Abstract
An extensible shaft for tables and the like comprising telescopic tubular elements, coactly incorporating a compensating spring, is characterized essentially in that one of said tubular elements has at least one transverse groove in which one ball plays while the antagonistic surface of the other element, tubular presents a distribution of projections that act as inclined directing stops of the ball, to determine an itinerary of said ball in the axial displacement between tubes, at least one of said projections constituting a selective retention angle of the ball in one of the limits of extensibility.
