Description
Dispositif de jonction. l'une à l'autre. des deux extrémités d'une armature métallique plate.Joining device. to each other. from both ends of a flat metal frame.
La présente invention concerne un dispositif de jonction, l'une à l'autre, des deux extrémités d'une armature métallique plate à section rectangulaire ou sensiblement rectangulaire. The present invention relates to a device for joining, to one another, the two ends of a flat metal frame with rectangular or substantially rectangular section.
Il pourra s'agir par exemple d'une armature de joint de carter ou analogue, sur laquelle est surmoulé un bourrelet d'étanchéité en élastomère ou analogue. Le dispositif de jonction objet de l'invention peut donc avoir pour rôle de relier l'une à l'autre les deux extrémités aboutées d'une telle armature, pour constituer une ceinture fermée. It may for example be a casing gasket frame or the like, on which is molded a sealing bead of elastomer or the like. The joining device which is the subject of the invention can therefore have the role of connecting the two abutting ends of such a frame to one another, to form a closed belt.
En effet, il est avantageux de constituer de telles armatures en plusieurs tronçons, par exemple en forme d'équerres, pour éviter les pertes de métal lors de la découpe, ces tronçons pouvant s'imbriquer de sorte à éviter les pertes de matière qui autrement seraient inévitables, au centre d'une structure fermée. Indeed, it is advantageous to constitute such reinforcements in several sections, for example in the form of brackets, to avoid losses of metal during cutting, these sections being able to overlap so as to avoid losses of material which otherwise would be inevitable, in the center of a closed structure.
Une telle liaison doit être relativement résistante vis-à-vis des efforts s'exerçant dans les deux directions perpendiculaires à la direction d'assemblage. En outre, l'assemblage ne doit pas présenter de surépaisseur par rapport à l'épaisseur que présente l'armature en dehors de la zone de jonction, car une telle surépaisseur au niveau de la jonction nuirait évidemment à l'étanchéité du joint. Such a connection must be relatively resistant to the forces exerted in the two directions perpendicular to the direction of assembly. In addition, the assembly must not have any excess thickness compared to the thickness that the reinforcement has outside the junction zone, since such an excess thickness at the junction would obviously harm the sealing of the joint.
Dans un dispositif de jonction connu, les deux extrémités en aboutement de l'armature sont solidarisées par adhérisation, sur leur tranche, d'une couche intercalaire de la matière du bourrelet, mais ceci entraîne la nécessité d'augmenter la largeur de l'armature au niveau de la jonction, pour donner à cette couche intercalaire une forme sinueuse, de sorte à ce qu'elle ait une longueur augmentée, et que les extrémités en aboutement s'emboîtent l'une dans l'autre. In a known joining device, the two abutting ends of the frame are joined by adhering, on their edge, an intermediate layer of the bead material, but this leads to the need to increase the width of the frame at the junction, to give this intermediate layer a sinuous shape, so that it has an increased length, and the abutting ends fit into each other.
Cependant l'adhérisation de l'élastomère sur la tranche des extrémités de l'armature est problématique, et cet excès de largeur de l'armature constitue aussi un inconvénient, car il entraîne corrélativement un renflement des pièces adjacentes entre lesquelles le joint est interposé. However, the adhesion of the elastomer on the edge of the ends of the frame is problematic, and this excess width of the frame also constitutes a drawback, because it correlatively causes a swelling of the adjacent parts between which the seal is interposed.
Le but de l'invention est d'éliminer ce type d'inconvénient tout en répondant aux autres conditions susdéfinies. The object of the invention is to eliminate this type of drawback while meeting the other conditions defined above.
A cet effet, un dispositif de jonction conforme à l'invention, du type général défini au début, est caractérisé en ce que chaque extrémité d'armature est divisée longitudinalement, sur une longueur dite "de jonction", en deux languettes d'épaisseur plus faible que celle de la partie restante de l'armature, ces deux languettes étant décalées l'une par rapport à l'autre dans une direction perpendiculaire au plan de ladite armature, mais en se situant à l'intérieur du contour de la section de ladite partie restante de l'armature, de sorte que les deux dites extrémités puissent s'imbriquer l'une dans l'autre en têtebêche, sensiblement selon ladite longueur de jonction. To this end, a junction device according to the invention, of the general type defined at the start, is characterized in that each end of the reinforcement is divided longitudinally, over a length known as "junction", into two thickness tabs weaker than that of the remaining part of the frame, these two tabs being offset with respect to each other in a direction perpendicular to the plane of said frame, but being located inside the contour of the section of said remaining part of the armature, so that the two said ends can be nested one inside the other at head to tail, substantially along said junction length.
Chaque languette d'une extrémité de l'armature peut être assujettie à plat sur la languette correspondante de l'autre extrémité par tout moyen adéquat, par exemple par collage, soudage par points, ou même par un simple enrobage dans l'élastomère ou le caoutchouc constituant le bourrelet d'étanchéité. On pourrait aussi prévoir sur les languettes des déformations localisées en forme de crans, permettant leur encliquetage mutuel. Each tab on one end of the frame can be fixed flat on the corresponding tab on the other end by any suitable means, for example by gluing, spot welding, or even by a simple coating in the elastomer or the rubber constituting the sealing bead. One could also provide localized deformations on the tongues in the form of notches, allowing their mutual snap-fastening.
Un mode d'exécution de l'invention va maintenant être décrit à titre d'exemple nullement limitatif, avec référence aux figures du dessin annexé dans lequel
- la figure 1 montre en perspective les deux extrémités d'une armature de joint, conformées selon l'invention, avant assemblage
- la figure 2 est une vue de profil d'une de ces extrémités ; et
- la figure 3 montre partiellement en plan une armature de joint conforme à l'invention après assemblage des deux extrémités.An embodiment of the invention will now be described by way of non-limiting example, with reference to the figures of the accompanying drawing in which
- Figure 1 shows in perspective the two ends of a joint frame, shaped according to the invention, before assembly
- Figure 2 is a side view of one of these ends; and
- Figure 3 shows partially in plan a joint reinforcement according to the invention after assembly of the two ends.
Sur la figure 1, les extrémités de tronçons d'armature, supposée métallique et à section rectangulaire, ont été référencées en 1 et 1', et les languettes précitées en 2 et 2'. L'épaisseur de l'armature étant e, celle des languettes sera légèrement inférieure à e/2. Leur amincissement peut être obtenu par aplatissement à la presse, ou par enlèvement de métal. L'élargissement 3 des languettes 2,2' consécutif à leur aplatissement peut être supprimé par enlèvement de métal, si l'on veut éviter tout accroissement de la largeur de l'armature 1, 1' au niveau de la jonction. In FIG. 1, the ends of reinforcement sections, assumed to be metallic and of rectangular section, have been referenced in 1 and 1 ′, and the aforementioned tongues in 2 and 2 ′. The thickness of the frame being e, that of the tabs will be slightly less than e / 2. Thinning can be obtained by flattening with the press, or by removing metal. The widening 3 of the tongues 2,2 ′ consecutive to their flattening can be eliminated by removing metal, if one wishes to avoid any increase in the width of the frame 1, 1 ′ at the junction.
La fente 4 séparant les deux languettes 2 et 2' peut être obtenue par cisaillement lors de l'estampage à la presse, en une seule opération.The slot 4 separating the two tongues 2 and 2 'can be obtained by shearing during stamping with the press, in a single operation.
On voit sur le dessin que l'aplatissement de la languette 2 est tel que sa face 2a est de niveau avec la face la de l'armature 1, 1' tandis que son autre face 2b est décalée par rapport au niveau de l'autre face lb de l'armature, qui était son niveau avant aplatissement. Pour la languette 2', c'est l'inverse : sa face 2'b est de niveau avec la face lb de l'armature, tandis que sa face 2'a est décalée par rapport au niveau de la face la de l'armature, qui était son niveau avant aplatissement. On voit aussi que ce décalage des deux languettes n'empêche pas qu'elles restent toutes deux à l'intérieur du contour de la partie non déformée de l'armature 1, 1', ce qui évitera toute surépaisseur après assemblage en tête-bêche avec une autre extrémité d'armature, conformée de la même manière. We see in the drawing that the flattening of the tongue 2 is such that its face 2a is level with the face 1a of the frame 1, 1 'while its other face 2b is offset from the level of the other side lb of the armature, which was its level before flattening. For the tongue 2 ', it is the opposite: its face 2'b is level with the face lb of the frame, while its face 2'a is offset from the level of the face la of the frame, which was its level before flattening. We also see that this offset of the two tabs does not prevent that they both remain inside the contour of the non-deformed part of the frame 1, 1 ′, which will avoid any excess thickness after assembly head to tail with another end of frame, shaped in the same way.
Après assemblage, la solidarisation de ces deux extrémités l'une sur l'autre pourra être assurée par l'un des moyens indiqués plus haut. Sur la figure 3, on a supposé un assujettissement réalisé par collage de chaque languette sur la languette coopérante de l'autre extrémité. Cette fixation peut être remplacée ou complétée par enrobage de ces extrémités d'armature dans la matière constituant le bourrelet d'étanchéité 5. After assembly, the joining of these two ends to each other can be ensured by one of the means indicated above. In FIG. 3, it has been assumed that it is secured by bonding each tongue to the cooperating tongue at the other end. This fixing can be replaced or supplemented by coating these reinforcing ends in the material constituting the sealing bead 5.
