Definitions

  • the present invention relates to hand held cleaning apparatus having a reciprocating or rotating brush head.
  • Household cleaning is a never ending business. Although there are numerous types of sponges and brushes that are specially designed to clean large, open surface areas such as countertops, sinks, and bathtubs, there are fewer resources available for cleaning the difficult cracks, corners, and other hard to reach areas that are ubiquitous in a home. Although conventional sponges and brushes can certainly be used for cleaning corners and other hard to reach areas, the configuration and large size of such conventional cleaners makes them difficult to access such areas. The user is often required to apply extensive force by the ends or tips of the fingers so as to force the cleaner into the crack or corner to be cleaned. Such cleaning is tiring and often results in cramping of the hand and/or fingers.
  • toothbrushes are often used to clean such hard to reach areas.
  • the problem with toothbrushes is that because they are specifically designed for cleaning teeth around sensitive gums, toothbrushes are typically too soft and do not have a good angle for any extended, aggressive scrubbing of hard surfaces.
  • any significant scrubbing using a toothbrush again produces fatigue and cramping of the hand.

  • the present invention relates cleaning apparatus having a reciprocating or rotating brush head.
  • the cleaning apparatus is generally designed for domestic use in cleaning small, hard to reach areas such as cracks, corners, grooves and crevices.
  • the cleaning apparatus can be used for cleaning corners and around faucets on counter tops and in showers. It can also be used for spot scrubbing materials such as fabric and carpets. It is appreciated, however, that the apparatus can be used for cleaning any type of surface in commercial, residential, or any other application.
  • the cleaning apparatus is not designed for use as a toothbrush.
  • Cleaning apparatus 4 generally comprises a body assembly 5 having a removable head assembly 6 .
  • Head assembly 6 includes a head housing 7 having an upper head housing 22 which mates with a lower head housing 24 .

  • Head assembly 6 further includes a rotatable brush head 14 having a brush 16 mounted thereon.
  • brush head 14 comprises an annular carrier plate 122 having a top surface 124 and an opposing bottom surface 125 .
  • a plurality of tufting holes 170 are formed on bottom surface 125 .
  • tufting holes 170 are circular and each have a diameter in a range between about 1 mm to about 4 mm with about 2 mm to about 3 mm being more common. Tufting holes 170 are shown disposed in concentric rings. Alternatively, tufting holes 170 can also be randomly disposed or be in other patterns.
  • tufting holes 170 from an outer ring 172 , a middle ring 174 , an inner ring 176 and a center tufting hole 178 .
  • a tuft 180 disposed within each tufting hole 170 is a tuft 180 which is comprised of a plurality of bristles 182 .
  • the combined tufts 180 form brush 16 .
  • Bristles 182 can be made of a variety of different materials having different lengths and diameters. By adjusting the properties of the bristles 182 , brush 16 can be formed having different stiffnesses to better suite different uses. In general, bristles having shorter length and increased diameter have increased stiffness.
  • Bristles 182 can be made from a variety of different natural or synthetic materials.
  • bristles 182 are comprised of a polymer material such as nylon.
  • bristles 182 can be comprised of a metal such as brass, stainless steel, or copper.
  • each bristle has an exposed length L which is typically in a range between about 0.3 cm to about 2.5 cm with about 1 cm to about 2 cm being more common.
  • the depicted brush 16 has a substantially cylindrical configuration with a maximum diameter D that is typically in a range between about 1 cm to about 5 cm, with about 1 cm to about 3 cm being common, and about 1.5 cm to about 2.5 cm being more common. Larger brushes may have a diameter in a range from about 3 cm to about 5 cm.
  • brush 16 can have any desired configuration and can have any desired dimensions, including longer lengths and diameters, so as to function for a particular purpose.
  • head assembly 6 is removable from body assembly 5 , it is appreciated that a variety of different head assemblies 6 can be made, each having a brush 16 of different configuration and/or properties.
  • head assembly 6 can be formed each having a brush 16 with soft bristles, medium bristles, stiff bristles or combinations thereof.
  • the soft bristles are comprised of a polymeric material having a diameter in a range between about 0.15 mm to about 0.25 mm with about 0.18 mm to about 0.23 mm being more common.
  • Medium polymeric bristles typically have a diameter in a range between about 0.30 mm to about 0.48 mm with about 0.37 mm to about 0.42 mm being more common.
  • polymeric stiff bristles typically have a diameter in a range between about 0.48 mm to about 0.75 mm with about 0.52 mm to about 0.58 mm being more common.
  • bristles on tooth brushes typically have a diameter less than 0.15 mm so that the bristles are not so stiff as to damage the gums or enamel of the teeth.
  • tufting holes 170 in outer ring 172 , middle ring 174 , and inner ring 176 are filled with medium bristles while center tufting hole 178 is filled with stiff bristles forming a stopping tuft.
  • the bristles in the stopping tuft are shorter than the other bristles.
  • the stiffness of the stopping tuft helps limit the collapse of the other tufts as the brush is pressed against the surface to be cleaned. This helps to ensure that the tips of the bristles, as opposed to the sides, are primarily used for scrubbing. Bristles having different properties can also be defined by relative percentages.
  • the bristles of the cleaning tufts can have a length that is at least 20% longer or at least 30% longer than the bristles of the stopping tuft and a diameter that is at least 30% smaller or at least 40% smaller than the bristles of the stopping tuft.
  • brush 16 can comprise a group of central tufts 8 which are surrounded by outer perimeter tufts 9 .
  • the outer perimeter tufts 9 are slightly longer and softer than central tufts 8 .
  • light contact by brush 16 produces soft scrubbing by outer perimeter tufts 9 while harder biasing of brush 16 causes central tufts 8 to engage the surface, thereby producing harder scrubbing.
  • all the tufts/bristles can be the same length, diameter, or stiffness or any combination of lengths, diameters and stiffness can be used.
  • Body assembly 5 includes a body housing 12 having a substantially cylindrical configuration.
  • Body housing 12 can have a circular, elliptical or any other desired transverse cross section and is sized to comfortably fit within the hand of a user.
