Patent ID: 8079107

Claim:
An overhead throwing sweeping machine comprising a machine frame ( 1 ) for retaining wheels ( 2 ), whose regions coming to bear on the floor to be cleaned lie in a supporting plane, and the other components of the sweeping machine, a cylindrical sweeping roller ( 4 ) which is rotatable about its longitudinal axis and is retained on jointly adjustable pivoted arms and whose bristles located in a region of a sweeping area during cleaning operation move in a direction of the forward travel of the cleaning machine, a tunnel wall ( 8 ) covering a front and a top region of the sweeping roller ( 4 ) and defining a brush tunnel, and a dirt container ( 6 ) which is arranged behind the sweeping roller ( 4 ) and whose inlet opening faces an end of the brush tunnel and lies with its bottom edge ( 15 ) adjacent to the sweeping roller ( 4 ) and which, in its dirt-receiving position, is held by at least one displaceable supporting element ( 36 ) in a position supported relative to the sweeping roller ( 4 ), wherein, to set the sweeping area, the pivoted arms of the sweeping roller ( 4 ) are pivoted by adjusting a cable control ( 20 ) and in the process a position of the at least one supporting element ( 36 ) is also changed, such that the setting of the sweeping area is combined with the setting of an optimum distance between sweeping roller ( 4 ) and tunnel wall ( 8 ) and with the setting of the optimum distance of the inlet opening of the dirt container ( 6 ) from the sweeping roller ( 4 ), characterized in that one of the pivoted arms of the sweeping roller ( 4 ) is a double-armed lever which, at its arm ( 7 ) remote from the longitudinal axis ( 4 ′) of the sweeping roller ( 4 ), has a bearing surface ( 11 ) for the cable control ( 20 ), one end of which is held in place when the sweeping roller ( 4 ) is lowered into a sweeping position and another end of which is connected to an adjusting mechanism, such that the cable control ( 20 ) holds the pivoted arms in the position for the sweeping position of the sweeping roller ( 4 ) by engagement with the bearing surface ( 11 ), and in that the at least one supporting element ( 36 ) is coupled to the adjusting mechanism, such that the adjustment of the latter both changes an effective length of the cable control ( 20 ) and correspondingly displaces the at least one supporting element ( 36 ).
