Surface-cleaning machine with on-board operator

Abstract

A surface-cleaning machine with on-board operator, such as a floor washing-drying machine, a floor washing machine, a sweeper, a high-pressure cleaner, a vacuum cleaner, or similar machines including an operators compartment including a footboard that defines a first fixed reference surface, having adjacent to it at least one pedal to control the surface cleaning machine. The footboard includes at least one resting member defining a second resting surface, with the second resting surface being adjustable with respect to the first fixed reference surface.

1 - 7 . (canceled) 
     
     
         8 . A surface-cleaning machine comprising:
 a compartment adapted to accommodate an operator, the compartment including a footboard that defines a first fixed reference surface, which at least one control pedal of the surface-cleaning machine is adjacent to,   wherein the footboard comprises at least a resting member that defines a second resting surface, the second resting surface being adjustable relative to the first fixed reference surface.   
     
     
         9 . A surface-cleaning machine according to  claim 8 , wherein the resting member is situated in a position close to the control pedal. 
     
     
         10 . A surface-cleaning machine according to  claim 8 , wherein the resting member comprises a bearing head, which is adapted to support a heel of the operator, and which extends downwards with a threaded stem adapted to screw into a nut screw provided in a receptacle of the footboard. 
     
     
         11 . A surface-cleaning machine according to  claim 10 , wherein the bearing head includes a slot adapted to establish an engagement condition for a tool as needed to adjust a depth of insertion of the threaded stem into the nut screw. 
     
     
         12 . A surface-cleaning machine according to  claim 10 , wherein the bearing head includes a plurality of bores adapted to allow for a manual engagement for adjustment of a depth of insertion of the threaded stem into the nut screw. 
     
     
         13 . A surface-cleaning machine according to  claim 11 , wherein the resting member comprises a spring adapted to keep the threaded stem stable in an as-adjusted screwed-in condition thereof in the nut screw. 
     
     
         14 . A surface-cleaning machine according to  claim 12 , wherein the resting member comprises a spring adapted to keep the threaded stem stable in an as-adjusted screwed-in condition thereof in the nut screw. 
     
     
         15 . A surface-cleaning machine according to  claim 13 , wherein a first end portion of the spring urges against a peripheral surface of the bearing head and a second end portion of the spring presses against a peripheral surface of the receptacle, the peripheral surface of the receptacle being located in a position close to an end portion of the threaded stem. 
     
     
         16 . A surface-cleaning machine according to  claim 14 , wherein a first end portion of the spring urges against a peripheral surface of the bearing head and a second end portion of the spring presses against a peripheral surface of the receptacle, the peripheral surface of the receptacle being located in a position close to an end portion of the threaded stem.
