Description
La présente invention concerne un dispositif d'assemblage pour tubes ou barres munis d'embouts taraudés. The present invention relates to an assembly device for tubes or bars provided with threaded ends.
On connatt déjà de tels dispositifs dans lesquels les extrémités d'une pluralité de tubes ou de barres sont réunies au niveau d'un noyau d'assemblage. Ces dispositifs connus présentent toutefois l'inconvénient que, pour permettre le vissage des extrémités des tubes, les noyaux doivent être de grande dimension, et par conséquent, lourds, onéreux et inesthétiques. We already know such devices in which the ends of a plurality of tubes or bars are joined at an assembly core. These known devices however have the drawback that, to allow the ends of the tubes to be screwed on, the cores must be large, and therefore heavy, expensive and unsightly.
La présente invention vise à pallier cet inconvénient. The present invention aims to overcome this drawback.
A cet effet, l'invention a pour objet un dispositif d'assemblage pour tubes nu barres munis d'embouts taraudés, caractérisé par le fait qu'il comprend un noyau creux comportant une pluralité de trous et au moins deux vis possédant chacune un filetage à chacune de ses extrémités, chaque vis traversant un desdits trous et ayant son filetage intérieur au noyau vissé sur un écrou et son filetage extérieur vissé sur l'embout d'un desdits tubes ou barres, l'un des trous ayant des dimensions supérieures à celles des écrous pc.-ur permettre l'introduction des écrous dans ledit noyau, des moyens de serrage tant prévus pour assurer le serrage de chaque vis sur l'embout correspondant. To this end, the subject of the invention is an assembly device for bare bar tubes provided with threaded ends, characterized in that it comprises a hollow core comprising a plurality of holes and at least two screws each having a thread at each of its ends, each screw passing through one of said holes and having its internal thread at the core screwed onto a nut and its external thread screwed onto the end of one of said tubes or bars, one of the holes having dimensions greater than those of pc.-ur nuts allow the introduction of the nuts into said core, clamping means provided so as to ensure the tightening of each screw on the corresponding end-piece.
Ie fait d'utiliser une vis et un écrou séparés présente un certain nombre d'avantages. Using a separate screw and nut has a number of advantages.
T-,ut d'abord, le trou par lequel sont introduits les écrous ne doit a"'r '.ue des dimensions juste supérieures à ces écrous. First of all, the hole through which the nuts are introduced must not have dimensions just greater than these nuts.
la résistance mécanique du noyau n'en est donc que très peu diminuée. the mechanical resistance of the core is therefore only very slightly reduced.
Uar ailleurs, il n'est pas nécessaire de prévoir des manipulations de a 's à l'intérieur du noyau. Celui-ci peut par conséquent être de faibles dimensions. Furthermore, it is not necessary to provide manipulations of a 's inside the core. This can therefore be small.
Les moyens de serrage peuvent comprendre par exemple une bague de serrage engagée sur le corps de la vis entre les deux filetages, ladite balte étant solidaire en rotation du corps mais pouvant coulisser librement sur iui. The clamping means may for example comprise a clamping ring engaged on the body of the screw between the two threads, said ball being integral in rotation with the body but being able to slide freely on iui.
Le montage s'effectue alors en introduisant un écrou à l'intériear du noyau, en faisant pénétrer par un des trous le filetage correspondant d'une des vis, à visser l'écrou sur ce filetage puis, à l'aide de la bague de serrage, à faire tourner la vis de manière à engager son autre filetage dans l'embout taraud du tube ou de la barre. The assembly is then carried out by introducing a nut inside the core, by making penetrate by one of the holes the corresponding thread of one of the screws, to screw the nut on this thread then, using the ring tightening, turn the screw so as to engage its other thread in the tap end of the tube or bar.
peut de la sorte assembler au noyau deux ou plusieurs tuc eu barres. can in this way assemble to the core two or more tuc had bars.
Dans un mode de réalisation particulier de l'invention, lorsque la vis est serrée, la bague a une de ses extrémités en appui sur la surface extérieure du noyau et son autre extrémité en appui sur ledit embout. In a particular embodiment of the invention, when the screw is tightened, the ring has one of its ends in abutment on the outer surface of the core and its other end in abutment on said endpiece.
On obtient ainsi une excellente résistance mécanique de la liaison entre le tube et le noyau du fait que la vis se trouve alors en traction entre l'écrou intérieur au noyau et l'embout, alors que la bague se trouve en compression. Excellent mechanical resistance is thus obtained from the connection between the tube and the core because the screw is then in tension between the nut inside the core and the end piece, while the ring is in compression.
De manière à assurer le coulissement longitudinal de la bague sur le corps de la vis et l'entrainement en rotation, ce corps et la surface intérieure de la bague peuvent comporter des canelures longitudinales complémentaires. In order to ensure the longitudinal sliding of the ring on the body of the screw and the rotational drive, this body and the inner surface of the ring may include complementary longitudinal grooves.
Avantageusement, on peut prévoir des moyens amovibles pour empêcher le coulissement de la bague sur le corps de la vis. Advantageously, it is possible to provide removable means to prevent the sliding of the ring on the body of the screw.
Ces moyens ont deux fonctions. D'une part, ils empêchent la séparation de la bague et de la vis avant le montage, évitant en particulier la perte de la bague. These means have two functions. On the one hand, they prevent the separation of the ring and the screw before mounting, in particular preventing the loss of the ring.
Par ailleurs, ils permettent de présenter convenablement l'extrémité du filetage de la vis par rapport au début du taraudage de l'embout et facilite ainsi le début du vissage. Furthermore, they make it possible to present the end of the thread of the screw suitably relative to the start of the tapping of the end piece and thus facilitate the start of the screwing.
Ces moyens amovibles peuvent par exemple comprendre une cheville engagée à force dans un trou radial de la bague, et ayant son extrémité interne en appui sur le corps de la vis, ou encore comprendre un clip pincé sur la bague et muni d'une saillie engagée dans le filetage extérieur de la vis. These removable means can for example comprise a dowel forcibly engaged in a radial hole in the ring, and having its internal end in abutment on the body of the screw, or even include a clip pinched on the ring and provided with an engaged projection in the external thread of the screw.
Avartageusement, les deux filetages de chaque vis ont des sens opposés, de scrte que, lorsque l'on serre la vis sur l'embout, le serrage de la vis sur l'écrou en est augmenté. Avartagely, the two threads of each screw have opposite directions, of scrte that, when one tightens the screw on the end piece, the tightening of the screw on the nut is increased.
Dans une forme de réalisation particulière de l'invention, le noyau est sensiblement sphérique, mais d'autres formes peuvent bien entendu être envisagées. In a particular embodiment of the invention, the core is substantially spherical, but other forms can of course be envisaged.
On décrira maintenant à titre d'exemple non limitatif un mode de réalisation particulier de l'invention en référence aux dessins schématiques annexés dans lesquels
- la figure 1 est une vue en coupe d'un dispositif selon l'invention sur lequel un seul tube est monté,
- la figure 2 est une vue en coupe selon la ligne II-II de la figure 1,
- la figure 3 est une vue en perspective d'un clip selon l'invention, et
- la figure 4 est une vue partielle en coupe montrant le clip de la figure 3 monté sur le dispositif.A particular embodiment of the invention will now be described by way of nonlimiting example with reference to the appended schematic drawings in which
FIG. 1 is a sectional view of a device according to the invention on which a single tube is mounted,
FIG. 2 is a sectional view along the line II-II of FIG. 1,
FIG. 3 is a perspective view of a clip according to the invention, and
- Figure 4 is a partial sectional view showing the clip of Figure 3 mounted on the device.
Le dispositif selon l'invention comprend un noyau sphèrique creux 1 dans lequel sont ménagés des trous de petites dimensions et un trou 3 de plus grandes dimensions. The device according to the invention comprises a hollow spherical core 1 in which are made holes of small dimensions and a hole 3 of larger dimensions.
Le nombre de trous 2 dépend du nombre de tubes tels que 4 que l'on souhaite assembler au noyau 1. The number of holes 2 depends on the number of tubes such as 4 that one wishes to assemble to the core 1.
Les tubes 4 sont munis à leurs extrémités d'embouts 5 dans lesquels est formé un taraudage 6. The tubes 4 are provided with ends 5 at their ends in which a thread 6 is formed.
Une vis 7 comporte un corps central 8 à la surface duquel sont formées des canelures longitudinales 9. La-vis 7 possède d'autre part à une de ses extrémités un filetage 10 correspondant au taraudage 6 et à son autre extrémité, un filetage 11 de sens opposé au filetage 10. A screw 7 has a central body 8 on the surface of which are longitudinal grooves 9. The screw 7 has on the other hand at one of its ends a thread 10 corresponding to the thread 6 and at its other end, a thread 11 of opposite direction to thread 10.
Le filetage 11 qui, comme on le verra ci-après, est destiné à travailler à l'intérieur du noyau 1, a de préférence une section supérieure à celle du filetage 10. Ce dernier peut en effet être contrôlé beaucoup plus facilement. The thread 11 which, as will be seen below, is intended to work inside the core 1, preferably has a cross section greater than that of the thread 10. The latter can indeed be controlled much more easily.
La vis 7 est engagée à l'intérieur d'un des trous 2 de sorte que son filetage 11 puisse être vissé sur un écrou 12. Une rondelle 13 est interposée entre " écrou 12 et la surface intérieure de la sphère 1. The screw 7 is engaged inside one of the holes 2 so that its thread 11 can be screwed onto a nut 12. A washer 13 is interposed between "nut 12 and the interior surface of the sphere 1.
Une bague 14 dont la surface intérieure est munie de canelures correspondant aux canelures 9 du corps de la vis est engagée sur ce corps de manière à pouvoir l'entralner en rotation, par exemple à l'aide d'une clé. A ring 14, the inner surface of which is provided with grooves corresponding to the grooves 9 in the body of the screw, is engaged on this body so as to be able to center it in rotation, for example using a key.
Une cheville 15, par exemple en matière plastique, est engagée à force dans un trou radial de la bague jusqu'à venir en contact avec le corps 8 de la vis 7 pour empêcher temporairement la bague 14 de coulisser ?ar rapport à cette vis. A pin 15, for example made of plastic, is forcibly engaged in a radial hole in the ring until it comes into contact with the body 8 of the screw 7 to temporarily prevent the ring 14 from sliding relative to this screw.
La rondelle 13 et l'écrou 12 ayant été introduits dans la sphère 1 par le trou 3 dont les dimensions sont prévues à cet effet, la vis 7 est vissée sur l'écrou 11 et l'extrémité du filetage 10 est engagée dans le taraudage 6 en s'aidant de la bague 14 qui est encore solidaire de la vis. The washer 13 and the nut 12 having been introduced into the sphere 1 through the hole 3, the dimensions of which are provided for this purpose, the screw 7 is screwed onto the nut 11 and the end of the thread 10 is engaged in the tapping 6 with the help of the ring 14 which is still integral with the screw.
La cheville 15 est alors retirée et le filetage 10 est vissé dans le taraudage 6 en faisant tourner la vis 7 à l'aide de la bague 14 par l'intermédiaire des canelures 9. Lorsque les extrémités de la bague 14 viennent en appui d'une part sur la surface extérieure de la sphère 1, et d'autre part sur l'embout 5, les deux filetages 10 et 11 sont bloqués, l'un dans le taraudage 6 et l'autre dans l'écrou 12, du fait que ces filetages sont inversés. The pin 15 is then removed and the thread 10 is screwed into the internal thread 6 by turning the screw 7 using the ring 14 by means of the grooves 9. When the ends of the ring 14 come to bear on the one hand on the outer surface of the sphere 1, and on the other hand on the end piece 5, the two threads 10 and 11 are blocked, one in the internal thread 6 and the other in the nut 12, because that these threads are reversed.
Le tube 4 est ainsi fermement solidarisé à la sphère 1. The tube 4 is thus firmly secured to the sphere 1.
D'autres tubes 4 peuvent alors être assemblés au noyau sphèrique 1 au niveau des autres trous 2. Other tubes 4 can then be assembled to the spherical core 1 at the level of the other holes 2.
Les figures 3 et 4 représentent une variante des moyens de solidarisation temporaire de la bague 14 par rapport à la vis 7. FIGS. 3 and 4 show a variant of the means for temporarily securing the ring 14 relative to the screw 7.
Un clip 16 est monté sur la bague 14 par pincement et possède une saillie 17 rabattue vers la vis de manière à venir s'engager dans des filets du filetage 10. Le clip 16 est maintenu sur la bague de serrage 14 tant que le filetage 10 n'est pas engagé dans le taraudage 6. Lorsque ceci est effectué, le clip 7 est retiré et le serrage s'effectue comme précédemment. A clip 16 is mounted on the ring 14 by pinching and has a projection 17 folded back towards the screw so as to engage in threads of the thread 10. The clip 16 is held on the clamping ring 14 as long as the thread 10 is not engaged in the internal thread 6. When this is done, the clip 7 is removed and the tightening is carried out as above.
Diverses variantes et modifications peuvent bien entendu être apportées à la description qui précède sans sortir pour autant du cadre ni de l'esprit de l'invention. Various variants and modifications can of course be made to the above description without departing from the scope or the spirit of the invention.
C'est ainsi, en particulier, que les cannelures qui permettent le coulissement longitudinal de la bague sur le corps de la vis tout en assurant l'entrainement en rotation pourraient éventuellement être remplacés par un ou plusieurs tétons fixés au corps de la vis et coopérant avec des fentes longitudinales de la bague. Thus, in particular, the grooves which allow the longitudinal sliding of the ring on the body of the screw while ensuring the rotational drive could possibly be replaced by one or more pins fixed to the body of the screw and cooperating with longitudinal slots in the ring.
