Mechanisches Haftverschlussteil Mechanical adhesive closure part
Die Erfindung betrifft ein mechanisches Haftverschlussteil, mit einem Trägerteil und einer Vielzahl von Haftelementen, die sich über Stiele vom Trägerteil weg erstrecken und an ihrem freien Ende jeweils mit einem Kopfteil versehen sind, wobei die Haftelemente auf dem Trägerteil in Gruppen un- terteilbar angeordnet sind, die eine fiktive Ringanordnung in Form eines Mehreckes mit von einem Haftelement besetzten Ecken bilden. The invention relates to a mechanical adhesive closure part, comprising a carrier part and a multiplicity of adhesive elements which extend away from the carrier part via stems and are each provided with a head part at their free end, the adhesive elements being arranged undetachably in groups on the carrier part, which form a fictitious ring arrangement in the form of a polygon with occupied by an adhesive element corners.
Derartige Haftverschlussteile sind Bestandteil von Haftverschlüssen, wie sie unter der Markenbezeichnung„Kletten" weithin bekannt geworden sind. Die mit ihren Stielen mit dem Trägerteil zusammenhängenden Haftelemente bilden mit ihren Kopfteilen Verschlusskörper, die vorzugsweise die Form von Pilzköpfen, jedoch auch von Haken oder Schlaufen, haben können. Dabei sind die Haftelemente mit Stiellängen, die häufig weniger als 1 mm betragen, in dichter Packung am Trägerteil derart verteilt angeordnet, dass die Verhakungskörper der Kopfteile in Verhakungseingriff mit den Gegenelementen eines den Haftversehl uss vervollständigenden weiteren Haftverschlussteiles kommen. Such fastener parts are part of adhesive closures, as they have become widely known under the brand name "burdock." The associated with their stems with the support member adhesive elements form with their head closure body, preferably in the form of mushroom heads, but also of hooks or loops have In this case, the adhesive elements with stem lengths, which are often less than 1 mm, arranged distributed in a dense packing on the support member such that the hooking body of the head parts come into hooking engagement with the counter-elements of the Haftversehl uss completing another adhesive closure part.
Eines der Kriterien für gute Gebrauchseigenschaften von Haftverschlüssen besteht darin, dass für die Betätigung des Verschlusses der Verhakungseingriff sicher und bequem erfolgen kann, selbst wenn in dem Bestreben, eine hohe Haltekraft des betätigten Verschlusses zur Verfügung zu stellen, die Haftelemente in sehr dichter Packung am Trägertei l angeordnet sind. Die Forderungen nach hoher Packungsdichte und nach einfacher Betätigbarkeit des Verschlusses mit geringem Kraftaufwand sind jedoch einander widerstrebend. One of the criteria for good use properties of adhesive closures is that the operation of the closure of the interlocking engagement can be safely and conveniently, even if in an effort to provide a high holding force of the operated closure, the Adhesive elements are arranged in a very dense packing on Trägertei l. However, the demands for high packing density and easy operability of the closure with little effort are mutually reluctant.
Wenn zur Verschlussbetätigung die Haftverschlussteile aneinandergelegt werden, besteht eine gewisse Wahrscheinlichkeit, dass Kopfteile auf Kopfteile fluchtend aufeinandertreffen. Um den Verhakungseingriff zu erreichen, muss eine Art Verdrängung, um Eingriffswege frei zu machen, erfolgen. Ins- besondere bei hoher Packungsdichte ist dadurch eine entsprechend hohe Betätigungskraft erforderlich. Werden hohe Betätigungskräfte in Kauf genommen, was bei bestimmten Anwendungsgebieten hingenommen werden kann, dann resultierenden vielfach im betätigten Zustand so hohe Haltekräfte, dass ein bequemes Lösen des betätigten Verschlusses erschwert oder verhindert ist. When the fastener parts are abutted together for the closure operation, there is a certain likelihood that head portions will be flush with each other on head portions. In order to achieve the interlocking intervention, a kind of repression must be done to clear intervention paths. In particular, at high packing density, a correspondingly high actuation force is required. If high operating forces are accepted, which can be tolerated in certain fields of application, then so many holding forces result in the actuated state that a comfortable release of the operated closure is difficult or prevented.
Im Hinblick auf diese Problematik ist es Stand der Technik, die Haftelemente am Trägerteil in einer von einer regelmäßigen Matrix abweichenden Musteranordnung vorzusehen. Diesbezüglich ist im Dokument DE 603 10 529 T2 ein Haftverschlussteil der eingangs genannten Art offenbart, bei dem die Haftelemente in Gruppen von jeweils vier Haftelementen angeordnet sind, wobei die Haftelemente jeder Gruppe an den Ecken eines nahezu quadratischen Rechtecks angeordnet sind. Ein gattungsgemäßes Haftverschlussteil ist aus der DE 94 12 526 U1 bekannt geworden. Das bekannte Haftversehl uss- bzw. Befestigungsteil weist eine Basis und mehrere mit Köpfen versehene, im Wesentlichen stiftförmige Verankerungselemente auf, die einander benachbart sind und von der Basis abstehen. Eine Gruppe von ersten Verankerungselementen ist an Positionen auf der Oberfläche der Basis derart angeordnet, dass sie die Eckpunkte von im Wesentlichen regelmäßigen hexagonalen Mustern bilden. Die Anord- nung der ersten Verankerungselemente wird durch ein Grundmuster bestimmt, das durch regelmäßige Sechsecke, die aneinander angrenzen und dabei eine Seite oder Ecke gemeinsam haben, oder durch konzentrische Kreise definiert. Weiter ist in jedem der polygonalen Muster an einer vom Mittelpunkt versetzten Position mindestens ein zweites Verankerungselement angeordnet. Auf diese Weise wird eine Befestigungsvorrichtung mit Verankerungselemente aufweisenden Befestigungsteilen geschaffen, die eine ausreichend hohe Rückhaltekraft auch in Scherrichtung aufweist. Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Haftverschlussteil zur Verfügung zu stellen, das sich durch besonders gute Gebrauchseigenschaften in Bezug auf die sichere und bequeme Betätigung mit geringem, für den Verhakungseingriff erforderlichem Kraftaufwand auszeichnet und bei dem die jeweils gewünschten Haltekräfte realisierbar sind. In view of this problem, it is state of the art to provide the adhesive elements on the carrier part in a pattern arrangement deviating from a regular matrix. In this regard, document DE 603 10 529 T2 discloses an adhesive fastener part of the type mentioned in the opening paragraph, in which the adhesive elements are arranged in groups of four adhesive elements each, wherein the adhesive elements of each group are arranged at the corners of a nearly square rectangle. A generic adhesive closure part has become known from DE 94 12 526 U1. The known Haftvershl uss- or fastening part has a base and a plurality of headed, substantially pin-shaped anchoring elements which are adjacent to each other and project from the base. A group of first anchoring elements is disposed at positions on the surface of the base so as to form the vertices of substantially regular hexagonal patterns. The arrangements The orientation of the first anchoring elements is determined by a basic pattern defined by regular hexagons which adjoin one another while sharing a side or corner, or by concentric circles. Furthermore, at least one second anchoring element is arranged in each of the polygonal patterns at a position offset from the center. In this way, a fastening device is provided with anchoring elements having fastening parts, which has a sufficiently high retention force in the shear direction. Based on this prior art, the present invention seeks to provide a fastener part available, which is characterized by particularly good performance in terms of safe and comfortable operation with low, required for Verhakungseingriff force and in which the respective desired holding forces are feasible.
Erfindungsgemäß ist diese Aufgabe durch ein Haftverschlussteil gelöst, das die Merkmale des Patentanspruches 1 in seiner Gesamtheit aufweist. Demgemäss sieht die Erfindung vor, dass innerhalb der Gruppen in Form einer mehreckigen Ringanordnung mit von Haftelementen besetzten Ecken jeweils eine Haftelementgruppierung gebildet ist, deren Kopfteile in nicht betätigtem Zustand des Haftverschlusses benachbart aneinander stoßen. Eine derartige Musteranordnung, in der sowohl Gruppierungen mit kopfsei- tig aneinanderstoßenden Haftelementen als auch„frei stehende" Haftelemente enthalten sind, ermöglicht einen optimalen Kompromiss zwischen erforderlicher Betätigungskraft und resultierender Haltekraft, insbesondere bei der anzustrebenden hohen Packungsdichte der Haftelemente. Gegenstand der Erfindung ist entsprechend dem Patentanspruch 2 auch ein Haftverschlussteil der eingangs genannten Gattung, bei dem die Haftele- mente am Trägerteil in einer Packungsdichte von zumindest 1507cm2 angeordnet sind. According to the invention, this object is achieved by an adhesive closure part having the features of claim 1 in its entirety. Accordingly, the invention provides that, within the groups in the form of a polygonal ring arrangement with corners occupied by adhesive elements, an adhesive element grouping is formed in each case, the head parts of which abut adjacent to one another in the non-actuated state of the adhesive closure. Such a pattern arrangement, in which both groupings with adhesive elements adhering to the top side and "free-standing" adhesive elements are contained, makes possible an optimum compromise between required actuating force and resultant holding force, in particular in the case of the high packing density of the adhesive elements Claim 2 also an adhesive closure part of the type mentioned, in which the adhesive are arranged on the support member in a packing density of at least 1507cm 2 .
Hinsichtlich der Gruppierungen mit kopfseitig aneinander stoßenden Haft- elementen kann die Anordnung so getroffen sein, dass Haftelementgruppierungen durch Haftelementpaare oder aus drei Haftelemente aufweisenden Triplets gebildet sind. With regard to the groupings with adhesive elements abutting on the head side, the arrangement may be such that adhesive element groups are formed by pairs of adhesive elements or by triplets having three adhesive elements.
Bei aus Haftelementpaaren gebildeten Gruppierungen kann jede Gruppe vorzugsweise zumindest sechs von einem Haftelement besetzte Ecken aufweisen, wobei in jeder Gruppe die Haftelemente zumindest zweier Ecken ein Haftelementpaar mit aneinander anliegenden Kopfteilen bilden. In groupings formed from adhesive element pairs, each group may preferably have at least six corners occupied by an adhesive element, wherein in each group the adhesive elements of at least two corners form an adhesive element pair with abutting head portions.
Bei bevorzugten Ausführungsbeispielen weisen die Haftelemente Kopfteile in Form von Pilzköpfen auf. In preferred embodiments, the adhesive elements have head portions in the form of mushroom heads.
Als Werkstoff für die Haftelemente ist vorzugsweise isotaktisches Polypropylen vorgesehen. Bei Ausführungsbeispielen mit Haftelementgruppierungen in Form von Haftelementpaaren ist die Anordnung vorzugsweise so getroffen, dass die Gruppen der Haftelemente ungleichseitige Sechsecke mit je zwei Haftelementgruppierungen mit an ihren Kopfteilen aneinander anliegenden Haftelementpaaren bilden. As the material for the adhesive elements isotactic polypropylene is preferably provided. In embodiments with adhesive element groupings in the form of adhesive element pairs, the arrangement is preferably such that the groups of adhesive elements form unequal hexagons each with two adhesive element groupings with adhesive element pairs adjacent to one another at their head parts.
Besonders gute Gebrauchseigenschaften lassen sich hierbei erzielen, wenn die zwischen den Haftelementpaaren der Gruppen gelegenen einzelnen Haftelemente voneinander einen größeren Abstand besitzen als von den jeweils benachbarten Haftelementpaaren. Entsprechend der im Dokument DE 102 40 986 B3 aufgezeigten Technik kann das Trägerteil aus Kett-, Schuss- und Polfäden, insbesondere in Form einer W-Bindung, ausgebildet sein. Dabei werden die über das Grundgewebe vorstehenden Schlaufen der Polfäden aufgeschnitten. Die so gebilde- ten Fadenenden werden thermisch behandelt, um Haftelemente mit Kopfteilen in Form von Verhakungskörpern, insbesondere in Pilzkopfform, zu bilden. Particularly good performance characteristics can be achieved in this case when the individual adhesive elements located between the adhesive element pairs of the groups have a greater distance from one another than from the respective adjacent adhesive element pairs. According to the technique disclosed in DE 102 40 986 B3, the carrier part can be formed from warp, weft and pile threads, in particular in the form of a W-bond. In the process, the loops of the pile threads projecting beyond the base fabric are cut open. The yarn ends formed in this way are thermally treated in order to form adhesive elements with head parts in the form of hooking bodies, in particular in mushroom head form.
Die Anordnung kann mit Vorteil so getroffen sein, dass die Kett- und Schussfäden Multifilamente sind und dass der vorzugsweise als Monofila- ment ausgebildete Polfaden einen Durchmesser von etwa 0,20mm aufweist. The arrangement may advantageously be such that the warp and weft threads are multifilaments and that the pile thread, which is preferably designed as a monofilament, has a diameter of approximately 0.20 mm.
Bei besonders vorteilhaften Ausführungsbeispielen weisen die Kettfäden und Schussfäden 200 bzw. 1 10dtex auf, wobei die Schussdichte für die Schussfäden bei etwa 23 Schuss/cm liegt. In particularly advantageous embodiments, the warp threads and weft threads 200 and 1 10dtex, wherein the weft density for the weft threads is about 23 rounds / cm.
Nachstehend ist die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen im Einzelnen erläutert. Es zeigen: The invention with reference to embodiments shown in the drawings will be explained in detail. Show it:

Fig. 3 eine schematisierte und stark vergrößerte Seitendarstellung auf eine Polbindung zur Herstellung des erfindungsgemäßen Haftverschlussteiles, wobei lediglich Pol- und Kettfäden ge- zeigt sind. Fig. 1 verdeutl icht die Musteranordnung der Haftelemente eines ersten Ausführungsbeispieles des erfindungsgemäßen Haftverschlussteiles. Von den Haftelementen sind in Fig. 1 durch Kreise lediglich die Kopfteile 2 darge- stellt, die an den Enden der nicht sichtbaren Stiele pilzkopfartige Verha- kungskörper bilden. Bei dem Beispiel von Fig. 1 lässt sich die Anordnung der Haftelemente in Gruppen 4 unterteilen, die eine Ringanordnung in Form eines ungleichseitigen Sechseckes darstellen, deren sechs Ecken jeweils vom Kopfteil 2 eines Haftelementes besetzt sind. Die Sechseckform weist zueinander entgegengesetzt zwei kürzere Seiten auf, wodurch die an den Ecken dieser kurzen Seiten befindlichen Kopfteile 2 aneinander stoßen. Somit sind innerhalb jeder Gruppe 4 zwei Haftelementgruppierungen gebildet, bestehend aus je einem Haftelementpaar 6. Von diesen Haftelementpaaren 6 sind der Übersichtlichkeit halber in Fig. 1 nicht sämtliche beziffert. Wie Fig. 1 verdeutlicht, ist eine Musteranordnung gebildet, bei der in der Folge von sich in der Fig. waagerecht erstreckenden Gruppen 4 sich Gruppierungen, die aus Haftelementpaaren 6 gebildet sind, mit einzelnen Kopfteilen 2 abwechseln, wobei die nicht zu Paaren 6 gehörenden Kopfteile 2 voneinander einen größeren Abstand besitzen als von den je- weils benachbarten Paaren 6. Wie sich gezeigt hat, bietet eine derartige Musteranordnung, bei der sich„frei stehende" Kopfteile 2 in der gezeigten Weise mit Gruppierungen abwechseln, die durch kopfseitig aneinander stoßende Haftelementpaare 6 gebildet sind, beste Verhältnisse hinsichtlich der Verschlussbetätigung durch Herbeiführen des Verhakungseingriffes mit verhältnismäßig geringem Kraftaufwand, und zwar trotz einer Anordnung der Haftelemente in hoher Packungsdichte von beispielsweise mehr als 150 Haftelementen pro cm2. Bei einer derartigen Musteranordnung sind auch die für die Gebrauchseigenschaften günstigen Haltekräfte realisierbar. Fig. 2 verdeutlicht ein anderes Ausführungsbeispiel, bei dem wiederum3 shows a schematic and greatly enlarged side view of a pile binding for the production of the adhesive closure part according to the invention, wherein only pile and warp threads are shown. 1 illustrates the pattern arrangement of the adhesive elements of a first exemplary embodiment of the adhesive closure part according to the invention. Of the adhesive elements, only the head parts 2 are represented by circles in FIG. 1, which form mushroom-like catching bodies at the ends of the invisible stems. In the example of Fig. 1, the arrangement of the adhesive elements can be divided into groups 4, which represent a ring assembly in the form of an irregular hexagon, whose six corners are each occupied by the head part 2 of an adhesive element. The hexagon shape has two shorter sides opposite to each other, whereby the head portions 2 located at the corners of these short sides abut each other. Thus, within each group 4, two adhesive element groupings are formed, each consisting of one adhesive element pair 6. For the sake of clarity, not all of these adhesive element pairs 6 are numbered in FIG. 1. As illustrated in FIG. 1, a pattern arrangement is formed in which, as a result of horizontally extending groups 4 in the figure, groupings formed from adhesive element pairs 6 alternate with individual head parts 2, the head parts not belonging to pairs 6 2 have a greater distance from each other than from the pairs 6 adjacent each other. As has been shown, such a pattern arrangement in which "free-standing" head parts 2 alternate with groupings in the manner shown offers the adhesive element pairs 6 striking one another on the head side Best conditions with respect to the shutter operation by inducing the Verhakungseingriffes with relatively little effort, despite an arrangement of the adhesive elements in high packing density, for example, more than 150 adhesive elements per cm 2. In such a pattern arrangement are also favorable for the performance characteristics holding forces Fig. 2 illustrates another embodiment in which again
Gruppen 4 eine Ringanordnung in Form eines ungleichseitigen Sechseckes definieren, dessen Ecken jeweils von einem Kopfteil 2 eines betreffenden Haftelementes besetzt sind. Bei der Rechteckform von Fig. 2 sind zwei lange Seiten einander gegenüberliegend, während zwischen den langen Seiten beidseits zwei kurze Seiten vorgesehen sind. Wiederum ist jede Ecke vom Kopfteil 2 eines Haftelementes besetzt. Entsprechend dem verringerten Abstand der Ecken an den vier kürzeren Seiten ist an den durch die langen Seiten getrennten drei Ecken jeweils eine Gruppierung in Form eines Triplets oder einer Dreiergruppe von Haftelementen gebildet, bei denen drei Kopfteile 2 in Aufeinanderfolge aneinander stoßen. Somit sind bei die- sem Ausführungsbeispiel abwechselnde Reihen 8 aus dicht gepackten Kopfteilen 2 gebildet, die mit Freiräume bildenden Reihen abwechseln. Je nach Wahl der Länge der zwei langen Seiten der Sechseckform und damit der Weite der zwischen den Reihen 8 gebildeten Freiräume lassen sich die Eigenschaften des Verschlusses hinsichtlich Haltekraft und Betätigungskraft optimieren. Groups 4 a ring arrangement in the form of an unequal hexagon define whose corners are each occupied by a head part 2 of a respective adhesive element. In the rectangular shape of Fig. 2, two long sides are opposed to each other, while two short sides are provided on both sides between the long sides. Again, each corner is occupied by the head part 2 of an adhesive element. Corresponding to the reduced spacing of the corners on the four shorter sides, a grouping in the form of a triplet or a group of three adhesive elements is formed at the three corners separated by the long sides, in which three head parts 2 abut in succession. Thus, in this embodiment, alternate rows 8 are formed of densely packed headers 2 which alternate with rows forming clearances. Depending on the choice of the length of the two long sides of the hexagonal shape and thus the width of the free spaces formed between the rows 8, the properties of the closure with respect to holding force and operating force can be optimized.
Fig. 3 verdeutl icht vom Grundgewebe eines die Haftelemente tragenden Trägerteiles 10 lediglich Kettfäden 12 (nicht sämtliche beziffert), versehen mit Polfäden 14 in Form einer W-Bindung, wobei die Polfäden 14 über das Grundgewebe vorstehende Schlaufen 16 bilden. Kett-, Schussfäden und Polfäden können aus einem isotaktischen Polypropylen gebildet sein, wobei Kett- und Schussfäden vorzugsweise Multifilamente sind, während der Polfaden 14 vorzugsweise als Monofilament ausgebildet ist und einen Durchmesser von etwa 0,20mm aufweist. Bei derartigen Werkstoffen lassen sich aus den Schlaufen 16 des Polfadens 14 Haftelemente mittels der aus DE 102 40 986 B3 bekannten Technik ausbilden. Wenn zur Bildung der Haftelemente die Schlaufen 16 durch einen thermischen Trenn- oder Schneidvorgang aufgeschnitten werden, können die freien Schlaufenenden durch weiteres Erhitzen zum Schrumpfen gebracht werden, wobei die En- den Verschlusskörper vorzugsweise pilzartiger Form oder auch Verschlusshaken bilden können. Bei Durchmessern des Polfadens 14 von etwa 0,20mm und bei Kettfäden und Schussfäden, die 200 bzw. 1 10dtex aufweisen, lassen sich Packungsdichten der gebildeten Haftelemente von mehr als 150/cm2 verwirklichen. Die Schussdichte für die in Fig. 3 nicht gezeigten Schussfäden kann im Bereich von 23/cm liegen. Fig. 3 shows not clarified by the base fabric of a carrier member carrying the adhesive elements 10 only warp threads 12 (not all quantified), provided with pile threads 14 in the form of a W-bond, the pile threads 14 form above the base fabric loops 16. Warp, weft and pile yarns may be formed from an isotactic polypropylene, with warp and weft yarns being preferably multifilaments, while pile yarn 14 is preferably formed as a monofilament and has a diameter of about 0.20 mm. With such materials, adhesive elements can be formed from the loops 16 of the pile thread 14 by means of the technique known from DE 102 40 986 B3. If the loops 16 are cut open by a thermal cutting or cutting operation to form the adhesive elements, the free ends of the loops can be made to shrink by further heating, wherein the ends can form closure bodies, preferably of a mushroom-like shape or also closure hooks. With diameters of the pile thread 14 of approximately 0.20 mm and with warp threads and weft threads which have 200 or 110 textex, packing densities of the adhesive elements formed of more than 150 / cm 2 can be realized. The weft density for the weft threads not shown in Fig. 3 may be in the range of 23 / cm.
Es versteht sich, dass anstelle von Polbindungen in Form einer W-Bindung mit einem Dreherpaar andere Bindungsarten vorgesehen sein könnten und/oder dass insbesondere für das Grundgewebe des Trägerteiles 10 beliebige, geeignete Kunststoffwerkstoffe in Frage kommen. It is understood that instead of pile bonds in the form of a W-bond with a leno pair, other types of weave could be provided and / or that, in particular for the base fabric of the support member 10, any suitable plastics materials come into question.
