Description

MOVABLE ROOF FITTINGS

TECHNICAL FIELD The invention is in the field of roof devices for slide-open roofs. In particular, the invention provides a roof device comprising slidable roof panels arranged movably along a rail system. The invention also relates to a sliding roof comprising the movable roof device. The invention also relates to the use of the roof device in a roof. The invention furthermore relates to a method for sliding the roof device open and closed.

TECHNOLOGICAL BACKGROUND OF THE INVENTION A patio cover is a construction typically consisting of uprights and girders that is mounted freestanding or on a facade. A roof is then placed on the girders. This can be a fixed roof, but in modern housing there is an increasing demand for retractable roofs, for example retractable flat roofs; i.e. roofs with a surface that is almost horizontal, without slope. The roof infill of a sliding roof can for instance consist of a roll-up cloth, slats that rotate around their axis, or 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. Modern systems, however, only allow a limited finishing of the existing roof infills. It is a first object of the present invention to provide a slide-open roof device with improved finishing options, in particular of the flat bottom of the flat roof. Two important shortcomings of modern retractable flat roofs are (splash) water tightness and water drainage. The connection between adjacent panels can sometimes be limited, creating openings and allowing rainwater to leak through the roof. The dirty rainwater can soil both the underside of the roof and the underlying terrace. The risk of incorrect connection increases when the roof is opened and closed multiple times, 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 naturally. For example, the standing water can exert pressure on the roof surface due to the formation of water, with the risk of damage, local subsidence, or leakage. A similar problem can arise with snowfall, where the roof will be subject to heavy loads for a long time followed by local build-up of melting snow water. In addition, sliding open a wet roof can cause all the dirty water to fall on the underlying terrace. It is a further object of the present invention to provide a slide-open roof arrangement with improved water tightness and / or water drainage.

The opening and closing of the roof can be manually driven, but it can also be motorized. However, motorized systems are complex and require separate control of each movable panel. As a result, there is more chance of defective parts. In addition, a defective part can partially block the correctly functioning panels, causing the entire drive to stop. It is a further object of the present invention to provide a roof device that is simpler in both assembly and use, with in addition a reduced chance of failure and / or malfunction.

There is therefore a need for a roof device that offers a solution to one or more of the above problems.

SUMMARY The present invention and its preferred embodiments aim to provide a solution to one or more of the aforementioned drawbacks of flat roofs. To this end, the present invention relates to a roof device comprising slidable roof panels arranged movably along a rail system. The invention also relates to a sliding roof comprising the movable roof device. The invention also relates to the use of the roof device in a roof. The invention furthermore relates to a method for sliding the roof device open and closed. The roof device according to the present invention can provide an improvement with regard to the (splash) watertightness and / or water drainage, strength and / or resistance to (snow) loads, finishing options, light transmission and / or sun protection.

The invention is also in the field of devices for (open) sliding structures such as vertical sliding walls. In particular, the invention provides a wall device comprising slidable wall panels movably arranged along a rail system, as described herein. To this end, the present invention also relates to a wall device comprising slidable wall panels arranged movably along a rail system. The invention also relates to a sliding wall comprising the movable wall device. The invention also relates to the use of the wall device in a sliding wall. The invention further also relates to a method for sliding the wall device open and closed.

Unless defined otherwise, all terms disclosed in the invention, including technical and scientific terms, have the meaning as commonly understood by one of skill in the art. As further guidance, definitions are included for further explanation of terms used in the description of the invention.

One aspect of the invention relates to a device comprising a plurality of stackable panels arranged movably along a rail system. This device can be suitable for a sliding structure, such as a sliding roof or sliding wall. It will be clear that the embodiments of one structure described below are also applicable to other, similar structures; i.e. suitable or preferred embodiments of the roof device or sliding roof are also suitable or preferred embodiments of the wall device or sliding wall, and vice versa.

The invention relates to a roof device for a sliding roof.

The roof design 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 a slope of less than 10 ° and preferably less than 5 °, for example less than 2 ° or 1 °. The slope is determined by the height difference between adjacent panels; the individual panels may, for example, have a curved surface without any difference in height.

A roof device is a movable device for filling in a roof frame.

When the movable roof device is mounted in a roof, it can be referred to as a sliding roof.

The slide-open roof can form part of a construction comprising a roof structure with an opening and upright walls, such as a terrace covering, pergola, carport and the like.

Sliding open means that the roof can slide open as well as closed.

The movable device will be mounted in the roof in a manner that allows 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 one quarter open.

The invention alternatively relates to a wall device for a sliding wall.

The wall arrangement is particularly suitable for a flat sliding wall.

The sliding wall can form part of a construction comprising a wall structure with an opening and upright walls.

Sliding means that the wall can slide open as well as closed.

The movable wall device will be mounted in the wall in such a way that a movement is possible between at least two positions, namely a first, closed wall position and a second, open wall position.

Optionally, the wall device can be adapted to move to one or more intermediate positions in which the wall is only partially open, for instance half open or one quarter open.

The roof device 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 roof arrangement; it is therefore also possible to refer to a roof panel.

Typically, a panel will have a beam or block structure consisting of six substantially rectangular surfaces; namely, a top face, a bottom face (or ground face), and four side faces.

The bottom surface is preferably substantially the same size as the top surface.

The term substantially should be interpreted as having the referenced body or structure substantially approximating the referenced geometric shape;

i.e. apart from any roundings, bends, protrusions, connection elements, 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 or will be oriented towards the ground plane (the earth, eg the terrace floor) , while the top panel wall or top wall is the panel wall which is or will be oriented towards the top surface (the sky, eg the open sky).

Any reference to a direction of the panels will 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: the front panel walls or front walls are oriented (in an open roof position) towards the open roof space, while the rear panel walls or rear walls (in an open roof position) are oriented towards the roof frame in which the roof device is or can be mounted.

Thus, a panel will move forward towards its front panel wall, i.e. from an open roof position to a closed roof position, and equivalently panel will move rearwards towards its rear panel wall, i.e. from a closed roof position to an open roof position.

Reference is made to the figures and examples for further clarification.

Throughout the text, the terms -side, -wall, -side, -face can be used interchangeably; for example, top, top, top wall, top face should 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 walls can be partially or completely curved (i.e. curved surface); for example, an arcuate surface of the top panel wall can provide improved water drainage to the sides of the roof.

An equivalent definition is used for wall installations, whereby the outer space is regarded as the top surface and the interior space as the bottom surface.

A plurality of panels indicates that at least two panels are arranged movably along a rail system; the panels can move along the rail system or parts of the rail system in a direction that allows the roof to open and close.

The panels are preferably slidably arranged in the rail system; the panels can slide or slide along the rail system or parts of the rail system.

A rail system will typically include one or more guide rails that are mounted or mountable on the roof.

Examples of suitable rail systems for the current roof design are discussed further separately.

There are several ways to enable movement of panels in a rail system.

The panels may comprise moving elements which are placed in the rail system or parts of the rail system and allow movement of the panels.

An example of a suitable moving element is a roller bearing, which can roll or slide over the surface of a guide rail.

All panels can be arranged movably, but at least one panel can also be fixed in a non-movable manner.

Such a fixed panel can serve, for example, as a support, demarcation or as a coupling point.

In some embodiments, there is minimal clearance between stacked panels so that loads (e.g. snow load) are carried by all stacked panels.

This can be achieved because the top panel rests on the panels below.

When, for example, the panels interlock with roller bearings, these roller bearings can rest on an underlying profile in stacked position.

The movable panels are preferably stackable; they can be stacked one above the other.

The movable panels are stackable with a (fully) open roof position.

Preferably, the panels are stacked in alignment one above the other.

An aligned stack means that the stack shows virtually no deviations; the top and bottom top panel walls of the adjacent stacked panels will almost completely cover each other.

In the open roof position, the open roof space can hereby be limited to the area of only one panel.

This is different from other roofing arrangements where often only part of the panels can slide (e.g. where only one panel slides on a second panel), and / or the panels can only partially slide over each other (e.g. where the panels protrude on one side and form a staircase structure), which limits 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.

The stacked panels can optionally lie on top of each other; the top or bottom panel walls of top or bottom 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 individually absorbed by, for example, the rail system and / or additional support elements, or a combination of both.

The movable panels are preferably co-plane alignable; they can be aligned in the same plane.

The movable panels are aligned in the same plane with a (fully) 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 stair structure) in a straight line (no curvature).

The interface of the top and / or bottom surfaces of each panel will, in a fully closed roof position, continue into the respective top and / or bottom surfaces of the adjacent panels; i.e. apart from any protrusions (e.g. reinforcing elements) or openings (e.g. channels 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.

The movable panels are preferably seamlessly connectable to each other; they can connect seamlessly.

A seamless connection means that the top and / or bottom surfaces of adjacent panels are continuous, without gaps or interruptions between the surfaces of the adjacent panels; interruptions can possibly be filled by decorative elements or lighting (LED). In a preferred embodiment, the bottom surfaces of the panels adjoin each other seamlessly to form a continuously flat underside of the roof.

In addition to an aesthetic improvement, the current roof design can also provide an improved connection between adjacent panels.

This seamless connection ensures that there is no possibility for water or dirt to get through gaps between adjacent panels.

As a result, the current roof design can provide a completely splash-free water seal.

This is different from other panel arrangements in which the panels slide in different planes and thereby form a staircase or saw-tooth structure in which dirt or water can get trapped or leak through.

There can be numerous variations on the dimensions of the panels and, consequently, also on the dimensions of the roof arrangement.

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 can 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 can 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 can 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 example embodiment, a roof with the following dimensions is considered: 4.50 m x 6.20 m.

In a first example, this roof can be completed by 6 movable panels, each panel being 950 mm x 4200 mm (after deduction of the frame in which the illustrative roof infill will be mounted). In a second example, this same roof can be filled in by 8 panels, each panel being 715 mm x 4200 mm.

The advantages and disadvantages of the different sizes are believed to be known by those of skill in the art.

Alternatively or additionally, several roof devices can also be placed along or opposite each other in separate rows and / or columns.

As a result, there is in principle no restriction on the maximum roof surface that must be filled in.

The panels can be made from different materials or even combinations of materials. The choice of material 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 (a lot of rain or drought), and so on. By way of example, a panel can be made of metal (e.g. aluminum), plastic (e.g. PC, PMMA, PVC), (laminated) glass, textile, etc., and / or combinations of different materials. The advantages and disadvantages of the different material types are believed to be known by those skilled in the art. The panels can also be provided with lighting (LED) or decorative elements.

In one aspect, the invention relates to a sliding roof roofing device (or alternatively, a sliding wall opening wall device) comprising a plurality of stackable panels movably arranged along a rail system; wherein the movable panels can repeatably move between a first, closed (roof) position, wherein the panels are aligned next to each other in the same plane (and preferably join together seamlessly, i.e. covered and splash-proof); and, a second, open (roof) position in which the panels are stacked aligned one above the other.

An alternative aspect of the invention relates to a wall device comprising a plurality of stackable panels movably arranged along a rail system; wherein the movable panels can repeatably move between a first, closed wall position (i.e., a closed position of the wall) in which the panels lie side by side aligned in one and the same plane or are alignable and preferably connect seamlessly together, and a second, open position wall position (ie an open position of the wall) in which the panels are stacked or stackable one above the other, preferably stacked in alignment one above the other or stackable.

The rail system serves to control and limit the range of motion of the movable panels, as well as to support the panels in the roof arrangement. A typical rail system will generally comprise at least two parallel guide rails which are fixedly mounted at the same height and on opposite sides of the roof to be filled in. This allows the movable panels to be evenly supported on two sides. The guide rails can optionally consist of multiple guide rail members that communicate with each other to form a continuous guide surface. For simplicity, various embodiments of the rail system in single form will be described below, but those skilled in the art will appreciate that these embodiments will be mounted in pairs on either side of the roof frame.

The rail system may include fasteners which are used to permanently attach the parts of the rail system to the roof or a part of the roof, such as the roof framing. The fasteners can be screws or nails. Depending on the application, the confirmation can be a permanent or a temporary confirmation.

The rail system may include a control system that controls and controls the movement of the movable panels. The control system can be a manual control system, in which a user allows the panels to move directly or indirectly. Preferably, the control system is a motorized control system. A motorized drive system will typically include a motor and a drive means that converts the movement of the motor into movement of the panels. The rail system can be a single track rail system where the movable panels can move through one plane. The panels can move sequentially (1 by 1) or simultaneously (in a row) along the single-track rail system. Preferably, the movable panels will move coupled together along the single track rail system. As a result, the control of panels can be limited to control of one or a limited number of panels in the sequence of panels. The single track rail system may comprise a single guide rail extending in a direction along which the slidable roof will slide open and close; the movable panels will therefore also remain in the same plane during both the opening and closing of the roof. Reference is made to Example 1 by way of example. Preferably, the single-track rail system comprises two guide rails which are arranged parallel to each other and both extend in a direction along which the slide-open roof will slide open and close. The addition of a second guide rail can cause the front and rear of the movable panels to slide along a separate guide rail, allowing for parallel up-stacking motion which can improve movable stacking. The single-track rail system may further comprise one or more stacking rails that extend in an upward and / or diagonal direction along which the panels will stack. The stacking rails will preferably overflow in the direction of the guide rail to ensure a smooth transition. Alternatively, the guide rails may be curved in an upward and / or diagonal direction along which the panels will stack. The rail system can be a multi-track rail system in which the movable panels move through different, preferably parallel, planes to end in one and the same plane. The panels can move sequentially (1 by 1) or simultaneously (stacked or next to each other) along the multi-track rail system.

The movable panels can move independently of each other along the multi-track rail system.

However, this embodiment requires individual control of each individual movable panel.

The movable panels can also move depending on each other along the multi-track rail system, for instance by a full or partial coupling of the movable panels.

This embodiment has the advantage that only one or a limited number of movable panels have to be controlled.

Reference is made to Example 2 by way of example.

The multi-track rail system may comprise a plurality of guide rails which extend in a sideways and / or diagonal direction along which the slidable roof will slide open and close.

Preferably, the multi-track rail system includes two guide rails per movable panel, with a first guide rail supporting the front and a second guide rail supporting the rear of a panel.

This allows a fully controlled movement of each panel in relation to the rail system, reducing the risk of defects or blockage.

The first front guide rail and the second rear guide rail may differ from each other by a bend in the downward and / or diagonal direction at the end of the guide rail.

This bending will ensure that the panels can slide more smoothly in one and the same plane.

In addition, it is of course also possible to combine a single-track rail system with the multi-track rail system, for instance by moving part of the movable panels along a single-track rail system and a second part of the movable panels along a multi-track rail system.

A combination of single-track and multi-track rail systems can be interesting to realize larger roof installations.

The roof device preferably comprises a stacking system; wherein each movable panel is adapted for repeatable coupling and disconnection with one or two adjacent panels by means of the stacking system; such that when coupled, the adjacent panels are stacked one above the other.

Preferably, each panel includes an engagement element and a notch, the engagement element of each panel being adapted for repeatable placement in the notch of an adjacent panel.

The stacking system is a repeatable joining system where adjacent, preferably bottom and top, movable panels are joined together at the transition from a closed roof position, where the panels are aligned in the same plane, to an open roof position, where the panels are stacked one above the other .

The stacking system can ensure that the adjacent panels are stacked partly, preferably completely aligned, one above the other when the roof is closed.

The stacking system can also ensure that the panels are partly, preferably completely, stacked one above the other at the transition from a closed roof position to an open roof position; the panels can be stacked when the roof is slid open.

This has the advantage that the chance of incorrect or incomplete stacking of panels can be limited or completely avoided.

In addition, the stacking system can improve the compactness of the closed roof device and / or increase the size of the open roof space by means of an aligned stacking.

In a preferred embodiment, the stacking system can ensure that in closed position the panels are aligned in one plane and in open (stacked) position fall within a limited space, whereby during the transition from closed to open roof position, or vice versa, the panels do not. get out of the limited space.

For a roof device, the limited space can be an upper beam of a covering, or a wall device may be a side beam of a sliding wall.

The stacking system can be configured for coupling two panels, which are partially, preferably completely, stacked one above the other; a first panel and a second panel.

When coupling, the first panel can come to lie on top of the underlying or at the bottom of the top second panel; the coupled panels are then stacked.

Preferably, the coupled panels will be stacked completely on top of or under each other; the top and bottom surfaces of the two disconnected panels will then completely cover.

Preferably, the coupling of two panels, partially or completely stacked one above the other, is accomplished with a sideways movement of a first, top or bottom panel over a second, bottom or top panel.

Preferably, the second top or bottom panel will not be movable during the coupling.

Preferably, the coupled panels will be stacked overlapping on top of or under each other; the top and bottom surfaces of the two joined panels will then completely overlap.

When disconnected, the first panel can move adjacent to the second panel so that the first and second panels come to lie in the same plane; the disconnected panels are then arranged aligned.

Preferably, the uncoupling of panels stacked partially or completely one above the other is accomplished upon downward movement of an underlying panel relative to an overlying panel, or upon an upward movement of an overlying panel relative to an underlying panel.

In a preferred embodiment in which the roof arrangement comprises a multi-track rail system, the stacking system can further allow the coupled panels to move in a stacked manner along the multi-track rail system.

Preferably, the stacked and coupled panels move together or simultaneously along the multi-track rail system.

This has the advantage that the control of all movable panels can be limited to a control of one or a limited number of panels in the sequence of stacked panels and no additional coupling system or control system must therefore be provided.

Preferably, the control of the movable panels will be limited to a control of one topmost or bottommost movable panel which will move in front and will pull or push all coupled panels along the multi-track rail system by means of the stacking system.

This can also reduce the complexity of the roof design.

Reference is made to example 4 by way of example.

The stacking system may include an engagement element adapted for repeatable engagement and disconnection with a notch; the engaging element and the notch are repeatably connectable and detachable.

In particular, the engaging element can fit partially, preferably completely, within the notch; the placement of the engaging element in the notch is then regarded as a coupling.

Each panel of the plurality of movable panels may include such an engagement element and notch, wherein the engagement element of a first, top or bottom panel is engageable with a notch of a second, bottom or top panel.

Preferably, the notch will be in line with the engaging element.

This allows complete overlap of the two panels.

The gripping element can run over the full width of the panel.

The engaging element can then comprise a protruding spring or tongue which can be coupled to a groove or recess of the same size (for instance via a tongue-groove connection). The engaging element can also run over a limited length of the panel.

The engaging element may then comprise a protruding body or protrusion which is engageable with a cavity or opening of the same shape and size.

The engagement element may also include a combination of protruding springs or protrusions.

The engaging element has a length, height and width which preferably substantially correspond to the length, depth and width of the notch.

This allows the notch to completely encircle the guide element; the gripping element then fits completely into the notch.

The engaging element may comprise a downwardly directed body.

The engaging element can form a perpendicular angle to the bottom panel wall, or the engaging element can be at an oblique angle; the engaging element is preferably perpendicular to the bottom panel wall.

The appropriate notch is then located on the top of the panel to be connected.

Alternatively, the engaging element may comprise an upwardly directed body.

The engagement element may form a perpendicular angle to the top panel wall, or run at an oblique angle; the engagement element is preferably perpendicular to the top panel wall.

The appropriate notch is then located on the underside of the panel to be connected.

The stacking system may further include a guide member configured to guide the engagement member toward or within the notch upon lateral movement of a movable panel along the rail system. The movable panel with the engaging element will then partially move over or under the panel to be coupled with the notch and guide element. In a preferred embodiment, the stacking system includes a guide element, an engaging element and a notch.

The guide element preferably comprises a protruding body arranged on the same side of the panel as the notch. Preferably, the guide element will adjoin the notch.

The guide element can hereby be engaged by the engaging element and guide the engaging element towards or into the notch. During lateral movement of a first movable panel, the engaging element of the first panel may collide with the guiding element of a second lower or upper panel, this collision will cause the engaging element to enter the notch upon further lateral movement of the first panel.

Preferably the notch is located on the top side of the panel to be coupled and the guide element will be directed upwards. The engaging element can be perpendicular to the top panel wall, or form a perpendicular angle to a tangent line across the top surface of the panel (if the top panel wall is spherical). Alternatively, the notch can be on the underside of the panel to be coupled and the guide element will be directed downward. In a particular embodiment, the notch can be partially or completely formed by two outwardly directed elements which approximate the shape of a notch. The guide element can thereby form a side wall of the notch. This particular embodiment can ensure that the distance between the adjacent panels can be increased.

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 in no way be construed as limiting.

Example 1: Single-track rail system Fig. 1 shows a schematic representation of a roof arrangement (100) comprising three panels (200) movably arranged along a single track rail system (310). The movable panels will move in one and the same plane; preferably slidably moving.

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

FIG. 2 shows a schematic illustration of a roof device (100) comprising three panels (200) movably arranged along a single track rail system (310), the roof device (100) further comprising a connection system. The connection system includes a connection element (220) and a complementary connection point (225); each movable panel (200) adapted to couple with adjacent panels includes a downwardly facing connector (220) arranged on a front panel wall and an upwardly facing connector (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 slide-open roof will slide open and close. 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. The guide rails run at a first end in the direction of the rear panel walls

(obliquely) upwards so that the panels can be stacked one above the other. Each movable panel (200) preferably includes at least one roller bearing per guide rail (311,312): at least four roller bearings in total.

Equivalent to the example described above, in FIG. 2 (a), the movable panels (200) are stacked in alignment one above the other. FIG.2 (b} The first panel (201) will move forward along the guide rails (311, 312) of the single track rail system (310) FIG.2 (c) Due to the forward movement, the junction point (225) will be arranged on the rear panel wall of the first panel (201) overlapping with the connector (220) arranged on the front panel wall of the second panel (202) FIG.2 (d) This will allow the second panel (202) to move downward. (e) The downward movement of the second panel (202) will cause the second to lie in the same plane as the first panel (201) and the two panels (201,202) will couple together by hooking the connector (220) of the second panel (202) to junction (225) of the first panel (201) This coupling (circled) will ensure that upon further forward movement of the first panel (201), the first panel (201) second, coupled, panel (202) will be able to pull into itself the forward direction of movement. FIG. 2 (f) 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).

FIG. 3 shows a detailed view of a first movable panel (201) including a connection system. The connection system includes a connection element (220) arranged on a front panel wall of the panel (201) that can couple with a complementary connection point arranged on a rear panel wall of another panel (not shown). The connector (220) includes a downwardly directed hook-shaped body extending forward from the front panel wall; the hook-shaped body has an L-shaped profile with a downwardly directed hook structure. The junction system further includes a junction (225) disposed on a rear panel wall of the panel (201) that can mate with a complementary junction element disposed on a front panel wall of another panel (not shown). The junction (225) includes an upwardly directed hook-shaped body that extends 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 a rail.

FIG. 4 shows a detailed view 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) by the connection element (220) of the first panel (201) hooking into the complementary junction (225) of the second panel (202) . In this exemplary embodiment, there are no gaps between the two adjacent panel walls of the two joined panels (201, 202). A seamless connection is obtained; both the top surface and the bottom surface of the joined panels form a substantially continuous and contiguous surface.

Example 2: Multi-track rail system Fig. 5 and 6 show schematic illustrations of two embodiments of roofing devices comprising three panels (200) movably arranged along a multi-track rail system (320). The panels (200) will be able to move in different but parallel planes.

FIG. 5 illustrates a first embodiment where the movable panels will move stacked one above the other through the rail system.

FIG. 5 (a) In a first, open roof position, all movable panels (200) are stacked one above the other.

The bottommost panel (210) is attached; it cannot move along the rail system (320). FIG. 5 (b) The first movable top panel (201) will be actuated to move in the forward direction along the first, uppermost part (321) of the multi-track rail system (320); this forward direction of movement is indicated by a dashed arrow.

Forward movement of the first panel (201) can cause the underlying movable panels (202, 203) to move in the same forward direction; for example, these underlying movable panels can be pulled along by the first panel (201). Alternatively, the underlying movable panels (202, 203) can each be individually controlled.

FIG. 5 (c) Due to the forward movement, the third movable bottom panel (203) will no longer be stacked above the attached panel (210) and will be able to move downward; this downward movement direction is indicated by a dashed arrow.

FIG. 5 (d) The downward movement will cause the third movable panel (203) to land in the same plane as the attached panel (210) so that the panels are aligned next to each other.

FIG. 5 (e) The remaining movable panels will move forward until movable all panels (200) are aligned next to each other in one and the same plane (and preferably join together seamlessly). FIG. 6 illustrates a second embodiment where the movable panels will move separately through the rail system.

FIG.6 (a) is equivalent to FIG.5 (a), except that each movable panel (200) will be driven separately.

In FIG. 6 (b), by way of example, the third movable bottom panel (203) will be actuated first to move forward along the multi-track rail system (310). FIG. 6 (c) The third movable bottom panel (203) will move forward until it is no longer stacked above the attached panel (210) and will be able to move downward; this downward movement direction is indicated by a dashed arrow. FIG. 6 (d) The downward movement of the third panel (203) will cause the third panel (203) to land in the same plane as the attached panel (210) will. 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. FIG. 6 (d) Each remaining movable panel will advance individually until all movable panels (200) are next to each other in one and the same plane (and preferably connect seamlessly).

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

The connection system includes a connection element (220) and a complementary connection point (225); each movable panel (200) adapted to couple with adjacent panels includes a downwardly facing connector (220) arranged on a front panel wall and an upwardly facing connector (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 slidable roof will slide open and close. 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, so at least four roller bearings in total. The bottommost panel (210) is attached; it cannot move along the rail system (320). The first panel (201) is supported by a first front (331) and first rear guide rail (341), the second panel (202) by a second front (332) and second rear guide rail (342), and the third panel (203) through a third front (333) and a third rear guide rail (343). The front guide rails (331-333) are laterally oriented guide rails that merge into a diagonal orientation. The rear guide rails (341-343) are diagonally oriented guide rails that transition into a downward orientation.

Equivalent to the example described above, in FIG. 7 (a), the movable panels (200) are fully stacked one above the other.

FIG. 7 (b) The third movable, bottom, panel (203) will, by way of example, be the first to move forward along the guide rails (333,343) of the multi-track rail system (320). FIG. 7 (c) The third panel (203) will continue to move forward until the connector (220) arranged on the rear panel wall of the third panel (203) will overlap with the connector (225) arranged on the front panel wall of the fastened panel (210). FIG. 7 (d) This will allow the third panel (203) to move downward so that the connector (220) of the third panel (203) will mate with the connector (225) of the attached panel (210). The third panel (203) will be flush with the attached panel (210).

FIG. 7 (e) Next, the second movable panel (202) will also move forward along the guide rails (332,342) of the multi-track rail system (320) until the second panel (202) can similarly engage with the third panel (203) ); namely, by coupling the connector (220) of the second panel (202) to the connector (225) of the third panel (203). FIG. 7 (f) The remaining panels will in turn also move forward until all movable panels are aligned next to each other in one and the same plane (and preferably connect seamlessly). 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.

FIG. 8A and 8B show schematic illustrations of two embodiments of roof devices (100) depicting an interconnection between two adjacent panels (201, 202), wherein the connector (220) of the first panel (201) engages with the complementary connector (225) of the second panel (202). The junction (225) includes a first body that extends 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 facing second body runs diagonally towards the front panel wall of the second panel at a low angle of inclination.

The end of the second body is bent 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 connector (220) includes a first body that extends laterally rearwardly from the rear panel wall of the first panel (201). At right angles to the end of the first body is a downward directed second body.

The downwardly directed second body is partially curved to form a stepped surface having a structure that matches the surface of the complementary junction (225). The end of the second body is bent 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 with a downward movement of the first panel (201) on the second panel (202), the connection element (220) will be able to hook onto the connection point (225) to connect the two joined panels (201, 202). . The first panel (201) further includes a reinforcing element (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 connecting element (220); especially with a first portion of the connector member body (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). Due to the coupling between the connection element (220) of the first panel (201) and the connection point (225) of the second panel (202), the stiffening element (290) will be able to support the second panel (202) and load on the top surface of the roof equipment can be spread over the plurality of coupled panels.

FIG. In particular, 8A shows a first embodiment where a slide-on clip (230) has been placed on one end of the connector (220).

In this embodiment, the connector (220) will be slidably engageable with the connector (225). This clip (230) will come into contact with one end of the junction (225) of the second panel (202) during engagement, allowing the body of the junction (225) to slide over the clip (230).

The clip (230) will limit the friction between the bodies of the connector (220) and the connector (225) and thereby improve coupling / disconnection.

FIG. In particular, 8B shows a second embodiment in which a roller bearing (235) is mounted on one end of the connecting element (220).

In this embodiment, the connection element (220) will be able to rollably engage the connection point (225). This roller bearing (235) will come into contact with one end of the junction (225) of the second panel (202) during engagement, allowing the body of the junction (225) to roll over the roller bearing (235).

The roller bearing (235) will prevent friction between the bodies of the connector (220) and the connector (225) and thereby improve coupling / disconnection.

FIG. 9A and 9B show images of the first embodiment of FIG. 8A (with sliding clip) in perspective. In addition to the features and components described above, Figs. 9A and 9B illustrate the extent of the openings formed between the rear panel wall of the first panel (201) on the one hand and the front panel wall of the first panel (201) on the other hand when coupling the terminal (225) to the terminal element (220). The size and shape of the opening can be adjusted by changing the shape of the terminal (225) and / or the terminal (220), and / or by the presence of additional panel walls and / or protruding structures.

FIG. 9A shows an upper perspective where on the top surface the upward opening opening forms a gutter (221) between the front panel wall of the second panel (202) and the connector (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).

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

FIG. 10 shows a schematic view of the above-described connection system according to the second embodiment of FIG. 8B (with roller bearing). FIG. 10 (a) shows an uncoupled position in which a terminal (220) of a first, upper, panel (201) lands on top of a terminal (225) of second, lower, panel (202). This position can be established by way of example by a multi-track rail system as described in example 2. In FIG. (B) on downward movement of the first panel (201), the roller bearing (235) mounted on one end of the connector (220) will come into contact with one end of the connector (225). FIG. (C) 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. FIG. {D) The rollable coupling between the connection element (220) and the connection point (225) here forms an upwardly directed gutter (221) and a downwardly directed interspace (226).

FIG. 11 and 12 show a schematic illustration of the above-described connection system used in a roof arrangement comprising a multi-track rail system (310). FIG. 11A shows an open roof position where the movable panels are stacked one above the other.

In the open roof position, the reinforcement 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.

FIG. 11B shows a closed roof position in which the movable panels are aligned side by side in one and the same plane.

The reinforcement elements (290) of the front panels can improve the strength 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 attached (non-movable) panel (210) will also include a stiffener (290).

The reinforcement elements (290) of the plurality of movable panels (200) will form a rib structure on the top surface of the roof which can improve the rigidity of the roof over its entire surface.

FIG. 12A shows a further embodiment of the roof device of FIG. 11A, wherein the first, top panel (201) includes a second reinforcement element (295) arranged on a front panel wall.

The presence of a reinforcement element (290) at each end of the roof can further enhance the strength of the roof over its entire surface.

FIG. 12B shows a detailed view of the stacked panels of FIG. 12A.

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.

Example 4 further describes a preferred embodiment of the stacking system.

FIG. 13 shows a detailed view of a first movable panel (201) including a stacking system.

The stacking system includes a downwardly directed engagement element (250) disposed on a bottom panel wall of the panel (201) that fits into a compatible notch (245) disposed on a top panel wall of an adjacent panel (not shown).

The depth and width of the notch (245) substantially corresponds to the length and width of the downwardly facing engagement element (250) so that the notch (245) can completely enclose the engagement element (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) disposed on an upper panel wall of the panel (201) which is abutted against a downwardly directed projection (250) disposed on a lower panel wall of an adjacent panel (not shown).

FIG. 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.

FIG. 14 shows an embodiment of the stacking system in which the movable panels move from an open roof position to a closed roof position.

FIG. 15 shows an embodiment of the stacking system in which the movable panels move from a closed roof position to an open roof position.

In FIG. 14 (a) shows that two movable panels (201, 202) stacked on top, move forward (i.e., toward the front panel wall) on 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 linked together by means of the stacking system (circled): the downwardly facing protrusion (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 movement direction of the first panel (201). FIG. 14 (b) The second panel (202) is movable forward until a front of the second panel (202) contacts one end of the second front guide rail (332); this end will cause the forward movement of the second panel (202) to be blocked (flat arrow). FIG. 14 (c) However, the rear of the second panel (202) will be able to move further downward along a downwardly directed end of the second rear guide rail (342). This downward movement of the second panel (202) can cause the coupling between the downwardly facing projection (250) of the first panel (201) and the notch (245) of the second panel (202) to disengage.

FIG. 14 (d) The disconnection will allow the first panel (201) to move forward unimpeded again along the guide rails (321, 331). In FIG. 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) is a second movable panel (202); for example, this second panel (202) can be flush with a closed roof position.

FIG. 15 (b) The first panel (201) will be able to move backward unimpeded until the downward facing protrusion (250) of the first panel (201) contacts the upwardly facing protrusion (240) of the second panel (202) . FIG. 15 (c) This contact will allow the first panel (201) to push the second panel (202) forward on further rearward movement of the first panel (201). A rearward movement of the second panel (202) will first cause the second panel (202) to move upwardly along a downwardly directed 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 completely enclose the downwardly facing projection (250) of the first panel (201).

The two adjacent panels (201, 202) are linked together by means of the stacking system (circled). FIG. 15 (d) The two coupled panels (201,202) can then move together, preferably aligned, stacked one above the other, backward on separate guide rails of the multi-track rail system (320).
