Interlocking system for folding elements , e.g. walls, doors etc.

摘要

The edges of laminates (L1,L2) are linked together so that they fold in and out concertina-like. Open-ended, straight and transverse hollow profiles (1) are provided to the laminates and their open ends (5) are positioned on the outer edges (4) or side surfaces of the laminates. A bar-shaped locking element (2) is inserted into each hollow profile all of which have the same cross section and lie behind one another in a straight line. The ends of the locking elements abut. A cable pull runs through all the locking elements and is segmented and joined by elastic intermediate links inside the locking elements. The cable segments are each fixed to the elastic intermediate link at the ends (5') of the continuous guide near the outer edges (4') of the wall.
