Description Description
La présente invention se rapporte à un moyen d'assemblage de deux plaques perforées, ainsi qu'à son utilisation pour le montage d'un chemin de câbles. The present invention relates to a means of assembling two perforated plates, as well as to its use for mounting a cable tray.
Pour le montage d'étagères, de chemin de câbles, ou de tout autre structure modulaire comportant des éléments à assembler, on utilise généralement comme moyen de fixation de ces éléments des boulons avec écrous, des goupilles, etc. Or, de tels moyens d'assemblage présentent des inconvénients, plus particulièrement lorsqu'il s'agit de l'assemblage d'un grand nombre d'éléments; en effet, l'utilisation de boulons et d'écrous rend l'opération très longue, et d'autre part ces moyens d'assemblage de même que d'autres moyens tels que des goupilles, peuvent se révéler insuffisants en ce qui concerne leur blocage pour résister par exemple à des vibrations constantes. For mounting shelves, cable trays, or any other modular structure comprising elements to be assembled, bolts with nuts, pins, etc. are generally used as a means of fixing these elements. However, such assembly means have drawbacks, more particularly when it comes to assembling a large number of elements; indeed, the use of bolts and nuts makes the operation very long, and on the other hand these assembly means as well as other means such as pins, may prove to be insufficient as regards their blocking to resist for example constant vibrations.
Le but de cette invention consiste donc à fournir un moyen d'assemblage qui ne présente pas les inconvénients précités, c'est-à-dire qui puisse être verrouillé efficacement et facilement en position de service en une seule et simple opération. The object of this invention therefore consists in providing an assembly means which does not have the aforementioned drawbacks, that is to say which can be locked efficiently and easily in the service position in a single and simple operation.
Le moyen d'assemblage selon l'invention, qui vise à atteindre le but précité, présente les caractéristiques définies dans la revendication 1. The assembly means according to the invention, which aims to achieve the above object, has the characteristics defined in claim 1.
Un autre objet de cette invention consiste en l'utilisation du moyen d'assemblage selon l'invention pour ie montage d'un chemin de câbles, telle que définie dans la revendication 5. Another object of this invention consists in using the assembly means according to the invention for mounting a cable tray, as defined in claim 5.
Le dessin annexé illustre l'invention schématique-ment et à titre d'exemple. The accompanying drawing illustrates the invention schematically and by way of example.
La figure 1 est une vue en perspective d'une portion d'un chemin de câbles dont les éléments constitutifs sont assemblés par deux plaques fixées par le moyen d'assemblage selon l'invention. Figure 1 is a perspective view of a portion of a cable tray whose constituent elements are assembled by two plates fixed by the assembly means according to the invention.
La figure 2 est une vue en plan d'une réalisation du moyen d'assemblage selon l'invention, et la figure 3 est une vue en coupe transversale dudit moyen en position de service verrouillée pour maintenir ensemble des plaques perforées. Figure 2 is a plan view of an embodiment of the assembly means according to the invention, and Figure 3 is a cross-sectional view of said means in the locked operating position to hold together perforated plates.
En référence tout d'abord à la figure 1, deux profilés métalliques en U 1 présentant des perforations longitudinales allongées 2 et des bords supérieurs rabattus 3 sont assemblés par l'entremise de deux plaques métalliques 4 également perforées fixées latéralement contre la face interne des parois verticales 5 des profilés 1, de manière à former une portion de chemin de câbles, selon une technique connue. L'invention réside ici par contre dans la fixation de la plaque de raccordement 4 aux parois latérales 5 des profilés 1, les moyens habituellement employés, tels que goupilles, boulons-écrous, etc., étant remplacés par un bouton de fixation 6, constituant l'objet de la présente invention. Referring firstly to FIG. 1, two metal U-shaped profiles 1 having elongated longitudinal perforations 2 and folded upper edges 3 are assembled by means of two metal plates 4 also perforated fixed laterally against the internal face of the walls vertical 5 profiles 1, so as to form a portion of cable tray, according to a known technique. The invention resides here on the other hand in the fixing of the connection plate 4 to the side walls 5 of the profiles 1, the means usually employed, such as pins, bolts-nuts, etc., being replaced by a fixing button 6, constituting the object of the present invention.
Le bouton de fixation 6, tel que représenté à titre d'exemple sur les figures 2 et 3, comporte une tête 7, ici de forme circulaire, un pied ou base 8, la tête 7 et le pied 8 étant reliés par un tronc central 9 perpendiculaire aux plans des deux éléments précités. Le pied 8 présente une forme générale rectangulaire, avec ici les petits côtés légèrement bombés, et dont la longueur est inférieure au diamètre de la tête 7; comme montré sur la figure 2, le pied est disposé, vu en plan, selon un diamètre de ladite tête. D'autre part, ses dimensions sont telles qu'il peut être introduit librement dans les perforations allongées 2 que présentent tant les parois verticales 5 des éléments de chemin à assembler que la plaque de raccordement 4, ceci pour une position relative dans laquelle l'axe longitudinal du pied 8 et celui des perforations allongées coïncident approximativement. The fixing button 6, as shown by way of example in FIGS. 2 and 3, comprises a head 7, here of circular shape, a foot or base 8, the head 7 and the foot 8 being connected by a central trunk 9 perpendicular to the planes of the two aforementioned elements. The foot 8 has a generally rectangular shape, here with the slightly curved short sides, and whose length is less than the diameter of the head 7; as shown in Figure 2, the foot is arranged, seen in plan, along a diameter of said head. On the other hand, its dimensions are such that it can be freely introduced into the elongated perforations 2 which have both the vertical walls 5 of the path elements to be assembled and the connection plate 4, this for a relative position in which the longitudinal axis of foot 8 and that of the elongated perforations approximately coincide.
D'autre part, comme représenté sur la coupe de la figure 3, la face interne de la tête 7 présente une portion annulaire périphérique plane 10' et une portion centrale conique 10, avec une inclinaison (angle a) dirigée vers l'intérieur de la tête 7, et de ladite portion périphérique 10' jusqu'au tronc central 9. Selon une variante non illustrée, la portion périphérique plane 10' pourrait être réduite à la seule arête périphérique de la face interne de ladite tête 7. On the other hand, as shown in the section of FIG. 3, the internal face of the head 7 has a planar peripheral annular portion 10 ′ and a conical central portion 10, with an inclination (angle a) directed towards the interior of the head 7, and from said peripheral portion 10 ′ to the central trunk 9. According to a variant not illustrated, the planar peripheral portion 10 ′ could be reduced to the single peripheral edge of the internal face of said head 7.
Le pied ou base 8 présente quant à lui deux faces supérieures 11 coniques ou simplement inclinées (angle ß), en direction de la tête 7, et des extrémités longitudinales dudit pied jusqu'au tronc central 9. The foot or base 8 has two conical or simply inclined upper faces 11 (angle ß), in the direction of the head 7, and from the longitudinal ends of said foot to the central trunk 9.
Enfin, la distance verticale e entre l'arête phéri-phérique de la face inférieure 10' de la tête 7 et l'extrémité longitudinale de la face 11 du pied 8 est telle qu'elle corresponde approximativement à l'épaisseur des deux plaques 4, 5 superposées à fixer l'une à l'autre. Finally, the vertical distance e between the peripheral edge of the lower face 10 'of the head 7 and the longitudinal end of the face 11 of the foot 8 is such that it approximately corresponds to the thickness of the two plates 4 , 5 superimposed to be fixed to each other.
Dans la forme d'exécution illustrée à titre d'exemple, les dimensions du bouton de fixation sont les suivantes: diamètre de la tête = 25 mm, diamètre du tronc central = 6, 5 mm, longueur du pied = 14 mm, distance d'ouverture e = 2, 7 mm, hauteur totale du bouton = 8 mm; a = 5° et ß = 8°. In the embodiment illustrated by way of example, the dimensions of the fixing button are as follows: diameter of the head = 25 mm, diameter of the central trunk = 6.5 mm, length of the foot = 14 mm, distance d 'opening e = 2.7 mm, total height of the button = 8 mm; a = 5 ° and ß = 8 °.
En ce qui concerne l'utilisation du moyen d'assemblage selon l'invention, il convient tout d'abord de disposer les deux plaques 4, 5 à assembler de telle sorte que deux au moins de leurs perforations coïncident, puis d'y introduire le bouton de fixation 6, plus particulièrement le pied 8 de celui-ci, son axe longitudinal étant disposé en coïncidence avec celui des deux perforations superposées. Puis, à l'aide d'une pince ou d'un outil de forme adéquate (par exemple comportant une ouverture de forme correspondante à la forme extérieure du pied 8), il suffit de faire tourner le bouton 6 d'un quart de tour environ, de manière à placer son axe longitudinal perpendiculairement à celui des perforations. Lors de ce mouvement, la portion entourant les perforations 2 des plaques à assembler 4, 5 sont progressivement poussées par les faces inclinées 11 du pied 8 en direction de la portion conique 10 de la face interne de la tête 7 du bouton de fixation 6. As regards the use of the assembly means according to the invention, it is first of all necessary to arrange the two plates 4, 5 to be assembled so that at least two of their perforations coincide, then to introduce therein the fixing button 6, more particularly the foot 8 thereof, its longitudinal axis being arranged in coincidence with that of the two superimposed perforations. Then, using pliers or a tool of suitable shape (for example having an opening of shape corresponding to the external shape of the foot 8), it suffices to turn the button 6 a quarter of a turn. approximately, so as to place its longitudinal axis perpendicular to that of the perforations. During this movement, the portion surrounding the perforations 2 of the plates to be assembled 4, 5 are progressively pushed by the inclined faces 11 of the foot 8 in the direction of the conical portion 10 of the internal face of the head 7 of the fixing button 6.
Dans la position de service illustrée sur la figure 3, les deux plaques 4, 5 sont donc fixées l'une à l'autre par coincement et déformation des bords des perforations 2 dans lesquelles le bouton de fixation 6 a été introduit et pivoté. In the service position illustrated in FIG. 3, the two plates 4, 5 are therefore fixed to one another by wedging and deformation of the edges of the perforations 2 in which the fixing button 6 has been inserted and pivoted.
Le verrouillage est ainsi obtenu facilement, par une simple et unique opération, et ceci avec un résultat efficace; en effet, pour déverrouiller l'assemblage il est nécessaire de procéder à un nou- Locking is thus obtained easily, by a simple and unique operation, and this with an effective result; indeed, to unlock the assembly it is necessary to make a new

veau quart de tour du bouton de fixation 6, qui nécessite pratiquement autant de force que pour l'opération d'assemblage. quarter-turn calf of the fixing button 6, which requires practically as much force as for the assembly operation.
De préférence, et comme illustré sur la figure 1, le pied 8 du bouton 6 est disposé à l'extérieur du canal pour permettre de procéder facilement au quart de tour nécessaire, la tête 7 dudit bouton 6 se trouvant alors à l'intérieur du canal de manière à ne pas risquer d'endommager les câbles lors du tirage de ceux-ci. Preferably, and as illustrated in FIG. 1, the foot 8 of the button 6 is disposed outside the channel to allow the necessary quarter-turn to be easily carried out, the head 7 of said button 6 then being inside the channel so as not to risk damaging the cables when they are pulled.
