<p>A mop-wringing device has a main frame (2) with a fixed lower support plate (4) and a displaceable upper pressure plate (14). A toggle link mechanism (32-38) pivots the pressure plate downwards about a rear edge pivot (24, 26) connection to squeeze water from a mop head placed between the two plates. The mechanism comprises a torque bar (34) mounted below the support plate and C-form lever arms (36) secured at one end to the bar and connected at the other end to the pressure plate through toggle links (38). The arrangement allows a wide opening of the plates and a high . wringing pressure on the mop head. The pivot connection of the pressure plate comprises upwardly elongate slots (26) for end pivot pins (24), whereby the pressure plate can tilt to a limited degree to adapt to the thickness of the mop head.</p> |
