Field of the Invention
[0001] The present invention relates to a mop head, and in particular, to a mop head comprising
a lever connected to the mop head by pivot.
Background of the Invention
[0002] Mops which removably retain mop materials are commonly used to clean floors in commercial,
industrial, office and residential spaces. In particular, the mop head of the mop
securely retains and holds the mop material, such that the absorbent mop material
can be used by the user to clean the floor. Typically, the mop head comprises the
mechanism from removably retaining the mop material and provides a portion to which
a mop handle can be connected.
[0003] However, some problems exist with current mop heads. For example, mop heads often
comprise complex mechanisms for securing the mop material. These complex mechanisms
can often can become damaged with use of the mop or from drying the mop material with
wringers. Further, these complex mechanisms are often difficult to clean and remove
the build-up of dirt or grime. Secondly, removal and replacement of the mop material
from the mop head can often require the user to touch the soiled mop material itself,
which is undesirable and unhygienic. Thirdly, the mechanism for fastening mop material
to the mop head is often reliant on a component or property of the mop material itself,
for example, the mop material having a pocket or hook. This is undesirable as the
mop material can quickly become damaged, distorted or worn through use.
[0004] Objects and aspects of the present invention seek to alleviate at least these problems
with the prior art.
Summary of the Invention
[0005] According to the present invention, there is provided a mop head. The mop head comprises
a body member for attaching to a mop handle. The body member is connected to a fastening
member by a hinge. The fastening member is moveable about the hinge between a closed
position for retaining mop material and an open position for attaching and detaching
mop material. The mop head further comprises a lever connected to the body member
at a pivot. The lever is arranged to move about the pivot between an engaged position
where the lever is engaged with and retains the fastening member in the closed position
and a disengaged position where the lever is disengaged from the fastening member.
[0006] The present invention is advantageous in that a lever is used to secure the fastening
member in the closed position. The nature of a lever is that it can be positioned
and designed such that it is spaced from the mop material and operated without touching
mop material. Therefore, the lever can be moved to the disengaged position releasing
the retained mop material without the user touching a part of the mop head or mop
material which may have become soiled through use. Further, a lever and pivot are
less complex that many mechanisms used to retain mop material. The simplicity and
elegance of lever and pivot increases the robustness, durability and lifespan of the
mop head.
[0007] Another advantage of the mop head of the present invention is that mop material can
be retained directly by the mop head by the action of the lever on the fastening member.
Therefore, the mop head is not reliant on the mop material comprising any specific
components to enable the attachment and can be used with a variety of mop materials.

Figure 4 is a side-on view of the mop head of Figure 1, where the fastening member
is in the closed position and the lever is in the engaged position.
[0033] Figures 1 to 4 depict views of an embodiment of a mop head 10 in accordance with
the present invention. The mop head 10 comprises a body member 20 and a fastening
member 30. In use, the mop head 10 retains mop material for cleaning surfaces, such
as floors, by securely attaching or fixing the mop material in between the body member
20 and the fastening member 30.
[0034] The body member 20 comprises a handle portion 40 for accepting and securely retaining
a detachable mop handle 50. The handle portion 40 is substantially cylindrical and
at one end comprises a cavity for securely retaining the mop handle 50 by a screw
thread.
[0035] The body member 20 further comprises a main portion 60 which is substantially cuboid
and extends from the handle section 40 to a base portion 70. The base portion 70 is
also substantially cuboid. The longitudinal axes of the cuboid main portion 60 and
base portion 70 are substantially perpendicular, where the longitudinal axis of the
main portion 60 is parallel and collinear with the longitudinal axis of the attached
mop handle 50. The base portion 70 has a width and thickness greater than the main
portion 60 and resembles a cuboid lip or rim outwardly extending from an end of the
main portion 60.
[0036] Proximate with a first edge 80 of the base portion 70 is a hinge 90. The rotational
axis of the hinge 90 is adjacent to the first edge 80 of the base portion 70 and lies
in a direction parallel with the first edge 80. Further, the hinge 90 is centrally
aligned with the first edge 80. The first edge 80 of the base portion 70 comprises
a cut-out section 85 for accommodating the hinge 90.
[0037] The fastening member 30 which is pivotally attached to the hinge 90 such that the
fastening member 30 can rotationally move about the hinge 90 and depend from it. The
fastening member 30 comprises an angled section 100 which is substantially curved
and right-angled. The angled section 100 extends between the hinge 90 and a fastening
section 110 of the fastening member 30. In Figure 1 and Figure 2 the fastening member
is located in the open position, where mop material can be placed or removed from
between the body member 20 and fastening member 30 for attachment or detachment.
[0038] The fastening section 110 is substantially cuboid with rounded corners and comprises
a substantially planar face 120 for engaging the underside 125 of the base portion
70 of the body member 20 and securing the mop material. The fastening section 110
is smaller than the base portion 70. From one end of the fastening section 110 extends
the angled section 100 and the opposing end of the fastening section 110 comprises
an aperture 130 proximate the edge. The aperture 130 extends from the planar face
120 completely through the fastening member 30 and has a cross-section which is substantially
rectangular.
[0039] Further, from the face of the fastening member 30 opposing the planar face 120 extends
a series of movement protuberances 135. The movement protuberances 135 extend from
the fastening member 30 from a position proximate the angled section 100 in a direction
substantially perpendicular to the plane occupied by the planar face 120.
[0040] The planar face 120 of the fastening member 30 further comprises two cavities 140
for accepting and accommodating two foot members 150 which extend from the underside
125 of the base portion 70. The cavities 140 and the foot members 150 are complementarily
sized and shaped.
[0041] The base portion 70 comprises a second edge 155 which is located on the opposing
side of the base portion 70 to the first edge 80 and is substantially parallel with
the first edge 80. Proximate the second edge 155 is a pivot 160, where the pivot 160
is accommodated within a cut-out section 165 of the second edge 155.
[0042] Pivotally attached to the pivot 160 is the lever 170 such that the lever 170 can
be rotated about the pivot 160. The lever 170 comprises a handle portion 180 which
extends from the attachment at the pivot 160 away from the base portion 70. In this
way, the handle portion 180 is located on the opposite side of the base portion 70
to the fastening member 30. The top end of the lever 170 and handle portion 180 spaced
from the pivot 160 comprises fixing formation 185 for reversibly fixing the position
of the lever. In this embodiment, the fixing formation 185 comprises a snap-fit clip
190 for attaching to a mop handle 50. The snap-fit clip 190 comprises two wings 200
which are resiliently deformable.
[0043] In this embodiment, the wings 200 are symmetrical and resemble segments of a circle
such that the snap-fit clip 190 is substantially circular and resembles the circumference
of a major segment circle. Thus, the snap-fit clip 190 and wings 200 complement the
circular cross-section of the mop handle 50. The snap-fit clip 190 is arranged to
surround the majority of the mop handle 50 when reversibly attached to the mop handle
50.
[0044] The handle portion 180 further comprises a pair of identical projections 210 which
form part of a pair of stop formations 205 along with the two stop spaces 220. The
stop spaces 220 are indentations, recesses or cavities in opposing rectangular walls
of the main portion 60 of the body member 20. The stop spaces 220 extend from an edge
on the main portion 60 adjacent the lever 170. Each of the projections 210 extends
from the side of the lever 170 adjacent to the main portion 60 and is moveably accommodated
within one of the stop spaces 220.
[0045] The lever 170 further comprises a protrusion or hook 230 which extends from the portion
or end of lever 170 attached the pivot 160. The hook 230 has a narrow portion 235
which extends from proximate the pivot 160. The narrow portion 235 is complementary
to the thickness of fastening section 110 of the fastening member 30. The hook 230
further comprises a barb 240 and tapered surface 250. The tapered surface 250 extends
from the end of the hook 230 towards the pivot 160 and widens the hook 230 until it
maximum adjacent to the narrow portion 235. The barb 240 then extends between the
tapered surface 250 and the narrow portion 235 providing a planar engagement surface
260 for engaging the fastening member 30. The barb 240 and planar engagement surface
260 are substantially perpendicular with the longitudinal axis of the lever 170.
[0046] In use, the user can attach and detach mop material from the mop head 10 as detailed
hereinafter.
[0047] Figure 1 and Figure 2 depict the mop head 10 where the fastening member 30 is in
an open position and the lever 170 is in the disengaged position.
[0048] In the disengaged position the lever 170 is pivoted such that the longitudinal axis
of the lever 170 is angled with respect to and not parallel with the longitudinal
axis of the body member 20. The snap-fit clip 190 and wings 200 are not engaged with
and are spaced away from the mop handle 50. The lever 170 is prevented from pivoting
further than the disengaged position by the pair of stop formations 205. That is,
the pair of projections 210 of the stop formation 205 are accommodated within the
pair of stop spaces 220 of the stop formation 205. In the disengaged position the
projections 210 engage the edge of the stop space 220 proximate to the lever 170.
It is this engagement which prevents the lever 170 from being rotated than the disengaged
formation. The angle of the lever 170 in the disengaged formation angles the protrusion
230 and its features towards the fastening member 30 in its open position.
[0049] When the fastening member 30 is in this open position, the fastening member 30 depends
from the hinge 90 and can be rotated about the hinge 90 by the user's hands or through
contact of the movement protuberances 135 with a surface. The mop material to be attached
can be placed in between the body member 20 and the fastening member 30.
[0050] Figure 3 depicts the mop head 10 where the fastening member 30 is in the closed position.
The fastening member 30 can be moved from the open position of Figures 1 and 2 to
the closed position by rotating about the hinge 90. In the closed position angled
section 100 extends from the hinge 90 to proximate the underside 125 of the body member
20 and the fastening section 110 lies proximate and parallel to the underside 125
of the body member 20. In some embodiments, the planar face 120 and the underside
125 of the body member 20 substantially abut along their surfaces. In use, mop material
is attached to the mop head 10 by placing it in between the fastening member 30 and
the body member 20 in the open position and then moving the fastening member 30 towards
its the closed position. In the closed position the mop material is then securely
engaged between the fastening member 30 and the underside 125 of the body member 20.
[0051] Further, in the closed position, the cavities 140 of the fastening member 30 accommodate
the foot members 150 of the body member 20. In use, the accommodation of the foot
members 150 within the cavities 140 helps to securely and frictionally engage the
mop material as the mop material is forced partial within the cavities 140.
[0052] In moving the fastening member 30 to the closed position, the hook 230 of the lever
170 is inserted in and through the aperture 130 of the fastening member 30. The angle
of the tapered surface 240, when the lever 170 is in the disengaged position, allows
the hook 230 to be inserted into the aperture 130 without any engagement between the
parts. That is, without the tapered surface 240 the hook 230 would have to smaller
or aperture 130 would have to be larger. Further, the tapered surface 240 helps to
insert the hook 230 into the aperture 130 when the lever 170 is located at an intermediate
position by frictionally forcing the lever 170 towards the disengaged position from
the intermediate position.
[0053] The stop formation 210 dictates the angle and position of the lever 170 and hook
230 in the disengaged position. Therefore, the configuration of the stop formation
210 is also important in controlling the interplay between the hook 230 and the aperture
130 when the fastening member 30 is moved from the open position to the closed position.
[0054] Figure 4 depicts the mop head 10 when the fastening member 30 is in the closed position
and the lever 130 has been moved into the engaged position.
[0055] In the engaged position the snap-fit clip 190 and its wings 200 reversibly engage
and are attached to the mop handle 50. In use, the snap-fit clip 190 is attached to
the mop handle 50 by applying a force to the snap-fit clip 190 which resiliently deforms
the snap-fit clip 190.
[0056] Further, in the engaged formation the hook 230 extends through the aperture 130.
In particular, the narrow portion 235 extends through the aperture 130 and the barb
240 engages the underside on the fastening section 110. The planar engagement surface
260 of the barb 240 engages the fastening member 30 such that the fastening member
30 is securely locked in the closed position. In this way, the aperture 130 and hook
230 form a locking formation 270 for locking the fastening member 30 in the closed
position, where the locking formation 270 is locked and unlocked by movement of the
lever 170. Thus, the mop material positioned between the body member 20 and the fastening
member 30 is securely attached to the mop head 10 and be used to clean a surface.
[0057] Finally, in the engaged position the projection 210 of the stop formation 205 engages
the side of the stop space 220 furthest from the lever 170. The stop formation 205
prevents the lever from being rotated past the engaged position. This is beneficial
as it prevents potential to damage the hook 230 and hinge 90 by pulling the fastening
member 30 too far. Also, the stop formation helps prevent damage to the snap-fit clip
190.
[0058] Only the process for attaching mop material has been detailed above. The process
for detaching mop material is simply the reverse of the attachment process. In short,
moving the lever 170 to the disengaged position from the engaged position by hand,
and then moving the fastening member 30 to the open position from the closed position
using the movement protuberances 135.
