TECHNICAL FIELD

The invention relates to the field of roof panels. In particular, the invention provides a roof panel which may be configured as roof filling in a roof system. The invention also relates to a roof device comprising a plurality of said roof panels, which are suitable in particular as a roof device for a terrace covering. The invention also relates to a roof construction comprising said roof device. The invention also relates to the use of said roof panel in a roof device. The invention furthermore also relates to a method for assembling said roof panel.

TECHNOLOGICAL BACKGROUND OF THE INVENTION

A terrace covering is a structure typically consisting of posts and beams and is freestanding or mounted against a fagade. A roof is then placed on the beams. This may be a fixed roof, but nowadays there is an increasing demand for opening roofs, that is to say roofs which can repeatedly switch between a closed and an open position of the roof.

The roof filling of an openable roof may consist, for example, of a roll-up canvas, lamellae which rotate around their axis, or slidable segments. The segments are typically panels which are made from (laminated) glass or plastic, such as PC or PMMA. Depending on the choice of material, the translucency and robustness of the roof may be matched to the desired application.

However, existing roof fillings typically suffer from the following problems:

- a roll-up canvas at an incline suffers from a risk of water pockets forming and is unable to deal with heavy loads of snow. A large angle of inclination is required for the water to run off (+- min 8°). In addition, there are only limited options with regard to the filling and there is no flexibility with regard to changing the aesthetics of the filling. Moreover, the canvas becomes soiled easily.

- Pivotable and sliding lamellae are not translucent (with regard to glass lamellae, which are translucent, a covering can only accommodate a limited number thereof). In addition, there are only limited options with regard to the filling and there is no flexibility with regard to changing the aesthetics of the filling. Typically, the underside gives a clinical impression.

- a sliding panel roof typically suffers from problems related to the incline and curvature and is usually not translucent. In addition, there is usually only 1 limited option with regard to the filling and there is no flexibility with regard to changing of the aesthetics of the filling. Typically, the underside gives a clinical impression.

- a sliding panel roof with canvasses is not water-tight and unable to withstand snow loads. There is a risk of puddles forming and of the canvas becoming soiled.

- a sliding glass roof has a visible incline and is not heat-absorbing. In addition, there is usually only 1 limited option with regard to the filling and there is no flexibility with regard to changing of the aesthetics of the filling.

- a fixed roof of taut canvas is no movable roof filling and is not translucent.

A general shortcoming of existing roof fillings is a limited (splash) watertightness and water drainage. Good water drainage is difficult to achieve, in particular for roofs where water cannot flow away in a natural manner. Standing water can exert pressure on the roof surface with the risk of damage, local sagging or leaking. A similar problem may occur during snowfall, during which the roof may be subjected to heavy loads for long periods followed by a local collection of melting snow water.

Finally, the existing roof fillings do not allow further finishing of the underside as desired by the user, or only to a very limited degree. As a result thereof, the undersides typically give a clinical, unpleasant or impersonal impression. There is therefore a need for a roof filling which offers a solution to one or more of the abovementioned problems.

SUMMARY

It is an object of the present invention and the preferred embodiments thereof to offer a solution to one or more of the abovementioned drawbacks of flat roofs.

The invention also relates to a roof device comprising a plurality of said roof panels. The invention also relates to a roof construction comprising said roof device. The invention also relates to the use of said roof panel in a roof device. The invention furthermore relates to a method of assembling said roof panel. The roof panel according to the present invention can improve the (splash) watertightness and/or water drainage, strength and/or resistance to (snow) loads, finishing options, translucency and/or solar control. The roof panel according to the present invention can also prevent the formation of water pockets.

Unless defined otherwise, all terms disclosed in the invention, including technical and scientific terms, have the meaning which a person skilled in the art usually gives them. For further guidance, definitions are included to further explain terms which are used in the description of the invention.

An aspect of the invention relates to a panel for a roof device comprising a panel frame and at least two panel fillings attached to both sides of the panel frame; arranged in such a way that a first, upper panel filling forms a water-tight protection above a second, lower panel filling. A further aspect of the invention relates to a roof device comprising a roof frame and at least one, preferably a plurality of, said roof panels arranged in the roof frame (as roof filling). A further aspect of the invention relates to a roof construction comprising a support structure on which, to which or in which said roof device can be fitted.

A roof panel - or, as used herein, panel - is a rigid structure which can form part or be a segment of a roof filling in a roof frame. A panel will typically have a beam-shaped or block-shaped structure, consisting of six virtually rectangular surfaces; namely a top surface, a bottom surface (or base), and four sides. The periphery of the bottom surface is preferably virtually the same size as the periphery of the top surface. The term virtually should be interpreted as meaning that the aforementioned body or structure comes significantly close to the aforementioned size or geometric shape; that is to say apart from some roundings, curves, projections, connecting elements, grooves, slots, ridges, openings, connecting pieces, reinforcing means and the like; reference is made to the figures for further clarification. Every reference to a surface or side of a panel will be interpreted in relation to the position of the panel after fitting in the roof frame of the roof device: the underside is the side which is or will be directed towards the base of the roof device (the ground, e.g. the terrace floor), while the upper panel wall or top wall is the panel wall which is or will be directed towards the top surface of the roof device (the sky, e.g. the open air).

There may be countless variations in the dimensions of the panels. The dimensions may be adapted, inter alia, to the size of the roof device, the number of panels, the material from which the panels are made, etc. By way of example, a panel may have a length of at least 0.50 m to at most 5.00 m; such as 2.00 m, 2.50 m, 3.00 m, 3.50 m, 4.00 m, 4.50 m, etc. By way of example, a panel may have a width of at least 0.50 m to at most 3.00 m; such as 1.00 m, 1.50 m, 2.00 m, 2.50 m, etc. By way of example, a panel may have a height of at least 1 cm to at most 50 cm; such as 5 cm, 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, etc. The person skilled in the art is expected to have sufficient knowledge to be able to adapt the dimensions of the roof panel to the desired embodiment.

The panel frame - or, as used herein, frame - refers to a rigid structure which is suitable for supporting, and preferably framing, the at least two panel fillings. The frame comprises at least one frame profile. A frame profile - or, as used herein, profile - refers to a rigid and preferably elongate body, typically used as a border of a frame. Depending on the desired embodiment, a profile may be rounded or flat, may have a wide or narrow wall, may be hollow or filled with filling material on the inside, may be ridged or smooth, and/or may comprise decorative finishes. The desired dimensions of the frame and, by extension, those of the profiles will typically correspond to the desired dimensions of the panel. The person skilled in the art is expected to have sufficient knowledge to be able to adapt the panel frame to the desired embodiment. The profiles are typically made of a rigid material. This may be, for example, aluminium. Aluminium has many advantages as a material for profiles, as it is strong while also being light, readily able to withstand adverse weather conditions and requiring little maintenance. However, other materials are also suitable and the person skilled in the art is expected to know their advantages and drawbacks. Depending on the material, a profile may be produced by means of different techniques, including extrusion, milling, folding, casting, welding, etc. The person skilled in the art is expected to know the suitable manufacturing technique.

Typically, the frame has a virtually quadrangular, preferably rectangular, shape. The frame may be formed by a single frame profile which is bent several times. However, it is easier and more efficient to produce several frame profiles and to then couple these together in order to form the frame. The panel frame will typically comprise four profiles; in particular two main profiles which are typically arranged at the front side and rear side of the roof panel and consequently form the front wall and rear wall, and two side profiles which are typically arranged at the end side of the roof panel and consequently form the side walls. The front side and rear side of the roof panel will typically be formed by the long sides of the roof panel and the end side by the short sides. The person skilled in the art will understand that, depending on the desired embodiment of the roof panel, this may also be reversed, in particular that the front side and rear side of the roof panel will be formed by the long sides of the roof panel and the end side by the short sides. The main profiles and side profiles will be discussed in more detail below.

During fitting in the roof panel, the first panel filling will typically be the upper panel filling; that is to say that the first panel filling forms the top side of the roof panel and, if fitted in a roof device, also the top side of the roof. The first panel filling will ensure the water-tight protection of the roof. The first panel filling is made from a water-tight material which is preferably fitted orfittable in the panel frame at an incline and/orwith a specific convex curvature in a water-tight manner. As a result thereof, the water which lands on the roof panel will be able to run off via the sides of the roof frame, without landing on the second panel filling, which could possibly lead to markings, damage or permanent marks. In addition, the first panel filling can be structurally reinforced in order to be better able to carry loads, such as snow, with limited and/or non-permanent sagging. As a result thereof, no load is applied to the second panel filling, thus preventing deformation, such as pocket formation.

The first panel filling will typically be a plate which fills the space of the panel frame; preferably the entire space between the main profiles of the panel frame. The first panel filling may be made of different materials or even combinations of materials. The choice of material may be tailored, inter alia, to the size of the roof (rigidity), the use of the roof device (translucent or opaque), the climate in which the structure is fitted (mainly sunny, rainy or snowy), etc.. By way of example, the first panel filling may be made of metal (e.g. aluminium), plastic (e.g. PC, PMMA, PVC), (laminated) glass, etc., and/or combinations of different types of materials. Optionally, the first panel filling may be coated, for example with a water-repellent coating. The person skilled in the art is expected to know the advantages and drawbacks of the different types of material and coatings.

The first panel filling may be opaque, translucent or optically transparent. The term opaque is understood to mean that the panel filling blocks visible light virtually completely; for example allows at most 5% of the visible light to permeate; preferably at most 3%; more preferably at most 1%. The term translucent is understood to mean that the panel filling partially allows visible light to permeate, but also partially blocks and/or diffuses it; for example allows at least 10% of the visible light to permeate or diffuses for example at least 90% of the visible light; for example allows at most 90% of the visible light to permeate or diffuses for example at least 10% of the visible light. The term optically transparent is understood to mean that the panel filling allows visible light to permeate virtually completely; for example allows at least 90% of the visible light to permeate or diffuses at most 10% of the visible light; preferably allows at least 95% of the visible light to permeate or diffuses at most 5% of the visible light; more preferably allows at least 98% of the visible light to permeate or diffuses at most 2% of the visible light; even more preferably allows at least 99% of the visible light to permeate or diffuses at most 1% of the visible light.

A surface of the first panel filling may be curved. Preferably, the surface of the first panel filling will be convex. As used in this document, convex means that the surface is curved towards the exterior. The convex surface will typically form the top side of the roof panel. The convex shape has the advantage that the rainwater and/or snow water will run off in the direction of the side profiles of the panel for improved water drainage. The convex surface may be arcuate. As used in this document, arcuate means that the surface of the first panel filling is curved to the exterior, as is the case with the circumference of a circle. The convex surface may be circular or spherical. As used in this document, spherical means that the surface of the first panel filling is curved to the exterior, as is the case with the circumference of a sphere. An arcuate or spherical surface will result in improved water drainage. The curve of the convex surface may optionally deviate partly or completely; for example in order to form an elliptical or oval surface.

The radius of curvature (R) of the curved surface is at least 10 m to at most 150 m. The radius of curvature is preferably 50 m to 130 m; more preferably 60 m to 120 m; more preferably 80 m to 100 m; more preferably 85 m to 95 m; for example 85 m; for example 86 m; for example 87 m; for example 88 m; for example 89 m; for example 90 m; for example 91 m; for example 92 m; for example 93 m; for example 94 m; for example 95 m. The person skilled in the art will understand that the radius of curvature is calculated as a radius of curvature interval on the basis of the R test, wherein the length corresponds to the chord of the curved panel filling and the height is measured from the highest (centre) point to the chord. Optionally, the top may be supported or reinforced internally.

The top of the curved panel filling may be at least 10 mm to at most 50 mm higher than an end of the first panel filling on the end sides of the roof panel. The top is preferably at least 10 mm to at most 45 mm higher; more preferably 10 mm to 40 mm; more preferably 15 mm to 35 mm; more preferably 20 mm to 30 mm; for example 25 mm.

A surface of the first panel filling may be inclined. The incline has the advantage that the rainwater and/or snow water will run off in the direction of the side profiles of the panel for improved water drainage. Preferably, the surface of the first panel filling will form a saddle roof. As used in this document, the term "saddle roof" means that the first panel filling consists of at least two inclined panel filling components which are placed against each other which intersect in a ridge. The components are preferably coupled to each other in the ridge in order to achieve a stable construction. The inclined panel filling components are preferably of equal length; in other words the first panel filling forms a symmetrical saddle roof. Alternatively, a single panel filling may form a saddle roof by being bent in at least one point; the bending point will form the ridge. Optionally, the top of the ridge may be supported or reinforced internally. The saddle roof shape has the advantage that the rainwater and/or snow water will run off in the direction of the side profiles of the panel for improved water drainage.

The incline of the first panel filling may have an inclination of at least 0.5° to at most 5.0° from the ridge to one end of the first panel filling at the end sides of the roof panel. The inclination is preferably at least 1.0° to at most 3.0°; more preferably 1.0° to 2.5°; more preferably 1.0° to 2.0°; more preferably approximately 1.5°; for example 1.3°.

The ridge of the curved panel filling may be at least 10 mm to at most 50 mm higher than one end of the first panel filling at the end sides of the roof panel. The top is preferably at least 10 mm to at most 45 mm higher; more preferably 10 mm to 40 mm; more preferably 15 mm to 35 mm; more preferably 20 mm to 30 mm; for example 25 mm.

The first panel filling is preferably attached to the panel frame by the frame profiles clamping the body of the first panel filling. In this case, the frame may form a space which is suitable for accommodating the first panel filling. Preferably, the first panel filling will be clamped along at least a top side and an underside. An edge, preferably all edges, of a top surface and/or bottom surface of the first panel filling may be partly, preferably entirely, covered by the frame profiles. Alternatively or additionally, the first panel filling can be clamped along the sides. Preferably, the sides of the first panel filling will be covered entirely by the frame profiles.

Clamping of the first panel filling may be achieved by providing the main profiles and/or side profiles with a U-shaped profile (also referred to as a C-shaped profile), wherein the distance between the upright walls of the U-shaped profile (also known as the height) virtually corresponds to the thickness of the panel filling. By sliding the first panel filling between the upright walls, it will remain clamped after adjacent profiles have been coupled thereto.

Clamping of the first panel filling may be achieved by providing the main profiles and/or side profiles with two clamping profiles, wherein a first clamping profile will make contact with a top side of the first panel filling and a second clamping profile will make contact with a bottom side of the first panel filling. The clamping profiles may then be coupled to an upright side wall of the main profiles and/or side profiles in order to clamp the first panel filling.

The first panel filling may be attached to the panel frame by means of a leakproof sealing. Preferably, when securely clamping the panel filling, the sealing will close all clear spaces and thus prevent potential leaks of rainwater and snow water. The sealing can also be fitted between the frame and the first panel filling. The sealing can also be fitted between individual frame profiles. The sealing is typically made of a compressible material. This may be, for example, plastic or rubber. Alternatively, the sealing may be produced by means of curable materials, such as silicones.

The panel frame may furthermore comprise a drainage groove for downward drainage of rainwater or snow water which preferably runs off laterally from the top side of a first panel filling. A drainage groove may be formed by making the length of the first panel filling less long than the corresponding length of the main profiles of the panel frame to which the first panel filling will be attached. This results in an elongate opening during assembling between a side of the first panel filling and a side profile of the panel frame from which the water can run off. On the side of the first panel filling, a downwardly pointed dripping nose profile may be attached which protects the second panel filling situated below it against the water which is running off in a downward direction. In a preferred embodiment, both lateral profiles will form a drainage groove on both sides of the roof panel, with a dripping nose profile preferably being attached to both sides of the first panel filling.

Optionally, it is possible, when mounting the roof panel in a roof device, to fit the drainage groove above a roof frame gutter of the roof device or roof construction to improve water drainage and to prevent leaks on the base of the roof device, such as the terrace. By keeping the width of the drainage groove smaller than the gutter width of the roof frame gutter, the water sealing can be hidden from view.

The panel frame may furthermore comprise a roof panel gutter for laterally draining off rainwater or snow water which preferably runs off laterally from the top side of a main profile. A roof panel gutter can be formed by providing a main profile with an inclined structure atone end of the main profile. Asa result thereof, a roof panel gutter is created between two adjoining roof panels during fitting of the roof panels in a roof device, in particular between two adjoining main profiles of two adjoining roof panels, that is to say between a front main profile of a first roof panel and a rear main profile of a second roof panel. The water which runs off laterally can then run off via the above-described dripping nose in a downward direction, preferably along the above-described drainage groove, ora separate drainage opening may be provided on the side of the main profile. The second panel filling will typically be the lower panel filling when fitting the roof panel; that is to say that, during fitting in a roof device, the second panel filling forms the underside of the roof panel and also the underside of the roof. The second panel filling will form the finish of the roof. The second panel filling is typically at least attached to the panel frame at two points of attachment, so that the second panel filling may be just below the underside of the roof panel. The second panel filling may be partly attached to the panel frame or in an entirely continuous manner. Since the second panel filling does not have a water-draining function, it does not have to be fitted at an incline and may therefore also be fitted completely flat. This not only improves the visual appearance, but also offers the possibility of using (non-waterproof or non-coated) materials which were previously deemed unsuitable for use in finishing the bottom side of roof panels. In addition, it is also possible to use materials with sun-screening and/or reflective properties which were previously deemed unsuitable due to limited soil- proofness or waterproofness. The second panel filling also offers the possibility of incorporating all kinds of decorations or embellishments on or under the roof panel. The second panel filling may be made of different materials or even combinations of materials. The choice of material may be adapted to the use of the roof device and the desired finish. The second panel filling may be a flexible or a rigid panel filling or a combination of both. Some preferred embodiments are described in more detail below. It will be clear that the second panel filling is not limited to one of the described embodiments and alternative embodiments or combinations of embodiments also exist. The second panel filling may be sun-screening or have a sun-screening surface. The term sun-screening is understood to mean that the second panel filling partly allows the visible light to pass, but also partly blocks and/or diffuses it; for example allows at least 20% of the visible light to pass or, for example, diffuses at least 80% of the visible light; for example allows at most 80% of the visible light to pass or, for example, diffuses at least 20% of the visible light.

The second panel filling may be opaque or have an opaque surface. The term opaque is understood to mean that the second panel filling almost completely blocks out the visible light; for example blocks out at least 90% of the visible light; for example blocks out at least 95% of the visible light; for example blocks out at least 99% of the visible light.

The second panel filling may be reflective or have a reflective surface. The term reflective is understood to mean that the second panel filling partly or completely reflects the visible light; for example reflects at least 50% of the visible light; for example reflects at least 75% of the visible light; for example reflects at least 99% of the visible light.

The second panel filling may comprise a canvas. Here, a canvas refers to a flexible medium which has been pretensioned, referred to in this document as pretensioned canvas, or is tensionable, referred to in this document as tensionable canvas. Examples of suitable types of canvas material for the present invention are coarse or woven fabric or a plastic film, such as polyester, glass fibre, (fine) metal gauze or other types of canvas material. The canvas may be a sun-screening or reflective canvas. The canvas may consist of several layers, for example in order to achieve better sun-screening or reflective properties. The canvas may be tensionable or pretensioned. The canvas may be rollable. The canvas may optionally be provided with a print or decoration.

The second panel filling may comprise lamellae. Here, lamellae refer to a plurality of relatively thin and/or narrow pieces of material which are arranged parallel to each other. Examples of suitable types of lamellae material for the present invention are wood, plastic, metal, etc. Optionally, the lamellae may be rotated and/or arranged at a certain angle. It will be clear that such embodiments in which the canvas is, for example, rollable, the lamellae are rotatable or can be arranged at a certain angle, but also in which such second panel fillings can be switched on or off, are removable, detachable, etc., make it possible to determine the sun-screening and/or reflective properties of the second panel filling and more particularly, determine them individually, that is to say per roof panel.

The second panel filling may comprise a perforated screen. In this case, the term screen refers to a covering structure having a plurality of small openings. An example of a suitable screen for the present invention is a perforated plate, produced by creating patterns in a metal or wooden plate. An example of a suitable screen for the present invention is expanded metal, produced by stretching out slits provided in a metal plate to form diamond-shaped meshes.

The second panel filling may comprise a lattice or grate. Here, a lattice refers to a frame of bars which have been fitted on top of each other and which are parallel to each other or intersect. Examples of suitable lattice material for the present invention are wood, plastic, metal, fabric, etc. The lattice material may be provided in the form of a rope, string, band and the like; for example a fabric string. Optionally, the lamellae may be covered with flowers or plants, such as climbing plants.

The second panel filling may be movably or slidably arranged in or on the panel frame. The movable arrangement of the second panel filling may make it possible to move the second panel filling (temporarily) out of view. This may make it possible to adjust the incidence of light of the roof device, for example when the first panel filling is transparent or translucent and the second panel filling is sun-screening or opaque. This may furthermore also facilitate maintenance or cleaning of a bottom side of the first panel filling due to improved access. A roll-up canvas which can be unrolled or rolled up by means of a winding mechanism is an example of a movable panel filling. Sliding lamellae which can be pushed onto or against each other by means of a sliding mechanism are an example of a movable panel filling.

Depending on the embodiment of the second panel filling, the way in which the second panel filling is attached to the panel frame will differ. Below, some preferred embodiments are described in more detail. It will be clear that the attachment of the second panel filling is not limited to one of the described embodiments and that the different techniques can, if desired, be combined.

In a flexible embodiment of the second panel filling, for example in the form of canvas, the second flexible panel filling will be attached to the panel frame along at least two sides, so that the panel filling can run along the underside in a tensioned way. Preferably, at least two sides are attached to the main profiles of the frame. Preferably, the second panel filling may be attached to the frame in a repeatable manner - it can be mounted and unmounted repeatedly. This may make it possible to replace the second panel filling in case of damage, wear or for decorative reasons.

The main profiles may comprise one or more points of attachment. A point of attachment is preferably partly or entirely incorporated in the frame profile in order to hide the attachment means from view. A point of attachment may be a projecting body which extends laterally on one side of a frame profile. The point of attachment may be a hook onto which the panel filling is hooked, for example at an opening in the panel filling which is provided for the purpose. The point of attachment may be a (click- fittable) coupling element to which the panel filling can be coupled, for example by effecting coupling with a complementary coupling element which is incorporated in the panel filling. The point of attachment may be a clamping element which can securely clamp the panel filling in one or more locations.

The second flexible panel filling may also be incorporated in the main profile along the entire edge. The main profile may, for example, comprise a clamping profile which will securely clamp an entire edge of the flexible panel filling. This may be achieved, for example, by providing a thickening on the edge of the flexible panel filling which can be clamped by the clamping profile, for example a canvas string or zip.

The frame may comprise a tensioning system in order to tension the second flexible panel filling if it is tensionable. Preferably, at least one main profile comprises a tensioning system; the second main profile can then anchor the flexible panel filling or, alternatively, tension the flexible panel filling in two directions by means of a second tensioning system. By way of example, the tensioning system may comprise a tensioning slat and bolt which are attached to one end of a main profile. By clamping the second flexible panel filling behind the tensioning slat, it is possible to apply tension to the panel filling by rotating the bolt. The bolt and associated tensioning slat may be incorporated in the frame profile to hide the tensioning system from view; tensioning may then be achieved, for example, by means of a ratchet spanner or Allan key. Optionally, one end of a main profile may serve as tensioning point, with the second flexible panel filling being curved and tensioned over the tensioning point. However, alternative tensioning systems are also possible, such as tensioning of the second flexible panel filling by means of a rope, chain, tensioning strap, springs and the like.

Just like the main profiles, the side profiles may also comprise one or more points of attachment for attaching the second flexible panel filling. Alternatively, the second flexible panel filling may be attached to a side profile along the entire edge. A thickening profile of the side profile may be pushed over a thickening on the edge of the flexible panel filling. The thickening profile is preferably a zip guide or string. The thickening profile may be removable in order to make simpler fitting possible; for example by attaching the flexible panel filling beforehand and subsequently coupling it to the side profile (in a click-fitted manner). The coupling will ensure that the flexible panel filling is put under tension. If, for example, the flexible panel filling expands due to an increase in temperature, it will always be kept under tension by the side profiles to which the panel filling is attached as these will also expand due to the increase in temperature.

In a specific embodiment in which the frame comprises a drainage groove as described above, a dripping nose profile may be attached along the edge of the flexible panel filling, preferably the entire edge of the flexible panel filling. The dripping nose profile will not only provide protection against drained-off water, but may also support and/or keep the second flexible panel filling under tension.

In a rigid embodiment of the second panel filling, for example as a hard screen or lattice, the second rigid panel filling will be attached to at least one, preferably a plurality of points of attachment. Attaching may be effected, inter alia, by means of attachment means, such as screws, bolts, nuts, nails and the like. The frame may comprise an attachment element for attaching the second panel filling to the frame, such as a hook, ring, (screw) eyelet, bracket and the like. Attachment may be permanent, for example by nailing or screwing the panel filling to the frame. Attachment may be non-permanent, for example by hooking the panel filling onto the frame or by hanging it therefrom. The second rigid panel filling may also be attached to the first panel filling, for example by providing points of attachment at the bottom surface of the first panel filling.

In a specific embodiment in which the frame comprises a drainage groove as described above, a dripping nose profile may be attached to the side of the rigid panel filling, preferably along the entire side of the rigid panel filling. The dripping nose profile will not only provide protection against downwardly drained-off water, but will also be able to support the second flexible panel filling.

The main profiles of the panels may comprise a reinforcing element which can support an adjoining panel. As a result thereof, the reinforcing element may improve the strength of an adjoining panel, resulting in a reduced risk of sagging due to water or snow loads. The reinforcing element may comprise an upwardly directed body which extends laterally from a main profile, preferably a top side of a main profile. The upwardly directed body may be at right angles to the top side of the roof panel or main profile, preferably by making a perpendicular angle with a tangent over the top surface of the roof panel (if the upper panel wall is curved). The reinforcing element may be an L-shaped angle profile which is attached to or forms part of a main profile.

If a plurality of roof panels comprising a reinforcing element are fitted next to each other in a roof device, a ribbed structure will be created on the top surface of the roof device. This ribbed structure may improve the strength and resistance of the entire roof device and consequently reduce or prevent the risk of giving way or sagging of the roof; for example due to snowfall or accumulation of branches and leaves.

A roof device or roof for short may comprise a roof frame in which at least one, preferably a plurality of roof panels, according to an embodiment as described herein, are or may be fitted. A plurality of panels indicates that two or more panels are present in the roof device. The roof is preferably a flat roof with a roof surface which is virtually level; that is to say having an incline of less than 10° and preferably less than 5°, for example less than 2° or 1°. The inclination is determined by the difference in height between adjoining panels; the individual panels may, for example, have a curved surface without any a difference in height with respect to each other.

The roof device may be a slidable roof or sliding roof; the term sliding is understood to mean that the roof can slide to an open and to a closed position in a repeatable manner. A sliding roof will typically comprise a sliding system which is configured to slide the panels along the length of the roof, such as a rail system. The panels may, for example, slide over the rail system in a direction which makes it possible to open and close the roof by sliding. A rail system will typically comprise one or more guide rails which are fitted or fittable to a side of the roof frame. The panels may comprise movement elements which are coupled to the rail system, such as a roller bearing which can roll or slide across the surface of a guide rail. A panel may also be attached in a non-slidable manner. Such a fixed panel may serve, for example, as a support, delimitation or as a coupling point. The person skilled in the art is expected to have sufficient knowledge of sliding systems for sliding roofs to be able to produce such an embodiment. Suitable or preferred embodiments of the roof device are also suitable or preferred embodiments of the sliding roof.

The roof device may furthermore comprise a roof frame gutter for lateral drainage of rainwater or snow water which preferably runs off laterally from the top side of a roof panel. The roof frame gutter may comprise an elongate beam-shaped or semi-circular construction which is typically connected to a vertical drainpipe. In this case, the roof frame gutter prevents the discharged water from flowing directly from the roof and hitting the terrace or ground situated below.

The roof frame gutter may be a separate structure which is attached or connected to a panel frame. Alternatively, the roof frame gutter may be incorporated in the panel frame. The roof frame gutter will be arranged to collect the water running off from a roof panel. The roof frame gutter may be arranged along the roof panel, with the roof frame gutter preferably adjoining one end of the roof panel. The roof frame gutter may be arranged under a roof panel, with the roof frame gutter preferably being arranged under one end of the overhead roof panel. The roof frame gutter may be arranged under a drainage groove of an overhead roof panel. The roof frame gutter may be attached under the overhead roof panel.

The roof frame gutter may be arranged under a dripping nose profile of an overhead roof panel. The roof frame gutter may comprise an upright wall to guide the water. The upright wall may have a raised top edge to prevent drained-off water from spilling over. The top edge may be raised to be higher than or at least at the same height as the bottom edge of a dripping nose profile of an overhead roof panel. This has the advantage that splashes of drained-off water are caught, preferably via the drainage groove. In addition, this will also prevent a gap from being created on the side of the roof device due to the presence of a drainage groove.

Alternatively, said roof panel may also serve as a filling for a wall arrangement; the roof panels will form functional wall panels. Use of the wall panels in a (vertical) wall may result in an improvement with regard to a wind-proof and/or water-tight wall filling with an improved finish on the inside; for example by the combination of a wind-proof and/or water-tight first panel filling on the outside and a desired type of material on the inside. This combination may make new kinds of wall arrangements possible, for example by providing a translucent and/or transparent first panel filling and a sun-screening and/or reflective second panel filling. The wall panels may also lead to an improvement in insulating properties, both in terms of improved heat retention and of improved cooling (by sun-screening). The wall arrangement may comprise a sliding system, as is the case with a sliding wall. It will be clear that the embodiments of one structure described below may also be applied to other, similar structures; that is to say that suitable or preferred embodiments of the roof device or sliding roof are also suitable of preferred embodiments of the wall arrangement or sliding wall and vice versa.

In a further aspect, the invention relates to a roof construction comprising a support structure on which, to which or in which a roof device according to one or more embodiments as described herein can be fitted. The support structure may comprise walls which are configured to form a, preferably rectangular, space in which the roof device can be fitted.

The support structure of the roof construction or the wall construction may comprise upright support elements, such as posts and beams to which the roof device can be fitted. The roof construction or the wall construction may be, for example, a terrace covering, pergola, carport, vault and the like.

In a further aspect, the invention relates to a method for assembling a roof panel according to one or more embodiments as described herein; the roof panel preferably comprising at least two main profiles and at least two side profiles, and optionally at least two dripping nose profiles; the method preferably comprising the following steps: (al) attaching a first panel filling to the at least two opposite two main profiles;

EXAMPLES

By way of example, reference is made to the figures. The embodiments illustrated in the figures and their reference numerals relate to preferred embodiments of the present invention and should by no means be interpreted as being limiting.

Example 1: Roof panel

Fig. 1A shows an illustration of a roof panel (100) viewed along a top side of the panel. The roof panel (100) comprises a panel frame comprising four profiles: two main profiles (110), in particular a front main profile (111) which is arranged at the front of the roof panel (100) and consequently forms the front wall and a rear main profile (112) which is arranged at the back of the roof panel (100) and consequently forms the rear wall, and two side profiles (120) which are arranged on the sides of the roof panel (100) and consequently form the side walls.

The roof panel (100) furthermore comprises a first panel filling (200) attached to the frame. The first panel filling (200) is entirely contained in the opening formed by the four profiles (110, 120). In this specific example, the first panel filling is securely clamped to a main profile (110) by a clamping profile (140); this clamping arrangement is explained in more detail in further figures. The rear main profile (112) furthermore comprises an upwardly directed reinforcing element (180) which extends laterally from the rear main profile (112).

Fig. IB shows an illustration of the same roof panel (100) viewed along a bottom side of the panel. The roof panel (100) comprises the same components as mentioned for Fig. 1A; only the second panel filling (300) is visible in Fig. IB. In this specific example, the first panel filling (200) forms the top side of the roof panel (100) and the second panel filling (300) forms the bottom side of the roof panel (100). Fig. 2 shows a cross section of a roof panel (100) viewed along a side of the panel. In this illustration, only the two main profiles (110) are visible.

The first panel filling (200) is clamped between the front main profile (111) and the rear main profile (112) by means of a plurality of clamping profiles (140), in particular an upper clamping profile (140a) and a lower clamping profile (140b). The clamping profiles (140) are coupled to the main profiles (110) in order to secure the first panel filling (200). The first panel filling (200) is attached to the panel frame by means of a leakproof sealing (210); the leakproof sealing comprises a plurality of sealings (210), which are inter alia fitted between the first panel filling (200) and the clamping profiles (140), and between the clamping profiles (140) and the main profiles (110). This ensures that the first panel filling (200) forms a water-tight cover.

In this specific example, the second panel filling (300) is a tensionable canvas (301) which is provided with a thickening (360) at a first and a second end of the canvas. The second panel filling (301) is attached to the front main profile (111) and the rear main profile (112) by arranging the thickening (360) in a point of attachment (150). The point of attachment (150) may, for example, securely clamp the thickening (360) by providing an opening which is smaller than the size of the thickening (360). By attaching the canvas (301) at at least two points of attachment (150), the second panel filling (301) will hang from the underside of the roof panel. The canvas (301) will preferably be attached in a continuous manner. The canvas (301) is tensioned by means of a tensioning system (170) which is incorporated in the front main profile (111). The tensioned second panel filling (300) will be protected against water which ends up on the top side of the roof panel (100) and possibly runs off over a top side of the first panel filling (200).

Fig. 2 furthermore shows the presence of a roof panel gutter (195) formed at an end of the front main profile (111) of the panel frame. The roof panel gutter (195) will provide lateral water drainage for water which ends up on the main profile.

Fig. 3 shows a specific embodiment of a roof panel (100) wherein the first panel filling (200) has a symmetrical saddle roof shape. The first panel filling (200) comprises two inclined panel filling components (200a, 200b) which are coupled to each other in the ridge (205). This embodiment will ensure that water which ends up on the top side of the first panel filling (200) will run off in the direction of the side of the roof panel (100).

Example 2: Drainage groove

In a preferred embodiment, the roof panel (100) may comprise a drainage groove (190). The drainage groove (190) is formed between the dripping nose profile (130) attached to one end of the first panel filling (200), the end side of the roof panel (100), and a side profile (120). This drainage groove (190) will provide downward water drainage for water which ends up on the roof panel (100). In order to protect the second panel filling (300) from water which runs off along the drainage groove (190) of the roof panel (100), a dripping nose profile (130) may be provided.

Fig. 4 shows a first embodiment of a dripping nose profile (130) comprising a downwardly pointed body along which the water can run off, a clamping space (240) for clamping the first panel filling (200) and a securing means for securing the second panel filling (300). In the first embodiment, the securing means is a thickening profile (160) which can be coupled in a click-fitted manner to the dripping nose profile (130). Upon coupling, the thickening profile (160) will be arranged under the clamping space (240) and thus also under an edge of the first panel filling (200). The dripping nose profile (130) comprises a point of attachment (150) in which a thickening - typically present on the edge the second panel filling (300) - can be clamped.

Fig. 5 shows a second embodiment of a dripping nose profile (130) comprising the same components as the above-described first embodiment; except that upon coupling of the thickening profile (160) to the dripping nose profile (130), the thickening profile (160) will be arranged next to the clamping space (240) and thus also next to an edge of the first panel filling (200). This second embodiment may make it possible to tension the second panel filling (300) more laterally.

Fig. 6 shows the first embodiment of the dripping nose profile (130) described in Fig. 4 after having been attached to the first panel filling (200) in the clamping space (240) provided and of the second panel filling (300) in the point of attachment (150) provided. Here, the second panel filling (300) is a tensionable canvas (301) with a clampable thickening (360) at one end. The further figures then show the placement of the dripping nose profile (130) after the first (200) and the second (300) panel fillings have been secured in a panel frame. The opening between, on the one hand, the dripping nose profile (130) and, on the other hand, a side profile (120) of the panel frame will form a drainage groove (190).

Fig. 7 shows a cross section of the roof panel (100) viewed from a front side of the roof panel (100). Fig. 8 shows a cross section of the roof panel (100) viewed from a top side of the roof panel (100). Fig. 9 shows a cross section of the roof panel (100) viewed from a second angle from the top side of the roof panel (100).

Fig. 10 shows a cross section of the roof panel (100) viewed along a rear main profile (110) and a side profile (130). This view also shows the device for attaching the first panel filling (200) to a main profile (110), as described in Example 1. In particular, Fig. 10 shows that the first panel filling (200) is clamped to a main profile (110) by an upper (140a) and a lower (140b) clamping profile. The ends of the first panel filling (200) are sealed in a leakproof manner by a plurality of sealings (210). The second panel filling (300) is attached to the same main profile (110) by clamping a thickening (360) in a point of attachment (150).

Fig. 11 shows a roof frame gutter (490) of the roof device (400). The roof frame gutter (490) is arranged under an overhead roof panel (100), in which case it is attached to a side of the roof frame (410). The opening of the roof frame gutter (490) is positioned under the drainage groove (190), formed between a side profile (120) and a dripping nose profile (130) of the roof panel (100), so that all of the water running off can be collected. In this case, the top edge of the upright side wall of the roof frame gutter (490) can catch the splashing water because the intermediate space between this top edge and the roof panel (100) is limited to the minimum.

Fig. 12 shows a roof device comprising 6 roof panels (2x3, stacked in 2 stacks, each of 3 panels in height), arranged so as to be movable along a side of the roof frame (410). In this way, a slidable roof is formed.
