Description

La présente invention concerne les ancrages à disques utilisés pour fixer dans le sol divers ouvrages tels que des palissages de vignoble, de houblonnière ou de verger, des clôtures, des haubans pour mâts, antennes, poteaux etc...The present invention relates to disc anchors used to fix various structures in the ground such as vineyard, hop or orchard trellises, fences, guy lines for masts, antennas, poles, etc.

De tels ouvrages sont essentiellement constitués d'un disque formé en hélice susceptible de coulisser sur une tige dont au moins une des extrémités est conformée en boucle ou en oeillet.Such works essentially consist of a helically formed disc capable of sliding on a rod, at least one of the ends of which is in the form of a loop or an eyelet.

Le disque d'égale épaisseur sur toute sa surface comporte une ouverture ou découpe sensiblement centrée sur son axe pour l'adaptation sur un outil de pose (généralement appelé clé). De part et d'autre de cette ouverture se trouvent des rainures pour des doigts d'entraînement également prévus sur la clé.The disc of equal thickness over its entire surface has an opening or cut substantially centered on its axis for adaptation on a setting tool (generally called a wrench). On either side of this opening are grooves for drive fingers also provided on the key.

La clé est essentiellement constituée d'un tube de large diamètre raccordé en T à une barre de préhension et portant à son extrémité une pointe associée à des doigts d'entraînement. Pour la pose de l'ancrage la tige est enfilée à l'intérieur du tube et le disque est calé sur les doigts d'entraînement à l'extrémité du tube de part et d'autre de la pointe.The key essentially consists of a large diameter tube connected in T to a gripping bar and carrying at its end a point associated with drive fingers. For the installation of the anchor the rod is threaded inside the tube and the disc is wedged on the drive fingers at the end of the tube on either side of the tip.

La clé assure ainsi l'entraînement du disque en hélice autour de son axe ce qui permet de le faire pénétrer profondément dans le sol avec la tige qui lui est associée. Une fois la bonne profondeur atteinte, la clé est retirée et l'extrémité dépassante et conformée en oeillet ou crochet de la tige reçoit le câble d'attache adéquat. Le disque s'oppose alors à l'arrachement de la tige hors du sol sous l'effet des forces de tractions exercées sur cette dernière.The key thus drives the disc in a helix around its axis, which allows it to penetrate deep into the ground with the rod associated with it. Once the correct depth has been reached, the key is removed and the protruding end shaped as an eyelet or hook on the rod receives the appropriate attachment cable. The disc then opposes the tearing of the rod out of the ground under the effect of the traction forces exerted on the latter.

Avec les dispositifs actuellement connus, du fait que la tige est enfilée à l'intérieur du tube de la clé, l'encombrement de cette dernière est important car elle doit non seulement loger la tige mais aussi son extrémité conformée en oeillet ; elle doit également recevoir à son extrémité non seulement la pointe d'enfoncement mais les doigts d'entraînement ; en outre elle doit ménager un passage suffisant pour insérer la tige et sa boucle dans le tube de la clé. A cet effet la pointe est rainurée longitudinalement pour présenter une section globalement en C.With currently known devices, the fact that the rod is threaded inside the tube of the key, the size of the latter is important because it must not only house the rod but also its end shaped as an eyelet; it must also receive at its end not only the driving point but the drive fingers; in addition it must provide sufficient passage to insert the rod and its loop in the key tube. For this purpose the tip is grooved longitudinally to present a generally C-shaped section.

Un dispositif de ce type connu est représenté sur les figures 1a et 1b.ans un tel dispositif, l'outil est de réalisation compexe et coûteuse, il est volumineux et lourd et son encombrement oblige à déployer des forces très importantes pour enfoncer le disque dans le sol.A device of this known type is shown in FIGS. 1a and 1b. In such a device, the tool is of complex and expensive construction, it is bulky and heavy and its bulk requires the use of very large forces to drive the disc into floor.

De ce fait la pointe, fragilisée par sa découpe en C se déforme, et même se brise fréquemment, ce qui oblige à changer la clé car celle-ci est difficilement réparable en raison notamment de la forme des doigts d'entraînement.Therefore the tip, weakened by its cut in C is deformed, and even breaks frequently, which requires changing the key because it is difficult to repair due in particular to the shape of the drive fingers.

De plus la préparation de la pose est peu pratique puisqu'il faut retourner la clé pour enfiler la tige et positionner le disque sur la pointe de l'outil et maintenir l'ensemble pour planter la pointe dans le sol jusqu'à ce que le disque repose sur celui-ci, pour éviter qu'il ne se désengage de la clé.In addition, preparation for installation is impractical since the key must be turned over to thread the rod and position the disc on the tip of the tool and hold the assembly to plant the tip in the ground until the disc rests on it, to prevent it from disengaging from the key.

En outre, la tige étant sensiblement décentrée sur le disque pour laisser le passage à la pointe de l'outil, le disque a tendance à prendre dans le sol une position oblique sous l'effet des forces de traction ce qui nuit à sa résistance a l'arrachement.In addition, the rod being substantially off-center on the disc to allow passage at the tip of the tool, the disc tends to take an oblique position in the ground under the effect of the traction forces which affects its resistance to tearing.

De plus, du fait de la forme complexe des découpes du disque et de la pointe de l'outil, le disque n'a qu'une seule position convenable sur 360° dans laquelle il peut venir s'adapter correctement sur l'outil. L'utilisateur est donc obligé de manoeuvrer le disque pour le présenter à l'outil, ce qui complique encore le processus de pose.In addition, due to the complex shape of the disc cutouts and the tip of the tool, the disc has only one only suitable position on 360 ° in which it can come to fit correctly on the tool. The user is therefore obliged to maneuver the disk in order to present it to the tool, which further complicates the installation process.

Enfin, le disque doit nécessairement être maintenu perpendiculaire à l'axe longitudinal de la tige pour éviter qu'il ne se mette en biais en cours de pose ce qui aurait pour effet d'augmenter considérablement les efforts nécessaires à la pose voire même la rendre impossible.Finally, the disc must necessarily be kept perpendicular to the longitudinal axis of the rod to prevent it from skewing during installation, which would have the effect of considerably increasing the forces necessary for installation or even rendering it impossible.

Dans les dispositifs connus, ce guidage ou maintien, est obtenu par la complexité des formes de la pointe de l'outil et des découpes concordantes du disque.In known devices, this guidance or maintenance is obtained by the complexity of the shapes of the tip of the tool and the concordant cuts of the disc.

La présente invention a pour but de proposer un nouveau dispositif d'ancrage à disque qui ne présente pas ces inconvénients et qui assure par des moyens simples et peu coûteux une mise en place précise, rapide et aisée de l'ancrage, ainsi qu'une position horizontale du disque dans le sol.The object of the present invention is to propose a new disc anchoring device which does not have these drawbacks and which ensures by simple and inexpensive means a precise, rapid and easy installation of the anchoring, as well as a horizontal position of the disc in the ground.

A cet effet l'invention propose un nouvel ensemble d'ancrage à disque, constitué d'un disque en hélice associé à une tige dont l'extrémité hors sol est conformée en boucle ou en oeillet et d'une clé de pose en forme générale de T possédant un fût vertical plein ou creux caractérisé en ce que le disque comporte, outre l'ouverture de passage de la tige, une unique ouverture d'entraînement et de guidage présentant au moins un angle vif associé à au moins un moyen de guidage venu de matière et en ce que le fût de la clé comporte une extrémité pleine et pointue se raccordant à une portion de forme concordante à celle de l'ouverture du disque qui assure ainsi à la fois le guidage et l'entraînement du disque par la clé.To this end, the invention proposes a new disc anchoring assembly, consisting of a helical disc associated with a rod, the above-ground end of which is in the form of a loop or an eyelet and a key for laying in general shape. of T having a full or hollow vertical barrel characterized in that the disc comprises, in addition to the opening for passage of the rod, a single drive and guide opening having at least one sharp angle associated with at least one guide means made of material and in that the barrel of the key has a solid and pointed end connecting to a portion of shape corresponding to that of the opening of the disc which thus ensures both the guidance and the drive of the disc by the key.

Selon l'invention, du fait de cette constitution particulière de la clé et du disque, la tige du disque n'est plus enfilée à l'intérieur du fût de la clé pour la pose mais est disposée à l'extérieur et parallèlement à celui-ci, ce qui permet de simplifier considérablement la fabrication de la clé et de la rendre beaucoup moins encombrante.According to the invention, due to this particular constitution of the key and of the disc, the rod of the disc is no longer threaded inside the barrel of the key for installation but is arranged outside and parallel to that this, which considerably simplifies the manufacture of the key and makes it much less bulky.

Selon un mode de réalisation préféré l'ouverture de guidage et d'entraînement du disque est un rectangle obtenu par une découpe en croix formant trois triangles de matière rabattus à angles droits d'un côté et/ou de l'autre du bord de la découpe.According to a preferred embodiment the opening for guiding and driving the disc is a rectangle obtained by a cross cut forming three triangles of material folded down at right angles on one side and / or the other of the edge of the cutting.

D'autres dispositions de la présente invention apparaîtront au cours de la description qui va suivre d'un exemple de réalisation de l'ensemble, suivant la présente invention, en référence au dessin annexé dans lequel :

  • - la figure 2 est une vue en plan du disque d'ancrage, selon l'invention, en cours de fabrication.
  • - la figure 3 est une vue de la clé selon l'invention.
  • - la figure 4 est une vue à plus grande échelle de l'extrémité de la clé
  • - la figure 5 est une vue du disque d'ancrage positionné sur l'outil
  • - la figure 6 est une vue partielle de l'extréminté de la tige.
Other provisions of the present invention will appear during the description which follows of an embodiment of the assembly, according to the present invention, with reference to the appended drawing in which:
  • - Figure 2 is a plan view of the anchor disc, according to the invention, during manufacture.
  • - Figure 3 is a view of the key according to the invention.
  • - Figure 4 is an enlarged view of the end of the key
  • - Figure 5 is a view of the anchor disc positioned on the tool
  • - Figure 6 is a partial view of the end of the rod.

La figure 2 montre le disque d'ancrage 1 selon l'invention. Sur cette figure, la mise en forme du disque 1 n'est pas terminée ; il est encore à plat.Figure 2 shows the anchor disc 1 according to the invention. In this figure, the shaping of the disc 1 is not finished; it is still flat.

On voit en 12 l'ouverture destinée au passage de la tige 2 qui doit être ancrée dans le sol au moyen de ce disque. L'extrémité de ladite tige 2 destinée à être positionnée sous le disque est élargie de manière connue en soi.We see at 12 the opening intended for the passage of the rod 2 which must be anchored in the ground by means of this disc. The end of said rod 2 intended to be positioned under the disc is widened in a manner known per se.

Une découpe 13 est visible à la surface du disque 1, cette découpe est globalement en forme de croix et définit ainsi des points a,b,c,d disposés afin de former, dans l'exemple représenté, un rectangle. Trois des triangles définis par cette découpe 13 en croix ont été conservés tandis que le dernier fait partie de ladite découpe. Une fente radiale 14 relie la découpe 13 à la périphérie du disque 1. Comme visible à la figure 2, cette fente 14 débouche dans la découpe 13 dans la partie triangulaire de celle-ci.A cutout 13 is visible on the surface of the disc 1, this cutout is generally in the shape of a cross and thus defines points a, b, c, d arranged in order to form, in the example shown, a rectangle. Three of the triangles defined by this cross-cut 13 have been kept while the last is part of said cut. A radial slot 14 connects the cutout 13 to the periphery of the disc 1. As can be seen in FIG. 2, this slot 14 opens into the cutout 13 in the triangular part thereof.

En variante, la découpe 13 pourrait être suivant une croix laissant tout autour d'elle les triangles de métal qu'elle délimite, la fente 14 s'étendrait alors jusqu'au centre de la croix et découperait alors un desdits triangles en deux parties. La fente est destinée à permettre la déformation du disque 1 afin de le conformer en hélice.Alternatively, the cutout 13 could be in a cross leaving all around it the metal triangles that it delimits, the slot 14 would then extend to the center of the cross and would then cut one of said triangles into two parts. The slot is intended to allow the deformation of the disc 1 in order to conform it into a helix.

Ce faisant, les bords radiaux de la fente 14 seront écartés du plan initial du disque vers le haut et vers le bas.In doing so, the radial edges of the slot 14 will be moved up and down from the initial plane of the disc.

Les segments aa′ et dd′ reliant les extrémités de la découpe 13 aux bords de la fente 14 à son débouché dans la découpe se trouvent après la mise en forme du disque 1 globalement parallèles l'un à l'autre en formant un angle avec leur direction initiale.The segments aa ′ and dd ′ connecting the ends of the cutout 13 to the edges of the slot 14 at its outlet in the cutout are found after the disc 1 has been shaped, generally parallel to each other at an angle with their initial direction.

Les parties triangulaires 15 de métal sont alors repliées suivant les côtés ab,bc,cd du rectangle défini par la découpe 13.The triangular parts 15 of metal are then folded along the sides ab, bc, cd of the rectangle defined by the cutout 13.

Lesdits triangles 15 sont rabattus d'un côté et/ou de l'autre du plan du disque afin d'être parallèles à l'axe de rotation de l'hélice formée par ledit disque après sa mise en forme.Said triangles 15 are folded down on one side and / or the other of the plane of the disc so as to be parallel to the axis of rotation of the propeller formed by said disc after its shaping.

On comprend que le disque 1, présente alors une ouverture rectangulaire 16, visible en pointillés à la figure 1, dont trois des bords sont bordés des rabats 15.It will be understood that the disc 1 then has a rectangular opening 16, visible in dotted lines in FIG. 1, three of the edges of which are bordered by the flaps 15.

Ces bords rabattus constituent de manière simple des moyens de maintien du disque dans sa position perpendiculaire au fût de la clé au cours de la pose.These folded edges simply constitute means for holding the disc in its position perpendicular to the barrel of the key during installation.

De manière préférée, et tel que représenté, l'un des côtés, ici le côté bc, de l'ouverture 16 passe sensiblement par le centre du disque 1.Preferably, and as shown, one of the sides, here the side bc, of the opening 16 passes substantially through the center of the disc 1.

Cette ouverture 16 est, comme on l'aura compris, destinée à permettre le passage et le guidage de l'outil de pose 3 représenté schématiquement à la figure 3.This opening 16 is, as will be understood, intended to allow the passage and the guidance of the positioning tool 3 shown diagrammatically in FIG. 3.

Cet outil est formé d'un fût 30 creux ou plein terminé à une extrémité par un embout perforant 31 et portant à l'autre extrémité une barre transversale 34 par laquelle on peut entraîner l'outil 3 en rotation autour de son axe longitudinal.This tool is formed by a hollow or full barrel 30 terminated at one end by a perforating end piece 31 and carrying at the other end a transverse bar 34 by which the tool 3 can be driven in rotation about its longitudinal axis.

L'embout perforant 31 comporte une pointe pleine 32 qui peut être en ogive et une portion 33 de section égale à l'ouverture 16 définie dans le disque 1.The perforating end piece 31 has a solid point 32 which may be in a warhead and a portion 33 of section equal to the opening 16 defined in the disc 1.

La figure 5 montre la disposition des différentes pièces les unes par rapport aux autres lorsque l'on désire procéder à la pose d'un ancrage ans le sol.FIG. 5 shows the arrangement of the different parts with respect to one another when it is desired to lay an anchor in the ground.

Le disque étant posé au sol à son point précis d'enfoncement, l'embout perforant 31 est inséré dans l'ouverture 16 et est guidé par les triangles 15 de matière ainsi que par les arêtes aa' et dd' afin d'être parallèle à l'axe de rotation du disque 1.The disc being placed on the ground at its precise point of insertion, the perforating tip 31 is inserted into the opening 16 and is guided by the triangles 15 of material as well as by the edges aa 'and dd' so as to be parallel to the axis of rotation of the disc 1.

Du fait de la régularité de forme de la découpe du disque et de l'extrémité de ce dernier l'outil se guide automatiquement dans sa position correcte par rapport au disque.Due to the regular shape of the cutting of the disc and of the end of the latter, the tool automatically guides itself into its correct position relative to the disc.

De plus en raison de sa symétrie parfaite de forme le disque peut s'enfoncer dans le sol qu'elle que soit celle de ses faces qui se trouve en appui sur le sol ; cela simplifie encore la pose puisque l'utilisateur n'a pas à prêter attention à la position d'une face particulière du disque lorsqu'il l'enfile sur sa tige.In addition, because of its perfect symmetry of shape, the disc can sink into the ground, whatever its faces, which rests on the ground; this further simplifies installation since the user does not have to pay attention to the position of a particular face of the disc when he puts it on his rod.

La tige 2 positionnée dans l'ouverture 12 du disque 1 est maintenue contre l'outil 3, dans cet exemple de réalisation, par des parois 35 de celui-ci agencées afin de créer des moyens de clipsage de ladite tige 2.The rod 2 positioned in the opening 12 of the disc 1 is held against the tool 3, in this embodiment, by walls 35 of the latter arranged so as to create means for clipping said rod 2.

En variante, la tige 2 du disque peut être positionnée le long du fût 30 de l'outil par tout autre moyen, par exemple un crochet basculant monté à rotation sur une poignée de l'outil et venant s'engager dans la boucle 20 de la tige 2.As a variant, the rod 2 of the disc can be positioned along the barrel 30 of the tool by any other means, for example a tilting hook rotatably mounted on a handle of the tool and engaging in the loop 20 of the rod 2.

L'outil 3 est ainsi positionné à travers le disque 1 en un point très proche du centre de rotation de celui-ci ce qui permet de réaliser de manière tout à fait convenable la mise en place du disque dans le sol.The tool 3 is thus positioned across the disc 1 at a point very close to the center of rotation of the latter, which makes it possible to carry out the fitting of the disc in the ground quite suitably.

Afin de faciliter la pénétration du disque dans le sol et surtout d'éviter des déformations de celui-ci dans le sens tendant à l'ouvrir lorsque le terrain est très dur, on peut prévoir, tel que représenté sur la figure 2, une nervure 17 semi-circulaire réalisée par emboutissage dont le centre est le centre de l'ouverture 16.In order to facilitate the penetration of the disc into the ground and above all to avoid deformations of the latter in the direction tending to open it when the ground is very hard, it is possible to provide, as shown in FIG. 2, a rib 17 semicircular produced by stamping, the center of which is the center of the opening 16.

La disposition de l'ouverture 16 de manière excentrée mais d'une très faible distance par rapport au disque présente de nombreux avantages :
- on peut ainsi prévoir l'ouverture 12 de passage de la tige 2 beaucoup plus près de l'axe du disque que dans les réalisations usuellement mises en oeuvre ce qui permet d'éviter des mises en biais du disque 1 dans le sol lors de fortes tractions sur l'extrémité de la tige.
- comme on le voit à la figure 5, le tige est positionnée à l'extérieur de l'outil 3 le long de celui-ci et non à l'intérieur. On réduit ainsi très notablement l'encombrement de ce que l'on entre dans le sol et ainsi la résistance de celui-ci. Il est alors possible de réduire en conséquence la dimension radiale de l'embout perforant 31 et du fût 30 qui le porte.The arrangement of the opening 16 eccentrically but at a very small distance from the disc has many advantages:
- It is thus possible to provide the opening 12 for passage of the rod 2 much closer to the axis of the disc than in the embodiments usually used, which makes it possible to avoid biasing of the disc 1 in the ground during strong pulls on the end of the stem.
- As seen in Figure 5, the rod is positioned outside of the tool 3 along it and not inside. This greatly reduces the size of what is entered into the ground and thus the resistance thereof. It is then possible to reduce the radial dimension of the perforating end piece 31 and of the barrel 30 which carries it accordingly.

D'autre part l'excentration de l'ouverture 16 est assez faible pour ne pas pertuber trop fortement la mise en place du disque.On the other hand the eccentricity of the opening 16 is small enough not to disturb the positioning of the disc too strongly.

La forme de l'ouverture 16 et la présence des triangles 15 rabattus afin de s'appliquer contre les faces de la portion 33 de l'embout perforant 31 assurent un positionnement parfait et très aisé du disque 1 sur l'outil 3. C'est pourqoi on peut utiliser celui-ci d'une manière tout-à-fait rapide, aisée et sans fatigue.The shape of the opening 16 and the presence of the triangles 15 folded down so as to be applied against the faces of the portion 33 of the perforating end piece 31 ensure perfect and very easy positioning of the disc 1 on the tool 3. C ' is why you can use it in a completely fast, easy and fatigue-free way.

En effet, lorsque l'on veut mettre en place un ancrage, il suffit de poser le disque 1 traversé par sa tige 2 sur le sol à l'endroit désiré. On tient alors la tige 2 verticalement et on insère l'embout perforant 31 de l'outil 3 tenu verticalement dans l'ouverture 16. On notera que l'utilisateur n'a pas de précaution particulière à prendre pour cette présentation, l'outil se guidant de lui-même en position correcte, comme expliqué plus haut. Les triangles rabattus 15 et les segments aa', dd' assurent le positionnement parfait et automatique du disque 1 sur l'outil. Il ne reste qu'à positionner la tige 2 dans les moyens de clipsage 35, de la maintenir et à se servir de la barre 34 pour entraîner l'outil 3 et donc le disque 1 en rotation.Indeed, when one wants to set up an anchor, simply place the disc 1 crossed by its rod 2 on the ground at the desired location. The rod 2 is then held vertically and the perforating end piece 31 of the tool 3 held vertically is inserted into the opening 16. note that the user has no particular precaution to take for this presentation, the tool guiding itself in the correct position, as explained above. The folded triangles 15 and the segments aa ', dd' ensure the perfect and automatic positioning of the disc 1 on the tool. It only remains to position the rod 2 in the clipping means 35, to maintain it and to use the bar 34 to drive the tool 3 and therefore the disc 1 in rotation.

'exemple décrit et représenté met en oeuvre une ouverture 16 rectangulaire, on comprend aisément que ladite ouverture pourra être de toute forme présentant des angles vifs afin qu'il soit possible d'assurer un entraînement en rotation du disque par la portion 33 de l'outil 3.'example described and shown implements a rectangular opening 16, it is easily understood that said opening may be of any shape having sharp angles so that it is possible to ensure a rotational drive of the disc by the portion 33 of the tool 3.

La portion 33 et l'ouverture 16 pourront bien entendu être triangulaires, carrés ou d'une toute autre forme géométrique présentant au moins un angle vif ou une autre indentation.The portion 33 and the opening 16 may of course be triangular, square or of any other geometric shape having at least one sharp angle or another indentation.

Dans le cours de la présente description on emploie le qualificatif de rectangulaire pour désigner la forme de découpe de guidage et d'entraînement du disque.In the course of the present description, the qualifier rectangular is used to designate the form of cutting for guiding and driving the disc.

Il s'agit de la forme de découpe du disque à plat ; une fois le disque mis en hélice la projection obtenue doit concorder à la forme en section de la portion d'extrémité du fût de la clé avec laquelle elle coopère ; dans les exemples représentés cette forme est de préférence une forme carrée.This is the cutting shape of the flat disc; once the disc has been placed in a helix, the projection obtained must match the sectional shape of the end portion of the barrel of the key with which it cooperates; in the examples shown, this shape is preferably a square shape.

La figure 6 montre une autre disposition particulièrement intéressante de l'invention.Figure 6 shows another particularly interesting arrangement of the invention.

Cette figure montre l'extrémité supérieure de latige 2 ; c'est à cette partie qu'est fixé le fil de fer 4 destiné à attacher le corps à ancrer.This figure shows the upper end of the rod 2; it is to this part that the wire 4 intended for attaching the body to be anchored is fixed.

Dans les dispositifs connus, cette extrémité est repliée en boucle soit fermée, soit ouverte. Lorsque l'on veut réaliser une boucle fermée, il est nécessaire de positionner tout d'abord le disque d'ancrage 1 sur la tige 2 puis de reprendre ladite tige pour fermer la boucle ce qui augmente notablement le temps de fabrication.In known devices, this end is folded back in a loop, either closed or open. When it is desired to produce a closed loop, it is necessary first of all to position the anchoring disc 1 on the rod 2 and then to take up the said rod to close the loop, which considerably increases the manufacturing time.

Une tige avec boucle ouverte est plus rapide à fabriquer mais pose un problème en utilisation car si la force de traction exercée par le fil est très importante, on peut arriver à déplier la boucle qui ne permet plus alors l'ancrage du fil.A rod with open loop is quicker to manufacture but poses a problem in use because if the tensile force exerted by the wire is very large, it is possible to unfold the loop which then no longer allows the anchoring of the wire.

La tige à boucle ouverte étant beaucoup plus pratique à utiliser car on peut alors monter le disque d'ancrage à tout moment, l'invention cherche à l'utiliser en prévoyant un perfectionnement permettant d'éviter tout risque d'ouverture.The open loop rod being much more practical to use because it is then possible to mount the anchoring disc at any time, the invention seeks to use it by providing an improvement making it possible to avoid any risk of opening.

A cet effet, l'extrémité de la tige est conformée en crochet 20 largement ouvert terminé par une portion 21 rectiligne faisant un angle 22 avec l'extrémité du crochet 20. Une telle disposition en crochet largement ouvert permet un montage très aisé du disque 1 sur la tige au moment où l'on veut mettre en oeuvre l'ancrage.To this end, the end of the rod is shaped as a widely open hook 20 terminated by a straight portion 21 making an angle 22 with the end of the hook 20. Such a widely open hook arrangement allows very easy mounting of the disc 1 on the rod when you want to use the anchor.

Il est alors possible de stocker les éléments séparément et donc dans un volume réduit.It is then possible to store the elements separately and therefore in a reduced volume.

Suivant l'invention, on prévoit une plaquette 23 allongée, par exemple rectangulaire, présentant une lumière 24 oblongue de dimension telle que l'on puissse positionner ladite plaquette 23 sur le crochet 20 tel que représenté à la figure.According to the invention, an elongated plate 23, for example rectangular, is provided, having an oblong slot 24 of dimension such that the said plate 23 can be positioned on the hook 20 as shown in the figure.

On voit qu'ainsi on évite tout risque d'ouverture du crochet 20 lorsque l'on applique une force de traction élevée sur le fil 4.It can be seen that this avoids any risk of opening of the hook 20 when a high tensile force is applied to the wire 4.

Dans la présente description on a utilisé un disque muni d'une tige amovible. Une telle disposition présente de gros anvantages pour le stockage. Mais on pourrait sans sortir du cadre de l'invention des disques sur lesquels la tige est soudée.In the present description, a disk is used provided with a removable rod. Such an arrangement has major advantages for storage. However, without departing from the scope of the invention, discs on which the rod is welded.
