Definitions

  • the invention relates to a table, in particular for VDU workstations, with a height-adjustable table top with at least one vertical guide rail, further with a table frame with at least one table column for the telescopic guide rail, and with at least one between the table frame or table column and the Height-adjustable table elements arranged spring strut with inside spring, the adjustable spring strut with its one spring end on the table frame or the table column is articulated and with its other Spring end adjustable against the preload of the Spring varying, with the height-adjustable spring elements connected, strut base is supported, and wherein the strut base by means of a connected adjusting device in different loads on the table top adjusted positions can be locked.
  • a table of the type described above is made known by DE 38 17 102 C2. Of course can with such a table instead of one Table top also realized a variety of table tops his. Also structures on the table top, such. B. shelves, cabinet elements, etc. conceivable. As a general rule form table top and guide bar (or guide bars) the height adjustable table elements while table frame and table column remain stationary.
  • a height adjustment is realized in such a way that the table top in suspension by means of the adjustment spring strut is held.
  • the adjusting device serves for this purpose, which the strut base to different loads adapts to the table top.
  • This adjustment takes place in the known Teaching in such a way that the adjusting device for the Suspension strut base or the supported spring end of the adjustment spring strut designed as a spindle drive with handwheel or crank is. All in all, it becomes a floating fitting realized for a height adjustable table whose Table top - due to the state of limbo - of a relevant operator with minimal effort can be adjusted in height. After reaching the desired one The position of the table top is usually via a (manually operated) parking brake fixed.
