• Roof arrangement for a terrace canopy kit of parts for building the roof arrangement. and terrace canopy comprising the roof arrangement
• the present invention relates to a roof arrangement for a terrace canopy.
• the pre sent invention also relates to a kit of parts for building the roof arrangement and a terrace canopy comprising the roof arrangement.
• Terrace canopies are usually arranged to screen off or, on the contrary, to clear an outdoor area.
• Such terrace canopies are often arranged near houses, restau rants, shops, etc. to screen off an outdoor terrace or the like from sunlight, precipitation and/or wind, or on the contrary, to temporarily allow in sunlight.
• These terrace canopies can be implemented, for example, in the form of an awning, a pergola, a veranda, a car- port, a pavilion, etc.
• Such a terrace canopy typically comprises a roof arrangement that is at least par tially supported by columns. Exceptionally, the roof arrangement may also be supported by another roof construction.
• the roof arrangement is generally constructed of several beams that are composed into one or more frames into which a roof infill can be attached. The beams themselves are often a composition of a plurality of individual profiles.
• Such a roof arrangement is typically supported by four (or more) columns between which a wall infill may be provided. Likewise, less columns may be used in case the roof arrangement is supported by other structures, such as a wall of an already existing structure.
• a roof arrangement for terrace canopies there are typically four orientations (namely above, below, outside and inside) for the frame of the roof arrange ment.
• “above” refers to the portion of the roof arrangement that is or will be oriented towards the top surface (i.e. the sky, e.g. the open air), "below” to the part of the roof arrangement that is or will be oriented towards the base surface (i.e. the ground, e.g. the terrace floor), “outside” to the portion of the roof arrangement that is or will be oriented away from the roof (i.e. away from the roof infill) and “inside” to the portion of the roof arrangement that is or will be oriented towards the inside of the roof (i.e. facing the roof infill).
• a known roof infill is formed by a roll-in and roll-out screen.
• this has a risk of water pockets and cannot handle a snow load.
• a relatively large slope is required for water drainage (i.e. at least 8°).
• the screen also gets dirty easily.
• the roof infill according to the present invention is of the type formed by a plurality of mutually parallel panels positioned on the inside of the frame and slidable between a distributed position and a stacked position.
• the panels are typically (partly) made of metal, such as aluminium, (laminated) glass or plastic, such as polycarbonate (PC) or polymethyl methacrylate (PMMA).
• GR 1006387 B discloses a roof arrangement with an inclined positioned frame in which 3 panels are mounted, the top panel (i.e. the nearest panel to the upper transverse beam) of which is fixed and the two bottom panels are slidable.
• the panels have an up wardly directed L-shaped reinforcing rib on their one transverse side and a downwardly directed L-shaped reinforcing rib on their other transverse side, that together increase the strength of the panels and prevent bending.
• Each rib has one and the same height such that the sum of two corresponding ribs is constant.
• the upper reinforcing ribs are provided with openings to allow drainage of precipitation due to the slope of the roof arrangement.
• a drawback of this known roof arrangement is the stacking height of the panels. This is namely the sum of the thickness of all panels together and in addition the height of the upper reinforcing rib (present on the upper platform) and the lower reinforcing rib (present on the lower platform). Based on the figures of the known roof arrangement, this amounts to a stack height of 8-10 times the thickness of one panel and this for only 3 panels. Furthermore, a lot of dirt (such as leaves and/or branches) can remain on the roof arrangement. This is because dirt will typically not flow through the openings in the ribs and will thus remain on a panel whereby it will be visible from the bottom side of the roof arrangement, which is not desirable.
• a drawback of this known roof arrangement is the stacking and sliding out of the panels. This requires a complex system with a spring system to lift the panels sufficiently such that they can slide out. This leads to an extremely thick roof frame in which all panels are stacked and the spring system is incorporated.
• a roof arrangement comprising a frame and a panel ar rangement attached to the frame, which frame comprises a transverse direction, a longi tudinal direction, a top side, a bottom side and at least one transverse beam extending in the transverse direction.
• the panel arrangement comprises: N panels slidable in the lon gitudinal direction between a distributed position and a stacked position, wherein N is a natural number larger than one, wherein a 1 st panel of said N panels is, in the distributed position, nearest at said transverse beam in the longitudinal direction, and wherein an N th panel of said N panels is, in the distributed position, furthest away from said transverse beam in the longitudinal direction, wherein each panel has a frame having a nearest beam and a farthest beam which are mutually substantially parallel and extend in the transverse direction, which nearest beam of a frame is nearer to said transverse beam than the far thest beam of said frame; and (N-l) pairs of reinforcing ribs each comprising an upper and a lower reinforcing rib, wherein an i th panel of the N panels is provided at its farthest beam with the one reinforcing rib of a pair of reinforcing ribs of said (N-l) pairs of reinforc
• the reinforcing ribs contribute to the strength of the individual panels. In particular, they prevent bending of the panels in the transverse direction or at least limit the bending.
• all upper ends of the upper reinforcing ribs are located in one and the same plane and the same applies for the lower ends of the lower reinforcing ribs. In this way, both the top side and the bottom side of the panel arrangement are neatly finished without a noticeable difference in height between the ribs.
• the bottom side of the frame is in the first plane and/or the top side of the frame is in the second plane.
• the panels do not protrude from the bottom side and/or the top side of the frame of the roof arrangement in the distributed position and the roof arrangement thus has a taut and uniform appearance.
• the panels slide between their stacked position and their distributed position via a substantially horizontal translation movement.
• the bottom sides of all lower reinforcing ribs are in the first plane and the top sides of all upper reinforcing ribs are in the second plane for each position of the panels during the horizontal translation movement.
• a horizontal translation movement is easy to perform such that also the design of the necessary guides for the panels can be simple without the need for complex stacking and/or sliding mechanisms.
• the panels never protrude relative to the roof frame in any position, such that the roof arrangement has a taut and uniform appearance in every panel position.
• the panel arrangement further com prises a guide system for guiding the panels between their stacked position and their dis tributed position, which guide system preferably is provided with tracks with each panel in a corresponding track, wherein more preferably the tracks are substantially parallel to the first plane.

• the inte gration of the guide system in the frame results in a compact roof arrangement.
• the panels are guided in a track on both longitudinal sides, which improves the sta bility and operation.
• the roof arrange ment further comprises a gutter for collecting precipitation discharged from the panels, which gutter is integrated in the first beam below the guide system.
• the gutter contrib utes to the drainage of water from the panel arrangement to the frame and can thus be hidden from view.
• the upper and lower reinforcing ribs of each pair of reinforcing ribs have substantially the same rigidity. This means that the farthest beam of frame i and the nearest beam of frame (i+1) have the same rigidity. Firstly, this ensures that the beams look visually similar in the sense that these beams have the same bending. In addition, this also ensures that the beams can hook into each other correctly.
• the lower reinforcing ribs of adjacent panels are provided with mutually cooperating engagement elements which, in the stacked position of the panels, engage each other to mutually align the bottom sides of the lower reinforcing ribs and/or the upper reinforcing ribs of adjacent panels provided with mutually cooperating engaging elements which, in the stacked position of the panels, engage one another for mutually aligning the top sides of the upper reinforcing ribs.
• the engaging elements are formed by a notch on one reinforcing rib and a bulge on another reinforcing rib. A rib and bulge are easy to manufacture during an extrusion process, which is typically the manufacturing method of the reinforcing ribs, such that additional production steps are avoided.

• Such an embodiment has an increased number of possible configurations with re gard to light transmission and/or watertightness and combines in particular the ad vantages of a panel arrangement and a screen arrangement. Specifically, the following configurations are possible:
• Both the panel arrangement and the screen arrangement are open, such that the roof arrangement is maximally open. A large incidence of light is possible and there is also sufficient ventilation.
• the panel arrangement is closed and the screen arrangement is open.
• the roof design is watertight and determines in itself the light transmission. In the case of a glass panel arrangement, there is sufficient incidence of light since the screen arrangement is still open.
• the panel arrangement is open and the screen arrangement is closed.
• the screen arrangement then serves as sun protection, while there is still sufficient ventilation in view of the open position of the panel arrangement.
• Both the panel arrangement and the screen arrangement are closed, such that the roof arrangement is both watertight and sun-resistant.
• the roof arrangement also allows for further positions in which the panel arrangement and/or the screen arrangement are located between their open and closed positions. This again increases the options to obtain the desired light transmission and/or watertightness.

• the screen 16 can also be moved to any position between its open and closed position as shown in Figure 4A where the screen 16 is not completely rolled-in such that the panels 15 are not visible in their stacked position. Due to the use of the frame for mounting both the panel arrangement 13 and the screen arrangement 12, the roof arrangement is relatively compact, in particular the arrangement has a limited height, since both arrangements 11, 12 are integrated together in a single roof arrange ment 10.
• the panel arrangement 13 shown in Figures 2 to 4B does not form part of the in vention and is only intended to describe cooperation with an underlying screen arrange ment 14.
• the panel arrangement of the present invention will be described with reference to Figures 5A to 14B. It should be understood that the panel arrangement 13 may be re placed by that of Figures 5A to 14B and that the advantages of an underlying screen ar rangement 14 thus also apply to a panel arrangement according to the present invention.
• Figures 5A and 5B show a first embodiment of a roof arrangement 10 with a panel arrangement 21.
• the panel arrangement 21 comprises three panels 22i , 22 2, 22 3 which are slidable between a stacked position ( Figure 5A) and a distributed position (Figure 5B) be tween two transverse beams Hi, ll 2 via a horizontal translation movement.
• Each panel 22 has a flat frame 23 with a nearest beam 23a and a farthest beam 23b.
• the terms “near” and “far” are relative to the transverse beam Hi against which panel 22i is fixedly at tached.
• the frames 23 of adjacent panels 22 are located in different horizontal planes.
• the panel arrangement 21 further comprises two pairs of reinforcing ribs each com prising an upper reinforcing rib 24 and a lower reinforcing rib 25. More specifically, the first panel 22i has a far lower reinforcing rib 24i , the second panel 22 2 has a near upper reinforcing rib 25i and a far lower reinforcing rib 24 2, and the third panel 22 3 has a far upper reinforcing rib 25 2 .
• Each pair of reinforcing ribs 24, 25 together has the same height d, although the mutual relationship between the length of the lower reinforcing ribs 24 and the upper reinforcing rib 25 varies between pairs.
• the bottom sides of the lower reinforcing ribs 24 are located in one and the same horizontal plane a, in which also the bottom side of the frame (i.e. the beams 11, 12) is located.
• the top sides of the upper reinforcing ribs 25 are located in one and the same horizontal plane b in which also the top sides of the frame (i.e. the beams 11, 12) are located, and this for every possible position of the panels 22.
• the stacking height of the panels 22 is thus limited to the height of the frame, which is advantageous, and the bottom side of the roof arrangement 10 is tautly finished in one and the same plane a.
• the reinforcing ribs 24, 25 of one pair have the same rigidity such that hooking is easier.
• the hooking of two adjacent panels 22 is best shown in Figure 11.
• the upper frame 23, is provided on its farthest beam on the bottom side with a first gripping means 26 and the lower panel 23j +i is provided on its near beam on the top side with a corresponding second engaging means 27.
• the engaging means 26, 27 are formed by pro files with a corresponding hook shape. It is therefore advantageous that these profiles have substantially one and the same bending in order to simplify the engagement.
• Such engagement means 26, 27 result in a substantially watertight closure of the panels 22 in their distributed position.
• the third panel 223 is also provided with a farthest reinforcing rib 28. This contributes to preventing the bending of this panel. But this is not essential as this could also be accommodated by providing the necessary support on the transverse beam II2 .
• This is also done at the first panel 22i where a nearest reinforcing rib 31 is provided.
• the transverse beam lli at the first panel 22i is also provided with a finish 29 (or a support) which preferably has the same appear ance as a reinforcing rib 25. This also applies to the transverse beam II2 where on the top a finish 30 is provided.
• FIG. 12A and 12B A variation is shown in Figures 12A and 12B where the reinforcing ribs 24, 25 are provided with mutually cooperating engagement members 32, 33 which, in the stacked position of the panels 22, engage one another to mutually align the bottom sides of the lower reinforcing ribs 24, and for mutually aligning the top sides of the upper reinforcing ribs 25.
• the engaging elements are formed by a notch (e.g. a slot) 32 on one reinforcing rib and a bulge 33 on another reinforcing rib.
• each panel 22 in Figures 5A and 5B are generally Z-shaped.
• each panel 22 has a flat frame 23 with a lower reinforcing rib 24 on the far transverse side and an upper reinforcing rib 25 on the near transverse side.
• the reverse is also pos sible (i.e. a lower reinforcing rib 24 on the near transverse side and an upper reinforcing rib 25 on the far transverse side) as schematically shown in Figures 8A and 8B.
• Such panels 22 are maximally stackable in a limited height with a minimal ground surface because there are no sides where two lower or upper reinforcing ribs rest against each other.
• Figure 10A illustrates the guide for a panel arrangement of Figure 5 or Figure 8.
• one rail 34 is provided in the longitudinal beams 12, in which a longitudinal side of a panel 22 is guided. Since there are two longitudinal beams 12 in the terrace canopy, preferably, there is also a corresponding rail (not shown) in the other longitudinal beam. The two rails 34 then together form a track along which a panel 22 is guided. In this way, there are thus as many (or 1 less) tracks than there are panels 22.
• FIGS 13A and 13B show a variation of the embodiment shown in Figures 5A and 5B.
• the lower reinforcing ribs 24 are formed by a rigid portion 24a and a modular portion 24b located below the rigid portion 24a.
• the rigid portion 24a mainly determines the strength of the lower reinforcing rib 24. It is also possible to apply the same to the upper reinforcing ribs 25.
• the modular portion can be used for the integration of different modules to increase the functionality of the roof arrangement 10. Examples of possible modules and/or functionality are a different finish (e.g. a wood structure), lighting (e.g. LED lighting), a heating module, a ventilation module, an audio module, a communication module (e.g. WiFi or Bluetooth), a sensor module ( e.g. a rain sensor, a wind sensor and/or a light sensor), a power generation module (e.g. a solar cell).

• FIG. 6A and 6B A first example is shown in Figures 6A and 6B with two U-shaped panels 22i , 22 2 on the first transverse beam Hi and two U-shaped panels 22i , 22 2 on the second transverse beam II2 . Each set of panels also has 1 pair of reinforcing ribs 24, 25. A pair of reinforcing ribs 35, 36 is also provided for the connection between the two sec ond panels.
• the panels 22 can be guided in two tracks 34 (see Figure 10B).
• Figures 7A and 7B A similar ar rangement is shown in Figures 7A and 7B where there are a total of 6 U-shaped panels guided in two tracks 34 (see Figure 10B).
• U-shaped panels are that fewer different panels 22 have to be man ufactured compared to Z-shaped panels since there are fewer different reinforcing ribs.
• the stacking surface is larger or the number of panels (and therefore the size) is limited.
• a further advantage is that the height difference between the frame of the 1 st panel and the last panel is independent of the number of panels, while with Z- shaped panels this only increases as the number of panels increases.
• FIG. 9A A combination of U-shaped and Z-shaped panels is also possible as shown in Fig ures 9A and 9B.
• a schematic view of the tracks 34 for this embodiment is shown in Fig ure IOC.
• each panel 22 comprises reinforcing ribs 24, 25 which are not limited to only one side of the frame 23. This is especially advantageous if the panel infill placed in the frame 23 is convex. Such panel infill is advantageous in terms of water drainage, as already described. Flowever, the disadvantage of a convex panel infill is that it can protrude from the top side of the frame 23 or that a relatively high frame 23 is to be provided, as a result of which material and/or production costs can increase. Because the reinforcing ribs 24, 25 are located on either side of the frame 23, a vertical space is created between the frames 23 of adjacent panels 22 in the stacked position of the panels 22 (see Figure 14A).
• the convex panel infill may be located at least partially in this vertical space.
• the crucial aspect that returns in each of the panel arrangements 21 according to the present invention as described above is that adjacent panels together have one pair of reinforcing ribs 24, 25 which together have a uniform height and that the frames 23 of adjacent panels are located in a different horizontal plane. This allows to limit the stack height and to use a simple horizontal translation movement to move the panels 22, keep ing the panels 22 at all times within the lower and upper limits of the frame of the roof arrangement 10.
• the panel arrangement 21 according to the present invention as described above is therefore also particularly advantageous for cooperation with a screen arrangement (as in Figures 2-4) because the bottom side of the panel arrangement 21 is located in a hori zontal plane a, such that a screen 16 can be placed just below this plane a.
• a screen arrangement as in Figures 2-4
