Description

Title of the invention: Module for assembling a shade house

[0001] The invention relates to a module for assembling a shade for photovoltaic panels, for example for assembling a parking surface shade. The invention also relates to a rafter and a post for such a module.

[0002] In France, since 2022, it has been mandatory to cover at least half of the surface area of ​​a parking space (or "parking lot"), particularly one over 1500 m2, with photovoltaic canopies. These self-consumption canopies are an ecological as well as economical solution for manufacturers who own such parking spaces. Since then, the demand for these canopies has increased. The deployment of canopies is a fairly time-consuming iterative process that generally requires several studies, particularly of the ground, wind, snow, and several validation stages before being able to define a suitable framework. Then, this framework includes accessories that are supplied by different parties. However, this method is quite time-consuming, on the one hand for the time spent in the iterative process, on the other hand due to a constant need to coordinate the parties.

[0003] Already known from the prior art, in particular from document EP3850749, is a system for installing a shade structure forming a kit which comprises several identical support elements intended to be fixed in the ground according to different desired configurations. Each support element comprises a main support, comparable to a post, having a curved region and a support part for supporting photovoltaic panels. Two support elements can be positioned adjacently, thus having a general “Y” (or “butterfly”) type shape, or else being spaced apart with their free ends joining, having an “inverted U” (or “saddle”) type shape. However, such support elements are particularly bulky due to their shape. Furthermore, they allow the shade structures to be mounted in only two configurations, and do not, for example, allow the shade structures to be mounted in a “T” configuration.Therefore, if you want to obtain such a shade configuration, it is necessary to provide another kit, with specific or even custom-made support elements, which can increase manufacturing times.

[0004] The present invention aims in particular to provide a module for the assembly of a shade offering a wide variety of possible configurations, making it possible to facilitate stock management and reduce the manufacturing time of a shade, in particular thanks to standardization of the parts.

[0005] To this end, the invention relates to a module for assembling a shade for photovoltaic panels, the module comprising a post and a rafter configured to be fixed to the post in an inclined manner relative to a horizontal plane perpendicular to the post, characterized in that the rafter is capable of taking two distinct fixing positions on the post, namely a rising position and a descending position, the rising position being distinguished from the descending position by the reversal of the rafter around the horizontal plane or around a vertical plane.

[0006] The term "rafter" preferably means a piece of framework, for example made of wood or metal, attached to a vertical post and supporting purlins, particularly adapted to support photovoltaic panels.

[0007] The claimed invention proposes to decompose the post and the rafter into two separate parts in order to increase the modularity of the assembly module and also to improve the compactness of this module for its transport.

[0008] Thanks to the proposed invention, the same rafter is capable of taking two distinct positions of choice for its attachment to the post, in particular so that the shade can be assembled according to different configurations of choice. Indeed, by turning the same rafter along a horizontal plane relative to the post, this rafter can pass from a so-called rising position relative to the post to a descending position, or vice versa. A distinct position chosen makes it possible to form a shade of a particular configuration. It is noted that the modularity of the assembly is improved but also that the manufacturing costs are reduced given that all the rafters and / or posts can be mass-produced, in a standardized manner, without worrying about the specifications linked to particular configurations.Thus, whereas until now, to manufacture a shade on a parking area, studies were first carried out concerning the ground, the wind, the snow cover of the area, then the design of the frame and its manufacture were launched, the module proposed here offers a plurality of configurations so that the design and supply phase of the parts can be greatly reduced. In other words, the module proposed here makes it possible to facilitate stock management, accelerate manufacturing and produce shades in mass.

[0009] In addition or alternatively, the change of position of the rafter relative to the post is possible by turning the rafter relative to the post around a vertical plane. In other words, the same rafter can be fixed by a first end to the post, imposing a certain orientation of the rafter relative to the post, and by turning the rafter around the vertical plane, it can be envisaged that it is fixed to the post by its opposite end, imposing another orientation of the rafter relative to the post. Thus, the invention provides a assembly in which the rafter does not have a single fixing position on the post. As a result, by combining several modules such as the one proposed here, the possible configurations on the parking surface are increased even more.

[0010] It is understood that in the particular case where the rafter can take distinct positions both by turning the rafter around the horizontal plane and around a vertical plane, then it is possible to propose a rafter which can take four distinct positions relative to the post.

[0011] The module may further comprise one or more of the following optional features, taken alone or in combination.

[0012] - The rafter comprises an elongated body having a longitudinal axis and two ends, at least one of the ends having an inclined surface, i.e. extending along a plane not perpendicular to the longitudinal axis of the rafter. Thus it is understood that the “inclined surface” has an angle other than 90° relative to at least one adjacent wall of the rafter. The angle may be acute, i.e. less than 90°, or obtuse, i.e. greater than 90°.

[0013] By providing an inclined surface at one end, the same rafter is capable of being fixed to the post in a rising position or a falling position by turning around the horizontal plane, without having to undergo geometric modifications, for example by machining. Indeed, when the end of the rafter is pressed against the post for its fixing, depending on its inclination, the inclined surface simultaneously allows the rafter to be inclined relative to the horizontal plane so that it can adopt the rising position or the falling position.

[0014] - Each end of the rafter has an inclined surface. By providing an inclined surface at each end, the same rafter is capable of being fixed to the post in an upward or downward position by turning around the vertical plane without having to undergo geometric modifications.

[0015] According to one embodiment in this case, the inclined surfaces of each end are intersecting with respect to each other, that is to say not parallel. Thus, it is possible to envisage a reversal with respect to a horizontal plane and a reversal with respect to a vertical plane so as to obtain distinct inclinations in the four positions.

[0016] According to another embodiment, the inclined surfaces of each end are parallel.

[0017] - The inclined surface of the rafter is inclined at an angle between 2 and 15°, preferably between 3 and 10°, more preferably close to 5° (degrees) relative to a plane perpendicular to the longitudinal axis of the rafter. The 5° inclination is particularly interesting for obtaining T or Y configurations.

[0018] - The post comprises means for receiving fixing elements of the rafter, these receiving means being configured so that the rafter can be fixed at two distinct heights on the post, one of the heights corresponding to the upward position of the rafter and the other of the heights corresponding to the downward position.

[0019] The term "height of attachment of the rafter to the post" means the distance which separates, on the post, the lower end of the rafter from the ground in which the post is fixed, or from the lower end of the post if the post is not buried. It is therefore understood that the greater this distance, the higher the rafter is in the position on the post.

[0020] - The height of the rafter on the post, when it is fixed in the upward position, is greater than the height of the rafter on the post when fixed in the downward position.

[0021] - The rafter and the post each include fixing holes for allow the rafter to be fixed to the post, the post comprising a number of fixing holes strictly greater than those of the rafter, for example the post comprises six fixing holes distributed in three rows of two holes, the rows being offset in height, and the rafter comprises four fixing holes distributed in two rows of two holes, the rows being offset in height. By providing a strictly greater number of fixing holes on the post, it is possible to selectively align the fixing holes of the rafter with those of the post to allow the shade to be mounted in different configurations and according to the desired height.

[0022] Thus, with the proposed module, it is possible to form a shade having a so-called "simple high" configuration or a so-called "simple low" configuration corresponding respectively to a mounting of the rafter according to the rising position or according to the descending position. Preferably, in the "simple high" configuration the rafter is fixed in the rising position at a height greater than that of the "simple low" configuration in which the rafter is fixed in the descending position.

[0023] - The module includes, in addition to the post and the rafter, a brace and a plate of sealing. A brace is preferably understood to mean an inclined piece of wood or metal, connecting an area near the free end of the rafter to the post to support the rafter. The brace contributes to the bracing of the module once assembled.

[0024] The brace therefore makes it possible to mechanically support the rafter when the latter is fixed to the post according to the chosen position. In particular, the brace makes it possible to support the configuration adopted by the module. Generally, the brace has one end fixed to the post and another opposite end, supporting the rafter.

[0025] According to one embodiment, the end fixed to the post and the end fixed to the rafter are each fixed by pivot connection. Thanks to these pivot connections, the fixing of the brace can easily adapt to the chosen position (rising or descending) for the rafter on the post. Indeed, one or the other end of the brace can be fixed on the rafter or the post, without worrying about the order of fixing. The brace is therefore more easily handled and the assembly of the module is facilitated.

[0026] According to another embodiment, only the end fixed to the post, or only the end fixed to the rafter, is fixed by pivot connection. Thanks to this pivot connection, the brace is articulated on the post or on the rafter so that the same brace is capable of supporting the rafter whatever the chosen fixing position (rising or descending).

[0027] Thus, whether there is one or two pivot connections on the brace, it is not required to provide braces of different shapes or sizes depending on the chosen fixing position of the rafter. Consequently, the number of parts required for the assembly of the module is reduced. In addition, for an assembly of several modules, the braces can be manufactured in a standardized manner, which further reduces manufacturing costs.

[0028] - The module further comprises another rafter and another brace, the other rafter that can also take two separate fixing positions on the post, namely a rising position and a falling position. Thanks to the additional rafter, the shade is able to adopt two new additional configurations. Indeed, in addition to the “single high” and “single low” configurations, it is possible to form a shade with a “T” configuration or a “Y” configuration when two rafters are mounted on either side of the same post.

[0029] In particular, in the “T” configuration, one of the rafters is fixed on a first side of the post in the upward position and the other rafter is fixed on a second side opposite the first side, in the downward position, thus forming the upper base of the “T”, which is slightly inclined relative to the horizontal plane perpendicular to the post.

[0030] Advantageously, in the "T" configuration, the rafters are offset in height relative to each other. The rafter fixed in the upward position is arranged at a height greater than that of the rafter arranged in the downward position.

[0031] In the "Y" configuration, the two rafters are fixed in the upward position on either side of the post. Advantageously, the two rafters are arranged at the same height.

[0032] The two configurations "Y" and "T" make it possible to have a shade comprising photovoltaic panels on either side of the post so as to obtain two separate shaded spaces with the fewest possible parts, i.e. with a module comprising a post and two rafters.

[0033] - The rafter is a piece of metal or wood.

[0034] - The rafter is of the “IPN” type (or “Normal profile I-beam”) presenting a constant “I” section.

[0035] - The rafter is equipped with purlin fixing holes to support panels photovoltaic panels, these fixing holes being arranged on two opposite surfaces of the rafter. Thus, whatever the fixing position of the rafter after a reversal (upward or downward), the fixing holes are easily accessible to allow the mounting of the photovoltaic panels. It is therefore understood that the rafter does not have to undergo additional modifications or does not require additional parts, other than the purlins, for the mounting of photovoltaic panels after its reversal.

[0036] - The post is intended to be fixed to the ground, vertically. The module comprises preferably a pre-sealing plate, added or placed on the lower end of the post.

[0037] The invention also relates to a rafter for a module as described above, configured to take two distinct fixing positions on a post, namely a rising position and a descending position.

[0038] The invention also relates to a post for a module as described above, configured to receive a rafter in two distinct fixing positions, namely a rising position and a descending position. Brief description of the figures

[0052] Figures 1 to 5b show a module 1 for assembling a shade for photovoltaic panels.

[0053] In all that follows, the orientations are the orientations of the figures. In particular, the terms "upper", "lower", "left", "right", "above", "below", "towards the front" and "towards the back", "on the side" are generally understood in relation to the direction of representation of the figures.

[0054] The invention relates to a module 1 for assembling a shade for photovoltaic panels, in particular adapted for mounting on a concrete foundation. In addition, the module 1 is adapted to be mounted in parking spaces, but the invention is not limited to such a location. Furthermore, the module 1 is adapted to be mounted in geographical areas at altitude, for example 400m, in particular in alpine environments. The module 1 can also be mounted in geographical areas at relatively low altitude, for example 200m. Preferably, for a module 1 mounted in an alpine environment, called an “ALPINE shade”, the module 1 is capable of undergoing significant loads, for example of the order of 240 daN / m2 (decaNewton per square meter).Alternatively, for a module 1 mounted in a relatively low altitude environment, called a "PLAIN shade", the module 1 is capable of undergoing lower loads, for example of the order of 215 daN / m2. By "loads" we mean any meteorological force that the module 1 can undergo in its environment, for example wind force, snow weight, rain force among others.

[0055] [Fig.l] represents module 1 which comprises at least two separate parts: a post 2 and a rafter 3.

[0056] The post 2 extends along a longitudinal axis X making it possible to define a vertical direction X when the post is fixed in the ground, a horizontal plane H which is perpendicular to the vertical direction X, and a vertical plane V passing through the axis X.

[0057] The rafter 3 is configured to be fixed to the post 2 in an inclined manner relative to the horizontal plane H. The post 2 has a lower end 21 adapted to be fixed to the ground, in particular in a concrete foundation for the assembly of the module 1 and an upper end 22 at which the rafter 3 is fixed. In particular, in [Fig.l], the rafter 3 is supported by a brace 4.

[0058] As shown in Figures 2a and 2b, the same rafter 3 is capable of taking two distinct fixing positions on the post 2, namely a rising position ([Fig. 2a]) and a descending position ([Fig. 2b]). It is possible to move from the rising position to the descending position, and vice versa, by turning the rafter 3 relative to the horizontal plane H or relative to the vertical plane V. Thus, as visible in these figures, the same rafter 3 is capable of taking a fixing position of choice according to the user's preferences. A distinct position chosen makes it possible to form a shade of a particular configuration.

[0059] In [Fig. 2a], the rafter 3 is fixed to the post 2 in the upward position. Such a fixing makes it possible to form a shade having a so-called “simple high” configuration. This same rafter 3, after its reversal relative to the horizontal plane H, can be fixed to the post 2 in the downward position, as shown in [Fig. 2b]. This has the effect of increasing the modularity of the assembly but also of reducing manufacturing costs since all the rafters 3 can be mass-produced, in a standardized manner, without worrying about specifications linked to particular configurations.

[0060] According to the invention, such a change of position is possible, alternatively or in combination, by turning the rafter 3 relative to the vertical plane V. In fact, the rafter has walls at its ends which allow it to have different fixing positions by turning around the horizontal plane H or the vertical plane V.

[0061] In each “simple high” or “simple low” configuration, the rafter 3 is supported by the brace 4, the latter extending in an inclined manner with one end 41 fixed to the post 2 and another end 42 fixed to the rafter 3 so as to contribute to the bracing of the module 1, to ensure the overall stability of the assembly.

[0062] Advantageously, the end 41 is fixed to the post 2 by a pivot connection. Thanks to this pivot connection, the brace 4 is articulated on the post 2 so that the same brace 4 is capable of supporting the rafter regardless of its fixing position (rising or descending). [Fig. 2c] represents a fixing means, for example here a clevis head 43 which can be fixed on the post 2 to receive the end 41. Alternatively, the clevis head 43 can be fixed on the end 41 of the brace 4. The clevis head 43 comprises a “U”-shaped body whose opposite branches 44, 44' are each provided with an eyelet 46, 46', said eyelets being arranged opposite one another along a pivot axis P. The end 41 of the brace 4 is adapted to be received between the branches 44, 44' in a pivotable manner around the pivot axis P. Preferably, the other end 42 of the brace 4, intended to support the rafter 3, is also configured to be fixed on the rafter 3 by a pivot connection. This pivot connection is made possible by means of a clevis head 43 similar to that described for the articulation of the brace 4 on the post 2.

[0063] Advantageously, the module 1 further comprises another rafter 3' and another brace 4', in particular to allow the module 1 to be mounted in two additional configurations called "T" configuration and "Y" configuration. Such configurations are shown in Figures 3a and 3b respectively.

[0064] In particular, in [Fig. 3a], the module has a “T” configuration with one of the rafters 3' fixed in a rising position on one side (left side) of the post 2, and the other rafter 3 fixed in a falling position on the opposite side (right side) of the post 2. Each of the rafters 3, 3' is supported respectively by a brace 4, 4'. Advantageously, the rafters 3, 3' are offset in height so as to be aligned with each other so that the upper base of the “T” formed by the rafters 3, 3' is linear.

[0065] In [Fig. 3b], the module has a “Y” configuration with the two rafters 3, 3' fixed in a rising position on either side of the post 2. Once again, the rafters 3, 3' are respectively supported by the braces 4, 4'. For the “Y” configuration, the rafters 3, 3' are advantageously arranged at the same height.

[0066] [Fig. 4a] represents a longitudinal sectional view of the rafter 3 isolated from the module 1. Advantageously, the other rafter 3' comprises the same structure as the rafter 3.

[0067] The rafter 3 comprises an elongated body 30 having a longitudinal axis A and two ends 31, 32. In [Fig. 4a], the end 32 has an inclined surface extending along a plane not perpendicular to the longitudinal axis A of the rafter 3. The end 31, in this example, is on the other hand perpendicular to the longitudinal axis A of the rafter 3, however it is also possible to imagine a rafter 3 of which each of the two ends 31, 32 has an inclined surface, as notably shown in [Fig. 4c].

[0068] The inclined surface of the end 32 allows the same rafter 3 to be fixed on the post 2 according to the rising position or the falling position. Indeed, when the end 32 of the rafter 3 is pressed against the post 2 for its fixing, the inclination of the inclined surface 32 allows at the same time the rafter to tilt with respect to the horizontal plane H. Thus, according to the inclination of this inclined surface 32, the rafter 3 is capable of adopting the rising position or the falling position, according to an angle corresponding to the angle of the inclined surface 32 with respect to a direction perpendicular to the longitudinal axis A. Optionally, the surfaces of each end 31, 32 are parallel to each other.

[0069] The inclined surface 32 is inclined at an angle of between 2 and 15°, preferably between 3 and 10°, more preferably close to 5° (degrees) relative to a plane perpendicular to the longitudinal axis A of the rafter 3.

[0070] Furthermore, the elongated body 30 is equipped with holes 33 for fixing purlins to support photovoltaic panels. As visible in [Fig. 4a], and in an original manner for a rafter, holes 33 for fixing the purlins are arranged on two opposite surfaces of the elongated body 30, so that the holes 33 are accessible from the top for supporting the photovoltaic panels, regardless of the reversal carried out on the rafter.

[0071] Preferably, the rafter is of the “IPN” or “Normal Profile I-Beam” type having a constant “I” section. Advantageously, the fixing holes 33 are formed in the upper and lower surfaces of the “I”. [Fig. 4b] shows a top view of the rafter 3 of [Fig. 4a]. As can be seen, the receiving elements 33 are in the form of fixing holes. Advantageously, two fixing holes are provided to receive a purlin.

[0072] For its fixing, the rafter 3 comprises fixing elements 350. These elements 350 are preferably in the form of fixing orifices 35 formed in the inclined surface of the end 32 of the rafter 3. This surface 32 provided with fixing orifices 35 is visible in [Fig. 4d]. In this figure, the rafter 3 comprises four fixing orifices 35 with two rows of orifices, offset in height. In addition, here the inclined surface 32 comprises positioning orifices 36 to facilitate the mounting of the rafter 3.

[0073] Advantageously, the post 2 comprises means 250 for receiving the fixing elements 350 of the rafter 3. In [Fig. 4e], the post 2 comprises receiving means 250 which comprise six fixing orifices 25 distributed in three rows of two orifices 25, offset in height. Of course, it is possible to provide receiving means 250 and fixing elements 350 of different shapes. It is also possible to provide receiving means 250 and fixing elements 350 of different numbers. However, the number of receiving means 250 is advantageously strictly greater than the number of fixing elements 350. Thus, the post 2 comprises a number of fixing holes 25 strictly greater than those of the rafter 3. By providing a number of fixing holes 25 strictly greater on the post 2, it is possible to selectively align the fixing holes 35 of the rafter 3 with those of the post 2 to allow the shade to be mounted according to different configurations and according to a desired height.

[0074] In particular, these receiving means 250 are configured so that the rafter 3, 3' can be fixed at two distinct heights on the post 2, one of the heights corresponding to the rising position of the rafter 3 and the other height corresponding to the descending position.

[0075] Figures 5a, 5b are an enlargement of the fixing of the rafters 3, 3' on the post 2 respectively according to the “T” configuration and the “Y” configuration.

[0076] In particular, in Figure 5a, the rafters 3, 3' are offset in height relative to each other. The rafter 3 (on the right) fixed in the descending position is positioned at a lower height relative to the rafter 3' (on the left) fixed in the ascending position. The fixing holes 35 of the rafter 3 on the right are engaged with the fixing holes 25 of the post 2, in particular by a screwing system. Preferably, a sealing plate 5 is provided for fixing the rafter 3.

[0077] More precisely, the right rafter 3 comprises two fixing holes 35 offset in height and the post 2 comprises three fixing holes 25 offset in height, namely an upper fixing hole, an intermediate fixing hole and a lower fixing hole. The two fixing holes 35 of the rafter 3 are aligned respectively with the two intermediate and lower fixing holes 25 of the post 2 for their engagement. The upper fixing hole 25 of the post 2 remains free of any engagement.

[0078] Similarly, the left rafter 3' comprises two fixing holes 35, but which are aligned with the intermediate and upper fixing holes 25 of the post 2 for their engagement. Here, the lower fixing hole 25 remains free of any engagement. Thus, thanks to a number of fixing holes 25 on the post 2 strictly greater than the number of fixing holes 35 on the rafters 3, 3', it is possible to fix these rafters 3, 3' at different heights. The term "height of fixing of the rafter on the post" means the distance D, D' which separates, on the post 2, the lower end of the rafter 3, 3' from the ground in which the post is fixed, or from the lower end of the post if the post is not buried. It is understood that the greater this distance, the higher the rafter is in the position on the post. In the example the height D' is greater than the height D.

[0079] In Figure 5b, the rafters 3, 3' are both fixed in a rising position and are positioned at the same height on the post 2. Preferably, the fixing holes 35 of the rafters 3, 3' are aligned with the intermediate and upper fixing holes 25 of the post 2, leaving the lower fixing hole free. Alternatively, it is also possible to align the fixing holes 35 of the rafters 3, 3' with the intermediate and lower fixing holes 25, while maintaining the same height between the rafters 3, 3'.

[0080] The invention is not limited to the examples described. It is possible in particular not to provide a height offset between two rafters 3, 3' regardless of the configuration of the shade chosen. List of references
