Abstract
The wringing device in particular for fringed strips for cleaning floors, comprises a frame which oscillatably supports about a main axis, a supporting element for a roller. The roller can rotate with respect to the supporting element about its own axis which is arranged parallel to the main axis. The frame is provided with a wall which faces the roller and is shaped like a portion of a cylindrical surface having an axis which substantially coincides with the main axis. An actuator acts on the supporting element to oscillate it about the main axis, with consequent sliding of the roller along the wall to wring a fringed strip interposed between the roller and the wall.

Wringing device in particular for fringed strips for cleaning floors, comprising a frame which oscillatably supports, about a main axis, a supporting element for a roller which is freely mounted on said supporting element and which is arranged so that its axis is parallel to said main axis, said frame having a wall which faces said roller and being shaped like a portion of a cylindrical surface which has an axis which substantially coincides with said main axis, actuation means being furthermore provided which act on said supporting element for its oscillation about said main axis, with the consequent sliding of said roller along said wall to wring a fringed strip interposed between said roller and said wall, said supporting element comprising a pair of parallel arms which are mutually pivoted, at first ends thereof, to a main shaft having an axis which coincides with said main axis, and which support, at second ends thereof, said roller so that it is rotatable about its own axis with respect to said arms, said actuation means comprising an actuation lever which is fixed to a secondary shaft supported by said frame parallel to said main shaft, a crank being keyed on said secondary shaft, said crank being connected, by means of a connecting rod, to one if said arms, the useful length of said crank being greater than the distance between the pivoting point of said connecting rod on said arm and said main axis in order to multiply the angle of oscillation of said roller about said main axis with respect to the angle of oscillation of said crank induced by said actuation lever.
