Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of Australian Patent
Application No. 2004205176, filed Aug. 23, 2004. The application is
incorporated herein by reference in its entirety.
FIELD OF THE INVENTION
[0002] This invention is directed to an attachment that can be
attached to a carpet wand to make the carpet wand particularly
suitable for use on hard floors. The attachment can be quickly and
easily attached to almost any type of carpet wand and can also be
quickly detached. The attachment can also be used to increase the
size of a normal carpet wand to make the carpet wand more efficient
on carpets.
BACKGROUND ART
[0003] A carpet wand forms part of an apparatus that is used to
steam clean carpets. The apparatus typically comprises a motor, a
long flexible vacuum hose, and a carpet wand that is attached to
the end of the hose. The carpet wand typically comprises a steel
handle. The lower end of the steel handle contains a head. The head
is formed with an elongate transverse slot. The motor generates a
strong vacuum to cause particulate matter/water to be sucked
through the transverse slot and through the hose. A water tank
forms part of the apparatus and a heater is provided to heat the
water. A smaller solution hose conveys hot water/cleaning agent to
the head. The head of the carpet wand contains one or more nozzles
in front of the transverse slot and hot water passes through these
nozzles under pressure. The hot water loosens dirt in the carpets
and the water/dirt is sucked through the slot and through the
vacuum hose. It is common for a surfactant or other additive to be
mixed with the water.
[0004] There are various different designs of the carpet wand and
particularly, there are different head sizes.
[0005] While the carpet wand is efficient for steam cleaning
carpets, it is not very efficient in cleaning hard floors such as
wooden floors, cork floors, lino floors etc.
[0006] It is known to provide a purpose built wand for hard floors.
This wand is sometimes known as a vacuum squeegee. The wand is
again attached to a vacuum hose and hot water is provided under
pressure fitted to jets inside the squeegee head.
[0007] When cleaning the floors in a houselbuilding, it is very
common for the floors to be a combination of carpets and hard
floors. Conventionally, it has been necessary to have two wands,
one being a carpet wand, and the other being a wand for hard
floors.
[0008] There would therefore be an advantage if it were possible to
provide an attachment that could be attached to a carpet wand to
make the carpet wand suitable for use on hard floor such that it
would no longer be necessary to provide a completely separate wand
for hard floors.
[0009] It will be clearly understood that, if a prior art
publication is referred to herein, this reference does not
constitute an admission that the publication forms part of the
common general knowledge in the art in Australia or in any other
country.
SUMMARY OF THE INVENTION
[0010] An attachment for a carpet wand is provided that can make
the carpet wand suitable for use on hard floors and which may
provide a useful or commercial choice.
[0011] In one form, the invention resides in an attachment for a
carpet wand, the attachment being attachable to the head of a
carpet wand to make the carpet wand suitable for use on hard
floors.
[0012] Suitably, the attachment comprises an elongate body.
[0013] The elongate body may have a length which is approximately
the same length as the width of the carpet head or longer.
Typically, the elongate body will have a length of between 20-80
centimetres.
[0014] The elongate body may be made of any suitable material
including metal such as aluminium, steel, metal alloys and the
like. The elongate body may also be made of plastics, composite
materials and the like and it is not considered that the invention
should be limited to the material from which the elongate body is
made.
[0015] The elongate body typically comprises a top wall and a
bottom wall. The top wall may be provided with an elongate slot or
opening which is adapted to cooperate with the elongate slot on the
head of the carpet wand. It is preferred that the elongate slot on
the elongate body has a length which is sufficient to accommodate
almost all commercial versions of carpet wands such that the
attachment can be used on different carpet wands. The
opening/elongate slot may be in communication with the outside air
to provide an air flow through the opening/slot when vacuum is
applied.
[0016] Attachment means may be provided to attach the attachment to
the carpet wand. It is considered that any suitable type of
attachment means could be used. For instance, the attachment means
may comprise a clip, a clamp, a fastener, adhesive, straps and the
like. In a particular embodiment, the attachment means comprises an
attachment plate that can releasably lock the attachment to the
head of the carpet wand. Suitably, a pair of attachment means is
provided.
[0017] The elongate body typically comprises an opening in the
bottom wall. The opening may comprise an elongate slot which
cooperates with the opening/elongate slot on the top wall. The
opening in the bottom wall preferably comprises an elongate slot
that extends substantially along the length of the elongate
body.
[0018] The attachment may comprise at least one nozzle/jet through
which hot water or other fluid can pass preferably under pressure.
Suitably, a plurality of nozzles/jets is provided. The nozzles/jets
may be provided on the elongate body to direct fluid under pressure
towards the ground, and may be connected to a manifold or like
member.
[0019] The, or each, nozzle/jet preferably communicates with a hose
that is attached to the attachment. The hose can be attached to the
supply of hot water that forms part of the carpet cleaning
apparatus as described above.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0030] Referring initially to FIGS. 1-3, these illustrate a
conventional carpet cleaning wand head. Referring initially to FIG.
1, there is illustrated a carpet wand which is made of metal and
which comprises a hollow handle 10 and a head 11.
[0031] FIG. 2 is an inverted view of head 11. Head 11 contains a
transverse elongate slot 12 which communicates with handle 10 such
that when a strong suction is applied to handle 10, slot 12 becomes
a strong suction slot. Handle 10 also supports a smaller hot water
hose 12. Hot water hose 12 couples to a pair of spray nozzles 13,
14 which are best illustrated in FIG. 3. Splashguards 15 are
provided on head 11 to prevent overspray. This arrangement is
entirely conventional.
[0032] FIGS. 4-5 illustrates a top view and a bottom view of an
attachment that can be attached to head 11 to convert the carpet
wand into a hard floor cleaning tool. FIG. 6 and FIG. 7 illustrate
the attachment fitted to the head.
[0033] Referring initially to FIG. 4, the attachment 16 comprises
an elongate body 17 which has a top wall 18 containing an elongate
slot 19. Slot 19 has a length which is at least long enough to hold
slot 12 in head 11, such that slot 12 can fit within or against
slot 19 (see FIG. 7). It is preferred that the slot 19 has a length
to accommodate most types of wand heads, such that the attachment
is a "universal type" attachment. Once head 11 has been attached
such that slot 12 fits within slot 19, the head is clamped to
attachment 16 by an attachment means which in the particular
embodiment comprises a pair of angled plate members 20 which can be
turned from the position illustrated in FIG. 4 to the position
illustrated in FIG. 7. Members 20 can be tightened using wing nuts
21 to clamp the attachment 16 firmly to head 11.
[0034] Seals (not illustrated) can be used to ensure that slot 19
seals against slot 12 to minimise any loss of vacuum. The seals may
comprise elongate rubber strips.
[0035] Slot 19 contains a portion 22 (best illustrated in FIG. 4)
to accommodate the edge of an overspray shield 15 on the carpet
wand head (see FIGS. 2 and 7).
[0036] A plurality of nozzles form part of attachment 16. The
nozzles 23 extend from a manifold 24 which communicates with hose
25. Hot water passing through hose 25 will therefore pass through
manifold 24 and through each of nozzles 23 to direct hot water to
the floor. The manifold 24 is detachable from the elongate body and
can be attached to either the leading or trailing side of the
elongate body. When used in the trailing position, water is
connected by the flexible hose in the same manner as in use in the
leading position. When the operator wishes to use the floor tool in
the trailing position and needs to use water from the existing
nozzles on the wand head and from the nozzles attached to the
manifold which is now attached in the trailing position, a T type
joiner needs to be fitted at the end of the hot water solution hose
where it connects to the wand nozzles.
[0037] Best illustrated in FIG. 6 is hose 25 which is coupled to
the hot water hose 12 that forms part of the conventional carpet
wand. Specifically, one of the nozzles 13 of the conventional
carpet wand is removed and hose 25 is connected to the opening to
supply hot water to the attachment. Thus, it is not necessary to
provide a separate supply of hot water as the attachment will use
the hot water which is conventionally supplied to the carpet
wand.
[0038] Referring to FIG. 5, there is illustrated a bottom view of
attachment 16. An elongate slot 26 extends substantially along the
length of the bottom of attachment 16 and communicates with slot
19.
[0039] Grooves are provided along the bottom of attachment 16 and
various side pieces can be fitted into the grooves, these
comprising rubber strips, nylon brush strips, stainless steel
carpet cleaning lips, etc. In the particular embodiment, there is
illustrated rubber strips 27 on each side of slot 26.
[0040] In use, the attachment is fitted to the conventional head 11
of a carpet wand. Vacuum is then turned on and hot water is
provided through hose 12 such that hot water sprays through nozzles
23 and onto the hard surface (e.g. wooden floor, lino floor, etc).
The water is sprayed onto the floor under pressure ahead of
attachment 16. As the attachment is moved over the floor, the floor
will be cleaned and then the vacuum will suck up the water/dirt via
slots 26 and 19 (see FIG. 9). When not required, the attachment can
be easily removed.
[0041] The rubber strips are manufactured from a non-marking
substance and are moulded with grooves along the strip. When the
rubber strips are moved over the floor surface, water is sucked
through the grooves and into the vacuum slot and then to the waste
area by the vacuum hose. When the rubber strips are inserted for
use on hard floor, timber, vinyl and like material, the rubber
strips acts as a buffer between the metal of the elongate body and
the floor. This prevents any damage to the floor surface. Nylon
brush strips can be used for scrubbing and cleaning and for uneven
surfaces. Stainless steel lips can be used for carpet cleaning.
[0042] Side shields 30 (see FIG. 8) can be fitted to each side of
the attachment to prevent overspray.
[0043] The attachment can fit to various different commercial
brands of carpet wands and it is not necessary to damage or to
modify the existing carpet wand in any way.
[0044] The attachment can be used to clean vinyl and ceramic tiles,
timber, stone, slate, concrete and any other hard surface.
[0045] However, the attachment can also be used to clean carpets by
attaching stainless steel carpet cleaning lips to replace rubber
strips 27 thereby providing an increase in the cleaning width of
the carpet wand. Therefore, the attachment should not be limited
only to cleaning hard floors.
[0046] Throughout the specification and the claims (if present),
unless the context requires otherwise, the term "comprise", or
variations such as "comprises" or "comprising", will be understood
to apply the inclusion of the stated integer or group of integers
but not the exclusion of any other integer or group of
integers.
[0047] Throughout the specification and claims (if present), unless
the context requires otherwise, the term "substantially" or "about"
will be understood to not be limited to the value for the range
qualified by the terms.
[0048] It should be appreciated that various other changes and
modifications can be made to any embodiment described without
departing from the spirit and scope of the invention.
