DETAILED DESCRIPTION
[0037] Referring to the drawings and in particular to FIGS. 1-2,
exemplary embodiments of handles according to the present
disclosure are shown and are generally referred to by reference
numeral 10. Advantageously, handles 10 have both a stationary
portion 12 and a rotational portion 14, which have been found by
the present disclosure to provide enhanced utility by allowing the
user more gripping and use choices than previously possible.
[0038] Handles 10 are shown in use with a pole 16 having a tool 18.
For ease of discussion, tool 18 is shown as cleaning implement as
disclosed in Applicant's own U.S. application Ser. No. 15/238,262,
which is incorporated herein by reference. Of course, it should be
recognized that handles 10 are contemplated for use with any
desired tool. Similarly, pole 16 is shown for ease of discussion as
being either a bent/offset pole (FIG. 1) or a straight pole (FIG.
2). Of course, it should also be recognized that handles 10 are
contemplated for use with any desired pole, including fixed length
poles or telescoping poles. In this illustrative embodiment, the
tool 18 includes a flat mop 100 configured to receive a cleaning
cloth 102. The flat mop 100 attaches to the pole 16 by a universal
joint 104 having a first pivot axis 106 and a second pivot axis
108. A rear facing agent dispensing device 110 is arranged to
dispense a cleaning agent from a reservoir 112. Advantageously, the
tool 18 is easily configurable to dispense the cleaning agent under
the force of gravity from the reservoir 112. The universal joint
104 is, preferably, rotatable about the two axes 106, 108 to
improve the ease of use of tool 18. In some embodiments, joint 22
is configured so that at least one of the two axes 106, 108 is
lockable to improve the ease of use of tool 18. Of course, it is
contemplated by the present disclosure for the universal joint 104
to have unrestrained movement and, thus, to lack any lock. The
agent dispensing device 110 is illustrated as part of an agent
dispensing system to dispense the cleaning agent from the reservoir
112 proximate a leading edge of the flat mop 100 in a pull
direction.
[0039] Handles 10 are shown in FIG. 1 and FIG. 2 with two different
variants, namely as a top handle 20, shown in more detail in FIG. 3
and a middle handle 22, shown in more detail in FIG. 4. Top handle
20 and middle handle 22 each include stationary portion 12 and
rotational portion 14.
[0040] Additionally, top handle 20 includes an activation trigger
24 that can be operatively connected to one or more portions of
tool 18. In the illustrated embodiment, trigger 24 is positioned on
the rotational portion 14. Of course, it is contemplated by the
present disclosure for trigger 24 to be positioned on the
stationary portion 12. Alternately in another embodiment, and as
shown in FIG. 5, it is contemplated by the present disclosure for
top handle 20 to lack any trigger. Moreover and although not shown,
in still further embodiments it is contemplated by the present
disclosure for middle handle 22 to include a trigger positioned on
either stationary or rotational portions 12, 14.
[0041] In some embodiments, handles 20, 22 can include one or more
gripping regions 26. Gripping regions 26 can be formed of material
that provides increased friction, provides softer materials than
pole 16, provides raised or textured areas, provides a diameter
large enough for comfortable gripping as pole 16 can of the be too
small to easily hold, or any other attribute to assist in gripping.
For example, it is contemplated by the present disclosure for
handles 10 to be made of any desired material. For example, handles
20, 22 can be made of plastics such as, but not limited to,
polypropylene (PP), polyoxymethylene (POM), acrylonitrile butadiene
styrene (ABS), and others, and can include one or more
thermoplastic elastomers (TPE) gripping regions 26.
[0042] Top handle 20 is described in more detail with reference to
FIG. 6 and FIG. 7. Top handle 20 includes stationary portion 12,
rotational portion 14, and a rotational coupler 30. Rotational
coupler 30 secures stationary and rotational portions 12, 14 to one
another so as to allow the portions to freely rotate with respect
to one another about a longitudinal axis (A), but prevents
translational movement of the portions with respect to one another
along the axis (A). Stationary portion 12 is secured to pole 16 in
a manner that prevents rotation about the axis (A) and prevents
translational movement along the axis (A).
[0043] As used herein, the terms "freely rotate" and "free
rotation" shall mean rotate at a torque of less than about 15
kg-mm, with less than 10 kg-mm being desired, and less than 3 kg-mm
being desired.
[0044] In one or more of the embodiments disclosed herein, portions
12, 14 have a length (L1, L2) along the axis (A) that is sufficient
to allow the user to grip the respective portion. In some
embodiments, stationary portion 12 has a length (L1) of between 2
to 4 inches, while rotational portion 14 has a length (L2) of
between 4 to 6 inches with between 4 to 5 inches being desired.
[0045] Here, the present application has found that--particularly
in middle handle 22--that the length (L1) of stationary portion 12
need not be sufficient to receive the entire hand of the user.
Rather, it has been determined that length (L2) of stationary
portion 12 of middle handle 22 having enough length to receive one
or two fingers (i.e., about 2 inches) provides sufficient area for
the user to control tool 18 by preventing rotation when desired.
For example, positioning of stationary and rotational portions 12,
14 into a unitary assembly immediately adjacent one another allows
the user to have their hand bridge the two portions so that some
fingers are on the stationary portion 12 and others are on the
rotational portion 14. In this manner, the user can switch between
grasping the stationary portion 12 and grasping the rotational
portion 14 by merely adjusting which of their fingers is applying
pressure to the handles 20, 22. In some embodiments, portions 12,
14 are configured with outer diameters that are common to allow
easy transition between the two portions and/or to allow for
grasping of both portions with different fingers of the same
hand.
[0046] During assembly, rotational coupler 30 is inserted into a
bore 32 of stationary portion 12. Coupler 30 is fixedly secured to
rotational portion 14 so as to secure portions 12, 14 to one
another in allow free rotation about axis (A), but prevent
translational movement of the portions along axis (A). For example,
coupler 30 can have screws 34 passed through the coupler and into
nuts 36 held by rotational portion 14.
[0047] Of course, it is contemplated by the present disclosure for
portions 12, 14 to be secured to one another in any desired manner
that is sufficient to allow free rotation of the portions with
respect to one another about the axis (A), but to prevent
translational movement of the portions with respect to one another
along the axis (A).
[0048] Finally, stationary portion 12 is secured to pole 16. In the
illustrated embodiment, stationary portion 12 includes a stationary
coupler 38 that receives a rivet or other mechanical fastener (not
shown) to secure the stationary portion to pole 16 in a manner that
prevents rotation about the axis (A) and prevents translational
movement along the axis (A). Of course, it is contemplated by the
present disclosure for stationary portion 12 to be secured to pole
16 in any desired manner that is sufficient to prevent rotation
about the axis (A) and prevent translational movement along the
axis (A) such as, but not limited to, a press fit, an adhesive
connection, a welded connection, and any others.
[0049] Middle handle 22 is described in more detail with reference
to FIG. 8. Middle handle 22 includes stationary portion 12,
rotational portion 14, and a fixing coupler 40. Coupler 40 captures
rotational portion 14 between the coupler and stationary portion 12
so as to allow the portions 12, 14 to freely rotate with respect to
one another about axis (A), but to prevent translational movement
of the portions 12, 14 along the axis (A).
[0050] Additionally, stationary portion 12 is secured to pole 16 in
a manner that prevents rotation of the stationary portion about the
axis (A) and prevents translational movement of the stationary
portion along the axis (A). In the illustrated embodiment,
stationary portion 12 includes a stationary coupler 38 that
receives a rivet or other mechanical fastener (not shown) to secure
stationary portion 12 to pole 16. Of course, it is contemplated by
the present disclosure for stationary portion 12 to be secured to
pole 16 in any desired manner that is sufficient to prevent
rotation about the axis (A) and prevent translational movement
along the axis (A) such as, but not limited to, a press fit, an
adhesive connection, a welded connection, and any others.
[0051] Similarly, coupler 40 receives a rivet or other mechanical
fastener (not shown) to secure the coupler 40 to pole 16 in a
manner that prevents rotation about the axis (A) and prevents
translational movement along the axis (A). Of course, it is
contemplated by the present disclosure for coupler 40 to be secured
to pole 16 in any desired manner that is sufficient to prevent
rotation about the axis (A) and prevent translational movement
along the axis (A) such as, but not limited to, a press fit, an
adhesive connection, a welded connection, and any others. In this
manner, rotational portion 14 is freely rotatably between coupler
40 and stationary portion 12 in a desired position on pole 16.
[0052] During assembly, stationary portion 12 includes a region 42
that is inserted into a bore 44 of rotational portion 14. Coupler
40 and stationary portion 12 are fixedly secured to pole 16 so as
to secure rotational portion 14 between the coupler and the
stationary portion.
[0053] Advantageously, stationary portion 12 remains in the preset
position on pole 16 without rotation about axis (A) or translation
along axis (A), while rotational portion 14 remains in the preset
position on pole 16 without translational movement along axis (A),
but in a manner that allows free rotation about axis (A). Moreover,
portions 12, 14 have lengths (L1, L2) that allow either portion to
be grasped by the user. It has been determined by the present
disclosure that handles 20, 22 allow the user to grip tool 18 in a
plurality of combinations not previously possible.
[0054] Handles 10 of the present disclosure find use with pole 16
configured as the bent/offset pole and tool 18 that requires a
back-and-forth cleaning path such as in FIG. 1. The back-and-forth
cleaning path is shown in FIG. 9, where tool 18 is pulled along a
surface being cleaned while the leading edge (Le) of the tool 18 is
moved back-and-forth. The back-and-forth motion can be efficient
for cleaning large areas. The ease of movement of tool 18, or lack
thereof, can be magnified in instances where the total surface area
of the surface being cleaned/conditioned is large--either by virtue
of there being a single large surface or multiple smaller surfaces.
Handles 10 of the present disclosure have been found to reduce
fatigue by improving the efficiency of motion by increasing the use
of larger muscle groups when cleaning is desired when
cleaning/conditioning surfaces by providing more flexibility to
meet each user's particular method of inducing the back-and-forth
cleaning path.
[0055] Specifically, it has surprisingly been found by the present
disclosure that different users induce the same back-and-forth
cleaning path with such bent/offset poles 16 in very different
manners--such that providing handles 20, 22 both with stationary
and rotational portions 12, 14 has been found to particularly
suited to maximize the gripping options for the users. For example,
some users exclusively make use of rotational portion 14 of both
handles 20, 22 to induce the back-and-forth cleaning path. Other
users primarily make use of stationary portion 12 of middle handle
22 to induce the back-and-forth cleaning path while gripping
rotational portion 14 of upper handle 20 so that the upper handle
rotates freely. Still other users primarily make use of stationary
portion 12 of top handle 20 to induce the back-and-forth cleaning
path while gripping rotational portion 14 of middle handle 22 so
that the middle handle rotates freely. Still other users make
primary use of stationary portions 12 of both top and middle
handles 20, 22.
[0056] Advantageously, handles 20, 22 allow the end user to
determine which combination of stationary/rotational portions 12,
14 to use for each of the handles works best for them to create the
desired back-and-forth motion. Further, handles 20, 22 allow the
end user to easily adjust the stationary/rotational grip for each
of the handles without having to significantly change hand
position, which improved ergonomics and reduced fatigue.
[0057] Handles 20, 22 are further configured, due to the
integration of both stationary and rotational portions 12, 14 into
a unitary assembly immediately adjacent one another, so that the
user can allow their hand to bridge stationary and rotational
portions 12, 14 so that some fingers are on the stationary portion
and others are on the rotational portion. In this manner, the user
can switch between grasping the stationary portion 12 and the
rotational portion 14 by merely adjusting which of their fingers is
applying pressure to the handles 20, 22.
[0058] Moreover, it has been found by the present disclosure that
use of only handles that freely rotate creates issues when
utilizing tool 18 in cleaning tasks that do not require the
back-and-forth motion--such as in tight spaces (e.g., around table
legs, chairs, and the like) and/or during scrubbing tasks. As used
herein, scrubbing tasks are intended to define tasks that require
the user to apply an additional force along the axis (A) to
increase the localized force between tool 18 and the surface being
cleaned.
[0059] Here, use of stationary portion 12 of both handles 20, 22
provides the user increased control of tool 18, which can be
particularly useful in tight spaces and scrubbing tasks. Again, the
ease with which the user can switch between grasping stationary
portion 12 and rotational portion 14 on each of handles 20, 22
provides increased ease than previously possible.
[0060] Although various attributes of assembly are described herein
with respect to different embodiments, it is contemplated by the
present disclosure for the assembly to include any of the
attributes described herein in any desired combination.
[0061] It should also be noted that the terms "first", "second",
"third", "upper", "lower", "front", "back", and the like may be
used herein to modify various elements. These modifiers do not
imply a spatial, sequential, or hierarchical order to the modified
elements unless specifically stated.
[0062] While the present disclosure has been described with
reference to one or more exemplary embodiments, it will be
understood by those skilled in the art that various changes may be
made and equivalents may be substituted for elements thereof
without departing from the scope of the present disclosure. In
addition, many modifications may be made to adapt a particular
situation or material to the teachings of the disclosure without
departing from the scope thereof. Therefore, it is intended that
the present disclosure not be limited to the particular
embodiment(s) disclosed as the best mode contemplated.
