Abstract

Amortized swivel column for office chair of the type with two cylindrical bodies: a base column (2); a piston tube (1); a command rod (11) axially slideable within said tube to start a piston with inferior valve (114-115) that allows or prevents, depending on its position, the pouring of a fluid into an upper compartment (SS+S) between two chambers respectively upper (SS) and lower (S), to make possible the lengthening or shortening of the entire column in a condition of indifferent equilibrium, in which: said lower chamber of upper compartment (S) is connected directly to the bottom chamber of said lower compartment (I); in said upper (SS) and lower(S) chambers of said upper compartment (SS+S) and in said bottom chamber of said lower compartment (I) only compressed air (a) is found; in such a way that: when one wishes to very the height, one moves the said command rod (11) axially until said valve (114-115) puts said lower chamber (S) into communication (122-123) with said upper chamber (SS) in said upper compartment, allowing air to be drawn for compensation; when one sits down, with the height variation command blocked by means of moving the said command rod in a position in which said pouring is not possible, said piston tube (10-13-131) descends between the said base column pressing the base air chamber (1) and said lower chamber (S), and vice versa with an elastic return if there is no compression.
