Definitions

  • the invention relates to a catching device for a climbing protection system to prevent a user from falling off a ladder, a platform or the like.
  • the safety device runs in a guide rail and the user to be secured is connected to the safety device by a safety harness.
  • the fall arrester has a slide which runs in the guide rail, as well as a pawl which is rotatably mounted in the slide and, in the event of a fall, bumps against catches in the guide rail, and a fastening device for securing the safety harness to the pawl, the Fastening device has a damping element which mitigates the impact impact in the event of a fall.
  • Such a catching device is known from EP-A-0 168 021, DE-A-27 36 037 and DE-A-19 61 757. It is also known to provide a damping element in the fastening device in that a U-bracket hangs on a fastening ring of the pawl, on each of the two legs of which a damping element is seated. The free ends of the stirrup legs are closed by a plate. A plate is also provided above the damping elements and is displaceable on the bracket legs. A bolt is fastened to this plate, which extends axially parallel to the stirrup legs and does not extend downward between them and at its free end there is a fastening eyelet on which means of a snap hook the harness is attachable.
  • this fastening device In the event of a fall, the impact shock is guided over the bolt onto the top of the damping elements and the two damping elements are compressed, thereby reducing the impact impact.
  • the overall length of this fastening device is relatively large, however, and because the U-bracket and the snap hook each hang in a fastening eyelet, the fastening device has a great deal of play overall.
  • the invention has for its object to provide a Fangeinrich ⁇ device with damping element, in which the fastening device takes up as little space as possible and no more eyelet connections are provided than necessary.
  • this object is achieved in that the damping element is seated on a peg-shaped extension of the pawl, that a crosspiece is guided above the damping element on the peg-shaped extension and rests on the damping element, the harness being attachable to the crosspiece, which Cross piece is part of a shackle ring and the two ends of the cross piece are the steering knuckles on which the eyes of the shackle bracket sit.
  • the damping element is preferably a tube with a length of approx. 23 mm, an inner diameter of 12 mm and an outer diameter of approx. 24 mm made of a Fibroflex ® round rod with a hardness of 90 Shore A (yellow), as supplied by the company Fibro GmbH, 74 855 Hassmershei, FRG, under the order no. 253.6.025 is available.
  • An embodiment of the invention is shown below with reference to the drawing. Show it:
  • Fig. 1 the capture device in side view
  • Fig. 2 the catching device in a view from behind.
  • the guide rail has the C-profile known from DE-A-0 168 021 with guide lips which serve as guide flanges.
  • the carriage 1 has guide grooves 2 on both sides, which receive the guide lips of the guide rail.
  • Guide rollers 3 protrude into the guide grooves 2 and roll on the outside and inside of the guide lips.
  • the carriage 1 has a slot-shaped opening 5, in which a pawl 6 is rotatably mounted on a pin 7.
  • the nose 8 of the pawl 6 protrudes forward from the carriage 1 and into the interior of the C-profile of the guide rail so that the nose 8 abuts the catches.
  • the pawl 6 is supported at its upper end by means of the pin 7 and the back 9 of the nose 8 is chamfered downwards from the pin bearing.
  • the pawl 6 is under the action of a compression spring 10, which presses above the journal bearing 7 against the pawl 6, so that the nose 8 protrudes as far as possible from the slide 1. If the carriage 1 is pulled up by the user, for example when climbing a ladder, the back 9 of the nose 8 runs from below against the catch pegs and is pushed back due to its bevel so that the catch pegs are run over. Since the cone-shaped projection 11 points downwards and lies clearly below the journal bearing 7, the nose 8 dips into the carriage 1 when over the safety belt and the shackle ring 15 an upward pull is exerted on the peg-shaped extension 11.
  • the pawl 6 also protrudes from the slot-shaped opening 5 to the rear, i.e. towards the user and there is provided with a cone-shaped extension 11.
  • a vortex or crosspiece 14 which has an eyelet in the middle for receiving the neck 11.
  • a washer 19 is inserted between it and the crosspiece 14.
  • a stop disk 20 is fixedly arranged over the crosspiece.
  • the two lateral ends of the crosspiece 14 are designed as steering knuckles of a shackle ring 15, the two eyelets 16 being seated on the steering knuckles at the ends of the shackle bracket 17.
  • the safety harness or rescue harness of the user is attached to the shackle bracket 17 by means of a karabiner 18.

Abstract

Ce dispositif d'arrêt contient un chariot (1) guidable dans le rail de guidage, un cran d'arrêt (6), monté rotatif dans le chariot (1) et qui tourne à l'encontre de cliquets d'arrêt dans le rail de guidage, en cas de chute, ainsi qu'un dispositif de fixation permettant de fixer la sangle de retenue au cran d'arrêt (6). Le dispositif de fixation comporte un élément amortisseur (12), qui atténue l'impact en cas de chute. L'élément amortisseur (12) se trouve sur une partie saillante (11) en forme de tourillon du cran d'arrêt (6). Entre l'élément amortisseur (12) et le chariot (1), il est prévu une pièce transversale (14) montée sur la partie saillante (11) en forme de tourillon, à laquelle la sangle de retenue peut être fixée. La pièce transversale (14) constitue une partie d'un anneau de manille (15), les deux extrémités de la pièce transversale (14) se présentant sous forme de tourillons sur lesquels se trouvent les ÷illets de l'étrier de manille (17).
