Description

Dispositif de protection provisoire à verrou pivotant Temporary protection device with pivoting latch
La présente invention se rapporte à un dispositif d'écartement provisoire d'un élément ouvrant sur un élément fixe d'une carrosserie d'un véhicule automobile.The present invention relates to a device temporarily spacing an element opening on a fixed element of a body of a motor vehicle.
Avant le rattachement définitif d'un élément ouvrant, tel qu'une porte, un capot, ou un hayon, entre autres, sur un élément fixe d'une carrosserie d'un véhicule automobile, il est généralement procédé à des étapes d'application d'un ou plusieurs revêtements, tels que des revêtements de protection ou l'application d'une couche de peinture. Lors de tels traitements, ces éléments ouvrants ne sont pas encore équipés de dispositifs de fermeture définitifs, par exemple des serrures.Before the definitive attachment of an opening element, such as a door, a hood, or a hatchback, among others, to a fixed element of a bodywork of a motor vehicle, it is generally proceeded to application steps one or more coatings, such as protective coatings or the application of a paint layer. During such treatments, these opening elements are not yet equipped with definitive closing devices, for example locks.
Pour cette raison, il est prévu des dispositifs d'écartement provisoire qui permettent de maintenir un élément ouvrant dans une position pseudo-fermée par rapport à l'élément fixe auquel il doit être rattaché.For this reason, temporary spacers are provided which maintain an opening member in a pseudo-closed position relative to the fixed member to which it is to be attached.
Le document FR 2 889 227 décrit un dispositif d'écartement provisoire comprenant, d'une part, une platine de fixation destinée à l'ancrage du dispositif dans l'élément fixe, et d'autre part, un corps rattaché à la platine de fixation et formant une butée apte à servir d'appui à l'élément ouvrant. La platine de fixation comprend au moins deux organes fixation formant becs, l'un au moins étant monté mobile par rapport à la platine de fixation de manière à pouvoir passer alternativement d'une position de retrait dans laquelle la plus petite distance entre les organes de fixation est minimale, à une position d'engagement dans laquelle la plus petite distance entre les organes de fixation est maximale.The document FR 2 889 227 describes a temporary spacing device comprising, on the one hand, a fixing plate intended for anchoring the device in the fixed element, and on the other hand, a body attached to the plate of fixing and forming a stop capable of serving as a support for the opening element. The fixing plate comprises at least two fastener forming members, at least one being mounted movably relative to the fixing plate so as to be able to pass alternately from a retracted position in which the smallest distance between the fastening members fixing is minimal, at an engagement position in which the smallest distance between the fasteners is maximum.
Ainsi, un tel dispositif permet une fixation et un démontage plus simple et plus rapide par clipsage, sans nécessiter l'utilisation d'outils supplémentaires adaptés.Thus, such a device allows attachment and disassembly simpler and faster clipping, without requiring the use of additional tools adapted.
Néanmoins, un tel dispositif d'écartement provisoire est en définitive limité à des applications moyennement chargées, du fait que les efforts de traction passent par le clip de maintien, et ne peut pas par exemple être employé avec des véhicules lourds du type camion.Nevertheless, such a temporary spacing device is ultimately limited to moderately loaded applications, because the traction forces pass through the retaining clip, and can not for example be used with heavy vehicles of the truck type.
La présente invention a pour but de pallier l'inconvénient évoqué précédemment, et consiste pour cela en un verrou pour dispositif d'écartement provisoire d'un élément ouvrant sur un élément fixe d'une carrosserie d'un véhicule automobile, ledit verrou comprenant, d'une part, des moyens de blocage conçus de manière à pouvoir se déformer de manière élastique sous l'action des contraintes exercées par l'élément ouvrant, et d'autre part, un socle sensiblement cylindrique muni de moyens de fixation activables par pivotement du socle autour de son axe. Selon un mode de réalisation préféré de l'invention, les moyens de fixation comprennent au moins un élément de fixation faisant saillie de la surface latérale du socle.The present invention aims to overcome the drawback mentioned above, and consists of a lock for temporary spacing device of a member opening on a fixed element of a body of a motor vehicle, said lock comprising, on the one hand, means of blocking designed to be elastically deformable under the action of the stresses exerted by the opening member, and secondly, a substantially cylindrical base provided with fixing means activatable by pivoting the base around its axis. According to a preferred embodiment of the invention, the fixing means comprise at least one fastening element projecting from the lateral surface of the base.
Avantageusement, au moins un élément de fixation est constitué par une nervure longitudinale. Avantageusement encore, au moins un élément de fixation est constitué par une nervure transversale. La nervure transversale peut être d'épaisseur variable, et est de préférence d'épaisseur croissante dans le sens de pivotement en vue de la fixation.Advantageously, at least one fastening element is constituted by a longitudinal rib. Advantageously, at least one fastening element is constituted by a transverse rib. The transverse rib may be of variable thickness, and is preferably of increasing thickness in the pivoting direction for attachment.
Préférentiellement encore, les moyens de fixation comprennent au moins un ergot externe transversal, diamétralement opposé à la nervure transversale, et ménagé du côté opposé à l'extrémité d'introduction du socle.Preferably, the fixing means comprise at least one transverse external lug, diametrically opposite to the transverse rib, and arranged on the opposite side to the insertion end of the base.
La présente invention se rapporte également à une embase comprenant des moyens d'emboîtement permettant son ancrage dans un élément fixe d'une carrosserie d'un véhicule automobile, un logement définissant une section d'introduction permettant l'insertion du socle d'un verrou selon l'invention, et des moyens de liaison conçus de manière à coopérer avec les moyens de fixation dudit verrou.The present invention also relates to a base comprising interlocking means for anchoring it in a fixed element of a bodywork of a motor vehicle, a housing defining an insertion section allowing insertion of the base of a lock. according to the invention, and connecting means designed to cooperate with the fastening means of said latch.
Ainsi, contrairement à l'état de la technique exposée précédemment, l'objectif de l'invention est atteint grâce au fait que les efforts que doivent transmettre les moyens de blocage à la carrosserie via l'embase ne sollicitent pas les moyens de fixation eux-mêmes. En fait, le rattachement du verrou à l'embase est obtenu à la suite d'un mouvement d'introduction en translation du socle dans le logement, puis d'un mouvement de fixation en rotation dans le logement, cette combinaison permettant de découpler la transmission d'efforts de la fonction « verrouillage » à proprement parler.Thus, contrary to the state of the art explained above, the object of the invention is achieved thanks to the fact that the efforts that the blocking means must transmit to the bodywork via the base do not require the means of fixing them. -Same. In fact, the attachment of the latch to the base is obtained following a movement of introduction in translation of the base in the housing, then a rotational fixing movement in the housing, this combination to decouple the transmission of efforts of the "locking" function itself.
Cette fixation est donc particulièrement appréciable car, d'une part, elle ne nécessite l'utilisation d'aucun outil, et d'autre part, la tenue mécanique proposée par le dispositif d'écartement provisoire après verrouillage est très élevée. Avantageusement, les moyens de liaison comprennent au moins une rainure longitudinale ménagée dans le logement. Avantageusement encore, les moyens de liaison comprennent une cloison de liaison du côté de la section d'introduction du logement, ladite cloison de liaison s'étendant parallèlement à l'axe du logement et présentant une ouverture transversale. Préférentiellement, les moyens d'emboîtement comprennent au moins une cloison d'ancrage s'étendant parallèlement à l'axe du logement, du côté opposée à la section d'introduction du logement.This attachment is particularly significant because, firstly, it does not require the use of any tool, and secondly, the mechanical strength proposed by the temporary spacing device after locking is very high. Advantageously, the connecting means comprise at least one longitudinal groove formed in the housing. Advantageously, the connecting means comprise a connecting wall on the side of the housing introduction section, said connecting partition extending parallel to the axis of the housing and having a transverse opening. Preferably, the interlocking means comprise at least one anchoring wall extending parallel to the axis of the housing, on the opposite side to the housing introduction section.
Préférentiellement encore, les moyens d'emboîtement comprennent au moins un pion d'ancrage disposé perpendiculairement à la cloison d'ancrage.Preferably, the interlocking means comprise at least one anchor pin disposed perpendicularly to the anchor wall.
Enfin, la présente invention se rapporte également à un dispositif d'écartement provisoire d'un élément ouvrant sur un élément fixe d'une carrosserie d'un véhicule automobile, caractérisé en ce qu'il comprend un verrou et une embase selon l'invention. Ainsi, un tel dispositif d'écartement provisoire est très avantageux puisqu'il peut être utilisé aussi bien pour des véhicules légers que pour des véhicules lourds.Finally, the present invention also relates to a temporary spacing device of an element opening on a fixed element of a bodywork of a motor vehicle, characterized in that it comprises a latch and a base according to the invention. . Thus, such a temporary spacing device is very advantageous since it can be used for both light vehicles and heavy vehicles.
De plus, même si ce dispositif d'écartement provisoire est constitué de deux éléments distincts, il n'en demeure pas moins que son transport, son stockage et sa gestion sont aisés puisqu'il peut être moulé et livré au client en une seule pièce monobloc, le verrou et l'embase étant alors reliés par des liens sécables pouvant être rompus au dernier moment.In addition, even if this temporary spacing device consists of two separate elements, the fact remains that its transport, storage and management are easy since it can be molded and delivered to the customer in one piece monoblock, the lock and the base being then connected by breakable links that can be broken at the last moment.
La mise en œuvre de l'invention sera mieux comprise à l'aide de la description détaillée qui est exposée ci-dessous en regard du dessin annexé dans lequel :The implementation of the invention will be better understood with the aid of the detailed description which is set out below with reference to the appended drawing in which:
La figure 1 est une vue en perspective d'un dispositif d'écartement provisoire selon l'invention, avant rattachement du verrou à l'embase ;Figure 1 is a perspective view of a temporary spacer device according to the invention, before attaching the lock to the base;
La figure 2 est une vue de détail de la figure 1 montrant le positionnement du verrou avant insertion du socle dans l'embase ; La figure 3 est une vue schématique en perspective d'un dispositif d'écartement provisoire selon l'invention avant assemblage ;Figure 2 is a detail view of Figure 1 showing the positioning of the lock before insertion of the base in the base; Figure 3 is a schematic perspective view of a temporary spacing device according to the invention before assembly;
La figure 4 est une vue similaire à la figure 3, une fois que l'embase a été fixée dans un élément fixe de la carrosserie d'un véhicule automobile ;Figure 4 is a view similar to Figure 3, once the base has been fixed in a fixed element of the body of a motor vehicle;
La figure 5 est une vue similaire à la figure 4, une fois que le verrou est fixé dans l'embase ; La figure 6 est une vue de détail de la figure 5, montrant le positionnement du verrou par rapport à l'embase une fois fixé ;Figure 5 is a view similar to Figure 4, once the lock is fixed in the base; Figure 6 is a detail view of Figure 5, showing the positioning of the lock relative to the base once fixed;
La figure 7 est une vue similaire à la figure 5, une fois que l'élément ouvrant est en position pseudo-fermée. Un dispositif 1 d'écartement provisoire selon l'invention, tel que représenté aux figures 1 à 7, se décompose en une embase 2 monobloc et un verrou 3 monobloc en matière plastique, par exemple à base de polyamide, de façon à pouvoir résister aux températures élevées auxquelles ledit dispositif est confronté lors des étapes de peinture, tout en offrant des propriétés d'élasticité et des coûts de fabrication relativement faibles.Figure 7 is a view similar to Figure 5, once the opening element is in the pseudo-closed position. A temporary spacing device 1 according to the invention, as represented in FIGS. 1 to 7, is decomposed into a monoblock base 2 and a monoblock lock 3 made of plastics material, for example based on polyamide, so as to be able to withstand high temperatures at which said device is confronted during the painting steps, while offering relatively low elasticity properties and manufacturing costs.
Plus précisément, l'embase 2 comprend une platine de fixation 4 destinée à être disposée parallèlement au plan dans lequel est contenu un élément fixe 5 correspondant de carrosserie d'un véhicule automobile.More specifically, the base 2 comprises a fixing plate 4 intended to be arranged parallel to the plane in which is contained a fixed element 5 corresponding body of a motor vehicle.
Cette platine de fixation 4 comprend une partie arrière 6, et une partie avant formant un logement 7 discoïde délimitant une section d'introduction 8.This mounting plate 4 comprises a rear portion 6, and a front portion forming a disc-shaped housing 7 delimiting an insertion section 8.
Plus précisément, et comme représenté à la figure 2, le logement 7 comprend une bordure présentant un profil 7a parfaitement circulaire à l'avant et sur une partie de l'arrière, et un profil 7b sensiblement droit à l'arrière. La section d'introduction 8 présente de ce fait une géométrie sensiblement circulaire, sauf au niveau de la jonction des profils 7a et 7b où un coin 7c est ménagé.More specifically, and as shown in Figure 2, the housing 7 comprises a border having a perfectly circular profile 7a at the front and a portion of the rear, and a substantially straight profile 7b at the rear. The introductory section 8 thus has a substantially circular geometry, except at the junction of the profiles 7a and 7b where a wedge 7c is formed.
Une cloison de liaison 9, à la base de laquelle est ménagée une ouverture tranversale 10, fait orthogonalement saillie de la platine de fixation 4 du côté de la section d'introduction 8, au niveau de la jonction entre la partie arrière 6 et le logement 7.A connecting wall 9, at the base of which is formed a transverse opening 10, orthogonally protrudes from the fixing plate 4 on the side of the insertion section 8, at the junction between the rear portion 6 and the housing 7.
Par ailleurs, la platine de fixation 4 est équipée de moyens d'emboîtement constitués, d'une part, d'une cloison d'ancrage 11 réalisée sous la forme d'une portion de cylindre, et d'autre part, de deux pions d'ancrage 12 formant becs.Furthermore, the mounting plate 4 is equipped with interlocking means consisting, on the one hand, of an anchoring wall 11 made in the form of a cylinder portion, and on the other hand, of two pieces anchor 12 forming nozzles.
Plus précisément, la cloison d'ancrage 11 fait orthogonalement saillie du côté opposée à la section d'introduction 8, en arrière du logement 7.More specifically, the anchor wall 11 orthogonally protrudes from the opposite side to the insertion section 8, behind the housing 7.
Les pions d'ancrage 12 sont ménagés dans la platine de fixation 4 et dépassent de la partie arrière 6. Ces pions d'ancrage 12 sont disposés parallèlement à la platine de fixation 4, du côté opposée à la section d'introduction 8. Comme représenté plus particulièrement à la figure 2, une rainure longitudinale 13 est ménagée dans la surface latérale interne du profil 7a du logement 7, face à la cloison d'ancrage 11.The anchoring pins 12 are formed in the fixing plate 4 and protrude from the rear part 6. These anchoring pins 12 are arranged parallel to the fixing plate 4, on the opposite side to the insertion section 8. As shown more particularly in FIG. 2, a longitudinal groove 13 is formed in the internal lateral surface of the profile 7a of the housing 7, facing the anchoring wall 11.
Le verrou 2 comprend schématiquement un socle 14 surmonté de moyens de blocage.The latch 2 schematically comprises a base 14 surmounted by locking means.
Plus précisément, le socle 14 présente une surface latérale 15 de laquelle fait saillie, d'une part, une nervure longitudinale 16, et d'autre part, une nervure transversale 17 disposée entre la nervure longitudinale 16 et l'extrémité d'introduction 18 dudit socle 14. La nervure transversale 17 est d'épaisseur croissante radialement, et présente un épaulement externe 17a maximal conçu de manière à ce que la distance minimale séparant l'axe du socle 14 dudit l'épaulement externe 17a soit légèrement supérieure au diamètre de la section d'introduction 8.More specifically, the base 14 has a lateral surface 15 from which protrudes, on the one hand, a longitudinal rib 16, and on the other hand, a transverse rib 17 disposed between the longitudinal rib 16 and the insertion end 18. of said base 14. The transverse rib 17 is of radially increasing thickness, and has a maximum external shoulder 17a designed so that the minimum distance separating the axis of the base 14 from the outer shoulder 17a is slightly greater than the diameter of the the introductory section 8.
La nervure longitudinale 16 possède une longueur supérieure à l'épaisseur du logement 7.The longitudinal rib 16 has a length greater than the thickness of the housing 7.
Le socle 14 présente, du côté opposé à son extrémité d'introduction 18, un ergot externe 27 transversal diamétralement opposé à la nervure transversale 17.The base 14 has, on the opposite side to its insertion end 18, an external transverse lug 27 diametrically opposed to the transverse rib 17.
Le socle 14 et l'ergot externe 27 sont surmontés par une paroi 19 sensiblement triangulaire disposée parallèlement à l'axe du socle 14, et une paroi de fond 30 perpendiculaire à ladite paroi 19. Un support 20 surplombe lesdites paroi 19 et paroi de fond 30, et est disposée perpendiculairement à celles-ci. Une languette 21 surmonte le support 20.The base 14 and the external lug 27 are surmounted by a substantially triangular wall 19 disposed parallel to the axis of the base 14, and a bottom wall 30 perpendicular to said wall 19. A support 20 overhangs said wall 19 and bottom wall 30, and is disposed perpendicular thereto. A tongue 21 overcomes the support 20.
Plus précisément, la languette 21 présente une face équipée d'un nez 22 faisant saillie sur une partie de sa longueur, et son autre face est rattachée au support 20 par l'intermédiaire d'un pont 23. La languette 21 est inclinée de telle façon qu'elle penche vers le support 20. La languette 21 et le pont 23 constituent les moyens de blocage.More specifically, the tongue 21 has a face equipped with a nose 22 projecting over a portion of its length, and its other face is attached to the support 20 via a bridge 23. The tongue 21 is inclined such it leans towards the support 20. The tongue 21 and the bridge 23 constitute the locking means.
La présente invention ne portant pas sur les moyens de blocage proprement dits, l'homme du métier est renvoyé pour plus de précision à la lecture des documents FR 2 885 633, FR 2 885 634 et FR 2 885 635, qui décrivent comment sont aménagés lesdits moyens de blocage présentés par le verrou 3. Le principal avantage de prévoir des moyens de blocage aptes à se déformer de manière élastique permet d'absorber les chocs ayant lieu avec l'élément ouvrant. De cette manière, la résistance aux efforts est grandement améliorée et toute déformation de l'élément ouvrant, ou rupture du dispositif d'écartement provisoire à la suite d'un choc, est évitée.The present invention does not relate to the actual blocking means, the person skilled in the art is referred for more precision to the reading of documents FR 2 885 633, FR 2 885 634 and FR 2 885 635, which describe how are arranged said locking means presented by the latch 3. The main advantage of providing resiliently deformable locking means is to absorb shocks occurring with the opening member. In this way, the resistance to the efforts is greatly improved and any deformation of the opening element, or rupture of the temporary spacing device after an impact, is avoided.
En se reportant aux figures 3 à 7, il est possible de constater que le personnel souhaitant installer le dispositif 1 commence par positionner l'embase 2 dans une zone aménagée de l'élément fixe 5 dans laquelle ont été découpés deux alésages arrière 25 et un alésage avant 26.Referring to FIGS. 3 to 7, it can be seen that the personnel wishing to install the device 1 begin by positioning the base 2 in a fitted zone of the fixed element 5 in which two rear bores 25 and one front bore 26.
Le personnel présente tout d'abord l'embase 2 de façon à ce que les deux pions 12 soient dirigés vers l'élément fixe 5, et dans un plan perpendiculaire à celui-ci. L'écartement entre les deux pions 12 est choisi de manière à ce que la distance les séparant soit sensiblement égale à la distance mesurée entre les deux alésages arrière 25.The personnel first presents the base 2 so that the two pins 12 are directed towards the fixed element 5, and in a plane perpendicular thereto. The spacing between the two pins 12 is chosen so that the distance between them is substantially equal to the distance measured between the two rear bores 25.
Ce faisant, il est alors possible d'introduire chaque pion 12 dans l'alésage arrière 25 qui lui correspond, puis de faire pivoter l'embase 2 de façon à ce que la platine de fixation 4 vienne au contact de l'élément 5.In doing so, it is then possible to introduce each peg 12 into the corresponding rear bore 25 and then to pivot the base 2 so that the fixing plate 4 comes into contact with the element 5.
L'écartement entre la cloison d'ancrage 11 et les deux pions 12 est choisi de manière à ce que la cloison d'ancrage 11 vienne automatiquement se loger dans l'alésage avant 26 lorsque les pions 12 sont insérés dans les alésages arrière 25. L'embase 2 est enfin translatée vers l'arrière jusqu'à ce que les pions 12 et la cloison d'ancrage 11 viennent respectivement en butée contre la bordure des alésages arrière 25 et la bordure de l'alésage avant 26. La section d'introduction 8 est alors parfaitement dégagée et peut de ce fait être traversée par le socle 14 du verrou 3. II est ensuite procédé à l'introduction du verrou 3 dans l'embase 2, comme représenté plus spécialement à la figure 2.The spacing between the anchor wall 11 and the two pins 12 is chosen so that the anchor wall 11 automatically comes to be housed in the front bore 26 when the pins 12 are inserted into the rear bores 25. The base 2 is finally translated rearward until the pins 12 and the anchor wall 11 respectively abut against the edge of the rear bores 25 and the edge of the bore before 26. The section introduction 8 is then perfectly disengaged and can therefore be traversed by the base 14 of the latch 3. It is then proceeded to the introduction of the latch 3 in the base 2, as shown more specifically in Figure 2.
Pour cela, le verrou 3 est positionné de façon à ce que l'épaulement externe 17a de la nervure tranversale 17 soit disposé à l'aplomb du coin 7c du logement 7. Ce faisant, le verrou 3 peut être translaté vers le bas de façon à venir s'emboîter dans le logement 7.For this, the lock 3 is positioned so that the outer shoulder 17a of the transverse rib 17 is disposed vertically above the wedge 7c of the housing 7. In doing so, the lock 3 can be translated downwardly so that to come and fit in housing 7.
Comme représenté aux figures 5 et 6, il ne reste plus alors qu'à faire pivoter le verrou de 90° dans le sens trigonométrique jusqu'à ce que la nervure longitudinale 16 vienne se loger dans la rainure longitudinale 13 correspondante. Il doit être bien compris que ce pivotement est rendu possible grâce au fait que le matériau choisi pour réaliser le verrou 3 et l'embase 2 permet des déformations élastiques au niveau de la nervure longitudinale 16, cette dernière recouvrant sa forme originelle une fois logée dans la rainure longitudinale 13.As shown in Figures 5 and 6, it then remains only to rotate the lock 90 ° in the trigonometric direction until the longitudinal rib 16 is housed in the corresponding longitudinal groove 13. It should be understood that this pivoting is made possible by the fact that the material chosen to produce the lock 3 and the base 2 allows elastic deformations at the longitudinal rib 16, the latter covering its original shape once housed in the longitudinal groove 13.
Ce faisant, la nervure transversale 17 se retrouve sous le logement 7, et l'ergot externe 27 vient se loger dans l'ouverture transversale 10 jusqu'à venir en butée contre la cloison de liaison 9.In doing so, the transverse rib 17 is found under the housing 7, and the external lug 27 is housed in the transverse opening 10 until it abuts against the connecting partition 9.
Plus précisément, le verrou 3 est alors parfaitement fixé dans l'embase 2 puisque, outre le fait qu'il est maintenu en position grâce à la nervure longitudinale 16 emboîtée dans la rainure longitudinale 13, ce verrou 3 est, d'une part, bloqué en translation grâce à l'ergot externe 27 disposé dans l'ouverture transversale 10, et d'autre part, empêché de basculer en arrière et en avant grâce, respectivement, à la paroi de fond 30 qui vient en butée contre la cloison 9, et à l'ergot externe 27 disposé dans l'ouverture transversale 10.More specifically, the latch 3 is then perfectly fixed in the base 2 since, besides the fact that it is held in position by virtue of the longitudinal rib 16 fitted into the longitudinal groove 13, this latch 3 is, on the one hand, locked in translation thanks to the external lug 27 disposed in the transverse opening 10, and secondly, prevented from tilting backwards and forwards thanks, respectively, to the bottom wall 30 which abuts against the partition 9 , and the external pin 27 disposed in the transverse opening 10.
Cependant, il doit être bien compris que, d'une part, la cloison d'ancrage 11 peut également constituer une butée à l'égard du socle 14 permettant d'empêcher tout basculement vers l'avant du verrou 3, et d'autre part, la nervure transversale 17, en fonction de son positionnement le long de la surface latérale 15, peut venir en butée contre le profil 7a du logement 7 en cas de basculement vers l'arrière ou de translation vers le haut dudit verrou 3.However, it should be understood that, on the one hand, the anchor wall 11 may also constitute an abutment with respect to the base 14 to prevent any forward tilting of the lock 3, and other on the other hand, the transverse rib 17, as a function of its positioning along the lateral surface 15, can abut against the profile 7a of the housing 7 in the event of tilting backwards or upwards of said latch 3.
La nervure longitudinale 16, la nervure transversale 17 et l'ergot externe 27 constituent ainsi les moyens de fixation du verrou 3, tandis que la rainure 13 et l'ouverture transversale 10 de la cloison de liaison 9 constituent les moyens de liaison de l'embase 2.The longitudinal rib 16, the transverse rib 17 and the external lug 27 thus constitute the fastening means of the lock 3, while the groove 13 and the transverse opening 10 of the connecting partition 9 constitute the connecting means of the base 2.
Le personnel peut enfin procéder à la fermeture de l'élément ouvrant 28. Celle-ci vient alors de façon classique percuter le nez 22 de la languette 21. Cette dernière est alors entraînée en rotation dans le trigonométrique, et s'efface sous l'action de l'élément ouvrant 28 en offrant une résistance minimale. Une fois l'élément ouvrant 28 dans sa position pseudofermée, la languette 21 et le pont 23 sont libérés de toute contrainte et peuvent donc recouvrer leur forme originelle, comme représenté à la figure 7. L'élément ouvrant 28 est alors en butée contre la cloison 9, comme représenté plus particulièrement à la figure 7.Finally, the personnel can close the opening element 28. The latter then conventionally hits the nose 22 of the tongue 21. The latter is then rotated in the trigonometric, and disappears under the action of the opening member 28 by providing minimal resistance. Once the opening member 28 in its pseudofermed position, the tongue 21 and the bridge 23 are released from any stress and can recover their original shape, as shown in Figure 7. The opening member 28 is then abutted against the partition 9, as shown more particularly in FIG. 7.
Une fois les opérations d'application de peinture achevées, il est alors possible d'extraire l'élément ouvrant 28 des moyens de blocage en forçant la languette 21 à s'effacer. Il suffit ensuite de faire pivoter le verrou 3 de 90° dans le sens des aiguilles d'une montre puis de le translater vers le haut pour extraire le verrou 3 de l'embase 2, et enfin de dissocier l'embase 2 de l'élément fixe 5.Once the paint application operations are completed, it is then possible to extract the opening member 28 of the locking means by forcing the tongue 21 to fade. Then simply rotate the lock 3 90 ° clockwise and translate it upwards. to extract the lock 3 of the base 2, and finally to separate the base 2 of the fixed element 5.
Il est alors possible de procéder à une étape de lavage de l'embase 2 et du verrou 3, puis de les réutiliser, aussi bien avec des véhicules légers qu'avec des véhicules lourds.It is then possible to proceed to a washing step of the base 2 and the lock 3, then reuse them, with both light vehicles and heavy vehicles.
Bien que l'invention ait été décrite en liaison avec des exemples particuliers de réalisation, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention. Although the invention has been described in connection with particular embodiments, it is obvious that it is not limited thereto and that it comprises all the technical equivalents of the means described and their combinations if they are within the scope of the invention.
