Mop holder, connecting piece, kit of parts, and use thereof

Abstract

A mop holder, in cases a flat mop holder, having an upper side and an opposite lower side, which faces or can face, in cases, an inner side of a mop cover, comprises, in a region of the upper side, a connecting piece which is adapted and arranged to receive a mop handle and to connect the mop handle to the mop holder. The connecting piece comprises a pivot-tilt joint which is adapted and arranged to permit a movability of the mop holder relative to the mop handle about an axis of rotation and about a tilt axis. The pivot-tilt joint comprises an elastic pretensioning device which is adapted and arranged to urge the mop holder with respect to the tilt axis and with respect to the axis of rotation into a predetermined, in cases central, starting position.
