Description

Roof equipment for a roof

[0001] Technical field

The invention is in the field of roof devices for retractable roofs. In particular, the invention provides a roof device comprising slidable roof panels. The invention also relates to a covering comprising the roof device.

[0003] State of the art

A terrace covering is a construction typically made up of columns and beams that is freestanding or mounted on a facade. A roof is then attached to or on the beams. This can 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 of which the surface is almost horizontal, without slope. The roof infill of a retractable roof can, for example, consist of a roll-up cloth or screen, slats that rotate around their axis and may also be slidable, or of segments that can slide over each other. The segments can be panels that are partly made of (laminated) glass or plastic, such as PC or PMMA. Depending on the choice of material, the light transmission and robustness of the roof can be adjusted to the desired application.

Existing roof infills, however, typically suffer from the following problems: A sloped roll-up fabric has a risk of water pocket formation and cannot handle a snow load. A relatively large slope is required for water drainage (+- minus 8°). Moreover, there are only limited infill options and there is no flexibility in changing the aesthetics of the infill. The cloth also gets dirty easily. - Pivotable and/or slide-open slats are not translucent (glass slats that are, are limited in the number of pieces that are possible in a covering). Moreover, there are only limited infill options and there is no flexibility in changing the aesthetics of the infill. The bottom feels typically chilly. - A sliding panel roof typically suffers from slope and curvature problems. It is usually not translucent. In addition, there is usually only one limited infill option and there is no flexibility in changing the aesthetic of the infill. The bottom feels typically chilly. - A sliding panel roof with fabrics is not waterproof and cannot withstand snow loads. There is a risk of bagging and soiling of the fabric.

- A sliding glass roof has a visible slope and does not reflect the sun. In addition, there is usually only one limited infill option and there is no flexibility in changing the aesthetic of the infill. - A fixed canvas span roof is not a movable roof infill and is not translucent.

Other shortcomings of modern retractable flat roofs are (splash) waterproofing and water drainage. The connection between adjacent panels can sometimes be limited, creating gaps and allowing rainwater to leak through the roof. The dirty rainwater can contaminate both the underside of the roof and the terrace below. The risk of incorrect connection increases when the roof is repeatedly opened and closed, for example when dirt or leaves get between the panels. Good water drainage is particularly difficult to achieve for completely flat roofs where water cannot drain off naturally. For example, the standing water can exert pressure on the roof surface due to the formation of water pockets, with the risk of damage, local collapse or leakage. A similar problem can arise during snowfall, where the roof will be placed under heavy loads for a long time followed by local accumulation of melting snow water. In addition, sliding open a wet roof can cause all the dirty water to fall on the terrace below.

There is thus a need for a roof device which offers a solution to one or more of the foregoing problems.

[0008] Description of the invention

It is an object of the present invention to solve or at least partially remedy one or more of the aforementioned drawbacks of flat roofs.

To this end, the present invention relates to a roof arrangement for a canopy, the roof arrangement comprising a panel arrangement and a screen arrangement, the screen arrangement being located below the panel arrangement, the panel arrangement comprising a plurality of stackable panels slidable between an open position and a closed position, wherein the panels form a substantially watertight roof in their closed position, and wherein the screen device comprises at least one screen that is movable between an open position and a closed position, the screen being substantially not visible in its open position and screen in its closed position almost completely covers the panels.

Such a roof arrangement has an increased number of possible configurations with regard to light transmission and/or watertightness and in particular combines the advantages of a panel arrangement and a screen arrangement. Specifically, the following configurations are possible: - Both the panel arrangement and the screen arrangement are open, so that the roof arrangement is maximally open. A lot of light is possible and there is also sufficient ventilation.

- The panel device is closed and the screen device is open. The roof design is watertight and determines the light transmittance in itself. In the case of a glass panel device, there is sufficient incidence of light since the screen device is still open.

- The panel device is open and the screen device is closed. The screen device then serves as sun protection, while there is still sufficient ventilation in view of the open position of the panel device. - Both the panel device and the screen device are closed, so that the roof device is both watertight and sun-resistant. Optionally, the roof device also allows for further positions in which the panel device and/or the screen device are located between their open and closed positions. This again increases the options to obtain the desired light transmission and/or watertightness.

In one embodiment, the roofing device comprises a pair of beams facing each other, each beam comprising: a rail system configured to guide the panels between their open and closed positions; and a screen guide configured to guide the screen between its open and closed positions. In this embodiment, a single rail system is provided for both the guidance of the panels and the screen. This contributes to the simplicity and integration of the roof design.

In one embodiment, the roof device comprises a control system configured to control, in particular control independently of each other, the panel device and the screen device. The control system may be a manual control system, wherein a user causes the panels and/or the screen to move directly or indirectly. Preferably, the control system is a motorized control system. A motorized control system will typically include a motor and a control means which converts the movement of the motor into movement of the panels and/or the screen.

In one embodiment, the roof device comprises a substantially rectangular frame on which/in which the panel device and the screen device are mounted. The use of the same frame for mounting 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.

In an advantageous embodiment, the frame comprises a pair of first beams and a pair of second beams which together form substantially a rectangle, the first beams being opposite each other and the second beams being opposite each other. In particular, the first pair of beams may serve to hold the rail system as described above and/or the second pair of beams may be provided with a housing for holding the screen in its open condition and/or at least one panel of the plurality of panels are fixedly attached to one of the second pair of beams. Building up the framework of the roof device from parallel beams substantially simplifies the construction of the roof device in that different functions are performed by the pairs of beams. In a preferred embodiment, each of said pair of first beams is provided with a gutter adapted to collect precipitation discharged. of the panel device. Preferably, the gutter is located between the rail system and the screen guide. In this embodiment, a water outlet is provided on at least two opposite sides of the panel arrangement so that incident precipitation can be diverted to the frame without landing on the screen arrangement, which could possibly cause damage, for example damp spots.

In one embodiment, the plurality of panels are divided into two sets arranged relative to each other, which sets are preferably symmetrical with respect to each other such that, in their closed condition, they each form substantially one half of the roof, and wherein said at least one screen is formed by two screens arranged relative to each other, which screens are preferably symmetrical with respect to each other so that, in their closed condition, they each cover substantially half of the roof.

In the first place, this provides a symmetrical appearance of the roof device, which is aesthetically pleasing. In addition, this allows to obtain a larger surface area of the roof device while limiting the stacked height of the panels as there are two stacks of panels in the closed state as opposed to only one stack in the more common embodiments. Furthermore, this once again increases the possible configurations with regard to light transmission and/or watertightness, since the panel device and/or the screen device can also be arranged half open/closed.

In one embodiment said at least one screen is formed by two or more screens, which screens are preferably located with respect to each other at opposite ends of the roof device, further preferably the screens are symmetrical with respect to each other so that, when closed, they each cover nearly half of the roof.

[0019] The advantage of using several screens is that the same surface can be covered with smaller screens. Hence there is also less tendency for the screens to sag and the space required for the screens in their open condition is also smaller as a smaller diameter screen roll can be used.

In one embodiment, the sliding direction of the panels is almost identical to the sliding direction of the screen.

Although it is possible to take the sliding direction of the panels and the screen different, e.g. a screen sliding direction that is perpendicular to the panel sliding direction, it is preferable to take both sliding directions the same. The guides for both the screen device and the panel device can in this way be provided in the same beam, which simplifies the integration. It is also possible to provide the screen, in its open condition, under the open panel arrangement, while this is no longer possible with different sliding directions. In addition, there is also an aesthetic aspect.

In one embodiment, the screen can be rolled up and down, the open position being formed by the screen in its rolled-up state and the closed position being formed by the screen in its unrolled state.

In one embodiment, the panels, in their closed position, are aligned next to each other in the same plane and the panels, in their open position, are stacked aligned one above the other.

In one embodiment, the panels comprise a connection element and a connection point, the connection element of each panel being adapted for coupling and uncoupling with a connection point of an adjacent panel.

In one embodiment, the panels comprise a panel frame and a panel infill which, preferably, is secured to the panel frame with a leak-proof seal.

In an advantageous embodiment, the panel infill is translucent and/or transparent.

In an advantageous embodiment, the screen is sun-resistant and/or reflective.

In one aspect, the invention relates to a retractable roof comprising a roof device according to one or more embodiments as described herein. The roof will typically include a roof framing to which the rail system may be mounted.

In one aspect, the invention relates to a patio cover comprising a retractable roof according to one or more embodiments as described herein. The patio cover will typically comprise columns and beams on which, on or in which the retractable roof can be placed.

In one aspect, the invention relates to a use of the roof device as a roof infill for a terrace covering.

The invention generally relates to a roof device comprising a plurality of stackable panels movably arranged along a rail system (i.e. a panel device) under which a screen device is present. This device may be suitable for a sliding structure, such as a sliding roof. The invention relates to a roof device for a retractable roof. The roof device is particularly suitable for a flat sliding roof. A flat roof is a roof of which the roof surface is almost level; i.e. with an inclination of less than 10° and preferably less than 5°, for example less than 2° or 1°. The individual panels, in particular the panel infills, can for instance have a curved surface without mutual height difference. A roof device refers to a movable device for filling in a roof frame. When the movable roof device is mounted in a roof, we can speak of a sliding roof. The sliding roof can form part of a construction comprising a roof structure with an opening and upright walls, such as a terrace roof, pergola, carport and the like. By sliding open is meant that the roof can slide both open and closed. The movable device will be mounted in the roof in such a way as to allow movement between at least two positions, namely a first, closed roof position and a second, open roof position. Optionally, the roof device can be adapted to move to one or more intermediate positions in which the roof is only partially open, for instance half open or a quarter open.

The screen device comprises at least one screen, in particular a retractable and unrollable screen. The screen arrangement is located below the panel arrangement and is movable between an open position and a closed position mainly for controlling the incidence of light. In the closed position of the screen device, the panels are covered, i.e. hidden from view.

The panel arrangement comprises at least a plurality of panels which will form the roof infill. A panel is a rigid structure that will form a part or segment of the roofing device; reference can therefore also be made to a roof panel. A panel will typically have a beam or block-like structure consisting of six substantially rectangular surfaces; namely, an upper face, a lower face (or base), and four side faces. The bottom surface is preferably substantially the same size as the top surface. The term substantially should be interpreted as the referenced body or structure substantially approximates the referenced geometric shape; i.e., except for any roundings, bends, projections, connectors, grooves, slots, ridges, openings, connectors, reinforcing means, and the like; for further clarification reference is made to the figures.

Any reference to an orientation of the panels will be interpreted with reference to the position when mounted in the roof or the roof frame: the bottom panel wall or bottom wall is the panel wall which is oriented towards the ground plane (the earth, eg the terrace floor). or will be, while the top panel wall or top wall is the panel wall which direction the top surface (the sky, eg the open sky) is or will be oriented. Any reference to a direction of the panels shall be interpreted with reference to the direction of movement of the panels along the rail system from the open roof position, where the panels are stacked one above the other, to the closed roof position, where the panels lie side by side in the same plane. Thus, a panel will move forward from its roof open position to its roof closed position, and equivalently, a panel will move backwards from its roof closed position to its roof open position. For further clarification, reference is made to the figures and examples. Throughout the text, the terms -side, -wall, -side, -face can be used interchangeably; for example top, top, top wall, top surface are to be considered equivalent. The rail walls are the remaining side walls of the movable panels which are oriented towards the rail system (mounted on either side of the roof frame) and are preferably in contact with a part of the rail system. The panel wall infills may be partially or fully curved (i.e. curved surface); for example, an arcuate surface of the top panel wall infill can provide improved water drainage to the sides of the roof.

The movable panels are preferably stackable; they can be stacked on top of each other. The movable panels are stackable with a (fully) open roof position. Preferably, the panels are stacked aligned one above the other. An aligned stack means that the stack has virtually no deflections; i.e. two adjacent panel walls in the open position will substantially completely cover each other in the stacked position. As a result, in the open roof position, the closed roof space can be limited to the surface of only one panel. This is different from other roof designs where often only part of the panels can slide (for example where only one panel slides onto a second panel), and/or the panels can only partly slide over each other (for example where the panels project on one side and form a stair structure), limiting the size of the open roof space. In addition to an aesthetic improvement, the current roof design will also be able to provide more light in an open roof position. Optionally, the stacked panels can lie on top of each other; in this case the upper or lower panel walls of upper or lower panels will come into contact with each other. In a stacked position, the weight of the upper panels can be absorbed by the underlying panels, or the weight of each panel can be absorbed separately by, for example, the rail system and/or additional support elements, or a combination of both.

The movable panels are preferably coplanar alignable; they can be aligned in the same plane. The movable panels are aligned in the same plane with a (completely) closed roof position. In the same plane means that the panels lie in one plane, whereby the panels are arranged next to each other at almost the same height (no staircase structure) in a straight line (no curvature). The interface of the top and/or bottom surfaces of each panel will continue into the respective top and/or bottom surfaces of the adjacent panels when the roof is fully closed; i.e. excluding any projections (e.g. reinforcing elements) or openings (e.g. gutters for water drainage, or for placement of lighting) provided in the upper and/or lower panel walls; for further clarification reference is made to the figures.

There can be numerous variations on the dimensions of the panels and consequently also on the dimensions of the roofing device. The dimensions can be adapted to, among other things, the size of the roof, the amount of movable panels, the material from which the panels are made, and so on. By way of example, a panel may have a length of at least 0.50 m to at most 5.00 m; such as 2.00m, 2.50m, 3.00m, 3.50m, 4.00m, 4.50m and so on. By way of example, a panel may have a width of at least 0.50 m to at most 3.00 m; such as 1.00m, 1.50m, 2.00m and so on. By way of example, a panel may have a height of at least 1 cm to at most 50 cm; such as 5cm, 10cm, 15cm, 20cm, 25cm and so on. In an exemplary embodiment, a roof with the following dimensions is considered: 4.50 mx 6.20 m. In a first example, this roof can be filled in by 6 movable panels, where each panel is 950 mm x 4200 mm (after deduction of the frame in which the illustrative roof infill is mounted will be). In a second example, this same roof can be filled in by 8 panels, with each panel measuring 715 mm x 4200 mm. The advantages and disadvantages of the different sizes are believed to be known to those skilled in the art. Alternatively or additionally, several roof devices can also be placed alongside or opposite each other in separate rows and/or columns. As a result, there is in principle no limitation on the maximum roof surface that must be filled in.

The panel frame - or frame as used herein - refers to a rigid structure suitable for supporting and preferably framing a panel infill. The frame includes at least one frame profile. A frame profile - or profile as used herein - refers to a rigid and preferably elongate body, typically used as a frame framing. Depending on the desired embodiment, a profile can be rounded as well as flat, with a wide or narrow wall, be hollow or filled on the inside with a filling material, be ribbed or smooth, and/or have ornamental 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 skilled person is believed to have sufficient knowledge to adapt the panel frame to the desired embodiment. The profiles are typically made of a rigid material. This can be aluminum for example. Aluminum has many advantages as a profile material, because it is robust and light at the same time, resistant to adverse weather conditions and requires little maintenance. However, other materials are also suitable and their advantages or disadvantages are believed to be known to those skilled in the art. A profile can be produced using different techniques depending on the material, including extrusion, milling, setting, casting, welding, and so on. The appropriate manufacturing technique is believed to be known to those skilled in the art.

The frame typically has a substantially quadrangular, preferably rectangular, shape. The frame can be formed by a single frame profile bent several times. However, it is easier and more efficient to produce multiple frame profiles and then link them together to form the frame. The panel frame will typically comprise four profiles; in particular two main profiles which are typically arranged at the front and rear of the roof panel and thereby form the front and rear wall, and two side profiles which are typically arranged at the end face of the roof panel and thereby form the side walls. Typically, the front and back of the roof panel will be formed by the long sides of the roof panel and the front end by the short sides. The skilled person understands that, depending on the desired embodiment of the roof panel, this can also be the other way around, in particular that the front and back of the roof panel will be formed by the long sides of the roof panel and the front side by the short sides. The main profiles and side profiles are discussed in more detail below.

The panel infill will typically form the top of the roof panel and, when mounted in a roofing device, will also form the top of the roof. The panel infill will provide the watertight shielding of the roof. The panel infill is made of a watertight material which is preferably mounted or mountable in the panel frame under a slope and/or with a certain convex bend. As a result, the water that ends up on the roof panel will be able to run off along the sides of the roof frame, without landing on the screen device located below it, which could possibly leave markings, damage or permanent traces.

The panel infill will typically be a sheet which fills in the space of the panel frame; preferably the entire space between the main profiles of the panel frame. The panel infill can be made from different materials or even combinations of materials. The choice of materials can be adapted to, among other things, the size of the roof (rigidity), the application of the roof design (translucent or light-blocking), the climate in which the construction is placed (mainly sun, rain or snow), and so on. By way of example, the panel infill may be made of metal (e.g. aluminum), plastic (e.g. PC, PMMA, PVC), (laminated) glass, etc., and/or combinations of different material types. Optionally, the panel infill can be coated, for example with a water-repellent coating. The advantages and disadvantages of the different types of materials and coatings are believed to be known to those skilled in the art. In particular, the panel infill may be made of a layered structure whose layers, especially transparent layers, may contain the same or a different material. The advantage of such a layered structure is the structural reinforcement of the panel infill for the same or more limited height so that external loads such as snow are better supported with limited and/or permanent deflection. An example is the use of laminated glass, where the glass panels have a thickness of 3 mm and the plastic intermediate layer has a thickness of 0.2 mm.

The panel infill can be light blocking, light transmissive or optically transparent. By light-blocking is meant that the panel infill blocks the visible light almost completely; for example, transmits at most 5% of visible light; preferably at most 3%; more preferably at most 1%. Translucent is understood to mean that the panel infill partially transmits visible light but also partially blocks and/or scatters it; for example transmitting at least 10% of the visible light or for example scattering at least 90% of the visible light; for example transmits at most 90% of the visible light or, for example, scatters at least 10% of the visible light. Optically transparent is understood to mean that the panel infill allows the visible light to pass almost completely; for example, transmitting at least 90% of the visible light or scattering at most 10% of the visible light; preferably transmits at least 95% of the visible light or scatters at most 5% of the visible light; more preferably transmitting at least 98% of the visible light or scattering at most 2% of the visible light; more preferably transmits at least 99% of the visible light or scatters at most 1% of the visible light. It is also possible to apply patterns, logos, motifs, etc. to the panel infill by manufacturing the panel infill from light-blocking, light-transmitting and/or optically transparent zones.

A surface of the panel infill may be curved. Preferably the surface of the panel infill will be convex. Convex as used herein means that the surface is curved outward. The convex surface will typically form the top of the roof panel. The convex shape has the advantage that the rain and/or snow water will run off towards the side profiles of the panel for improved water drainage.

The convex surface may be arcuate. Arc-shaped as used herein means that the surface of the panel infill is curved outwardly like the perimeter of a circle. The convex surface may be circular or spherical. Spherical as used herein means that the surface of the panel infill is curved outwardly like the perimeter of a sphere. An arcuate or spherical surface will provide improved water drainage. The curve of the convex surface may optionally deviate partially or completely; for example to form an elliptical or oval-shaped surface.

The radius of curvature (R) of the curved surface is at least 1 m to at most 150 m. The radius of curvature is preferably 5 m to 100 m; more preferably 10 m to 80 m; more preferably 20 m to 60 m; more preferably 30 m to 40 m; for example 31 m; for example 32 m; for example 33 m; for example 34 m; for example 35 m; for example 36 m; for example 37 m; for example 38 m; for example 39 m. The skilled person understands that the radius of curvature is calculated as a radius of curvature interval based on the R-test, where the length corresponds to the chord of the curved panel infill and the height is measured from the highest (middle) point to the chord . Optionally, the top can be supported or provided internally.

The top of the curved panel infill may be at least 10 mm to at most 50 mm higher than one end of the panel infill at the end faces of the roof panel. The top is preferably at least 10 mm to at most 45 mm higher; more preferably 10mm to 40mm; more preferably 15mm to 35mm; more preferably 20mm to 30mm; e.g. 25mm.

A surface of the panel infill may be inclined. The slope has the advantage that the rain and/or snow water will run off towards the side profiles of the panel for improved water drainage. Preferably, the surface of the panel infill will form a gable roof. The term "gable roof" as used herein means that the panel infill consists of at least two pitched panel infill members placed against each other and intersecting in a ridge. The parts are preferably coupled together in the ridge to obtain a stable structure. The sloped panel infill members are preferably of equal length; in other words, the panel infill forms a symmetrical gable roof. Alternatively, a single panel infill can form a gable roof by being bent at least one point; the inflection point will form the ridge. Optionally, the top of the ridge can be internally supported or provided. The gable roof shape has the advantage that the rain and/or snow water will run off towards the side profiles of the panel for improved water drainage.

The slope of the panel infill may have a slope of at least 0.5° to at most 5.0° from the ridge to one end of the panel infill at the end faces of the roof panel. The slope 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 about 1.5°; for example 1.3°.

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

The panel infill is preferably secured to the panel frame by clamping the body of the panel infill through the frame profiles. The frame can thereby form a space suitable for receiving the panel infill. Preferably, the panel infill will be clamped along at least a top and a bottom. An edge, preferably all edges,

of an upper surface and/or lower surface of the panel infill can be partially, preferably completely covered by the frame profiles. Alternatively or additionally, the panel infill can be clamped along the sides. Preferably, the sides of the panel infill will be completely covered by the frame profiles.

The clamping of the panel infill can be achieved by providing the main profiles and/or side profiles with a U-profile (also known as C-profile), whereby the distance between the upright walls of the U-profile (also known as the height) almost corresponds to the thickness of the panel infill. By sliding the panel infill between the upright walls, it will remain clamped after connecting adjacent profiles.

The clamping of the panel infill can be achieved by providing the main profiles and/or side profiles with two clamping profiles, wherein a clamping profile will contact a top side of the panel infill and a second clamping profile will contact a bottom side of the panel infill. The clamping profiles can then be coupled to an upright side wall of the main profiles and/or side profiles to clamp the panel infill.

The panel infill may be secured to the panel frame with a leak-proof seal. Preferably, when clamping the panel infill, the seal will close all free spaces and thereby prevent potential leaks of rain and snow water. The seal can be placed between the frame and the panel infill. The seal can also be placed between individual frame profiles. The seal is typically made of a compressible material. This can be, for example, plastic or rubber. Alternatively, the seal can be realized by curable materials such as silicone.

The panel frame may further include a drainage slot for downward drainage of rain or snow water that preferably slopes laterally from the top of a panel infill. A drainage trench can be formed by producing the length of the panel infill less long than the corresponding length of the main profiles of the panel frame against which the panel infill will be attached. This creates an elongated opening during assembly between one side of the panel infill and a side profile of the panel frame along which the water can drain. A downwardly directed drip-nose profile can be attached to the side of the panel infill, which can contribute to shielding the underlying screen device against downwardly running water. In an advantageous embodiment, both lateral profiles will form a drainage slot on both sides of the roof panel, preferably with a drip-nose profile attached to both sides of the panel infill.

Optionally, when mounting the roof panel in a roofing device, the drainage slot can be placed above a roof frame gutter of the roofing device or roof construction for improved water drainage to prevent leaks on the base of the roofing device such as the terrace. By keeping the width of the drainage slot smaller than the gutter width of the roof frame gutter, the waterproofing can be hidden from view.

The panel frame may further comprise a roof panel gutter for lateral drainage of rain or snow water which preferably slopes laterally from the top of a main profile. A roof panel gutter can be formed by providing a main profile with a sloping structure at one end of the main profile. As a result, when the roof panels are mounted in a roof device, a roof panel gutter is created between two adjacent roof panels, in particular between two adjacent main profiles of two adjacent roof panels, i.e. between a front main profile of a first roof panel and a rear main profile of a second roof panel. The laterally draining water can then drain downwards via the above-described drip nose, preferably along the above-described drainage slot, or a separate drainage opening can be provided on the side of the main profile.

The roofing device may further comprise a roof framing gutter for lateral drainage of rain or snow water which preferably slopes laterally from the top of a roof panel. The roof framing gutter may comprise an elongated beam-shaped or semicircular structure typically communicating with a vertical drainpipe. The roof frame gutter prevents the drained water from falling directly from the roof onto the underlying terrace or ground.

The roof frame gutter can be a separate structure that hangs from or communicates with a panel frame. Alternatively, the roof frame gutter can be integrated into the panel frame. The roof frame gutter will be designed to collect the running water from a roof panel. The roof frame gutter can be arranged along the roof panel, wherein the roof frame gutter preferably connects to one end of the roof panel. The roof frame gutter can be arranged under a roof panel, wherein the roof frame gutter is preferably arranged below one end of the top roof panel. The roof frame gutter can be arranged under a drainage slot of an upper roof panel. The roof frame gutter can hang below the roof panel above.

The roof frame gutter can be arranged under a drip-nose profile of an upper roof panel. The roof frame gutter can comprise an upright wall to guide the water. The upright wall may have a raised top edge to prevent overflow of the discharged water. The top edge may be raised to be higher than or at least at the same height as the bottom edge of a drip-nose profile of an overhead roof panel. This has the advantage that water splashes from running water are collected, preferably via the drainage slot. Moreover, this will also prevent a light gap from arising on the side of the roof device as a result of the presence of a drainage slot.

[0093] EXAMPLES

Reference is made to the figures by way of example. The embodiments illustrated in the figures are preferred embodiments of the present invention and should not be construed as limiting in any way.

[0095] Example 1: Single track rail system

Figure 1 shows a schematic view of a roof device (100) comprising three panels (200) arranged movably along a single track rail system (310). The movable panels will move in one and the same plane; preferably slidable.

In a first, open roof position (Figure 1(a)) all movable panels (200) are stacked aligned one above the other: the top panel wall of the first, bottom panel (201) is completely covered by the bottom panel wall of the second adjacent panel (202); and the top panel wall of the second panel (202) is completely covered by the bottom panel wall of the third, top panel (203). In Figure 1(b), a first lower panel (201) will be actuated to move movably along the single track rail system (310) in the forward direction (i.e. toward the front panel wall); this forward direction of movement is indicated by a dashed arrow. When the first panel (201) is completely below the stacked panels (200), the second panel (202) will move downwards to land next to the first panel (201) on the single track rail system (310) (Figure 1( c)); this downward direction of movement is indicated by a dashed arrow. The second panel (202) will be able to move forward together with the first panel (201) (Figure 1(d)). This will also allow the third, top panel (203) to move downwards. All movable panels (200) have moved sequentially (203) forward and/or downward until all movable panels (200) are aligned next to each other in the same plane (and preferably abut each other) (Figure 1(e)). The first, bottom panel (201) has become the front panel (201); and the third, top panel (203) has become the rear panel (201).

Figure 2 shows a schematic depiction of a roof device (100) comprising three panels (200) arranged movably along a single track rail system (310), the roof device (100) further comprising a connection system. The terminal system includes a terminal element (220) and a complementary terminal (225); each movable panel (200) adapted to mate with adjacent panels includes a downward facing terminal member (220) arranged on a front panel wall and an upward facing terminal point (225) arranged on a rear panel wall. The single track rail system (310) includes a lower (311) and an upper (312) guide rail which extend in a direction along which the retractable roof will slide open and closed. For simplicity, only the guide rails of one side of the rail system are shown in the picture; the guide rails arranged on the opposite side of the roof frame are not shown. At a first end in the direction of the rear panel walls, the guide rails run (obliquely) upwards so that the panels can be stacked aligned one above the other. Each movable panel (200) is preferably provided with at least one roller bearing per guide rail (311, 312): at least four roller bearings in total.

Equivalent to the example described above, in Figure 2(a), the movable panels (200) are stacked in alignment one above the other. The first panel (201) will advance along the guide rails (311, 312) of the single track rail system (310) (Figure 2(b)). Due to the forward movement, the connection point (225) arranged on the rear panel wall of the first panel (201) will overlap with the connection element (220) arranged on the front panel wall of the second panel (202) (Figure 2(c)). This will allow the second panel (202) to move downwards (Figure 2(d)). The downward movement of the second panel (202) will cause the second panel to lie in the same plane as the first panel (201) and will couple the two panels (201, 202) to each other by hooking the connection element (220) of the second panel (202) with connection point (225) of the first panel (201) (Figure 2(e)). This coupling (circled) will ensure that with a further forward movement of the first panel (201), the first panel (201) will be able to pull the second, coupled panel (202) along in the same forward movement direction. Equivalent to the above, the third panel (203) will be able to couple with the second panel (202) whereby the third panel (203) will also be pulled along by the forward movement of the first panel (201) (Figure 2(f)).

Figure 3 shows a detailed depiction of a first movable panel (201) including a terminal system. The terminal system includes a terminal member (220) arranged on a front panel wall of the panel (201) that can mate with a complementary terminal mounted on a rear panel wall of another panel (not shown). The terminal member (220) includes a downwardly directed hook-shaped body extending forwardly from the front panel wall; the hook-shaped body has an L-shaped profile with a downwardly directed hook structure. The connection system further includes a connection point (225) arranged on a rear panel wall of the panel (201) that can mate with a complementary connection element arranged on a front panel wall of another panel (not shown). The connection point (225) includes an upwardly directed hook-shaped body extending rearwardly from the rear panel wall; the hook-shaped body has an L-shaped profile with an upwardly directed hook structure. The first panel (201) further includes a set of roller bearings to allow movement along rails.

Figure 4 shows a detailed depiction of a coupling between two adjacent panels, namely a first panel (201) and a second panel (202). The rear panel wall of the first panel (201) engages the front panel wall of the second panel (202) in that the connection member (220) of the first panel (201) hooks onto the complementary connection point (225) of the second panel (202) . In this example, there are no gaps between the two adjacent panel walls of the two joined panels (201, 202). Both the top surface and the bottom surface of the coupled panels form an almost continuous and contiguous surface.

[0102] Example 2: Multi-track rail system

Figures 5 and 6 show schematic views of two embodiments of roofing devices comprising three panels (200) arranged movably along a multi-track rail system (320). The panels (200) will be able to move in different but parallel planes.

Figure 5 illustrates a first embodiment where the movable panels will move stacked one above the other through the rail system. In a first, open roof position, all movable panels (200) are stacked one above the other (Figure 5(a)). The lowermost panel (210) is fixed, it cannot move along the rail system (320). The first movable upper panel (201) will be actuated to move in the forward direction along the first uppermost part (321) of the multi-track rail system (320) (Figure 5(b)); this forward direction of movement is indicated by a dashed arrow. A forward movement of the first panel (201) may cause the underlying movable panels (202, 203) to move in the same forward direction; these underlying movable panels can for instance be pulled along by the first panel (201). Alternatively, the underlying movable panels (202, 203) can each be controlled separately. Due to the forward movement, third movable lower panel (203) will no longer be stacked above the fixed panel (210) and will be able to move downwards (Figure 5(c)); this downward direction of movement is indicated by a dashed arrow. The downward movement will cause the third movable panel (203) to come in the same plane as the fixed panel (210) so that the panels are aligned next to each other (Figure 5(d)). The remaining movable panels will move forward until all movable panels (200) are aligned next to each other in one and the same plane (and preferably abut each other) (Figure 5(e)).

Figure 6 illustrates a second embodiment where the movable panels will move separately through the rail system. Figure 6(a) is equivalent to Figure 5(a), except that each movable panel (200) will be controlled separately. By way of example, in Figure 6(b), the third movable lower panel (203) will be first actuated to advance along the multi-track rail system (310). The third movable lower panel (203) will move forward until it is no longer stacked over the attached panel (210) and will be able to move downward (Figure 6(c)); this downward direction of movement is indicated by a dashed arrow. The downward movement of the third panel (203) will cause the third panel (203) to be coplanar with the attached panel (210) (Figure 6(d)). Simultaneously or subsequently, by way of example, the second panel (202) will be actuated to move along the multi-track rail system (310) in the forward direction. Each remaining movable panel will move forward individually until all movable panels (200) lie side by side in one and the same plane (and preferably abut one another) (Figure 6(e)).

Figure 7 shows a schematic illustration of a roof device comprising three panels (200) arranged movably along a multi-track rail system (310), the roof device further comprising a connection system.

The terminal system includes a terminal element (220) and a complementary terminal (225); each movable panel (200) adapted to mate with adjacent panels includes a downward facing terminal member (220) arranged on a front panel wall and an upward facing terminal point (225) arranged on a rear panel wall. The multi-track rail system (320) includes a plurality of parallel arranged guide rails; namely, a front and a rear guide rail per movable panel (200) extending in a direction along which the sliding roof will slide open and closed. For simplicity, only guide rails from one side of the rail system are shown in the picture; the guide rails arranged on the opposite side of the roof frame are not shown.

Each movable panel (201,202,203) is provided with at least one roller bearing per guide rail, i.e. at least four roller bearings in total. The lowermost panel (210) is attached; it cannot move along the rail system (320). The first panel (201) is supported by a first front (331) and a first rear guide rail (341), the second panel (202) by a second front (332) and a second rear guide rail (342), and the third panel (203) by a third front (333) and a third rear guide rail (343). The front guide rails (331-333) are sideways oriented guide rails which merge into a diagonal orientation. The rear guide rails (341-343) are diagonally oriented guide rails which transition into downward orientation.

Equivalent to the example described above, in Figure 7(a), the movable panels (200) are stacked completely one above the other. The third movable lower panel (203) will, by way of example, be the first to move forward over the guide rails (333,343) of the multi-track rail system (320) (Figure 7(b)). The third panel (203) will continue to move forward until the connection element (220) arranged on the rear panel wall of the third panel (203) will overlap with the connection point (225) arranged on the front panel wall of the fastened panel (210) (Fig. 7(c)). This will allow the third panel (203) to move downwardly so that the terminal member (220) of the third panel (203) will engage with terminal (225) of the attached panel (210) (Figure 7(d)). The third panel (203) will come to lie in the same plane adjacent to the fastened panel (210). Subsequently, the second movable panel (202) will also move forward over the guide rails (332,342) of the multi-track rail system (320) until the second panel (202) can engage with the third panel (203) in a similar manner (Figure 7(e). )); namely, by coupling the connection element (220) of the second panel (202) to the connection point (225) of the third panel (203). The remaining panels in turn will also move forward until all movable panels are aligned next to each other in one and the same plane (and preferably abut one another) (Figure 7(f)).

[0110] Example 3: Connection System

The advantages of a connection system for use in a roof installation have already been described in example 1 for a single-track rail system and in example 2 for a multi-track rail system. Example 3 describes a preferred embodiment of the connection system.

Figures 8A and 8B show schematic views of two embodiments of roofing devices (100) depicting a coupling between two adjacent panels (201, 202), the connection element (220) of the first panel (201) coupling to the complementary connection point (225) of the second panel (202).

The junction (225) includes a first body extending laterally forward from the front panel wall of the second panel (202). At right angles to the end of the first body is an upwardly directed second body. The upwardly directed second body extends diagonally towards the front panel wall of the second panel with a low angle of inclination. The end of the second body is curved so that at least a portion of the second body will extend back toward the front panel wall of the second panel. The two bodies can also be seen as one continuous body with one or more bends.

The terminal member (220) includes a first body extending laterally rearwardly from the rear panel wall of the first panel (201). At right angles to the end of the first body is a downwardly directed second body. The downwardly directed second body is partially curved to form a stepped surface having a structure corresponding to the surface of the complementary terminal (225). The end of the second body is curved so that at least a portion of the second body will extend back toward the rear panel wall of the first panel. This shape will ensure that when the first panel (201) moves downwards on the second panel (202), the connection element (220) will be able to hook into the connection point (225) for connecting the two coupled panels (201, 202) . The first panel (201) further includes a reinforcing member (290) which includes an upwardly facing body extending laterally from the rear panel wall of the first panel (201). The reinforcing element (290) is connected to the connection element (220); in particular with a first portion of the body of the terminal member (220) extending rearwardly from the rear panel wall of the first panel (201). The reinforcing element (290) is perpendicular to the top surface of the first panel (201). The coupling between the connection element (220) of the first panel (201) and the connection point (225) of the second panel (202) will allow the reinforcing element (290) to support and load the second panel (202) on the top surface of the roof equipment will be able to be spread over the plurality of linked panels.

In particular, Figure 8A shows a first embodiment in which a slide-on clip (230) was placed on one end of the terminal member (220). In this embodiment, the connection element (220) will slidably engage the connection point (225). This clip (230) will contact one end of the connection point (225) of the second panel (202) during coupling, which will allow the body of the connection point (225) to slide over the clip (230). The clip (230) will limit the friction between the bodies of the connection element (220) and the connection point (225) and thereby improve the coupling/disconnection. The clip (230) can be made of a variety of materials, including a plastic with a low coefficient of friction, such as Teflon or PTFE. Alternatively or additionally, the clip (230) may also be provided with a coating that lowers the coefficient of friction. The clip (230) can also serve to dampen noises during the closing of the roof device. In particular, the clip (230) prevents two aluminum surfaces from hitting each other during closing, which typically causes noise. Providing a clip (230) of a suitable material prevents such noise.

In particular, Figure 8B shows a second embodiment in which a roller bearing (235) is mounted on one end of the terminal member (220). In this embodiment, the connection element (220) will be able to rollably couple to the connection point (225). This roller bearing (235) will contact one end of the docking point (225) of the second panel (202) during engagement, allowing the body of the docking point (225) to roll over the roller bearing (235). The roller bearing (235) will prevent friction between the bodies of the connection element (220) and the connection point (225) and thereby improve the coupling/disengagement. The roller bearing (235) can be made of a variety of materials, including a plastic with a low coefficient of friction, such as Teflon or PTFE. Alternatively or additionally, the roller bearing (235) can also be provided with a coating that lowers the coefficient of friction. The roller bearing (235), like the clip (230), also serves to dampen noises during the closing of the roof device.

Figures 9A and 9B show perspective views of the first embodiment of Figure 8A (with sliding clip). In addition to the features and components described above, Figure 9A and Figure 9B illustrate the extent of the gaps formed between the rear panel wall of the first panel (201) and the front panel wall of the first panel (201) when coupling the connection point (225) to the connection element (220). The size and shape of the opening can be adapted by changing the shape of the connection point (225) and/or the connection element (220), and/or by the presence of additional panel walls and/or protruding structures.

Figure 9A shows a top perspective wherein on the top surface the upwardly directed opening forms a trough (221) between the front panel wall of the second panel (202) and the connection member (220) of the first panel (201). This gutter (221) can be suitable for lateral rainwater drainage. The gutter runs the full width of the panels (201, 202).

Figure 9B shows a bottom perspective where, on the lower face, the downwardly directed opening forms a gap (226) between the rear panel wall of the first panel (201) and the connection point (225) of second panel (202). This gap (226) may be suitable for housing a luminous element, such as an LED strip, and the necessary electrical wiring, or a decorative element.

Figure 10 shows a schematic illustration of the above-described terminal system according to the second embodiment of Figure 8B (with roller bearing). Figure 10(a) shows a disengaged position in which a terminal member (220) of a first upper panel (201) lands on top of a terminal point (225) of second lower panel (202). This position can be achieved by way of example by a multi-track rail system as described in example 2. In Figure 10(b), a downward movement of the first panel (201) will cause the roller bearing (235) mounted on one end of the connection element (220) come into contact with one end of the connection point (225). The connection element (220) will roll over the body of the connection point (225) until the roller bearing contacts an arcuate bend in the upwardly directed body of the connection point (225), which will clamp the roller bearing (Figure 10(c)) . The rollable coupling between the connection element (220) and the connection point (225) hereby forms an upwardly directed trough (221) and a downwardly directed intermediate space (226) (Figure 10(d)).

Figures 11 and 12 show a schematic depiction of the above-described connection system used in a roof installation comprising a multi-track rail system (310). Figure 11A shows an open roof position in which the movable panels are stacked one above the other.

In the open roof position, the reinforcing elements (290) of the plurality of movable panels (200) will be placed against each other so that the stackability of the movable panels is not limited. Figure 11B shows a closed roof position in which the movable panels are aligned side by side in one and the same plane. The reinforcing elements (290) of the front panels can improve the rigidity of the rear panels. The loads can be shared between the adjacent and linked panels by means of the connection system. In this exemplary embodiment, the fixed (immovable) panel (210) will also include a reinforcing element (290). The reinforcing elements (290) of the plurality of movable panels (200) will form on the top surface of the roof a rib structure which can improve the rigidity of the roof over its entire surface. Figure 12A shows a further embodiment of the roof device of Figure 11A, wherein the first, top panel (201) comprises a second reinforcing element (295) arranged on a front panel wall. The presence of a reinforcing element (290) at each end of the roof can further enhance the rigidity of the roof over its entire surface. Figure 12B shows a detailed view of the stacked panels of Figure 12A.

[0122] Example 4: Stacking System

The advantages of a stacking system for use in a roof installation have already been described in example 2 for a multi-track rail system. In Example 4, a preferred embodiment of the stacking system is further described.

Figure 13 shows a detailed view of a first movable panel (201) including a stacking system. The stacking system includes a downwardly facing engagement member (250) arranged on a lower panel wall of the panel (201) that mates with a compatible recess (245) arranged on an upper panel wall of an adjacent panel (not shown). The depth and width of the notch (245) substantially matches the length and width of the downwardly directed engagement member (250) so that the notch (245) can completely enclose the engagement member (250). The panel (201) also includes such a notch (245) on the top panel wall. The stacking system further includes an upwardly directed guide member (240) arranged on an upper panel wall of the panel (201) which is operable against a downwardly directed projection (250) arranged on a lower panel wall of an adjacent panel (not shown).

Figures 14 and 15 show a schematic depiction of a roof device (100) comprising at least two movable panels (200) arranged along a multi-track rail system (320), the roof device further comprising a stacking system. Figure 14 shows an embodiment of the stacking system in which the movable panels move from an open roof position to a closed roof position. Figure 15 shows an embodiment of the stacking system in which the movable panels move from a closed roof position to an open roof position.

Referring to Figure 14(a), two movable panels (201, 202) stacked on top move forward (i.e. toward the front panel wall) over separate guide rails of the multi-track rail system (320); the forward movement is indicated by a dashed arrow. The first movable panel (201) moves along a first front (331) and a first rear guide rail (341), and the second movable panel (202) moves along a second front (332) and a second rear guide rail (342). The two panels are coupled together by means of the stacking system (circled): the downward projection (250) of the first panel (201) is completely enclosed by the notch (245) of the second panel (202). This coupling allows the second panel to be pulled along by the first panel (201) along the rail system (320) by the forward direction of movement of the first panel (201). The second panel (202) can advance until a front of the second panel (202) contacts one end of the second front guide rail (332) (Figure 14(b)); this end will cause the forward movement of the second panel (202) to be blocked (flat arrow). However, the rear of the second panel (202) will be able to move further downward along a downward facing end of the second rear guide rail (342) (Figure 14(c)). This downward movement of the second panel (202) may cause the engagement between the downward facing projection (250) of the first panel (201) and the notch (245) of the second panel (202) to disengage. The disconnection will allow the first panel (201) to move forward unimpeded again along the guide rails (321, 331) (Figure 14(d)).

In Figure 15(a) shows a first movable panel (201) moving rearwardly (i.e. toward the rear panel wall) along a first front (331) and a first rear guide rail (341); the backward movement is indicated by a dashed arrow. Below the first panel (201) lies a second movable panel (202); for example, this second panel (202) may be aligned in plane with a closed roof position. The first panel (201) will be free to move rearwardly until the downward projection (250) of the first panel (201) contacts the upward projection (240) of the second panel (202) (Figure 15(b)). ). This contact will allow the first panel (201) to push the second panel (202) forward upon further backward movement of the first panel (201) (Figure 15(c)). A rearward movement of the second panel (202) will first cause the second panel (202) to move upwardly along a downward facing end of the second rear guide rail (not shown in the figure). The upward movement will cause the notch (245) of the second panel (202) to fully enclose the downward projection (250) of the first panel (201). The two adjacent panels (201, 202) are coupled together by means of the stacking system (circled). The two joined panels (201,202) can then move backwards together, preferably aligned, stacked one above the other, over separate guide rails of the multi-track rail system (320) (Figure 15(d)).

[0128] Example 5: Roof panel

Figure 16 shows an image of a roof panel (1100) viewed along a top of the panel. The roof panel (1100) comprises a panel frame comprising four profiles: two main profiles (1110), in particular a front main profile (1111) arranged at the front of the roof panel (1100) and thereby forming the front wall and a rear main profile (1112). ) which is arranged at the rear of the roof panel (1100) and thereby forms the rear wall, and two side profiles (1120) which are arranged at the sides of the roof panel (1100) and thereby form the side walls.

The roof panel (1100) further includes a panel infill (1200) attached to the frame. The panel infill (1200) is completely contained in the opening formed by the four profiles (1110, 1120). In this specific example, the panel infill is clamped by a clamping profile (1140) against a main profile (1110); this clamping is discussed in more detail in further figures. The rear main profile (1112) further includes an upwardly directed reinforcing element (1180) extending laterally from the rear main profile (1112).

Figure 17 shows a cross-section of a roof panel (1100) viewed along one side of the panel. In this image only the two main profiles (1110) are visible.

The panel infill (1200) is clamped between the front main profile (1111) and the rear main profile (1112) by means of a plurality of clamping profiles (1140), in particular an upper clamping profile (1140a) and a lower clamping profile (1140b ).

Figure 21A shows the roof assembly (500) in its most open position, namely with both the panel assembly (510) and the screen assembly (530) open. Figure 21B shows a configuration in which the roof device (500) forms a watertight roof because the panel device (510) is closed, but where the light transmission is not or only slightly reduced since the panel device (510) uses glass panels. Figure 21C shows a configuration in which the screen device (530) is partially closed and the panel device (510) is fully closed. In this way, the roof device (500) is watertight and the incidence of light is partially limited. The most closed position of the roof device (500) is shown in Figure 21D where both the panel device (510) and the screen device (530) are fully closed. The roof device (500) is in this way watertight and not translucent.

The construction of the individual panels and/or the construction and operation of the panel device (510), and the associated advantages, are identical to the roof devices described with reference to Examples 1 to 6 and are therefore no longer described here. . The panel device (510) can thus make use of a single-track or multi-track rail system and/or the stacking systems and/or connection systems described therewith and/or the described panels optionally with the described drainage.

Further details of the roof device (500) are described with reference to Figure 22. The roof device (500) comprises a roof frame formed by pivot beams (502) and tension beams (504), generally referred to as beams (502, 504), of which one each is shown in Figure 22. The panel arrangement (510) comprises a plurality of panels (512), three in the embodiment shown, stacked one above the other in their open position (Figure 22A) and in their closed position (Figure 22B). are next to each other in a plane. Preferably, the lower panel (512) is rigidly connected to the tension beam (504), which enhances the watertightness of the panel device (510). The pivot beam (502) is provided with a rail system (not shown) as already described above for guiding the panels (512).

Below the panel device (510) is provided a screen device (530) which includes a screen (532), also referred to as a cloth. The screen (532) can be rolled up and down and, in its rolled up condition, is housed in a housing (534) which is fixedly attached to the tension beams (504). The pivot bars (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) for collecting precipitation discharged from the panel device (510).
