Definitions

  • the invention relates to a band energy absorber to reduce the fall forces in the event of a person falling from a ladder, a climbing path, a platform or the like.
  • the shock absorber has a belt webbing which is connected by interweaving in an area starting from its ends and which has means at the first end of the shock absorber, e.g. a snap hook, for connection to a harness and means at the second end of the fall damper, e.g. Has eyelets, for attachment to a lifting point or a connecting means.
  • the interwoven area is torn open, reducing the fall arrest forces.
  • Such a band energy absorber is known from DE-U-295 02 632.
  • the anchor point When climbing a lattice mast, the anchor point must be constantly re-selected according to the height gain. Every time the anchor point changes, i.e. if the second end of the fall arrester is struck at a higher point, the person is temporarily unsecured.
  • the invention has for its object to enable a complete backup of a person on a climb, in which the anchor point must be progressively reset.
  • this object is achieved in that the belt is sewn into a ring through the interweaving, the regions starting from the ends overlapping on part of the ring circumference and being connected within this overlap by the interweaving, that the means for connecting to a harness is located within the portion of the ring which is between the ends of the overlap area and in which there is no overlap itself, and - that means are provided at each end of the belt for attachment to an anchor point or a connecting means is.
  • the regions of the belt extending from the ends are preferably connected to one another by interweaving on more than half the circumference of the ring.
  • the overlap region lying between the two ends preferably extends over approximately 2/3 of the circumference of the ring.
  • the belt strap preferably consists of two pieces which are connected by a seam at the point at which the means for connecting to a safety belt is located.
  • the two pieces preferably overlap in the area of the means for connecting to a safety harness and are sewn together on both sides of this means.
  • the belt sewn to the ring is folded and packaged in a tubular sleeve that at one end of the
  • Hose cover the means for connecting to a safety harness and at the other end of the hose cover, the two means for fastening to an attachment point or a connection means.
  • the method of weaving a webbing into one another, which tears apart in the event of a fall with a defined force, is known and is therefore not described in more detail here.
  • FIG. 3 shows the folded-up energy absorber from FIG. 1,
  • Fig. 4 shows a second embodiment of the band shock absorber before folding and packing
  • the belt fall damper has a belt strap 10 with two ends 12, 13.
  • the areas 14, 15 of the webbing 10 starting from the ends 12, 13 are superimposed in such a way that a ring 16 is obtained.
  • the regions 14, 15 overlap approximately on 2/3 of the circumference of the ring 16.
  • the interweaving 19 is indicated in the drawing by a zigzag line.
  • the ring 16 as shown in Figs. 2 and 3, is folded into an elongated straight element.
  • the ring 16 is first drawn straight, so that the eyelet 20 is at one end.
  • the right section 33 is folded onto the middle section 32 (arrow I) so that the eyelet 21 is on the outside and the left section 31 is then placed on the middle section (arrow II).
  • the right section 33 then lies between the middle section 32 and the left section 33.
  • the snap hooks 24 lie at one end and the two eyelets 20, 21 are located at the other end a tubular sleeve 36 pushed (Fig. 3) or held together by tapes.
  • the belt shock absorber is now finished.
  • the snap hook 24 is attached to the front or rear safety eye of a standard safety harness of the person to be secured.
  • carabiner hooks 26, 27 are attached to the eyelets 20, 21, at the free ends of which there are also carabiner hooks 28, 29 with which the user can alternately strike. If the user climbs on a lattice mast, he secures himself by alternately striking the two connecting means 26, 27 by means of the snap hooks 28, 29, so that he is secured against falling at any time.
  • the impact impact acts on the interweaving 19 of the belt strap 10 and tears it open from the end at which the eyelet 20, 21 in question, with which the connecting means 26, 27 is connected, which is just struck at this moment.
  • the band energy absorber is pulled out of the hose cover 36 and, depending on the strength of the impact force, the interweaving 19 is torn apart a larger or smaller piece. By tearing apart the weave 19, fall energy is absorbed and the maximum force acting on the user is reduced.
  • a particular advantage of the band fall damper according to the invention is that it also sufficiently damps a case if it is used incorrectly by the user not attaching the safety eye of the safety harness to the snap hook 24, which is located within the simple area of the ring 16, but hooks onto one of the two snap hooks 28, 29 of the connecting means 26, 27 and only uses the other snap hooks 29 and 28 for securing. If the user falls into the fall damper in such a secure manner, the interweaving 19 is also torn open and the case is slowed down. 4 differs from that of FIG. 1 in that the webbing 10 consists of two pieces which are sewn together in the region of the snap hook 24. The two pieces overlap at this point and are connected to the left and right of the snap hook 24 with a seam 40. These two seams 40 are also sewn together to form a loop 42, so that the snap hook 24 is fixed to the webbing 10.
  • the webbing 10 is also not twisted in this embodiment and the one eyelet 20 is therefore inside the ring 16 and the other eyelet 21 outside the ring 16. Each of the eyelets 20, 21 is followed by a short piece of the webbing 10 without interweaving .
  • the eyelet 20 located within the ring 16 is placed outwards over the webbing 10 and both eyelets 20, 21 are directed so that they point away from the snap hook 24 (FIG. 5).
  • the half of the ring 16 facing away from the snap hook 24 is then displaced in the direction of the arrow III, so that it is curved in the same direction as half of the ring 16 with the snap hook 24.
  • the eyelet 20 depending on the inside of the ring 16 becomes now placed parallel to the other eyelet 21 on the outer side facing away from the folded ring 16 (FIG. 6).
  • the webbing 10 folded in this way is compressed laterally and pushed into the tubular sleeve 36.
  • the snap hook 24 looks out again at one end of the tubular casing 36 and the two eyelets 20, 21 at the other end.
  • the damping characteristic is largely independent of which of the two eyelets 20, 21 was just used for striking. Even if the shock absorber is used incorrectly, if the user with its safety harness attached to one of the eyelets 20, 21, the damping characteristics are very good.

Abstract

L'invention concerne un amortisseur de chute à sangle servant à réduire les forces d'amortissement d'une chute. L'amortisseur de chute selon l'invention comporte une sangle (10) jointe par entrelacement dans une zone (14, 15) partant de ses extrémités (12, 13) et présente des éléments (24) de raccordement à une ceinture d'arrêt et, à chaque extrémité, des éléments (20, 21) de fixation à un point d'arrêt ou à un élément de raccordement, de sorte que l'entrelacement se défait en cas de chute. L'amortisseur de chute selon l'invention est caractérisé en ce que la sangle (10) est formée en anneau (16) grâce à l'entrelacement et en ce que les zones (14, 15) partant des extrémités (12, 13) se chevauchent sur une partie de la circonférence de l'anneau et sont jointes à l'intérieur de ce chevauchement (18) par l'entrelacement.
