    [0001] The present invention relates to a coupling element for wire mesh cable tray sections, of the type which is used to connect the wire mesh cable tray sections to the wire mesh section. ends of successive sections of wire mesh cable trays used mainly to carry electrical cables, and relates to a section of wire mesh cable tray which comprises said part. Usually, screw connections are used to connect successive sections of wire mesh cable trays. In the prior art, many systems have also been developed which were used to connect successive sections of wire mesh cable trays and which avoided the use of said screw connections. The patent ES 2093949 T3 describes a section of cable duct in the form of a path or pipe consisting of (e) an asymmetric module having two complementary ends, each forming a reversible attachment coupling element, a first element coupling being constituted by at least one bar or connecting piece whose proximal end is welded to said cable tray and whose distal end is equipped with a coupling lug, the second coupling element being formed in at least a portion of the cable tray and can receive said coupling lug. The disadvantage of this proposal lies in the fact that the connecting piece is permanently welded to the wire mesh cable tray.
    [0002] The patent ES 2159099 T3 describes a coupling means for connecting support sections for cables, which is divided into two arms in the lengthwise direction, each arm being provided with mounting means for immovably locking it in its position respectively on the end zone of a first section and on the end zone of a second section. The means for mounting the first arm are independent of those of the second arm and allow to mount the coupling element only on the first section. The means for mounting the second arm on the second section comprise at least one elastic stop means cooperating with a transverse wire of the second section, once the two sections are mounted. The patent ES 2066167 T3 discloses a joint for welding a metal cable duct of the type comprising at least two flexible tongues protruding outwards and separated from each other in the longitudinal direction, one of which is adapted to be fixed by crimping on the transverse wire of one of the two sections of cable duct to be assembled end-to-end, where each of the flexible tongues is located at the height of a cavity adapted to folding. The seal according to this invention requires a screwdriver or a specific tool to facilitate its assembly. Patent FR 2208219 A discloses a device for mounting cable duct sections, and a device which comprises on the side at least two connecting pieces which are rigid in the center and flexible at each end and located between two longitudinal elements of two sections of cable duct, so that each of their ends is coupled to a transverse wire of each of the two sections of cable duct. The device according to this invention also requires a tool to facilitate its implementation.
    [0003] The patent ES 2122829 A1 discloses a stirrup for connecting or assembling end-to-end sections or cable duct branches, and describes a part formed of a metal strip with a rigid central portion and two flexible end zones with a crimping pleat intended to be applied around a transverse wire of a section of the cable duct, which comprises at least one longitudinal fold intended to come into contact with two longitudinal wires, situated in the extension of one of the other, which are part of the two sections of cable duct, this longitudinal fold comprising two different sections which have opening lines oriented in opposite directions, one towards the inside of the cable duct and the other towards the outside of the cable duct. This stirrup requires a tool to obtain its locked position. Although many of these prior art proposals do not have elements requiring screwing, they require a tool or instrument to be assembled on the wire mesh raceway as discussed above. As a result, wire mesh cable tray sections often have to be cut in place to achieve the desired lengths. When cutting the longitudinal rods of the grid, this cut is generally not as clear as when making the grids, and it is very difficult to flush the cut longitudinal rods with the corresponding transverse rods. The coupling elements of the prior art are designed such that when they are assembled on two sections of wire mesh cable tray, there is a fixed space between the adjacent transverse rods (each corresponding to a section), or so that there is no space between these adjacent transverse rods, which could be in contact.
    [0004] Therefore, when a cut-off section is to be assembled in situ, the fact that the longitudinal rods are not flush with the transverse rods means that many of the prior art coupling elements can not be assembled. because the separation between the cross rods is larger than expected. The object of the present invention is to provide a coupling element for wire mesh cable tray sections which can be assembled manually (without tools) by the installer and which can be used when one of the cable tray sections wire mesh to be bonded must be cut in place. The invention proposes a coupling element for wire mesh cable tray sections, wherein the wire mesh cable tray sections consist of longitudinal rods and transverse rods connected to each other, which consists of a plate having ends which can be coupled to transverse rods of the wire mesh cable tray, so that the height of the ends is less than the distance between the two successive longitudinal rods of the wire mesh cable tray between which is placed the coupling element, so that one of its ends has two curved extensions to the same side and, therebetween, a curved extension to the opposite side, characterized in that the other end of the coupling element comprises a corrugated zone with at least two half-waves which can each accommodate a transverse rod the wire mesh cable tray. The invention also proposes a section of wire mesh cable tray which comprises longitudinal rods and transverse rods connected to each other, where the transverse rods have a U-shape, so that they form a base and two sides, the longitudinal rods being located respectively on the base and on the sides of the cable tray, and which also comprises at least one coupling element for wire mesh cable trays which is located between two successive longitudinal rods and is coupled with two successive transverse rods, one of which is on the outside and the other on the inside, knowing that the end of the coupling element consists of two extensions curved towards the same side and, between these, with a curved extension towards the opposite side, and is coupled to the inner transverse rod, and the end bearing the corrugated zone is coupled e to the outer transverse rod. With this configuration, the invention results in a solid coupling between two successive sections of wire mesh cable tray, which allows to extend the distance between the adjacent transverse rods. Other advantages of the invention would be the following: It guarantees the electrical continuity between the cable tray sections, just like that obtained by a screw coupling. - It guarantees a maximum load between the cable tray sections, just like that obtained by a screw coupling. - It guarantees the integrity of the assembly, without the possibility of accidental "disassembly" from the system, after loading, and / or deformation of the grids in the case of such disassembly. Other characteristics and advantages of the present invention will be set forth in the following detailed description of the nonlimiting embodiment taken as an example, in relation to the appended drawing, in which: FIG. perspective of a coupling element for wire mesh cable tray sections according to the invention; FIG. 2 is another perspective view of the coupling element for wire mesh cable tray sections according to FIG. 1; FIG. 3 is a front view of the coupling element for wire mesh cable tray sections according to FIG. 1; FIG. 4 is a plan view of the coupling element for wire mesh cable tray sections according to FIG. 1; FIG. 5 is a side view of the coupling element for wire mesh cable tray sections according to FIG. 1; FIGS. 6 to 10 show an assembly of the coupling element for wire mesh cable tray sections according to FIG. 1, on a section of wire mesh cable tray; FIGS. 11 to 15 show an assembly of a second coupling element for wire mesh cable tray sections according to FIG. 1, on a section of wire mesh cable tray; FIGS. 16 to 24 show the assembly of two successive sections of wire mesh cable tray by means of two coupling elements for wire mesh cable tray sections according to the invention; and FIG. 25 shows a section of wire mesh cable tray provided with three coupling elements for wire mesh cable tray sections according to the invention. Figures 1 to 5 show several views of the coupling element 1 for wire mesh tray sections 2 according to the invention.
    [0005] Figures 6 to 25 show coupling elements 1 and sections of cable tray 2 wire mesh. These paths are formed of several longitudinal metal rods 3, 3 ', 3 "and transverse 4, 4', 4" connected to each other, the transverse rods 4, 4 ', 4 "having a U-shape, so that they form a base 15 and two flanks or sides 14, the longitudinal rods 3 'being located on the base of the path, and a few longitudinal rods 3, 3 "being located on the sides 14 of the path. Figures 1 to 5 show the coupling element 1 according to the invention, which consists of a plate with ends that can be coupled to transverse rods 4, 4 ', 4 "of lattice cable trays as shown in FIGS. 6 to 25. One end of the coupling element 1 has two extensions 5 in the form of pins or tongues curved towards the same side and, between them an extension 6 of similar shape but curved towards the opposite side The other end of the piece has a corrugated zone 7 with at least two half-corrugations 8 which can each accommodate a transverse rod 4, 4 ', 4 "of the path of wire mesh cables.
    [0006] In the embodiment shown in FIGS. 5, the corrugated zone 7 of one of the ends of the coupling element 1 comprises three half-waves 8, as can be seen better in the plan view of FIG. 4.
    [0007] This embodiment also shows that the end provided with the corrugated zone 7 also has an extension 9 in the form of a folded plate, and that the fold line 10 of this extension 9 in the form of a folded plate is located near its free end 11. The embodiment of Figures 1 to 5 shows that the central portion 12 of the coupling element 1 is flat and has through holes 13. Figures 6 to 10 show an assembly of the element of coupling 1 for wire mesh tray sections 2 according to FIGS. 1 to 5, on a wire mesh tray section 2. Figure 7 shows that the end of the coupling element 1, which comprises two extensions 5 curved towards the same side and, between these, a curved extension 6 towards the opposite side, is coupled to an inner transverse rod 4 'located after the outer transverse rod 4. This coupling is achieved with a slight manual pressure from the operator or the installer, without the use of any instrument or tool. Similarly, FIGS. 7 to 9 show that the extension 9 in the form of a folded plate situated after the corrugated zone 7 enables it to be fixed by the user or the installer in order to be able to bring the coupling element 1 closer together. the outer transverse rod 4 and couple the rod to the element. FIG. 10 shows that the end bearing the corrugated zone 7 is coupled to the outer transverse rod 4 by means of a half-wave 8 of said corrugated zone 7. FIG. 10 also shows that the coupling element 1 is assembled between two longitudinal rods 3 on one side 14 of the wire mesh tray section 2 and two transverse rods 4, 4 'of the cable tray section 2 of wire mesh, which has the effect that one of these rods is the outer transverse rod 4.
    [0008] Figures 6 to 10 also show that the height of the ends is less than the distance between the two successive longitudinal rods 3 of the wire mesh cable tray, between which is housed the coupling element 1. Similarly, the coupling element shown in these figures as a whole a height which is less than the distance between the two successive longitudinal rods 3 of the wire mesh cable tray between which it is arranged. FIGS. 11 to 15 show the assembly of a second coupling element 1 'for wire mesh cable tray sections, such as that of FIGS. 1 to 5, on a wire mesh tray section 2 according to FIGS. FIGS. 6 to 10. This second coupling element 1 'is assembled on the other side 14 of the wire mesh tray section 2, so that the coupling is the same as that described for FIGS. 6 to 10. It should be noted that the same coupling member may be disposed on one side 14 of the wire mesh tray section 2 or on the other side (or even on the base of the truss tray section). metal), whereby it is not necessary to provide different configurations or types for the coupling element according to the invention. FIG. 15 shows a section of cable tray 2 made of wire mesh which comprises on the one hand longitudinal rods 3, 3 ', 3 "and transverse rods 4, 4', 4" connected to each other, the transverse rods. 4, 4 ', 4 "being U-shaped, so that they have a base 15 and two sides 14, and the longitudinal rods 3', 3, 3" being located respectively on the base 15 and on the sides 14 of the cable tray, and which further comprises, on each side 14 of the wire mesh tray section 2, a coupling element 1, 1 'for wire mesh cable trays, which is located between two rods longitudinal 3, 3; 3 ", 3" successive and is coupled to two successive transverse rods 4, 4 ', one of which is on the outside and the other on the inside, so that the end of the element d Coupling 1, 1 ', which consists of two extensions 5 curved towards the same side and, therebetween, an extension 6 curved towards the opposite side, is coupled to the inner transverse rod 4', and end bearing the corrugated zone 7 is coupled to the outer transverse rod 4.
    [0009] FIG. 25 shows a wire mesh tray section 2 with three coupling elements 1, 1 ', 1 "for wire mesh tray sections 2 in accordance with the invention, with a coupling element. 1, 1 'on each side 14 of the section 2 of wire mesh cable tray and a coupling element 1 "coupled to the base 15 of the section 2. The coupling element 1" connected to the base 15 (of if preferred by the width of the duct Section 2 of the wire mesh cable tray of Figure 15 may be provided as a preassembled unit which has two coupling elements 1, 1 'to its ends to be connected to the other wire mesh tray section 2 'Similarly, the wire mesh tray section 2 of Fig. 25 may be provided as a preassembled unit which comprises e three coupling elements 1, 1 ', 1 "at its ends to be connected to the other section of cable tray 2' wire mesh. In the case where one of these preassembled coupling elements 1, 1 ', 1 "deforms or is damaged at the storage place or during transport, it can be dismounted without damaging the section 2 of the cable tray. Alternatively, the cable tray sections of Figures 15 and 25 may also be manually assembled in situ Figures 16 to 24 show the assembly of two successive sections 2, 2 'of wire mesh cable trays, by means of two coupling elements 1, 1 'for wire mesh tray sections 2, 2' according to the invention, previously coupled to one of these sections 2. FIG. 19 shows that the extension 9 in the form of a folded plate is introduced into the space delimited by the longitudinal rods 3 located on the side 14 of the second section 2 'of wire mesh cable tray, so that in the next step, the half-wave 8 adjacent to the bent plate extension 9 is coupled to the outer transverse rod 4 of the second wire mesh tray section 2 ', thereby obtaining the assembled unit of FIG. 24. During the assembly process, it was observed that the section 2 of wire mesh cable tray with integrated coupling elements 1, 1 'was located on the same assembly plane as the other section 2', without it being necessary to provide additional space along the vertical or horizontal axis. The plan view of FIG. 23 shows that the corrugated zone 7 situated at the end of the coupling element 1 which is connected to the adjacent section 2 'of wire mesh cable trays, makes the distance between the adjacent transverse rods 4 may vary on the two sections 2, 2 'of wire mesh cable tray to be connected. In fact, this corrugated zone 7 may be subjected to a certain bending, which allows it to have a "spacer" effect serving as a buffer providing a few millimeters more to adapt to the distance between the adjacent transverse rods 4. This is particularly useful when it was necessary to cut in place the longitudinal rods 3, 3 ', 3 "located at one end of one of the sections 2, 2' of wire mesh cable trays and when are not aligned with the outer transverse rod 4.
    [0010] The coupling elements 1, 1 ', 1 "are made of metal and can be manufactured with the desired surface finish.On the other hand, their configuration has no elements or sharp edges that could damage the cables or injure the installer during assembly.
    [0011] Although the present invention has been described herein entirely in connection with preferred embodiments, it is understood that modifications may be made within the scope of the appended claims, without this scope being limited by the aforementioned embodiments.
