Abstract

Telescopic guide for drawers, characterized in that it is constituted by a set of three metal laminar profiles in mutual insertion, with the ability to slide longitudinally to perform extension and retraction movements, in which the outer profile, fixed in a piece of furniture such as a table or a closet, consists of a full surface with two side bends in incoming curvature on one side, while the central profile has a full surface with a double fold on each side, towards the same face, forming two opposite concave curvatures its back, while the inner profile is composed of a flat surface with a curved ledge coming from the same side, and being fixed in the corresponding drawer, so that between the edges of the outer and central profiles, and between central and interior profiles, there are circular section spaces that contain ball bearings for the mutual sliding of the same profiles in both directions, and opposing faces of said profiles, at certain distances, antagonistic projections, all in such a way that the movement of the drawer in the forward direction, determines that the inner profile moves with the same as length of the outer profile, dragging to the central profile, by the coincidence of its projections, and continuing the latter the route until reaching the end of that, central profile at the end of stroke of the drawer, taking place the retraction of this drawer in an analogous way, under manual push, until the profiles are reintegrated into their mutual insertion position.
