PCT No. PCT/CH91/00039 Sec. 371 Date Sep. 23, 1991 Sec. 102(e) Date Sep. 23, 1991 PCT Filed Feb. 13, 1991 PCT Pub. No. WO91/12383 PCT Pub. Date Aug. 22, 1991.A connection element for a three-dimensional framework includes a bolt (6, 7, 8, 9) which by means of a sleeve insert (3) can be fastened rotatably to one end of a rod (11), as well as a sleeve (12) into the axial through-bore of which the bolt is partly inserted, to transmit, sliding axially, a rotary movement of the sleeve (12) to the bolt. The through-bore is only in the front part of the sleeve (12) so that it can transmit a rotary movement of the sleeve (12) to the bolt. At the rear part of the sleeve (12) the through-bore has a circumference which is larger than the circumference of the form-locking front part of the through-bore. The bolt is urged out of the sleeve (12) by a spring (13). The front end part (9) of the connection element can be fastened to a junction part (10) of the three-dimensional framework. |
