Cleaning devices convertible between floor and wall treatment
configurations
Abstract
Cleaning devices are disclosed which can rapidly be reconfigured
from an elongated mop, to an intermediate size upper wall cleaner,
to a shorter window cleaner. A common aerosol canister support and
actuator and a common cleaning head are used. The device can be
triggered by either a trigger on the support, or by a remote
trigger on a separate handle. An extension wand can connect the
remote handle to the canister support. Linkages between the handle,
wand and support are via a quick disconnect coupler allowing rapid
disassembly and assembly while permitting triggering components to
act through the joint created by the coupler.

Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation-in-part of both U.S.
application Ser. No. 10/386,009 filed on Mar. 10, 2003 and U.S.
application Ser. No. 10/385,982 filed on Mar. 10, 2003.
STATEMENT OF FEDERALLY SPONSORED RESEARCH/DEVELOPMENT
[0002] Not applicable.
FIELD OF THE INVENTION
[0003] The present invention relates to cleaning devices that
dispense cleaning agents such as floor, tile or window cleaning
compositions. More particularly it provides devices that can be
converted between an elongated configuration (such as would be used
for floor mopping) and at least one shortened, lighter weight
configuration (such as might be used for cleaning windows, walls
and other surfaces).
BACKGROUND OF THE INVENTION
[0004] Cleaning devices have been developed that dispense a
cleaning chemical onto the surface being cleaned. Some such devices
supply the chemical through a gravity feed mechanism. However,
gravity fed devices are not well suited for cleaning vertical
surfaces such as windows or bathroom walls.
[0005] Other such devices rely on an electrical pump to pump the
liquid to a spray system. See e.g. U.S. patent application
publication 2001/0046407. Such electrical pumping systems increase
the weight of the device, making it awkward for use on a vertical
surface, increase its cost, and require recharging or replacement
of batteries.
[0006] Other devices dispense cleaning chemicals in the form of
aerosol sprays. These devices use an aerosol canister containing
the cleaning chemical mixed with a gas propellant. The canister is
mounted to a canister holder, which in turn is mounted on a pole or
the like between a cleaning head on the device and a handle. The
handle is typically long enough so that the cleaning head can be
extended up to reach high ceilings or out to reach underneath
furniture. Some of these devices provide remote actuation via
trigger located near the remote handle. Examples of prior art
aerosol cleaning systems of this general type are disclosed in U.S.
Pat. Nos. 3,679,319; 3,794,217; 4,789,084; 4,886,191; 5,099,539 and
5,779,155.
[0007] The Grab-it Go Mop of S.C. Johnson, Inc. is another example
of a remotely triggerable aerosol spray cleaning device. It has a
handle, an extension pole, a canister holder, and a cleaning head.
However, the apparatus is designed so that once it is assembled for
the first time the handle will be essentially permanently attached
to the part that it is connected to (normally an extension pole),
and the extension pole will be essentially permanently attached to
the canister holder. This helps insure proper transmission of
trigger movement to the actuator for the canister.
[0008] While such an aerosol system does have significant
advantages, the existing systems are not well suited for arraying
the aerosol outlet at different distances from the handle for
different cleaning applications. Thus, a device of this type
optimized from the standpoint of weight and length for floor
cleaning is not optimal for cleaning closer surfaces such as
windows.
[0009] Vacuum cleaners are used for cleaning floors and other
surfaces. They are often provided with multiple different cleaning
heads and one or more extension wands that can be positioned
between the main hose and the cleaning head (depending on the
cleaning application of interest). The wands can easily be
assembled or disassembled from the other parts of the device.
However, vacuum cleaners do not dispense an aerosol spray, and thus
do not require the triggering mechanisms needed to remotely actuate
such a spray. In particular, they do not solve the problem of how
to pass triggering mechanisms through extension wands that may only
optionally be present.
[0010] U.S. Pat. No. 3,713,744 disclosed a dispenser system in
which the cleaning head was capable of adjustment so as to render
the device somewhat more suitable for cleaning walls or floors
(alternatively). While this was of some value with respect to the
lower portions of walls, it still did not provide optimal
flexibility for reconfiguring the device, particularly with respect
to the length of the assembly.
[0011] Hence, a need still exists for improved dispenser systems
that permit the length of the device to be readily modified, while
still retaining remote triggering capability.
SUMMARY OF THE INVENTION
[0012] In one aspect the invention provides a cleaning apparatus
having a handle linked to a first trigger; a canister holder having
a section for mounting an aerosol can, a grip section, and a second
trigger; an extension pole removably linkable to the canister
holder adjacent one end of the extension pole and to the handle
adjacent an opposite end of the extension pole; and a cleaning head
linked to the canister holder. The apparatus is suitable to be
assembled in a first alternative configuration where the extension
wand is so linked to the handle and canister holder and movement of
the first trigger can move the actuator, and then the apparatus can
readily be reconfigured into an alternative configuration where
neither the extension wand, nor handle are linked to the canister
holder, but movement of the second trigger can still move the
actuator.
[0013] By "readily" throughout this application we mean that the
parts need not be broken or require the application of tools to
cause the reconfiguration, and that further within less than ten
minutes (preferably less than a minute, even more preferably within
less than thirty seconds) the parts can be reconfigured by an
average adult consumer who has previously been instructed as to the
means of reassembly.
[0014] In a preferred form of this embodiment the apparatus is also
such that the apparatus can be readily reconfigured from the
alternative configuration into a third configuration where the
handle is linked to the canister holder and the extension wand is
not linked to the canister holder or handle, where movement of the
first trigger can move the actuator.
[0015] In another aspect the invention provides a cleaning
apparatus that has a handle linked to a trigger, a canister holder
having an actuator capable of actuating an aerosol can (if an
aerosol can is mounted to the canister holder), an extension pole
removably linkable to the canister holder adjacent one end of the
extension pole and to the handle adjacent an opposite end of the
extension pole, and a cleaning head linked to the canister holder.
The apparatus can be assembled in a first configuration where the
extension wand is so linked to the handle and canister holder and
movement of the trigger can move the actuator. The apparatus can
then be readily reconfigured in an alternative configuration where
the extension wand is not linked to either the handle or canister
holder (it is left out of the device), but the handle is linked to
the canister holder and movement of the trigger can still move the
actuator.
[0016] In preferred forms the handle (and also the lower end of the
extension wand) are formed with a first type of quick disconnect
coupling element. An upper portion of the extension wand and an
upper portion of the canister holder are formed with a second type
of quick disconnect coupling element. By "quick" we mean that
within less than one minute (preferably less than ten seconds) the
parts at a joint can be disconnected by an average adult consumer
who has previously been instructed as to the means of
disassembly.
[0017] The first type of quick disconnect coupling element can be a
male member, and the second type of quick disconnect coupling
element can be a female member with a radially/transversely
releasable latch. Both the first type and second type of quick
disconnect coupling elements can have an axial bore which forms
part of a passageway for receiving a sliding member coupled to the
trigger and actuator.
[0018] In another form of the invention the extension wand can have
an axial socket, and at least one of the canister holder or handle
can have a stem sized to fit into the socket. The extension wand
can be releasably retained in the socket by a spring biased latch
where the latch has a ramped surface engagable with a catch surface
on the stem and a push button suitable for moving the latch in
opposition to the spring. The latch can surround a periphery of the
stem when the stem is positioned in the socket.
[0019] In yet another aspect of the invention there can be an
aerosol can positioned on the canister housing in a fashion where
the actuator can be moved by the trigger to cause a dispensing of a
chemical in the aerosol can.
[0020] The preferred chemical is a cleaning chemical suitable for
floors, tiles or windows. An example of such chemical would be a
Windex aerosol spray sold by S.C. Johnson & Son, Inc. However,
the nature of the chemical is not critical, and even could be just
water.
[0021] Yet another attribute of the invention is to provide a
latching apparatus for releasably linking two pole segments
together, regardless of the function the apparatus. This apparatus
can comprise a first pole having a male stem with a radial catch
surface, and a second pole having a female socket suitable to
receive the male stem in telescoping fashion. The second pole can
also have a radial opening adjacent the socket for receiving a
transversely movable latch. The latch is spring biased in an
outward direction, and is in the form of a slab having a central
through bore suitable to receive the stem.
[0022] The latch is suitable to catch on the radial catch surface
when the latch is in one position. It is also suitable to permit
the stem to pass along the central through bore when the latch is
in a second position.
[0023] The present invention thus provides improved cleaning
devices that are quickly and easily adjustable in length (and to
some extend weight) while retaining the ability of at least one
remote trigger to operate the spray canister. The system is
designed to be used with a cleaning head system that can also be
optimized for the intended application.
[0024] These and other advantages of the invention will be apparent
from the detailed description which follows and the drawings. It
should be understood that the following merely provides preferred
embodiments of the invention. The claims should be looked to in
order to understand the full scope of the invention.

[0034] FIG. 10 is a cross-sectional view taken along line 10-10 of
FIG. 1 showing the triggering mechanism of the handle, and how it

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0035] The preferred form of the present invention provides an
assembly capable of being configured in a long form (with upper
handle, extension wand, canister holder, long aerosol can, and
cleaning head), a short form (with neither upper handle or
extension wand, but with canister holder, short aerosol can, and
cleaning head), or an intermediate form (with upper handle, no
extension wand, canister holder, short or long aerosol can, and
cleaning head). The long form would be best suited for mopping
floors. The short form would be best suited for cleaning counter
tops and/or windows. The intermediate form would be best suited for
cleaning surfaces of vertical walls that are near the ceiling.
[0036] In all cases, a trigger is provided to remotely activate the
aerosol can. In some cases the trigger is on the handle. In others
it is on the canister holder. It can also be on both. A primary
benefit of the device is to permit the remote operation of an
aerosol can at varying lengths away from the triggering handle,
with the consumer being able to make quick adjustments depending on
the particular cleaning application of interest.
[0037] While the entire cleaning device will be described generally
here, certain aspects of the device are more specifically described
in co-pending U.S. applications Ser. Nos. 10/385,982 and
10/386,009, both filed on Mar. 10, 2003, both of which are hereby
incorporated by reference as though fully set forth herein.
[0038] With reference to FIGS. 1 and 3, a cleaning device 10
includes as major components a remote handle assembly 12, an
extension wand 14, a canister holder 16 having its own handle
assembly 18 and also an adjustable can retainer assembly 20. The
retainer assembly is suitable to alternatively hold an aerosol
canister 22A or 22B. The canister contains a selected cleaning
chemical. The assembly also has a cleaning head 24.
[0039] The canister 22 is aligned and mounted to the support
housing 16 by a "ski-boot" type connection having a toe stop 26, a
T-rail (not shown) and a heel assembly 28 slidable along the rail.
A locking tab (not shown) formed in the T-rail clicks into one of
two receivers at two preset adjustment locations to alternatively
hold full-size (FIG. 1-22A) or compact (FIG. 2-22B) canister.
[0040] The heel assembly 28 has a spring biased latch (not shown)
that engages an inside surface of a rim 30 at the bottom of the
canister 22A/22B. The latch is operated by a thumb operated release
lever 32, which when depressed clears the latch from the canister
22. Releasing the release lever 32 resets the latch so that the
canister can be removed and another canister can be snapped in
place. This aspect of the device is described in significantly
greater detail in U.S. application Ser. No. 10/386,009 incorporated
by reference above.
[0041] One end of the support housing 16 connects to the cleaning
head 24 by a quick disconnect coupler 34 mounted to a pivot mount
36 formed as an integral part of a backing plate 38 supporting a
compressible pad 40. The pad 40 can be a substrate for mounting a
cleaning cloth or dusting sheet, or it may be (or mount) a sponge
or scrubber pad. The plate 38 and pad 40 could be replaced by a
bristled brush head, wiper blade or any other suitable cleaning
implement desired.
[0042] The cleaning head coupler 34 allows for plug in type quick
connection and disconnection of the cleaning head 24 to the
canister support housing 16 and permits it to swivel about a swivel
axis 42 and independently pivot about a pivot axis 44 lying in a
plane perpendicular to that of the swivel axis 42. The cleaning
head coupler 34 includes a swivel lockout feature having slidable
locking member 46 that engages and prevents rotation of a swivel
part 48 of the coupler 34. This aspect of the device is described
in significantly more detail in U.S. application Ser. No.
10/385,982 incorporated by reference above.
[0043] The remote handle assembly 12 is connectable to the end of
the support housing 16 opposite the cleaning head 24 by the
extension wand 14. The grip assembly 12 includes a hollow
(two-piece) plastic pistol grip housing defining a handle 50 and a
pivotally mounted trigger 52 operable by an index finger when
gripping the handle 50. A hollow shaft extension 54 has a stem end
56 which plugs into a quick connect coupler 58 at one end of the
extension wand 14. Similarly, an opposite, stem end 60 of the
extension wand 14 plugs into another quick connect coupler 62 at
the end of the support housing 16.
[0044] The stem ends 56 and 60 are preferably separate plastic
pieces fit into the ends of the shaft extension 54 and the
extension wand 14. The stem ends 56 and 60 are identical as are the
couplers 58 and 62. Thus, if desired, the extension wand 14 can be
removed from the assembly so that the remote grip assembly 12 can
be directly connected to the canister support housing 16 to create
an intermediate length assembly (see FIG. 4).
[0045] As shown in FIG. 2, the remote grip assembly 12 and the
extension wand 14 can be completely removed from the assembly, with
the device then being operated by a separate trigger 64 and held by
a handle section 66 of the support housing 16. The trigger can be
reached once the shorter canister 22B replaces the longer canister
22A. Also note that, as shown in FIG. 1, the longer canister 22A
serves to block the trigger 64 such that when the device is stored
as an assembled mop, accidental discharge of cleaner by items
banging against the trigger 64 in a crowded closet is
inhibited.
[0046] As noted above, FIG. 1 shows the cleaning device 10 of the
present invention fully assembled in a mop-like configuration for
cleaning floors or ceilings. FIG. 2 shows the cleaning device 10 as
configured for window cleaning and cleaning other close-up vertical
surfaces such as bathroom tiles. FIG. 4 shows how the device could
be used when cleaning near the top of walls.
[0047] Apart from the flexibility of reconfiguration, another
important aspect of the invention is the quick disconnect coupling
system. There is, as shown in FIGS. 5-7, a male element 56 on the
handle, a male element 60 on the extension wand, a female element
58 on the extension wand, and a female element 62 on the canister
housing. Of course, the positioning of the male and female elements
could be reversed.
[0048] In an especially preferred form of the invention, the male
elements 56 and 60 are identical to each other, and the female
elements 58 and 62 are identical to each other. Thus, the element
56 can be directly used with the element 62 when the wand 14 is
deleted from the assembly. When the wand is used, the element 56
can fit in the element 58 while the element 60 is used with the
element 62.
[0049] Coupler 62 includes an open-ended socket insert 70 which
fits into an open end of the container support housing 16. The
socket insert 70 defines a generally cylindrical passageway 72
between the extension wand and/or handle and the actuator extending
from toe stop 26. As best seen in FIG. 6, the socket insert 70 has
a transverse/radial slot 74 sized to fit a latch ring 76. The latch
ring 76 is generally ring-shaped with flat sides and defines a
unitary ramp 78 and push button 80.
[0050] The latch ring 76 can slide within the slot 74 and is biased
against such movement by a spring 82 mounted on a boss 84
underneath the push button 80. The latch ring 76 is sized to fit
around the periphery of the stem end 56 when fully inserted into
the coupler 62. As the stem end 56 is inserted into the coupler 62
the ramp 78 cams the latch ring 76 to compress the spring 82 until
the ramp 78 fits into a recess 86 in the stem end 56 and engages a
catch surface 88 (see FIG. 8). This arrangement allows the
components to be quickly snapped together and also resists axial
separation of the stem end 56 from the coupler 62 until the push
button 82 is depressed and the extension wand 14 is pulled from the
support housing 16. The socket insert 70 and the latch ring 76 are
held in the support housing 16 by a retainer collar 90 that snaps
onto tabs 92 at the end of the support housings 16.
[0051] Referring now to FIGS. 3 and 8-10, internal to the handle
assembly 12, extension wand 14 and the support housing 16 is a
movable actuator assembly linking triggers 52 and 64 to the valve
of the canister 22 for spraying cleaner via the actuator associated
with toe stop 26. The actuator assembly includes slidable core
members, such as members 94 and 96, at least in each of the handle
assembly 12, extension wand 14 and canister support housing 16.
These members slide in response to movement of either of the
triggers 52 and 64 and in turn pivot an actuator lever which
protrudes though an opening in the toe stop 26 to operate the valve
of the canister 22.
[0052] Assemblies for remotely actuating an actuator with a remote
handle trigger are described in U.S. Ser. No. 10/384,877, filed on
Mar. 7, 2003 and U.S. Ser. No. 09/951,632, filed on Sep. 14, 2001,
which are hereby incorporated by reference.
[0053] Referring to FIGS. 1 and 8-10, the grip assembly 12, the
extension wand 14 and the main body 16 housing have sliding core
members, such as 94 and 96. The sliding members in the grip
assembly 12 and the wand extension 14 are sized to extend through
passageways, such as passageway 98, to the tips of the respective
stem ends 56 and 60 such that when the associated trigger 52 or 64
is depressed they protrude from the stem ends 56 and 60 in contact
with enlarged plunger ends, such as plunger end 100, of the
adjacent sliding member in the mating part (as shown in FIG. 9).
The large plunger ends help ensure transfer of motion between
adjacent sliding members in the event they become slightly axially
misaligned during operation. When trigger 52 is depressed it slides
the sliding members in the remote grip assembly 12 downwardly which
abut sliding members 94 and 96 in the respective extension wand 14
and main body 16, which will contact a trip leg 120 of trigger 64
in turn abutting another sliding member 122 in the main body 16.
This in turn pivots an actuator lever 124, a working end of which
moves components of a canister valve 126.
[0054] In particular, the actuator lever 124 contacts (when either
trigger 52 or 64 is depressed) a free end 126 of a lever arm 128
hinged at the opposite end to a cylindrical wall 130 of an overcap
110 mounted to the canister 22. The lever arm 128 moves a hollow
valve stem 132 into abutment with the internal components of the
canister valve 126 to dispense the cleaner. Although not shown, the
lever arm 128 has a nozzle adapted to provide a fan-shaped spray at
a predetermined angle as measured from the top of the overcap
66.
[0055] A user generally utilizes the cleaning device like any
conventional poled or hand-held cleaning aerosol device. When the
user desires to spray cleaner onto the surface being cleaned, the
user simply squeezes either trigger 52 or 64, which pivots a hinged
part of the over cap 110 on the canister 22 which in turn moves the
actuator 124 to open the canister valve and spray out cleaner near
the cleaning head. When the trigger 52 or 64 is released, springs
(not shown) bias the actuator assembly to its original,
non-activated position (shown in FIG. 10), which allows the
canister valve to close and stop spraying.
[0056] The present invention thus provides an improved cleaning
device that is quickly and easily adjustable in length and remotely
triggerable. The quick disconnect coupler allows for movement of
sliding inner core members to couple the remote trigger to the
canister, while at the same time providing a simple plug in
connection of the wand or the grip assembly to the canister support
or between two or more segments of a longer extension wand
assembly. The mating parts simply snap together by virtue of the
spring biased latch and can be disassembled by simply depressing a
button on the latch and separating the parts.
[0057] It should be appreciated that merely preferred embodiments
of the invention have been described above. However, many
modifications and variations to this preferred embodiment will be
apparent to those skilled in the art, which will be within the
spirit and scope of the invention, and as such the invention should
not be limited to the described embodiment. Accordingly, to
ascertain the full scope of the invention, the following claims
should be referenced.
INDUSTRIAL APPLICABILITY
[0058] The invention provides improved remotely triggerable
cleaning devices that can be rapidly reconfigured to modify length
or weight.
