Description

The invention relates to a vertical blind system with a support structure that can be fixed to an attachment means comprising a first support and a second support and at least one guided blind.

Generic vertical blind systems are known from the state of the art for exterior cladding of window surfaces or terrace windows. The blinds are generally arranged so that they can be rotated, whereby a central drive and a central control are provided, by means of which the position of the blinds is influenced. The rotation of the blinds in the state-of-the-art vertical blind systems can generally only be adjusted in their entirety (e.g., all the blinds in 45° position). Furthermore, the distance between the single blinds in the known devices is fixed by the design and cannot be changed.

In practice, this leads to some disadvantages. It would be particularly desirable, if on a window surface provided with outer blinds different rotational positions of the blinds could be set depending on their respective position. In addition, it would also be advantageous to provide a high number of blinds in certain areas, while other areas would remain free of blinds.

However, the state-of-the-art blind systems do not allow user-defined control of the position and pivoting of each single blind.

However, it is known from the state-of-the-art to combine vertical blind systems into groups that can be adjusted independently of one another. For example, DE 10 2009 042846 A1 discloses a blind system with two blinds connected by means of a joint. However, this in turn leads to the problem that the corresponding grouping of the blinds must already be known when planning the system. An individual adaptation to the needs of the user is therefore not possible.

Thus, the object of the present invention is to create a vertical blind system in which both the rotational position and the lateral position of each individual blind can be adjusted not only conventionally uniformly, but also individually and independently of the other blinds in order to achieve any desired facade appearance and to respond optimally to the wishes of the user.

In the invention, this object is solved by a vertical blind system according to claim 1. The blinds can be separately controlled and separately moved and rotated by at least one drive, wherein the each blind comprises one axis and a first chassis as well as a second chassis and a blind leaf which is rotatable thereto.

This provides for the first time a vertical blind system in which the lateral position and rotational position of each blind can be adjusted independently of the other blinds. The translatory movement and rotation of the blinds can take place after logistical optimisation, for example to conduct or block solar heat into the house in certain areas. Individual facade pictures and facade protection functions are possible. In a first possible embodiment according to the invention, each single blind can comprise a drive and preferably a control, wherein the drive is realised as a moving drive and/or rotating drive. In a second embodiment, a central drive can be provided which drives a traction means, each single blind comprising an activatable coupling for engagement with the traction means.

At least one current collector may be provided on the first chassis and/or the second chassis or inside the blind for the supply of energy and for the transmission of control and sensor signals, which in operation is in communication with at least one energised electrical line of the support structure. The current collector can be in the form of a sliding contact and the electrical line in the form of a multipole conductor line.

Alternatively, the current collector may comprise at least one collector ring realised as part of a blind bearing, which in operation taps a multi-pole brush contact on the first chassis or the second chassis and which is in communication with the drive and/or the control via electrical lines. The collector ring may preferably be connected to the blind axis and can be rotated through 360°. This embodiment of the current collector enables an endlessly rotatable blind leaf. The collector ring can also be provided in a chassis of the blind or inside the blind. Several electrical contacts can be provided on the collector ring in a known manner, which are on the one hand tapped from the multi-pole brush contact and on the other hand contacted by electrical lines. The lines can preferably be routed to the drive or control through the axis of the blind or while being in contact with it.

The electrical line can also transmit sensor data or other electrical signals. In addition or alternatively, wireless data transmission can be provided, for example. External sensors (e.g. temperature or rain sensor) can be integrated. The drive status of each single blind can be reported to the outside. The power supply can be DC or AC. The drive can be an electric motor, preferably a DC electric stepper motor. The drive may mesh with a transmission and the axis and at least one tooth wheel may be provided being attached to the axis, which is in form-locked contact with at least one toothed rack provided on one of the supports.

Instead of the combination of tooth wheel and toothed rack, other form-locked transmission means (cable pull, chain or the like) are of course also possible. The form-locked transmission of the drive guarantees that the transmission positions on both supports are the same. A change-over bar may be provided on the blind leaf, which during change-over between moving drive and rotating drive rigidly couples the blind leaf to the first chassis and/or the second chassis. The blind can rotate preferably or only in the locked position. The angle of rotation of the blind can be variable without steps or preferably in steps of 10° from the transverse position 0° to 45° - left and 90° -right. Moving of the blind is preferably performed in the 0° position. The toothed rack can have recesses for locking the blind at predetermined positions which correspond to corresponding fixing means (pins, bolts or the like) on the blind.

The first chassis and/or the second chassis may be provided with rollers which are guided in corresponding recesses of the first support and/or the second support. In order to reduce the parking space required, the chassis and/or the rollers of adjacent blinds are preferably arranged offset relative to one another along the axis. Preferably every second chassis can be arranged in the same position along the axis.

At least one energy store can be provided in the blind to ensure operation of the system in the event of a power failure. This can be a battery or a rechargeable battery. The drive and/or the control may be connected or connectable via a bus system to a central system control. This can be any bus system that is suitable for controlling home electronics.

The blind leaf can have a cladding which preferably comprises metal, glass, stone, textiles, plastic and/or wood in a continuous, perforated, translucent and/or opaque finish.

This ensures that the blind is opaque and storm-proof, especially in the closed state. In particular, there may be provision for additional lips on the long sides of the blind, for example made of rubber, so that the blinds can be tightly connected when closed. This does not necessarily include a waterproof connection.

The blinds and/or cladding may include lighting elements, in particular light emitting diodes, photovoltaic elements for current generation, or sound protection elements. In particular, it may be provided that the blinds comprise photovoltaic elements for current generation, in particular integrated in the cladding of the blind leaf. This allows electrical energy to be generated which can be used to charge an energy store on the blind and/or can be dissipated via electrical collector lines. An intelligent system can also be provided in the background that reacts to climatic conditions and adjusts the position of the blinds accordingly in order to optimise the energy yield. The lighting elements on the blinds make it possible to create light effects, in particular to simulate a wave movement by rotating the blinds accordingly. It is also possible to display a certain lighting (e.g. Christmas lighting), a pattern or an advertising subject on the blind system. In particular, the front and rear of the blinds may be designed differently in order to allow at least two different facade designs.

The blind is preferably shaped in a way that wind loads can be absorbed at low deflection and transferred to the supports. Environmental influences such as rain, snow, hail, leaves or dust should not cause any functional impairment. Running tracks may be provided on at least one of the supports and corresponding support rollers may be provided on the blind for guiding the blind. The running tracks can also be in the form of strips or grooves.

The blind can have at least one pair of rollers engaging in at least one recess of the first support and/or the second support. While the support rollers also serve to transfer the weight of the blind, the primary purpose of the support rollers is to ensure clean and smooth running of the blind.

Locking marks may be provided on the toothed rack for locking the blind at predefined positions, which are engaged by a locking lever attached to the first chassis and/or the second chassis. For this purpose, the locking marks can preferably be in the form of recesses or in the form of pins or bolts. When the change-over bar is operated, the locking lever may engage with the locking marks, so that the blind leaf can only be rotated when the blind is locked.

As stated above, the drive may also be attached to the support structure instead of the blind itself and the blind, preferably the first chassis and/or the second chassis, may be connected in a form-locked manner to this drive via a pulling means and a preferably remote-activatable coupling. The pulling means can be designed as a preferably revolving toothed belt or preferably a revolving chain. The coupling of the blind can be designed as a snap coupling which engages in the pulling means. The attachment of the blind system and/or the supports may comprise means for draining off water.

The invention also includes a facade structure comprising at least one blind system according to the invention. The facade construction according to the invention can be attached in particular to the outer surface of a facade, a terrace, a window frame or a door or gate frame.

The supporting structure can be horizontally aligned and, in particular, take over the drainage of rainwater. The electrical supply cables can be routed in their own external posts, whereby the dimensioning should preferably be in accordance with the respective object grid and local wind loads.

Further inventive features can be derived from the claims, the description and the drawings.

The blind system according to the invention is now explained by means of several embodiments.

Fig. 10 shows a detail of another embodiment of the vertical blind system in cross-section.

Fig. 1 shows an embodiment of a blind system according to the invention in exploded view. The system comprises a support structure 21 with a first support 1 and a second support 8, which are attached to the attachment means 7 with suitable fastening means. In particular, this can be an attachment to a facade or the outer frame of a window, a terrace, a gate or a door. The supports 1,8 run preferably in horizontal orientation, but it can also be provided that the supports 1, 8 run in vertical direction.

In this embodiment, the first support 1 is provided at the top and the second support 8 at the bottom. Running tracks 2 are provided in the second support 8 arranged below, which serve to enable the guide of support rollers 16 on the blind 9 with as little friction as possible. Running tracks 2 are designed as round webs which engage in correspondingly designed rollers. However, another version of the running tracks 2 is also possible, for example in the form of a strip. Furthermore, the blinds 9 are guided on the side walls of the support profile.

In addition, both the first support 1 and the second support 8 are designed as a C-shaped profiled sheet, the two legs of the supports 1,8 being designed to engage laterally mounted rollers 17 of the blind 9. While the running tracks 2 are primarily used to transfer the weight of the blind 9 and to form the most possible linear contact surface, the legs of the supports 1, 8 are primarily used to guide the blind 9 safely and with little clearance and to ensure smooth running when actuating the system. In order to prevent impairments due to contamination and to cause as little friction as possible during load transfer, the cross section of the running tracks 2 is convex in the direction of the blind 9 and, in particular, has an approximately circular or semicircular cross section. The contact area between blind 9 and running track 2 is thus reduced to one line, and contamination has only a minor effect. A toothed rack 3 is provided on the first support 1 and on the second support 8, into which tooth wheels 14 engage on a first, preferably upper, chassis 13 and a second, preferably lower, chassis 15 of the blind 9. The mechanical drive of the blind 9, which can be displaced or moved along the toothed rack 3, is effected by the form-fitting engagement of the tooth wheels 14 in the recesses of the toothed rack 3.

To fix the position of blind 9, locking marks 4 are provided on the toothed racks 3 in the form of recesses, in particular also holes or punches, into which corresponding fixing means (pins, bolts or the like) of blind 9, in particular the locking lever 23 explained below, can engage. Alternatively, the lock can also be provided on the support itself. The blind 9 comprises a first chassis 13, a second chassis 15 and a blind leaf 6. The blind leaf 6 is rotatable in relation to the chassis 13, 15 and can be displaced together with these. The two trolleys 13, 15 are connected via axis 24. The drive 22 and a control 19 are attached to the blind leaf 6. Control 19 supplies the drive 22 with control commands (start, stop, rotation, etc.). The control 19 is connected to a central control unit via a bus system.

Drive 22 is preferably designed as an electric motor, in particular as an electric stepper motor. The shaft of drive 22 is connected to axis 24 of blind 9 via a transmission. The axis 24 is rotatably mounted by the blind bearings 11, which are preferably mounted in the upper and lower area of the blind 9. The Axis 24 is coupled at both ends with tooth wheels 14, which engage in the toothed racks 3 of the supports 1, 8, whereby a translatory movement of the blind 9 is achieved. The blind bearings 11 can be designed as standard ball bearings or plain bearings.

When the change-over bar 18 is actuated, the translatory position of the blind 9 along the running track 2 is fixed by a locking lever 23 (not shown) connected to the chassis 13, 15 engages in the locking marks 4 of the toothed rack 3. This causes the blind leaf 6 to rotate about axis 24 relative to the chassis 13,15, which are fixed in this case, when the axis 24 is rotated further.

To safely guide the blind 9 in the support structure 21, the blind 9 has several rollers 17, preferably at its upper and lower end, which engage in the C-shaped legs of the first support 1 and the second support 8, respectively. In addition, the support rollers 16 are provided at the lower end of the blind 9, which engage in the running tracks 2 of the second support 8 for load transfer.

Preferably, current collectors in the form of multipole sliding contacts 20 are mounted on the upper chassis 13, which interact with corresponding sliding lines 5 in the first support 1 of support structure 21. This enables each blind 9 to be supplied with electrical energy even during movement and in particular also during rotation of the blind 9. For this purpose, the sliding contacts 20 are part of the chassis 15 and uncoupled from axle 24, so they do not rotate when the blind 9 rotates.

The blind leaf 6 is covered with a cladding 12, which in particular may be a sheet metal or a textile. Furthermore, a blind lip 10 is provided along the blind leaf 6 in order to allow a closure between the blinds 9 when the blinds 9 are in a closed position with regard to opaqueness, noise tightness and the like.

Fig. 2a shows a schematic representation of the blind system in three-dimensional view when closed. The blind leafs 6 are rotated by approx. 90° in relation to the chassis 13,15, thereby ensuring that the blind leafs 6 safely cover the area to be protected, while the chassis 13, 15 remain in connection with the toothed rack 3 and the first support 1 and the second support 8 respectively. Fig. 2b shows the same view when open. The blind leafs 6 are not twisted in relation to the chassis 13,15, because the blind leafs 6 expose the area to be protected. By individually controlling each single blind 9, the angle of rotation of each blind leafs 6 and the position of each blind 9 can be selected independently. This allows fully individually adjustable facade images to be achieved.

Figs. 3a - 3c show an elevation view of the blind system according to the invention in closed, open and parked condition. The single blinds 9 are arranged in a system grid. However, the individual movability of the blinds 9 ensures that the blinds can also be moved closer together or further apart independently of one another. An angle of rotation of the blind leaf of about 270° can be guaranteed.

When closed (Fig. 3a) the blind leafs 6 is rotated by approx. 90° relative to the chassis 15. In the open state (Fig. 3b) the blind leaf 6 is arranged approximately in line with the chassis 15. When parked, the single blinds 9 are pushed together and require only little storage space. The total thickness of the blinds 9 is about 50mm, so extremely little parking space is required. In this case, a blind width of 400 mm can be provided. Blinds with higher overall thickness can also be used if the strength and rigidity of the structure requires it. However, the shape of the blind is essentially determined by light-technical considerations and depends on the respective application.

Fig. 4a and Fig. 4b show the function of the change-over bar 18 and the locking lever 23. In the unlocked and thus movable state (Fig. 4a) the change-over bar 18 is not activated and points in the direction of the support 8. The change-over bar 18 is in contact with one end of a locking lever 23, whereby the other end of the locking lever 23 is raised and turned away from the locking mark 4. When the change-over bar 18 is activated, it is raised and releases the locking lever 23, which falls (at the next opportunity) into a locking mark 4 and blocks the further movement of the blind 9. The activation of the change-over bar preferably is done by an electromagnetic drive.

Fig. 5 shows a further cross-section of an embodiment of the blind system according to the invention, with the cladding 12 of the blind leaf 6 in particular being shown. The blind leaf 6 is in a position which is approximately 45° rotated in relation to the second chassis 15, and the locking lever 23 depicted in dashed lines is engaged in a locking mark 4.

Fig. 6 shows a blind system according to invention with four independently rotatable and movable blinds 9. In order to achieve the smallest possible storage space when pushed together, the chassis 13 of the single blinds 9 are arranged offset from one another in the direction of the axis 24 of the blind in such a way that every second chassis comes to lie at the same position.

This ensures that the blinds lie particularly close together in the parking position. Both toothed rack 3 and the C-shaped recess of the supports 1,8 are appropriately dimensioned to accommodate two offset chassis 13, 15 with their tooth wheels 14 and rollers 17.

Fig. 7a - 7d show a facade construction according to invention with two vertically arranged blind systems 25. The facade construction is in Fig. 7a in open condition, in Fig. 7b in parked condition, in Fig. 7c in closed condition and in Fig. 7d in partially open condition. The parking area 26 is located in the lower part of the structure. As can be seen in Fig. 7d, any facade image can be achieved by the blind systems 25 according to the invention.

Fig. 8a - 8d show a facade construction according to invention with two horizontally arranged blind systems 25. The facade construction is in Fig. 8a in parked condition, in Fig. 8b in open condition, in Fig. 8c in closed condition and in Fig. 8d in partially open condition. The parking area 26 is located on the right-hand side of the structure. As can be seen in Fig. 8d, any facade image can be achieved by the blind systems 25 according to the invention.

Fig. 9a - 9b show a facade construction with three horizontally arranged, wavelike blind systems 25 in elevation and in three-dimensional view.

Finally, Fig. 10 shows a cross-sectional detail view of another embodiment of the blind system 25 according to the invention. In this design the current collector is designed as collector ring 27. This allows the blind 9 to be rotated 360° about its axis 24 without any risk of the connecting cables of drive 22 or control 19 getting tangled. This allows the blind leaf 6 to rotate endlessly about axis 24. The blind bearing 11 comprises a collector ring 27, which is connected to axis 24 and extends into the first chassis 13. In the area of the first chassis 13, the collector ring 27 has a multi-pole contact area on its outer circumference, which interacts with the brush contacts 28.

The brush contacts 28 are fixed in the first chassis 13 and can be moved with it, but cannot be rotated. The brush contacts 28 are connected to the electrical sliding contacts 20 by electrical cables. The sliding contacts 20 in turn are in contact with the fixed sliding line 5 on the first carrier 1.

The invention not only extends to the embodiments given as examples, but also includes further alterations within the scope of the patent claims. In particular, the invention is not limited to the described embodiment of the blind.
