Definitions

• the invention relates to slats, consisting of a plurality of horizontally extending slats, which are connected by cords or bands together and suspended from a Aufziehwelle that the slats can be raised or lowered by operating a tension member and are also angularly adjustable in the lowered state.
• Such slatted blinds are mounted in front of windows or glass fronts of buildings in order to more or less shield and / or shadow rooms from incidental or direct light; They also serve as privacy screens.
• these fins are made of aluminum.
• the application has limitations with this material.
• Aluminum slats can only be produced with a maximum surface area of 12 m 2 and this not only for slats with a simple convex curved profile but also for those with the so-called Z-profile, which has already proven itself in terms of stability. Especially for buildings with large glass or window fronts this is considered disadvantageous.
• damage to the aluminum slats often occur even at the time of delivery or during processing, even with slat blinds with smaller dimensions than the maximum considered possible, for example, by the slats are bent or get caught or bent and thus unusable, because the aluminum has no resilience after deformation.
• the object of the invention is to allow the production of slat blinds with greater stability and less susceptibility to damage from wind and weather or other external forces. Especially for buildings with large ones Window or glass fronts or for complex construction in general, slat blinds with a larger square footage than the currently possible with aluminum slats 12m 2 are desired; This is also to be made possible by the greater stability of the new lamellar store.
• the lamellae are made of a carbon fiber composite material.
• a carbon fiber structure is soaked in a known 2-component resin and baked in a shape corresponding to the desired lamellar profile.
• the carbon fiber structure may preferably be a lattice structure or, according to another embodiment of the invention, a longitudinal fiber structure.
• Other fiber structures are also possible, it is every conceivable fiber structure can be used without departing from the actual inventive idea.
• Carbon fiber composite materials have a significantly higher stability compared to the currently used aluminum and thus allow the production of lamella blinds, which are about 4 times wider than the known aluminum lamella blinds; In addition, it has the additional advantage that a carbon fiber composite material weighs about 6 times less than aluminum, which is, for example, the processing with large areas much easier. Carbon fiber composite materials are elastically deformable and thus after a possible, unintentional deformation, e.g. during processing or due to weather conditions, resilient. Thus, significantly less or no irreversible damage to the lamellar blinds according to the invention occurs during delivery, during processing and attachment, and finally also in the installed state. There is less or hardly any waste.
• the carbon fiber structure By selecting the carbon fiber structure, it is advantageously possible to influence and to predetermine certain, desired or required properties of the lamellae.
• a grid structure for example, the stability of the slats can be significantly increased;
• the lamellae can also be made bullet-proof by the right choice of fiber structure, which is the case for certain public buildings or banks may be required.
• With a longitudinal fiber structure the elasticity and resilience of the slats can be increased. Also, aesthetic effects, such as facets or cat's eye effect and others, can be achieved by choosing the fiber structure, which is particularly appreciated in an elaborate design as an additional advantage.
