Profile-rail system

Abstract

A profile-rail system ( 1 ) serves for bridging floor-covering transitions and terminations and/or stair or step edges. The profile-rail system ( 1 ) has at least one cover profile ( 3 ), which has at least one covering wing ( 14 ). This covering wing ( 14 ) engages over a floor-covering end ( 15 ), the cover profile or at least one of the covering wings ( 14 ) being adjustable. The cover profile or at least one of the covering wings ( 14 ) is/are pushed against the floor covering ( 16 ) by at least one spring ( 23 ), the spring ( 23 ) being designed as a separate part and having an unstable spring characteristic (FIG. 1 ).
