Abstract

The slatted blind has multiple slats, which are interconnected and suspended such that the slats are horizontally or vertically pulled apart and pushed together or placed on top of each other by an actuation element. The slats are angularly adjusted while the slats are pulled apart. The slats are made of a carbon-fiber composite material.

Description

Die Erfindung bezieht sich auf Lamellenstore, bestehend aus mehreren horizontal verlaufenden Lamellen, die durch Schnüre oder Bänder derart miteinander verbunden und an einer Aufziehwelle aufgehängt sind, dass die Lamellen durch Betätigung eines Zugelements gehoben oder gesenkt werden können und in abgesenktem Zustand außerdem winklig verstellbar sind.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.

Solche Lamellenstore werden vor Fenstern oder Glasfronten von Gebäuden angebracht, um Räume gegen einfallendes Streu- oder Direktlicht mehr oder weniger abzuschirmen und/oder zu beschatten; außerdem dienen sie als Sichtschutz.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.

Heutzutage bestehen diese Lamellen aus Aluminium. Mit diesem Material sind der Anwendung aus Stabilitätsgründen aber Grenzen gesetzt. Es lassen sich Lamellenstore aus Aluminum nur mit maximal 12 m2 Fläche herstellen und dies nicht nur bei Lamellen mit einfach konvex gewölbtem Profil, sondern auch bei denen mit dem hinsichtlich Stabilität schon besser bewährten, sogenannten Z-Profil. Vor allem bei Gebäuden mit großen Glas- oder Fensterfronten wird dies als nachteilig angesehen. Außerdem treten häufig schon bei der Anlieferung oder bei der Verarbeitung Schäden an den Aluminium-Lamellen auf, und zwar auch bei Lamellenstoren mit kleineren Abmessungen als die als maximal möglich angesehenen, indem die Lamellen z.B. verbogen werden oder sich verhaken oder verbiegen und damit unbrauchbar werden, denn das Aluminium besitzt keine Rückstellfähigkeit nach einer Verformung. Wenn die Lamellenstore an der Außenseite einer Fenster- oder Glasfront angebracht sind, was häufig geschieht, sind sie Wind und Wetter ausgesetzt; es ist vorgekommen, dass die Lamellen durch starken Wind aus der Führung gerissen und/oder verbogen und plastisch, also nicht rückstellbar, verformt wurden, auch Hagelschäden sind aufgetreten.Nowadays, these fins are made of aluminum. For reasons of stability, however, 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. In addition, 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. If the slatted blinds are attached to the outside of a window or glass front, which often happens, they are exposed to wind and weather; It has happened that the slats were torn by strong wind from the guide and / or bent and plastically, so not recoverable, were deformed, hail damage has occurred.

Aufgabe der Erfindung ist es, die Herstellung von Lamellenstoren mit größerer Stabilität und geringerer Anfälligkeit für Beschädigungen durch Wind und Wetter oder andere äußere Krafteinwirkungen zu ermöglichen. Vor allem für Gebäude mit großen Fenster- oder Glasfronten oder für das aufwendige Bauen allgemein, sind Lamellenstore mit einer größeren Quadratmeterfläche als die derzeit mit Aluminium-Lamellen möglichen 12m2 erwünscht; auch dies soll durch die größere Stabilität der neuen Lamellenstore ermöglicht werden.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.

Erfindungsgemäß wird dies dadurch erreicht, dass die Lamellen aus einem Carbonfaser-Verbundwerkstoff hergestellt sind.According to the invention this is achieved in that the lamellae are made of a carbon fiber composite material.

Eine Carbonfaserstruktur wird dazu in einem an sich bekannten 2-Komponentenharz getränkt und in einer dem gewünschten Lamellen-Profil entsprechenden Form gebacken.A carbon fiber structure is soaked in a known 2-component resin and baked in a shape corresponding to the desired lamellar profile.

Die Carbonfaserstruktur kann bevorzugt eine Gitternetzstruktur oder nach einer anderen Ausführungsform der Erfindung eine Längsfaserstruktur sein. Andere Faserstrukturen sind ebenfalls möglich, es ist jede erdenkliche Faserstruktur einsetzbar, ohne vom eigentlichen Erfindungsgedanken abzuweichen.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.

Carbonfaser-Verbundwerkstoffe weisen im Vergleich zu dem derzeit verwendeten Aluminium eine erheblich höhere Stabilität auf und erlauben dadurch die Herstellung von Lamellenstoren, die ca. 4 mal breiter sind als die bekannten Aluminium-Lamellenstore; dabei wirkt sich zusätzlich vorteilhaft aus, dass ein Carbonfaser-Verbundwerkstoff ein ca. 6 mal geringeres Gewicht als Aluminium hat, was z.B. die Verarbeitung mit großen Flächen sehr erleichtert. Carbonfaser-Verbundwerkstoffe sind elastisch verformbar und damit nach einer eventuellen, unbeabsichtigten Verformung, z.B. bei der Verarbeitung oder durch Witterungseinflüsse, rückstellfähig. Es treten also an den erfindungsgemäßen Lamellenstoren deutlich weniger oder keine, nicht rückgängig zu machende Schäden bei der Anlieferung, bei der Verarbeitung und Anbringung und schließlich auch im installierten Zustand auf. Es entsteht weniger oder kaum noch Ausschuss.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.

Durch die Auswahl der Carbonfaserstruktur lassen sich vorteilhaft bestimmte, gewünschte oder geforderte Eigenschaften der Lamellen beeinflussen und vorher bestimmen. Mit einer Gitternetzstruktur lässt sich z.B. die Stabilität der Lamellen deutlich erhöhen; die Lamellen können durch die richtige Wahl der Faserstruktur auch beschusssicher gemacht werden, was z.B. bei bestimmten öffentlichen Gebäuden oder Banken gefordert sein kann. Mit einer Längsfaserstruktur lässt sich die Elastizität und Rückstellfähigkeit der Lamellen erhöhen. Auch ästhetische Effekte, z.B. Facetten oder Katzenaugeneffekt und andere, lassen sich durch die Wahl der Faserstruktur erzielen, was besonders bei einer aufwendigen Bauweise als zusätzlicher Vorteil geschätzt wird.By selecting the carbon fiber structure, it is advantageously possible to influence and to predetermine certain, desired or required properties of the lamellae. With 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.
