Numerous United States patents have been issued for various brushes, some of which are for suede, while others of which are for shoes. Known to applicant are U.S. Pat. Nos. D281,035; D289,109; D305,480; D307,216; D355,734. D364,275; D372,585; D389,318; D413,445; D425,707; D433,817; D439,414; U.S. Pat. Nos. 4,399,580; 5,213,430; 5,437,075; 5,596,785; 5,865,554; 5,978,999 and 6,032,316.
This invention provides a brush, which in one of its aspects is a brush for suede shoes, where the brush includes a preferably one-piece, preferably molded plastic handle, preferably having a hollow interior. The handle includes a preferably planar, outwardly-facing bristle-mounting surface, a collar extending annularly around the bristle-mounting surface, and a gripping portion extending centrally from the collar in a direction transverse to and oppositely from the bristle-mounting surface.
In one aspect of the invention, the gripping portion preferably has three generally vertically-extending surfaces, two of which are preferably parallel and spaced from one another, with the third surface joining each of the parallel surfaces. The gripping portion preferably further includes a convex, curved fourth surface extending upwardly and transitioning into the third surface at a position maximally remote from the bristle-mounting surface. The parallel spaced surfaces each preferably include generally centrally positioned exteriorly facing surface portions raised from the area therearound with the central surface portions including areas of depression formed in the raised surface portions. The areas of depression facilitate manual gripping of the brush. The fourth surface preferably includes a plurality of transversely extending protrusions formed thereon. The protrusions are preferably substantially equally spaced from one another along the fourth surface from the collar to the transition into the third surface.
In this aspect of the invention, the brush further includes bristles preferably embedded in and extending outwardly from the bristle-mounting surface. In this aspect of the invention, the brush preferably further includes a hollow, removable, rubber erasing sleeve configured with interior surfaces substantially matching the surfaces of the gripping portion of the handle. The hollow, removable rubber sleeve is shaped and sized for essentially complemental fitting over the gripping portion of the handle and for complementary contacting the annular collar. The sleeve preferably includes apertures in the parallel surfaces which are sized for complemental fitting about the raised exteriorly facing surface portions of the parallel spaced surfaces of the gripping portion. The fourth surface of the sleeve preferably includes a plurality of transversely extending sacrificial protrusions thereon, substantially equally spaced from one another along the fourth surface and proximate the juncture of the fourth surface with the collar. The sacrificial protrusions are for erasing contact with a suede shoe surface to be cleaned.
In another one of its aspects, this invention provides a brush for suede or any other napped material (for example, but not meant to limit the invention, corduroy).
In a preferred aspect the invention provides a brush for suede shoes. The brush comprises a handle which has an outwardly facing bristle mounting surface and a gripping portion extending away from the bristle mounting surface with the handle further including at least one exterior flat surface fitment for retaining an erasing sleeve when positioned thereon, where the gripping portion includes a plurality of protrusions formed thereon for resisting sliding removal of the sleeve when positioned over the handle and engaging the fitment. In this aspect of the invention, the bristles are preferably mounted on and extend from the bristle mounting surface. In this aspect of the invention, the removable erasing sleeve is preferably configured for complementally contacting the gripping portion and includes at least one second fitment formed therein for engaging the first surface fitment of the gripping means and precluding sliding removal of the sleeve from the gripping portion.
In this second aspect of the invention, the bristles are preferably of length varying with bristle positioned along at least one direction of the mounting surface to provide a wave-like configuration of bristle ends opposite those at the mounting surface. In the second aspect, the brush preferably further includes at least one sacrificial protrusion formed on the erasing sleeve for sacrificial erasing contact with the suede shoe, or other napped material object, having a surface to be cleaned and further preferably includes a plurality of such sacrificial protrusions formed on the erasing sleeve, with the sacrificial protrusions substantially equally spaced from one another along a fourth surface (of the sleeve) proximate juncture thereof with a collar, for erasing contact with a surface to be cleaned. The sleeve is preferably rubber and the bristles are preferably embedded in the bristle mounting surface.
In yet another aspect of the invention, the sleeve includes a plurality of exteriorly facing surfaces extending away from the bristle mounting surface of the handle when the sleeve is positioned on the handle, with first and second sleeve surfaces being spaced from one another and with the third sleeve surface joining each of the first and second sleeve surfaces. A fourth sleeve surface extends upwardly and transitions into at least the third sleeve surface at a position maximally removed from the bristle mounting surface of the handle when the sleeve is positioned on the handle. In this aspect of the invention, the first and second sleeve surfaces each preferably include apertures for fitting over exteriorly facing raised portions formed on the first and second surfaces of the handle for retaining the sleeve in position complementally fitting over the handle with the fourth sleeve surface including a plurality of sacrificial cleaning protrusions formed thereon, preferably substantially equally spaced from one another along the fourth surface. In this aspect of the invention, the sleeve is preferably sized and shaped for complemental facing contact fitting over the gripping portion of the handle of the brush.
Cleaning suede is difficult since suedes do not tolerate water. Commonly used methods for cleaning suede leather involve use of petroleum-based solvents in a type of dry-cleaning process. Spot removal may be accomplished using a chlorinated hydrocarbon, often applied in the form of a spray. The problem of cleaning suede, without adversely affecting it, has been recognized for a long time. Thus, there is a long felt, yet unfulfilled need for a simple, easy and safe way to clean suede, or any napped material. This invention fulfills this need by providing a brush for cleaning a textured surface, such as a grain or suede leather surface, even a heavily soiled surface. The area to be cleaned is initially rubbed, wiped, or scraped using protrusions 46 extending from the brush; resulting debris is thereafter brushed away using bristles 32.
Brushes are configured to prevent slippage of the brush from the hand during the cleaning process. Slippage may result in non-uniform cleansing of suede, or other napped material, and possibly result in a noticeable or undesirable non-smooth finish on the underlying suede or other napped material. In the invention this slippage is prevented by having a handle designed generally in a shark-tooth configuration having a shark-tooth gripping portion extending oppositely of the bristle mounting surface 12. The shark-tooth gripping portion is configured to have sloping surfaces facing outwardly from the bristle mounting surface 12 and short surfaces extending generally perpendicular to the bristle mounting surface of the brush. Thus, the gripping portion may be, in effect, clamped between the index finger and thumb thereby preventing slippage of the brush from the grip, while the brush is at the same time contoured to fit comfortably into the user's hand.
The invention further relates to a brush configured to have a gripping surface with a depression or concave portion facilitating grasp of the brush. When the brush is held with the depression or concave portion the brush provides superior holding comfort and ease-of-use.
The various objects and advantages of the present invention are more readily understood from the following detailed description when read in conjunction with the appended drawings.
Referring to the drawings in general and to
Third surface 22 joins each of the two first and second parallel surfaces 18, 20 as shown in
Parallel spaced first and second surfaces 18, 20 each preferably include generally centrally positioned exteriorly facing surface portions which are raised from the areas therearound with such raised central surface portions being denoted 26. Within raised central surface portions 26 are formed areas of depression or concavity with such areas denoted 28 in the drawings. Areas 28 of depression or concavity facilitate manual gripping of the brush between fingers.
Fourth surface 24 further preferably includes a plurality of preferably transversely extending protrusions 30 formed thereon, with protrusions 30 preferably being substantially equally spaced from one another along fourth surface 24 from annular collar 14 to the location of transition of fourth surface 24 into third surface 22.
Brush 10 further includes a plurality of bristles 32 which are preferably embedded in and in any event are mounted on bristle mounting surface 12 and extend outwardly away therefrom, preferably transversely to bristle mounting surface 12. In one aspect of the invention the ends of bristles 32 are frayed, leading to less abrasive bristle surfaces, thereby reducing the likelihood of scratching the surface to be cleaned. However, the invention embracing bristles 32 being more rigid in versions of one brush designed for heavier duty cleaning.
A bristle mounting surface 12 of the brush 10 holds multiple bristles 32. In the one aspect, bristles 32 are arranged in the bristle mounting surface 12 to form a substantially flat bristle surface. In yet another aspect of the invention a curved bristle surface is provided wherein the bristle ends form a wave-like configuration, as shown in
The brush according to the invention may be made from any materials commonly used in the art. The bristles 32 may be made from a flexible material suitable for use on suede or other napped material. Generally, materials suitable for bristles 32 include, but are not limited to, polyamides such as nylon or polyesters such as polybutylene terephthalate. The diameter of the brush bristles is preferably about 0.15 mm to about 0.35 mm.
Brush 10 preferably further includes a hollow removable erasing sleeve 34 which is preferably highly flexible and fabricated of rubber. The rubber of brush 10 can be thermoplastic elastomers (TPE). As used herein TPE denotes any of a family of polymers that resemble elastomers in that they are highly resilient and can be repeatedly stretched to at least twice their initial lengths with full rapid recovery, but are true thermoplastics and thus do not require curing or vulcanization. Thermoplastic elastomers utilize physical cross-links, contrary to conventional vulcanized rubber having a stable three dimensional structure, in which a polymer and a vulcanizer form a covalent bond. The physical cross-links enable thermoplastic elastomers to be easily molded by the same fusion heating process as is applied to conventional thermoplastic resins. Therefore, it is not necessary that the thermoplastic elastomers employ a complicated vulcanizing and molding process including preforming.
Sleeve 34 is preferably configured with four surfaces designated 36, 38, 40 and 42 in the drawings, which substantially match the four surfaces 18, 20, 22 and 24 of gripping portion 16 of handle or body portion 11. First, second, third and fourth surfaces 36, 38, 40, 42 of sleeve 34 preferably complementally contact annular collar 14. First and second surfaces 36, 38 of sleeve 34 are preferably parallel with one another and spaced from one another in the same manner as first and second surfaces 18, 20 of gripping portion 16 of handle or body portion 11 of brush 10. First and second surfaces 36, 38 of sleeve 34 preferably include apertures 44 which are sized for complemental fitting about raised central facing surface portions 26 of parallel spaced first and second surfaces 18, 20 of gripping portion 16.
Fourth surface 42 of sleeve 34 preferably includes a plurality of preferably transversely extending sacrificial protrusions 46 formed on the exterior thereof. Protrusions 46 are at least substantially equally spaced from one another along fourth surface 42 of sleeve 34 in the vicinity of juncture of fourth surface 42 with annular collar 14 when sleeve 34 is positioned on handle or body portion 11, so that sacrificial protrusions 46 may make erasing contact with the suede shoe surface or other suede surface to be cleaned.
The operation of the shoe brush 10 combines the properties of the eraser sleeve 34 with the brush effect of the bristles 32. Specifically, a mark or stain on the suede material, or other napped material, is erased using the, eraser sleeve 34 while attached to the handle or body portion 11. Alternatively, the sleeve may be removed from the body portion 11 so as to allow placement of the index, or other, finger into the inside concave contour of the sleeve located just behind the area having sacrificial protrusions 46, thereby allowing a greater control over the amount of and pressure of the applied force. Thereafter, the shavings of the eraser sleeve 34 and particles of the suede material, or other napped material, including the stain or mark, are brushed away by bristles 32.
Brush 32 may be fabricated from, for example without limiting the invention, polymeric materials, namely fairly high strength engineering polymers such as polycarbonate, acrylonitrile butadiene styrene, and fiber reinforced composites. Polymer material, such as a block co-polymer including, but not limited to, styrenes (for example styrene-ethylene-butadiene-styrene, or styrene-butadiene-styrene), polyolefins (for example polypropylene/ethylene propylene), diamine modified systems (for example synthetic rubber), polyamides (for example polyamide 2 or polyamide 6), polyesters (for example polyester ester or polyether ester), polyurethanes (for example polyesterurethane, polyetherurethane or polyesteretherurethane) are also contemplated. In alternative aspects of the invention the brush can be molded from polyolefins such as polypropylenes and polyethylenes, polyamides such as nylons, and polyesters such as polyethylene terephthalate. Other suitable materials include polymethylmethacrylate, styrene acrylonitrate and cellulose esters, for example cellulose propionate.
It is to be understood that the brush assembly of the present invention may be manufactured in configurations other than those shown herein. All of such modifications and variations are within the scope of the present invention, and in view of the disclosure herein numerous other modifications and variations may be implemented by one of skill in the art. The foregoing drawings, discussion and description are illustrative of particular embodiments of the invention and are not meant to be limitations upon the practice thereof. It is the following claims, including all equivalents, which define the scope of the invention.
