  • the insertion of the clamping bolt is facilitated by the fact that the locking bolts) are inserted into transverse bores of the clamping bolt and are fixed therein and that the receptacles in the connectors are provided with diametrically opposed longitudinal grooves for inserting the locking bolts of the clamping bolt.
  • the tensioning bolt only needs to be turned with the lever, whereby the locking bolts take over the tensioning on the connectors.
  • the support arm is held on the coupling element by means of a retaining washer and an O-ring from the end plate or the subsequent crossbar.
  • the crossbeam 10 is supported by table legs 13 as part of a work or office table.
  • two pairs of pivotable support arms are attached in a manner not shown, which carry the height of the worktop 17 and / or the inclination changeable.
  • the crossbar 10 is substantially U-shaped and is covered by a cover as a cable duct.
  • the two side legs of the crossbar 10 are designed as hollow profiles 11 and 12, so that in their end faces Connector 14 with a corresponding cross section can be inserted and fixed therein.
  • the connectors 14 are welded to the crossbar 10 and have a receptacle 19 into which a clamping bolt 40 can be inserted.
  • the clamping bolt 40 is rotatably mounted in a coupling element 20 and can be pivoted with a lever 41 which is inserted through a slot 39 in the coupling element 20. With the locking ring 44, the axial position of the clamping bolt 40 between the connector 14 and the coupling element 20 is fixed.
  • the receptacle 19 in the connector 14 has diametrically arranged longitudinal grooves 15 and 16 so that the clamping bolt 40 can be inserted with the locking bolt 42.
  • the clamping bolt 40 By turning the clamping bolt 40 not only the coupling element 20 on the crossbar 10 but also the end plate 18 and the two support arms 25 and 26 are clamped.
  • the clamping bolt 40 has a clamping head 48 which is supported in a stepped bore 37 of the end plate 18.
  • the end plate 18 presses over the O-ring 46 and the retaining washer 47 on the support arm 25, as shown in FIG. 3.
  • the support arm 25 has, on the side facing the coupling element 20, an arc-shaped guide web 27 which is guided in a form-fitting manner in the arc-shaped guide groove 23 of the coupling element 20.
  • the other end face of the coupling element 20 carries a corresponding circular arc-shaped guide groove 21, so that the coupling element 20 can be attached to both ends of the hollow profiles 11 and 12.
