Description

Title of the invention: PART FOR FIXING A RAIL TO A PROFILE Technical field

[0001] The present disclosure relates to a fixing part, and more particularly to a part for fixing a rail to a profile. Such a part finds its application in particular for fixing equipment to roof or shade profiles, for example solar or photovoltaic panels mounted by means of rails. Prior art

[0002] Fixing equipment on roofs or shade structures, such as solar panels, is a recurring need. Solar panels are often mounted on dedicated rails, and fixing these dedicated rails to the roof or shade structure generally requires that the rail be specially adapted to the roof or shade structure on which it is to be fixed. This limits the compatibility of the equipment with certain types of roof or shade structure.

[0003] There is therefore a need for a new type of fixing part. Statement of the invention

[0004] For this purpose, the present disclosure relates to a part for fixing a rail to a profile, comprising a base configured to bear against the profile, a bearing portion configured to bear against the rail so as to clamp the rail against the profile, the base and the bearing portion being inclined relative to each other and connected to each other by at least one arm configured to transmit the forces between the base and the bearing portion, the part defining, between the base and the bearing portion, a slot configured to receive at least a portion of the rail or the profile.

[0005] As previously indicated, the rail may be configured to receive equipment such as a solar panel, while the profile may belong to or be mounted on a roof or a shade.

[0006] Since the base and the support portion are inclined relative to each other, they are neither parallel nor perpendicular to each other. They therefore form an angle strictly between 0° and 90°. The inclination makes it possible to adjust the forces exerted by the support portion on the rail by translating the base and therefore allows fine control of the clamping between the rail and the profile.

[0007] In this disclosure, and unless otherwise indicated, by "a" or "the" arm (or any other element), we mean "at least one" or "the at least one" or even "each" arm. Conversely, the generic use of the plural can include the singular.

[0008] The slot receives at least a part of the rail or profile, that is to say at least one part of the rail and / or at least part of the profile.

[0009] The proposed part, also called a fixing part, therefore forms a simple component whose slot can be designed to receive different types of rails, and which ensures good clamping of the rail on the profile. The part therefore provides a generic fixing interface between the rail and the profile, and provides both simplicity and flexibility.

[0010] In some embodiments, the base is configured to attach to the profile. The part can thus be better held.

[0011] More specifically, in some embodiments, the base is configured to attach to the profile in a position such that the base transmits to the bearing portion, via the at least one arm, forces by which the bearing portion clamps the rail against the profile. For example, the part may first be positioned on the assembly of the rail and the profile, the base then being in a so-called loose position such that the bearing portion rests on the rail without clamping the rail. The base may be brought into a clamping position and fixed to the profile in this position; in the clamping position, the base is moved relative to the loose position so as to transmit forces to the arm and then to the bearing portion, these forces inducing clamping of the rail on the profile by the bearing portion. For example, the arm may be placed in tension or in flexion, which induces compression between the bearing portion and the rail, then between the rail and the profile.Other force transmission chains are possible; for example, the arm can be put into compression to press, via the support portion, the rail against the profile.

[0012] In some embodiments, the part is formed from a cut and folded metal sheet. The part is therefore particularly simple to obtain and inexpensive.

[0013] In certain embodiments, the base comprises, at least at the level of its attachment to the profile, several thicknesses of the metal sheet. The attachment of the base to the profile is therefore reinforced, without this complicating the manufacture of the part.

[0014] In some embodiments, the base is formed by at least one flap of the metal sheet. The position of the base relative to the profile can therefore be adapted with greater flexibility. Where appropriate, one or more flaps also make it easier to superimpose several thicknesses of the metal sheet.

[0015] In certain embodiments, said flap is beveled beyond the attachment of the base to the profile. This lightens the part, or even limits the size of the base in certain configurations, without affecting the performance of the part in terms of attachment and mechanical strength.

[0016] In certain embodiments, the at least one arm comprises two arms, each at one of the lateral ends of the part. The transmission of forces between the base and the support portion is therefore well distributed.

[0017] In certain embodiments, the at least one arm has a mechanical reinforcement such as a rib. The arm therefore has better mechanical strength. The rib can be obtained by stamping, which remains compatible with the cutting and folding method mentioned above.

[0018] In some embodiments, the part comprises at least one grounding tab, projecting from the part towards the slot in order to come into contact with the rail. Particularly, the tab may project from the bearing portion. The tab may be flexible in order to maintain good electrical contact regardless of the relative position of the bearing portion and the rail. Alternatively, the tab may be rigid.

[0019] In some embodiments, the bearing portion comprises a platform extending along the rail and configured to bear against the rail. The platform therefore has a long bearing surface against the rail, which makes it possible to distribute the forces and to prevent the clamping of the bearing portion against the rail from deforming the rail, especially when the rail is made of a soft material such as aluminum. For example, the rail extending in a longitudinal direction, the rail or the profile is inserted into the slot in an insertion direction transverse to the longitudinal direction and the clamping forces on the rail are exerted in a clamping direction transverse to the longitudinal direction and to the insertion direction. The platform may extend in the longitudinal direction, i.e. transversely to the insertion direction.The platform may be substantially flat, or more generally have a shape that matches the shape of the rail against which it rests.

[0020] In some embodiments, the platform extends along the rail over a length greater than the width of the base. The length is defined along the longitudinal direction. The width of the base is the largest dimension of the base transverse to the longitudinal direction; due to the inclined nature of the base relative to the bearing portion, the width of the base may comprise a component along the insertion direction and a component along the clamping direction.

[0021] Thanks to the fact that the length of the platform is greater than the width of the base, the forces on the rail are even more distributed, which results in better support while further limiting deformations of the rail.

[0022] In some embodiments, the arm extends on either side of the platform. The arm is therefore more rigid and its junction with the platform is made on a side opposite the platform, which limits the risk of tearing which would occur if the arm joined the platform directly at the slot, where the platform exerts forces against the rail.

[0023] In some embodiments, the arm extends from the base to an angled return for connecting the arm to the platform, the angled return being provided on one side of the platform opposite the base. The elbow return includes at least one elbow to make the junction between the arm and the support portion.

[0024] In some embodiments, the angled return does not protrude from the platform toward the slot. Thus, the angled return does not interfere with the platform pressing against the rail.

[0025] In certain embodiments, the part comprises at least one portion extending into the slot, between the support portion and the base, said portion forming a counter-support for the rail. The support portion and the counter-support portion are therefore intended to be mounted on either side of the rail and to press on opposite faces of the rail. The counter-support portion makes the mechanical mounting and the electrical contact of the fixing part with respect to the rail more reliable.

[0026] The present disclosure also relates to a solar panel mounting assembly, comprising a profile and at least one part for fixing a rail to the profile as described above. According to another embodiment, the solar panel mounting assembly comprises a rail and at least one part for fixing the rail to a profile as described above. The part may have all or some of the features disclosed. Brief description of the drawings

[0034] A fixing part 10 according to a first embodiment is described with reference to FIGS. 1 and 2.

[0035] The fixing part 10 is intended to allow the fixing of a rail, such as a rail of mounting of a solar panel, on a profile, such as a roof or shade profile.

[0036] The fixing part 10 comprises a base 20, a support portion 30 and at least one arm 40, in this case two such arms 40. The base 20 and the support portion 30 are inclined relative to each other and define, between them, a slot 50.

[0037] The fixing part 10 may be provided with an orthogonal reference mark (X, Y, Z), where the longitudinal direction X is the direction in which the rail extends, the insertion direction Y is the direction in which the profile and / or the rail is inserted into the slot 50, and the clamping direction Z is the direction in which the fixing part 10 clamps the rail against the profile.

[0038] The arms 40 connect the base 20 to the support portion 30. In this case, the fixing part 10 is formed in one piece, the arms 40 being integral with the base 20 and the support portion 30.

[0039] More particularly, the fixing part 10 can be formed from a cut and folded sheet: a pattern is cut from a sheet, and this pattern is then folded to give the fixing part its final shape. For example, from the support portion 30, the sheet can be folded to form the arms 40, and the end of these arms 40 can be folded to form the base 20. Thus, the base 20 can be formed by at least one flap 22 of the sheet.

[0040] In this case, as can be seen from [Fig.l], the base 20 comprises several sheet thicknesses. The base 20 may be formed by two flaps 22 which overlap at least in part, each flap 22 being connected to one of the arms 40.

[0041] The fixing part 10 may be made of any material sufficiently rigid to ensure good fixing of the rail on the profile, for example metal. Thus, the aforementioned sheet may be a metal sheet. For example, the fixing part 10 is made of steel, optionally galvanized or provided with an anti-corrosion coating.

[0042] The base 20 may be configured to attach to the profile. For this purpose, in the present embodiment, the base 20 may be provided with an orifice 24 for the passage of a screw which will be described later. If necessary, other attachment means may however be provided.

[0043] According to [Fig.l], the base 20 may comprise several thicknesses of the metal sheet from which it is made at least at the level of its fixing on the profile, that is to say here at least at the level of the orifice 24. As shown in [Fig.l], beyond this fixing, that is to say here beyond the orifice 24, the flaps 22 may be beveled; more generally, the base 20 may have, in places, only a single thickness of metal sheet.

[0044] For example, a bevel 26 may be provided between a free end 26a of a flap 22 and a lateral portion 26b of the flap 22, the lateral portion 26b optionally being located beyond the orifice 24, i.e. closer to the free end 26a than hole 24.

[0045] In this embodiment, the base 20 extends over the entire length L1 of the part 10 in the longitudinal direction X. Apart from the various flaps 22 which may be superimposed and / or bevelled, the base 20 may be substantially flat, or more generally have a shape configured to match a corresponding shape of the profile. Transversely to the longitudinal direction X, the base 20 extends over a width W having a non-zero component in the insertion direction Y and a non-zero component in the clamping direction Z.

[0046] The bearing portion 30 is configured to bear against a rail so as to clamp this rail against the profile. It is normally the part of the bearing portion 30 which projects the most towards the slot 50 which comes into contact with the rail itself.

[0047] In this case, the support portion 30 thus comprises a platform 32 configured to come into contact with the rail. The platform 32 extends along the rail, that is to say in the longitudinal direction X. The platform 32 may be substantially planar, or more generally have a shape configured to match a corresponding shape of the profile. In addition to the longitudinal direction X, the platform 32 may extend along the insertion direction Y.

[0048] In the longitudinal direction, the platform 32 can extend over a length L2 greater than the width W of the base 20. As will be seen later, this ensures good distribution of the forces.

[0049] Optionally, the platform 32 may be provided with a hole 34. The hole 34 may have any desired function, for example the attachment of a collar intended to hold the electrical cables of the photovoltaic panel intended to be mounted on the rail.

[0050] Particularly for electrical applications, the fastening part 10 may comprise at least one grounding tab 36. The tab 36 projects from the fastening part 10 towards the slot 50. For example, as illustrated in [Fig.l], the tab 36 may project from the platform 32, in order to ensure its contact with the rail. In this embodiment, the tab 36 is a portion of the platform 32 which has been partially cut and bent in order to exit the plane of the platform 32.

[0051] Each arm 40 connects the support portion 30 to the base 20, more precisely here to one of the flaps 22. Each arm 40 can be provided at a lateral end of the fixing part 10 in the longitudinal direction X.

[0052] The arms 40 are here generally L-shaped, the inside of the L opening onto the slot 50. Thus, the arms 40 do not hinder the insertion of the rail and / or the profile into the slot 50.

[0053] The arms may extend transversely to the longitudinal direction X. In this case, the arms 40 may extend mainly in the YZ plane, or even be substantially flat in the YZ plane.

[0054] As will be discussed in detail with reference to [Fig. 2], the arms 40 are configured to transmit forces between the base 20 and the support portion 30. In order to mechanically reinforce them, the arms 40 may have a mechanical reinforcement 42 such as a rib. In the example of [Fig. 1], the rib is obtained by stamping the arm 40, if necessary before cutting and / or folding the starting metal sheet. However, other types of reinforcement may be provided, for example by adding material, extra thickness or others.

[0055] In this embodiment, the arms 40 extend on either side of the platform 32. More specifically, the arms 40 extend from the base 20, around the slot 50 and extend beyond the platform 32. The end of each arm 40 distant from the base 20 may have an angled return 44 to connect the arm 40 to the platform 32, the angled return 44 being provided on a side of the platform 32 opposite the base 20.

[0056] According to one example, the elbow return 44 may comprise a first elbow 45, a junction portion 46 and a second elbow 47, connecting, in this order, the arm 40 to the platform 32. The first elbow 45 follows a hairpin contour (for example approximately 180°, + / - 45°) and ends at a junction portion 46 which is substantially parallel to the arm 40. The second elbow 47 has an inverted concavity relative to the first elbow, in order to connect the junction portion 46 to the platform 32, here in a curved and progressive manner.

[0057] The platform 32 is here provided longitudinally between the two arms 40, and a fortiori between the two corresponding elbow returns 44. However, other arrangements are possible, in particular if the number of arms 40 is other than two.

[0058] It is noted that the angled return 44 does not protrude from the platform 32 in the direction of the slot 50, which avoids point pressure on the rail.

[0059] [Fig.2] shows, in section, a fixing assembly 100 for a solar panel.

[0060] The fixing assembly comprises a profile 60 as well as a fixing part 10 as previously described. As mentioned previously, the profile 60 is intended to be fixed to a roof or a shade and to serve as a support for a rail 70 for mounting equipment such as a solar panel.

[0061] In this embodiment, the profile 60 has a general omega shape, however other shapes are conceivable. In any event, the profile 60 comprises a base surface 62, against which the base 20 is configured to bear, and a receiving surface 67, forming a support for receiving the rail 70. The base surface 62 and the receiving surface 67 may be inclined relative to each other, in particular by the same angle as that formed by the base 20 relative to the bearing portion 30. The angle between the base surface 62 and the receiving surface 67 may be, in particular, an angle strictly between 0 and 90°.

[0062] The base surface 62 and the receiving surface 67 may be contiguous or, as here, separated by a bead 64. The bead 64 can protrude relative to at least one of the base surface 62 and the receiving surface 67. In this case, the bead 64 makes it possible to lengthen the receiving surface 64.

[0063] A screw 80, for example a self-drilling screw, may be provided to fix the base 20 to the profile 60. In this case, the screw 80 is inserted into the orifice 24 and into a corresponding thread of the base surface 62, in order to tighten the base 20 against the base surface 62.

[0064] Furthermore, the rail 70 comprises a frame 72, here with a rectangular section; however, any other shape or size could also be suitable, depending on the equipment to be fixed. The frame 72 is provided, on the one hand, with mounting means 74, and on the other hand, with a base 76. The mounting means 74, here taking the form of an open rail, can adopt any ad hoc shape for mounting the desired equipment, for example a solar panel. Furthermore, the base 76 is intended to be received on the receiving surface 67. In this embodiment, the base 76 extends a face of the frame 72, towards the outside of the profile, which increases the contact surface between the rail 70 and the profile 60 and provides greater stability.

[0065] The base 76 therefore comprises an internal face 76a configured to be in contact with the profile 60, more particularly with the receiving surface 67. The opposite face of the base 76, called the external face 76b, is configured to be in contact with the support portion 30 of the fixing part 10.

[0066] As shown in [Fig.2], the support portion 30 may be set back from the base 20 in the insertion direction Y, or in any case not protrude beyond the base 20. This allows the fixing part 10 to be used for different types of rails, including those in which the frame 72 is wider than that shown in [Fig.2].

[0067] [Fig. 2] illustrates the mounting of the rail 70 on the profile 60 and its holding by the fixing part 10. Once the rail 70 is placed on the profile 60, more precisely the base 76 placed on the receiving surface 67, the fixing part 10 can be arranged so that at least a portion of the rail 70 or of the profile 60 is inserted into the slot 50. In this case, in the configuration of [Fig. 2], the slot 50 accommodates the base 76 of the rail 70 and a portion of the bead 64 of the profile 60. In this configuration, the base 20 bears against the profile 60, more precisely against the base surface 62, while the bearing portion 30, more particularly the platform 32, bears against the rail 70, more precisely the base 76.

[0068] At this stage, the fixing part 10 may be in a so-called loose position and not take up any particular force. The alignment between the orifice 24 of the base 20 and the thread of the profile 60 may be such that by screwing the screw 80, the base 20 is slightly lowered (or more generally moved away from the rail 70). If necessary, the flexibility of the base 20 may be improved by the presence of the flaps 22, one end 26a of which is free.

[0069] The fixing of the base 20 on the profile 60 is such that the base 20 then transmits to the support portion 30, via the arms 40, forces by which the support portion 30 clamps the rail 70 against the profile 60. More precisely, the lowering of the base 20 towards a clamping position induces a tension in the arms 40. This tension results in compression forces of the bent return 44 on the platform 32. However, the base 76 being located in the slot 50, these compression forces press on the base 76 and therefore ensure the maintenance of the rail 70 relative to the profile 60.

[0070] From this point of view, the platform 32 offers a large support surface which makes it possible to distribute the forces evenly and therefore not only to ensure more stable support but also to avoid damaging the rail 70.

[0071] The support of the support portion 30 against the rail 70 can cause the flexible grounding tabs 36 to retract, in particular into the space that they occupied before cutting and folding, while maintaining contact with the rail 70.

[0072] Figures 3 to 6 show the fixing part 10 in other embodiments. In these figures, the elements corresponding or identical to those of the first embodiment will receive the same reference sign and will not be described again.

[0073] With reference to [Fig. 3], the fixing part 10 according to the second embodiment differs from that of the first embodiment in particular by the fact that the platform 32 is not intended to come into contact with the rail 70. On the contrary, the platform 32 connects the respective ends of the arms 40, without an angled return, and the support on the rail 70 is allowed by lugs 33 which project from the platform 32 in the direction of the slot 50. This also requires a longer grounding tab 36, although its composition is, in principle, unchanged.

[0074] Furthermore, the support on the rail 70 being punctual at the level of the lugs 33, the longitudinal dimension of the fixing part 10 is less important than in the first embodiment and can be reduced, for reasons of lightening.

[0075] Furthermore, the flaps 22 may be devoid of bevels.

[0076] With reference to [Fig. 4], the fixing part 10 according to the third embodiment differs from that of the first embodiment in particular by the fact that the flaps 22 have a system 23 for holding them in position relative to each other. In this case, the system for holding them in position 23 comprises projections / recesses cooperating from one flap 22 to the other in order to prevent the flaps 22 from pivoting relative to each other under the effect of the tightening of the base 20, it being understood that the screw 80 already prevents the translations of the flaps 22 relative to each other. For example, as illustrated in [Fig. 4], one of the flaps 22 may comprise at least one bulge projecting towards the other flap 22, this other flap 22 comprising as to it at least one slot configured to receive said bulge. Bulge and slot can be obtained by cutting and / or stamping, which does not complicate the manufacture of the fixing part 10. However, any other system of interlocking or coincidence can be envisaged. In particular, in a variant, the flaps 22 can be assembled and held in a desired position by clinching. The position holding system 23 can then comprise a clinching zone. The clinching zone results from a clinching operation, also called assembly-stamping, and has projections fitted into each other in order to assemble the corresponding flaps 22 to each other.

[0077] Furthermore, instead of projecting from the platform 32, the grounding tab 36 here projects from at least one of the arms 40, here the two arms 40, and more particularly from a portion 43 of the arm 40 at the interface with the angled return 44. The grounding tab 36 may be provided at one end of the arm 40 on the side of the base 20, in the insertion direction Y. So that the grounding tab 36 reaches the rail 70, the aforementioned portion 43 may be elongated relative to the angled return 44, in the insertion direction Y, towards the base 20. In this case, the portion 43 is elongated so as to extend towards the rail 70 as much as the platform 32 in the insertion direction Y.

[0078] The grounding tab 36 may be rigid, for example provided in the form of one or more claws on each arm 40 concerned, projecting relative to the arm 44 in the direction of the slot 50. These claws or notches may be cut at the same time as the entire fixing part 10, thereby making manufacturing simple. Optionally, the claws may be beveled in a direction facilitating the insertion of the fixing part 10 onto the rail 70 and limiting the removal of the fixing part 10, the claws biting into the material of the rail 70.

[0079] Figures 5 and 6 illustrate a fixing part 10 according to a fourth embodiment. As shown in these figures, the fixing part 10 according to the fourth embodiment differs from the previous embodiments in that it comprises at least one portion 52 extending into the slot 50, between the bearing portion 30 and the base 20, the portion 52 forming a counter-support for the rail 70. In particular, the spacing between the counter-support portion 52 and the bearing portion 30 may be less than the thickness of the rail 70. Thus, when the rail 70 is inserted between the bearing portion 30 and the counter-support portion 52, the rail 70 is in firm contact with at least one of these portions, generally with both, which improves the electrical transmission between the rail 70 and the fixing part 10.

[0080] In addition, the counter-support portion 52 makes it possible to facilitate and make more reliable the positioning of the fixing part 10 on the rail 70 and the profile 60. This makes it possible to overcome any manufacturing inaccuracies (particularly bending) or mounting the fixing part 10.

[0081] In the example shown in Figures 5 and 6, the fixing part comprises two counter-support portions 52, each projecting from an arm 40 towards the slot 50. The portion 52 here takes the form of a tab extending mainly in the insertion direction Y. At its junction with the arm 40, the tab may have a locally reduced thickness, in particular in the tightening direction Z, in order to provide the portion 52 with flexibility in rotation in the YZ plane. The tab can thus deform during insertion of the rail 70. For example, the locally reduced thickness can be obtained by means of a recess 52a. The recess 52a can be provided on the side of the base 20. The portion 52 may have an increasing thickness from the arm 40 to its free end 52b.The free end 52b may be set back relative to the free end of the support portion 30 and / or the portion 43 of the arm in the insertion direction Y, so as not to interfere with the profile 60 during assembly.

[0082] To facilitate the insertion of the rail 70, the free end 52b, opposite the arm 40, may have a rounded shape (referred to as the entry radius) or beveled, in particular on its portion opposite the support portion 30.

[0083] Furthermore, the grounding tab 36 is provided here in a recess 43a of the portion 43 of the arm 40. The grounding tab 36 can be provided in the form of a claw, here symmetrical in the insertion direction Y unlike the previous embodiments. The recess 43a allows the grounding tab 36 to be longer, therefore more flexible. This also promotes point contact between the portion 43 and the rail 70, here via the grounding tab 36, which avoids hyperstatic mounting of the fixing part 10 relative to the rail 70.

[0084] A deflector 43b may be provided at the free end of the portion 43 to facilitate the insertion of the rail 70 into the slot 50 and to prevent the rail 70 from butting against the grounding tab 36. The deflector 43b may take the form of a bulge in the direction of the slot 50, the edges of which are optionally rounded or beveled to further facilitate the insertion of the rail 70.

[0085] The end of the grounding tab 36 protrudes from the platform 32 towards the slot 50, in order to ensure good electrical contact between the rail 70 and the fixing part 10.

[0086] The mounting of the fixing part 10 according to the second embodiment, the third embodiment or the fourth embodiment can be done as explained for the first embodiment with reference to [Fig.2], mutatis mutandis.

[0087] Although the present description refers to specific exemplary embodiments, modifications may be made to these examples without departing from the general scope of the invention. Furthermore, individual features of the various embodiments illustrated or mentioned may be combined in embodiments additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than restrictive sense.
