Floor-cleaning machine

Abstract

A floor-cleaning machine comprising a support trolley ( 2 ), on which support trolley ( 2 ) at least a floor-cleaning group ( 7 ) is installed, which floor-cleaning group ( 7 ) is provided with at least a flexible blade ( 70 ) and is mobile on board the support trolley ( 2 ) between a work position, in which the flexible blade ( 70 ) is in contact with a floor, and a rest position, in which the flexible blade ( 70 ) is distanced from the floor, the floor-cleaning machine comprising magnetic means ( 26 ) which are destined to block the floor-cleaning group ( 7 ) in the rest position.

1 . A floor-cleaning machine comprising a support trolley ( 2 ), on which support trolley ( 2 ) at least an operating group ( 5 ) is installed, which operating group ( 5 ) comprises at least a rotating brush ( 50 ) destined to go into contact with a floor and a motor ( 51 ) for activating the rotating brush ( 50 ), and gripping means ( 31 ) destined to be held by a user to guide the trolley ( 2 ) on the floor, characterised in that the gripping means ( 31 ) are provided by a rigid frame ( 3 ), which rigid frame ( 3 ) is hinged to the support trolley ( 2 ) and on which the operating group ( 5 ) is directly fixed. 
     
     
         2 . The floor-cleaning machine of  claim 1 , characterised in that the rigid frame ( 3 ) is hinged to the support trolley ( 2 ) as a reciprocating lever. 
     
     
         3 . The floor-cleaning machine of  claim 2 , characterised in that the operating group ( 5 ) and the gripping means ( 31 ) are on opposite sides of the rigid frame ( 3 ) with respect to the axis of rotation (A) thereof with respect to the trolley ( 2 ). 
     
     
         4 . The floor-cleaning machine of  claim 1 , characterised in that it comprises blocking means for blocking the rigid frame ( 3 ) in a rest configuration, in which the brush ( 50 ) of the operating group ( 5 ) is distanced from the floor. 
     
     
         5 . The floor-cleaning machine of  claim 4 , characterised in that the blocking means comprise a telescopic arm ( 4 ) hinged to the rigid frame ( 3 ) and to the trolley ( 2 ), which telescopic arm ( 4 ) is provided with disengageable stop means. 
     
     
         6 . The floor-cleaning machine of  claim 1 , characterised in that a suction group ( 6 ) is further fixed on the rigid frame ( 3 ). 
     
     
         7 . The floor-cleaning machine of  claim 6 , characterised in that the suction group ( 6 ) is connected to a collecting reservoir ( 61 ) located on a base ( 20 ) of the trolley ( 2 ). 
     
     
         8 . The floor-cleaning machine of  claim 1 , characterised in that it comprises means ( 63 ,  64 ) for dispensing a cleaning liquid onto the floor. 
     
     
         9 . The floor-cleaning machine of  claim 8 , characterised in that the means for dispensing the cleaning liquid comprise a reservoir ( 63 ) for containing the liquid, which reservoir ( 63 ) is located on the base ( 20 ) of the trolley ( 2 ). 
     
     
         10 . The floor-cleaning machine of  claim 1 , characterised in that it comprises a floor-cleaning group ( 7 ), which is provided with at least a flexible blade ( 70 ) and which is mobile on board the support trolley ( 2 ) between a work position, in which the flexible blade ( 70 ) is in contact with the floor, and a rest position, in which the flexible blade ( 70 ) is distanced from the floor. 
     
     
         11 . The floor-cleaning machine of  claim 10 , characterised in that it comprises magnetic means ( 26 ) which block the floor-cleaning group ( 7 ) in the rest position. 
     
     
         12 . The floor-cleaning machine of  claim 11 , characterised in that the magnetic means comprise at least a magnet ( 26 ) fixed on the trolley ( 2 ). 
     
     
         13 . The floor-cleaning machine of  claim 10 , characterised in that the floor-cleaning group ( 7 ) comprises a pair of flexible blades ( 70 ) separated by a space ( 72 ). 
     
     
         14 . The floor-cleaning machine of  claim 16 , characterised in that the space ( 72 ) is in communication with the suction group ( 6 ) via the collecting reservoir ( 61 ). 
     
     
         15 . The floor-cleaning machine of  claim 7 , characterised in that it comprises a floor-cleaning group ( 7 ), which is provided with at least a flexible blade ( 70 ) and which is mobile on board the support trolley ( 2 ) between a work position, in which the flexible blade ( 70 ) is in contact with the floor, and a rest position, in which the flexible blade ( 70 ) is distanced from the floor. 
     
     
         16 . The floor-cleaning machine of  claim 15 , characterised in that the floor-cleaning group ( 7 ) comprises a pair of flexible blades ( 70 ) separated by a space ( 72 ).
