ABSTRACT:
A mop head comprises a central member which is rotatably secured to a swing arm, and two panels which are pivotably connected to the central member. For pivoting the panels on axes which are substantially parallel to the rotational axis of the swing arm there is provided a substantially V-shaped yoke which is connected to the central member and manually pivotable on an axis which is substantially perpendicular to said axes. At its rotational movement, the shanks of the yoke are pressed against a marginal portion of each panel and hereby rotate the panels. The pressure of the yoke against the panels entails a risk for displacement of the panels in the direction of their axes of rotation to such an extent that the engagement between the panels and their bearing means comprised in the central member is released. To eliminate this risk each panel has a cam surface which cooperates with and engages behind an associated blocking surface provided on the central member.
