Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] The present application claims the benefit of and priority
to U.S. Provisional Patent Application No. 61/518,683, filed May 9,
2011 and titled "Multipurpose Cleaning Device," the content of
which is incorporated herein by reference for all purposes.
BACKGROUND
[0002] Tiled surfaces are spaced apart when installed and these
spaces are typically filled with grout. The grout surface is
usually recessed from the tile surface, making the grout surface
difficult to clean when using conventional floor cleaning tools
that use broad sweeping motions such as a mop or sponge. The
recessed location of the grout tends to collect dirt, which
requires frequent cleaning and the rough texture of the grout
requires increased pressure to clean. Moreover, grout in baths or
showers, or other high humidity environments, is susceptible to
mold and mildew which are difficult to clean. Scrubbing brushes aid
the cleaning of grout but are very tedious in function, as each
grout line has to be scrubbed individually. The spacing between
grout lines is a function of tile size, which can vary greatly. A
brush with multiple heads at a fixed width may only be useful for
one specific application due to this variance in spacing between
grout lines.

DETAILED DESCRIPTION
[0015] A cleaning device including a rigid body that allows
multiple adjustable attachments for cleaning applications is
provided herein. The cleaning device may be a rigid body cleaning
device that can accommodate a variety of attachments to clean a
variety of surfaces including grout between tiled surfaces.
[0016] The cleaning device includes attachments mounted to a rigid
assembly. The rigid assembly is of solid construction and includes
three, structurally integrated parts: a handle, a flange and a
head. The head forms a mounting track, which is in part also formed
by the flange, for several brush head assemblies. The top of the
head incorporates a raised rib along its lengthwise axis to provide
rigidity to the head and to assist in the transfer of energy from
the handle to the head through the flange. The raised rib also
defines a forward and rear track concave notch. The raised rib
creates a track along the head that allows the brush head
assemblies to be mounted at any desired spacing along the head as
well as allowing the attachment of other accessories to the
head.
[0017] A cleaning device with multiple brush heads allows several
lines of grout to be cleaned simultaneously. Customizable spacing
of brush heads allows for the cleaning of varying widths of grout
lines. Attachments such as a squeegee, sponge, or brush allow the
device to be used for multiple purposes including removing cleanser
film from grout and tile which may be left after cleaning adjacent
grout lines.
[0018] It is understood that while a preferred embodiment of a
cleaning device is illustrated and described below, it is not
limited to the specific form or arrangement of parts and/or design
elements herein described and shown.
[0019] Referring to FIG. 1, FIG. 2A and FIG. 2B, the cleaning
device 10 includes a lengthwise handle 20, a flange 30, and a head
40. All three components are contiguous and structurally
integrated, creating a single rigid structure. Therefore, the
handle 20 is coupled to the flange 30 and the flange 30 is coupled
to the head 40. The flange 30 connects the handle 20 with the head
40. The handle 20 is a hollow tube designed to be comfortable for
gripping and may have a threaded aperture, which may allow
connections to elongate the handle 20. The head 40 includes a
raised rib 41 and a support section 42 that allows attachments to
slide along the entire length of the head 40. The raised rib 41 may
be common to the head 40 and the flange 30. The support section 42
may be a support tract. The raised rib 41 extends along the top of
the head 40 running the lengthwise axis of the head 40. The support
section 42 forms two tracks along the lengthwise axis of the head
40; the forward track 421 and the rear track 422. As shown, both
the forward track 421 and the rear track 422 are convex. The raised
rib 41 also forms two concave notches with the top surface of the
support section 42; the forward track notch 423 and the rear track
notch 424. The dimension of the forward track 421, which is the
segment of the head 40 in front of the raised rib 41, may be equal
or unequal to the dimension of the rear track 422, which is the
segment of the head 40 behind the raised rib 41. If the forward
track 421 and rear track 422 are of unequal dimensions, the
asymmetrical design may ensure that all attachments may be placed
onto the head 40 in one direction, ensuring the correct orientation
of the attachments onto the head 40. The forward track notch 423
and the rear track notch 424 may dictate the orientation of
attachments by creating a shape that accommodates a corresponding
shape on the attachment. If the orientation of attachments does not
matter for cleaning purposes, the forward track 421 and rear track
422 may be of equal dimensions and the forward track notch 423 and
the rear track notch 424 may be of symmetrical shape.
[0020] The cleaning device 10 may be made from a variety of
materials, including, but not limited to, plastic, aluminum,
stainless steel, titanium, wood or graphite. Other materials may be
used if desired. The size of the cleaning device 10 may vary and
particularly the lengthwise dimension of the head 40 may be shorted
or elongated for a variety of applications of the cleaning
device.
[0021] Referring to FIG. 1, the embodiment of the cleaning device
10 shown includes multiple identical brush assemblies 50 mounted on
the head 40. With additional reference to FIG. 3, the brush
assembly 50 will now be discussed in detail. The brush assembly 50
is an attachment. It will be appreciated that the attachment may be
removably coupled to the support section 42, shown in FIG. 2B.
Specifically, in some embodiments two or more attachments may be
removably coupled to the support section. The brush assembly 50
includes a brush body 51, comprised of a forward flange 511 and a
rear flange 512. The brush body 51 is a single-piece brush body in
the depicted embodiment. The forward flange 511 may be mated with
the forward track 421, shown in FIG. 2B. Likewise, the rear flange
512 may be mated with the rear track 422, shown in FIG. 2B. The two
flanges create a "C" shaped brush body 51. The "C" shape of the
brush body 51 creates a support track 515 to slide the brush
assembly 50 onto the head 40. The "C" shape of the brush body 51
may limit the movement of the brush assembly 50 in relationship to
the head 40 when in use by allowing the forward flange 511 and the
rear flange 512 to hug the around the support section 42. The
dimensions of the forward flange 511 of the brush assembly and the
rear flange 512 of the brush assembly correspond to the dimensions
of the forward track 421 of the head 40 and the rear track 422 of
the head, respectively, which may be equal or not equal. This
correspondence may provide a tight fit between the brush assemblies
50 and the head 40 which may substantially reduce and in some cases
eliminate movement of the brush assemblies 50 during operation and
may also ensure the brush assemblies 50 are oriented onto the head
40 in the correct direction if desired. The forward flange end 513
and the rear flange end 514 of the brush body 51 may be convex and
may correspond conversely with the shape of the forward track notch
423 and the rear track notch 424 of the support section 42. This
correspondence may provide a tight fit between the brush assemblies
50 and the support section 42 and may also provide a desired
orientation of the brush assemblies 50 onto the head 40. The
forward flange 511 of the brush body 51 houses a threaded hole in
which a thumbscrew 53 may be engaged. The thumbscrew 53 may be
configured to secure the brush assembly 50 or other suitable
attachment at a fixed location along the head 40, shown in FIG. 2A,
and at a fixed distance relative to other attachments. Thus, a user
may tighten the thumbscrew to fix the relative position of the
brush assembly to the head or loosen the thumbscrew to enable
adjustment of the relative position of the brush assembly. In this
way, the thumbscrew may be selectively adjustable by a user of the
cleaning device.
[0022] The bottom of the brush body 51 contains several rows of
bristles 52 which may be oriented in a direction efficient for use.
The bristles 52 may be referred to as grout-cleaning bristles.
However, the bristles may be used to clean a variety of surfaces,
if desired.
[0023] As depicted in FIG. 3, brush body support track 515 is
designed to encompass support section 42 and slide along the entire
length of support section 42. Brush body 51 may be constructed of a
rigid plastic, nevertheless, a plastic with a modulus of elasticity
which allows a slightly under-dimensioned brush body support track
515 to be marginally opened by the user of cleaning device 10 upon
installation onto support section 42, thereby biasing brush body
support track 515 with a compressive force on support section 42
which may secure the fit between support section 42 and brush body
support track 515 and which may substantially reduce play, and
therefore wear and tear, between these surfaces. Such a sign may be
desirable as thumbscrew 53, while fixing brush assembly 50 to
support section 42, provides force to substantially prevent the
brush body 51 from pivoting in relationship to head 40 during
vigorous use of cleaning device 10.
[0024] The brush assemblies 50 are mounted to the head 40 of the
cleaning device 10 via sliding onto the track of the head 40 such
that they remain parallel to one another and may be spaced at any
desired interval along the entire lengthwise axis of the head 40.
Thumbscrews 53 that are engaged at the top of each brush assembly
50 may be advanced to press against the head 40 and lock the brush
assembly 50 in any desired location along the head 40. Although
thumbscrews 53 are used in this embodiment, other means of locking
the brush assemblies 50 onto the head 40 may be used such as quick
release cams or levers, etc. An embodiment of the cleaning device
10, shown in FIG. 1, includes a group of six brush assemblies 50
mounted onto the head 40. However the cleaning device may include
more, or fewer, brush assemblies 50 if desired. The structure and
operation of each brush assembly 50 is identical. Therefore, where
one brush assembly 50 is described, this description applies to
each of the assemblies. However, in other embodiments the structure
of the brush assemblies may vary.
[0025] Referring to FIG. 4, an alternative embodiment may use a
squeegee attachment 60 mounted to the head 40, shown in FIG. 2A,
for the use of removing excess water from surfaces. The length of
the attachment body 61 is equal to the length of the head 40 of the
cleaning device 10, in the depicted embodiment. However, other
attachment body lengths have been contemplated. The squeegee may be
inserted into a squeegee track 65 on the front of the squeegee
attachment 60 allowing for easy replacement. The attachment body 61
slides along the track of the head 40 through a set of flanges
611/612 on either side of the top of the attachment body 61. The
forward flange 62 is equipped with a threaded hold for a thumbscrew
64 to advance onto the head 40 and lock the attachment into place
on the head 40 and consequently attaching to the cleaning device
10.
[0026] A contiguous support section 42 along the entire length of
head 40 permits a brush assembly 50 to be placed and secured
anywhere along support section 42, and a brush assembly 50 may be
installed or removed from either end of head 40. Moreover,
contiguous support section 42 also permits alternative cleaning
device attachments to be mounted to head 40, and in particular
squeegee attachment 60 is depicted in FIG. 4 and sponge 70 in FIG.
5. In other embodiments, two or more squeegee attachments or
sponges may be removably coupled to the contiguous support section
42.
[0027] Other alternate embodiments may include a sponge 70 in FIG.
5, or a continuous brush attachment mounted to the rigid body in a
similar manner as the embodiments described above. The sponge 70
may be referred to as a grout-cleaning sponge. However, the sponge
may be used to clean a variety of surface, if desired. It is also
possible to have an embodiment that permanently mounts brush
assemblies or other apparatus to the support track.
[0028] The cleaning device may also include a long handle screwed
into the threaded handle of the rigid body, elongating the handle
and extended the reach of the device.
[0029] While specific embodiments of the cleaning device have been
described in detail, it would be appreciated by those skilled in
the art that there is modification and alterations that would be
developed in light of the overall teaching of the disclosure.
Accordingly, the particular arrangements disclosed are meant to be
illustrative only and not limiting as to the scope of the
invention.
