Description
"Ensemble articulé et notamment arrêt de porte pour véhicule automobile!?. "Articulated assembly and in particular door stop for motor vehicle!?.
Cet ensemble articulé comporte deux éléments pivotant l'un par rapport à l'autre sur un axe réalisé sous la forme d'un rivet par l'intermédiaire d'une bague en acier à ressort, cylindrique à section non circulaire, venant localement en contact de l'axe et des éléments pivotants en des points décalés angulairement. This articulated assembly comprises two elements pivoting with respect to each other on an axis produced in the form of a rivet by means of a spring steel ring, cylindrical with non-circular section, coming locally into contact of the axis and of the pivoting elements at points angularly offset.
Cet ensemble est caractérisé en ce que l'un des éléments est constitué par une chape dont les deux branches sont pourvues de perçages recevant l'axe d'articulation et en ce que la bague traverse le perçage de l'une des branches pour venir s'appliquer par l'une de ses extrémités contre la tête rivetée de l'axe tandis que l'autre extrémité de cette bague vient s'appliquer contre la face latérale de l'autre branche. This assembly is characterized in that one of the elements consists of a yoke, the two branches of which are provided with holes receiving the hinge pin and in that the ring passes through the bore of one of the branches to come s 'Apply by one of its ends against the riveted head of the axis while the other end of this ring is applied against the side face of the other branch.
L'invention est représentée à titre d'exemple non limitatif sur les dessins ci-joints dans lesquels
- la figure 1 est une vue partielle, partiellement coupée, de l'ensemble articulé conforme à l'invention,
- la figure 2 est une vue agrandie de la figure 1,
- la figure 3 est une coupe suivant A-A de la figure 2 montrant l'articulation à hauteur de 1' axe. The invention is shown by way of non-limiting example in the accompanying drawings in which
FIG. 1 is a partial view, partially cut away, of the articulated assembly according to the invention,
FIG. 2 is an enlarged view of FIG. 1,
- Figure 3 is a section along AA of Figure 2 showing the joint at the height of one axis.
La présente invention a pour but la réalisation d'un ensemble articulé de fabrication simple, de construction robuste, qui notamment dans le cas d'un arrêt de porte pour véhicule automobile, permet de supprimer les jeux et d'amortir les chocs résultant de l'action des cames du frein de porte en position de demi-ouverture ou d'ouverture de cette porte. The object of the present invention is to produce an articulated assembly of simple manufacture, of robust construction, which in particular in the case of a door stop for a motor vehicle, makes it possible to eliminate the clearances and to absorb the shocks resulting from the action of the door brake cams in the half-open or open position of this door.
L'invention a également pour but la réalisation d'un arrêt de porte pour véhicule automobile, qui résiste efficacement, sans subir de déformation permanente, aux forces de traction et de compression auxquelles il est soumis, en réduisant les phénomènes d'usure et en supprimant les bruits importants et désagréables se produisant lors de l'ouverture ou de la fermeture des portes de voitures. Another object of the invention is to produce a door stop for a motor vehicle, which effectively withstands, without undergoing permanent deformation, the tensile and compressive forces to which it is subjected, reducing the phenomena of wear and suppressing significant and unpleasant noises occurring when opening or closing car doors.
L'invention autorise également le rattrapage des différences de hauteur de fixation des deux éléments de l'ensemble articulé, l'un sur l'encadrement de porte, l'autre sur la porte, sans nuire en quoi que ce soit au fonctionnement correct de l'ensemble articulé. The invention also allows the differences in fixing height of the two elements of the articulated assembly to be made up, one on the door frame, the other on the door, without in any way detracting from the correct functioning of the articulated assembly.
Les deux éléments de cet ensemble articulé se composent d'une chape 1 entre les deux branches parallèles 2, 3 de laquelle est monté pivotant un bras 6 en forme de lame. La chape 1 et la lame 6 sont réalisées en acier et l'écartement des branches 2 et 3 est tel que la lame 6 se loge avec un jeu important entre ces branches. The two elements of this articulated assembly consist of a yoke 1 between the two parallel branches 2, 3 of which is pivotally mounted an arm 6 in the form of a blade. The yoke 1 and the blade 6 are made of steel and the spacing of the branches 2 and 3 is such that the blade 6 is housed with a large clearance between these branches.
La lame 6 comporte, à son extrémité libre, comme cela est connu, des surfaces de cames coopérant avec des galets montés sur le battant de porte afin de déterminer les positions de demi-ouverture et d'ouverture de la porte. The blade 6 has, at its free end, as is known, cam surfaces cooperating with rollers mounted on the door leaf in order to determine the half-opening and opening positions of the door.
La chape 1 est destinée à se fixer sur l'encadrement d'une porte par l'intermédiaire de vis ou similaires passées au travers d'orifices 11. Les deux branches parallèles 2 et 3 de la chape sont pourvues de perçages 21 et 31 recevant l'axe d'articulation de la lame 6 constitué par un rivet 4. The yoke 1 is intended to be fixed on the frame of a door by means of screws or the like passed through orifices 11. The two parallel branches 2 and 3 of the yoke are provided with holes 21 and 31 receiving the hinge axis of the blade 6 constituted by a rivet 4.
Les deux perçages 2 et 31 des branches 2 et 3 sont de diamètre différent, le perçage 21 de diamètre plus faible étant réalisé de manière que la base du rivet 4 adjacente de la tête 41 vienne s'emmancher sans jeu et de préférence à force dans cet orifice 21. The two holes 2 and 31 of the branches 2 and 3 are of different diameters, the hole 21 of smaller diameter being produced so that the base of the rivet 4 adjacent to the head 41 comes to be fitted without play and preferably by force in this orifice 21.
Autour du rivet 4 est disposée une bague en acier à ressort 5 fendue en 51 suivant l'une de ses génératrices. Cette bague est d'une longueur correspondant sensiblement à la distance séparant la face latérale interne 22 de la branche 2 de la chape à la face latérale externe 32 de l'autre branche 3. Around the rivet 4 is disposed a spring steel ring 5 split at 51 along one of its generatrices. This ring is of a length corresponding substantially to the distance separating the internal lateral face 22 of the branch 2 of the yoke from the external lateral face 32 of the other branch 3.
Cette bague cylindrique est à section non circulaire de manière que la courbure de ses parois varie progressivement entre des zones à grand rayon de courbure 52 et des zones à petit rayon de courbure 53. This cylindrical ring is of non-circular cross section so that the curvature of its walls varies progressively between zones with a large radius of curvature 52 and zones with a small radius of curvature 53.
Ainsi, cette bague qui est logée dans les perçages cylindriques à section circulaire de même diamètre 31 de la branche 3 et 61 de la lame 6, est réalisée de manière telle qu'elle vient localement en contact de la paroi de ces perçages 31 et 61 en des zones, respectivement 71 et 72, qui sont décalées angulairement l'une de l'autre. Thus, this ring which is housed in the cylindrical holes of circular section of the same diameter 31 of the branch 3 and 61 of the blade 6, is produced in such a way that it comes locally into contact with the wall of these holes 31 and 61 into zones, respectively 71 and 72, which are angularly offset from one another.
De préférence, la construction non circulaire de cette bague 5 est telle qu'elle vient au contact de l'axe du rivet 4 et de la paroi des perçages 31 et 61 en trois zones décalées angulairement, les deux bords de la fente 51 étant établis de façon que l'un vienne en contact de la paroi des perçages 61 et 31 et l'autre en contact de l'axe du rivet 4. Preferably, the non-circular construction of this ring 5 is such that it comes into contact with the axis of the rivet 4 and the wall of the holes 31 and 61 in three zones offset angularly, the two edges of the slot 51 being established so that one comes into contact with the wall of the holes 61 and 31 and the other comes into contact with the axis of the rivet 4.
Du fait de cette construction, on constate que lors du rivetage de l'extrémité 42 du rivet 4, les extrémités de la bague 5 sont appliquées sur des matériaux de nature différente, l'une des extrémités 54 étant appliquée perpendiculairement contre l'acier constituant la chape 1 alors que l'autre extrémité 55 vient directement en contact du métal de nature, de structure et de dureté différentes constituant le rivet 4. Cela permet, lors du rivetage, de favoriser l'expansion de la tige 4 du rivet en 43 localement sous la tête rivetée 42. Cette expansion en 43 se traduit par un ancrage de l'extrémité 55 de la bague dans la matière du rivet de façon que la bague soit, à cette extrémité, maintenue fermement sans pouvoir se déformer par le métal du rivet. Par contre, l'autre extrémité de la bague peut se déformer et se déplacer contre la paroi 22 lorsque la lame 6 subit des chocs de traction et de compression. La bague 6 constitue ainsi un amortisseur extrêmement fiable de ces chocs comme cela est nécessaire lorsque l'ensemble articulé constitue un ensemble d'arrêt de porte pour véhicule automobile et doit donc fonctionner un grand nombre de fois sans que ses caractéristiques soient modifiées. Due to this construction, it can be seen that during the riveting of the end 42 of the rivet 4, the ends of the ring 5 are applied to materials of different nature, one of the ends 54 being applied perpendicularly against the steel constituting the yoke 1 while the other end 55 comes directly into contact with the metal of different nature, structure and hardness constituting the rivet 4. This makes it possible, during riveting, to promote the expansion of the rod 4 of the rivet at 43 locally under the riveted head 42. This expansion at 43 results in an anchoring of the end 55 of the ring in the material of the rivet so that the ring is, at this end, held firmly without being able to deform by the metal of the rivet. On the other hand, the other end of the ring can deform and move against the wall 22 when the blade 6 undergoes traction and compression shocks. The ring 6 thus constitutes an extremely reliable shock absorber of these shocks as is necessary when the articulated assembly constitutes a door stop assembly for a motor vehicle and must therefore operate a large number of times without its characteristics being modified.
Les avantages de l'invention résultent principalement du fait que lors de l'opération de rivetage, les extrémités de la bague 5 sont appliquées sur des matériaux de nature différente se traduisant par le verrouillage de l'extrémité 55 au voisinage de la tête rivetée 42 et au contraire la possibilité de libre déplacement de l'extrémité 54 adjacente de la branche 2. The advantages of the invention result mainly from the fact that during the riveting operation, the ends of the ring 5 are applied to materials of different nature resulting in the locking of the end 55 in the vicinity of the riveted head 42 and on the contrary the possibility of free movement of the adjacent end 54 of branch 2.
