Definitions

  • the object of the invention is to further develop a descender of the type mentioned at the outset in such a way that the requirements mentioned are met, the focus being on the requirement for greater operational reliability and simplicity.
  • this object is achieved in that the sliding body in the direction of travel of the rope has a concave surface area, and the pivotable end of the control lever provided with two cams is arranged opposite this.
  • control lever with the cams is easy to replace, since it is a simple and easy to assemble part. This part can be replaced if you want to insert ropes with very different diameters.
  • the device works with a changing or not very different diameter, since the rope always runs along the concave surface area of the sliding body is that it always takes a cam of the control lever by frictional force in such a way that self-braking occurs by pinching.
  • 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 cam 22 or the cam 23 does not move onto the concave surface region 15 such that the distance between the respective cams and the concave surface region 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 there is a surface area of the control lever 19, the distance from the axis of the pin 21st is significantly less than that of the surfaces of the two cams 22 and 23, respectively.
  • the rope 16 lies in the housing 1 in such a way that "descent on the rope" takes place.
  • the person to be abseiled hangs in a rappelling belt 17, which is suspended in 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 about 180 - around the convex surface area 14. Then the rope 16 loops about an angle of 270 ° (3/4 Circle) the cylindrical sliding body 12 and therefore runs upwards out of the housing 1 through the opening 9.
  • the person who is abseiling presses the control lever 19 upward, approximately until it is parallel to the dash-dotted line L shown. 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 3/4 around the sliding cylinder 12 and from there upwards 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 areas must of course be matched to the expected weight of a person to be abseiled so that the weight is strong enough to bring the rope in the position L of the control lever 19 straight through the descender at a desired descent speed; the surfaces must be determined so 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 snap hook 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 opening 10 is then passed 1 1/2 times around sliding cylinder 12; the cable 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 that this is pivoted counterclockwise, so that the distance between the cam 23 and the concave surface area 15 of the slider 13 is reduced and the cable is clamped.
