摘要

A tensioner for tensile means (30) by means of which a tensile means (28) can be tensioned, which has at least a first and a second end, preferably only two ends, comprising a) a first fixing means (32) having a first fixing part (42) in which the first end of the pulling means (28), b) a second fixing means (34) having a second fixing part (64) can be fixed wherein the second end of the pulling means (28), and c) a coupling means that couples the first (32) and the second fixing means 10 (34) to each other so that the first (32) can be fixed and the second fixing means (34) can each move with respect to the other and its mobility is at least restricted on one side, wherein the coupling means comprises a receiving means (36) in which the second is arranged fixing means (34) at least partially, and a retention means (40) for a connection with a element arranged with movement capacity, especially a lifting table (14), where d) the first (32) and the second fixing means (34) can be prestressed with respect to each other through at least two elements helical spring (38), wherein the at least two helical spring elements (38) are arranged with a first axial end to the outer side of the receiving means (36) and with a second axial end in a second fixing part (64) of the second fixing means (34) and the second fixing means (34) comprises a fixing part (56) arranged in the coupling means, and e) the first fixing means (32) is stationary with respect to the coupling means .
