Abstract

Self-supporting device for extendable rods, of the type which, being located at one of the ends of the set of telescopic rods, achieves the self-clamping pressure of these by the action of an inner spring supported on a part-stop fixed in an area more internal to the device, characterized in that it comprises a solid cylindrical part, fitted on the inside by the bar, provided with a diametrical window between whose longitudinal walls there is located a flat general U-shaped spring, of branches arranged in the longitudinal direction and in the interior of the bar, one of whose branches has a normal central pin and located ex its plane that emerges to the outside of the bar through an existing hole in it; the said cylindrical part, driven by the spring, being able to move from a position in which the innermost end of the window abuts the end of the branch provided with a lug, of the flat spring, to a position of release of the spring and emergency of the cylindrical part with respect to the end of the bar, in which when the emerging pin is pressed, the stop means are released when the corresponding branch of the flat spring is guided in an extension of the window made on this side and in which position the edge interior of the window contacts the lug; there is a cylindrical lid with a concentric neck inside, which is tightly guided in an axial bore, made in the free end of the cylindrical part, the internal diameter of the cover of the lid being slightly superior to the external one of the telescopic bar in which it lodges, counting the cover in its frontal exterior face with a non-slip cajeado.
