Definitions

  • the invention relates to a sucking battery motor-brush for eleaning places and simularly acting sweeping machines, comprising a hollow framework with wheels and steering-drive handle, lodging an electric duster actuated by a series of batteries and an extractable dust container according to the preamble of claim 1.
  • Sucking motor-brush machines allow cleaning anywhere without the use of hand brushes, besoms, dust-bins and vacuum cleaners.
  • a debris pickup head assembly is known in accordance with prior art portion of Claim 1 (U.S. patent n.3,436,788) in which a pair of circular rotating brooms into a hood downside opened has a forward side with a flexible apron.
  • the electric dusters particularly, powered by noisy electrical motors with hindering wires, cannot collect bulky litter such as tins, papers, broken pieces, cigarette-ends and so on.
  • the invention - as claimed in claim 1 - is intended to remedy these drawbacks and solves the problem of how to engineer and make available a particular solution of a mini sucking battery motor-brush.
  • Fig. 1 of the sheet 1 is a perspective view of the invention from the top right with the structure of the motor-brush and the placing of its components.
  • Fig. 2 of the sheet 2 shows the two bolt -adjusters movable along the slot by means of two supports which hold the two motor-reducers where the brushes are assembled in a position touching themselves.
  • Fig. 3 of the sheet 2 shows the whole movable brush-holder block where two other supports are rivetted.
  • Fig. 4 of the sheet 3 shows the framework of the motor-brush, the extractable container, the shoot and all the necessary parts for the intake.
  • the figures show a mini sucking battery motor-brush and similarly acting machines essentially comprising a hollow framework 22, provided with wheels 11 and steering-drive handle 1, housing an electric duster 7 and an extractable closed dust container 25.
  • the handle 1 turns by means of a ball joint 2 is connected to the lever 3 which going into the slot 4 automatically acts the electric circuit with a switcher 5 passing power from the battery of the accumulators 6 to the electric duster 7 and to the motor reducers 8 which permits the two rotating brushes 9 to work.
  • These brushes formed by a plurality of radial flexible filaments, are counter-revolving from the inner to the outer side, extended from the framework 10 and of the wheels 11 so collecting litter and dust in the centre and in the corners of the room floor 24 (either in the right or in the left) converging it to the centre.
  • the two bolt-adjusters 12 must be loosened allowing to run along the slots 13 the two supports 14 which hold the two motor reducers 8 where the brushes 9 are assembled, until they are closer to the centre and touch themselves as is shown in the Fig. 2 of sheet 2.
  • This block 18 is hinged on the pin 19 and the whole weight of motor-reducers 8 and of supports 16 loads on the brushes 9.
  • the handle 1 is joined to the pin 20 pressing on the plate 21 and the movable block brush holder 18 is fixed to this plate 21 by a pin 19.
  • the handle 1 is provided with a lever 3, that taking it place in the slot 4 activates the switcher 5 which stops the electric duster 7 or motor-reducers 8.
  • the supports 14 hold two motor-reducers 8 which permit the brushes 9 to turn to the opposite direction making pressure on the small plate 21 and allowing it turn on the pin 20, of Fig. 1 - sheet 1, through the hole 23, of Fig. 3 - sheet 2, that allows the lowering and rising of the movable brush-holder block 18.
  • the framework 22 runs on the floor 24 on two wheels 11, of Fig. 1 - sheet 1, which are diametrically opposed to each other; it is positioned into the holes 27, of Fig. 4 - sheet 3, by the roll 28 located between the two supports 29, which turns on the pin 30.
  • the shoot 26 and 32 important element of the motor brush, is made up of two parts:the first 26 is supported by two holes 29, by the pin 30 and by two fixed supports 33 of the framework 22; the second 32, which is consumable, is rivetted on the ball joint part 26 by three bolts 34.
  • the consumable part 32 which adheres to the floor 24, has been built with a wide flat surface, for these reasons:
  • the shoot 26 - 32 is an inclined and articulated plane which adheres to the floor 24 even in the small depressions and reliefs and allowing the two brushes 9 to collect the rubbish, to lift and throw it into the closed container 25.
  • the electric duster 7 is connected to the vertical suction conduit 39 through the slot 40.
  • the conduit 39 is closed by a hermetic cover seal 44 and continues horizontally with the duct 41 which is joined to the conduct 42.
  • the conduct 42 has an opening 46, a floodgate 45 and is subdivided in two air intakes 35 and 35.
  • the conduct 42 is a rubber-made part, fixed by screws to the part located under the framework 22 and is connected (like the Fig. 1 - sheet 1 shows) to the vertical suction conduit 39 set on the framework 22.
  • the conduct 42 made of rubber or other flexible material thus obtaining the two flexible tongues 43, avoids their breakage when skimming the floor 24 surface.
  • the above conduct 42 - which carries the duct 41 with the two intakes 35 and 35 - may be obtained directly on the framework 22, by pressing or fusion systems, creating two tongues 43 with rubber strips fixed by screws to the air intakes 35 and 35.
  • the working of the mini sucking battery motor-brush is briefly specified as follows. To move and operate it is sufficient just to grip the handle 1, turn it by the ball joint 2 a quarter of turn from right to left setting the lever 3 free from the slot 4 which automatically turns on the switcher 5 passing power from the battery accumulators 6 to the electric duster 7 and to the motor reducers 8 which will allow the two brushes 9 to work .
  • These brushes 9 are counter-revolving from the inner to the outside and stretch out the framework 10 provided with wheels 11 they collect litter and dust in the corners of the room floor 24 either to the right or the left converging them to the centre. After some working time the brushes 9 will be consumed and they must be adjusted by setting them closer to each other and secondly by putting them down.
  • the handle 1 To keep the brushes 9 lifted of the ground 24 the handle 1 must be turned from left to right using the joint 2 and allow the lever 3 to place itself in the slot 4 which is a part of the framework 22.
  • the whole movable brush-holder block 18 is a movable support where two other supports 14 are rivetted; these ones hold two motor-reducers 8 which permit the brushes 9 to turn in the opposite direction and makes pressure on the small plate 21 and lets it turn on the pin through the hole 23, that allows lowering and raising of the movable brush-holder block 18.
  • the framework 22 runs on the floor 24 on two wheels 11 which are diametrically opposed to each other; it is positioned into the holes 27 by the roll 28 located between the two supports 29, which turns on the pin 30.
  • the framework 22 is provided with two holes 31 where there is a pin 19 supporting the whole movable brush-holder block 18.
  • the consumable part 32 of the shoot 26-32 adheres to the floor 24 by virtue of its wide flat surface.
  • the inclined and articulated shoot 26-32 skims the surface of the floor 24 even in small depressions and reliefs and allows the two brushes 9 to collect the rubbish, to lift and to throw it into the closed container 25.
  • the brushes 9, when working, carry to the centre of the floor 24 rubbish and dust, but - fails to let them totally pass into the container 25 - leaving in the centre of the floor a thin strip of fine dust and dust in the air, outside the two opposite air intake openings 35 and 35.
  • the above lower part 38 is connected to the suction conduit 39 through the slot 40.
  • the electric duster fan 7 creates vacuum in the framework 36 by intaking clean air through the filter 37, depositing the dust in the lower part 38.
  • the electric duster fan 7 sucks the dust strip let on the floor 24 by brushes 9 after the shoot 26-32 and sucks up the fine dust lifted by the two brushes 9 outside the machine through the two air intake openings 35 and 35.
  • the filter 37 After some time of use the filter 37 must be cleaned.
  • the slot 4 in the framework 22 lets pass the lever 3 to put the switcher 5 on.
  • the holes 48 are provided for the three screws which secure the switcher 5.
  • the four holes 49 are for the screws which fix the small block 50.
  • This shoot 26-32 in effect allows to collect dust, small and bulky litters (like papers, cigarette-ends, metal tins, etc.). It reduces the framework 22 size and by consequence the machine needs the minimal power for working.
  • the shoot 26-32 is a very important and essential element of the invention and may be built in different sizes and applied in many ways without modifying its specified peculiarities.
