System for separating paths, flower beds from grass surfaces, has concrete milled-edge stone and corner stone with interacting slot-spring system

摘要

A system consisting of at least one linearly-extending concrete milled-edge stone (1) and a concrete-edged corner stone forming a right-angled configuration. The concrete milled-edge stone (1) and the corner stone have at their joining point (4) an interacting slot-spring system (5,6).
