    FRAME FOR MOUNTING SOLAR PANELS
    The present invention relates to a pre-assembled mounting frame (or chassis) for installing solar panels, in particular to roofs or walls.
    Solar panels or photovoltaic panels must be mounted optimally in the direction of the sun. Furthermore, the panels must be mounted firmly and stably. Mounting said panels is a time-consuming job, not least because it must be ensured that the panels are positioned correctly.
    Various types of frames for solar panels are known in the art.
    DE2020060019837 (EP1783440) describes a triangular chassis comprising three connected legs, one standing leg being telescopic. This is also the case in WO2010 / 014754 and, moreover, the use of an actuator to adjust the angle is described there.
    DE9003220 describes a construction in which an intermediate leg is mounted somewhere in the middle of the other two legs.
    WO002073703 describes a foldable chassis comprising three legs, one leg at the bottom and two legs foldable in a 90 ° position.
    DE202009007516 describes a foldable chassis comprising three separate legs and a specific hinge for mounting said legs in a triangular frame. However, the hinge has a rather complicated structure.
    FR2890725 describes a pre-assembled foldable chassis for solar panels, comprising three sections with two permanent hinges and one opening hinge, to be mounted in a single triangular fixed position chassis.
    The aforementioned known systems for mounting solar panels all have the disadvantage that either only one fixed position can be taken or that a telescopic leg must be used, which is a weak and extra complicated component in the construction. This one fixed position results in only one fixed angular position of the solar panel. There are no means for adjusting the position to the angle of the type of surface or in the direction of the sun.
    FR2494408 describes an angle adjustment by clamping one leg on the other with a bolt with two screw ends. A variant uses a motor for the angle adjustment. These are on the one hand clumsy and on the other more complex designs.
    DE29610516 describes a device for mounting solar panels consisting of a bottom plate with upright wall and a folding leg left and right thereof that is held up by a third leg, wherein the folding leg can be adjusted in the corner by the position of the third leg in different holes. However, the whole is not compact due to the bottom plate.
    It is therefore an object of the present invention to provide a simple and strong frame that is nevertheless adaptable to different angular positions for optimally mounting the solar panel in the direction of the sun and taking into account the mounting surface.
    To this end, the present invention provides a pre-assembled foldable frame for mounting a solar panel on a surface or base frame, comprising three legs, one end of a second and one end of a third leg foldable on the first and second end of a first leg are mounted, said second and third leg being lockable relative to each other, characterized in that the end of said third leg is lockable relative to said second leg over at least a portion of the length of said second leg, that the angle between said second and first leg is adjustable.
    The term "adaptable" means that the structure ensures that the angle between the first and second leg is adjustable in different angles, by adjusting the position of the connection between the second and third leg.
    In one embodiment, the third leg is lockable with respect to said second leg by means of an adjustable connection.
    In another embodiment, the end of said third leg is fixed relative to said second leg by means of a slidable construction along said second leg. In a preferred embodiment, the end of said third leg is permanently arranged or connected within the guide means of said slidable structure.
    The end of said third leg is lockable with respect to said second leg at discrete or continuous positions.
    In one embodiment, the third leg is lockable with respect to said second leg in discrete positions or holes spread over at least a portion of the length of said second leg. In another embodiment, the third leg is lockable in continuous positions (or in any position) with respect to said second leg by a means exerting friction between the end of said third leg and said second leg. Other means for positioning at any angle may also apply.
    In one embodiment, the first leg is a base leg that is mountable on said surface or base frame. In another embodiment, the second leg is a base leg that is mountable on said surface or base frame.
    In one embodiment, the third leg can be telescopic. In another embodiment, it is provided that said third leg has different lengths for providing different angle ranges. In a preferred embodiment the angle between said second and first leg is adjustable in steps of 10 °, preferably 5 °. Preferably the angle between said second and first leg is 15 °, 20 °, 25 ° or 30 °.
    In one embodiment, the second and third legs are foldably mounted on said first leg by means of permanent shafts. The second and third legs are preferably fixable by means of a shaft, nut and bolt or pop rivet.
    In a specific embodiment, the base leg includes supports over at least a portion of the length of said base leg for fixing to said surface or base frame.
    In a second aspect, the present invention provides a method for mounting a solar panel on a surface or base frame by means of a pre-assembled foldable frame as described above, comprising the steps of: a) mounting the first leg on the surface or base frame, b) unfolding the second and third leg, and c) securing the second and third leg relative to each other in a position wherein the angle of the first and second leg is adjusted to the orientation of the sun; wherein steps a) and b) can be exchanged.
    In an alternative embodiment, the present invention provides a method for mounting a solar panel on a surface or base frame by means of a pre-assembled foldable frame as described above, comprising the steps of: a) mounting the second leg on the surface or base frame, b) unfolding the first and third legs, and c) securing the second and third legs relative to each other in a position wherein the angle of the first and second legs is adjusted to the orientation of the sun; wherein steps a) and b) can be exchanged.
    In a third aspect, the present invention provides for the use of a frame as specified herein for mounting solar panels on a horizontal, vertical or sloping structure.
    The frame of the present invention is particularly advantageous for mounting a solar panel on a flat or slightly sloping surface, such as a roof or wall. The slope angle can be adjusted to the slope of the roof and the optimum positioning in the direction of the sun.
    Specific embodiments of the present invention will now be described by way of example, with reference to the accompanying figures:
    Figure 1 is a representation of a pre-assembled mounting frame of the invention in (a) unfolded and (b) folded position.
    Figure 2 is a representation of a basic profile of a pre-assembled mounting frame according to an embodiment of the invention for applying the frame to a surface.
    Figure 3 is a representation of a mounting profile of a pre-assembled mounting frame according to an embodiment of the invention, on which a solar panel can be mounted.
    Figure 4 is a representation of an intermediate profile of a pre-assembled mounting frame according to three specific embodiments (a: 15 °, b: 20 °, c: 30 °) of the invention.
    Figure 5 is a representation of a pre-assembled mounting frame according to a specific embodiment of the invention.
    Figure 6 is a representation of a pre-assembled mounting frame according to a specific embodiment of the invention at an angular position of 25 °.
    Figure 7 is a representation of a pre-assembled mounting frame according to another embodiment of the invention, the adaptable structure being applied to the base profile.
    Figure 1a shows a pre-assembled mounting frame according to a first aspect of the invention. The frame comprises a base profile (1) for mounting the frame on a surface, a mounting profile (2) for mounting a solar panel and an intermediate profile (3) for controlling the angle between the base profile and the mounting profile.
    The mounting profile (or "second" leg) (2) and the intermediate profile (or "third" leg) (3) are pre-assembled on the base profile (or "first" leg) by a fastener, e.g. a bolt and nut, arranged through openings (4) at the ends of the profiles. Between the two nuts, the bolt can be inserted into a tubular element that provides additional strength and prevents the bolt and nut system from being tightened above the deformation of the profile. Other fasteners are pop nails.
    The other ends (5) of the mounting profile (2) and the intermediate profile (3) can be connected to each other via an adjustable construction.
    The profiles (1, 2, 3) are dimensioned in such a way that the intermediate profile (3) can be folded onto the base profile (1) and the mounting profile (2) can be folded onto the intermediate profile (3) for easy and compact handling and transportation. In the folded position, the pre-assembled frame assumes the dimensions of the base profile (1) with an additional thickness of the other two profiles (2, 3) folded up at the top, as shown in Figure 1b.
    In a preferred embodiment, the profiles (1, 2, 3) are U-shaped. The dimensions of the U-profiles are such that they can be stacked on top of each other for a compact folding via the foldable constructions for connection to each other. To this end, the connections are such that a completely compact fold is achieved. This can be achieved by correct alignment of the openings for arranging the fixing means.
    The U-profiles preferably have a simple, quasi-straight edge end. Holes or openings are provided in the two shorter legs of the U-shape, i.e. on the side of the U-profiles.
    When the frame is mounted on a surface or base frame, the base profile (1) can first be mounted, for example by means of screws, after which other profiles (2, 3) are unfolded.
    After unfolding the intermediate profile (3) is connected to the mounting profile (2), for example by means of a bolt and nut arranged in the profiles through openings (6, 7).
    Unfolding means first unfolding the mounting profile (2) and then unfolding the intermediate profile (3) from the base profile (1). In another embodiment, in which the intermediate profile (3) is folded at the top of the mounting profile (2), unfolding means first unfolding the intermediate profile (3) and then the mounting profile (2).
    Alternatively, the profiles (2, 3) can first be unfolded and connected to each other and then the base profile (1) can be applied to a surface or base frame.
    As shown in Figure 2, the base profile (1) includes side supports (10) along the length of the profile for securely mounting the frame on a surface or base frame. The base frame is then first mounted on the roof or wall structure, while the frame according to the invention is mounted on the base frame. In one embodiment, the base frame takes the form of a rectangular frame.
    Figures 3 and 4 illustrate an embodiment of a mounting profile (2) and an intermediate profile (3), respectively. Figure 3 illustrates a mounting profile (2) comprising three openings (7) for adapting the connection to the intermediate profile (3) at three different angles of 15 °, 20 ° and 30 °.
    In a specific embodiment of a frame according to the invention, openings (6) are provided at the end of the intermediate profile (3). Multiple openings (7) are provided in discrete positions along at least a portion of the length of the mounting profile (2). Each opening corresponds to a different angular position of the mounting profile (2) and thus the solar panel mounted on it.
    Figure 5 is a specific embodiment of a position of the mounting frame at an angle of 30 °. Figure 6 shows a pre-assembled mounting frame of the invention in a specific angle of 25 °.
    In addition to nuts and bolts, other fastening means can be used, such as, for example, a click means mounted on one leg and clickable in a receiving means in the other leg. The click means can even be positioned at different angles.
    As shown in figure 3, the mounting profile (2) comprises fixing means, e.g. openings (11) for fixing a solar panel. Cage nuts can be used for this. Cage nuts are nuts that are clamped in a resilient housing (cage) and that can be clamped in an opening (11) due to the shape of the cage. Once pressed into the opening, the plate material is threaded.
    The mounting profile (2) further comprises elements (12) at the end (4) for mounting on the base profile. These elements (12) are dimensioned such that the connection to the base profile (1) is provided, whereby the wider dimensions of the actual mounting profile (2) can be folded onto said base profile (1).
    The base profile (1) and intermediate profile (3) further comprise one or more recesses (8) and cover lips (9) which are arranged at different positions for applying ballast or other material to it.
    As shown in Figs. 4a to c, the intermediate profile (3) can be made available in different lengths, in order to provide pre-assembled frames that are adapted to different angle ranges. A longer intermediate profile can provide a range of larger angles compared to a shorter intermediate profile. The choice of the length of intermediate profile (3) can depend on the application, which can be for roofs, flat and / or sloping, or walls.
    The profiles are preferably made by punching in a mold of a metal, such as stainless steel or aluminum.
    A pre-assembled mounting frame according to a specific embodiment of the invention comprises an intermediate profile (3) which is slidably (or slidably) arranged in the mounting profile (2), ie the intermediate profile (3) can be fixed relative to the mounting profile (2) at least a portion of the length of the mounting profile (2), preferably in the direction of the open end of said mounting profile (2). To that end, the mounting profile (2) comprises guide means for guiding the end of the intermediate profile (3) along the mounting profile (2), whereby the end of the intermediate profile (3) is slidably connected. As such, the end of the intermediate profile (3) remains positioned in the guide means, both in folded and in unfolded position. This makes on-site assembly easier, since the profiles do not include open or hanging ends. All ends are connected to each other in one way or another. The frame can be assembled with one hand.
    The actual fixing of the intermediate profile (3) with the mounting profile (2) can be provided by a bolt-and-nut system in discrete openings as explained above.
    In a slidable device in which the intermediate profile (3) is slidably arranged along the mounting profile (2), unfolding means raise the mounting profile, wherein the intermediate profile (3) is raised in the same movement. This is the added advantage of a slidable embodiment. Mounting is very easy and could be carried out in one upward movement and one connecting movement, the end of the intermediate profile (3) being attached to the mounting profile (1) by means of e.g. a click system. A nut and bolt can be added as additional fasteners.
    The sliding and snap system can for instance be designed as a longitudinal slot which is partially arranged in the short legs of a U-shaped profile. The end of leg (3) can then move (slide or slide) into the longitudinal slot via a protrusion. The protrusion cannot come out of the slot. The slot can further be provided with notches at fixed positions in which the protrusion of leg (3) can be snapped or deployed. A different angle can thus always be obtained. The gravity and weight of the solar panels keeps the protrusions snapped into the notches. If necessary, bolts and bolts can be used to fasten.
    In another example, the longest leg (2) can have a C-shape. The C-shape is actually a U-shape in which the short legs get an extra blow inwards. In that stroke the shorter leg (3) can slide with an end / protrusion and can be pulled up. The longest leg must then be made slightly wider so that it can still be folded. This allows an even better placement of the panels and also strengthens the leg.
    In a further specific embodiment for connecting the intermediate profile (3) to the mounting profile (2), a continuous fixation can be provided. Instead of providing openings at discrete distances, a friction-based fastening means can be arranged, for example, such that the mounting profile (2) can be continuously positioned by the intermediate profile (3) at any desired angle.
    A pre-assembled mounting frame according to a second aspect of the invention, as shown in Figure 7, provides an adaptable construction of the pre-assembled frame via to the surface profile.
    In the same way as described above, the mounting frame comprises two legs (2 and 3) which are connected via ends (4) to a first leg (1). In this embodiment, however, the "first leg" (1) of the three pre-assembled legs assumes the function of the mounting profile and the "second" leg (2) assumes the function of the basic profile. The "third" leg (3) is the intermediate profile that can be connected to the "second" leg in an adaptable construction. To this end, the basic profile (2) comprises openings (7) at different positions for receiving the intermediate profile (3) and arranging the mounting profile (1) in different angular positions.
    The profiles (1, 2, 3) are arranged in such a way that the intermediate profile (3) can be folded onto the mounting profile (1) and the assembly of these two profiles can be folded onto the basic profile (2) for easy and compact handling. and transport. In the folded position, the pre-assembled frame again assumes the dimensions of the basic profile (2) with an additional thickness of the other two profiles folded at the top (1,3).
    In this embodiment, the base profile (2) or "second" leg comprises side supports (10) along the length of the profile for securely applying the frame to the surface. When mounting on a surface or base frame, preferably a flat surface, the base profile (2) can first be applied to the surface or base frame by means of, for example, screws, whereafter the other profiles (1, 3) are folded out.
    After unfolding, the intermediate profile (3) is connected to the base profile (2) by means of a bolt and nut arranged through openings (6, 7) in the profiles.
    Unfolding here means raising the mounting profile (1), the intermediate profile (3) being raised simultaneously with this movement.
    In the same way as described above for the first aspect of the invention, the intermediate profile (3) can be slidably arranged over at least a portion of the length of the base profile (2). Both profiles (2, 3) can also be connectable to each other by means of either discrete connection points (e.g. openings and nuts and bolts) or by means of continuous fixing (e.g. based on friction).
    In a slidable construction, in which the intermediate profile (3) is slidably arranged along the base profile (2), mounting is very easy and could be carried out in one upward movement and one connecting movement, the end of the intermediate profile (3) at the basic profile (2) is confirmed by means of, for example, a click system. A nut and bolt can be added as additional fasteners.
