FIELD OF THE INVENTION
The present invention is generally related to ?oor cleaning
machines. More speci?cally, one embodiment of the present
invention is a ?oor cleaning machine that includes a steering
mechanism With a ?exible telescoping portion. The ?exible
telescoping portion accommodates movement ofa housing to
Which it is associated to alloW easy access to interior portions
of the device.
BACKGROUND OF THE INVENTION
Floor cleaning machines generally of the Walk behind or
ride on variety are comprised of a chassis supported by a
plurality of Wheels, one of Which is steerable to control the
path of the machine. The chassis also accommodates the
cleaning apparatus, such as a brush(s), a squeegee, a bur
nisher, for example (hereinafter “cleaning apparatus”). The
steerable Wheel is interconnected to a steering Wheel, or joy
stick, by Way of a steering mechanism comprised of various
gears. The chassis also supports tanks used to hold Water
cleaning ?uids and spent cleaning ?uids suctioned from the
?oor. The majority of the components associated With the
cleaning machine are surrounded by at least one housing
Whichprotects the internal components from the environment
and protects individuals that are Working around the machine
from touching the often hot internal components. As ?oor
cleaning machines are often used in tight spaces, such as
bathrooms and hallWays, it is desirable to make ?oor cleaning
machines as compact as possible.
It is also desirable to provide ?oor cleaning machines that
alloW for easy access to internal componentry for mainte
nance and repair thereof. Unfortunately, the desire for easy
access is often at odds With the desire to provide a compact
apparatus. Speci?cally, prior art machines are constructed in
such a Way that the internal volume thereof is minimized,
providing a compact machine, but leaving virtually no easy
access to internal componentry. In order to address this dis
advantage, some prior art machines utiliZe removable seg
ments to the housing that cover internal components. Often,
hoWever, external components, such as steering Wheels, con
trol panels, external storage tanks, etc., must be removed prior
to removal ofthese housing segments. Removal ofthe exter
nal componentry as Well as the housing segments technology
is time consuming, costly, and increases the chance that the
machine Will be damaged or a component ofthe machine Will
be lost.
Thus there is a long felt need to provide a ?oor cleaning
machine that is compact yet alloWs easy access to the internal
components thereof Without requiring disassembly of por
tions ofthe ?oor cleaning machine. The folloWing disclosure
describes an improved ?oor cleaning machine that includes a
plurality ofmovable housings that are associated With exter
nal components that do not require removal prior to removal
or movement of the housings. Thus a highly compact, yet
serviceable ?oor cleaning machine is provided, as Will be
described beloW.
SUMMARY OF THE INVENTION
It is one aspect ofthe embodiment ofthe present invention
to provide a ?oor cleaning machine that includes a chassis
that is supported by a plurality of Wheels, one of Which is

steerable. The steerable Wheel is associated With a steering
mechanism that is also associated With the chassis. The steer
ing mechanism generally may employ a plurality ofgears that
transfer rotational inputs from a steering Wheel to rotation of
the gears that ultimately alter the angle ofthe steerable Wheel
or Wheels. The chassis also supports ?oor cleaning apparatus,
such as brushes, squeegees, spray noZZles, etc., all of Which
are described in, for example, US. Pat. No. 7,533,435 entitled
“Floor Treatment Apparatus”, Which is incorporated by ref
erence in its entirety herein.
The internal components of the ?oor cleaning machine,
such as pumps, vacuums, storage tanks, tubes, electrical hard
Ware, batteries, etc. are stored Within a housing, Which gen
erally de?nes the outer envelope ofthe ?oor cleaning device.
The housing directs cooling air around certain components of
the ?oor cleaning device, protects individuals from gaining
accidental access to haZardous areas of the ?oor cleaning
device and protects internal components ofthe ?oor cleaning
device from environmental damage. In one embodiment of
the present invention, the housing may be comprised of a
primary housing directly interconnected to the chassis. The
primary housing may have a plurality ofremovable segments
that alloW selective access to the interior ofthe ?oor cleaning
device or may be of one piece construction that surrounds all
internal components of the ?oor cleaning machine. The pri
mary housing may be removable from the chassis in any
number ofWays knoWn in the art. A front housing is rotatably
interconnected to at least one of the primary housing or the
chassis and is thus capable of transitioning aWay from the
primary housing to alloW access to internal components cov
ered thereby, both from above and from the front ofthe ?oor
cleaningmachine. Finally, arearhousing is providedthatmay
also be rotatably interconnected to the chassis and/or primary
housing. The housing segment is also selectively rotatable
from the primary housing to alloW access to internal compo
nents covered thereby, both from the rear and top ofthe ?oor
cleaning machine.
The front housing ofone embodiment ofthe present inven
tion accommodates various controls associated With the ?oor
cleaning machine. These controls may indicate the amount of
cleaning and spent ?uid in the tanks, control poWer, battery
life, etc. The front housing also accommodates a steering
Wheel that alloWs the operatorto selectively control the move
ment of the ?oor cleaning machine. The steering Wheel is
interconnected to a steering mechanism by a shaft. Rotation
ofthe steering Wheel causes the connected shaft to similarly
rotate, ultimately causing a change to the angle of the steer
able Wheel.
The steering shaft ofone embodiment ofthe present inven
tion is able to move as the housing rotates Without requiring
disconnection from the steering mechanism or removal ofthe
steering Wheel. The shaft of one embodiment includes a sta
tionary rigid portion that is slidably interconnected to a ?ex
ible portion that selectively slides over the rigid portion and
?exes When the front housing is rotated aWay from the pri
mary housing. More speci?cally, in order to also accommo
date the movement of the shaft, a slip ?tting is preferably
interconnected to the ?exible portion to alloW the steering
shaft to separate from the chassis, by sliding over the rigid
portion, While remaining interconnected to the steering
mechanism.
The rear housing of one embodiment ofthe present inven
tion may accommodate a tank that stores at least one ofclean
Water or Waste Water. In one embodiment, the tank is capped
prior to rotating it aWay from the primary housing to avoid
spillage ofthe tank contents. One advantage ofsome embodi
ments of the present invention described herein, is that a

compact ?oor cleaning machine is provided that allows for
easy and selective access to internal components of the
machine Without having to remove the machine housing, a
timely and thus costly process.

electrical components of the machine. The front Wheel 14,
Which is steerable, and the rear Wheel 10 (a second rear Wheel
is not shoWn but positioned on the opposite side of the
machine) Which generally is not steerable, is associated With
the chassis. The cleaning apparatus 30, such as a cleaning
brush and a squeegee, is also associated With the chassis. One
skilled in the art Will appreciate that the cleaning apparatus
may be a brush, a scrubber, a bumisher, a squeegee, a spray
noZZle, spent ?uid pick-up mechanism etc., some of Which
are described in detail in the patent described in previously
incorporated US. Pat. No. 7,533,435.
Referring noW to FIG. 2, the ?oor cleaning machine 2 of
one embodiment ofthe present invention is shoWn in a second
con?guration. Here, the front housing 34 and rear housing 38
have been rotated aWay from the primary housing 42 to
expose internal components ofthe ?oor cleaning machine 2.
Here, the steering Wheel 26 and control panel 50 are moved
along With the front housing 34. The connections associated
With the control panel 50 and the steering Wheel 26, i.e. the
steering shaft 22, remain associated With the chassis 6, Which
Will be described in further detail With respect to FIGS. 3 and
4. The internal components, such as a vacuum motor 46 are
thus exposed to be maintained or repaired. The front housing
34 of the embodiment shoWn, is hingedly interconnected to
the primary housing 42 by Way of a front hinge 54. One

Referring noW to FIGS. 3 and 4, the nature ofthe steering
shaft 22 is shown, With the remainder of the components
shoWn in FIGS. 1 and 2 having been removed for clarity. The
steering shaft 22 may be comprised ofa rigid portion 66, that
is interconnected to the steering Wheel 26 and a slip ?tting 70,
With a ?exible portion 74 therebetWeen. Rotation ofthe steer
ing Wheel 26 Will thus rotate the rigid portion 66, Which Will
rotate the ?exible portion 74 andthe slip ?tting 70, WhichWill
ultimately rotate the front Wheel 14 to alloW steering of the
?oor cleaning machines.
Referring speci?cally to FIG. 4, the steering Wheel 26 is
shoWn in a secondposition ofuse, Where the front housing has
been rotated aWay from the primary housing (see FIG. 2).
Here, one can quickly appreciate that When rotated, the ?ex
ible portion 74 Will ?ex to alloW the steering Wheel to be
maintained With the front housing. In addition, the slip ?tting
70 Will move upWardly aWay from the chassis 6. The slip
?tting 70 is slidingly interconnected to a shaft 78 that is
interconnected to at least one mechanism, such as a gear or
belt, that rotates the steerable front Wheel 14. As those in the
art Will appreciate the shaft 8 could also be directly connected
to the steering Wheel assembly.
In one embodiment, the shaft 78 is hexagonal and cooper
ates With a hexagonal opening in the slip ?tting 70 to alloW
rotation ofthe steering Wheel 26 to be translated to the steer
able shaft 22 to alloW the rotation ofthe steerable front Wheel
14. One skilled in the art Will appreciate, hoWever, that any
con?guration that provides rotational locking betWeen the
slip ?tting 70 and the shaft 78 that Would alloW for rotation of
the shaft 78 upon rotation of the slip ?tting 70 is Within the
scope of the disclosure.
The ?exible portion 74 may be constructed of nylon
impregnated rubber or any other compliant or ?exible mate
rial. Alternatively, a Wire overWrapped ?exible belloWs mem
ber may be used instead of a composite rubber member.
Further, in order to facilitate rotational translation of the
steering Wheel 26 to the steering mechanism, the ?exible
portion 74 may be comprised of a rubber tube Wrapped by a
?exible metal coil. Additionally, one of skill in the art Will
appreciate that a belloWs system may be used Wherein the slip
?tting 70 is omitted and the belloWs Would be directly inter
connected to the steering mechanism 18 and thus Would alloW
for bending of the steering shaft 22 and selective elongation
thereof if needed. One skilled in the art Will appreciate the
various systems that may be used to achieve the goal of
providing at least one of ?exibility in the steering assembly
and/or elongation thereofto accommodate the moving ofthe
front housing.
In one embodiment of the present invention the ?exible
portion 74 is made of steel reinforced rubber and is about 22
inches long. In addition, the steering shaft 78 is 9 inches long
and has a hexagonal exterior con?guration that ?ts into a
hexagonal opening ofthe slip ?tting 70. One skilled in the art
Will also appreciate that the shaft 78 may be holloW such that
the slip ?tting 70 ?ts Within the shaft 78, for example.
While various embodiments of the present invention have
been described in detail, it is apparent that modi?cations and
alterations ofthose embodiments Will occurto those skilled in
the art. HoWever, it is to be expressly understood that such
modi?cations and alterations are Within the scope and spirit
