Definitions

  • the invention relates to a device for securing people against falling from a building or the like.
  • Such a device is disclosed in DE-A-3 523 780
  • the invention has for its object to provide a safety device that protects persons entrusted with the work mentioned against falling and that can be attached safely with a few simple steps.
  • This traverse can be placed in a door opening located opposite the endangered workplace so that it rests on the floor and is supported with its two ends on the side of a supporting masonry facing away from the workplace.
  • the adjustable holding leg is adjusted so that the distance measured on the outer sides of the two holding legs corresponds to the clear width of the door opening, so that the traverse lies securely in the door opening.
  • a holding belt can then be attached to the crossmember, the other end of which is connected to a safety harness which the working person has put on. If this then makes a careless movement during work or becomes dizzy, it only falls according to the selected belt length without falling, since the belt is held firmly on the crossbar.
  • the adjustable holding leg is attached to a sleeve which can be displaced on the crossmember.
  • the sleeve is slotted parallel to the longitudinal axis of the crossmember and has two parallel clamping flanges with a clamping screw in the area of the slot.
  • This further embodiment of the invention allows a very simple adjustment of the holding leg attached to the sleeve within the door opening.
  • each of the two clamping flanges has a threaded hole for the engagement of the clamping screw and a through hole for the clamping screw.
  • the adjustable holding leg carries a clamping plate pointing towards the adjacent free end of the crossbeam, which runs parallel to the holding leg.
  • the clamping plate can be adjusted parallel to the longitudinal axis of the crossbar using an adjusting screw.
  • the adjustable holding leg can first be set to the approximate dimension of the clear door width, whereupon the final clamping of the device is carried out by means of the adjustable clamping plate.
  • the crossbeam In its central area, the crossbeam has a fastening eye that protrudes from the crossbeam in the direction of the two holding legs.
  • the tether for the person to be secured can be attached to this fastening eyelet, for example by means of a snap hook. If the door openings are not too wide, it is even possible to secure two people at the same time using a crossbar.
  • Figure 1 shows the top view of a securing device 10 according to the invention.
  • This essentially consists of a traverse 12 with a total length of approximately 140 cm.
  • the traverse 12 is made from a square tubular steel profile with a width of approximately 5 cm and is closed at the two open ends 14 by protective caps 16 made of plastic.
  • a casing 18 made of plastic or the like is placed on the crossmember, which has the task of protecting the wall in the area of the door opening against damage.
  • a holding leg 20 protrudes from one side of the cross member 12 at the left end in FIG. 1, which also consists of a square profile and is welded to the cross member 12. To protect the door opening, the holding leg 20 is also encased in plastic, the free end of the holding leg 20 being closed off by a protective cap 16.
  • a further, also covered holding leg 22 is provided, which, however, is not fixedly connected to the crossmember 12, but to a square sleeve 24 which can be displaced on the crossmember 12 in the direction of its longitudinal axis.
  • the two holding legs 20 and 22 protrude parallel to one another at right angles from the cross member 12.
  • the sleeve 24 is slotted parallel to the longitudinal axis of the cross member 12.
  • the sleeve 24 has two mutually parallel clamping flanges 28.
  • a threaded bore 30 and a push-through bore 32 are machined into each of the two clamping flanges 28, the bores 30, 32 arranged one above the other being aligned with one another according to FIG.
  • the threaded bore 30 is used to screw in a clamping screw 34, the head 36 of which is supported on the top of the respective upper clamping flange 28.
  • the through bore 32 has a larger diameter than the threaded bore 30.
  • the holding leg 22 which is adjustable up to an end stop 68, carries a clamping plate 38 which runs parallel to the holding leg 22 and points to the adjacent free end 14 of the cross member 12.
  • a clamping plate 38 which runs parallel to the holding leg 22 and points to the adjacent free end 14 of the cross member 12.
  • two bolts 40 are fastened, which protrude through two bores 42 into the holding leg 22 made from a square tube.
  • each bolt 40 carries a head 44.
  • a helical compression spring 46 is placed on each bolt 40, one end of which is supported on the head 44 and the other end of which is supported on the inner wall of the holding leg 22.
  • the clamping plate 38 In the central area between the two bolts 40, the clamping plate 38 is supported on an adjusting screw 48 which is screwed into a threaded bushing 50, which in turn is fastened to the opposite side wall of the holding leg 22.
  • the outwardly projecting end of the adjusting screw 48 carries an adjusting button 52.
  • the crossmember 12 carries a fastening eyelet 54 in its central region which projects from the crossmember 12 in the direction of the two holding legs 20, 22.
  • Figures 4 and 5 show how the device 10 according to the invention is used.
  • the device 10 is placed in a door opening 56, the clear width of which should not exceed 110 cm for securing one person and 90 cm for securing two people at the same time.
  • the fixed holding leg 20 rests on one side of the door opening 56, while the opposite holding leg 22 is adjusted by loosening the clamping screw 34 and moving the sleeve 24 until the clamping plate 38 on the opposite inner side of the door opening 56 abuts.
  • the clamping plate 38 is pressed against the opposite wall or door surface by turning the adjusting button 52, so that the device 10 is then securely in the door opening 56 is set.
  • FIG. 7 shows the device 10 in use, a person 60 to be secured who has put on a safety harness 62 being secured by means of a belt 64 which is suspended in the fastening eye 54 of the cross member 12.
  • the crossbeam 12 lies in the door opening 56 in such a way that it rests on the wall side which faces away from the window opening 66 on which the person 60 is working.
  • FIG. 8 there is also the possibility of securing two people 60 simultaneously with the device 10 according to the invention.
  • FIG. 9 shows the window opening 66 from the outside of the building, the person 60 to be secured being secured against falling from height a by means of the device 10.
