Definitions

• the invention is in the field of roof devices for retractable roofs.
• the invention provides for a roof device comprising retractable roof panels.
• the invention also relates to a canopy comprising the roof device.
• a terrace canopy is a structure typically made up of columns and beams that can be mounted freestanding or on a facade.
• a roof is then attached to or on top of the beams.
• This may be a fixed roof, but in modern housing construction there is an increasing demand for retractable roofs, for example, retractable flat roofs; i.e. roofs whose surface area runs nearly horizontally, without an inclination.
• the roof infill of a retractable roof can, for example, consist of a rollable fabric or screen, slats that rotate around their axis and may also be retractable, or segments that can slide over one another.
• the segments may be panels that are partly made of (layered) glass or plastic, such as PC or PMMA. Depending on the choice of material, the light transmittance and robustness of the roof can be tailored to the desired application.
• An inclined Tollable fabric has a risk of formation of pockets of water and cannot handle snow loads.
• a relatively high angle of inclination is required for water drainage (+/- min 8°).
• Pivotable and/or retractable slats are not translucent (translucent glass slats are limited in the number of pieces possible in a canopy). Furthermore, only limited infill options exist and there is no flexibility to change the aesthetics of the infill. The underside feels characteristically chilly.
• a retractable panel roof typically contends with problems related to inclination and curvature. It is usually not translucent. Furthermore, there is usually only one limited infill option and there is no flexibility to change the aesthetics of the infill. The underside feels characteristically chilly.
• a retractable panel roof with fabrics is not waterproof and cannot withstand snow loads. There is a risk of pocket formation and soiling of the fabric.
• a retractable glass roof has a visible inclination and is not sunproof. Furthermore, there is usually only one limited infill option and there is no flexibility to change the aesthetics of the infill.
• a fixed canvas span roof is not a movable roof infill and is not translucent.
• the purpose of the present invention is to solve, or at least partly solve, one or more of the aforementioned disadvantages of flat roofs.
• the current invention concerns a roof device for a canopy.
• the roof device comprises a frame provided with a pair of first beams which are located opposite one another; a panel device fixed onto the frame, wherein the panel device comprises a plurality of stackable panels slidable between an open position and a closed position, wherein the panels form a substantially waterproof roof in their closed position; and a screen device fixed onto the frame, which device is located underneath the panel device, wherein the screen device comprises at least one screen movable between an open and a closed position, wherein the screen in its open position is substantially invisible, and wherein the screen in its closed position covers the panels substantially completely, wherein at least one, preferably both, of the first beams are provided with a rail system configured for the guidance of the panels between their open and closed positions; a screen guide system configured for the guidance of the screen between its open and closed positions; and at least one channel arranged for the collection of precipitation discharged from the panel device, which is located between the rail system and the screen.
• Such a roof device has an increased number of possible configurations in terms of light transmission and/or waterproofness and in particular combines the advantages of a panel device and a screen device. Specifically, the following configurations are possible:
• Both the panel device and the screen device are open such that the roof device is maximally open. There is a lot of light incidence and sufficient ventilation possible.
• the panel device is closed and the screen device is open.
• the roof device is waterproof and in itself determines the light transmittance. In the case of a glass panel device, there is sufficient light incidence as the screen device is still open.
• the panel device is open and the screen device is closed.
• the screen device then acts as a sunshade, while there is still sufficient ventilation given the open position of the panel device.
• Both the panel device and the screen device are closed such that the roof device is both waterproof and sunproof.
• the roof device may also allow further positions wherein the panel arrangement and/or the screen arrangement are situated between their open position and closed position. This again increases the options to obtain the desired light transmittance and/or waterproofness.
• both the rail system, the screen guide and the gutter are integrated into one of the first beams, resulting in a compact roof device.
• a water drain is provided on at least one side, preferably both sides of the panel device such that incident precipitation can be diverted to the frame without thereby impacting on the screen device, possibly causing damage, for example damp spots.
• the gutter has a bottom and a raised wall, wherein the top of the raised wall is situated above the screen in the closed position of the screen.
• the screen guide is preferably integrated into the bottom or raised wall of the gutter.
• a gutter formed by an L-shaped profile is easily applicable in a roof device for a canopy. The integration of the screen guide avoids the need to attach a separate element to the gutter using fastening means (e.g. bolts or screws), which fastening means can cause damage to the gutter (e.g. a perforation).
• the rail system comprises one or more tracks in a first of said first beams and one or more corresponding tracks in a second of said first beams, wherein each panel is guided on both sides in one of said one or more tracks and one of said one or more corresponding tracks.
• the panels are therefore guided on both sides in tracks incorporated in the first beams. This contributes to a compact design with a minimum of necessary components.
• the screen guide comprises a first screen guide in a first of said first beams and a corresponding second screen guide in a second of said first beams, wherein the screen is guided on both sides in the screen guide and the corresponding screen guide.
• the screen is thus guided on both sides in screen guides incorporated into the first beams.
• the roof device comprises a control system configured for the control, in particular, the mutual independent control of the panel device and the screen device.
• the control system can be a manual control system, wherein a user moves the panels and/or the screen directly or indirectly.
• the control system is preferably a motorised control system.
• a motorised control system will typically comprise a motor and control means that converts the movement of the motor into a movement of the panels and/or screen.
• the roof device comprises an nearly rectangular frame onto/into which the panel device and the screen device are attached.
• the use of the same frame for the mounting of both the panel device and the screen device simplifies the installation of the roof device and is, in particular, advantageous when using a common rail system as described above.
• the frame comprises, in addition to the first pair of beams, also a second pair of beams which together form nearly a rectangle, wherein the second beams are located opposite one another.
• the first pair of beams can be used to hold the rail system as described above and/or the second pair of beams can be provided with an enclosure for holding the screen in its open position and/or at least one panel of the plurality of panels can be fixed to one of the second pair of beams.
• the construction of the frame of the roof device from parallel beams essentially simplifies the structure of the roof device as different functions are performed by the beam pairs.
• the plurality of panels is divided into two sets of panels positioned relative to one another, which sets are preferably symmetrical relative to one another such that, in their closed position, they each form nearly half of the roof, and wherein said at least one screen is formed by two screens positioned relative to one another, which screens are preferably symmetrical relative to one another such that, in their closed position, they each cover nearly half of the roof.
• said at least one screen is formed by two or more screens, which screens are preferably located relative to one another at opposite ends of the roof device, wherein, more preferably, the screens are symmetrical relative to one another such that, in their closed position, they each cover nearly half of the roof.
• the advantage of using multiple screens is that the same surface area can be covered with smaller screens. There is, therefore, less tendency for the screens to sag and the space required for the screens in their open position is also smaller given that a screen roller with a smaller diameter can be used.
• the sliding direction of the panels is nearly identical to the sliding direction of the screen, in particular horizontal.
• the screen can be rolled-in and rolled-out wherein the open position is formed by the screen in its rolled-in position and the closed position is formed by the screen in its rolled-out position.
• the panels, in their closed position are aligned side by side in the same (horizontal) plane and the panels, in their open position, are stacked aligned one above another.
• the panels comprise a connection element and a connection point, wherein the connection element of each panel is configured for coupling and decoupling with a connection point of an adjoining panel.
• the panels comprise a panel frame and a panel infill which, preferably, is attached to the panel frame with a leak-proof seal.
• the panel infill is translucent and/or transparent.
• the screen is sunproof and/or reflective.
• the screen extends nearly horizontally in its closed position and/or the panels extend nearly horizontally in their closed position.

• the most closed position of the roof device (500) is shown in Figure 21 D wherein both the panel device (510) and the screen device (530) are completely closed. In this way, the roof device (500) is waterproof and not translucent.
• the panel device (510) can make use of a single-track or multi-track rail system and/or the described stacking systems and/or the connection systems and/or the described panels, optionally with the described drainage.
• the roof device (500) comprises a roof frame formed by pivot beams (502) and tension beams (504), commonly referred to as beams (502, 504), of which one each is shown in Figure 22.
• the panel device (510) comprises a plurality of panels (512), three in the embodiment shown, stacked one above another in their open position ( Figure 22A) and next to one another in a plane in their closed position ( Figure 22B).
• the lower panel (512) is firmly connected to the tension beam (504), which improves the waterproofness of the panel device (510).
• the pivot beam (502) has a rail system (not shown) as described above for guiding the panels (512).
• the panel device (510) is a screen device (530) comprising a screen (532), also referred to as a canvas.
• the screen (532) can be rolled in and out and, in its rolled-in position, is housed in a housing (534) that is firmly attached to the tension beams (504).
• the pivot beams (502) are also provided with a screen guide (536) which is also part of the screen device (530).
• the top of the screen guide (536) can also serve as a roof frame gutter (1490) to collect precipitation discharged from the panel device (510).
• the screen (532) can also be moved to any position between its open and closed position as shown in Figure 22A wherein the screen (532) is not fully rolled in such that the panels (512) are not visible in their closed position.
• the screen (532) is located entirely under the gutter (1490) and the screen guide (536) is incorporated in the bottom of the gutter (1490), but in other embodiments the screen (532) can also mainly be located next to the gutter (1490) in which case the screen guide (536) will be incorporated in the raised sidewall of the gutter (1490) as shown in Figure 23.
• the only condition to prevent the screen (532) from coming into contact with drained precipitation is that the screen (532) is not higher than the top edge of the gutter (1490).
• the beams (502, 504) are typically made up of one or more profiles as illustrated in Figure 23.
• the profiles are typically made of a rigid material. This can be aluminium, for example. Aluminium has many advantages as a profile material, as it is both robust and light, resistant to adverse weather conditions and requires little maintenance. However, other materials are also suitable and their advantages or disadvantages are assumed to be known to the person skilled in the art.
• a profile can be produced using various techniques depending on the material, including extrusion, milling, setting, casting, welding, etc., wherein extrusion is preferred. The appropriate production technique is assumed to be known to the person skilled in the art.
• the profiles are connected in a specific way.
• pin connections also known as click connections
• hook connections are used.
• a pin connection typically contains an elastic element (not shown) in a female element, for example a slot element, in which a male element, for example a pin, grips.
• a pin connection generally comprises an elastic interlocking male and female element for this purpose an additional elastic element can be provided, but this is not necessarily the case.
• the elasticity can also arise from the design of the male and female elements.
• a hook connection there are typically two elements with a design such that they hook into one another. This does not involve an elastic element and the connection is dismantled by moving the elements away from one another in the correct direction.
