Swing-wing dust mop
Abstract
A dust mop includes a dust-gathering fabric portion which is
secured to a beaded mounting vane that, in turn is slid through a
plurality of slots formed on a pair of pivoted arm members. The arm
members are positively connected to one another by gear segments
which mesh together so that the arm members may be rotated to
either increase or decrease the area engaged by the fabric portion.
A bracket member which has bearings therein for pivotally mounting
the arm members is used to attach the arm members to a handle
socket. This bracket member is molded from a single piece of
plastic material which folds over along a thin hinge portion
thereof to form a housing having top and bottom panels. The panels
are fastened together by detents which project from the top panel
into apertures formed in the bearings which project from the bottom
panel.

Description
BACKGROUND OF THE INVENTION
This invention relates to improvements in cleaning implements. More
particularly, this invention relates to improvements in mops and
the like.
When mopping a floor, it is often desirable and necessary to
increase the area of floor engaged by the mop to reduce the amount
of time needed to complete a task. The problem of increasing the
area of a floor engaged by a cleaning surface, such as the fabric
head of a dust mop, has of course been recognized and has been
dealt with by those involved in cleaning large floor areas, such as
those of industrial plants or the like. The prior art includes
several patents which disclose mops and brooms having pivoted
sections which fold away from one another to increase the area of
floor engaged by the mop or broom. U.S. Pat. Nos. 2,756,453,
1,784,567, 2,614,281 and 2,860,360 exemplify this type of device.
However, as seen in the aforementioned disclosures, this type of
cleaning device is generally rather heavy-duty, large and
expensive, and generally not suitable for home use.
In addition to being able to increase the area of floor engaged by
a cleaning implement such as a mop, it is also desirable in
utilizing the same cleaning implement to be able to decrease the
floor area engaged in order to get under and around furniture. This
again has not been adequately dealt with by prior art devices. In
the past, the ordinary house mop had to be turned sideways in order
to accomplish this. When the mop is turned sideways, the handle,
which is generally pivoted thereto, cannot pivot down so that the
mop can be easily pushed under a low-lying object, such as a shelf
or the supporting structure of a chair or the like. This deficiency
in the ordinary house mop causes considerable inconvenience and
irritation.
Furthermore, the above-cited devices do not utilize the technology
which is currently being applied in the home consumer market. For
example, the afore-mentioned devices do not utilize resilient,
light plastic supporting structures which can be readily assembled.
Consequently, the afore-described devices cannot be broken down
into easily assembled component parts for storage and shipment. It
is well known that great economy results from being able to store
and ship unassembled articles, and the cleaning implements of the
prior art do not teach how to apply this economy to dust mops
purchased by consumers for home use.
SUMMARY OF THE INVENTION
In view of the afore-described problems, it is an object of the
instant invention to provide a new and improved cleaning
implement.
It is another object of the instant invention to provide a new and
improved cleaning implement which is foldable so as to either
reduce or increase the area engaged by the cleaning implement.
It is still another object of the instant invention to provide a
cleaning implement which can be made from lightweight plastic
materials.
It is a further object of the instant invention to provide a
cleaning implement, such as a mop, which can be broken down into
easily assembled component parts for storage and shipment.
In accordance with these and other objects, the instant invention
includes a mop head, which may be disposable, having an elongated
array of fabric-type material which is attached to a mounting vane
that is, in turn, mechanically secured to a pair of pivotable arms.
The arms are mounted in a bracket member and are positively coupled
so as to move in opposite directions when only one of the arms is
pivoted. The bracket member has a socket pivoted thereto which
receives a handle.
Other objects and advantages of the present invention will become
apparent from the following description of a preferred embodiment
of the invention, taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF THE DRAWINGS
Referring now to FIG. 1, there is shown a mop, according to the
invention, which includes a mop head 20 having an array of fabric
strands 21--21 which are used to collect dust. It is to be
understood that the array of fabric strands 21 may also be any type
of dirt-removing or dirt-transporting fabric or device. The mop
head 20 is secured to a pair of arms 22 and 23 which project from a
connecting bracket, designated generally by the numeral 24. The
connecting bracket 24 has a pair of flanges 26 and 27 extending
upwardly from a top panel 25 to which a socket, designated
generally by the numeral 28, is pivoted. The socket 28 threadably
receives a wooden or plastic handle 29.
Referring now to FIG. 2, it is seen that the fabric strands 21 are
secured to a binding strip or vane 31 by stitching (not shown) or
some other conventional securing method. The vane 31 is preferably
of a flexible material, such as vinyl or the like, and has a
circular bead 32 extending along the top edge thereof. The circular
bead 32 has a diameter greater than the width of the vane portion
31 to which the strands are attached, and is received in a slot 33
which projects from a bottom panel 34 of the connecting bracket 24.
The slot 33 is defined by a pair of converging ribs 35--35 which
have a space therebetween which is large enough for the vane 31 to
pass therethrough, but which is narrower than the bead 32. An
enlarged view of the slot 33 is seen in FIG. 16.
As best seen in FIGS. 2 and 3, the socket 28 has a forked end 36
which is inserted between the flanges 26 and 27, and is pivoted on
a pair of projections 37 and 38 which extend from the flanges into
apertures 39 and 41 formed in the forked end of the socket. FIG. 2
shows the socket 28 and handle 29 projecting from the bracket 24 in
what might be called a normal cleaning attitude. However, it is to
be understood that the socket 28 can pivot about the projections 37
and 38, either clockwise or counter-clockwise from the position
shown in FIG. 2 to lay either along the bracket 24 or away from the
bracket 24. When the socket 28 is thus pivoted, the mop head 20 and
the handle 29 will extend in generally the same plane so that the
mop may be stored easily in a closet or the like. In addition, when
the handle 29 is pivoted down in the clockwise direction, the mop
may be easily slid under low-lying furniture.
In order to retain the socket 28 and the handle 29 in either of the
afore-mentioned positions, and in order to prevent the mop head
from assuming an inconvenient angle relative to the handle 29 while
a floor is being mopped, a rib 43 projects up from the top panel 25
of the bracket 24 to engage a pair of detents 44 and 45 projecting
from the forked end 36 of the socket 28. As the detents 44 and 45
ride over the rib 43, they cam the two prongs of the forked end 36
together so as to decrease the distance separating the ends of the
detents. This allows the detents 44 and 45 to slide over the rib 43
and provides a way of holding the handle 29 in either an overlying
or extended position relative to the mop head 20 so that greater
flexibility for using the mop results, for example, for use under
low-lying objects and around furniture legs.
As best seen in FIG. 3, the arm members 22 and 23 are pivoted about
bearings 51 and 52 which project from the bottom panel 34 of the
bracket 24. The arms 22 and 23 may assume either the extended
configuration indicated by the dotted lines in FIG. 3, or the
narrow configuration shown by solid lines in FIG. 3. In order to
coordinate the pivotal motion of the arm members 22 and 23 so that
as one of the arms pivots, the other arm will pivot in the opposite
direction, each of the arms has an integral gear segment 53 which
meshes with a gear segment on the other arm to positively couple
the arms together. It is to be understood that such coordinated
motion of arm members 22 and 23 could also be accomplished by
rotating an indicator dial (not shown in the figures) which,
alternatively, meshes with the gear segment of only one of the
meshed arm members, or meshes with intermediate members having gear
segments that in turn mesh with the gear segments of the arm
members.
It has been found that it is desirable for the arm members 22 and
23 to have a mid-position between the extended dotted line
configuration and the narrow solid line configuration. This is
accomplished by detents 56--56 which project from each of the arm
members 22 and 23 to engage apertures 57 formed in the bottom panel
34 of the bracket member 24 (see FIG. 11). As the arm members 22
and 23 rotate between the dotted line and solid line positions, the
projections 56 are received in the apertures 57 to retain the arm
members and thus the mop head 20 in the desired configuration.
In order to distribute the fabric strands 21 so that the mop can
easily clean along walls and the like without having to turn the
mop sideways, each of the arms 22 and 23 have angular bends 59 and
60 therein which extend rearwardly from the arms.
An important consideration in the instant invention is that the
instant invention provides a cleaning implement which can be
readily assembled. This is due, in part, to the construction of the
bracket 24. As best seen in FIG. 11, the bracket 24 is formed of a
single piece of material which is hinged along a thin seam 58 which
joins the bottom panel 34 of the bracket to the top panel 25. When
the bracket 24 is folded about the hinge 58, the top panel 25
overlies the bottom panel 34 aligning a pair of detent members,
designated generally by the numeral 61--61, with apertures 62--62
that project through the bearings 51 and 52. Upon pressing the top
panel 25 and bottom panel 34 together, the detents 61--61 slide
into the apertures 62--62.
As best seen in FIGS. 2 and 17, the detents 61--61 are bifurcated
and have shoulders 63--63 thereon which fit beneath annular
shoulders 64--64 projecting into the apertures 62--62 of the
bearings 51 and 52. This securely fastens the top panel 25 to the
bottom panel 34, forming the bracket 24 into a housing for
supporting the arms 22 and 23.
Generally, the mop is put together by placing the arms 22 and 23
over their respective bearings 51 and 52 with the gear sectors 53
and 54 in meshed engagement and the detents 56--56 engaging the
same relative positioning slots 57--57. The top panel 25 of the
bracket 24 is then folded at the hinge 58 until the detents 61--61
are aligned with the apertures 62--62 on bottom panel 34. The
panels 25 and 34 are then squeezed together to snap the shoulders
63--63 beneath the annular shoulders 64--64 to hold the panels
together and the arms 22 and 23 in place. Preferably, the resulting
unit is then ultrasonically vibrated to promote the melting of
projections 75 (see FIG. 11) and the formation of a weld at these
locations between panels 25 and 34, which ensures the secure
engagement of meshed arms 22 and 23.
The threaded handle socket 28 is then mounted between the flanges
26 and 27 by squeezing the forked end 36 of the threaded socket
together so that the socket will slide between the pivots 37 and
38. In order to facilitate sliding the socket into place, the
pivots 37 and 38 become aligned with the apertures 39 and 41 in the
forked end 36 of the threaded socket 28, the prongs of the forked
end will spring outwardly to retain the threaded socket pivotally
between the flanges 26 and 27.
The mop head 29 is attached to the arms 22 and 23 by sliding the
bead 32 of the vane 31 into slots 68 and 69 extending between
converging ribs 71--71 and 72--72 projecting from each of the arm
members. The vane 31 is slid through the slots 71--71 and 72--72
until short portions thereof project from the end of each of the
arms 22 and 23. These short portions are then doubled back and
pressed into slots 73--73 formed by deflectable ribs 74--74, which
converge toward the inner ribs 72--72. The ends of the vane 31 are
consequently secured to the arms 22 and 23 so that the vane and the
associated mop head 20 cannot be slid out of engagement with the
arm members.
It is preferable that the arm members 22 and 23, the bracket 24 and
the threaded socket 28 all be made of a resilient,
self-lubricating, plastic material to facilitate easy assembly and
operation of the afore-described cleaning implement.
While a preferred embodiment of the invention has been described
herein it is to be understood that such description is only
exemplary with many different embodiments of this invention being
possible without departing from the spirit or scope thereof as
defined in the appended claims.
For example, it is contemplated that the cleaning implement
described, with suitable modifications by anyone skilled in the
art, has other applications such as waxing, polishing, as well as
application of surface treating substances such as insect
repellents, dust repellants, etc.
