DETAILED DESCRIPTION
[0019] The present invention relates to mops comprising one or more
cleaning members. In select embodiments, a plurality of cleaning
members may be releasably secured to the mop and a portion of the
cleaning members may be capable of compression. In these
embodiments, the different cleaning members enable the mop of the
present invention to operate in a plurality of different modes,
including a wringing mop mode, a damp mop mode and a dust mop mode.
In other embodiments, a portion of the handle of the mop of the
present invention is adapted to hold and release a fluid, such as a
cleaning solution. In these embodiments, the user may cause release
of the fluid through one or more openings associated with the
mop.
[0020] Referring now to FIG. 1, one embodiment of the mop 10 of the
present invention is shown. Generally, this embodiment comprises a
handle 12, which includes an upper end 14 and a lower end 16, a
first actuator 18, a second actuator 20, a mop head 22, a first
cleaning member 24, a second cleaning member 26, and a support
member 28.
[0021] As shown in FIG. 1, the handle 12 comprises a first actuator
18. The first actuator 18 is any of various structures that may
cause compression of a portion of the first and/or second cleaning
members 24 and 26 or any other members attached thereto. In FIG. 1,
the first actuator 18 is a hand grip that, when moved by manual
force toward the lower end 16 of the handle 12, causes compression
of a portion of the first and second cleaning members 24 and 26.
Compression of a portion of the first and second cleaning members
24 and 26 in this manner may be used to release soil-carrying
liquids from the mop 10.
[0022] In FIG. 1, the first actuator 18 is associated with a
connector 32, which in turn, is associated with the mop head 22.
The connector 32 may be disposed inside the handle 12 or
co-extensively with the handle 12 in a parallel relationship, as
seen in FIG. 1. The illustrated first actuator 18 and connector 32
are made of plastic and steel respectively, although various other
materials known to those of skill in the art are suitable.
[0023] Many arrangements for causing compression of a portion of
the first and second cleaning members 24 and 26 are suitable for
purposes of the present invention. For example, in one embodiment,
a so-called butterfly mop arrangement may be employed. As shown in
FIG. 2, the mop head 22 comprises a hinged platen 34, which has a
first side 36 associated with the handle 12 and a second side 38
associated with the first cleaning member 24. The first side 36 of
the hinged platen 34 is also associated with the first actuator 18
through the connector 32. Attached to the connector 32 is a squeeze
member 40 including a pair of opposing arms 42 and 44 positioned
through an aperture in the connector 32.
[0024] The hinged platen 34 of this embodiment further comprises a
support member 28 and a pair of opposing plates 46 and 48,
rotatably secured about a common pivot access A. Manual force on
the first actuator 18 toward the lower end 16 of the handle 12
rotates the opposing plates 46 and 48 about the common pivot axis
A, thereby causing compression of a portion of the first and second
cleaning members 24 and 26. Thus, the hinged platen 34 may be
pivoted between a cleaning position in which the mop may be used to
absorb soil and other debris and a compressed position for
releasing soil-carrying liquids from the first and second cleaning
members 24 and 26. Ramps 49 disposed on the first side 36 of the
hinged platen 34 on either side of handle 12 may be used to
facilitate rotation of the opposing plates 46 and 48 about the
common pivot axis A through movement of the opposing arms 42 and 44
into the ramps 49.
[0025] Alternatively, the mop head 22 may comprise a pair of spaced
apart roller members (not shown) associated with the first actuator
18 through the connector 32. As with the butterfly arrangement,
manual force applied to the first actuator 18 causes compression of
a portion of the first and second cleaning members 24 and 26. Most
often, the roller members are positioned transverse to the handle
12 and are parallel, but not co-linear with one another. In one
embodiment, each roller member comprises a single piece integral
roller including three separate cylindrical segments, separated by
cylindrical axle sections or undercuts of reduced diameters. The
cylindrical axle sections or undercuts are provided so that the
rollers may be engaged by extensions associated with the mop head
22.
[0026] In either of these embodiments, the mop head 22 can be
provided in various shapes and sizes. The mop head 22 may also be
configured for many different types of cleaning, such as cleaning
walls, around corners, furniture and the like.
[0027] In accordance with another aspect of the present invention,
one embodiment of the mop 10 comprises multiple cleaning members.
In select embodiments, each of the cleaning members may be
releasably secured to the second side 38 of the hinged platen 34.
As shown in FIGS. 3 and 4, various cleaning members may be
employed, including but not limited to the first cleaning member
24, the second cleaning member 26 and a third cleaning member 27.
In one embodiment of the present invention, the first cleaning
member 24 is constructed of a sponge-like material, the second
cleaning member 26 is in the form of a dry sheet and the third
cleaning member 27 is in the form of a pre-moistened sheet. Any of
the first, second or third cleaning members 24, 26 and 27 may be
releasably secured directly to the mop head. In addition, the
second or third cleaning members 26 and 27 may be secured over the
first cleaning member 24.
[0028] In embodiments where the first cleaning member 24 is
constructed of a sponge-like material, a porous material is
typically employed. For example, the first cleaning member may be
constructed of cellulose, polyester, polyether or a blend thereof.
As shown in FIG. 3, the first cleaning member 24 may be releasably
secured to the hinged platen 34 through tiny hooks 37 extending
from the second side 38 of the hinged platen 34. Additionally or
alternatively, slides, clips and other attachments known to those
of skill in the art may be employed to releasably secure the first
cleaning member 24.
[0029] In embodiments where the second and third cleaning members
26 and 27 are constructed of a dry sheet or pre-moistened sheet, a
cellulosic material is typically employed. Natural cellulosics, as
well as synthetics like polyolefins (e.g., polyethylene and
polypropylene), polyester, polyamids and blends thereof are
suitable. Also useful are natural fibers, such as cotton or blends
and those derived from various cellulosic sources. The
pre-moistened sheet may be moistened by the manufacturer or by the
user after purchase.
[0030] The inherent properties of the multiple cleaning members may
vary. The cleaning members may, for example, be disposable,
re-usable and even reversible. Further, the composition of each of
the cleaning members may change, depending on the needs of the
user.
[0031] In accordance with still another aspect of the present
invention, shown in FIG. 3, mop head 22 comprises one or more
securement structures 50 for releasably securing the second and
third cleaning members 26 and 27 thereto. The first cleaning member
24 may also be configured to be releasably secured to the one or
more securement structures 50. The one or more securement
structures 50 are configured to receive and retain the cleaning
members about the mop head 22 during use. One embodiment for
releasably securing the second and third cleaning member 26 and 27
to the mop head 22 is shown in FIG. 3. In this embodiment, four
securement structures 50 are configured to receive and retain the
second and third cleaning members 26 and 27, which comprise flaps
52 that may be tucked into the securement structures 50 on the mop
head 22.
[0032] As illustrated in FIGS. 3 and 4, the four securement
structures 50 of this embodiment are disposed at the corners of the
first side 36 of the hinged platen 34, although these locations may
vary depending upon the size and shape of the mop head 22. The
securement structures 50 may be formed of a flexible material, such
as polyethylene by injection molding, and can be retained within
the first side 36 of the hinged platen 34 by a ridge (not shown)
disposed within the hinged platen 34, which engages a slot (not
shown) disposed on the respective securement structure 50.
[0033] Referring once again to FIG. 3, the flexible material of the
securement structures 50 includes a central slit 54 transverse to
the handle 12 and intersected by a Y-shaped opening 56 defined
along three sides by slits which, like the central slit, extend
through the flexible material. The configuration as well as the
location of the slits on the securement structures 50 may, however,
vary. Under the construction shown in FIG. 3, the Y-shaped opening
56 deflects under finger pressure to allow the flaps 52 of the
second or third cleaning members 26 and 27 to be pushed through the
top surface of the securement structures 50 and into the hinged
platen 34. As the second or third cleaning members 26 and 27 are
pushed through the top surfaces of the securement structures 50,
the slits can engage the cleaning members and hold them in place
about the hinged platen 34. As shown in FIG. 4, the second cleaning
member 26, may be releasably secured over the first cleaning member
24 through use of the securement structures 50.
[0034] Other securement structures may be utilized. Similar to the
first cleaning member 24, the second and third cleaning members 26
and 27 may be releasably secured to the hinged platen 34 or over
the first cleaning member 24 by clips or hooks. In addition, a hook
and loop arrangement, sold under the trademark VELCRO.RTM. and
available from Velcro USA, Inc. of Manchester, N.H. may be
employed. The Velcro may be disposed on the first side 36 of the
hinged platen 34 and on appropriate locations on the second and
third cleaning members 26 and 27.
[0035] In another aspect, use of the different cleaning members
allows one embodiment of the mop of the present invention to be
used in a plurality of different modes. First, by securing the
first cleaning member 24 directly to the hinged platen 34, the mop
10 of the present invention may be used as a wet mop with wringing
capabilities. Second, by securing the second cleaning member 26
over the first cleaning member 24 or directly to the hinged platen
34, the mop 10 of the present invention may be used as a dust mop.
Third, by securing the third cleaning member 27 over the first
cleaning member 24 or directly to the hinged platen 34, the mop 10
of the present invention may be used as a damp mop. This aspect is
convenient for the user, who does not need to purchase separate
mops for separate tasks.
[0036] In other aspects, a cleaning surface such as a scrubber 100,
often utilized for tough ground-in dirt, may be releasably secured
to the mop head 22. As shown in FIG. 5A, one embodiment of scrubber
100 comprises a body 102 and an attachment surface 104, which may
be VELCRO.RTM. or a similar material. The attachment surface 104 is
disposed on the front surface of the scrubber 100. Removable
surface strips, which may be an abrasive scrubbing pad 103, a
polishing pad or a brush, may be attached to the attachment surface
104. The body 102 of the scrubber 100 may be releasably secured to
the mop head 22 or formed as a unitary structure integral with the
mop head 22.
[0037] To releasably secure the scrubber 100 to the mop head 22,
certain features on the support member 28 and the squeeze member 40
may be utilized. As shown in FIGS. 2 and 5B, the support member 28
comprises two cut-outs 29 and 30 and a first pair of apertures 31
and 33 disposed on opposing sides. The cut-outs 29 and 30 are
designed to receive corresponding detent tabs 106 disposed on the
body 102 of the scrubber 100, shown in FIGS. 5A and 5B. Referring
to FIGS. 2 and 5B, the first pair of apertures 31 and 33 of the
support member 28 are designed to receive the pair of opposing arms
42 and 44 of squeeze member 40, which then mate with a second pair
of apertures 108 and 110 within scrubber 100.
[0038] Scrubber 100 may be attached to mop head 22 by pivoting the
opposing plates 46 and 48 of the hinged platen 34 about their
common pivot axis, as shown in FIG. 2. The arms of squeeze member
40 are then manually held together, allowing removal of squeeze
member 40 from the first pair of apertures 31 and 33 of support
member 28. Referring again to FIG. 5B, scrubber 100 is then slid
over support member 28 so that the detent tabs 106 of scrubber 100
mate with the cut-outs 29 and 30 of support member 28 and the first
pair of apertures 31 and 33 are aligned with the second pair of
apertures 108 and 110. Referring now to FIGS. 2 and 5B, opposing
arms 42 and 44 of squeeze member 40 are once again manually held
together and then reinserted back into support member 28. The ends
of the opposing arms 42 and 44 are aligned with the first 31 and 33
and second pair 108 and 110 of apertures and the manual pressure on
squeeze member 40 is released, permitting the ends of the opposing
arms 42 and 44 to enter the first 31 and 33 and second pair 108 and
110 of apertures. Scrubber 100 is thereby releasably secured to
support member 28.
[0039] Removal of scrubber 100 may be accomplished by pivoting the
opposing plates 46 and 48 of the hinged platen 34 about their
common pivot axis A and manually holding the opposing arms 42 and
44 of squeeze member 40 together. Squeeze member 40 is then
removed, and the detent tabs 106 of scrubber are slid off of the
cut-outs 29 and 30 of support member 28.
[0040] In an alternate embodiment, shown in FIG. 6, scrubber 200
and support member 28 are formed as a single component of unitary
construction, which can be releasably secured to mop head 22.
Typically, the single component is constructed of plastic and
fabricated by injection molding.
[0041] In this embodiment, support member 28 itself comprises the
attachment surface 202. As shown in FIG. 6, opposing sidewalls of
support member 28 comprise a pair of opposing apertures 204 and
206. Within support member 28 is a first central channel 208 and
second and third side channels 210 and 212. A spring disposed on
the first side of mop head 22 may be positioned within the first
central channel 208. Support member 28 further comprises an
extension 214, which mates with the lower end 16 of the handle 12
of the mop 10 of the present invention. Extension 214 can be
designed as an interference fit with handle 12 and may be secured
to the mop head 22 through other methods known to those of skill in
the art. Referring now to FIGS. 2 and 6, to releasably secure the
scrubber 200 of this alternate embodiment to the mop head 22, the
opposing arms 42 and 44 of the squeeze member 40 are manually held
together and positioned in the second and third side channels 210
and 212 of support member 28. The ends of the opposing arms 42 and
44 are then positioned within the pair of opposing apertures 204
and 206 of the scrubber 200 and released.
[0042] In addition to the above-identified ways in which the
scrubber and support member are releasably secured to the mop head,
other structures may be employed. For example, a bayonet fitting or
a T-bar, which are known to those of skill in the art are
suitable.
[0043] According to yet another aspect of the present invention,
mop 10 may be adapted to hold and release a fluid, such as a
cleaning solution. As seen in FIGS. 7A and 7B, the handle 12
comprises a portion adapted to hold a fluid. The portion adapted to
hold the fluid is in communication with the lower end 16 of the
handle 12 and may take many forms. For example, the portion may
comprise a removable container associated with the handle or a
container permanently connected to the handle through a tube.
[0044] In select embodiments, the portion is in the form of a
cavity 62 disposed within the handle 12. Use of the cavity 62
eliminates the need for a removable container for holding the
fluid. In turn, this eliminates added costs associated with the
manufacture of the removable container. Further, the absence of the
separate container, makes the mop easier to handle and maneuver and
also facilitates inclusion of a wringing feature, which the
removable container may interfere with when it is disposed on the
handle. Under this construction, the handle may, in certain
embodiments, comprise a substantially uniform cross-section.
[0045] To fill the cavity 62 with fluid, a user may pour the fluid
through an opening 1, disposed on a surface of the handle 12. The
opening may be disposed anywhere on the handle 12, including on its
top surface 7. As shown in FIG. 8, the opening is disposed on the
upper end 14 of the handle 12 and exhibits a threaded outer surface
3, designed to mate with a cap 5 having an opposing threaded inner
surface. A sidewall of the cap may comprise at least one depression
for gripping the cap. After the user grips and removes the cap 5, a
fluid cleaning solution may be poured through opening 1 and into
the handle 12. To check the level of the fluid poured into the
handle 12, a transparent window (not shown) may be disposed on the
handle 12.
[0046] In still another aspect of the present invention, the fluid
is released through the one or more openings 64, 65 and 66 disposed
on the support member 28 or scrubber 100 or 200. As shown in FIGS.
3 and 4, six openings 64, 65 and 66 release the fluid. To maximize
coverage of the fluid over the cleaning surface, the one or more
openings 64, 65 and 66 may be angled in any number of different
directions. For example, as shown in FIG. 4, the openings disposed
on the right side 64 of the mop head 22 may be angled to the right,
the central openings 65 may be unangled and the openings disposed
on the left side 66 of the mop head 22 may be angled to the left.
As those of skill in the art will appreciate, any number of
openings disposed in various arrangement and at various angles may
be employed.
[0047] The fluid is typically released in the form of a spray or
stream. One embodiment of the present invention therefore employs a
valve assembly for releasing the fluid. Generally, the mop of this
embodiment comprises a handle, which includes a portion for holding
the fluid. The handle also includes an opening. The mop further
comprises a valve assembly for releasing the fluid from the opening
in the portion of the handle. The valve assembly itself includes a
valve positioned to cover the opening in the portion of the handle,
which prevents fluid release. To release the fluid, the valve is
movable to a position to uncover the opening.
[0048] A more detailed valve assembly for releasing the fluid is
shown in FIGS. 7A and 7B. FIG. 7A shows the valve assembly in its
closed position. FIG. 7B shows the valve assembly in its open
position. As shown in FIGS. 7A and 7B, the valve assembly comprises
a hollow valve body 68, an annular sleeve 69 surrounding the hollow
valve body 68, a spring 70, a spring retainer 72, a first barbed
fitting 74 and a hook 76 and lever arm 78 both of which are
associated with a rod 71 connected to the second actuator 20. The
hollow valve body 68 may further comprise a flat transverse top
surface 80, a central cavity 82, a first O-ring 84, one or more
apertures 86 and 88, a second O-ring 90 and an annular shoulder
92.
[0049] As shown in FIG. 9, the valve assembly 67 may be connected
to the one or more openings 64, 65 and 66 through a flexible tube
94 associated with the first barbed fitting 74. The opposite end of
the flexible tube 94 may be connected to a second barbed fitting 96
associated with a manifold, on the outer surface of which are
disposed the one or more openings 64, 65 and 66. As shown in FIG.
9, the flexible tube 94 is angled at 45 degrees to achieve the
proper trajectory for releasing the fluid. The flexible tube may,
however, exhibit various other angles and configurations.
[0050] In operation, the valve assembly 67 is activated by the
second actuator 20. As shown in FIGS. 7A and 7B, the second
actuator 20 may be disposed near the upper end 14 of the handle 12
and is associated with the valve assembly 67 through a rod 71
connected to the hook 76. In certain embodiments, the second
actuator 20 may be a trigger or button that, when activated, opens
the valve assembly 67 and releases fluid.
[0051] Before activation of the second actuator 20, the valve
assembly 67 is maintained in a closed position, as shown in FIG.
7A. When the valve assembly is in this condition, the first O-ring
84, working in conjunction with the annular sleeve 69 creates a
seal that prevents fluid from entering the one or more apertures 86
and 88 in the hollow valve body 68. The spring retainer 72 and
spring 70 provide tension to maintain the first O-ring 84 in its
closed position.
[0052] As shown in FIG. 7B, after activation of the second actuator
20, the lever arm 78 is pulled upward, exerting force on the bottom
of the spring retainer 72, thereby compressing the spring 70 and
moving the spring retainer 72 toward the upper end 14 of the handle
12. Movement of the spring retainer 72 in this direction exerts
pressure on the annular shoulder 92, driving the hollow valve body
68 upward and exposing the one or more apertures 86 and 88 to the
fluid. Under these circumstances, fluid enters the hollow valve
body 68 down through the apertures 86 and 88 and flows into the
first barbed fitting 74, through the flexible tube 94 and the
second barbed fitting 96, and out the one or more openings 64, 65
and 66 shown in FIG. 9. As fluid flows through the valve assembly
67, the second O-ring 90 creates a dynamic seal that prevents
leakage of the fluid from the valve assembly.
[0053] The fluid is ultimately released as a spray or stream from
the one or more openings 64, 65 and 66 under the force of gravity.
Thus, to the extent the handle is full, a larger volume of fluid is
released from the one or more openings 64, 65 and 66 through the
valve assembly 67. Of course, even if the handle 12 is not
completely full of fluid, the valve assembly 67 is capable of
releasing fluid from the one or more openings 64, 65 and 66.
[0054] Variations, modifications and other implementations of what
is described herein will occur to those of ordinary skill in the
art without departing from the spirit and scope of the invention.
Accordingly, the invention is in no way limited by the preceding
illustrative description.
