22. A sheet of cable tray wall provided with an oblong mounting hole is shown in section and in plan in FIGS. 23 and 24.

 A mounting part is seen from above and from the front in FIGS. 25 and 26.

 Figures 27 and 28 show in top view and in section the assembly of a cable tray as shown schematically in Figures 21 and 22 on a console as shown schematically in Figures 23 and 24, using a part such as seen in Figures 25 and 26; - Figure 29 is a sectional view of an embodiment of a mounting rail of a console according to the invention; - Figures 30,31 and 32 are side views of a rail as shown in Figure 29, according to three embodiments; - Figure 33 is a front view of the rail shown in Figure 29; - Figure 34 is a schematic view of the mounting of a console in a support rail.

 We first refer to Figure 1.

 The console 1 seen in FIG. 1 comprises a rear part AR for mounting on a U-shaped rail, for example vertical, and a front part AV on which the cable or sheet cable trays can be mounted. As will become clear below, the console 1 can be obtained by folding or bending a single sheet, the expressions rear part and front part are therefore used here to describe the console only for simplification, the border between front part rear and rear part AR being arbitrarily fixed for the purposes of this description. This border is drawn in dashes in Figure 1.

 We first describe the front part of the console.

 This front part AV is in the form of an L-shaped profile comprising a first substantially triangular wall 2 and an upper laying wall 3 extending in a plane substantially perpendicular to that of the first wall 2.

<Desc / Clms Page number 8>

 In the embodiment shown, the console further comprises a ridge 4 projecting from the lateral edge of the laying wall 3, this ridge 4 being of a height h4 substantially constant over the entire length L of the wall laying 3, this height h4 being less than that of the first wall 2 and relatively small, typically of the order of a few millimeters.

 This edge 4 contributes to the rigidity of the console 1 and of its laying wall 3.

 As will be understood by a person skilled in the art, when high service forces are provided for the console 1, the edge 4 may be of greater height, its height possibly increasing from the distal free part 5 of the wall of laying 3 to the proximal part 6 of this laying wall 3. Such an embodiment corresponds to the sheet seen flat in FIG. 8.

 As will also be understood by those skilled in the art, the first wall 2 can be, in embodiments not shown, of a general shape other than triangular, for example rectangular or with a free curved edge 7, depending in particular on the desired aesthetic.

 The first wall 2 takes over the load from the laying wall 3. In the embodiment shown, the wall 2 is provided with a reinforcing rod or ply 8 substantially parallel to the free edge 7 of this wall 2. In other embodiments, not shown, the wall 2 and / or the edge 4 are provided with more than one fold or reinforcing rod.

 The upper laying wall 3 is provided with mounting lugs for cable trays, these lugs 9 projecting from the base plane 10 of the wall 3. The front part AV of the console thus defines a profile whose general shape is L or U, depending on the height of the edge 4, the legs 9 projecting in the opposite direction from the base of this U or L profile.

 The shape and function of these legs 9 projecting from the base plane 10 of the wall 3 will be explained in detail below.

 We will now describe the rear part AR of the console 1, with reference to FIGS. 1 and 2.

<Desc / Clms Page number 9>

 This rear part AR is in the general form of a U-shaped profile comprising a bottom wall 11 and two wings 12, 13 substantially parallel to one another.

 The bottom wall 11 is substantially perpendicular to the laying wall 3 and to the first wall 2 of the front part AV of the console 1.

 For simplification, in the remainder of this description, the bottom wall 11 will be considered to extend along a vertical plane containing a first direction D1, the laying wall 3 extending in a transverse direction D2, the width 13 of this laying wall 3 being measured in a third direction D3 called longitudinal. It is understood, however, that the bottom wall 11 is not necessarily vertical when the console 1 is used in a network of cable trays. The directions Dl, D2 and D3 define a direct trihedron.

 The bottom wall 11 is provided with at least one through hole 14 disposed above the plane of the laying wall 3. The two wings 12, 13 of the rear part of the console 1 are also each provided with a through hole 15.16 arranged above the plane of the laying wall 3.

 The holes 15, 16 are substantially opposite one another and allow the mounting of an axis or pin (not shown). This pin provides additional security when high service efforts are expected or feared for the console.

 The through hole 14 of the base wall 11 allows the fixing of the console on a support such as for example a wall, this fixing being obtained by screwing or any other equivalent means.

 The console 1 can, as a variant, be mounted in a U-shaped support rail and the wings 12, 13 of the rear part AR of the console are provided for this purpose with hooking means.

 These attachment means comprise lugs or discharge 17,18, disposed on at least one of the wings 12,13, these lugs being combined, where appropriate, with through holes formed on at least one of the wings 12,13.

<Desc / Clms Page number 10>

 In the embodiment of FIGS. 1 and 2, a first series of lugs 17 protrude from the wing 12 arranged in the extension of the first wall 2, these lugs being arranged projecting outwards from the U-profile of the rear part of the console 1.

 This first series of lugs 17 is intended to be housed in perforations of a support rail to take up the load of the console.

 A second series of lugs 18 protrude from the second wing 13 of the rear part AR of the console, these lugs 18 being arranged projecting outwards from the U-shaped profile of the rear part AR of the console 1.

 This second series of lugs 18 as will appear more fully thereafter, does not have the function of transferring the loads from the console to the support rail, these lugs, projections or reliefs 18 not crossing the perforations in the rail support.

This second series of lugs 18, in the embodiment shown, has the essential function of preventing the withdrawal or the exit of the console from its support rail, after introduction of this console as shown diagrammatically in FIG. 34
The bottom wall 11 is provided with a rib or reinforcing rod 19 arranged in the lower part. In the embodiment shown, this rib is U-shaped, the two wings of this U extending substantially in the direction Dl.

 The bottom wall 11 includes a slot 20 into which is inserted the end part of a tab 21 arranged in the extension of the base plane 10 of the laying wall 3.

 After insertion into the slot 20, this tab 21 is folded substantially at a right angle so as to come into abutment against the rear face 22 of the bottom wall 11.

 This assembly ensures great rigidity of the assembly formed by the front part AV and the rear part AR of the console 1.

<Desc / Clms Page number 11>

 In order to prevent the folding of the tab 21 against the rear face 22 from creating an additional thickness on the bottom wall 11, this bottom wall 11 is provided with a slight depression in which the tab 21 is housed during its downturn.

 We now refer to Figures 6,7 and 8.

 The console 1, comprising the front part AV and rear AR described above can advantageously be produced by folding or bending a single sheet. Stampings are made beforehand on this sheet so as to define the reinforcing rods 8,19, the lugs 17,18 and the lugs 9. The sheet is also pierced with circular or oblong holes 14,15, 16 and where appropriate other holes 23 on the sheet metal part corresponding to the bottom wall 11.

 Then, the sheet is folded along the fold lines 24.25 to form the L or U profile of the front part AV of the console 1. The sheet is then or at the same time folded along the fold line 26 allowing the insertion of the tab 21 into the slot 20, tab 21 which is then folded against the face 22 of the wall 11.

 We now refer to Figures 9 and following.

 The tabs 9 comprise an upper support wall 9a substantially planar and parallel to the base wall 10 or slightly inclined with respect to the latter. This upper support wall 9a is connected to the base wall 10 by an inclined section 9b. The support wall extends over a length, measured in the direction D2, which is greater than that of the inclined section 9b, so that the support wall 9a and the incline section 9b of each tab 9 define a groove 9c.

 When the tabs 9 are arranged in pairs, the support walls 9a border a groove 9d extending in the direction D2.

 In the embodiments of Figures 1 to 8, the pairs of legs 9 are substantially equidistant and identical.

 In the embodiments of FIGS. 1, 2 and 7, the openings in the grooves 9 c all face the distal end part 5 of the console 1.

 In the embodiments of FIGS. 3,6 and 8, the legs 9 are also arranged in pairs which are substantially identical to each other and

<Desc / Clms Page number 12>

 equidistant along the laying wall 3, but each leg is provided with two grooves 9d with opposite openings.

 As will be understood by a person skilled in the art: - the fixing of the cable trays on the laying wall may be obtained, as a variant, by the provision of at least one support tab comprising a support wall 9a and a wall of inclined connection 9b, a hole in the support wall allowing the passage of a bolt for fixing sheet cable trays; - The fixing lugs 9 can be substantially parallel and delimit a groove 9d between them as shown, one or more lugs 9 being moreover arranged perpendicular to a first series of lugs 9, so as to allow the fixing of cable trays to wire in two substantially perpendicular directions.

 The mounting of a cable tray on the console can be obtained as follows.

 Two warp threads 27, 28 from a cable tray to thread are inserted into the grooves 9c of the legs 9. Depending on the section of the warp threads and the opening of the grooves 9c, this insertion will be carried out by simple sliding or by force. If necessary, as shown in FIG. 7, the free end 29 of the support wall 9a can be plastically deformed so as to block the warp thread placed in the groove 9c. This deformation can be carried out using a manual tool such as a screwdriver for example.

 The mounting of a sheet cable tray on the console can be obtained as follows.

 A wall of a sheet cable tray, such as for example the bottom wall as shown in FIG. 10, is placed in abutment on the walls 9a of the lugs 9. A bolt-type assembly means allows while maintaining the position of the cable tray on the console, the screw 30 of the bolt passing through the groove 9c bordered by the support walls 9a.

<Desc / Clms Page number 13>

 As it appears in FIGS. 11 to 16, in other embodiments, the legs 9 are not arranged in pairs so as to delimit a groove 9d.

 A single tab as shown in FIGS. 17 and 18 allows the mounting of wire cable trays in a groove 9c and the mounting of sheet cable trays, for example by asymmetrical pinching using a bolt as shown in figure 12.

 As shown in FIG. 13, 14 and 16, the mounting tab can be of a shape such that it defines two grooves 9c, the openings of which are substantially perpendicular (FIGS. 13 and 14) or even four grooves 9c (FIG. 16).

 In Figure 15, four legs 9, each defining a thread insertion groove 9c extend substantially along the four sides of a parallelogram such as a square or a rectangle, allowing the insertion of threads in two substantially perpendicular directions Dirl and Dir2, and back and forth for each of these two directions.

 A variant assembly of a sheet cable tray is shown in FIGS. 21 to 28.

 The cable tray 31 is provided with an oblong slot 32, for example on its bottom wall. The length If of this slot 32 is substantially greater than the width Ir of the groove 9d. The edges of the support walls 9a delimiting the groove 9d are provided with reliefs such as teeth 33.

 The operator places the cable tray in a sheet so that the oblong slot 32 is substantially opposite a groove 9d of a pair of legs 9. Then the operator forcibly pushes in a part 34 provided with a part harpoon-shaped lower 35. This lower part 35 separates the two tabs 9 from one another when it is forced into the groove 9d.

 The elasticity of the legs 9 allows their use as clips, the pressure of the teeth 33 against the lower part 35 of the part 34 blocking the movement of the cable tray in the direction D2.

<Desc / Clms Page number 14>

e Selon une variante non représentée, la pièce 34 est une vis à tête non agressive et à pas correspondant à l'épaisseur des parois d'appui 9a, le maintien en position du chemin de câbles étant obtenu par vissage de cette vis sur un quart de tour ou en exerçant un léger couple de serrage.

e According to a variant not shown, the part 34 is a screw with a non-aggressive head and with a pitch corresponding to the thickness of the support walls 9a, the maintenance in position of the cable tray being obtained by screwing this screw on a quarter turn or by exerting a light tightening torque.

 According to another embodiment, the part 34 is provided with several projections, in the manner of a concrete anchor.

 As it appears in FIGS. 21 and 28, the support walls 9a are slightly inclined relative to 1 "horizontal, so as to be elastically deformed during the mounting of the part 34.

 We now refer to Figures 29 to 34.

 The mounting rail 36 of the console 1, as shown in Figures 29 to 31, comprises: - a bottom wall, or core 37 provided with through holes 38; - on either side of this core 37, two wings 39.40 provided with holes facing each other 41.

 The axes 42 of the holes 41 appear in FIG. 29, these axes being substantially mid-width of the wings 39.40.

 The axes 43 of the holes 38 appear in the figure? 9, these axes 43 being substantially mid-width of the core 37.

 The holes 41 are suitable and intended to accommodate the lugs 17 projecting from the wings 12, 13 of the console 1. These lugs 17, when placed in the holes 41, prevent any exit of the console 1 from the mounting rail 36, an increase of the load on the console leading only to support and blocking of these pins against the edge of the holes 41 through which they pass.

 The holes 41 are also suitable and intended to accommodate an axis or a pin (not shown) passing through the oblong holes 15 of the wings 12, 13 shown in FIGS. 3,6, 7 and 8. The placement of this pin provides additional safety when high operating loads are expected or to be feared for the console: in the event of the pins 17 breaking,

<Desc / CRUD Page number 15>

 as a result of too high a load on the console 1, this console will however remain maintained in the rail 36 by: - the support of the wall 3 against the pin and - if necessary, the screwing of the bottom wall 11 of the rear part AR of the console, through the holes 38 of the core 37 of the rail 36.

 Reference is now made to FIG. 34 which illustrates a method of mounting a console 1 on a support rail 36.

 In a first step, the operator introduces the rear part AR of the console 1 into the rail 36 so as to bring the first series of lugs 17 of the wing 12 of the rear part AR opposite the through holes 41 of the wing 39 of the support rail 36.

 As it appears in FIG. 34, this introduction of the console into the rail is carried out by rotating the console so as to gradually bring the bottom wall 11 of the rear part AR in a plane parallel to the core 37 of the rail. support 36.

 During this pivoting, the pins 17 are brought opposite the through holes 41 of the wing 39 of the support rail 36 and pass through them. At the same time, the lugs or projections 18 are brought opposite the through holes 41 of the opposite side 40 of the support rail 36, but do not necessarily pass through these holes 41.

 The maximum width of the rear part of the console 1 is such that there is a slight transverse play, in the direction D3, when the console is in place in the rail 36.

 The accidental exit of the console from the rail 36 is however impossible, despite this slight transverse play by the presence of the second series of lugs 18 which abut against the edges of the holes 41 of the wing 40 during any movement console up or rotate.

 In order to prevent the operator from being tempted to mount the console by fixing the pins 18 in the holes 41 of made 40, not a pivoting movement opposite to that of FIG. 34, several measures can be taken, alone or in combination :

<Desc / Clms Page number 16>

 the lugs 18 can be simple reliefs obtained by pushing back without cutting material, these reliefs not allowing the load transfer from the console to the rail, their passage through the holes 41 of the wing 40 ensuring only moderate resistance to loads on the console; - Made 40 is devoid of holes 41 and has only recesses obtained by embossing without cutting material, recesses in which the pins 18 are housed.

In other embodiments, not shown: - the rear part AR of the console 1 is provided on one of its wings
12.13 of through holes in which are housed latching tabs formed on a wing of the support rail 36; the rear part AR of the console 1 is provided on its two wings 12, 13 with through holes, hooking lugs formed in one of the wings of the support rail 36 which is received in the through holes of one of the wings of the rear part of console 1, reliefs or projections formed on the other wing of the support rail coming opposite the holes passing through the other wing of the rear part of console 1, preventing the accidental exit of the console after its pivoting mounting .

 In other words, the rear part AR of the console and the support rail are provided, in the embodiments shown, with male members 17, 18 and female 41 respectively for hooking and holding the console 1 in overhang, these male and female organs being able to be interchanged.

 Obviously, in another embodiment, the console can be introduced by snapping it into the support rail, by the play of the elasticity of the lugs disposed on the wings of the rear part AR of the console, these lugs being deformed by force during the introduction of the console into the support rail 36.

 Advantageously, the holes 41 housing the lugs 17 transferring the load from the console 1 are in the form of a comma or keyhole, as it appears in FIGS. 30 and 31. Thus, when the load exerted on the console 1

<Desc / Clms Page number 17>

 cantilever increases, the lugs 17 sink into the inclined slots 44 of the holes 41 thus giving a certain elasticity of the assembly. This insertion of the pins in the holes 40 is accompanied, as understood by a person skilled in the art, of the bringing together and of the support, if applicable, of the bottom wall 11 of the console 1 with the core 37 of the support rail 36 (see figure 34c).

 In FIG. 34, the wings 12, 13 of the rear part of the console 1 are not parallel to each other. In this embodiment, the wedging of the console in the rail is reinforced by this taper of the rear part of the console 1.

 The invention provides a console for cable trays or any other equivalent product, allowing at the same time: - the support for sheet cable trays or wire cable trays, as shown in FIGS. 7 and 8 ; - the support on very wide surfaces; - rapid, inexpensive mounting of the console on a rail or directly on a civil engineering wall; - an assembly reducing the risk of injury to operators and cables, the console being devoid of sharp edges.
