  • Cleaning pad 28 is generally known in the art and comprised of a combination of fibers defining a cleaning surface 60 and attachment portion 62.
  • Cleaning pad 28 may be comprised from a single cleaning pad or from multiple cleaning pads attached sequentially to cover the cleaning pad support member 26.
  • the cleaning pad 28 may, for example, include a plurality of fluffed nonwoven fabrics made of synthetic resins, which may be welded to one another.
  • the pad may include fibers constructed from PP, PE, PET fibers in a variety of alternative percentages by weight
  • attachment portion 62 defines a pocket or sleeve 64 configured to tightly fit over support member 26.
  • Attachment portion 62 may be constructed from an elastic material to snuggly fit over the support member 26.
  • sleeve 64 is illustrated as having an open end 51 and a closed end 52, it should be recognized that the sleeve 64 could have two open ends to allow the cleaning pad 28 to be reversible and insertable on the support member 26 from either end.
  • the reversibility of the cleaning pad 28 allows for maximum use of the cleaning pad 28. As it has been shown that during dusting the tip of the cleaning pad 28 furthest from the handle 24 accumulates the most dust, the reversibility of the cleaning pad 28 allows for maximum usage of the cleaning surface 60 of the cleaning pad 28.
  • the cleaning pad 28 includes an elastic attachment portion 62.
  • Velcro® or rubber bands could be included on a segment of the attachment portion 62 in order to retain the cleaning pad on the cleaning pad support member 26.
  • Other support structures or retaining features may also be used to retain the cleaning pad 28 on the support member 26.
  • Cleaning pad 28 is preferably, a 20g/sqm spun lace cloth with between 1-4% mineral oil manufactured by Haso Corporation of Japan. Examples of such cleaning or dusting pads are described in PCT/JP2004/010507 .
  • the cleaning surface 60 of cleaning pad 28 may be comprised of a polymer that allows for the spontaneous transport of aqueous fluids.
  • a polymer that allows for the spontaneous transport of aqueous fluids.
  • Such polymers are described in, for example, U.S. Patent Nos. 5,723,159 , 5,972,505 and 5,200,248 .
  • the polymer fibers of the cleaning pad can take a variety of forms to increase various performance characteristics of the cleaning system 20.
  • Standard circular fibers may be used, as is generally known in the art.
  • the individual fibers on the cleaning pad 28 may be lobed in the form of loose tow fibers.
  • the unique lobed configuration creates channels within the individual fibers enabling improved capillary action on each individual fiber and increasing the overall cleaning or dusting surface area and thereby increasing the overall efficiency of both wet and dry dusting. Higher surface area also results in an increase in the proportion of particles adhering in the grooves or channels and results in dust particles being "trapped" within the grooves of the lobed fiber.
  • the lobed fibers not only generally exhibit improved dust retention, but also more efficient wet wiping characteristics and longer life than standard circular fibers. Furthermore, the lobed fibers can be made stiffer thereby generating a higher wiping pressure in a smaller contact area. It is understood that the inventive lobed fibers could be comprised of a multitude of polymers with PP, PE or PET being recognized as the most cost effective alternatives. Alternatively, acrylic or biodegradable polymers may also be utilized.
  • the cleaning pad 28 may include stiffer or strut fibers attached to mass of tow fibers.
  • the stiffer fibers (usually in the range of about 0.3mm) carry the majority of the stress applied to the cleaning pad 28.
  • the tow may be linked to the stronger fibers by entanglement at the outer ends of the fiber.
  • the stiffer fibers result in a cleaning pad 28 that is springy resulting in a more desirable feel of applied force for users.
  • the stiffer fibers may further be utilized to clean difficult areas such as crevices, blinds or screens.
  • the stiffer fibers have the further advantage in that they keep the tow volume expanded, thereby increasing dust migration into the tow fibers.
  • the cleaning pad 28 could include absorbent materials in particulate form fixed onto the remaining fibers of the cleaning pad 28.
  • the absorbent materials may take the form of known super absorbent polymers ("SAPs").
  • SAPs may be, for example, acrylic based polymers applied as a coating or turned into fibers directly.
  • Such commercially available SAPs generally include X-linked polyacrylic acids or X-linked starch-acrylic-acid-graft-polymers, the carboxyl groups of which are partially neutralized with sodium hydroxide or caustic potash.
  • SAPs may be made by such processes as a solvent or solution polymerization method or the inverse suspension or emulsion polymerization method.
  • Such SAPs are disclosed in, for example, U.S. Pat. No. 6,124,391 .
  • the above-mentioned absorbent materials increase the overall absorbency of the fibers, prevent the fibers from packing close together into a fiber mass, and enhance the friction of the fibers.
  • the "string of pearls" arrangement also allows for strategically placed high absorbency regions on the cleaning pad. For example, if it is desirable to have the forward end of the cleaning pad 28 be more absorbent than the remainder of the cleaning pad 28, the forward end could include a higher percentage of the particulate absorbent materials.
  • the cleaning pad 28 may also include fibers that are formed into helices. Such fibers may be formed by drawing fiber bundles over a blade or heating coaxial bicomponent fibers. The resulting helical fibers exhibit a fluffier texture and more attractive appearance while at the same time increasing the volume (while using less fiber) and dust retention of the duster.
  • the helical nature of the fibers is also advantageous in that they allow coarse fibers to feel softer due to the spring effect. Furthermore, the fibers gradual loss of the helical nature can serve as an indication of the effective life of the cleaning pad.
  • the cleaning pad 28 may be comprised of three component sheets or layers. Two sheets form the carrier or base and they are attached to a cleaning or wipe-off layer of nonwoven fibers.
  • the two part carrier includes an outermost or top sheet forming the sleeve or pocket 64 configured to receive the flexible cleaning pad support member. Beneath the pocket is a second carrier sheet.
  • the carrier layer includes a plurality of fringes or strips extending along its lateral sides. Underneath the second carrier layer is the wipe-off layer.
  • the wipe-off layer is comprised of tow fiber (loose nonwoven fibers).
  • the tow is preferably a bi-component fiber consisting of a polypropylene core and a polyethylene outer surface.
  • the three component layers may be bonded to each other by a central heat-seal line extending through the center of the three component layers. Along the opposed edges of the pocket layer, are a series of spot welds.
  • a base carrier layer is bonded to the tow fibers via a central weld line and a series of spot welds running along the lateral sides of the cloth. The spot welds only bond the carrier sheet and the tow fiber.
  • Two additional layers are attached to the base carrier layer to form the pocket or sleeve 64. The pocket layers are sealed with continuous heat seal lines extending between the two exterior pocket layers.
  • the tow fiber is also bicomponent, but it consists of a polypropylene core and a polyester outer layer. In another preferred embodiment, polypropylene or nylon fibers are welded to the center of the tow fiber.
  • the cleaning pad could include strategic combinations of the various fibers and other known fibers.
  • the cleaning pad may be comprised of between 25-100% of the lobed fibers by weight.
  • the inventive pad could include multiple cleaning surfaces, with alternate or similar fiber configurations to accommodate various cleaning functions.
  • a cleaning pad 28 could be two sided with one side of the cloth for dusting and the alternate side of the cleaning pad 28 for cleaning. This may also be accomplished by turning the pad "inside out” to expose a new clean surface.
  • a triangular or other multi-sided cleaning pad 28 could be utilized.
  • a variety of cleaning pad 28 shapes or configurations may be utilized to maximize the various properties of the cleaning pad 28 and selected fibers.
  • the orientation and type of fibers utilized on the cleaning pad 28 could include a wide variety of alternatives.
  • the cleaning pad 28 may include a generally fluffy pad including a flat center strip around the area defined by the pockets or sleeves 64. Such an orientation may increase the surface area and exhibit a better efficacy.

  • cleaning pads consisting of alternating sections of sponges, feather-like structures, scrubbing pads, microfibers or cellulose foam. Wood pulp is preferred.
  • the cleaning pad 28 could also include a fluffy cloth with a hydrophilic additive to improve the absorbency of water.
  • hydrophilic additives include but are not limited to glycerin and glycols.
  • the cleaning pad 28 could also be comprised entirely of an absorbent material such as Rayon.
  • the cleaning pad 28 or cleaning pad support member 26 could also include a piezoelectric crystal to impart an electrostatic charge on the cleaning pad during use to increase dust retention.
  • Such crystals are generally known and typically generate a charge when subjected to mechanical stress.
  • materials that can be used include but are not limited to quartz analogue crystals like berlinite (AlPO 4 ) and gallium orthophosphate (GaPO 4 ), ceramics with perovskite or tungsten-bronze structures (BaTiO 3 , KNbO 3 , LiNbO 3 , LiTaO 3 , BiFeO 3 , Na x WO 3 , Ba 2 NaNb 5 O 5 , Pb 2 KNb 5 O 15 ).

These engagement or retaining features create at least 2.51bf of pivot force.
  • a user may manipulate the cleaning system 220, 320, 520 via the handle portion 224 as well as adjust the flexible cleaning pad support member 226, 326, 526. Additionally, the user may apply the water or other liquid housed within the fluid reservoir 233 directly onto the surface to be cleaned.
  • the user may insert a finger through the opening 237 and depress the spray cap thereby causing the discharge of the fluid housed within the reservoir 233, Due to the orientation of the cleaning system 220, 320, 520 in the cleaning position, the liquid will typically be applied directly to the surface to be cleaned in an area behind the cleaning pad 228, 328, 528 when the system is in a horizontal orientation such as when dusting a coffee table. Alternatively, a cleaning solution can be sprayed onto a vertical surface to be cleaned, such as a window or door molding.
  • FIGS. 7 and 8 illustrate (in phantom) the cleaning system 220 in a second liquid application position. It should be understood that cleaning system 520 can occupy the same position.
  • the cleaning pad support member 226, 526 into the liquid application position a user must hold the handle portion 224 and apply torque to the cleaning pad support member 226, 526 to move it from the cleaning position illustrated.
  • the circular pivot member rotates downwardly into the liquid application position.
  • pivot engagement tab 241 engages the liquid application notch of the pivot member thereby holding the cleaning pad support member 226, 326, 526 is its angled liquid application state.
  • the angle between the cleaning pad support member 226, 326, 526 and the handle portion 224 in the liquid application position may be between 45° and 68°.
  • the angle between the cleaning pad support member 226, 326, 526 and the handle portion 224 is between 55° and 68° with 63° being particularly preferred. This preferred angle takes into consideration the spray pattern of the fluid reservoir in order to achieve liquid application onto the greatest surface area of the cleaning surface of the cleaning pad 228, 328, 528.
  • a user may repeatedly rotate the cleaning pad support member 226, 326, 526 from its cleaning position to its liquid application position as needed.
  • a user may simply apply liquid directly to the surface to be cleaned while using the cleaning system 220, 320, 520 in the cleaning position.
  • the cleaning system 220, 320, 520 also includes a storage position.
  • the storage position the cleaning pad support member 226, 326, 526 is rotated backwards such that it is generally parallel to the plane defined by the longitudinal axis of the handle portion 224.
  • engagement tab 241. engages the storage position notch thereby maintaining cleaning pad support member 226 in its folded position.
  • the cleaning system 220, 320, 520 may be easily stored into a variety of spaces such as kitchen drawers or cabinets. Alternatively, the system can be hung on a wall using the opening 232 in the handle portion 224.
  • the described cleaning systems 22, 222, 322, 522 and methods of use provide multiple benefits versus conventional cleaning modes. It reduces time to clean or dust, because the cleaning pad retains a greater amount of dust and the preferred cleaning solution removes fingerprints smudges and other surface marks. Additionally, since a fresh pad may be used every time, germs and dirt are trapped, removed and thrown away, promoting better hygiene. Conventional dusting tools, which are re-usable, can harbor dirt and germs, which can be spread throughout the household.
  • the cleaning pads are versatile in that they can be used for multiple cleanings and multiple surfaces. Each pad is designed to clean at least one average size surface with an average debris or dust load. Pads can be changed sooner if surfaces are larger than average, or especially dirty. To determine if the pad needs changing, visual inspection of the back of the cleaning surface of the cleaning pad will confirm if the cleaning surface is saturated with dust and/or dirt.
  • a kit can be provided that has multiple cleaning pads and solutions for different cleaning tasks.
  • One solution and cleaning pad could be used for surface cleaning and another solution and pad for dusting.
  • the solution bottles and pads may be color coordinated by use.
  • the kit may be sold separately with advertising and instructions in each kit being used to explain the benefits of using the various products together.
  • inventive systems 20, 220, 320, 520 described above may be manufactured and sold separately or together in the form of a cleaning system or kit. It should be further understood the present invention contemplates a variety of additional alternative configurations and component parts which may be attached to the cleaning pad support member, A wide variety of alternative interchangeable cleaning implements may be substituted for the cleaning pad support member 25, 226, 326, 526 described above.
  • an alternative cleaning implements could include a squeegee for cleaning windows, mirrors or other glass structures, a soft surface cleaner such as a lint roller, a glass cleaner including an indexing refill roll, an insect swatter, a dog brush or other grooming implement, a scrub brush, sponge, mop, paint brush, toilet brush or other cleaning implement etc.
