optionally actuating the third assembly to move the third assembly in translation longitudinally relative to the frame at least between the open configuration of the shade and the closed configuration, or vice versa, and

- production of electricity by at least some of the panels, and recovery of electricity produced.

The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which:

- Figure 1 is a partial schematic perspective view of a shade according to the invention, the shade being in a closed configuration,

FIG. 2 is a schematic view of the profile of the shelter shown in FIG. 1 along a longitudinal direction of the shelter, FIG. 3 is a schematic view from above of the shade shown in FIGS. 1 and 2, the shade being in an open configuration,

FIG. 4 is a diagrammatic view in section along a longitudinal vertical plane of the shackle shown in FIGS. 1 to 3,

FIG. 5 is a diagrammatic sectional view along a transverse vertical plane of a movable panel of the shackle shown in FIGS. 1 to 3, and

- Figure 6 is a schematic sectional view of a hinge of the frame of the shackle shown in Figures 1 to 3.

Referring to Figures 1 to 4, there is described a shade 1 according to the invention. The shade 1 is adapted to form a shadow 3 on a surface 5 such that a soil advantageously comprises crops or plantations (not shown).

The shade 1 comprises a frame 10 extending in a longitudinal direction L for example substantially parallel to the ground 5, a first set of panels 15 mounted on the frame 10 substantially orthogonal to the same axis of orientation D orthogonal to the longitudinal direction L, a second set of photovoltaic panels, and a third set of photovoltaic panels.

The shade 1 further comprises an actuating system 35 configured to actuate the second set and the third set, at least one open configuration of the shade, shown in Figures 2 to 4, to a closed configuration, shown in Figure 1.

It should be noted that the differences between the first set, the second set and the third set along the direction axis D have been exaggerated in the figures to better distinguish these sets.

The panels 15 of the first set are fixed relative to each other and distributed successively in the longitudinal direction L. In the example shown, the panels 15 are fixed on the frame 10. The panels 15 extend for example in a single P1 plane (Figure 4) substantially perpendicular to the axis of orientation D. Said otherwise, all panels 15 of the first set are at the same level in projection on the axis of orientation D.

According to a variant not shown, the panels 20 of the second set and the panels 30 of the third set are not photovoltaic, but simply opaque. By "opaque" is meant, for example, that the panels are adapted to reduce by at least 80% the radiative flux received on the ground directly from the sun. The panels 20 are fixed to each other, for example using rods 37 (Figure 4), and distributed successively longitudinally. The panels 20 are mounted on the chassis substantially orthogonal to the direction axis D. The second assembly is movable in translation longitudinally with respect to the frame 10 between the open configuration (FIGS. 2 and 3), in which the panels 20 are totally superposed the panels 15 of the first set in view along the axis of orientation D, and the closed configuration (Figure 1), in which the panels 20 completely exceed panels 15 in view along the axis of orientation D.

In the example shown, the panels 15, 20, 30 are structurally identical to each other, so that a total superposition is possible in the open configuration. According to variants not shown, in the open configuration, the superposition of the panels 15 and 20 is not complete.

According to other variants not shown, in the closed configuration, the panels 15 and 20 are not adjacent in view along the axis of orientation D as shown in Figure 1, but are partially superimposed. In all cases, the superposition is less in the open configuration than in the closed configuration, so as to obtain a greater shadow 3 in the closed configuration than in the open configuration.

The panels 20 of the second set extend in a plane P2 substantially parallel to the plane P1, and for example situated below the plane P1 along the axis of orientation D.

The panels 30 of the third set are fixed to each other, for example by longitudinal rods 39, and are successively distributed in the longitudinal direction L. The panels 30 are mounted on the frame 10 substantially orthogonal to the direction axis D. Like the second assembly, the third assembly is movable in translation longitudinally relative to the frame 10 between the open configuration, in which the panels 30 are superimposed with the panels 15 in view along the axis of orientation D, and the closed configuration , in which the panels 30 completely exceed the panels 15.

The panels 30 of the third set extend in a plane P3 parallel to the planes P1 and P2 and situated for example in the plane P2 along the axis of orientation D.

Advantageously, the panels 15, 20, 30 have the same extension E in the longitudinal direction L. Similarly, advantageously, the panels 15, 20, 30 are regularly distributed in the longitudinal direction L and two successive panels 15, 20, 30 respectively of the first set, the second set or the third set are separated longitudinally by the same gap EE.

Alternatively, the rods 37, 39 are replaced by a system of rods (not shown) adapted to move the panels 20, 30 relative to the frame 10.

In the example shown, the gap EE is equal to twice the extension E. Thus, in the closed configuration shown in FIG. 1, the panels 15, 20, 30 are adjacent longitudinally.

The panels 15, 20, 30 have for example a thickness of between 25 mm and

50 mm.

For example, the planes P1, P2, and P3 when the third set is present, are separated by a distance of 100 mm maximum.

The panels 20, 30 advantageously comprise rollers 41 (FIGS.

5).

According to a particular embodiment, the shade 1 does not include the third set of panels. In this case, the gap EE between two successive panels 15 or between two successive panels 20 is advantageously equal to the extension E, and not twice the extension E.

In general, the shade 1 may comprise two, three, four, or more panel assemblies as described above.

According to a particular case (not shown), the panels 15 of the first set are movable in translation relative to the frame 10. They are for example manually operated.

The frame 10 comprises, for example, supports 43 forming posts, and a mobile part 45 movable in rotation relative to the support 43 about a pivot axis Δ substantially parallel to the longitudinal direction L.

The supports 43 are for example regularly spaced longitudinally, and are preferably vertical.

The movable portion 45 is for example movable between a first position, shown in solid lines in Figure 2, wherein the direction axis D is preferably substantially vertical, and a second position, shown in phantom mixed, in which the direction axis D occupies a position D1 forming an angle with the vertical. The angle a is for example between 0 and 60 degrees.

The first position, little or no inclination, is called "summer".

The second position, more inclined, is called "winter" because it is adapted to a sun lower compared to the horizon.

Advantageously, the movable portion 45 is movable by means of a jack 47 between a plurality of positions (two of which are shown).

Alternatively, the movable portion 45 is moved manually, or with the aid of a mechanical system, and locked with a key 49 (FIG. 6) in at least two positions with respect to the supports 43.

The movable portion 45 defines a frame within which the panels 20 and 30 are configured to move. The movable portion 45 comprises for example two side members 51 parallel to the longitudinal direction L, and opposite in a transverse direction T perpendicular to the longitudinal direction L and to the orientation axis D.

The angular position of the axis of orientation D defines the position of the movable portion 45 and the angular orientation of the panels 15, 20 around the pivot axis Δ.

The two longitudinal members 51 support the panels 15, 20, 30 which extend transversely from one spar to the other.

Advantageously, the longitudinal members 51 define grooves 53 adapted to receive the panels 20, 30.

In the example shown, the rollers 41 of the panels 20, 30 are configured to roll in the grooves 53.

According to a variant not shown, the panels 20, 30 are without wheels and slide in the grooves 53.

The actuating system 35 comprises a first rack 55 mechanically connected to the panels 20 of the second set, for example by one of the rods 37, and a second rack 57 mechanically connected to the panels 30 of the third set, for example by one rods 39 (Figures 1 and 4). The actuating system 35 also comprises a gear 59 rotatably mounted on the frame 10 and meshing with the first rack 55 to move it relative to the frame, and on the second rack to move it relative to the frame in opposite opposite directions. by arrows F1 and F2 in FIG. The actuating system 35 also comprises a drive motor 61 (FIGS. 2 and 3) adapted to drive the toothed wheel 59 in rotation.

In the example shown, the actuation system further comprises two other racks 63, 65 mechanically connected respectively to the panels 20 of the second set and the panels 30 of the third set, and another gear 67 meshing on the racks 63, 65 and actuated by the motor 61.

As will be understood, the frame 10 has in the longitudinal direction L a length adapted to the ground 5 to cover. Typically, the length of the frame 10 varies from a few meters to a few tens, or even a few hundred meters.

According to particular embodiments (not shown), the shade 1 may comprise several frames similar to the frame 10, and aligned in the longitudinal direction L and / or the transverse direction T so as to cover a predetermined surface of the ground 5. Thus , the shade 1 may comprise several frames similar to the frame 10 and juxtaposed to each other, each frame comprising panels and drive systems similar to those described above.

The shade 1 also includes electrical circuits, not shown and known in themselves, for collecting the electricity produced by the panels 15, 20, 30.

The operation of the shade 1 will now be described.

In particular according to the season or other criteria, the inclination of the moving part 45 is chosen. To do this, the jack 47 is actuated to put the movable part 45 in the desired position relative to the supports 43, for example the first position or the second position shown in FIG.

In the embodiment where the choice of the inclination is made manually, the key 49 makes it possible to block the mobile part 45 in the chosen position with respect to the supports 43.

To move from the open configuration, shown in Figures 3 and 4, to the closed configuration, shown in Figure 1, the motor 61 rotates the gear wheels 59 and 67. These move the first rack 55 according to the arrow F1, and the second rack 57 according to the arrow F2 (Figure 4). Thus, the panels 20 of the second set are translated longitudinally to the left of Figure 4, while the panels 30 of the third set are translated to the right of Figure 4. It follows that the panels 20 and 30, which were located well below the panels 15 of the first set move respectively to the left and to the right of panels 15 which they were closest to reach the closed configuration shown in Figure 1, wherein the shadow 3 is maximum.

In the example shown, the other racks 63, 65 and the other gear 67 also act to facilitate these displacements.

Thanks to the characteristics described above, the shade 1 is simpler than those of the prior art, and the shadow 3 is adjustable over a wide range of adjustment thanks to the movements of the panels 20, 30, and advantageously the part mobile 35.

Advantageously also, thanks to the toothed wheel 59 meshing with the first rack 55 and the second rack 57, it is possible to obtain a displacement of the second set and the third set with the aid of the single motor 61.

The shade 1 allows a modularity of the shading rate over a very wide range. In the folded and vertical position, it allows rainwater to irrigate crops. The possibility of tilting the movable part 45 makes it possible, in the event of a strong storm, to reduce the wind load. In the deployed position, the movable portion 45 provides crop protection against hail.
