Definitions

  • the present invention relates generally to brushes, and more specifically to brushes having some rows of tufts angled forward and other rows of tufts angled backward.
  • brushes include a tuft holder having tufts that extend at right angles from the tuft holder.
  • FIGURE 7 It is also known, as shown in FIGURE 7 , to provide a wire brush 200 having a tuft holder 202 with tufts 204, some of which that extend at non-right angles.
  • This known arrangement uses two grouping of tufts 206, 208, where each grouping uses tufts that are splayed or flared, as shown.
  • US 2005/0268414 A1 discloses a toothbrush which has a triple cross array of tufts of bristles, wherein the tufts are disposed in rows which are disposed on a diagonal relative to longitude and axis of the toothbrush.
  • EP 0 221 000 A1 discloses an orthodontic toothbrush.
  • a brush is provided as defined in claim 1.
  • a brush may comprise: a tuft holder; a primary operation axis; a handle that extends from the tuft holder substantially along the primary operation axis; a first linear row of tufts that comprises at least first, second, and third tufts that are formed of a metal and that extend from the tuft holder; and, a second linear row of tufts that comprises at least first, second, and third tufts that are formed of a metal and that extend from the tuft holder.
  • the first and second rows of tufts are substantially parallel to the primary operation axis.
  • the first tuft of the first row and the first tuft of the second row form an X-shape when viewed from a position that is perpendicular to the primary operation axis.
  • the second tuft of the first row and the second tuft of the second row form an X-shape when viewed from a position that is perpendicular to the primary operation axis.
  • the third tuft of the first row and the third tuft of the second row form an X-shape when viewed from a position that is perpendicular to the primary operation axis.
  • This brush is that the angled brushes perform better scrubbing action.
  • FIGURES 1-3 show a brush 10 having rows of tufts 30, a tuft holder 40, and a handle 50.
  • a tuft 30 can include one or more filaments or bristles 20.
  • the specific number of filaments or bristles used to make up one tuft 30 can be any number chosen by a person of ordinary skill in the art.
  • the filaments or bristles may be made from a variety of natural materials or fibers or from synthetic materials including, for non-limiting examples, nylon or polyester.
  • the filaments are formed of a relatively stiff metal and thus the brush 10 may be considered to be a wire brush.
  • Wire brushes are generally intended for use in scraping undesired materials, such as paint or rust, off of a surface. After the undesired materials are removed, if desired, the now clean surface may be painted, stained or otherwise treated.
  • the bristles 20, and thus the tufts 30, are formed of stainless steel. Each tuft 30 can be secured to the tuft holder 40 with a staple, a wire, a screw, adhesive, epoxy or any other fastening means chosen by a person of ordinary skill in the art.
  • a handle 50 may extend from the tuft holder 40.
  • the tuft holder 40 is itself used as a handle. It may have one or more textured regions 52 for this purpose.
  • the brush 10 has a primary operation axis 54.
  • the primary operation axis is the axis along which the brush performs best as it is moved over the surface it is being used on.
  • the handle 50 extends from the tuft holder 40 along the primary operation axis 54.
  • the tufts 30 may be arranged in rows 60.
  • the number, type, and shape of rows can be any chosen with the sound judgment of a person of skill in the art.
  • the brush 10 may include five predominately linear rows 60 of tufts 30 with two outside rows, two intermediate rows, and one middle row.
  • the rows 60 may be parallel to the primary operation axis 54, as shown.
  • the distal end of the two outside rows may have a section that is curvilinear, as shown.
  • the nearest outside row is (except the distal portion) within a plane 22 that is parallel to the primary operation axis 54.
  • plane 24 which is perpendicular to the plane 22 and parallel to the primary operation axis 54.
  • Each row similarly is within a plane that is parallel to the primary operation axis 54 and perpendicular to the plane 24.
  • the tufts 30 in the visible outside row are angled at a tuft angle TA1.
  • Tuft angle TA 1 is considered a forward angle because the distal end of the tuft 30 is more forward (toward the distal end of the brush 10) than the base of the tuft 30 (where it extends from the tuft holder 40).
  • the tufts 30 in the visible intermediate row are angled at a tuft angle TA2.
  • Tuft angle TA2 is considered a backward angle because the distal end of the tuft 30 is more backward (toward the proximal, handle end of the brush 10) than the base of the tuft 30 (where it extends from the tuft holder 40). It was discovered that this alternate angled arrangement of the tufts 30 in neighboring rows 60 provides improved performance when the brush 10 is used along its primary operation axis 54.
  • the intermediate and outside rows may, in one embodiment, be similarly angled.
  • the positioning and angling of the tufts 30 are mirror imaged around a longitudinal axis parallel to the primary operation axis 54.
  • tuft angles TAI, TA2 can be any chosen with the sound judgment of a person of skill in the art. Note that the tuft angles are expressed as acute angles. In one embodiment, the tuft angles are between 60 degrees and 87 degrees, inclusively, and in another embodiment, 75 degrees and 87 degrees, inclusively. In still another embodiment, the tuft angles are between 80 degrees and 85 degrees, inclusively. While all the tufts 30 in the outside row are shown to be angled at the same tuft angle TA I, it is also contemplated to have different tuft angles for the tufts 30 in the outside row.
  • tufts 30 in the intermediate row are shown to be angled at the same tuft angle TA2, it is also contemplated to have different tuft angles for the tufts 30 in the intermediate row. While the tuft angle TA I is shown to be at the same angle as the tuft angle TA2, it is also contemplated to have TAI and TA2 at different angles. If the tufts 30 in neighboring rows 60 are arranged as shown, they form an X-shape when viewed from a position that is perpendicular to the primary operation axis 54 (as shown in FIGURE 1 ).
  • the spacing and arrangement of the tufts 30 can be such that, in another embodiment, the use of tuft angles TAI and TA2 do not form an X-shape.
  • the tufts 30 in the middle row may be at right angles with respect to the plane 24. Thus, they are shown to have a tuft angle of 90 degrees. It is also contemplated to arrange the tufts 30 in the middle row at forward or backward angles.
  • any of the rows it is also contemplated to provide one or more of the tufts for any of the rows to have an inward angle (the distal end of the tuft 30 is more toward the inside of the brush 10 than the base of the tuft 30) or an outward angle (the distal end of the tuft 30 is more toward the outside of the brush 10 than the base of the tuft 30) if desired.
  • the brush 10 includes tufts 30 arranged in rows 60.
  • the brush 10 may include an outside row 70, which can extend around at least a portion of the perimeter of the tuft holder 40.
  • the brush 10 may include an inside row 72 positioned adjacent the outside row 70.
  • the outside row 70 may angle out at between 75 degrees and 85 degrees inclusively measured from a horizontal plane on the tuft holder 40. In a specific embodiment, the outside row 70 may angle out at approximately 82.5 degrees.
  • the intermediate row 72 may angle out at between 75 degrees and 89 degrees inclusively measured from a horizontal plane on the tuft holder 40. In a specific embodiment, the outside row 70 may angle out at approximately 86.2 degrees.
  • the brush 10 may include a center field of rows 74 adjacent the inside row 72.
  • the center field 74 may include one or more rows 60 of tufts 30.
  • the rows 60 may extend along the longitudinal axis of the brush 10, along the transverse axis of the brush 10, or any direction including, but not limited to, diagonal.
  • the tufts 30 may be arranged so the rows 60 extend along two axes, for one non-limiting example, along both the longitudinal and transverse axes.
  • the center field includes nine rows 60 of tufts 30. One row 60 is angled towards a first end 16 of the brush 10 and the adjacent row 60 is angled towards a second end 18 of the brush.
  • the center field 74 includes nine rows 60 with the first, third, fifth, seventh, and ninth rows 60 angled approximately 81 degrees toward the first end 16, measured from a horizontal plane on the tuft holder 40; and the second, fourth, sixth, and eighth rows 60 angled approximately 81 degrees toward the second end 18, measured from a horizontal plane on the tuft holder 40.
  • the tufts 30 can be substantially parallel to each other or the tufts 30 may have various other configurations.
  • the tufts 30 within a row 60 may all be angled towards the front 16 of the brush, but at different angles.
  • the tufts 30 may all be angled towards the front 16 of the brush and one side of the brush at substantially the same angle.
  • the tufts 30 may all be angled towards the rear 18 of the brush at substantially the same angle, but at different angles to the sides of the brush.
  • a first row 60 may have many different configurations, and an adjacent second row 60 may have a mirror configuration of the first row 60. The second adjacent row may be substantially parallel to the first row or the adjacent row may be offset at an angle to the first row.
