Abstract
Description
La présente invention a pour objet une cheville d'ancrage pour vis, pour pose en aveugle. The present invention relates to an anchor anchor for screws, for blind installation.
Plus précisément, cette cheville est du type comprenant un manchon de tète, ut manchon de queue coaxial au manchon de tète, des barrettes longitudinales reliant ces manchons, repliables et disposées autour de l'axe de ces derniers, le manchon de tête étant pourvu d'une collerette d'ancrage de la cheville dans une cloison et le manchon de queue étant taraudé pour coopérer avec une vis passant librement à travers le manchon de tête. More precisely, this ankle is of the type comprising a head sleeve, a tail sleeve coaxial with the head sleeve, longitudinal bars connecting these sleeves, foldable and arranged around the axis of the latter, the head sleeve being provided with 'An anchor flange of the ankle in a partition and the tail sleeve being tapped to cooperate with a screw passing freely through the head sleeve.
Une telle cheville est décrite par le brevet français 84 08 734 (N publication 2 546 989), et avantageusement réalisée d'une seule pièce de tôle. Such an anchor is described by French patent 84 08 734 (publication No. 2 546 989), and advantageously made from a single piece of sheet metal.
Comme on le sait, pour poser cette cheville, on fore au préalable un trou de passage dans la cloison creuse destinée à la recevoir, puis on enfonce la cheville à travers cette cloison jusqu'à ce que les pointes d'ancrage dont son manchon de tête est muni s'enfoncent dans la cloison et bloquent ainsi la cheville en rotation. Pour la fixer en place, il suffit alors, soit de visser la vis dans le manchon de queue jusqu'à ce que l'on rencontre une résistance indiquant que les barrettes se sont repliées en parapluie sur la face intérieure de la cloison creuse, soit d'exercer sur le manchon de queue une traction axiale au moyen d'une vis intégrée à un outil spécial, jusqu'8 ce que les barrettes viennent se replier sur la face intérieure de la cloison et fixent solidement en place la cheville. As we know, to install this dowel, we first drill a through hole in the hollow partition intended to receive it, then we push the dowel through this partition until the anchoring points including its sleeve head is fitted sink into the bulkhead and thus block the rotating dowel. To fix it in place, it is then enough either to screw the screw into the tail sleeve until a resistance is encountered indicating that the bars have folded up under an umbrella on the inside of the hollow partition, or to exert on the tail sleeve an axial traction by means of a screw integrated in a special tool, until the bars come to fold on the interior face of the partition and firmly fix the ankle.
Pour poser la cheville, il est donc nécessaire de disposer d'une perceuse. To install the anchor, it is therefore necessary to have a drill.
L'invention a pour but de proposer une cheville d'ancrage pour vis qui puisse être posée sans perceuse, grâce à des moyens incorporés à cette cheville. The object of the invention is to propose an anchor anchor for screws which can be laid without a drill, by means incorporated in this anchor.
Conformément à l'invention, la vis est prolongée par une pointe de guidage de la cheville à travers une cloison de support, et la cheville est munie de moyens de forage de ladite cloison après pénétration de la pointe dans cette dernière. According to the invention, the screw is extended by a point for guiding the dowel through a support partition, and the dowel is provided with means for drilling said partition after penetration of the point into the latter.
Suivant un mode de réalisation de l'invention, les moyens de forage comprennent au moins une dent coupante et de préférence deux diamétralement opposées, ménagées sur l'extrémité du manchon de queue opposée au manchon de tête. According to one embodiment of the invention, the drilling means comprise at least one cutting tooth and preferably two diametrically opposite, formed on the end of the tail sleeve opposite the head sleeve.
Pour poser la cheville selon l'invention, on enfonce d'abord sa pointe dans la cloison, ou le mur creux, par exemple au moyen d'un tournevis, puis on met l'ensemble de la cheville en rotation tout en maintenant la pression, afin de perforer la cloison après plusieurs tours, grâce aux dents tranchantes. En fin d'enfoncement de la cheville, les pointes de sa collerette d'ancrage viennent s'enfoncer dans la cloison et bloquer la cheville en rotation. To install the dowel according to the invention, first push its point into the partition, or the hollow wall, for example by means of a screwdriver, then put the whole dowel in rotation while maintaining the pressure , in order to perforate the partition after several turns, thanks to the sharp teeth. At the end of the insertion of the ankle, the points of its anchoring flange sink into the partition and block the ankle in rotation.
La pose de cette cheville-sur un support en matériau tendre, type plaque de plâtre par exemple, est donc particulièrement aisée et s'exécute sans perceuse. The installation of this dowel on a support made of soft material, for example plasterboard, is therefore particularly easy and is carried out without a drill.
D'autres particularités et avantages de l'invention apparaitront au cours de la description qui va suivre, faite en référence aux dessins annexés qui en illustrent une forme de réalisation à titre d'exemple non limitatif. Other features and advantages of the invention will become apparent during the description which follows, given with reference to the appended drawings which illustrate an embodiment thereof by way of nonlimiting example.
La figure 1 est une vue en perspective d'une forme de réalisation à échelle agrandie de la cheville d'ancrage selon l'invention. Figure 1 is a perspective view of an embodiment on an enlarged scale of the anchor pin according to the invention.
Les figures 2A à 2D sont des vues en élévation longitudinale illustrant une séquence de pose dans une cloison creuse, de la cheville d'ancrage de la Fig.1. FIGS. 2A to 2D are views in longitudinal elevation illustrating a sequence of installation in a hollow partition, of the anchor pin of FIG. 1.
La cheville 1 représentée aux dessins est destinée à assurer l'ancrage d'une vis, pour pose en aveugle, dans une cloison creuse 2 réalisée en un matériau tendre, tel que carton et plâtre des murs et cloisons du type plaque de plâtre. The plug 1 shown in the drawings is intended to anchor a screw, for blind installation, in a hollow partition 2 made of a soft material, such as cardboard and plaster for walls and partitions of the plasterboard type.
Cette cheville comprend un manchon de tète 3 et un manchon de queue 4 coaxiaux, d'axe XX, plusieurs barrettes longitudinales 5 reliant les manchons 3 et 4, repliables et disposées autour de l'axe commun de ces derniers. Le manchon de tête 3 est pourvu d'une collerette radiale 6 d'ancrage de la cheville dans la cloison 2, au moyen de pointes 7 découpées dans la périphérie de cette collerette. This anchor comprises a head sleeve 3 and a coaxial tail sleeve 4, of axis XX, several longitudinal bars 5 connecting the sleeves 3 and 4, foldable and arranged around the common axis of the latter. The head sleeve 3 is provided with a radial collar 6 for anchoring the ankle in the partition 2, by means of points 7 cut in the periphery of this collar.
Le manchon de queue 4 est taraudé pour pouvoir coopérer avec une vis 8 passant librement à travers le manchon de tête 3. The tail sleeve 4 is tapped to be able to cooperate with a screw 8 passing freely through the head sleeve 3.
La cheville 1 peut être réalisée d'une seule pièce en tôle, et fabriquée selon le procédé décrit au brevet français précité. Elle peut être également réalisée en deux ou trois parties fixées les unes aux autres. Ainsi les manchons 3 et 4 peuvent être rapportés aux extrémités des barrettes 5 par tout moyen approprié tel que soudage. The dowel 1 can be made in a single piece of sheet metal, and manufactured according to the method described in the aforementioned French patent. It can also be carried out in two or three parts fixed to each other. Thus the sleeves 3 and 4 can be attached to the ends of the bars 5 by any suitable means such as welding.
Le manchon de queue 4 comporte un collet intérieur 10 taraudé (Fig.2A) de réception de la vis 8, fixé à la partie extérieure dudit manchon par une liaison suffisamment solide pour que ce collet 10 ne puisse entre désolidarisé de cette partie extérieure par une poussée axiale exercée sur la vis 8 par un utilisateur lors de la pose de la cheville. The tail sleeve 4 has an internal threaded collar 10 (FIG. 2A) for receiving the screw 8, fixed to the external part of said sleeve by a sufficiently strong connection so that this collar 10 cannot be separated from this external part by a axial thrust exerted on the screw 8 by a user when fitting the dowel.
Cette liaison peut être, par exemple, constituée d'au moins une languette 12 profilée en T, venue de matière avec le collet 10 et insérée dans un dégagement correspondant du manchon de queue 4. This connection can be, for example, made up of at least one tongue 12 profiled in T, made integrally with the collar 10 and inserted in a corresponding clearance of the tail sleeve 4.
Si ce dernier est venu de matière avec le collet taraudé 10, la liaison est complétée du coté opposé à la languette 12 par un pontet (non visible aux dessins). If the latter came integrally with the threaded collar 10, the connection is completed on the side opposite to the tongue 12 by a trigger guard (not visible in the drawings).
La collerette 6 du manchon de tête 3 est reliée à ce dernier par des moyens permettant une séparation éventuelle de cette collerette du reste de la cheville 1 à l'aide d'un outil tel qu'un tournevis. The collar 6 of the head sleeve 3 is connected to the latter by means allowing possible separation of this collar from the rest of the pin 1 using a tool such as a screwdriver.
Cette séparation présente en effet un intérêt lorsqu'après une période d'utilisation de la cheville, on enlève l'objet accroché à la vis 8 et que l'on désire boucher le trou laissé après extraction de la vis sans laisser une trace visible (présence de la collerette 6 sur le mur).This separation is indeed of interest when after a period of use of the dowel, the object hung on the screw 8 is removed and it is desired to plug the hole left after extraction of the screw without leaving a visible trace ( presence of the collar 6 on the wall).
Ces moyens comprennent, dans l'exemple décrit, au moins une liaison en queue d'aronde 13 obtenue par une découpe t4 dans la collerette et rabattue dans une échancrure complémentaire du manchon de tête 3. De préférence deux queues d'aronde 13 diamétralement opposées sont ainsi découpées dans la collerette 6, ainsi que deux échancrures dans le manchon 3. En effet une telle liaison peut être facilement détruite à l'aide d'un outil quelconque. These means comprise, in the example described, at least one dovetail connection 13 obtained by a cut t4 in the flange and folded in a complementary notch of the head sleeve 3. Preferably two diametrically opposite dovetails 13 are thus cut in the collar 6, as well as two notches in the sleeve 3. In fact such a connection can be easily destroyed using any tool.
La vis 8, dont la tête 8a peut etre percée d'une entaille cruciforme, a sa tige 8b prolongée par une pointe 8c de guidage de la cheville à travers la cloison 2. La pointe ou pointeau 8c peut être venue de matière avec la vis 8, ou bien rapportée à celle-ci par soudage. The screw 8, the head 8a of which can be pierced with a cruciform notch, has its rod 8b extended by a point 8c for guiding the ankle through the partition 2. The point or needle 8c may have come in one piece with the screw 8, or related thereto by welding.
Complémentairement, la cheville est munie de moyens de forage de la cloison 2 après pénétration de la pointe 8c dans cette dernière. Dans l'exemple décrit, ces moyens de forage comprennent deux dents coupantes 9 ménagées sur l'extrémité du manchon de queue 4 opposée au manchon de tête 3, et diamétralement opposées (les manchons 3 et 4 étant cylindriques). Chaque dent 9 présente une arête tranchante 9a inclinée sur l'axe XX de la vis. Additionally, the plug is provided with means for drilling the partition 2 after penetration of the point 8c into the latter. In the example described, these drilling means comprise two cutting teeth 9 formed on the end of the tail sleeve 4 opposite to the head sleeve 3, and diametrically opposite (the sleeves 3 and 4 being cylindrical). Each tooth 9 has a cutting edge 9a inclined on the axis XX of the screw.
Lorsque la vis 8 est complètement enfoncée dans la cheville 1, l'extrémité filetée de sa tige 8b est engagée dans le taraudage correspondant du manchon de queue 4, et la pointe 8c fait saillie entre les dents 9, comme visible à la Fig.1. When the screw 8 is fully inserted into the dowel 1, the threaded end of its rod 8b is engaged in the corresponding tapping of the tail sleeve 4, and the tip 8c protrudes between the teeth 9, as visible in FIG. 1 .
La mise en oeuvre de la cheville qui vient d'être décrite se fait de la manière suivante. The implementation of the anchor which has just been described is done as follows.
On place la cheville 1 munie de sa vis pointeau 8 en face de l'emplacement à forer (Fig.2A). The dowel 1 with its needle screw 8 is placed opposite the location to be drilled (Fig.2A).
On applique la pointe 8c contre la cloison 2, à l'endroit précis où doit etre effectuée la pose, puis on introduit un tournevis 11 dans la tête 8a de la vis 8.The point 8c is applied against the partition 2, at the precise place where the installation is to be carried out, then a screwdriver 11 is introduced into the head 8a of the screw 8.
On pousse la cheville à l'aide du tournevis 11 jusqu'à pénétration complète de la pointe 8c de guidage dans la cloison 2 (Fig.2B). The dowel is pushed using the screwdriver 11 until the guide tip 8c has completely penetrated into the partition 2 (FIG. 2B).
On maintient légèrement la pression, tout en mettant manuellement l'ensemble en rotation (Flèche R sur la Fig.2B). La cloison 2 est perforée par les aretes tranchantes 9a après quatre ou cinq tours de la cheville 1 autour de son axe, et une dernière poussée axiale sur la cheville 1 a pour effet de plaquer la collerette de tete 6 contre la cloison 2 dans laquelle s'enfoncent les pointes 7 (Fig.2C). The pressure is slightly maintained, while manually putting the assembly in rotation (arrow R in FIG. 2B). The partition 2 is perforated by the sharp edges 9a after four or five turns of the dowel 1 around its axis, and a last axial thrust on the dowel 1 has the effect of pressing the head flange 6 against the partition 2 in which s 'push in the tips 7 (Fig.2C).
A ce moment, les barrettes 5 sont passées en entier du coté de la face intérieure de la cloison creuse 2, dont l'épaisseur correspond sensiblement à la longueur du manchon 3. On visse alors au moyen du tournevis 11 la vis 8, ce qui provoque l'expansion et le repliage des barrettes 5 en forme de parapluie sur la face intérieure de la cloison 2 (Fig.2D). La pose est terminée lorsque les barrettes 5 sont suffisamment repliées et exercent une pression convenable de fixation en place de la cheville. At this time, the bars 5 are passed in whole on the side of the inner face of the hollow partition 2, the thickness of which corresponds substantially to the length of the sleeve 3. The screw 8 is then screwed by screwdriver 11, which causes the expansion and folding of the bars 5 in the form of an umbrella on the inner face of the partition 2 (FIG. 2D). The installation is finished when the bars 5 are sufficiently folded and exert a suitable pressure for fixing the ankle in place.
L'invention est susceptible de variantes d'exécution : ainsi le nombre de dents coupantes 9 peut être quelconque, à la limite une dent seulement pourrait suffire. Ces dents 9 peuvent être venues de matière avec le reste de la cheville 1 ou éventuellement rapportées au manchon 4. Elles pourraient également etre remplacées par tout autre moyen d'autoforage de la cloison 2. The invention is susceptible of variant embodiments: thus the number of cutting teeth 9 can be arbitrary, in the end only one tooth could suffice. These teeth 9 may have come in one piece with the rest of the dowel 1 or possibly attached to the sleeve 4. They could also be replaced by any other means of self-drilling of the partition 2.
Grâce au fait que la pose de la cheville selon l'invention peut être effectuée sans perceuse, il est possible d'exécuter cette pose dans un local sans électricité. Thanks to the fact that the installation of the anchor according to the invention can be carried out without a drill, it is possible to carry out this installation in a room without electricity.
