Description

The invention relates to a device for securing a climbing rope with a receiving space for a cable loop having carrier body, and with a carrier body movably arranged looping part for the looped through the receiving space rope loop, the movement of which clamps the rope on the carrier body.

Such a device is for example the EP 398819 refer to. The local housing comprises two base plates, between which a fixed cable guide element and a pivoting loop part are arranged for a cable loop. The pivotable belt part has an eccentric and non-circular outer surface with respect to its pivot axis. Therefore, the gap between the fixed cable guide member and the pivotal wrap member changes when the wrap member is twisted about the axis, and the cable passed through the gap is clamped in the given nip. On Umschlingungsteil a release lever is provided, with the aid of the braking force can be controlled at the nip in order to run the rope controlled by the device.

On the housing, a carabiner can be hung, which is performed by two holes in the two base plates outside the pivoting range of the belt.

A disadvantage of the known systems is the one-sided "punctiform" clamping point in which the clamped cable section is subjected to a heavy load, which can lead to the usually unnoticed damage to the rope.

It is also known to use a hinged carabiner as a wrap. This leads to the FR 2836635 to two clamping points, as can be brought by a corresponding recess in the housing of the hinged carabiner sufficiently far to the side boundary of the inlet and outlet for the cable loop. However, it is problematic to use the carabiner as a wrap around, because on the one hand too small a loop of rope arises, the prevents easy insertion and removal of the rope, and on the other hand, the cross section of the carabiner has an influence on the braking and Ablassverhalten the safety device.

The invention has now taken on the task of further developing a device of the type mentioned without the use of a carabiner as a clamping element so that neither the rope nor the moving belt part are overloaded and damaged.

According to the invention this is achieved in that two spaced-apart clamping points for the cable loop are provided on the carrier body, and the loop part each has a clamping region for both terminal points.

This construction leads to a number of advantages, since the loop part can be chosen with maximum size and thus the curvature of the cable loop is lower. the clamping points can have rounded surfaces and even the thinnest, used during climbing ropes are clamped reliable. Preferably results in a (nearly) symmetrical clamping in both clamping points, which also the dreaded swapping of load cable side and Bremshandseilseite in the device can lead to no fatal consequences, as long as the brake hand holds the rope on the side not directly loaded. Since no carabiner is included in the safety and braking process, the most suitable materials such as stainless steel or titanium can be used for all parts in contact with the rope. The carabiner cross-section, which may be round, oval or triangular, plays no role in the braking behavior of the safety device.

The belt part is preferably spring-loaded so that it automatically returns to its rest position after a load suspension. Thus, a very easy cable input and output can be realized and the device must not be touched during the backup process, so that operating errors during the backup process are virtually eliminated. A touch is only required to deflate a climber.

The side boundaries of the receiving space for the cable loop are in particular by connecting bolts or rivets and possibly this enclosing Bushings or sleeves formed between a bottom plate and a cover plate of the carrier body. The wrap member may move substantially centeredly back and forth with respect to the two side boundaries so that the force distribution between the two nips is fairly balanced.

In a preferred embodiment, it is provided that the loop part is pivotable about an axis which is arranged outside of the receiving space for the cable loop. The pivot axis of the belt part is preferably located in a further connecting bolt or the like between the bottom plate and the cover plate of the carrier body in a position in the vicinity of a connecting line through the arranged on the Seilein- and -austrittsöffnung connecting pin. The further connecting bolt carries a pivotable strap, from which the strap part is upstanding. The space between the strap member and the connecting bolt is substantially larger than the diameter of the thickest rope to be inserted, so that the threaded into the receiving space rope loop can be easily placed around the swung-loop part. The belt part is preferably pivotable by at least 90 °, wherein the lug carrying it is aligned approximately parallel to the above-mentioned connecting line in the clamping of the cable loop and meets the Umschlingungsteil approximately at right angles to the two clamping points.

The belt part is preferably designed as a ring body and of the lowest possible weight, whereby it also has a very large central opening, which is also formed in the tab. If the diameter of the opening is greater than the pivoting of the belt portion between the clamping and the rest position, through openings for a carabiner can be provided in the bottom plate and in the cover plate of the carrier body. If a carabiner hooked at this point in the housing, so he also passes through the much larger central opening of the enclosure part, wherein he touches the ring body neither in the clamping nor in the rest position. A carabiner thus does not hinder the pivoting of the belt part and can therefore always be moved or swung back and forth. The arrangement of the carabiner within the pivoting range of the enclosure part contributes to a compact and handy size of the security device.

The safety device according to the invention thus has an excellent and thanks to the division into two clamping areas yet material-friendly braking effect in a fall into the rope. The clamping areas are provided in particular offset by about 250 ° on the circumference of the belt portion. For controlled dispensing and retrieving the unloaded rope of Umschlingungsteil is in particular spring assisted pivoted back into the rest position and so far away from the clamping points that the rope can be easily pulled through.

For a controlled rope feedthrough under load, in particular when deflating a climber, intermediate positions are necessary, which allow a smooth adaptation of the braking forces. In preferred embodiments, it is therefore provided that the wrap-around part has a release extension projecting substantially in extension of the strap, and that the detachment extension of the wrap-around part is assigned a release lever pivotable about an axis. The release lever is preferably two-armed, whereby the lever arm to be gripped by hand must perform a rotational movement directed away from the operator in order to loosen the loop part. This movement, however, results especially only with concentrated exercise, but not in an unconcentrated panic case. Even a reflexive gripping or squeezing the hand in a panic case would not trigger a release of the climber. A right-handed and left-handed arrangement of the release lever has been taken into account so that unnecessary operator complications can be avoided. Preferably, the release lever is spring-loaded, so that it returns to its basic position abutting the base body after actuation.

The invention will now be described in more detail with reference to the figures of the accompanying drawing, without being limited thereto.

A device for securing a climbing rope 3 has according to Fig. 1 or Fig. 6 a carrier body 1, which is provided with a receiving space 2 for a cable loop 4. Next an inlet and outlet opening 10 in the receiving space 2, two opposing clamping points 11, 12 are provided, in which the cable loop 4 is clamped in overload, for example, fall of hanging on the load cable side 13 climber in the cable 3 and blocked. This is achieved in that the cable loop 4 is guided around a movable loop member 15, on which two opposite clamping portions 21, 22 are formed, and in the approach to the clamping points 11, 12 of the inlet and outlet opening 10 opposite side shrinks the passage space for the rope 3 in two clamping points 11, 12 and the rope clamps there and brakes or stops.

The movement of the wraparound part 15 is in the first embodiment Fig. 1 to 5 a pivoting movement about an axis 16 arranged outside the receiving space 2 for the cable loop 4 and in the second embodiment a displacement in the direction of the arrow 20 (FIG. Fig. 6 ). In this way, an approximately equal clamping in both clamping points 11, 12 is achieved, wherein the division into the two mutually distanced clamping points 11, 12 substantially contributes to the avoidance of damage to the rope 3.

In the execution after Fig. 1 to 5 is the support body 1 like a housing constructed of a bottom plate 7 and a cover plate 8, which are held by fasteners 9 in the form of bolts, grooves or screws, etc. at a distance from each other.

The connecting elements 9 are preferably surrounded by bushes or sleeves. Two connecting elements 9 limit the inlet and outlet opening 10 for the cable loop 4 and each form the fixed clamping region of the two clamping points 11, 12. The bottom plate 7 and the cover plate 8 each have an opening 6, through which a carabiner 5 (FIG. Fig. 1 ) and thereby can be suspended approximately centrally in the carrier body 1. Floor and cover plate 7, 8 may have honeycomb-like areas for weight saving, such as Fig. 1 shows.

Fig. 2 shows the carrier body 1 of the securing device without cover plate 8 and with around the axis 16 outwardly pivoted Umschlingungsteil 15, which has a arranged on a tab 17 annular body. The annular body has an opening 19 with a diameter which is substantially larger than the diameter of the opening 6 in the bottom plate 7. The wrap-around part 15, in continuation of the tab 17, has a release extension 18. Two approximately 110 ° on the circumference of the annular body spaced areas constitute clamping portions 21, 22 for the cable 3. On the opposite side of the support body 1, a release lever 25 is pivotally mounted about an axis 26 having an extension 27. The release lever 25 covers in the in Fig. 2 apparent rest position a substantial part of the carrier body 1 from the side.

Fig. 3 shows the strap member 15 in the pivoted-in rest position or release position, in which the cable loop 4 formed between the load cable side 13 and the brake hand side 14 is guided in the receiving space 2 without clamping around the loop part 15. In this position, therefore, the dashed line drawn rope 3 can be pulled through the safety device by pulling with one hand on the load cable side 13, which leads up to the climber, pulled with the other hand on the Bremshandseilseite 14 rope. In the rest or release position superimposed on the much larger opening 19 of the strap member 15, the opening 6 in the bottom plate 7; also in the braking or blocking position, the in Fig. 4 is shown. The pivoting of the belt part 15 is therefore not hindered when a carabiner 5 is suspended in the opening 6 of the carrier body 1.

As Fig. 4 shows further, the cable loop 4 has been attracted due to an overload on the load cable side 13 and has the wrap 15 in the Locking position pivoted, in which the cable 3 is clamped in two clamping points 11,12 between the connecting elements 9 and the clamping portions 21, 22 on the annular body. From the illustration in Fig. 4 It can be seen that the diameter of the cable 3 can also be substantially smaller and the device can therefore also be used with the thinnest ropes approved for practical use. In the in Fig. 4 shown position of the release lever 25 is unchanged and the extension 27 is swung out of the release extension 18 of the wrap 15.

In the in Fig. 5 shown intermediate position, the loaded rope controlled braked guided by the device by the release lever 25 is actuated and the extension 27 presses against the release extension 18 of the wrap 15. As a result, the clamping points 11, 12 open to a certain extent and the loaded rope is delayed pulled by the safety device, for example, to lower a rope hanging on the climber to the ground. The opening of the brake requires a deliberate operation of the release lever 25. If this movement is disturbed or interrupted, the wrap member 15 pivots back into braking or blocking position and the braking effect is enhanced by the load hanging on the rope.

In the execution after Fig. 6 the inlet and outlet opening 10 is provided in a round, tuber-like carrier body 1, in which the loop part 15 is linearly displaceable in the opening axis. The division into two clamping points 11, 12 is also given.
