Abstract

A sling band for lifting loads is disclosed. The sling band has a first band, a second band and overlapping areas, whereby the ends of the bands lead into the overlapping areas. The first band includes first warp threads and the second band includes second warp threads, whereby the warp threads, together with weft threads, form a first and a second weave. In the overlapping areas, the warp threads are joined to one another where they form a web construction with the weft threads. The web construction includes at least one additional third weave that differs from the first and second weaves. A portion of the warp threads has a lower melting point than that of the remaining warp threads thus enabling the interwoven overlapping areas to be provided with increased strength using a weld.

Description

Hebeband lifting sling
Die Erfindung betrifft ein Hebeband gemäss Patentanspruch 1 sowie Verwendungen desselben gemäss Patentanspruch 6 bis 8.The invention relates to a lifting sling according to patent claim 1 and uses thereof according to patent claims 6 to 8.
Hebebänder gelangen im Transportwesen und insbesondere in der Baubranche zur Anwendung.Lifting straps are used in transportation and especially in the construction industry.
Gewobene ein- oder zweilagige Endloshebebänder werden in grossen Mengen für das Heben von Lasten gemäss den europäischen Normen EN 1492-1 (Sicherheit: Anforderungen an flachgewebte Hebebänder aus Chemiefasern) und EN 1492-2 (Sicherheit: Anforderungen an Rundschlingen aus Chemiefasern) verwendet. Fig. 1 zeigt die Ansicht eines bekannten, einlagigen Endloshebebandes gemäss EN 1492-1. Diese textilen Bänder werden überlappend zusammengenäht, damit sie für den Anwender die geeignete Lieferform erhalten.Woven single or double-layer endless lifting straps are used in large quantities for lifting loads in accordance with the European standards EN 1492-1 (safety: requirements for flat woven lifting straps made of synthetic fibers) and EN 1492-2 (safety: requirements for round slings made of synthetic fibers). 1 shows the view of a known, single-layer endless lifting belt in accordance with EN 1492-1. These textile tapes are sewn together so that they receive the appropriate delivery form for the user.
Nach der US 5,498,047 ist eine textile, abriebfeste Hebeschlinge bekannt, bei der übereinanderliegende Gewebezonen miteinander vernäht werden.According to US Pat. No. 5,498,047, a textile, abrasion-resistant lifting sling is known in which tissue zones lying one above the other are sewn together.
Nachteilig sind dabei die sehr arbeitsintensiven Nähvorgänge, wobei dadurch die ursprüngliche Festigkeit des Bandes herabgesetzt wird. Aus diesem Grund muss die Festigkeit des verwendeten Bandes bedeutend höher gewählt werden, als dies für die vorgesehene Anwendung vorgeschrieben wäre. Versuche haben ergeben, dass ein Ersatz des Nähvorganges durch Schweissen oder Verkleben aus Sicherheitsgründen weitgehend fehlgeschlagen sind. Einzig bei einigen wenigen Anwendungen, bei denen die Festigkeit, bzw. die Bruchlast eine untergeordnete Rolle spielte, hat sich das Verschweissen durchgesetzt. Schweissnähte an textilen Bändern haben den Nachteil, dass unmittelbar neben der Schweissnaht ein Schwächung des Materials auftritt, die mehr oder weniger stark sein kann. Weiter ist bekannt, dass mit sogenannten Nadelwebstühlen für textile Bänder mehrere Gewebelagen direkt übereinander gewoben werden können. Die Verbindung zwischen den Gewebelagen hat sich aber bis jetzt als ungeeignet für die Verwendung von Hebebändern erwiesen. Überraschenderweise hat sich jetzt gezeigt, dass eine genügende Überlappung von zwei übereinander gewobenen Gewebeschichten und eine spezielle erfindungsgemässe Webkonstruktion zu einer für Endloshebebänder geeigneten und sicheren Bruchlast führen kann.Disadvantages are the very labor-intensive sewing processes, whereby the original strength of the tape is reduced. For this reason, the strength of the tape used must be chosen significantly higher than would be required for the intended application. Tests have shown that replacement of the sewing process by welding or gluing has largely failed for safety reasons. Only in a few applications in which the strength or the breaking load played a subordinate role has welding become established. Weld seams on textile tapes have the disadvantage that a weakening of the material occurs directly next to the weld seam, which can be more or less strong. It is also known that so-called needle looms for textile tapes can be used to weave several fabric layers directly one above the other. The connection between the fabric layers has so far proven unsuitable for the use of lifting straps. Surprisingly, it has now been shown that a sufficient overlap of two fabric layers woven over one another and a special woven construction according to the invention can result in a safe breaking load suitable for endless lifting tapes.
Es ist die Aufgabe der vorliegenden Erfindung, ein Hebeband vorzuschlagen, bei dem auf einen Nähvorgang verzichtet werden kann, wodurch die erwähnten Nachteile behoben werden.It is the object of the present invention to propose a lifting strap in which a sewing process can be dispensed with, as a result of which the disadvantages mentioned are eliminated.
Eine weitere Aufgabe besteht in der Beschreibung verschiedener Verwendungen von derartigen Hebebändern.Another object is to describe various uses of such lifting straps.
Erfindungsgemäss wird diese Aufgabe mit einem Hebeband gemäss dem Wortlaut nach Patentanspruch 1 gelöst und mit Verwendungen gemäss dem Wortlaut nach Patentanspruch 6 bis 8.According to the invention, this object is achieved with a lifting strap according to the wording according to claim 1 and with uses according to the wording according to claim 6 to 8.
Die Erfindung wird im Folgenden anhand der Zeichnung näher erläutert. Es zeigen:The invention is explained in more detail below with reference to the drawing. Show it:

Fig. 1 zeigt die perspektivische Ansicht eines bekannten, einlagigen Endloshebebandes. Die beiden Enden 1 und 1' eines Bandes 10 werden in einem Überlappungsbereich 2 übereinandergelegt und vernäht, was auf verschiedenste Arten erfolgen kann.Fig. 1 shows the perspective view of a known, single-layer endless lifting belt. The two ends 1 and 1 'of a tape 10 are placed one above the other in an overlap area 2 and sewn, in a variety of ways can be done.
Fig.2 zeigt die perspektivische Ansicht eines erfindungsgemässen Endloshebebandes nach dem Weben und Abschneiden. Ein Band 20 besteht zwei Lagen 3 und 3', die als zweilagiges Band gewoben wurden, wobei die .Webstellen 4 und 4' während dem Weben übereinander lagen. Das Band 20 weist eine Webstelle 5 auf, ab der die beiden Kettbahnen der Lagen 3 und 3' vereint werden, wodurch sich bis zu einer weiteren Webstelle 6 ein Überlappungsbereich 7 der Kettbahnen ergibt, in dem die beiden Kettbahnen miteinander mittels einer speziellen Webkonstruktion verwoben vorliegen. Das erste Band 3 weist erste Kettfäden 8 und das zweite Band 3' zweite Kettfäden 8' auf, wobei die Kettfäden 8, 8' mit Schussfäden eine erste und eine zweite Bindung bilden. In den Überlappungsbereichen 7, 7' werden die Kettfäden 8, 8' zusammengeführt, wo sie mit den Schussfäden eine Webkonstruktion bilden, die mindestens eine weitere dritte Bindung aufweist, die sich von der ersten und zweiten Bindung unterscheidet. Auf diese Weise entsteht im Überlappungsbereich 7 ein zweilagiges Band, das sich durch besondere Festigkeit auszeichnet. Die Webstelle 6 ist gleichzeitig auch eine Schnittstelle, an der das Band geschnitten wird. In analogerweise weist das Band 20 eine Webstelle 5', eine Webstelle 6' und ein Überlappungsbereich T auf mit dem Unterschied, dass der Webvorgang beginnend bei der Webstelle 6' vorerst ein zweilagiges Band im Überlappungsbereich T erstellt, um dann an der Webstelle bei aufgeteilten Kettbahnen zweilagig weite rzuweben, wobei die Lagen 3 und 3' entstehen. Das erfindungsgemässe Endloshebeband entsteht so durch blosses Abschneiden, bzw. Austrennen aus einem endlosen Webgut, das alternierend aus einem zweilagigen Band 3, 3' und einlagigen Überlappungsbereichen 7, T besteht. Nachdem die verwendeten Webkonstruktionen in den Überlappungsbereichen 7, 7' eine vielfach hinreichende Festigkeit aufweisen, lassen sich so in vorteilhafter Weise unter Umgehung eines jeglichen Nähvorganges Endloshebebänder herstellen. Wird für einen Teil der Kettfäden 8, 8' eine Faser mit einem tieferen Schmelzpunkt gewählt als dies für die übrigen Kettfäden der Fall ist, kann in den verwobenden Überlappungsbereichen 7, T anschliessend mit einer Verschweissung eine erhöhte Festigkeit erzielt werden.2 shows the perspective view of an endless lifting belt according to the invention after weaving and cutting. A band 20 consists of two layers 3 and 3 ', which were woven as a two-layer band, the weaving points 4 and 4' being superimposed during the weaving. The belt 20 has a weaving point 5, from which the two warp sheets of the layers 3 and 3 'are combined, which results in an overlap area 7 of the warp sheets up to a further weaving point 6, in which the two warp sheets are interwoven with one another by means of a special weaving construction , The first band 3 has first warp threads 8 and the second band 3 'has second warp threads 8', the warp threads 8, 8 'forming a first and a second weave with weft threads. The warp threads 8, 8 'are brought together in the overlap regions 7, 7', where they form a weave construction with the weft threads which has at least one further third weave, which differs from the first and second weave. In this way, a two-layer tape is formed in the overlap area 7, which is characterized by particular strength. The weaving point 6 is also an interface at which the tape is cut. In an analogous manner, the band 20 has a weaving point 5 ', a weaving point 6' and an overlap area T with the difference that the weaving process, starting with the weaving point 6 ', initially creates a two-layer band in the overlapping area T, and then at the weaving point with divided warp webs to weave in two layers, creating layers 3 and 3 '. The endless lifting belt according to the invention is thus produced by simply cutting off or separating it from an endless woven material which alternately consists of a two-layer band 3, 3 'and single-layer overlap regions 7, T. Since the weave constructions used in the overlap regions 7, 7 'have sufficient strength in many cases, endless lifting straps can thus advantageously be produced by bypassing any sewing process. If a fiber with a lower melting point is selected for part of the warp threads 8, 8 'than is the case for the other warp threads, an increased strength can then be achieved in the interweaving overlap regions 7, T by welding.

Erkennbar sind die zweilagigen Band 3, die einlagigen Überlappungsbereiche 7, 7' mit den Webstellen 5, 5' und die Webstellen 6, 6', die gleichzeitig auch die Schnittstellen des Endloshebebandes 20 darstellen.3 shows a plan view of an endless lifting belt according to the invention. recognizable are the two-layer tape 3, the single-layer overlap areas 7, 7 'with the weaving points 5, 5' and the weaving points 6, 6 ', which at the same time also represent the interfaces of the endless lifting belt 20.
Fig. 4 zeigt ein erstes Ausführungsbeispiel eines Endloshebebandes mit einer Bruchkraft von 800 kg.Fig. 4 shows a first embodiment of an endless lifting belt with a breaking force of 800 kg.
Ein 25 mm breites Band aus hochfesten Polyesterfasern wurde zweitägig gewoben, dass eine Lichtweite von 20 cm entstand. Die Faserfestigkeit war grösser als 80 cN/Tex. In den Überlappungsbereichen wurden die beiden Lagen verwoben über eine Länge von 2,5 cm.A 25 mm wide band made of high-strength polyester fibers was woven for two days to create a light width of 20 cm. The fiber strength was greater than 80 cN / Tex. In the overlap areas, the two layers were woven over a length of 2.5 cm.
Fig. 5 zeigt ein zweites Ausführungsbeispiel eines Hebebandes als Fangriemen für eine Skibindung in Draufsicht.Fig. 5 shows a second embodiment of a lifting strap as a lanyard for a ski binding in plan view.
Ein 12 mm breites Band aus Polyamidfasern wurde zweilagig gewoben, dass eine Lichtweite von 22 cm entstand. In den Überlappungsbereichen wurden die beiden Lagen über eine Länge von 1,5 cm verwoben. Nach dem Abtrennen des Bandes wurde dieses gewendet und in den Überlappungsbereichen zusätzlich vernäht. Es resultierte eine Tragkraft von mehr als 200 daN.A 12 mm wide band made of polyamide fibers was woven in two layers to create a light width of 22 cm. In the overlap areas, the two layers were woven over a length of 1.5 cm. After the tape had been cut off, it was turned and additionally sewn in the overlap areas. The result was a load capacity of more than 200 daN.
Fig.6 zeigt ein drittes Ausführungsbeispiel eines Hebebandes mit umspritztem Spannelement als Zurrgurt. Ein Hebeband 10, das im Wesentlichen der Fig. 4 entspricht, ist hier für eine Tragkraft von 300 kg ausgelegt. Es wird nun in ein Spritzwerkzeug eingelegt, mit dem ein Spannelement 30 mit Spannbügel 31 aus Kunststoff gespritzt werden kann. Die verwobenen Überlappungsbereiche sind 3,5 cm lang.Fig. 6 shows a third embodiment of a lifting strap with molded clamping element as a lashing strap.
