Selon la representation donnee sur les figures 2 et 3, il s'agit d'un bouton en forme generale de chapeau evase, adapte pour une ergonomic de manipulation aisee. Cette realisation particuliere n'est This covering 250 can be the subject of numerous embodiments. According to the representation given in Figures 2 and 3, it is a button in the general shape of a flared hat, suitable for ergonomic easy handling. This particular achievement is not

La structure de verrouillage 210 comprend au moins un element The locking structure 210 comprises at least one element
de verrouillage en sail lie 220, comme precedem ment evoq ue. of locking in sail lie 220, as previously mentioned.
Plus precisement encore, selon le mode de realisation preferential illustre sur la figure 2, la structure de verrouillage 210 comprend un fut 212 presentant des proprietes elastiques propres a Even more precisely, according to the preferred embodiment illustrated in FIG. 2, the locking structure 210 comprises a barrel 212 having elastic properties specific to
permettre une deformation et muni de moyens de verrouillage 220. allow deformation and provided with locking means 220.
Selon un mode de realisation particulier, il s'agit d'un fut 212 cylindrique de revolution scinde en plusieurs segments par des fentes longitudinales 214. Selon le mode de realisation particulier donne sur la figure 2, la structure 210 comprend ainsi un fGt 212 scinde en quatre segments circulaires 216. L'un au moins de ces segments 216, et de preference chacun de ceux-ci, comporte un moyen de verrouillage, par exemple une denture interne, au voisinage de son extremite libre, formant l'eiement de verrouillage en saillie 220 precise. Plus precisement encore, chaque denture 220 est delimitee de preference sur son extremite opposee a ltextremite libre des segments 216 par une surface d'arret perpendiculaire a l'axe du fut 212. Par ailleurs, chaque denture 220 est delimitee, dans la direction de l'extremite libre des segments 216 par deux facettes planes formant un diedre convexe effile en direction de l'extremite libre des segments 216 pour former ainsi des rampes facilitant le franchissement des moyens de verrouillage complementaires prevus sur ltorgane 100, par deformation elastique provisoire vers l'exterieur des segments 216 au niveau de ieur According to a particular embodiment, it is a cylindrical barrel 212 of revolution split into several segments by longitudinal slots 214. According to the particular embodiment given in FIG. 2, the structure 210 thus comprises a fGt 212 split into four circular segments 216. At least one of these segments 216, and preferably each of these, comprises a locking means, for example an internal toothing, in the vicinity of its free end, forming the locking element surface 220 precise. Even more precisely, each toothing 220 is preferably delimited on its end opposite the free end of the segments 216 by a stop surface perpendicular to the axis of the barrel 212. Furthermore, each toothing 220 is delimited, in the direction of the free end of the segments 216 by two flat facets forming a convex tapered mortar in the direction of the free end of the segments 216 so as to form ramps facilitating the crossing of the additional locking means provided on the member 100, by provisional elastic deformation towards the outside of segments 216 at ieur level

L'organe de verrouillage 100 represente sur la figure 1 comprend, comme evoque precedemment, d'une part au moins un muret de verrouillage 140 et d'autre part au moins une rampe de liberation 150 orientes selon des directions orthogonales de sorte que le verrouillage de l'organe 200 sur l'organe 100 soit assure lors d'une translation relative entre les deux organes par franchissement du muret de verrouillage 140 par les elements de verrouillage 220 et que la liberation ou deverrouillage soit assure lors d'une rotation relative entre les deux organes 100/200 par deplacement des elements de verrouillage The locking member 100 shown in FIG. 1 comprises, as mentioned above, on the one hand at least one locking wall 140 and on the other hand at least one release ramp 150 oriented in orthogonal directions so that the locking of the member 200 on the member 100 is ensured during a relative translation between the two members by crossing the locking wall 140 by the locking elements 220 and that the release or unlocking is ensured during a relative rotation between the two organs 100/200 by displacement of the locking elements
220 sur la rampe de liberation 150.220 on the release ramp 150.
Plus precisement encore, l'organe de verrouillage comprend de preference un fat cylindrique etage 132. Comme illustre sur la figure 1, ce fut 132 comprend de preference une base 1320 de grande section, prolongee vers son extremite libre par un tronson 1322 de section plus faible. Ce tronson 1322 se prolonge lui-meme par un plateau circulaire 142 de section droite superieure au tronSon 1322. Le plateau 142 possede de preference un diametre identique a la base 1320. Il tient lieu de muret de verrouillage 140. La surface axialement externe du plateau 142, qui deli mite l'extremite libre d u fGt 1 32 est formee de preference Even more precisely, the locking member preferably comprises a cylindrical fat stage 132. As illustrated in FIG. 1, this was 132 preferably comprises a base 1320 of large section, extended towards its free end by a section 1322 of more section low. This tronson 1322 is itself extended by a circular plate 142 of cross section greater than the section 1322. The plate 142 preferably has a diameter identical to the base 1320. It acts as a locking wall 140. The axially external surface of the plate 142, which delimits the free end of the fGt 1 32 is preferably formed
d' une surface ayant pour l'essentiel la forme d' un cone convexe 144. of a surface essentially having the shape of a convex cone 144.
L'homme de l'art comprendra que ce cOne convexe 144 forme une rampe facilitant le franchissement du muret 140 par les dentures 220 iors du verrouillage. Par ailleurs, il est prevu autant de rampes de deverrouillage 150 que de dentures de verrouillage 220. Ainsi, dans le cas particulier et non limitatif represente sur la figure 1, il est prevu quatre rampes de Those skilled in the art will understand that this convex cone 144 forms a ramp facilitating the crossing of the wall 140 by the teeth 220 when locked. Furthermore, as many unlocking ramps 150 are provided as there are locking teeth 220. Thus, in the particular and nonlimiting case represented in FIG. 1, four ramps are provided.
deverrouillage 150.unlocking 150.
Cheque rampe de deverrouillage 150 est formee d'une nervure longitudinale, c'est-a-dire s'etendant parallelement a l'axe du fut 132 sur l'exterieur du tronSon 1322. Les rampes de deverrouillage 150 vent Each release ramp 150 is formed by a longitudinal rib, that is to say extending parallel to the axis of the barrel 132 on the outside of the section 1322. The release ramps 150 wind
equi-reparties autour de cet axe.equi-distributed around this axis.
Chaque rampe de deverrouillage 150 possede une section droite en forme de triangle symetrique par rapport a un plan passant par l'axe du fut 132. Ainsi, chaque rampe 150 est delimitee par deux facettes 152, 154 definissant en combinaison un diedre convexe. Cependant, le sommet de chaque nervure 150 est tronque par une gorge longitudinale 156. Celle-ci se prolonge jusque sur l'extremite libre du fat 132. Ainsi, chaque gorge 156 s'etend au moins sur toute l'epaisseur du plateau 142 Each unlocking ramp 150 has a cross section in the form of a triangle symmetrical with respect to a plane passing through the axis of the barrel 132. Thus, each ramp 150 is delimited by two facets 152, 154 defining in combination a convex mortar. However, the top of each rib 150 is truncated by a longitudinal groove 156. This extends as far as the free end of the fat 132. Thus, each groove 156 extends at least over the entire thickness of the plate 142
formant les murets 140.forming the walls 140.
En variante on peut prevoir une telle gorge 156 sur certaines seulement des nervures 150, voire une seule de celles-ci. Dans ce cas, lorsque une denture 220 repose dans la gorge 156 en question, les autres dentures 220 vent positionnees sur le sommet des autres As a variant, it is possible to provide such a groove 156 on only some of the ribs 150, or even only one of these. In this case, when a toothing 220 rests in the groove 156 in question, the other toothing 220 is positioned on the top of the other
nervures 150.ribs 150.
Enfin, on notera que de preference la surface d'extremite 144 en forme de tronc de cOne possede en regard de chaque gorge 156 une nervure 146 concue pour eviter que lors de ['assemblage une denture 220 ne soit engagee dans la gorge 156. Chaque nervore 146 est delimitee par deux facettes planes formant un diedre convexe symetrique par rapport a un plan axial passant par l'axe longitudinal du Finally, it will be noted that preferably the end surface 144 in the form of a trunk of cone has, opposite each groove 156, a rib 146 designed to avoid that during assembly the teeth 220 are not engaged in the groove 156. Each nervore 146 is delimited by two plane facets forming a convex diere symmetrical with respect to an axial plane passing through the longitudinal axis of the
fut 132 et l'axe de la gorge 156.was 132 and the axis of the gorge 156.
Pour assembler l'organe 200 sur l'organe 100, on procede To assemble the member 200 on the member 100, we proceed
essentiellement comme suit.basically as follows.
L'organe 200 est presente en regard de l'organe 100 coaxialement a celuici. Les dentures 220 viennent reposer sur la surface 144. Les diedres 146 interdisent aux dentures 220 de penetrer The member 200 is present opposite the member 100 coaxially therewith. The teeth 220 come to rest on the surface 144. The diedres 146 prevent the teeth 220 from penetrating
dans les gorges 156.in the gorges 156.
Il suffit done par translation relative de solliciter ['element 200 en rapprochement de la base du fut 132. Par deformation elastique des languettes 216 les dentures 220 franchissent le plateau 142 formant muret. Le verrouillage est obtenu des lors que les dentures 220 ont franchi ce plateau. L'organe 200 est alors prisonnier sur l'organe 100, cheque denture 220 etant dispose dans un logement delimite axialement respectivement par le plateau 142 et la base 1320 du fut 132 et delimite It therefore suffices by relative translation to urge the element 200 closer to the base of the barrel 132. By elastic deformation of the tongues 216 the teeth 220 cross the plate 142 forming a low wall. Locking is obtained as soon as the teeth 220 have crossed this plateau. The member 200 is then trapped on the member 100, check teeth 220 being placed in a housing delimited axially respectively by the plate 142 and the base 1320 of the barrel 132 and delimited
radialement par les nervures 150.radially by the ribs 150.
Pour assurer le deverrouillage de l'organe 200, il suffit de forcer l'organe 200 a rotation (sur un quart de tour pour un dispositif a quatre dentures 220 equi-reparties) pour assurer le franchissement des facettes 152, 154 par les dentures 220 grace a la deformation eiastique des languettes 216. Les dentures 220 atteignent ainsi les gorges 156. Et To ensure the unlocking of the member 200, it suffices to force the member 200 to rotate (over a quarter turn for a device with four teeth 220 equi-distributed) to ensure the crossing of the facets 152, 154 by the teeth 220 thanks to the elastic deformation of the tongues 216. The teeth 220 thus reach the grooves 156. And
il suffit de retirer par translation l'organe 200. it suffices to remove by translation the member 200.
Le dispositif de fixation forme par les organes 100 et 200 The fixing device forms by the members 100 and 200
precites peut faire ['objet de nombreuses configurations d'utilisation. above can be subject to many configurations of use.
De preference, ce dispositif est utilise pour immobiliser un accessoire entre l'habillage 250 de l'organe 200 et un evasement 184 solidaire de l'organe 100. Un tel accessoire peut etre forme par exemple d'un cache de moteur de vehicule automobile comme evoque Preferably, this device is used to immobilize an accessory between the covering 250 of the member 200 and a flaring 184 secured to the member 100. Such an accessory can be formed for example from a motor vehicle engine cover such as evoked

On apersoit ainsi sur la figure 3, un etrier 182 comprenant deux branches principales 1820, 1822, paralleles entre elles et paralleles a l'axe longitudinal general O-O de ['element de base 110 de la piece de liaison 160 et de ['element de fixation/reception 130, venues de matiere sur ['element de base 110. Cheque branche 1820, 1822, comporte a son extremite libre opposee a ['element de base 110 un doigt 1821, 1823, dirige radialement vers l'interieur, soit vers l'axe longitudinal du dispositif, en regard d u retrecissement 1 64. L' hom me de l'a rt comprendra que l'etrier 182 permet de limiter le deplacement de I'element de fixation/reception 130 dans toute direction orthogonale a There is thus seen in FIG. 3, a stirrup 182 comprising two main branches 1820, 1822, mutually parallel and parallel to the general longitudinal axis OO of the basic element 110 of the connecting piece 160 and of the fixation / reception 130, coming from matter on the basic element 110. Check branch 1820, 1822, has at its free end opposite to the basic element 110 a finger 1821, 1823, directed radially towards the interior, ie towards the longitudinal axis of the device, opposite the narrowing 1 64. The man of the rt will understand that the stirrup 182 makes it possible to limit the displacement of the fixing / reception element 130 in any direction orthogonal to
l'axe longitudinal O-O de la piece.the longitudinal axis O-O of the part.
Le cas echeant, les moyens de limitation 180 peuvent etre completes par un plateau 184 solidaire de la piece de liaison 160, propre a venir en appui contre le sommet de l'etrier 182 en cas de deplacement de ['element de fixation/reception 130 superieur a un seuil dans une direction orthogonale a l'axe longitudinal O-O et parallele au canal libre If necessary, the limiting means 180 can be completed by a plate 184 secured to the connecting piece 160, suitable for coming into abutment against the top of the stirrup 182 in the event of displacement of the fixing / receiving element 130 greater than a threshold in a direction orthogonal to the longitudinal axis OO and parallel to the free channel
entre les deux doigts 1821, 1823.between the two fingers 1821, 1823.
Comme on le volt sur la figure 3, des nervores de raidissement 186, peuvent etre prevues sur les francs internee des branches 1820, As shown in FIG. 3, stiffening ribs 186 can be provided on the internal francs of the branches 1820,
1822, au voisinage de ['element de base 110. 1822, in the vicinity of the basic element 110.
Bien entendu la presente invention n'est pas limitee au mode de realisation particulier qui vient d'etre decrit mais s'etend a toute Of course, the present invention is not limited to the particular embodiment which has just been described but extends to any
variante conforme a son esprit.variant according to his spirit.
En particulier les modalites de realisation des retrecissements dans la piece intermediaire 160 ne vent pas limitees aux modes de In particular, the modalities of carrying out the narrowing in the intermediate piece 160 are not limited to the modes of
realisation particuliers precedemment decrits. particular realization previously described.
On a illustre sur la figure 4 une variante de realisation selon laquelle les deux retrecissements separes 162, 164 possedent des orientations differentes decalees de 90 . Plus precisement selon ce mode de realisation, cheque retrecissement 162, 164 est forme de deux gorges rectilignes, paralleles entre elles, debouchant sur des faces opposees de la piece intermediaire 160. Ces gorges vent referencees 1625 et 1626 pour le retrecissement 162, et 1645 et 1646 pour le retrecissement 164. On notera que les gorges 1625 et 1626 vent orthogonales aux gorges 1645 et 1646. Selon le mode de realisation illustre sur la figure 4, les gorges 1625, 1626, 1645 et 1646 ont des sections droites triangulaires. Cependant ['invention n'est pas iimitee a ce mode de realisation particulier. Les gorges 1625, 1626, 1645 et 1646 peuvent presenter toute autre geometric appropriee. Chacun des deux retrecissements 16Z, 164 permet une inclinaison relative entre les elements 110 et 130 correspondent a un mouvement de rotation autour d'un axe parallele a la direction d'elongation des gorges 1625, 1626, 1645 et 1646. On a illustre sur la figure 5 une autre variante selon laquelle la piece intermediaire 160 possede deux parallelogrammes deformables 162, 164 decales de 90 I'un par rapport a l'autre. En l'espece chacun des deux parallelogrammes est forme d'une cage comprenant deux montants 1627, 1628, 1647, 1648, paralleles entre eux et munis chacun de deux zones de retrecissements formes par exemple, mais non iimitativement, par 4 gorges 1629, 1649, associees deux a deux. Les montants 1627, 1628 du parallelogramme 162 vent orientes perpendiculairement aux montants 1647 et 1648 du parallelogramme 164. De meme les gorges 1629 du parallelogramme 162 vent orientees perpendiculairement aux gorges 1649 du parallelogramme 164. La encore la geometric des gorges, notamment leur section, peut faire ['objet de nombreuses variantes. Chacun des deux parallelogrammes 162, 164 permet un deplacement relatif entre les elements 110 et 130 correspondent a un mouvement de translation selon une direction (referencee respectivement D1 et D2 sur la figure 5) orthogonale a la direction d'elongation des gorges 1629, 1649 respectivement. Ainsi les parallelogrammes 162, 164 illustres sur la figure 5 permettent de FIG. 4 illustrates an alternative embodiment according to which the two separate constrictions 162, 164 have different orientations offset by 90. More precisely, according to this embodiment, each shrinkage 162, 164 is formed by two rectilinear grooves, parallel to each other, opening onto opposite faces of the intermediate piece 160. These grooves are referenced 1625 and 1626 for the shrinkage 162, and 1645 and 1646 for the narrowing 164. It will be noted that the grooves 1625 and 1626 are orthogonal to the grooves 1645 and 1646. According to the embodiment illustrated in FIG. 4, the grooves 1625, 1626, 1645 and 1646 have straight triangular sections. However, the invention is not limited to this particular embodiment. The grooves 1625, 1626, 1645 and 1646 can have any other suitable geometric. Each of the two narrowing 16Z, 164 allows a relative inclination between the elements 110 and 130 correspond to a rotational movement around an axis parallel to the direction of elongation of the grooves 1625, 1626, 1645 and 1646. We have illustrated on the FIG. 5 another variant according to which the intermediate piece 160 has two deformable parallelograms 162, 164 shifts of 90 relative to one another. In this case, each of the two parallelograms is formed from a cage comprising two uprights 1627, 1628, 1647, 1648, parallel to each other and each provided with two narrowing zones formed for example, but not limited, by 4 grooves 1629, 1649 , paired two by two. The amounts 1627, 1628 of the parallelogram 162 wind oriented perpendicular to the amounts 1647 and 1648 of the parallelogram 164. Similarly the grooves 1629 of the parallelogram 162 wind oriented perpendicular to the grooves 1649 of the parallelogram 164. Again the geometric of the grooves, in particular their section, can be the subject of many variations. Each of the two parallelograms 162, 164 allows relative displacement between the elements 110 and 130 correspond to a translational movement in a direction (respectively referenced D1 and D2 in FIG. 5) orthogonal to the direction of elongation of the grooves 1629, 1649 respectively . Thus the parallelograms 162, 164 illustrated in FIG. 5 make it possible to
maintenir un parallelisme entre les elements 110 et 130. maintain a parallelism between the elements 110 and 130.
Bien evidemment en variante, on peut prevoir un parallelogramme unique dans la piece intermediaire 160, entre les Obviously in a variant, it is possible to provide a single parallelogram in the intermediate piece 160, between the
elements 110 et 130.elements 110 and 130.
