DETAILED DESCRIPTION OF THE INVENTION

(12) While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will be described herein in detail, one or more specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated.

(13) It will be understood that like or analogous elements and/or components, referred to herein, may be identified throughout the drawings by like reference characters. In addition, it will be understood that the drawings are merely schematic representations of one or more embodiments of the invention, and some of the components may have been distorted from their actual scale for purposes of pictorial clarity.

(14) Referring now to the drawings, and to FIG. 1 in particular, drain servicing assembly 10 is shown as generally comprising base member 12, inner containment member 14, motor/drill 16, shaft sub-assembly 18, and cover member 20. In accordance with the present invention, drain servicing assembly 10 is configured to provide a user with a clean, sanitary, and efficient way to service any one of a number of drains and associated compromised conditions.

(15) As is best shown in FIG. 2, base member 12 generally includes bottom wall 22, left sidewall 24, right sidewall 26, and rear sidewall 28. In certain embodiments, base member 12 may include handle 30 which optionally includes axle 32 for retaining a pair of free spinning wheels (See FIG. 9). Base member 12 may also include axle 34 for retaining an additional pair of free spinning wheels (See FIG. 9).

(16) Base member 12 is preferably fabricated from, for example, metals (e.g. aluminum, tin, copper, nickel, titanium, steel, and alloys thereof), natural resins, synthetic resins, plastics, composites, woods, and mixtures thereof. In one embodiment, base member 12 is at least partially coated (e.g., dip coated, spin coated, brush coated and/or spray coated—including, but not limited to, cold spraying, thermal spraying, high velocity spraying (e.g., supersonic), low velocity spraying (e.g., subsonic), triboelectric discharge kinetic spraying and other similar processes) with at least one overcoat material selected from the group consisting of a natural polyisoprene, a synthetic polyisoprene, a polybutadiene, a chloroprene rubber, a butyl rubber, a halogenated butyl rubber, a styrene-butadiene rubber, a nitrile rubber, a hydrogenated nitrile rubber, an ethylene propylene rubber, an ethylene propylene diene rubber, an epichlorohydrin rubber, a polyacrylic rubber, a silicone rubber, a fluorosilicone rubber, a fluoroelastomer, a perfluoroelastomer, a polyether block amide, a chlorosulfonated, ethylene-vinyl acetate, a resilin, an elastin, a polysulfide rubber, an elastolefin, and combinations thereof.

(17) In accordance with the present invention, base member 12 may be associated with one or more anti-microbial, anti-bacterial, and/or anti-viral agents.

(18) Suitable anti-microbial agents comprise chemical compositions that at least substantially inhibit microbial growth and/or kill bacteria, fungi and/or other microorganisms. A plurality of inorganic and/or organic chemical compositions which display anti-microbial activity are suitable for use with the present invention. Non-limiting examples of suitable organic substances that possess anti-microbial activity are carboxylic acids, alcohols and/or aldehydes, most of which appear to act by protein precipitation and/or by disruption of microbial cell membrane.

(19) In one embodiment of the present invention, the anti-microbial activity of suitable inorganic substances is generally related to the ions, toxic to other microorganisms, into which they dissociate. The anti-microbial activity of various metal ions, for example, is often attributed to their affinity for protein material and the insolubility of the metal proteinate formed. Metal-containing salts are thus preferred among the inorganic substances that act as anti-microbial agents.

(20) Metal inorganic salts, including simple salts of metal cations and inorganic anions like silver nitrate, are often soluble and dissociable and, hence, offer ready availability of potentially toxic ions.

(21) Metal salts or complexes of organic moieties such as organic acids, on the other hand, are often less soluble and, therefore, are less dissociable than the soluble metal inorganic salts. Metal organic salts or complexes generally have a greater stability with respect to extraneous organic matter, and anions present in the environment of the living cell than metal inorganic salts, but have less toxic potential by virtue of their greater stability.

(22) Silver ion is an example of a preferred metal ion which possess anti-microbial activity. To the best of Applicant's knowledge silver ions react with a variety of anions as well as with chemical moieties of proteins. Precipitation of proteins, causing disruption of the microbial cell membrane and complexation with DNA, is likely the basis of the anti-microbial activity. Silver ions in high concentration will form insoluble silver chloride and thereby deplete chloride ions in vivo.

(23) Anti-bacterial agents are preferably antiseptics that have the proven ability to act against bacteria. Non-limiting examples of anti-bacterials suitable for use in accordance with the present invention include alcohols such as ethanol (20-99.sup.+%), 1-propanol (20-99.sup.+%) and 2-propanol/isopropanol (20-99.sup.+%) or mixtures of these alcohols. They are commonly referred to as “surgical alcohol”. Used to disinfect an area, often along with iodine (tincture of iodine) or some cationic surfactants (benzalkonium chloride 0.05-0.5%, chlorhexidine 0.2-4.0% or octenidine dihydrochloride 0.1-2.0%). Other common anti-bacterials include quaternary ammonium compounds known as Quats or QAC's, include the chemicals benzalkonium chloride (BAC), cetyl trimethylammonium bromide (CTMB), cetylpyridinium chloride (Cetrim, CPC) and benzethonium chloride (BZT). Benzalkonium chloride is used in some pre-operative skin disinfectants (conc. 0.05-0.5%) and antiseptic towels. The anti-microbial activity of Quats is inactivated by anionic surfactants, such as soaps. Related disinfectants include chlorhexidine and octenidine.

(24) It will be understood that base member 12 and/or any other component of drain servicing assembly 10, including any overcoat layer, may be single or double sidedly dip or spray coated with the anti-microbial, anti-bacterial, and/or anti-viral agents, or alternatively the components may be impregnated with one or more of the aforementioned agents.

(25) Referring now to FIG. 3, inner containment member 14 generally includes rear wall 36, substantially circular inner sidewall 38, and substantially circular outer sidewall 40, and lip/flange 42. Inner containment member 14 may include slot/aperture 44 (See FIGS. 4 and 5) which is adapted to accommodate a portion of the shaft sub-assembly. Inner containment member 14 is secured to base member 12 via conventional fasteners, and freely rotatable proximate a centralized axis.

(26) Inner containment member 14 is preferably fabricated from, for example, metals (e.g. aluminum, tin, copper, nickel, titanium, steel, and alloys thereof), natural resins, synthetic resins, plastics, composites, woods, and mixtures thereof. Inner containment member 14 may also be associated with one or more overcoat materials and/or one or more anti-microbial, anti-bacterial, and/or anti-viral agents as disclosed supra.

(27) Referring now to FIGS. 4 and 5, motor 16 (FIG. 4) and/or drill 16 are preferably secured to sidewall 36 of inner containment member 14. As will be discussed in greater detail below, motor/drill 16 variably and rotatably actuates the flexible inner shaft of shaft sub-assembly 18 without rotatably actuating the outer sheath of shaft sub-assembly 18. In accordance with the present invention, motor/drill 16 may be AC and/or DC powered and are commercially available at conventional hardware and electrical supply stores.

(28) Referring now to FIGS. 6 and 7, shaft sub-assembly 18 generally includes outer sheath 46 and inner shaft 48. Inner shaft 48 is preferably rotatable independently of outer sheath 46. On a first end, inner shaft 48 is releasably coupled to and in mechanical communication with the motor/drill 16, and on a second end, inner shaft 48 is releasably coupled to and in mechanical communication with a cutting head, a functional head, a painting head, a camera, etcetera. Outer sheath 46 and inner shaft 48 are both preferably sufficiently flexible to be wound into inner containment member 14, as well as displaced throughout conventional household supply lines, drains, plumbing, etcetera.

(29) Outer sheath 46 and inner shaft 48 are both preferably fabricated from, for example, metals (e.g. aluminum, tin, copper, nickel, titanium, steel, and alloys thereof), natural resins, synthetic resins, plastics, composites, woods, and mixtures thereof. Outer sheath 46 and/or inner shaft 48 may also be associated with one or more overcoat materials and/or one or more anti-microbial, anti-bacterial, and/or anti-viral agents as disclosed supra.

(30) Referring now to FIG. 8, cover member 20 generally includes top wall 50 and front sidewall 52. It will be understood that base member 12 and cover member 20 cooperatively form an enclosure having a containment region therein for containing inner containment member 14, motor/drill 16, and shaft sub-assembly 18. Cover member 20 also preferably includes guide member 54. Guide member 54 facilitates the extraction and/or retraction of shaft sub-assembly 18 by a user.

(31) Cover member 20 and guide member 54 are preferably fabricated from, for example, metals (e.g. aluminum, tin, copper, nickel, titanium, steel, and alloys thereof), natural resins, synthetic resins, plastics, composites, woods, and mixtures thereof. Cover member 20 and guide member 54 may also be associated with one or more overcoat materials and/or one or more anti-microbial, anti-bacterial, and/or anti-viral agents as disclosed supra.

(32) In operation a user deploys drain servicing assembly 10 to a location with, for example, a clogged drain. Shaft sub-assembly 18 is fitted with a cutting head, a functional head, a painting head, and/or a camera—depending on the situation. Shaft sub-assembly 18 is pulled out of inner containment member 14 via rotational displacement in a controlled manner in cooperation with guide member 54. The user may then actuate, for example, a cutting head remotely with motor/drill 16 to resolve the problem/situation without spraying any portion of the location with debris from the shaft. Once the problem/situation is resolved, shaft sub-assembly 18 can be washed by a user and quickly retracted into inner containment member 14.

(33) The foregoing description merely explains and illustrates the invention and the invention is not limited thereto except insofar as the appended claims are so limited, as those skilled in the art who have the disclosure before them will be able to make modifications without departing the scope of the invention.
