IV. Detailed Description of the Invention
IV. Detailed Description of the Invention
[0018] Referring now to the drawings wherein the showings are for purposes of illustrating embodiments of the invention only and not for purposes of limiting the same, and wherein like reference numerals are understood to refer to like components, 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. For the embodiment shown, the filaments are formed of a relatively stiff metal and thus the brush 10 may be considered to be a wire brush. Wire brushes, as is well known to those of skill in the art, 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. In one specific embodiment, 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 Page 5 of 16 in the art. In one embodiment, a handle 50 may extend from the tuft holder 40.
In another embodiment, the tuft holder 40 is itself used as a handle. It may have one or more textured regions 52 for this purpose.
[00191 With continuing reference to FIGURES 1-3, the brush 10 may have 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. For the embodiment shown, 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. For the embodiment shown, the brush 10 may include five predominately linear rows 60 of tufts 30 with two outside rows 62, two intermediate rows 64, and one middle row 66. The rows 60 may be parallel to the primary operation axis 54, as shown. The distal end of the two outside rows 62 may have a section that is curvilinear, as shown.
[00201 With reference now to FIGURE 2, to better discuss the orientation of the tufts 30 within the rows 60, note that the nearest outside row 62 is (except the distal portion) within a plane 22 that is parallel to the primary operation axis 54.
Note also 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. As shown in FIGURE 1, the tufts 30 in the visible outside row 62 are angled at a tuft angle TA 1. Tuft angle TAI 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 64 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 64, 62 may, in one embodiment, be similarly angled. Thus in this embodiment the positioning Page 6 of 16 and angling of the tufts 30 are mirror imaged around a longitudinal axis parallel to the primary operation axis 54.
[0021] With reference now to FIGURES 1-3, tuft angles TA I, 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 62 are shown to be angled at the same tuft angle TA1, it is also contemplated to have different tuft angles for the tufts 30 in the outside row 62. Similarly, while all the tufts 30 in the intermediate row 64 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 64. While the tuft angle TA1 is shown to be at the same angle as the tuft angle TA2, it is also contemplated to have TA 1 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). Of course 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 66, 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 66 at forward or backward angles.
[0022] With continuing reference to FIGURES 1-3, 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.
[0023] With reference now to FIGURES 4-6, another embodiment brush 10 is shown. This brush 10 includes tufts 30 arranged in rows 60. The brush 10 may include an Page 7 of 16 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.
[00241 With continuing reference to FIGURES 4-6, 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.
In one embodiment, 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. In one specific embodiment, 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.
[0025] With reference now to all the FIGURES, many variations of the brushes 10, 10 are contemplated with some variations including a layout of adjacent rows of tufts angled in alternate directions. Within each row 60, the tufts 30 can be substantially parallel to each other or the tufts 30 may have various other configurations.
For one non-limiting example, the tufts 30 within a row 60 may all be angled towards the front 16 of the brush, but at different angles. For another non-limiting example, the tufts may all be angled towards the front 16 of the brush and one side of the brush at 30 substantially the same angle. For another non-limiting example, the tufts 30 may all be angled towards the rear 18 of the brush at substantially the same angle, but at different Page 8 of 16 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.
[0026] Numerous embodiments have been described, hereinabove. It will be apparent to those skilled in the art that the above methods and apparatuses may incorporate changes and modifications without departing from the general scope of this invention. It is intended to include all such modifications and alterations in so far as they come within the scope of the appended claims or the equivalents thereof.
Having thus described the invention, it is now claimed:
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. For the embodiment shown, the filaments are formed of a relatively stiff metal and thus the brush 10 may be considered to be a wire brush. Wire brushes, as is well known to those of skill in the art, 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. In one specific embodiment, 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 Page 5 of 16 in the art. In one embodiment, a handle 50 may extend from the tuft holder 40.
In another embodiment, the tuft holder 40 is itself used as a handle. It may have one or more textured regions 52 for this purpose.
[00191 With continuing reference to FIGURES 1-3, the brush 10 may have 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. For the embodiment shown, 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. For the embodiment shown, the brush 10 may include five predominately linear rows 60 of tufts 30 with two outside rows 62, two intermediate rows 64, and one middle row 66. The rows 60 may be parallel to the primary operation axis 54, as shown. The distal end of the two outside rows 62 may have a section that is curvilinear, as shown.
[00201 With reference now to FIGURE 2, to better discuss the orientation of the tufts 30 within the rows 60, note that the nearest outside row 62 is (except the distal portion) within a plane 22 that is parallel to the primary operation axis 54.
Note also 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. As shown in FIGURE 1, the tufts 30 in the visible outside row 62 are angled at a tuft angle TA 1. Tuft angle TAI 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 64 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 64, 62 may, in one embodiment, be similarly angled. Thus in this embodiment the positioning Page 6 of 16 and angling of the tufts 30 are mirror imaged around a longitudinal axis parallel to the primary operation axis 54.
[0021] With reference now to FIGURES 1-3, tuft angles TA I, 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 62 are shown to be angled at the same tuft angle TA1, it is also contemplated to have different tuft angles for the tufts 30 in the outside row 62. Similarly, while all the tufts 30 in the intermediate row 64 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 64. While the tuft angle TA1 is shown to be at the same angle as the tuft angle TA2, it is also contemplated to have TA 1 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). Of course 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 66, 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 66 at forward or backward angles.
[0022] With continuing reference to FIGURES 1-3, 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.
[0023] With reference now to FIGURES 4-6, another embodiment brush 10 is shown. This brush 10 includes tufts 30 arranged in rows 60. The brush 10 may include an Page 7 of 16 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.
[00241 With continuing reference to FIGURES 4-6, 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.
In one embodiment, 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. In one specific embodiment, 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.
[0025] With reference now to all the FIGURES, many variations of the brushes 10, 10 are contemplated with some variations including a layout of adjacent rows of tufts angled in alternate directions. Within each row 60, the tufts 30 can be substantially parallel to each other or the tufts 30 may have various other configurations.
For one non-limiting example, the tufts 30 within a row 60 may all be angled towards the front 16 of the brush, but at different angles. For another non-limiting example, the tufts may all be angled towards the front 16 of the brush and one side of the brush at 30 substantially the same angle. For another non-limiting example, the tufts 30 may all be angled towards the rear 18 of the brush at substantially the same angle, but at different Page 8 of 16 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.
[0026] Numerous embodiments have been described, hereinabove. It will be apparent to those skilled in the art that the above methods and apparatuses may incorporate changes and modifications without departing from the general scope of this invention. It is intended to include all such modifications and alterations in so far as they come within the scope of the appended claims or the equivalents thereof.
Having thus described the invention, it is now claimed:
