Abstract
A butterfly sponge mop (1) which has a mop handle (2) which can be set at a desired angle with respect to the wings (12,14) of the mop. The handle is attached to a swivel housing (34) which is provided between the wings, by a swivel connector (32) provided with a swivel pin (38). The axis of the swivel pin is at an angle to the axis of the handle so that rotation of the handle and swivel connector sets the angle of the handle.
Description




FIELD OF THE INVENTION




The present invention relates to sponge mops, and more particularly to “butterfly” type sponge mops.




BACKGROUND OF THE INVENTION




Conventional butterfly sponge mops include an elongate handle, a mop head comprising a sponge mounted on a pair of pivotable horizontal coplanar wings, and a squeeze mechanism for pivoting the wings into a vertical parallel position to compress the sponge and extract liquid therefrom. Typically, the mop head is mounted transverse to one end of the handle at a fixed angle to the axis of the handle. This is disadvantageous in that the head can only conform with a surface for efficacious mopping if the handle is maintained at a fixed angle to the surface. Furthermore, because the head is held at a fixed angle, it takes up a large amount of space when packaged or hung off supermarket shelves.




A possible solution to these problems is to allow the head to freely pivot at one end of the handle about an axis transverse to the axis of the handle. While this solution allows the head to freely pivot into conformity with a surface if the angle between the handle and the surface is varied, frictional forces parallel to the axis of the handle typically cause the head to freely pivot out of conformity with the surface during mopping. Additionally they may flop about during movement making the step of packaging into a box or hanging on a supermarket rack a more difficult exercise.




Conventional butterfly mops are therefore inefficacious in situations where ergonomics require variation of the angle between the handle and the surface during mopping. Such situations include the mopping of vertical surfaces, the mopping of elevated surfaces, and the mopping of surfaces under projections or with low overhangs.




In addition to the above disadvantageous functionality, conventional butterfly sponge mops are characterised by complicated squeeze mechanisms for extracting liquid from the sponge and complicated and inefficient arrangements for mounting the sponge on the head.




A requirement accordingly exists for a butterfly sponge mop wherein the head can be positively adjusted to a desired angle during mopping, and wherein both the squeeze mechanism and the sponge mounting arrangement are simple in construction and efficient in operation.




DISCLOSURE OF THE INVENTION




According to the present invention, there is provided a butterfly sponge mop including:




a mop handle;




a mop head comprising a pair of pivotable wings including means for holding the wings in a common plane;




means for mounting a sponge on the wings;




a squeeze mechanism for pivoting the wings to compress the sponge therebetween; and




a swivel assembly for rotatably connecting one end of the handle to the head such that the rotational configuration of the handle with respect to the head sets the relative angle made between the handle and the common plane.




Suitably the wings are of a generally planar configuration. They may be resiliently biased towards a coplaner position for mopping.




Advantageously, the swivel assembly includes a swivel connector and a swivel housing. The swivel connector advantageously has a front end and a rear end. The rear end includes a handle mounting socket and the front end includes a swivel pin. The handle mounting socket is angularly offset from the swivel pin. Conveniently, one end of the handle is retained against rotation in the handle mounting socket. Advantageously, the swivel housing includes a swivel socket portion and an disposed elongate body portion. The swivel socket portion may be angularly offset from the longitudinal axis of the body portion. The swivel socket portion advantageously has an unrestricted rear opening and a restricted front opening. The swivel connector is suitably received in the unrestricted rear opening such that swivel pin of the swivel connector extends through the restricted front opening of the swivel socket portion. Conveniently, the swivel pin is locked against the restricted front opening such that the swivel connector is freely rotatable but axially secured to the swivel socket portion of the swivel housing. Advantageously, the body portion of the swivel housing has a generally lower surface for mounting the pivotable wings such that the pivot axis of the wings is parallel to the longitudinal axis of the body portion.




As described above, the swivel connector and the swivel housing rotatably connect one end of the handle to the head such that the head can be conformed to a surface by relative rotation of the head and the handle if the angle between the handle and the surface is varied during mopping.




Advantageously, the squeeze mechanism includes an actuator sleeve and a compression clevis. The actuator sleeve is advantageously coaxially slidably mounted on the handle. The compression clevis is generally U-shaped and advantageously comprises a cross member having two fingers disposed normal thereto and extending from each of its ends. Conveniently, each finger of the compression clevis has a cam-like lower abutment surface. The free ends of the fingers of the compression clevis are advantageously pivotably connected to the body portion of the swivel housing about a pivot axis transverse to the longitudinal axis of the body portion such that the cam-like lower abutment surfaces of the fingers are proximate to the upper surfaces of the wings. Advantageously, the actuator sleeve is operatively connected to the compression clevis by a control member having a first end and a second opposite end, the second end being angularly offset from the first end. The first end of the control member is advantageously pivotably connected to the actuator sleeve about a pivot axis transverse to the axis of the handle, and the second opposite end of the control member is advantageously pivotably connected to the cross member of the compression clevis about a pivot axis parallel to the pivot axis of the fingers. Conveniently, the angular offset between the first and second opposite ends of the control rod accommodates angular displacement of the compression clevis relative to the actuator sleeve when the handle is rotated relative to the head to conform the head to a surface during mopping.




As described above, the squeeze mechanism is operable to simultaneously pivot the wings from the horizontal coplanar mopping position to a squeezing position where they are parallel for compressing the sponge and extracting liquid therefrom. Specifically, movement of the actuator sleeve towards the head causes the control member to concomitantly move towards the cross member of the compression clevis, which in turn causes the fingers of the compression clevis to pivot such that the cam-like lower abutment surfaces of the fingers abut the upper surfaces of the wings in a camming motion to simultaneously pivot the wings into a vertical parallel position.




Advantageously, the wings are configured such that the head defines a trapezoidal plan shape to facilitate mopping in corners and/or confined spaces. Further or in the alternative, the upper surfaces of the wings may be bevelled for this purpose.




Advantageously, the sponge is generally identical in plan shape to the head and has an upper surface and a lower surface. The sponge is advantageously removably mounted on the lower surfaces of the wings by mounting plates secured to the upper surface of the sponge that are slidably lockable in complementary key structures formed on the lower surfaces of each wing. Conveniently, a key structure is formed on the lower surface of each wing generally parallel to the pivot axis of the wings, and two mounting plates are secured to the upper surface of the sponge in aligned spaced apart relationship transverse to the longitudinal axis of the sponge. Preferably, each key structure includes a recess formed in the front edge of the respective wing and each mounting plate includes a complementary locking tab arranged adjacent the corresponding front edge of the sponge.




As described above, the sponge is removably mounted on the lower surface of the wings by simultaneously sliding the respective mounting plates on the sponge into the respective key structures on the lower surfaces of the wings until the locking tabs on the mounting plates are lockably received in the complementary recesses in the wings.




Advantageously, an auxiliary cleaning tool, such as a scouring pad or a squeegee, is selectively removably mounted on the front of the body portion of the swivel housing. The auxiliary cleaning tool is advantageously removably mounted by a mounting plate provided on the auxiliary cleaning tool that is slidably lockable in a complementary key structure formed in the front of the body portion. Conveniently, the key structure is formed in the front of the body portion perpendicular to the longitudinal axis of the body portion. The mounting plate is advantageously arranged on the auxiliary cleaning tool such that the operative face of the auxiliary cleaning tool is parallel to the head when the mounting plate is slidably locked in the complementary key structure. As with the head, the operative face of the auxiliary cleaning tool, such as the blade of a squeegee, may be conformed to a surface by relative rotation of the handle and the head during cleaning.




An embodiment of the invention will now be described by way of example only with reference to the accompanying drawings, in which:

,


14


and the mounting plates


16


,


18


include complementary locking tabs


28


,


30


arranged adjacent the corresponding front edge of the sponge


6


. It will be appreciated from the above description that the sponge


6


is removably mounted on the lower surfaces of the wings


12


,


14


by simultaneously sliding the respective mounting plates


16


,


18


into the respective key structures


20


,


22


until the locking tabs


28


,


30


are lockably received in the complementary locking recesses


24


,


26


.




The head


4


is rotatably connected to one end of the handle


2


at an angle to the longitudinal axis of the handle


2


by a swivel assembly


8


. The angle may be varied with rotation of the handle relative to the head. It may be adjusted so that the relative angle between the handle and plane of the extended wings is reduced to reduce the overall bulk of the mop to facilitate packaging. The angle may be reduced to 25 degrees or even less. The swivel assembly


8


generally comprises a swivel connector


32


and a swivel housing


34


. As illustrated in

FIG. 4

, the swivel connector


32


is generally cylindrical and has a rear end including a generally cylindrical handle mounting socket


36


and a front end including a swivel pin


38


that is angularly offset from the handle mounting socket


36


. One end of the handle


2


is retained against rotation in the handle mounting socket


36


by conventional releasable fastening means (not shown), such as a screw or rivet.




The swivel housing


34


includes a horizontally disposed elongate body portion


40


and a generally cylindrical swivel socket portion


42


angularly offset from the longitudinal axis of the body portion


40


. The swivel socket portion

38


. As thus arranged, the swivel connector


32


is freely rotatable but axially secured to the swivel socket portion


42


of the swivel housing


34


. The body portion


40


of the swivel housing


34


has a generally planar lower surface and the pivotable wings


12


,


14


are mounted thereto such that the pivot axis A-A of the wings is parallel to the longitudinal axis of the body portion


40


.




The swivel connector


32

rotatably connects one end of the handle


2


to the head


4


at an angle such that relative rotation of the handle


2


and the head


4


about the swivel assembly


8


varies the relative angle of the handle


2


and the head


4


as illustrated in FIG.


2


. It will be further appreciated that the swivel assembly


8


facilitates efficacious mopping by allowing the head


4


to be positively conformed to a surface in situations where ergonomics require variation of the angle between the handle


2


and the surface during mopping. Such situations include the mopping of walls and windows, the mopping of ceilings, the mopping of stairs, and the mopping of floors under cupboards and under furniture with short legs.




The squeeze mechanism


10


generally comprises an actuator sleeve


50


, a control member


52


, and a compression clevis


54


. The actuator sleeve


50


is coaxially slidably mounted on the handle


2


for telescopic movement therewith and the generally U-shaped compression clevis


54


comprises a cross member


56


having two fingers


58


,


60


disposed normal thereto and extending from each of its ends. Advantageously, each finger


58

34


about a pivot axis B-B transverse to the pivot axis A-A of the wings


12


,


14


such that the cam-like lower abutment surfaces


62


of the fingers


58


,


60


are proximate to the upper surfaces of the wings


12


,


14


.




The actuator sleeve


50


is operatively connected to the compression clevis


54


by the control member


52


. The control member


52


advantageously comprises a metal rod and has a first end


64


and a second opposite end


66


angularly offset from the first end


64


. The first end


64


of the control member


52


is pivotably connected to the actuator sleeve


50


about a pivot axis C-C transverse to the axis of the handle, aid the second end


66

to accommodate angular displacement of the compression clevis


54


relative to the actuator sleeve


50


when the handle


2


is rotated relative to the head


4


to positively conform the head


4


to a surface during mopping.




It will he appreciated from the above description that the squeeze mechanism


10


is operable to simultaneously pivot the wings


12


,


14


from the horizontal coplanar mopping position to a vertical parallel position (illustrated in outline in

FIGS. 2 and 5

) for compressing the sponge and extracting liquid therefrom. As illustrated in

FIG. 2

, movement of the actuator sleeve


50


towards the head


4


causes the control member


52


to concomitantly move towards the cross member


56


of the compression clevis


54


, which in turn causes the fingers


58


,


60


of the compression clevis


54


to pivot about pivot axis B-B such that the cam-like lower abutment surfaces


62


of the fingers


58


,


60


abut the upper surfaces of the wings


12


,


14


in a camming motion to simultaneously pivot the wings


12


,


14


in the direction of the arrows illustrated in

FIG. 5

into a vertical parallel position. It will be appreciated that the when the above operation is reversed, the wings


12


,


14


will be returned to the horizontal coplanar mopping position by the spring (not shown) arranged transverse to pivot axis A-A that resiliently interconnects the upper surfaces of the wings


12


,


14


.




The illustrated embodiment of the present invention also includes means for selectively mounting an auxiliary cleaning tool


70


, such as a scourer or a squeegee, on the front of the body portion


40


of the swivel housing


34


. As illustrated in

FIGS. 4 and 7

, the auxiliary cleaning tool


70


is mounted by a mounting plate


72


provided on the auxiliary cleaning tool


70


that is slidably lockable in a complementary key structure


74


formed in the front of the body portion


40


. The key structure


74


is formed in the front of the body portion


40


perpendicular to the longitudinal axis of the body portion


40


. The mounting plate


72


is arranged on the auxiliary cleaning tool


70


such that the operative face of the auxiliary cleaning tool


70


is parallel to the head


4


when the mounting plate


72


is slidably locked in the key structure


74


. The key structure


74


is advantageously moulded of a plastic material such as polypropylene or polyethylene and may be designed and configured to positively permanently snap-fit to the body portion


40


of the swivel housing


34


. It will he appreciated that the operative face of the auxiliary cleaning tool

on the pins


908


and


910


to rotatably secure the pins within the connector as well.




The snap fit elements


410


on the clip snap fit into the locking recesses


618


provided on either side of the housing to lock the clip within the housing.




Finally, the sponge which has been secured to sponge mounting plates


350


is secured underneath the wings by sliding the mounting plates into positions such that the slidable mounting tabs


352


,


354


and


356


cooperate with the locking tabs


607


and the front locking tab


358


snap fits behind the upper forward edge of the opening


606


. As the fully constructed pivot mop assembly functions in substantially the same way as the assembly described with reference to

FIGS. 1

to


7


, the actual functioning of the mop will not be described any further.




In view of the above description, it will be appreciated that the preferred embodiments of the present invention provide a butterfly sponge mop wherein the head can be positively conformed to a surface for efficacious mopping if the relative angle of the handle and the head is varied during mopping, and wherein both the squeeze mechanism and the sponge mounting arrangement are simple in construction and efficient in operation.




The above embodiments has been described by way of example only and modifications are possible within the scope of the invention disclosed.

A butterfly sponge mop including:a mop handle having an axis; a mop head having a pair of pivotable wings including means for holding the wings in a common plane; means for mounting a sponge on the wings; a squeeze mechanism for pivoting the wings to compress the sponge therebetween; and a swivel assembly rotatably connecting one end of the handle to the head, the assembly including a swivel connector defining a central axis the swivel connector being pivotably mounted in a swivel housing portion so as to rotate about and define an axis of rotation wherein the central axis is angled from the axis of rotation and the axis of rotation is offset relative to the axis of the handle and relative to the common plane wherein the rotational configuration of the handle with respect to the head sets the relative transverse angle made between the handle and the common plane regardless of the position of the mop handle relative to the common plane.
  • 2. A butterfly sponge mop according to claim 1 wherein the wings include resilient means for biasing them to a coplanar position.
  • 3. A butterfly sponge mop according to claim 1 wherein the relative angle made between the handle and the common plane may be adjusted by rotation of the handle such that it is less than twenty five degrees.
  • 4. A butterfly sponge mop according to claim 1 wherein the squeeze mechanism includes:an actuator slidably mounted on the handle and connected via a control member to a compression mechanism; a pair of opposed fingers each provided with an abutment surface; and a corresponding abutment surface provided on each wing for cooperating with the respective abutment surface on each finger; the construction of the mop being such that sliding of the actuator in the direction of the mop head causes the abutment surfaces on the respective fingers to push against the corresponding abutment surfaces on the wings to pivot the wings towards each other thereby squeezing the sponge therebetween.
  • 5. A butterfly sponge mop according to claim 4 wherein the control member has a first end and a second opposite end, the second end being angularly offset from the first end to accommodate angular displacement of a compression clevis including the opposed fingers when the handle is rotated with respect to the head.
  • 6. A butterfly sponge mop according to claim 1 wherein the means for mounting a sponge on the wings includes:a key structure formed on the lower surfaces of each wing; and a mounting plate for each wing attached to the sponge, and each mounting plate is adapted to cooperate with the key structure on a respective wing to secure the sponge to the wings.
  • 7. A butterfly sponge mop according to claim 6 wherein the key structures each include a recess formed on the respective wing, and each mounting plate includes a complementary locking tab arranged to cooperate with the corresponding recess to lock the mounting plate in position underneath the respective wing.
  • 8. A butterfly mop according to claim 6 wherein the squeeze mechanism includes:an actuator coaxially slidably mounted on the handle and connected via a control member to a compression mechanism; a pair of opposed fingers each provided with an abutment surface; and a corresponding abutment surface provided on each wing for cooperating with the respective abutment surface on each finger; the construction being such that sliding of the actuator in the direction of the mop head causes the abutment surfaces on the respective fingers to push against the corresponding abutment surfaces on the wings to pivot the wings towards each other thereby squeezing the sponge therebetween.
  • 9. A butterfly sponge mop according to claim 1 wherein the swivel housing portion includes:a swivel housing: and the swivel connector attached to the handle and the swivel housing in such a manner as to allow relative rotation between the swivel housing and handle.
  • 10. A butterfly sponge mop according to claim 9 wherein the swivel connector includes a swivel pin rotationally secured to the swivel housing portion in such a manner that the rotation of the swivel pin with respect to the swivel housing portion defines said axis of rotation which is angularly offset with respect to the handle.
  • 11. A butterfly mop according to claim 10 wherein the swivel pin is held within the swivel housing portion by a clip member which snap fits within the swivel housing to cooperate with the swivel pin whereby to rotatably secure the swivel pin within the swivel housing portion.
  • 12. A butterfly sponge mop including:a mop handle having an axis: a mop head having a pair of pivotable wings including means for holding the wings in a common plane; means for mounting a sponge on the wings; a squeeze mechanism for pivoting the wings to compress the sponge therebetween and comprising an actuator slidably mounted on the mop handle, a control member and a compression mechanism, the control member connecting the actuator to the compression mechanism; and a swivel assembly for rotatably connecting one end of the handle to the head, the assembly including a swivel connector defining a central axis the swivel connector being pivotably mounted in a swivel housing portion so as to rotate about and define an axis of rotation wherein the central axis is angled from the axis of rotation and the axis of rotation is offset relative to the axis of the handle and relative to the common plane wherein the rotational configuration of the handle with respect to the head sets the relative transverse angle made between the handle and the common plane regardless of the position of the mop handle relative to the common plane.
