  • Patent number: 7160044
    Abstract: A mop assembly including a mop head and handle, and a supply of liquid connected to a valve assembly on the handle. The valve assembly includes a replaceable length of resiliently flexible tubing having a portion extending transversely through the handle and members on opposite sides of the length of tubing that are relatively movable between a closed position pinching together opposite sides of the tubing to stop the flow of liquid through it, and a spaced open position affording flow of liquid through the tube. A storage cart includes a main portion and a tray portion having a receptacle for receiving the mop head mounted on the main portion for relative movement between a vertical closed position at which the main portion covers an open side of the receptacle; and a horizontal open position at which the mop head can be inserted into or removed from the receptacle.

  • Patent number: 6854912
    Abstract: A mop assembly including a mop head and handle, and a supply of liquid connected to a valve assembly on the handle adjacent the mop head. The valve assembly includes a length of resiliently flexible tubing that has a portion extending transversely through the handle and first and second members on opposite sides of the length of tubing that are relatively movable between a closed position at which the first and second members pinch together opposite sides of the length of tubing to stop the flow of liquid through it, and an open position at which the first and second members are spaced apart to afford flow of liquid through it. Should the tubing become plugged, it can easily be replaced by disconnecting one end from a liquid supply length of tubing, withdrawing the tubing from between the first and second members, and then installing a new length of tubing.
