Abstract

Colonna ammortizzata girevole per sedia da ufficio del tipo a due corpi cilindriformi:- una colonna di base (2);- un cannotto a pistone (1);- uno stelo di comando (11) scorrevole assialmente entro detto cannotto per azionare un pistone a cassetto inferiore (114-115) che permette od impedisce, a seconda della sua posizione, il travaso di un fluido in un comparto superiore "SS +S" fra due camere rispettivamente superiore "SS" ed inferiore "S", ai fini di rendere possibile l'allungamento o l'accorciamento dell'intera colonna in una condizione di equilibrio indifferente, in cui:? detta camera inferiore del comparto superiore "S" è collegata direttamente alla detta camera di fondo del detto comparto inferiore "I",? in dette camere superiore "SS" ed inferiore "S" di detto scomparto superiore "SS +S" ed in detta camera di fondo di detto scomparto inferiore "I" si trova esclusivamente aria compressa "a";? in modo che:- quando si vuole variare l'altezza, si sposta assialmente il detto stelo di comando (11) affinché il detto cassetto (114-115) metta in comunicazione (122-123) la detta camera inferiore "S" con la detta camera superiore "SS" in detto scomparto superiore lasciando trafilare aria per compensazione;- quando ci si siede, a comando di variazione altezza bloccato mediante spostamento del detto stelo di comando in una posizione in cui detto travaso non sia possibile, il detto cannotto a pistone (10-13-131) scende entro la detta colonna di base comprimendo la camera d'aria di fondo (I) e detta camera inferiore "S", e viceversa con il ritorno elastico al mancare dell'effetto di compressione.(FIG. 1).Cushioned revolving column for office chair of the type with two cylindrical bodies: - a base column (2); - a piston sleeve (1); - a control stem (11) sliding axially within said sleeve to operate a piston with lower drawer (114-115) which allows or prevents, according to its position, the transfer of a fluid in an upper compartment "SS + S" between two chambers respectively upper "SS" and lower "S", in order to make Is it possible to lengthen or shorten the entire column in a condition of indifferent equilibrium, in which :? said lower chamber of the upper compartment "S" is connected directly to said bottom chamber of said lower compartment "I" ,? in said upper chambers "SS" and lower chambers "S" of said upper compartment "SS + S" and in said bottom chamber of said lower compartment "I" there is exclusively compressed air "a"; so that: - when it is desired to vary the height, said control stem (11) is moved axially so that said drawer (114-115) connects (122-123) said lower chamber "S" with the said upper chamber "SS" in said upper compartment allowing air to draw through for compensation; - when you sit, when the height variation command is blocked by moving the said control stem to a position where said transfer is not possible, the said quill piston (10-13-131) descends within said base column compressing the bottom air chamber (I) and said lower chamber "S", and vice versa with the elastic return when the compression effect is missing. (FIG . 1).
