Drawer system

Abstract

The invention concerns a drawer system with an automatic self-closing mechanism, with which the kinetic energy is stored when the drawer is opened along the entire opening length in the form of potential energy in energy storage, which potential energy is, after the drawer is released, delivered by a speed regulator in a controlled slow and uniform manner again along the entire closing length to the drawer in the form of kinetic energy. The invention-related closing system has the advantage that the disengagement and release of the drawer, a certain closing movement is guaranteed, without the drawer reaching too high a speed while closing. Thus, the drawer closes softly and very quietly, without fearing damage to the drawer or its contents.
