Definitions

  • the invention relates to a support system with the features of Preamble of claim 1.
  • Field of application of The present invention is, in particular, traffic and signposting devices.
  • the most varied spatial structures are from practice known by connecting, in particular plugging together Rods are formed.
  • the structures are used in particular in the area of the exhibition stand to separate rooms from each other and to be able to attach billboards to it. you are not suitable to absorb larger loads or moments.
  • a support system according to the preamble of claim 1 is known from DE-U-86 07 305. It particularly finds on Trade fair and exhibition stands use. Are at this Connection elements provided, which, in the respective main support part used, a defined angular position of the two with this specify connectable rods. So are the rods where it is components that correspond to the main supporting parts in their shape acts, put on the plug of the connection elements and connected to these in the area of cross holes. The bars are unchangeable in length, so when installing the Support system, the individual components are already assembled and the Bars must have an exact, predetermined length. With This support system cannot have different support system designs are shown and it is the intended one Support system construction cannot be displayed if the individual System components do not exactly meet the specified dimensional tolerances exhibit.
  • NL-A-8 500 510 is a wind dressing system with pull and Pressure rods known. Three engage on the respective connection element Members of which the two diagonal members function as Have tension rods. The two tension rods are variable in length trained and articulated grip on the respective connector on. The pressure rod is rigidly connected to the connecting element and unchangeable in length. The linkage of the tension rods and their variability in length serves the purpose of the wind dressing system to be able to mount after the pressure rod is connected to the assigned tab and via the two tension rods due to the shortening the corresponding Pressure force is introduced into the pressure rod. This system is not suitable as a basis for different system designs to serve, not least because no movable one Sledge is provided.
