5 Le dispositif de fixation repéré par 11 sur la figure 6 est utilisé au sein d'un véhicule automobile pour solidariser une pièce rapportée à ce véhicule, telle qu'un bloc optique 12, à une embase horizontale fixe 13 de ce véhicule sans contraindre l'opérateur assurant 10 cette fixation à adopter une position inconfortable. A cet effet, le dispositif 11 comprend un organe de serrage en forme de came 14 s'engageant selon une direction sensiblement horizontale XX+ au sein d'une patte de fixation 16 constituant une face latérale du véhicule 15 en étant solidaire du bloc optique 12. Cet organe 14 est monté rotatif autour de la direction horizontale XX+ entre une position active b dans laquelle il assure le maintien de la patte 16 relativement à l'embase fixe 13 et une position inactive 20 ou neutre a dans laquelle il libère la pièce 12 relativement à l'embrase. Plus précisément, l'organe de serrage 14 illustré sur la figure 2 comprend un support sensiblement cylindrique 17 s'étendant suivant la direction XX+ et dont 25 une extrémité forme une touche de préhension 18 pourvue d'au moins un méplat 19, telle qu'une touche à section hexagonale, et une tête en forme générale de rondelle circulaire 21, montée solidaire en rotation de l'extrémité 20 du support d'axe 17 opposée à la touche 30 18. La rondelle circulaire définie par la tête 21 de l'organe 14 est centrée autour d'un axe CC+ et présente une paroi latérale 22 de section transversale sensiblement constante au contour périphérique circulaire 35 23.5 The fixing device marked by 11 in FIG. 6 is used within a motor vehicle to secure a part attached to this vehicle, such as an optical unit 12, to a fixed horizontal base 13 of this vehicle without constraining the vehicle. operator providing 10 this fixation to adopt an uncomfortable position. To this end, the device 11 comprises a cam-shaped clamping member 14 which engages in a substantially horizontal direction XX + within a fixing lug 16 constituting a lateral face of the vehicle 15 while being integral with the optical unit 12. This member 14 is rotatably mounted around the horizontal direction XX + between an active position b in which it maintains the tab 16 relative to the fixed base 13 and an inactive 20 or neutral position a in which it releases the part 12 relatively at the base. More precisely, the clamping member 14 illustrated in FIG. 2 comprises a substantially cylindrical support 17 extending in the direction XX + and one end of which forms a gripping key 18 provided with at least one flat 19, such that a key with a hexagonal section, and a head in the general shape of a circular washer 21, mounted integral in rotation with the end 20 of the shaft support 17 opposite the key 30 18. The circular washer defined by the head 21 of the member 14 is centered around an axis CC + and has a side wall 22 of substantially constant cross section at the circular peripheral contour 35 23.
2905093 5 Comme visible sur la figure 2, le support 17 de l'organe de serrage 14 s'étend suivant l'axe de symétrie XX+ qui est excentré relativement à l'axe CC+ de la tête 21 de l'organe 14.As can be seen in FIG. 2, the support 17 of the clamping member 14 extends along the axis of symmetry XX + which is eccentric relative to the axis CC + of the head 21 of the member 14.
5 Ainsi, comme mis en évidence sur la figure 5, ce support 17 définit avec le contour périphérique 23 de la tête 21 de l'organe 14 un point haut PH, le plus éloigné de l'axe de symétrie XX+, et un point bas PB, plus proche de l'axe de symétrie XX+ que ne l'est le point haut PH.5 Thus, as demonstrated in FIG. 5, this support 17 defines with the peripheral contour 23 of the head 21 of the member 14 a high point PH, the furthest from the axis of symmetry XX +, and a low point PB, closer to the axis of symmetry XX + than the high point PH.
10 Plus précisément, comme visible en traits pleins sur la figure 5, le point bas PB est un point du contour périphérique 23 de la tête 21 du bouton 14 le plus proche de l'embase 13 dans la position inactive a de l'organe 14 et espacé de cette embase 13 par un espace de 15 coincement 25. D'autre part, le point haut PH est le point périphérique de la tête 21 de l'organe 14 destiné à venir en appui par coincement sur la paroi inférieure 15 de l'embase 13 lorsque l'organe 14 a tourné autour de la 20 direction XX+ à sa position active b , empêchant tout mouvement vertical cu bloc optique 12 relativement à l'embase 13. D'autre part, l'organe 14 comprend deux pions de blocage 24a, 24b, diamétralement opposés relativement à 25 l'axe XX+ et faisant saillie de la face 26 de la tête 21 sur laquelle est fixée l'extrémité 20 du support 17. Chaque pion 24a, 24b comprend au niveau de son extrémité libre deux lames souples 27a, 28a, 27b, 28b séparées par un espace de rapprochement 29a, 29b et 30 définissant chacune un clip 31a, 32a, 31b, 32b, mieux visible sur la figure 4, destiné à venir en appui sur la face 33 de la patte de fixation 16 opposée à l'organe 14 lorsque celui-ci maintient la patte 16 fixée à l'embase 13.10 More precisely, as visible in solid lines in FIG. 5, the low point PB is a point of the peripheral contour 23 of the head 21 of the button 14 closest to the base 13 in the inactive position a of the member 14 and spaced from this base 13 by a wedging space 25. On the other hand, the high point PH is the peripheral point of the head 21 of the member 14 intended to come to rest by wedging on the lower wall 15 of the 'base 13 when the member 14 has rotated around the direction XX + to its active position b, preventing any vertical movement cu optical unit 12 relative to the base 13. On the other hand, the member 14 comprises two pins. blocking 24a, 24b, diametrically opposed relative to the axis XX + and projecting from the face 26 of the head 21 on which is fixed the end 20 of the support 17. Each pin 24a, 24b comprises at its free end two flexible blades 27a, 28a, 27b, 28b separated by a reconciliation space 29a, 29b and 30 each defining a clip 31a, 32a, 31b, 32b, better visible in Figure 4, intended to come to bear on the face 33 of the fixing tab 16 opposite to the member 14 when the latter keeps the tab 16 fixed at the base 13.
2905093 6 Cet organe 14 pourvu de son support d'axe 17, de sa tête 21 et de ses pions 24a, 24b est de préférence constitué d'une seule et même pièce, en un matériau plastique adapté pour être mis en forme par moulage par 5 injection, tel que du polyamide PA6 ou 66. D'autre part, comme mieux visible sur la figure 3, la patte de fixation 16 présente une forme générale de plaque rectangulaire s'étendant verticalement depuis une paroi inférieure horizontale 34 du bloc optique 12 vers 10 le bas du véhicule et est avantageusement moulée avec le bloc optique 12. Cette patte 16 comprend un orifice circulaire de passage 36 du support 17 de l'organe 14 disposé sous l'embase 13 lorsque le bloc optique 12 repose sur celle- 15 ci, et situé par exemple sensiblement au centre de la patte 16, et deux rainures 37a, 37b de guidage des deux pions 24a, 24b lors de la rotation de l'organe 14 relativement à la patte 16 autour de l'axe XX+. Ces rainures 37a, 37b s'étendent suivant un quart 20 de cercle centré autour de l'orifice 36, dont le rayon est sensiblement égal respectivement aux deux distances séparant les pions 24a, 24b du bouton 14 de l'axe XX+' En outre, ces rainures 37a, 37b comprennent respectivement deux extrémités d'engagement 35a, 35b du 25 pion correspondant 24a, 24b formant ensemble une direction sensiblement verticale définissant lorsque les pions 24a, 24b sont engagés dans ces extrémités 35a, 35b, la position inactive a de l'organe 14 visible sur la figure 4.2905093 6 This member 14 provided with its axis support 17, its head 21 and its pins 24a, 24b is preferably made of one and the same part, in a plastic material suitable for being shaped by molding by 5 injection, such as polyamide PA6 or 66. On the other hand, as better visible in FIG. 3, the fixing tab 16 has the general shape of a rectangular plate extending vertically from a horizontal lower wall 34 of the optical unit 12. towards the bottom of the vehicle and is advantageously molded with the optical unit 12. This tab 16 comprises a circular orifice 36 for passage of the support 17 of the member 14 disposed under the base 13 when the optical unit 12 rests on it. Ci, and located for example substantially in the center of the lug 16, and two grooves 37a, 37b for guiding the two pins 24a, 24b during the rotation of the member 14 relative to the lug 16 about the axis XX +. These grooves 37a, 37b extend along a quarter of a circle centered around the orifice 36, the radius of which is substantially equal respectively to the two distances separating the pins 24a, 24b of the button 14 from the axis XX + 'In addition, these grooves 37a, 37b respectively comprise two engagement ends 35a, 35b of the corresponding pin 24a, 24b together forming a substantially vertical direction defining when the pins 24a, 24b are engaged in these ends 35a, 35b, the inactive position a of the organ 14 visible in Figure 4.
30 Sur engagement d'un pion 24a, 24b dans sa rainure 37a, 37b, les parties en biseau de chaque clip 31a, 32a, 31b, 32b longent les parois latérales de la rainure correspondante 37a, 37b, provoquant le rapprochement des deux lames souples 27a, 28a, 27b, 28b de ce pion 24a, 35 24b, jusqu'à ce que les parties de butée des deux clips 2905093 7 31a, 32a, 31b, 32b de ce pion 24a, 24b dépassent la face avant 33 de la patte 33, permettant le dégagement des clips 31a, 32a, 31b, 32b de la rainure 37a, 37b et l'écartement mutuel des deux lames 27a, 28a, 27b, 28b de 5 ce pion 24a, 24b. Chaque rainure 37a, 37b comprend encore à son extrémité opposée à l'extrémité d'engagement 35a, 35b un étranglement 38a, 38b formant un logement d'ancrage 39a, 39b de la paire de clips 31a, 32a, 31b, 32b du pion 10 correspondant 24a, 24b. Un effort de rotation suffisant exercé sur l'organe 14 dans un sens de rapprochement des pions 24a, 24b de leurs logements respectifs 39a, 39b provoquera au niveau de l'étranglement 38a, 38b un rapprochement des lames 15 souples 27a, 28a, 27b, 28b et l'écartement l'une de l'autre de ces lames 27a, 28a, 27b, 28b une fois le logement 39a, 39b du pion 24a, 24b atteint, l'étranglement 38a, 38b bloquant ensuite toute rotation du bouton 14 tendant à éloigner les pions 24a, 24b de 20 leurs logements respectifs 39a, 39b. Les deux logements de réception 39a, 39b des rainures 37a, 37b définissent lorsque les pions 24a, 24b de l'organe 14 y sont engagés, la position active b de l'organe 14, pour laquelle le point haut PH de la tête 21 25 de l'organe 14 vient à être coincé sous l'embase 13 du véhicule, fixant la patte 16 relativement à l'embase 13, et pour laquelle les deux pions 24a, 24b de l'organe 14 définissent une direction horizontale comme visible sur la figure 2.On engagement of a pin 24a, 24b in its groove 37a, 37b, the bevelled parts of each clip 31a, 32a, 31b, 32b run along the side walls of the corresponding groove 37a, 37b, causing the two flexible blades to come together. 27a, 28a, 27b, 28b of this pin 24a, 35 24b, until the stop parts of the two clips 2905093 7 31a, 32a, 31b, 32b of this pin 24a, 24b exceed the front face 33 of the tab 33, allowing the release of the clips 31a, 32a, 31b, 32b from the groove 37a, 37b and the mutual separation of the two blades 27a, 28a, 27b, 28b of this pin 24a, 24b. Each groove 37a, 37b also comprises at its end opposite to the engagement end 35a, 35b a constriction 38a, 38b forming an anchoring housing 39a, 39b of the pair of clips 31a, 32a, 31b, 32b of the pin 10 corresponding 24a, 24b. A sufficient rotational force exerted on the member 14 in a direction of approach of the pins 24a, 24b of their respective housings 39a, 39b will cause at the level of the constriction 38a, 38b an approximation of the flexible blades 27a, 28a, 27b, 28b and the distance from one another of these blades 27a, 28a, 27b, 28b once the housing 39a, 39b of the pin 24a, 24b has been reached, the constriction 38a, 38b then blocking any rotation of the button 14 tending moving the pins 24a, 24b away from their respective housings 39a, 39b. The two receiving housings 39a, 39b of the grooves 37a, 37b define when the pins 24a, 24b of the member 14 are engaged therein, the active position b of the member 14, for which the high point PH of the head 21 25 of the member 14 comes to be wedged under the base 13 of the vehicle, fixing the tab 16 relative to the base 13, and for which the two pins 24a, 24b of the member 14 define a horizontal direction as visible on the figure 2.
30 En outre, la paroi inférieure 34 du bloc optique 12 comprend un plot pilote 41 mieux visible sur la figure 3, facilitant la mise en place du bloc optique 12 selon la direction YY+ de la figure 6 sur l'embase 13, par engagement de ce plot 41 au sein d'une entaille 35 longiligne 42 visible sur la figure 7, formée dans 2905093 8 l'embase 13 et s'étendant à partir du bord frontal avant 43 de l'embase 13 selon la direction XX+. On détaille ci-dessous en référence aux figures 7 à 10, les étapes de fixation selon la direction non 5 critique XX+ du bloc optique 12 à l'embase 13 au moyen du dispositif selon l'invention. Il est à noter que l'organe de serrage 14 représenté sur ces figures diffère de l'organe 14 des figures 2 à 4 uniquement en ce que dans sa position 10 inactive a (figure 7), les pions 24a, 24b de cet organe 14 définissent une direction sensiblement horizontale et que dans sa position active b (figure 9), ces pions 24a, 24b s'étendent selon une direction sensiblement verticale.In addition, the lower wall 34 of the optical unit 12 comprises a pilot pad 41 better visible in FIG. 3, facilitating the positioning of the optical unit 12 in the YY + direction of FIG. 6 on the base 13, by engaging the base 13. this stud 41 within an elongated notch 42 visible in FIG. 7, formed in the base 13 and extending from the front frontal edge 43 of the base 13 in the direction XX +. With reference to FIGS. 7 to 10, the steps for fixing in the non-critical direction XX + of the optical unit 12 to the base 13 by means of the device according to the invention are detailed below. It should be noted that the clamping member 14 shown in these figures differs from the member 14 of Figures 2 to 4 only in that in its inactive position a (Figure 7), the pins 24a, 24b of this member 14 define a substantially horizontal direction and that in its active position b (Figure 9), these pins 24a, 24b extend in a substantially vertical direction.
15 Afin d'assurer la solidarisation du bloc optique 12 à l'embase 13, un opérateur dispose ce bloc optique 12 sur l'embase 13 et rapproche horizontalement la patte 16 du bord frontal 43 de l'embase 13, ce rapprochement étant guidé par le plot pilote 41 engagé dans l'entaille 42 de 20 l'embase 16. Par la suite, l'opérateur positionne l'organe de serrage 14 du dispositif en vis-à-vis de la face arrière 44 de la patte 16 et exerce un effort tendant à rapprocher l'organe 14 de l'orifice 36 de la patte de 25 fixation 16 jusqu'à ce que les pions 24a, 24b s'encliquettent dans les extrémités d'engagement 35a, 35b des rainures appropriées 37a, 37b, provoquant dans le même temps l'insertion du support d'axe 17 au sein de l'orifice 36 formé dans la patte 16.15 In order to secure the optical unit 12 to the base 13, an operator places this optical unit 12 on the base 13 and horizontally brings the tab 16 closer to the front edge 43 of the base 13, this approach being guided by the pilot stud 41 engaged in the notch 42 of the base 16. Subsequently, the operator positions the clamping member 14 of the device opposite the rear face 44 of the tab 16 and exerts a force tending to bring the member 14 closer to the orifice 36 of the fixing lug 16 until the pins 24a, 24b engage in the engagement ends 35a, 35b of the appropriate grooves 37a, 37b, at the same time causing the insertion of the axle support 17 within the orifice 36 formed in the tab 16.
30 A ce stade, :L'organe de serrage 14 occupe sa position inactive a de la figure 7 et sa touche de préhension 18 fait saillie de la face avant 33 de la patte 16. Comme visible sur la figure 8, dans cette position 35 inactive a , la tête 21 du bouton 14 est séparée de la 2905093 9 paroi inférieure 15 de l'embase 13 par l'espace de coincement précité 25 et le point périphérique de la tête 21 du bouton 14 le plus proche de l'embase est le point bas PB.At this stage,: The clamping member 14 occupies its inactive position a of FIG. 7 and its gripping key 18 protrudes from the front face 33 of the tab 16. As can be seen in FIG. 8, in this position 35 inactive a, the head 21 of the button 14 is separated from the lower wall 15 of the base 13 by the aforementioned jamming space 25 and the peripheral point of the head 21 of the button 14 closest to the base is the low point PB.
5 L'opérateur exerce ensuite un effort de rotation repéré par la flèche F1, sur la touche de préhension 18 de l'organe 14, autour de l'axe XX+, dans le sens de rapprochement du point haut PH de l'embase 13, comme visible sur la figure 9.5 The operator then exerts a rotational force identified by the arrow F1, on the gripping key 18 of the member 14, around the axis XX +, in the direction of approach to the high point PH of the base 13, as visible in figure 9.
10 Lors de cette rotation, les pions 24a, 24b de l'organe 14 translatent dans leurs rainures respectives 37a, 37b depuis l'extrémité d'engagement 35a, 35b jusqu'à l'étranglement 38a, 38b de la rainure concernée 35a, 35b. Dans le même temps, le point haut PH de la tête 21 15 de l'organe 14 se rapproche de la paroi inférieure 15 de l'embase 13. L'opérateur poursuit ensuite son effort de rotation dans le même sens, tel qu'illustré par la flèche F2 de la figure 9 afin de bloquer les pions 24a, 24b dans leur 20 logement d'ancrage 39a, 39b et verrouiller ainsi l'organe de serrage 14 dans sa position active b. Lorsque les pions 24a, 24b arrivent en fin de course après rotation de l'excentrique 14, le point haut PH de la tête 21 du bouton 14 est en appui sous l'embase 25 13, comme représenté sur la figure 10, étant donné que la distance séparant l'axe XX+ du point haut PH est sensiblement supérieure à la distance séparant cet axe XX+ de la paroi inférieure 15 de l'embase 13. L'organe 14 dans sa position active b définit 30 avec la patte de fixation 16 et la paroi inférieure 34 du bloc optique 12, une pince exerçant un effort de compression vertical, sans jeu, sur l'embase 13, empêchant tout mouvement de l'ensemble bloc optique 12, patte de fixation 16 et organe 14 relativement à cette 35 embase 13.During this rotation, the pins 24a, 24b of the member 14 translate in their respective grooves 37a, 37b from the engagement end 35a, 35b to the constriction 38a, 38b of the relevant groove 35a, 35b . At the same time, the high point PH of the head 21 15 of the member 14 approaches the lower wall 15 of the base 13. The operator then continues his force of rotation in the same direction, as illustrated. by arrow F2 in FIG. 9 in order to block the pins 24a, 24b in their anchoring housing 39a, 39b and thus lock the clamping member 14 in its active position b. When the pins 24a, 24b reach the end of their travel after rotation of the eccentric 14, the high point PH of the head 21 of the button 14 is supported under the base 25 13, as shown in FIG. 10, given that the distance separating the axis XX + from the high point PH is substantially greater than the distance separating this axis XX + from the lower wall 15 of the base 13. The member 14 in its active position b defines 30 with the fixing lug 16 and the lower wall 34 of the optical unit 12, a clamp exerting a vertical compressive force, without play, on the base 13, preventing any movement of the optical unit 12, fixing tab 16 and member 14 assembly relative to this base 13.
2905093 10 Par conséquent, une fixation verticale du bloc optique 12 relativement à l'embase 13 est obtenue par une manipulation de l'organe de serrage 14 selon une direction sensiblement horizontale et à partir d'une face 5 latérale 33 du véhicule, qui évite à l'opérateur d'adopter une posture inconfortable. D'autre part, les étranglements 38a, 38b des rainures 37a, 37b constituent ensemble un système empêchant toute rotation accidentelle de l'organe 14 à sa 10 position inactive a et ainsi la désolidarisation du bloc optique 12 relativement à l'embase 13. Dans le même but, les clips 31a, 32a, 31b, 32b des pions 24a, 24b du bouton 14 servent d'arrêt en translation de l'organe 14 suivant la direction XX+.Consequently, a vertical fixing of the optical unit 12 relative to the base 13 is obtained by manipulating the clamping member 14 in a substantially horizontal direction and from a side face 33 of the vehicle, which avoids the operator to adopt an uncomfortable posture. On the other hand, the constrictions 38a, 38b of the grooves 37a, 37b together constitute a system preventing any accidental rotation of the member 14 to its inactive position a and thus the separation of the optical unit 12 relative to the base 13. In the same purpose, the clips 31a, 32a, 31b, 32b of the pins 24a, 24b of the button 14 serve as a stop in translation of the member 14 in the direction XX +.
15 D'autre part, par comparaison au dispositif connu de la figure 1, le dispositif de l'invention permet de remplacer l'ensemble à vis, insert et trou au sein du bloc optique, par un organe de serrage obtenu par moulage et une patte de fixation moulée dans le bloc optique, 20 diminuant ainsi les coûts de fabrication.On the other hand, by comparison with the known device of FIG. 1, the device of the invention makes it possible to replace the screw, insert and hole assembly within the optical unit, by a clamping member obtained by molding and a mounting tab molded into the optical unit, thus reducing manufacturing costs.
