Abstract

The invention relates to a chain strand (1), which has a plurality of chain links (2) having at least one layer (10) of a textile strap (4). At two locations (16), the chain link (2) is twisted, at a spacing in the circumferential direction (6), by one half rotation in each case, or an odd multiple of one half rotation, in the same direction of rotation (18) about the circumferential direction (6). This results in a symmetrical structure, an easily controllable load situation and uniform wear of the chain link, since the flat sides (22) of the two outer layers (10) between the locations (16) point toward the opening (8) and away from the opening (8), respectively.

Description

Kettenstrang mit textilen Kettengliedern aus verdrehtem Gurtmaterial Chain strand with textile chain links made of twisted belt material

Die Erfindung betrifft einen Kettenstrang mit ineinander gehängten Kettengliedern, die aus we nigstens einer Lage wenigstens eines textilen Gurtes aufgebaut sind. The invention relates to a chain strand with interlocking chain links which are constructed from at least one layer of at least one textile belt.

Aus dem Stand der Technik sind Kettenglieder einer textilen Kette bekannt, die aus achtlagigen Möbiusbändern aufgebaut ist. Im Betrieb weisen derartige textile Ketten Nachteile auf. Chain links of a textile chain made up of eight-layer Möbius strips are known from the prior art. Such textile chains have disadvantages in operation.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine verbesserte textile Kette zu schaffen. The present invention is therefore based on the object of creating an improved textile warp.

Diese Aufgabe wird für den eingangs genannten Kettenstrang dadurch gelöst, dass an zwei in Umfangsrichtung aufeinanderfolgenden Stellen die wenigstens eine Lage des Gurtes um eine halbe Umdrehung oder ein ungeradzahliges Vielfaches einer halben Drehung im gleichen Dreh sinn um die Umfangsrichtung verdreht ist. This object is achieved for the chain strand mentioned at the outset in that at two successive points in the circumferential direction the at least one layer of the belt is rotated by half a turn or an odd multiple of a half turn in the same direction of rotation around the circumferential direction.

Diese Maßnahme erlaubt es, das Kettenglied symmetrischer auszurichten. Ein weiterer Vorteil des erfindungsgemäßen Aufbaus besteht darin, dass die Garne auf den Flachseiten des Gurtes sowohl auf der Außenseite als auch der Innenseite des Kettengliedes zu liegen kommen und somit nach einem Umlauf des Gurtes um die Umfangsrichtung gleiche Länge aufweisen. This measure allows the chain link to be aligned more symmetrically. Another advantage of the structure according to the invention is that the yarns on the flat sides of the belt come to lie both on the outside and the inside of the chain link and thus have the same length after one revolution of the belt around the circumferential direction.

Die erfindungsgemäße Lösung kann durch die folgenden voneinander unabhängigen, jeweils für sich vorteilhaften und beliebig miteinander kombinierbaren Weiterbildungen nochmals verbessert werden. The solution according to the invention can be further improved by the following developments that are independent of one another, are each advantageous in themselves and can be combined with one another as desired.

So können die beiden verdrehten Stellen sich im Kettenglied einander gegenüberliegen, insbe- sondere bezüglich einer zentralen Öffnung des Kettengliedes. Hieraus resultiert ein symmetri scher Aufbau des Kettengliedes, der zu einer konstruktiv einfacher zu beherrschenden und zu verlässigeren symmetrischen Belastung des Gurtes führt. In this way, the two twisted points in the chain link can lie opposite one another, in particular with regard to a central opening in the chain link. This results in a symmetrical structure of the chain link, which leads to a structurally easier to control and to more reliable symmetrical loading of the belt.

Gemäß einer weiteren vorteilhaften Ausgestaltung kann in den sich nicht am Ende des Ketten stranges befindlichen Kettengliedern des Kettenstranges in Umfangsrichtung zwischen den ver- drehten Stellen jeweils ein Kettenglied eingehängt sein. Die nicht verdrehten Stellen des Ketten gliedes sind bei einer solchen Ausgestaltung diejenigen Stellen, an denen sich die beiden be nachbarten Kettenglieder des Kettenstranges abstützen bzw. angeordnet sind. According to a further advantageous embodiment, in each of the chain links of the chain strand that are not located at the end of the chain strand, a chain link can be suspended in the circumferential direction between the twisted points. The non-twisted points of the chain link in such a configuration are those points where the two adjacent chain links of the chain strand are supported or arranged.

Je nach zu erwartender Belastung und/oder Größe des Kettenstranges können mehr oder weni ger Lagen des Gurtes vorhanden sein. Insbesondere können mehrere, insbesondere sämtliche Lagen des Kettengliedes aus einem einzigen Gurt gewickelt sein. Hierzu wird der Gurt mehrfach um die Öffnung gewickelt. Der Gurt kann somit einen an zwei Stellen in sich verdrehten Wickel um eine gemeinsame Öffnung des jeweiligen Kettengliedes bilden. Die einzelnen Lagen des Gur tes liegen entlang der Umfangsrichtung mit ihren Flachseiten vollständig aufeinander. Anstelle des einen Gurtes können auch mehrere Gurte die wenigstens eine Lage bilden. Hierzu können nacheinander mehrere Gurte um die zentrale Öffnung gewickelt sein. Depending on the expected load and / or size of the chain strand, there may be more or fewer layers of the belt. In particular, several, in particular all Layers of the chain link can be wound from a single belt. To do this, the belt is wrapped around the opening several times. The belt can thus form a winding that is twisted in itself at two points around a common opening of the respective chain link. The individual layers of the belt lie completely on top of one another with their flat sides along the circumferential direction. Instead of the one belt, several belts can form the at least one layer. For this purpose, several straps can be wrapped around the central opening one after the other.

Die Enden eines Gurtes liegen sich bevorzugt bezüglich der Lagen bzw. in Dickenrichtung ge genüber und überlappen sich. Die Enden sind bevorzugt miteinander verbunden, beispielsweise vernäht und/oder vernietet. Eine Lage im Sinne dieser technischen Lehre erstreckt sich vollständig um die zentrale Öffnung. The ends of a belt preferably lie opposite one another with respect to the layers or in the direction of thickness and overlap. The ends are preferably connected to one another, for example sewn and / or riveted. A position in the sense of this technical teaching extends completely around the central opening.

In Umfangsrichtung können ferner die einzelnen Lagen durchgängig oder an voneinander beab- standeten Stellen miteinander verbunden, beispielsweise vernäht und/oder vernietet sein. Dies verbessert den strukturellen Zusammenhalt des Kettengliedes. In the circumferential direction, the individual layers can also be connected to one another continuously or at points spaced apart from one another, for example sewn and / or riveted. This improves the structural cohesion of the chain link.

Im Folgenden ist die Erfindung anhand eines Ausführungsbeispiels mit Bezug auf die Zeichnun- gen exemplarisch näher erläutert. Dabei werden in den Zeichnungen für Elemente, die einander hinsichtlich Form und/oder Funktion entsprechen, dieselben Bezugszeichen verwendet. In the following, the invention is explained in more detail using an exemplary embodiment with reference to the drawings. The same reference symbols are used in the drawings for elements that correspond to one another with regard to form and / or function.

Es zeigen: Show it:

Fig. 1 eine schematische Ansicht eines Kettenstranges; 1 shows a schematic view of a chain strand;

Fig. 2 eine schematische Ansicht eines Kettengliedes des Kettenstranges der Fig. 1. In Fig. 1 ist ein Kettenstrang 1 gezeigt, der eine Mehrzahl von ineinandergehängten Kettenglie dern 2 aufweist. Die Kettenglieder 2 müssen nicht identisch aufgebaut sein, sondern können, wie an dem gestrichelt dargestellten Kettenglied 2a exemplarisch dargestellt ist, einen unterschiedli chen Aufbau und/oder eine unterschiedliche Geometrie aufweisen und/oder aus unterschiedli chen Materialien gefertigt sein. Wenigstens ein Teil der Kettenglieder ist jedoch bevorzugt so aufgebaut, wie dies beispielhaft in Fig. 2 dargestellt ist. Fig. 2 is a schematic view of a chain link of the chain strand of FIG. 1. In Fig. 1, a chain strand 1 is shown, which has a plurality of countries 2 chain links interconnected. The chain links 2 do not have to be constructed identically, but can, as exemplified by the chain link 2a shown in dashed lines, have a different structure and / or a different geometry and / or be made of different materials. At least some of the chain links, however, are preferably constructed as shown by way of example in FIG.

Fig. 2 zeigt ein Kettenglied 2, das aus einem einzigen textilen Gurt 4 aufgebaut ist. In Umfangs richtung 6 ist der Gurt 4 mehrfach um eine zentrale Öffnung 8 des Kettengliedes 2 gewickelt. Die einzelnen Lagen 10 liegen bevorzugt vollflächig aufeinander. Somit weist das Kettenglied 2 meh rere Lagen 10 auf. Die Anzahl der Lagen 10 ist beliebig und kann zwischen 1 und 12 betragen. In Fig. 2 sind lediglich zu Anschauungszwecken drei Lagen dargestellt. FIG. 2 shows a chain link 2 which is constructed from a single textile belt 4. In the circumferential direction 6, the belt 4 is wound several times around a central opening 8 of the chain link 2. The individual layers 10 preferably lie on top of one another over their entire surface. The chain link 2 thus has several layers 10. The number of layers 10 is arbitrary and can be between 1 and 12. In Fig. 2 three layers are shown for illustrative purposes only.

Die Enden 12 des Gurtes 4 überlappen sich. Dies ermöglicht es, die Enden 12 durch die Lagen 10 hindurch über eine Naht 14 aneinander zu befestigen und dem Kettenglied 2, obwohl es aus einem biegeschlaffen Material gefertigt ist, eine strukturelle Integrität zu verleihen. Anstelle eines einzigen Gurtes können auch mehrere Gurte nacheinander um die zentrale Öffnung 6 gewickelt sein. Zusätzlich oder anstelle der Naht 14 kann auch eine andere Art der Verbindung der Enden 12 verwendet werden, beispielsweise ein Vernieten. Des Weiteren können an wenigstens einer weiteren Stelle wenigstens zwei, vorzugsweise alle Lagen 10 miteinander verbunden sein, um die strukturelle Integrität des Kettengliedes zu erhöhen. The ends 12 of the belt 4 overlap. This makes it possible to fasten the ends 12 to one another through the layers 10 via a seam 14 and to give the chain link 2 a structural integrity, although it is made of a pliable material. Instead of a single belt, several belts can be wrapped around the central opening 6 one after the other. In addition to or instead of the seam 14, another type of connection of the ends 12 can also be used, for example riveting. Furthermore, at least two, preferably all, layers 10 can be connected to one another at at least one other point in order to increase the structural integrity of the chain link.

An zwei Stellen 16, die in Umfangsrichtung aufeinander folgen, ist das Gurtmaterial jeweils über alle Lagen hinweg einmal um eine halbe Drehung oder ein ungeradzahlig Vielfaches einer halben Umdrehung, also um 180°, 540°, 900° etc. um die Umfangsrichtung verdreht. Die Drehung an den Stellen 16 erfolgt dabei jeweils im gleichen Drehsinn 18 um die Umfangsrichtung 6. At two points 16, which follow one another in the circumferential direction, the belt material is twisted once over all layers by half a turn or an odd multiple of a half turn, i.e. 180 °, 540 °, 900 ° etc. around the circumferential direction. The rotation at the points 16 takes place in the same direction of rotation 18 around the circumferential direction 6.

Die beiden Stellen 16 liegen sich bevorzugt bezüglich der Öffnung 8 gegenüber. Zwischen den beiden Stellen 16 ist das Kettenglied 2 nicht verdreht. Bei einem sich nicht an den Enden 20 des Kettenstranges 1 befindlichen Kettenglied 2b befinden sich bevorzugt die beiden in das Ketten glied 2b eingehängten, benachbarten Kettenglieder jeweils zwischen den Stellen 16, also im nicht verdrehten Bereich. The two points 16 are preferably opposite one another with respect to the opening 8. The chain link 2 is not twisted between the two points 16. In the case of a chain link 2b not located at the ends 20 of the chain strand 1, the two adjacent chain links suspended in the chain link 2b are preferably located between the points 16, that is, in the non-twisted area.

Wie zu erkennen ist, liegen die Flachseiten 22 des Gurtes 4 zwischen den Lagen 10 aufeinander. Zwischen den Stellen 16 weisen die Flachseiten radial nach innen, zur Öffnung 8, bzw. radial nach außen, weg von der Öffnung 8. Aufgrund der ungeradzahligen Drehung kommt zwischen den Stellen 16 einmal die eine Flachseite und ein anderes Mal die andere Flachseite 22 außen zu liegen. Die verdrehten Stellen 16 können insbesondere die Schenkel und die nicht verdrehten Stellen die Buge des Kettengliedes 2 bilden. As can be seen, the flat sides 22 of the belt 4 lie on top of one another between the layers 10. Between the points 16, the flat sides point radially inward, towards the opening 8, or radially outward, away from the opening 8. Due to the odd-numbered rotation, one flat side comes out between the points 16 and the other flat side 22 on the outside lie. The twisted points 16 can in particular form the legs and the non-twisted points the bend of the chain link 2.

Die abwechselnde Positionierung der Flachseite 22 auf der Innen- und Außenseite und der sym metrische Aufbau des Kettengliedes 2 führen zu einer gut beherrschbaren Belastungssituation im Gebrauch, zu einer einfachen Herstellung und zu einer gleichmäßigen Abnutzung der Ketten glieder 2. Der Kettenstrang 1 muss selbst nicht vollständig aus textilen Kettengliedern 2 gefertigt sein, son dern kann dazwischen auch beispielsweise metallene Kettenglieder 2a und/oder textile Ketten glieder 2a aufweisen, die anders geformt und/oder aufgebaut sind als die Kettenglieder 2. The alternating positioning of the flat side 22 on the inside and outside and the symmetrical structure of the chain link 2 lead to an easily controllable load situation in use, to simple manufacture and to even wear of the chain links 2. The chain strand 1 itself does not have to be made entirely of textile chain links 2, but can also have, for example, metal chain links 2a and / or textile chain links 2a in between, which are shaped and / or constructed differently than the chain links 2.

Der Gurt 4 bzw. die Gurte 4 können aus den verschiedensten Materialien aufgebaut sein. Insbe- sondere eignen sich für das Kettenglied hochfeste Fasern und Garne, um eine hohe Bruch- bzw. Reißfestigkeit zu erzielen. The belt 4 or the belts 4 can be constructed from a wide variety of materials. In particular, high-strength fibers and yarns are suitable for the chain link in order to achieve a high breaking strength or tear strength.
