Adjustable shade

The present invention relates to a shade house suitable for forming an adjustable shade on a surface, in particular a planted surface.

The invention also relates to a method for forming and adjusting such a shadow. A shade house is a device for providing shade, usually including a skylight surface and supports. Such a device is described in particular in document JP-A-2016067272. As can be seen in Figure 1 of this document, the shade house has regularly spaced photovoltaic panels. Each panel is mounted tiltable on a post.

Such a shade house requires a large number of posts and panel actuation systems. In addition, it only allows the shadow formed to be adjusted over a relatively limited range of variation.

An object of the invention is to reduce all or part of the above drawbacks, that is to say in particular to provide a simpler shade house while allowing the production of electricity.

To this end, the invention relates to a shade house adapted to form an adjustable shade on a surface, in particular a planted area, the shade house comprising:

- an actuation system configured to actuate the second set, and optionally the third set, at least from the open configuration to the closed configuration, and vice versa.

According to particular embodiments, the shade house includes one or more of the following characteristics, taken alone or in all technically possible combinations:

- The panels have the same extension in the longitudinal direction;

- The panels of the first set are distributed regularly in the longitudinal direction, two successive panels of the first set being separated longitudinally by the same gap; the panels of the second set are distributed regularly in the longitudinal direction, two successive panels of the second set being separated longitudinally by said gap; and optionally the panels of the third set are distributed regularly in the longitudinal direction, two successive panels of the third set being separated longitudinally by said gap, said gap being substantially equal to twice said extension if the shade house includes the third optional set, or substantially equal to said extension if the shade house does not include the third optional set;

- The chassis comprises two opposite side members in a transverse direction perpendicular to the longitudinal direction; and the panels of the second set and optionally the panels of the third set extend transversely between the side members and are supported by the side members;

- the chassis comprises at least one support, and a movable part including the two longitudinal members, the movable part being displaceable in rotation relative to the support around a pivot axis substantially parallel to the longitudinal direction between at least two distinct positions.

The subject of the invention is also a method for forming and adjusting a shadow on a surface, comprising the following steps:

- supply of a shade house as described above,

- actuation of the second set to move the second set in translation longitudinally with respect to the chassis at least between the open configuration of the sunshade and the closed configuration, or vice versa,

- optionally actuation of the third assembly to move the third assembly in translation longitudinally with respect to the chassis at least between the open configuration of the canopy and the closed configuration, or vice versa, and

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

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

FIG. 1 is a partial schematic perspective view of a shade house according to the invention, the shade house being in a closed configuration,

FIG. 2 is a schematic profile view of the shade house shown in FIG. 1 in a longitudinal direction of the shade house,

FIG. 3 is a schematic top view of the shade house shown in FIGS. 1 and 2, the shade house being in an open configuration,

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

FIG. 5 is a diagrammatic view in section along a transverse vertical plane of a movable panel from the shade house shown in Figures 1 to 3, and

- Figure 6 is a schematic sectional view of an articulation of the sunshade chassis shown in Figures 1 to 3.

With reference to FIGS. 1 to 4, a shade box 1 according to the invention is described. The shade house 1 is adapted to form a shadow 3 on a surface 5 such as a soil advantageously comprising crops or plantations (not shown).

The shade house 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 orientation axis D orthogonal to the longitudinal direction L, a second set of photovoltaic panels 20, and a third set of photovoltaic panels 30.

The shade 1 further comprises an actuation system 35 configured to actuate the second set and the third set, at least from an open configuration of the shade, shown in FIGS. 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 successively distributed in the longitudinal direction L. In the example shown, the panels 15 are fixed to the frame 10. The panels 15 extend for example in the same plane P1 (Figure 4) substantially perpendicular to the orientation axis D. In other words, all the panels 15 of the first set are located at the same level in projection on the orientation axis 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. For example, "opaque" means that the panels are suitable for reducing the radiation flux received on the ground directly from the sun by at least 80%.

The panels 20 are fixed to each other, for example using rods 37 (Figure 4), and successively distributed longitudinally. The panels 20 are mounted on the chassis substantially orthogonal to the direction axis D. The second assembly is movable in translation longitudinally relative to the chassis 10 between the open configuration (Figures 2 and 3), in which the panels 20 are completely superimposed to the panels 15 of the first set in view along the orientation axis D, and the closed configuration (FIG. 1), in which the panels 20 completely protrude from the panels 15 in view along the orientation axis D.

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

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 overlap is less in the open configuration than in the closed configuration, so as to obtain a greater shade 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 located 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 distributed successively in the longitudinal direction L. The panels 30 are mounted on the frame 10 substantially orthogonally to the direction axis D. Like the second set, the third set is movable in translation longitudinally with respect to the chassis 10 between the open configuration, in which the panels 30 are superimposed with the panels 15 in view along the orientation axis D, and the closed configuration , in which the panels 30 completely protrude from the panels 15.

The panels 30 of the third set extend in a plane P3 parallel to the planes P1 and P2 and located for example under 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 distributed regularly 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 distance EE.

According to a variant, the rods 37, 39 are replaced by a system of rods (not shown) adapted to move the panels 20, 30 relative to the chassis

10.

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

The panels 15, 20, 30 for example have 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 at most.

The panels 20, 30 advantageously include rollers 41 (Figures 4 and 5).

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

Generally, the shade 1 may include two, three, four, or more, sets of panels as described above.

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

The chassis 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 advantageously vertical.

The movable part 45 can for example be moved between a first position, shown in solid lines in FIG. 2, in which the direction axis D is advantageously substantially vertical, and a second position, shown in dashed lines, in which the axis of direction D occupies a position D1 forming an angle a with the vertical. The angle a is for example between 0 and 60 degrees.

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

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

Advantageously, the movable part 45 can be moved using a jack 47 between a plurality of positions (two of which are shown).

As a variant, the mobile part 45 is moved manually, or using a mechanical system, and locked using a key 49 (FIG. 6) in at least two positions relative to the supports 43.

The movable part 45 defines a frame inside which the panels 20 and 30 are configured to move. The movable part 45 comprises for example two longitudinal 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 orientation axis D defines the position of the mobile part 45 and the angular orientation of the panels 15, 20 around the pivot axis Δ.

The two beams 51 support the panels 15, 20, 30 which extend transversely from one beam 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 devoid of rollers and slide in the grooves 53.

The actuation 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 actuation system 35 also comprises a toothed wheel 59 rotatably mounted on the chassis 10 and meshing on the first rack 55 to move it relative to the chassis, and on the second rack to move it relative to the chassis in opposite opposite directions by arrows F1 and F2 in Figure 4.

The actuation system 35 also includes a drive motor 61 (Figures 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 to the panels 30 of the third set, and another toothed wheel 67 meshing on the racks 63, 65 and powered by the motor 61.

As will be understood, the chassis 10 has in the longitudinal direction L a length suitable for the ground 5 to be covered. Typically, the length of the chassis 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 can 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 include several chassis similar to chassis 10 and juxtaposed to each other, each chassis comprising sets of 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.

Depending on the season or other criteria, the inclination of the movable 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. 2.

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

To pass from the open configuration, represented in FIGS. 3 and 4, to the closed configuration, represented in FIG. 1, the motor 61 rotates the toothed wheels 59 and 67. These move the first rack 55 according to the arrow F1, and the second rack 57 according to 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. As a result, the panels 20 and 30, which were located perfectly below the panels 15 of the first set move respectively to the left and to the right of the panels 15 to which they were closest to reach the closed configuration shown in Figure 1, in which the shadow 3 is maximum.

In the example shown, the other racks 63, 65 and the other toothed wheel 67 act in the same way to facilitate these movements.

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

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

Shade 1 allows 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 resistance. In the deployed position, the mobile part 45 provides crop protection against hail.
