Description
Seilkarabiner, insbesondere zur Verwendung mit Kletterseilen Den Gegenstand der Erfindung bildet eine be sondere Ausgestaltung eines Seilkarabiners. Es hat sich ergeben, dass der bisher verwendete, ovale oder keilförmige Querschnitt des Karabiners an den An griffstellen des Seils zur vorzeitigen Abnützung des Seils beitragen kann.
Um den Karabiner in dieser Hinsicht zu verbes sern, weisen erfindungsgemäss die Schenkelteile, an denen das Seil angreift, einen T-förmigen Querschnitt mit abgerundeten Umrisslinien auf, dessen Querbal ken als Seilauflage dient und der kontinuierlich in den ovalen oder runden Querschnitt der übrigen Teile übergeht. Dadurch wird bei gleicher Festigkeit eine vorzeitige Abnutzung des Seils verhindert.
Die Zeichnung veranschaulicht eine beispielsweise Ausführung eines solchen Karabiners. Fig. 1 zeigt den Karabiner von der Breitseite und Fig.2 von der Schmalseite gesehen. Fig. 3 ist ein Querschnitt nach Linie A-B der Fig. 1.
Während der Karabiner im Mittelteil 1 runden oder ovalen Querschnitt besitzt, sind die beiden Schenkelteile 2 und 2', an denen das Seil bei Anwen dung einer Zugkraft innen aufliegt, zur Bildung einer möglichst breiten Auflagefläche beiderseits bei 3 eih- gekerbt, so dass sich ein T-förmiger Querschnitt mit abgerundeten Umrisslinien ergibt. Die Dimensionen sind natürlich mit Rücksicht auf die erforderliche Biegefestigkeit gewählt.
Wenn eine einfache Stau chung des Querschnittes in die T-Form nicht aus reicht, kann der Querschnitt unter Zugabe weiteren Materials verstärkt werden.
Die durch den T-förmigen Querschnitt bewirkte Verbreiterung der Auflagefläche ist jeweils in der Mitte der Seilauflage am grössten. Anschliessend geht der T-Querschnitt kontinuierlich in den ovalen oder runden Querschnitt der übrigen Teile des Karabiners über.
Rope carabiner, especially for use with climbing ropes The subject of the invention is a special embodiment of a rope carabiner. It has been found that the oval or wedge-shaped cross-section of the carabiner that has been used up to now can contribute to premature wear of the rope at the points of contact on the rope.
In order to improve the carabiner in this regard, the leg parts on which the rope engages have a T-shaped cross-section with rounded outlines, the crossbar of which serves as a rope support and which merges continuously into the oval or round cross-section of the other parts . This prevents premature wear of the rope while maintaining the same strength.
The drawing illustrates an example of such a carabiner. Fig. 1 shows the carabiner seen from the broad side and Fig. 2 from the narrow side. FIG. 3 is a cross section taken along line A-B of FIG. 1.
While the carabiner in the middle part 1 has a round or oval cross-section, the two leg parts 2 and 2 ', on which the rope rests on the inside when a tensile force is applied, are notched at 3 on both sides to form the widest possible contact surface so that a T-shaped cross-section with rounded outlines results. The dimensions are, of course, chosen with the necessary flexural strength in mind.
If a simple compression of the cross-section into the T-shape is not sufficient, the cross-section can be reinforced by adding further material.
The widening of the support surface brought about by the T-shaped cross-section is greatest in the middle of the rope support. The T-cross section then merges continuously into the oval or round cross-section of the other parts of the carabiner.
