Slatted roof with rainwater drainage via the slats

Description

[0001] The invention relates to a roofing with at least two supports, on which several slats are each pivotably mounted about a rotational axis, wherein the rotational axes of the slats run from one support to the other support, wherein the longitudinal extent of the slats is limited parallel to their rotational axis by the lateral ends of the slats, wherein the slats can be pivoted by means of a drive from a closed position, in which the slats form a closed roof surface, into any desired open position, so that some of the slats are pivoted downwards out of the closed position and other parts of the slats are pivoted upwards out of the closed position, wherein the part of the slats which pivots downwards from the closed position of the slats when pivoting the slats in the direction of rotation to the open position each has a drainage channel,wherein the drainage channel has a gradient in the direction of a lateral end of the slat or that the drainage channel has two gradient sections, in particular starting from the center of the slat, each in the direction of a lateral end of the slat.

[0002] Such a roofing system is known from EP 3 663 480 A1 and WO 2014 / 136095 A1. The disadvantage is that rainwater can collect in the drainage channels of the slats, which, when the slats pivot, drip into the area beneath the roof. CA 3 018 302 A1 discloses a slatted roof in which the slats are curved rather than straight. This is advantageous for draining rainwater. However, the disadvantage is the very complex manufacturing of the slats and the visual disadvantage when the slats are open due to the curved shape of the slats.

[0003] The object of the invention is to overcome the disadvantages of known roofing systems and to further develop a roofing system that reliably drains rainwater and prevents contamination of the space beneath the roof when the roof is opened, particularly after rainfall. Opening the roof or the slats is understood to be synonymous with pivoting the slats into an open position.

[0004] This object is achieved according to the invention by a roof according to claim 1. Advantageous developments of the invention are specified in the subclaims.

[0005] Particularly advantageous in the case of roofing with at least two supports on which a plurality of slats are each pivotably mounted about a rotational axis, wherein the rotational axes of the slats run from one support to the other support, wherein the extension of the slats perpendicular to the rotational axes is limited by lateral ends of the slats, wherein the slats can be pivoted by means of a drive from a closed position, in which the slats form a closed roof surface, into any desired open position, so that part of the slats is pivoted downwards out of the closed position and another part of the slats is pivoted upwards out of the closed position, wherein when the slats are pivoted in the direction of rotation to the open position, each part of the slats pivoting downwards from the closed position of the slats has a drainage channel,that the drainage channel has a gradient towards a lateral end of the slat or that the drainage channel has two gradient sections, in particular starting from the centre of the slat, each in the direction of a lateral end of the slat.

[0006] This means that preferably each of the slats has such a drainage channel for draining rainwater, wherein the drainage channel has a gradient either to one side of the slat or preferably starting from the center of the slat, two gradient sections, each having a gradient in the direction of the two opposite lateral ends of the slat.

[0007] This allows precipitation and / or dirt collected on the slats to flow into the drainage channels of the respective slats, from where it flows off to the sides via the respective lateral ends of the slats without the need to tilt or bend the slats. Thus, the slope in the drainage channels ensures optimal rainwater drainage from the slats' drainage channels, especially with horizontally arranged slats.

[0008] It is particularly advantageous if the drainage channel has two gradient sections, particularly starting from the center of the slat in the direction of a lateral end of the slat, as this divides the incoming rainfall into two streams and even larger amounts of precipitation can be easily drained away via the lateral ends of the slats. The term "center of the slat" refers to the center with regard to the longitudinal extent of the slat, from the first lateral end of the slat to the opposite second lateral end of the slat, i.e. the center of the extension of the slat parallel to its axis of rotation. The first gradient section runs downwards to the first lateral end of the slat, while the second gradient section runs downwards to the opposite second lateral end of the slat.

[0009] This prevents precipitation and / or dirt collected on the slats from entering the space under the roof when the slats are opened.

[0010] In the closed position, the slats form a closed roof surface. The open position of the slats refers to a pivoted position of the slats deviating from the closed position, which in particular creates the maximum free roof area. In particular, the slats can be pivoted by 90° in the open position relative to the closed position. In particular, the slats can be aligned by 90° relative to the horizontal in the open position. In particular, however, the slats can be fixed in any intermediate position between the closed position and the open position, in particular by stopping the opening and / or closing process.In particular, the slats can be pivoted into any desired opening position in which the slats are pivoted by an angle of 1° to 175°, in particular by 45° or 60° or 75° or 90° or 105° or 120° or 135° or 140° or 150° or 165° or 175°, relative to the closed position.

[0011] When the slats are pivoted in the direction of rotation towards the opening position, a part of the slats is pivoted downwards, whereby this part of a slat has the drainage channel into which the rain hitting the slat flows off.

[0012] Each slat has a width, a height, and a length corresponding to the three spatial dimensions. The slats' axes of rotation run directly or indirectly from one support to another, whereby the actual length of the slat can be less than, equal to, or greater than the distance between the supports. The length of the slats parallel to their axis of rotation is limited by the lateral ends of the slats.

[0013] In particular, the drainage channel of the slat can be formed at least partially by means of a longitudinal edge of the slat running in particular parallel to the longitudinal extension.

[0014] In particular, each slat can be formed by a longitudinal profile, in particular a hollow profile. The longitudinal profile of each slat can be formed in one piece or in multiple pieces, in particular from several longitudinal profiles connected in a form-fitting and / or force-fitting and / or material-fitting manner.

[0015] In particular, the slats can each have a continuous cross-section.

[0016] In particular, the slats can each be pivotably mounted about an axis of rotation running parallel to their longitudinal extent.

[0017] In particular, precipitation can be detected using a rain sensor.

[0018] In particular, the canopy itself can have a control unit and / or be controlled by an external control unit. For this purpose, the control unit can be connected to the canopy via a cable and / or wirelessly, in particular via an infrared connection and / or a Bluetooth connection and / or a radio connection.

[0019] In particular, the supports can run parallel to each other. In particular, the supports can run at an angle to each other, with the length of the successive slats decreasing in accordance with the angle between the supports.

[0020] The two supports can each be mounted on a building. Alternatively, one of the supports can be mounted on a building. In this case, the support on the other side can be supported by at least one post, particularly a vertical one. Alternatively, the roof can be mounted freestanding and supported by several posts, particularly a vertical one.

[0021] Preferably, gargoyles are arranged at one or both lateral ends of the slat in the direction of one or both supports, via which the rainwater is drained from the drainage channel into gutters on one or both supports.

[0022] Such gargoyles on one or both lateral ends of the slat allow rainwater to be drained into gutters on one or both supports.

[0023] According to the invention, the slope or slope sections in the drainage channel are formed by an insert, in particular a plastic insert, inserted into the drainage channel. Such an insert simplifies the production of the slat, since the slope or the two slope sections are formed by the insert inserted into the drainage channel, while the slat itself is designed as an easily manufactured profile, for example, an aluminum profile.

[0024] The insert can be screwed to the slat and / or the insert can be fitted positively and / or force-fitted into the slat's drainage channel.

[0025] Preferably, the insert, particularly in the form of a plastic insert, has an oversize relative to the drainage channel in the direction of the slats' rotation axis and is clamped between the ends of the drainage channel, so that the insert curves upwards due to a prestress. Due to the oversize of the insert relative to the drainage channel of the slat in the direction of extension parallel to the slats' rotation axis, a prestress is automatically generated due to the clamping of the insert, which causes the insert to curve upwards and thereby form a sloping course, starting from the center and directed towards the two lateral ends, for the drainage of rainwater on both sides.

[0026] Alternatively or additionally, the insert can be supported centrally with a spacer element. Such a spacer element always results in an upward curvature of the insert, which in turn automatically creates a downward slope directed toward both lateral ends, starting from the position of the spacer element, preferably in the center, to drain rainwater on both sides.

[0027] Preferably, the part of the slats that pivots upwards from the closed position of the slats when the slats are pivoted in the direction of rotation to the open position has a lip. When the slats are pivoted in the direction of rotation to the open position, the part of the slat that has the drainage channel is pivoted downwards. Consequently, another part of the slat is pivoted upwards. This upwardly pivoting part of the slat preferably has a lip. In particular, such a lip can be formed by a longitudinal edge of the slat, which runs in particular parallel to the longitudinal extent, and / or by an additional rubber lip attached to the profile of the slat.

[0028] When pivoting the slats in the direction of rotation toward the open position, each part of the slats that pivots upward from the closed position of the slats preferably has a lip, wherein, at least in the closed position of the slats, the lip of a first slat and the drainage channel of an adjacent slat facing the lip engage with each other. The lip of the first slat and the drainage channel of the adjacent slat can correspond and interact in a manner similar to the so-called male-female principle.

[0029] Preferably, each part of the slats that swings upwards from the closed position when the slats are pivoted in the direction of rotation to the open position has a lip, wherein the lip of a first slat corresponds directly or indirectly, in particular via at least one sealing element, in a sealing, in particular watertight, manner with the drainage channel of an adjacent slat. As a result, in particular if water overflows over the drainage channel, no water can flow between the lip of the first slat and the drainage channel of the adjacent slat. This prevents water and / or dirt from getting between the slats and into the space beneath the roof during heavy rainfall when the slats are in the closed position.

[0030] In particular, the lip of the first slat can form a water outlet to the drainage channel of the adjacent slat. This can optimize water drainage into the drainage channels.

[0031] In particular, at least one of the slats, in particular each slat, can have an upper surface coated in such a way that the water collected on the slat drains off easily. For this purpose, a coating can be water-repellent and / or particularly smooth. Alternatively or additionally, the surface of the upper surface can be machined and / or manufactured in such a way, in particular by filing and / or grinding and / or milling, that the surface is particularly smooth.

[0032] Preferably, at least one of the supports has a gutter. In particular, the gutter can be arranged laterally next to the support and / or running parallel to the support. This allows the water flowing from the drainage channels to be collected and drained away in the gutter. In particular, the gutter can be inclined relative to the horizontal.

[0033] The roof preferably has at least one, in particular vertical, post that supports at least one of the beams. One of the beams can be mounted on a building, while the other beam can be supported by the at least one post. In particular, each beam can be supported by at least one, in particular two, posts.

[0034] The roofing preferably comprises at least one, in particular vertical, post that supports at least one of the beams, wherein the post has a downpipe for draining water, in particular water from the beam supported by the post. In particular, the post can be formed by a hollow profile. In particular, in the case of a post formed by a hollow profile, the downpipe can be accommodated in the hollow profile of the post.

[0035] Preferably, the roofing has a frame formed from several supports. In particular, the frame can be supported by several posts, especially four, arranged at the corners of the frame. Alternatively or additionally, the frame can be mounted on one or more building lintels.

[0036] Preferably, at least one of the supports has a gutter, and the roofing has at least one post, in particular a vertical one, supporting the support. A first drainage bend is provided, leading from the gutter to the post, in particular to a downpipe arranged in the post. This allows the water from the gutter to be drained through the drainage bend to the post. This ensures adequate rainwater drainage.

[0037] However, it is particularly preferred that both supports each have a gutter, each of which leads into a downpipe. This allows the amount of precipitation hitting the roof to be distributed and drained away over both sides of the roof.

[0038] In particular, the gutter can be arranged laterally next to the support, running parallel to the support, and the drain bend can be guided through a notch in the support to the post and / or to the downpipe.

[0039] The roofing preferably has at least one rain sensor. This allows precipitation and / or the end of precipitation to be detected.

[0040] In particular, the rain sensor can be designed as a permanently energized contact or have a permanently energized contact. If water is present on the contact, the resistance and / or temperature of the rain sensor changes, allowing the detection of the onset of precipitation. The water on the rain sensor is evaporated by a certain amount of heat generated by the energization of the rain sensor, allowing the resistance and / or temperature of the rain sensor to change again after the end of precipitation. In this way, both the onset and the end of precipitation can be detected.

[0041] The roof preferably has a particularly programmable control unit, by means of which the drive is controlled. By programming the control unit, the roof can be adapted to the requirements.

[0042] Preferably, the onset of a precipitation phase is detected by a rain sensor, and the slats are pivoted from an open position to a closed position. This allows the slats to be controlled automatically depending on the start and / or end of a precipitation phase.

[0043] An embodiment of the invention is illustrated in the figures and explained below. They show: Figure 1 a roofing according to the invention; Figure 2 three slats according to Figure 1 ; Figure 3 a cross-section of the lamellae according to Figure 2 in closed position; Figure 4 a cross-section of the slats according to Figure 3in a first opening position; Figure 5 shows a cross section of the slats according to Figure 3 in a second opening position; Figure 6 shows the section A - A according to Figure 4 .

[0044] The figures are not drawn to scale. Identical components are designated by identical reference symbols.

[0045] The Figure 1 shows a perspective view of a roof according to the invention. The roof has four supports 1, 2, 3, 4, which form a frame of the roof. Several slats 10, 20, 30 are pivotably mounted on the supports 1 and 2. The slats 10, 20, 30 are inclined by 15° relative to the horizontal with respect to their longitudinal extent.

[0046] The slats 10, 20, 30 are pivoted by 90° relative to the closed position of the slats 10, 20, 30 in the direction of the open position of the slats 10, 20, 30.

[0047] By means of a drive (not shown), which is controlled by a control unit (also not shown), the slats 10, 20, 30 are pivoted from the closed position to the open position and back to the closed position, depending on user activation. In the closed position, the slats 10, 20, 30 form a closed roof surface.

[0048] The beams 1, 2, 3, 4 are supported by three vertical posts 5, 6, 7 and one further one in perspective according to Fig. 1 invisible posts at the corners between beams 1, 2, 3, 4.

[0049] The Figure 2 shows a perspective view of three slats after Figure 1 , namely a first slat 10, an adjacent slat 20 and a further slat 30. The slats 10, 20, 30 each have a longitudinal extension 55 and are limited by the lateral ends 210, 220.

[0050] The Figure 3shows a cross section of the lamellae after Figure 2 in the closed position, in which the slats 10, 20, 30 form a closed roof surface. The slats 10, 20, 30 are each designed as hollow chamber profiles. The slats 10, 20, 30 are also pivoted out of their closed position in the direction of arrow 50 in the image plane clockwise in the direction of rotation towards the open position. When pivoting in the direction of rotation towards the open position, the slats 10, 20, 30 each have a downwardly pivoting part 11, 21, 31, each of which has a drainage channel 15, 25, 35. Furthermore, the slats 10, 20, 30 each have an upwardly pivoting part 12, 22, 32.

[0051] When the slats 10, 20, and 30 are closed, the upwardly pivoting parts 12, 22, and 32 and the downwardly pivoting parts 11, 21, and 31 interlock. The upwardly pivoting parts 12, 22, and 32 seal tightly with the drainage channels 15, 25, and 35, so that in the closed position, no water can penetrate between the first slat 10 and the adjacent slat 20, or between the slats 10 and 30, thus creating a closed, rainproof roof surface. However, the water striking the slats 10, 20, and 30 can drain into the drainage channels 15, 25, and 35 of the slats 10, 20, and 30.

[0052] The Figure 4 shows a cross section of the slats 10, 20, 30 after Figure 3in a first opening position, in which the slats 10, 20, 30 are pivoted by 30° relative to the closed position in the direction of the opening position according to arrow 50. The downwardly pivoting parts 11, 21, 31 are each located geodetically below the upwardly pivoting parts 12, 22, 32. If there is still rainwater on the slats 10, 20, 30 due to previous precipitation, this water 51 also flows off to the side via the drainage channels 15, 25, 35, so that the space under the roof is not contaminated.

[0053] The Figure 5 shows a cross section of the lamellae after Figure 3 in a second opening position in which the slats 10, 20, 30 are pivoted by 90° relative to the closed position and a maximum opening of the roof area is created.

[0054] The Figure 6 shows the section A - A of the slat 20 after Figure 4Visible is the plastic insert 250 inserted into the drainage channel 25, which forms two sloped sections 211, 212, starting from the center of the longitudinal extension of the slat 20, to the lateral ends 210, 220 of the slat 20. Rainwater is drained from the drainage channel 25 to both sides via the two sloped sections 211, 212, as indicated by the arrows 230, 240. Further drainage of the rainwater occurs via gutters (not shown) on the lateral supports 1, 2 and further via downpipes integrated into the vertical posts 5, 6, 7.

[0055] By arranging two sloped sections 211, 212, the amount of precipitation hitting the roof is distributed, allowing even larger amounts of precipitation to be drained away. A particularly advantageous visual feature is that the slats 10, 20, 30 themselves can have a horizontal profile between the supports 1, 2, and the rainwater is drained away via the lateral ends 210, 220 of the slats 10, 20, 30 due to the slope 211, 212 arranged in the drainage channels 15, 25, 35 of the slats 10, 20, 30.
