée de fixation d’un organe sur une structure (non représentée sur les figures 2, 3). La figure 2 est la vue de la vis 2 avant montage, dans sa position d’imperdabilité, on voit que le fût striée 7 de la vis 2 est interrompu par une gorge 18 ménagée près de l’extrémité de vis 2 et prolongée par un têton tronqué 19 dont le bout se termine par une surface plane 20. Le fût 7 de la vis 2 est introduit dans le passage cylindrique 28 dont l’ouverture est chanfreinée, pour faciliter l’introduction de ladite vis 2. Le passage cylindrique 28 est un alésage traversant le corps 8 et le fourreau 15 de la cheville 2, ledit fourreau 15 comporte sur une section interne disposée dans une partie interne du fût 7 des ergots 21 en saillie interne. Ces ergots 21 possèdent un chanfrein 22 orienté en direction du corps cylindrique 8 de la cheville 3. Ainsi, lorsque la vis 2 est introduite dans la cheville 3, elle se déplace librement dans le fourreau 15 jusqu’à ce que les ergots 21 glisse sur le têton 19 et écarte simultanément les ailettes 15a, 15b du fourreau 15 fendus sur leurs longueurs, puis se place dans la gorge 18 rendant la vis 2 imperdable puisqu’elle est retenue par les ergots 21. On peut également remarquer que la cheville 3 comporte un dégagement en forme d’embrèvement 23 circulaire. Sur la figure 3, on voit la vis 2 dans sa position de service, a cet effet il suffit que le monteur pousse la tête 4 de la vis 2 avec le pouce suivant la flèche 25 de la figure 2, par exemple pour bloquer l’organe concerné sur la structure du véhicule. Dans cette configuration, le têton tronqué 19 de la vis 2 s’est extrait de l’extrémité du fourreau 15 dont ladite extrémité refermée en chanfrein vient se loger dans la gorge 18 de la vis 2 dans laquelle les ergots 21 étaient logés précédemment. Consécutivement, la collerette 6 de la vis 2 vient se loger dans l’embrèvement 23 circulaire du corps 8 de la cheville 3 en générant un bruit de claquement signifiant que l’assemblage de la vis 2 et de la cheville 3 sont correctement montés signifiant que l’organe concerné est correctement monté sur la structure du véhicule.Figures 2 to 3 are schematic cross-sectional views of the fastening device 1 showing the screw 2 mounted in the pin 3 in the prior captive position and said screw 2 in its mounted position for fixing a member to a structure (not shown in Figures 2, 3). Figure 2 is the view of the screw 2 before assembly, in its captive position, it can be seen that the ribbed shaft 7 of the screw 2 is interrupted by a groove 18 made near the end of the screw 2 and extended by a truncated stud 19, the end of which ends in a flat surface 20. The shaft 7 of the screw 2 is introduced into the cylindrical passage 28, the opening of which is chamfered, to facilitate the introduction of said screw 2. The cylindrical passage 28 is a bore passing through the body 8 and the sleeve 15 of the pin 2, said sleeve 15 comprises on an internal section arranged in an internal part of the shaft 7 lugs 21 projecting internally. These lugs 21 have a chamfer 22 oriented in the direction of the cylindrical body 8 of the peg 3. Thus, when the screw 2 is introduced into the peg 3, it moves freely in the sheath 15 until the lugs 21 slide on the pin 19 and simultaneously spreads the fins 15a, 15b of the sheath 15 split along their lengths, then is placed in the groove 18 making the screw 2 captive since it is retained by the lugs 21. It can also be noted that the pin 3 comprises a clearance in the form of a recess 23 circular. In Figure 3, we see the screw 2 in its service position, for this purpose it suffices that the fitter pushes the head 4 of the screw 2 with the thumb following the arrow 25 of Figure 2, for example to block the component concerned on the structure of the vehicle. In this configuration, the truncated pin 19 of the screw 2 is extracted from the end of the sheath 15 whose said end closed in chamfer is housed in the groove 18 of the screw 2 in which the lugs 21 were housed previously. Consecutively, the flange 6 of the screw 2 comes to be housed in the circular recess 23 of the body 8 of the pin 3 generating a clicking noise signifying that the assembly of the screw 2 and the pin 3 are correctly mounted, signifying that the component concerned is correctly mounted on the structure of the vehicle.
La figure 4 est une vue schématique de face en coupe du dispositif de fixation 1 dans une configuration de montage d’un organe spécifique 26 sur un élément de structure 27 d’un véhicule, selon l'invention. L’organe 26 à monter comporte une ouverture rectangulaire 26a dans laquelle peut pénétrer librement la platine rectangle 13 de la cheville 3. L’épaisseur de l’organe 26 est inférieure à la distance entre le corps et la platine rectangle 13 de la cheville 3, soit sensiblement une distance égale à un coté de la section carrée 12. L’élément de structure 27 comporte un passage cylindrique 29. Pour effectuer le montage de l’organe 26 sur le structure 27, on comprend qu’on introduit la platine rectangle 13 de la cheville 3 dans l’ouverture rectangulaire 26a, la base du corps cylindrique 8 venant en appui sur la surface supérieure de l’organe 26, tandis que la platine rectangle 13 de la cheville 3 vient sous la surface inférieure de l’organe 26. Pour positionner la cheville 3 en prise dans l’organe 26, il suffit de pivoter la cheville 3 d’un quart de tour, ainsi la platine rectangle 13 est bloquée par le croisement de l’ouverture rectangulaire 26a de l’organe 26. Dans cette position, il suffit d’introduire l’extrémité de la cheville 3 dans le passage circulaire 29 de la structure 27, jusqu’à ce que la base de la platine rectangle 13 viennent en appui sur la face de la pièce de structure 27. Dans cette position de mise en place préalable, la tête 4 de la vis 3 est enfoncée par un pouce ou éventuellement par un outil approprié, consécutivement, les ergots 21 de la cheville 3 écartent les ailettes 15a, 15b du fourreau 15 en glissant sur les stries du fût 7 de la vis 2. La tête 4 de la vis 2 est agencée pour venir en appui sur la surface supérieure du corps 8 de la cheville 3. Les ailettes 15a, 15b viennent en appui sur la paroi du passage circulaire 29 et fixe l’organe 26 sur la structure 27 par l’intermédiaire du dispositif de fixation 1. L’écartement des ailettes 15a, 15b a été exagérément effectué sur la figure pour bien faire comprendre l’invention. Le dispositif de fixation 1 permet avantageusement d’assembler rapidement des pièces entre elles puisqu’il n’y a pas de vissage et permet de ce fait de réaliser un gain de temps considérable.FIG. 4 is a schematic cross-sectional front view of the fastening device 1 in a configuration for mounting a specific member 26 on a structural element 27 of a vehicle, according to the invention. The member 26 to be mounted has a rectangular opening 26a into which the rectangular plate 13 of the peg 3 can freely penetrate. The thickness of the member 26 is less than the distance between the body and the rectangular plate 13 of the peg 3 , or substantially a distance equal to one side of the square section 12. The structural element 27 comprises a cylindrical passage 29. To mount the member 26 on the structure 27, it is understood that the rectangular plate is introduced 13 of the pin 3 in the rectangular opening 26a, the base of the cylindrical body 8 bearing on the upper surface of the member 26, while the rectangular plate 13 of the pin 3 comes under the lower surface of the member 26. To position the pin 3 in engagement in the member 26, it suffices to pivot the pin 3 by a quarter turn, thus the rectangular plate 13 is blocked by the crossing of the rectangular opening 26a of the member 26 In this position, it suffices to introduce the end of the pin 3 into the circular passage 29 of the structure 27, until the base of the rectangular plate 13 comes to rest on the face of the structural part. 27. In this position of prior positioning, the head 4 of the screw 3 is driven in by a thumb or possibly by an appropriate tool, consecutively, the lugs 21 of the pin 3 spread the fins 15a, 15b of the sheath 15 by sliding on the grooves of the barrel 7 of the screw 2. The head 4 of the screw 2 is arranged to bear against the upper surface of the body 8 of the pin 3. The fins 15a, 15b bear against the wall of the circular passage 29 and fixes the member 26 on the structure 27 by means of the fixing device 1. The spacing of the fins 15a, 15b has been made exaggeratedly in the figure in order to make the invention clearly understood. The fixing device 1 advantageously makes it possible to quickly assemble the parts together since there is no screwing and therefore makes it possible to save considerable time.
