  • This invention relates to a hand cleaner of the rotary brush type having a simple structure, which can be operated very effectively to exhibit a high cleaning efficiency.
  • a hand cleaner of the rotary brush comprising a rotary brush and a driving wheel, each being projected through the lower face of the cleaner body, wherein by gripping the cleaner body by a hand and moving the driving wheel while pressing it directly against the surface to be cleaned, the rotation of the driving wheel is transferred to the rotaty brush.
  • the width of the driving wheel is narrow and the driving wheel is provided on the'side of the cleaner body. Accordingly, it frequently happens that the driving wheel makes a slip and causes a racing and a sure rotation cannot be attained. Further, in case the driving wheel is not contacted with or pressed against the surface to be cleaned because converse or concave surfaces are present to be cleaned or because the width of the surface to be cleaned is narrow, the driving wheel is not rotated sufficiently.
  • FIG. 1 is an exploded perspective view of a hand cleaner embodied the invention
  • FIG. 2 is a bottom plan view of the hand cleaner of FIG. 1;
  • FIG. 3 is a partially cut-out, sectional view along the axis of a rotary brush
  • FIG. 4 is a sectional view taken along the line 4-4 of FIG. 2;
  • FIG. 5 is a sectional view taken along the line 55 of FIG. 2.
  • the cleaner body is made, as shown in FIG. 1 and FIG. 3, as two separate parts and 11, the upper part or cover Ml being provided with hook-shaped flanges 12 which snap over and engage with grooves 13 on the lower part or housing 11 when the two parts are assembled together.
  • the housing 11 has end walls 14 and 15 and a partition wall 16 which is positioned in parallel to one of the end walls (i.e., the right end wall 15 in FIG. 1) a small distance therefrom.
  • the bottom wall 17 of the housing has an oblong opening 18 which extends between the end wall 14 and the partition wall 16.
  • Protective edge 19 of a quaterly arc form extending upwardly into the interior of the cleaner body is formed on each side in the longitudinal direction of the opening 18 between the end wall 14 and the partition wall 16.
  • Shafts 20 are rotatably mounted between the end walls 14 and 15 inside and below the respective protec tive edges 19.
  • Each of the shafts 20 serves as the axle of a pressing rollers 21 which rollers are made of rubber.
  • the shaft 20 is also provided with a toothed wheel 22 which is disposed in between the partition wall 16 and the end wall 15.
  • the outer diameter of the wheels 22, shown in FIGS. 2 and 4 are made slightly smaller than that of rubber rollers 21.
  • the shaft 23 of a radial rotary brush 24 is rotatably mounted between approximately central points of the end walls 14 and 15 and is provided at an end portion thereof with a toothed wheel 25 which is disposed between the partition wall 16 and the end wall 15.
  • the brush shaft 23 is so arranged that the lower edge of the rotary brush 24 is positioned slightly below the lower edges of the pressing rollers 21 and in slight contact with the peripheral surfaces of the rubber rollers.
  • a free wheel 26 is journalled on a shaft 27 just above the toothed wheel 25 between the end wall 15 and partition wall 16.
  • a continuous belt engages wheels 22, 25, and 26 such that a rotation of either of the wheels 22, as shown in FIG. 4, is transmitted to the wheel 25.
  • the continuous belt 28 is disposed on the wheels 22, 25 and 26 such that a rotation of the wheels 22 in one direction produces a rotation of wheel 25 in the opposite direction.
  • the belt 28 is provided at regular intervals with perforations 29 which engage with the teeth of the wheels 22 and 25 in order to prevent the belt from slipping.
  • a spring 30 is provided to give suitable tension to the continuous belt 28.
  • Scraper pieces 31 are provided to extend from the corners of the bottom wall 17 on the side of the right end wall 15 straightly toward the vicinity of the crossing point of the inner face of the partition wall 16 and the opening 18. These scraper pieces may be of a soft rubber, plastic, cloth or brushes planted in lines.
  • the cleaner body is gripped by a hand and is rolled on the surface such as a table or a garment to be cleaned or brushed with the rubber pressing rollers 21 pressed on the surface.
  • the rotary brush 24 is rotated in a direction opposite to the rotation of the rubber rollers inasmuch as the brush 24 is disposed on wheel 25. Accordingly, dusts which are present on the table surface in the region in which the cleaner body is moving, are first pressed by the rubber rollers 21 and then flipped upwardly in the direction of the movement of the cleaner body by means of the rotary brush 24. Dust which is brushed into the cleaner body via the rotary brush 24 first strikes the protective edges 19 and then is deposited on the bottom 17 of the housing 1 1.
  • pressing rollers 21 are provided on both sides of the radial rotary brush 24. Dust, which is pressed against the surface to be cleaned by means of rubber pressing rollers 21, adheres to the surface of the rollers. After the dust travels on the surface of the rollers, it comes into contact with the rotary brush 24. At this point the dust is brushed into the interior of the housing of the cleaner body because of the frictional contact between the pressing rollers 21 and the rotary brush 24. The dust is prevented from spilling out of the housing because it generally falls on the outer sides of the protective edges 19 and is deposited on the bottom 17 of the housing.
  • fine dust which cannot be easily collected by the rotary brush 24 are pressed by the pressing rollers 21 and adhere or fix onto the surface of the pressing rollers where said dust is scrapped or brushed off by the rotary brush and is forwarded into the interior of the housing 11.
  • the pressing rollers 21 transfer any rtation to the rotary brush 24 as hereinbefore discussed, any time a pressing roller is in contact with a surface to be cleaned, the rotary brush 24 is being rotated. Moreover, the pressing rollers are disposed along almost the entire width of the cleaner body and thus if only a part of the pressing roller is in contact with any surface to be cleaned, the rotary brushes are being rotated and collecting dust.
  • the hand cleaner of this invention it is possible with use of the hand cleaner of this invention to clean the convex surface or cylindrical surface having a width narrower than the width of the cleaner body, for instance, a garment being worn on a body, a seat or back of a chair and a round or angular surface.
  • pressing rollers 21 are provided on both the sides of the radial brush 24, even when one of the rollers 21 floats off the surface to be cleaned and has no contact therewith, the cleaning can be accomplished conveniently without any troubles inasmuch as the radial brush 24 can be rotated so long as there is one pressing roller in contact with the surface to be cleaned.
  • the rotation of the rotary brush 24 by the rollers 21 may be accomplished by either a toothed wheel system in the presently preferred embodiment, or by a conventional friction means or a driven gear system such as is known in the art.
  • Scraper pieces 31 are mounted to collect dust present on both sides of the driving wheels 22 and introduce said dust into the pressing rollers 21, whereby the effective cleaning range can be broadened.
  • a hand-held belt driven, rotary brush cleaner for cleaning a wide variety of surfaces comprising:
  • driving wheels mounted in said cleaner body, said driving wheels connected to said pressing rollers and to said rotary brush by a belt such that rotation of said pressing rollers in one direction causes said rotary brush to rotate in the opposite direction;
