Definitions

• the present invention concerns the technical sector relative to the production of accessories for washing floors.
• it concerns the technical sector relative to the production of accessories to wring clothes for washing floors, specifically clothes made of a series of strings, used by many producers, among them "Vileda”.
• Background Art The type of cloth mainly used nowadays is the one having the above-mentioned shape, also called “mop”, comprising a series of cloth strings of definite length, of variable thickness, largeness and absorption of liquids, free on one side and contained on the opposite side by a final support of various shapes, connected in its turn to the common shaft having such a diameter and height as to permit to be conveniently handled.
• This specific tool which is well-known and for this reason will be briefly described, is generally equipped with a further device having hollow circular shape (which will be called hereinafter “wringer”) and holes or openings on its surface, as well as lateral wings used for the assembly by fitting or by simple laying on the edges of a commoA bucket; by means of this device, filling just one portion of the open upper space of the bucket, the user can dip the cloth of the mop into the mixture of water and soaps contained inside, then he/she can easily lift the mop and wring it inside the hollow holed portion of the cited device.
• Wringer hollow circular shape
• this operation is carried out by a combined action of pressure and rotation of the mop inside the "wringer", so as to eliminate the water in excess adsorbed by the cloth that, through the holes, falls in the bucket or, in more complex models, in a suitable distinct sector created inside the same bucket in order to separate the clean water from the dirty water.
• these manufacturing variations does not affect at all the dynamic, the advantages and the effectiveness of this invention, as it can be anyway applied on any type, shape, size or model of holed "wringer” device.
• the above-described invention is disclosed by the patent No. DE 19503572.
• the present invention aims at avoiding the above-mentioned and other drawbacks, supplying a manual device, ergonomic and highly effective, requiring limited specific operative force, easy to use, having few risks of reversal, which can be applied as accessory to existing buckets or integrated in future productions, with the characteristics described in the independent claims.
