Description
TECHNICAL FIELD AND BACKGROUND OF THE INVENTION
[0001] This invention relates to an improved cleaning implement, an
adjustable head for a cleaning implement, and a method for cleaning
a floor surface area. The invention is especially applicable for
use in combination with disposable wet and dry cloths applicable
for mopping and dusting floors, respectively.
[0002] Existing commercial products, such as the electrostatic
cloth marketed under the brands Swiffer.RTM. and Grab-it.RTM.,
represent a substantial improvement over the standard broom in
removing dust, dirt, hair, and other loose debris from floors. For
the most part, sweeping using a standard broom simply stirs up
matter that ultimately resettles on the floor only after the job is
believed to be finished. While the existing products do a
moderately effective job of trapping dust particles before they
have a chance to escape, the real problem lies in the limited
design of the cleaning head used to carry the cloth. Because these
implements utilize an entirely flat cleaning head, when the head
and attached cloth are moved across the floor, all of the dust
collects only at portions of the cloth covering the front and/or
rear edge of the head. Consequently, the cleaning head operates
much like a snowplow with substantially all the loose debris piling
up and accumulating at the leading edge. This debris is generally
pushed around the room, and engages only a very small portion of
the cleaning cloth. The vast majority of the cloth is not
utilized.
[0003] In recognizing this problem, one existing product advertizes
that its dry cloths are extra-thick with "unique, V-shaped ridges
that pick up more dirt, dust, and hair than traditional methods."
Notwithstanding this modification/improvement, because the cleaning
head remains entirely flat, the loose debris continues to be pushed
around and not collected over a vast majority of the cloth surface
area. As a result, a long felt need exists for an improved head
design which enables proper utilization of the entire cloth, and
which more effectively captures and removes dirt, dust, hair, and
other debris from the floor with less work.
SUMMARY OF INVENTION
[0004] Therefore, it is an object of the invention to provide an
adjustable cleaning head for an improved cleaning implement.
[0005] It is another object of the invention to provide a cleaning
head which includes independently adjustable cleaning panels that
work together to utilize the entire cleaning cloth, and thereby
capture and remove a maximum amount of dust, dirt and debris from
the floor.
[0006] It is another object of the invention to provide a cleaning
head which is conveniently adjustable between multiple
configurations.
[0007] It is another object of the invention to provide a cleaning
head which avoids "snowplowing" loose debris and wet spills across
the floor.
[0008] It is another object of the invention to provide a cleaning
head which defines a debris entry and collection zone between the
floor and a raised cleaning panel.
[0009] It is another object of the invention to provide an improved
method for cleaning a floor.
[0010] These and other objects of the present invention are
achieved in the preferred embodiments disclosed below by providing
an adjustable cleaning head for a cleaning implement. The cleaning
head has first and second cleaning panels defining respective first
and second working surfaces. The working surfaces are preferably
generally planar. Means are provided for pivotably attaching the
first cleaning panel to the second cleaning panel, whereby the
first cleaning panel is movable relative to the second cleaning
panel. Means are provided for fixing the position of the first
cleaning panel relative to the second cleaning panel, such that the
first and second working surfaces form a fixed cleaning angle
therebetween. The cleaning angle is greater than 180 degrees and
less than 270 degrees. Preferably, the cleaning angle is
approximately 210 degrees.
[0011] According to another preferred embodiment, the means for
pivotably attaching the first and second cleaning panels is a
living hinge.
[0012] According to another preferred embodiment, the means for
fixing the position of the first cleaning panel includes first and
second interfering elements cooperating to frictionally lock the
first cleaning panel in position relative to the second cleaning
panel.
[0013] According to another preferred embodiment, first and second
panel tabs are located on respective first and second cleaning
panels. The interfering elements are formed with respective panel
tabs.
[0014] According to another preferred embodiment, the interfering
elements include a mating indent and detent formed with respective
panel tabs.
[0015] According to another preferred embodiment, the first
cleaning panel is adjustable between a wet clean position, wherein
the fixed cleaning angle is substantially 180 degrees, and a dry
clean position. In the dry clean position, the fixed cleaning angle
is greater than 180 degrees and less than 270 degrees, and
preferably, approximately 210 degrees. The term "dry clean" refers
primarily to dusting, but is not intended to exclude other cleaning
in this head configuration using wet cloths. Likewise, the term
"wet clean" refers primarily to mopping, but is not intended to
exclude other cleaning in this head configuration using dry
cloths.
[0016] According to another preferred embodiment, a finger post
extends from the first cleaning panel, and is adapted for being
engaged by a user to move the first cleaning panel between the wet
and dry clean positions.
[0017] According to another preferred embodiment, at least one
cloth holder is formed with at least one of the first and second
cleaning panels.
[0018] According to another preferred embodiment, a disposable dry
cloth is adapted for being releasably attached to the at least one
cloth holder.
[0019] According to another preferred embodiment, a disposable wet
cloth is adapted for being releasably attached to the at least one
cloth holder.
[0020] According to another preferred embodiment, a third cleaning
panel is attached to the second cleaning panel, and defining a
third generally planar working surface. Alternatively, the third
working surface may be upwardly curved.
[0021] According to another preferred embodiment, means are
provided for pivotably attaching the third cleaning panel to the
second cleaning panel.
[0022] According to another preferred embodiment, means are
provided for fixing the position of the third cleaning panel
relative to the second cleaning panel, such that the third and
second working surfaces form a fixed cleaning angle
therebetween.
[0023] According to another preferred embodiment, the fixed
cleaning angle between the third and second working surfaces is
greater than 180 degrees and less than 270 degrees.
[0024] In another embodiment, the invention comprises an
upwardly-angled cleaning head for a cleaning implement. The
cleaning head has first and second cleaning panels defining
respective first and second working surfaces. The working surfaces
form a fixed cleaning angle therebetween. The cleaning angle is
greater than 180 degrees and less than 270 degrees. The first and
second cleaning panels may be separately formed, or
integrally-formed together (e.g., molded) as a single unit. The
working surface of the first cleaning panel may extend at a
distinct angle, or may be upwardly curved. In the case of an
upwardly-curved working surface, the cleaning angle is measured
relative to a notional tangent extending from an adjacent edge of
the working surface of the second cleaning panel and touching the
curved working surface of the first panel at a point without
intersecting the point.
[0025] In another embodiment, the invention comprises a method for
cleaning a surface area. The method includes the steps of upwardly
tilting a first cleaning panel relative to a second cleaning panel
of an adjustable cleaning head. The first and second cleaning
panels define respective first and second working surfaces. The
working surfaces are preferably generally planar. The position of
the first cleaning panel relative to the second cleaning panel is
then locked, such that the first and second working surfaces form a
fixed cleaning angle therebetween. The cleaning angle is greater
than 180 degrees and less than 270 degrees. Using the handle, the
adjustable cleaning head is then pushed over the surface area to be
cleaned.

DESCRIPTION OF PREFERRED EMBODIMENT AND BEST MODE
[0031] Referring now specifically to the drawings, an improved
cleaning implement according to the present invention is
illustrated in FIG. 1, and shown generally at reference numeral 10.
The cleaning implement 10 includes an elongated handle 11, an
adjustable cleaning head 12, and a conventional joint 14
interconnecting the handle 11 and head 12. The joint 14 enables
pivoting and swivel movement of the cleaning head 12 relative to
the handle 11.
[0032] The cleaning head 12 comprises multiple pivotably-attached
cleaning panels 15, 16, and 17. The cleaning panels 15, 16, 17 are
preferably joined together by respective longitudinal living hinges
18, 19, such that outside panels 15 and 17 are independently
adjustable relative to the center panel 16. Preferably, the joint
14 interconnecting the handle 11 and cleaning head 12 is formed
with a top of the center panel 16. Each of the cleaning panels 15,
16, 17 defines a generally planar working surface 15A, 16A, and 17A
which cooperates with a disposable wet or dry cloth 20 to clean a
floor surface area, such as wood, vinyl, tile, or other flooring
material. Cloth holders 21, 22, 23, and 24 are located on top sides
of the cleaning panels 15 and 17, and are designed to receive and
hold respective corners of the disposable cloth 20. The disposable
wet cloths, such as those marketed under the Swiffer.RTM. Brand,
are preferably pre-soaked with an advanced cleaning solution that
dissolves stains and dries quickly.
[0033] The position of each outer cleaning panel 15, 17 is
releasably fixable relative to the center panel 16 using any
suitable means. For example, in the embodiment shown, the cleaning
panels 15, 16, 17 comprise overlapping, upstanding, lateral tabs
26, 27, and 28. The outer panel tabs 26 and 28 have respective
detents 31 which, upon upward pivoting movement of the outer panels
15, 17, are designed to selectively mate with complementary indents
32 (or holes) formed with the center panel tab 27. Once mated, as
shown in FIG. 4, the detent 31 and mouth of the indent 32 cooperate
to frictionally retain the outer panel 15, 17 in the desired
selected position during use of the cleaning implement 10. Other
interfering structure, such as spring-loaded pins, cotter pins,
clips, ties, screws, or the like, may be used instead of, or in
addition to, the above to further set the position of the outer
panels 15, 17 relative to the center panel 16.
[0034] Finger posts 33 and 34 extending from each outer panel tabs
26, 28 are adapted for being engaged by the user to move the outer
cleaning panels 15, 17 between the various positions shown in FIGS.
3A, 3B, 3C, and 3D. In FIGS. 1 and 3A, the two outer cleaning
panels 15, 17 are positioned generally coplanar to the center
cleaning panel 16. In this position, the cleaning head 12 is
especially applicable for wet mopping, as each of the working
surfaces 15A, 16A, 17A engages the wet cloth (not shown) to clean
the floor surface area "F". The cleaning angles (.alpha.) and
(.beta.) formed between the first working surface 15A and center
working surface 16A, and between the second working surface 17A and
center working surface 16A, respectively, are each substantially
180 degrees.
[0035] In FIGS. 2 and 3B, both outer cleaning panels 15, 17 are
raised to dry clean the floor surface area using a disposable
electrostatic dusting cloth (not shown). In this position, the
cleaning angles (.alpha.) and (.beta.) between the first working
surface 15A and center working surface 16A, and between the second
working surface 17A and center working surface 16A, respectively,
are each substantially 210 degrees. As the cleaning head 12 is
moved back and forth over the floor surface area "F", dust, dirt,
hair, and other dry loose matter is captured beneath the raised
outer panels 15, 17 and collected on the dry cloth adjacent the
working surfaces 15A, 16A, and 17A. Consequently, the cleaning
panels 15, 16, and 17 and respective working surfaces 15A, 16A, and
17A work together to utilize the entire cloth, and thereby capture
and remove a maximum amount of dust, dirt and debris from the floor
surface area "F". The joint 14 interconnecting the handle 11 and
head 12 allows the user to conveniently reverse the leading and
trailing cleaning panels 15, 17, such that the entire cloth may be
more effectively utilized prior to disposal. The resulting spaces
formed between the floor "F" and working surfaces 15A and 17A
define respective debris entry and collection zones "Z". Larger
dust and dirt particles are captured by the cloth adjacent the
raised surfaces 15A and 17A, while the finer particles pass beneath
the center panel 16 and are captured by the cloth adjacent the
working surface 16A. This head configuration is also applicable for
mopping to pick-up wet spills, such as jelly and syrup.
[0036] FIGS. 3C and 3D illustrate further configurations of the
adjustable cleaning head 12. In FIG. 3C, the outer cleaning panel
15 is raised while the outer panel 17 is positioned generally
coplanar to the center panel 16. In this position, the cleaning
angle (.alpha.) between the first working surface 15A and center
working surface 16A is substantially 210 degrees. The resulting
space formed between the floor "F" and working surfaces 15A defines
a debris entry and collection zone "Z", as previously described.
The cleaning angle (.beta.) between the second working surface 17A
and center working surface 16A is substantially 180 degrees. In
FIG. 3D, the outer cleaning panel 17 is raised while the outer
panel 15 is positioned generally coplanar to the center panel 16.
In this position, the cleaning angle (.beta.) between the second
working surface 17A and center working surface 16A is substantially
210 degrees. The resulting space formed between the floor "F" and
working surface 17A defines a debris entry and collection zone "Z".
The cleaning angle (.alpha.) between the first working surface 15A
and center working surface 16A is substantially 180 degrees.
[0037] In alternative embodiments (not shown), the adjustable head
may include only two cleaning panels pivotably connected together
by living hinge or suitable hardware. The head may also be
integrally molded such that one or both outer cleaning panels are
permanently titled. In this embodiment, the working surfaces define
respective permanent cleaning angles each greater than 180 degrees
and less than 270 degrees, as previously described.
[0038] An adjustable-head cleaning implement is described above.
Various details of the invention may be changed without departing
from its scope. Furthermore, the foregoing description of the
preferred embodiment of the invention and best mode for practicing
the invention are provided for the purpose of illustration only and
not for the purpose of limitation--the invention being defined by
the claims.
