LINK CHAIN DEVICE

摘要

The inventive link chain device comprises a plurality of link elements (10; 110) which form the link chain (7; 107), and a tension device which comprises at least one tension rope extending through the link elements (10; 110) or at least one tension wire (8, 108) extending through the link elements (10; 110). The link chain (7; 107) can be produced by tensing the tension rope or the tension wire (8, 108) in a fixed state, wherein adjacent link elements (10, 110) are fixed in relation to each other, and by tensing the tension rope or tension wire (8; 108) in a flexible state, wherein adjacent link elements (10; 110) can be moved in relation to each other. The inventive link chain device is characterised in that the tension device comprises a shape memory element (8) or a shape memory spring (115) which is arranged and configured in such a manner that the fixed state can be brought about or cancelled by altering the state of the shape of the shape memory element (8) and/or the shape memory spring (115).
