SUPPORTING DEVICE FOR SOLAR PANEL

The invention relates to a support device for a solar panel on a roof.

The installation and fixing of a solar panel, whether a photovoltaic panel or a thermal solar panel, is traditionally carried out using a support device with hooks and metal rails.

This type of hook device according to the prior art generally comprises a plurality of hooks which each have a U shape formed by a lower section, an upper section and an intermediate fitting portion.

The lower section extends in the direction of the slope of the roof and is arranged under a tile, or a slate, the lower section being fixed on a roof element, such as a rafter, for example by screwing.

The upper section of each hook extends above the tile and supports a fixing bar for the solar panel, the system comprising at least two fixing bars which are provided for fixing the panel to the roof.

The tiles that form the roof covering partially overlap to seal the roof.

We see that under the weight of the snow on the solar panel or under the weight of a person, the hook presses on the tile which is arranged directly below the tile which covers the upper section of the hook.

Thus, the lower section of the hook risks damaging the tile on which the hook rests, in particular because of the weight of the solar panel supported by the hook.

In addition, the installation of the hook may require cutting a part of a tile or may cause the lifting of a tile, which may affect the waterproofing of the roof and cause water infiltration under the roofing.

The present invention aims in particular to resolve these drawbacks and to do this relates to a support device for a solar panel on a roof, characterized in that it comprises:

- a support leg which comprises a lower base adapted to be fixed on a frame, and an upper support section which extends axially along a main axis, from a lower part connected to the base, to a delimited upper part by an upper face,

- a roofing element which delimits a chimney for the passage of the support section, the chimney forming an annular flange which extends around the support section, and

- A connecting device for solar panel which comprises a lower part mounted on the support section of the support leg and an upper connecting part which is adapted to support a solar panel.

The device according to the invention makes it possible to support a solar panel on a roof while limiting the risks of damage to the roof elements.

In addition, the device according to the invention integrates perfectly with a roof.

Also, the flange of the roof element prevents water from flowing through the chimney to seal the device and the roof.

According to another characteristic, the support device comprises a cover forming a bell which covers the support foot (12) and the chimney formed by the roofing element and which delimits a passage hole along the main axis for the passage of the connecting device.

The hood helps to seal the support device by preventing water from entering through the chimney.

According to another characteristic, the roofing element is produced by thermoforming molding of a plastic plate.

Thermoforming makes it possible to copy a wide variety of shape of roof elements to adapt to an existing roof.

According to another characteristic, the roof element has the shape of a tile.

According to another characteristic, the connection device comprises:

- a threaded fixing rod which extends axially along the main axis, from a lower section screwed onto the support section of the support leg, up to an upper section, and

- a support bracket which is mounted on the upper section of the threaded rod and which is suitable for supporting a mounting bar for a solar panel.

According to another characteristic, the support device comprises a mounting bar which extends perpendicular to the main axis and which is mounted on the support bracket, the mounting bar being adapted to support a solar panel.

According to another characteristic, the mounting bar is a metal profile which delimits at least one groove suitable for receiving a mounting flange of a solar panel.

According to another characteristic, the connection device comprises a nut which is screwed onto the threaded rod and which is in axial support on the upper face of the support leg to block the threaded rod in rotation on the support leg, the stirrup support being in axial support on the nut.

The invention also relates to a support system for a solar panel, of the type comprising a plurality of support devices of the type described above and at least two mounting bars which are each fixed on at least two support devices.

There is shown in Figure 1 a support device 10 for solar panel (not shown) on the roof.

As can be seen in FIG. 2, the support device 10 essentially comprises a support foot 12, a roofing element 14, a connection device 16 for a solar panel and a cover 18.

The support leg 12 comprises a lower base 20 which extends parallel to the plane of the roof and which is fixed to a structural element 22 by screws (not shown) for example.

The structural element 22 is here a chevron. However, the structural element 22 may be a support strip for a roofing element or an added piece, such as a board, which is fixed to the framework.

Also, the support leg 12 has an upper support section 24 of generally cylindrical shape, which extends axially along a vertical main axis A, from a lower part 26 connected on the base 20, to an upper part 28 which is delimited vertically by an upper face 30.

The support section 24 comprises a threaded fixing sleeve 32 which extends axially along the main axis A and which opens into the upper face 30 through an inlet hole 34.

According to the example described, the roof element 14 has the shape of a corrugated tile.

However, the roof element 14 may also have a flat shape, such as a slate.

The roof element 14 defines a chimney 36 for the passage of the support section 24 of the support leg 12.

The chimney 36 forms a cylindrical annular flange 38 which extends around the support section 24 of the support foot 12, along the main axis A, from an upper face 40 of the roofing element 14.

As can be seen in FIG. 2, the collar 38 projects vertically from the upper face 40 of the roofing element 14, so that the collar 38 forms a sealing barrier which prevents water from flowing through the chimney 36 of the roof element 14.

According to an exemplary embodiment of the preferred invention, the roofing element 14 is produced by thermoforming molding of a plastic plate, for example polypropylene.

However, the roofing element 14 can also be produced by any other manufacturing process, the roofing element 14 can in particular be produced in the manner of a commercial tile, by molding in terracotta or in synthetic material.

The connection device 16 comprises a lower part 42 mounted on the support section 24 of the support leg 12 and an upper connection part 44 which is adapted to support a solar panel.

More particularly, the connecting device 16 comprises a threaded rod 46 for fixing at the end of which is mounted a bracket 48 for support.

The threaded rod 46 extends axially along the main axis A, from a lower section 50 which is screwed into the socket 32 provided for this purpose, up to an upper section 54 on which the support stirrup 48 is mounted.

By way of non-limiting example, an additional socket can be arranged at the bottom of the support section 24 of the support foot 12, for example on the base 20, to promote the mechanical strength of the threaded rod 46.

In order to block the threaded rod 46 in rotation on the support foot 12, the connecting device 16 comprises a nut 56, forming a lock nut, which is screwed on the threaded rod 46 and which is in axial support on the upper face 30 the support leg 12.

The bracket 48 includes a base 58 of generally cylindrical shape which is screwed on the free end of the threaded rod 46 and which is in axial support on the nut 56.

In addition, the bracket 48 has an upper part 60 of square tubular section, visible in FIG. 1, which is integral with the base 58 and which delimits a housing adapted to accommodate a mounting bar 62 for solar panel.

The mounting bar 62 extends transversely, perpendicular to the main axis A and perpendicular to the slope of the roof, the mounting bar 62 being adapted to support a solar panel.

To this end, the mounting bar 62 is a metal profile which defines an upper groove 64 and a lower groove 66 which are each adapted to receive fixing flanges (not shown).

Thus, a solar panel can be fixed to the bar 62 by flanges which cooperate with the upper groove 64 of the bar 62.

However, the mounting bar 62 is optional, the solar panel being able to be fixed directly to the threaded rod 46 or to the bracket 48 of the support device 10 according to the invention.

According to another aspect, the cover 18 forms a bell which caps the chimney 38 formed by the roofing element 14 and which delimits a hole 68 for passage along the main axis A, for the passage of the base 58 of the bracket 48 of the connecting device.

The cover 18 makes it possible in particular to prevent infiltration of rain inside the support device 10.

As can be seen in Figures 2 and 3, the support section 24 of the support leg 12 forms a plurality of annular notches 69 which extend around the main axis A from an external face of the support section 24 and which are provided to cooperate with the internal face of the cover 18 to retain the cover 18 on the support leg 12.

The invention also relates to a support system 70 for solar panel, illustrated in FIG. 4, which comprises a plurality of support devices 10 of the type described above and two mounting bars 62 (of which only one is shown in FIG. 4) which are each fixed on two support devices 10.

FIG. 5 shows an alternative embodiment of the support device 10 according to the invention, which is similar to the embodiment described above and which has a simplified design.

According to this alternative embodiment, the support section 24 of the support leg 12 is a metal tube which delimits a tapped hole 32 which extends along the axis A and the base 20 of the support leg 12 is a metal plate welded to the support section 24.

Still according to the variant embodiment, the connecting device 16 comprises a threaded rod 46 which extends axially along the axis A and which is screwed into the tapped hole 32.

The tapped hole 32 shown in FIG. 5 is machined directly in the support leg 12.

However, without limitation, the support section 24 can be a hollow tube, the lower section of the threaded rod 46 being screwed onto a first lower nut which is welded to the base 20, at the bottom of the support section 24, and a second upper nut is screwed onto the threaded rod in the vicinity of the upper free end of the support section 24, the second nut being able to bear on the internal wall of the support section 24 to promote the mechanical strength of the threaded rod 46.

Also, in order to block the threaded rod 46 in rotation on the support leg 12, the connecting device 16 comprises a nut 56, forming a counter nut, which is screwed on the threaded rod 46 and which is in axial support on the upper face. 30 of the support leg 12.

With reference to FIG. 5, the upper section 54 of the threaded rod 46 projects axially from the cover 18, the upper section 54 of the threaded rod 46 passing through a mounting bar 62.

Finally, the free end of the threaded rod 46 is locked on the bar 62 by a nut 72 which is arranged in an upper groove 64 of the bar 62.

The present description of the invention is given by way of nonlimiting example.
