Description
MAC~INE WASHABL~ MOP SPONG~ 2040825 Field of the Invention This invention relates to the ~ield of household mops, and in particular to sponge mops having detachable sponges.
ackground of the Invention Currantly available household sponge mops have detachable mopping sponges. Typically the sponge has a backing plate affixed to it. The sponge backing plate may be secured to a flat plate, hereinafter referred to as a support plate, which is rigidly affixed to one end of the mop frame. The mop frame comprises, at one end, a struc-ture to rigidly support the support plate and~ at the other end, a mop handle.
The problem of how to detachably secure the sponge backing plate to the support plate, so that the sponge may be replaced once it becom s worn from use, has been addressed in the prior art. Typically a sponge bacXing plate may be detachably secured to the support plate by nipples which protrude orthogonally from the sponge backing plate for mating engagement with corre-sponding holes on the support plate, ox by nut and bolt or screw arrangements whereby both the sponge backing plate and the support plate have corresponding aligned holes for threaded engagement of a bolt or screw therethrough.
United States patent no. 4,882,804, which issued to Lucas on November 28, 1989, illustrates the use of a backing plate attached to one side of a sponge for removab-ly securable attachment of the backing plate to a supportplate. Plastic nipples on the backing plate mate with corresponding holes on the support plate.

Various means are taught in the prior art for attaching a backing plate to a sponge. Lucas teaches using a thermoplastic backing plate which is thermally sealed to a synthetic sponge. United States patent no. 4,817,228, which issued to von Meyer on April 4, 1989, teaches bond ing the sponge to the backing plate. United States patent no. 4,077,672, which issued to Clark, Jr. on March 7, 1978 teaches a method by which the backing plate is injection moulded onto the sponge.
The apparent need to use a backing plate irre-versibly attached to the sponge is a common drawback associated with the replaceable mop-heads for use on sponge mops. Because of the presence of the attached backing plate, the mop-head cannot be cleaned in conventional household laundry washing machines without risking marking or chipping the interior finish of the washiny machine drum. Consequently, replaceakle sponge mop-heads in the prior art have to be cleaned by hand or replaced with new mop-heads.
Sum,mary of the Invention It was recognized that what was needed was a means of attaching the sponge to the mop handle which would permit ready detachment of the sponge element, yet a secure attachment when the attachment was in place, and which, when the sponge element itself was detached, would include with the detached sponge element no solid metal portions or the like that could do damage to a washing machine service or the like when the sponge was being cleaned.
It was realized that this objective could be achieved by the use of two-component hook and loop type fas~ening material in strip form of the sort that is sold under the trademark VELCRO~

There are two preferred means of implementing the foregoing inventive concept.
In one preferred embodiment, the mop frame comprises as its lowermost element (when the mop is being used on a floor, for example) a metal OI- other solid rigid flange whose undersurface conforms to the top surface of the sponge and whose undersurface is provided with strip fastening material of the hook and loop type for mating with complementary strip fastening material adhered as by adhesive bonding to the top surface of the sponge.
According to the foregoing preferred embodiment, the sponge may be readily detached from the rigid flange 15 simply by disrupting the temporary bond afforded by the -~
hook and loop type fastening strips. The location of the strips and the fastening area are selected to be sufficient to ensure that the sponge is gripped firmly in place by the rigid flange of the mop frame when the mop i5 in use.
As an alternative preferred embodiment, the mop may terminate at its lower frame end in a conventional mop head support plate which is detachably securable to an intermediate sponge backing plate located between the mop head ~upport plate and the sponge. The means of attachment of the intermediate detachable backing plate can be nut and i~
bolt or otherwise conventional in character as described in prior art. However, according to my invention, the under-side of the intermediate sponge backing plate is bonded or otherwise firmly fixed to strip fastening material of the hook and loop type that would mate with corresponding strips of fastening material on the upper surface of the sponge. The arrangement between the intermediate backing plate and the sponge according to this embodiment would be essentially the same as the arrangement between the rigid flange and the sponge in the first o-f the preferred embodi-ments of my invention mentioned earlier. In each case, the . . , . , , . ,~

sponge is gripped firmly in place by the hook and loop type fastening material when the mop is in use, and the sponge may be readily detached from the rigid plate to which it normally adheres simply by detaching one set of the comple-mentary hook and loop type fastening material strips fromthe mating set on the facing backer plate or rigid flange, whichever is chosen.
While it is conventional to use a flat rigid flange or flat intermediate backer plate~ it is possible to use curved plates or flanges instead; the essential requirement is that the upper surface of the sponge con-form generally to the undersurface of the plat2 or flange to which it is supposed to adhere by means of the hook and ~5 loop type fastener strips.
Other variants will readily occur to those reading this patent specification.

Detailed Description of the Preferred Embodiment A conventional mop frame to which disposable15 sponge mop-heads are attached is illustrated in Figure 1.
The mop frame consists of mop handle 1 and mop-head sup-port plate 2. Mop-head support plate 2 has holes 3 through which the bolts or nipples which protrude from conventional replacement sponge mop-heads are inserted.
Figures 2 and 3 illustrate the top and bottom faces, respectively, of a securably detachable backing plate 4 for mounting on support plate 2. Backing plate 4 has slots 5 through which are threaded bolts 6 for mating engagement with corresponding holes 3 on support plate 2.
5trips of Velcro (TM) 7 are affixed longitudinally to backing plate 4. Backing plate 4 thus adapts a conven-tional mop frame ~or use with sponge 8 as illustrated in Figure 4.
As depicted in Figure 4, sponge 8 has strips of Velcro (TM~ 9 affixed longitudinally to its upper surface for mating engagement with corresponding Velcro ~TM) strips 7 on backing plate 4. Velcro (TM) strips 9 are affixed by adhesive such as #30 N.F. Green Contact Adhesive manufactured by 3M
Corporation, or by any similar adhesive which will bond to, , ~ .. . .

Velcro strips 7 are adhesively bonded to backing plate 4.
In operation, a conventional replacement sponge mop-head, that is, a sponge mop head having an integral backingplate irxeversibly attached to the sponge, is replaced on support plate 2 by backing plate 4. Bolts 6 are threaded through slots 5 and holes 3 on mop-head support plate 2. As shown in Figure 5, wing nuts 10 may be tightened onto bolts 6 to further secure backing plate 4 to support plate 2. Sponge 8 is then detachably secured to backiny plate 2 by mating Velcro (TM) strips 7 on the lower surface of backing plate 4 with corresponding Velcro (TM~ strips g on the top surface of sponge 8. Sponge 8 is thereby sufficiently secured to back-ing plate 4 so that sponge 8 may be used as a mop-head ~or mopping.
In an alternative embodiment, mop head support plate 2 acts as a ~lange, to the lower surfaca of which Velcro (TM) strips 7 are bonded directly. Sponge 8 may then be detachably secured to Velcro (TM~ 7 on support plate ~, without requiring the use of intermediary backing plate 4, by mating Velcro (TM) strips 7 on the lower surface of support plate 2 with corre-sponding Velcro (TM) strips 9 on the top surface of sponge 8.
Sponge 8 is thereby sufficiently secured to the mop frame so that sponge 8 may be used as a mop-head for mopping. Figure 6 illustrates a mop frame having Velcro (TM) 7 bonded to the lower surface of support plate 2. In thi.s embodiment support plate 2 is of sufficient width and length to provide the requisite area of Velcro (TM) 7 needed to sufficiently secure sponge 8 to the mop frame~
When spong2 8 becomes badly soiled and it is desired to wash sponge 8 in a washing machine or by hand, a gentle tension applied to one corner of sponge 8 separates sponge 8 from backing plate 4 by disengaging Velcro (TM) strip 7 from corresponding Velcro ~TM) strip 9.
