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.
