- the two lateral legs 354.1 and 354.2 have subsequently to the centering collar 390, respectively also in the direction of the longitudinal axis of the horizontal support bar 24 and its longitudinal wall parts extending Centering tabs 397.1 and 397.2 on.
- Their outer surfaces 398.1 and 398.2 are spaced apart by the distance the side wall parts or the side legs of the horizontal support bar 24 equals, allowing easy assembly in production is possible.
- connection head 440 which is designed with a joint part Connection head 440 to the pivotable connection of a Diagonal bar 23 shown.
- the connection head 440 has the Connection part 450 and the plant part 480, which with the upper header 444, the lower header 445 and the horizontal slot 460 is formed.
- the plant part 480 is at the transition to the advantageous in terms of the joint part designed Connection part 450 is the same design as the connection head 40 for connecting the pipe 38.
- the terminal part 450 is connected to the vertical wall part 485 and the hinge flap 490 formed.
- the joint flap 490 has in its disk-shaped vertical end portions the parallel outer surfaces 491 and 492 on. At its end facing away from the connection part 450 end 496 the joint 490 with the radius 497 designed. Concentric with the radius 497 is the bore 495 intended. Its longitudinal axis is normal to the outer surfaces 491, 492 formed and serves to receive a with the Diagonal rod 27 connectable cylindrical bearing and Articulated element.
- the distance of the bore 495 of the Vertical wall portion 485 and its outer contour are so designed so that the diagonal bar 23 from a center position to both sides exactly 90 ° to the slot plane is pivotable.
- connection heads 40, 340, 440 with the part-spherical, bevelled and rounded wall parts avoids an undesirable Tilting the stacked in a transport box Connection heads 40, 340, 440. This allows an increased Positional and transport safety by separating the Connection heads 40, 340, 440 and easy removal of the Stacked connection heads 40, 340, 440.
