Description

LAMELLAR ROOF

The present invention relates to a slat roof, comprising several slats arranged parallel to each other and arranged so as to be rotatable about respective rotation axes, between an open position, in which an intermediate space extends between the slats, and a closed position, in which the slats together form a closed cover, wherein each slat, on a first longitudinal side, comprises a slat gutter which slants towards an exit opening which is provided in an end of the corresponding slat and wherein the slat roof comprises a lateral gutter which extends essentially perpendicular to the slats under the respective exit openings of the slats, and which, facing away from the slats, comprises an upright outer side wall which extends at least partly next to the slats.

Such slat roofs with rotatable slats are generally used to protect an external space, such as terrace covering or veranda roof, etc. In addition to the abovementioned slats, such a slat roof may also comprise one or more additional slats. In the remainder of this patent application, only the former will be referred to. In their closed position, the slats form a watertight roof. By rotating the slats between their closed position and their open position, it is possible to regulate the incidence of light and the ventilation for the space underneath the slats. By directing the slats, it is possible to protect against the sun and/or wind or, on the contrary, to allow them in.

Precipitation which, in the closed position of the slats, falls onto the slats, is drained off substantially towards the lateral gutter via the slat gutters and is subsequently drained off the slat roof via a drainage gutter or via a front gutter which may be provided at the front of the slat roof. If desired, a part of this precipitation may also be drained off via a lateral gutter which is arranged on the side of the slats opposite the side of the former lateral gutter. In the remainder of this patent application, only the former lateral gutter will be referred to. In order to enable the slats to rotate above the lateral gutter, they always have to be arranged at a certain distance with respect to this lateral gutter. In order to enable the slats to rotate and still be able to drain off sufficient precipitation water, the lateral gutter in practice comprises, on one side, an inner side wall which is arranged underneath the slats and at a certain distance from the slats and, on the other side, an outer side wall which, facing away from the slats, extends at least partly next to the slats. The outer side wall is made sufficiently high to enable it to catch precipitation water which flows out of the exit openings with a certain force by means of said outer side wall. However, in practice, the inner side wall cannot be made sufficiently high to ensure that precipitation water is kept inside the lateral gutter in all circumstances, since it would otherwise hamper the rotation of the slats. In practice, precipitation water which flows from the slat gutters into the lateral gutter often spills over the inner side walls and thus ends up in the space underneath the slat roof.

Several solutions have already been proposed to limit the amount of precipitation water entering the inner space in this way.

FR 2 676 079 Al described a variant of a slat roof in which the lateral gutter is vertically displaceable and the displacement of the movement is coupled to the rotation of the slats, so that drainage of the slats can be effected at a minimal height above the lateral gutter. This offers a partial solution against water from the lateral gutter spilling over the inner side wall, but only moves the drainage problem from the lateral gutter to a drainpipe or towards a front gutter of the slat roof.

In EP 1 127 992, the slats are laterally provided with plate parts which extend between the slats and the lateral gutter. These plate parts are provided in order to hide the movement mechanism for rotating the slats from view. DE 20 2004 016 025 Ul describes that these plate parts can also detain water which splashes up in the lateral gutter. However, in practice it is found that such plate parts cannot detain splashing water to a sufficient degree. The reason for this is that precipitation which splashes up in the lateral gutter is able to pass between the gutter edge of the lateral gutter and these plate parts and thus still reach the space which is covered by the slat roof. FR 2 701 977 Al describes a solution which is intended for a slat roof in which the slats rotate about an axle which is arranged on a longitudinal side of the slat. A sealing is fitted at the top of the inner side wall of the lateral gutter, just below the respective ends of the slats. Upon rotation on this side, the slats always extend at the same height with respect to the lateral gutter, in which case said sealing prevents the ingress of water as much as possible. However, this solution is not suitable for slat roofs in which the axle of the slats is not arranged on a longitudinal side of the slat. The slat roof from DE 34 12 770 Al also has a sealing of this type fitted at the top of the inner side wall of the lateral gutter, but the axle of the slats is not arranged on a longitudinal side of the slat. In this case, the sealing is only operative in the closed position of the slats. In order to be able to rotate the slats, the part of the inner side wall which is provided with this sealing has to be moved to beyond the ends of the slats. At that point in time, upon rotation of the slats, any residual water which is still present on the slats will fall unhindered into the space which is covered by the slat roof.

It is an object of the present invention to provide a slat roof according to the introductory part of the first claim, in which the watertightness is further improved at the location where the slats drain off into the lateral gutter and for any slat roof, regardless of where the axle of the slats is situated.

This object of the invention is achieved by providing a slat roof, comprising several slats arranged parallel to each other and arranged so as to be rotatable about respective rotation axes, between an open position, in which an intermediate space extends between the slats, and a closed position, in which the slats together form a closed cover, wherein each slat, on a first longitudinal side, comprises a slat gutter which slants towards an exit opening which is provided in an end of the corresponding slat and wherein the slat roof comprises a lateral gutter which extends essentially perpendicular to the slats under the respective exit openings of the slats, and which, facing away from the slats, comprises an upright outer side wall which extends at least partly next to the slats and wherein the slat roof comprises one or more sealings which are arranged between the slats and the upright outer side wall of the lateral gutter, in such a manner that these, viewed in the closed position of the slats, extend at least under the exit opening of each slat and extend from each slat up to a location adjacent to said upright outer side wall of the lateral gutter.

By draining off the water by means of such a sealing to the outer side wall of the lateral gutter, which is turned away from the slats, this water will stick to this outer side wall due to the adhesive force thereof and trickle downwards along this outer side wall into the lateral gutter. The risk of water splashing up in the lateral gutter is consequently greatly reduced.

The abovementioned sealing may, for example, be made from a flexible material, such as for example flexible plastic or rubber etc., or may also be, for example, a brush sealing.

A first specific embodiment of a slat roof according to the present invention comprises one such sealing per slat, which sealing is fastened to the corresponding slat in such a way that it extends at least under the exit opening of the corresponding slat and extends from the slat to a location adjacent to said upright outer side wall of the lateral gutter.

In a second specific embodiment of a slat roof according to the present invention, said one or more sealings are fastened to the upright outer side wall of the lateral gutter and are provided with passage openings next to this upright outer side wall. Water which is diverted towards the outer side wall of the lateral gutter by means of such a sealing will flow along this outer side wall and downwards into the lateral gutter via the passage openings. More specifically, one such sealing may in this case be provided which extends along the length of the lateral gutter. In a preferred embodiment of a slat roof according to the present invention, the sealing comprises at least a part which is made from flexible material, so that this sealing, when it is fastened to a slat, will always adjoin the upright outer side wall sufficiently well and, when it is fitted to the outer side wall, will always adjoin the slats sufficiently well, while hampering rotation of the slats as little as possible.

This flexible part of each sealing of such an embodiment preferably extends along essentially the entire length of this sealing.

Furthermore, each sealing of such an embodiment preferably comprises a first part made of less flexible material, adjacent to the flexible part and adjacent to its end which is facing away from the location where this sealing is fastened. If such a sealing is fastened to a slat, said first part made of less flexible material will be situated adjacent to the upright outer side wall. If such a sealing is fastened to the upright outer side wall, said first part made of less flexible material will be situated adjacent to the slats.

By providing a less flexible part between the flexible part and the end of the sealing, away from the location where it is fastened, the sealing, due to the flexible part, will always sufficiently adjoin the upright outer wall sufficiently well, when it is fastened to a slat, or adjoin the slats, when it is fastened to the upright outer side wall. Due to the less flexible part which has a lower coefficient of friction than the flexible part less friction occurs between the sealing and the outer side wall of the slats, respectively, than would be the case if the sealing were made completely out of flexible material of the flexible part. As a result, drainage of water is ensured for a longer period of time, as will be discussed in more detail with reference to the drawings.

Still more preferably, the flexible part is arranged between the first less flexible part and a second less flexible part in such an embodiment, with the second less flexible part adjoining the location where this sealing is fastened.

By means of such a less flexible part, the sealing can be fastened in a simpler and longer-lasting manner to the slat or the upright outer side wall, respectively. Such an embodiment with a second less flexible part prevents the sealing from turning over when the slats are repeatedly being rotated for a prolonged period of time.

Such less flexible parts preferably each extend along essentially the entire length of this sealing.

A sealing of this type which comprises a flexible part between two less flexible parts, is preferably made by means of co-extrusion. Furthermore, such a sealing is preferably made of a material which has a satisfactory resistance to UV and other weather conditions. Specifically, each said sealing of a slat roof according to the present invention may, for example, be made substantially from PVC. In a specific embodiment of a slat roof according to the present invention, wherein one said sealing is fastened to each slat, each slat is provided with an undercut groove at its end, under the exit opening, and each sealing comprises a foot which engages with this undercut groove. In this way, the sealing can be configured so as to be readily detachably fastenable to the slat, so that the sealing, being a component of the slat roof which is relatively more susceptible to wear, can be replaced in a simple manner.

In a specific embodiment of a slat roof according to the present invention, in which said one or more sealings are fastened to the upright outer side wall of the lateral gutter, this upright outer side wall comprises an undercut groove for this purpose and the one or more sealings comprise a foot for this purpose, which foot engages with this undercut groove. In this way, the one or more sealings can be configured so as to be readily detachably fastenable to the upright outer side wall, so that each sealing, being a component of the slat roof which is relatively more susceptible to wear, can be replaced in a simple manner. In a particular embodiment, each sealing, next to the end facing away from the location where this sealing is fastened, is configured to be rounded. When this sealing is fastened to a slat, it will therefore not leave any traces behind on the upright outer side wall and/or does not cause any scratches in this upright outer side wall. When this sealing is fastened to the upright outer side wall, it will therefore not leave any traces behind on the slats and/or does not cause any scratches on the slats. More specifically, each sealing may to this end comprise, for example, a thickened edge, adjacent to its end facing away from the location where this sealing is fastened. Furthermore, at least a part of each sealing, next to its end facing away from the location where the sealing is fastened, is preferably made from a material having a low coefficient of friction. More specifically, this part may be made, for example, from polytetrafluoroethylene (PTFE). When said thickened edge is made from PTFE next to the end of the sealing facing away from the location where it is fastened, it will leave few traces behind on the outer side wall or the slats, respectively.

Each of said sealings preferably slants away from the slats towards the upright outer side wall. In a particular embodiment of a slat roof according to the present invention, each slat, at its end which is provided with the exit opening, is provided at the bottom with a nose which hangs down towards the bottom.

A nose of this type which hangs down towards the bottom (drooping nose) forces precipitation which would, for example as a result of tilting the slats, land on the side of the slat underneath said sealing, to drip into the lateral gutter. As a result thereof, this precipitation can no longer flow back onto the underside of the slat on account of adhesion forces and thus drip into the space underneath the slat roof.

In a particularly preferred embodiment, the height of the drooping nose is chosen such that the sealing is essentially completely invisible if one is located underneath the slat roof. More specifically, each slat of a slat roof according to the present invention will be provided at said end with a head end, in which the corresponding exit opening is provided.

With such an embodiment, the slats can then be produced substantially as hollow profiles which can be sawn to length and are closed off at both sides by a head end. More specifically, each such head end can then be configured to be wedge-shaped, in which case it is configured to decrease from its one longitudinal side towards its other longitudinal side, so that the thickness of these head ends tapers. Due to the tapering of the head ends, the slats can be sawn off straight and one end of a first head end may overlap the other end of a second adjoining head end in the closed position of the slats. In the case of a tilting movement, adjacent head ends do not obstruct one another. This prevents the incidence of light or an opening from occurring at the location where the head ends overlap. In such an embodiment, the height of the sealing preferably runs at a corresponding oblique angle to the angle of the end piece, but in such a way that at the location where the thickness of the end piece is greatest, the height of the sealing is lowest and vice versa. In this way, the edge of the sealing which is adjacent to the outer side wall will run essentially parallel to this outer side wall. This contributes to a lower friction during a tilting movement of the slat and ensures an aesthetically pleasing result.

On the other hand, the same result can be achieved by sawing the slats at an angle and by not varying the thickness of the head ends.

Furthermore, the slat gutter of each slat of a slat roof according to the present invention is preferably delimited by an upright edge at an adjacent side of the slat. An upright edge of this type is intended to keep precipitation which has remained behind in the slat gutter of a slat during tilting of this slat in the slat gutter of the slat for such a length of time until the slat has been tilted so far that the distance between the slat gutter and the lateral gutter is so small, that precipitation water can no longer splash into the space underneath the slat roof. With an embodiment of a slat roof according to the present invention, in which each slat is provided with a head end at said end and in which the slat gutter of each slat is delimited by an upright edge at an adjacent side of the slat, the head end of each slat is preferably configured to be less high than the upright edge, next to the exit opening and next to the upright edge facing away from the slat. With such an embodiment, precipitation which remains behind in the slat gutter during tilting of the slat can be passed from the exit opening above the head end next to the upright edge into the lateral gutter. The present invention will now be explained in more detail by means of the following detailed description of some preferred embodiments of a slat roof according to the present invention. The sole aim of this description is to give illustrative examples and to indicate further advantages and particulars of this slat roof, and can therefore by no means be interpreted as a limitation of the area of application of the invention or of the patent rights defined in the claims.

Figure 22 shows a part of the fifth embodiment of a slat roof according to the present invention, in which the slats are in their closed position, at the location of the lateral gutter, cut in the longitudinal direction of the slats, for one of the slats thereof;

Figure 23 shows a part of Figure 22 at the location of the sealing in more detail. The slats (1) of the illustrated embodiments of slat roofs (14) according to the present invention are arranged parallel to each other in a frame. This frame is composed of beams (13) and may be attached to an external wall and/or be mounted on columns (15), as is illustrated in Figure 4.

The slats (1) are in each case arranged so as to be rotatable about a respective rotation axle (2), in which they can rotate simultaneously between a closed position, as illustrated in Figures 1, 3, 5-9, 16-19 and 21-23, and an open position, as illustrated in Figures 10-15 and 20.

In the first three embodiments and the fifth embodiment, as illustrated in Figures 1-3, 5-18 and 21-22, the slats are rotatable through an angle of 170° between their closed position and their maximum open position. This maximum position is illustrated in Figures 10-12.

In the fourth embodiment, as illustrated in Figures 19-20, the slats are rotatable through an angle of 90° between their closed position and their maximum open position.

Obviously, it is possible to work out alternative embodiments, in which the slats are arranged so as to be rotatable through a different angle.

In the open position, light and air can flow between the slats (1) to the space situated underneath. In the closed position, the slats (1) together form a closed cover.

At a first longitudinal side, each slat (1) comprises a slat gutter (3) (see Figures 3 and 21) which slants towards an exit opening (4) (see Figures 19 and 20) which is provided in an end of this slat (1). In order to enable water from precipitation which falls onto the slats (1) to be drained off quickly, the upper surface of each slat (1), viewed in the closed position of the slats (1), is configured to slant slightly towards the slat gutter (3), so that any precipitation which falls onto them is drained off towards the slat gutter (3). In one of the side beams (13) of the frame in which the slats (1) are accommodated and which extends perpendicular to the slats (1) underneath the respective exit openings (4), a lateral gutter (5) is provided (see Figures 1, 5, 6 and 22) via which the precipitation (12) is drained off further. Underneath the slats (1), the upright inner side wall (5b) of this lateral gutter (5) extends up to a certain distance from the slats (1), so that the slats (1) can rotate freely alongside this lateral gutter (5). Next to the slats (1), the upright outer side wall (5a) extends as far as just beyond the slats (1), viewed in the closed position thereof, so that precipitation water (12) which flows out of the slat gutters (3) remains in the lateral gutter (5). The rotation axes (2) of the slats (1) are fastened through this outer side wall (5a). Together with the bottom (5c), the upright inner side wall (5b) and the upright outer side wall (5a) form a substantially U-shaped lateral gutter (5).

The slats (1) are furthermore also arranged so as to be obliquely slanting towards the lateral gutter (5), so that any precipitation can flow from the slat gutters (3) into the lateral gutter (5) via the exit openings (4).

In the first four embodiments, each slat (1) is provided with a sealing (6) underneath its exit opening (4), which sealing (6) extends from the slat (1) to a location next to the upright outer side wall (5a) of the lateral gutter (5). This sealing (6) slants downwards from the corresponding slat (1) towards the upright outer side wall (5a). As a result thereof, precipitation which flows out of the exit openings (4) is drained towards the upright outer side wall (5a). As a result of adhesion, this precipitation then flows to the bottom (5c) of the lateral gutter (5) via this outer side wall (5a).

In the first embodiment, this sealing (6) is configured as a plastic profiled section which comprises a flexible profile part (6b) which extends between two less flexible profile parts (6a, 6c). The first less flexible part (6a) adjoins the outer side wall (5a). The second less flexible part (6c) is fastened to the slat (1). To this end, this second less flexible part (6c) comprises a foot (6e) and a profiled section in which an undercut groove (7) is provided is fastened to the slat (1). The foot (6e) engages with the undercut groove (7) behind the flange (7a) in order to fasten the sealing (6) to the slat (1). A sealing (6) of this type may, for example, be made from PVC by means of coextrusion. Here, the flexible part (6b) is made thinner than the less flexible parts (6a, 6c) in order to provide increased flexibility. Next to the outer side wall (5a), the first less flexible part (6a) comprises a thickened edge (6d) which may be made, for example, from polytetrafluoroethylene. This sealing profile (6) is arranged across the entire width of the slat (1).

Due to the flexible part (6b), the sealing (6) always adjoins the upright outer side wall (5a) sufficiently well.

Due to the first less flexible part (6a), the sealing (6) next to the outer side wall (5a) has a lower coefficient of friction, so that the sealing (6) causes as little obstruction as possible during rotation of the slats (1). Due to the thickened edge (6d) of this first less flexible part (6a) which is made from PTFE, the sealing (6) leaves few traces on the upright outer side wall (5a) when the slats (1) rotate.

Due to the second less flexible part (6c), the sealing (6) can be fastened in the undercut groove (7) in a releasable manner, while still ensuring a good long-term fastening.

In the second embodiment, the sealing (6) is configured as a brush.

In the third embodiment, the sealing (6) is configured as a rubber flap.

In the fourth embodiment, the sealing (6) is not illustrated.

With the second and third embodiments, the brush (6) and the rubber flap (6), respectively, are also provided with a foot which is fastened in an undercut groove in a profile at the end of the corresponding slat (1) underneath the exit opening (4). Both such a brush (6) and such a rubber flap (6) form a flexible sealing (6) between the slat (1) and the upright outer side wall (5 a) which ensures that the sealing (6) always adjoins the outer side wall (5a).

The sealings (6) in each of these illustrated embodiments ensure reliable drainage of precipitation water (12) towards the outer side wall (5a).

For longer-term usage, however, the first embodiment is preferred, as is clear from the comparative Figures 7-18. A sufficiently flexible brush (6) (see in each case the figures on the left) can be chosen, thus ensuring that it adjoins the outer side wall (5a) sufficiently well, without excessively impeding the rotation movement of the slats (1). However, after repeated opening and closing of the slats (1), it will inevitably turn over, so that it no longer adjoins the outer side wall (5a) in a downwardly slanting manner, as a result of which the precipitation (12) is no longer readily drained.

A rubber flap (6) (see in each case the central figures) may also be made sufficiently flexible (thinner) in order to efficiently adjoin the outer side wall (5a). However, the thinner it is made, the sooner it will similarly turn over during its service life and end up adjoining the outer side wall (5a) in an upwardly slanting manner. The thicker it is made, the more friction occurs during rotation of the slats (1).

The sealing (6) which comprises a flexible part (6b) between two less flexible parts (6a, 6c) (see in each case the figures on the right) will not turn over in this manner. In the fifth embodiment, a sealing (6) is fastened to the upright outer side wall (5a) and extends from this upright outer side wall (5a) to a location next to the slats (1). In this case, this sealing (6) slants downwards from the slats (1) towards the upright outer side wall (5a). In the sealing (6), next to the upright outer side wall (5a), perforations (6f) are provided via which precipitation coming from the exit openings (4) flows and is drained off towards the outer side wall (5a) via the sealing (6), and can flow through these perforations (6f). Due to adhesion, this precipitation then flows to the bottom (5c) of the lateral gutter (5) via this outer side wall (5a).

The illustrated sealing (6) from the fifth embodiment is configured as a plastic profile which comprises a flexible profile part (6b) which extends between two less flexible profile parts (6a, 6c). The first less flexible part (6a) adjoins the slats (1). The second less flexible part (6c) is fastened to the outer side wall (5a). To this end, this second less flexible part (6c) comprises a foot (6e) and an undercut groove (7a) is provided in the outer side wall (5a). The foot (6e) engages with the undercut groove (7) behind the flange (7a) in order to fasten the sealing (6) to the upright outer side wall (5a). A sealing (6) of this type may, for example, be made from PVC by means of coextrusion. Here, the flexible part (6b) is made thinner than the less flexible parts (6a, 6c) in order to provide increased flexibility. The perforations (6f) are provided in this flexible part (6b). Next to the slats (1), the first less flexible part (6a) comprises a thickened edge (6d) which is made, for example, from polytetrafluoroethylene. This sealing profile (6) is fastened essentially along the entire length of the outer side wall (5a).

Due to the flexible part (6b), the sealing (6) always adjoins the slats (1) sufficiently well.

Due to the first less flexible part (6a), the sealing (6) next to the slats (1) has a lower coefficient of friction, so that the sealing (6) hampers rotation of the slats (1) as little as possible. Due to the thickened edge (6d) of this first less flexible part (6a) which is made of PTFE, the sealing (6) does not scratch these slats (1) when the slats (1) rotate. Due to the second less flexible part (6c), the sealing (6) may be fastened in the undercut groove (7) in a releasable manner, while still ensuring a good long-term fastening.

Alternatively, instead of the plastic sealing described above, the fifth embodiment could be provided with a brush or a rubber flap which is fastened to the upright outer side wall (5 a). This brush or rubber flap is then analogously provided with perforations next to this upright outer side wall (5a). In order to be able to make the slats (1) sufficiently strong using as little material as possible, they are substantially made in the form of hollow profiles. Such slats (1) may be made from, for example, aluminium, for example by means of extrusion. The end of these profiles is in this case closed off by a head end (9), as can be seen in the fourth embodiment in Figures 19 and 20. The exit opening (4) of the corresponding slat (1) is provided in this head end (9).

Each slat gutter (3) is delimited by an upright edge (10) of the slat (1) at an adjacent side of the slat (1), as can be seen in Figures 3 and 19 and 20.

Due to such an upright edge (10), precipitation (12) which has remained behind in the slat gutter (3) of a slat (1) will still be able to flow along this upright edge (10) into the lateral gutter (5) when this slat (1) is tilted, without this precipitation (12) falling from the slat (1) into the space underneath the slats (1). This upright edge (10) also keeps this precipitation in the slat gutter (3) until the slat (1) has been tilted so far that the distance between the slat gutter (3) and the lateral gutter (5) is so small, that this precipitation water (12), without a further sealing between the slat (1) and the upright outer side wall (5a), can no longer splash into the space underneath the slat roof.

Next to the exit opening (4) and next to the upright edge (10), each head end (9) facing away from the slat (1) is configured to be less high (1 1) than the upright edge (10), as can be seen in Figure 21. In this way, precipitation water (12) which remains behind in the slat gutter (3) when the slat (1) is tilted, is passed from the exit opening (4) above the head end (9, 1 1) next to the upright edge (10) into the lateral gutter (5), as can be seen in Figure 21. Finally, each slat (1) from the first three embodiments and the fifth embodiment is provided, at its end underneath the sealing (6), with a nose (8) which hangs down towards the bottom and which is formed by the profile in which the sealing (6) is arranged (see Figures 1, 5, 6 and 22).

A nose (8) of this type which hangs down towards the bottom (drooping nose) forces precipitation (12) which would, for example as a result of tilting the slats (1), land on the side of the slat (1) underneath said sealing (6), to drip into the lateral gutter (5). As a result thereof, this precipitation (12) can no longer flow back onto the underside of the slat (1) on account of adhesion forces and thus drip into the space underneath the slat roof.

A nose (8) of this type which hangs down does not necessarily have to form part of said profile, but may, for example, also be provided as a separate component. In this case, it may also hang down further from said profile towards the bottom, for example.
