CROSS REFERENCE TO CO-PENDING APPLICATIONS
[0001] This application is a continuation of co-pending U.S. patent
application Ser. No. 09/503,529, filed Feb. 14, 2000, which is
continuation and a continuation-in-part of co-pending application
Ser. No. 09/104,957, filed on Jun. 25, 1998, now U.S. Pat. No.

BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates, in general, to cleaning
apparatus and more specifically, to apparatus for cleaning vehicle
windows.
[0004] 2. Description of the Art
[0005] Various tools are available to clean the exterior surface of
vehicle windows. Such tools typically include a handle and a
perpendicularly oriented cleaning element, such as a wiper blade,
sponge rubber pad and combinations thereof. Water or ammonia based
cleaning fluid is applied to the exterior surface of the vehicle
window and scraped off by the tools to remove debris. Such tools
are easy to use on the exterior surface of vehicle windows since
the exterior surface of the vehicle windows is easily accessible
both to apply cleaning fluid to the windows and to remove the fluid
and debris from the windows.
[0006] However, such tools are ineffective in cleaning the inner
surface of vehicle windows. The extreme angles of the vehicle
windshield and backlight with respect to the dashboard and rear
seat shelf in conjunction with adjacent vehicle components, such as
the rear view mirror, steering wheel and rear, center brake light
housing make it difficult to get the edges of a cleaning tool close
to the extreme lower edges of the windshield and backlight. In
addition, applying fluid, which is typically in the form of a
spray, to the inner surfaces of the windshield and backlight
results in a significant amount of the spray being deposited on the
underlying horizontal surfaces adjacent to the windows, such as the
vehicle dashboard and the rear shelf.
[0007] Thus, the most common implements used to clean the inner
surfaces of vehicle windows are sponges, rags and paper towels.
Manual force is exerted through the user's hands to manually apply
cleaning fluid and/or spray to the inner surface of the windows and
then to manipulate the cleaning element in a back and forth or
circular motion across the surface of the windows. While a user may
be able with a considerable amount of effort to clean most of the
inner surface of the vehicle window, it is still difficult to
completely clean the edges of the window and, more importantly, the
lower edges of a vehicle windshield and backlight.
[0008] A variety of tools have been devised specifically to clean
the inner surfaces of vehicle windows. Such tools are typically
formed of a pad which is connected to an elongated handle. A
cleaning element is attached to one side of the pad by various
means including clips, straps, or hook and pile fasteners. However,
each of these tools is specifically devised for a single type of
cleaning operation, such as scrubbing or drying, but not both.
[0009] While such tools improve the reach of the user and enable
the user to clean the lower edges of vehicle windows, and in
particular, the windshield and backlight, it is believed that
further improvements can be made to such vehicle window cleaning
apparatus to make the cleaning apparatus easier to use, to provide
easily detachable and interchangeable mounting of different shaped
pads or plates to the handle, as well as providing easy replacement
of wet, soiled cleaning elements.
SUMMARY OF THE INVENTION
[0010] The present invention is a cleaning apparatus particularly
suited for cleaning and drying the interior surfaces of vehicle
windows.
[0011] In one aspect, the cleaning apparatus includes a
substantially rigid paddle having first and second opposed
surfaces. The paddle may have a concave bend between opposed ends.
A handle is pivotally connected on one end to the first surface of
the paddle. A cleaning element is removably affixed to the paddle.
The cleaning element includes a first surface mountable in registry
with the second surface of the paddle and side edges disposed over
a peripheral portion of the paddle. Elastic means are provided on
the side edges of the cleaning element for elastically securing the
cleaning element about the paddle.
[0012] Preferably, the cleaning element forms part of a cleaning
system which includes at least two distinct cleaning elements, one
a scrubbing element including a fluid saturable inner layer and,
another, a drying body formed of an absorbent material. The ends of
the side edges of the cleaning element are drawn inward by the
elastic means to form an opening normally smaller than the
periphery of the paddle.
[0013] Hinge means are cooperatively formed on the first surface of
the paddle and the one end of the handle for pivotally connecting
the paddle to the handle. Means are formed on the hinge means for
biasing a pivot pin into a hinge receiver to detachably connect the
paddle to the handle.
[0014] Preferably, the hinge means includes first and second pivot
pins extending coaxially outward from opposed sides of the one end
of the handle. First and second receivers are mounted on the paddle
for receiving the first and second pivot pins, respectively. A
spring biased means is carried on the handle for retractably
biasing one of the first and second pivot pins outward from the
handle.
[0015] An aperture is formed in the end of the handle opening to an
interior chamber in the end of the handle. A slider carries one of
the first and second pivot pins and is movably disposed within the
interior chamber. A spring is engagable with the slider for
normally biasing the slider to a position in which the one of the
first and second pivot pins extends outward through the aperture in
the end of the handle for releasable engagement in one of the first
and second receivers. A projection extends from the slider through
another opening in the handle to facilitate manual movement of the
slider.
[0016] In another aspect of the present invention, the
above-described cleaning apparatus forms part of a cleaning system
which includes a first handle, a plurality of cleaning elements of
the same or different shape, and a plurality of paddles, at least
some of which have a different peripheral shape. The cleaning
elements are easily mountable onto any of the paddles to enable a
clean and dry cleaning element to be used when needed. In addition,
each of the paddles is quickly and easily attachable and detachable
from the handle for ease in using the cleaning system of the
present invention.
[0017] In another aspect, the cleaning apparatus and cleaning
system of the present invention includes a second handle having a
generally inverted U-shape with opposed lower ends extending
oppositely outward from each other. The handle ends are releasably
mountable in a second pair of receivers formed on each paddle. The
paddles receive cleaning elements as in the above-described aspects
of the invention.
[0018] Generally, the second handle is of one-piece construction
with lower S-shaped side legs extending between an upper hand
engagement portion and the ends. The S-shape side legs are is
configured to absorb forces exerted by the user on the handle
during movement of the paddle. The second set receivers may also be
formed on the same paddles in the first aspect of the invention.
This enables either the first or second handles to be employed with
any paddle thereby further enhancing the interchangeability of the
various components of the cleaning system of the present
invention.
[0019] The cleaning apparatus of the present invention affords
numerous advantages over prior cleaning apparatus devised for
cleaning the interior surfaces of vehicle windows. The present
cleaning apparatus enables a plurality of different shaped paddles
and attached scrubbing and drying elements to be detachably mounted
on one handle for use in practically any vehicle window cleaning
application. The cleaning apparatus lends itself to use as part of
a cleaning system formed of one or more handles, a plurality of
different shaped paddles, and releasably attachable cleaning
elements. The cleaning elements are easily mountable and removable
from the paddles and the paddles are easily attachable and
detachable to either handle. The present cleaning apparatus enables
a user, for example, to easily reach the lower edges of the
interior surface of vehicle windows adjacent to the vehicle dash
board or rear backlight despite the extreme angles of such windows
with respect to interior vehicle surfaces and the adjacent rear
view mirror, steering wheel or rear center brake light assembly
housing.
[0020] The present cleaning apparatus is also usable without a
handle. In such an application, the user need only grab the two
enlarged receivers on the paddles for the first handle to
manipulate the paddle and attached cleaning element over a surface.
The different cleaning elements are easily attachable and removable
from the paddle thereby minimizing the total time required for each
cleaning operation as a scrubbing element and one or more drying
elements can be quickly and easily mounted on a paddle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0034] Referring now to the drawing, and to FIGS. 1-5 in
particular, there is depicted a first embodiment of a cleaning
apparatus 10 constructed in accordance with the teachings of the
present invention. It will be understood that although the
following description of the use of the cleaning apparatus 10 in
cleaning and drying the interior surfaces of vehicle windows, the
cleaning apparatus 10 may also be applied in a variety of other
cleaning applications, such as to clean and dry the exterior
surface of the vehicle windows, house or building windows, mirrors,
or practically any surface that requires the use of a cleaning
fluid and its removable from the surface being cleaned.
[0035] In general, the cleaning apparatus 10, includes a paddle 12,
a handle 14, and a drying element 16.
[0036] As shown in one embodiment in FIGS. 1-4, the paddle 12 is
formed of a generally planar plate 20 having one of a number of
different configurations or sizes. The plate 20 is preferably
formed of a lightweight material, with a suitable plastic material
being preferred. However, other materials, such as metal, wood,
composites, etc., may also be employed.
[0037] The plate 20 has a generally rectangular or possibly square
configuration with four exterior side edges each denoted by
reference number 22. Rounded corners or radii are formed at the
juncture of each of two side edges 22. The plate 20 is also formed
with a first or rear surface 50 and a second, opposed, front
surface 52.
[0038] The plate 20 may be provided in two different sizes, such as
a small size and a large size. By example only, a small size plate
20 may have dimensions of 5".times.7". The larger plate 20 may have
dimensions of 7".times.9". It will be understood that the plate 20
may also be formed with a square configuration of equal length side
edges 22 and with other square or rectangular dimensions as needed
for a particular cleaning application.
[0039] The paddle 12 may also be formed in other configurations for
drying different shaped windows or portions of a vehicle window. As
shown in FIG. 5, a plate 30 has a general oval shape with maximum
dimensions of 7".times.9" for a large oval shaped plate 30 or
5".times.7" for a smaller oval shaped plate 30. All of the exterior
surface or side edges of the paddle 12 are smoothly curved without
any sharp projections or corners.
[0040] FIGS. 6A and 6B depict plate 34 which may also be used to
form the paddle 12 of a cleaning embodiment of the apparatus 10. In
this embodiment, the plate 34 has a first flat side edge 36 which
smoothly merges into two generally perpendicularly extending side
edges 38 and 40. The side edges 38 and 40 have an end portion 42
and 44, respectively, which tapers inwardly toward each other
thereby narrowing the width of the plate 34 at a second end 46
opposite from the side edge 36. The tapered portions 42 and 44
extend to a smoothly rounded apex or second end 46.
[0041] As shown in FIGS. 1 and 2, the paddle 12, regardless of its
plate configuration 20, 30 or 34, may have a generally planar
shape. A slight concave bend may also be formed in any of these
plates 20, 30 or 34.
[0042] Referring now to FIGS. 1-3, the handle 14 of the cleaning
apparatus 10 may take one of a variety of different shapes to
provide a convenient gripping surface even when wet. Thus, by
example, the handle 14, shown in FIGS. 1 and 2, is formed of a
lightweight material, such as a somewhat rigid, although flexible
and slightly bendable plastic. The handle 14 is formed of an
elongated member 56 of one of at least two distinct lengths and
having a first end 58 and an opposed second end 60. The elongated
member 56 extends generally planarly between the first and second
ends 58 and 60. Although the member 56 may have a constant
cross-section and a constant width dimension from end to end, in
order to provide a more easily grippable surface 14, the member 56
is formed with a first enlargement 62 at the first end 58. The
opposed side edges of the member 56 taper inwardly from the first
enlargement 62 to a smaller width intermediate portion 64 before
tapering outwardly to a second enlarged portion 66 adjacent the
second end. At least a portion of the first enlargement 62 and the
intermediate portion 64 of the member 56 may be formed with a rough
or contoured exterior surface, such as a series of serrated, spaced
ridges or projections as shown in FIGS. 1 and 2, to provide an
easily grippable surface even when wet.
[0043] As shown in FIGS. 2 and 3, the side edges of the second
enlarged portion 66 taper smoothly outward from the intermediate
portion 64 and terminate in opposed first and second side edges 68
and 70, adjacent the second end 60 of the member 56.
[0044] The cleaning apparatus 10 also includes means for mounting
any of the plates 20, 30 and 34, one at a time, to the handle 14.
Preferably, the mounting means includes means for detachably
mounting the plates 20, 30 and 34 to the handle 14. More
preferably, means are provided for pivotally and detachably
mounting the plates 20, 30 and 34 to the handle 14.
[0045] According to a preferred embodiment of the present invention
shown more clearly in FIGS. 3A and 3B, the mounting means includes
a pivot pin 72 mounted or unitarily formed on the first side edge
68 of the member 56. The opposite or second side edge 70 is formed
with an aperture 73 which opens to an interior chamber 74 in the
second enlarged portion 66 of the member 56 adjacent to the second
end 60. An opening or cut out 76 in the exterior surface of the
handle 14 communicates with the interior chamber 74.
[0046] A spring biased pin assembly 80 includes a slider 82 having
a generally cylindrical cross section. The slider 82 is formed with
a reduced diameter first end in the form of a circular sleeve 84. A
shoulder 85 on the slider 82 form a seat for a biasing spring, such
as a coil spring 100 which also engages one end of the interior
chamber 74.
[0047] The opposed end of the slider 82 is formed as a pivot pin 88
having essentially the same shape as the pin 72 mounted on the side
edge 68 of the handle 14. A notch or recess 90 is formed in the
slider 82 adjacent to the pin 88 at one end of the slider 82. The
recess 90 forms a resilient, movable arm 92 along one side of the
slider 82. The free end of the arm 92 is formed in a projection or
catch 83 which extends beyond the exterior surface of the adjacent
portion of the slider 82 in a normal, biased position shown in FIG.
3A.
[0048] In assembling and mounting the spring biased pin assembly 80
as shown in FIGS. 3A and 3B, the spring 100 is mounted over the
sleeve 84 on the slider 82. The spring biased pin assembly 80 is
inserted spring first through the aperture 73 into interior chamber
74 in the handle member 56.
[0049] The arm 92 is depressed by the user toward the opposite side
of the slider 82 to enable the outer end of the projection or catch
83 to be inserted through the aperture 73 in the handle 14. The end
of the catch 83 is angled to aid in downward movement of the catch
83 upon engagement with the end 70.
[0050] Continued insertion forces are exerted on the end of the pin
88 of the slider 82 until the projection 83 passes the interior
edge of the opening 76 in the enlarged end portion 66 of the handle
14. The resilient nature of the arm 92 enables the projection 83 to
snap outward, as shown in FIG. 3B, to lock the spring biased pin
assembly 80 within the interior chamber 74 of the handle 14 as
shown in FIG. 3B. The spring 100 is compressed a slight amount to
exert a spring force against the slider 82 to maintain the slider
82 in a position in which the projection 88 normally engages one
edge of the opening 76 in the handle 14.
[0051] As shown in FIGS. 1 and 2, the pins 72 and 88 are co-axially
aligned and form part of hinge means which are rotatably mountable
in opposed hinge members 102 and 104 as shown in FIG. 1. Each of
the hinge members or receivers 102 and 104 are preferably unitarily
formed as part of the first or rear surface 50 of the paddle 12.
Since the paddle 12 is preferably formed of a plastic, the hinge
members 102 and 104 may be unitarily molded as part of the paddle
12.
[0052] Each of the hinge members 102 and 104 are in the form of
solid bodies which are unitarily formed as part of the plate 20 and
project upwardly from the first rear surface 50 of the plate 20. As
shown in FIGS. 4 and 5, each of the hinge members 102 and 104 is
formed with an inner face opposing the inner face of the opposed
hinge member in a smoothly curved or arcuate shaped outer surface
extending toward the adjacent side edge 22. Alternately, the hinge
members 102 and 104 may be simple flanges projecting
perpendicularly from the first rear surface 50 of the plate 20,
with each flange having an aperture for receiving the pivot pins 72
and 88.
[0053] Thus, the internal bores 106 and 108, respectively, receive
the pivot pins 88 and 72, respectively, on the handle 14 to
pivotally couple the plates 20, 30 and 34 to the handle 14 and
enable substantially 180.degree. pivotal movement of the handle 14
relative to the plates 20, 30 and 34.
[0054] Each plate embodiment of the paddle 12 is coupled to the
handle 14 by pushing the projection 83 on the slider 82 away from
the adjacent side edge 70 of the handle member 56 to retract the
end 88 of the slider 82 inwardly within the interior chamber 74 in
the second enlarged portion 66 of the handle member 56 to enable
the second side edge 70 to be disposed adjacent to the inner
surface of the second hinge member 102, it being understood that
the opposed pivot pin 72 has already been inserted into the bore
108 in the second hinge member 104. Release of the projection 83
allows the spring 100 to move the slider 82 away from the spring
stop 91 and to urge the second pivot pin 88 outwardly through the
aperture 73 in the second side edge 70 of the handle member 56 and
into the bore 106 in the hinge member 102.
[0055] The projection or catch 83 is positioned along the length of
the slider 82 from the second pivot pin end 88 to enable the pivot
pin 88 to be completely retracted within the second end 70 of the
handle 14 when the projection 83 engages the far end of the opening
76. Release of the moving force on the projection 83 enables the
spring 100 to move the slider 82 in an opposite direction until an
opposite edge of the projection 83 engages the edge of the opening
76 and the pivot pin 88 projects exteriorly of the second end 70 of
the handle 14.
[0056] A first drying element embodiment of the cleaning element 16
which is removably mountable on the paddle 12 is shown in FIG. 4.
In this embodiment, the drying element is in the form of a pliable
body 110 sized to releasably mount about the plate 20 of the first
embodiment of the paddle 12. Thus, the body 110 has a first major
surface 112 which is disposable adjacent a second front surface 52
of the plate 20, a continuous side edge 114 extending from the
first major surface 112, and a peripheral edge 116 surrounding an
open end opposite the first surface 112. The peripheral edge 116
may be stitched to prevent unraveling or separation of the fibers
forming in the body 110. Preferably, the body 110 is formed of an
absorbent material, such as cotton, etc.
[0057] Elastic means 118 in the form of an elastic band is stitched
or otherwise attached to the peripheral edge 116 of the body 110 to
provide an elastic force for closing the peripheral edge 116 to a
small open diameter to thereby securely, yet releasably mount the
body 110 about the paddle 12. At the same time, the elastic means
118 allows the body 110 to be easily removed from the paddle 12 and
replaced with a clean, dry body 110 when necessary.
[0058] It will be understood that the body 110 may be provided in
different sizes to conform to the shape and size of the large or
small plates 20 described above.
[0059] A second embodiment of a body 120 usable as the drying
element is shown in FIG. 5 and includes a first major surface 122,
a continuous side edge 124 and a peripheral edge 126. Elastic means
128 are secured to the peripheral edge 126. Preferably, the
peripheral edge 126 and the adjacent side edge 124 are formed or
cut to a generally oval shape to enable the body 120 to conform to
the shape of the oval plate 30.
[0060] Yet another body 130, shown in FIGS. 6A and 6B, may be used
as the cleaning element 16 for the plate 34. Like the other bodies
110 and 120, the body 130 is formed of a first, generally planar
surface 132, a side edge 134 which terminates in continuous
peripheral edge 136 surrounding an opening, and elastic means 138
secured to the peripheral edge 136. The peripheral edge 136 and the
side edge 134 are preferably formed in the shape of the plate 34 to
enable the body 130 to be removably mounted about and to conform to
the shape of the plate 34. As shown in FIG. 6A, an absorbent layer
or pad 140 of substantially the same shape as the plate 34 is
interposed between a major surface of the plate 34 and the first
major surface 132 of the body 130 to provide fluid absorbent
features. The pad 140 can be loosely interposed between the plate
34 and the body 130 or fixed on the plate 34 by adhesive or other
suitable means. The body 130, in this embodiment, is preferably
formed of a mesh or rough material to act as a scrubbing surface in
conjunction with a fluid filled absorbent layer 140 which dispenses
fluid during the scrubbing operation. Thus, the body 130 and
absorbent layer 140 function as a scrubbing element to apply
cleaning fluid to a window and, with suitable scrubbing movement,
to simultaneously loosen dirt and other debris from the window.
[0061] The various drying and cleaning bodies 110, 120 and 130
shown in FIGS. 4-6 may be used to perform a variety of cleaning or
drying tasks. Any of the bodies 110 and 120 may be used merely as a
dusting cloth to remove dust from a vehicle window or other
interior vehicle surface. Further, the body 130 shown in FIG. 6 and
its associated plate 34 with the rounded end 46 and interior
absorbent layer 140 is ideally suited to act as a sponge and
scrubbing surface in applying cleaning fluid or water to the
interior surface of a vehicle window and scrubbing or removing
debris stuck on a window.
[0062] Once the absorbent layer 140 is wetted with the cleaning
fluid, the handle 14 of the cleaning apparatus 10 is grasped by one
hand of the user and then moved adjacent to the window until the
body 130, contacts the interior surface of the window. The cleaning
element 10 is then moved in any motion, such as back and forth,
sideways, circular or combinations thereof to apply the cleaning
fluid to the entire interior surface of the window and to remove
any debris stuck on the window. The body 130 and plate 34 are then
removed from the handle 14 by simply reversing the insertion
operation of the spring biased pin assembly 80 as described above
to detach the plate 34 and the from the handle 14. Specifically,
the user exerts a sliding force on the projection 83 to the right,
in the orientation shown in FIG. 3B, urging the slider 82 against
the force of the spring 100 until the pin 88 on the slider 82
disengages from the associated hinge 102. This enables the paddle
12 and the handle 14 to be separated from each other. One of the
other bodies 110 or 120 and its, associated plate 20 or 30,
respectively, is then attached to the handle 14 as described above.
The body 110 or 120 is then brought into engagement with the window
and again moved in any fashion across the entire surface of the
window to dry the previously applied cleaning fluid and remove any
loose debris from the window.
[0063] If, at any time, the body 110 or 120 becomes saturated with
cleaning fluid or accumulates a significant amount of dirt or other
debris, the user may simply remove the body 110 or 120 from the
associated paddle 12 and then mount a clean, dry body 110 or 120 on
the paddle 12 to continue with the cleaning operation.
[0064] In a further use of the cleaning apparatus described above,
any of the paddles, such as paddle 34 shown in FIG. 6A, can be
employed without the handle 14 by a user merely grasp the enlarged
receivers 102 and 104 with his or her hand to manipulate the paddle
and the cleaning element attached thereto over a surface to be
cleaned.
[0065] Referring now to FIGS. 7-9, there is depicted another aspect
of the present cleaning apparatus which may form part of an overall
cleaning system constructed in accordance with the present
invention. As shown in FIGS. 7, 8, and 9, the cleaning apparatus
160 includes a paddle 162 which is depicted as having the same
overall shape as the paddle 34 shown in FIG. 6A. It will be
understood that the paddle 162 is shown by example only as any of
the preceding paddles may be employed in the cleaning apparatus
160. In addition, the cleaning elements 16, described above, may
also be employed over the paddle 162.
[0066] In this aspect, the cleaning apparatus 160 includes a handle
164 having a generally inverted U-shape. The handle 164 is
preferably formed of a flexible plastic.
[0067] The handle 164 has a strip-like form including an upper
portion in the form of a generally planar top wall 166 which is
adapted to be grasped by the hand of the user to manipulate the
cleaning apparatus 160 over a surface to be cleaned, a pair of
depending side legs 168 and 170 and a pair of outwardly extending
lower ends 172 and 174 which project outwardly from the side legs
168 and 170, respectively. The ends 172 and 174 are flat or planar
in shape and are adapted to releasably engage a pair of receivers
176 and 178 formed on one surface of the paddle 162. The receivers
176 and 178 are aligned with each other, preferably along the
longitudinal centerline of the paddle 162. By way of example only,
each receiver 176 and 178 is formed of an inverted U-shaped tab
having a central portion spaced from the adjoining surface of the
paddle 162 to form an aperture there between sized to releasably
receive one of the lower ends 172 and 174 of the handle 164.
[0068] The side legs 168 and 170 of the handle 164 have a smoothly
curved, arcuate, S-shape to provide a degree of springiness to the
handle 164. In the exemplified shape, each of the side legs 168 and
170 initially curves outward from one end of the top wall 166 of
the handle 164 in a first curved portion 180 before curving inward
toward the opposed side leg along portion 182. The side legs 168
and 170 then reverse direction and smoothly curve along portion 184
to a junction with the lower ends 172 and 174, respectively.
[0069] For added strength, the portions 180 and 184 have a greater
thickness than the adjoining top wall 166, surface portion 182 or
the lower ends 172 and 174 as the portions 180 and 184 will
encounter the greatest amount of flexure during movement of the
cleaning apparatus 160.
[0070] Optional, elongated, laterally extending tabs 190 project
outward from opposed side edges of the surface 184 on each side leg
168 and 170. The tabs 190 provide a convenient surface for
inserting and removing the lower ends 172 and 174 from the
receivers 176 and 178, respectively.
[0071] The present invention provides a cleaning apparatus 160a as
shown in FIG. 10. The cleaning apparatus 160a includes a paddle
162a, a first handle 14a having first and second opposed ends, and
a second handle 164a having opposed ends. The first and second
pivot pins 72a and 72b extend coaxially from the opposite side of
the second end of the handle 14a. The paddle 162a includes first
and second receivers 102a and 104a. Each of the receivers 102a and
104a are capable of receiving one of the first and second pivot
pins 72a and 72b for pivotally connecting the first handle 14a to
the paddle 162a. The paddle 162a also includes third and fourth
receivers 176a and 178a for receiving one of the ends of the second
handle 164a. One of the first and second handles 14a and 164a may
be removably mounted on the paddle 162a at one time. The cleaning
apparatus 160a also includes a cleaning element 16a removably
mountable over the paddle 162a.
[0072] Thus, there has been disclosed a unique cleaning apparatus
and cleaning system for cleaning and drying the interior surfaces
of windows and, particularly, vehicle windows which is easy to use,
is capable of scrubbing and drying all of the window surfaces,
including the lower edges adjacent the vehicle dash board and rear
shelf, has easily detachably mounted paddles and scrubbing and
drying elements enabling different shaped paddles and fresh, dry
cleaning elements to be easily attached to the handle for scrubbing
and drying various portions of or different shaped windows as well
as enabling the cleaning elements to be easily removed when wet or
soiled and a new element applied to the paddle.
