Description
AKTENZEICHEN: Neuanmeldung Aufzugs- oder Tragorgane für Jalousien-Die Erfindung betrifft Aufzugs- oder Tragorgane für Jalousien, bestehend aus gewebtem, gewirktem oder geflochtenem textilem Material in Form von Bändern, Schnüren, Kordeln od. dgl.FILE NUMBER: New registration for elevator or support elements for blinds The invention relates to elevator or support members for blinds, consisting of woven, knitted or braided textile material in the form of ribbons, cords, cords or the like
Lamellenjalousien, insbesondere solche- mit besonders breiten, eingebördelten Lamellen, werden in zunehmendem Maße außen vor den Fenstern angebracht, deren Sonnenschutz die Jalousie übernehmen soll. Bei solchen Außen-Jalousien hat sich gezeigt, daß im Laufe der Zeit die aus textilem Material bestehenden Trag- und Aufzugsorgane verhärten und neben ihrer Flexibilität auch an Länge verlieren. Diese Verkürzung und Versprödung ist besonders maßlich bei den zumeist aus Kordel- oder Schnurmaterial bestehenden "Leitern", welche die Lamellen zwischen Leiterstegen tragen, aber a uch zum Wenden der Lamellen dienen.Louvre blinds, especially those with particularly wide, beaded Slats are increasingly being placed outside the windows to protect them from the sun the blind should take over. With such external blinds it has been shown that In the course of time, the lifting and lifting organs made of textile material harden and, in addition to their flexibility, also lose their length. This shortening and embrittlement is particularly significant in the case of those mostly made of cord or cord material existing "ladders", which carry the slats between ladder bars, but a They can also be used to turn the slats.
Man hat die Versteifung und Verkürzung der textilen Schnüre, Kordeln etc. bislang auf chemische Einflüsse (Versprödung und Schrumpfung synthetischen Fstermaterials) oder auf den Einfluß der bei Außenjalousien ungehindert einvirkenden Uv-Strahlung zurUckgeführt.One has the stiffening and shortening of the textile cords, cords etc. so far on chemical influences (Embrittlement and shrinkage synthetic window material) or on the influence of external blinds acting UV radiation.
Es wurde nun gefunden, daß tatsächlich die Verschnutzung der textilen Band-, Kordel- und Schnurwerkstoffe für die Verhärtung und Verkürzung verantwortlich ist. Die Schnüre, Kordeln und Bänder haben keine glatte Außenfläche, sondern umschließen viele kleine Hohlräume, in die von der Luft mitgeführte Staubpartikel od. dgls eindringen und durch normale Adhäsion - mitunter verstärkt durch elektrostatische Ladungen - festgehalten werden. Hinzu kommt, daß im Betrieb der Außenjalousie die Schnüre, Kordeln etc. abwethselnd gespannt und entlastet werden, so daß ein immer festeres Einpressen der Fremdkörper in die Kordeln, Schnüre etc. bewirkt wird.It has now been found that the wear and tear on the textile Tape, cord and cord materials are responsible for hardening and shortening is. The cords, cords and ribbons do not have a smooth outer surface, but enclose many small cavities into which airborne dust particles or the like penetrate and normal adhesion - sometimes aggravated by electrostatic charges - be held. In addition, when the external blind is in operation, the cords Cords etc. are alternately tensioned and relieved, so that an increasingly solid Pressing the foreign body into the cords, cords, etc. is effected.
Ausgehend von dieser Erkenntnis und der weiteren Überlegung, daß zur Vermeidung der oben dargelegtffin Nachteile das Eindringen von Fremdkörpern in das textile Material von vornherein verhindert werden sollte, besteht die Erfindung darin, daß das textile Material mit einem flüssigen Gleitmittel getränkt ist. Es hat sich geneigt, daß ein solches Gleitmittel - vorzugsweise ein nichtharzendes Öl wie Paraffinöl oder Silikonöl - nicht nur das Eindringen von Fremdkörpern in die feinen Hohlräume der Leiterkordeln, Aufzugsbärider und dgl. vechindert, sondern daß sogar durch eine nachträgliche Tränkung bereits Verschmutzte und dadurch versteifte sowie verkürzte Leiterkordelh etc. ein Herausspülen eingedrungener Fremdkörper erreicht wird. Das Gleitmittel hebt während der Belastung der Kordeln; Schnüre etc.Based on this knowledge and the further consideration that for Avoidance of the disadvantages outlined above, the ingress of foreign bodies into the textile material should be prevented from the outset, there is the invention in that the textile material is impregnated with a liquid lubricant. It has inclined that such a lubricant - preferably a non-resinous one Oil like paraffin oil or silicone oil - not just the ingress of foreign bodies in the fine cavities of the ladder cords, elevator bearers and the like that even after a subsequent impregnation, already soiled and thereby stiffened as well as shortened ladder cords etc. a flushing out of penetrated foreign bodies is achieved will. The lubricant lifts during the load on the cords; Cords etc.
beim Ablassen der Jalousien Reibungen im Innern des textilen Materials weitgehend auf und ermöglicht so das Ausstoßen der Fremdkörper. Es paßt sich ferner der jeweils unterschiedlichen Hohlraumgröße an, ohne die bestimmungsgemäße Wirkung der Schnüre, Kordeln, Bänder und dgl. zu beeinträchtigen; im Gegenteil, deren Geschmeidigkeit wird noch erhöht.When lowering the blinds, friction inside the textile material largely and thus enables the foreign bodies to be expelled. It also fits the each different cavity size, without the intended one To impair the effect of the cords, cords, ribbons and the like. on the contrary, their suppleness is increased.
