Definitions

  • the present invention relates to a fall protection device for construction sites on flat roofs with Vertical posts, between the vertical posts connected balusters, one each articulated a vertical post attached to the bearing arm Flat roof surface is placed, and a weight unit, the end area facing away from the flat roof front edge of the bearing arm is arranged releasably.
  • a fall protection device of the type mentioned Art is from European patent application 0 288 100 known. This also applies to the immediate area of the bearing arm or under which roof work can be carried out the bearing arm can be swiveled upwards. The supporting function of the railing take over the two in this area adjacent bearing arms with connected vertical posts.
  • the present invention has the technical problem or the task, a fall protection device specify a simple and has a robust structure, easily assembled or can be dismantled and also in the area of flat roofs can be used with parapets and above in addition, a permanently reliable fall protection can be guaranteed.
  • the fall protection device is distinguished is accordingly characterized in that the bearing arm in its the Flat roof front edge facing end area one up pointing first cantilever, the vertical post its downward-facing end area one to the flat roof has indicative second cantilever, the free end region of the first and second cantilever arms via a joint are connected such that when the fall arrest device is installed the bearing arm up to the joint can be swung away once the weight unit has been removed.
  • a particularly simple design and a permanent one embodiment ensuring reliable function is characterized in that in the area of the joint on first cantilever arm and a stop on the second cantilever arm Counter stop or vice versa is present, such that in assembled state of the fall protection device first and second cantilever a predetermined angle, in particular, make a right angle to each other.
  • An economical manufacture of the fall protection device is characterized in that the first cantilever and / or the second cantilever arm by bending the bearing arm or vertical post is formed, whereby also alternatively, a welded connection of the cantilever arms is conceivable is.
  • the joint as a detachable Joint is formed, preferably the individual parts Have a length of less than 2 m (meters), so that a Transport of the components of the fall protection device is easily possible within an elevator.
  • a structurally particularly economical to manufacture and permanently reliable training in Joint area is characterized by the fact that the first Cantilever arm and the second cantilever formed as a hollow profile and the first cantilever arm is one in its upper end region Has through hole within which a bolt or a bolt is mounted and the second cantilever in its end region two spaced apart Has articulated straps that are articulated on the outside Bolts or the bolt screw are connected.
  • a particularly advantageous Embodiment characterized in that for connecting the Handrails of the vertical posts each with a rosette Has recesses and the handrails in their Have a recording head, the one after Open slot at the front to slide onto the rosette and another perpendicular to the open slot Has slot for driving in a wedge.
  • the profile unit can also have a recording head with wedge to attach to the bottom rosette of the vertical post to be able to be connected.
  • the geometry of the fall protection device without any geometry of an attic of a flat roof can be customized, one stands out preferred embodiment characterized in that the first cantilever and the second cantilever arm are adjustable in length.
  • a fall protection device 10 has one Vertical post 12 with an upper rosette 40.1 and one lower rosette 40.2 for horizontal connection extending, not shown in Figures 1 and 2 shown railing bars 14 (see Figure 3).
  • the first cantilever arm 24 forms just below the joint 28 in its front area facing the vertical post 12 a counter stop 32 to stop 30.
  • the fall protection device is in the state shown in FIG 10 on a flat roof surface 18 with Flat roof leading edge 22 mounted.
  • the bearing arm 16 lies on the flat roof surface 18.
  • To prevent railing rod 14 to the outside is on the Flat roof leading edge 22 opposite end region of the Bearing arm 16 a weight unit 20 arranged on a pin 52 is threaded.
  • first cantilever arm 24 points upwards and that Hinge 28 at a height H above the flat roof surface 18 is arranged, it is easily possible to have a flat roof Attic 36 with the fall arrest device 10 pivotrüsten.
  • To move the fall protection device 10 towards the flat roof surface 18 when attacked to reliably prevent a force S is at the bottom Rosette 40.2 of the vertical post 12 one down Pointing profile unit 34 arranged to the Flat roof leading edge 22 creates.
  • FIG. 2 An intermediate pivoting position of the bearing arm 16 is shown in FIG. 2 shown schematically. In this state they take over two adjacent bearing arms 16 the occurring Loads, which can be seen from Figure 3. Also from FIG. 3 shows that the rosettes 40.1 or 40.2 each running horizontally Railings 14 are connected. As in Figure 2 the upper edge of the vertical post 12 is shown a stop for the bearing arm 16 in the folded position.
  • FIG 4 shows schematically a detailed perspective of a constructive embodiment.
  • the vertical post 12 is designed as a round tube.
  • the upper or lower Rosette 40.1 or 40.2 has all around recesses in the form of a grid 42.
  • Each railing rod 14 has a receiving head 44 in its end region, the via a slit on the rosette 40.1 respectively 40.2 can be postponed.
  • Perpendicular to this slot there is a clamping wedge 46 in another slot, the clamping in the recess 42 of the rosettes 40.1 or 40.2 can be taken.
  • This reliable connection technology is in the house of the applicant developed and known for years.
  • a second cantilever arm 26 pointing inward at right angles welded, which is designed as a square tube.
  • in the right end region of the square tube of the second cantilever arm 26 are two on the right and left on the outside pointing link plates 48 with a bolt recess available.
  • Articulated straps 48 are at a right angle downwards pointing first cantilever arm 24 through holes, so that a hinge pin not shown in Figure 4 or a hinge pin inserted into the recesses articulated connection between the first cantilever arm 24 and the second cantilever arm 26.
  • the hinge axis 50 is in Figure 4 shown in dash-dot lines.
  • the first cantilever arm 24 forms an upwardly bent one End region of the bearing arm 16, which on the flat roof surface 18th rests.
  • the bearing arm 16 is a round tube profile educated.
  • the bearing arm is in its rear end region 16 secured by weight units 20 against lifting.
  • the right end face of the second cantilever arm 26 forms the Stop 30 and the corresponding opposite
  • the outer wall of the first cantilever arm 24 forms the counter stop 32, so that in the assembled state there is a right angle between the first and second cantilever arms 24, 26.
  • the Profile unit 34 is designed as a square tube.
