Definitions

  • the invention relates to a person descender device, consisting of a rope, one end of which has fastening means for fixed attachment to a part of the building and the other end of which is attached to a rope drum which is rotatably mounted in a frame, the frame has connection devices for a person carrying device, the cable drum is operatively connected to a brake which serves to regulate the abseiling speed and is under spring preload, the brake being operable during abseiling via a brake lever designed as a rocker and the brake lever on the one hand for manually releasing the brake via a first actuating element against the prestressing spring force and on the other hand for manually increasing the braking force can be influenced by a second actuator.
  • a personal descender of this type, from which the invention is based, is known from DE-B-2 646 368.
  • This known abseiling device ensures a constant abseiling speed without having to actuate the brake acting on the cable drum, but only if the brake acting on the cable drum has previously been adjusted to the body weight of the person to be abseiled.
  • the object of the invention is now to provide a personal rappelling device of the type specified in the preamble of claim 1 while maintaining the advantages already achieved in the prior art, which consist in the fact that the rappelling speed by the person to be rappeld during rappelling, if necessary, both to a standstill can be delayed as well as increased in such a way that simple means and measures can otherwise achieve a constant abseiling speed without having to adjust the brake beforehand to the respective body weight of the person to be abseiled.
  • the person to be rappelled is now weighed when the person carrying device is loaded and then the brake acting on the cable drum is automatically adjusted in accordance with the body weight of the person to be descended so that a constant rappelling speed is now ensured regardless of the body weight of the person to be descended.
  • the spring is designed as a compression spring in order to achieve a constant abseiling speed even if the spring breaks.
  • the aforementioned traction element is connected to the brake lever via a lever pivotably articulated on the frame.
  • a cable drum 2 is rotatably mounted about a frame-fixed axis 3 on an annularly closed frame 1.
  • the cable drum 2 is provided on its end face with a cylindrical recess 22 in which two brake shoes acting on the cylindrical outside thereof are arranged in a known manner.
  • the two brake shoes are pivotally connected about the pivot points 23 and 24 to a supporting part 25 which is fixedly connected to the frame 1.
  • the support part 25 is provided with a shoulder 26 in which a brake shoe actuation shaft rigidly connected to the brake lever 5 is rotatably mounted.
  • the latter is flattened on its side protruding from the extension 26, located between the two free ends of the brake shoes, so that when the brake lever 5 is pivoted, a corresponding actuation of the flattened part of the actuating shaft 5, which acts via its free ends, as a brake shoe spreading part Brake shoes is effected.
  • the lever arm 8 of the brake lever 5 is also connected to a second pulling element 10 in the form of a manually operable Bowden cable, with which the braking force of the shoe brake 4 can be braked manually to a standstill of the cable drum 2, for which purpose the brake lever 5 is pivoted clockwise.
  • the wire rope 11 fixed to the rope drum 2 with one end is guided in a known manner through the upper end part of the frame 1, and has at its free end, e.g. a snap hook, for fixing the free end of the rope to a suitable part of the building.
  • a person carrying device is attached at the lower end of the frame 1. Furthermore, the abseiling device is surrounded by a housing 12.
  • a sleeve 13 is fastened, in which a spring 14 designed as a helical compression spring is inserted so that its direction of action is perpendicular.
  • the lower end part of the spring is supported on the bottom of the sleeve 13.
  • a pulling element 15 designed as a head pin engages, the head of which is supported indirectly on the upper end part of the spring 14.
  • an eyelet 16 is screwed for connecting the person carrying device. By more or less screwing the eyelet 16 onto the shaft of the tension member 15, the spring preload of the spring 14 can be changed.
  • the head of the traction element 15 is gripped from the bottom of a fork piece 16 ', to which a one-armed lever 17 is articulated, the fulcrum 18 of which is articulated on the load arm of a second, two-armed lever 19 which is pivotably mounted on the frame 1.
  • the power arm of the lever 19 is connected to the tension member 9.
  • the load arm of the lever 17 is articulated to the lever arm 8 of the brake lever 5 via a variable-length coupling piece 20.
  • a return spring 21 is provided which is fixed to the frame and is effective on the tension member 9.
