Abstract

A track assembly for a drawer includes a guide rail securable to a piece of furniture, a pull-out rail securable to a drawer, and an inner section rail for connecting the guide rail with the pull-out rail. The guide and the pull-out rails are each formed of substantially L-shaped configuration and exhibit extreme edges that are turned inwardly to form three inner curved corner areas for receiving a set of three balls interposed between outer surfaces of the inner section rail and the inner surfaces of the guide rail and the pull-out rail and positioned such as to define corners of a rectangular triangle.
