Abstract
Description
Die Erfindung betrifft ein Haftverschlussteil umfassend eine eine Trägerfläche festlegende Funktionslage, gebildet aus einem Fadensystem mit mindestens zwei miteinander verbundenen und Maschen bildenden Linienelementen, mindestens eine einzelne gebildete und/oder bildbare Verbindungselemente aufweisende weitere Funktionslage, gebildet aus einem zumindest bereichsweise in das Fadensystem eingebundenen Fadensystem.The invention relates to an adhesive closure part comprising a functional layer defining a carrier surface, formed from a thread system with at least two interconnected and mesh forming line elements, at least one individual formed and / or formable connecting elements having further functional position, formed from an at least partially integrated into the thread system thread system.
Derartige Haftverschlussteile werden in unterschiedlichsten Bereichen insbesondere in Befestigungssystemen, beispielsweise an Kleidungsstücken, Gepäckstücken, Möbelstücken, Verkleidungen im Fahrzeuginnenraum usw. eingesetzt und sind dementsprechend in unterschiedlichsten Ausführungen bekannt. Typischerweise ist das Haftverschlussteil ein textiler Flächenhaftverschluss mit pilzförmigen Verhakungselementen und in der Regel aus einem Kunststoffmaterial gefertigt. An einer den Verbindungselementen abgewandten Rückseite kann das Haftverschlussteil eine Beschichtung, beispielsweise eine Klebeschicht, aufweisen.Such adhesive closure parts are used in a wide variety of areas, in particular in fastening systems, for example on garments, pieces of luggage, pieces of furniture, panels in the vehicle interior, etc., and are therefore known in a wide variety of designs. Typically, the adhesive closure part is a textile surface fastener with mushroom-shaped interlocking elements and usually made of a plastic material. On a rear side facing away from the connecting elements, the adhesive closure part may have a coating, for example an adhesive layer.
Eine weitere Anwendung eines Haftverschlussteils ist die Verbindung bzw. Befestigung eines Schleifkörpers an einem Schleifmittelhalter. Aus
Ein hierbei eingesetzter Adapter besteht aus einer Klettadaptionsschicht, einer Schaumpartikelschicht und einer Veloursschicht, wobei die zum Schleifkörper hin weisende Klettadaptionsschicht von der Perforation durchdrungen ist. Eine typischerweise kreisrunde Schleifscheibe weist auf ihrer Rückseite ein Velours zum Ankletten an die Schleifplatte auf. Durch die entsprechende Anordnung der Durchbrechung der Perforation zueinander sowie gegenüber den Absaugeinrichtungen des Schleiftellers ist ein nahezu stauloser Transport des Schleifstaubes zu den Absaugeinrichtungen bewirkt.An adapter used in this case consists of a Velcro adaptation layer, a foam particle layer and a velor layer, wherein the Velcro adaptation layer facing the abrasive body is penetrated by the perforation. A typical circular grinding wheel has on its back a velor for Ankletten to the grinding plate. By the appropriate arrangement of the perforation of the perforation to each other and with respect to the suction of the sanding plate a nearly stauzy transport of the grinding dust is effected to the suction devices.
Ausgehend von diesem Stand der Technik stellt sich die Erfindung die Aufgabe, ein Haftverschlussteil bereitzustellen, welches einen einfachen Aufbau aufweist, insbesondere in einfacher Weise herstellbar ist, und zur Befestigung eines Schleifkörpers an einem Schleifmittelhalter eingesetzt werden kann, ohne den Schleifvorgang zu behindern.Starting from this prior art, the invention has the object to provide an adhesive closure part, which has a simple construction, in particular can be produced in a simple manner, and can be used to attach an abrasive article to an abrasive holder, without hindering the grinding process.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Haftverschlussteil mit den Merkmalen des Patenanspruchs 1 in seiner Gesamtheit. Dadurch, dass die Fadensysteme unter Bildung von Durchlassstellen miteinander verbunden sind, deren freie Querschnittsfläche mehr als 20% der entsprechenden Trägerfläche einnimmt, kann an der Anlage- bzw. Befestigungsfläche der vom Schleifkörper abgesaugte Schleifstaub durch das Haftverschlussteil weitestgehend ungehindert hindurchtreten. Das erfindungsgemäße Haftverschlussteil bietet insbesondere den Vorteil, dass bei Befestigung eines Schleifkörpers am Schleifmittelhalter keine besondere Ausrichtung des Haftverschlussteils in Bezug auf den Schleifkörper bzw. den Schleifmittelhalter gewählt werden muss, da das Haftverschlussteil über seine gesamte Fläche, genauer im Bereich der weiteren Funktionslage, staubdurchlässig ausgebildet ist.This object is achieved by an adhesive fastener with the features of claim 1 in its entirety. The fact that the thread systems are connected to form passage points whose free cross-sectional area occupies more than 20% of the corresponding support surface, can at the investment or mounting surface the abrasive dust extracted by the abrasive body passes through the adhesive closure part largely unhindered. In particular, the adhesive closure part according to the invention offers the advantage that when attaching an abrasive article to the abrasive article holder, no special alignment of the adhesive closure element with respect to the abrasive article or abrasive article holder has to be selected since the adhesive closure element is dust-permeable over its entire surface, more precisely in the region of the further functional layer is.
Der Einsatz des erfindungsgemäßen Haftverschlussteils beschränkt sich nicht auf den Bereich von Schleifkörpern, sondern erstreckt sich auf jeden Bereich, in welchem ein Fluiddurchtritt an einer Befestigungsfläche erwünscht und/oder zwingend ist. Vorstellbar ist beispielsweise die Befestigung eines zur Abwasser- oder Abluftreinigung eingesetzten Siebes in einem fluiddurchströmten Bereich oder eines in einer hydraulischen Anlage eingesetzten Filterelements. Auch ein Einsatz im Bereich atmungsaktiver Textilien, welche unter anderem im medizinischen oder pflegerischen Bereich eingesetzt werden, ist denkbar.The use of the adhesive closure part according to the invention is not restricted to the area of abrasive bodies, but extends to any area in which a fluid passage on a fastening surface is desired and / or compulsory. It is conceivable, for example, the attachment of a sieve used for sewage or exhaust air purification in a fluid-flow area or a filter element used in a hydraulic system. A use in the field of breathable textiles, which are used, inter alia, in the medical or nursing area, is conceivable.
In einer bevorzugten Ausführungsform des erfindungsgemäßen Haftverschlussteils umfasst zumindest ein eine Funktionslage bildendes Fadensystem eine Reihenanordnung von mindestens zwei in eine Längsrichtung verlaufenden, zueinander benachbarten Linienelementen, wobei die Linienelemente jeweils eine Folge von im Wesentlichen gleichartigen, in eine Querrichtung gerichteten Maschen bilden und in Längsrichtung versatzfrei zueinander angeordnet sind, und wobei eine oder mehrere Maschen zumindest eines Linienelements die entsprechenden Maschen des jeweils benachbarten Linienelements durch- bzw. umgreifen und somit miteinander verbinden. Hieraus ergibt sich der Vorteil eines formstabilen, in einfacher Weise herzustellenden Haftverschlussteils und insbesondere eine stabile, belastbare Trägerfläche. Die Maschen der einzelnen Linienelemente können mäanderförmig ausgebildet sein und jeweils eine rechteckförmige Kontur aufweisen. Alternativ können die Maschen schlaufen- bzw. schlingenartig ausgebildet sein und eine ellipsen- bzw. kreisförmige Kontur aufweisen.In a preferred embodiment of the adhesive closure part according to the invention, at least one thread system forming a functional layer comprises a series arrangement of at least two line elements extending in a longitudinal direction, wherein the line elements each form a sequence of substantially similar meshes oriented in a transverse direction and mutually offset in the longitudinal direction are arranged, and wherein one or more stitches at least one line element, the respective meshes of the respective adjacent line element by or surround and thus connect to each other. This results in the advantage of a dimensionally stable, easy to produce adhesive closure part and in particular a stable, load-bearing surface. The meshes of the individual line elements may be formed meander-shaped and each having a rectangular contour. Alternatively, the stitches may be loop-shaped or loop-shaped and have an elliptical or circular contour.
In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Haftverschlussteils umfasst das die weitere Funktionslage bildende Fadensystem mindestens ein in Längsrichtung verlaufendes Linienelement mit einer Folge von im Wesentlichen gleichartigen, in Querrichtung gerichteten Maschen, welche zumindest teilweise zur Bildung von Verbindungselementen auftrennbar und/oder aufgetrennt sind. Besonders bevorzugt verläuft das mindestens eine Linienelement der weiteren Funktionslage entlang eines entsprechenden Linienelements in der Trägerfläche und ist in entsprechender Weise mit (einem) benachbarten Linienelementen verbunden. Auf diese Weise kann das die weitere Funktionslage, typischerweise eine Verbindungslage, ausbildende weitere Fadensystem in einfacher Weise in das die Trägerlage bildende Fadensystem eingebunden werden. Ein dementsprechend gestaltetes Herstellungsverfahren lässt sich in einfacher Weise durchführen, insbesondere mit einer zur Bildung des Fadensystems geeigneten Webe- oder Wirkvorrichtung.In a further preferred embodiment of the adhesive closure part according to the invention, the thread system forming the further functional layer comprises at least one line element extending in the longitudinal direction with a series of substantially similar, transversely oriented stitches which are at least partially separable and / or split to form connecting elements. Particularly preferably, the at least one line element of the further functional layer runs along a corresponding line element in the carrier surface and is connected in a corresponding manner to (an) adjacent line elements. In this way, the further functional position, typically a connecting layer, forming further thread system can be integrated in a simple manner into the thread system forming the carrier layer. A correspondingly designed production method can be carried out in a simple manner, in particular with a weaving or knitting device suitable for the formation of the thread system.
Zweckmäßigerweise weisen die Maschen benachbarter Linienelemente in Längsrichtung die gleiche Erstreckung und/oder Reihenfolge auf. Auf diese Weise wird ein besonders sicherer und lagefester Verbund zwischen den Linienelementen geschaffen. Bevorzugterweise weist das die Trägerfläche bildende Fadensystem eine Reihenanordnung von sich abwechselnden ersten und zweiten Linienelementen auf, wobei die ersten Maschen der ersten Linienelemente in Querrichtung eine größere Erstreckung als die zweiten Maschen der zweiten Linienelemente aufweisen. In dieser Ausgestaltung des Haftverschlussteils entstehen vergleichsweise feste Verbindungsstellen an den Kreuzungsstellen zwischen Maschen benachbarter Linienelemente, wodurch die Maschenanordnung weitestgehend lagefixiert wird.Conveniently, the meshes of adjacent line elements in the longitudinal direction of the same extent and / or order. In this way, a particularly secure and stable connection between the line elements is created. Preferably, the thread system forming the carrier surface has a series arrangement of alternating first and second line elements, wherein the first stitches of the first line elements in the transverse direction have a greater extent than the second stitches of the second line elements. In this embodiment of the adhesive closure part, comparatively firm connection points arise at the intersections between meshes of adjacent line elements, whereby the mesh arrangement is largely fixed in position.
In einer bevorzugten Ausgestaltung weist das erfindungsgemäße Haftverschlussteil ein sich in Quer- und/oder Längsrichtung in regelmäßigen Abständen wiederholendes Muster mit im Wesentlichen gleichartig ausgebildeten und/oder angeordneten Linienelementen der Fadensysteme auf. Hieraus ergibt sich der Vorteil eines über die Funktionslagen bzw. die Trägerfläche homogenen Aufbaus und folglich homogener Eigenschaften des Haftverschlussteils, wie Formstabilität, Elastizität, Fluiddurchlässigkeit.In a preferred embodiment, the adhesive closure part according to the invention has a pattern which repeats in the transverse and / or longitudinal direction at regular intervals and has substantially identically constructed and / or arranged line elements of the thread systems. This results in the advantage of a homogeneous structure over the functional layers or the support surface and consequently homogeneous properties of the adhesive closure part, such as dimensional stability, elasticity, fluid permeability.
Zweckmäßigerweise ist die Funktionslage über die gesamte Trägerfläche mit dem weiteren Fadensystem verbunden, mit anderen Worten das Haftverschlussteil vollflächig in der erfindungsgemäßen Weise ausgebildet. Eine elastische bzw. flexible Ausgestaltung des Haftverschlussteils erlaubt dessen Anbringung als Dekorflächengebilde auf mitunter komplizierten 3D-Konturen zu deren Abdeckung. Das erfindungsgemäße Haftverschlussteil ist ein besonders weiches, dehnfähiges, offenporiges Flächengebilde. Die von dem Haftverschlussteil freigegebenen Durchlassöffnungen können parallelogrammartig, insbesondere rautenförmig oder rechteckförmig, und/oder polygonförmig, insbesondere hexagonförmig, ausgebildet sein. Auf diese Weise kann ein stabiler Funktionslagenverbund bei einer ausreichenden Formstabilität und Fluiddurchlässigkeit des Haftverschlussteils gewährleistet werden.Expediently, the functional layer is connected over the entire carrier surface with the further thread system, in other words the adhesive closure part is formed over its entire surface in the manner according to the invention. An elastic or flexible embodiment of the adhesive closure part allows its attachment as a decorative surface on sometimes complicated 3D contours to the cover. The adhesive closure part according to the invention is a particularly soft, extensible, open-pored fabric. The passage openings released by the adhesive closure part may be parallelogram-like, in particular diamond-shaped or rectangular, and / or polygonal-shaped, in particular hexagonal-shaped. In this way, a stable functional layer composite can be ensured with sufficient dimensional stability and fluid permeability of the adhesive closure part.
Vorteilhafterweise besteht das erfindungsgemäße Haftverschlussteil aus einem bevorzugt thermoplastischen Kunststoffmaterial, insbesondere Polyamid und bevorzugt isotaktischem Polypropylen. Besonders bevorzugt ist das Kunststoffmaterial recycelbar. Isotaktisches Polypropylen ist zur Ausbildung von Verhakungselementen mit Pilzköpfen besonders gut geeignet. Die Linienelemente der Fadensysteme sind typischerweise als Monofilamente, Multifilamente und/oder Garne ausgebildet. Diese können entsprechend einer gewünschten Anwendung eingefärbt sein.Advantageously, the adhesive closure part according to the invention consists of a preferably thermoplastic plastic material, in particular polyamide and preferably isotactic polypropylene. Particularly preferably, the plastic material is recyclable. Isotactic polypropylene is particularly well-suited for the formation of hooking elements with mushroom heads. The line elements of the thread systems are typically monofilaments, Multifilaments and / or yarns formed. These can be colored according to a desired application.
Die Verbindungselemente des erfindungsgemäßen Haftverschlussteils sind typischerweise pilzartig ausgebildet und weisen Verhakungsköpfe auf. Weiter ist es vorteilhaft, die Verbindungselemente auf einer Seite des Haftverschlussteils auszubilden. Somit steht eine von Verbindungselementen freie Rückseite des Haftverschlussteils als Verbindungsfläche mit einem Bauteil, wie einem Schleifmittelhalter, zur Verfügung. Bevorzugterweise wird dort eine Klebefläche aufgebracht. Es ist jedoch auch denkbar, an beiden Seiten, d.h., an Ober- und Unterseite des Haftverschlussteils jeweils eine weitere Funktionslage mit Verbindungselementen vorzusehen.The connecting elements of the adhesive closure part according to the invention are typically mushroom-shaped and have hooking heads. Further, it is advantageous to form the connecting elements on one side of the adhesive closure part. Thus, a connector-free rear side of the adhesive closure part is available as a connection surface with a component, such as an abrasive holder. Preferably, an adhesive surface is applied there. However, it is also conceivable to provide a further functional layer with connecting elements on both sides, that is to say on the upper and lower sides of the adhesive closure part.

Die zweiten Linienelemente 14a bis 14c weisen jeweils eine Aufeinanderfolge von zweiten Maschen 20a, 20a', 20a" des zweiten Linienelements 14a, zweite Maschen 20b, 20b', 20b" des zweiten Linienelements 14b, usw. auf. Die zweiten Maschen 20a bis 20b" sind jeweils gleichartig ausgebildet und, da die zweiten Linienelemente 14a bis 14c ohne Versatz in Längsrichtung 4 zueinander angeordnet sind, in Querrichtung 6 zueinander unmittelbar aufeinander folgend angeordnet. Die Verbindung bzw. Verwebung der ersten und zweiten Linienelemente 12a bis 12d, 14a bis 14c wird am Beispiel der zweiten Masche 20a näher erläutert: Die zweite Masche 20a durchgreift die erste Masche 16a des ersten Linienelements 12a und ist um die erste Masche 16b des benachbarten Linienelements 12b geführt, anders ausgedrückt ist die erste Masche 16b durch die zweite Masche 20a des zweiten Linienelements 14a durchgeführt. Durch die erste Masche 20a werden an zwei Verbindungsstellen 22a, 22b die benachbarten ersten Linienelemente 12a, 12b aneinander gebunden und in ihrer jeweiligen Lage stabilisiert. Zur Ausbildung entsprechend fester Verbindungsstellen 22a, 22b ist die Erstreckung der zweiten Masche 20a in Querrichtung 6 geringer als die entsprechende Erstreckung der ersten Maschen 16a und 16b.The
Die ersten Linienelemente 12a bis 12d sind jeweils aus einem Monofilament, die zweiten Linienelemente 14a bis 14d jeweils aus einem Multifilament gebildet. Die Fadendicke und die Maschenweite der ersten und zweiten Linienelemente 12a bis 12d, 14a bis 14c ist derart gewählt, dass freie Durchlassstellen 24a, 24b, 24c zwischen den ersten und zweiten Linienelementen 12a bis 12d, 14a bis 14c entstehen, wodurch das Fadensystem 10 bzw. die Funktionslage 2 fluiddurchlässig ist. Die freien Durchlass- bzw. Querschnittsflächen der Durchlassstellen 24a bis 24c stellen weit über 20% der Trägerfläche 8 dar bzw. nehmen diese ein.The
In
In den
Im gezeigten und beschriebenen Ausführungsbeispiel sind die dritten Linienelemente 26a bis 26c in Längs- und Querrichtung 4, 6 betrachtet an jeder zweiten dritten Masche zu Verbindungselementen aufgetrennt, so dass sich an diesen Stellen größere Durchlassstellen 24a im Vergleich zu Durchlassstellen 24b bei nicht durchgetrennten dritten Maschen einstellen. Weitere Durchlassstellen 24c und 24d sind durch die Anordnung der Linienelemente 12a bis 12d, 14a bis 14c, 26a bis 26c ausgebildet und bilden ein entsprechendes Muster aus. Somit ergibt sich ein in Querrichtung 6 nach einer Folge von zwei ersten Linienelementen 12a, 12b und zwei zweiten Linienelementen 14a, 14b wiederholende Folge und in Längsrichtung 4 nach zwei Maschen 16a, 16a' bzw. 20a, 20a' bzw. 28a, 28a' wiederholende Folge. Diese Mustereinheit wiederholt sich entlang der Trägerfläche 8 in Längs- und Querrichtung 4, 6 und ist sowohl auf der in den
Im gezeigten Beispiel ist für die dritten Linienelemente 26a bis 26c jeweils ein Monofilament, insbesondere aus isotaktischem Polypropylen, eingesetzt worden, es ist jedoch auch denkbar, einen eine Schleiffunktion sicherstellenden Werkstoff zur Ausbildung der dritten Linienelemente 26a bis 26c und insbesondere der Verbindungselemente 30a bis 30b" zu wählen. Die Verbindungselemente 30a bis 30b", wie in
Das vorstehend beschriebene, sehr luftdurchlässige Haftverschlussteil 32 lässt sich auch insbesondere im Kraftfahrzeugbereich einsetzen und bevorzugt im Bereich der Sitzteilpolsterung von Kraftfahrzeugen. Insbesondere ist das Haftverschlussteil 32 geeignet, Polstermaterialien des Fahrzeugsitzes nach außen hin abzudecken; dennoch besteht nach wie vor die Möglichkeit der Luftführung durch die insoweit offenen Maschen des Haftverschlussteils, was neben einer Sitzkomforterhöhung auch die Möglichkeit eröffnet, den Sitz entsprechend wirksam zu klimatisieren, d.h., eine Heiz- und/oder Kühlluftführung optimal zu verwirklichen. Das sich das Haftverschlussteil aufgrund seiner Verschlusselemente ohne weiteres von dem sonstigen Polsterbezug oder den Polstermaterialien lösen lässt, besteht auch insoweit eine Austauschmöglichkeit gegen ein entsprechend konzipiertes Neu-Haftverschlussteil.The above-described, very air-permeable
