Abstract

A guide system for a drawer comprises a mounting rail attached to a piece of furniture, a drawer rail attached to the drawer and supported and guided by the mounting rail for translational movement relative thereto. The rails are provided with vertically superimposed, longitudinally extending magnetic tracks of the same polarity which repel each other and maintain a magnetic air gap therebetween, so that the magnetic repelling forces are load-bearing and maintain the drawer in a suspended condition. Lateral guide means are provided to maintain the vertical alignment of the superimposed magnetic tracks. The magnetic load-bearing tracks may be formed from permanent magnets or electromagnets.
