    Lamellenbehang
    The invention is a Lamellenbehang comprising a plurality of mutually spaced, interconnected slats according to claim 1.
    Lamellenbehänge or lamellar blinds, as they are known today in many embodiments, comprise a plurality of lamellae, which are connected by ropes which are attached to the longitudinal edges of the slats, connected to each other and pivotable by turning mechanisms. Next include the known slats elevator belts, which usually pass through holes in the central region of the slats to a arranged below the bottom slat end rail. Above the elevator belts can be wound up on a drum in order to be able to pull the slats together as a package and thus release the window or door opening. At their front ends, the slats are guided either in guide rails or on them penetrating tensioned cables. For mounting and lowering or for pivoting the slats, cranks can be provided with hand-operated gearboxes or electric motors. The latter are often connected to manually operated buttons or to a bus system and controlled by the angle of light, brightness and / or wind speed. The latter is measured and, if a predefinable value is exceeded, the hoisting of the blind is activated by a control to protect the blind.
    In the case of a sunny façade, the slat blinds are extended as required for the purpose of sun protection and glare protection in the clear cross section of the window. The slats can then be turned into an optimal position. If the position of the sun changes, the slat angle can be adjusted manually or automatically. If the facade is no longer sunburned, the curtain is usually retracted, but often left in the respective position. Depending on the application, the slatted blinds are also closed at night for the purpose of darkening, privacy and burglar resistance. Not only from a definable wind strength, but also at risk of frost, the known fins must be retracted.
    The daytime more frequent extension and retraction of slat blinds has several disadvantages. With short-term occurrence of strong sunlight Storen need some time, until they are completely extended and the space can be shaded. In this time, the sun and glare protection is not active. Especially with automatic control of the sunscreen / glare protection is delayed activated to avoid unnecessary interference from driving noise and frequent light changes in changing clouds. The wind stability of such blinds is limited due to their functional design. The benefit of these products is therefore often no longer given at higher wind speeds. Even with frost, most known products must remain retracted for safety, so that a glare protection can not be maintained.
    Experiences further show that the sunscreen often remains extended during manual operation throughout the day and depending on the position of the sun and brightness only the slats angle can be adjusted. With horizontally placed slats the view to the outside is practically not affected, so that the user has no need to retract the sunshade, although this is no longer necessary and inevitably leads to a reduction in the incidence of light, and the lighting must be switched on, although this opened store would not be necessary.
    An object of the present invention is therefore to provide a Lamellenbehang, which is simple in construction and inexpensive to produce and yet fulfills all functions of the sun and glare protection, the Nachtabdunkelung and a certain burglar resistance.
    This object is achieved by a Lamellenbehang according to the features of claim 1. Advantageous embodiments of the slat blind are described in the dependent claims.
    The inventive Lamellenbehang is structurally inexpensive and thus inexpensive to produce, since only a simple turning device, but not a combined with the turning device elevator device is necessary. Also elevator belts as well as a final rail are not needed. Both sides mounted guide rails or guide ropes at the front ends and possibly additionally in the middle of the store are not needed. For the turning of the lamellae motors can be used with compared to elevator motors very low power or a simple manually operated with a cord or a crank turning device. The store can be firmly inserted into a window opening and fixed there above and below or laterally. To clean the windows on fixed windows, the store can be detached from its fixture, allowing access to the windows. By both the top and bottom fixation of the store, this store can be exposed to increased wind load and reaches the necessary wind stability permanently. Hoisting in stormy winds is therefore not necessary. In addition, there is no risk of frost damage, since the existing moving elements do not respond to ice or can be destroyed by ice. Furthermore, adjusting the slat angle is very easy and noiseless. Optimum light control is easy thanks to the reduced turning speed. The multiple attachment of the store at its lower end ensures good burglar resistance. In addition, a lintel for a wound-up lamella package falls away and thus no elaborate insulation of the lintel niche is necessary in the upper window area. In addition, larger window widths with a single store and over the entire width of the window extending lamellae protect against light. The unnecessary lift belts result in shapely designed slats and favor the incidence of light as well as the aesthetic appearance of a façade. The interface for the control of the turning device corresponds to that of standard gates and is therefore inexpensive to buy. The simplicity of the design allows the use of extremely small simple DC drives, which can be connected to compatible standard interfaces or to simple switches. By the only necessary turning function cost-effective bearings can be used on the turning elements. The device for turning can be made by means of maintenance-free scenes. The installation on windows can also be done later on existing buildings without much effort.

    In Fig. 1, a slat blind, curtains 1, is shown in a first embodiment in side view or section. For better clarity, the curtain 1 is shown with only three fins 3. Of course, hangings usually have a much larger number of slats 3. The lamellae 3, usually made of an aluminum strip, are connected at their two longitudinal edges in each case with two or more connecting means 5 and 7. Hereinafter, the external or weather-side connecting means is referred to as outer cable 5 and the inner connecting means arranged towards the interior of the building are referred to as inner cable 7. The connecting means may be formed as cables, bands or cords on the metal or plastic. Below the lamella 3 at the bottom, the lower reveal 9, also called the ledge, is shown schematically. The upper reveal and the lateral reveal of a window are not shown for the sake of clarity.
    The outer cable 5 is extended beyond the bottom slat 3 out and firmly connected to the lower soffit 9 at the point A. The upper end of the outer cable 5, which protrudes beyond the lamella 3 at the top, is connected to a lateral disguise or to the above-lying soffit (also not shown) at the point B. The connection of the outer cable 5 with the soffit of the window can be done with screws or dowels. The inner cable 7, which connects the inner longitudinal edges of the lamellae 3, extends beyond the uppermost lamella 3 and is fixed to a turning device 11, for example a shaft rotatable about a fixed axis or rotatably mounted on the axis and connected to the latter connected. The turning device 11 is formed fastened in the reveal of the window. A first spring 13, for example a metal coil spring or a rubber spring, is inserted between the uppermost lamella 3 and the turning device 11. The turning device 11 can be rotated back and forth by a predetermined angle with a hand crank, a turning device 11 at least partially wrapping chain (chain not shown) or an electric motor (not shown).
    The connection between the outer cable 5, the inner cable 7 and the edges of the slats 3 can be done in a known manner by attached to the outer cable 5 and the inner cable 7 brackets 15. The brackets 15 allow free movement of the slats 3 with respect to the outer cable 5 and inner cable 7. The brackets 15 may be made of plastic or metal and are fixed or hinged to the longitudinal edges of the slats 3. The outer cable 5 and the inner cable 7 can each be made in one piece or the ropes 5, 5 arranged in pairs can be made up of individual sections which each lead only from lamella 3 to lamella 3 or brackets 15.
    In Fig. 1, the open position is shown, that is, the slats 3 are substantially horizontal and affect the incidence of light to a room and the view from the room only insignificantly.
    In Fig. 2, the shading position is shown, that is, the slats 3 are at an angle of about 45 ° -30 ° to the vertical.
    The outer edges of the slats 3, which are connected to the outer cable 5, regardless of the position of the slats 3 always remain stationary, since the outer cable 5 is kept taut between the points B and A. By a rotational movement of the turning device 11 in the clockwise direction, the inner cable 7 is wound on the drum of the turning device 11 slightly. The inner edges of the slats 3 are pulled up. The first spring 13 remains unstressed, since the lamellae 3 is opposed to their mass no resistance.
    In the closed position, as can be seen in Fig. 3, the slats 3 are approximately vertical and can even overlap touching each other. The first spring 13 is still unstressed.
    The position of the slats 3 according to FIG. 4 substantially corresponds to the position of the slats 3 according to FIG. 2. However, the lamellae 3 according to FIG. 4 are now in an unstable position, since the lamellae 3 are guided out of the essentially vertical position according to FIG. 4 into the inclined position by the force F generated by strong wind. In this case, the first spring 13 is tensioned more or less in accordance with the force F of the wind. If the force F of the wind is omitted, the lamellae 3 return to the closed position according to FIG. With this elastic "suspension" of the inner edges of the slats 3 their damage can be prevented by strong wind.
    In the second embodiment of the invention according to FIGS. 5-8, the outer cable 5 is not connected at its lower end with the soffit 9, but with an extended portion of the inner cable 7. The extended portion of the inner cable 7 leads from the inner edge of the lowermost blade 3 via a deflection 17, for example a deflection roller or a deflection shoe to the end of the outer cable 5 and is connected thereto. Between the deflection 17 and the lowermost blade 3, a second spring 19 is inserted in the inner cable 7, which is unstressed in the open position, that is to say in a horizontal position of the blades 3 as well as the first spring 13 arranged at the top (FIG. 5). In Fig. 6, that is, in the shading position, when the lamellae 3 are arranged approximately at an angle of 45 ° to the horizontal, the inner cable 7 is guided by the turning device 11 upwards, without the first spring 13 has been significantly stretched thereby , When pulling up the inner cable 7, the portion of the outer cable 5 is shortened between the lowest lying blade 3 and the deflection 17 and thus slightly shifted the position of the outer cable 5 to the vertical inward.
    In the closed position according to FIG. 7, the outer cable 5 and the inner cable 7 are approximately parallel to one another. The first spring 13 remains unstressed; the underlying second spring 19 is tensioned. As a result of the force F of a wind impinging on the curtain 1 from outside, the lamellae 3 are pressed into the horizontal and the uppermost first spring 13 is tensioned; the underlying second spring 19 relaxes slightly. Once the wind pressure or the force of the wind is eliminated on the slats 3, the slats 3 turn in turn in the vertical position or, if before the advent of the wind, the shading position has been present at 45 ° angle, back to this position.
    In the third embodiment of the invention according to FIGS. 9-11, the tensioning of the curtain 1 takes place between the turning device 11 and the lower soffit 9 through a connection 21, that is to say a fastening element, on the one hand with the lower soffit 9 and on the other hand is connected to the lowest lying slat 3. The connection 21 on the blade 3 takes place in the center between the longitudinal edges, which also forms a pivot center, when the blades 3, as shown in Fig. 10, are pivoted into the closed position. The pivoting center may be an eyelet in the lamella 3, through which the connection 21, e.g. a wire or plastic rope or a metal rod is guided. In the closed position according to FIG. 10, the lamellae 3 can slightly overlap one another and lie touching one another along the edges. The outer cable 5 and the inner cable 7 are very close to each other and approximately parallel. The overhead first spring 13 is unstressed. Only when exposed to wind from the outside with the force F, the slats 3 are pivoted depending on the wind force to the horizontal, while the overhead first spring 13 tensioned. In the absence of wind power F, the tensioned spring 13 pulls the slats 3 back into the previously assumed vertical position. If it has been assumed that the shade has a 45 ° angle, return to this position.
    In the fourth embodiment of the invention according to FIGS. 12-16, the individual lamellae 3 are each divided at the attachment points of the outer cable 5 and the inner cable 7 in the longitudinal direction into sections and the two opposite end faces 3a and 3b of the sections connected by a spacer 23 torsionally rigid with each other. The spacers 23 have the shape of a "Z". The horizontally extending legs 23 ^ of the spacer 23 are connected to the edges of the slats 3. In the embodiment according to FIG. 12a, plates 23 are arranged at the ends of the legs 23 of the spacer, which plates are glued, riveted or otherwise connected to the end regions of the lamellae 3. Between the vertically extending leg 23 of the spacer 3 and the end faces of the adjacent sections of the slats 3 thereby creates a gap 27 on both sides, which allows an unhindered passage on the one hand of the outer cable 5 and on the other hand of the inner cable 7, when the slats 3 in the vertical position come lie (closing position according to Fig. 15b, 16a and 16b). The connections between the outer cable 5 and the inner cable 7 with the blade 3 takes place at the horizontally extending portions 23 of the spacer 23rd
    In Fig. 12b, the spacer 23 is shown in isolation with the two laterally arranged plates 25.
    In Fig. 12c, the position of the outer cable 5 and the inner cable 7 in pivoted lamella 3 is visible in a perspective view. If the lamella 3 is completely turned into a vertical position, as shown for example in FIGS. 15a and 15b, the two cables, namely the outer cable 7 and the inner cable 7, come to lie directly next to one another in parallel.
    In addition, the lamellae 3, as in FIGS. 12c, 13a and 13b and in FIGS. 14a-15b, may be Z-shaped along the edges in order to make the lamellae 3 stiffer in the longitudinal direction. The Z-shaped design of the blade 3 is only on the inside, that is, the inner cable 7, formed; on the outside of the outer cable 5, the edge of the slats 3 is folded by 180 °, so folded. This configuration of the edges of the slats 3 makes it possible to align the slats 3 in the closed state, as shown in FIGS. 15a and 15b, absolutely vertically, supported by the fact that the inner cable 7 and the outer cable 5 in principle come to lie next to each other. When wind occurs (see FIGS. 16a and 16b), the outer cable 5 passes through the inner cable 7, and the lamellae 3 can be moved clockwise, by the force of the wind along its lower edge, which is in communication with the outer cable 5, into the direction shown in FIG. Pan 16a and 16b shown.
    The schematic representation in Fig. 17a shows the upper portion of the curtain 1 with two blades 3 and the turning device 11 in the usual shading position. If the turning device 11 is rotated in the counterclockwise direction as shown in FIG. 17b, then the lamellae 3 reach a horizontal optimally translucent position and at the same time the outer rope 5 is tensioned and thus the curtain 1 is held securely against the influence of strong wind.
    Figs. 18a and 18b show a device 29 for shirring the curtain 1 for the purpose of cleaning the windows of a window from the outside. Because the curtain 1 according to the invention has no elevator belts or tie-downs, the fins 3 have to be grasped in a different way for cleaning and guided upwards after the connection 21 with the lower soffit 9 has been released. As a device 29 for shirring, a U-shaped trough 31 or two U-shaped bent rods or wires 33 by means of an elevator means, for example an elevator rope or a chain 35, temporarily pulled up and temporarily fixed there.
