Abstract:
1. A floor care disk for a floor care machine that is adapted for rotating said floor care disk contacting on a floor surface so as to treat the floor surface, wherein said floor care disk comprises a drive plate, which comprises a stiff disk element and plural tongue-shaped tabs that are connected by respective connections to a radially outer portion of said disk element and that respectively extend from said connections radially inwardly toward a radially inner portion of said disk element, wherein said tongue-shaped tabs are flexible or said connections are flexible or both said tongue-shaped tabs and said connections are flexible so that said tongue-shaped tabs are deflectable away from a radial plane of said disk element toward the floor surface during the rotating of said floor care disk, wherein said floor care disk further comprises at least one floor care pad that is mounted on said drive plate so as to be adapted to come into contact with the floor surface, and wherein a respective one of said tongue-shaped tabs and a portion of said pad mounted on said respective tongue-shaped tab together have a center of mass located offset toward the floor surface from a radial plane passing through said connection of said respective tongue-shaped tab, so that a centrifugal force effective on said center of mass during the rotating of said floor care disk will exert a bending moment on said respective tongue-shaped tab toward the floor surface.
