Definitions

• the invention relates to a snap hook, in particular for mountaineers, with a C-shaped bracket, the ends of which can be connected to one another by a resilient pawl, so that there is a closed, elongated ring, on one narrow side of which engages a holding element and on the other narrow side of which Guide area is formed for a safety rope.
• Snap hooks of the specified type are used by mountaineers to secure the safety rope used in climbing to a more or less inclined rock face.
• the snap hooks are fixed at more or less long holding elements, mostly in the form of sewn loops made of flat band fabric, at securing points in the rock, such as hooks, clamping wedges or the like.
• the Holding elements of different lengths compensate for the deviations of the securing points from the straight line of the rope as much as possible, so that the rope is deflected as little as possible and can be easily tightened by the climber climbing ahead.
• the holding elements each engage on a narrow side of the snap hook.
• On the opposite narrow side of the snap hook is a guide area for the safety rope, around which the safety rope is pulled with great force in the event of a fall. For this reason, this guide area is usually rounded in section so that the safety rope can be deflected in the event of a fall with as little friction and wear as possible.
• a disadvantage of the snap hooks known from the prior art of the type mentioned at the outset is that in the event of a fall, the safety rope is clamped between the guide region and the rock wall with a relatively great force. The result is that the safety rope on the rough rock surface is worn and damaged, so that rope breaks can occur.
• the uncontrollable braking effects generated by pinching the safety rope also prevent timely response of the recently used dynamic braking device at the beginning of the safety rope.
• the braking device can therefore often use up the fall energy insufficiently, so that the risk of injury increases considerably.
• the invention proposes, starting from a snap hook of the type mentioned, that the elongated ring is formed with projections, bends or a twist that inevitably spend the guide area when the ring is placed on one level at a distance from this level.
• the measures proposed according to the invention ensure that the guide area is always at a distance from the support plane (rock surface). This distance is of course dimensioned so large that the safety rope can pass freely between the rock surface and the guide area. The safety rope can therefore no longer be clamped between the rock surface and the guide part and thereby damaged or worn. The uncontrollable braking effects caused by the pinching also no longer occur. If a dynamic braking device is used, it is thus ensured that this braking device comes into effect in accordance with the regulations.
• a first embodiment of the invention provides that the web of the C-shaped bracket is bent perpendicularly to the main plane of extension of the ring up and down. This ensures that the guide area is always kept at a distance from the rock wall, regardless of which one Side of the snap hook is supported on the rock wall.
• An alternative embodiment of the invention provides that the web of the C-shaped bracket and / or the pawl are thickened perpendicular to the main plane of extension of the ring.
• the attachment of such thickenings has the advantage that they can also be attached to existing snap hooks, for example by attaching appropriately shaped sleeves or the like.
• a third embodiment of the invention provides that the web of the C-shaped bracket is twisted about its longitudinal axis.
• This embodiment of the snap hook according to the invention has the advantage that the guide area is lifted off the rock surface at any position of the snap hook. Another advantage results from the fact that the pawl can be pivoted past the opposite web of the C-shaped bracket, so that there is a larger opening angle for the pawl and the safety rope can be hooked in more easily.
• Fig. 1 A snap hook according to the invention in side view
• Fig. 2 is a plan view of Fig. 1;
• FIGS. 1 and 2 shows a practical use case of the snap hook according to FIGS. 1 and 2;
• FIG. 4 shows a side view of a snap hook according to the invention in a second embodiment
• Fig. 5 is a top view of Fig. 4;
• FIG. 5 shows a side view of a snap hook according to the invention in a third embodiment
• Fig. 7 is a side view of Fig. 6; 8 is an end view of FIG. 6.
• the carabiner shown in FIGS. 1 to 3 has a C-shaped bracket 1, the web of which is designated by the reference number 2 and the ends of which can be connected to one another by a resilient pawl 3 to form a closed, elongated ring.
• the elongated ring has an upper narrow side 4 and a lower narrow side 5.
• On the upper narrow side 4 engages a holding element 6 (see FIG. 3), which is designed as a sewn loop made of flat strip material.
• the holding element 6 is in turn attached to a rock anchor 7 which is anchored in a rock wall 8.
• the lower narrow side 5 of the elongated ring 1, 3 is designed as a guide area for a safety rope which is guided around this guide area.
• the web 2 of the C-shaped bracket 1 is perpendicular to the head extension plane of the ring bent up and down.
• These bends 10 and 11 are designed such that the guide area on the narrow side 5 of the ring when the ring is supported on one level (surface of the rock wall 3) is necessarily at a distance from this level (cf. in particular the illustration in FIG. 3 ). This distance is greater than the thickness of the safety rope 9, so that the safety rope can freely run around the guide area on the lower narrow side 5 without being pinched between this guide area and the rock wall 8.
• the web 2 of the C-shaped bracket 1 is thickened perpendicular to the main plane of extent of the ring. These thickenings 20 and 21 also lift the guide area located on the narrow side 5 from the support level to the required extent.
• the pawl 3 can also be provided with corresponding thickenings in this exemplary embodiment. These thickenings on the web 2 or the pawl 3 can optionally be attached subsequently.
• the web 2 of the C-shaped bracket 1 is twisted about its longitudinal axis, so that here too the guide area located on the narrow side 5 is sufficiently lifted off a flat support surface.
• This embodiment has the be special advantage that the pawl 3 can be pivoted past the opposite web 2. In this way the snap hook can be opened further and the safety rope can be inserted more easily.
