Dans ces dispositifs, le mode de fixation utilise le principe de déformation du ressort d'attache pour l'amener de la position libre à la position serrée sur le patin du rail.In these devices, the method of attachment uses the principle of deformation of the attachment spring to bring it from the free position to the clamped position on the rail pad.
La présente invention a pour but de résoudre de façon simple les problèmes techniques liés au prémontage et à la mécanisation de pose des dispositifs de fixation comprenant des attaches.The object of the present invention is to solve in a simple manner the technical problems linked to the pre-assembly and to the mechanization of laying of the fixing devices comprising fasteners.
Conformément à l'invention, le dispositif de fixation comporte : - un ressort d'attache formant un moyen de fixation ou de serrage du rail sur son support, constitué par une attache métallique déformable de façon élastique ayant deux branches symétriques ; chacune des branches comportant une extrémité et présentant successivement depuis cette extrémité un premier tronçon sensiblement horizontal, un deuxième tronçon formant un coude sensiblement à 180°, un troisième tronçon, un quatrième tronçon formant un coude sensiblement à 180°, un cinquième tronçon disposé transversalement par rapport au premier tronçon et formant aussi liaison avec l'autre branche, - un organe d'ancrage ou insert destiné à recevoir le ressort d'attache et fixé par ailleurs dans le support de rail, et est caractérisé en ce que ledit insert comprend un plan incliné sur lequel sont prévus un organe de pivotement et de retenue verticale de ladite attache et des moyens de guidage et de blocage en rotation de ladite attache en position d'appui sur le patin du rail.According to the invention, the fixing device comprises: - a fastening spring forming a means for fixing or clamping the rail on its support, constituted by a metal fastener which is elastically deformable and has two symmetrical branches; each of the branches having an end and having successively from this end a first substantially horizontal section, a second section forming a substantially 180 ° bend, a third section, a fourth section forming a substantially 180 ° bend, a fifth section disposed transversely by relative to the first section and also forming a connection with the other branch, - an anchoring member or insert intended to receive the fastening spring and fixed elsewhere in the rail support, and is characterized in that said insert comprises a inclined plane on which there are provided a member for pivoting and vertical retaining of said fastener and means for guiding and blocking in rotation of said fastener in the support position on the shoe of the rail.
Selon une autre caractéristique de l'invention, ladite attache comporte des moyens d'accrochage sur ledit organe de pivotement et de retenue verticale, lesdits moyens d'accrochage étant constitués d'une boucle ouverte réalisée sur le premier tronçon de ladite attache et adaptée pour venir s'engager de façon amovible, par déformation élastique sur ledit organe de pivotement et de retenue verticale.According to another characteristic of the invention, said attachment comprises attachment means on said pivoting and vertical retaining member, said attachment means being constituted by an open loop produced on the first section of said attachment and adapted for come to engage removably, by elastic deformation on said pivot member and vertical retention.
Selon encore une autre caractéristique, ledit organe de pivotement et de retenue verticale comprend un tourillon sensiblement vertical surmonté d'un chapeau débordant, ledit tourillon formant axe de rotation pour la mise en place de l'attache en appui contre le rail et ledit chapeau interdisant tout dégagement vertical intempestif de l'attache. Toujours selon l'invention, lesdits moyens de guidage et de blocage en rotation comprennent au moins deux séries de saignées réalisées sur ledit plan incliné, l'une étant réalisée autour du tourillon pour recevoir au moins partiellement la boucle de l'attache et l'autre s'étendant de façon sensiblement transversale par rapport au rail pour recevoir au moins partiellement un des tronçons rectilignes de l'attache.According to yet another characteristic, said pivoting and vertical retaining member comprises a substantially vertical journal surmounted by an overhanging cap, said journal forming an axis of rotation for the positioning of the fastener bearing against the rail and said cap preventing any untimely vertical release of the fastener. Still according to the invention, said means for guiding and blocking in rotation comprise at least two series of grooves made on said inclined plane, one being produced around the pin to at least partially receive the loop of the fastener and the another extending substantially transversely to the rail to receive at least partially one of the straight sections of the fastener.

La figure 8 est une épure schématique vue en bout d'une même attache avant et après rotation. Les figures 1 et 2 représentent l'assemblage du rail R sur son support 1 comprenant une traverse, une selle ou une dalle , au moyen du dispositif de l'invention.Figure 8 is a schematic sketch seen at the end of the same fastener before and after rotation. Figures 1 and 2 show the assembly of the rail R on its support 1 comprising a cross member, a saddle or a slab, by means of the device of the invention.
Le dispositif de fixation de l'invention comprend un ressort d'attache formant un moyen de fixation ou de serrage du rail R sur son support 1, constitué par une attache métallique 2 déformable de façon élastique, ayant deux branches symétriques 2a, 2b, et un organe d'ancrage ou insert 3 destiné à recevoir le ressort d'attache et fixé par ailleurs dans le support 1 de rail R.The fixing device of the invention comprises a fastening spring forming a means for fixing or tightening the rail R on its support 1, constituted by a metal fastener 2 elastically deformable, having two symmetrical branches 2a, 2b, and an anchoring member or insert 3 intended to receive the fastening spring and also fixed in the support 1 of rail R.
L'insert 3 comprend un plan incliné 31 sur lequel sont prévus un organe de pivotement et de retenue verticale de ladite attache 2 et des moyens de guidage et de blocage en rotation de ladite attache en position d'appui sur le patin du rail.The insert 3 comprises an inclined plane 31 on which are provided a member for pivoting and vertical retaining of said fastener 2 and means for guiding and blocking the rotation of said fastener in the support position on the rail pad.
L'organe de pivotement et de retenue verticale selon l'invention comprend un tourillon sensiblement vertical 37 surmonté d'un chapeau débordant 33. L'axe 32 du tourillon 37 forme axe de rotation pour la mise en place de l'attache 2 en appui contre le rail. Le chapeau débordant 33 interdit quant à lui tout dégagement vertical intempestif de l'attache 2.The pivoting and vertical retaining member according to the invention comprises a substantially vertical pin 37 surmounted by an overhanging cap 33. The axis 32 of the pin 37 forms an axis of rotation for the positioning of the fastener 2 in support against the rail. The overflowing cap 33 prohibits any untimely vertical release of the fastener 2.
Selon une variante de réalisation, le tourillon est remplacé par un tirefond indépendant. Le plan incliné 31 permet à l'attache 2, lors de sa mise en place sur le rail par rotation, de monter progressivement pour atteindre le niveau du dessus du patin du rail R.According to an alternative embodiment, the journal is replaced by an independent lag screw. The inclined plane 31 allows the fastener 2, when it is placed on the rail by rotation, to progressively rise to reach the level of the top of the shoe of the rail R.
Le dispositif représenté sur les figures 1 et 2 comprend également un intercalaire isolant 41 monté entre le bord latéral du patin du rail sur lequel il repose au moins partiellement, et leditThe device shown in Figures 1 and 2 also includes an insulating insert 41 mounted between the side edge of the shoe of the rail on which it rests at least partially, and said
• insert 3. L'intercalaire isolant 41 est destiné à recevoir au moins un tronçon de l'attache 2 en contact d'appui sur une portion 43.• insert 3. The insulating interlayer 41 is intended to receive at least one section of the fastener 2 in contact with support on a portion 43.
Entre le rail R et son support 1, est disposé une semelle élastique et amortissante 40.Between the rail R and its support 1, an elastic and damping sole 40 is disposed.
La figure 3 montre en vue de dessus les attaches avant et après serrage. L'attache 2A est représentée en position avant serrage mais déjà prémontée sur son iπsert. L'attache 2P est représentée en position serrée. Le mode opératoire est le suivant : Une fois que l'on a déposé le rail R et que l'on a introduit les deux intercalaires 41 de part et d'autre du patin du rail, on fait tourner les deux attaches. Elles passent ainsi de la position 2A à la position 2P.Figure 3 shows a top view of the fasteners before and after tightening. The fastener 2A is shown in position before tightening but already pre-assembled on its iπsert. The 2P fastener is shown in the tight position. The operating mode is as follows: Once the rail R has been removed and the two spacers 41 have been inserted on either side of the rail pad, the two fasteners are rotated. They thus pass from position 2A to position 2P.
La figure 4 est une vue en perspective de l'attache 2 à l'état libre. L'attache 2 possède deux branches symétriques 2a, 2b.Figure 4 is a perspective view of the fastener 2 in the free state. The fastener 2 has two symmetrical branches 2a, 2b.
Dans un premier mode de réalisation, chacune des branchesIn a first embodiment, each of the branches
2a, 2b comporte une extrémité 21a, 21b et présente successivement depuis cette extrémité un premier tronçon sensiblement horizontal2a, 2b has one end 21a, 21b and successively has from this end a first substantially horizontal section
26 , un deuxième tronçon 25 formant un coude sensiblement à 180°, un troisième tronçon 24, un quatrième tronçon 23 formant un coude sensiblement à 180°, un cinquième tronçon 22 disposé transversalement par rapport au premier tronçon 21-26 et formant aussi liaison avec l'autre branche.26, a second section 25 forming a substantially 180 ° bend, a third section 24, a fourth section 23 forming a substantially 180 ° bend, a fifth section 22 disposed transversely to the first section 21-26 and also forming a connection with the other branch.
Dans un autre mode de réalisation (non représenté) , chacune des branches 2a, 2b comporte une extrémité 22a, 22b et présente successivement depuis cette extrémité un premier tronçon 22' sensiblement horizontal , un deuxième tronçon 23' formant un coude sensiblement à 180°, un troisième tronçon 24' , un quatrième tronçon 25' formant un coude sensiblement à 180°, un cinquième tronçon 26' disposé transversalement par rapport au premier tronçon 22' et formant aussi liaison avec l'autre branche par le biais d'une boucle fermée 21'.In another embodiment (not shown), each of the branches 2a, 2b has one end 22a, 22b and successively has from this end a first section 22 'substantially horizontal, a second section 23' forming a bend substantially at 180 °, a third section 24 ', a fourth section 25' forming a substantially 180 ° bend, a fifth section 26 'arranged transversely to the first section 22 'and also forming a connection with the other branch by means of a closed loop 21'.
L'attache 2 comporte des moyens d'accrochage sur l'organe de pivotement et de retenue verticale de l'insert 3. Ces moyens d'accrochage sont constitués d'une boucle ouverte 21 réalisée sur le premier tronçon 26 de ladite attarhe et adaptée pour venir s'engager de façon amovible, par déformation élastique sur ledit organe de pivotement et de retenue verticale.The fastener 2 comprises hooking means on the pivot member and vertical retaining of the insert 3. These hooking means consist of an open loop 21 made on the first section 26 of said clip and adapted to come to engage removably, by elastic deformation on said pivot member and vertical retention.
Dans le mode de réalisation représenté sur les figures, la boucle ouverte 21 est discontinue , en étant coupée en son milieu pour définir les deux extrémités 21a, 21b. Les deux branches de la boucle 21 ayant respectivement pour extrémité 21a, 21b, restent prisonnières sous la tête du tourillon 37 formée par le chapeau débordant 33. On peut concevoir un autre mode de réalisation dans lequel la boucle ouverte 21 est continue et est engagée sous le chapeau débordant 33 par déformation élastique des tronçons 26.In the embodiment shown in the figures, the open loop 21 is discontinuous, being cut in the middle to define the two ends 21a, 21b. The two branches of the loop 21 having respectively the ends 21a, 21b, remain trapped under the head of the pin 37 formed by the projecting cap 33. It is possible to imagine another embodiment in which the open loop 21 is continuous and is engaged under the overflowing cap 33 by elastic deformation of the sections 26.
L'attache 2 est fabriquée à partir d'un fil de métal d'une certaine longueur, par pliages successifs. Le fil de métal constituant l'attache 2 est en principe de section ronde mais peut présenter un écrasement localisé plus ou moins prononcé pour éviter les pressions de contact trop élevées soit sur l'intercalaire isolant , soit sur le patin du rail lui-même.The fastener 2 is made from a metal wire of a certain length, by successive folding. The metal wire constituting the fastener 2 is in principle of round section but may have a more or less pronounced localized crushing to avoid excessively high contact pressures either on the insulating interlayer or on the shoe of the rail itself.
On peut concevoir également d'autres modes de réalisation dans lesquels l'attache 2 est réalisée en fil de section carrée. La figure 5 est une vue en perspective de l'insert 3. L'insert 3 comprend un tourillon 37 d'axe 32 surmonté par un chapeau débordant 33.Le tourillon 37 est fixé rigidement et à demeure dans le support 1. La face avant 35 de l'insert 3 va servir de butée latérale au rail .Le plan incliné 31 permet à l'attache 2 de monter progressivement lors de la rotation sur l'intercalaire 41 ou sur le dessus du patin du rail.One can also conceive other embodiments in which the fastener 2 is made of wire of square section. Figure 5 is a perspective view of the insert 3. The insert 3 comprises a pin 37 of axis 32 surmounted by a projecting cap 33. The pin 37 is rigidly fixed and permanently in the support 1. The front face 35 of the insert 3 will serve as a lateral stop for the rail. The inclined plane 31 allows the fastener 2 to rise progressively during rotation on the interlayer 41 or on the top of the shoe of the rail.
L'insert 3 comprend également des moyens de guidage et de blocage en rotation de l'attache 2.Ces moyens comprennent deux séries de saignées 34, 36, réalisées sur le plan incliné 31. Les saignées 36 ne sont toutefois pas indispensables et peuvent être remplacées par un taquet d'arrêt prohéminant (non représenté sur le dessin) n'autorisant la rotation de l'attache autour de l'axe 32 que dans un seul sens, en servant de butée à l'une des deux branches 26 de l'attache. La série de saignées 34 est réalisée à la base et autour du tourillon 37 pour recevoir au moins partiellement la boucle 21 de l'attache 2. La série de saignées 36 s'étend de façon sensiblement transversale par rapport au rail pour recevoir au moins partiellement un des tronçons rectilignes 26 de l'attache 2 lorsque celle-ci a été positionnée en contact d'appui sur le rail.The insert 3 also includes means for guiding and blocking the fastener 2 in rotation. These means comprise two series of grooves 34, 36, produced on the inclined plane 31. The grooves 36 are not, however, essential and can be replaced by a prominent stopper (not shown in the drawing) allowing rotation of the fastener around the axis 32 only in one direction, serving as a stop to one of the two branches 26 of the fastener. The series of grooves 34 is made at the base and around the pin 37 to at least partially receive the loop 21 of the clip 2. The series of grooves 36 extends substantially transversely relative to the rail to receive at least partially one of the rectilinear sections 26 of the fastener 2 when the latter has been positioned in bearing contact on the rail.
La figure 6 est une vue en perspective de l'intercalaire isolant 41 • schématisé sur les vues précédentes. L'intercalaire isolant 41 est muni de deux rebords latéraux 44 qui sont destinés à venir de part et d'autre de l'insert 3 pour éviter tout mouvement dudit intercalaire 41 parallèlement au rail entre l'iπsert 3 et le patin du rail.Figure 6 is a perspective view of the insulating insert 41 • shown schematically in the previous views. The insulating interlayer 41 is provided with two lateral flanges 44 which are intended to come on either side of the insert 3 to prevent any movement of said interlayer 41 parallel to the rail between the iπsert 3 and the shoe of the rail.
L'intercalaire 41 est muni de deux saillies latérales 45 s'étendant dans le prolongement des rebords 44 et reliées à la portion intermédiaire 43 sur laquelle l'attache est en contact d'appui, par l'intermédiaire de parties courbes 45a destinées à coopérer au moins partiellement avec les tronçons coudés de l'attache 2, de telle sorte que après rotation de l'attache, le tronçon rectiligne 22 vienne se loger entre les deux saillies latérales 45 en contact d'appui sur la portion 43 et ne puisse plus tourner de façon intempestive. Dans ce dernier cas, pour démonter l'attache, il est nécessaire d'exercer un couple de déblocage suffisant pour que le tronçon 22 surmonte l'obstacle constitué de la saillie 45. La partie 42 de l'insert 3 est destinée à encaisser les efforts latéraux et à isoler électriquement le bord du patin du rail de l'insert 3.The interlayer 41 is provided with two lateral projections 45 extending in the extension of the flanges 44 and connected to the intermediate portion 43 on which the fastener is in bearing contact, by means of curved parts 45a intended to cooperate at least partially with the bent sections of the fastener 2, so that after rotation of the fastener, the straight section 22 comes to lodge between the two lateral projections 45 in contact with support on the portion 43 and can no longer untimely turning. In the latter case, to disassemble the fastener, it is necessary to exert a sufficient release torque so that the section 22 overcomes the obstacle consisting of the projection 45. The part 42 of the insert 3 is intended to collect the lateral forces and electrically isolate the edge of the pad from the rail of the insert 3.
La figure 7 illustre l'opération de mise en place de l'attache 2 sur 1*insert 3. On effectue d'abord le mouvement en translation Dl de l'attache 2 vers l'insert 3 jusqu'à ce que les tronçons coudés 25 viennent au contact de la paroi latérale du tourillon 37. Une poussée sensiblement horizontale dans le sens de Dl contre le tourillon 37 produit un écartement D2 et branches 2a,2b qui permet la mise en place de la boucle 21 autour du tourillon 37. La boucleFIG. 7 illustrates the operation of fitting the fastener 2 onto the insert 3. First, the movement in translation Dl of the fastener 2 towards the insert 3 until the bent sections 25 come into contact with the side wall of the pin 37. A substantially horizontal thrust in the direction of Dl against the pin 37 produces a spacing D2 and branches 2a, 2b which allows the establishment of the loop 21 around the pin 37. The loop
21 se referme ensuite élastiquement autour du tourillon 37. L'attache 2 est ainsi prémontée sur l1insert 3.21 then closes elastically around the pin 37. The fastener 2 is thus preassembled on the 1 insert 3.
L'opération suivante consiste à faire pivoter autour de l'axe 32 du tourillon 37 l'attache 2 en forçant le tronçon 22 à monter le long du plan incliné 31 et en l'aidant à franchir les obstacles constitués des saillies 45. La rotation de l'attache 2 autour de l'axe 32 du tourillon 37 est facilitée au moyen de la saignée 34 ménagée à la base du tourillon 37 sur le plan incliné 31. Une fois l'attache 2 en contact d'appui par son tronçonThe following operation consists in pivoting around the axis 32 of the pin 37 the fastener 2 by forcing the section 22 to rise along the inclined plane 31 and by helping it to overcome the obstacles constituted by the projections 45. The rotation of the clip 2 around the axis 32 of the pin 37 is facilitated by means of the groove 34 formed at the base of the pin 37 on the inclined plane 31. Once the clip 2 in contact with support by its section
22 sur la partie 43 de l'intercalaire 41, lui-même en appui sur le patin du rail, les tronçons 26 sont maintenus en position transversale par rapport au patin du rail au moyen des saignées 36 dans lesquelles ils reposent. La figure 8 représente en trait plein l'attache 2A prémontée avant rotation autour du tourillon 37 et en trait mixte l'attache 2P après rotation, c'est-à-dire en position de serrage du rail. L'axe 32 et l'axe de rotation 22A et 22P sont les traces de la branche 22 avant et après rotation. est la déflexion de mise en place de l'attache. Cette déflexion correspond à la pente du plan incliné 31. 22 on the part 43 of the interlayer 41, itself bearing on the shoe of the rail, the sections 26 are maintained in transverse position relative to the shoe of the rail by means of the grooves 36 in which they rest. FIG. 8 shows in solid line the clip 2A preassembled before rotation around the pin 37 and in phantom in the clip 2P after rotation, that is to say in the rail clamping position. The axis 32 and the axis of rotation 22A and 22P are the traces of the branch 22 before and after rotation. is the deflection of fitting the fastener. This deflection corresponds to the slope of the inclined plane 31.
