Orbital single-brush machine for treating floors

Abstract

An orbital single-brush machine comprising a frame which rests on the floor and is provided with at least one movement handle; the frame being connected to a motor which is adapted to actuate with combined rotary and orbital motion a work tool that acts on the floor; the frame comprising a first substantially plate-shaped footing which is spaced apart from the floor, and a second substantially plate-shaped footing which supports the motor and is arranged below the first footing and is supported so that it can rotate freely by the first footing about an oscillation axis that is substantially parallel to the floor and substantially perpendicular to the advancement direction of the machine.

         12 . An orbital single-brush machine comprising a frame which rests on the floor and is provided with at least one movement handle, a motor being connected to said frame and being adapted to actuate with a combined rotary and orbital motion a work tool that is adapted to act on the floor, wherein said frame comprises a first substantially plate-shaped footing which is spaced apart from the floor and a second substantially plate-shaped footing which is arranged below said first footing and is supported so that it can rotate freely by said first footing about an oscillation axis that is substantially parallel to the floor and substantially perpendicular to the advancement direction of the machine, said second footing supporting said motor. 
     
     
         13 . The machine according to  claim 12 , wherein said first footing is provided in a rear region, with respect to an advancement direction of the machine, with at least one pair of wheels resting on the floor which are mutually opposite. 
     
     
         14 . The machine according to  claim 12 , wherein said second substantially plate-shaped footing is freely pivoted to said first substantially plate-shaped footing about said oscillation axis by way of a pair of hinges which are mutually opposite with respect to said motor. 
     
     
         15 . The machine according to  claim 12 , wherein said motor is fixed to a face of said second substantially plate-shaped footing that is directed toward said first substantially plate-shaped footing. 
     
     
         16 . The machine according to  claim 12 , wherein said first substantially plate-shaped footing has a passage opening which is passed through by said motor. 
     
     
         17 . The machine according to  claim 12 , wherein said second substantially plate-shaped footing supports, on a side thereof directed toward the floor, means of kinematic connection between said motor and said work tool which are adapted to give said work tool a combined rotary and orbital motion. 
     
     
         18 . The machine according to  claim 12 , wherein said first substantially plate-shaped footing and said motor are accommodated within a single containment housing. 
     
     
         19 . The machine according to  claim 18 , wherein said single containment housing extends to also cover at least partially said second footing. 
     
     
         20 . The machine according to  claim 12 , wherein said first substantially plate-shaped footing supports at least one nozzle for dispensing a floor treatment liquid, which is connected to a supply tank. 
     
     
         21 . The machine according to  claim 12 , wherein said work tool is a brush. 
     
     
         22 . The machine according to  claim 12 , wherein said work tool comprises a polishing pad.
