DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now in detail to the drawing, a bucket 10, in accordance
with a preferred embodiment of the present invention, is shown in
operative association with a conventional wringer apparatus 12 and
is adapted to be mounted upon a transportable chassis or carriage
14. As will hereinafter be described in detail, the bucket 10 is
adapted to contain, for example, cleaning liquids or the like that
may be used in connection with conventional cleaning utensils, such
as a mop or the like, which may have the liquids extricated
therefrom by means of the apparatus 12.
The apparatus 12 may be of any conventional construction, such as
that shown in U. S. Pat. No. 2,199,906, issued May 7, 1940, the
descriptive portion of which patent is incorporated by reference
herein. Generally speaking, the wringer apparatus 12 comprises a
frame 16 including a pair of laterally spaced side plates 18 and 20
which define a mop head receiving receptacle 22 therebetween.
Disposed within the receptacle 22 is a pressure-applying means 24
that is actuable by a suitable handle 26 for exerting a compressive
force against a mop head in order to effect extraction of any fluid
therein. As seen in FIG. 4, the side plates 18, 20 are formed with
a pair of downwardly extending projections 28 which define recesses
30 adapted to nestingly receive the rim portion of the bucket 10 in
a manner such that the receptacle 22 hangs downwardly into the
interior of bucket 10, as is well known in the art. Disposed
adjacent the lower ends of the side plates 18, 20 is a generally
laterally extending bearing element or strap 32 formed with a
central outwardly bowed arcuate portion 33 which is adapted to
function in a manner hereinafter to be described in lending
stability to the wringer apparatus 12 during operation thereof.
Referring now in detail to the consturction of the bucket 10, as
best seen in FIGS. 1 and 2, the bucket 10 comprises a generally
horizontally extending bottom section 34 and a pair of generally
flat or planar upstanding, laterally spaced side wall sections 36
and 38. Extending between the side wall sections 36, 38 are forward
and rearward end wall sections 40 and 42, respectively, which are
integrally connected to the marginal edges of the side wall
sections 36, 38 by means of upstanding angularly disposed integral
corner sections 44. The bucket 10 is of a monolithic or one-piece
molded construction and is preferably fabricated of a molded
natural or synthetic, high-strength resinous or elastomeric
material, such as polyvinylchloride (PVC), polystyrene, molded
plastic, fiberglass, hard rubber or other suitable material which
lends itself to conventional molding techniques. As best seen in
FIG. 3, the upper marginal edge of the sections 36-44 are formed
with a continuous outwardly turned, integral, generally inverted
U-shaped rim portion 46 which functions in a rigidifying capacity
in order to strengthen the bucket 10.
With reference to FIGS. 1 and 2, the end wall sections 40 and 42
are formed with centrally disposed, upwardly extending, generally
outwardly convex arcuate portions 48 and 50, respectively, which
are of a generally complementary configuration with respect to the
arcuate shape of the curved portion 33 of the bearing element 32.
That is, the portion 33 and portions 48, 50 are defined as lying on
a peripheral sector of a common imaginary circle. Additionally, the
end wall sections 40, 42 comprise a pair of genrally flat or planar
portions 52, 54 and 56, 58, respectively, which are arranged
adjacent the opposite sides of the curved portions 48 and 50,
respectively. It may be noted that the lateral spacing between
portions 52, 54 and 56, 58 is approximately equal to the lateral
spacing between the side plates 18, 20 of the wringer apparatus
12.
Mounted adjacent the upper ends of each of the flat portions 52-58
is a generally U-shaped wear plate 60 (see FIG. 3), the plates 60
preferably being fabricated of a suitable relatively hard material,
such as a corrosion resistant metal, and being fixedly secured to
the bucket 10 by means of suitable screws, bolts, rivets, or the
like 62 which extend through the plate 60 and the upper marginal
edge of the bucket 10, as best seen in FIG. 3. The bucket 10 may be
and preferably is provided with a suitable handle 64 which may be
of any suitable configuration, such as U-shaped, and have the
opposite ends thereof secured to the side wall sections 36, 38 by
suitable securing means representatively designated by the numeral
66.
The bucket chassis 14 may be of any suitable construction, such as
that shown in U. S. Pat. application, Ser. No. 112,618, filed Feb.
4, 1971, which is assigned to the assignee of the present
application and the subject matter of which is incorporated by
reference herein. Preferably, the chassis 14 comprises four
outwardly projecting arm or leg sections, generally designated 68,
the outer ends of which are secured to the bucket 10 by means of
fastening plates 70 that engage suitable recessed areas 72 at the
lowermost ends of the corner sections 40 of the bucket 10. Suitable
means such as caster wheels or the like 74 are provided on the
outer ends of the arms 68 so as to provide for convenient rolling
transportation of the entire assemblage consisting of the bucket
10, wringer apparatus 12, and chassis 14.
In use, the wringer apparatus 12 is operatively mounted upon either
the forward or rearward end wall section 40, 42 of the bucket 10 in
a manner such that the recesses 30 nestingly receive the flat
portions 52, 54 or 56, 58, resulting in the uppermost portions of
the recesses 30 engaging or bearing upon the wear plates 60, as
best seen in FIGS. 2 and 4. When the wringer apparatus 12 is
operatively mounted upon the bucket 10, the curved portion 33 of
the bearing element 32 contiguously engages the inner periphery of
the adjacent curved portion 48 or 50, whereby to provide for
surface-to-surface contact therebetween. With this arrangement, the
wringer apparatus 12 is supported at two laterally spaced points
adjacent the upper end thereof, i.e., at each of the associated
wear plates 60, and along a laterally extending surface comprising
the confronting surfaces of the bearing element 32 and inner
surface of the adjacent end wall section 40 or 42. Accordingly,
maximum stability is provided so as to positively prevent any
relative movement between the wringer apparatus 12 and the bucket
10 during a liquid extracting or wringing operation. It will be
appreciated that while the bucket 10 of the present invention is
illustrated as having the apparatus 12 mounted upon the rearward
end wall section 42 thereof, said apparatus 12 could just as well
be mounted on the opposite or forward end wall section 48, or
alternatively, two wringer devices could be mounted, one at each
end of the bucket 10.
It will be seen from the foregoing that the present invention
provides a novel bucket construction which preferably, although not
necessarily, will find extremely useful application in connection
with conventional mop-type wringer apparatus. A particular feature
of the present invention resides in the fact that the bucket 10 may
be economically manufactured by means of well known molding or
casting techniques, and by virtue of being fabricated of a
polymeric or plastic material, will be highly resistant to damage
due to scratching, denting, or the like. Additionally, the bucket
10 may be fabricated of a material which is highly resistant to
corrosive attack by strong cleaning chemicals commonly used in
connection therewith. Yet another feature of the present invention
may be seen from the fact that the lateral side wall sections 36,
38 are spaced laterally outwardly from the opposite sides of the
wringer apparatus 12 so as to prevent any possible interference
between the actuating mechanism of the apparatus 12 and the bucket
10.
While it will be apparent that the preferred embodiment illustrated
herein is well calculated to fulfill the objects above stated, it
will be appreciated that the present invention is susceptible to
modification, variation and change without departing from the scope
of the invention.
