Abstract

Profile connecting members for solar panel mounting systems The present invention relates to a solar panel system for a flat roof, more in particular, to versatile connecting members for profiles that are used in solar panel mounting systems comprising matrix-like arrangements of a plurality of base profiles which are interconnected with a plurality of matrix stabilising profiles and/or carrier profiles.

Description

Profile connecting members for solar panel mounting systems
The invention relates to a solar panel system for a flat roof, more in particular, to connecting members for profiles that are used in solar panel mounting systems comprising matrix-like arrangements of a plurality of base profiles which are interconnected with a plurality of matrix stabilising profiles and/or carrier profiles.
The term 'profile' refers to an elongated constructive element, possibly hollow, with a high bending stiffness in relation to its weight.
The carrier profiles may fulfill multiple functions at once: carrying the solar panels and wind diversion plates, being part of the stable construction (i.e. the matrix) and setting the right distance between the base profiles. In the remainder of this description and in the claims only the base profiles and carrier profiles will be mentioned, which does not exclude the applicability of the connecting members according to the invention to profiles with another function that may be used in solar panel mounting systems or other systems. It is inherent to the functions of carrying the solar panels and wind diversion plates of solar panel mounting systems that the carrier profiles are mounted at an inclination angle with respect to the horizontal. The carrier profiles may have a first inclined section that carries solar panels and a second inclined section of which the inclination is opposite to that of the first inclined section to carry wind diversion plates.
The carrier profiles and base profiles often shall be interconnected
perpendicularly through means that prevent relative rotation between the base profile and the respective carrier profile. 'Perpendicularly' refers not only to an angle of exactly 90 degrees but also to slightly deviating angles, such as, for example, 87 or 92 degrees. This perpendicular connection is achieved by using constructive elements capable of transferring a bending force from the base profile to the carrier profile.
The present invention involves a connecting member for making such a connection between a base profile and a carrier profile, capable of transferring a bending force from the base profile to the carrier profile. It also relates to a connecting member that connects a first section of a carrier profile to a second section of a carrier profile. For the sake of simplicity, hereinafter, these two sections of a carrier profile may also be referred to as the first carrier profile and the second carrier profile. The connecting members in accordance with the invention are cost effective both in terms of the use of materials and the use of installation labour.
The connecting members according to the invention will be clarified on the basis of drawings pertaining to preferred embodiments, wherein:
Fig. 1 shows a longitudinal section of a connecting member for the connection of a first section of a carrier profile to a second section of a carrier profile;
Fig. 2 shows a cross section of a base profile with a carrier profile mounted perpendicularly to the longitudinal axis of the base profile;
Fig. 3 shows a perspective view of an assembly;
Fig. 4 shows a cross section of another base profile with a carrier profile mounted perpendicularly to the axis of the base profile.
The preferred embodiments shown in these drawings are solely shown as an illustration of the invention and not in limitation thereof.
Fig. 1 shows a longitudinal section of a connecting member, depicted by the bold black structure, connecting a first section of a carrier profile 1 to a second section of a carrier profile 2. The two sectioned walls of each of the profiles 1 and 2 are shown as sets of fully drawn lines. The drawing also shows that the same connecting member can be used to make an assembly of two profiles 3 and 4, of which the sectioned walls are depicted by dotted lines, with a significantly different angle relative to the junction plane 6 than the angle of the profiles 1 and 2 relative to the junction plane. Hence, this connecting member provides a very versatile solution for connecting two profiles in a continuous range of possible angles, for both profile sections independent from each other. Hereinafter, the connecting member shown in fig. 1 may also be referred to as the 'knee'.
The knee comprises a combination of two hollow wedge shaped sections 7 and 8 of which the first wedge shaped section 7 is inserted in the open slanted end of the first carrier profile 1 and the second wedge shaped section 8 is inserted in the open slanted end of the second carrier profile 2. Each of the wedge shaped sections of the knee has means 9 through which a fastener can be guided or in which a fastener can be fixed in order to attach that section to the respective carrier profile section. In this case, attaching the knee to a profile requires two holes matching the positions of the means 9 in the relevant knee section to be drilled through the profile. The fasteners that are used for this purpose can include, for example, rivets, self-tapping screws or self-drilling screws. In order to assure that the slanted edges of the first and the second carrier profile are positioned correctly to meet at the junction plane 6 the knee comprises a shoulder 10. Unlike the knee shown in fig. 1, which is hollow, the knee according to the invention can also have a solid body. When using a knee without preformed or pre-drilled holes for fasteners, the use of self-drilling screws may save installation time.
The preferred positioning of the first and the second carrier profile in order to connect them in the way shown in fig. 1 using a knee involves ensuring that the top side of the first carrier profile 1 coincides with the top side of the second carrier profile 2 at the junction plane and assuring that the bottom edge of the first carrier profile 1 rests against the shoulder 10. Of course, the two carrier profiles can be joined in many other ways, depending for example on their cross-sectional shape and dimensions and on the desired angle between the two profiles. In selecting the length and the wall thickness of the wedge shaped sections of the knee a compromise is necessary between the required capability to transfer a bending force, the ability to accommodate a wide variety of angles between the profiles that have to be connected with each other and a limitation of the weight of the knee with the pertaining limitation of the material cost. The shape of the wedges, including the lengths and the inclination of the sides of the wedges and the relative angle between the two wedge shaped sections of the knee is selected such that one knee configuration can be used to obtain carrier profiles with a wide variety of angles between the first carrier profile and the second carrier profile. Although the wedge is a preferred shape for a section of the connecting member according to the invention, the invention includes connecting members with sections that have other shapes that allow a connection to be made with an open end of a profile with a wide continuous range of possible angles. Such shapes may include, but are not limited to, for example a partially circular shape or a polygon.
Fig. 2 is a cross section of a connection between a base profile 11 and a slanted end of a carrier profile 12. Similar to the connection of the knee, the
embodiment of the connecting member according to the invention that is shown by the bold black structure in fig. 2 is connected to the carrier profile 12 by inserting a wedge shaped section of the connecting member in the open slanted end of the carrier profile and by attaching the wedge to the profile by means of, for example, rivets or screws. In order to connect the carrier profile perpendicularly to the base profile the connecting member comprises a head section 13 at the end of the connecting member opposite to the end with the wedge shaped section. This hollow head has one vertical bearing surface 14 which may bear against a side wall of the base profile 11.
The top side of the head of the connecting member has a groove 15 and the bottom side of the flange has a groove 16. Both of these grooves have a wedge shaped cross section. In the embodiment of the base profile shown In fig. 2 the base profile has a base plate 17 which is wider than the hollow body section of the profile. The base plate has a stiffening rib on each side of the body of the profile whereby the dimensions and the wedge shaped cross section of the stiffening ribs make it possible to lower the head with the groove 16 onto a stiffening rib. In this way the head can neither move away from the base profile laterally nor can it rotate horizontally. However, without any further measures the head can easily be lifted and then move away.
So, in order to ensure a firm and rigid connection of the carrier profile perpendicularly to the base profile the head section of the connecting member has to be locked up. Hence, a lock-up plate 18 is placed on top of the body of the base profile, whereby the lock-up plate comprises at least one wedge shaped downward facing edge which fits in the wedge shaped groove 15 of the head of the connecting member. The lock-up plate is attached to the base profile by means of at least one bolt 19 and nut 20. The nut is located inside a recess in the base profile which extends over the entire length of the base profile and has a slot at the top side of the body of the base profile along the entire length of the base profile. By fixing the lock-up plate to the top side of the body of the base profile with the bolt and nut as shown in fig. 2 the wedge shaped, downward facing edge of the lock-up plate is pressed inside the wedge shaped groove 15 of the head of the connecting member. In this way the head of the connecting member is pressed between the base plate 17 and the lock-up plate 18. Although the lock-up plate 18 shown in fig. 2 only connects a carrier profile to one side of the base profile this embodiment of the lock-up plate can serve to attach carrier profiles to either side of the base profile.
Disassembling the connection that is shown in fig. 2 will only require slackening of the bolt 19 which will allow the lock-up plate to slide along the base profile in the longitudinal direction of the base profile. This will allow the head of the connecting member to be lifted and the assembly to be disassembled as will become clear by looking at fig. 3, which shows a perspective view of a base profile, similar to the one showed in cross section in fig. 2, with a carrier profile mounted on one side of the base profile.
The embodiment of the lock-up plate shown in fig. 3 has two bolts. The lock-up plate according to the invention can have any number of bolts deemed necessary and/or practical.
While the base profile shown in fig. 2 and 3 has a base plate with stiffening ribs, the connecting member according to the invention can also be applied for the connection of carrier profiles to a base profile without a base plate and stiffening ribs, for example to a base profile having a plain rectangular cross section. In such a case a lock-up plate with at least one edge pointing upwards that fits in the groove 16 at the bottom of the head of the connecting member is placed underneath the bottom of the base profile. Depending on whether a recess is present along the bottom of the base profile the lock-up plate at the bottom of the profile can be attached in the same way in which the lock-up plate at the top side of the profile shown in fig. 2 is attached. Otherwise, the lock-up plates can be pressed to respectively the bottom and the top side of the base profile body by at least one long bolt which extends through the entire package consisting of the lock-plate at the top, the base profile body and the lock-up plate at the bottom of the base profile. Disassembling such an
embodiment of an assembly of a base profile with one or two carrier profiles connected to the base profile, using a connecting member according to the invention, does not require the bolt to be removed completely, if the lock-up plates are attached with only one bolt. In such a case, slackening of the bolt sufficiently to allow lifting and rotating the lock-up plate at the top
approximately 90 degrees will allow the head of the connecting member to be lifted and removed from the edge of the lock-up plate at the bottom of the base profile.
Although it has not been discussed in this descriptive section or shown in drawings the connecting member according to the invention offers the possibility to make a rigid connection between a carrier profile and a base profile which is not necessarily a perpendicular connection. If a connecting member comprising a wedge shaped section and a head section is
manufactured such that the head is positioned at an angle relative to the plane that is formed by the wedge shaped section, this connecting member can make connections whereby the angle between the longitudinal axis of a carrier profile and the longitudinal axis of a base profile may differ significantly from 90 degrees.
In this descriptive section the terms connect, connecting or connection can refer to both detachable and permanent ways of joining profiles and other structural elements.
All examples given in this descriptive section are intended to be non-limiting, and are provided in order to help in conveying the scope of the invention.
