Abstract

New telescopic leg for tables, of the type in which they have means for fixing the relative position of one tube with the other, is characterized by the fact that the fixing sleeve of the position more or less exit from the inner tube, it is achieved by means of a sleeve of plastics material, substantially flexible, such as polyamide and which is open, longitudinally, so that it constitutes a cylindrical sleeve with perforated base and also with solution of continuity of its generatrix, so that when the locking ring is threaded into the thread of the end of the outer tube, the sleeve is housed in the annular gap between the generatrix of the threaded inner tube and the inner wall of the locking ring, also threaded and the bottom of this locking against the the bottom of the sleeve forces the latter, in turn, through its mouth to press against the mouth of the end of the outer tube, which causes a deformation of the wall of the sleeve. Or, creating protuberances that act as anchoring wedges favored by the longitudinal continuity solution of their walls and when unscrewing the locking nut, the internal sleeve recovers its shape by not tightening the bottom of the nut against the bottom of the sleeve and in by virtue of the elasticity of the material in which it is made and therefore the action of wedge disappearing, the inner tube with limit stops of stroke in its extraction and introduction of the outer tube is free to be able to be fixed in a new position.
