"Fixing accessory for path son in cables, and son cable tray provided with at least such an accessory"
The present invention relates generally to the son raceways.
As is known, the son cable trays comprise a mesh shape, the son of two different types, namely, firstly, longitudinal son, commonly called warp son, running longitudinally of rectilinear or quasi-rectilinear manner over their entire length, and on the other hand, disposed transversely from place to place along these longitudinal son, and appropriately attached thereto, transverse son constructed as U, commonly called son frame, the combination forming three panels, in practice plane or substantially plane, namely, a bottom panel and two side panels, commonly referred to as wings.
Son these cable trays are commonly used to ensure, in the manner of a chute, support, housing and protection of elongate members such as electrical cables or the like, or tubes, for example instrumentation or transport fluids.
By electric cables is meant here and in the following, not only cables transport and distribution of electric energy, but also the cables and fibers adapted to transmit information electrically, optically or other.
In what follows, to facilitate the presentation, we will discuss electric cables; but of course all that is said about electrical wiring is valid for any element of the lanky guy.
With regard to electrical cables, the son cable trays have many advantages that make them enjoy electricians, and, in particular, the benefits of ease of installation, and therefore economy, flexibility, power cables which can be released by any of their mesh, transparency, and therefore identification of electric cables, ventilation, cleanliness, safety, both for electric cables and users, and performance.
But to date, the fixing of electrical cables either of their panels, which is necessary to maintain the electrical cables, which is done in practice using past clamps transversely loop around one or the other of their longitudinal son by sandwiching one or more of these electrical cables, not always entirely satisfactory.
The reason is, in particular, that their son necessarily intersect at different levels, the longitudinal son being in practice arranged outside transversal son.
As a result, if they are not sufficiently rigid, electric cables come marry the corresponding depressions.
In fact, it is frequently possible to observe these electrical cables are thus subject to wavy deformation, especially when it comes to electrical cables relatively small diameter.
Besides this wavy deformation can sometimes be considered unsightly, it can also be detrimental to the sustainability of electric cables and / or the quality of their performance. II is particularly true for electric cables capillary inside wire suitable for hardware connection networks for which the diameter of the electrical conductors is only a few tenths of a millimeter.
In addition, irrespective of the nature and / or the diameter of the electrical cables, clamps ensuring the maintenance thereof can inadvertently move along the longitudinal wire they surround, so that ultimately the maintaining these electrical cables is not fully mastered.
The present invention generally relates to an arrangement for avoiding these disadvantages and leading in addition to other benefits. It has been proposed to avoid these drawbacks, especially in WO 99/06746, a cable tray to son the kind comprising, in mesh form, the son of two different types, namely, firstly, the son longitudinal, which run longitudinally over its entire length, and on the other hand, disposed transversely from place to place along these longitudinal son, and appropriately attached thereto, transverse son constructed as U, the assembly , generally in the manner of a trough, three panels, namely a bottom panel and two side panels, this path son in cables being provided locally on any one of its panels, at least accessory, referred to hereinafter for convenience attachment accessory, including, on one hand, securing means by which it is secured to the panel that team, and, secondly, at least one hole, therethrough from side to side, and by which it is adapted to receive one fastening member, such as clamp, bolt or the like.

Thus, any undulating deformation between their successive supports is preferably avoided for electric cables. According to this document, the attachment feature comprises a cross, for the constitution of its securing means on the one hand, a first attachment surface, by which it bears on at least one external thread and, on the other hand, a second attachment surface, which is facing the first attachment surface, and by which it is engaged in at least two inner son the present invention aims to provide a cable tray of the above kind wherein the mounting accessory may be secured to the cable tray on two son of the cable tray which are parallel and of the same type, namely two longitudinal son or two transverse son, the fixing accessory is therefore easy to achieve . Thus, according to the invention, a fixing accessory intended to be fixed by elastic pinching locally to a cable tray of the above kind is characterized in that it comprises for the constitution of the means of securing the one hand, a first attachment surface, which is intended to be engaged in at least one wire and, on the other hand, a second attachment surface, which is facing the first attachment surface, and which is intended to bear on at least two son of the same type as said wire.
The subjugation of the fixing accessory of the invention in the way that son team cables are simply made of himself, in the manner of a simple click, pinch at least one thread of this cable tray, without the intervention of any other means or auxiliary fastener.
In addition, the fixing accessory is advantageously removable, which, if desired, allows removal and recovery. Furthermore, the fixing accessory according to the invention is advantageously wedged in position on the path in that son team cables, both laterally and longitudinally, and, through it, it is advantageously of the same or fasteners it receives.
In particular, with this mounting accessory clamps implemented for maintenance of electrical cables are advantageously wedged longitudinally in position on the way to son cables, the benefit of a better control of maintenance of electrical cables and the durability of this support.
But in addition to the ease and available for the implementation of these clamps, the fixing accessory of the invention has other advantages.
In particular, it allows, if desired, in the same way as the accessory of the document already cited, implement, parallel to each other, in the son in cable tray, two angle separation defining in this way in son cables, a separate compartment, which can be put to use for receiving particular electric cables, particularly when these must be protected by a metal screen and which, optionally, may to be closed by a cover

I 3 and two side panels 1 4.
In practice, the son 1 1, 1 2 are son metal, and more specifically, steel son, and, where they cross, they are secured to each other by welding.
By construction, the son January 1, January 2 intersect at different levels. In practice, the longitudinal son January 1 are at a lower level, and the transverse son 1 2 a higher level.
In other words, the longitudinal son 1 out of 1 extend outside the transversal son February 1.
In the embodiment shown, all son 1 1, 1 2 are round son.
In other words, they all have a circular cross section. For example, and as shown, the diameter of it is the same for everyone, but it is not necessarily always the case.
Other cross-sectional shapes are possible for the son: square, rectangular, round-flattened, polygonal or other; the notion of diameter so here overlaps the width or thickness of the wire according to the shape of its section. In the embodiment shown, the bottom panel 1 3 comprises two longitudinal son January 1st, and, at each pitch P, these longitudinal son
II delimit, with the transverse son 1 matching 2, a mesh.
But, as before, the number of longitudinal son January 1 that comprises the bottom panel 1 3, and, therefore, the number of stitches that form each pitch P, may be different.
In the embodiment shown, each of the side panels 1 4 there are only two longitudinal son 1 1, namely, a longitudinal wire 1 1 Intermediate, which substantially takes place at mid-height, and a longitudinal yarn 1 1 bank. But, as before, the number of longitudinal son 1 1 may be different. In particular, the side panels 1 4 may, like the bottom panel 1 3, forming stitches, and extension that the meshes of this bottom panel 1 3 or of different extension.
In the embodiment shown, the longitudinal wire 1 1 side of the side panels 1 4 comprises, from place to place, according to the pitch P of the corrugations 1 5 on whose behalf it is abutted to the transverse son 1 2 but is not necessarily always the case.
As illustrated in Figure 1, the path in son 1 0 cables is intended to ensure the support, housing and protection of electric cables, and for the maintenance thereof, it is implemented organs attachment, in this case clamps.
According to the invention, the cable duct in one son 0 has, locally, on any one of its panels 1 3, 1 4, and in this case, in the embodiment shown, on its panel 1 bottom 3, at least one accessory 1 6, said ICI fixation fitting, comprising on the one hand, following the modalities described in greater detail hereinafter, securing means by which it is made integral with the panel 1 3, 1 4-it equips, in this case the bottom panel 1 3, and, secondly, at least one bore 26,27 therethrough from side to side, and by which it is adapted to receive any fixing member, and, for example, in the case of a hole 27, a clamp.
Of course, the way in son 1 0 cables can be equipped with several accessories attachment 1 6, some of which, at least, are aligned, being staggered from place to place along its length. Preferably, all accessories fixing June 1 employed are identical to each other.
Only one of them will be described HERE.
In the illustrated embodiment, the fixing accessory
1 6 is in the general form of a sheet metal plate cut phee U-section having a core 1 7 and two flanges 1 8; in its central region, the core 1 7 has a groove 1 9 extending longitudinally, that is to say parallel to the flanges 1 8; the bottom 20 of the groove 1 9 is with respect to the core 1 7, the same side as the free edge of the wings 1 8.
The bottom 20 of the groove 1 9 of the core 1 7 of the mounting accessory 1 6 has cutouts 21 U, here two cuts 21 defining securing tabs 22 extending parallel to the groove 1 9 and one of whose sides constitutes the first attachment surface, in the illustrated embodiment, the cutouts 21 also affect partially the flanks ICI inclined of groove 1. 9
The securing tabs 22 are associated notches of coverage 23 formed on the edge of the wings 1 8; these securing notches 23 are advantageously arranged transversely to groove 1 9 at the right of the part of the tongue of coverage corresponding 22 close to its root; the portion of the securing slots 23, which is facing the first attachment surface, is the second securement surface; as can be seen in the drawings, each bracing tab 22 are associated two securing slots 23 each formed on each wing 8 January.

Figures 1 0 and 1 1 illustrate the securing of the fixing accessory 1 6 to the path of cables 10, the two longitudinal son 1 1 1 of the bottom panel 3 of raceway 1 0 clamps are somehow taken sandwiched between, on one hand, each bracing tab 22 and on the other hand, the bottom 23 of the securing notches associated with each bracing tab 22; ICI, the securing notches 23 have a trapezoidal shape closely conforming to the longitudinal son Section 1 1.
Thus, the mounting accessory 1 6 is held, with its fastening means, in all directions relative to the raceway 1 0.
To facilitate the introduction of the fixing accessory 1 6 in its position shown in Figs 1 0 and 1 1, it is preferred border securing each notch 23 of a ramp 24 whose base has a notch 25 said positioning. The locating notch 25 is at the right of the web of the U of the U-shaped cut defining the bracing tab 22, so that access to the positioning slot 25 is free, the securing tabs 22 not extending square to the positioning recesses 25. the two cuts of each wing 1 8, 23 and 25 defining the slots separated by the ramp 24, and the securing tabs 22, are offset parallel to the groove 1 9 of a length equal to the transverse distance which separates two longitudinal son 1; therefore, placing the fixing accessory 1 6 of the bottom panel 1 3 of raceway 1 0, 6 and 7, the positioning recesses 25 come naturally styling longitudinal son 1 1; the mounting accessory 1 6 according to the invention extends astride two longitudinal son 1 1 and thus comes to rest against these longitudinal son 1 1 from the bottom of its positioning notches 25. It is then sufficient to move the mounting accessory 1 6 relative to the raceway 1 0 according to the arrow F7 of Figure 7, along the transverse son 1 2 concerned; through here cylindrical longitudinal son 1 1, the bracing tabs 22 mounted on said son 1 1, while they move up the ramp 24; during this movement, shown in Figures 8 and 9, the securing tabs 22 are lifted elastically; the strips 24 and tongues 22 pinch and thus sandwiching the longitudinal son 1 1; continuing the displacement according to arrow F9 of Figure 9, the longitudinal son January 1 crossing strips 24 and fall into the securing grooves 23, which advantageously provides a releasable locking of the assembly on the way to son cables 1 0.
Following a reverse process of the foregoing, removal of the mounting accessory 1 6 according to the invention is possible, so that it is advantageously removable.
To complete the securing, it can if desired partially wrap the securing tabs 22 around son 1 1 using a tool such as a screwdriver through the rectangular opening 28 that they present at their end
By construction, the mounting accessory 1 6 according to the invention has, preferably, a conformation such that it preferably extends substantially flush with the transverse son February 1.
For the seat of power cables, all you need is, from place to place along these, such accessories attachment 1 6.
In the embodiment shown, the fixing accessory 1 8 next to the invention comprises at least two bores 26, 27 of different types, namely, at least one bore 26 of circular outline and at least one hole 27 elongate in a buttonhole .
Preferably, there are several bores 26 and a plurality of bores 27.
For example, the various holes 26, 27 thus provided are distributed in rows, parallel to the flanges 8 January.
In the embodiment shown, there are thus three rows of holes 26, 27.
The central row, which extends along the center line of the fixing accessory 1 6 according to the invention comprises, for example, as shown, a bore 26 in its central area, and two bore 26 on both the other of the previous, slightly smaller diameter. The lateral rows do not include, for example, and as shown, that bores 27.
In practice, all the bores 27 are elongated transversely, ie perpendicularly to the wings 1 8 To maintain electrical cables, it is sufficient, then, at each of these accessories binding 1 6, to enclose these electric cables with one or more clamps together with such an accessory attachment 1 6, by passing this or these clamps through bores 27 of the mounting accessory 1 6. it is possible to shift by fastening materials 1 6 except implemented jointly at least one bracket having a fixing flange, which, from place to place, and according to a regular pitch, is perforated with elongated holes longitudinally in a buttonhole configuration for the passage of a fastening member , in this case a bolt. To be constrained to a path in one son 0 cables, they are fixed, by bolts, for fixing accessories 1 6 according to the invention fitted in this son raceway 1 0, thanks to holes 26 of these accessories binding 1 6
