As mentioned above, the subject of the invention is a transportable construction of the caravan or mobile home type. This transportable construction 1 comprises a base cell 2 mounted on a carrier chassis 24, here equipped with two axles arranged side by side.

The construction 1 further comprises a device 26 for converting wind energy into energy of another nature, in particular mechanical or electronic. The conversion device 26 comprises a wind turbine 27 comprising a rotor 28 and a stator 29. The conversion device 26 further comprises a converter 30 of the mechanical rotational energy of the rotor 28 of the wind turbine 27 into an energy of another nature, namely here an electrical energy, the converter 30 being formed by a generator of electricity known per se. The wind turbine 27 is a vertical axis wind turbine with a Savonius type rotor 28 and a stator 29 supporting the rotor 28, possibly at least partially surrounding it. The conversion device 26 further comprises a sleeve 36 for receiving the wind turbine which extends, in the configuration of use of the device, in the erected state, with at least its open upper end and the controlled means 38 of the wind turbine. sliding drive of the wind turbine 27 between a position retracted into the sheath 36 and an extended position of said sheath 36 in which said wind turbine 27 is at least partially projecting from the upper end of the sheath 36.

In the example shown in Figure 11, the stator 29 is in the form of a frame which comprises two longitudinal members 44A and here, three cross members connecting said longitudinal members 44A therebetween.

In the example shown in FIG. 10, the stator 29 is in the form of a support module block of the rotor 28, the longitudinal sides of the module block which extend parallel to the longitudinal axis of the sleeve 36 being represented at 44B. to the figures.

The rotor 28 comprises a rotary axis 51 parallel to the longitudinal axis of the sleeve 36. In the example of FIG. 11, the rotary axis 51 extends between two crosspieces of the stator frame, interconnecting them said sleepers. The rotor 28 further comprises two semi-cylindrical blades 52 coupled by their longitudinal edge formed by a generatrix of the cylinder to said axis 51. This rotor is made of metal, like the stator. The blades and the rotor axis are housed inside the frame in the case of a frame-shaped stator and above the module block in the case of a block-shaped stator.

To allow the passage of the wind turbine from a retracted position to an extended position of the sleeve 36 or vice versa, the means 38 for driving in sliding displacement of the wind turbine comprise a longitudinal guide path 40 formed by two parallel rails. look, arranged inside the sheath. These rails engage with complementary guide means 41 arranged along the longitudinal members of the frame or the longitudinal sides of the constituent module block of the stator. These complementary guiding means may also be formed by rails or rollers or rollers.

A moving drive assembly of the stator 29 along the guide path 40 of the sheath is provided. This assembly is a screw 42 / nut 43. The nut 43 of this screw / nut assembly is fixedly arranged in rotation at the stator, for example, of a cross member, in this case the bottom cross member. of the constituting frame of the stator, while the screw 42, which passes through said nut 43, extends inside the sleeve 36 axially fixed in a direction parallel to the longitudinal axis of the sheath 36, and is driven in rotation by an electric motor 53 disposed at the lower end of said screw.

The device further comprises an accumulator 48 of the energy produced by the energy converter 30 formed for example by one or more batteries. The means 39 for controlling the drive means 38 for moving the wind turbine comprise, for their part, a control unit 45A, means 46 for determining data representative of the meteorological conditions, able to deliver said data to the unit 45A. control unit and data input supply means 47 capable of supplying input data to said control unit 45A. These control means 39 further comprise a control unit 45B, data input supply means 50 capable of supplying input data to said control unit 45B, and means 49 for determining data representative of the level. charging the accumulator 48 capable of delivering said data to the control unit 45B. In the example shown, the control unit 45A and the control unit 45B are common and form a single control unit configured to control the drive means 38 for sliding movement of the wind turbine 27 in function. data provided by the data determination means 49 and 46 and the data delivery means 50, 47.

In the example shown, the means 46 for determining data representative of the meteorological conditions comprise an anemometer and the means 49 for determining data representative of the charge level of the accumulator 48 comprise a charge sensor of said accumulator. The control unit, common to all means of supply and determination of data, comprises, meanwhile, means for electronic processing and / or data processing, such as a microprocessor associated with a working memory . The data input supply means 47 or 50 can comprise data acquisition means and / or a data entry interface also called human / machine interface and / or a predefined data storage memory.

In the example shown, the data input supply means 47 and 50 are common and are formed by a remote control type interface and / or touch screen and / or keyboard. From said input data and the data provided by the data determination means 49, 46, the control unit is thus configured to operate the motor 53 for rotating the screw 42 of the assembly in operation. screw 42 / nut 43, for a movement up and down of the wind turbine 27 in the direction of an input or an output of said sleeve 36. The expression "the control unit is configured for" means that the microprocessor includes instructions for performing the action.

The operation of such a power conversion device 26 is extremely simple: according to the data provided by the data determination means 49 and 46 above and other input data or inputs through the interface, the control unit in operation operates the drive motor in rotation of the worm in one direction of rotation or in the other, depending on the desired up and down movement of the wind turbine.

As mentioned above, the control unit may comprise data processing means preventing the output of the wind turbine in the event of excessive wind, even in the case of a low charge level of the accumulator.

For optimum operation and minimal size of the energy conversion device as described above, the wind turbine 27 and the sleeve 36 are positioned at least partially above the hitching means. Thus, the sheath 36 rests at its lower end on the branches of the V coated constituting the drawbar while the rotor of the wind turbine extends in line with the space left free between the branches of the V drawbar hitch. It is thus possible, if necessary, to allow the wind turbine, in the lower position, to protrude from the underside of the drawbar by crossing the space between the branches of the V. In the up position, the wind turbine s extends at least partially above the ceiling level 5 of the base cell 2. In the example shown, the sheath is attached to the front wall 4 of the base cell 2. Thus, in transport configuration of the construction, the wind turbine is in the low position and protected by the sleeve while in configuration of use of the construction, the wind turbine can be more or less out of the sheath according to the meteorological conditions and energy needs.

In the example shown, the habitable volume of the building can be increased. For this purpose, one of the longitudinal side walls 3 of the base cell 2 is doubled externally by a foldable structure 7. This foldable structure 7 comprises a floor 8, a longitudinal side face 9, a ceiling 10 and two cheeks 11. The ceiling 10 and the floor 8 of the foldable structure 7 are respectively connected to the longitudinal side wall 3 of the basic cell 2 by a pivot connection axis parallel to the longitudinal axis of the base cell 2. This pivot connection is shown at 13 in the figures for the connection between the ceiling 10 and the longitudinal side wall 3 of the base cell 2 and the reference 14 for the pivot connection between the floor 8 of the foldable structure 7 and the side wall. longitudinal 3 of the basic cell 2.

The longitudinal side face 9 of the foldable structure 7 is coupled to the floor 8 of the foldable structure 7 by a pivot link 15 axis parallel to the longitudinal axis of the base cell 2. The longitudinal side face 9 and the floor 8 of the foldable structure 7 form between them, in the unfolded position and in the folded position of the foldable structure 7, an angle a of a minimum value at least equal to 45 ° and called the value of lower limit angle.

In the folded position of the foldable structure 7, the floor 8 of the foldable structure 7 is folded against the longitudinal side wall 3 of the basic cell 2 and extends substantially parallel to the latter. The longitudinal side face 9 of the foldable structure 7 is, for its part, disposed at least partially covering the ceiling 5 of the base cell. The cheeks 11 of the foldable structure 7 are configured to extend at least partially overlapping the longitudinal side wall 3 of the base cell 2, substantially parallel to said wall 3, in the folded position of the foldable structure 7.

The ceiling 10 of the foldable structure 7 is also folded against the longitudinal side wall 3 of the basic cell 2 and extends substantially parallel to the latter in the folded position of the foldable structure 7. In this position of the foldable structure 7, the ceiling 10 of the foldable structure 7 is interposed between the floor 8 of the foldable structure 7 and the longitudinal side wall 3 of the base cell 2. The cheeks 11 of the foldable structure 7 are, in the example shown, pivotally coupled to the longitudinal side wall 3 of the basic cell 2 by a pivot connection of vertical axis orthogonal to the longitudinal axis of the basic cell 2. These cheeks 11 are here folded against the floor 8 of the foldable structure 7 in the folded position of the foldable structure 7 so that the floor 8 and the ceiling 10 of the foldable structure 7 are arranged between the cheeks and the longitudinal side wall 3 of the basic cell 2.

Alternatively, the cheeks 11 of the foldable structure 7 could have extended between the ceiling 10 of the foldable structure 7 and the longitudinal side wall 3 of the basic cell 2 in the folded position of the foldable structure 7. Similarly, the cheeks 11 of the foldable structure 7 are shown here pivotally coupled to the basic cell 2. They could alternatively be pivotally coupled to the floor 8 or ceiling 10 of the foldable structure 7 to be folded against the floor 8 or the ceiling 10 to which they are coupled without departing from the scope of the invention.

In unfolded position of the base structure 7, the longitudinal lateral face 9 of the foldable structure 7 extends, in the erected state and facing the longitudinal side wall 3 of the base cell 2 and forms, with the cheeks of the foldable structure 7, the side walls of an enclosure 12 adjoining said base cell 2. The ceiling 10 of the foldable structure 7 closes the top of the enclosure 12 in the unfolded position of the foldable structure 7. The floor 8 of the foldable structure 7 extends substantially perpendicularly to the longitudinal side wall 3 of the base cell 2. By substantially perpendicular is meant at 90 ° to plus or minus 15 °. The cheeks 11 extend substantially orthogonally to the longitudinal side wall 3 of the basic cell 2. Again, by substantially orthogonally is meant orthogonally to plus or minus 15 °.

As the longitudinal side face 9 of the foldable structure 7 comes, in the folded position of the foldable structure 7, covering the ceiling 5 of the base cell 2, this longitudinal side face 9 can affect a large number of shapes. Thus, in the example shown, the longitudinal side face 9 of the foldable structure 7 is a curved panel with convexity turned towards the outside of the enclosure 12. This results in a gain in terms of living space at the level of the pregnant 12.

To allow easy deployment or folding of the foldable structure 7, the pivot connection between the longitudinal side face 9 and the floor 8 of the foldable structure 7 is configured to allow said longitudinal side face 9, when the floor 8 is extends substantially at right angles to the longitudinal side wall 3 of the base cell 2 and the longitudinal side face 9 of the foldable structure 7 extends, in the erected state, opposite the longitudinal side wall 3 of the cell 2, to occupy at least two positions, one, said first position, in which it forms with said floor 8 an angle of a value corresponding to the lower limit angle value and extends at least partially inside the area swept by the ceiling 10 of the foldable structure 7 during the displacement of the ceiling 10 of the foldable structure 7 between the folded position against the longitudinal side wall 3 of the basic cell 2 and the closed position of the top of the enclosure 12, the other, said second position, in which, it forms with the floor 8 of the foldable structure 7 an angle of a value called the second highest value at the lower limit angle value, and extends outside the area swept by said ceiling 10 during the displacement of the ceiling 10 between the folded position against the longitudinal side wall 3 of the base cell 2 and the position of closing the top of the enclosure 12.

This pivot connection between the longitudinal side face 9 and the floor 8 of the foldable structure 7 is here formed by a simple hinge. This hinge straddles the outer surface, that is to say facing the outside of the enclosure, the longitudinal side face 9 of the foldable structure 7 and the edge or edge of the floor 8 of the structure 7 foldable.

In the example shown in Figure 16B, the longitudinal side face 9 of the foldable structure 7 occupies the first position in which it rests by its lower edge 17 on the floor surface 8 of the floor stably. The opposite upper edge of the longitudinal side face 9 of the foldable structure 7 is equipped with a reinforcing lining 16.

In the example shown in FIG. 17B, the longitudinal lateral face 9 of the foldable structure 7 occupies the second position in which the angle α, formed between the longitudinal lateral face 9 and the floor 8, is of greater value than the one formed in the first position. In this second position, the longitudinal side wall 9 of the foldable structure 7 is tipped towards the outside of the enclosure and no longer rests in a stable support on the floor 8. This second position allows the ceiling 10 of the foldable structure 7 of unfold without being impeded by the longitudinal side face 9 of the foldable structure 7. Generally, the angular clearance required for the pivot connection of the longitudinal side wall 9 is less than 20 °.

Thus, to allow the deployment of the foldable structure 7, as described above, the deployment method comprises the following steps: a step of pivotally moving the cheeks of the foldable structure 7 to a position in which the cheeks 11 of the foldable structure 7 extend substantially orthogonally to the longitudinal side wall 3 of the base cell 2; a step of driving in pivotal displacement of the movable assembly formed of the floor 8 and of the longitudinal lateral face 9 of the foldable structure 7 in the direction of a lowering of the floor 8 of said mobile assembly from the position in which the longitudinal side face 9 of the foldable structure 7 is disposed at least partially covering the ceiling 5 of the base cell 2 and the floor 8 of the foldable structure 7 is folded against the longitudinal side wall 3 of the base cell to a position in which the floor 8 of the foldable structure 7 extends at right angles to the longitudinal wall 3 of the base cell 2 which it adjoins and the longitudinal side face 9 extends to the erected state, that is to say in a substantially vertical plane and facing the longitudinal side wall 3 of the base cell 2; a step of pivotally moving in the direction of raising the ceiling of the foldable structure to a position in which said ceiling of the foldable structure extends above the longitudinal lateral face 9 of the foldable structure 7; - Then a pivoting step in the direction of a lowering of the ceiling 10 of the foldable structure 7 to a support position of said ceiling 10 on the longitudinal side face 9 of the foldable structure 7.

During the step of pivotally moving in the direction of raising the ceiling 10 of the foldable structure 7, to a position in which it extends above the longitudinal side face 9 of the foldable structure 7 said method comprises: - a synchronous step of pivotal displacement of the longitudinal side face 9 of the foldable structure 7 from the first to the second position; - Then, once the ceiling 10 above the longitudinal side face 9, a step of pivotal displacement of the longitudinal side face 9 of the structure 7 foldable from the second position to the first position before a step of lowering the ceiling 10 of the structure 7 foldable to a bearing position on the longitudinal side face 9 of the foldable structure 7.

These steps are visible in particular in Figures 16A to 18C.

In the example shown, the ceiling 10 of the foldable structure 7 is provided with a fallen edge adapted, in the unfolded position of the foldable structure 7, to partially overlap the outer surface 91, facing outwards. the enclosure 12, the longitudinal side face 9 of the foldable structure 7 at the edge 92 said upper of said longitudinal side face 9. This edge 20 is used to ensure the seal between ceiling 10 and longitudinal side face 9 in unfolded position of the foldable structure 7.

To assist in the displacement drive of the movable assembly formed of the floor 8 and the longitudinal side face 9 of the foldable structure 7, the construction comprises lifting assistance means formed by a winch comprising a drum around which a cable 18 wraps. This cable 18 is able to be hooked, at its free end, to the floor 8 of the moving assembly. The drum of the winch is arranged at the level of the ceiling of the basic cell 2.

To allow folding of the foldable structure 7, it is the reverse of what has been described above. The folding method of the foldable structure 7 thus comprises: a pivoting displacement step in the direction of raising the ceiling of the foldable structure, a driving step in displacement of the longitudinal lateral face 9 since the first to the second position; a step of driving in pivotal displacement in the direction of lowering of the ceiling of the foldable structure to a position folded against the longitudinal side wall of the base cell, a training step in pivotally displacing the longitudinal side face 9 from the second position to the first position; a step of driving in pivotal displacement in the direction of lifting of the moving assembly from the position in which the floor 8 of the foldable structure 7 extends at right angles to the longitudinal lateral wall 3 of the cell; base it adjoins and the longitudinal side face 9 of the foldable structure 7 is in the erect state and facing the longitudinal side wall 3 of the base cell 2 to a position in which the longitudinal side face 9 of the foldable structure 7 is disposed at least partially covering the ceiling 5 of the base cell 2 and the floor 8 of the foldable structure 7 is folded against the longitudinal side wall 3 of the basic cell 2; - And a step of pivotally moving the flanges 11 of the foldable structure 7 in the direction of a flap against the longitudinal side wall 3 of the base cell 2.

It should be noted that the pivotal mounting with clearance between floor 8 and longitudinal side face 9 of the base structure 7 which allows an angular displacement of the longitudinal side face 9 towards the outside of the chamber 12 from its position support by its lower edge on the floor 8 can also be used when folding the foldable structure 7 to facilitate crossing the ceiling of the cell 2 base.

In the example shown, the longitudinal side wall 3 of the base cell 2, opposite to that lined externally by a foldable structure 7, is provided on the one hand with a roll-up awning 21 and on the other hand with two cheeks 22 and a floor 23 foldable against said longitudinal side wall 3 of the base cell 2, the cheeks 22 and the floor 23 in the non-folded position and the awning 21 in the unwound position being able to form a covered terrace adjoining said longitudinal side wall 3 of the base cell 2.

Finally, the base cell 2 is, above its ceiling 5, provided with a solar sensor 31, said solar sensor 31 comprising at least one mirror 32 forming a collector and a receiver 33 of the solar radiation reflected by said at least one mirror 32. The mirror 32 is mounted on a support 35 pivoting about a longitudinal axis of the base cell 2, this support 35 forming a roof element overlapping the ceiling 5 of the base cell 2 in the so-called storage of the mirror and extending transversely to said ceiling 5 in the deployed position of use of the mirror 32.

In folded mode, the curved panel constituting the longitudinal side face 9 of the foldable structure 7 can be placed on the curved panel 35 supporting the mirror, able to concentrate the sun, which was previously folded on the ceiling of the cell. This minimizes the height and bulk of the folded assembly and the mirror during the transport phase.
