Abstract

The climbing-rope, comprising a core (1) with a sheath (8) surrounding the core, has an insulated electric conductor (2) which is wound helically onto the strands (6) of the core. This provides a signal connection, protected against damage, for the persons joined by the climbing rope, the said signal connection having a very low additional weight and being utilisable for other purposes as well. <IMAGE>

Description

Die Erfindung betrifft ein Kletterseil mit einer Kerneinlage und einem die Kerneinlage umgebenden Mantel.The invention relates to a climbing rope with a core insert and a sheath surrounding the core insert.

Kletterseile dienen als Sicherheitsseil beim Klettersport, bei Rettungseinsätzen, bei militärischen Übungen, bei Höhlenforschungen usw..Climbing ropes serve as safety ropes for climbing, rescue operations, military exercises, caving, etc.

Sowohl beim Klettersport als auch bei anderen Verwendungszwecken eines Kletterseiles spielt die Verständigung der durch das Seil verbundenen Personen eine wesentliche Rolle. Oft sind Rufverbindungen unsicher und unbefriedigend.Understanding the people connected by the rope plays an important role in both climbing and other uses of a climbing rope. Call connections are often insecure and unsatisfactory.

Der Einsatz von Funksprechgeräten ist in vielen Fällen nicht möglich, nämlich dann, wenn mit der Gefahr der Abschirmung gerechnet werden muß, bei ungünstigen atmosphärischen Situationen oder auch bei militärischen Einsätzen wegen der Gefahr des Mithörens.The use of two-way radios is not possible in many cases, namely when the risk of shielding must be expected, in unfavorable atmospheric situations or during military operations because of the risk of listening in.

Die Verwendung einer Kabelverbindung zwischen den einzelnen durch ein Kletterseil verbundenen Personen bringt wegen der zusätzlichen Gewichtsbelastung keine befriedigenden Ergebnisse. Auch ist ein elektrisches Kabel unhandlich.The use of a cable connection between the individual people connected by a climbing rope does not produce satisfactory results due to the additional weight load. An electrical cable is also unwieldy.

Ähnliche Probleme treten bei Filmaufnahmen auf oder auch dann, wenn Hilfsgeräte aus der Ferne bedient werden sollen.Similar problems arise with filming or when auxiliary devices are to be operated remotely.

Die Erfindung hat es sich zur Aufgabe gemacht, eine Einrichtung zu schaffen, die die erwähnten Probleme in bestmöglichster Weise beseitigt. Die Erfindung geht aus von einem Kletterseil der eingangs erwähnten Art und schlägt vor, daß die Litzen der Kerneinlage mit einem zum Beispiel zweiadrigen, isolierten, elektrischen Leiter schraubenförmig umwickelt sind.The invention has set itself the task of creating a device that eliminates the problems mentioned in the best possible way. The invention is based on a climbing rope of the type mentioned in the introduction and proposes that the strands of the core insert are helically wrapped with, for example, two-core, insulated, electrical conductors.

Das erfindungsgemäße Kletterseil ermöglicht nun in einfacher Weise sowohl einen Sprechverkehr wie auch eine Betätigung einer Filmkamera, von Signalen oder anderen Geräten.The climbing rope according to the invention now enables both speech communication and actuation of a film camera, signals or other devices in a simple manner.

Die zusätzliche Gewichtsbelastung ist extrem gering und kaum merklich. Es ist nämlich möglich, im Kletterseil einen verhältnismäßig dünnen elektrischen Leiter unterzubringen, der selbst ein geringes Gewicht hat.The additional weight load is extremely low and hardly noticeable. It is in fact possible to accommodate a relatively thin electrical conductor in the climbing rope, which itself is light in weight.

Durch die Anordnung im Seil ist der Leiter jedoch ausreichend geschützt, und zwar sowohl vor der Gefahr einer Beschädigung durch übermäßigen Zug, gegen übermäßige Knickung oder auch gegen äußere Beschädigung durch Scheuern od. dgl..Due to the arrangement in the rope, however, the conductor is adequately protected, both against the risk of damage due to excessive tension, against excessive kinking, or against external damage from chafing or the like.

Die Anordnung von Anschlüssen am Seilende bereitet keine Probleme. Es können hier die üblichen Mittel, z. B. Stecker oder Klemmverbindungen Verwendung finden.The arrangement of connections at the end of the rope presents no problems. The usual means, e.g. B. plugs or clamp connections are used.

Das erfindungsgemäße Kletterseil erfüllt somit eine Doppelfunktion. Dabei können beide Funktionen, nämlich als Sicherungsseil einerseits und als Verbindungsmittel zum Zwecke der Signal- oder Nachrichtenübermittlung gleichzeitig ausgenutzt . werden. Auch bleibt jede Funktion für sich allein nutzbar.The climbing rope according to the invention thus fulfills a double function. Both functions, namely as a safety rope on the one hand and as a connection means for the purpose of signal or message transmission can be used simultaneously. will. Each function also remains usable on its own.

Die schraubenförmige Umwicklung der Litzen der Kerneinlage bringt den Vorteil mit sich, daß bei extremen Beanspruchungen des Kletterseils, beispielsweise bei Stürzen von Lasten in das Seil der elektrische Leiter ausreichend nachgeben kann, so daß ein Bruch ausgeschlossen ist.The helical wrapping of the strands of the core insert has the advantage that the electrical conductor can yield sufficiently under extreme stresses on the climbing rope, for example when loads are dropped into the rope, so that breakage is excluded.

Bei einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß die Adern des elektrischen Leiters durch ihre Isolierung miteinander verbunden sind.In a preferred embodiment of the invention it is provided that the wires of the electrical conductor are connected to one another by their insulation.

An sich wäre es denkbar, die einzelnen Adern des elektrischen Leiters je für sich im Seil unterzubringen. Besser ist es jedoch, einen zweiadrigen Leiter, dessen Adern untereinander verbunden sind, im Seil anzuordnen.As such, it would be conceivable for the individual wires of the electrical conductor to be accommodated individually in the rope. However, it is better to arrange a two-wire conductor, the wires of which are interconnected, in the rope.

Der elektrische Leiter kann beispielsweise derart angeordnet werden, daß er die gesamte Kerneinlage des Seils umwickelt. Es ist jedoch günstiger, wenn der elektrische Leiter nur einen Teil der Litzen der Kerneinlage umgibt, wobei dann die anderen Litzen den elektrischen Leiter von außen abdecken.The electrical conductor can for example be arranged such that it wraps around the entire core insert of the rope. However, it is more favorable if the electrical conductor surrounds only a part of the strands of the core insert, the other strands then covering the electrical conductor from the outside.

Bei dieser Bauweise ist der elektrische Leiter von außen nicht mehr ertastbar. Auch bei geringfügigen Beschädigungen des Seils bleibt der Leiter noch geschützt.With this design, the electrical conductor can no longer be felt from the outside. The conductor remains protected even if the rope is slightly damaged.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Es zeigen:

  • Fig. 1 einen vergrößerten Schnitt durch ein Kletterseil gemäß der Erfindung und
  • Fig. 2 einen Schnitt durch die Darstellung der Fig. 1.
In the drawing, an embodiment of the invention is shown schematically. Show it:
  • Fig. 1 shows an enlarged section through a climbing rope according to the invention and
  • Fig. 2 shows a section through the representation of Fi g . 1.

Das Kletterseil ist als Kernmantelseil ausgebildet. Die Litzen 6 und 7 sind beispielsweise in sich gedreht und bestehen jeweils aus zwei oder drei einzelnen Strängen, die jedoch nicht näher dargestellt sind. Die Litzen 6 und 7 bilden zusammen die Kerneinlage 1. Die inneren Litzen 6 werden von dem elektrischen Leiter 2 umgeben, der schraubenförmig aufgewickelt ist, wie dies beispielsweise aus der Fig. 2 hervorgeht. Es können zwei oder mehrere innere Litzen 6 vorgesehen sein.The climbing rope is designed as a core sheath rope. The strands 6 and 7 are twisted, for example, and each consist of two or three individual strands, which are not shown in detail. The strands 6 and 7 together form the core insert 1. The inner strands 6 are surrounded by the electrical conductor 2, which is wound helically, as can be seen, for example, from FIG. 2. Two or more inner strands 6 can be provided.

Der elektrische Leiter besteht aus den beiden Adern 3 und 4, die durch die Isolation 5 untereinander verbunden sind.The electrical conductor consists of the two wires 3 and 4, which are interconnected by the insulation 5.

Die Litzen 6 und 7 zusammen mit dem elektrischen Leiter 2 werden von dem Mantel 8 umgeben, der, wie an sich bekannt, aus einem ein- oder mehrfarbigen Geflecht besteht.The strands 6 and 7 together with the electrical conductor 2 are surrounded by the sheath 8, which, as is known per se, consists of a single or multi-colored braid.
