    The device for stabilizing slat blinds comprises a plurality of slats (1) made of metal, which are supported at their front ends in guide rails and can be guided up and down by means arranged in the guide rails drive means and pivoted. In order to avoid sagging of the slats (1) arranged freely between the guide rails, connections (15) connecting the slats (1) are arranged, which, controlled by a support device, follow the turning movement of the slats (1). The connections (15) are not fastened to the slats (1) but to stabilizing elements (11) which are inserted between the longitudinal edges and project beyond the longitudinal edges of the slats (1).

    The invention relates to a device for stabilizing slat blinds according to the preamble of patent claim 1 and a slat blind according to claim 6.
    The term "all-metal blinds" lamellar blinds are known in which the slats are not suspended on elevator and reversing belts made of non-metallic materials, but whose two ends are held and carried exclusively in vertical guide rails. At the same time, the vertical displacement and the turning of the individual slats are effected by a corresponding mechanism made of metal in the guide rails. The advantage of this type of blind is the fact that on the upper or outer side, i. on the side facing away from the building, both in the open state and when closed, no vertical ropes or bands are visible. Another advantage of this Storenart is that in most cases more stable lamellae than the other sturgeons are used, which have little slack and at the same time provide quite high protection against burglary on the one hand and on the other hand against damage caused by high wind speeds in storm.
    However, such self-supporting lamellae have the disadvantage that their length, that is, the horizontal width of such disturbances is severely limited, as even with stable lamellae by their own weight and the elasticity of the material, usually aluminum, a slack can not be avoided , A slack of lamellae is quite well visible to the naked eye. If a store remains in a closed or semi-closed position for a long time, plastic deformation can occur as a result of the continuous deflection, and the lamellae can subsequently no longer be used in the desired manner.
    The length of the slats or the width of Ganzmetallstoren for windows or doors is currently at about 2.8 m. This limited width results from the still tolerable slack, that is a slack of the slats, which is hardly recognized by the naked eye. In modern buildings, where all facades consist more or less of window and door openings, therefore, the all-metal blinds can not be used or only limited or, if they are used, they interrupt the aesthetics of the facade in particular in a horizontal orientation by many short sections , The mechanism for pulling up and turning the individual slats is arranged in lateral guide rails. This mechanism is not described here in detail because it has been known for years in GRIESSER products and in the state of the art.
    From DE 2 212 894 a Rafflamellenjalousie with wearing and reversing straps is known in which a fastener in the form of a fastening clip between the Rollbördeln on the underside of the blade is used for the Wendeschnüre or Wendeschnur pairs. The mounting bracket has at the ends of eyelets, can be suspended by the loops, which are formed on the reversing straps. The loops partially wrap around the roll flanges of the slats.
    From CH 523 419 a similar arrangement as known from DE 2 212 894 is known, in which also the loops leading away from the reversing straps partially wrap around the roller crimp. By the fastening clips in these known documents stabilization and extended guidance of the turning tapes or cords can not be achieved.
    Furthermore, from US 2002/0 050 326 a clip is known, which comprises the lamellae on both sides, that is, both on the bottom and on the top of the lamella comes to rest and the lamellar edges projecting laterally. The sections of the clip projecting beyond the lamellar edges contain an eyelet for passing and fastening the turning tapes. With the blind closed, when the louvers are substantially vertical, the outer turning tapes also do not extend in an extended position, and thus non-linearly, pressing against the surface of the louvers.
    An object of the present invention is therefore to provide a device for 'stabilization of slats on slats blinds, which may have a working width, which is achieved with known slat blinds, in which the slats in short lateral distances on elevator belts and turning belts or Ropes are suspended and are repeatedly worn by these between the side mounted guide rails. Another object of the invention is to provide a device in which the connections between the slats in each slat position run linearly and substantially allows a gap-free abutment of the edges of the adjacent slats with the store closed.
    This object is achieved by a device according to the features of claim 1. Advantageous embodiments of the device are described in the dependent claims.
    It is possible to completely eliminate on the one hand the slack with vertical connections between the stabilizing elements and on the other hand, in a further embodiment, the flatness of the surfaces of the slats between the stabilizing elements connected to the slats at the bottom or top and associated with adjacent lamellae Both ends, which are guided and carried in the guide rails to maintain in each slat position. In other words, the torsional forces acting on the slats during the inclination, starting from the turning mechanisms in the guide rails, are thereby canceled.
    Due to the relocation of the building exterior to the lamellae lying next attachment points of the compound spaced from the lamellar edge can be achieved that the connections between the lamellae in each pivot position coaxial and do not rest on the surface of the slats and are deflected. In addition, it can be achieved by this measure that in each slat position, the slats worn by the compounds evenly and thus the slats come to rest in the horizontal absolutely linear and without sag.
    This arrangement of the connections on the outside makes it possible to mount the store as usual with all-metal blinds on site and to attach the compounds after installation on the building.
    Also on the building inside edges of the slats, the compounds are spaced from the edges, since the stabilizing elements extend beyond the edge region and thus lead the connections spaced.
    Reference to an illustrated embodiment, the invention will be explained in more detail. Show it:<Tb> FIG. 1 <SEP> a section of a lamella gate with two lamellae suspended on links in the open position,<Tb> FIG. 1 <SEP> a section of a lamella gate with two lamellae suspended on links in the closed position,<Tb> FIG. 1c <SEP> a fin section with a stabilizing element arranged linearly below it in the concave area,<Tb> FIG. 2a <SEP> two lamella sections in stacked position, view from outside,<Tb> FIG. 2b <SEP> two lamellar sections in stacked position, top view,<Tb> FIG. 2c <SEP> two slats cut vertically, stacked slats in cross section,<Tb> FIG. 2d <SEP> is a partial view of the outer lamella edges with these superior stabilizing elements,<Tb> FIG. 2e <SEP> an enlarged view of the bracket on the stabilizing elements and<Tb> FIG. 3 <SEP> is a perspective view of a stabilizing element.
    The figures each show only a short horizontal section of two slats 1. A slat blind of the genus discussed here may - depending on the height of the window or door opening - include an approximately any number of parallel superimposed slats 1. The number depends on the width of the slats 1 and the height of the wall opening. The guide rails arranged laterally on the windows or doors are not shown.
    The connection of the slats 1 with the mechanism in the laterally arranged guide rails is effected by attached to the ends of the slats 1, e.g. peg-shaped guide elements over which the mechanics of the vertical displacement of the slats 1 takes place and also the turning of the slats 1 about their longitudinal axes. It is also characterized by the fact that each lamella 1 is carried and guided at both front ends in the guide rails. Both the vertical transport of the slats 1 and their turns is transmitted synchronously and without play on the two ends.
    From the figures it can be seen that the cross-sectional shape of the slats 1 in the illustrated embodiment is substantially a trapezoidal shape, in which the two short planar legs 3.4 are at an acute angle to each other. The two legs 3, 4 are connected to one another at the top by a cover surface 5. The top surface 5 is arcuate in the example, but it can also be designed plan (no Fig.) And connects to the two legs 3 substantially sharp-edged or with a material-specific radius necessary. The two lower ends of the two legs 3,4 are formed differently. The outside in the open position of the store, that is, away from the building lying to lying outer edges 8 of the leg 3 form an obliquely downwardly directed Rollbördel 9, that is, the rolled edge comes to lie down. The on the inside, that is directed against the building interior legs 4 have a running at an obtuse angle to the leg 3 section 7. Also, the edge 10 of the section 7 is also crimped down, that is rolled up or folded. Of course, the cross-sectional shape of the lamellae 1 could also differ from that described here and, for example, have reinforcing beads extending in the longitudinal direction of the lamellae 1 or lamellae 1 as known from the prior art and having a wave shape (not shown). ,
    Either on the concave side of the slats 1, that is, on the lower side between the two legs 3, 4, which is aligned in the closed state of the store according to FIG. 1b on the building, or on the convex side, which lies outside in the closed state of the store, a stabilizing element 11 is placed on the blade 1 and connected thereto. Depending on the length of the slats 1, which corresponds to the width of a window or a door, a single or several such band-shaped stabilizing elements 11 are arranged at regular intervals on the slats 1.
    The cross-sectional shape in the longitudinal direction of the bow-like, made of strip steel or the like. Stabilizing elements 11 corresponds in their central portion of those of the slats 1. The stabilizing elements 11 are therefore in the central portion with their outer surfaces on the inner surfaces of the slats 1 or - if outside mounted - with their inner surfaces on the outer surface of the slats 1 at. At the end regions of the first and second legs 3, 4 of the stabilizing elements 11, which extend at an acute angle, different fastening elements 13, 14 for wire, rope or chain-shaped connections 15 to adjacent lamellae 1 or to stabilizing elements 11 on the adjacent lamellae 1 are formed , The fastening element 13 on the outside of the stabilizing element 11, i. the coming of the building away side includes, following the end of the leg 3 an obliquely downward or horizontally extending portion 16, to which an obliquely upward extending first tab 17 connects. Their end is designed as a roll bead 19. In the central region A of the roller crimp 19 is cut out, so that two spaced coaxial tubing 19 formed by the roller crimp 19 are visible (Fig. 2e). The two free ends of a T-element 21 engage in the small tubes 19 formed by the cut-off roll bead 19. The connection between the first tab 17 and the T-element 21 is thus articulated. The T-element 21 forms the connection to the flexible connection 15 and lies in or higher than the top surface 5 of the lamella 1. The connections 15 can be made of wire ropes, chains or also of aramid rope and the like.
    On the Rollbördel 19 opposite end portion of the stabilizing element 11, a second tab 22 is formed as a substantially horizontally extending portion 7 at the lower edge of the second leg 4, which is longer than the corresponding portion 7 on the lamella. 1 The end of the section 7A on the stabilizing element 11 is folded over in a flattened manner. There are also two coaxial tubes 20 are formed, the function and training the tubes 19 on the opposite side are the same or similar. Also in these two tubes 20, a T-element 21 is used, which forms the connection to the connection 15. As an alternative to tube 19 20 could also be provided on the tabs 17 attachable fasteners made of metal or plastic, which act as connections to the compounds 15 and 1511 (no Fig.).
    The attachment of the stabilizing element 11 to the blade 1 is effected by mutual entanglement along the lower edges of the legs 3 and 4 with the two flanges on the blade edges. At the stabilizing element 11 is at the root of the tab 17, a tongue 23 is formed, which has been generated for example by a punching and bending operation of the tab 17. At the opposite leg 4 are laterally or centrally also tongues 23 are arranged laterally of the centrally disposed roll bead 24 which engage when plugging the stabilizing element 11 into the interior of the roll bead on the blade edges 1 and engage under this and thereby lock the stabilizing element 11 in place ,
    The stabilizing elements 11 take the forces of the connecting elements, short connections 15, which connect the inner leg 4 and the outer leg 3 of the slats 1 adjacent slats 1 together. The slats 1 are therefore no longer punctually loaded at the edges. The connection of the connections 15 to the stabilizing elements 11 via the hinged connections such as the T-elements 21. Both compounds 15 are attached at their upper ends above the uppermost slat 1 in a support device 25 and can in the circumference of the path of the edges of Slats 1 when turning from the open to the closed position and vice versa by this raised or lowered. This to follow the pivoting of the slats 1, synchronously with the pivoting mechanism in the guide rails. The structure of the support device 25 and the turning device 17, which are preferably housed in a parallel to the slats 1 extending profile housing 19 is not explained in detail here. They are preferably connected to each other by a shaft.
    The operation of the device will be explained below. In the open position according to FIG. 1 a, the substantially horizontally oriented slats 1 are supported in the central area by both connections 15 in addition to the end-side mounting in the lateral guide rails (not shown). The joints 15 thus prevent any natural deflection of the slats. 1
    If the slats 1 are now pivoted by the mechanism in the lateral guide rails about a horizontal axis, for example in the closed position according to FIG. 1b, the inner connection 15 is stretched spaced at right angles to the lower edges of the legs 4, which now are aligned towards the building. The connections 15 are not visible from the outside. The outer links 15 are also stretched, i. linear over the top surfaces 5, since they are held by the tabs 17, which form the end portions, spaced from the longitudinal edges of the fins 1 and the top surface 5. From Fig. 1b it can be seen that the tabs 17 are dimensioned such that the compounds 15 are rectilinear and coaxial and thus exert no contact with the top surface 5 and no lateral forces on the slats 1 and consequently contamination of the fin surfaces can be avoided ,
    If, for architectural or other reasons, the stabilizing elements 11 are made visible to the viewer, they are plugged onto the convex side of the slats 1. For this purpose, the tongues 23 would have to be formed accordingly (not shown).<Tb> 1 <September> lamella<Tb> 3 <September> leg<Tb> 5 <September> Deck area<Tb> 7 <September> section<tb> 8 <SEP> outer edges<Tb> 9 <September> Flare<tb> 10 <SEP> inner edges<Tb> 11 <September> stabilizing element<Tb> 13 <September> fastener<Tb> 15 <September> Connection<Tb> 16 <September> section<tb> 17 <SEP> first tab<Tb> 19 <September> curled edge<Tb> 20 <September> Tubes<Tb> 21 <September> T-element<tb> 22 <SEP> second tab<Tb> 23 <September> tongue<Tb> 24 <September> curled edge<Tb> 25 <September> carrying device
