Definitions

  • the sliding body runs along a flat braking surface, whereby a control lever with an eccentric braking surface is pivotably arranged on the base plate opposite the braking surface of the sliding body, which is pressed against the braking surface on the sliding body in the direction of travel when it is carried along by the rope and thereby brakes it EP-0 046 891 A2 (Fig. 7) is known.
  • a disadvantage of this abseiling device is that a spring (reference number 66) is required in order to always press the control lever so strongly against the rope that - especially if the person to be abseiled or the like as a result of fainting. lets go of the control lever - self-braking is guaranteed even without the intervention of a person. This spring needs a functional test at regular intervals.
  • Another disadvantage is that fine control of the sinking speed is difficult because it has to be done by counter pressure against this self-clamping force. This must be dosed very precisely by the operator himself. Otherwise there will be a jerky shutdown.
  • This sliding body has a braking surface with which a control lever cooperates, which is pivotably arranged on the base plate and which also has a braking surface.
  • the rope is guided over this braking surface of the control lever, for example along a circumferential angle of 90 °.
  • the weight of the person to be roped causes the control lever on the base plate to pivot so that its eccentrically running braking surface presses the rope with sufficient force against the braking surface of the sliding body.
  • the rate of descent is regulated in that the control lever 3 is pressed by a person against the direction in which it is rotated by the rope passing through the device.
  • a disadvantage of this device is that the entire weight of the person to be roped (in both types of use) loads the pin, about which the control lever is pivotally arranged on the base plate. If this point breaks, the person falls because he is attached to this connecting element with his full weight.
  • a rappelling device which has a sliding cylinder fixedly arranged on the base plate and a further sliding body which is movably arranged and at the same time acts as a control lever.
  • This sliding body has two cams, one of the cams pressing the control lever when the control lever rotates as a result of being entrained by the rope, or the other cam pressing the control lever against the direction of travel of the cable against the direction of travel of the cable and braking it in the process.
  • the person to be abseiled hangs on the base plate; it is disadvantageous, however, that the weight of the person to be abseiled is required so that the base plate and also the sliding bodies assume the vertical position required for the functioning. Only when this weight becomes effective, whereby the weight of a small child should not be sufficient for this, is the desired self-locking possible when the control lever is completely released in dangerous situations. Otherwise, the frictional force of the cable comprising the rotatably articulated control lever is not sufficient to push it against the force of a spiral spring (reference numeral 64), which pushes it in an opposite direction, into the position of self-holding.
  • a spiral spring reference numeral 64
  • Another disadvantage of this device is that the pin with which the control lever is articulated on the base plate has to absorb a very high force. This is a dangerous vulnerability, especially if the device has been left unused for a long period of time.
  • the device is difficult to handle, because without the weight of the person to be abseiled pulling on the rope causes the device to turn clockwise out of its position. It is therefore absolutely necessary that the rate of descent is additionally checked or secured by gripping the rope.
  • the invention is therefore based on the object of providing a descender device in which both the sinking speed can be finely adjusted on the one hand and on the other hand automatic braking occurs when the control lever is released.
  • the device should be constructed in a particularly simple and interference-free manner and be adaptable within certain limits to a change in the diameter of the rope, such as occurs, for example, as a result of moisture absorption or after the rope has been stretched due to heavy loads. Overall, there is a need for greater operational safety and simplicity.
  • control lever By designing the control lever with two cams and arranging it in relation to the concave area of the sliding body, two operating modes are possible: Either the operator (in an application, this is the person rappelling himself) presses the control lever against the frictional force exerted by the rope running past on the control lever that one of the two cams presses the rope into the concave area of the sliding body. Then the operator has it in his hand to regulate the speed by changing his pressure. This regulation can be metered very finely.
  • the descender according to the invention is also characterized by an extraordinarily great simplicity in structure and operability. It is also particularly easy to adapt to different rope diameters by replacing the control levers with appropriately adjusted cams.
  • FIG. 1 has a housing 1, formed by a base plate 2 and edge parts 3.
  • the housing is open in FIG. 1; the lid 4 is opened. It can be folded over to the right in FIG. 1.
  • the closure takes place in that a knurled screw 5 is screwed into the thread 6 (see also FIG. 3).
  • the base plate 2 has a first opening 7 at the top and a second opening 8 at the bottom, which are used for various types of abseiling.
  • the edge parts 3 have a first opening 9, a second opening 10 and a third opening 11.
  • a fixed sliding cylinder 12 is provided in the housing.
  • a further fixed sliding body 13 is also arranged above the sliding cylinder 12. It has an approximately teardrop shape, has a lower convex surface area 14 and an upper or laterally arranged concave surface area 15.
  • the control lever 19 can be pivoted about a pin 21 and has two cams 22 and 23 at its end which faces the concave surface region 15. These cams result from the fact that at these points the distance of the rounded surface of the end of the control lever 19 from the axis of the pin 21 is larger than in the adjacent area.
  • the arrangement is such that when the control lever 19 is pivoted downwards or upwards, the cams 22 or cams 23 move towards the concave surface area 15 such that the distance between the respective cam and the concave surface area becomes smaller.
  • the two cams 22 and 23 are arranged approximately opposite one another with respect to the pin 21. This is not strictly to be followed; it is essential that between the two cams a surface area of the control lever 19 is opposite, the distance from the axis of the pin 21 is noticeably smaller than that of the surfaces of the two cams 22 and 23.
  • the rope 16 lies in FIG. 1 in the housing 1 in such a way that a "descent on the rope" takes place.
  • the person to be roped hangs in a rappelling belt 17, which is hooked into the opening 8 in the base plate 2 with the aid of a snap hook 18.
  • the rope runs from below through the opening 11 into the housing 1. It is then guided over the sliding body 13, first over the concave surface area 15 and then - after a deflection by approximately 180 ° - around the convex surface area 14. 4-circle) the cylindrical sliding body 12 and therefore runs up through the opening 9 out of the housing 1 again.
  • the rope runs on two levels. As can be seen from Fig. 2, the bottom of the base plate 2 is formed obliquely so that the run of the rope from the uppermost point A, where it is diverted to the sliding body 13, to the point B, where it is around the bottom Sliding cylinder 12 rotates, in a direction perpendicular to the plane of FIG. 1, shifts down a rope diameter.
  • the person who is abseiling presses the control lever 19 upward, approximately until it is parallel to the dash-dotted line L. Then the distance between the concave surface area 15 of the sliding body 13 and the surface area 24 of the control lever 19 is such that the cable 16 can pass between the sliding body and the control lever without being trapped. It then runs up to point A, is deflected there, runs around the convex surface area 14 of the sliding body 13 and then around the sliding cylinder 12 and from there up through the opening 9 out of the housing 1. The rope is braked along its movement around the sliding body 13 and around the sliding cylinder 12, although not to a standstill.
  • the individual surfaces must of course be matched to the expected weight of a person to be abseiled in such a way that the weight is strong enough in the position L of the control lever 19 to bring the rope straight through the descender at a desired descent speed; the surfaces must be determined in such a way that when the control lever 19 is in position L, braking is taking place so that the cable runs through the device at a certain steady, not too high, even speed. Giving in on the control lever 19 in such a way that it can turn clockwise leads to a fine regulation.
  • FIG. 4 shows a further possibility for inserting the rope in such a way that the abseiling device is fastened at a specific fixed point by means of a crab 25 which passes through the opening 7 on the abseiling device.
  • the rope 16 now runs both from below into the device and down again out of the device. In principle, both directions of the rope run are possible.
  • the rope runs in from below through the opening 10 is then routed H times around the sliding cylinder 12; the rope then runs first around the convex surface area 14 of the sliding body 13 and then around the concave surface area 15 and down again out of the opening 11 out of the device. It becomes effective by frictional force on the cams 23 of the control lever 19 such that it is pivoted in the counterclockwise direction, so that the distance between the cams 23 and the concave surface area 15 of the sliding body 13 is reduced and the cable is clamped.
