  • Publication number: 20040019998
    Abstract: A washing apparatus for mop heads and washing pads which has the introduction of cleaning solution into a compartment for the mop as well as an overflow and drain function. The washer provides affordability, eliminates the need for electricity as a power source or lifting the cleaning water so as to drain the unit, and eliminates the possibility of back injuries associated with lifting. The washing apparatus also affords versatility that it can be combined with a mop bucket with a wringer function. Further, it can include accessories such as a spray nozzle or a foam gun.

  • Patent number: 5720073
    Abstract: A mop thread-squeezing apparatus capable of compressing mop thread sufficiently without deteriorating the operability thereof, by applying a great pressing force to the mop thread. A pinion fixed to a driving shaft and a rack supporting one end of a squeezing plate are installed on each of left and right side plates of a squeezing tank. A radius of a pitch circle of the pinion at a point of contact between the pitch circle of the pinion and a pitch line of the rack becomes gradually smaller in a region corresponding to a former half time period of a lever operation and is almost constant in a region corresponding to a latter half time period of the lever operation. In the former half time period of the lever operation, a squeezing plate moves downward rapidly and thus the amount of the downward movement thereof is great, whereas in the latter half time period of the lever operation, the radius of the pitch circle becomes smaller and thus the pressing force of the squeezing plate becomes greater.

    Abstract: An apparatus for wringing the strands of mops has a housing which supports two lateral carriers for a set of horizontal wringing elements which are installed in the housing and are movable toward and away from the inner side of the front wall of the housing. The wringing elements are pivotable within limits about horizontal axes and have limited freedom of upward and downward movement relative to the lateral walls of the housing so that they can conform the orientation of their profiled front sides to the outlines of adjacent portions of a pile of strands which are introduced into the housing between the front wall and the wringing elements while the carriers maintain such elements in retracted positions. The carriers are formed with horizontal toothed racks mating with gear segments which are rotatably mounted in the housing and can be rotated by a pivotable lever so as to move the carriers and the wringing elements toward or away from the front wall.
