Description

[Technical field]

[0001] The present invention relates to the field of fastening means, more particularly to means for fastening panels, for example solar panels, to rails.

[0002] In particular, the invention relates to a holding part and a clamping element which allows a panel to be fixed to a rail. In particular, the holding part and the clamping element are configured to allow a panel to be clamped against a rail. [Background technology]

[0003] US 9160273 discloses a fixing kit for fixing panels, in particular solar panels, to rails. In this respect, as shown in Figure 7 of US 9160273, the fixing kit comprises a holding element 31, a bolt 30 and a sliding element 1.

[0004] In operation, the assembly formed by these three elements is placed between two adjacent panels resting on the rail 8. More specifically, the assembly comprises, in order from the rail, the sliding element 1, the bolt 30 and the retaining element 31. The retaining element 31 comprises a metal plate with opposing edges, called retaining edges, each edge intended to be clamped and retained against the upper peripheral part 36 of the frame of two adjacent panels. The sliding element 1 is in sliding connection with the rail 8, the bolt 30 making it possible to ensure the clamping of the two retaining edges. In particular, the bolt 30, which passes through the retaining element, is screwed into a tapped hole at the top of the sliding element 1 in order to allow the retaining element to be clamped against each of the two adjacent panels.

[0005] However, this fixing kit, which implements a clamp by means of bolts or screws, is not satisfactory.

[0006] Indeed, the bolts may loosen over time, for example under the influence of temperature changes. This loosening has the effect of reducing the holding force exerted by the retaining element on the panel, which may ultimately lead to separation of the panel from the rail. The grip of adjacent panels on the rail may also be reduced due to the ripple effect, with the result that the panel may come off the rail.

[0007] Furthermore, the sliding elements, which are very inaccessible, are difficult to replace when necessary.

[0008] EP 2 867 541 proposes a fastening device that makes it possible to overcome these problems. This fastening device is in particular an integral device and is equipped with snap-fastening means intended to cooperate with the rail. Nevertheless, implementing this fastening device requires taking into account a relatively wider and therefore more expensive rail, in order to allow easier removal when the situation requires it.

[0009] It is therefore one object of the present invention to provide a retaining component, clamping element, and mounting kit that allows for permanent clamping of a panel to a rail.

[0010] Another object of the present invention is to provide a holding part, a clamping element and an installation kit in which the supporting forces are better distributed.

[0011] Another object of the present invention is to provide a holding part, a clamping element and a mounting kit which allow rails of reduced width to be taken into account.

[0012] Another object of the invention is to propose a holding part, a clamping element and an installation kit which remain easy to remove with respect to the known devices of the prior art. Summary of the Invention

[0043] The present invention relates to a preformed integral holding part of a mounting kit intended to hold a panel, for example a solar panel, on a rail. More specifically, the holding part is intended to hold a panel clamped against a rail by one of its faces, called the contact face.

[0044] In this regard, the retaining part is a main part extending along an extension axis A and comprising a first side wall, the first side wall having a first inner surface and a first outer surface and a first upper edge parallel to the extension axis A and facing a rear surface of the main part, the main part further comprising two transverse walls perpendicular to the extension axis and defining a passage opening through the rear surface for insertion of a clamping element of a mounting kit, the transverse walls further comprising a retaining edge defining a retaining plane facing the rear surface, the clamping element inserted through the rear surface being intended to exert a force on the retaining edge in the direction of the rear surface; a first lateral wing extending laterally over its main part from the first upper edge, the first lateral wing intended to be supported by a support surface against an active surface of the panel opposite the contact surface.

[0045] The invention also relates to an integral clamping element intended to cooperate with the retaining part to clamp the panel by its contact surface against the U-shaped section rail. In these respects, the clamping element comprises two uprights mechanically fixed to each other, the uprights each extending in two divergent directions from a first end to a second end in a plane P. The first ends are arranged to allow the clamping element to be attached to the rail by snap-fastening, the second ends each comprising a lateral abutment intended to cooperate with one of the retaining edges when the two uprights are inserted into the passage through their rear faces.

[0046] The invention also relates to a mounting kit comprising a holding part and a clamping element.

[0047] Finally, the invention also relates to a mounting system comprising at least one mounting kit and at least one rail, in particular a U-shaped section rail.

[0048] FIG. 1 shows a first embodiment of a one-piece carrier piece 100 according to the invention.

[0049] The holding part 100 has a front surface 101 and a rear surface 102 opposite the front surface.

[0050] The retaining piece 100 comprises a main part 110 extending along an extension axis A. In particular, the main part 110 comprises a first side wall 111 comprising two substantially parallel faces, referred to respectively as a first inner face 112 and a first outer face 113. Although not necessary to specify, it is understood that the first side wall 111 forms a plane defined by an axis parallel to the extension axis A and by another axis advantageously perpendicular to the extension axis A.

[0051] The first side wall 111 also comprises a first upper edge 114 A extending parallel to the elongation axis A and facing the rear face 102 of the holding piece 100 .

[0052] The main part 100 also comprises two transverse walls 118A and 118B perpendicular to the extension axis A. The two transverse walls 118A and 118B define a passage opening through the rear face 102 for the insertion of a clamping element of a mounting kit. The transverse walls 118A and 118B further comprise retaining edges 119A, 119B forming a retaining plane facing the rear face 102, such that a clamping element inserted in the passage through the rear face 102 is intended to exert a force against the retaining edges in the direction of the rear face 102.

[0053] Each transverse wall 118A and 118B can include a tip, referred to as a contact tip 126, that projects relative to the retaining plane (FIG. 4).

[0054] Advantageously, the transverse walls 118A and 118B extend from the first inner surface 112. However, the invention is not limited to this embodiment, and the skilled person can consider the transverse walls 118A and 118B each extending from a beam 127 perpendicular to the first side wall 111. In particular, these beams can extend from the first upper edge 111A and the opposite first lower edge 114B of the first side wall 114.

[0055] The retaining piece 100 may comprise a wedge 128 linked to the beam 127. The wedge 128 extends the beam 127, in particular by one of its ends facing the first lower edge 114B, and projects relative to the rear face 102.

[0056] Advantageously, transverse walls 118A and 118B each include surfaces, referred to as guide surfaces 120A and 120B, that face each other and define a passageway that opens through rear face 102 (FIGS. 1 and 2).

[0057] 2, each guide surface 120A and 120B includes, from its retaining edge 119A and 119B to an edge opposite the retaining edge, referred to as the entry edge, a retaining section 121, a guide section 122, and an entry section 123. The guide section 122 is flat and perpendicular to the axis of extension, and the entry section 123 is convex so as to limit any contact between the clamping element and the rim of the entry edge during insertion of the clamping element into the passage through the rear surface 102.

[0058] Advantageously, the retaining section 121 is also convex and the retaining plane is not perpendicular to the guide section 122. This arrangement should allow a better grip of the clamping elements described below.

[0059] The retaining piece 100 further comprises a first lateral wing 116 extending laterally of the main part 110 from the first upper edge 114A. The first lateral wing 116 is intended in particular to be supported by a support surface 117 against a working surface of the panel opposite the contact surface of the panel. It will be understood that the support surface 117 of the first lateral wing 116 faces the front surface 101.

[0060] The first lateral wing 116 is preferably flat. However, the invention is not limited to this embodiment, and a person skilled in the art can consider a first lateral wing 116 that is not flat, and more specifically is curved. For example, the first lateral wing 116 has a convex shape through the front surface.

[0061] It is understood, without needing to be specified, that the two transverse walls 118A and 118B on the one hand and the first lateral wing 116 on the other hand are arranged on either side of the first side wall 111 .

[0062] Advantageously, the angle between the first side wall 111 and the first lateral wing 116 is less than 90°, advantageously less than 80°.

[0063] Further advantageously, the first lateral wing 116 has one or more bent tabs 125 protruding toward the rear face 102 and terminating at a tip, thereby enabling the first lateral wing 116 to scratch the panel when it supports the panel.

[0064] Advantageously, as shown in Fig. 3, the first side wall 111 may also comprise at least one guide fin 124 (e.g., two guide fins) formed by a bent section of the first side wall 111. The at least one guide fin 124 is arranged to guide the clamping element about, in particular, when the clamping element is inserted into the passageway via the rear face 102. More particularly, the at least one guide fin 124 is directed towards the rear face 102 and bent in a direction opposite the first inner face 112.

[0065] 5 is a diagram of a second embodiment of a one-piece retaining piece 100 according to the present invention. In this second example, the retaining piece 100 essentially features all the features described with respect to the first example. However, according to this second example, the retaining piece 100 does not include a wedge 128.

[0066] According to this second example, the main portion includes a second side wall 211. The second wall 211 has a second inner surface 212 and a second outer surface 213, and a second upper edge 214A parallel to the elongation axis A and facing the rear surface 102.

[0067] The retaining piece 100 according to this second example also comprises a second lateral wing 216 which projects relative to the second outer surface 213 and causes the second wall 211 to extend from its second upper edge 214A.

[0068] More specifically, the holding piece 100 according to this second example is arranged such that the first wall 111 and the first lateral wing 116 are symmetrical to the second side wall 211 and the second wing 216 with respect to a central plane of symmetry relative to the first inner surface 112 and the second inner surface 212, respectively. Advantageously, the first wall 111 and the second wall 211 are parallel to each other.

[0069] More preferably, the transverse walls 118A and 118B extend between the first inner surface 111 and the second inner surface 212.

[0070] The retaining part 100 may also include beams 127 and 127M that provide a fixed mechanical link between the first wall 111 and the second wall 211 (FIG. 6).

[0071] Beams 127 and 127M are disposed on the rear surface 102 of the main portion 110. More specifically, beams 127 and 127M connect the first lower edge 114B to the second lower edge 214B of the second wall and opposite the second upper edge 214A.

[0072] Advantageously, one of the beams 127, called mounting beam 127M, is positioned midway between the two transverse walls 118A and 118B.

[0073] 7 shows a third embodiment of the one-piece holding piece 100 according to the invention. In this third example, the holding piece 100 essentially features all the features of the first and / or second embodiment of the holding piece according to the invention. According to this third example, the holding piece 100 is essentially flat in shape and comprises a holding bottom 129 extending perpendicularly to the first wall 111 and from the first inner surface 112. More specifically, the holding bottom 129 comprises a through opening 129b and is arranged midway between the two transverse walls 118A and 118B.

[0074] It is understood that the retaining bottom 129 is considered in this third example instead of the retaining beam 127M. In this regard, when the second main wall 211 according to the terminology of the second example is considered, the retaining bottom 129 mechanically connects the second wall 211 with the first wall 111. More specifically, according to this last embodiment, the retaining bottom 129 connects the first inner surface 112 with the second inner surface 212.

[0075] Additionally, the retention bottom 129 may be at a distance from the first top edge 114A and from the second top edge 214A.

[0076] In a particularly advantageous manner, the holding piece 100 according to this third example can comprise a catch means configured to catch a screw or bolt inserted in the opening in the direction from the front face 101 towards the rear face 102. In this respect, the catch means can in particular comprise two tabs, respectively called the first tab 130 and the second tab 230, which each extend in the direction from the rear face 102 towards the front face 101 and project relative to the holding bottom 129. More specifically, the first tab 130 and the second tab 230 are diametrically opposed to the opening 129b. Furthermore, the free ends of the first tab 130 and the tab 230, respectively called the first end 130a and the second end 230a, are curved inwards so as to be able to catch a screw or bolt inserted in the opening in the direction from the front face 101 towards the rear face 102.

[0077] Advantageously, the first and second tabs are obtained by cutting the first and second walls, respectively, in other words the first and second tabs are flush with the first and second walls, respectively.

[0078] Whatever the example considered, the holding piece 100 can be formed by stamping a metal sheet, in particular a sheet made of hardened steel, for example of the C67S type.

[0079] The invention also relates to an integral clamping element 300 intended to cooperate with the holding part 100 .

[0080] In this regard, figures 8 and 9 show respectively a clamping element 300 according to a first and second embodiment of the invention.

[0081] Whatever the example considered, the clamping element 300 comprises two uprights 310A and 310B mechanically fixed to each other, the uprights extending in two divergent directions in a plane P from first ends 312A, 312B respectively towards second ends 313A, 313B.

[0082] "Two divergent directions" means two directions carried by two non-parallel axes. More specifically, the two axes diverge from each other from a first end to a second end.

[0083] The clamping element 300 may comprise a beam 314 extending in a plane P and holding two uprights 310A and 310B fixed to one another.

[0084] The first ends 312A and 312B are arranged to allow the clamping element 300 to be attached to a rail, more specifically to a rail having a U-shaped cross section. More specifically, the first ends 312A and 312B are arranged to allow the clamping element 300 to be attached to the rail by snap-fastening. In this respect, the first ends 312A and 312B comprise first fastening means formed by first lateral abutments 315A and 315B.

[0085] The second ends 313A and 313B are provided with second fastening means intended to cooperate with the retaining edges 119A, 119B. In particular, the second fastening means are arranged to support the retaining edges 119A, 119B. In this respect, the second fastening means may comprise second lateral abutments 311A, 311B.

[0086] More specifically, the first lateral abutments 315A, 315B and the second lateral abutments 311A, 311B of the same uprights 310A, 310B face each other.

[0087] Each upright may be provided with a mounting abutment 316A, 316B at its second end. In particular, the two mounting abutments 316A and 316B extend inside the clamping element and thus converge.

[0088] As shown in FIG. 9, according to a second embodiment, the clamping element 300 comprises two outwardly bent or curved attachment hooks 317A, 317B.

[0089] The clamping element 300 according to the second embodiment can be provided with pre-attachment means which allow the clamping element 300 to be fixed to the rail without clamping, in order to allow the panel to be pre-positioned on the rail.

[0090] The pre-attachment means may in particular comprise pre-attachment abutments 318A, 318B arranged to enable the clamping element 300 to be snapped into the rail. In this respect, the pre-attachment abutments 318A, 318B of a given upright are arranged between the first lateral abutments 315A, 315B and the mounting hooks of that upright. Furthermore, the pre-attachment abutments 318A, 318B of a given upright have the same orientation as the first lateral abutments of that upright.

[0091] The invention also relates to a mounting kit comprising the holding part 100 and the clamping element 300 .

[0092] The present invention also relates to a panel mounting system comprising at least one mounting kit and at least one rail.

[0093] FIG. 10 shows the mounting of panels, in particular solar panels, on rails 500 according to the so-called top configuration.

[0094] The rail 500 has a U-shaped cross section. In this respect, the rail 500 comprises a bottom 501 on which rests side walls 502A, 502b, the edges of which, called attachment edges 503A, 503b, are bent or rolled up inwards so as to allow snap-fastening of the clamping element 300 by its first fastening means (first lateral abutments 315A, 315B).

[0095] The assembly therefore in particular involves snapping the clamping element 300 by its first fastening means at the mounting edges 503A and 503B of the rail 500. More specifically, the clamping element 300 is placed with one face, called the contact face, adjacent to a panel (not shown) resting on the rail. In particular, the clamping element 300 is placed against the contour of the panel.

[0096] Assembly also includes positioning the retaining piece 100 according to the first example. During this installation, the first lateral wing 116 is placed directly over the working surface of the panel opposite the contact surface. Additionally, during this installation, the second end of the clamping element 300 is inserted into the passage opening through the rear surface 102 of the retaining piece 100.

[0097] An assembly tool 500 is then mounted to support and position the second fastening means (second lateral abutments 311A, 311B) on one and the other of the retaining edges 119A and 119B. The assembly tool 500 may comprise a lever terminating at one of its ends in a hook, adapted to apply a force on one and the other of the mounting abutments 316A and 127M by supporting the mounting beam 316B. If the retaining edges 119A, 119B comprise contact tips 126, the contact tips may pierce the passivating oxide layer on the surface of the clamping element, thus allowing a better electrical contact.

[0098] The electrical contact between the rail and the clamping element can be improved by forming a protruding rim 319 on the first lateral abutment (FIG. 11). The protruding rim 319 is particularly likely to be crushed against the rail when the clamping element is snapped onto the rail, thus making it possible to establish a better electrical contact between the rail and the clamping element.

[0099] As soon as the clamping element 300 is snapped onto the rail 400 and the second fastening means supports the retaining edges, the clamping element 300 is under tension, which in turn exerts a force on the retaining edges 119A and 119B. This force clamps the panel between the first lateral wing 116 and the rail 400.

[0100] More specifically, the first lateral wing, which supports the working surface of the panel, holds the panel in support of the rail 400. The consideration of the bent tab 125 makes it possible to scratch the frame of the panel and thus to establish a better electrical contact between the holding part and the panel.

[0101] The improved electrical contact provided by bent tab 125, contact tip 126 and protruding rim 319 can be advantageously used to ground the panel.

[0102] Such an arrangement provides a clamp that is less sensitive to temperature changes and therefore more durable than clamps applied by screws or bolts.

[0103] Furthermore, the extent of the first lateral wing allows for a better distribution of the retention force over the working surface of the panel.

[0104] Finally, the proposed configuration makes it possible to take into account rails of reasonable width.

[0105] The assembly shown in FIG. 10 can also implement a holding part according to the second example, such that the part holds a first panel by its first wing and a second panel adjacent to the first panel by its second wing.

[0106] This assembly method is particularly suitable for fastening panels, in particular for fastening solar panels to a roof.

[0107] Figure 12 shows the mounting of a panel, in particular a solar panel, on a rail 600 according to the so-called bottom configuration. The assembly shown in figure 12 implements a clamping element according to a second embodiment.

[0108] The rail 600 is notably equipped with snap-fastening means that allow the insertion of the clamping element 300 by snap-fastening. In particular, the assembly comprises positioning the clamping element 300 in the rail 600 in a position called the pre-mounting position. In particular, the clamping element 300 is snapped onto the rail 600 by means of its mounting abutments 316A and 316B.

[0109] The retaining piece 100 is also placed in position. During this installation, the first lateral wing 116 is placed directly above the working surface of the panel 700 opposite the contact surface. Furthermore, during this installation, the second end of the clamping element 300 is inserted into the passage opening through the rear surface 102 of the retaining piece 100. In particular, this positioning is performed so as to position the second fastening means (second lateral abutments 311A, 311B) in support of one and the other of the retaining edges 119A and 119B.

[0110] The assembly tool 800 is then mounted so as to snap the clamping element onto the rail 600 by means of the first fastening means (first lateral abutments 315A, 315B).

[0111] The assembly tool 800 may comprise a lever, one of the ends of which is arranged to cooperate with one and the other of the mounting hooks 317A, 317B. In particular, the assembly tool 800 is adapted to apply a force to one and the other of the mounting hooks 317A, 317B.

[0112] As soon as the clamping element 300 is snapped onto the rail 500 and the second fastening means supports the retaining edges, the clamping element 300 is under tension, which in turn exerts a force on the retaining edges 119A and 119B. This force clamps the panel between the first lateral wing 116 and the rail 500.

[0113] More specifically, the first lateral wing, which supports the working surface of the panel, holds the panel clamped against the rail 500 .

[0114] The assembly shown in FIG. 12 may also implement contact tips 126, protruding rims 319, and bent tabs 125 similar to the assembly of FIG.

[0115] The assembly shown in FIG. 12 implements a retention part according to a second example, whereby the part retains a first panel by its first lateral wing and retains a second panel adjacent to the first panel by its second wing.

[0116] However, holding parts according to the first example or the third example may also be envisaged.

[0117] Alternatively, if a holding part according to the third example is considered, it is possible to consider the holding part to the rail by means of screws or bolts and fastening elements.

[0118] In this regard, figure 13 is a diagram of the cooperation between the holding part 100, the bolt 700 and the fixing element 800 for holding a photovoltaic panel on a rail 900. In particular, the bolt 700 cooperates by being inserted in the opening 129b and screwing with the fixing element 800. The fixing element is held in part in a groove, called the main groove, of the rail, so that the bolt forming the tie rod is under tension and therefore exerts a supporting force on a first lateral wing of the holding part 100 against the frame of the adjacent photovoltaic panel.

[0119] 14, the fixing element 800 may comprise an essentially flat main plate 801 and two lateral wings 802 and 803 that extend laterally of the main plate 801 by two opposing sides, called flanks. In particular, the two lateral wings 802 and 803 each extend in a divergent manner towards their contact ends 802A and 803A.

[0120] Finally, the fixing element also comprises two retention elements that directly connect the two lateral wings 802 and 803 and are configured to oppose an opening force that may be applied to the two lateral wings 802 and 803. In this regard, the retention elements may comprise two tabs, respectively called the first tab 804 and the second tab 805, which extend from the lateral wings 802 and 803, respectively, towards each other and perpendicular to the sides. In particular, the first tab 804 and the second tab 805 comprise stop means arranged at one and the other free end of the tabs, which stop means are arranged to oppose the separation of the two lateral wings 802 and 803 when an opening force is applied to the lateral wings 802 and 803. More particularly, the stop means comprise a hook 805A and a window 804. The hook 805A is arranged at the free end of the tab 805 and the window 804A is arranged at the free end of the tab 804. The hook 805A is engaged in a window which advantageously has a rectangular shape.

[0121] The invention also relates to a method for mounting photovoltaic panels on a rail, in particular comprising placing a first panel on the rail and fixing the panel to the rail by means of a clamping element and a holding part, more particularly a first lateral wing of the holding part used to hold the first panel on the rail supports a peripheral frame of the first panel by means of the clamping element.

[0122] The method includes placing a second photovoltaic panel adjacent to a first photovoltaic panel. More specifically, the second panel is first diagonally engaged by one side of the peripheral frame under a second lateral wing of a holding piece supported by its first lateral wing relative to the peripheral frame of the first panel. Secondly, the second photovoltaic panel is folded parallel to the first photovoltaic panel so as to be clamped against the rail by the holding piece considered.

[0123] Naturally, the invention is not limited to the described embodiments, and variants can be added thereto without departing from the scope of the invention as defined by the claims.
