Definitions

  • the invention relates to a fall arrester for a fall arrest system to prevent a user from falling from a ladder, a platform or the like.
  • the Safety gear runs in a guide rail and closes belaying user is through a safety harness with the fall arrester connected.
  • the catching device has one Carriage that runs in the guide rail, as well as a Pawl which is rotatably mounted in the carriage and in the event of a fall against catch catches in the guide rail bumps, and a fastening device for securing the safety harness on the pawl, the fastener has a damping element that in the event of a crash mitigates the impact.
  • Such a catching device is known from EP-A-0 168 021, DE-A-27 36 037 and DE-A-19 61 757 known. It is also known to provide a damping element in the fastening device, by attaching a U-bracket to a pawl mounting ring depends on its two legs, a damping element sits. The free ends of the stirrup legs are completed by a plate. Above the damping elements a plate is also provided, which on the temple legs is movable. There is a on this plate Bolt attached, which is axially parallel to the stirrup legs and stretching down between them and at its there is a fastening eyelet at the free end a carabiner the harness is attachable.
  • the invention has for its object a safety gear to create with damping element in which the fastening device takes up as little space as possible and no more eyelet connections than necessary are.
  • this object is achieved in that the Damping element on a peg-shaped extension of the pawl sits that above the damping element on the peg-shaped Approach a cross piece is guided and on the damping element abuts, the harness on the crosspiece can be fastened, the cross piece is part of a shackle ring and the two ends of the crosspiece are the steering knuckles, on which the eyes of the shackle bracket sit.
  • the damping element is preferably a tube with a Length of approximately 23 mm, an inner diameter of 12 mm and an outer diameter of approx. 24 mm from a Fibroflex® round rod with a hardness of 90 Shore A (yellow) like him from the company Fibro GmbH, 74 855 Hassmersheim, FRG, under the order no. 253.6.025 is available.
  • the catching device shown in FIGS. 1 and 2 consists of a carriage 1 in a guide rail, not shown to be led.
  • the guide rail has that out DE-A-0 168 021 known C-profile with guide lips, which as Serve guide flanges.
  • the carriage 1 points to both Side guide grooves 2 on the guide lips of the guide rail record, tape.
  • the carriage 1 has a slot-shaped opening 5 on, in which a pawl 6 on a pin 7 rotatable is stored.
  • the nose 8 of the pawl 6 protrudes from that Slide carriage 1 forward and into the interior of the C-profile the guide rail in that the nose 8 against the Catch catches.
  • the pawl 6 is at its upper end mounted by means of the pin 7 and the back 9 of the nose 8 is bevelled downwards from the journal bearing.
  • the pawl 6 is under the action of a compression spring 10, above the pin bearing 7 against the pawl 6th presses so that the nose 8 as far as possible from the carriage 1 stands out. If the carriage 1 is e.g. when climbing a ladder pulled up, it runs Back 9 of the nose 8 from below against the catch and will pushed back due to its bevel, so that the Catch catches are run over. Since the cone-shaped approach 11 points downwards and clearly below the journal bearing 7 lies, the nose 8 dips into the carriage 1 when over the harness and the shackle ring 15 an upward Train is exerted on the pin-shaped extension 11.
  • the pawl 6 protrudes from the slot-shaped opening 5 also to the rear, i.e. towards the user and is there provided with a cone-shaped extension 11.
  • a damping element 12 is arranged, which is held with a lock nut 13. over the damping element 12, i.e. between damping element 12 and the carriage 1 sits on the neck 11 a vortex or Crosspiece 14 which has an eyelet in the middle for receiving the Approach 11 has.
  • a washer between this and the crosspiece 14 19 inserted.
  • the two lateral ends of the Crosspiece 14 are as a knuckle of a shackle ring 15 formed, the two eyelets 16 at the ends of the shackle bracket 17 sit on the steering knuckles.
