DE102012011572A1 - Safety device for climbing rope, has clasping opening that is designed as bracket, where clamping function is released by manual operation of bracket such that climbing rope is further transported and is held in transport position - Google Patents

Abstract

The safety device has a metal body with a support surface, and a clasping opening for a carabiner, with which the safety device is fixed to a climbing harness. The clasping opening is designed as a bracket. The support surface is pulled on the suspended carabiner, and a brake rope between the carabiner body and the safety device is disconnected through the shape of the safety device during strain on the load rope. The clamping function is released by manual operation of the bracket such that the climbing rope is further transported and is held in a transport position.

Description

The invention relates to a safety device for a climbing rope according to the preamble of claim 1.

From the DE10 2011 101 930 a safety device for a climbing rope is known, which consists of a multi-part metal body.

Through a slot in the metal body, a climbing rope can be inserted. With a carabiner, the safety device can be fixed to a harness. For this purpose, the carabiner is hooked into a provided on the metal body slot guide.

About a provided on the securing device lever a cable blockage can be canceled and the braking force of the device can be reduced. This safety device is very expensive, relatively heavy and expensive from the EP 1971407 is a simpler safety device for a climbing rope is known in which an eyelet is provided as loss protection for a carabiner.

The object of the invention is to provide a safety device for a climbing rope, which is very light, which is simple and which is easy to use.

This object is achieved by the features specified in claim 1.

Advantageous embodiments of the invention are specified in the subclaims.

The essential idea of the invention is that a hook provided on the securing device for a carabiner is designed as a bracket and by pressing the bracket in use, the clamping function for the climbing rope is releasable so as to weiterzutransportieren the climbing rope.

The bracket has a thumb area where the user must insert his thumb to manually operate the safety device.

In a simple embodiment of the invention, the bracket can be designed as a wire hanger.

It is also conceivable to form the bracket as an aluminum part or as a precision casting.

The prior art shows only securing devices that are suitable for wire thicknesses of 7.5 mm or more.

The safety device according to the invention is also suitable for thin climbing ropes of 6.9 mm.

In one embodiment of the invention, the main body of the securing device or the entire securing device are manufactured in one piece.

For ease of handling, portions of the stirrup are being made with an angled portion of the stirrup formed as a thumb portion.

The invention is explained in more detail with reference to an embodiment shown in the drawing.

1 shows a perspective view of a safety device according to the invention for a climbing rope. The safety device consists essentially of a metallic base body with a bracket. The metal body has a support surface for the climbing rope. To use the safety device, a loop of the climbing rope must be passed through a slot in the safety device. In the loop and the hanger as Einhaköffnung a carabiner is hooked, the z. B. is fixed to a harness. The bracket serves as a loss protection on the one hand.

In one position of the device, the climbing rope is disconnected. When pulling on the load rope, the support surface is pulled onto the hinged carabiner and disconnected by the shape of the safety device, the brake cable. From this position, the climber can bring the safety device in a release position with reduced braking force. To do this, he has to insert his thumb into the thumb area of the stirrup and move the stirrup upwards ( 7 ).

• – neue Drahtgeometrie/neue Bügelgeometrie
• – starke Reduzierung des Gewichts
• – Eignung auch für extrem dünne Seile (kleiner als 7 mm Durchmesser)
• – Vereinigung von 2 Systemausprägungen im Sicherungsgerät-Bereich: ”normaler” Tuber z. B. ( EP 1971407 ) mit rundem Drahtbügel und einem Sicherungsgerät analog DE 10 2011 101 930 ohne Bügel
• – die erfindungsgemäße Sicherungsvorrichtung hat einen sehr kurzen Hebel
• – der Bügel hat eine neue Funktion: er dient nicht mehr nur als Halte- bzw. Positionierungsbügel, sondern auch als Betätigungsbügel, der zusätzlich zur Verriegelung und Entriegelung der Bremsfunktion dient
• – die Entriegelung muss bei der erfindungsgemäßen Sicherungsvorrichtung aktiv erfolgen

The essential aspects of the invention are:

• - new wire geometry / new bracket geometry
• - strong reduction of weight
• - Suitability also for extremely thin ropes (smaller than 7 mm diameter)
• - Combination of 2 system characteristics in the field of protection devices: "Normal" tuber z. B. ( EP 1971407 ) with round wire hanger and a belay device analog DE 10 2011 101 930 without hanger
• - The safety device according to the invention has a very short lever
• - The bar has a new function: it no longer serves only as a holding or positioning bar, but also as an operating bar, which also serves to lock and unlock the brake function
• - The release must be done actively in the safety device according to the invention
