  • the two connecting plates 46 rest in the region of the joint 47 on the inside and on the outside of the profile crossbar of the associated metal profile in the manner of clamping claws.
  • Both connecting plates 46 and the associated profile crossbar are penetrated by two bolts 49 which are spaced apart from one another transversely to the longitudinal center plane of the associated metal profile 39.
  • These bolts 49 pass through elongated holes 48 in the connecting plates 46 or in the cross-piece of the profile, which extend essentially around the articulated axis or are approximately at such an angle at an acute angle to one another, the bolts 49 engaging in the elongated holes 48 with a corresponding transverse play .
  • the hinge 47 is fixed in the set position by bolts with nuts or by screws screwed into the profile.
  • the maximum limited swivel angle can be changed by appropriate angular position and / or curvature of the elongated holes.
  • the distance between the two screws enables secure clamping with a large lever arm.
  • the angle connection 45 can also be released.
  • At least the two larger metal profiles 37, 38 can each have a length of approximately 2 m, while the smallest metal profile 39, on the other hand, is expediently shorter.
  • the metal profiles 37, 38, 39 are preferably made of aluminum. But plastic profiles are also conceivable.
  • each tensioning arm 17d, 18d is formed by a V-profile 21d or 22d, which is expediently made by bending a sheet metal accordingly strip is made. Both sheet metal profiles can be of the same design and are each attached to the post body 2d in the manner of an arm which projects freely over its entire length.
  • the upper tension arm 18d is fixed to the lower end surface of the post body 6d or the telescopic outer tube by welding so that it extends to the outer outer surface thereof. Accordingly, the lower tension arm 17d is fixed to the lower end surface of the telescopic inner rod 8d.
  • the upper clamping arm 18d is free of additional stiffening struts, such as are shown in FIG.
  • This lower clamping arm 17d is reinforced with an additional, angular stiffening, which is fastened by welding with a shorter leg on the outer outer surface of the telescopic inner rod 8d and with a longer angle leg on the underside of the clamping arm 17d facing away from the associated clamping surface 23d, and also in the form of a web and is narrower than both the inner rod 8d and the tension arm 17d.
  • the lower end face of the post body 6d is provided with a V-shaped groove adapted to the profile of the tensioning arm 18d, so that the respective profile leg of the tensioning arm 18d connects in cross section at an obtuse angle to the associated outer surface of the post body 6d and projects laterally beyond this outer surface.
  • the associated end of the tensioning arm 18d is provided with a through opening which is adapted to the inner cross sections of the post body 6d and is penetrated by the inner rod 8d.
  • this inner rod 8d is adapted by V-shaped tapering to the inner cross section of the clamping arm 17d, which extends to the outer outer surface of the inner rod 8d or to the associated leg of the stiffening angle 52 and whose profile leg also laterally on both sides via the inner rod 8d protrude.
  • the profile legs of the two clamping arms 17d, 18d are directed towards one another and each form clamping area regions 23d, 24d with an edge of each edge surface.
  • the clamping surface areas 23d, 24d of each clamping arm 17d or 18d are parallel to one another at a distance from one another which is greater than the thickness of the railing post 2d, but two clamping surface areas 23d, 24d each parallel to the longitudinal direction of the railing post 2s Opposite direction. This results in a very precisely defined contact of the tension arms 17d, 18d on the associated surfaces of the building part 19d.
  • a holder 50 is provided on the outer outside of the post body 6d of the railing post 2d, which e.g. is formed by three identical brackets 51 lying one above the other at equal intervals and which are narrower than the associated outer side of the post body 6d.
  • Each bracket 51 is fastened with the end faces of its bracket legs to the aforementioned outer side of the post body 6d by welding, the upper bracket leg of the uppermost bracket 51 expediently directly adjoining the upper end of the post body 6d and the lower bracket leg of the lowest bracket 51 closely adjacent to the lower one End surface of this post body 6d is.
  • FIG. 9 and 10 show a railing post 6b, which consists of a round or square tube, in the lower end of which a flange 50 is welded in the form of a square plate.
  • An elongated, rectangular slot 51 is provided in the plate and on the underside of the A pipe section is welded onto the flange, which forms the fastening device 4b, which, like that according to FIG. 3, is designed as an internal collet 9b.
  • the round tube piece is tapered and slotted towards its lower end, so that two tong arms 25b with a semicircular shell profile are formed, which are separated from one another by the slot 53.
  • a clamping part 8b can be driven into the interior of the forceps arms, which extends through the entire railing post 6b up to its upper end 54 and has an elongated, rectangular cross section corresponding to the opening 51 which guides it.
  • a cross pin 55 is inserted near the lower end so that the rod-shaped clamping part cannot be pulled out upwards because the pin locks on the flange 50.
  • the taper is exaggerated for better illustration.
  • a larger hole 56 is provided in the upper end of the clamping part, into which a tool, for example the pick of a mason hammer, can engage in order to pull out the clamping part.
  • the plug pin 9b of the fastening device 4b can be inserted into a hole 57 drilled, for example, in a concrete slab and fastened by hammering in the clamping part 8b from above, the tong arms 25b spreading apart with transverse movement when the clamping part penetrates into the interior between the tong arms. It has been shown that an expansion up to approximately the cylindrical shape is usually sufficient for fixing. If this is not the case and further anchoring is desired, for example on less solid ground, e.g.
  • the spreading can also extend beyond the cylindrical shape, for example by the pliers arms 25b with beads 60 indicated by dash-dotted lines that widen downwards , are provided and / or by bending the edges of the slot 53 additional gripping surfaces are created that could also be designed like barbs, for example.
