Advantageously, the movement between the fixed modules 12 and the mobile part 20 is limited; in particular, it is advantageous that only a rotation of approximately 90 ° is possible, and a system of stops is put in place. Furthermore, it is advantageous to provide a positive locking of the intermediate portion 20 relative to the mounting modules 12 in the second position, so as to give full latitude in the establishment of the front plate 6 by releasing both hands; in addition, it may also be advantageous to provide a positive locking of the intermediate portion 20 relative to the mounting modules 12 in the first position, so as to stabilize the assembly.

In particular, and as illustrated in FIG. 2B, if the first position is such that the branch 22 is in vertical unstable equilibrium, with the opposite end 30 to the coupling means 26 above said means 26, one of the mounting modules 12 and at least the corresponding branch 22 may comprise a latching system 32, 34 which can be manually deactivated. As regards the locking in a second horizontal position, the mounting module 12 comprises guide means 36 provided with a limit stop 38 cooperating with an arrangement of the branch 22 when the guided part 2691 LPu has made 90 ° so as to counter the effect of gravity. Any other alternative is possible.

The intermediate portion 20 may be unitary, with a receptacle 40 molded integrally between the branches 22, eccentric relative to the pivot, in particular at the opposite end 30, and connecting them. Advantageously, the receptacle 40 driven directly by the branches 22 is secured to them fixedly but can be separated. In particular, the branches 22 comprise, at their end 30 opposite to the pivoting coupling means 26, means for securing the receptacle 40, for example grooves 42 with the possibility of latching. The receptacle 40 meanwhile, of substantially rectangular shape whose long side is intended to be parallel to the rail 2 and the apparatus 4, comprises complementary securing means at its ends, in particular a protrusion 44 slidable in the groove 42.

The receptacle 40 may be of predetermined fixed length L, for example the length of a mounting rail 2 in a standard cabinet 1. Depending on the configuration of the installation, it may be preferable to adapt to the actual distance covered. by the devices 4 mounted on the rail 2, for example to limit the size of the recess 8; it is then advantageous to have a receptacle 40 of length L adaptable, in order to delay the choice of the necessary length. In one option, the receptacle 40 may be a plastic blade for breakable labels in length (Figure 2B); in a preferred option illustrated in Figure 2A, the receptacle 40 may comprise two parts 40A, 40B telescopic relative to each other which allows to adapt to a modification of the installation.

The receptacle 40 is of configuration adapted to the selected communication means. In the embodiment illustrated in Figure 2B, the receptacle comprises a simple strip of plastic, in or on which can be placed identification tags 4 adjacent devices. The receptacle 40 may furthermore be equipped with luminous means, such as bistable displays or light-emitting diodes (LEDs), making it possible to provide reactive information; according to the embodiment illustrated in FIGS. 4, a screen 46 of liquid crystal type is associated with the receptacle 40 and makes it possible to scroll and / or update information. All optical viewing means requiring 2691 LPu energy can be powered by a battery, the receptacle 40 then comprising a suitable housing. It is also possible for the screen 46 or the LEDs to be connected directly to the network, the receptacle 40 then comprising passages for the supply wires. In this option, it is advantageous that the branches 22 and the mounting modules 12 are also provided with this type of arrangement within their housing, as well as, for example, at the pivoting coupling means 24, 26. to direct the wires towards the inside of the cabinet 1. In this way, the supply wires remain invisible and protected, as well as perfectly localized, so that the internal dimensions of the cabinet 1 are limited and the risks less damage.

In an advantageous embodiment shown diagrammatically in FIG. 2A, the receptacle 40 can be used for means of communication with or between the electrical devices 4. In particular, if the apparatuses 4 are provided with radiofrequency type transmitters / receivers, for example an RFID RFID tag, the receptacle 40 may include one or more antennas 48 for wireless communication with the devices 4 that will be adjacent to it. Here again, preferably, the antennas 48 are integrated into the housings of the mounting and coupling elements 12, 22, 24, 26 for functional and aesthetic reasons.

Other alternatives for the means of communication are conceivable. Furthermore, it is possible for the receptacle 40 to comprise both an RFID antenna 48 and a direct identification system for the user. If the number of functions to integrate is important, it may be interesting that the device 10 ', 10 "according to the invention comprises two receptacles 40, 40', similar or different, in particular, according to an embodiment illustrated in FIG. , the end modules 12 'comprise securing means 24, 24' on each side of the nose 18, so as to be able to couple a receptacle 40 upwards and a receptacle 40 'downwards, for example an LCD screen in top and an antenna at the bottom, the two receptacles 40, 40 'then having symmetrical movements during their passage from one position to another.In this option, it may be advantageous to provide coupling means 24, 24' such that one of the receptacles 40 ', particularly when it is an antenna, always remains behind the plastron 6 in the first position 2691 LPu: thus, as shown in Figure 3A, the first means of fastening 24 are located on the nose 18 of the module 12 ', the second 24' being behind.

In one embodiment illustrated in FIG. 3B, to simplify the passage from the first to the second position, and vice versa, two receptacles 40, 40 'placed on the same mounting modules 12 ", the coupling means 24" may include a chisel type system, so that the two receptacles 40, 40 'are operable simultaneously.

When carrying out the electrical installation, a table 1 with rails 2 of conventional type is used, and the design of the installation and the mounting of the devices 4 as such are not modified. As required, on a rail 2, a device 10 according to the invention is integrated, with the mounting modules 12 on either side of a juxtaposition of electrical devices 4: FIG. 4A. It is possible to assemble the communication support device 10 prior to placement on the rail 2 (FIG. 2B), in particular in the case where internal wire connections are present; for a simpler device 10, it is possible to set up the mounting modules 12 within the row and to finalize the coupling of the intermediate portion 20 later. Whatever the option, the mounting of the modules 12 is direct, similar to that of the devices 4. Depending on the installation and the communication requirements, it is possible to place two devices 10 according to the invention on the same row, for example. example if communicating devices are located on a first part and if equipment for which an LCD screen is preferred are on a second part.

The receptacles 40 are initially placed in their first position so as to verify the installation, possibly set up the labels corresponding to the devices 4, test the RFID communications, and / or other conventional operations (Figure 4A). When the installation and verification of Table 1 are completed, the receptacles 40 are moved to their second position, substantially normal to the bottom wall of the mounting modules 12 (Figure 4B); this movement can be achieved by direct gripping on a receptacle 40, optionally provided with a gripping protrusion, or any other alternative. In this second position, a plastron 6 can be placed on the rows of apparatus 4, by passing the receptacle 40 and the branches 22 in the recess 8; preferably, the length of the recess 8 of the plastron 6 and the length L of the intermediate portion 20 are adapted so that the branches 22 of the device abut the edges of the recess 8 so that the aesthetic and protective aspects are optimal . Once the front plate 6 is put in place (FIG. 4C), the receptacle 40 is returned to the first position, so that the information is visible and the actuating levers of the apparatuses 4 are accessible (FIG. 4D). In case of maintenance, to remove the front plate, the same maneuver is performed.

Thus, the communication support device 10 according to the invention allows access to the information it contains with and without front panel 6; it is installed in the universal boards 1 on the same rails 2, in particular DIN, mounting that the modular electrical devices 4; Table 1 itself can be provided with or without faceplates 6, the device 10 according to the invention also making it possible to protect the connection terminals of the electrical devices 4 when the receptacle (s) is (are) in the first position. What is more, the device 10 is independent of the front plate 6 but also the apparatus, which allows a modification of each of these elements 4, 6 easily; in particular, when the device 10 is in its first position parallel to the mounting wall, it is possible to remove or add an electrical device 4 on the rail 2. Moreover, by the integration of an antenna 48, the device 10 can relay information from an RFID type communication system, which can be tested without, and used with, plastron 6, without loss of information and communication.

Although the invention has been described with reference to a device for carrying information relating to the assignment of an electrical protection device in a cabinet, it is not limited thereto: other elements may be affected by the invention, as in particular the electrical boxes or envelopes containing electronic equipment of type for example telephone splitter. Furthermore, although described in combination, the various elements constituting the preferred embodiment according to the invention can be used separately or with equivalent alternative elements.
