Abstract

The improvements consist in: - making an inclined slot with a circular cutout in the body of hanger modules for preventing these elements from falling out before they have been locked onto the carrier cable - making modules including mechanical components with elastic clips onto which conductors and pipes are clipped - joining modules together in pairs using a stiffening rod allowing them to be hung from vertical support cables - making a graduated dial which, as a function of the loads and of the anchoring distances, displays the magnitudes of the sag in the chain, in order to adjust the tension in the carrying cable.

PERFECTIONNEMENTS AUX SYSTEMES DE FIXATION RAPIDE
DE CABLES ET TUYAUTERIES
La présente invention concerne un ensemble constitué de dispositifs simples à mettre en oeuvre pour réaliser des réseaux de cibles et tuyauteries dans ou entre des bâtiments ou des ensembles de machines
Il est particulièrement adapté à la réalisation d'instalations électriques dans des exploitations agricoles ou industrielles (chais, ateliers, entrepôts ...).IMPROVEMENTS TO QUICK FASTENING SYSTEMS
OF CABLES AND PIPING
The present invention relates to an assembly consisting of devices that are simple to implement in order to produce networks of targets and pipes in or between buildings or sets of machines.
It is particularly suitable for making electrical installations in agricultural or industrial operations (cellars, workshops, warehouses, etc.).

Il est connu que l'installation de chemins de câbles ou de tuyauteries, rendus solidaires de murs ou d'équipements exige la fixation de nombreux éléments au moyen de scellements ou pitons, et éventuellement l'installation de consolS,poteaux, portiques ou supports
La présente invention concerne la réalisation de modules de suspension, accrochés sur un câble porteur tendu entre 2 points d'ancrage, et sur lequel sont fixés par des agrafes élastiques, avec fixation instantanée par simple clipsage,des câbles, tuyaux ou organes de machines
Un perfectionnement consiste dans la façon de réaliser le module de suspension qui soutient les éléments supports des câbles et tuyauteries, permettant la fixation des modules sur un câble métallique porteur
La réalisation particulière de la pièce d'accrochage (1) comprenant une fente inclinée suivant les Fig. 1, 2, 5 et 6
Pl. 1/1 - permet de placer directement le module sur le câble porteur sans risque de chute, la pièce restant suspendue jus qu'à son blocage final . Le module setrouve en position (2) dans le fond du dièdre constitué par la fente. L'action de la vis de blocage (3) du module sur le câble, maintient ce dernier en position (4) - Fig. 1 - au fond d'une découpe semicylindrique prévue à cet effet, et permet le logement du câble et son immobilisation
La pièce d'accrochage portant la fente peut être fabriquée en métal, matière plastique ou autre matériau
Une autre façon de réaliser le blocage, avec les mêmes avantages, le câble demeurant toujours en fond du dièdre formé par la fente, est constituée par un verrou rotatif excentrique munie d'une tête carrée .(5) qui immobilise, lors de sa rotation le module sur le câble (2) - Fig. 2 - ; le verrou est luimême immobilisé après blocage sur le câble, par la vis 6 pans (6)
Un autre perfectionnement réside dans la manière de fabriquer les éléments destinés à supporter les câbles et tuyauteries, au moyen de pièces mécaniques qui sont rendues soli daires de la pièce d'accrochage -1), par une vis (10) sur les
Fig. 1, 2, 3 et 4.It is known that the installation of cable or piping paths, made integral with walls or equipment requires the fixing of numerous elements by means of seals or pegs, and possibly the installation of brackets, posts, gantries or supports
The present invention relates to the production of suspension modules, hung on a carrying cable stretched between 2 anchoring points, and on which are fixed by elastic clips, with instantaneous fixing by simple clipping, cables, pipes or parts of machines
An improvement consists in the way of producing the suspension module which supports the support elements of the cables and piping, allowing the fixing of the modules on a carrying metal cable.
The particular embodiment of the attachment piece (1) comprising an inclined slot according to FIGS. 1, 2, 5 and 6
Pl. 1/1 - allows the module to be placed directly on the carrying cable without the risk of falling, the part remaining suspended until it is finally locked. The module is located in position (2) in the bottom of the dihedral formed by the slot. The action of the module's locking screw (3) on the cable keeps the cable in position (4) - Fig. 1 - at the bottom of a semi-cylindrical cutout provided for this purpose, and allows the cable to be accommodated and immobilized
The hanging piece carrying the slot can be made of metal, plastic or other material
Another way of achieving blocking, with the same advantages, the cable always remaining at the bottom of the dihedron formed by the slot, is constituted by an eccentric rotary lock provided with a square head. (5) which immobilizes, during its rotation the module on the cable (2) - Fig. 2 -; the lock is itself immobilized after blocking on the cable, by the hexagonal screw (6)
Another improvement lies in the way of manufacturing the elements intended to support the cables and pipes, by means of mechanical parts which are made integral with the attachment part -1), by a screw (10) on the
Fig. 1, 2, 3 and 4.

Ces éléments supports des câbles et tuyauteries, se présentent sous la forme de pièces mécaniques, métalliques , plastiques, ou autres, en forme de "L" (7) -Fig. 3A -, dans les quelles sont perforés les trous calibrés destinés à recevoir par clipsage les agrafes (9), plus particulièrement destinées à la fixation des câbles; ou encore de pièces en forme de plateau (8), sur les extrémités desquels sont fixées par clipsage , sertissage ou rivetage les agrafes (11) supportant de gros câbles ou tuyaux - Fig. 2
Les Fig. 4A, 4B et 4C montrent le montage suivant les différentes combinaisons de ces éléments, présentées à titre d' exemple, permettant la disposition de 2 fois 8 câbles (Fig.These cable and pipe support elements are in the form of mechanical, metallic, plastic or other parts, in the form of an "L" (7) -Fig. 3A -, in which are perforated the calibrated holes intended to receive by clipping the clips (9), more particularly intended for fixing the cables; or parts in the form of a plate (8), on the ends of which the clips (11) supporting large cables or pipes are fixed by clipping, crimping or riveting - Fig. 2
Figs. 4A, 4B and 4C show the assembly according to the different combinations of these elements, presented by way of example, allowing the arrangement of 2 times 8 cables (Fig.

4A ); de 2 fois 2 tuyaux ou gros câbles (Fig. 4B ); ou encore 2 gros câbles ou tuyaux et 8 câbles, (Fig. 4C) . Tous ces éléments sont fixés sur le module d'accrochage par les vis (10) , ou dans le cas de montage double, par un ensem ble de vis (10) et colonnettes formant prolongateur (12) - Fig. 4A, B et C).4A); 2 times 2 pipes or large cables (Fig. 4B); or even 2 large cables or hoses and 8 cables, (Fig. 4C). All these elements are fixed to the attachment module by the screws (10), or in the case of double mounting, by a set of screws (10) and posts forming an extension (12) - Fig. 4A, B and C).

Un autre perfectionnement permettant de réaliser des modules de suspension suivant l'invention, consiste en la fabrication de pièces mécaniques, monobloc, en métal, plastique ou autre - tel que représenté sur les Fig. SA, 5B et 5C - sur lesquelles sont clipsés les organes à suspendre, au moyen des agrafes (9) et (11)
Un autre perfectionnement consiste en la réalisation des modules de suspension sous la forme de pièces monobloc en plastique par exemple, le moulage comprenant des inserts: agrafes, généralement métalliques, de support des éléments.Another improvement making it possible to produce suspension modules according to the invention consists in the manufacture of mechanical, monobloc, metal, plastic or other parts - as shown in FIGS. SA, 5B and 5C - on which the members to be suspended are clipped, by means of clips (9) and (11)
Another improvement consists in the production of the suspension modules in the form of one-piece plastic parts for example, the molding comprising inserts: staples, generally metallic, for supporting the elements.

Ou encore, le moulage plastique comporte 2 nuances de plastique, l'un dur, pour la fabrication du corps des modules (1) - Fig. 6A et 6B - l'autre en plastique rendu localement souple, et pouvant être moulé en formes d'agrafes, et lesquelles permettent le clipsage direct d'éléments, tel que représenté en (13) et (14) , sur les mêmes figures.Or again, the plastic molding comprises 2 shades of plastic, one hard, for manufacturing the body of the modules (1) - Fig. 6A and 6B - the other in plastic made locally flexible, and which can be molded into the shape of staples, and which allow direct clipping of elements, as shown in (13) and (14), in the same figures.

Plusieurs éléments modulaires, correspondant à différentes combinaisons de fixation peuvent être accouplés et bloqués par la vis (15) suivant Fig. 6
Un autre perfectionnement selon l'invention consiste en l'utilisation de 2 modules de suspension, accouplés au moyen d'une barrette-raidisseur (16) - Fig. 7 -, chacun des modu les comportant une perforation radiale prévue à cet effet traversée par des vis (19) (19) qui assuretle blocage . Cette disposition permet de supporter ( sans imposer au câble porteur une déformation au point d'accrochage du modula de suspension ) des câbles ou tuyaux en position verticale -câble porteur en (17) et tuyaux en (18), ainsi que de réaliser des coudes dans le plan vertical (20) d'un tuyau horizontal (22), le module double et sa barrette-raidisseur étant accrochés dans ce cas au câble porteur horizontal (21) - Fig. 7 -.Several modular elements, corresponding to different fixing combinations can be coupled and locked by the screw (15) according to Fig. 6
Another improvement according to the invention consists in the use of 2 suspension modules, coupled by means of a stiffening bar (16) - FIG. 7 -, each of the modu comprising a radial perforation provided for this purpose traversed by screws (19) (19) which ensures the blocking. This arrangement makes it possible to support (without imposing on the carrying cable a deformation at the point of attachment of the suspension module) of cables or pipes in a vertical position - carrying cable in (17) and pipes in (18), as well as to make elbows in the vertical plane (20) of a horizontal pipe (22), the double module and its stiffening bar being hooked in this case to the horizontal carrying cable (21) - Fig. 7 -.

Pour permettre le montage aisé des chemins de câbles et tuyaux, avec un câble porteur constitué suivant l'inven tion, et réaliser la chainette correcte permettant la mise en charge du système sans risque de détérioration des ancrages ou de rupture du porteur, un perfectionnement suivant l'invention consiste en un cadran de réglage (23)-Fig. 8 de la longueur de la flèche "f" de chaînette, comportant sur sa face arrière, une abaque, donnant les valeurs de "f" pour différent intervalles d'ancrage " A ", et pour différentes valeurs des charges uniformément réparties que représentent les câbles et tuyaux à soutenir
L'autre face du cadran, comporte une graduation des valeurs "f" de flèche de chainette à réaliser . Ce cadran gradué, est accroché au moyen de l'agrafe (24),(sertie à cet effet sur le cadran),à un fil fin tendu (25) entre les 2 points d'ancrage, au milieu de cet intervalle
Un tendeur à vis (26), sur le câble porteur, permet d'ajuster la flèche de la chai nette à la mise en place du chargement du système To allow easy mounting of cable and pipe paths, with a carrying cable made up according to the invention, and to produce the correct chain allowing the loading of the system without risk of deterioration of the anchorages or breaking of the carrier, a further improvement the invention consists of an adjustment dial (23) -Fig. 8 of the length of the chain arrow "f", comprising on its rear face, an abacus, giving the values of "f" for different anchoring intervals "A", and for different values of the uniformly distributed loads that represent the cables and pipes to support
The other face of the dial, includes a graduation of the "f" chain arrow values to be produced. This graduated dial is hung by means of the clip (24) (crimped for this purpose on the dial), to a fine stretched wire (25) between the 2 anchoring points, in the middle of this interval
A screw tensioner (26) on the carrying cable allows the boom of the net cell to be adjusted when the loading of the system is in place.
