Wringer device for a mopping unit

Abstract

A wringer device for a mopping apparatus includes: a basket-like receptacle rotatably arranged in a support, the receptacle being caused to rotate by a mechanical drive, the drive including a lever movably mounted in the support and being provided with a spindle nut that causes a spindle to rotate when the lever moves; a first gear arranged on the spindle for conjoint rotation; a second gear associated with a rotary shaft of the receptacle; a freewheel arranged between the rotary shaft and the second gear, the freewheel allowing torque to be transmitted to the rotary shaft in only one direction of rotation; and a toothed belt arranged between the first gear and the second gear.

1 . A wringer device for a mopping apparatus, comprising:
 a basket-like receptacle rotatably arranged in a support, the receptacle being configured to be rotated by a mechanical drive, the drive comprising a lever movably mounted in the support and being provided with a spindle nut configured to cause a spindle to rotate when the lever moves;   a first gear arranged on the spindle and configured for conjoint rotation;   a second gear associated with a rotary shaft of the receptacle;   a freewheel arranged between the rotary shaft and the second gear, the freewheel being configured to allow torque to be transmitted to the rotary shaft in only one direction of rotation; and   a toothed belt arranged between the first gear and the second gear.   
     
     
         2 . The wringer device according to  claim 1 , wherein a spring element is associated with the lever, the spring element being configured to automatically move the lever into an initial position when the lever is in an unloaded state. 
     
     
         3 . The wringer device according to  claim 1 , wherein the lever is mounted so as to move in a parallel motion. 
     
     
         4 . The wringer device according to  claim 3 , wherein the lever comprises cut-outs through which guiding elements, which are fixed to the support, project. 
     
     
         5 . The wringer device according to  claim 1 , wherein a free end of the lever is rotatably and tiltably fixed to the support. 
     
     
         6 . The wringer device according to  claim 5 , wherein the lever is rotatably fixed to the support at the free end of the lever which is closer to the rotary shaft. 
     
     
         7 . The wringer device according to  claim 5 , wherein the lever is rotatably fixed to the support at the free end of the lever which is farther from the rotary shaft. 
     
     
         8 . The wringer device according to  claim 1 , wherein a length of the lever is adjustable. 
     
     
         9 . The wringer device according to  claim 1 , wherein a pitch of the spindle is variable. 
     
     
         10 . The wringer device according to  claim 9 , wherein the pitch of the spindle is greater in at least one edge region than in a central region. 
     
     
         11 . The wringer device according to  claim 1 , wherein the spindle nut is pivotally mounted in the lever.
