BACKGROUND OF THE INVENTION
1. Cross-Reference to Related Application
2. Field of the Invention
[0002] The present invention relates to the field of cleaning devices such as hand held
dusters and dust mops, bathroom cleaners, toilet cleaners and other cleaning devices.
More particularly, the present invention relates to a flexible cleaning device for
accommodating the cleaning or dusting of difficult to access surfaces having a handle
defining a cradle for receiving a fluid reservoir attached to a support arm for mounting
a cleaning implement. The entire system is capable of either wet, damp or dry dusting
or cleaning.
3. Discussion of the Related Art
[0003] For decades, hand held feather dusters, dust rags and other cleaning implements have
been used as cleaning tools for the removal of dust adhering to furniture such as
dressers and coffee tables, electrical appliances such as computers, lights, interior
walls, lintels and the like. Thus, it is generally well known to remove dust or dirt
from floors, furniture, and other household surfaces by rubbing a dust rag, cloth
or other cleaning implement against the surface to be cleaned such that the dust or
dirt adheres to the cleaning implement.
[0004] Despite the existence of numerous dusting or cleaning implements, dusting or cleaning
of surfaces in hard to reach and inaccessible areas remains a common problem. Currently,
in order to clean behind a heavy appliance such as a television or stereo, a user
must physically move the appliance to enable the user to adequately clean behind it.
Certain fixtures, such as radiators and base board heaters in older homes are immovable
and present a significant challenge for cleaning. Likewise, other odd shaped or difficult
to reach surfaces such as the inner rim of a toilet seat or the spindle on a staircase
provide challenges to cleaning.
[0005] While hand held dusters and other cleaning implements are generally well known in
the art, numerous drawbacks exist with the current commercially available designs.
For example, U.S. Application Pub. No.
US 2004/0034956 A1,
U.S. Patent No. 6,813,801,
U.S. Patent No. 5,953,784 and
U.S. Patent No. 6,550,092, disclose variations of hand held cleaning devices incorporating a disposable cleaning
pad. These devices, while somewhat suitable for the desired application, exhibit notable
limitations. For example, none of the above-cited references provide an elongated
flexible support arm that allows a user to bend the duster or cleaning device into
a variety of shapes. Instead, most prior art hand held dusters or cleaners utilize
rigid supports that do not allow a user to shape the duster into unique configurations
to enable the user to dust or clean behind hard to reach places. While some prior
art devices exhibit a movable joint to enable better storage or shipping, such devices
are typically constructed to be flexible only in the one direction, and as such its
cleaning capability is restricted by its maneuverability. The duster of the present
invention overcomes the disadvantages of the prior art since, inter alia, it is constructed
of an elongated rod which is flexible in all directions.
[0006] In general, the majority of improvements to hand held dusters and cleaners have been
directed at improving the basic mechanical components of the cleaning device. These
improvements have been directed at providing an inexpensive yet robust implement for
dry dusting or cleaning. However, notably absent in the prior art is any attempt to
provide a hand held cleaning implement that allows for rotational movement to allow
for a flexible cleaning device.
[0007] Likewise, the cleaning surface of the cleaning implement in many of these devices
is relatively small, such that use of these cleaning devices on large surfaces requires
considerable effort on the user's part. In addition, most prior art cleaning pads,
only include a single cleaning surface. The duster of the present invention overcomes
the disadvantages of the prior art since, inter alia, it is constructed of an elongated
360° cleaning surface.
[0008] In addition there are no known prior art hand held cleaning implements that allow
for selective wet, damp or dry dusting. The addition of water or other cleaning solution
to most cleaning pads or systems has been known to increase the efficiency of the
cleaning device in absorbing dust and other debris. Despite this knowledge, there
are presently no known hand held cleaning systems, with flexible support members that
include an attached water or cleaning fluid reservoir accessible on the cleaning implement
to allow a user to single handedly alternate between wet, damp or dry dusting. To
date, prior art dusting and cleaning devices require a user to obtain a separate spray
bottle or other liquid application means if one desires wet dusting or cleaning.

DESCRIPTION OF PREFERRED EMBODIMENTS
[0030] The present invention and the various features and advantageous details thereof are
explained more fully with reference to the non-limiting embodiments described in detail
in the following description.
1. System Overview
[0031] In a basic form, the invention is a cleaning system that includes a handle, cleaning
pad or duster, and a flexible cleaning pad support capable of supporting a cleaning
pad or other cleaning implement. The cleaning system allows a user to dust in a variety
of different places because the flexible cleaning pad support can be formed into a
variety of shapes. Despite its flexibility, the support maintains its shape. A 360°
cloth allows the system to be used to clean multiple surfaces at once. In additional
embodiments, the cleaning system is designed for use in wet, damp or dry cleaning
and includes a fluid reservoir or liquid delivery system and the cleaning pad support
is moveable via a pivotable connection to the handle portion. The cleaning system
allows for fluid application directly to a cleaning pad or to a surface to be cleaned.
This results in a single hand operated tool that provides options for wet, damp or
dry cleaning not available in traditional cleaning devices.
2. Detailed Description of Preferred Embodiments
[0032] Specific embodiments of the present invention will now be further described by the
following, non-limiting examples which will serve to illustrate various features of
significance. The examples are intended merely to facilitate an understanding of ways
in which the present invention may be practiced and to further enable those of skill
in the art to practice the present invention. Accordingly, the below examples should
not be construed as limiting the scope of the present invention.
[0033] Turning initially to FIGS. 1 and 2, the inventive cleaning system 20 is illustrated
according to one preferred embodiment of the present invention. Cleaning system 20
is generally comprised of a cleaning device or tool 22, including a handle portion
or handle 24 and attached flexible cleaning pad support, flexible support rod or flexible
support member 26, and a cleaning pad or cleaning implement 28 attached to the cleaning
tool 22 via the cleaning pad support member 26.
[0034] Handle portion 24 is preferably an ergonomically designed member configured to comfortably
fit within the palm of a hand of a user. Handle portion 24 includes an integral forward
cleaning pad support member connection surface 29, bottom 31, and ergonomic side 32.
Handle portion 24 may be constructed from a variety of synthetic resins, plastics
or other suitable materials. In the preferred embodiment, handle portion 24 includes
a soft cover 34 for comfortable use by a user. The cover 34 may be made from foam,
rubber or other known soft materials. Although the handle portion 24 may be constructed
in a wide variety of sizes depending on the intended use, in the preferred embodiment,
handle portion 24 is approximately 5.2 inches or 13.21 mm. long. The preferred dimensions
allows for ease of use, manipulation, packaging, shipping and storage of the cleaning
system 20 as well as increasing the overall ergonomics of the design. Handle portion
24 may be constructed in a variety of colors for increased aesthetic appeal. It may
additionally be constructed from a translucent material. The handle portion 24 could
also house an extension element for added reach or allow for the connection of an
extension element.
[0035] Attached to the handle portion 24 is the flexible cleaning pad support member 26.
The flexible cleaning pad support member 26 may be attached to the handle portion
24 in a variety of conventional ways. The elongated flexible cleaning pad support
member 26 is capable of being manually moved into a plurality of differing shapes
while at the same time exhibiting enough strength to maintain its position during
dusting or cleaning. As illustrated by Figs. 5 and 6, such shapes include bending
the flexible cleaning pad support member 26 to form a 90° angle, or wrapping a portion
of the flexible cleaning pad support member 26 around a spindle or rod. A wide variety
of other configurations may also be formed. The cleaning pad can be inserted from
either end, enabling the user to make get the most utility out of the pad, since the
portion furthest from the user often gets dirtiest fastest.
[0036] In the illustrated preferred embodiment of FIGS. 2 and 4, the elongated flexible
cleaning pad support member 26 has a retaining means of the type marketed by Lockwood
Products, Inc. under the trade designation LOC-LINE®. This product is typically used
as a modular hose system for providing high volume fluids.
[0037] The elongated flexible cleaning pad support member 26 comprises a plurality of interconnected
segments 40. Although the cleaning pad support member may be constructed in a wide
variety of sizes depending on the intended use, in the preferred embodiment the elongated
flexible cleaning pad support member 26 is approximately 12.5 inches, or 31.75mm.
long.
[0038] As illustrated in FIG. 2 and 4, each segment 40 preferably comprises a central body
portion 42, a male end portion 44 and a female end portion 46. The male end portion
44 has an outer surface 48 comprising a frustum of a sphere and the female end portion
46 has a mating inner surface 50 comprising a frustum of a sphere which is dimensioned
so that, when the male end portion 44 is inserted into the female end portion 46,
there is frictional contact between the mating male end portion outer surface 48 and
female end portion inner surface 50. These frictional forces function as retaining
means to hold one segment 40 at any desired location relative to an interconnected
segment 40. However, these frictional forces can be overcome, and thus permitting
interconnected segments 40 to be moved relative to each other so that their longitudinal
axes are either in or out of alignment. This permits unrestricted relative rotational
movement therebetween. Thus, the static friction holds the segments in place and is
overcome when a user initially starts moving the segments. Once in motion, low dynamic
friction that makes the segments 40 easy to move. This connection permits the attached
cleaning pad 28 to have the same relative movements as the interconnected segments,
as described above. The length of the elongated flexible cleaning pad support member
26 can be changed by adding or removing segments 40.
[0039] In one embodiment, the interconnected segments 40, closest the handle portion (e.g.
extending about 6 inches, or 15.24mm. from the handle portion) are stiffer than the
remaining interconnected segments 40. This allows the tool to better hold its shape
when used especially on flat surfaces. Otherwise the handle becomes perpendicular
to the work surface, as opposed to a preferred use angle. In order to ensure such
an effect, the first six inches or 15.24mm of the segments 40 may be encased, for
example, in rubber heat shrink tubing.
[0040] At the end of the flexible cleaning pad support member 26 is a cone shaped end member
52. Cone shaped end member 52 includes a pointed tip 53 a central body portion 54,
and a female end portion 56 configured to receive the male end portion 44 of a segment
40. The pointed tip 53 may include an aperture therein for the discharge of a cleaning
solution in one embodiment of the design. As it can be appreciated from the attached
figures, the entire design of the flexible support member 26 provides an exterior
surface that makes it easy to slide the cleaning media over the cleaning support member
26 onto the cleaning tool 22. Likewise, due to the outer edge of the female end portions
46, the cloth is retained onto the cleaning pad support 26 during dusting.
[0041] Although not shown, it should be recognized that handle portion 24 and flexible cleaning
pad support member 26 may define a fluid delivery passage. The handle portion 24 could
house a liquid that could be selectively discharged from the flexible cleaning pad
support member using a variety of known means. The fluid may be comprised of a variety
of known products. Preferably the fluid is selected from the commercially available
Pledge® Multi-Surface Cleaner, Pledge® Wood and Glass Cleaner, End Dust®, Fantastic®
all purpose cleaner, Windex® glass cleaner, anti-bacterials such as Oust® or Lysol®,
fragrances such as Glade®, leather or vinyl treatment such as Armor All®, fabric protectors
such as Scotch Guard®, or fabric fresheners such as those manufactured by S.C. Johnson
& Son, Inc. of Racine, Wisconsin, or Febreze®. The fluid may alternatively generally
comprise, without limitation: any all-purpose cleaner, oil or water based dust inhibitor,
anti-static, anti-microbial, antibacterial, sanitizing and de-odorizing agent, dusting
agent, glass cleaner, furniture polish, leather or vinyl treatment, other cleaning
agent, wax, polish or shining agent, softening agent, friction-enhancing compound,
perfumes, dish cleaner, soap, insect repellent or insect barrier, exfoliator or other
personal care product, paint for sponge painting or other application, water out emulsions,
oil out emulsions, dust mite killer or repellant, abrasive cleaner, shoe polish, pet
sanitation products, etc.
[0042] 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 In the illustrated embodiment, 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. Although in the illustrated embodiment, 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.
[0043] In the illustrated preferred embodiment, the cleaning pad 28 includes an elastic
attachment portion 62. However, it is recognized that alternative configurations could
be utilized to effectively retain the cleaning pad 28 on the support member 26. For
example, 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.
[0044] 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.
[0045] The cleaning surface 60 of cleaning pad 28 may be comprised of 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.
[0046] It should be recognized that 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. Alternatively,
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.
[0047] In another alternative embodiment, the cleaning pad 28 may include stiffer or strut
fibers attached to mass of tow fibers. In this arrangement, 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.
[0048] In yet another alternative embodiment, 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").
The 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. The 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.
[0049] 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. In one embodiment, 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.
[0050] 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.
[0051] In one embodiment, 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.
[0052] In another embodiment, 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.
[0053] It should be recognized that none of the aforementioned fiber materials or configurations
are exclusive. The cleaning pad could include strategic combinations of the various
fibers and other known fibers. In one example, the cleaning pad may be comprised of
between 25-100% of the lobed fibers by weight.
[0054] Similarly, although the preferred embodiment discloses a 360° uniform cleaning surface
60, the invention is in no way limited to such a single cleaning surface. To the contrary,
numerous alternative configurations are within the scope of the present invention.
For example, the inventive pad could include multiple cleaning surfaces, with alternate
or similar fiber configurations to accommodate various cleaning functions. In one
embodiment, 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. Alternatively, a triangular
or other multi-sided cleaning pad 28 could be utilized. In general, 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.
[0055] As noted above, the orientation and type of fibers utilized on the cleaning pad 28
could include a wide variety of alternatives. For example and in no way limiting,
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. Additionally, the center strip could
include an absorbent pillow or tube extending down the center of the cleaning pad
28. Such an absorbent pillow could provide an area of high absorbency on the cleaning
pad 28. Various alternative combinations are envisioned including, for example, cleaning
pads consisting of alternating sections of sponges, feather-like structures, scrubbing
pads, microfibers or cellulose foam. Wood pulp is preferred.
[0056] The cleaning pad 28 could also include a fluffy cloth with a hydrophilic additive
to improve the absorbency of water. Such 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.
[0057] 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. Examples of 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
xWO
3, Ba
2NaNb
5O
5, Pb
2KNb
5O
15). Additionally some Polymer materials like rubber, wool, hair, wood fiber, and silk
exhibit piezoelectricity to some extent and may be utilized. Additionally, the polymer
polyvinylidene fluoride, (-CH
2-CF
2-), which exhibits piezoelectricity several times larger than quartz may be used.
[0058] The cleaning pad 28 may also include a portion of an unbonded web material, as described
in
U.S. Pat. Nos. 5,858,112, issued Jan. 12, 1999 to Stokes et al. and
5,962,515, issued Oct. 5, 1999 to Haynes et al. or other material such as described by
U.S. Pat. No. 4,720,415, issued Jan. 19, 1988 to Vander Wielan et al. or any super absorbent material such as described in
U.S. Pat. Nos. 4,995,133, issued Feb. 1991 and
5,638,569 both issued to Newell,
5,960,508, issued Oct. 5, 1999 to Holt et al., and
6,003,191, issued Dec. 21, 1999 to Sherry et al., all of which are hereby expressly incorporated by reference herein.
[0059] In one embodiment, the cleaning pad 28 may comprise a spunbound fiber nonwoven web
having a basis weight of approximately 68 grams per square meter. The spunbound fibers
may comprise bicomponent fibers having a side-by-side configuration where each component
comprises about 50%, by volume, of the fiber. The spunbound fibers will comprise first
and second polypropylene components and/or a first component comprising polypropylene
and a second component comprising propylene-ethylene copolymer. About 1% or more or
less of titanium oxide or dioxide is added to the fiber(s) in order to improve fiber
opacity. The spunbound fiber nonwoven web is thermally bonded with a point unbonded
pattern. The nonwoven web is bonded using both heat and compacting pressure by feeding
the nonwoven web through a nip formed by a pair of counterrotating bonding rolls.
The bonding rolls comprise one flat roll and one engraved roll. The bonded region
of the nonwoven web comprises a continuous pattern that corresponds to the pattern
imparted to the engraved roll. Further, the bonded region is applied to the web when
it passes through the nip. The bonded region will range between approximately about
27% to about 35% of the area of the nonwoven web and forms a repeating, non-random
pattern of circular unbonded regions. Other absorbency enhancing or superabsorbent
materials, including superabsorbent polymers, powders, fibers and the like may be
combined with the cleaning pad 28.
[0060] Alternatively, the pad 28 may comprise a laminate of an air-laid composite and a
spunbound fiber nonwoven web. The nonwoven web may comprise monocomponent spunbound
fibers of polypropylene having a basis weight of approximately 14 grams per square
meter. The air-laid composite may comprises from about 85% to about 90% kraft pulp
fluff and from about 10% to about 15% bicomponent staple fibers. The bicomponent staple
fibers may have a sheath-core configuration; the core component comprising polyethylene
terephthalate and the sheath component comprising polyethylene. The air-laid composite
has a basis weight between about 200 and about 350 grams per square meter and an absorbency
of between about 8 and about 11 grams per sqaure meter.
[0061] The cleaning pad 28 may also include a portion or side of hydrophilic fibers useful
for scrubbing. Additionally, nylon fibers may be used to increase the coefficient
of friction when they become wet. Portions of the cleaning pad 28 may be composed
of microfibers and ultra-microfibers having a denier per filament (dpf) less than
or equal to about 1.0.
[0062] As described, the cleaning pad 28 can be formed by any material or material-forming
process known, including woven and non-woven materials, polymers, gels, extruded materials,
laminates, layered materials which are bonded together integrally and thus form a
co-material, fused materials, extruded materials, air laying, etc.
[0063] The cleaning pad 28 can alternatively be optimized for providing a cleaning fluid
to the surface, such as with micro capsules or encapsulated fluids or agents. The
enhanced surface of the cleaning pad 28 can have scrubbing or abrasive qualities.
The enhanced surface can also be formed by a mechanical stamping, bonding, pressing,
compression, extrusion, sprayed, sputtered, laminated or other surface forming or
affecting process. The various alternative solutions discussed above could be microencapsulated
into the cleaning pad such that they are selectively released by some additional stimulus,
e.g., activated by water, another chemical in the fluid reservoir or pressure. The
solutions could also be dry impregnated. Alternatively, the chemical solutions could
be encapsulated in pockets or bubbles on or within the pad 28 or on the cleaning pad
support member 26. For example, these pockets could be designed to burst and release
the cleaning solution upon the application of moderate pressure.
[0064] FIGS. 1, 5 and 6 illustrate the inventive cleaning system in alternating but non-limiting
positions. FIG. 5 illustrates the cleaning system 20 in a cleaning position suitable
for cleaning behind appliances such as a stereo 70. As illustrated in FIG. 5, the
flexible cleaning pad support 26 maybe bent at an angle of about 90° in relation to
the handle portion 24, such that a user can dust the back surface 72 of the stereo
without moving the stereo 70 or any of its component parts. In order to form the 90°
angle, a user simply bends the flexible cleaning pad support member 26 at a desired
junction. Thus, in the cleaning position, a user may manipulate the cleaning system
20 via the handle portion 24.
[0065] FIG. 6 illustrates the cleaning system 20 in a second hook-like cleaning position
suitable for cleaning or dusting circular features such as the spindle 81 of a staircase
83. In order to move the cleaning pad support member 26 from the first position illustrated
in FIG. 5 to the position in FIG. 6, a user preferably holds the handle portion 24
and applies torque to the flexible cleaning pad support member 26 to move it from
the cleaning position illustrated in FIG. 1 to the curved orientation illustrated
in FIG. 6. As sufficient torque is applied to overcome the forces of the flexible
support member, the support member rotates downwardly into the position illustrated
in FIG. 6. FIG. 1 illustrates the cleaning system in yet another alternative cleaning
position. In FIG. 1, the cleaning pad support member is straight and in substantial
alignment with the axis of the handle portion 24. This cleaning position is suitable
for the cleaning of large surfaces such as a dining room table. During dusting or
cleaning, a user may repeatedly rotate the cleaning pad support member to any variety
of cleaning positions as needed.
[0066] FIGS. 7-11 illustrate a second embodiment of the preferred cleaning system and FIGS.
12-14 illustrate a third embodiment of the preferred cleaning system. As will become
apparent from the description that follows, the cleaning systems illustrated in FIGS.
7-14 are designed for use in wet, damp or dry cleaning and include a fluid reservoir
or liquid delivery system within a pivotally attached handle. The cleaning system
allows for fluid application directly to a cleaning pad or to a surface to be cleaned.
The alternative embodiments of the cleaning system preferably include a cleaning tool
that includes a handle defining a fluid reservoir receiving cradle and a pivotally
attached cleaning pad support member. In addition to the benefits of the flexible
duster previously described, this results in a single hand operated tool that provides
options for wet, damp or dry cleaning not available in traditional cleaning devices.
One should note that the handle and reservoir shown in, e.g., FIGS. 7-11, could be
combined with the support 26 of, e.g., FIG. 1 for yet another embodiment.
[0067] FIGS. 7-11 illustrate a second embodiment of the preferred cleaning system 220. Cleaning
system 220 is generally comprised of a cleaning device or tool 222, including a handle
portion or handle 224 pivotally or moveably attached to a flexible cleaning pad support
member, cleaning pad support, flexible support rod or flexible support member 226,
and a cleaning pad or cleaning implement 228 attached to the cleaning tool 222 via
the cleaning pad support member 226.
[0068] As illustrated by FIGS. 7-11, handle portion 224 is preferably a curved ergonomically
designed member configured to comfortably fit within the palm of a hand of a user.
Handle portion 224 includes an integral top 223, first sidewall 225a, second sidewall
225b, rear wall 227 and bottom. Handle portion 224 may be constructed from a variety
of synthetic resins, plastics or other suitable materials. In the preferred embodiment,
handle portion 224 is constructed from polypropylene. Although the handle portion
224 may be constructed in a wide variety of sizes depending on the intended use, in
the preferred embodiment, handle portion 224 is approximately 8.5 inches or 215.9
mm long, 1.3 inches or 33.2mm wide and 1.7 inches or 43.18mm high. These preferred
dimensions allow for ease of use, manipulation, packaging, shipping and storage of
the cleaning system 220 as well as increasing the overall ergonomics of the design.
Handle portion 224 may be constructed in a variety of colors for increased aesthetic
appeal. It may additionally be constructed from a translucent material.
[0069] As will be described in greater detail below, handle portion 224 defines a fluid
reservoir-receiving cradle, recess or bay 231. In the preferred embodiment, the insertion
of the fluid dispenser or reservoir 233 into the cradle 231 finishes the ergonomic
design or form of the handle portion 224. Thus, the palm of a user's hand extends
over the top 223 handle portion 224 and the user's fingers extend at least partially
around the fluid reservoir 233. Additionally, the preferred curved ergonomic design
of the handle portion 224 is constructed in a manner such that the pivot point defined
by the pivot member receiving cavity 235 is located below the horizontal plane defined
by the fluid reservoir 233 within the cradle 231. Such an orientation is advantageous
in maximizing fluid application as discussed in greater detail below.
[0070] Near the center of the handle portion 224 is an opening or hole 237 extending through
handle portion 224 into the bottom of the handle portion. In the illustrated embodiment,
opening 237 is approximately 2.5 inches, or 6.5mm. from a pivot member receiving cavity
235 located at the forward end of the handle portion 324. As illustrated in FIG. 7,
opening 237 provides a user single-handed access into a fluid reservoir-receiving
cradle, recess or bay 231 defined in the bottom of the handle portion 224. Near the
forward end of the handle portion 224, above the pivot member receiving cavity 235
is a cantilevered pivot engagement tab 241, extending downwardly into the pivot member
receiving cavity 235 described in greater detail below.
[0071] FIGS. 7, 8, 9, and 13 illustrate one preferred embodiment of a fluid reservoir 233
of the cleaning system 220. In the illustrated embodiment, fluid reservoir 233 is
in the form of a fluid dispenser or a pump-activated spray bottle configured to retain
water or a specialized fluid. The fluid may generally comprise, without limitation:
any all-purpose cleaner, oil or water based dust inhibitor, anti-static, anti-microbial,
antibacterial, sanitizing and de-odorizing agent, dusting agent, glass cleaner, furniture
polish, leather or vinyl treatment, other cleaning agent, wax, polish or shining agent,
softening agent, friction-enhancing compound, perfumes, dish cleaner, soap, insect
repellent or insect barrier, exfoliator or other personal care product, paint for
sponge painting or other application, water out emulsions, oil out emulsions, dust
mite killer or repellant, abrasive cleaner, shoe polish, pet sanitation products,
etc. known products. Known products include commercially available Pledge® Multi-Surface
Cleaner, Pledge® Wood and Glass Cleaner, End Dust®, Fantastic® all purpose cleaner,
Windex® glass cleaner, anti-bacterials such as Oust® or Lysol®, fragrances such as
Glade®, leather or vinyl treatment such as Armor All®, fabric protectors such as Scotch
Guard®, or fabric fresheners such as those manufactured by S.C. Johnson & Son, Inc.
of Racine, Wisconsin, or Fabreze®.
[0072] The preferred spray bottle is a generally cylindrical bottle having an integral bottom,
sidewall, second and third sections as disclosed in
U.S. Patent Application Ser. No. 11/045,204, filed January 28, 2005 and incorporated by reference herein. As best described in
U.S. Patent Application Ser. No. 11/045,204, a spray cap or nozzle is screwed or press fitted onto the top of the spray bottle.
The spray cap includes a pair of opposed flats configured to selectively engage flanges
of the fluid reservoir-receiving cradle 231. Alternatively, a system of tabs and grooves
could be used to form a similar locking mechanism. The spray cap could alternatively
include a one sided flat button or a tapered button. In addition, the fluid reservoir
233 could take a variety of forms including but not limited to an aerosol package,
a deformable handle or reservoir that dispenses fluid by squeezing, a squirt gun or
a flexible pouch with an attachable spray nozzle. While the fluid reservoir 233 is
illustrated as fitting within the cradle 231 of the handle portion 224, the fluid
reservoir 233 may alternatively completely form the handle of the system, having only
the upper portion of the cleaning system attached (i.e. the pivot member and the attachment
members).
[0073] As best described in
U.S. Patent Application Ser. No, 11/045,204, opposed flats of the spray cap can be used to provide for a tight fit within the
handle portion 224, and further serve to properly orientate the fluid reservoir 233
within the cleaning system 220. Alternatively, it is understood that the fluid reservoir
233 could include other uniquely designed contours that allow for a mating tight fit
within the fluid reservoir-receiving cradle 231.
[0074] U.S. Patent Application Ser. No. 11/045,204 illustrates one preferred embodiment of the fluid reservoir-receiving cradle 231
configured to retain the fluid reservoir 233. Cradle 231 is generally defined by a
lower support, handle portion sidewalls and two U-shaped supports or rails and configured
to receive the fluid reservoir 233 of the preferred embodiment. In the preferred embodiment
illustrated in
U.S. Patent Application Ser. No. 11/045,204, the lower support is comprised of a plurality of ribs extending from the inner side
of rear wall of handle portion 224. The forward ends of the ribs define the lower
support configured to support the bottom 244 of the fluid reservoir 233. In the preferred
embodiment, ribs include a central rib having a length roughly equal to the diameter
of the bottom of the fluid reservoir 233. The remaining ribs define progressively
shorter lengths, thereby tapering off from the central rib and supporting the remainder
of the circular bottom of the fluid reservoir. A pair of triangular retention tabs
extend along opposed sides of the cradle 231 near the lower support. The retention
tabs are configured to frictionally engage and retain the lower sidewall of the fluid
reservoir 233. Extending forwardly from the retention tabs, the sidewalls of the cradle
further define the sides of the fluid reservoir-receiving cradle 231 and are spaced
in a manner to tightly fit around the sidewall of the fluid reservoir 233.
[0075] While in the illustrated preferred embodiment shown in the present application and
in
U.S. Patent Application Ser. No. 11/045,204, the fluid reservoir 233 is press fit or friction fit within the cradle 231 of the
handle portion 224, it is recognized that alternative configurations could be utilized
to retain the fluid reservoir 233 within the handle portion 224. For example, Velcro@
or rubber bands could be included on a segment of the handle portion 224 in order
to retain the fluid reservoir 233 within the handle portion 224. Other support structures
or retaining features could be hingedly or otherwise attached to the handle portion
224 to retain the fluid reservoir 233 within the handle portion 224.
[0076] As illustrated in
U.S. Patent Application Ser. No. 11/045,204, near the forward end of the fluid reservoir-receiving cradle 231 is a first U-shaped
bottleneck receiving support. First bottleneck receiving support is configured to
press fit around, receive and retain the fluid reservoir of the preferred embodiment.
First bottleneck receiving support is configured to press fit around the fluid reservoir
near the junction of the second and third sections of the reservoir.
[0077] Slightly forward of the first bottleneck receiving support is a second U-shaped spray
cap receiving support. Spray cap receiving support is configured to press fit around,
retain and orientate the spray cap of the fluid reservoir. Spray cap receiving support
is defined by a pair of flanges extending from the inner side of opposed sidewalls.
The flanges are configured to press fit around flats of fluid reservoir spray cap
when the reservoir is placed within the cradle 231. The tight fit defined by flanges
and flats serves to properly orientate spray cap within the fluid reservoir-receiving
cradle 231 such that the spray cap faces in a direction away from the cradle 231.
Forward of the opening 237, are a plurality of structural support ribs extending forwardly
towards the pivot member receiving cavity 235.
[0078] As best illustrated in FIGS. 6 and 11 of
U.S. Patent Application Ser. No. 11/045,204, at the forward end of the bottom of the handle portion 224 is a pivot member receiving
cavity 235, Pivot member receiving cavity 235 is defined between integral opposed
ears 243a, 243b located at the forward end of the handle portion 224. Ears 243a, 243b
include opposed grooves on their inner cavity surface configured to slidably engage
the axles of a circular pivot member during assembly. Grooves have a width that is
equal to or slightly wider than the diameter of the axles of the circular pivot member.
It is understood that grooves and the pivot member receiving cavity 235 are configured
to accommodate a variety of alternative cleaning pad support members 226 or other
cleaning implements having pivot members attached at their proximal ends.
[0079] At the terminal end of the grooves, are pivot holes 245 configured to receive the
axles of the circular pivot member and allow pivotable motion therein. A curved slot
extends laterally from grooves and defines a passage configured to allow the movement
of circular pivot retention tabs extending from the pivot member. On opposed sides
of the forward end of the pivot member receiving cavity 235 are circular pivot retention
tab holes 247 configured to engage and receive the circular pivot retention tabs located
on the pivot member.
[0080] As best illustrated in
U.S. Patent Application Ser. No. 11/045,204, projecting downwardly from the top 223 of the handle portion 224 into the pivot
member receiving cavity 235 is a resiliently biased semi-flexaible pivot engagement
tab 241. Engagement tab 241 is comprised of a first end attached to the handle portion
224 and a second free end configured to engage notches on the outer surface of the
pivot member.
[0081] Turning now to FIG. 7 of the present application, attached within the pivot member
receiving cavity 235 of the handle portion 224 is the cleaning pad support member
226. Cleaning pad support member 226 is comprised of an integral circular pivot member
(not shown), linking section 251 and a two part support head generally designated
253. As best illustrated in
U.S. Patent Application Ser. No. 11/045,204, circular pivot member includes integral axles on its opposed lateral sides. The
axles are configured to fit within pivot holes 245 and rotatably pivot therein. Pivot
member also includes a circular pivot retention tab. Circular retention tab is configured
to fit within retention tab holes 247 and support the system is in the cleaning position.
The pivot member defines three notches or indentations corresponding to alternative
positions of the cleaning pad support member 226. A cleaning position notch, liquid
application notch and storage position notch are defined on the external surface of
the pivot member. In general, the preferred pivot assembly requires about between
2-3 1bf of pivot force in order to rotate it.
[0082] Integral with and extending from the pivot member is the linking section 251 and
two part support head 253. In the preferred embodiment, the two part support head
253 of cleaning pad support member 226 includes a semi-rigid first part 255 comprised
of a pair of parallel attachment members 257a, 257b, and a flexible second part 259
comprised of an insert molded wire spine 261. As illustrated in FIGS. 8-10, both the
first part 255 and second part 259 are configured to engage a pocket or sleeve 271
(shown in phantom) of a cleaning pad 228 as is generally known in the art. Attachment
members 257a, 257b may be spaced apart in a variety of configurations, however, in
the preferred embodiment, attachment members 257a, 257b have a total width of about
1.25 inches, or 3.18mm. from opposed outside lateral edges. The preferred attachment
members 257a, 257b are about .75 inches, or 1.91mm. thick and about 80 inches, or
2.03mm. wide. It is recognized that although the preferred embodiment illustrates
a pair of attachment members 257a, 257b multiple configurations may be utilized. For
example, a single, wider attachment member could be utilized as shown for e.g, in
the third embodiment illustrated in FIGS. 12 and 13. Alternatively, three or more
attachment members could be utilized.
[0083] Attachment members 257a, 257b include a plurality of spaced cleaning pad retaining
tabs, barbs or projections 263 projecting from their upper surface. In the illustrated
embodiment, retaining tabs 263 are triangular-shaped tabs having a first wall 265
extending in a generally vertical direction from the upper surface of the attachment
members 257a, 257b and a second angled wall 267 sloping from the upper edge of the
first wall 265 towards the distal end of the attachment members 257a, 257b. Tabs 263
are preferably raised about .05 inches, or 0.13mm. from the attachment members 257a,
257b. The unique triangular configuration of the retaining tabs 253 serves a dual
function. The angled wall 267 allows for ease of placement of the cleaning pad 228
on the attachment members 257a, 257b during assembly, while the vertical first wall
265 retains the cleaning pad 228 on the attachment members 257a, 257b during the cleaning
motion.
[0084] In addition to the unique configuration of the retaining tabs 263, their orientation
on the attachment members 257a, 257b also serves to maintain the cleaning pad 228
on the attachment members 257a, 257b. In one embodiment, the attachment members 257a,
257b may be expandable, inflatable, partially inflatable, or include an inflatable
portion. The inflatability provides for an improved fit of the cleaning pad 228 on
the attachment members 257a, 257b as well as facilitating hands free removal of the
cleaning pad 228 from the attachment members 257a, 257b.
[0085] As illustrated in FIGS. 7-11, the second part 259 of the cleaning pad support member
226 includes molded living hinges preferably with a wire traversing defining an insert
molded wire-like spine 261. Preferably, a piece of wire 275 is insert-molded into
a plurality of polymer spine vertabrae 277 to form the wire spine 261. The wire 275
is retained only at the first vertebra 287 in the spine 261 and floats through the
remaining part of the spine 261, allowing the spine 261 to bend easily. A variety
of known materials could be used for the wire 275 including Bx cable or other known
wires or flexible materials.
[0086] Although it is recognized that the components of the wire spine 267. could take a
variety of shapes, in the illustrated embodiments, the wire spine includes a plurality
of hingedly connected hexagonally-shaped support vertebrae 277 interconnected by bridge
portions 279. The hexagonally shaped vertebrae 277 include parallel outer sides 281a,
281b and four angled walls 283a-d connecting each individual vertebra 277 with the
bridge portions 279. Preferably, the outer sides 281a, 281b of the hexagonal vertebrae
are spaced apart a distance that generally corresponds to the width af the pocket
or sleeve 271 of the cleaning pad 228 such that a tight fit of the cleaning pad 228
on the cleaning pad support member 226 can be achieved. The center of each vertebra
277 includes a circular opening 285 through which the coated wire 275 passes.
[0087] The wire spine 261 preferably includes a first vertebra 287 connected to or integral
with the first part 255 of the cleaning pad support member 226. In addition, a terminal
vertebra 289 is located at the distal end of the wire spine 261 opposite the first
vertebra 287. The terminal vertebrae 289 preferably includes a rounded tip 291 that
also allows for ease of insertion of the cleaning pad 228 on the cleaning pad support
member 226. In the illustrated embodiment, terminal vertebrae 289 includes a plurality
of slots or grooves 293.
[0088] The second embodiment illustrated in FIGS. 7-11 provides a flexible cleaning pad
support member 226 that is light enough for the user to bend easily, but stiff enough
to retain its shape while in use. Insert-molding the wire 275 prevents the wire 275
from kinking as it would if it were not insert-molded and just naked. The wire 275
is retained only at one end in the spine 261 and floats through the remaining part
of the spine 261, allowing the spine 261 to bend easily.
[0089] FIGS. 12-14 illustrate a third embodiment of the preferred cleaning system 320. Cleaning
system 320 is generally comprised of a cleaning device or tool 322, including a handle
portion or handle 224 pivotally or moveably attached to a flexible cleaning pad support
member, flexible support rod or flexible support member 326, and a cleaning pad or
cleaning implement 328 attached to the cleaning tool 322 via the cleaning pad support
member 226.
[0090] It should be apparent for the drawings that the third embodiment includes an identical
handle portion 224 defining a fluid reservoir-receiving cradle, recess or bay 231,
for receiving a fluid dispenser or reservoir 233 to that described in reference to
FIGS. 7-11 and therefore the details of those parts need not be described and will
be referred to using like reference numerals.
[0091] Turning now to FIG. 12 of the present application, attached within the pivot member
receiving cavity 235 of the handle portion 224 is the cleaning pad support member
326. Cleaning pad support member 326 is comprised of an integral circular pivot member
(not shown); linking section 351 and a two part support head generally designated
353.
[0092] In the illustrated embodiment, the two part support head 353 of cleaning pad support
member 326 includes a first part 355 comprised of a single widened semi-rigid attachment
member 357, and a second part 359 defining a flexible spine 361.
[0093] As illustrated in FIGS. 12-13, both the first part 355 and second part 359 are configured
to engage a pocket or sleeve 371 (shown in phantom) of a cleaning pad 328 as is generally
known in the art. Sleeve 371 defines a narrower portion 372 configured to receive
the second part 359 of the cleaning pad support member 326 and a wider portion 374
configured to receive the first part 355 of the cleaning pad support member 326.
[0094] Attachment member 357 is preferably constructed from a semi-rigid material similar
to that used to construct the handle. Preferably the attachment member 357 has a total
width of about 1.25 inches, or 3.18mm from opposed outside lateral edges. The preferred
attachment member is about 75 inches, or 1.191mm thick Attachment member 357 includes
a plurality of spaced cleaning pad retaining tabs, barbs or projections 363 projecting
from its upper surface. In the illustrated embodiment, retaining tabs 363 are triangular-shaped
tabs having a first wall 365 extending in a generally vertical direction from the
upper surface of the attachment member 357 and a second angled wall 367 sloping from
the upper edge of the first wall 365 towards the distal end of the attachment member
357. Tabs 363 are preferably raised about .050 inches, or 0.13mm from the attachment
member 357.
[0095] As illustrated in FIGS. 12-14, the second part 359 includes a flexible spine 361
similar to that described in the embodiment shown in FIGS. 1-6. The flexible spine
361 may be attached to the attachment member 357 in a variety of conventional ways.
The elongated flexible spine 361 is capable of being manually moved into a plurality
of differing shapes while at the same time exhibiting enough strength to maintain
its position during dusting or cleaning.
[0096] In the embodiment illustrated in FIGS. 12-14, the elongated flexible spine 361 is
of the type marketed by Lockwood Products, Inc. under the trade designation LOC-LINE®.
The elongated flexible spine 361 comprises a plurality of interconnected segments
340.
[0097] As illustrated in FIGS. 12-14, each segment 340 comprises a central body portion
342, a male end portion 394 and a female end portion 346. The male end portion 344
has an outer surface 348 comprising a frustum of a sphere and the female end portion
346 has a mating inner surface 350 comprising a frustum of a sphere which is dimensioned
so that, when the male end portion 344 is inserted into the female end portion 346,
there is frictional contact between the mating male end portion outer surface 348
and female end portion inner surface 350. These frictional forces function as retaining
means to hold one segment 340 at any desired location relative to an interconnected
segment 340. However, these frictional forces can be overcome permitting interconnected
segments 340 to be moved relative to each other so that their longitudinal axes are
either in or out of alignment and permitting unrestricted relative rotational movement
therebetween. Thus, the static friction hold the segments in place and is overcome
when a user initially starts moving the segments. Once in motion, the low dynamic
friction that makes the segments 340 easy to move. This connection permits the attached
cleaning pad 328 to have the same relative movements as the interconnected segments,
as described above. The length of the elongated flexible cleaning pad support member
326 can be changed by adding or removing segments 340.
[0098] It should be understood that the component parts of the alternative embodiments can
be interchanged. FIGS. 15 and 16 illustrate a fourth and fifth embodiment incorporating
the handle portion 24 of the first embodiment with the cleaning head support members
226, 326 of the second and third embodiments respectively. Although not shown, it
should be understood that the cleaning head support could be constructed entirely
of the wire spine molded to the handle portion without the pivot member or a semi-rigid
first part 255 in a manner similar to that described in reference to the first embodiment.
[0100] FIGS. 17-20 illustrate a sixth embodiment of the preferred cleaning system 520. Cleaning
system 520 is generally comprised of a cleaning device or tool 522, including a handle
portion or handle 224 pivotally or moveably attached to a flexible cleaning pad support
member, cleaning pad support, flexible support rod or flexible support member 526,
and a cleaning pad or cleaning implement 528 attached to the cleaning tool 522 via
the cleaning pad support member 526. Cleaning system 520 preferably includes a pair
of bendable attachment members 508a, 508b.
[0101] As illustrated by FIGS. 17-20, handle portion 224 is a curved ergonomically designed
member configured to comfortably fit within the palm of a hand of a user and is identical
to that previously described in relation to FIGS. 7-14.
[0102] Turning now to FIG. 18, at the forward end 525 of the bottom 531 of the handle portion
224 is a pivot member receiving cavity 235. Pivot member receiving cavity 235 is defined
between integral opposed ears 243a, 243b located at the forward end 525 of the handle
portion 224. Ears 243a, 243b include opposed grooves 552a, 552b on their inner cavity
surface configured to slidably engage the axles 580a, 580b of a circular pivot member
582 during assembly. Grooves 552a, 552b have a width that is equal to or slightly
wider than the diameter of the axles 580a, 580b of the circular pivot member 582.
It is understood that grooves 552a, 552b and the pivot member receiving cavity 235
are configured to accommodate a variety of alternative cleaning pad support members
526 or other cleaning implements having pivot members 582 attached at their proximal
ends.
[0103] At the terminal end of the grooves 552a, 552b, are pivot holes 245 configured to
receive the axles 580a, 580b of the circular pivot member 582 and allow pivotable
motion therein. A curved slot (not shown) extends laterally from grooves 552a, 552b
and defines a passage configured to allow the movement of circular pivot retention
tabs (not shown) extending from the pivot member 582. On opposed sides of the forward
end of the pivot member receiving cavity 235 are circular pivot retention tab holes
587a, 587b configured to engage and receive the circular pivot retention tabs located
on the pivot member 582.
[0104] Projecting downwardly from the top of the handle portion 224 into the pivot member
receiving cavity 235 is a resiliently biased semi-flexible pivot engagement tab 241.
Engagement tab 241 is comprised of a first end 539 attached to the handle portion
224 and a second free end 591 configured to engage notches 585 on the outer surface
of the pivot member 582 as will be described in greater detail below.
[0105] Attached within the pivot member receiving cavity 235 of the handle portion 224 is
the cleaning pad support member 526. Cleaning pad support member 526 is comprised
of an integral circular pivot member 582, linking section 593 and support head generally
designated 592. Circular pivot member 582 includes integral axles 580a, 580b on its
opposed lateral sides. Axles 580a, 580b are configured to fit within pivot holes 245
and rotatably pivot therein. Pivot member 582 defines at least three notches or indentations
555 corresponding to alternative positions of the cleaning pad support member 525.
Preferably, a cleaning position notch, liquid application notch and storage position
notch are defined on the external surface of the pivot member 582. In general, the
preferred pivot assembly requires about between 2-3 lbf of pivot force in order to
rotate it.
[0106] Integral with and extending from the pivot member 582 is the linking section 593
and support head 592. In the preferred embodiment, support head 592 of cleaning pad
support member 526 includes a pair of parallel bendable attachment members or attachment
prongs 508a, 508b configured to engage the pockets or sleeves 510a, 510b of a cleaning
pad 528 as is generally known in the art. Attachment members 508a, 508b may be spaced
apart in a variety of configurations. Preferably, attachment members are constructed
from a bendable material such as plastic, that will retain a plurality of different
shapes. Attachment members 508a, 508b define a rounded leading edge 507 configured
for ease of insertion into the sleeves 510a, 510b of cleaning pad 528. It is recognized
that although the preferred embodiment illustrates a pair of attachment members 508a,
508b multiple configurations may be utilized. For example, a single, wider attachment
member could be utilized. Alternatively, three or more attachment members could be
utilized.
[0107] Attachment members 508a, 508b include a plurality of spaced cleaning pad retaining
tabs, barbs or projections 563 projecting from their upper surface. In the illustrated
embodiment, retaining tabs 563 are triangular-shaped tabs as previously described
in the previous embodiments. As previously noted, the attachment members 508a, 508b
may be expandable, inflatable, partially inflatable, or include an inflatable portion.
The inflatability provides for an improved fit of the cleaning pad 528 on the attachment
members 508a, 508b as well as facilitating hands free removal of the cleaning pad
528 from the attachment members 508a, 508b.
[0108] FIGS. 19 and 20 better illustrate features of the cleaning pad support member 526.
As illustrated in the exploded views, the attachment members 508a, 508b of the cleaning
pad support member 528 preferably include respective insert plates 530a, 530b inserted
into the bendable attachement members 508a, 508b. The insert plates 530a, 530b act
as a retaining means and allow the attachment members 508a, 508b to be manually moved
into a plurality of differing shapes while at the same time exhibiting enough strength
to maintain their position during dusting or cleaning.
[0109] As noted above, attachment members 508a, 508b are preferably constructed from a bendable
material such as plastic. While attachment members 508a, 508b can take on a wide variety
of alternative configurations, in the illustrated embodiment, attachment members 508a,
508b include a plurality of inward curves 532 and slotted regions 534 comprised of
a plurality of individual slots 535. The described architecture enables the attachment
members 508a, 508b to be moved into a plurality of alternative shapes while still
being constructed from stiffer plastics. The curves 532 and slotted regions 534 of
the attachment members 508a, 508b provide for regions of increased flexibility in
comparison to the remaining portions of the attachment members 508a, 508b, thereby
allowing for increased flexibility.
[0110] Insert plates 530a, 530b have a shape that preferably correspond to a portion of
the attachment members 508a, 508b. As illustrated in FIGS. 19 and 20, insert plates
530a, 530b preferably include curved portions 536 corresponding to curved portions
532 on attachment members 508a, 508b. Insert plates 530a, 530b also include holes
538 that may be used to secure insert plates 530a, 530b within attachment members
508a, 508b.
[0111] Insert plates 530a, 530b are preferably constructed from a material such as metal
and may be insert molded into attachment members 508a, 508b. For example, aluminum
or copper insert plates could be utilized. Other materials such as rubber or plastic
may also be used. It is preferred that insert plates 530a, 530b be maleable enough
to be bent into several shapes without breaking or snapping.
[0112] The sixth embodiment illustrated in FIGS. 17-20 therfore provides a flexible cleaning
pad support member 526 having two attachment members 508a, 508b that are light enough
for the user to bend easily, but stiff enough to retain their shape while in use.
[0113] The cleaning pad 528 utilized with the sixth embodiment is largely similar in materials
and construction to that previously described. As noted, cleaning pad 528 may be comprised
from a single cleaning pad or from multiple cleaning pads attached sequentially to
cover the cleaning pad support member 526. Cleaning pad 528 is generally known in
the art and comprised of a combination of fibers defining a cleaning surface 564 and
attachment portion 562. In the illustrated embodiment, attachment portion 562 defines
a pocket or sleeve 565 configured to tightly fit over support member 526. Attachment
portion 562 may be constructed from an elastic material to snuggly fit over the support
member 526. Although in the illustrated embodiment, sleeve 565 is illustrated as having
an open end and a closed end, it should be recognized that the sleeve 565 could have
two open ends to allow the cleaning pad to be reversible and insertable on the support
member 526 from either end. The reversibility of the cleaning pad 528 would allow
for maximum use of the cleaning pad,
Methods of Use and Methods of Cleaning
[0114] It should be appreciated from the above disclosure that the preferred cleaning tools
22, 222, 322, 522 can be utilized to clean or dust a variety of surfaces. Due to the
unique configuration of the tool 22, 222, 322, 522 a user can conveniently alternate
the orientation of the cleaning tool 22, 222, 322, 522. It is recognized that the
component parts of the invention may be conveniently interchanged depending on the
particular cleaning task at hand. For example, some of the disclosed cleaning pads
28, 528 may be more suitable for use with some of the disclosed cleaning solutions
or for dry dusting. Likewise, some cleaning pads 28, 528 may include alternate surfaces
configured for alternative cleaning tasks. Similarly, the particular cleaning solution
utilized can be changed depending on the desired application.
[0115] In order to perform cleaning a user may obtain the above mentioned cleaning system
20, 220, 320, 520 that includes the preferred cleaning tool 22, 222, 322, 522. A user
holds the cleaning tool 22, 222, 322, 522 such that the palm of the users hand surrounds
the handle portion 24, 224.
[0116] Once the user obtains the tool 22, 222, 322, 522 a user then places the cleaning
pad 28, 228, 328, 528 onto the flexible cleaning pad support member 26, 223, 326,
526. As noted above, the cleaning tool may be used with a variety of alternative cleaning
pads. In the preferred embodiment, the sleeve-like cleaning pad 28, 228, 328, 528
is mounted over the cleaning pad support member 26, 226, 326, 526. Once secured, the
user then positions the cleaning pad 28, 228, 328, 528 onto a surface to be cleaned
and moves the cleaning pad 28, 228, 328, 528 on the surface to be cleaned. The movement
of the cleaning pad 28, 228, 328, 528 across the surface to be cleaned causes dust
or other debris to be collected by the cleaning pad 28, 228, 328, 528, In the illustrated
embodiment, dust or other debris is collected by the cleaning surface of the cleaning
pad 28, 228, 328, 528. The user may, depending on the surface to be cleaned, move
the cleaning pad support member 28, 228, 328, 528 to accommodate hard to reach places.
For example, if a user desires to dust an overhead lintel, the user may pivot the
cleaning pad support member 26, 226, 326, 528 to an angle of about 90° in relation
to the handle portion 24, 224, 324.
[0117] A preferred dusting or cleaning pattern consists of a side to side overlapping motion
starting in the upper left hand (or right hand) side of the section to be cleaned,
and progressing the wiping pattern across the surface to be cleaned continuing to
use side to side wiping motions. Another preferred wipe pattern consists of an up-and-down
wiping motion. The preferred wiping patterns allow the cleaning pad 28, 228, 328,
528 to loosen dirt and dust, and provide a better end result. Another benefit of the
above wiping patterns is minimization of streaks as a result of improved spreading
of solution (in wet dusting). Additionally a user can bend the support member 26,
226, 326, 526 into a "U" shape, so as to provide twice the dusting surface passing
over a given space.
[0118] Once the cleaning or dusting has been finished, the user may remove and dispose of
the cleaning pad 28,228, 328, 528. As noted above, a variety of cleaning solutions
can be used with the inventive cleaning system. In one preferred method of light cleaning
or dusting a solution comprising 96.5125% by weight deionized water, 1.75% propan-2-ol
anhydrous, .40% ethylene glycol monobutyl ether, .40% ethylene glycol n-hexyl ether,
.125% propylene glycol, .10% monoethanolamine, . .30% vinegar (white distilled 300
gram), and small amounts surfactants and other ingredients is utilized. This composition
is ideally suited for dusting jobs. Use of the preferred solution with the inventive
cleaning solution provides an increase in dust and allergen retention as well as providing
an improved shine to the surface to be cleaned. Fingerprints, smudges and other blemishes
are also easily removed.
[0119] Optionally, and most preferably, convenience and performance can be maximized by
using a system composed of a disposable cleaning pad 28, 228, 328, 528 as described
hereinbefore. The pad can be composed of any one of the alternative cleaning pads
described above.
[0120] Use of the embodiments illustrated in FIGS. 7-14 and 17-20 is similar to that described
above, however, includes the additional option of application of a cleaning solution
to the cleaning pad 228, 328, 528 or directly to the surface to be cleaned. FIGS.
7,12 and 17 generally illustrate the cleaning systems 220, 320, 520 in their cleaning
positions. In the cleaning position the cleaning pad support member 226, 326, 526
extends forwardly, pivot engagement tab 241 engages the cleaning position notch of
pivot member, and retention tabs fit within the retention tab holes 247, 347. These
engagement or retaining features create at least 2.51bf of pivot force. This amount
of force is sufficient to maintain the cleaning pad support member 226, 326, 526 in
its fully extending cleaning position despite any torque experienced during normal
dusting, drying, or cleaning motions. Thus, in the cleaning position, 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.
[0121] 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. In order to move, 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. As sufficient torque is applied to overcome the forces of the inventive
engagement features, the circular pivot member rotates downwardly into the liquid
application position. In 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. In the illustrated
embodiment, 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°.
Preferably, 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.
[0122] During dusting or cleaning, a user may repeatedly rotate the cleaning pad support
member 226, 326, 526 from its cleaning position to its liquid application position
as needed. Alternatively, as noted above, 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.
[0123] Although not illustrated, the cleaning system 220, 320, 520 also includes a storage
position. In 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. In this position, engagement tab 241. engages the
storage position notch thereby maintaining cleaning pad support member 226 in its
folded position. In the storage 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.
[0124] 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.
[0125] 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.
[0126] To maximize the synergy between the various cleaning, and dusting tasks, the present
methods can be carried out using several varying executions and instructions for use.
In one embodiment, 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.
[0127] It is understood that the component parts of the 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. For example, and in no way limiting, 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. Numerous other cleaning implements are also within the scope of the
present invention.
[0128] Furthermore, although the preferred embodiment illustrates a flexible cleaning pad
support 26, 226, 326, 526 it is recognized that the present invention is in no way
limited to such a construction. The cleaning pad support 26, 226, 326, 525 could alternatively
be connected to the handle portion via a threaded connection. Such an orientation
would allow for the ease of attachment and removal of the numerous alternative cleaning
implements that are within the scope of the present invention.
[0129] Although the best mode contemplated by the inventors of carrying out the present
invention is disclosed above, practice of the present invention is not limited thereto.
It will be manifest that various additions, modifications and rearrangements of the
features of the present invention may be made without deviating from the spirit and
scope of the underlying inventive concept.
[0130] Moreover, as noted throughout the application the individual components need not
be formed in the disclosed shapes, or assembled in the disclosed configuration, but
could be provided in virtually any shape, and assembled in virtually any configuration,
so as to provide for a cleaning system that includes a flexible support. Furthermore,
all the disclosed features of each disclosed embodiment can be combined with, or substituted
for, the disclosed features of every other disclosed embodiment except where such
features are mutually exclusive.
