La figure 2 est une vue en perspective de la pince selon l'invention. La figure 3 est une vue de dessus de la seconde pièce en forme de bande de la pince selon l'invention. La figure 4 est une vue de côté de la seconde pièce en forme de bande de la pince selon l'invention.Figure 2 is a perspective view of the clamp according to the invention. Figure 3 is a top view of the second strip-shaped part of the clamp according to the invention. Figure 4 is a side view of the second strip-shaped part of the clamp according to the invention.
La figure 5 est une vue en perspective d'un second exemple de réalisation de la pince selon l'invention.Figure 5 is a perspective view of a second embodiment of the clamp according to the invention.
Sur la figure 1 , on a représenté en partie une fourrure 1 qui sert à la pose d'un revêtement de plafond pour la rénovation de bâtiments principalement. La fourrure 1 en forme de rail à section en U possède deux flancs 2 qui se font face et dont les bords longitudinaux sont recourbés à 90° pour définir deux lèvres 3 qui permettent de réaliser un assemblage par coincement avec une pince 4 selon l'invention en exerçant un mouvement de VS de tour de la pince entre les deux flancs 2 schématisé par un arc de flèche sur la figure 1.In Figure 1, there is shown in part a fur 1 which is used for the installation of a ceiling covering for the renovation of buildings mainly. The fur 1 in the form of a U-section rail has two flanks 2 which face each other and whose longitudinal edges are curved at 90 ° to define two lips 3 which allow an assembly to be made by wedging with a clamp 4 according to the invention by exerting a turn VS movement of the clamp between the two flanks 2 schematized by an arrow arc in Figure 1.
La pince 4 présente un passage ici sensiblement cylindrique traversé pour une tige filetée 5 par exemple. Ce passage est défini par un certain alignement de deux orifices réalisés dans deux lames superposées faisant partie respectivement de deux pièces distinctes 6 et 7 qui s'insèrent l'une dans l'autre. Comme visible sur la figure 2, la pince 4 selon l'invention comprend donc une première pièce profilée 6 qui a une section transversale sensiblement en forme de U à deux branches 8 et 9.The clamp 4 has a substantially cylindrical through passage for a threaded rod 5 for example. This passage is defined by a certain alignment of two holes made in two superimposed blades respectively part of two separate parts 6 and 7 which fit into one another. As can be seen in FIG. 2, the clamp 4 according to the invention thus comprises a first profiled part 6 which has a substantially U-shaped cross section with two branches 8 and 9.
La pièce 6 a une semelle plane 10 constituant une des deux lames superposées. Cette semelle 10 est sensiblement perpendiculaire aux montants formés par les branches 8 et 9 du U. Quatre encoches longitudinales (dont trois 8A,8B,9A sont visibles sur la figure) sont formées respectivement dans les bords latéraux des montants. Ces encoches coplanaires sont agencées pour recevoir les lèvres 3 de la fourrure 1 lors du mouvement de VA de tour par exemple dans le sens horaire inverse de la pièce 6 dans la fourrure 1 comme illustré sur la figure 1. Les coins des bords latéraux des montants peuvent être biseautés pour éliminer la présence de parties saillantes. La première pièce 6 est réalisée en un matériau rigide par exemple par pliage d'une tôle métallique.The piece 6 has a flat sole 10 constituting one of the two superimposed blades. This sole 10 is substantially perpendicular to the uprights formed by the branches 8 and 9 of the U. Four longitudinal notches (three of which 8A, 8B, 9A are visible in the figure) are formed respectively in the side edges of the uprights. These coplanar notches are arranged to receive the lips 3 of the fur 1 during the movement of turn VA for example in the opposite clockwise direction of the piece 6 in the fur 1 as illustrated in FIG. 1. The corners of the lateral edges of the uprights can be beveled to eliminate the presence of protruding parts. The first piece 6 is made of a rigid material for example by folding a metal sheet.
La seconde pièce 7 se présente sous la forme d'une bande flexible ayant une partie frontale plane 11 sensiblement rectiligne qui constitue la seconde lame et une partie arrière courbée 12 en forme de S formant un ressort. La partie frontale 11 de la pièce 7 s'insère dans des fentes 13,14 parallèles à la semelle 10 et formées en se faisant face respectivement dans les deux montants 8,9 de la pièce 6, ici au niveau des deux plis entre la semelle et chaque montant respectivement.The second piece 7 is in the form of a flexible strip having a substantially rectilinear flat front portion 11 which constitutes the second blade and a curved rear portion 12 in the shape of a S forming a spring. The front portion 11 of the piece 7 fits into slots 13, 14 parallel to the sole 10 and formed facing each other in the two uprights 8, 9 of the piece 6, here at the two folds between the sole. and each amount respectively.
Comme visible sur la figure 2, les fentes 13,14 s'étendent selon une direction longitudinale de la semelle 10 dans un même plan de sorte que les deux lames 10 et 11 sont sensiblement parallèles.As visible in Figure 2, the slots 13,14 extend in a longitudinal direction of the sole 10 in the same plane so that the two blades 10 and 11 are substantially parallel.
La référence 15 désigne un orifice qui est formé sensiblement au centre de la semelle 10. Cet orifice a un diamètre légèrement plus grand que le diamètre de la tige 5. On voit que cet orifice coïncide avec un autre orifice formé dans la partie frontale rectiligne 11.The reference 15 designates an orifice which is formed substantially in the center of the soleplate 10. This orifice has a diameter slightly larger than the diameter of the rod 5. It can be seen that this orifice coincides with another orifice formed in the rectilinear front part 11 .
Les figures 3 et 4 montrent la pièce 7 avec sa partie frontale 11 munie d'un orifice 16 et sa partie arrière 12 courbée en S formant ressort. Le bord d'extrémité avant de la partie frontale 11 présente une forme relativement arrondie, ici avec deux arrondis partant respectivement des bords latéraux de la partie frontale 11 ce qui facilite son insertion dans les fentes 13 et 14 de la pièce 6.Figures 3 and 4 show the part 7 with its front portion 11 provided with an orifice 16 and its rear portion 12 curved S forming spring. The front end edge of the front portion 11 has a relatively rounded, here with two roundings starting respectively from the side edges of the front portion 11 which facilitates its insertion into the slots 13 and 14 of the part 6.
L'orifice 16 est formé par deux trous circulaires sécants de diamètres différents et espacés l'un de l'autre d'un entraxe E selon la direction axiale D de la pièce 7. Cet orifice est formé sensiblement au milieu de la pièce 7.The orifice 16 is formed by two intersecting circular holes of different diameters and spaced apart from each other by a spacing E in the axial direction D of the part 7. This orifice is formed substantially in the middle of the part 7.
Une patte inclinée flexible anti-retour 17 est formée par exemple par découpe dans la bande de la partie frontale 11 entre l'orifice 16 et la partie arrière 12 de la pièce 7. Cette patte 17 saille en faisant un angle d'environA non-return flexible inclined lug 17 is formed for example by cutting in the band of the front part 11 between the orifice 16 and the rear part 12 of the part 7. This lug 17 protrudes at an angle of about
45° du côté de la concavité de la bande formée par la courbure de la partie arrière 12 formant le ressort.45 ° on the side of the concavity of the band formed by the curvature of the rear portion 12 forming the spring.
La partie frontale 11 de la pièce 7 est donc insérée dans les fentes 13,14 de la pièce 6 selon une certaine direction d'insertion (indiquée par la flèche I sur la figure 2) jusqu'à ce que la patte anti-retour 17 traverse dans le cas d'exemple de la figure 2 la fente 13 et que le bord d'extrémité de la partie arrière courbée 12 vienne en butée contre la surface extérieure du montant 8. Ou fait que la patte 17 est flexible, elle s'efface d'abord dans la fente 13 puis se détend contre la surface intérieure du montant 8. Selon l'invention, en position d'insertion complète de la pièce 7 dans la pièce 6, la partie arrière courbée 12 formant ressort de la pièce 7 et la patte anti-retour 17 sont agencées de telle manière à exercer respectivement de part et d'autre du montant 8 de la pièce 6 des forces de rappel opposées selon la direction d'insertion (correspondant à la direction D) empêchant un déplacement de la pièce 7 dans la pièce 6 selon une direction opposée à la direction d'insertion. Dans la position d'insertion complète de la pièce 7 dans la pièce 6, l'extrémité de la partie frontale 11 de la pièce 7 dépasse assez largement la fente 14 vers l'extérieur de la pièce 6 pour assurer un assemblage solide. Cet agencement permet d'éviter un démontage intempestif de l'assemblage. On peut prévoir avantageusement que par rapport à un plan qui est transversal au plan de la partie frontal 11 , la partie arrière courbée 12 est espacée de la patte anti-retour 17 d'une distance légèrement inférieure à l'épaisseur du montant 8 de la pièce 6 ce qui fait que le verrouillage ferme de la tige dans la pince est obtenu sans solliciter une contrainte importante de du ressort 12 de la seconde pièce. L'orifice 16 de la pièce 7 comporte un premier trou 16A ici circulaire de plus grand diamètre que le diamètre de la tige 5 et un second trou 16B d'un diamètre plus petit que celui du trou 16 A mais sensiblement identique au diamètre de la tige 5 en fond de filets de manière à ce que, avec une épaisseur appropriée de la pièce 7, le second trou 16B se ferme sur la demi- périphérie de la tige entre deux filets consécutifs. Les deux trous 16A et 16B sont sécants et alignés axialement selon la direction D de telle manière à former une sorte de fente oblongue de coulissement pour la tige 5.The front portion 11 of the piece 7 is inserted in the slots 13,14 of the piece 6 in a certain direction of insertion (indicated by the arrow I in Figure 2) until the non-return tab 17 crosses in the case of example of Figure 2 the slot 13 and the end edge of the curved rear portion 12 abuts against the outer surface of the upright 8. Or that the tab 17 is flexible, it s' erases firstly in the slot 13 and then relaxes against the inner surface of the upright 8. According to the invention, in the fully inserted position of the piece 7 in the piece 6, the curved rear portion 12 forming a spring of the piece 7 and the non-return tab 17 are arranged so as to respectively exert on each side of the upright 8 of the workpiece 6 opposing return forces in the direction of insertion (corresponding to the direction D) preventing a displacement of room 7 in room 6 in an opposite direction e to the insertion direction. In the position of complete insertion of the part 7 in the part 6, the end of the front portion 11 of the part 7 extends far enough beyond the slot 14 towards the outside of the part 6 to ensure a solid assembly. This arrangement prevents untimely disassembly of the assembly. It can be advantageously provided that with respect to a plane which is transverse to the plane of the front portion 11, the curved rear portion 12 is spaced from the non-return tab 17 a distance slightly less than the thickness of the upright 8 of the piece 6 so that the locking of the rod in the clamp is obtained without soliciting a significant stress of the spring 12 of the second piece. The orifice 16 of the part 7 comprises a first hole 16A here circular larger diameter than the diameter of the rod 5 and a second hole 16B of a diameter smaller than that of the hole 16A but substantially identical to the diameter of the rod 5 at the bottom of the threads so that, with an appropriate thickness of the part 7, the second hole 16B closes on the half-periphery of the rod between two consecutive threads. The two holes 16A and 16B are intersecting and axially aligned in the direction D so as to form a kind of oblong sliding slot for the rod 5.
Quand on exerce une force selon la direction d'insertion sur la partie arrière courbée 12 formant ressort de la pièce 7 qui est insérée complètement dans la pièce 6 laquelle est immobilisée, on comprime ce ressort et en même temps on provoque un déplacement relatif en translation de la partie frontale 11 par rapport à la semelle 10 tendant à mettre en coïncidence axiale le trou 16A et le trou 15 ce qui permet un déplacement axial de la tige 5 dans le passage formé par ces deux trous. Quand on relâche cette contrainte sur le ressort, la partie arrière courbée 12 se détend naturellement et exerce une force de détente provoquant un déplacement en translation de la partie frontale 11 par rapport à la semelle 10 tendant à faire passer l'axe du trou 16 A en arrière de l'axe du trou 15 de telle sorte à bloquer le déplacement axial de la tige 5 dans le passage formé cette fois par les trous 16A et 15, ceci par un effet de cisaillement des bords périphériques de ces trous. Plus particulièrement, dans cet état de relâchement de contrainte, les bords périphériques des trous 16B et 15 viennent pincer la tige et la verrouillent dans la pince 4.When a force is exerted in the direction of insertion on the curved rear portion 12 forming the spring of the part 7 which is inserted completely into the part 6 which is immobilized, this spring is compressed and at the same time causes a relative translation displacement. of the front portion 11 relative to the soleplate 10 tending to axially coincide the hole 16A and the hole 15 which allows axial displacement of the rod 5 in the passage formed by these two holes. When this stress is released on the spring, the curved rear portion 12 naturally relaxes and exerts a triggering force causing a translational movement of the front portion 11 relative to the soleplate 10 tending to move the axis of the hole 16 A behind the axis of the hole 15 so as to block the axial displacement of the rod 5 in the passageway formed by the holes 16A and 15, this by a shearing effect of the peripheral edges of these holes. More particularly, in this state of stress relaxation, the peripheral edges of the holes 16B and 15 pinch the rod and lock it in the clamp 4.
La pièce 7 peut être réalisée dans une tôle en acier à ressort découpée et déformée. L'élasticité nécessaire au bon fonctionnement du ressort 12 peut être obtenue de façon connue, par exemple par un traitement thermique de l'acier utilisé pour la pièce 7.The piece 7 can be made in a spring steel sheet cut and deformed. The elasticity necessary for the proper functioning of the spring 12 can be obtained in known manner, for example by a heat treatment of the steel used for the part 7.
Sur figure 5, on représenté une pince 4' selon l'invention dans laquelle la seconde pièce T comportant une partie frontale 11' coulisse dans deux rainures se faisant face formées par des pattes recourbées 18' saillant depuis la surface inférieure de la semelle 10' de la première pièce 6'. Ces rainures empêchent un déplacement transversal à la direction d'insertion de la seconde pièce dans la première pièce. Les pattes recourbées 18' peuvent être formées par une découpe de la semelle 10' en tôle.FIG. 5 shows a gripper 4 'according to the invention in which the second piece T having a front portion 11' slides in two facing grooves formed by curved legs 18 'projecting from the lower surface of the sole 10 'of the first piece 6'. These grooves prevent displacement transverse to the insertion direction of the second piece in the first piece. The bent tabs 18 'may be formed by a cutout of the sole plate 10' sheet.
La seconde pièce T peut également être munie de deux pattes flexibles 17' alignées selon une direction perpendiculaire à la direction d'insertion pour obtenir ou conforter ce blocage d'un mouvement transversal de la seconde pièce dans la première pièce.The second piece T may also be provided with two flexible tabs 17 'aligned in a direction perpendicular to the direction of insertion to obtain or reinforce this blockage of a transverse movement of the second piece in the first piece.
La pince selon l'invention est d'une manipulation aisée. Le réglage du niveau des fourrures peut se faire aisément car il est possible d'une seule main d'exercer une pression sur la partie courbée de la seconde pièce tout en maintenant fermement la première pièce pour régaler la position de la tige dans la pince. Ces deux pièces peuvent être produites par découpe, pliage et déformation d'une tôle métallique peu onéreuse. En plus, lorsque la patte flexible anti-retour se détend après son passage dans une fente de la première pièce, il se produit un signal sonore qui sert de témoin pour vérifier simplement que l'assemblage de la seconde pièce dans la première pièce s'est bien réalisé. On peut également disposer sans sortir du cadre de l'invention la ou les pattes flexibles anti-retour à l'extrémité de la partie frontale de la seconde pièce pour un appui contre la face extérieure du montant 9 de la première pièce. The clamp according to the invention is easy to handle. The adjustment of the level of the furs can be done easily because it is possible with one hand to exert pressure on the curved portion of the second piece while firmly holding the first piece to feast the position of the rod in the clamp. These two parts can be produced by cutting, bending and deformation of an inexpensive sheet metal. In addition, when the non-return flexible lug relaxes after passing through a slot in the first piece, an audible signal is produced which serves as a witness to simply check that the assembly of the second piece in the first piece is well done. It is also possible without departing from the scope of the invention or the flexible non-return tabs at the end of the front portion of the second part for a bearing against the outer face of the upright 9 of the first part.
