US Patent 7469441 Floor mop

A floor mop has two mop supporting wings, which carry an absorbent mop layer and are hinge-connected to a common supporting centerpiece. A mop handle is hinge-mounted to the supporting centerpiece via a Cardan joint. A squeezing slider, which is displaceable along the mop handle and is guided non-rotatably, has two rigid squeezing arms whose ends can each be brought into engagement with a guide surface on the upper side of the respectively assigned mop supporting wings via rollers. Each mop supporting wing forms a rectangular trapezium or triangle. The edges running at right angles to the hinge edge of each mop supporting wing form a common straight continuous front edge.
