Title (EN) PILLAR DEVICE
(FR) DISPOSITIF DE COLONNE
Abstract:
(EN) A pillar or stand device comprises an outer stationary pillar part (2) and an inner movable pillar part (3), which is displaceable relative to the outer pillar part with the aid of a pneumatic cylinder (7). In the intermediate spaces (10) between the pillar parts, brake plates (14) are arranged which can be pressed against opposing wall elements (12) on the inner pillar part by elastic bladders (13) or hoses arranged in the intermediate spaces when air is supplied to them, thus locking the pillar parts to each other.
(FR) Un dispositif de colonne ou de montant comprend une partie de colonne fixe extérieure (2) ainsi qu'une partie de colonne mobile intérieure (3), laquelle peut se déplacer par rapport à ladite partie de colonne extérieure à l'aide d'un cylindre pneumatique (7). Dans les espaces intermédiaires (10) situés entre les parties de colonnes sont agencées des plaques de freins (14), lesquelles peuvent être poussées contre des éléments de parois opposés (12) se trouvant sur la partie de colonne intérieure par des vessies élastiques (13) ou des tubes agencés dans les espaces intermédiaires lorsque de l'air leur est acheminé, bloquant ainsi mutuellement les parties de colonne.
