DESCRIPTION OF PARTICULAR EMBODIMENTS

Figures IA and IB show an embodiment of the invention. They show an enclosure 2 of a supply module 1, intended to be arranged in a part of a housing. The enclosure is parallelepipedic. It comprises: a proximal lateral face 10 and a distal lateral face 20; an upper face 30 and a lower face 40, the lower face being intended to be deposited on a horizontal flat surface forming a floor of a housing; a rear face 50 and a front face 60, the rear face being intended to be applied against a vertical flat surface forming a partition of a housing.

The proximal lateral face, the distal lateral face, the upper face and the front face generally take the form of a wall, for example a solid wall, having openings as described below, these openings allowing the passage of electrical or fluidic utilities. The lower face 40 and the rear face 50 may be hollow.

There is shown an orthogonal coordinate system having three axes x, y, z, the xy plane being a horizontal plane and the xz and yz planes being vertical planes. The xy plane is a lateral plane while the yz plane is a longitudinal plane. The x axis is a transverse axis, according to which the chamber 2 extends along a width. The y axis is a longitudinal axis, according to which the chamber 2 extends along a length. The z axis is a vertical axis, according to which the enclosure 2 extends according to a height. The height of the enclosure is 2 preferably between 30 cm and 1 m. The length of the chamber 2 is preferably between 50 cm and 150 cm, while the width of the chamber 2 is preferably between 5 cm and 30 cm. The width of the enclosure is generally less than its height and length. The length of the enclosure is generally greater than its height and its width.

The parallelepipedal geometry of the enclosure corresponds to a preferred embodiment because it facilitates the juxtaposition of adjacent modules as described in connection with Figure 3 described below.

Each side face of the enclosure preferably comprises a plurality of openings, each opening allowing the passage of electrical cables or the passage of a fluid, that is to say the passage of electrical and / or fluidic utilities. The fluid may be water intended to supply water to the housing in which the module is placed. It may also be waste water from the housing and intended to be evacuated from the housing. It may also be supply air intended to be injected into the housing. This air may have been previously heated or cooled, the supply then forming a heating or air conditioning. It may also be an air intended to be evacuated from the housing to the outside, so as to allow ventilation of the housing. It may also be an air pumped or injected into each chamber 2, so as to avoid condensation on conduits, extending into the enclosure. The electric cables or the fluids are intended to circulate along a longitudinal axis of the enclosure, between the proximal lateral face 10 and the distal lateral face 20 of the enclosure 2.

In FIG. 1A, there is shown a first proximal opening 11 formed in the proximal lateral face 10 and a first distal opening 21 formed in the distal lateral face 20. Each opening allows an electrical conduit 101 shown in FIG. IB, to open respectively at the proximal lateral face 10 and the distal lateral face 20. The electrical conduit comprises at least one electrical cable extending between the proximal lateral face and the distal lateral face. a second proximal opening 12 formed in the proximal lateral face 10 and a second distal opening 22 formed in the distal lateral face 20. Each opening allows a fluid supply conduit 102 shown in FIG. respectively at the proximal lateral surface 10 and the distal side wall 20. a third proximal opening 13 formed in the proximal lateral face 10 and a third distal opening 23 formed in the distal lateral face 20. Each opening allows a fluid flow conduit 103, shown in FIG. 1B, to open respectively at the level of the proximal lateral face 10 and the distal lateral face 20. a fourth proximal opening 14, formed in the proximal lateral face 10 and a fourth distal opening 24, formed in the distal lateral face 20. Each opening allows a fluid duct 104 of alimentat ion or air discharge shown in Figure IB, to open respectively at the proximal side face 10 and the distal side face 20. In this example, this conduit allows the supply of heated air or cooled the room in which the module is arranged.

Preferably, the openings in the same side face are aligned along an axis Δ. The chamber 2 may comprise an internal partition, extending between the proximal lateral face 10 and the distal lateral face 20, for example substantially parallel to the lower face 40. This partition makes it possible to isolate the electrical conduit 101 from screw of a possible liquid present in the chamber 2, for example from the fluid supply conduit 102.

Furthermore, a module is intended to be juxtaposed with another module, so as to allow the supply of electricity, water, possibly air a housing and the evacuation of water, and possibly air d 'housing. In order to facilitate an electrical or fluidic connection of the conduits extending into a module, the respective positions of the first proximal opening 11, the second proximal opening 12, and the possible fourth proximal opening 14, on the first lateral face 10, are identical to the positions of the first distal opening 22, the second distal opening 22 and the possible fourth distal opening 24 on the second lateral face 20. The position of the third proximal opening 13, intended for the evacuation of a wastewater may be slightly shifted towards the lower part 40 relative to the position of the third distal opening 23, so as to allow an inclination of the water discharge conduit 103. Such an inclination allows a gravity flow waste water.

In addition to the supply or discharge function in fluids (air or water), the module 1 also has the function of distributing a power supply or a fluid in a room in which it is arranged. For this, an enclosure has a face, called connection face, in which are provided so-called functional openings for the supply of water or electricity. Preferably, the functional openings are formed in the same connection face, with the exception of a functional discharge opening, intended to collect wastewater, the latter being able to be formed in the front face 60, as described hereinabove. after in connection with Figure IC. Maximizing the number of functional openings on the same connection face reduces the cost of manufacture.

FIG. 1A represents a preferred case, in which the connection face corresponds to the upper face 30 of the enclosure 2 of the module. In this figure, there is shown: a functional power supply opening 31i, in which is provided an electrical outlet. Preferably, the electrical outlet is flush with the surface defined by the upper face 30 so as to facilitate connection to electrical equipment. The electrical outlet is therefore integrated into the enclosure 2. The electrical outlet is connected to the electrical supply duct 101, via a conductive harness 71. This electrical outlet can be a socket intended to provide a power supply or a socket for an electrical communication, eg ethernet network socket, or telephone socket. According to one embodiment, the module comprises a plurality of electrical functional openings, comprising different types of electrical connections for powering the electrical connection network or a communication network. Each functional feed opening can be closed by a removable window. a functional lighting opening 312, in which is provided a light source 111, or a connection adapted to receive a bulb. In this case, a switch 111 'allows the activation of the light source. The switch may be disposed at the connection face. The functional lighting opening can be closed by a removable transparent window, which allows a replacement of the light source. The functional lighting opening is connected to the electrical supply duct 101 by an electrical harness 71. A functional water supply opening 32, connected to the water supply duct 102 by a supply tube 72. opening is intended to be connected to a supply pipe of a faucet. The module may comprise two water supply conduits 102, one for a cold water supply and the other for a hot water supply, in which case the module may comprise two functional water supply openings 32, respectively connected to the supply ducts by a supply tube 72. Each functional supply opening 32 can be closed by a removable shutter, a functional water discharge opening 33, connected to the exhaust duct of water 103 by a discharge tube 73. The functional discharge opening may be formed in the connection face, in this case the upper face 30, as shown in Figures IA and IB, or in the front face 60 , and in particular near the lower face 40, as shown in FIG. In the latter case, the functional discharge opening is designated by the reference 63 '. By close, means closer to the lower face 40 than the upper face 30. Such an arrangement facilitates a connection with a shower or a bath, the water evacuations taking place close to the ground. Note that a module may include a water discharge opening 33 formed in the upper face 30 of the enclosure and a water discharge opening 63 'formed in the front face 60, which allows to be connected to a sink or sink, through the opening 33, or to a shower or bath, through the opening 63 '. The unconnected drain openings can be closed with a removable shutter. a functional air supply opening 34, connected to the air supply duct 104 by an air supply tube 74. In this example, the air supply opening comprises a protective grille. As previously mentioned, the air supply duct may be able to bring hot air or cold air.

The module may include a functional air exhaust opening, connected to an air exhaust duct. The latter is then connected to a fifth proximal opening 15 on the first lateral face 10 and a fifth distal opening 25 on the second lateral face 20. This allows an evacuation of the air, thus ensuring ventilation of the room in which is placed the module. The air discharge openings 15 and 25 are shown in Figures 2A to 2D.

Alternatively, the proximal and distal lateral faces do not respectively comprise a fourth proximal opening and a fourth distal opening, intended for supplying air. The chamber 2 may then comprise a heating or air conditioning element, the latter communicating with the functional air supply opening 34 opening from the connection face. The heating or cooling element can be activated by a switch disposed on the connection face.

The connection face can be formed of a removable shutter, which allows its cleaning. Alternatively or additionally, the functional air exhaust opening and / or the air supply functional opening 34 may be removable, to allow replacement or cleaning.

The connection face can also be the front face 60. This case is adapted to an integration of the module in a wall, as described later in connection with FIG.

The first lateral face 10 and the second lateral face 20 may each comprise an air opening 16, 26, called sixth openings, allowing air to circulate inside the enclosure. A sixth proximal ventilation opening 16 is then formed in the first lateral face 10 and a sixth lateral ventilation opening 26 is formed in the second lateral face 20, vis-à-vis a first proximal opening of aeration an adjacent module. This allows a circulation of air inside each chamber 2, so as to prevent any formation of liquid by condensation on a fluidic conduit, in particular on the fluidic conduit 102 for supplying water. Ventilation apertures 16 and 26 are shown in Figures 2A to 2D.

According to a variant, shown in FIG. 1D, the second lateral face 20 has no distal openings, the latter being formed in the front face 60. Such a variant is adapted to the arrangement of modules in a corner of the room , so that the distal openings in the front face can be disposed opposite proximal openings in a first side face of another orthogonally disposed module, whose longitudinal axis extends along the y axis. In FIG. 1D, there is a first distal opening 61, a second distal opening 62, a third distal opening 63 and a fourth distal opening 64. The openings opening on the front face 60 are preferably aligned along a vertical axis Δ '. Each duct 101, 102, 103, 104 forms a bend inside the enclosure so as to open at a distal opening.

As previously described, it is preferable that the water discharge duct 103 is inclined relative to the horizontal, to allow a gravity flow of waste water. Thus, the water discharge conduit 103 opens, at the second lateral face 20, at a distance, vis-à-vis the lower face 40, greater than the distance at which it opens at the level of the first This allows a spontaneous flow of wastewater between the second lateral face and the first lateral face. The module may comprise an adjustment system, making it possible to easily adjust the position of the evacuation duct 103, taking account of the fact that several adjacent modules may be juxtaposed two by two, and that the evacuation ducts thus juxtaposed must preferably define a slope, if possible regular, and preferably greater than 1 cm per meter, and preferably greater than 3 cm per meter.

In Figures 2A and 2B, there is shown a first example of adjusting the position of the exhaust duct. The chamber 2 of the module comprises a plurality of third proximal openings 13i, 132, 133, 134, 135 and a plurality of third distal openings 23i, 232, 233, 234, 235, the latter being respectively at the same distance, vis-à-vis -vis the lower surface 20, that the first proximal openings 13i, 132, 133, 134, 135. On a first module 1, the exhaust duct 103 may extend between the openings 13i and 232. On a second module Γ, attached to the first module 1, the exhaust duct 103 'can extend between the openings 132 and 233, etc. A third module 1 ", attached to the second module Γ, the exhaust duct 103" can be extend between openings 133 and 234 etc.

According to a variant shown in Figures 2C and 2D, there is shown a second example of adjusting the position of the exhaust duct. In this example, the third proximal and distal openings are of oblong shape, so that the exhaust duct 103 can be translated, along the vertical axis z, through each opening. A locking member blocks the duct at each opening, adjusting its inclination relative to the horizontal direction.

The adjustment of the position and the inclination of the water discharge duct makes it possible to adapt the position of the latter according to the position of the module relative to other modules, so as to adjust an inclination of the duct. all the water evacuation ducts and juxtaposed.

FIG. 3 shows a series of modules Γ, 1 ", Γ", 14 joined to each other by their respective lateral faces, the rear face 50 of each module being applied against a partition of the part, the lower face 40 of each module resting on the ground. Such an assembly makes it possible to easily equip a room, by providing utilities of the electric current type, water, air in different parts of the room, along the walls of the latter. The connection between two adjacent power supply conduits can be made by arranging electrical connectors at each first opening. The connection between two adjacent fluid ducts may be effected by means of a sleeve penetrating into each duct, or by a connection between a male fluid duct and a female fluid duct. Thus, each fluid conduit opening from the first side face 10 may be a male conduit, while each fluid conduit opening from the second side face 20 may be a female conduit. It will be understood that the functional openings of each module are not all systematically operational. Some modules may have only their functional fluidic openings activated, others having only their activated electrical functional openings. The fact of juxtaposing identical modules, having both functional electrical or fluidic openings, is however an economical solution, allowing to have an evolutionary configuration. Alternatively, the modules may have different lengths, and preferably multiple lengths of a base, for example 60cm - 120 cm - 180 cm - 240 cm, the base length being in this example 60 cm.

The first ventilation aperture 16 of the first module 1 can be connected to a pump, so as to allow aeration of the modules of the series, through the sixth openings 16 and 26 of the respective proximal and distal lateral faces.

Figure 4 shows a use of a light source 111 fitted to a module. The light source emits an incident light beam L along a vertical axis. This light source can be pre-installed. Alternatively, the functional lighting opening 312 includes a socket for connecting a bulb. The lighting of the room is therefore indirect. The module may comprise an inclined reflecting element, the inclination being variable relative to the vertical axis z, this element comprising for example a reflective surface of a prism or a mirror 3, for reflecting light towards the room in which the module is arranged. This provides a reflected Lr direct lighting. The reflecting element may also or alternatively comprise a light diffuser, for backscattering the incident light to the room. The invention can be implemented in prefabricated housing for temporary housing, or during the renovation of cheaper premises, for use in housing or offices. It can also be implemented during the manufacture of a home. In such a case, a housing L is advantageously formed in a wall M manufactured, so as to accommodate each enclosure 2. Preferably, the dimensions of the housing are adapted to the dimensions of the enclosure 2 so as to allow the integration of this last, so that the front face 60 extends in the extension of the wall defined by the wall M. In such a configuration, the connection face is formed in the front face 60, the latter having a better accessibility. Figure 5 shows such a configuration. The invention can be used during the construction or renovation of homes, so as to allow a fast, simple and inexpensive connection to networks of utility type network, water distribution network or air , or sewage system.
