Abstract

L'invention concerne un socle de support (10) pour une table destinée à porter une unité d'affichage d'ordinateur, un moniteur ou équivalent et à régler la position en hauteur de l'unité d'affichage ou du moniteur. Le socle de support (10) comprend un cadre (12) et une partie de coulisse (16) ainsi qu'au moins un guide (11a1, 11a2) pour la partie de coulisse (16). Une vis (15) est prévue laquelle peut être tournée en liaison avec le cadre (11) et laquelle peut venir en contact opérationnel par ses filets (n1) avec des filets correspondants (n2) disposés dans la partie de coulisse (16). Dans l'agencement du dispositif, une table de support (19) pour l'unité d'affichage ou le moniteur ou équivalent est relié(e) à la partie de coulisse (16) par une partie de bras (18). Par la rotation de la vis (15), la partie de coulisse (16) permet une élévation et un abaissement le long des guides (11a1, 11a2) et la table de support (19) reliée à la partie de coulisse (16) peut être réglée dans sa position en hauteur.
