This Application claims priority under the Paris Convention to United Kingdom Patent Application No. 1912140.9, filed Aug. 23, 2019, the entire content of which is herein incorporated.
Not Applicable
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.
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.
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.
Objects and aspects of the present invention seek to alleviate at least these problems with the prior art.
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.
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.
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.

An embodiment of the present invention will now be described by way of example only and with reference to the accompanying drawings, in which:
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.
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.
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.
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
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.
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.
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.
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.
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 snapfit clip 190 for attaching to a mop handle 50. The snap-fit clip 190 comprises two wings 200 which are resiliently deformable.
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.
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.
The lever 170 further comprises a protrusion or hook 230 which extends from the 30 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.
In use, the user can attach and detach mop material from the mop head 10 as detailed hereinafter.
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.
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.
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.
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.
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.
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.
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.
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.
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.
