  • Patent number: 8156603
    Abstract: A cleaning tool that includes an elongate cleaning element holder and a cleaning element to be attached to the cleaning element holder is provided. The cleaning element holder has a grip to be held by a user and two holding elements extending parallel in a longitudinal direction from the grip. The holding elements are adapted to be inserted into an insert region of the cleaning element to thereby hold the cleaning element. The two holding elements of the cleaning element holder can be rotated in parallel toward each other around a longitudinal axis of the cleaning element holder on a rotation axis disposed between the holding elements. As a result, through the rotation of the two holding elements inserted into the insert region, the sectional shape of the cleaning element can be changed in a direction crossing the longitudinal direction of the cleaning element holder.

  • Patent number: 7966688
    Abstract: A cleaning tool and an effective technique for realizing a higher cleaning effect in the cleaning tool having a cleaning element for wiping a region to be cleaned is provided. A representative cleaning tool for wiping a region to be cleaned includes an elongate cleaning element holder, and a cleaning element having an outer surface which has predetermined dimensions and can extend in a longitudinal direction of the cleaning element holder. The cleaning element is attached to the cleaning element holder. When the cleaning element is attached to the cleaning element holder, the cleaning element is wrapped in a helical form around an outer surface of the cleaning element holder in such a manner that the cleaning element outer surface moves toward the outer surface of the cleaning element holder.
