  • the present invention relates to a floor sweeper for the purpose of collecting and sweeping up the dust lying on a comparatively even and smooth surface of floor such as concrete floor, boarded floor and tiled floor.
  • the dust guiding plate is usually disposed to be slightly distant from the floor surface.
  • this countermeasure has entailed a defect that part of the dust collected by the brush escapes by way of the opening between said dust guiding plate and the floor surface to be left unswept.
  • Principal object of the present invention is to provide a floor sweeper wherein the brush for sweeping the dust lying on the floor is pivotally mounted on a housing so as to rotate in the direction crossing the direction of travel of said housing and the dust receiver is disposed both in front and the rear of the housing along the direction of travel thereof to face the brush.
  • Another object of the present invention is to provide a floor sweeper wherein the dust guiding plate for the purpose of leading the dust collected by the brush from the floor surface into the dust receiver is disposed in the direction parallel with that of travel of the housing and the lower end of said dust guiding plate is devised to face the brush and come into sliding contact with the floor surface lest the dust should be left unswept.
  • a further object of the present invention is to provide a floor sweeper, wherein the rollers are installed both in front and the rear of the housing, and the cavity surrounding the brush is to be closed to the floor by virtue of said guiding plate, thereby preventing the floating dust around the brush escaping from the cavity to the outside.
  • a still further object of the present invention is to provide a floor sweeper wherein the brushes rotatable in the direction crossing the direction of travel of the housing are installed bilaterally along the center line of the housing in the direction of travel thereof.
  • FIG. 2 as out along the line IV-IV FIG. 5, is a longitudinal section as cut along the line VV of FIG. 6 and is illustrative of another embodiment of the present invention
  • FIG. 6 is a transverse section as cut along the line VIVI of FIG. 5,
  • FIG. 7 is a longitudinal section as out along the line VII-VII of FIG. 5,
  • FIG. 8 is a longitudinal section as cut along the line VIIIVIII of FIG. 9 and is illustrative of still another embodiment of the present invention.
  • FIG. 9 is a transverse section as cut along the line IX-IX of FIG. 8, and
  • FIG. 10 is a longitudinal section as cut along the line XX of FIG. 8.

Further, above the roller 11, there is installed the partition 22 which projects down from the upper cover plate 3 toward the roller 11 to be close thereto as shown in FIG. 4.
  • the brush extends across the complete width of the housing.
  • the width of the brush 7a is contracted a little, while the dust receiver 8a is installed on either the fore or the back of the housing 2 along the direction of travel thereof, the dust inlet port 19a opens above the side of the brush 7a and a guide plate 23 confronting said dust inlet port 19a as well as the top of the brush 7a is at a fixed angle (usually 45) and is fixed to the upper cover plate 3.
  • the dust guiding plate 9a is fixed on the lower part of the side cover plate 4.

  • the brushes 7b, 7b having a comparatively narrow width similar to that in the foregoing embodiment shown in FIGS. 5, 6 and 7 are installed bilaterally along the center line of the housing in the direction of travel thereof, and on one side of each brush 7bv and 7b, there is provided the dust receiver 8b having a structure similar to the dust receiver 8 in the foregoing embodiment shown in FIGS. 1, 2, 3 and 4, while on the other side of each brush 7b and 7b, there is provided the dust receiver 8b having a structure similar to the dust receiver 8a in the foregoing embodiment shown in FIGS. 5, 6 and 7.
  • Other details of the construction are the same as that in the foregoing two embodiments and, therefore, the explanation thereof is abridged herein by assigning identical numbers to the corresponding parts in these embodiments.
  • each of the brushes 7, 7a, 7b and 7b in the foregoing embodiments is shown as being providied on an endless belt, but these brushes may be directly provided on the belt-driving shafts 14.
  • a dust receiver also between the two belt-driving shafts 14. It of course will do to employ only one belt-driving shaft. Further, though the brush in each'embodiment.
  • the dust guiding plate 9 slides on the floor surface and the rollers 1 1 roll on the floor surface, thereby depressing bulky dust.
  • the cavity 10 surrounding the brush 7 is kept close to the floor surface, so that even when a fine dust is made to float in the air by the rotation of the brush 7, it flows to the outside of this cavity 10.
  • the brushes 7b and 7b are devised to rotate in opposite directions.
  • the dust collected is swept up along the dust guiding plate 9b disposed in the direction of rotation of the brush 7b and is directly taken in the dust receiver 8b disposed in the same direction.
  • the dust collected is swept up along the dust guiding plate 9b disposed on the opposite side, is thrown out by centrifugal force at the point where the brush 7b parts from the dust guiding plate 9b, strikes against the guide plate 23b and is deflected into the dust receiver 8b.
