Description
Elément de fixation autoblocant pour tiges filetées
La présente invention concerne un élément de fixation autoblocant pour tiges, ou broches, filetées, notamment pour la fixation des montures de lampe à des tubes de suspension.Self-locking fastening element for threaded rods
The present invention relates to a self-locking fixing element for rods, or pins, threaded, in particular for fixing the lamp mounts to suspension tubes.
On sait bien que la fixation des montures de lampe aux tubes s'effectue sans exception par un assemblage fileté. It is well known that the fixing of the lamp mounts to the tubes is carried out without exception by a threaded assembly.
Cet assemblage est réalisé par vissage des éléments. Au sens des normes touchant le sujet, l'assemblage fileté dans de telles montures doit être bloqué en sorte que celles-ci ne puissent être dévissées du tube que sous un moment dépassant celui qui est prescrit. On connaît de nombreuses solutions de blocage des assemblages filetés. La plus repandue est représentée sur la figure 1. Dans cette solution, l'axe de la vis de fixation
C forme avec celui de la tige filetée un certain angle et empêche le dévissage par la destruction du filetage de la tige.This assembly is carried out by screwing the elements. Within the meaning of the standards relating to the subject, the threaded assembly in such mounts must be blocked so that they can not be unscrewed from the tube until a time beyond that prescribed. Numerous solutions are known for blocking threaded connections. The most common is shown in Figure 1. In this solution, the axis of the fixing screw
C forms with that of the threaded rod a certain angle and prevents unscrewing by destroying the thread of the rod.
En général, l'écrou, ou la tige filetée, est constitué par du cuivre ou de l'aluminium, et la vis de fixation par de l'acier, en sorte que le degré de destruction lors de la fixation de l'assemblage fileté peut être très élevé. Si l'on considère les exemples aussi bien familiers qu'étrangers, les moyens utilisés pour la fixation des montures de lampe ne satisfont néanmoins pas aux exigences posées au moment aux termes de la norme, c'est-à-dire que les montures de lampe peuvent se dévisser du tube de suspension. In general, the nut, or the threaded rod, is made of copper or aluminum, and the fixing screw is made of steel, so that the degree of destruction when fixing the threaded assembly can be very high. If we consider both familiar and foreign examples, the means used for fixing the lamp frames do not, however, meet the requirements set at the time under the standard, that is to say the lamp can be unscrewed from the suspension tube.
L'invention a pour objet un élément de fixation à l'aide duquel, sous maintien d'un assemblage fileté d'une structure géométrique déterminée, les tiges filetées puissent être fixées sans destruction au tube et à l'aide duquel aussi l'assemblage puisse être libéré en cas de besoin. The subject of the invention is a fixing element with the aid of which, while maintaining a threaded assembly of a determined geometric structure, the threaded rods can be fixed without destruction to the tube and with the help of which also the assembly can be released if needed.
Cet élément de fixation est caraciérisé par le fait que dans ltécrou est placé un ressort hélicoïdal dont le pas de filetage correspond à celui de la tige et à une au moins des extrémités duquel est établi un premier crampon coudé en direction radiale qui est fixé en talon dans la première encoche ménagée dans l'enveloppe dudit écrou. This fixing element is characterized by the fact that in the nut is placed a helical spring whose thread pitch corresponds to that of the rod and at least at one end of which is established a first crampon bent in the radial direction which is fixed in the heel in the first notch in the envelope of said nut.
Dans un mode de réalisation préféré de l'invention, aux deux extrémités du ressort hélicoïdal sont prévus un premier et un deuxième crampon coudés en 4direction radiale dont le deuxième est sortable à travers une deuxième encoche radiale établie dans l'enveloppe de l'écrou et est tordable dans cette encoche au moins dans un secteur de 500. In a preferred embodiment of the invention, at the two ends of the helical spring are provided a first and a second crampon bent in radial direction, the second of which can be pulled out through a second radial notch established in the casing of the nut and is affordable in this notch at least in a sector of 500.
Suivant une autre particularité avantageuse possible, le ressort hélicoidal forme lul-meme le filetage de l'écrou. According to another possible advantageous feature, the helical spring forms the thread of the nut.
L'invention sera mieux comprise à l'aide de la description détaillée de plusieurs modes de réalisation pris comme exemples non limitatifs et illustrés schématiquement par le dessin annexé, sur lequel
la figure 1 représente une fixation filetée connue ;
la figure 2 représente un premier mode de réalisation du ressort hélicoidal selon l'invention ;
la figure 3 représente le ressort hélåcoidal assemblé à l'écrou ;
la figure 4 représente une autre réalisation avantageuse du ressort hélicoïdal selon l'invention dans l'état assemblé à l'écrou. The invention will be better understood with the aid of the detailed description of several embodiments taken as nonlimiting examples and illustrated schematically by the appended drawing, in which
Figure 1 shows a known threaded attachment;
FIG. 2 represents a first embodiment of the helical spring according to the invention;
Figure 3 shows the helåcoidal spring assembled with the nut;
FIG. 4 shows another advantageous embodiment of the helical spring according to the invention in the state assembled with the nut.
Dans la première forme de réalisation envisagée, l'élément de fixation se compose d'un ressort hélicoïdal 1 à l'une des extrémités duquel est ménagé, comme on le voit sur la figure 2, un crampon 2 coude en direction radiale. Comme on le voit sur la figure 3, le ressort hélicoïdal 1 est placé, dans l'écrou, du côté de sortie du tube de suspension, ou de la tige filetée. L'extrémité du ressort hélicoidal placée du c8té du filetage est libre, tandis que l'autre extrémité 2 est disposée en talon dans l'encoche radiale 3 ménagée dans l'enveloppe de l'écrou. Lors du vissage intérieur de la tige filetée, les filets du ressort hélicoïdal 1 s'élargissent avec le pas correspondant, la tige filetée s'enfonce et l'assemblage se produit.Si l'on veut ensuite dévisser la broche ou le tube de suspension, le ressort hélicoîdal se coince dans le taraudage par son extrémité fixée et il en résulte une fixation sûre, ou un assemblage autoblocant. In the first embodiment envisaged, the fixing element consists of a helical spring 1 at one end of which is provided, as seen in Figure 2, a crampon 2 bend in the radial direction. As seen in Figure 3, the coil spring 1 is placed in the nut on the outlet side of the suspension tube, or the threaded rod. The end of the helical spring placed on the side of the thread is free, while the other end 2 is arranged in a heel in the radial notch 3 formed in the envelope of the nut. During the internal screwing of the threaded rod, the threads of the coil spring 1 widen with the corresponding pitch, the threaded rod sinks and assembly takes place. If you then want to unscrew the spindle or the suspension tube , the coil spring gets stuck in the thread by its fixed end and this results in a secure fixing, or a self-locking assembly.
La figure 4 correspond à une autre réalisation possible dans laquelle un crampon 2 ou 4 est coudé en direction radiale å chacune des deux extrémités du ressort hélicoSdal 1-. Figure 4 corresponds to another possible embodiment in which a clamp 2 or 4 is bent in a radial direction at each of the two ends of the helical spring 1-.
Le crampon 2 est de nouveau fixé en talon dans encoche 3, tandis que le crampon 4 est placé dans encoche radiale 5 du manteau de l'écrou de laquelle ii est sorti et peut etre déplacé de l'extérieur le long de l'arc de cercle "k". La largeur de l'encoche 5 est telle que I'on puisse tordre le crampon 4 d'au moins 500 le long de l'arc 1,k". The stud 2 is again fixed in the heel in notch 3, while the stud 4 is placed in the radial notch 5 of the mantle of the nut from which it came out and can be moved from the outside along the arc of circle "k". The width of the notch 5 is such that the crampon 4 can be twisted at least 500 along the arc 1, k ".
Le filetage du ressort hélicoldal 1 ainsi agencé, dont le pas corresppnd au pas de filetage l'écrou, se coince à la libération de l'assemblage, donnant ainsi naissance à la liaison autoblocante. Si l'on veut libérer l'assemblage fileté, on tord, par exemple au moyen d'un tournevis, le crampon 4 le long de l'arc de cercle "k" dans une direction opposée à la fixation, si bien que l'assemblage se relache et que l'on peut dévisser l'écrou d'avec la tige filetée sans difficulté particulière et dévisser de même la monture de la lampe du tube de suspension. The threading of the helical spring 1 thus arranged, the pitch of which corresponds to the thread pitch of the nut, becomes jammed when the assembly is released, thus giving rise to the self-locking connection. If you want to release the threaded assembly, you twist, for example using a screwdriver, the clamp 4 along the circular arc "k" in a direction opposite to the fixing, so that the assembly loosens and you can unscrew the nut with the threaded rod without any particular difficulty and unscrew the lamp frame from the suspension tube in the same way.
L'élément de fixation selon I'invention est aussi utilisable de façon générale dans la mesure où l'indesserra- bilité est limitée par un certain moment de sollicitation. The fastening element according to the invention can also be used generally, insofar as the indestructibility is limited by a certain moment of stress.
