ABSTRACT:
A drawer guiding system comprises a first rail for mounting in a furniture body, a second rail for mounting on a drawer and optionally an intermediate rail between the first and second rails, the rails being connected so as to be reciprocally slidable relative to one another. Pairs of magnetic components associated with respective adjacent rails assist or retard their relative displacement by mutual magnetic attration or repulsion. Each magnetic component is made up of individual magnets with differently aligned polarities, so that some attract corresponding magnets of an associated magnetic component and some repel. As the drawer approaches one end of its travel the overall mutual repulsion between the magnetic components of each pair becomes an attraction or vice-versa.
