Abstract

The detachable screw (3) for driving into ice, for instance: during abseiling. It can be unscrewed by means of a cable (4) to which it is fixed by means of a cord (5). A sleeve along part of which is a slot is pushed over the ice-screw (3). The non-slotted end of the sleeve is enclosed by a spool (1) fixed to it. The cord (5) is wound onto the spool (1). USE/ADVANTAGE - The screw for driving into ice, for abseiling down difficult parts of mountains, is simple and quick to manipulate.

Description

Bezeichnungdesignation Lösbare EisschraubeRemovable ice screw

Die Erfindung betrifft eine lösbare Eisschraube nach dem Oberbegriff des Anspruchs.The invention relates to a releasable ice screw according to the Preamble of the claim.

Stand der TechnikState of the art

Trifft eine Seilschaft beim Abstieg oder beim Rückzug im Gebirge an schwierige Stellen, kann sie diese durch Abseilen überwinden. Eine Abseilstelle erfordert immer einen sicheren Fixpunkt für das Seil. An Gletschern und Eisflanken gibt es dafür folgende Möglichkeiten.Meet a rope team while descending or retreating in the Mountains to difficult places, they can go through them Overcome abseiling. A descent always requires a safe fixed point for the rope. On glaciers and Ice flanks have the following options.

Methode 1Method 1 Lösbare SchraubeRemovable screw

Eisschraube, die mittels einer am Seil befestigten Schnur durch Seilzug herausschraubbar ist. Das Drehmoment wird durch Zug auf die um die Eisschraube gewickelte Schnur aufgebracht.Ice screw attached to the rope by means of a Cord can be unscrewed by a cable. The Torque is by pulling on the around the ice screw wound cord applied.

Kritikcriticism

Sehr schwierig anzubringen, muß jedoch 100%ig richtig angebracht sein, damit sie funktioniert; muß vor Gebrauch ausprobiert werden, daher problematisch und sehr zeitaufwendig (Zeitschrift "Deutscher Alpenverein", Heft 5, Sept./Okt. 84).Very difficult to install, but must be 100% correct be appropriate for it to work; must before Be tried out, therefore problematic and very time consuming (magazine "Deutscher Alpenverein", Issue 5, Sept./Oct. 84).

Methode 2Method 2 Eisschraube oder EishakenIce screw or ice hook Kritikcriticism

Einfach und schnell, aber Schraube bzw. Haken verbleiben nach dem Abziehen des Seils im Eis; Kosten, Umweltver­ schmutzung.Simple and quick, but the screw or hook remain after pulling the rope in ice; Costs, environmental ver dirt.

Methode 3Method 3 Abalakow-EislöcherAbalakov ice holes Kritikcriticism

Schwierige und zeitraubende Herstellung, Verlust der Schlinge, Kosten, Umweltverschmutzung. Difficult and time consuming manufacture, loss of Noose, cost, pollution.  

Methode 4Method 4 EisbirneIce pear Kritikcriticism

Sehr zeitaufwendige Herstellung.Very time consuming production.

Methode 5Method 5 T-VerankerungT-anchoring Kritikcriticism

Erfordert einen passenden Stein (woher nehmen auf Gletscher?), Verlust der Reepschnur, Kosten und Umwelt­ verschmutzung.Requires a matching stone (where to get from Glacier?), Loss of cord, costs and environment pollution.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, einen sicheren Fixpunkt zu schaffen, der wenig Zeit beansprucht, einfach zu handhaben ist und keinen Materialverlust zur Folge hat.The invention has for its object to a safe fixed point create that takes little time, is easy to use and does not result in loss of material.

Lösungsolution

Diese Aufgabe wird durch die Merkmale des Anspruchs gelöst.This object is solved by the features of the claim.

Erzielbare VorteileAchievable advantages 1. Sicherheit1. Security

Der Bergsteiger kann die sicherste Abseilmethode, nämlich Eisschraube plus aufgestülpter Spule anwenden ohne Materialverlust. Gegenüber der Methode 1 erhöht die Erfindung die Sicherheit beim Abseilen, weil der Durchmesser der Spule ein Abrutschen des Seils über den Eisschraubenkopf erschwert und weil der Angriffspunkt der Schnur immer möglichst nahe am Eis ist, was ein Verkanten der Eisschraube ver­ hindert (bei der Methode 1 bewegt sich der Angriffspunkt der Schnur vom Eis weg).The climber can use the safest abseiling method, namely ice screw plus use the put-on spool without loss of material. Opposite the Method 1 increases the safety of rappelling because of the Diameter of the coil slipping the rope over the Ice screw head difficult and because the point of attack of the cord always is as close to the ice as possible, which prevents the ice screw from tilting prevents (in method 1 the point of application of the cord moves from Ice away).

Außerdem kann die Eisschraube tiefer und damit sicherer ins Eis einge­ dreht werden als bei der Methode 1. In addition, the ice screw can be deeper and thus more safely into the ice be rotated than in method 1.  

2. Kosten und Umwelt2. Cost and environment

Die Erfindung spart Materialkosten und schont die Umwelt, da kein Material (weder Schrauben noch Schlingen) am Berg/im Eis zurückgelassen werden muß.The invention saves material costs and protects the environment, since none Material (neither screws nor slings) left on the mountain / in the ice must become.

3. Zeitersparnis3. Time saving

Die Erfindung bringt erhebliche Zeitersparnis gegenüber allen Methoden (außer 2), zum Teil bis zu 45 Minuten. Dadurch erhöht sich wiederum die Sicherheit, da der Rückzug in kürzerer Zeit durchgeführt werden kann (z. B. drohender Wetterumschwung, Nacht).The invention saves considerable time compared to all methods (except 2), sometimes up to 45 minutes. This in turn increases the Security because the withdrawal can be done in less time (e.g. impending weather change, night).

4. Anwendbarkeit4. Applicability

Die Erfindung ermöglicht beliebig häufiges Abseilen, da kein Materialverlust entsteht.The invention enables abseiling as often as desired, since none Material loss occurs.

Die Ausschraubspule zum Lösen der Eisschraube ist im folgenden an Hand eines Ausführungsbeispieles näher erläutert, es zeigtThe unscrewing coil for loosening the ice screw is shown below of an embodiment explained in more detail, it shows

Beschreibung des AusführungsbeispielsDescription of the embodiment

Die Ausschraubspule 1 wird über die Eisschraube 3 geschoben. Die Abseilstelle wird mit einer Eisschraube 3 plus Ausschraubspule 1, dem Seil 4, und einer Schnur 5 so eingerichtet, wie es in dem Ausführungsbeispiel in Fig. 2 gezeigt wird. Nach dem Abseilen wird an dem Seilende, das mit der Schnur 5 verbunden ist, gezogen. Die aufgewickelte Schnur wird nun durch die Zugkraft abgewickelt, dadurch dreht sich die Ausschraubspule 1 und mit ihr die Eisschraube 3. So wird die Eisschraube herausgedreht, sie verliert ihren Halt und fällt herunter. Durch die Schnur 5 ist sowohl die Ausschraubspule 1 als auch die Eisschraube 3 mit dem Seil 4 verbunden und vor Verlust gesichert. Jetzt kann die Seilschaft die Geräte vom Seil 4 nehmen und bei Bedarf damit eine neue Abseilstelle einrichten.The unscrewing coil 1 is pushed over the ice screw 3 . The abseiling point is set up with an ice screw 3 plus unscrewing coil 1 , the rope 4 , and a cord 5 as shown in the exemplary embodiment in FIG. 2. After abseiling, the end of the rope connected to the cord 5 is pulled. The wound cord is now unwound by the tensile force, which causes the unscrewing spool 1 and with it the ice screw 3 . So the ice screw is unscrewed, it loses its hold and falls down. By the cord 5 , both the unscrewing coil 1 and the ice screw 3 are connected to the rope 4 and secured against loss. Now the rope team can remove the devices from rope 4 and set up a new abseiling point if necessary.
