DETAILED DESCRIPTION

The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

In the description and in the claims, the expressions “upper,” “lower” and their derivatives will be used without limitation respectively with reference to the upper portion and lower portion of FIG. 1.

In addition, in order to clarify the description and the claims, the terms longitudinal, vertical and transverse will be adopted without limitation with reference to the trihedron L, V, T indicated in the figures, the vertical axis V herein being considered to be parallel to the slope of the roof, without any reference to the terrestrial gravity.

In all these figures, identical or similar reference numerals represent identical or similar members or sets of members.

It is to be noted that in the present patent application, the terms “upstream” and “downstream” should be understood with reference to the slope of the roof on which the plate is intended to be mounted and to the flow direction of the runoff water.

In FIG. 1, there is represented a support plate 10 adapted to fit in a photovoltaic panel (not represented) and enable fastening and integration of this panel on a building roof.

The plate 10 includes a tight vertical overlapping arrangement 12 and tight lateral fitting arrangement 14.

In one form, the vertical overlapping arrangement 12 are formed by a transverse upper strip 16 and by a transverse lower strip 18 which are adapted to enable overlapping of an upper support plate and of a lower support plate vertically juxtaposed.

According to this configuration, the lower strip 18 of the upper plate 10 covers the upper strip 16 of the lower plate 10 so as to ensure a perfect tightness.

For this purpose, the overlapping arrangement are provided with a graduation 20 which is designed so as to adjust the vertical overlap and the coverage between two juxtaposed plates.

To this end, the graduation represents for example a graduated measuring scale, which is engraved, printed or molded on the upper strip 16 of the support plate 10.

Thus, the graduation 20 allows measuring the overlap of two support plates 10 and providing a low coverage and a good tightness.

In addition, the graduation 20 allows setting the overlap of two juxtaposed support plates 10 based on the dimension of the photovoltaic panel to be installed, so that the support plates can adapt to different formats of photovoltaic panels.

As can be seen in FIG. 3, the lateral fitting arrangement 14 comprise a first profile 22 and a second profile 24, each extending vertically on the sides of the plate 10 and each presenting a hollow section generally formed in an inverted U shape.

The first profile 22 presents a shape adapted to fit in the recess formed by the second profile 24, when two adjacent support plates 10 are juxtaposed transversely, so as to ensure a good tightness between the plates.

According to FIG. 4, a clip 26 is fastened on the profiles 22, 24 by means of a screw 28.

The clip 26 includes a first retaining leg 30 which is adapted to cooperate with a photovoltaic panel carried by a first plate 10, and a second retaining leg 32 which is adapted to cooperate with a photovoltaic panel carried by a second plate 10.

In the case of a pressure exerted on the photovoltaic panels, for example a pressure due to the wind, the panels can transmit a compressive effort with a vertical component on the fitting arrangement 14.

In order to inhibit crushing of the fitting arrangement 14, the support plate 10 is equipped with a reinforcement 34 which is interposed between the lateral fitting arrangement 14 and the roof.

A crushing of the fitting arrangement 14 is to be avoided because it would risk opening a passage for water infiltration, for example by deformation of the hole intended for the passage of the screw 28, or by a rise of the second profile 24.

The reinforcement 34 is an affixed part which is arranged in the recess delimited by the first profile 22 of the fitting arrangement 14 so as to resist crushing of the fitting arrangement 14.

In a non-limiting manner, the reinforcement 34 may also be integrated and formed by the first profile 22, for example during the molding of the first profile 22.

According to another aspect, with reference to FIGS. 1 and 2, the support plate 10 includes pads 36 for supporting the photovoltaic panel which are lifted so as to raise the photovoltaic panel.

The support pads 36 allow the positioning, the guidance, the wedging of the photovoltaic panel and the support of the feet of the mounters of the panels.

In addition, each support pad 36 is associated to a drilling area 38 which is arranged downstream of the support pads 36 in order to be protected from the water flow and which is raised so as to avoid the penetration of water.

By drilling area 38, is meant an area which is designed so as to enable the drilling and the passage of fastening device. The drilling area 38 may include an imprint or a mark indicating a drilling location, and/or an area mechanically pre-weakened in order to facilitate drilling, for example.

As can be seen in FIG. 2, each drilling area 38 is raised lesser than the associated support pad 36 so as to enable the arrangement of fastening device, such as screws (not represented), without these fastening device surpassing the associated support pad 36 in order not to hinder the set-up of the photovoltaic panel.

Besides, the support plate 10 delimits an empty space 40 intended for the passage of cables and for access to the framework of the roof.

The empty space 40 is surmounted by a bead 42 which is disposed so as to avoid the flow of the water coming from the ridge of the roof in the empty space 40.

A groove 44 is formed in the bead 42, allowing the passage of cables between the plate 10 and the photovoltaic panel.

As can be seen in FIG. 1, the plate 10 comprises a plurality of guide rails 46 which are arranged upstream of the empty space 40 along the flow direction of the water coming from the ridge of the roof, and which are generally arranged in an inverted V shape so as to divert the flow of the water on the lateral sides of the empty space 40.

Each guide rail 46 forms a lifted bead for diverting the flow of the water on the lateral sides of the empty space 40.

Besides, the plate 10 comprises means 50 for lifting the photovoltaic panel which allow ventilating the photovoltaic panel.

Finally, the plate 10 is equipped with wedges 52 which are arranged upstream of the support pads 36, and which allow flushing the water coming from the ridge of the roof.

In addition, the wedges 52 are designed so as to support the photovoltaic panel.

The plate 10 is formed in one single piece, with the possible exception of the reinforcement 34, in one form by injection molding, or by stamping or by any other manufacturing method.

The description of the disclosure is merely exemplary in nature and, thus, variations that do not depart from the substance of the disclosure are intended to be within the scope of the disclosure. For example, It will be understood that the plate 10 may also be designed and sized so as to enable mounting in a landscape fashion. Such variations are not to be regarded as a departure from the spirit and scope of the disclosure.
