Image Number 2 for United States Patent #4564247.
Roller-bearing-mounted telescopic track for drawers or the like, in which at least one inner track (4) is supported movably in an outer track (2). For this the inner track (4) is preferably constructed in such a way that the two rolling paths (2) directed outward are joined together by a web of an elastic material, preferably rubber. Thereby on one hand a damping of the running noises will be achieved. On the other hand, when there is imprecision of dimensions in the drawer or the cabinet receiving this, stresses between the tracks, which impair the rolling properties, are avoided, since the rolling paths can adapt to these imprecise dimensions within a certain range.
