Abstract

Improvements introduced in a simple telescopic device for support systems, especially of radiogenic sources, comprising a first hollow and fixed tubular element and one or more second hollow and movable tubular elements mounted successively slidingly inside either the first fixed element, either of one of the second mobile elements of superior diameter, characterized by the fact that said second elements, as well as the first, in a metallic material such as steel, are mounted inside either the first element, or inside the second upper diameter element, by means of two or more equidistant sets of four rollers or more, mounted on said second moving elements, so that the axes of rotation of said rollers of each of these sets are located in a transverse plane relative to the axis of the tubular element that carries them, due to the fact that rollers carried by the same second element are aligned according to generatrices thereof, located symmetrically with respect to their axis, and by the fact that the tangent cylinder that surrounds the rollers of the exterior has a diameter slightly greater than the internal diameter of the element in the which the mobile element that carries them is inserted.
