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

Lifting column preferably for height-adjustable tables

A lifting column preferably, for height adjustable tables, includes a guide () and a drive unit (), the guide () including at least a first member () and a second member (), the members () being arranged mutually telescopically relative to each other. At the end of the first member () from which the second member () can be displaced sliders are arranged on an internal side thereof. At the end of the second member () extending into the first member () sliders are likewise arranged on the outside thereof. In a first plane the sliders have a first, a large, prestressing between the first member () and the second member (), while the sliders in the second plane have a second, a small, prestressing between the first () and second member (). Thus, a good dampening of vibrations of the table is achieved in case of exposure to horizontal forces.

Lifting column, preferably for height adjustable tables

An electrical operating panel, in particular for height-adjustable tables equipped with actuators or lifting columns driven by an electric motor. The panel has a first part () intended for fixed mounting of the panel and a second part () with operating keys () for activating electrical switches. The two parts are hinged together, and the hinge is formed with a rotary shaft () on the no part and a bearing with a cylindrical face () on the other part and formed with interengaging projections () and depressions () such that the second part may assume various angular positions relative to the first part, the force between projections and depressions bearing greater than the necessary operative pressure on the operating keys, but smaller than the force necessary to manually move the second part between the various angular positions. The panel is of simple structure and easy to mount and use. The users may easily set the keyboard part in the desired angular position. Furthermore, the panel yields so that it is not damaged in case of collision with an object.
