Abstract

Domaine de l'invention : industries électromécaniques. Dispositif de freinage et de blocage d'éléments tubulaires télescopiques entraînables en coulissement les uns dans les autres par des moyens électriques, réalisés en un matériau magnétique, comportant, pour chaque tube mobile, au moins deux couronnes de trois galets chacune préchargées prenant appui sur ledit tube et au moins une ventouse magnétique, fixée au tube à l'intérieur duquel il coulisse, par l'intermédiaire de lames élastiques, chaque ventouse étant constituée par un aimant permanent entouré d'un bobinage électrique tel que lorsqu'il est parcouru par le courant, il annule le champ magnétique dudit aimant, ce champ étant rétabli lorsque le courant est coupé, l'aimant prenant alors appui sur le tube. Application : blocage rigide d'un microscope placé sur une suspension plafonnière au-dessus d'une table d'opération.
