Abstract

The brake consists of an eccentrically-mounted wheel (2) and a fixed stop (3); the rope passes between the wheel and the stop, then round the wheel; a pull on the rope turns the wheel and jams the rope between it and the stop. In another version, an elliptical wheel is centrally mounted; then two stops can be used. The wheel (or, stop) has a V-groove in its edge to retain the rope. The device is fastened to the mountaineer's chest and as well as the eccentric wheel (2) and stop (3), it has a fixed disc (4) - to exert frictional braking as well as to turn the rope in the required direction - and handle (5) by which the braking effect of the eccentric wheel (2) can be controlled.

Description

Vorrichtung zum Bremsen von Seilen, insbesondere von Testilseilen.Device for braking ropes, in particular test ropes.

Die Erfindung betrifft eine Vorrichtung zum Bremsen von Seilen, insbesondere von Textilseilen, beispielsweise zum Abseilen son Isten und/oder Personen bei der alpinen Rettung, Bergsteigern, ER6hlenforschern.The invention relates to a device for braking ropes, in particular of textile ropes, for example for abseiling son Isten and / or people at the alpine rescue, mountaineers, explorers.

Es ist bekannt, zum Bremsen von Seilen Bremskarabiner, Bremsbacken, Abseilachter sowie Bbemsrollen zu terwenden, wobei bei allen Vorrichtungen, außer denen die mit Bremsbacken arbeiten, nur die Reibung der Umschlingung genützt wird.It is known to use brake carabiners, brake shoes, Eight descenders and brake rollers to be used, with all devices except those who work with brake shoes, only the friction of the wrap is used.

Die Funktion aller bekannten Vorrichtungen ist stark von der Besohaffenheit der Seile wie; Seildurchmesser, Flechtart, Flexibilität, Material Seilgewicht, Feuchtigkeit, Verschmutzung und Vereisung abhängig.The function of all known devices is largely dependent on the condition of ropes like; Rope diameter, braiding type, flexibility, material rope weight, moisture, Soiling and icing dependent.

Die bekannten Vorrichtungen sehen keine Sicherungsmöglichkeiten vor, die das unkontrollierte Durchlaufen eines Seiles bei Ausfall der Bedienung verhindern. Bei den bekannten Vorrichtungen stellen sich anhand der alftretenden Lasten, sowie der Seilbeschaffenheit bestimmte Bremskräfte ein, die nicht stufenlos variiert werden können.The known devices do not provide any security options, which prevent the uncontrolled passage of a rope in the event of failure of the operator. In the case of the known devices, the alftetrading loads, as well as the properties of the rope apply certain braking forces that are not continuously varied can.

Angesicht dieser Mängel bekannter Vorrichtungen liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zu schaffen, welche das Bremsen durchlaufender Seile ermöglicht und dabei einesichere Funktion bei verschiedener Seilbeschaffenheit sowie bei Bedienungsausfall gewährleistet.It is in light of these shortcomings in known devices that the invention resides the object of the invention is to create a device which makes braking more continuous Enables ropes to function safely with different rope properties as well as in the event of operator failure.

Gemäß der Erfindung ist diese Aufgabe dadurch gelöst, daß das Seil um ein Umlenkelement derart gerührt ist, daß das Seil bei Belastung von dem Umlenkelement gegen Widerlager gedrückt wird.According to the invention, this object is achieved in that the rope is stirred around a deflecting element in such a way that the rope is under load from the deflecting element is pressed against abutment.

Die er'findungsgemäße Vorrichtung verhindert somit ein unkontrolliertes Dnrchlaufen des Seiles bei Bedienungsausfall und ist durch die selbsthemmende Wirkung eine dynamische Sturz-Sicherung für Bergeteiger und andere Personen, die in Ausübung ihres Sportes oder Berufes in Sturzgefahr sind.The device according to the invention thus prevents an uncontrolled The rope runs through in the event of failure of operation and is due to the self-locking effect a dynamic fall protection for mountain climbers and other people who exercise in their sport or job are in danger of falling.

In den Unteransprüchen sind weitere Merkmale, Einzelheiten und Vorteile der Erfindung gekennzeichnet.The subclaims contain further features, details and advantages of the invention.

Anhand der folgenden Zeichnungen und der Beschreibung ist die Erfindung an zwei Ausführungsbeispielen einer Seilbremse dargestellt. In der Beschreibung sind weitere Merkmale, Einzelheiten und Vorteile der Erfindung aufgeführt.The invention is complete with reference to the following drawings and description shown on two embodiments of a rope brake. In the description further features, details and advantages of the invention are listed.

Fig. 1 zeigt die Aufsicht auf eine erfindungsgemaß ausgebildete Seilumlenkung. Fig. 1 shows the plan view of a rope deflection designed according to the invention.

Fig. 2 zeigt eine Aufsicht auf eine erfindungegemaß ausgebildete Seilbremse. Fig. 2 shows a plan view of a trained according to the invention Rope brake.

Fig. 3 zeigt eine Aufsicht auf eine Ausfu1irungsvariante der erfindungegemäß ausgebildeten Seilbremse. 3 shows a plan view of a variant of the embodiment according to the invention trained rope brake.

Fig. 4 zeigt eine Ausführungsvariante der Seilumlenkung Fig. 5 zeigt eine Ausführungsvariante der Widerlager Wie Fig. 1 zeigt, ist das Seil 1 um ein exzentrisch gelagertes Umlenkelement 2 geführt, welches durch Zug des Seiles in Pfeilrichtung gegen das Widerlager 3 drückt und das Seil 1 bremst. Fig. 4 shows a variant of the cable deflection Fig. 5 shows an embodiment of the abutment As Fig. 1 shows, the rope 1 is around a eccentrically mounted deflection element 2 out, which by pulling the rope in Direction of the arrow presses against the abutment 3 and the rope 1 brakes.

In Fig. 2 ist eine erfindungsgemäß ausgebildete Seilbremse gezeigt; mit einer exzentrisch gelagerten Umlenkrolle 2 und einer weiteren feststehenden Seilumlenkung 4, welche die Bremswirkung durch den zusätzlichen Umschlingungswinke 1 erhöht.In Fig. 2, a rope brake designed according to the invention is shown; with an eccentrically mounted pulley 2 and another stationary one Cable deflection 4, which the braking effect through the additional wrap angle 1 increased.

Durch die selbsthemmende Bremswirkung der Seilbremse ist diese, für Bergsteiger, Höhlenforscher, Feuerwehrleute und allen Personen, die durch Steinschlag oder anderen Einflüssen bedienungsunfähig werden können, eine sichere Abseilvorrichtung.Due to the self-locking braking effect of the rope brake, this is for Mountaineers, cave explorers, firefighters and anyone affected by falling rocks or other influences can render a safe abseiling device inoperable.

Anhand des Hebels 5 wird der Abstand zwischen der Seilumlenkung 2 und des Widerlager 3 über den Exzenter verändert, was ein gleichmäßiges Bremsen verschiedener Seile mit unterschiedlicher Beschaffenheit gewahrleistet. Die Grundplatte 7 wird mit den Befestigungsbohrungen 6 fixiert, beispielsweise am Körper eines Abseilenden mit einem Brust- Sitzgeschirr.Using the lever 5, the distance between the rope deflection 2 and the abutment 3 changed via the eccentric, resulting in even braking different ropes with different properties. The base plate 7 is fixed with the fastening bores 6, for example on the body of a descender with a chest seat harness.

Fig. 3 zeigt eine Ausführungrvariante zu Fig. 2 mit einem länglich ausgebildeten Umlenkelement 8 und zwei Widerlagern 3, die selbsthemmende Bremswirkung wird dadurch erhöht. Ein weiterer Vorteil der unter Figr 1, 2 und 3 beschriebenen Vorrichtung besteht darin, daß durch die selbsthemmende Wirkung dieses Bremssystems zum dynamischen Sichern.son Bergsteigern und anderen Personen dient, die bei der Ausübung ihres Sportes oder Berufes in Sturzgefahr sind.Fig. 3 shows a variant of Fig. 2 with an elongated formed deflection element 8 and two abutments 3, the self-locking braking effect is thereby increased. Another advantage of those described under FIGS. 1, 2 and 3 The device is that by the self-locking effect of this braking system for dynamic backup .son is used by mountaineers and other people involved in the Practicing their sport or job are in danger of falling.

Fig. 4 u. 5 zeigen eine Ausfuhrungsvariante der zweiten Seilumlenkung und der Widerlager.4 and 5 show a variant embodiment of the second rope deflection and the abutment.

Durch die keilförmige Ausführung der Seilumlenkung oder der Widerlager wird bei gleichem Anpressdruck des Seiles gegen das Widerlager die Bremswirkung erhöht.Due to the wedge-shaped design of the rope deflection or the abutment the braking effect is achieved with the same contact pressure of the rope against the abutment elevated.
