Rundschlinge round sling
Die Erfindung betrifft eine Rundschlinge zur Verwendung an Tragmitteln mit einem die Rundschlinge partiell umschließenden ersten Schutzschlauch zur Bildung eines Stropps. The invention relates to a round sling for use on suspension means with a first protective tube partially surrounding the round sling to form a strop.
Rundschlingen und ein daraus gebildeter Stropp sind seit langem bekannt, so zum Beispiel aus der EP 32749 Al. Alle einzelnen Elemente der Rundschlinge, die den Stropp bilden, sind dabei bekanntermaßen irreversible miteinander verbunden, so vernäht. Ferner hat sich im praktischen Einsatz gezeigt, dass an Schlaufen der Rundschlinge in dem Bereich, an dem ein Tragmittel, so zum Beispiel ein Kranhaken, bei funktionsgemäßer Verwendung anliegt, ein erhöhter Verschleiß auftritt. Gleiches gilt für einen Lastaufnahmebereich, beispielsweise bei einem Transport eines Stahlcoils mithilfe einer Rundschlinge. Die Aufgabe der Erfindung besteht darin, eine Rundschlinge in Form eines Stropps weiter zu verbessern . Round slings and a strop formed from them have long been known, for example from EP 32749 Al. All individual elements of the round sling, which form the sling, are known to be irreversibly connected to each other, so sewn. Furthermore, it has been shown in practical use that increased wear occurs on loops of the round sling in the area where a suspension element, for example a crane hook, is in contact when used in a functional manner. The same applies to a load handling area, for example when transporting a steel coil using a round sling. The object of the invention is to further improve a round sling in the form of a sling.
Die Aufgabe wird erfüllt durch die Merkmale des Hauptanspruchs 1. Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Danach weist eine erfindungsgemäße Rundschlinge zur Verwendung an Tragmitteln folgende Merkmale auf. The object is achieved by the features of main claim 1. Further refinements of the invention result from the subclaims. According to this, a round sling according to the invention for use on suspension means has the following features.
Die Rundschlinge besitzt einen sie partiell umschließenden ersten Schutzschlauch zur Bildung eines Stropps, wobei Endbereiche der Rundschlinge nicht von dem ersten Schutzschlauch umschlossen sind und die Endbereiche daher Schlaufen bilden. The round sling has a first protective tube partially surrounding it to form a sling, end regions of the round sling not being enclosed by the first protective tube and the end regions therefore forming loops.
An dem ersten Schutzschlauch an seinen jeweiligen Enden ist in Richtung der Schlaufen mindestens je ein Umfassungsband als Schlaufenverstärkung angeordnet, dass an einer Außenfläche der jeweiligen Schlaufe der Rundschlinge anliegt und so um die Schlaufe gelegt ist. Das mindestens eine Umfassungsband ist vorzugsweise mit der Schlaufe nicht gesondert durch Vernähen, Verkleben oder Ähnlichem verbunden. On the first protective tube at its respective ends in the direction of the loops, at least one perimeter strap as loop reinforcement is arranged, which rests on an outer surface of the respective loop of the round sling and is thus placed around the loop. The at least one wrapping band is preferably not separately connected to the loop by sewing, gluing or the like.
Die Verbindung des mindestens einen Umfassungsbands mit dem ersten Schutzschlauch erfolgt aber beispielhaft durch Vernähen. Im Rahmen der Erfindung sind ebenfalls alle anderen geeigneten Verbindungsformen gelegen, so alle kraft- und/oder formschlüssigen oder stoffschlüssigen Verbindungsarten. The connection of the at least one surrounding tape to the first protective tube is, however, done by sewing, for example. All other suitable connection forms are also within the scope of the invention, so all non-positive and / or positive or material connection types.
Weiterhin ist an den jeweiligen Schlaufen jeweils ein öffenbarer zweiter Schutzschlauch angeordnet, der das Umfassungsband und damit gleichsam einen Bereich der Rundschlinge umschließt, an dem ein Tagmittel anordenbar ist und die Schlaufe und das Umfassungsband ganz oder zumindest teilweise verdeckt, das heißt in Längsrichtung axial verdeckt. Jedenfalls ist eine derartige Verdeckung notwendig, sodass eine funktionssichere Arretierung des jeweiligen Umfassungsbandes durch den zweiten Schutzschlauch gegeben ist. So ist durch den zweiten Schutzschlauch eine Fixierung des Umfassungsbandes als SchlaufenverStär ung sichergestellt . Furthermore, an openable second protective tube is arranged on the respective loops, which encloses the surrounding band and thus, as it were, an area of the round sling on which a tag means can be arranged and which completely or at least partially conceals the loop and the surrounding band, that is to say axially in the longitudinal direction. In any case, such a concealment is necessary, so that the respective protective tape is reliably locked by the second protective tube. The second protective hose ensures that the strap is fixed as a loop reinforcement.
Ein Verschlussbereich des jeweils zweiten Schut zschlauchs ist vorteilhafterweise außerhalb einer Kontaktfläche mit dem Tragmittel gelegen, um eine Beeinträchtigung des Verbindungsbereichs und damit eine Beeinträchtigung der Arretierung des jeweiligen zweiten Schut zschlauchs aufgrund einer mechanischen Beanspruchung durch das Tragmittel zu reduzieren. A closure area of the respective second protective hose is advantageously located outside a contact surface with the suspension element in order to reduce impairment of the connection area and thus impairment of the locking of the respective second protection hose due to mechanical stress by the suspension element.
Durch die erfindungsgemäße Anordnung und das Zusammenwirken der einzelnen vorbeschriebenen Bauteile wird die Tragfähigkeit der Rundschlinge weiter verbessert. Es wird die Kraftableitung innerhalb der Rundschlinge verbessert. Der mehrschichtige Aufbau verbessert ebenfalls die Haltbarkeit der Rundschlinge. Es ist ferner eine Wechselbarkeit einzelner Elemente der Rundschlinge in Form des Stropps gewährleistet. In weiterer Ausgestaltung der Erfindung kann vorgesehen werden, dass über dem ersten Schutzschlauch ein öffenbarer dritter Schutzschlauch angeordnet ist und den ersten Schutzschlauch im Wesentlichen umschließt. Dadurch kommt es zu einem verbesserten Schutz der Rundschlinge im Lastaufnahmebereich, wenn beispielhaft die Rundschlinge zum Transport von Coils, so Stahlcoils, eingesetzt wird . The load capacity of the round sling is further improved by the arrangement according to the invention and the interaction of the individual components described above. The power dissipation within the round sling is improved. The multilayer structure also improves the durability of the round sling. An interchangeability of individual elements of the round sling in the form of the sling is also ensured. In a further embodiment of the invention, it can be provided that an openable third protective tube is arranged above the first protective tube and essentially encloses the first protective tube. This results in improved protection of the round sling in the load handling area if, for example, the round sling is used to transport coils, according to steel coils.
Als ein Verbindungsmittel des öffenbaren zweiten und dritten Schutzschlauchs ist zum Beispiel ein Klettverschluss vorgesehen. Der erste Schutzschlauch kann mit der Rundschlinge wie bekannt vorzugsweise reversibel verbunden sein, indem er auf die Rundschlinge lose aufgeschoben ist oder aber, was aber nicht vorzugsweise der Fall ist, irreversibel mit der Rundschlinge verbunden sein, indem er auf die Rundschlinge im Rahmen der Bildung des Stropps lose aufgeschoben ist und sodann ein Bereich des ersten Schut zschlauchs zwischen beiden Strängen der Rundschlinge zumindest partiell verbunden, so vernäht ist. Der erste Schutzschlauch weist dann zwei Kammern auf. Nichtsdestotrotz ist er aber auf der Rundschlinge in aller Regel verschiebbar angeordnet und vorzugsweise sind wegen der Gewährung einer leichten Wechselbarkeit alle Verbindungen reversibel vorgesehen. A Velcro fastener, for example, is provided as a connecting means for the openable second and third protective tubes. As is known, the first protective tube can preferably be reversibly connected to the round sling by being loosely pushed onto the round sling or, which is not preferably the case, can be irreversibly connected to the round sling by being on the round sling as part of the formation of the Stropps is pushed on loosely and then an area of the first protective hose between the two strands of the round sling is at least partially connected, so it is sewn. The first protective tube then has two chambers. Nevertheless, as a rule it is arranged displaceably on the round sling, and preferably all connections are provided reversibly because of the ease of exchangeability.
Eine verbesserte Arretierung des ersten oder des ersten und des dritten Schutzschlauchs kann ferner mittels mindestens einem Verschluss erfolgen, wobei der mindestens eine Verschluss jeweils an den jeweiligen Enden des ersten Schutzschlauchs oder an den jeweiligen Enden des ersten und des dritten Schutzschlauchs angeordnet ist und vorzugsweise, aber nicht notwendigerweise, durch den Schlaufeninnenraum hindurchführt, wenn er verschlossen ist. Der mindestens eine Verschluss kann dabei mit dem ersten und/oder mit dem dritten Schutzschlauch fest verbunden sein oder aber ein separates Element darstellen, welches den ersten Schutzschlauch und/oder den dritten Schutzschlauch zwecks Arretierung durchdringen oder einklemmen kann. Vorteilhafterweise ist der mindestens eine Verschluss reversibel verschließbar, so beispielhaft mittels einer Klemmvorrichtung. In Betracht kommen Klemmschlösser, Schnallen oder ähnliche Vorrichtungen. In einer Variante ist der mindestens eine Verschluss ein Bandabschnitt. An improved locking of the first or of the first and of the third protective tube can furthermore take place by means of at least one closure, the at least one closure being arranged at the respective ends of the first protective tube or at the respective ends of the first and third protective tube and preferably, but does not necessarily lead through the interior of the loop when it is closed. The at least one closure can be firmly connected to the first and / or the third protective tube or can be a separate element which can penetrate or pinch the first protective tube and / or the third protective tube for the purpose of locking. The at least one closure is advantageously reversibly closable, for example by means of a clamping device. Clamp locks, buckles or similar devices come into consideration. In one variant, the at least one closure is a band section.
Die Erfindung wird nachfolgend anhand eines Äusführungsbeispiels unter Bezugnahme auf die Figur weiter erläutert. Dabei ergeben sich weitere Vorteile, Merkmale und Ausgestaltungen der Erfindung. The invention is further explained below using an exemplary embodiment with reference to the figure. This results in further advantages, features and refinements of the invention.
Es zeigt: It shows:
Fig. 1 eine schematische Darstellung einer erfindungsgemäßen Rundschlinge , 1 is a schematic representation of a round sling according to the invention,
Fig. 2 eine schematische Darstellung eines Teils einer Rundschlinge mit Endbereich. Fig. 2 is a schematic representation of part of a round sling with end area.
Eine erfindungsgemäße Rundschlinge 1 zur Verwendung an Tragmitteln besitzt einem sie partiell umschließenden ersten Schutzschlauch 2 zur Bildung eines Stropps, wobei Endbereiche der Rundschlinge 1 nicht von dem ersten Schutzschlauch 2 umschlossen sind und die Endbereiche daher Schlaufen 4, 4' bilden. A round sling 1 according to the invention for use on suspension means has a first protective tube 2 which partially surrounds it to form a sling, end regions of the round sling 1 not being enclosed by the first protective tube 2 and the end regions therefore forming loops 4, 4 '.
An dem ersten Schutzschlauch 2 an seinen jeweiligen Enden 3, 3' ist in Richtung der Schlaufen 4, 4' je ein Umfassungsband 5, 5' als Schlaufenverstärkung angeordnet. Das jeweilige Umfassungsband 5, 5' liegt an einer Außenfläche 6 der jeweiligen Schlaufe 4, 4' der Rundschlinge 1 lose an und ist so um die Schlaufe ohne weitere Befestigung gelegt. Das jeweilige Umfassungsband 5, 5' ist mit dem ersten Schutzschlauch 2 jeweils an den Enden 3, 3' gemäß der Fig. 1 und 2 zweimal beabstandet vernäht, sodass das jeweilige Umfassungsband 5, 5' ebenfalls eine Schlaufe bildet. Weiterhin ist an den jeweiligen Schlaufen 4, 4' jeweils ein öffenbarer zweiter Schutzschlauch 7, 7' angeordnet, der einen Bereich der Rundschlinge 1 umschließt, an dem ein Tragmittel anordenbar ist und gleichsam das jeweilige Umfassungsband 5, 5' fast vollständig verdeckt und so gleichsam arretiert. Ein Verschlussbereich des jeweils zweiten Schut zschlauchs 7, 7' ist im Ausführungsbeispiel außerhalb einer Kontaktflache mit dem Tragmittel gelegen, wenn dieses funktionsgemäß mit der Rundschlinge 1 verbunden ist. So ist der Verschlussbereich keiner direkten Beanspruchung durch das Tragmittel ausgesetzt. On the first protective tube 2 at its respective ends 3, 3 ', in each case in the direction of the loops 4, 4', a surrounding band 5, 5 'is arranged as a loop reinforcement. The respective surrounding band 5, 5 'lies loosely on an outer surface 6 of the respective loop 4, 4' of the round sling 1 and is thus placed around the loop without further attachment. The respective surrounding band 5, 5 'is sewn twice with the first protective tube 2 at the ends 3, 3' according to FIGS. 1 and 2, so that the respective surrounding band 5, 5 'also forms a loop. Furthermore, an openable second protective tube 7, 7 'is arranged on the respective loops 4, 4', which encloses a region of the round sling 1, on which a suspension element can be arranged and, as it were, almost completely conceals the respective encircling band 5, 5 ', and so to speak locked. In the exemplary embodiment, a closure area of the respective second protective hose 7, 7 'is located outside of a contact area with the suspension element when it is functionally connected to the round sling 1. This means that the locking area is not exposed to any direct stress from the suspension element.
Über dem ersten Schutzschlauch 2 ist ein öffenbarer dritter Schutzschlauch 8 angeordnet, der den ersten Schutzschlauch 2 im Wesentlichen umschließt, das heißt in seiner Längsrichtung verdeckt. Als ein Verbindungsmittel des öffenbaren zweiten und dritten Schut zschlauchs 7, 7' und 8 ist im Ausführungsbeispiel ein Klettverschluss vorgesehen. An openable third protective tube 8 is arranged above the first protective tube 2, which essentially surrounds the first protective tube 2, that is to say it conceals it in its longitudinal direction. In the exemplary embodiment, a Velcro fastener is provided as a connecting means for the openable second and third protective sleeves 7, 7 'and 8.
Eine verbesserte Arretierung des ersten und des dritten Schut zschlauchs 2, 8 erfolgt ferner mittels zweier Bandabschnitte, die einen Verschluss 9 bilden. Dabei ist der Verschluss 9 jeweils an den jeweiligen Enden 3, 3' des ersten Schut zschlauchs 2 und des dritten Schut zschlauchs 8 angeordnet. Der Verschluss 9 führt durch den Schlaufeninnenraum 10 hindurch, wenn er funktionsgemäß verschlossen ist. So ist ein Abziehen von der Rundschlinge 1 ausgeschlossen. Der Verschluss 9 wird im Ausführungsbeispiel durch jeweils zwei an den Enden 3, 3' angeordnete lösbare Gurte mit je einer Gurtklemme gebildet, wobei der Verschluss 9 den ersten Schutzschlauch 2 und den dritten Schutzschlauch 8 an dafür vorgesehenen Schlitzen durchdringt. Bezugszeichenliste An improved locking of the first and the third protective hose 2, 8 is also carried out by means of two band sections which form a closure 9. The closure 9 is arranged at the respective ends 3, 3 'of the first protective tube 2 and the third protective tube 8. The closure 9 leads through the loop interior 10 when it is closed in terms of its function. A pulling off from the round sling 1 is thus excluded. In the exemplary embodiment, the closure 9 is formed by two detachable straps each arranged at the ends 3, 3 ', each with a belt clamp, the closure 9 penetrating the first protective tube 2 and the third protective tube 8 at slots provided for this purpose.
