Abstract
Description
Elément de support pour objet allongé. Support element for an elongated object.
La présente invention concerne les éléments de support pour objet allongé, tels que les échelles à câbles, les chemins de cables, les guide-câbles ou les supports de tuyaux. The present invention relates to support elements for elongated objects, such as cable ladders, cable trays, cable guides or pipe supports.
Les chemins de câbles métalliques ou en matière plastique sont généralement fabriqués à partir de tôles, de plaques, de fils ou de profilés. Metal or plastic cable trays are generally made from sheet metal, plates, wires or profiles.
Les chemins de câbles en tôle, plaques ou profilés, sont impossibles à cambrer pour obtenir des changements de direction. Il faut utiliser pour cela des coudes spéciaux préfabriqués et adaptés à la direction et à l'importance de la courbure. De plus, dans le cas où le chemin de câbles est constitué par un profilé tubulaire, l'enfilage du ou des câbles est difficile. Les chemins de câbles en fils actuellement réalisés ne nécessitent pas de coudes pré fa- briqués pour les chàngements de direction, mais il faut tout de même préalablement couper certains tronçons de fils constituant le chemin de câble. Cable trays made of sheet metal, plates or profiles are impossible to bend to obtain changes of direction. For this it is necessary to use special prefabricated elbows adapted to the direction and the extent of the curvature. In addition, in the case where the cable tray is constituted by a tubular profile, threading the cable or cables is difficult. The wire cable trays currently produced do not require pre-made elbows for the direction changes, but it is still necessary to cut certain sections of wires beforehand constituting the cable tray.
La présente invention a pour objet un élément de support pour objet allongé, qui peut être utilisé notamment comme échelle à câbles, comme chemin de câbles ou comme guide-câbles et qui peut facilement être courbé dans n'importe quel sens, cette courbure ne nécessitant ni découpe, ni utilisation d'accessoires. The present invention relates to a support element for an elongated object, which can be used in particular as a cable ladder, as cable tray or as cable guide and which can easily be bent in any direction, this curvature not requiring no cutting, no use of accessories.
L'élément de support selon l'invention est caractérisé en ce qu'il est constitué par un fil ou profilé unique plié de manie re à former une série de mailles successives, et en ce que chacune des mailles comporte deux portions de guidage latérales réunies l'une à l'autre par une portion de support, et une seconde portion de support qui relie la maille à la maille précédente ou à la maille suivante. The support element according to the invention is characterized in that it is constituted by a single wire or profile folded so as to form a series of successive meshes, and in that each of the meshes comprises two lateral guide portions joined together to each other by a support portion, and a second support portion which connects the mesh to the previous mesh or to the next mesh.
Les portions de guidage peuvent, par exemple, être en arc de cercle ou bien être pliées en U ou en V. Les deux portions de guidage d'une même maille peuvent avoir les mêmes dimensions ou bien avoir des dimensions différentes, ce qui permet d'emboîter deux éléments l'un dans l'autre. The guide portions can, for example, be in an arc of a circle or else be bent in a U or in V. The two guide portions of the same mesh can have the same dimensions or have different dimensions, which makes it possible to '' fitting two elements into each other.
Les portions de support sont avantageusement rectilignes. The support portions are advantageously rectilinear.
Elles peuvent être perpendiculaires aux plans des portions de guidage ou bien être obliques par rapport à ces plans.They can be perpendicular to the planes of the guide portions or be oblique with respect to these planes.
On a décrit ci-après, à titre d'exempls non limitatift, divers modes de réalisation de chemins de câbles selon l'invention, avec référence aux dessins annexes dans lesquels
La Figure 1 est une 'nie en perspective d'un tronçon de chemin de câbles, dans un premier mode de réalisation;;
La Figure 2 montre en plan comment le chemin de câbles de la
Figure 1 peut être cintré,
La Figure 3 montre un mode i fixation du chemin de câbles sur une paroi,
La Figure 4 est une vue semblable à la Figure 1 d'un second mode de réalisation,
La Figure 5 est une vue semblable à la Figure 1 d'un troisième mode de réalisation,
La Figure 6 montre comment les chemins de câbles de la Fig. 5 peuvent être emboîtés les uns dans les autres,
Les Figures 7 et 8 sont des vues semblables à la Figure 1 de deux autres modes de réalisation.Various embodiments of cable trays according to the invention have been described below, by way of nonlimiting examples, with reference to the accompanying drawings in which
Figure 1 is a view in perspective of a section of cable tray, in a first embodiment;
Figure 2 shows in plan how the cable tray of the
Figure 1 can be bent,
Figure 3 shows a mode i fixing the cable tray on a wall,
Figure 4 is a view similar to Figure 1 of a second embodiment,
Figure 5 is a view similar to Figure 1 of a third embodiment,
Figure 6 shows how the cable trays in Fig. 5 can be nested one inside the other,
Figures 7 and 8 are views similar to Figure 1 of two other embodiments.
Tel qu'il est représenté au dessin, le chemin de câbles est constitué à partir d'un fil d1acier 1 plié de façon à former une série de mailles successives. As shown in the drawing, the cable tray is made from a steel wire 1 bent so as to form a series of successive meshes.
Chacune des mailles comprend deux portions latérales de guidage en U renversé disposées en quinconce dans deux plans parallèles; l'une comporte deux branches verticales la et lb réunies l'une à l'autre par une branche horizontale lc alors que l'autre comporte deux branches verticales ld et le réunies l'une à l'autre par une branche horizontale lf paralldle a la branche lc. Les branches lc et lf ont ici meme longueur. Ces deux portions en U sont elles-mêmes réunies l'une à l'autre par une branche rectiligne horizontale de support lg qui est ici perpendiculaire au plan des deux portions en U.Enfin, la branche verticale le est suivie d'une branche rectiligne horizontale lh qui est parallèle à la branche lg et se raccorde à la branche verticale la de la maille suivante. Each of the meshes comprises two lateral U-shaped guide portions arranged in staggered rows in two parallel planes; one has two vertical branches la and lb joined to each other by a horizontal branch lc while the other has two vertical branches ld and joined to each other by a horizontal branch lf paralldle a the branch lc. The branches lc and lf have the same length here. These two U-shaped portions are themselves joined to each other by a horizontal rectilinear branch of support lg which is here perpendicular to the plane of the two U-shaped portions. Finally, the vertical branch is followed by a rectilinear branch horizontal lh which is parallel to the branch lg and connects to the vertical branch la of the next mesh.
Ce cheniin de câble peut facilelaent être cintré à la main, aussi bien dans le plan horizontal que dans le plan vertical. La
Figure 2 le montre coudé par torsion partiellement d'une branche verticale ld et partiellement d'une branche verticale lb; à cette figure, la référence 2 montre un câble ou un faisceau de câbles supporté par le chemin de câbles. Ce dernier pourrait également être coudé dans le plan vertical par torsion d'une branche horizontale lg et/ou d'une branche Ilt. This cable track can easily be bent by hand, both horizontally and vertically. The
Figure 2 shows the bent by twisting partially of a vertical branch ld and partially of a vertical branch lb; in this figure, reference 2 shows a cable or a bundle of cables supported by the cable tray. The latter could also be bent in the vertical plane by twisting a horizontal branch lg and / or an Ilt branch.
Le chemin de câbles peut facilement être fixé à une paroi 3 à l'aide de cavaliers 4 qui viennent coiffer# certaines des bran ches horizontales lc et 1f 1 ou certaines des branches verticales la ou lb comme représenté à la figure 3, et qui sont fixés à la paroi par exemple par des vis 5. The cable tray can easily be fixed to a wall 3 using jumpers 4 which cover # some of the horizontal branches lc and 1f 1 or some of the vertical branches la or lb as shown in FIG. 3, and which are fixed to the wall for example by screws 5.
La forme de la maille du chemin de câbles peut varier. Par exemple, les portions en U la - lb - lc et ld-le-lf peuvent être remplacées par des portions en arc de cercle 6a et 6b, comme le montre la Figure 4, ou par des portions en V. Les branches de liaison lu et lh au lieu d'être perpendiculaires aux portions en U, en
V ou en arc de cercle peuvent être disposées obliquement par rapport à ces portions, comme le montre la Figure 5. Cette dernière disposition permet un empilage des chemins de câbles lors du stockage (Fig. 6).The shape of the cable tray mesh may vary. For example, the U-shaped portions la - lb - lc and ld-le-lf can be replaced by circular arc portions 6a and 6b, as shown in Figure 4, or by V-shaped portions. lu and lh instead of being perpendicular to the U-shaped portions, in
V or in an arc can be arranged obliquely to these portions, as shown in Figure 5. This last arrangement allows stacking of the cable trays during storage (Fig. 6).
Les portions de guidage au lieu d'être perpendiculaires au plan dans lequel se trouvent les portions de support 1g et lh peuvent être obliques par rapport à ce plan, comme le montre la
Figure 7. A la limite, ces portions de support pourraient être extrêmement étroites, les branchés obliques ld et le prolongeant pratiquement les branches lb et la également disposées obliquement, mais dans le sens contraire.The guide portions instead of being perpendicular to the plane in which the support portions 1g and lh are located can be oblique with respect to this plane, as shown in the
Figure 7. Ultimately, these support portions could be extremely narrow, the branched oblique ld and substantially extending the branches lb and la also arranged obliquely, but in the opposite direction.
Dans le mode de réalisation de la Figure 8, la branche le est reliée à la branche de support# 1h par une branche de retour li qui est parallèle à la branche If, les deux branchés if et li étant dirigées dans le même sens par rapport à la branche le. Le guidecâbles peut ainsi être fixé à une paroi par deux cavaliers venant coiffer les branches If et li de sorte que la fixation est très sure et très stable. La branche lb pourrait être reliée également par une branche de retour à la branche de support 1g. In the embodiment of FIG. 8, the branch 1c is connected to the support branch # 1h by a return branch li which is parallel to the branch If, the two branched if and li being directed in the same direction relative to the branch on. The cable guide can thus be fixed to a wall by two jumpers covering the branches If and li so that the fixing is very secure and very stable. The branch 1b could also be connected by a return branch to the support branch 1g.
I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représen- té, mais en couvre, au contraire, toutes les variantes. C'est ainsi, par exemple, que les branches lc et If ou bien les portions 6a et 6b pourraient être de longueurs différentes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof. Thus, for example, the branches lc and If or the portions 6a and 6b could be of different lengths.
