Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority pursuant to 35 U.S.C.
119(e) to co-pending U.S. Provisional Patent Application Ser. No.
60/828,200, filed Oct. 4, 2006, the entire disclosure of which is
incorporated herein by reference.
FIELD OF THE INVENTION
[0002] The present invention relates generally to a dust mop. More
specifically, the present invention is concerned with a riding dust
mop machine and also with a dust mop device including a concave
shape that can be attached to a riding device and/or used manually
with a handle.
BACKGROUND OF THE INVENTION
[0003] Mops for cleaning floors have been used for over a century.
The mop was first patented in 1893 and has undergone many
improvements and variations over the years. A dry mop, often called
a dust mop, is usually characterized by a large, flat head that can
be pushed by a handle over a floor surface picking up dust, hair,
lint and other particles. Dust mops usually consist of three basic
parts: the mop head including a frame, an attachment mechanism that
links that mop head to the handle and the handle. The large flat
head typically includes a cleaning element made of cloth or other
material that picks up dust, hair, lint and other particles easily.
The cleaning element is typically slid around or otherwise
supported by the frame so that such cleaning element may be easily
removed from the frame for cleaning/laundering and/or disposal.
[0004] Dust mops are trusted fixtures in most homes, businesses and
schools. Dry mopping is typically used on hard floor surfaces and
usually preformed once a day (or more) in businesses and especially
in schools, hospitals, airports and other institutions. Dry mopping
an entire school (including a large gymnasium) or a large office
building can be a very mundane and time consuming task. To increase
efficiency dust mop heads have become increasingly longer and
wider, but manually cleaning large areas such as a school
gymnasium, even with a larger mop, is still a considerable task,
and the larger the mop size the greater the amount of labor
required by the user to manipulate the mop. Therefore, it would be
beneficial to provide a device that increases mopping efficiency
while at the same time reducing the amount of manual labor required
to mop an area.
[0005] The basic shape of the dust mop head has not varied much
over the last 100 or more years, with the mop head generally being
rectangular in shape. The problem with a rectangular shaped mop
head is that soil and debris can be lost off the ends of the mop as
the mop is pushed forward along the floor. The loss of debris from
the ends of the mop increases the time it takes to mop a floor due
to the additional time necessary sweep up the lost debris and/or to
overlap cleaning paths. Therefore, it would be beneficial to
provide a dust mop that minimizes and/or eliminates the loss of
debris from the ends of the mop head.
SUMMARY OF THE INVENTION
[0006] A principal object of the present invention is to provide an
improved dust mop. Another object of the invention is to provide an
efficient dust mop device that reduces the amount of labor and time
it takes to dry mop an area. Still another object of the instant
invention is to provide a dust mop that minimizes and/or eliminates
the loss of debris from the ends of the mop head.
[0007] The objects of the instant invention are accomplished
through the use of an automatic riding device with a trailing mop
attachment. The objects of the instant invention are further
accomplished with a concave shaped dust mop head that is used
manually or in conjunction with an automatic riding (or
walk-behind) device.
[0008] In one embodiment of the instant invention, a concave shaped
mop head is used manually. The manual use generally includes a mop
handle, a concave mop frame, a mop head, and a mechanism for
attaching the mop handle to the mop frame. The mop handle may be a
standard mop handle threaded at one end and constructed of
appropriate material such as wood, metal or plastic. The concave
mop frame has a crescent shape. When used manually the open ends of
the crescent are pushed away from the user. The concave mop frame
may be constructed from metal or other appropriate material. The
cleaning element of the mop head is made of fibrous material in the
same manner and using similar material as any typical rectangular
mop head now known or hereinafter discovered. The concave mop frame
may accommodate common rectangular cleaning elements that wrap
around the frame to conform to the shape of the frame or concave
cleaning elements specially designed to conform to the concave mop
frame.
[0009] The concave design of the mop head keeps heavier soil and
debris from being lost off the ends of the mop because soil tends
to move toward the middle of the concave mop head. This increases
efficiency when cleaning. This mop can be used on all hard floor
surfaces.
[0010] In another embodiment a mop frame is attached behind an
automatic riding device. In a preferred embodiment, the mop frame
is a concave mop frame such as the concave frame discussed above.
The concave mop frame is attached behind the automatic riding
device so that it tracks or follows the device. In one embodiment,
the concave dust mop is attached to the automatic riding device via
a frame plate that is mounted to the rear of the automatic riding
device and a bracket that is attached to the frame plate to support
the mop frame. A swivel cam harness is mounted within the bracket
with mop frame support arms attached to the swivel cam harness at
one end and to the mop frame at the other end. The frame plate, the
bracket mount, and the swivel cam harness together with the support
arms and the concave mop frame make up the mop assembly that can be
attached to any automatic riding device.
[0011] The mop assembly allows for the concave mop head to track
behind the automatic riding device without having to manually
reposition the concave mop head. The swivel cam hardness allows the
mop frame to rotate left and right (or back and forward) as the
swivel cam harness rotates within the bracket mount. The support
arms are also pivotally connected to the swivel cam harness so that
the mop frame can rotate up and down. This allows for the unique
ability of the mop of the instant invention to both track the
movement (left and right, etc.) of the riding device and to follow
the contours of the floor without missing low spots or riding over
high spots and losing the soil that is contained in the mop head.
In addition, the up and down rotation allows the mop frame to be
placed in an upright position during transport between cleaning
locations. The mop frame is releasably connected to the support
arms to provide a break-away feature that allows the mop frame to
break free from the automatic riding device in the event the mop
head encounters an obstruction (such as a pole, chair, etc.) that
might damage the assembly. This safety feature protects the mop
assembly and the automatic riding device from unnecessary damage.
The ends of the support arms include horizontal slots in which
bolts (or other support members) pass through vertically and
connect to the mop frame. Wing nuts (handles or other attachment
members) are tightened down on the bolts to frictionally hold the
mop frame to the support arm. When the mop encounters an
obstruction, the bolt will slide out of the slot to release the mop
frame from the support arm.
[0012] The concave mop frame is raised and supported in an upright
position when not in use or when traveling across soft floors. The
mop frame is maintained in the upright position by pins or bolts
that extend through holes in the support arms. When the mop frame
is rotated upward the support arms rotate up and around (or
between) a pair of arms extending from the swivel cam harness. The
arms of the swivel cam harness include holes that correspond to the
holes in the support arms when the frame is in its upright
position, allowing the pins or bolts to extend through the holes in
the support arms and in the arms of the swivel cam harness to
retain the frame in the upright position.
[0013] The automatic riding device is more convenient than
traditional manual walk-behind or push mops and provides for
improved ergonomics and better performance. An automatic riding
device saves time because it is faster than pushing a mop around. A
user can ride on top the automatic riding device similar to riding
a scooter or riding lawn mower. Not only does it save the user time
and the employer money, it alleviates strain on the users back and
allows for a wider variety of users. It will be appreciated that
the mop frame of the instant invention can be sold in combination
with and/or permanently attached to the riding device, or
alternatively can be separate attachment that can be mounted or
attached to any of a variety of riding devices, such as a
4-wheeler, scooter, golf cart, wheel chair or any other type of
motorized vehicle without departing from the spirit and scope of
the instant invention. In addition, it will be appreciated that
other mechanisms to attach the mop frame to a riding device, such
as a ball and hitch, or other harnesses, may be utilized without
departing from the spirit and scope of the instant invention.
[0014] In one embodiment of the instant invention, the concave mop
frame is capable of use both as a manual mop and also with a riding
device. In such an embodiment the mop frame may include bolt
attachments to connect to the support arms, as well as a centrally
located threaded mount to connect to a mop handle. This allows the
user to convert from one use to another depending upon the desired
use. When it is not convenient to use the automatic riding device,
such as in a tight space (i.e. in a closet), the user can detach
the concave mop frame from the automatic riding device and engage a
mop handle.
[0015] In another embodiment of the invention, an automatic device
is used that does not have a riding capability. For example, an
automatic device such as a hand powered push-mop or self-propelled
device where the concave mop head is in front of the user and the
opening of the crescent is away from the user, may be utilized.
Such automatic devices increase the efficiency of the user because
it takes less time and effort to mop the same area as would be
required by a manual mop.
[0016] The foregoing and other objects are intended to be
illustrative of the invention and are not meant in a limiting
sense. Many possible embodiments of the invention may be made and
will be readily evident upon a study of the following specification
and accompanying drawings comprising a part thereof. Various
features and subcombinations of invention may be employed without
reference to other features and subcombinations. Other objects and

[0026] As required, a detailed embodiment of the present inventions
is disclosed herein; however, it is to be understood that the
disclosed embodiment is merely exemplary of the principles of the
invention, which may be embodied in various forms. Therefore,
specific structural and functional details disclosed herein are not
to be interpreted as limiting, but merely as a basis for the claims
and as a representative basis for teaching one skilled in the art
to variously employ the present invention in virtually any
appropriately detailed structure.
[0027] Referring to FIGS. 1 through 5, a riding mopping machine 10
of a preferred embodiment of the instant invention is shown and
described. Mopping machine 10 includes automatic riding device 20
and trailing mop attachment 30. In the depicted embodiment,
automatic riding device 20 is a scooter, such as a three wheeled or
four wheeled electric scooter typically used for providing mobility
to elderly persons or other persons with physical disabilities or
injuries. Nevertheless, it will be appreciated that alternative
riding devices may be utilized without departing from the spirit
and scope of the instant invention. Trailing mop attachment 30 is
generally concave or crescent shaped to prevent dirt and debris
from being lost off the ends of mop attachment 30.
[0028] Mop attachment 30 is attached to the rear of automatic
riding device 20 so that it tracks or follows riding device 20. The
concave shape of mop attachment 30 tends to cause dirt and debris
to move toward the middle of the concave mop, preventing such
debris from being lost off the ends of the mop attachment. Mop
attachment 30 is attached to the rear of automatic riding device
via frame plate 40 that is mounted to the rear of the automatic
riding device via bolts 42. Bracket 50 is attached to frame plate
40 via bolts 52. Swivel cam harness 60 is mounted within bracket 50
with mop frame support arms 70 each attached to swivel cam harness
60 at one end and to mop attachment 30 at the other end. Frame
plate 40, bracket mount 50, and swivel cam harness 60 together with
support arms 70 and the concave mop attachment 30 make up a mop
assembly that can be attached to virtually any automatic riding
device. Nevertheless, it will be appreciated that various
modifications to the components of the mop assembly may be
desirable, or even necessary, depending upon the particular
structure of the riding device to which the mop assembly is
attached. Such modifications will be apparent to those of ordinary
skill in the art. For example, the shape or configuration of frame
plate 40 may be altered to attach to riding devices of various
configurations. Furthermore, it will be appreciated that various
components of the mop assembly may be utilized independently of
other components, without departing from the spirit and scope of
the instant invention. For example, bracket mount 50 may be
attached directly to the rear of a riding device without the us of
frame plate 40.
[0029] Referring to FIGS. 3a through 3c, frame plate 40, bracket
mount 50 and swivel cam harness 60 are described in further detail.
Frame plate 40 includes central plate member 44 and side plate
members 46 that protrude generally orthogonally from each end of
central plate member 44 to connect to the frame of riding device 20
using bolts 42 (not shown in FIGS. 3a-3c). In the embodiment shown,
central plate member 44 and side plate members 46 are constructed
of 3/16 inch steel plates that are welded together. Nevertheless,
it will be appreciated that alternative materials may be utilized
without departing from the spirit and scope of the instant
invention. Furthermore, it will be appreciated that alternative
means of mounting frame plate 40 to the riding device (including,
but not limited to welding) may be utilized without departing from
the spirit and scope of the instant invention.
[0030] Bracket mount 50 includes central bracket member 54 and
upper and lower bracket members 56 and 58 (respectively). Central
bracket member 54 of bracket mount 50 is connected to central plate
member 44 using bolts 52. In the embodiment shown, central bracket
member 54 and upper and lower bracket members 56 and 58 are
constructed of 3/16 inch steel plates that are welded together.
Nevertheless, it will be appreciated that alternative materials may
be utilized without departing from the spirit and scope of the
instant invention. Furthermore, it will be appreciated that
alternative means of mounting bracket mount 50 to frame plate 40
(including, but not limited to welding) may be utilized without
departing from the spirit and scope of the instant invention. As
shown in FIG. 3b, the edges of upper and lower bracket members 56
and 58 are rounded to reduce the potential for user injury.
[0031] Swivel cam 60 includes cam body member 64 and retention
plate members 66 extending generally orthogonally from the top of
cam body member 64. In the embodiment shown, cam body member 64 is
constructed of 1/8 inch steel square tubing that is capped with a
steel plate at the top and bottom of cam body member 64 to provide
a generally solid or continuous outer surface for cam body member
64. Retention plate members 66 are constructed of 1/8 steel plates
that are welded to the top portion of opposing sides of cam body
member 64. Hole 61 is drilled or otherwise formed through the top
and bottom cap plates of swivel cam body member 64 to allow bolt 62
to pass longitudinally through cam body member 64 to mount swivel
cam 60 between upper and lower bracket members 56 and 58 of bracket
mount 50. A reinforcement sleeve may also be utilized through hole
61 to reduce wear. Hole 67 is drilled or otherwise formed through
the side of the lower portion (below retention plate members 66 and
68) of cam body member 64 to allow bolt 72 to pass through cam body
member 64 generally orthogonally to bolt 62 to mount support arms
70 to opposing sides of cam 60. Spacers or washers are included
between support arms 70 and the outer surface of cam body member 64
so that support arms 70 are spaced outside of and generally
parallel to retention plate members 66, allowing support arms 70 to
be rotated up and around the outside of retention plate members 66.
Holes 65 are drilled or otherwise formed through the outer ends of
retention plate members 66 to allow a bolt or retention pin to be
inserted through holes 65 to retain support arms in an elevated
position when support arms are rotated upward. Support arms 70 may
be rotated upward beyond holes 65 and the pin may then be inserted
to prevent support arms 70 from rotating back down. Alternatively,
holes 75 may be formed through support arms 70 (as shown in FIG. 2)
to coincide with holes 65 when support arms 70 are rotated upward,
such that the pin would be inserted through holes 65 and 75 to
retain support arms 70 in an elevated position. It will be
appreciated that alternative materials and mounting means to those
described in this paragraph may be utilized without departing from
the spirit and scope of the instant invention. As shown in FIG. 3a,
the edges of retention plate members 66 are rounded to reduce the
potential for user injury.
[0032] As is shown in FIGS. 1 and 2, support arms 70 extend from
swivel cam 60 in a direction generally parallel to and beyond
retention plate members 66 of swivel cam 60 to allow support arms
to be rotated about retention plate members 66. Beyond the ends of
retention plate members 66 (to allow clearance for proper rotation)
support arms are bent outward to provide a wide base for supporting
mop attachment 30, which itself is generally wider than the width
of riding device 20. Connecting member 76 extends between and is
connected to support arms 70 via bolts 74. Connecting member 76
provides rigidity to support arms 70 and causes support arms 70 to
rotate upward and downward in unison with each other. The outermost
ends of connecting members 70 (opposite the ends connect to swivel
cam 60) are bent generally downward for attachment to break-away
support members 80, which releasably connect support arms 70 to mop
attachment 30. In the depicted embodiment, connecting arms 70 are
constructed of steel; however it will be appreciated that
alternative materials and mounting means to those described in this
paragraph may be utilized without departing from the spirit and
scope of the instant invention.
[0033] As is shown in FIGS. 4a and 4b, break-away support members
80 each include foot member 84 and arm-retention members 86.
Support arm is mounted between arm-retention members 86 using bolt
82. Foot member 84 includes horizontal slot 87 through which
threaded member 36 of mop attachment 30 extends. Wing nut 85 is
threaded onto threaded member 36 to frictionally maintain a
connection between foot member 84 and frame members 34 of mop
attachment 30. In the event mop attachment 30 encounters an
obstruction during operation, threaded member 36 will slide out of
slot 87. In the depicted embodiment, break-away support members 80
are constructed of steel; however it will be appreciated that
alternative materials and mounting means to those described in this
paragraph may be utilized without departing from the spirit and
scope of the instant invention.
[0034] Referring to FIG. 5, a preferred framework of mop attachment
30 is shown. Mop attachment 30 is constructed of a metal framework,
in a manner and of similar materials to mop frames of the prior
art. In the depicted embodiment, the framework is constructed of
metal; however it will be appreciated that alternative materials
may be utilized without departing from the spirit and scope of the
instant invention. The framework of mop attachment 30 includes an
outer perimeter frame 32, and cross-members 34. Threaded members 36
are mounted between pairs of cross-members 34 and extend generally
orthogonally from the framework of mop attachment 30 for connecting
to support arms 70 in the manner described above. The framework of
mop attachment 30 further includes central frame 38 and
cross-member 39 within central frame 38 for connecting to a mop
handle of the type that is traditionally used with mop frames of
the prior art. This allows mop attachment 30 to be utilized both in
connection with riding device 20 as well as manually. As is shown
in FIG. 1, cleaning element 31 is mounted to the framework of mop
attachment 30. Cleaning element 31 is made of fibrous material in
the same manner and using similar material as any typical
rectangular mop head now known or hereinafter discovered. The
concave mop frame may accommodate common rectangular cleaning
elements that wrap around the frame to conform to the shape of the
frame or concave cleaning elements specially designed to conform to
the concave mop frame. As is shown in FIG. 1, cleaning element 31
includes slit 37 that extends along the length of roughly half of
cleaning element 31 to allow cleaning element to be placed around
and removed from mop attachment 30. Closures, 33, such as hook and
pile or snap fasteners, are utilized to close slit 37 around the
framework of mop attachment 30. Cutouts are also located in
cleaning element 31 to allow access to the framework at the
locations at which the support arms are connected to the
framework.
