Butterfly-type wringer mops each include a mop handle having an elongated direction, a receiver immovably coupled to one longitudinal end of the handle and a mop head pivotally attached to the receiver The mop head includes a central member pivotally mounted to the receiver. First and second paddles are pivotally coupled with opposing lateral sides of the central member. The central member and paddles can receive and support an elongated absorbent element. The mop further includes a wringer having one end pivotally coupled to one of the receiver and the central member so as to pivot between a retracted position and an extended position. The wringer includes a pair of spaced apart arms which deflect the paddles from initial positions generally coplanar with one another and transverse to the elongated direction of the mop handle to rotated positions generally side by side parallel to one another as the wringer moves between retracted and extended positions. The mop head can be pivoted on the receiver at least 45 degrees and preferably at least about 90 degrees or more from an initial position in which the elongated direction of the mop head is at least generally perpendicular to the elongated direction of the mop handle, so as to be parallel or at least more closely parallel with the elongated direction of the mop handle. The mop head can be pivoted in different ways. An upper portion of the central member of the head can be formed into a handle to be directly grasped or formed into an arm coupled by a rigid link to a lever pivotally mounted on the mop handle or provided with gear teeth engaged by teeth on the end of a shaft on or in the mop handle. Also the wringer can be used as a handle. An absorbent element that can be used on the mops has at least one and may have two tapered longitudinal tips, which may be of different material(s) from the main body of the element. |
