  • Publication number: 20080178405
    Abstract: In an embodiment, a mop includes a mop head and a shaft attached to the mop head. A handle is attached to the shaft by a pivot. An actuator member is coupled to the handle between a grip end and the pivot. Translation of the handle causes the actuator member to translate. In an embodiment, the pivot is offset from the shaft and arranged so that the shaft is located between the position where the handle is attached to the actuator member and the position where the handle is attached to the pivot. A stop may be provided to limit the translation of the handle. The actuator member is coupled a mop fiber base that supports mop fibers. The surface of the mop fibers may have a plurality of raised portions.

  • Patent number: 7225495
    Abstract: A separate scrubber is securely attached to a mop that has a sponge mop element. The scrubber is attached to the mounting head with mounting stems. The mounting stems take the form of walls that are spaced at a distance apart. One or more of the walls has an outwardly facing ridge that extends from the wall by no more than half the distance between the walls. Each set of walls extends through an aperture on a mounting head, and the scrubber is held in place by the engagement of the ridges with a mounting face on the mounting head. The walls extend perpendicularly to the length of the body of the scrubber.

  • Publication number: 20040016072
    Abstract: A mop has an angled handle and a working end with a pair of opposed rollers. An actuator on the mop can be moved between a replacement position, a wringing position, and an intermediate use position. When in the replacement position, a mop head can be removably attached to the working end of the handle by sliding the mop head sideways so an arm on a connector passes between a shoulder and a bridge on the mop head. The connector has a loop at its upper end, and is connected to a slotted mounting stem on an actuator. The mop head is also provided with a threaded aperture and slots, allowing it to be used in other mops.

  • Patent number: RE38380
    Abstract: A wringer mop has a conventional handle with mop fibers extending from a lower point on the handle to a collar that can be lifted to a raised axial position and twisted to wring the mop. The mop also has a pawl on a ring fixed to the handle. When the mop is wrung, the pawl automatically engages a set of raised internal ribs inside the collar to prevent the mop from unwinding. The mop can be returned to normal use by simply pushing the collar down, without the need to fuss with button or levers to disengage the pawl from the ribs.
