Description
Rivet tubulaire taraudé étanche.Waterproof threaded tubular rivet.
La présente invention se rapporte aux rivets tubulaires taraudés, notamment à ceux qui servent d'écrous noyés qui peuvent se poser quand on n'a accès qu'à un seul côté d'une pièce. The present invention relates to threaded tubular rivets, in particular to those which serve as submerged nuts which can be posed when one has access to only one side of a part.
On connait déjà un rivet tubulaire taraudé, comprenant un fût cylindrique dont la paroi latérale intérieure est taraudée et qui est prolongé par une tête faisant saillie radialement de la paroi latérale extérieure du fût, et une bague d'étanchéité, qui est fixée sous la tête et qui a le même axe que le fût, ce dernier étant destiné à être engagé dans un trou défini par une surface latérale se trouvant à une certaine distance radiale de la paroi latérale extérieure du fût. We already know a tapped tubular rivet, comprising a cylindrical barrel whose inner side wall is tapped and which is extended by a head projecting radially from the outer side wall of the barrel, and a sealing ring, which is fixed under the head and which has the same axis as the barrel, the latter being intended to be engaged in a hole defined by a lateral surface being at a certain radial distance from the external lateral wall of the barrel.
La mise en place et la fixation du rivet s'effectuent en introduisant le fût cylindrique dans le trou ménagé à cet effet dans la pièce destinée à recevoir le rivet, la tête du rivet venant en butée contre l'une des faces de la pièce et le fût tubulaire dépassant au-delà de l'autre face ; un effort de compression axiale est ensuite appliqué au rivet en vue de provoquer une déformation localisée en bourrelet du fût, ce qui entraîne le serrage de la pièce entre la tête et le bourrelet, ainsi qu'un serrage du joint. The establishment and fixing of the rivet is carried out by introducing the cylindrical barrel into the hole provided for this purpose in the part intended to receive the rivet, the head of the rivet abutting against one of the faces of the part and the tubular barrel projecting beyond the other side; an axial compression force is then applied to the rivet in order to cause a localized deformation in a bead of the barrel, which causes the part to be clamped between the head and the bead, as well as a tightening of the joint.
Dans le cas d'un fût cylindrique, à section droite circulaire, engagé dans un trou de même section droite, il peut arriver que le rivet tourne autour de son axe. Pour y remédier on a proposé de donner au trou une section droite polygonale. Mais alors il y a un intervalle important entre la paroi latérale extérieure du fût et certaines parties de la surface latérale de la pièce délimitant le trou. Lors de la formation du bourrelet, la bague d'étanchéité flue dans cet intervalle. Comme elle n'est plus comprimée sur toute sa surface, elle n'assure plus l'étanchéité requise. In the case of a cylindrical barrel, with a circular straight section, engaged in a hole of the same straight section, it may happen that the rivet turns around its axis. To remedy this, it has been proposed to give the hole a polygonal cross section. But then there is a significant gap between the external lateral wall of the barrel and certain parts of the lateral surface of the part delimiting the hole. During the formation of the bead, the sealing ring flows in this interval. As it is no longer compressed over its entire surface, it no longer provides the required seal.
Pour empêcher la rotation du rivet, on a déjà proposé de donner au fût et au trou des formes cylindriques de section droite polygonale. Comme on ne connaît pas de joints polygonaux, ces rivets ne sont pas étanches. To prevent rotation of the rivet, it has already been proposed to give the barrel and the hole cylindrical shapes of polygonal cross section. As there are no known polygonal joints, these rivets are not waterproof.
En outre, dans les rivets à bague d'étanchéité antérieurs, la bague peut se détacher du rivet pendant le stockage ou le transport. Or, une fois que le rivet a été posé, on ne peut plus savoir visuellement s'il est muni d'une bague d'étanchéité ou non. In addition, in prior seal ring rivets, the ring may detach from the rivet during storage or transportation. However, once the rivet has been laid, one can no longer know visually whether it is fitted with a sealing ring or not.
L'invention pallie ces inconvénients par un rivet tubulaire taraudé qui assure une bonne étanchéité, même quand le trou conjugué n'a pas la même section droite que le fût et laisse subsister notamment de grands intervalles entre eux et même si tant le fût que le trou sont polygonaux. The invention overcomes these drawbacks by a threaded tubular rivet which ensures a good seal, even when the conjugate hole does not have the same cross section as the barrel and leaves in particular large intervals between them and even if both the barrel and the hole are polygonal.
Suivant l'invention, avant la pose, le bord intérieur de la bague d'étanchéité est à distance de la paroi extérieure du fût. According to the invention, before installation, the inner edge of the sealing ring is spaced from the outer wall of the barrel.
Grâce à cet écartement du fût et de la bague d'étanchéité, celle-ci, lors de la pose, ne flue pas dans l'intervalle compris entre le fût et le trou, puisqu'elle dispose de suffisamment de place pour fluer le long de la face inférieure de la tête La bague ne se déforme pas sur le bourrelet avec les deformations et ruptures que cela entraîne et qui sont néfastes à l'étanchéité. Thanks to this spacing of the barrel and the sealing ring, the latter, during installation, does not flow in the interval between the barrel and the hole, since it has enough room to flow along of the underside of the head The ring does not deform on the bead with the deformations and ruptures that this causes and which are harmful to the seal.
De préférence, avant la pose, la distance radiale entre le bord intérieur de la bague d'étanchéi- té et la paroi extérieure du fut n-' est pas inférieure à la distance radiale entre la surface latérale dé fi- nissant le trou et la paroi extérieure du fût. On est ainsi encore plus sur que le fluage ne s'effectuera pas axialement. On peut également loger une partie supérieure de la bague d'étanchéité dans une cavité débouchant sur la face inférieure de la tête. En limitant ainsi le fluage radial vers l'intérieur, on prévient également tout fluage axial le long dufût. Preferably, before installation, the radial distance between the inner edge of the sealing ring and the outer wall of the barrel is not less than the radial distance between the lateral surface defining the hole and the outside wall of the barrel. It is thus even more certain that the creep will not take place axially. One can also accommodate an upper part of the sealing ring in a cavity opening onto the underside of the head. By thus limiting inward radial creep, it also prevents any axial creep along the barrel.
Suivant une variante préférée, il est prévu un anneau ou une patte qui est d'un seul tenant avec la bague d'étanchéité et qui s'étend le long de la paroi latérale extérieure de la tête. Cette patte ou cet anneau permet de constater la présence de la bague d'étanchéité après la pose par un simple examen visuel. According to a preferred variant, there is provided a ring or a tab which is integral with the sealing ring and which extends along the external lateral wall of the head. This tab or this ring makes it possible to note the presence of the sealing ring after installation by a simple visual examination.
Pour que la bague d'étanchéité ne puisse pas se détacher de la tête du rivet, il est prévu avantageusement un talon annulaire qui est d'un seul tenant avec l'anneau et qui s'encastre dans la tête en affleurant la face supérieure de la tête. Il est également possible de fixer la bague sur la tête par exemple par collage, clipsage ou surmoulage. So that the sealing ring cannot be detached from the head of the rivet, an annular heel is advantageously provided which is integral with the ring and which is embedded in the head by flush with the upper face of the head. It is also possible to fix the ring on the head, for example by gluing, clipping or overmolding.
Lorsque le talon fait saillie de la face supérieure de la tête, il forme un joint d'étanchéité entre la tête et une seconde pièce venant se visser sur le rivet. When the heel protrudes from the upper face of the head, it forms a seal between the head and a second piece which is screwed onto the rivet.
La bague d'étanchéité est de préférence en matière plastique, en caoutchouc. The sealing ring is preferably made of plastic, rubber.
Au dessin annexé, donné uniquement à titre d'exemple
la figure 1 est une vue en élévation d'un rivet suivant l'invention, partiellement en coupe, avant la pose,
la figure 2 est une vue correspondant à la figure 1, après la pose, et
les figures 3 et 4 sont des vues correspondant aux figures 1 et 2 d'une variante.In the accompanying drawing, given only by way of example
FIG. 1 is an elevation view of a rivet according to the invention, partially in section, before installation,
FIG. 2 is a view corresponding to FIG. 1, after installation, and
Figures 3 and 4 are views corresponding to Figures 1 and 2 of a variant.
Le rivet tubulaire représenté aux figures 1 et 2 comprend un fût 1 cylindrique de section droite circulaire, dont la paroi intérieure porte un taraudage 2. Le fût 1 est prolongé par une tête 3 qui fait saillie radialement de la paroi extérieure du fût 1. The tubular rivet shown in FIGS. 1 and 2 comprises a cylindrical barrel 1 of circular cross section, the internal wall of which carries a thread 2. The barrel 1 is extended by a head 3 which projects radially from the external wall of the barrel 1.
Une bague d'étanchéité 4 de même axe que le fût 1 est logée dans une cavité 5 annulaire qui débouche sur la face inférieure de la tête 3.A sealing ring 4 of the same axis as the barrel 1 is housed in an annular cavity 5 which opens onto the underside of the head 3.
Un anneau 6, d'un seul tenant avec la bague 4, s'étend le long de la paroi latérale extérieure de la tête 3. Un talon 7 annulaire, d'un seul tenant avec l'anneau 6, s'encastre dans la tête 3 en affleurant la face supérieure de la tête 3. A ring 6, in one piece with the ring 4, extends along the outer lateral wall of the head 3. An annular heel 7, in one piece with the ring 6, fits into the head 3 by being flush with the upper face of head 3.
Le fût 1 est destiné à s'engager dans un trou 8 polygonal ménagé dans une pièce P. The barrel 1 is intended to engage in a polygonal hole 8 formed in a part P.
Avant la pose (figure 1) le bord intérieur de la bague 4 est à une certaine distance radiale D de la paroi extérieure du fût 1. Cette distance D est supérieure à la distance radiale d entre la surface latérale définissant le trou 8 et la paroi extérieure du fût 1. Before installation (Figure 1) the inner edge of the ring 4 is at a certain radial distance D from the outer wall of the barrel 1. This distance D is greater than the radial distance d between the lateral surface defining the hole 8 and the wall outside of barrel 1.
Lors de la pose (figure 2), la bague 4 est serrée entre la tête 3 et la pièce P et flue radialement sans possibilité de pénétrer dans le trou 8 dans l'intervalle compris entre la pièce P et le fût 1. During installation (Figure 2), the ring 4 is clamped between the head 3 and the part P and flows radially without the possibility of penetrating the hole 8 in the interval between the part P and the barrel 1.
L'étanchéité est donc bien assurée. Sealing is therefore well ensured.
Aux figures 3 et 4, le talon 9 annulaire, qui est d'un seul tenant avec l'anneau 6, fait saillie de la face supérieure de la tête 3 et forme ainsi un joint entre celle-ci et une pièce (non représentée) destinée à être vissée dans le taraudage 2. In FIGS. 3 and 4, the annular heel 9, which is integral with the ring 6, projects from the upper face of the head 3 and thus forms a joint between the latter and a part (not shown) intended to be screwed into the internal thread 2.
