Abstract
A wringing device for a wet mop head of a mop head carrier, wherein the wringing device comprises an elastically prestressed, resilient base element and two wringing rollers that are mounted on the base element, the wringing rollers adapted to rotate parallel to one another and arranged to move away from each other in parallel fashion counter to the elastic prestress force in the base element.
Claims35
A device for wringing liquid out of a wet mop head, the wringing device comprising:
- a base element having two ends and an outside surface and comprising a resilient material that is elastically prestressed, and wherein the base element has a U-shaped cross-section formed of two side walls having top, lengthwise edges and end edges, and a channel-shaped bottom that joins the side walls;
- two cylindrical wringing rollers that are mounted in the base element and positioned adjacent to each other such that a roller nip is formed between the wringing rollers the axes of rotation being parallel to each other and the wringing rollers being designed to move away from one another counter to the elastic prestress force in the base element while the axes of rotation remain parallel.
