Description

Title of the invention: Cable tray module / lighting support Technical field of the invention

[0001] The present invention relates to the field of electrical installations. The invention relates more particularly to a module combining a cable routing function and a lighting support function.

[0002] The invention is in particular intended to be installed in building corridors, for example metro corridors, or even in tunnels. Prior art

[0003] It is known to use structures, called cable trays, to enable the guidance and maintenance of cables (electric cables, telephone cables, optical fibers, etc.) or similar (conduits, pipes, etc.) in buildings.

[0004] Cable trays are generally formed by assembling several sections placed end to end and fixed against a wall or ceiling. The sections are generally in the form of trunking, with a U-shaped cross-section, made of sheet metal or metal wire mesh.

[0005] Such cable trays have the sole function of routing these cables or the like from one point to another. Presentation of the invention

[0006] The present invention aims to remedy the aforementioned drawbacks.

[0007] To this end, the present invention proposes a cable tray / lighting support module, called a module, extending along a longitudinal axis and comprising three longitudinal housings parallel to each other and adjoining: - two longitudinal housings, each intended for receiving cables or the like, called first housings, - a longitudinal housing intended to receive at least one light, called the second housing,

[0008] the second housing being interposed between the first two housings, each of the three longitudinal housings having an open cross-section and comprising a bottom and two longitudinal lateral walls which extend on either side of the bottom, so that the bottom and the two longitudinal lateral walls delimit a longitudinal cavity with an opening opposite the bottom,

[0009] the bottom of the second housing being arranged on the side of the opening of the first two housings, the two longitudinal walls of the second housing each forming one of the two lateral longitudinal walls of the first two housings, the other lateral longitudinal wall of each of the two first housings, called the pivoting wall, being mounted to move in rotation around a pivot axis parallel to the longitudinal axis (X), the pivoting wall of each first housing moving between a closed position, preventing access to the longitudinal cavity of the first housing, and an open position, allowing access to the longitudinal cavity of the first housing, the second housing comprising at least one system for fixing a light.

[0010] The module according to the invention advantageously offers a dual function. The module allows on the one hand to route cables and the like while serving as a lighting support.

[0011] Such a module has a reduced footprint and is quick to install.

[0012] Such a module can be advantageously installed on the ceiling of buildings, such as example on the ceiling of subway corridors, or even in tunnels.

[0013] In particular embodiments, the module may further comprise one or more of the following characteristics, taken individually or in all technically possible combinations.

[0014] In particular embodiments, the module comprises one or more crosspieces intended for fixing the module to a ceiling, each crosspiece extending along a transverse axis between the two pivoting walls, each crosspiece being fixed to the bottom of the second housing.

[0015] In particular embodiments, each crosspiece comprises, at two ends, a fallen edge, each fallen edge being directed respectively towards the longitudinal cavity of a first housing.

[0016] In particular embodiments, the module comprises one or more reinforcing element(s) configured to reinforce the three longitudinal housings, each reinforcing element extending along a transverse axis.

[0017] In particular embodiments, each reinforcing element comprises, at two ends, a fallen edge, each fallen edge being directed respectively towards the longitudinal cavity of a first housing.

[0018] In particular embodiments, the module comprises, at each first housing, one or more tilting latches, each tilting latch reversibly connecting the bottom of a first housing to one end of a crosspiece, each tilting latch moving between a locking position, in which the tilting latch extends between the bottom of the first housing and the crosspiece, and a tilted position in which the tilting latch is no longer connected to the crosspiece.

[0019] In the locking position, the tilting latch locally blocks access to the longitudinal cavity of the first housing, but helps to limit the deflection of the bottom of the first housing under the effect of the weight of the cables or the like.

[0020] In the tilted position, access to the longitudinal cavity of the first housing is no longer blocked locally by the tilting latch. The installation of cables or the like along the entire length of the module is facilitated.

[0021] In particular embodiments, each tilting latch comprises an arm and a hook, the arm being articulated at a first end and being provided with the hook at a second end.

[0022] In particular embodiments, the arm of a tilting latch is connected to the fallen edge of a reinforcing element and the hook is engaged, reversibly, in a notch made in a rim portion of the crosspiece, said rim portion being located near the end of said crosspiece.

[0023] In particular embodiments, each first housing includes a locking mechanism configured to maintain the pivoting wall in its closed position.

[0024] In a particular embodiment, the locking mechanism is a cam lock. The cam lock is preferably fixed to the pivoting wall of the first housing and is preferably arranged so that the cam can engage behind the fallen edge of one of the crosspieces of the module to lock the pivoting wall in the closed position.

[0025] The invention also relates to an assembly comprising a plurality of successive modules in accordance with at least one of its embodiments, two successive modules being connected by means of a union connector of one of the two modules, said union connector being arranged at one of the longitudinal ends of said module.

[0037] In these figures, identical reference numerals from one figure to another designate identical or similar elements. Furthermore, for reasons of clarity, the drawings are not to scale, unless otherwise indicated. Description of the embodiments

[0038] A cable tray / lighting support module according to an exemplary embodiment is illustrated in Figures 1 to 8. In the remainder of the description, the cable tray / lighting support module will simply be referred to as module 100.

[0039] The module 100 is preferably intended to be fixed to the ceiling 2 of a building or a tunnel. In one embodiment, the module is intended to be fixed directly to the ceiling. In a preferred embodiment, illustrated in FIGS. 1 to 8, the module is fixed to the ceiling 2, via a longitudinal beam 3, itself fixed directly to the ceiling. The longitudinal beam 3 and the ceiling 2 are only shown in [Fig.4].

[0040] In the remainder of the description, an XYZ reference will be associated with the module 100. The indication of the X, Y and Z axes helps to understand the module.

[0041] The X axis designates a longitudinal axis of the module, and corresponds to a longitudinal direction of said module. The Y axis designates an axis perpendicular to the X axis, and corresponds to a transverse direction of the module. The Z axis designates an axis perpendicular to the X and Y axes. As illustrated in particular in [Fig.l], the Z axis designates a vertical axis. Thus, in summary, the module 100 has a length L along the X axis, a width 1 along the Y axis, and a height H along the Z axis.

[0042] As used in the description, the terms "horizontal", "vertical", "left", "right", "top", "bottom", "above", "below", "lower", "upper" etc. refer, unless otherwise specified, to the orientation of the module in the figures.

[0043] The module 100 comprises at least three longitudinal housings 200, 300 each extending along the X axis.

[0044] Preferably, and as illustrated in Figures 1 to 5, the module 100 comprises only three longitudinal housings.

[0045] The three longitudinal housings 200, 300 are preferably parallel to each other and adjoining, as illustrated in these figures.

[0046] More precisely, the module 100 comprises: - two longitudinal housings, each intended for receiving cables or the like; these longitudinal housings, having the same function, will hereinafter be called first housings 200, - a longitudinal housing intended to receive at least one lighting 750; this longitudinal housing will subsequently be called the second housing 300.

[0047] The first housings 200 advantageously form cable paths to allow the guiding and holding of cables and the like (not shown in the figures).

[0048] By cable or the like, we mean any elongated element making it possible in particular to electrically, optically or fluidically connect two elements together, such as for example a cable or a bundle of cables, electrical, optical or other, a sheath, a fluid pipe, etc.

[0049] The first housings 200 are preferably of the same shape and size. They extend over the entire length L of the module, between two longitudinal ends 110 of said module.

[0050] Each first housing 200 has an open cross-section and comprises a bottom 210 and two longitudinal side walls 220, 240 which extend on either side of the bottom, so that the bottom 210 and the two longitudinal side walls 220, 240 of each first housing 200 delimit a longitudinal cavity 230 with an opening opposite the bottom 210, as illustrated in [Fig. 1] to 3.

[0051] By cross section is meant a section in the YZ plane.

[0052] The bottoms 210 of the first housings 200 are preferably coplanar and extend in an XY plane.

[0053] The second housing 300 is interposed between the first two housings 200. It extends over the entire length L of the module 100, between the two longitudinal ends 110 of said module.

[0054] The second housing 300 has an open cross-section and comprises a bottom 310 and two longitudinal lateral walls 320 which extend on either side of the bottom 310, such that the bottom 310 and the two longitudinal lateral walls 320 of the second housing 300 delimit a longitudinal cavity 330 with an opening opposite the bottom 310.

[0055] The second housing 300 is arranged in an inverted manner relative to the first two housings 200. In other words, the bottom 310 of the second housing 300 is arranged on the opening side of the first two housings 200. The bottom 310 of the second housing 300 preferably extends in a plane parallel to that of the bottoms 210 of the first housings 200.

[0056] In the configuration where the module 100 is fixed directly to the ceiling 2, the module 100 is arranged so that the openings of the first housings 200 and the bottom 310 of the second housing 300 are opposite the ceiling 2.

[0057] In the configuration where the module 100 is fixed to the ceiling 2 via the longitudinal beam 3, the openings of the first housings 200 are opposite the ceiling 2, and the bottom 310 of the second housing 300 is opposite the longitudinal beam 3.

[0058] The first and second housings 200, 300 are adjoining at the level of their lateral longitudinal walls 220, 240, 320.

[0059] Preferably, and as illustrated in Figures 1 to 5, the two lateral longitudinal walls 320 of the second housing 300 each form one of the two lateral longitudinal walls 220 of the first two housings 200. In other words, one lateral longitudinal wall 320 of the second housing 300 forms one of the two lateral longitudinal walls 220 of one of the first two housings 200 and the other lateral longitudinal wall 320 of the second housing 300 forms one of the two lateral longitudinal walls 220 of the other of the first two housings 200.

[0060] The lateral longitudinal walls 320 of the second housing 300 (and therefore, the aforementioned lateral longitudinal walls 220 of the first two housings 200) are walls that are fixed in a rigid manner relative to the bottom 210 of the first two housings 200 and to the bottom 310 of the second housing 300. By the term fixed in a rigid manner, it is meant that there is no degree of freedom between the lateral longitudinal walls 320 of the second housing 300 and the bottoms 210, 310 of the first two housings 200 and of the second housing 300.

[0061] In the preferred embodiment described in connection with the figures, the lateral longitudinal walls 320 of the second housing 300 are parallel to each other and perpendicular to the bottom 310 of said second housing 300.

[0062] In alternative embodiments, not shown in the figures, the lateral longitudinal walls 320 of the second housing 300 are divergent, that is to say they tend to move away from each other from the bottom 320 of the second housing 300 in the direction of the opening of the second housing 300, or convergent, that is to say they tend to move towards each other from the bottom 320 of the second housing 300 in the direction of the opening of said second housing.

[0063] Similarly, and still in connection with the figures, the lateral longitudinal walls 220, 240 of the first housings 200 are parallel to each other and perpendicular to the bottom 210 of said first housings.

[0064] In alternative embodiments, for one or both of the first housings 200, the lateral longitudinal walls 220, 240 are divergent, that is to say they tend to move away from each other from the bottom 210 of the first housing 200 in the direction of the opening of said first housing, or convergent, that is to say they tend to bring one closer to the other from the bottom 210 of the first housing 200 towards the opening of said first housing.

[0065] Preferably, and as illustrated in Figures 1 to 3, the bottom 210 of the first housings 200, the longitudinal lateral walls 320 and the bottom 310 of the second housing 300 are made in a single piece, for example by laser cutting then folding a sheet metal blank.

[0066] In a preferred embodiment, and as illustrated in FIGS. 1 to 3, the bottom 210 of the first housings 200, the lateral longitudinal walls 320 and the bottom 310 of the second housing 300 form a transverse profile in the shape of a capital omega.

[0067] The other lateral longitudinal wall 240 of each of the first two housings 200, that is to say the one not connected to the bottom 310 of the second housing 300, is called the pivoting wall and is mounted to be able to rotate about a pivoting axis parallel to the axis X, as illustrated in FIGS. 1 to 3.

[0068] The pivoting wall 240 of each first housing 200 moves between a closed position and an open position. In the closed position, the pivoting wall 240 of the first housing 200 is configured to prevent access to the longitudinal cavity 230 of the first housing 200. In the open position, the pivoting wall 240 is configured to allow access to the longitudinal cavity 230 of the first housing 200.

[0069] It should be noted that this access to the longitudinal cavity 230 of the first housing 200 is the only possible access, when the module 100 is installed on the ceiling 2, as will be described later.

[0070] In the example of [Fig. 1], the pivoting wall 240 of the first housing 200 located on the right of [Fig. 1] is in the closed position. In the example of Figures 2 and 3, the pivoting wall 240 of the same first housing 200 is in the open position.

[0071] Each pivoting wall 240 of a first housing 200 is capable of pivoting through an angular range of at least 90°, preferably 180°, as illustrated in FIGS. 2 and 3.

[0072] The pivoting wall 240 of each first housing 200 is preferably assembled to the bottom 210 of the first housing 200 by a pivot connection.

[0073] In a preferred embodiment, the pivot connection can be achieved by one or more hinges 250. In the non-limiting example of Figures 1 to 3, for the pivoting wall 240 of the first housing 200 located on the right of these figures, two hinges 250 are shown.

[0074] The number of hinges 250 per pivoting wall 240 depends in particular on the length of the module 100.

[0075] Other means than a hinge 250 to allow the pivoting of the pivoting walls 240 of the first housings 200 are also conceivable.

[0076] In a preferred embodiment of a first housing 200, the bottom 210 of the first housing 200 has, on the side of the pivoting wall 240, a longitudinal rim 211 folded towards the longitudinal cavity 230 and preferably forming a C-shaped profile. In parallel, the pivoting wall 240 of said first housing has, in cross-section, a C-shaped profile, as illustrated more visibly in Figures 4 and 5. The pivoting wall 240 of said first housing is arranged so that, when said pivoting wall is in the closed position, the C-shaped profile of the pivoting wall is turned towards the longitudinal cavity 230. The pivoting wall 240 is connected to the longitudinal rim 211 of the bottom 210 of the first housing 200 by the hinges 250.

[0077] Preferably, the pivoting walls 240 of the first two housings 200 are produced for example by laser cutting then folding a sheet metal blank.

[0078] Preferably, the first housings 200 and the second housing 300 (lateral longitudinal walls, bottom) are made of metallic material. It is also possible to make them of other materials, such as for example a composite material.

[0079] In a preferred embodiment, the module 100 comprises one or more reinforcing elements 400. Each reinforcing element 400 is advantageously intended to locally reinforce the rigidity of the three longitudinal housings 200, 300, in particular to support the weight of the cables or the like.

[0080] Each reinforcing element 400 is arranged along the Y axis and preferably extends over the width 1 of the module 100.

[0081] The number of reinforcing elements 400 depends in particular on the length L of the module 100.

[0082] In the non-limiting example of Figures 1 to 3, three reinforcing elements 400 are represented per module 100. Two reinforcing elements 400 are for example arranged at the two longitudinal ends 110 of the module 100 and one reinforcing element 400 is arranged at mid-length of the module.

[0083] In one embodiment, each reinforcing element 400 has a shape adapted to match the shape of the bottom 210 of the first two housings 200, of the lateral longitudinal walls 320 and of the bottom 310 of the second housing 300.

[0084] For example, and as illustrated in Figures 1 to 3, when the bottom 210 of the first housings 200, the lateral longitudinal walls 320 and the bottom 310 of the second housing 300 form a transverse profile in the shape of a capital omega, the reinforcing elements 400 have a profile in the shape of a capital omega.

[0085] Preferably, as illustrated in Figures 1 to 5, each reinforcing element 400 has, at its two ends, a fallen edge 410. Each fallen edge 410 is directed respectively towards the longitudinal cavity 230 of a first housing 200.

[0086] Preferably, the reinforcing elements 400 are produced for example by laser cutting then folding a sheet metal blank.

[0087] Preferably, the reinforcing elements 400 are made of the same material as the three longitudinal housings 200, 300, for example a metallic material.

[0088] The reinforcing elements 400 are for example held by gluing to said longitudinal housings.

[0089] In a preferred embodiment, the module 100 comprises one or more crosspieces 500 advantageously intended for fixing said module to the ceiling 2. Each crosspiece 500 is arranged along the Y axis, and preferably extends over the width 1 of the module, between the two pivoting walls 240.

[0090] The number of crosspieces 500 depends in particular on the length L of the module.

[0091] In the non-limiting example of Figures 1 to 3, three crosspieces 500 are represented per module. Two crosspieces, called end crosspieces, are for example arranged at the two longitudinal ends 110 of the module 100 and one crosspiece, called central crosspiece, is arranged halfway along the length of the module 100.

[0092] In a preferred embodiment, the number of crosspieces 500 is equivalent to the number of reinforcing elements 400. The crosspieces 500 are preferably arranged, on the module 100, at the level of the reinforcing elements 400.

[0093] Each crosspiece 500 is fixed, for example by screwing, to the bottom 310 of the second housing 300.

[0094] Each crosspiece 500 preferably comprises through holes 520 to advantageously allow the passage of fixing elements (not shown in the figures) such as for example screws, to fix the module 100 to the ceiling 2.

[0095] Preferably, each crosspiece 500 has, at its two ends, a flanged edge 510. Each flanged edge 510 is directed respectively towards the longitudinal cavity 230 of a first housing 200. Each pivoting wall 240 of a first housing 200 rests against one of the two flanged edges 510, when the pivoting walls 240 are in the closed position. Preferably, and as illustrated in [Fig. 4], each pivoting wall 240 rests on a flanged edge 510 of a crosspiece 500, at a free longitudinal edge 241 of said pivoting wall. The free longitudinal edge 241 of a pivoting wall 240 is the longitudinal edge not connected to the bottom 210 of the first housing 200.

[0096] In a preferred embodiment, each crosspiece 500 comprises, at each flanged edge, a magnetic element 530. Each magnetic element 530 is configured to interact magnetically by attraction with a pivoting wall 240 of a first housing 200. Said magnetic elements are thus advantageously intended to retain the pivoting walls, when they are in the closed position. In this embodiment, the pivoting walls 240 are made of metallic material, such as such as steel, and the crosspieces 500 are made of non-magnetic metallic material, such as aluminum.

[0097] In an alternative embodiment, each crosspiece 500 comprises, at each flanged edge, the magnetic elements 530 are fixed to the pivoting walls 240. Each magnetic element 530 is configured to interact magnetically by attraction with a crosspiece 500, at a flanged edge. In this alternative embodiment, the crosspieces 500 are made of metallic material, such as for example steel, and the pivoting walls 240 are made of non-magnetic metallic material, such as for example aluminum. In this alternative embodiment, the magnetic elements 530 make it possible, in addition to retaining the pivoting walls when they are in the closed position, to guarantee the alignment of the pivoting walls 240.

[0098] In the configuration where the module 100 is fixed directly to the ceiling 2, each crosspiece 500 can have a flat profile.

[0099] In the configuration where the module 100 is fixed to the ceiling 2 via the longitudinal beam 3, as illustrated in [Fig.4], each crosspiece 500 has an inverted capital omega profile. Each crosspiece 500 comprises a central web 540, extended on either side by a so-called bent part 550, itself extended by a wing 560. The wings 560 of each crosspiece 500 are preferably coplanar and extend in a plane parallel to that of the central web 540. The concavity of the omega (i.e. the space between the central web 540 and the bent parts 550 of the crosspiece 500) of each crosspiece 500 is intended to receive the longitudinal beam 2. The wings 560 of each crosspiece 500 are intended to be fixed to the ceiling 2 and the bent parts 550 are intended to be fixed to the longitudinal beam 3. The wings 560 of each crosspiece preferably comprise through holes to advantageously allow the passage of fixing elements such as for example screws, to fix the module 100 to the ceiling 2. The bent parts 550 of the crosspiece 500 comprise through holes to advantageously allow the passage of fixing elements such as for example screws, to fix the module 100 to the longitudinal beam 3. In this configuration, the pivoting walls 240 then have a height such that they take into account both the height of the second housing 300 and the height of the longitudinal beam 3.

[0100] In a preferred embodiment, each first housing 200 may comprise a locking mechanism 260 for locking the pivoting door 240 in the closed position.

[0101] In a preferred embodiment of a locking mechanism 260, as illustrated in Figures 4 and 5, the locking mechanism 260 may comprise a lock 261 with a cam 262. The lock 261 with a cam 262 is preferably fixed on the pivoting wall 240 of the first housing 200. The lock 261 with a cam 262 is arranged so that the cam 262 can engage behind the fallen edge 510 of one of the crosspieces 500 of the module 100 to lock the pivoting wall 240 in the closed position. In the non-limiting example of figures 2 to 5, the lock 261 with a cam 262 is arranged at the central crosspiece 500 so that the cam 262 can engage behind the fallen edge 510 of the central crosspiece 500. The unlocking of the pivoting wall 240, and consequently the possibility, for a user, of pivoting the pivoting wall 240 from the closed position to the open position, can be achieved for example by means of a key (not shown) corresponding to this lock 261.

[0102] The lock 261 with a cam 262 is arranged, when the pivoting wall 240 is in the closed position, on the side of the longitudinal cavity 230 of the first housing 200.

[0103] In this case, and as illustrated in Figures 1 and 8, the pivoting wall 240 includes a light 242 opposite the lock 261 to allow access of the key to said lock.

[0104] In a preferred embodiment, each pivoting wall 240 of a first housing 200 may comprise, at its free longitudinal edge 241, one or more notches 243. Each notch 243 is sized to allow the introduction of a user's finger, in order to be able to pull on the pivoting wall 240 in order to move it from the closed position to the open position and to access the longitudinal cavity 230 of said first housing. This action (moving from the closed position to the open position) is only possible once the pivoting wall 240 has been unlocked.

[0105] In the non-limiting example of Figures 1 to 3, each pivoting wall 240 has two notches 243.

[0106] In one embodiment, the module 100 comprises, at each first housing 200, one or more tilting latches 600 arranged to limit the deflection of the bottom 210 of the first housing 200 under the effect of the weight of the cables and the like. Each tilting latch 600 is advantageously intended to reversibly connect the bottom 210 of a first housing 200 and a crosspiece 500, preferably at one end of said crosspiece.

[0107] The number of tilting latches 600 corresponds to twice the number of crosspieces 500. Thus, in the example illustrated in FIGS. 1 to 3, three tilting latches 600 are represented per first housing 200, one for each crosspiece 500.

[0108] In one embodiment, as illustrated in Figures 6 and 7, each tilting latch 600 comprises an arm 610 and a hook 620. The arm 610 is hinged at a first end and is provided, at a second end, with the hook 620. In [Fig.6], which is a side view of the module, the pivoting wall 240 of the first housing 200 is transparent and shown in dotted lines, to highlight the three tilting latches 600.

[0109] The arm 610 is connected, at the first end, to the bottom 210 of the first housing 200. Preferably, the arm 610 is connected to the fallen edge 410 of a reinforcing element 400.

[0110] The arm 610 is rotatable about an axis parallel to the Y axis, as illustrated in Figures 2 and 3.

[0111] The hook 620 is intended to engage in a notch 571 made in a rim portion 570 of the associated crosspiece 500, said rim portion 570 being made close to the end of said crosspiece, and therefore close to the dropped edge 510.

[0112] Each tilting latch 600 moves between a locking position and a tilted position.

[0113] In the locking position, as illustrated in [Fig.2], the tilting latch 600 extends between the bottom 210 of the first housing 200 and the crosspiece 500, substantially along the Z axis. In this locking position, the arm 610 is connected to the bottom 210 of the first housing 200 and the hook 620 is engaged in the notch 571. The tilting latch 600 locally blocks access to the longitudinal cavity 230 of the first housing 200.

[0114] In the tilted position, as illustrated in [Fig.3], the tilting latch 600 is configured to allow full access to the longitudinal cavity 230 of the first housing 200, facilitating the installation of cables along the entire length of the module. In this tilted position, the tilting latch 600 is no longer connected to the crosspiece 500. The hook 620 is removed from the notch 571, the tilting latch 600 is tilted towards the bottom 210 of the first housing 200, after a rotation of substantially 90°, around an axis parallel to the Y axis.

[0115] In an exemplary embodiment, each tilting latch 600 is fixed to the fallen edge 410 of the reinforcing element 400 by a clamping element 630 to prevent the tilting latch 600 from rotating. The tilting latch 600 and the fallen edge 410 of the reinforcing element 400 comprise passage holes for the clamping element.

[0116] In one embodiment, the clamping element 630 is of the bolt type (i.e., a screw and nut assembly), for example, a bolt with a round head and a square neck (known by the acronym TRCC bolt). The TRCC bolt is located in the axis of rotation of the tilting latch 600. The TRCC bolt is arranged so that the head of the screw is disposed on the side of the longitudinal cavity 230 of the first housing 200. The passage holes of the tilting latch and the flanged edge of the reinforcing element have a square section sized to cooperate with the TRCC bolt. This geometric shape is intended to keep the head of the screw in the locked position during the tightening, avoiding the use of an additional tool to hold the screw head in position while tightening the nut.

[0117] When the tilting latch 600 is in the locked position, the nut is tightened so that the square neck of the screw is in the holes of the tilting latch 600 and the flanged edge 410 of the reinforcing element 400.

[0118] To move from the locking position to the tilted position, the nut of the TRCC bolt is loosened until the square collar is disengaged from the holes of the tilting latch 600 and the flanged edge 410 of the reinforcing element 400, detaching the tilting latch 600 from the flanged edge 410 of the reinforcing element 400, and thus allowing said tilting latch to pivot to the tilted position, by rotation.

[0119] In a preferred embodiment, each first housing 200 comprises an element 270 promoting the attachment of cables and the like in its longitudinal cavity 230.

[0120] In embodiments, as illustrated in Figures 2 and 3, the element 270 is a perforated sheet or a welded wire mesh, having, in cross section, a C-shaped profile, with the two edges of the C-shaped profile resting on the bottom of the first housing. The element 270 is assembled to the bottom of the first housing, via the two edges of the C-shaped profile, for example by gluing. Thus, the element 270 makes it possible to fix the cables in the longitudinal cavity 230 of the first housing 200, using cable ties, also called “colson”, “rilsan” or “ty-rap®” collars (not shown in the figures).

[0121] In a preferred embodiment, as illustrated in [Fig.4], the module 100 comprises, in the second housing 300, at least one fixing system 700 for a lighting system 750.

[0122] The fixing system 700 is adapted to the type of lighting 750 to be installed.

[0123] In one embodiment, as illustrated in [Fig. 10], the lighting 750 is lighting of the fluorescent tube, neon tube, or even LED tube type, without this being limiting of the invention.

[0124] In a preferred embodiment, the module 100 comprises, at each longitudinal lateral wall 320 of the second housing 300, at least one opening 340 to allow access, from each first housing 200, to said second housing.

[0125] An opening 340 is advantageously arranged at the level of each fixing system 700. There are therefore as many openings 340 in each lateral longitudinal wall 320 of the second housing 300 as there are fixing systems 700 in the second housing 300. Each opening 340 thus advantageously allows the passage of the electrical cables for supplying the lighting 750.

[0126] In a preferred embodiment, as illustrated in [Fig. 8], the module 100 comprises, at one of these longitudinal ends 110, a lateral cap 800. Such a lateral cap 800 is intended to close the longitudinal end 110 of the module 100 and to prevent access to the interior of the first housings 200, when the module 100 is in place on the ceiling 2, and its longitudinal end 110 is not attached to a wall, nor connected to another module. The module with a lateral cap 800 is a so-called end module.

[0127] The side cap 800 is fixed to a longitudinal end 110 of the module 100, preferably by welding.

[0128] The module 100 is configured to be assembled with a plurality of other modules 100 to form an assembly 1.

[0129] In an exemplary embodiment, as illustrated in Figures 1 to 3, to assemble two successive modules 100 and ensure the alignment of the modules with each other, each module 100 comprises, at only one of its two longitudinal ends 110, a union connector 900.

[0130] In an exemplary embodiment, the union connector 900 is a straight union connector. Such a straight union connector advantageously makes it possible to assemble two modules 100 end to end, that is to say longitudinally, by connecting the longitudinal ends 110 of the modules 100. The axes X of each module 100 are then merged.

[0131] The straight union connector is for example in the form of a part having a shape adapted to match the shape of the bottom 210 of the first housings 200, the longitudinal lateral walls 320, 340 and the bottom 310 of the second housing 300.

[0132] For example, and as illustrated in Figures 1 to 3, when the bottom 210 of the first housings 200, the lateral longitudinal walls 320, 340 and the bottom 310 of the second housing 300 form a transverse profile in the shape of a capital omega, the straight union connector 900 has a profile in the shape of a capital omega.

[0133] The straight union fitting 900 is assembled, in part, to one of the longitudinal ends 110 of the module 100, and extends beyond the longitudinal end of said module.

[0134] The straight union connector 900 is preferably assembled by gluing to one of the longitudinal ends 110 of the module 100.

[0135] When assembling the module 100 with another module 100, the two modules 100 are joined together, at one of their ends 110, and the straight union connector 900 of one of the modules 100 ensures the connection with the other module 100, guaranteeing the alignment between said two modules.

[0136] As a non-limiting illustrative example, Figures 9 and 10 illustrate, in top view and in bottom view, an assembly 1 comprising two modules 100 assembled at their longitudinal ends 110.

[0137] The assembly of several successive modules one after the other advantageously makes it possible to create both two cable paths and continuous lighting along the entire length of the corridor or tunnel. Once all the modules are fixed to the ceiling, the user only has to place all the tilting latches of each module in the tilted position to fully access the longitudinal cavities of said modules, without the slightest hindrance, and install the cables and the like in these longitudinal cavities.
