    The invention relates to a semi-automatic device for securing the rope in top rope climbing. &Quot; climbing " has changed a lot in recent years. Formerly a means to an end for reaching the highest points of rock walls or mountains, the idea of free-climbing has developed parallel to this during the last century. However, it is not, as is often wrongly believed, climbed without any backup, however, the tools used quite useful such as ropes, hooks or carabiners serve only the backup and not the movement in the vertical. Thanks to the construction of numerous climbing sharks, this type of climbing has developed from a marginal to a mass sport.
    Basically, two people are involved in climbing a sport climbing route or climbing wall: the climber and the belayer. There is a distinction between climbing in the lead and climbing with toprope. In the former case, the climber will periodically hang the safety rope in interim backups or '' express loops ''. on the wall, from where it hangs down to the belayer. In toprope climbing, the climbing rope runs from the belayer to the top of the climbing route where it is deflected and comes in " from above " to the climber.
    If the climber rises, the length of the rope between him and the belayer shortens. The latter can assist the climber in climbing by tensioning the rope. When the climber reaches the end of his racetrack, he is released by the belayer at dosed speed to the starting point. However, the climber crashes during ascent, i. If it slips off the wall, the belayer catches the fall by fixing the rope. In doing so, he can either use suitable securing knots in climbing ropes or technical aids, e.g. a device that either automatically locks the rope under load or at least significantly reduces the holding force. -1 -
    According to the state of the art numerous safety hooks are on the sides, among other things, especially for sports climbers, known. Thus, EP 958.845 A2 describes a safety device for toprope climbers, i. for operation by a securing person, the rope being moved over several pulleys, i. a rope brake, is deflected at the top of the climbing route. In one direction of the rope, a general freewheel is provided in the other direction blocks at least one of the rollers, so as to achieve a braking effect.
    WO 95/16496 A1 describes an automatic belay device, i. without involvement of a security person, for attachment to the top of climbing walls. The device comprises a pulley which is connected via a one-way clutch with a descending speed of the climber to a few meters per second controlling viscosity brake. For additional protection, an optional centrifugal brake is provided. A load calibration device which is mountable at the top of a climbing wall or at the bottom is described in GB 2,470,370A. The device detects the necessary traction and accordingly automatically pulls the rope taut during ascent. Also, the automatic climbing aid disclosed in US 4997 064 A for mounting at the top of a climbing route automatically pulls the rope taut by means of a counterweight. DE 200 12 018 U1 discloses a to be mounted on the ground or at the upper end of the Velcro wall, operated by an electric motor climbing cable for toprope climbers, which can be remotely controlled by the climber via radio.
    US 4,458,781 A discloses a device using a ratchet / pawl and centrifugal brake system. The device is mounted at the top of a wall and works automatically.
    From CN 86209573 U a descender for the rescue of persons of buildings is known, which uses the braking effect of a differential band brake. A similar device with band brake is disclosed in DE 27 37 175 A1, wherein the band brake can be released by means of a lever. Further embodiments of rescue equipment with -2-
    Band brake are known from US 6,622,443 A, US 4,679,656 A and DE 29 10 573 A1. US 6,814,186 B1 also describes a device for controlled rappelling of weights, e.g. also persons when climbing, using a fluid brake, with a nonskid connection between the rope and pulley is ensured by ribs. From AT 400.927 B an automatic rescue and descender with a braked by adjustable centrifugal brake cable drum is also known, optionally an additional brake can be provided, preferably an adaptable to the body weight of the abzuseilenden person band brake, which is releasable by means of a lever, or a disc or drum brake. By means of a rewinding spring the rope is rewound after discharge. For the type of Toprope Klettems described above, in which a person standing on the ground operates the climbing rope which is deflected at the upper end of the wall and secures the climber, embodiments in which the rope is automatically wound onto a roll are of course out of the question. Therefore, the devices described in EP 958.845 A2 and DE 200 12 018 U1 are relevant from the above patent literature. However, these have serious disadvantages.
    The device according to EP 958.845 A2 develops a braking effect only by blocking one or more deflection rollers of the rope brake at the upper end of the wall, i. by friction of the rope on the blocking roller (s). However, this solution is not a sufficient backup for the climber, since the emphasis of the climber in a fall continues to be held by the belayer. In addition, the stress of the rope is very strong, which significantly reduces its reliability and service life.
    The device disclosed in DE 200 12 018 U1 comprises an electric motor for winding, which is why a power connection must necessarily be present, so that the device can hardly be used on climbing walls outdoors. In addition, there is a risk in the event of a power failure that either no protection against Ab- -3- ··········! * · · * * * * * · · · · · · · · ····· · >.,; ··· ··· ι > * ······ I ». * ··································································································································································· The same applies to the transmitter: If the battery is exhausted, the system will no longer work as planned. As a rope brake is preferably used that of the above EP 958.845 A2, which, however, as mentioned above, does not ensure sufficient safety. Another feature mentioned in DE 200 12 018 U1 is that the rope can be easily removed from the device and operated by a security guard, thus achieving the state described for EP 958.845 A2.
    Against this background, the aim of the invention was the development of a rope safety aid for toprope climbers, which is operated or regulated by a security person and offers greater security for the climber.
    DISCLOSURE OF THE INVENTION
    This object is achieved by the present invention by providing a semi-automatic device for safety rope in toprope climbing, comprising: a frame or housing for mounting the device on a climbing wall, preferably near the ground; a sheave for guiding, conveying and deflecting a safety rope, which is supported on a shaft rotatably mounted on Gesteli / in the housing and having a guide groove for the Sicherungsseii; a self-locking Differentiaibandbremse whose braking effect on the shaft by means of an operating lever is manually controlled; and a self-locking centrifugal brake, which is independent of the differential band brake braking action on the shaft in response to their speed is automatically triggered.
    The device of the invention operates semi-automatically, i. During a downward movement of the climber she exerts an automatic braking action on the shaft and thus on the climbing rope through the differentiaiband brake. However, the braking effect is adjustable by the belayer by partially releasing the band brake with the control lever. -4 In the event that the braking effect is thereby reduced too much, e.g. due to inexperience of the belayer or due to an event preventing him from the proper operation of the control lever, an additional safeguard ('deadman device', 'panic function') in the form of the centrifugal brake is provided, which engages at a certain number of revolutions of the shaft and the Rope slows down. Preferably, the centrifugal brake at a certain speed even blocks and thereby stops the downward movement of the climber, which ensures that the brake can be made smaller than a non-self-locking embodiment. The device of the present invention thus provides a significantly higher level of safety for the climber than the prior art.
    Under " self-locking " is to be understood for the purposes herein that the braking effect is independent of an external actuation and thus brakes shaft and rope. This applies according to the present invention for both brakes, of which the centrifugal brake of the device according to the invention, however, in preferred embodiments also also "self-locking". is, i. that the rotation, in contrast to conventional centrifugal brakes, which slow down the shaft only to a lower speed, but do not stop, is stopped abruptly when reaching a certain speed. How this is achieved will be explained later.
    In the device according to the invention, the rope is deflected over a pulley with a guide groove upwards. The normal force occurring between the rope and the sheave is increased by the geometry of the groove so far that a sticking of the rope to the sheave and thus a stable transport of the rope are guaranteed. In normal operation, there is no relative movement between the rope and pulley. In contrast to the prior art, where the braking effect is sometimes due solely to the friction between the cable and several pulleys, i. based on the principle of a simple cable brake, this sliding friction according to the present invention, due to the presence of two additional brakes, not only not required, but even undesirable. Due to the absence of large frictional -5-
    Relative movements between climbing rope and the device according to the invention, the wear on the device decreases and at the same time increases the life of the climbing rope compared to the prior art considerably. All parts of the device are mechanical in nature, so that no electrical power is required for the operation of the device.
    Under " mounting the device on a climbing wall " herein is to be understood both a direct mounting on the wall, wherein the frame or housing is preferably adapted for vertical mounting, as well as a mounting immediately in front of the Velcro wall, i. on a desk anchored on the floor or directly on the floor. In the latter case, the control lever should be designed to control the differential band brake correspondingly long to be comfortable and reliable to be operated by the belayer.
    Although the device according to the invention can also be at an elevated position at or immediately in front of the hook and loop wall, e.g. be mounted on a natural plateau or an artificial platform, if the circumstances require it, but preferably the mounting and fixing takes place near the ground. In climbing gyms, it is preferably mounted on the climbing wall itself, as this usually represents the simplest and most stable way of fixing. On natural climbing walls in the open, however, will be more preferable to a floor assembly.
    Preferably, the device is mounted on the wall at a height of between about 50 cm and 150 cm, more preferably between about 80 cm and 120 cm, on the one hand to provide convenient and reliable operation of the lever with sufficient force also from smaller persons, e.g. Children, but on the other hand also to prevent smaller children, e.g. Infants or preschoolers who may undesirably ventilate the differential band brake.
    The rope is preferably deflected by the sheave at an angle of about 270 °, i. from an approximately horizontal position from the hand of the belayer to the -6-
    The sheave is guided around the sheave in the guide groove three-quarters of a turn before it detaches itself from the sheave and deflects at the upper end of the shroud wall. Depending on the mounting height of the device, size of the security person, the distance between the belayer and the device or the device and the wall and the height of the upper Seilumlen-kung, this angle can vary by a few degrees.
    The operating lever is preferably adjustable between a decoupled and a coupled position. That is, in order to ventilate the band brake, not only a simple pulling or pushing on the lever is required, but it is necessary to perform a previous additional movement of the lever in a further spatial direction, e.g. a rotation from a lateral or downward pointing to an upright position to first connect it to the brake. This effectively prevents inadvertent ventilation of the differential band brake.
    The type of coupling and uncoupling is not particularly limited. For example, the lever rod may have a central longitudinal slot and a lateral extension and so be designed to be displaceable along its longitudinal axis, so that the extension engages in movement of the lever in an upright position in a connected to the brake linkage or locks. Or the lever can be locked via a lock, i. a combination of pawl and ratchet wheel having e.g. allows rotation of the operating lever in an upright position, but locks against a downward rotation, which in turn exerts pressure on a linkage with the lever. After the climber has descended, the ratchet can be released and the lever can be turned back to the down-facing starting position.
    The guide groove for the safety rope is preferably V-shaped to ensure a slip-proof torque transmission. Alternatively or additionally, but for the same purpose, the surfaces of the guide groove have a profiling, i. they are, for example, roughened or provided with grooves, elevations, depressions or combinations thereof. -7-
    In preferred embodiments, the guide groove is also asymmetrical, in order to minimize the possible deflection of the cable entering the groove and the cable length expiring when the cable is preferably deflected by about 270 °. This asymmetry can be generated, for example, by making one side wall of the groove lower than the other and / or by increasing the opening angle of one side wall to the top edge thereof while keeping the other side wall the same. The latter is preferred according to the present invention.
    Not only, but especially if the guide groove of the sheave features promoting the rope's liability, e.g. Profilings, etc., is mounted on the frame or in the housing preferably a engaging in the guide groove guide member for promoting the detachment of the safety rope of the sheave. This guide element prevents the rope from winding around the sheave several times. The guide element engages particularly preferably in both directions of rotation of the pulley in the groove.
    In a further preferred embodiment, the pulley is mounted on the shaft with a freewheel in a rotational direction to allow easy retrieval of the rope as the climber climbs through the belayer, without the braked shaft rotates.
    In particularly preferred embodiments of the device according to the invention with a self-locking centrifugal brake, the centrifugal brake comprises a plurality of spring-biased flyweights comprising a friction surface within a brake drum, the flyweights being each mounted on a hub rigidly connected to the shaft, the curvature of the friction surfaces of an elliptical shape follows and the contact points between the elliptical friction surfaces and the brake drum are each substantially in line with the shaft and the pivot bearing of the respective centrifugal weight. -8th-
    Upon contact of the friction surfaces with the brake drum with a sufficient number of revolutions of the shaft, the resulting frictional force endeavors to additionally rotate the respective flyweight. If the centrifugal weight were circular, it would be further rotated by the friction force and the centrifugal brake would brake the rotation, but not block. However, with an at least slightly elliptical curvature, the normal force increases, which in turn increases the frictional force, etc. and eventually causes the brake to lock when the contact points between the friction surfaces and the brake drum are substantially in line with the shaft and pivot of the respective flyweight lie, and so bring the wave to a halt. The flyweight is "stuck" between the flyweight and the brake drum, so to speak. In this condition, the brake blocks until it is unloaded, e.g. by a short turn in the opposite direction, releasing the flyweights from the springs from the clamped position.
    In order to keep the transverse loads in the centrifugal brake low, the centrifugal weights, as usual, preferably arranged rotationally symmetrical about the hub.

DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION Generally, the drawings described in more detail below are schematic illustrations for illustrating the operation of the device according to the present invention, Dimensions, angles, etc. may differ.
    Fig. 1 shows in a frontal view (Fig. 1a) and a side view (Fig. 1b) schematically the situation when Toprope Klettem using a device according to the invention, which is housed in a housing 2, which is directly and near the bottom of a climbing wall is mounted, as is preferred according to the present invention. The climber is secured by a person on the ground via a climbing or safety rope 4, which is deflected at the top of the climbing wall 1 and runs from the top to the climber.
    The security person pulls in the rise of the climber rope and dosed down during the descent Since, taking advantage of the braking effect of the device according to the invention. • »• ·« «t *» # - t * _ · · * * * * * ·· ♦ · * · ·· t 4 · «» «#
    The not connected to the climber end of the climbing rope 4 is shown behind the belayer on the ground disordered, but can also be wound, for example, on a roll or wrapped around one or more rods, as long as it is guaranteed that it unwound sufficiently quickly in the orderly descent of the climber becomes.
    Fig. 2 is a vertical cross-sectional view of an embodiment of the device according to the invention. This comprises a housing 2, in which a shaft 5 is rotatably mounted. This shaft 5 carries a sheave 3 for guiding, conveying and deflecting the safety rope 4 and is braked by a differential band brake 7 and a centrifugal brake 9 (BR). The pulley 3 preferably has a V-shaped guide groove 6 for the cable 4, and the braking action of the differential band brake 7 is adjustable via an operating lever 8.
    The bearing of the sheave 3 on the shaft 5 is preferably carried out via a freewheel 19 (FL) in one direction, i. during the climb of the climber, when the person securing the rope pulls in the rope, the shaft does not rotate with the sheave 3.
    FIG. 3 shows a further vertical cross-sectional view of the device according to the invention, which is offset by 90 ° with respect to FIG. To recognize here is in turn carried on shaft 5 pulley 3, around which the cable 4 is guided around at an angle of about 270 °, which is preferred according to the invention to ensure the cable transport. In addition, parts of the differential band brake 7 are shown, namely a brake disc 7a, a brake band 7b and a lever 7c, which is connected to the operating lever 8 or connectable to thereby control the braking effect.
    In Fig. 4 is a front view of a particularly preferred Ausführungsfbrm the sheave 3 is shown. This embodiment has profiles in the form of elevations or webs 10 within the guide groove 6, which ensure a slip-proof transport of the rope around the pulley. Alternatively or additionally, the inner wall of the guide groove 6 may also be roughened, grooved, studded or the like. In all cases, such profilings are preferably provided around the entire circumference of the sheave, but may also be applied only in a partial area. In addition, it can be seen in Fig. 4 that the opening angle of the right side wall 6a of the guide groove 6 increases toward its upper edge while that of the left side wall 6b remains the same. This reduces the friction between the outgoing and incoming strands of the safety rope 4 when it is guided around the sheave at an angle of about 270 °, as shown here, since the two strands have more space to pass each other slide.
    Fig. 5 shows the same embodiment of the sheave 3 as Fig. 4, wherein in addition a preferred according to the present invention guide member 11 is mounted above the sheave on (not shown) housing. In Fig. 5a, the position of the two components is shown without inserted rope, the preferred course in Fig. 5b is indicated by dashed lines. Fig. 6 is a side view of the guide member 11 alone. As can be seen, the guide member 11 comprises a plurality, preferably integrally connected, parts: a guide surface 11a for the substantially vertically leaking strand, two guide surfaces 11b and 11c for the substantially horizontally leaking strand and a mounting plate 11d for attachment to (here not shown) housing or frame.
    In FIG. 6, it can be seen particularly clearly that the guide surfaces 11a and 11b are chamfered upwardly facing one another, while FIG. 5 makes clear that the guide surface 11c is in the direction of the upward-opening, widening side 6a of the guide groove 6 is bevelled.
    Above all, the guide element 11 prevents the climbing rope, which bears well on the sheave due to static friction, from wrapping around the sheave several times. The guide surface 11a comes while rappelling of the climber, i. on the upward movement of the rope 4, to the effect, the guide surfaces 11b and 11c, however, on the rise of the climber, i. on downward movement of the rope towards the security person. The inclined guide surface 11c also supports the displacement of the substantially horizontally leaking rope strand to the extending side 6a of the guide groove, which further reduces the friction between the rope strands.
    FIGS. 7 to 9 are illustrations of embodiments of the centrifugal brake as part of the device according to the invention. Fig. 7 shows a conventional self-locking, but not self-locking centrifugal brake. This is rigidly mounted on the shaft 5 via a hub 16. On the hub 16, two rotationally symmetrical centrifugal weights 13 are mounted within a brake drum 14 each have a pivot bearing 15 which carry on their outer side in each case a friction lining 12, which bereitsteilt the friction surface with the drum. However, instead of separate friction linings 12, the friction surfaces may also be formed directly on the flyweights, e.g. in the form of roughened, ribbed or otherwise textured surfaces.
    The centrifugal weights 13 are stretched by means of centrifugal force counteracting springs 18 to the hub 16, so that a spring tension exceeding centrifugal force is required to trigger the braking effect of this centrifugal brake.
    In the upper part of Fig. 7, a state is shown in which the rotation of the shaft is too slow to generate the necessary centrifugal force, so that the flyweight 13 is not applied to the inside of the brake drum. In the lower part, however, the state is shown with faster rotation, so that the brake pad of the flyweight rubs along the drum and thereby slows down the rotation and the number of revolutions in turn approaches the lower limit. In this way, a dependent of the spring tension, essentially constant rotation is generated.
    Due to the concentricity of the inner wall of the brake drum and the friction surfaces a substantially uniform braking friction over the entire surface of the brake pads is achieved, which is why this type of centrifugal brake can not block.
    The climber is by means of such an embodiment of the centrifugal brake - which, as mentioned above, is used only for the fold that the differential belt -13- · brake (for whatever reason) fails - roped at a constant speed.
    FIG. 8 shows a preferred embodiment of the differential band brake of the device according to the invention, again in the two mentioned rotational states. It consists essentially of the same components as those of FIG. 7 with the exception that the friction surfaces 12 are formed directly on the flyweights 13. Instead, however, the centrifugal weights could again wear separate friction linings. Essential to the invention, however, is for this preferred embodiment, on the one hand, the additional difference that the friction surfaces are not concentrically curved with the brake drum, but deviate from the circular shape, i. follow an elliptical shape. This can be seen particularly clearly in FIG. 9, which shows a detail enlargement of FIG. 8.
    As a result, the braking effect is not distributed over the entire friction surface, but is substantially at a point indicated by reference numeral 17, concentrated in the illustrated case the vertex of the ellipse. If this contact point 17 of the elliptical shape with the brake drum is substantially in line with the rotary bearing 15 and the shaft 5, the effect already described above occurs, and the flyweights "jam", i. the brake blocks until a (short) turn in the opposite direction takes place.
    The present invention thus provides a new toprope climber safety device which provides a significantly higher level of safety for the climber than conventional prior art rope safety devices. -14-
