Description

La présente invention se rapporte à un dispositif d'ancrage réglable permettant de relier ensemble un profilé métallique et une tige, notamment pour pouvoir adosser une paroi à un mur porteur.The present invention relates to an adjustable anchoring device for connecting together a metal profile and a rod, in particular to be able to lean against a wall to a load-bearing wall.

Un tel dispositif d'ancrage est notamment mis en oeuvre pour pouvoir isoler les habitations en insérant une couche de matériau isolant, par exemple de la laine de verre, entre la paroi et le mur porteur.Such an anchoring device is used in particular to insulate houses by inserting a layer of insulating material, for example glass wool, between the wall and the load-bearing wall.

Les profilés métalliques utilisés en pareille circonstance sont profilés en U et ils présentent deux ailes parallèles prolongées par une bordure libre, les deux bordures libres étant recourbées l'une vers l'autre. Ils sont alors installés verticalement de proche en proche à distance du mur porteur, et ils y sont maintenus en position fixe grâce à des appuis intermédiaires. Chaque appui intermédiaire comporte une tige filetée ancrée dans le mur porteur et un dispositif d'ancrage monté réglable sur la tige filetée pour pouvoir recevoir le profilé. La tige filetée s'étend sensiblement perpendiculairement au mur porteur, tandis que le dispositif d'ancrage solidaire du profilé est ajusté pour pouvoir le maintenir à la distance désirée du mur porteur. Une couche de laine de verre est alors étendue contre le mur porteur et, les parois sont ensuite appliquées puis vissées contre les profilés afin d'y être solidarisé de manière à emprisonner la laine de verre entre le mur porteur et les parois.The metal profiles used in such circumstances are U-shaped and they have two parallel wings extended by a free edge, the two free edges being curved towards each other. They are then installed vertically closer and closer to the load-bearing wall, and they are held in a fixed position by means of intermediate supports. Each intermediate support comprises a threaded rod anchored in the load-bearing wall and an adjustable mounting device on the threaded rod to receive the profile. The threaded rod extends substantially perpendicular to the load-bearing wall, while the anchoring device secured to the profile is adjusted to maintain it at the desired distance from the load-bearing wall. A layer of glass wool is then extended against the bearing wall and the walls are then applied and screwed against the profiles to be secured to trap the glass wool between the bearing wall and the walls.

Le dispositif d'ancrage comporte une partie de fixation présentant deux rainures opposées aptes à recevoir respectivement les bordures libres du profilé. Il comporte également une partie formant pince comprenant deux branches en berceau engagées l'une dans l'autre. Les branches présentent chacune deux extrémités opposées, une extrémité d'articulation et une extrémité libre de manoeuvre, ainsi qu'un mors situé entre les deux extrémités. L'une des branches présente un évidement qui s'étend entre le mors et l'extrémité libre de manoeuvre de manière à pouvoir engager l'autre branche. Ainsi, les deux extrémités d'articulation sont articulées l'une sur l'autre tandis que les mors sont rapprochés l'un de l'autre et les extrémités de manoeuvre écartées l'une de l'autre. En outre, un ressort hélicoïdal permet de maintenir ces extrémités de manoeuvre en position écartée l'une de l'autre. De la sorte, lorsque l'on vient rapprocher les extrémités libres de manoeuvre l'une de l'autre en comprimant le ressort hélicoïdal, les deux mors s'écartent l'un de l'autre et la tige filetée peut être engagée entre les deux. Lorsque l'on relâche les deux extrémités libres de manoeuvre, les deux bords viennent prendre en étau la tige filetée et le dispositif d'ancrage est alors solidaire de celle-ci. La partie de fixation est portée par l'une des branches et ainsi, la position relative du dispositif d'ancrage et partant, du profilé, peut être ajustée par rapport au mur porteur en agissant sur les extrémités libres de manoeuvre et en ajustant la position relative du dispositif d'ancrage par rapport à la tige filetée.The anchoring device comprises a fixing portion having two opposite grooves adapted respectively to receive the free edges of the profile. It also comprises a gripper portion comprising two cradle branches engaged one inside the other. The branches each have two opposite ends, a hinge end and a free maneuvering end, and a jaw located between the two ends. One of the branches has a recess extending between the jaw and the free end of maneuver so as to engage the other branch. Thus, the two hinge ends are hinged to one another while the jaws are close to one another and the maneuvering ends spaced apart from each other. In addition, a helical spring makes it possible to keep these operating ends in a position separated from each other. In this way, when it comes to bring the free ends of maneuver from each other by compressing the coil spring, the two jaws move away from each other and the threaded rod can be engaged between the two. When the two free maneuvering ends are released, the two edges engage the threaded rod in a vice and the anchoring device is then secured thereto. The attachment part is carried by one of the branches and thus, the relative position of the anchoring device and therefore the profile, can be adjusted relative to the carrier wall by acting on the free maneuvering ends and adjusting the position relative to the anchor device relative to the threaded rod.

Un tel dispositif d'ancrage est relativement coûteux à réaliser, puisqu'il est nécessaire de fabriquer deux branches différentes, puis de les monter l'une sur l'autre avec l'ajout d'un ressort hélicoïdal fait d'un fil en acier ressort. En outre, l'écartement des mors nécessite une amplitude significative de mouvement des extrémités libres de manoeuvre l'une vers l'autre.Such an anchoring device is relatively expensive to produce, since it is necessary to manufacture two different branches, and then to mount one on the other with the addition of a coil spring made of a steel wire spring. In addition, the spacing of the jaws requires a significant amplitude of movement of the free ends maneuver towards each other.

Aussi, un problème qui se pose et que vise à résoudre la présente invention est de fournir un dispositif d'ancrage réglable qui soit non seulement moins onéreux à réaliser, mais au surplus, qui soit plus simple à mettre en oeuvre.Also, a problem that arises and that aims to solve the present invention is to provide an adjustable anchoring device which is not only less expensive to achieve, but moreover, which is simpler to implement.

Dans ce but, la présente invention propose un dispositif d'ancrage réglable comportant des parties de fixation apte à venir en prise dans un profilé et une partie formant pince destinée à recevoir une tige, ladite partie formant pince comprenant, d'une part deux branches montées à pivotement l'une par rapport à l'autre autour d'une articulation, chacune desdites branches présentant un mors et une extrémité libre de manoeuvre espacée dudit mors, et d'autre part un organe de rappel élastiquement déformable destiné à maintenir les mors desdites branches rapprochés l'un de l'autre pour prendre en étau ladite tige, les extrémités de manoeuvre desdites branches étant aptes à être rapprochées l'une de l'autre pour écarter lesdits mors l'un de l'autre, tandis que ledit organe de rappel se déforme, de manière à pouvoir libérer ladite tige et régler la position relative de ladite partie formant pince et de ladite tige. Selon l'invention, ladite articulation est située entre lesdits mors et lesdites extrémités de manoeuvre desdites branches.For this purpose, the present invention provides an adjustable anchoring device comprising attachment portions adapted to engage a profile and a gripper portion for receiving a rod, said gripper portion comprising, on the one hand two limbs pivotally mounted relative to each other about a hinge, each of said branches having a jaw and a free maneuvering end spaced from said jaw, and secondly an elastically deformable return member for holding the jaws said branches close together to clamp said rod, the maneuvering ends of said branches being adapted to be brought closer to each other to separate said jaws from one another, while said return member is deformed, so as to release said rod and adjust the relative position of said clamp portion and said rod. According to the invention, said hinge is located between said jaws and said maneuvering ends of said branches.

Ainsi, une caractéristique de l'invention réside dans la réalisation d'un dispositif d'ancrage dans lequel l'articulation est située non pas à l'extrémité des branches mais entre les mors et les extrémités libres de manoeuvre, tandis que les branches s'étendent en partie parallèlement l'une par rapport à l'autre, de manière à obtenir une plus grande amplitude d'écartement des mors l'un par rapport à l'autre pour une moindre amplitude de rapprochement des extrémités libres de manoeuvre l'une de l'autre. De la sorte, le réglage du dispositif d'ancrage sur la tige est plus aisé.Thus, a feature of the invention lies in the production of an anchoring device in which the articulation is located not at the end of the branches but between the jaws and the free maneuvering ends, while the branches extend partly parallel to each other, so as to obtain a greater amplitude of separation of the jaws relative to each other for a smaller amplitude of approaching the free ends of maneuvering the one of the other. In this way, the adjustment of the anchoring device on the rod is easier.

En outre, selon une caractéristique de l'invention particulièrement avantageuse, ledit organe de rappel élastiquement déformable forme ladite articulation. De la sorte, le dispositif d'ancrage est plus simple à réaliser et partant, moins coûteux. Au surplus, lesdites branches et ledit organe de rappel sont moulés ensemble d'une seule pièce, par exemple par injection. De la sorte, le dispositif d'ancrage est encore moins coûteux à réaliser.In addition, according to a particularly advantageous feature of the invention, said elastically deformable return member forms said hinge. In this way, the anchoring device is simpler to produce and hence less expensive. In addition, said branches and said return member are molded together in one piece, for example by injection. In this way, the anchoring device is even less expensive to produce.

Selon une première variante de réalisation de l'invention particulièrement avantageuse, chacune desdites branches présente un bord libre de fixation opposé audit mors, les bords libres de fixation s'étendant sensiblement parallèlement entre eux à l'opposé l'un de l'autre par rapport auxdits mors pour pouvoir former lesdites parties de fixation. De la sorte, et ainsi qu'on l'expliquera plus en détail dans la suite de la description, les deux bordures libres des profilés sont aptes à venir s'appliquer respectivement contre les bords libres de fixation afin d'y appliquer deux forces opposées. Ainsi, un effort supplémentaire s'applique sur les deux mors entre lesquels la tige vient en prise.According to a first particularly advantageous embodiment of the invention, each of said branches has a free fixing edge opposite said jaw, the free fixing edges extending substantially parallel to each other opposite each other by relative to said jaws to form said fastening portions. In this way, and as will be explained in greater detail in the following description, the two free edges of the profiles are adapted to come respectively against the free fixing edges to apply two opposing forces . Thus, an additional effort is applied to the two jaws between which the rod engages.

Préférentiellement, chacun desdits bords libres de fixation présentent une gorge de fixation, les gorges de fixation étant orientées à l'opposé l'une de l'autre. Ainsi, les deux bordures libres du profilé orientées l'une vers l'autre sont adaptées à venir en prise respectivement à l'intérieur des gorges de manière à obtenir une meilleure solidarisation du dispositif d'ancrage et du profilé.Preferably, each of said free fixing edges have a fixing groove, the fixing grooves being oriented opposite to each other. Thus, the two free edges of the profile oriented toward each other are adapted to engage respectively inside the grooves so as to obtain a better attachment of the anchoring device and the profile.

Selon une caractéristique de réalisation particulièrement avantageuse, l'une desdites branches présente un retour s'étendant à l'opposé desdites extrémités de manoeuvre par rapport auxdits mors, et ladite une desdites branches présente deux bords libres de guidage opposés l'un de l'autre par rapport auxdits mors. De telles caractéristiques permettent un pré-positionnement du dispositif d'ancrage, dans lequel les deux extrémités libres de manoeuvre peuvent être entraînées l'une vers l'autre pour régler la position relative du dispositif d'ancrage et de la tige. Comme on l'expliquera ci-après, à partir de cette position, le dispositif d'ancrage est entraîné en rotation à l'intérieur du profilé d'environ un quart de tour de manière à porter respectivement les bords libres de fixation contre les bordures libres du profilé. Le dispositif d'ancrage est entraîné en rotation dans un plan sensiblement parallèles au plan moyen définit par le profilé et perpendiculaire à ladite tige. On obtient de la sorte le verrouillage du dispositif d'ancrage, en conservant la position relative du dispositif d'ancrage et de la tige selon la direction de la tige. Ainsi, la position du profilé par rapport au mur porteur demeure constante durant ce mouvement de verrouillage. De préférence, chacun desdits bords libres de guidage présente une gorge de guidage, les gorges de guidage étant orientées à l'opposé l'une de l'autre. De la sorte, le dispositif d'ancrage est parfaitement guidé lorsqu'il est entraîné en rotation d'un quart de tour, et au surplus les bordures libres du profilé ne quittent pas les gorges. De plus, lesdits bords libres de guidage s'étendent sensiblement perpendiculairement auxdits bords libres de fixation.According to a particularly advantageous embodiment, one of said branches has a return extending opposite said maneuvering ends with respect to said jaws, and said one of said branches has two free guide edges opposite one of the other by relative to said jaws. Such characteristics allow pre-positioning of the anchoring device, in which the two free maneuvering ends can be driven towards each other to adjust the relative position of the anchoring device and the rod. As will be explained below, from this position, the anchoring device is rotated inside the profile about a quarter of a turn so as to bear the free edges of fastening against the edges respectively. free of the profile. The anchoring device is rotated in a plane substantially parallel to the mean plane defined by the profile and perpendicular to said rod. In this way the locking of the anchoring device is obtained, keeping the relative position of the anchoring device and the rod in the direction of the rod. Thus, the position of the profile relative to the load-bearing wall remains constant during this locking movement. Preferably, each of said free guide edges has a guide groove, the guide grooves being oriented opposite one another. In this way, the anchoring device is perfectly guided when rotated by a quarter of a turn, and moreover the free edges of the profile do not leave the grooves. In addition, said free guiding edges extend substantially perpendicular to said free fixing edges.

En outre, ladite une desdites branches présente, avantageusement, des rampes de guidage qui s'étendent respectivement en saillie, selon une composante axiale, à partir desdits bords libres de guidage et en convergeant l'une vers l'autre. Ainsi, afin de venir engager les bordures libres du profilé contre les bords libres de guidage, on vient d'abord appliquer les rampes de guidage entre les bordures libres et on entraîne ensuite à force le dispositif d'ancrage à l'intérieur du profilé. Partant, les deux ailes parallèles du profilé tendent à s'écarter sous l'action des rampes de guidage, puis les bordures libres viennent en prise dans les bords libres de guidage.In addition, said one of said branches has, advantageously, guide ramps which extend respectively projecting, according to an axial component, from said free guiding edges and converging towards one another. Thus, in order to engage the free edges of the profile against the free guiding edges, the guide rails are first applied between the free edges and the anchoring device is then forced into the interior of the profile. Therefore, the two parallel wings of the profile tend to move away under the action of the guide rails, then the free edges engage in the free guiding edges.

Préférentiellement, selon un autre caractéristique de mises en oeuvre de l'invention particulièrement avantageuse, ladite une desdites branches présente une poignée d'entraînement étendue librement à l'opposé desdits mors. De la sorte, lors du pré-positionnement du dispositif d'ancrage dans le profilé, la poignée d'entraînement s'étend latéralement du profilé selon une direction inclinée par rapport à celui-ci. Pour entraîner le dispositif d'ancrage en rotation d'un quart de tour, on vient actionner la poignée d'entraînement d'un quart de tour et on vient ainsi verrouiller à la fois la tige et le dispositif d'ancrage par l'intermédiaire des mors et le dispositif d'ancrage et le profilé par l'intermédiaire des gorges de fixation des bords libres de fixation, et des bordures libres du profilé.Preferably, according to another feature of implementations of the invention particularly advantageous, said one of said branches has a drive handle extended freely opposite said jaws. In this way, during the pre-positioning of the anchoring device in the profile, the driving handle extends laterally of the profile in one direction. inclined with respect to it. To drive the anchoring device in rotation by a quarter of a turn, the drive handle is actuated a quarter of a turn and thus comes to lock both the rod and the anchoring device via jaws and the anchoring device and the profile through the fixing grooves of the free fastening edges, and free edges of the profile.

La Figure 1 illustre en perspective un dispositif d'ancrage 10 conforme à l'invention engagé à l'intérieur d'un profilé 12, lequel est représenté transparent pour une meilleure compréhension de la Figure, et une tige 14. La tige 14 présente des rainures circonstancielles. Le dispositif d'ancrage 10 est ici pré-positionné et il est apte à être verrouillé afin de maintenir en position fixe, la tige 14, le dispositif d'ancrage 10 et le profilé 12. On se rapportera tout d'abord aux Figures 3 à 7 afin de décrire en détail le dispositif d'ancrage avant de revenir aux Figures 1 à 2B, pour décrire son mode de mise en oeuvre.The Figure 1 illustrates in perspective an anchoring device 10 according to the invention engaged inside a profile 12, which is shown transparent for a better understanding of the Figure, and a rod 14. The rod 14 has circumferential grooves. The anchoring device 10 is here pre-positioned and it is adapted to be locked in order to maintain in fixed position, the rod 14, the anchoring device 10 and the profile 12. We will refer first to Figures 3 to 7 to describe in detail the anchoring device before returning to Figures 1 to 2B , to describe its mode of implementation.

On retrouve sur la Figure 3 le dispositif d'ancrage 10 en vue de face. Ils présentent deux branches 16, 18 reliées ensemble par une articulation 20. Les branches 16, 18 et l'articulation 20 sont faits d'une seule pièce dans un matériau plastique semi-rigide, et élastiquement déformable. De la sorte, la mobilité des branches 16, 18, l'une par rapport à l'autre est rendue possible par la déformation élastique de l'articulation 20. Cette dernière est formée d'une partie hémicylindrique que l'on détaillera ci-après. Cette partie hémicylindrique est libre par rapport aux deux branches 16, 18.We find on the Figure 3 the anchoring device 10 in front view. They have two branches 16, 18 connected together by a hinge 20. The branches 16, 18 and the hinge 20 are made in one piece in a semi-rigid plastic material, and elastically deformable. In this way, the mobility of the limbs 16, 18, relative to each other is made possible by the elastic deformation of the joint 20. The latter is formed of a hemicylindrical part which will be detailed below. after. This hemi-cylindrical part is free with respect to the two branches 16, 18.

La première branche 16 présente un premier mors 22 tandis que la seconde branche 18, hachurée pour des besoins de clarté, présente un second mors 24. Les deux mors 22, 24 sont de forme hémicylindrique de révolution et ils s'étendent axialement en regard l'un de l'autre selon une direction perpendiculaire au plan de la Figure 3, de manière à former sensiblement ensemble, un espace cylindrique de révolution 26 et d'axe A. Au surplus, les deux mors 22, 24 définissent une paroi filetée d'un même filet d'hélice de manière à pouvoir recevoir en prise une tige filetée. Selon une caractéristique avantageuse de l'invention, non représentée, le même filet d'hélice présente non seulement une discontinuité au niveau de la jointure entre les deux mors 22, 24, mais également, une discontinuité au niveau de chacun des mors, de manière à faciliter la translation du dispositif d'ancrage 10 par rapport à la tige filetée. Ces dernières discontinuités sont par exemple formées en pratiquant des entailles dans les filets, selon une même direction axiale.The first branch 16 has a first jaw 22 while the second branch 18, hatched for clarity purposes, has a second jaw 24. The two jaws 22, 24 are hemi-cylindrical in shape and they extend axially facing the from one another in a direction perpendicular to the plane of the Figure 3 , so as to form substantially together a cylindrical space of revolution 26 and axis A. In addition, the two jaws 22, 24 define a threaded wall of the same helix thread so as to be able to receive a rod in engagement threaded. According to an advantageous characteristic of the invention, not shown, the same helical thread has not only a discontinuity at the joint between the two jaws 22, 24, but also a discontinuity at each of the jaws, so that to facilitate the translation of the anchoring device 10 relative to the threaded rod. These last discontinuities are for example formed by making notches in the threads, in the same axial direction.

On retrouve sur la Figure 6, les deux mors 22, 24 étendus axialement selon l'axe A, et l'articulation 20 étendue axialement sur une distance correspondant à une fraction de la longueur des mors 22, 24, et en l'espèce au voisinage de deux tiers de cette distance. L'épaisseur et la longueur de l'articulation de forme hémicylindrique conditionnent sa résistance à la déformation, et partant l'intensité des forces de retour élastique.We find on the Figure 6 , the two jaws 22, 24 extended axially along the axis A, and the articulation 20 extended axially over a distance corresponding to a fraction of the length of the jaws 22, 24, and in this case in the vicinity of two thirds of this distance. The thickness and length of the hemi-cylindrical hinge condition its resistance to deformation, and hence the intensity of elastic return forces.

Sur la Figure 3, la première branche 16 présente une première extrémité libre de manoeuvre 28, et la seconde 18, une seconde extrémité libre de manoeuvre 30, les deux extrémités libres de manoeuvre 28, 30 étant espacées l'une de l'autre de manière à pouvoir être rapprochées l'une vers l'autre comme on l'expliquera ci-après. En outre, la seconde branche 18 présente un bord frontal 31, opposé à la seconde extrémité libre de manoeuvre 30. Aussi, la seconde branche 18 est, dans sa position de repos telle qu'illustrée sur la Figure 3, reliée à la première branche 16 par la seule articulation 20.On the Figure 3 , the first branch 16 has a first free operating end 28, and the second 18, a second free operating end 30, the two free operating ends 28, 30 being spaced apart each other so that they can be brought closer to one another as will be explained below. In addition, the second branch 18 has a front edge 31, opposite the second free maneuvering end 30. Also, the second branch 18 is, in its rest position as shown in FIG. Figure 3 connected to the first branch 16 by the single hinge 20.

La première branche 16 présente un premier bord libre de fixation 32 opposé au premier mors 22, et la seconde branche 18 présente elle, un second bord libre de fixation 34 opposé au second mors 24. Les deux bords libres de fixation 32, 34 sont alors opposés l'un de l'autre par rapport aux mors 22, 24 et à l'espace cylindrique libre de révolution 26.The first branch 16 has a first free fastening edge 32 opposite the first jaw 22, and the second branch 18 has it, a second free fastening edge 34 opposite the second jaw 24. The two free fixing edges 32, 34 are then opposed to each other with respect to the jaws 22, 24 and to the free cylindrical space of revolution 26.

La Figure 4 présente une première tranche 36 du premier bord libre de fixation 32 du dispositif d'ancrage 10, tandis que la Figure 7 présente une seconde tranche 38, opposée, du second bord libre de fixation 34. Ainsi, sur la Figure 4 apparaît une première gorge de fixation 40 ménagée dans la première tranche 36 et qui s'étend sensiblement parallèlement au premier bord libre de fixation 32 sur un segment d'une distance sensiblement égale au diamètre de l'espace cylindrique de révolution 26. À l'opposé, sur la Figure 7, apparaît une seconde gorge de fixation 42 ménagée dans la seconde tranche 38, et s'étendant parallèlement au second bord libre de fixation 34, sur un segment d'une longueur sensiblement égale. La seconde gorge de fixation 42 est ouverte à l'opposé de la première gorge de fixation 40 et elle s'étend sur une distance correspondant également sensiblement au diamètre de l'espace cylindrique de révolution 26. En outre, les deux fonds de gorge de fixation 40, 42 s'étendent l'un de l'autre d'une distance D représentée sur la Figure 3.The Figure 4 has a first edge 36 of the first free fastening edge 32 of the anchoring device 10, while the Figure 7 has a second slice 38, opposite, of the second free fastening edge 34. Thus, on the Figure 4 a first fixing groove 40 formed in the first wafer 36 and extending substantially parallel to the first free fastening edge 32 on a segment of a distance substantially equal to the diameter of the cylindrical space of revolution 26. opposite, on the Figure 7 , there appears a second fixing groove 42 formed in the second wafer 38, and extending parallel to the second free fastening edge 34, on a segment of a substantially equal length. The second fixing groove 42 is open opposite the first fixing groove 40 and extends over a distance corresponding also substantially to the diameter of the cylindrical space of revolution 26. In addition, the two throat bottoms 40, 42 extend from one another by a distance D shown on the Figure 3 .

La Figure 3, illustre également dans le prolongement de la première branche 16, à l'opposé de la première extrémité libre de manoeuvre 28, un retour 44 venant s'étendre en regard du bord frontal 31 de la seconde branche 18 et présentant une extrémité libre 48 qui vient s'étendre elle, dans le prolongement du second bord libre de fixation 34. Ce retour 44 présente un premier bord libre de guidage 50 sensiblement perpendiculaire aux deux bords libres de fixation 32, 34.The Figure 3 , also illustrates in the extension of the first branch 16, opposite the first free operating end 28, a return 44 extending facing the front edge 31 of the second leg 18 and having a free end 48 which extends it, in the extension of the second free fastening edge 34. This return 44 has a first free guiding edge 50 substantially perpendicular to the two free fixing edges 32, 34.

Entre le premier bord libre de guidage 50 et le premier bord libre de fixation 32, et à l'opposé des deux mors 22, 24 et de l'espace cylindrique 26 qu'ils définissent, s'étend librement une poignée d'entraînement 52. La poignée d'entraînement 52 est inclinée d'environ 135° par rapport aux deux bords libres 32, 50 et elle s'étend sur une distance sensiblement équivalente à la distance D qui sépare les deux fonds de gorges de fixation 40, 42.Between the first free guide edge 50 and the first free fastening edge 32, and opposite the two jaws 22, 24 and the cylindrical space 26 they define, freely extends a drive handle 52. The drive handle 52 is inclined by about 135 ° with respect to the two free edges 32, 50 and extends over a distance substantially equivalent to the distance D which separates the two bottoms of fixing grooves 40, 42.

On expliquera plus en détail dans la suite de la description la fonction de la poignée d'entraînement 52. On observera toutefois sur les Figures 4 et 7 que les fonds de gorges de fixation 40, 42 qui définissent un plan de gorge G et la poignée d'entraînement 52 qui s'étend dans le plan moyen P défini par le dispositif d'ancrage 10, sont décalés l'un par rapport à l'autre selon l'axe de symétrie A défini par les deux mors 22, 24 hémicylindriques.The function of the driving handle 52 will be explained in greater detail in the remainder of the description. Figures 4 and 7 that the bottoms of the fixing grooves 40, 42 which define a groove plane G and the drive handle 52 which extends in the mean plane P defined by the anchoring device 10, are offset relative to the other along the axis of symmetry A defined by the two jaws 22, 24 hemicylindrical.

En outre, à l'opposé du premier bord libre de guidage par rapport à l'espace cylindrique 26, la première branche 16 présente un premier second bord libre de guidage 54 et la seconde branche 18 présente un second second bord libre de guidage 56, dans le prolongement du premier. Les deux seconds bords libres de guidage, 54, 56, sont alignés et ils s'étendent sensiblement à la même distance de l'espace cylindrique de révolution 26, que le premier bord libre de guidage 50. En outre, les deux seconds bords libres de guidage, 54, 56, sont sensiblement parallèles au premier bord libre de guidage 50.In addition, opposite the first free guide edge with respect to the cylindrical space 26, the first branch 16 has a first second free guide edge 54 and the second branch 18 has a second second free guide edge 56, in the extension of the first. The two second free guide edges 54, 56 are aligned and extend substantially the same distance from the cylindrical space of revolution 26 as the first free guide edge 50. In addition, the two second free edges 54, 56, are substantially parallel to the first free guiding edge 50.

Le premier bord libre de guidage 50 représenté sur la Figure 4 présente une première gorge de guidage 58, tandis que le second bord libre de guidage 54, 56 définissent une seconde gorge de guidage 60 opposée. Les première et seconde gorges de guidage 58, 60 sont également coupées dans le fond par le plan de gorge G. En outre, la distance d qui sépare les deux fonds de gorge de guidage 58, 60 est sensiblement inférieur à la distance D qui sépare les deux fonds de gorge de fixation 40, 42.The first free guiding edge 50 shown on the Figure 4 has a first guide groove 58, while the second free guide edge 54, 56 define a second opposite guide groove 60. The first and second guide grooves 58, 60 are also cut in the bottom by the groove plane G. In addition, the distance d between the two grooves 58, 60 is significantly smaller than the distance D which separates the two fixing grooves 40, 42.

Toutefois, on observera que le fond de la seconde gorge de guidage 60, au niveau du second second bord libre de guidage 56 est sensiblement plus profond qu'au niveau du premier second bord libre de guidage 54. On expliquera ci-après les avantages de cette différence.However, it will be observed that the bottom of the second guide groove 60, at the second second free guiding edge 56 is substantially deeper than at the first second free guiding edge 54. The advantages of this difference.

Ainsi, les segments de gorges de fixation 40, 42 et les segments de gorges de guidage 58, 60 définissent ensemble par leur fond de gorge et autour de l'espace cylindrique de révolution 26, une forme sensiblement rectangulaire. On observera que les gorges de fixation 40, 42 sont sensiblement rectilignes, et que les extrémités des gorges de guidage 58, 60 sont respectivement courbées vers les gorges de fixation 40, 42. Notamment, d'une part la seconde gorge de guidage 60 au niveau du second second bord libre de guidage 56, présente une première extrémité arrondie 62 et courbée vers la seconde gorge de fixation 42, et d'autre part, diamétralement opposée par rapport à l'espace cylindrique de révolution 26, la première gorge de guidage 58 présente une deuxième extrémité arrondie 64 et courbée vers la première gorge de fixation 40.Thus, the grooves segments 40, 42 and guide groove segments 58, 60 together define by their groove bottom and around the cylindrical space of revolution 26, a substantially rectangular shape. It will be observed that the fixing grooves 40, 42 are substantially rectilinear, and that the ends of the guide grooves 58, 60 are respectively curved towards the fixing grooves 40, 42. In particular, firstly the second guide groove 60 at the second second free guide edge 56, present a first rounded end 62 and curved towards the second fixing groove 42, and secondly, diametrically opposite to the cylindrical space of revolution 26, the first guide groove 58 has a second rounded end 64 and bent towards the first fixing groove 40.

Ainsi qu'on l'expliquera ci-après, les extrémités arrondies 62, 64 permettent de faciliter le mouvement du dispositif d'ancrage par rapport au profilé 12.As will be explained below, the rounded ends 62, 64 make it possible to facilitate the movement of the anchoring device with respect to the profile 12.

En outre, les branches 16, 18 sont équipées de moyens de verrouillage pour les maintenir en position fixe lorsqu'elles sont maintenues rapprochées l'une de l'autre. On se référera à la Figure 4, puis aux Figures 3 et 5 pour définir ces moyens de verrouillage. Sur la Figure 4, les mors 22, 24 présentent deux extrémités opposées, une extrémité interne 66 et une extrémité externe 68. Au niveau de l'extrémité interne 66 représentée sur la Figure 3, l'un des mors 24 présente un ergot 70 qui s'étend en saillie de la tranche de la forme hémicylindrique vers la tranche de l'autre mors 22 et en regard d'un logement 72 correspondant à la forme de l'ergot 70. Ainsi, lorsque les deux mors 22, 24 sont rapprochés l'un de l'autre, l'ergot 70 vient se loger à l'intérieur du logement 72.In addition, the branches 16, 18 are equipped with locking means to hold them in a fixed position when they are kept close to one another. We will refer to the Figure 4 , then to Figures 3 and 5 to define these locking means. On the Figure 4 the jaws 22, 24 have two opposite ends, an inner end 66 and an outer end 68. At the inner end 66 shown in FIG. Figure 3 , one of the jaws 24 has a lug 70 which projects from the edge of the hemicylindrical shape to the edge of the other jaw 22 and opposite a housing 72 corresponding to the shape of the lug 70 Thus, when the two jaws 22, 24 are brought closer to each other, the lug 70 is housed inside the housing 72.

L'extrémité externe 68 des mors 22, 24, représentée sur les Figures 4 et 5, illustre des moyens de verrouillage externe. Ledit autre mors 22 présente un crochet 74 qui s'étend radialement à l'opposé de l'espace cylindrique de révolution 26 en définissant une première portée d'appui axial 76 et une portée d'appui radiale adjacente 78. En outre, ledit un des mors 24 présente une portion en U complémentaire 80 étendue en saillie et apte à venir en prise contre les portées d'appui axiale 76 et radiale 78 lorsque les deux mors 22, 24 sont rapprochés l'un de l'autre.The outer end 68 of the jaws 22, 24, shown in the Figures 4 and 5 , illustrates external locking means. Said other jaw 22 has a hook 74 which extends radially opposite the cylindrical space of revolution 26 by defining a first axial bearing surface 76 and an adjacent radial bearing surface 78. In addition, said one jaws 24 has a complementary U-shaped portion 80 extending projecting and adapted to engage against the axial bearing surfaces 76 and radial 78 when the two jaws 22, 24 are brought closer to one another.

Au surplus, selon un mode de mise en oeuvre de l'invention non représenté, d'une part la portion en U complémentaire 80 s'étend axialement jusqu'au niveau du plan moyen P défini par le dispositif d'ancrage 10, et elle présente un crochet d'arrêt apte à venir coopérer avec le crochet 74 de l'autre mors 22, et d'autre part, la première branche 16 présente une butée située au niveau du plan moyen P, en regard du crochet 74. De la sorte, lorsque le de mors 22, 24 se rapprochent l'un de l'autre, la portion en U vient en contact avec la butée qui provoque alors un mouvement axial et l'engagement du crochet d'arrêt avec le crochet 74 de l'autre mors 22. Les deux crochets sont alors verrouillés l'un dans l'autre.In addition, according to an embodiment of the invention not shown, on the one hand the complementary U-shaped portion 80 extends axially to the level of the average plane P defined by the anchoring device 10, and has a stop hook adapted to cooperate with the hook 74 of the other jaw 22, and secondly, the first leg 16 has a stop located at the average plane P, opposite the hook 74. so, when the jaw 22, 24 come closer to each other, the U-shaped portion comes into contact with the stop which then causes an axial movement and the engagement of the stop hook with the hook 74 of the Other jaws 22. The two hooks are then locked one inside the other.

Ainsi, lorsque les deux bords 22, 24 sont rapprochés l'un de l'autre, ils sont maintenus en position fixe l'un par rapport à l'autre au niveau de leurs deux extrémités opposées 66, 68.Thus, when the two edges 22, 24 are brought closer to each other, they are held in a fixed position relative to each other at their two opposite ends 66, 68.

Au surplus, au niveau de l'extrémité libre 48 de la première branche 16 illustrée sur la Figure 7, le bord frontal 31 de la seconde branche 18 présente, à l'opposé de la seconde gorge de fixation 42 par rapport au plan moyen P, une languette 82 qui s'étend en saillie. La languette 82 forme un second appui axial 84 contre laquelle vient prendre appui la bordure latérale de l'extrémité libre 48 lorsque cette dernière et le bord frontal 31 sont rapprochés l'un de l'autre. De la sorte, et ainsi qu'on l'expliquera ci-après, lorsque le dispositif d'ancrage est entraîné en mouvement à l'intérieur du profilé, le retour 44 de la première branche 16 et le bord frontal 31 de la seconde branche 18 sont solidaires l'un de l'autre.In addition, at the free end 48 of the first branch 16 illustrated on the Figure 7 , the front edge 31 of the second branch 18 has, opposite the second attachment groove 42 relative to the average plane P, a tongue 82 which projects. The tongue 82 forms a second axial support 84 against which bears the lateral edge of the free end 48 when the latter and the front edge 31 are brought closer to each other. In this way, and as will be explained below, when the anchoring device is driven in motion inside the profile, the return 44 of the first branch 16 and the front edge 31 of the second branch 18 are integral with each other.

Les Figures 3 et 4 montre en outre une première paire de rampes de guidage 86, 88 installée sur le retour 44, et à l'opposé par rapport à l'espace cylindrique de révolution 26 une seconde paire de rampe de guidage, une première seconde rampe 90, sur la première branche 16 et une seconde seconde rampe 92 sur la seconde branche 18. La première paire de rampes de guidage 86, 88 converge du premier bord libre de guidage vers l'axe de symétrie A, tandis qu'à l'opposé, la seconde paire de rampe de guidage 90, 92 converge respectivement des premier second bord libre de guidage 54 et second second bord libre de guidage 56 vers l'axe de symétrie A de l'espace cylindrique 26.The Figures 3 and 4 further shows a first pair of guide rails 86, 88 installed on the return 44, and opposite to the cylindrical space of revolution 26 a second pair of guide ramp, a first second ramp 90, on the first branch 16 and a second second ramp 92 on the second branch 18. The first pair of guide ramps 86, 88 converges from the first free guide edge to the axis of symmetry A, while on the opposite side, the second A pair of guide ramps 90, 92 respectively converge from the first second free guide edge 54 and the second second free guide edge 56 towards the axis of symmetry A of the cylindrical space 26.

Le dispositif d'ancrage réglable 10 conforme à l'invention est de préférence moulé d'une seule pièce en matière plastique, par exemple en polyamide, et le cas échéant chargée de fibre de verre. Un tel matériau chargé permet d'obtenir une bonne élasticité de l'articulation 20.The adjustable anchoring device 10 according to the invention is preferably molded in one piece of plastic material, for example in polyamide, and if necessary filled with fiberglass. Such a loaded material makes it possible to obtain a good elasticity of the joint 20.

Ainsi, le dispositif d'ancrage réglable conforme à l'invention est destiné à solidariser ensemble la tige 14 et le profilé 12. Aussi, la tige 14 est préalablement engagée entre les mors 22, 24. Lorsque le dispositif d'ancrage 10 est libre, la tige 14 fileté peut être vissé à l'intérieur de l'espace cylindrique 26. Elle peut également être portée plus rapidement entre les mors 22, 24 en venant rapprocher l'une de l'autre les extrémités libres de manoeuvre 28, 30, ce qui a pour effet de déformer l'articulation 20 élastiquement déformable et écarter l'un de l'autre les deux mors 22, 24. De la sorte, la tige 14 peut être engagée librement entre les mors 22, 24. Lorsque les extrémités libres de manoeuvre 28, 30 sont relâchées, les deux mors 22, 24 viennent en prise sur la tige 14. La tige 14 est alors engagée entre les deux branches 16, 18 de façon que son extrémité libre s'étende au voisinage de l'extrémité interne 66 des mors 22, 24.Thus, the adjustable anchoring device according to the invention is intended to secure together the rod 14 and the profile 12. Also, the rod 14 is previously engaged between the jaws 22, 24. When the anchoring device 10 is free , the threaded rod 14 can be screwed inside the cylindrical space 26. It can also be worn more quickly between the jaws 22, 24 coming to bring the free operating ends 28, 30 towards one another. , which has the effect of deforming the elastically deformable articulation 20 and move the two jaws 22, 24 apart from one another. In this way, the rod 14 can be freely engaged between the jaws 22, 24. free operating ends 28, 30 are released, the two jaws 22, 24 engage on the rod 14. The rod 14 is then engaged between the two branches 16, 18 so that its free end extends in the vicinity of the inner end 66 of the jaws 22, 24.

Ensuite, le dispositif d'ancrage 10 est engagé à l'intérieur du profilé 12. Tel que représenté sur la Figure 2B, le profilé 12 présente deux ailes opposées 94, 96 prolongées respectivement par deux bordures libres 98, 100 qui s'étendent en retour l'une vers l'autre. Ainsi, les deux bordures libres 98, 100 sont appliqués contre les deux paires de rampes de guidage 86, 88 ; 90, 92, puis le dispositif d'ancrage 10 et le profilé 12 sont entraînés à force l'un contre l'autre. Les deux bordures libres 98, 100 sont entraînées en frottement contre les deux paires de rampes de guidage 86, 88 ; 90, 92, tandis que les deux ailes opposées 94, 96 s'écartent élastiquement l'une de l'autre, jusqu'à ce qu'elles atteignent les premier et second bord libre de guidage 50, 54, 56, pour ensuite retomber dans les première et seconde gorges de guidage 58, 60. De la sorte, et tel que représenté sur la Figure 1, les deux bordures libres 98, 100 du profilé 12 enserrent le dispositif d'ancrage 10. Les deux extrémités libres de manoeuvre 28, 30 s'étendent alors latéralement d'un côté en dehors du profilé 12, tandis que la poignée d'entraînement 52 s'étend latéralement dans le côté opposé alors que la tige 14 s'étend sensiblement perpendiculairement au profilé 12.Then, the anchoring device 10 is engaged inside the profile 12. As shown in FIG. Figure 2B , the profile 12 has two opposite wings 94, 96 respectively extended by two free edges 98, 100 which extend back towards one another. Thus, the two free edges 98, 100 are applied against the two pairs of guide rails 86, 88; 90, 92, then the anchoring device 10 and the profile 12 are forced against each other. The two free edges 98, 100 are driven in friction against the two pairs of guide rails 86, 88; 90, 92, while the two opposite wings 94, 96 move elastically away from each other until they reach the first and second free guide edges 50, 54, 56, then fall back in the first and second guiding grooves 58, 60. In this way, and as shown in FIG. Figure 1 , the two free edges 98, 100 of the profile 12 enclose the anchoring device 10. The two free operating ends 28, 30 then extend laterally to one side outside the profile 12, while the drive handle 52 extends laterally in the opposite side while the rod 14 extends substantially perpendicularly to the profile 12.

Dans cette première phase d'installation, le réglage plus fin de la position relative de la tige 14 et du profilé 12 est réalisé en rapprochant l'une de l'autre manuellement les extrémités de manoeuvre 28, 30 de manière à écarter les mors 22, 24 l'un de l'autre et à libérer partiellement la tige 14. Cette manoeuvre est facilitée, car la seconde branche 18 est relativement libre par rapport au profilé, et notamment par rapport aux bordures libres 98, 100. En effet, l'une ou l'autre des bordures libres s'appuie sur le fond de la seconde gorge de guidage 60, au niveau du premier second bord libre de guidage 54 et non pas sur le fond de la seconde gorge de guidage 60 au niveau du second second bord libre 56 qui est plus profond. Aussi, la seconde branche 18 est relativement plus libre en rotation autour de l'articulation 20 dans le plan P. En outre, l'articulation 20 étant située entre les mors 22, 24 et les extrémités libres de manoeuvre 28, 30, tandis que les branches 16, 18 s'étendent en partie parallèlement, l'écartement sensible des mors 22, 24 est réalisé grâce a une faible amplitude de mouvement des extrémités libres de manoeuvre 28, 30 l'une vers l'autre.In this first phase of installation, the finer adjustment of the relative position of the rod 14 and the section 12 is made by moving the maneuvering ends 28, 30 towards each other manually so as to move the jaws 22 apart. 24, and to partially release the rod 14. This maneuver is facilitated because the second leg 18 is relatively free with respect to the profile, and in particular with respect to the free edges 98, 100. one or the other of the free edges rests on the bottom of the second guide groove 60, at the first second free guide edge 54 and not on the bottom of the second guide groove 60 at the second second free edge 56 which is deeper. Also, the second branch 18 is relatively free to rotate about the hinge 20 in the plane P. In addition, the hinge 20 is located between the jaws 22, 24 and the free ends of maneuvering 28, 30, while the branches 16, 18 extend in part parallel, the substantial spacing of the jaws 22, 24 is achieved by a small amplitude of movement of the free operating ends 28, 30 towards one another.

Après que la position relative de la tige 14 et du profilé 12 a été réglée, la poignée d'entraînement 52 est alors entraînée en mouvement à force le long du profilé 12 de manière à entraîner en rotation le dispositif d'ancrage 10 d'environ 90°. On obtient alors une position relative du dispositif d'ancrage 10 telle que représentée sur la Figure 2A. Les deux branches 16, 18 et les extrémités de manoeuvre correspondantes 28, 30 se retrouvent alors orientées sensiblement parallèlement aux profilés 12, tandis que la poignée d'entraînement 52 a été basculée de 90°. Lors du basculement, dans une première phase, les extrémités arrondies 62, 64 diamétralement opposées, respectivement des première et seconde gorges de guidage 58, 60 sont entraînées à force contre les bordures libres 98, 100. Les ailes 94, 96 du profilé 12 tendent alors à s'écarter sensiblement l'une de l'autre jusqu'à ce que la ligne coupant les deux extrémités arrondies 62, 64 viennent s'étendre sensiblement perpendiculairement au profilé 12. Les bordures libres 98, 100 en regard exercent alors une contrainte concentrique tendant à entraîner les deux branches 16, 18 l'une contre l'autre et partant, les deux mors 22, 24 l'un vers l'autre en enserrant plus encore la tige 14, d'une part, et la bordure latérale de l'extrémité libre 48 contre la languette 82 d'autre part. Ensuite, lorsque le basculement se poursuit dans une deuxième phase, le retour 44 de la première branche 16 est solidaire du bord frontal 31 de la seconde branche 18 et les bordures libres 98, 100 viennent respectivement s'appuyer respectivement dans le fond des gorges de fixation 40, 42. La tige 14 demeure alors enserrée entre les mors 22, 24, après le basculement complet, car la distance D qui s'étend entre les deux fonds de gorges de fixation 40, 42 est supérieure à la distance d qui sépare les deux fonds de gorges de guidage 58, 60. De la sorte, la tige 14 est prisonnière du dispositif d'ancrage 10 qui lui-même est prisonnier du profilé 12. L'ensemble est alors verrouillé.After the relative position of the rod 14 and the profile 12 has been adjusted, the driving handle 52 is then forced into movement along the profile 12 so as to rotate the anchoring device 10 by approximately 90 °. A relative position of the anchoring device 10 as shown in FIG. Figure 2A . The two branches 16, 18 and corresponding maneuvering ends 28, 30 are then oriented substantially parallel to the profiles 12, while the drive handle 52 has been tilted 90 °. During tilting, in a first phase, the diametrically opposite rounded ends 62, 64, respectively of the first and second guide grooves 58, 60 are force-driven against the free edges 98, 100. The flanges 94, 96 of the profile 12 tend to then to deviate significantly from each other until the line intersecting the two rounded ends 62, 64 are extended substantially perpendicularly to the profile 12. The free edges 98, 100 facing then exert a constraint concentric tending to drive the two branches 16, 18 against each other and therefore the two jaws 22, 24 towards each other further enclosing the rod 14, on the one hand, and the side edge of the free end 48 against the tongue 82 on the other hand. Then, when the tilting continues in a second phase, the return 44 of the first leg 16 is secured to the front edge 31 of the second leg 18 and the free edges 98, 100 respectively respectively bear in the bottom of the grooves of Fixing 40, 42. The rod 14 then remains sandwiched between the jaws 22, 24, after the complete tilting, because the distance D which extends between the two bottoms of fixing grooves 40, 42 is greater than the distance d which separates the two funds grooves guide 58, 60. In this way, the rod 14 is trapped in the anchoring device 10 which itself is trapped in the profile 12. The assembly is then locked.

On observera que l'entraînement de la poignée d'entraînement 52 dans un sens inverse est possible pour pouvoir réaliser un nouveau réglage de la position relative du profilé 12 par rapport à la tige 14.It will be observed that the driving of the driving handle 52 in a reverse direction is possible in order to be able to make a new adjustment of the relative position of the profile 12 with respect to the rod 14.

Par ailleurs, la tige 14, à son autre extrémité est ancrée dans un mur porteur. Cet ancrage peut être réalisé au moyen d'un autre profilé et d'un dispositif d'ancrage 10 analogue, ou bien tout autre dispositif d'ancrage non nécessairement réglable.Moreover, the rod 14, at its other end is anchored in a load-bearing wall. This anchoring can be achieved by means of another profile and a similar anchoring device 10, or any other anchoring device not necessarily adjustable.
