Locking device (1) for office chairs and the like comprising of a first locking element (9) operatively associable to a base unit (3) of a chair and a second locking element (10) operatively associable at least to a revolving portion (6) of the chair. The first and second locking elements (10) are selectively associable in an active position to lock the rotation of the revolving portion (6) in respect to a base unit (3) and detachable in a passive position to unlock such rotation. The shifting between the active position and the passive position takes place along a shifting direction (11) substantially perpendicular to the contrasting force developing between the locking elements (9, 10) in active position. The shifting direction (11) is also substantially perpendicular to the components of the contrasting force, tangential and perpendicular to the contact surfaces between the engaging portions (9a, 10a).

L'invention concerne un dispositif de blocage (1) destiné à des chaises de bureau et analogue et comprenant un premier élément de blocage (9) pouvant être couplé fonctionnel à une unité de base (3) d'une chaise ainsi qu'un second élément de blocage (10) pouvant être couplé fonctionnel au moins à une partie rotative (6) de la chaise. Lesdits premier et second éléments de blocage (9, 10) peuvent être sélectivement solidarisés, dans une position active, de façon à empêcher la rotation de la partie rotative (6) par rapport à l'unité de base (3), et peuvent être désolidarisés, dans une position passive, de façon à permettre cette rotation. Le passage de la position active à la position passive se produit dans un sens de changement (11) sensiblement perpendiculaire à la force d'opposition se développant entre les éléments de blocage (9, 10) dans la position active. Le sens de changement (11) est également sensiblement perpendiculaire aux composantes de la force d'opposition, soit une composante tangentielle et une composante perpendiculaire aux surfaces de contact entre les parties entrant en prise (9a, 10a).
