member, such~as a sponge, which is disposed at one end of a mop shaft, and which is used to absorb liquid, typically 2o water, from a surface. When it is desired to expel liquid from the absorbent member, portions of the absorbent member are folded over one another along a transverse axis of the absorbent member and are compressed, using a folding mechanism such as a roller or track. Butterfly mops are so named because the folding and unfolding of the absorbent member along its transverse axis is said to resemble the 6s'~~',q .
r motion ofv the .wings of a, butterfly.
One typical butterfly mop is shown in U.S. Patent _ 2,892,201. As shown therein, the butterfly mop includes an 3o elongate liquid absorbent member, a plate connected to a surface of each "wing" of the liquid absorbent member, and an activating rod pivotally connected to a portion of each of the plates adjacent the other. plate. The plates are drawn along the dual arms of a yoke-like track to thereby fold the liquid absorbent member over onto itself and to a compress the liquid absorbent member within a compression space disposed between and defined by the dual anus of the track. Numerous other butterfly mops are known in the prior art.
A conenon problem with conventional butterfly mops is the difficulty inherent in manually applying sufficient s force to the actuating mechanism to fold the liquid absorbent member over onto itself and to compress the liquid absorbent member sufficiently to satisfactorily expel liquid therefrom. Indeed, in typical butterfly mops, substantial physical effort may be required to compress the io absorbent member. Another drawback lies in the difficulty of removing a spent liquid absorbent member and of attaching a new liquid absorbent member. Known absorbent . members-typically are sized to. be received by, and: supported on only one type of mop. A liquid absorbent member from ' is one mop often will not fit on a second mop, and thus retailers must stock many different sizes of mop elements.
It is a general object of the present invention to provide a mop that overcomes these drawbacks of earlier mops .
sY og ~ urvscrr=o~
The invention overcomes these, drawbacks by providing a mop including a channel body comprising spaced-apart first and second leg portions defining a channel therebetween.
2s The~channel body uniquely cooperates with an elongate mop element comprising a foldable, compressible liquid.
absorbent n~aber. In accordance with the invention, the channel body and mop element are disposed in a relatively hinged relationship with respect to one another along a 3-o hinge line lying along a longitudinal axis of the mop element. The mop element aad the channel body are relatively movable over a range of travel between an open mop element position and a closed position wherein the mop element is folded about a central transverse portion and is 3s rotated to a position within the channel. A tension rod 2 ' . connects a manually operable handle to the central portion of the mop element remote from the channel hinge portion for effecting relative hinged movement of the mop element and the channel body. When tension'is applied to the rod, the liquid absorbent member is drawn into the channel and is compressed therewithin to thereby expel water therefrom, the mop element folding about its transverse central portion upon compression. The relatively hinged relationship of the mop element and the channel body and la the butterfly action of the absorbent member provides a leveraged relationship that effectively multiplies the force aQplied by an operator to fold and compress the mop element. This leveraged relationship reduces the manual force necessary to draw the absorbent member into the i5 channel to thereby expel liquid therefrom. In accordance with preferred embodiments of the invention, the actuating handle is pivotally mounted to the. shaft about a pivot axis, and comprises an elongate member tez<ainating in an operator gripping portion, whereby a pivotal motion of the 2o gripping portion relative to the shaft creates tension in the rod.
In accordance with particularly preferred embodiments of the invention, the mop includes a mop element support having a first wing, and a second wing, and a link portion v"w'~ supported on the body and including a, liquid absorbent mop 2s ~
element mounted on the wings. In this embodiment, the first leg portion of. the channel body includes a first roller rotatably journalled thereto aad engaging the first wing, and the second leg .portion includes a second roller rotatably journalled thereto and engaging the second wing.
The rollers and wings serve to guide the liquid absorbent mop element into the channel.
In accordance with a highly preferred embodiment of the invention, the mop element includes a compressible 35 liquid absorbent outer layer and a flexible, relatively tough inner layer adapted to overlie the mop element support. The wings of the support are provided with apertures Which align respectively with apertures in the inner layer of the mop element. Fasteners are used to s maintain the inner layer against the support. Most preferably, the fasteners comprise a rivet portion having , an apertured head and a longitudinally slotted outer sleeve, and an inner pin portion having a headed end and an operative end opposite thereof. By introducing the io headed end of the pin portion into the slot of the rivet portion, the pin engages and enlarges the outer sleeve to removably retain the inner~layer and wing together. By so attaching the mop element to the mop element support, - the mop element may be quickly and easily removed when i5 spent, and may be readily replaced with a fresh mop element. The mop element may be provided with plural apertures sized to fit a variety of mop element supports.

First and second rollers 58, 59 are rotatably journalled respectively on the first and second legs 51, 52 and positioned continuously to engage 3o respectively the first and second wings 37, 38. The ' ' channel body 50 may be secured to the shaft by any suitable means, such as by fastener 56 as shown in Fig. 4.
In accordance with the invention, the mop element 26 is disposed in a relatively hinged relationship with 3s respect to the channel body 50. In a preferred embodiment, the link 40 of the mop element support 27 is connected to the channel body 50 at a trunnion 61, as illustrated in Fig. 4. The hinged mounting of the link 40 in the trunnion - 61 defines a hinge line 62 across the width of the link 40, s which hinge line is generally perpendicular to the transverse central axis 32 of the mop element 26. The hinged relationship between the mop element 26 and the channel body 50 and the wedging action as the wings 37, 38 are drawn between the rollers 58, 59 provides effective io multiplication of the force applied to the mop element 26 as it is drawn into the channel body 50, thus easing the wringing operation: . , Tabs disposed in the . wing may..
be provided to inhibit translation of the mop element along its longitudinal axis.
is An actuation mechanism 66 is provided for wringing the mop, as shown in Fig. 1. The actuation mechanism 66 preferably comprises a tension rod 68 having an 'operator end connected to a handle 69. As shown in Fig. 2, the handle 69 is generally elongate and includes an operator 20 gripping portion 71, a pivotal connection 73 to the tension rod 68 and a pivot 79 for connection to mop shaft (not shown in Fig.. 2). The tension rod is operatively connected to the mop element assembly 25, and preferably is connected to the mop element 26 via the mop element,support 27. By 2s applying tension to the tension rod 68, the operator causes the 'mop element 26 to move hingedly with respect to the channel body 50 and to be drawn into and compressed within the channel 55.
Operation of the mop is progressively illustrated in 3o the plan views of Figs. 4-6 and in the side view of Fig. 7.
The mop element is shown ~.n a mopping position in Fig. 4.
When it is desired to expel liquid from the mop element, ,, tension is applied to the tension rod 68 (shown in Figs. 5 and 6) whereupon the mop element 26 begins to fold along 3s the central transverse axis 32 and to be drawn into the channel body 50. Fig. 5. illustrates the mop element when partially drawn into the channel body, and Figs. 6 and 7 illustrate the mop element when fully withdrawn.into the channel body. During operation, the wings 37, 38 travel in a complex path including a generally arcuate path, as illustrated by arrow 74 in Fig. 7. In the embodiment , illustrated in Figs. 5 and 6, the mop element is secured to the mop element support with screw-type fasteners 76, 77 which pass through apertures in the wings 37 and 38 and io which are secured in threaded apertures in the inner layer of the mop element 2 6 .
The operator handle 69 is pivotally mounted to the pivotal mounting 79 as shown, for example, shaft 21 at the . ..n~_e .i.n Fig. 1. In the embodiment shown in Fig. 1, the tension is rod 68 has an eyelet 70 which extends around a shaped intermediate portion 30 of link 40 between arms 42,and 43.
The rod 68 is also secured to the handle 69 at a pivotal connection 73 disposed between the handle operator gripping portion and the pivotal mounting of the handle on the shaft 2o as a second order lever.
Fig. 11 illustrates an alternative embodiment of the mop 20~ of the invention utilizing a handle 69' having a central pivot point 79'. The tension rod 68' is disposed on the opposite end of the shaft 21' and is secured ~to the 2s handle 69' at pivot 73'. In this embodiment, the tension rod extends through an aperture 80' in the connecting 'portion 54' of the channel body 50'. The pivotal mounting 79' of the handle 69' to the shaft 21' is disposed between the operator gripping portion of the handle 69' and the 3o pivotal connection 73' of the handle 69' to the tension rod 68' as a first order lever. .
A preferred embodiment of the mop ~ element of the invention is illustrated in Fig. 8~. In this embodiment, the mop element 100 is a laminar structure, and comprises a as compressible liquid absorbent member 101 having a support WO 99/09876 PCT/US98/0063?
surface 102, which preferably is a generally planar surface. Overlying at least a portion of the support surface is a flexible, relatively tough inner layer 104, which preferably is made of plastic, such as polypropylene.
s The inner layer 104 is adapted to overlie a mop element . support 106 (partially shown in Fig. 8). The inner layer 106 may be continuous, but is preferably discontinuous across the central transverse aXis 107 of the mop element 100, and preferably includes spacing ribs 109 on at least a io portion thereof.
Many known mop elements designed for use with butterfly mops include two upwardly and inwardly extending threaded posts positioned for alignment with respective ~'~a;, l ement support. The mop element is holes in the mop e is secured to the support by inserting the posts into the aligned apertures and securing the post with a threaded cap. In accordance with the. present invention, the mop element 100 instead has at least one aperture, and preferably includes at least a pair of apertures 110, 111, zo which are positioned for alignment with respective holes 112, 113 in the mop element support. To secure the mop element to the support, a fastener, and preferably a pair of fasteners, are provided. Each fastener is separate from the mop element and includes a post portion for extending ('~.~~r through the aligned apertures in the ~ mop element and mop 2s element support, the fastener engaging the mop element and mop element support to thereby releasably secure the mop element to the support.
In accordance With one preferred embodiment of the 3o invention, the fasteners comprise removable rivets, such as those rivets sold under the trademark TUFLOK~ by ITW
Faster~. For example, as illustrated in Fig. 9, the removable rivet 120 comprises a rivet portion 121 and an inner plug portion 123. The rivet portion has a headed end 3s 124 and a longitudinally slotted outer sleeve 126 with an . inward annular projection 125 adjacent the slotted portion thereof. The inner plug has a head 128 and an operative tapered pin 129 opposite the head 128. The operative pin 129 of the plug 123 is inserted into the sleeve when the s headed portions 124, 128 of the respective rivet portion 121 and pin portion 123 are longitudinally spaced, and when the pin portion 123 is longitudinally moved toward the headed end 124 of the rivet portion 121. When the pin is partially extended through the sleeve 126, the pin engages io the inner annular projection 125 and enlarges the sleeve 126 to secure the rivet in place. Fig. 10 illustrates an embodiment of the mop of the invention wherein the mop element 100 is.secured to the mop element support 130 via i ~''"~

i5 limited to the foregoing types of fasteners, and indeed other fasteners can be used in conjunction with the invention. For example, it is contemplated that the aperture, in the mop element may include screw threads, and ' the fastener may include a shank portion having threads or 20 ~ other projections for engaging the screw threads in the mop element, thereby alloying the shank portion to be screwed and/or pushed into the aperture and thereby secured.
In accordance with a highly preferred embodiment of the invention, as shown in Fig. 8, the mop element 100 has 2s a central transverse axis 107 dividing the mop element into two regions 133, 134, and includes inner layer portions 104 having plural apertures in each region 133, 134. For example, the mop element 100 shown in Fig. 8 includes apertures I35, 136, which define a second pair of apertures 3o positioned for aligrmaeat with respective apertures 'in a second mopelement support (not shown). Thus, the mop element may be secured to mop, element supports. of various sizes. For example, in Fig. 8, apertures 110, 111 are aligned with respective apertures 112, 113 in the mop 35 element supports. However, it is contemplated that the pair of apertures 135, 136 could be used to secure the mop element 100 to a support having differently spaced apertures (not shown) which apertures align respectively with apertures 135, 136. The mop element shown in Fig. 8 further includes a third pair of apertures 137, 138 for . mounting to yet a third mop element support (not shown).
The mop element of the invention is not limited to the configuration shown. For example, the apertures in the mop element may be positioned in any location necessary for io alignment with respective apertures in any number of mop element supports. Similarly, while the fastener shown in Fig. 9 is the preferred embodiment of the fastener useful in conjunction with the invention,. it is contemplated that :'CNy. _ .
l ld b d Th e emp oye .
e mop other forms of fasteners cou I5 element and one or more fasteners may be provided in the form of a kit, the kit being adapted for securing the mop element to several differently sized mop element supports.
Thus, it is seen that the invention has overcome the drawbacks inherent in the prior art, and has achieved the 2o foregoing general objects. The relatively hinged relationships between the respective wings and between the mop element and the channel body allow a user readily to apply sufficient force to the actuating mechanism to fold .. . the liquid absorbing mop element over onto itself and to E-~;"-~~ compress the mop sufficiently to satisfactorily expel zs liquid therefrom. Moreover, the mop element and kit of the invention are versatile, and allow a single mop element to be supported on variously sized mop element supports.
Thus, a retailer need only carry one brand or type of mop 3o element, rather than different replacements for a variety . of mops.
While particular embodiments of the invention have been shown, it will be understood that the invention is not limited thereto since modifications may be made by those 35 skilled in the art, particularly in light of the foregoing teachings. It is, therefore, contemplated by the appended claims to cover any such modifications.as incorporate those features which constitute the essential features of these improvements within the true spirit and scope of the s invention.

The pivotal mounting 79' of the handle 69' to the shaft 21' is disposed between the operator gripping portion of the handle 69' and the 3o pivotal connection 73' of the handle 69' to the tension rod 68' as a first order lever. .
A preferred embodiment of the mop ~ element of the invention is illustrated in Fig. 8~. In this embodiment, the mop element 100 is a laminar structure, and comprises a as compressible liquid absorbent member 101 having a support WO 99/09876 PCT/US98/0063?
surface 102, which preferably is a generally planar surface. Overlying at least a portion of the support surface is a flexible, relatively tough inner layer 104, which preferably is made of plastic, such as polypropylene.
s The inner layer 104 is adapted to overlie a mop element . support 106 (partially shown in Fig. 8). The inner layer 106 may be continuous, but is preferably discontinuous across the central transverse aXis 107 of the mop element 100, and preferably includes spacing ribs 109 on at least a io portion thereof.
Many known mop elements designed for use with butterfly mops include two upwardly and inwardly extending threaded posts positioned for alignment with respective ~'~a;, l ement support. The mop element is holes in the mop e is secured to the support by inserting the posts into the aligned apertures and securing the post with a threaded cap. In accordance with the. present invention, the mop element 100 instead has at least one aperture, and preferably includes at least a pair of apertures 110, 111, zo which are positioned for alignment with respective holes 112, 113 in the mop element support. To secure the mop element to the support, a fastener, and preferably a pair of fasteners, are provided. Each fastener is separate from the mop element and includes a post portion for extending ('~.~~r through the aligned apertures in the ~ mop element and mop 2s element support, the fastener engaging the mop element and mop element support to thereby releasably secure the mop element to the support.
In accordance With one preferred embodiment of the 3o invention, the fasteners comprise removable rivets, such as those rivets sold under the trademark TUFLOK~ by ITW
Faster~. For example, as illustrated in Fig. 9, the removable rivet 120 comprises a rivet portion 121 and an inner plug portion 123. The rivet portion has a headed end 3s 124 and a longitudinally slotted outer sleeve 126 with an . inward annular projection 125 adjacent the slotted portion thereof. The inner plug has a head 128 and an operative tapered pin 129 opposite the head 128. The operative pin 129 of the plug 123 is inserted into the sleeve when the s headed portions 124, 128 of the respective rivet portion 121 and pin portion 123 are longitudinally spaced, and when the pin portion 123 is longitudinally moved toward the headed end 124 of the rivet portion 121. When the pin is partially extended through the sleeve 126, the pin engages io the inner annular projection 125 and enlarges the sleeve 126 to secure the rivet in place. Fig. 10 illustrates an embodiment of the mop of the invention wherein the mop element 100 is.secured to the mop element support 130 via i ~''"~
i h i .
nvent on e s not two removable rivets 131, 132. T
i5 limited to the foregoing types of fasteners, and indeed other fasteners can be used in conjunction with the invention. For example, it is contemplated that the aperture, in the mop element may include screw threads, and ' the fastener may include a shank portion having threads or 20 ~ other projections for engaging the screw threads in the mop element, thereby alloying the shank portion to be screwed and/or pushed into the aperture and thereby secured.
In accordance with a highly preferred embodiment of the invention, as shown in Fig. 8, the mop element 100 has 2s a central transverse axis 107 dividing the mop element into two regions 133, 134, and includes inner layer portions 104 having plural apertures in each region 133, 134. For example, the mop element 100 shown in Fig. 8 includes apertures I35, 136, which define a second pair of apertures 3o positioned for aligrmaeat with respective apertures 'in a second mopelement support (not shown). Thus, the mop element may be secured to mop, element supports. of various sizes. For example, in Fig. 8, apertures 110, 111 are aligned with respective apertures 112, 113 in the mop 35 element supports. However, it is contemplated that the pair of apertures 135, 136 could be used to secure the mop element 100 to a support having differently spaced apertures (not shown) which apertures align respectively with apertures 135, 136. The mop element shown in Fig. 8 further includes a third pair of apertures 137, 138 for . mounting to yet a third mop element support (not shown).
The mop element of the invention is not limited to the configuration shown. For example, the apertures in the mop element may be positioned in any location necessary for io alignment with respective apertures in any number of mop element supports. Similarly, while the fastener shown in Fig. 9 is the preferred embodiment of the fastener useful in conjunction with the invention,. it is contemplated that :'CNy. _ .
l ld b d Th e emp oye .
e mop other forms of fasteners cou I5 element and one or more fasteners may be provided in the form of a kit, the kit being adapted for securing the mop element to several differently sized mop element supports.
Thus, it is seen that the invention has overcome the drawbacks inherent in the prior art, and has achieved the 2o foregoing general objects. The relatively hinged relationships between the respective wings and between the mop element and the channel body allow a user readily to apply sufficient force to the actuating mechanism to fold .. . the liquid absorbing mop element over onto itself and to E-~;"-~~ compress the mop sufficiently to satisfactorily expel zs liquid therefrom. Moreover, the mop element and kit of the invention are versatile, and allow a single mop element to be supported on variously sized mop element supports.
Thus, a retailer need only carry one brand or type of mop 3o element, rather than different replacements for a variety . of mops.
While particular embodiments of the invention have been shown, it will be understood that the invention is not limited thereto since modifications may be made by those 35 skilled in the art, particularly in light of the foregoing teachings. It is, therefore, contemplated by the appended claims to cover any such modifications.as incorporate those features which constitute the essential features of these improvements within the true spirit and scope of the s invention.
