Description
[0001] The invention relates to a louvered roof according to the preamble of claim 1.
[0002] Such louvered roofs are known from JP S63 236852 A, DE 616 449 C and FR 2 608 192 A1.
[0003] Such louvered roofs are known. In these known louvered roofs, it is common practice to rotate the louvers around an axis and position them vertically to move them into the open position. In doing so, a portion of the louvers swings downwards, so that this portion is located below a lateral gutter, allowing any rainwater on the louvers to drip uncontrollably into the space beneath the louvered roof.
[0004] The object of the invention is to overcome these disadvantages of known louvered roofs. Furthermore, it is desirable to additionally install photovoltaic modules on roofs for electricity generation.
[0005] This problem is solved according to the invention by a louvered roof according to claim 1. Advantageous embodiments of the invention are specified in the dependent claims.
[0006] A particularly advantageous feature of the louvered roof with a frame formed from several supports, wherein several louvers are arranged parallel to each other on the frame between two lateral supports and are mounted on the lateral supports, wherein the louvers cover the area spanned by the frame in a closed position and can be moved from the closed position to an open position, is that two adjacent louvers are coupled to each other by means of a hinge arrangement to form a pair of louvers, wherein lifting the hinge arrangement causes the coupled pair of louvers to be raised into an open position.
[0007] In the context of the invention, the term "hinge arrangement" refers to the arrangement of one or more hinges along the coupling area between two louvers. Two adjacent louvers are thus coupled to one another by the hinge arrangement, and lifting the hinge arrangement from the closed position of the louvers causes the pair of louvers to open into a pointed, roof-like shape. Because the movement of the pair of louvers from the closed to the open position is achieved by lifting the hinge arrangement and opening the pair of louvers, the louvers as a whole always remain above the side gutter, so that any rainwater on the louvers can always be drained away via the side gutter.
[0008] Preferably, each pair of coupled louvers is positioned in the open position, resembling a pitched roof, and the space between two pairs of louvers is left open. By opening all pairs of louvers, a significant portion of the roof area can be exposed, allowing ventilation of the space beneath the louvered roof.
[0009] Preferably, the louvers rest on support surfaces on the side supports when closed. In particular, the louvers can rest on seals arranged on these support surfaces. By arranging such seals on the support surfaces where the louvers rest when closed, a watertight seal is created, reliably preventing rainwater from entering the area under the louvered roof uncontrollably when the louvers are closed. Preferably, the louvers have sealing lips at the contact points with the adjacent pair of louvers, which form a watertight louver assembly when closed.Integrated rainwater grooves can be arranged on the longitudinal edges of the louvers facing the adjacent pair. These grooves allow any rainwater on the louvers to be channeled laterally into a gutter when the louver pairs are moved into the open position. Preferably, each louver pair is subjected to a force in the direction of the open position, particularly by a spring. Such a force in the direction of the open position can cause the louver pairs to automatically open. This force can be generated, in particular, by the arrangement of one or more springs, such as coil springs and / or leaf springs, on each louver pair. These springs can act directly or indirectly on the hinge assembly in the direction of the open position.Alternatively or cumulatively, spring forces can act on both lamellae of each pair of lamellae and cause the pair of lamellae to open.
[0010] Preferably, the louver pairs are held in the closed position against a force in the direction of the open position by means of a movable retainer, whereby the louver pairs automatically move into the open position when the retainer is lifted. This means that lifting the retainer causes the louver pairs to automatically open due to the force in the direction of the open position. The louvers are preferably geometrically designed such that a dead center position is avoided in the closed position, in which the louver pairs lie flat on the bearing surfaces of the side supports. This means that the louvers are geometrically designed such that movement from the closed position is only possible into the open position, without any self-locking in a dead center position.This can be ensured in particular by ensuring that the hinge axis of the hinge arrangement between the adjacent slats is always located above a force input into the slats of the slat pair, so that from the closed position only an opening towards the open position is possible.
[0011] Preferably, at least one of the ends of the hinge arrangement of each pair of louvers oriented towards the lateral supports has a protruding pin which engages in a coupling profile and / or a cam guide, so that raising the coupling profile and / or moving the cam guide causes the pairs of louvers to move synchronously into the open position and lowering the coupling profile and / or moving the cam guide in the opposite direction causes the pairs of louvers to move synchronously into the closed position.
[0012] The arrangement of such a coupling profile and / or a cam guide enables the synchronous movement of all slat pairs from the closed position to the open position and vice versa. This requires only raising or lowering the coupling profile or, alternatively or cumulatively, moving the cam guide. Each hinge assembly has a pin projecting axially, so that each hinge assembly is kinematically coupled to the coupling profile and / or the cam guide, allowing the slat pairs to be raised into the open position or lowered into the closed position.
[0013] Preferably, rollers and / or gliders are arranged on the sides of the louvers opposite the hinge arrangement, guided on guide rails on the side supports. The arrangement of such rollers or gliders on the sides of the louvers opposite the hinge arrangement allows for easy rolling or sliding on the guide rails of the side supports, so that the louver pairs can be moved from the closed position to the open position and vice versa with very little rolling or sliding resistance. The side of the louvers opposite the hinge arrangement refers to the end of the louver's longitudinal edge that, in the open position where the louver pairs are arranged in a splash guard-like configuration, remains on the side supports in the lower area.Since these areas are moved along the side supports due to the positioning of the slat pairs, the arrangement of rollers and / or sliders in the contact areas of the slats and the side supports significantly reduces the frictional resistance between the slats and the side supports, or the guide rails on the side supports.
[0014] Preferably, a rainwater drainage channel is arranged on one or both side supports, running beneath the louvers. Rainwater striking the louvered roof can be drained away via this drainage channel. The louvers can be sloped towards one of the two side supports on which the drainage channel is located. Because the drainage channel runs beneath the louvers, rainwater drainage is ensured without the risk of any rainwater entering the area beneath the louvered roof.
[0015] Preferably, the louvered roof has a drive for moving the louvers from the closed position to the open position and vice versa. In particular, this can be a linear drive that acts on a cam guide and / or a coupling profile.
[0016] According to the invention, at least one photovoltaic module is arranged on the hinge assembly of one or more pairs of louvers, and each module is simultaneously raised when the hinge assembly is lifted. Each photovoltaic module has a loop-shaped connecting cable. The loop-shaped connecting cable of each photovoltaic module makes it possible to arrange photovoltaic modules for power generation on the hinge assemblies and to raise them simultaneously when the pairs of louvers are raised.
[0017] Preferably, at least one photovoltaic module is arranged on one or more lamellae and / or pairs of lamellae; in particular, several photovoltaic modules can be connected in series, especially with a voltage of up to 120 V. A maximum voltage of 120 V is advantageous because a higher DC voltage can be life-threatening.
[0018] In a preferred embodiment, the louvered roof comprises one or more photovoltaic modules and at least one integrated inverter. In particular, a support beam and / or a post of the patio roof can have at least one integrated inverter. The integration of at least one inverter allows for a direct connection to a building's power grid and / or the direct supply of an AC outlet and / or an AC load.
[0019] Preferably, at least one of the supports has cable channels for accommodating cables, in particular for accommodating connection cables of photovoltaic modules. Because the supports have integrated cable channels for accommodating the connection cables of the photovoltaic modules, connecting the photovoltaic modules is possible in a particularly easy and advantageous manner, creating an overall visually appealing impression without any visually disruptive cables.
[0020] Preferably, the louvered roof has at least one electrical load, in particular a drive for raising the pairs of louvers. Specifically, the load can be powered directly by photovoltaic modules of the louvered roof and / or by at least one accumulator integrated into the louvered roof, the accumulator being charged by photovoltaic modules of the louvered roof. By providing an accumulator to power the drive of the louvered roof and supplying the accumulator via integrated photovoltaic modules, a completely self-sufficient louvered roof is created.
[0021] Preferably, the patio roof includes at least one battery that is charged by the photovoltaic module(s). Integrating such a storage unit for electrical energy improves the usability of the electrical energy generated by the photovoltaic modules, as the stored energy can be used at a time after its generation, for example, to power lighting after sunset.
[0022] Preferably, the frame is supported by several posts; in particular, the posts may have integrated cable channels for accommodating connection cables of photovoltaic modules and / or at least one socket, in particular at least one DC socket with an operating voltage of 12 V or 24 V and / or at least one AC socket with an operating voltage of up to 230 V.
[0023] By integrating one or more DC and / or AC power outlets, it is possible to directly connect devices to the patio roof, such as chargers and / or mobile devices, radios, lamps and the like.
[0024] Preferably, the louvered roof has at least one integrated socket for connecting electrical appliances. In particular, a socket can be provided which is supplied by a battery integrated into the patio roof, wherein the battery is charged by photovoltaic modules, and / or wherein the socket is supplied directly by photovoltaic modules, in particular via at least one inverter integrated into the louvered roof with an alternating voltage of up to 230 V.
[0025] Preferably, the terrace roof has at least one electrical consumer that is directly powered by the photovoltaic modules and / or that is powered by at least one accumulator integrated into the terrace roof, the accumulator being charged by the photovoltaic modules.
[0026] A particularly desirable feature of a patio roof is at least one lighting unit and / or at least one Wi-Fi repeater. Specifically, the lighting unit and / or the Wi-Fi repeater can be powered directly by photovoltaic modules and / or by at least one battery integrated into the patio roof, which is charged by the photovoltaic modules. The space under the louvered roof can be illuminated by the arrangement of one or more lighting units. If these lighting units are powered by an integrated battery, i.e., a storage unit for electrical energy, the lighting can be activated at a time staggered from the generation of the electrical energy, for example, after sunset.
[0027] A Wi-Fi repeater serves to increase the range of a wireless network. By installing a Wi-Fi repeater, which can be powered by at least one battery integrated into the louvered roof (charged by photovoltaic modules), it is possible to extend a local wireless network to the area below and near the patio roof.
[0028] In a preferred embodiment, at least part of the lamella pairs are movable in the open position along guide rails on the lateral supports between a closed position, in which the lamella pairs are evenly distributed over the area spanned by the frame, and an open position, in which the lamella pairs are pushed together to form a package at one end of the area spanned by the frame.
[0029] By allowing the installed pairs of louvers to be moved further along guide rails on the side supports, the area covered by the louvered roof can be opened further.
[0030] Preferably, the louvered roof has two separately controllable drives, the first drive being used to raise the louver pairs from the closed position to the open position and vice versa, and the second drive being used to move the louver pairs in the open position along the guide rails between the closed and open positions. The drives are configured such that moving the louver pairs in the open position along the guide rails between the closed and open positions using the second drive is only possible when the louver pairs are in the open position, i.e., when the louver pairs are set in a pitched roof shape.Conversely, lowering the erected pairs of louvers from the open position to the closed position using the first drive is only possible if the pairs of louvers have previously been moved to the closed position using the second drive, in which the pairs of louvers are evenly distributed over the area spanned by the frame.
[0031] Preferably, the second drive is formed by at least one driven traction element, in particular a driven belt, in particular a driven toothed belt, which engages directly or indirectly on the last pair of lamellae in the extension direction, and wherein the pairs of lamellae are each coupled by collapsible or flexible coupling elements, such that when the last pair of lamellae in the extension direction moves in the retraction direction, the pairs of lamellae slide together to form a package with the coupling elements automatically collapsing, and wherein, when the last pair of lamellae in the extension direction moves in the extension direction, the pairs of lamellae are arranged evenly distributed over the area spanned by the frame due to the coupling elements.
[0032] In this case, the louvered roof has two separately controllable drives. The first drive is used to raise and lower the pairs of louvers between the closed and open positions. In the closed position, the louvers lie in the plane defined by the frame of the louvered roof, forming a closed roof. From this closed position, the louvers can be moved to an open position by the first drive, which raises the hinge assembly of each pair of louvers. In the open position, the pairs of louvers are arranged in a pitched roof shape. In this open position, the louvers can be moved from the closed to the open position along the guide rails using the second drive.The closed position refers to the arrangement in which the pairs of louvers are evenly distributed across the plane defined by the frame of the louvered roof, allowing them to be lowered into the closed position. The open position refers to the arrangement in which the pairs of louvers are pushed together at one end of the guide rails, forming a stack and exposing part of the plane defined by the frame. When the pairs of louvers are pushed together in this stack, they cannot be lowered into the closed position.To prevent damage and incorrect operation, the control of the two drives is designed in such a way that lowering the slat pairs using the first drive is only possible in the closed position, and moving the slats using the second drive is only possible when the slat pairs are in the open position.
[0033] The terms closed position and open position thus refer to the relative position of the louver pairs as a result of raising the hinge arrangements of the louver pairs relative to the plane spanned by the frame of the louvered roof.
[0034] The terms "closed position" and "open position" refer to the distribution of the louvers across the plane spanned by the frame of the louvered roof. In the closed position, the pairs of louvers are evenly distributed across the plane spanned by the frame, while in the open position, the pairs of louvers move along the guide rails on the side supports and are pushed together into a stack at one end of the guide rails.
[0035] The direction of travel of the movable louver pairs towards the closed position, with the louver pairs evenly distributed across the plane spanned by the frame, is referred to as the extension direction. Conversely, the opposite direction of travel is the direction of travel of the movable louver pairs towards the open position, with the louver pairs pushed together into a stack at one end of the louvered roof.
[0036] Two exemplary embodiments are shown in the figures and are explained in more detail below. They show: Fig. 1 A perspective view of a first non-inventive embodiment of a louvered roof with louvers in the closed position; Fig. 2 A perspective view of the louvered roof according to Figure 1 with louvers moved into the open position; Fig. 3 a schematic representation of a pair of louvers in the closed position and in the open position; Fig. 4 a perspective view of a second embodiment according to the invention of a louvered roof with louvers moved into the open position and photovoltaic modules.
[0037] Figure 1Figure 1 shows a perspective view of a first, non-inventive embodiment of a louvered roof 1 with louvers 3 in the closed position. The louvered roof 1 has a frame formed by the side supports 2 and the crossbeams 2'. Several louvers 3 are arranged parallel to each other between the two side supports 2 and are mounted on the side supports 2. The frame of the louvered roof 1 is supported by vertical posts 4.
[0038] Figure 2 shows a perspective view of the louvered roof 1 according to Figure 1 with the slats 3 moved into the open position. The mechanism for setting up the slats 3 is explained using Figure 3 explained.
[0039] Each pair of adjacent lamellae 3, 3' is coupled to each other by means of a hinge arrangement 5 and forms a lamella pair 30. Figure 3The louvers 3, 3' are in the closed position in the left part of the image and in the open position in the right part. To move the louver pair 30 from the closed position to the open position, the hinge assembly 5 is lifted as indicated by arrow 5'. As a result, the louver pair 30 is moved as shown in the right part of the image. Figure 3 shown positioned in a pointed roof shape and moved into the open position. Figure 2 It is evident that all pairs of louvers 30 have been moved into the open position.
[0040] The hinge arrangement 5 of each pair of slats has a pin or tenon projecting towards a lateral support 2, which engages in a cam guide. By moving the cam guide in a direction parallel to the lateral support 2, all pairs of slats 30 are synchronously moved from the closed position according to Figure 1 into the open position according to Figure 2relocated and set up, as shown schematically in Figure 3 This is shown. This releases the space between the pairs of louvers 30 and ventilates the space under the louvered roof 1.
[0041] Figure 4 Figure 1 shows a perspective view of a second embodiment of the invention, a louvered roof 1, with louvers 3 and photovoltaic modules 6 in the open position, which are arranged on the hinge assemblies 5 of each pair of louvers 30 and are raised along with them. The basic structure of the louvered roof 1 according to Figure 1 is shown. Figure 4 corresponds to the first embodiment with a frame formed from beams 2, 2', which is supported by vertical posts 4.
[0042] In the exemplary embodiment according to Figure 4A photovoltaic module 6 is arranged. These photovoltaic modules 6, along with the hinge assembly 5, are lifted when the pairs of louvers are moved from the closed position to the open position. To enable the electrical connection of the photovoltaic modules 6, connecting cables are provided, which are laid out in a loop and thus allow the photovoltaic modules to be lifted.
