Abstract: A table includes a table support; a slide guide secured to the table top; a sliding member received in the slide guide for displacements relative to the table top and parallel to its main plane; a stationary table support; first and second link bars articulated to the table support and the sliding member. The first and second link bars together form a link bar guide. A coupling bar is articulated to a mid region of one of the first and second link bars and to a component affixed to the table top. This construction provides that a pivotal motion of the parallel linkage guide causes a displacement of the sliding member relative to the table top in its main plane and also causes a height-changing displacement of the table top relative to the table support transversely to its main plane, while the table top remains in an unchanged position relative to the main table top plane. Further, a height-arresting device is provided for immobilizing the table top in any height position thereof.
