Abstract

Via ferrata carabiner with a hook-shaped base body GK, on which a locking lever SN is pivotably mounted as a catch about an axis A1, serving to close a hook opening EH for a safety rope, and a locking lever SH pivotable about an axis A2 and mounted opposite the locking lever SN, which interacts with an elongated hole LL provided on the locking lever SN in such a way as to serve as a palm lock to prevent unintentional opening of the locking lever SN, with an opening Ö1 provided in the base body GK for a webbing loop B, characterized in that a clearance FR for two openings Ö1, Ö2 is provided between the locking lever SN and the locking lever SH in the lower section of the base body GK, wherein the opening Ö1 is arranged below the connecting line VL of the two axes A1, A2 and is designed as a narrow opening for a webbing loop B, and wherein an additional wider opening Ö2 is arranged above the connecting line VL, which serves to hook another via ferrata carabiner, wherein the connecting line VL is approximately perpendicular to the The main pull direction HR of the carabiner is where both openings Ö1 and Ö2 remain free even when the via ferrata carabiner is activated.

Description

The invention relates to a via ferrata carabiner according to the preamble of claim 1. Via ferrata carabiners have long been used to secure climbers on via ferratas, in conjunction with via ferrata sets. Via ferrata sets typically consist of a lanyard assembly with an energy absorber and two arms in a V-shaped configuration. The free ends of the two arms of the via ferrata set are fitted with the via ferrata carabiners, which are clipped onto a wire rope that serves as the safety cable on the via ferrata. The energy absorber is usually connected to the climber via a belay loop, for example, via a harness. Classic via ferrata carabiners are very similar in design to "normal" carabiners. Like them, they have a gate that closes a hooking hole on the body. However, they usually have a locking mechanism in the form of a sliding sleeve, which is easy to operate. For easy clipping onto the wire rope, via ferrata carabiners have a wider gate opening than normal carabiners, which is opened or covered by the gate. Special requirements must be met for via ferrata carabiners. Certification therefore follows a specific procedure. Standard (EN 12275) ), the standard for mountaineering carabiners, in particular according to clause “K” of this standard. On via ferratas, intermediate anchors are common, but these do not always ensure ideal force transfer to the carabiner under load. Therefore, a specific standard, the UIAA standard for via ferrata carabiners, requires an additional bending test to demonstrate increased strength under adverse loads. Newer versions of via ferrata carabiners feature a so-called palm safety device, which is designed to prevent the gate from opening unintentionally. The palm safety device consists of a locking lever that the user must activate with the palm of their hand before opening the gate. Some via ferrata carabiners, in addition to the large attachment point for the wire rope, have a separate, narrow opening for a webbing loop. This webbing loop can be attached, for example, to the end of a lanyard on the via ferrata set. Within this narrow opening, the webbing loop is well protected from external influences and is virtually impossible to shift unintentionally. Such a carabiner is available, for example, from... FR 2 805 577 A1 known. From the WO 2018/107 194 A1 This is a known safety carabiner with two eyelets, for a safety rope and a sling carabiner. The two eyelets are located next to each other. From the EP 2 532 394 A1 A carabiner with a strap opening is known, which is partially covered when the carabiner is actuated. From the EP 2 083 926 B1 A self-belay set with two connected via ferrata carabiners is known. AT 013 124 U2 represents a further state of the art. Typically, when climbing a via ferrata, both carabiners are clipped into the cable. However, there are situations where only one of the two carabiners can be attached to the wire rope. In this case, the second carabiner either dangles loosely from the climber or is attached to their harness, which is often covered by clothing. A loose, dangling carabiner is very cumbersome and requires a longer movement sequence before the carabiner is readily accessible and can be used. The same applies to a carabiner attached to the harness that is covered by clothing. In both cases, the carabiner not clipped to the wire rope is no longer visible to the climber, making it difficult to reach. The current development trend for via ferrata carabiners is towards a compact design and low weight, while considering good handling, functionality, material consumption, and a small number of parts. In particular, the overall length of the via ferrata carabiner along its main direction of pull should not exceed certain limits. The object of the invention is therefore to provide a via ferrata carabiner that meets the above-mentioned requirements of current development trends and at the same time does not have the aforementioned disadvantages, which in particular enables the quick attachment of a second via ferrata carabiner that is not needed due to the situation and which offers a certain degree of protection for the webbing loop. This problem is solved by the features specified in claim 1. The main idea of the invention is to provide a separate second opening on the base of the via ferrata carabiner for a second via ferrata carabiner, without increasing the length of the via ferrata carabiner. This requires sufficient free space on the base body. The first opening, which is intended for the webbing loop, remains free when the via ferrata carabiner is operated. The via ferrata carabiners can preferably be used with via ferrata sets. The invention is explained in more detail below with reference to an embodiment shown in the drawing. They show: 1 conventional via ferrata carabiner with a separate opening for a webbing loop, in accordance with the state of the art. 2 carabiner according to the invention 3 Via ferrata set with standard via ferrata carabi
