Abstract
Device for sliding assembly, characterized in that it is constituted by the coupling of two U-shaped profiles facing each other, one of them being inside the other, the branches of a first profile being preferably straight and perpendicular to the intermediate section and being provided with a series of aligned recesses where partially engaging balls engage, and the branches of the second profile are curved, whereby in the coupling of both profiles they maintain in position said balls, which are interposed between them allowing the relative movement of said profiles.
