Definitions

  • the manually-operated sweeper is capable of removing and aspirating dust, debris and other similar dirt even from corner regions which are generally difficult to reach, such as for example the region where a sidewalk and the road surface meet.
  • These known sweepers are generally constituted by a wheeled chassis provided with a steering handlebar, a dirt collection container being associated with said chassis.
  • the rear wheels of the chassis are adapted, by virtue of their rotation, to actuate by means of a first transmission a first brush, which has a horizontal axis which is parallel to the axis of the rear wheels and is adapted to act on the surface below the chassis.
  • the rear wheels by means of a second transmission, actuate a second brush, which has a vertical axis and is supported by an arm which lies in front of the chassis.
  • the sweeper further has, proximate to the first brush, a fan for aspirating the fine dust, lifted by the action of the brushes, toward a filter located inside a protective housing.
  • Such suction fan for fine dust is actuated by a motor drive (motor, gearmotor and the like) which is electric and therefore requires a power supply battery and a battery charger in order to periodically restore its full functionality.
  • a motor drive motor, gearmotor and the like
  • the electric motor and the battery in addition to being, together with the battery charger, important factors in the production costs of the sweeper, are two components which increase the weight of the sweeper.
  • the aim of the present invention is to provide a manually-operated sweeper which is capable of operating in a fully independent manner, without using electric power.
  • an object of the present invention is to provide a manually-operated sweeper in which the fan for aspirating fine dust is not actuated by an electric motor drive.
  • Another object of the present invention is to provide a sweeper whose functionality and efficiency is not lower than that of known types of sweeper.
  • Another object of the present invention is to provide a sweeper whose dirt loading capacity is not lower than that of known types of sweeper.
  • Another object of the present invention is to provide a sweeper which can be operated easily even by an operator lacking particular prior training.
  • a further object of the present invention is to provide a manually-operated sweeper which can be manufactured cheaply with known systems and technologies.
  • a manually-operated sweeper of the type constituted by a wheeled chassis with a steering handlebar, a dirt collection container being associated with said chassis, the rear wheels of said chassis being adapted, by virtue of their rotation, to actuate by means of a first transmission a first brush, which has a horizontal axis which is parallel to the axis of the rear wheels and is adapted to act on the surface that lies below said chassis, and, by means of a second transmission, a second brush, which is supported by an arm which protrudes in front of the chassis, said second brush rotating with a vertical axis, said sweeper also having, proximate to said first brush, a fan for aspirating fine dust raised by the action of said first and second brushes toward a filter located inside a protective housing at an opening leading externally for the escape of the filtered air, said sweeper being characterized in that said fan is turned by way of transmission means actuated by the motion of at least one
  • FIG. 1 is a partially exploded rear perspective view of a sweeper according to the invention
  • FIG. 2 is a schematic sectional side view of a sweeper according to the invention.
  • FIG. 3 is a sectional top view of a detail of a sweeper according to the invention.
  • a manually-operated sweeper according to the invention is generally designated by the reference numeral 10 .
  • the sweeper 10 is constituted by a wheeled chassis 111 with a steering handlebar 12 ; a container 13 for collecting dirt 28 is associated with said chassis.
  • the rear wheels 14 of the chassis 11 by virtue of their rotation, actuate by means of a first transmission a first brush 15 , whose axis is horizontal and parallel to the axis of the rear wheels 14 , said first brush being adapted to act on the surface below the chassis 11 .
  • the wheels 14 by means of a second transmission, also actuate a second brush 16 , which rotates with a vertical axis and is supported by an arm 17 which protrudes in front of the chassis 11 .
  • the sweeper 10 has, proximate to the first brush 15 , a fan 18 for aspirating fine dust 29 , raised by the action of the brushes, toward a filter 19 located within a rear protective housing 20 .
  • the chassis 11 has, at the fan 18 , a grille which opens onto the outside 21 for the escape of the filtered air.
  • the fan 18 is turned by way of transmission means which are actuated by the motion of the closest of the rear wheels 14 without the aid of any electric motor drive.
  • Said transmission means for the fan 18 which accordingly replace the electric motor drive provided in known types of sweeper, are constituted by a drive train of the internal-wheel type, provided by a drive wheel 22 , which is rigidly coupled to the rotation shaft 23 of the fan 18 and is in contact with the internal surface 24 of the rear wheel 14 , as shown clearly in FIG. 3 .
  • the wheel 14 applies to the drive wheel 22 torque by rolling friction.
  • the drive wheel 22 is made of a rubber-like material, and the wheel 14 and therefore its internal surface 24 are made of plastic material such as nylon or equivalents, and therefore the drive wheel 22 rotates substantially without slipping on the internal surface 24 .
  • the transmission ratio determined by the outside diameter of the drive wheel 22 and by the inside diameter of the internal surface 24 of the rear wheel 14 is such as to move the fan 18 at a rate which generates partial vacuum within the filter 19 .
  • the filter 19 has a cylindrical structure and is of the cartridge type.
  • the filter 19 is associated coaxially with the fan 18 by interposing a tube 25 .
  • the tube 25 has a larger cross-section in the region 25 a where it surrounds the fan 18 and a smaller cross-section in the region 25 b for coupling to the filter 19 .
  • the tube 25 is therefore shaped so as to obtain a Venturi effect, reducing the pressure in the filter 19 with respect to the pressure outside the fan 18 .
  • the drive wheel 22 at the free end of the rotation shaft 23 of the fan 18 therefore allows to save on the entire electrical system with which known types of sweeper are provided, i.e., the electric motor drive, the battery and the battery charger.
  • the sweeper 10 according to the invention further has the advantage of being lighter than known sweepers, since it lacks said electric power supply components and is therefore more maneuverable.
  • the first transmission for the first brush 15 is provided by a first driving gear 26 , which is keyed on a rotation shaft 27 of the rear wheel 14 , against which the drive wheel 22 is pressed, and by a second driven gear 28 , which meshes with the first gear 26 so as to form an external gear train and is keyed to a rotation pivot 29 of the first brush 15 .
  • the first brush 15 therefore rotates in the opposite direction with respect to the direction of travel of the sweeper 10 .
  • the present invention provides a manually-operated sweeper which is adapted to operate in a fully independent manner without using electric power.
  • the present invention provides a manually-operated sweeper in which the fan for aspirating fine dust is not actuated by an electric motor drive, but is actuated by mechanical means for transmitting the rotation of the rear wheels.
  • the present invention provides a sweeper whose functionality and efficiency is not lower than that of known types of sweeper.
  • the present invention provides a sweeper whose dirt loading capacity is not lower than that of known types of sweeper.
  • the present invention provides a sweeper which can be operated easily even by an operator who does not have particular prior training.
  • the present invention provides a manually-operated sweeper which can be manufactured cheaply with known systems and technologies.
  • the materials employed may be any according to requirements and to the state of the art.
