Definitions

  • the present invention is directed toward mops, and more specifically, is in the field of butterfly mops.
  • a butterfly mop is characterized in that it comprises an elongate, foldable, compressible, liquid-absorbent member, such as a sponge, which is disposed at one end of a mop shaft, and which is used to absorb liquid, typically water, from a surface.
  • an elongate, foldable, compressible, liquid-absorbent member such as a sponge
  • which is disposed at one end of a mop shaft
  • liquid typically water
  • 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 motion of the wings of a butterfly.
  • the butterfly mop includes an 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 compress the liquid absorbent member within a compression space disposed between and defined by the dual arms of the track.
  • Similar butterfly mops are shown in the US 5,131,111 A, CA 767,342 A and in GB 932,579.
  • a common problem with conventional butterfly mops is the difficulty inherent in manually applying sufficient 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 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 one mop often will not fit on a second mop, and thus retailers must stock many different sizes of mop elements.
  • the invention overcomes these drawbacks by providing a mop according to claim 1.
  • the channel body uniquely cooperates with an elongate mop element comprising a foldable, compressible liquid absorbent member.
  • the channel body and mop element disposed in a relatively hinged relationship with respect to one another along a hinge line lying along a longitudinal axis of the mop element.
  • the mop element and 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 rotated to a position within the channel.
  • a tension rod 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.
  • the liquid absorbent member 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 the butterfly action of the absorbent member provides a leveraged relationship that effectively multiplies the force applied 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 channel to thereby expel liquid therefrom.
  • the actuating handle is pivotally mounted to the shaft about a pivot axis, and comprises an elongate member terminating in an operator gripping portion, whereby a pivotal motion of the gripping portion relative to the shaft creates tension in the rod.
  • the mop includes a mop element support having a first wing, and a second wing, and a link portion supported on the body and including a liquid absorbent mop element mounted on the wings.
  • the first leg portion of the channel body includes a first roller rotatably journalled thereto and engaging the first wing
  • 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.
  • the mop element includes a compressible 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 maintain the inner layer against the support.
  • 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.
  • the mop element By so attaching the mop element to the mop element support, the mop element may be quickly and easily removed when 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.
  • the butterfly mop 20 generally includes a mop shaft 21 having a mopping end 22 and a gripping end 24. Disposed at the mopping end 22 is a mop element assembly 25 including a mop element 26 and a mop element support 27.
  • the mop element 26 includes an absorbent member of spongy material as shown in Fig. 1 and a flexible, relatively tough inner layer (not shown in Fig. 1) which is secured to the support 27 by fasteners 76, 77.
  • a hanger clip 29 for supporting the mop for storage.
  • the mop element 26 comprises a flexible, compressible absorbent member which absorbs liquid and from which liquid may be expelled upon compression thereof.
  • the mop element has a longitudinal axis 31 and a central transverse axis 32 generally perpendicular to the longitudinal axis 31.
  • the central axis 32 divides the mop element generally into two regions, a first region 34 and a second region 35.
  • the mop element is disposed on the mop element support 27, which support comprises a first wing 37 and a second wing 38 generally coinciding with respective regions 34, 35 of the mop element 26. As shown more particularly in Fig.
  • the support 27 includes a link 40 connected to the wings 37, 38 such that the wings are hingedly secured to first and second link arms 42, 43, respectively.
  • the support further includes biasing means for urging the wings and the respective mop element regions toward longitudinally aligned positions.
  • the biasing means comprises a dual coiled spring 45 having first and second legs 47, 48 (shown in phantom in Fig. 4) engaging the respective wings 37, 38.
  • the biasing means may comprise two single coil springs (not shown) or another suitable spring mechanism.
  • the mop further includes a channel body 50, as shown, for example, in Figs. 1, 3, and 4.
  • the channel body 50 includes a first leg 51 and a second leg 52 connected by a bight portion 54, and a channel 55 generally defined by a space between the first leg 51 and the second leg 52.
  • First and second rollers 58, 59 are rotatably journalled respectively on the first and second legs 51, 52 and positioned continuously to engage 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.
  • the mop element 26 is disposed in a relatively hinged relationship with respect to the channel body 50.
  • 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, 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 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.
  • the 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.
  • the handle 69 is generally elongate and includes an operator 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.
  • Figs. 4-6 Operation of the mop is progressively illustrated in the plan views of Figs. 4-6 and in the side view of Fig. 7.
  • the mop element is shown in a mopping position in Fig. 4.
  • tension is applied to the tension rod 68 (shown in Figs. 5 and 6) whereupon the mop element 26 begins to fold along 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
  • Figs. 6 and 7 illustrate the mop element when fully withdrawn into the channel body.
  • the wings 37, 38 travel in a complex path including a generally arcuate path, as illustrated by arrow 74 in Fig. 7.
  • 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 which are secured in threaded apertures in the inner layer of the mop element 26.
  • the operator handle 69 is pivotally mounted to the shaft 21 at the pivotal mounting 79 as shown, for example, in Fig. 1.
  • the tension 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 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 handle 69' at pivot 73'.
