Abstract
Lifting column, preferably for height adjustable tables, said lifting column comprising at least two relative to each other telescopically arranged members (2a, 2b, 2c). At least one slider (11) is arranged between the two members (2a, 2b, 2c), said slider being secured to one of the members (2b). The problem is play between the members (2a, 2b, 2c), resulting in an unstable lifting column. For solution of this problem the member (2b) to which the slider (11) is secured, is furnished with a resilient section (17) outlined by a groove (16, 18) against which at least a part of the slider (11) rests. The resilient section (17) can push the slider (11) into firm engagement against the two members (2b, 2c), at which a stable lifting column which is free from play is achieved.
