Abstract
A cleaning attachment for converting a cleaning implement, such as a broom, to a mop includes a flexible cover having end sections interconnected by a central section. Fastening structure secures the end sections together to create an enclosure for the broom head. Reusable mounting structure is provided on the exposed lower outer surface of the central section for engagement with a wipe.
Description




BACKGROUND OF THE INVENTION




For years now, brooms have been used for both interior and exterior floor cleaning procedures. Brooms come in all types and sizes, but the most common is the type that looks like an oversized paint brush (with corn bristles) and the long handle. In particular, the most widely used type broom today on interior floor surfaces is a plastic bristled broom having bristles cut on an angle to facilitate sufficient floor sweeping and has a long handle so the user can stand upright.




A disadvantage of brooms is that they can only sweep up dry soil of a rather large size and have no absorbative ability on dry or wet soils. Recently, new products have been introduced into the “handled goods” market. These products are essentially disposable dust mops that will absorb dust and pet hair on hard surface flooring. These new implements use disposable, dry, nonwoven cloths sized approximately 10″ by 12″. These dry wipes are attached to a hard, flat, rectangular plastic mop head with an elongated handle. The cloths are discarded when dirty and a new one is attached. A recent variation is a wet wipe version for mopping kitchen and bathroom floors.




If one wants to damp mop or wash the floor the most common thing to do is to purchase another cleaning implement such as a “string mop” or sponge mop to be used with detergent, water and a bucket. Mopping wood flooring requires additional and different cleaning agents.




SUMMARY OF THE INVENTION




An object of this invention is to provide a simple attachment that could be used with a broom or other cleaning implement to accommodate disposable wipes for use with virtually all hard surface flooring, dusting and mopping jobs.




A further object of this invention is to provide such a cleaning attachment which can be easily applied to the broom head covering the bristles and which can readily have either a wet or dry wipe detachably mounted to the attachment.




In accordance with this invention a cleaning attachment for converting a broom to a mop comprises a flexible cover having end sections interconnected by a central section. The cover would be placed around a broom head with the end sections fastened together to form an enclosure around the broom head. The central section would be located below the bottom of the broom head and includes reusable mounting structure on the outer surface of the cover at the central section to detachably mount a wipe to the outer surface below the broom head thereby converting the broom to a mop. The wipe would be detached after one or more uses so that a different wipe could replace the original wipe.




In a preferred embodiment of this invention the mounting structure structure on the outer surface of the central section is in the form of hook members of the known hook/loop VELCRO® construction. A preferred wipe is a needle punched material having loops that would be caught by the hook members on the cover. The wipes could be either wet wipes or dry wipes. The cover could be a flat sheet which when placed around the broom head, forms an open sided enclosure. The size of the flat bottom central section could be increased by folding portions of the end sections and then securing the folded portions to the central section. In a variation of the invention the cover is of a bag type that completely encloses the broom head. If desired, the cover could be impregnated with a cleaning composition.




The attachment could be used for cleaning implements other than the above described broom. For example, the attachment could be fastened to a mop, such as a sponge mop, so that the sponge mop (which ordinarily would be used wet) could be used as a dry mop for dusting purposes. The cleaning implement may also take other forms such as a large industrial/institutional push broom.

DETAILED DESCRIPTION





FIG. 1

shows a conventional broom


2


which can be converted to a mop in the practice of this invention. As shown in

FIG. 1

the broom


2


includes an elongated handle


4


and a broom head


6


. The broom head has bristles


8


such as corn bristles which may be cut at an angle.




Broom


1


would be used in a customary manner by, for example, sweeping floors. Under certain conditions, however, it would be desirable to convert the broom to a wet or dry mop. This is accomplished by mounting an attachment


10


around the broom head


6


so as to create an enclosure around the broom head. As shown in

FIG. 6

the attachment


10


is a cover in the form of a flat flexible sheet which includes a pair of end sections


12


,


14


connected to each other by a central section


16


. Attachment


10


is made of any suitable flexible material as later described. When the attachment is mounted around the broom head


6


the central section


16


of attachment


10


is located below the bottom of the bristles


8


of the broom head


6


and assumes the flat condition of the bottom of the bristles


8


. The outer surface of the central section includes reusable mounting structure


18


so that a wipe


20


could be attached to and located outwardly of the central section


16


. The wipe


20


in essence forms a mop head which could be used for virtually all hard surface flooring, dusting and mopping jobs. Because the wipe


20


is detachably mounted to the central section


16


and since the same mounting structure


18


on the central section could be reused, either wet or dry wipes can be selectively applied to the attachment


10


. Since the attachment


10


is flexible it does not hamper the flexibility of the broom itself.




As shown in

FIG. 6

end section


14


of attachment


10


is notched or bifurcated and terminates in a pair of outwardly extending flaps


22


,


22


. The inner surface of flaps


22


,


22


is provided with fastening structure


24


which could be in the form of VELCRO® hooks or loops. End section


12


includes on its outer surface complementary hooks or loops


26


to provide complementary fastening structure which would engage and be locked to fastening structure


24


. Complementary fastening structure


26


could be two aligned strips corresponding to the location of fastening structure


24


on flaps


22


,


22


or could be a single strip across end section


12


.




As shown in

FIG. 2

attachment


10


would be wrapped around the broom head


6


. End section


12


would be folded along a side of broom head


6


. The flaps


22


,


22


would then be folded over the top of broom head


6


so that its fastening structure


24


is exposed would be located at fastening structure


26


. The fastening structure


26


on end section


12


would engage fastening structure


24


on flaps


22


,


22


to create an open sided enclosure as shown in FIG.


3


. The open sided enclosure would have the central section


16


below the bottom of the bristles


8


. Central section


16


would have a flat shape with its reusable mounting structure


18


exposed on the outer surface of central section


16


.




Any suitable type of reusable mounting structure


18


could be used. In a preferred practice of the invention the mounting structure


18


is the hook portions of velcro material.

FIG. 4

thus shows a VELCRO® hook strip


18


to be located on the exposed outer surface of central section


16


. The hook structure is particularly suitable to have secure attachment of a wipe


20


where the wipe is made of a known needle punched material. A needle punched material is a known nonwoven fabric which is a dense machine entangled material having a surface of fiber loops and twists. Thus, the hooks of mounting structure


18


would engage the loops of wipe


20


. Alternatively, other types of materials as later described can be used for wipe


20


with other types of fastening structures. For example, the wipe material (of a form other than needle punched) may be provided with one or more strips of hook or loop formations from a VELCRO® material which would be engaged with the complementary hooks or loops as the fastening structure


18


on bottom section


16


.




Needle punched nonwoven fabric is particularly preferred for wipe


20


because it results in a “hairy” surface in which the hooks of mounting structure


18


can entangle and hold onto the wipe


20


. This facilitates moving the broom in a sweeping manner. Since, however, the wipe


20


is on the bottom the broom actually functions as a mop. Moreover, dry needle punched fabric can hold onto dirt and soil (pet hair, etc.) On the other hand pre-moistened needle punched fabric can hold onto cleaning solutions and at the same time release the solution as it is moved over the flooring surface. An integral part of the wipe is the composition of the fibers, i.e. polyester, rayon, cotton, etc. If desired the wipes


20


could be formulated for dry wiping to attract dust and dirt, pre-moistened compositions for kitchen floors, bathroom floors (disinfecting and deodorization) wood floor compositions, mop and shine wipes for waxed floors, “sticky surface” wipes for carpeting to reduce vacuuming, etc.




The attachment


10


and wipes


20


in wet and dry form could be pre-packaged in kit form using any suitable packaging techniques.




In use the consumer would simply attach the attachment


10


to the broom, pull out a suitable wipe from a package and stick the wipe on the bottom or central section of the attachment locating the wipe in the hook area on the bottom. The consumer would then use the broom/mop in a conventional manner. As the broom goes over the floor the attachment holds onto the wipe in an extremely secure manner. The consumer can press on the broom to get at corners, under overhangs, right up close to baseboards, next to appliances, as well as broad areas of open flooring. The bristles


8


of the broom flex and bend to accommodate the flooring surface. Thus, the wipe


20


can be pinpointed or can be used broadly. The resultant converted mop would actually be better than a conventional dirty sponge or a string mop for wet mopping. The invention would avoid the need for dripping buckets of water, etc. For dry mopping the invention would be superior to the known variations previously described where dry nonwoven cloths are attached to a hard, flat, rectangular, plastic mop head because the invention is more flexible and convenient to use. Moreover, the attachment and wipes would be less expensive and take up less shelf space in stores. This would lend itself to higher profit margins.




Preferably, the wipe


20


is made of the same size (i.e. length and width) as the central section


16


. If desired, the wipe


20


could be made slightly smaller in either length and/or width or the wipe could be larger in either length and/or width than the central section


16


.




If desired, further reusable mounting structure could be located on the outer surface of one or both end sections


12


,


14


and an oversized wipe


20


could be used which would then be folded against one or both end sections


12


and/or


14


for additional engagement of the wipes with the attachment


10


.




If desired, fold lines


28


,


28


could be provided at the edges of central section


16


to assure, that the central section has a proper width corresponding to the width of the bottom of the broom head bristles


8


. Similarly, fold lines


30


,


30


may be provided to facilitate the folding of the flaps.




It is also to be understood that the end sections


12


and


14


may be secured together by having either the fastening structure


24


of the end flaps


22


,


22


on the outer surface to engage fastening structure


26


on the inner surface of end section


12


where the flaps would be inside of end section


12


or conversely by having the mounting structure


24


on the inner surface of flaps


22


,


22


to engage the fastening structure


26


on the outer surface of end section


12


, as illustrated in FIG.


3


. Thus, either the flaps would be first folded over the broom head and then the end section


12


would be folded outermost against the flaps or the end section


12


would be first folded around the broom head and the flaps would then extend over and be folded against the end section


12


.




It is also to be understood that the attachment


10


may include as the fastening structure and the reusable mounting structure fastening elements such as velcro strips located at one or more areas of the attachment. Thus, for example, the central section


16


may have a single VELCRO® strip


18


or may have a plurality of spaced or juxtaposed strips. Similarly, the flaps


22


may have one or more sets of strips which could be either over a wide area or over narrow areas of the flaps and correspondingly the end section


12


could have one or more sets of strips or other fasteners.




When the broom


2


is converted to a mop by attaching a wipe


20


the broom can later be reconverted back to a broom by removing the wipe


20


and attachment


10


. Similarly, when the broom is converted to a mop a wipe can be removed and disposed of after a single or multiple uses. The wipe


20


can then be replaced by the same or different type of wipe. Thus a dry wipe could be removed and a wet wipe mounted in its place, or vice versa, or a wet or dry wipe could be removed and replaced by the same type of wet or dry wipe, particularly where the removal is because the prior wipe has become too dirty.





FIGS. 7-9

illustrate a modified attachment


10


A. As shown therein attachment


10


A would also include end sections


12


,


14


with flaps


22


,


22


extending from end section


14


as previously described. Similarly, fastening structure


24


,


24


would be provided on flaps


22


,


22


for engagement with fastening structure


26


on end section


12


. Attachment


10


A differs from attachment


10


in that the bottom section


16


A is made of larger size. This is accomplished by providing folds


32


,


32


on end sections


12


,


14


which are secured such as by sewing or heat sealing to the central section


16


A thereby creating extended areas


34


on top of central section


16


A. This results in a larger size central section and permits the use of larger size wipes


20


to be detachably mounted to central section


16


A. As shown in

FIG. 9

the reusable mounting structure


36


could be located at the bottom of central section


16


A at a location below the extended areas


34


.





FIGS. 10-11

illustrate yet another form of attachment


10


B which is generally in the form of a bag having side walls


38


,


40


and end walls


42


,


42


with an open top. The bottom wall


44


would correspond to the previously described central section


16


. Bottom wall


44


would include reusable mounting structure


46


which could be in the form of a pair of VELCRO® hook strips for engagement with wipe


20


. The bag could be loose fitting or dimensioned to be custom fit for broom head


6


. In use the bag would be slid over the broom head


6


to completely cover the bristles


8


and broom head


6


. The open end of the bag would then be secured to the broom head in any suitable manner such as by the use of a twist tie


48


which closes the bag around the handle


4


. Attachment


108


would be particularly useful with large size brooms. The attachment


10


B thus forms an enclosure which completely encloses the broom head. Although

FIG. 11

illustrates the use of twist ties


48


as the fastening structure, other types of fastening members could be used including tie members integrally formed on the attachment


10




b.






The disposable bag or attachment


10


B can be made entirely of materials consisting of nonwoven, woven cloth, combinations, etc. and various plastic material, such as polyethylene, polypropylene, PET, etc. designed specifically for dusting floors, walls, etc. The use of the converted broom would provide the ability to reach high corners of a room to remove cobwebs. A user could dust, clean, remove the spiderwebs, etc. and then dispose of the attachment and removed material without much fuss and mess. In addition, the closed bag could contain water activated cleaning compositions that could be activated by moistening under tap water for damp brooming or damp mopping. If desired the central bottom section


16


or


16


A of the previously described attachments could also be impregnated with activated cleaning compositions and then activated by moisture from tap water.




The attachment


10


B is designed so that it has a flat, yet flexible bottom to match larger size disposable cleaning cloths in either wet or dry form. The flat bottom


44


allows the use of a larger surface area of hooks


46


,


46


to be applied for holding onto the disposable dusting or wet mopping cloths or wipes


20


.




The invention has been described with regard to

FIGS. 1-11

where the cleaning implement is a conventional broom having a broom head with bristles. The invention may be practiced with other types of cleaning implements.

FIGS. 12-13

illustrate a cleaning implement in the form of a sponge mop


2


A having an elongated handle


4


, a head


6


A and a sponge


8


A as the cleaning portion of the sponge mop. The sponge mop


2


A may be provided with any of the aforenoted types of attachments so that, for example, the sponge mop, which is traditionally used wet, could be converted into a dry mop for dusting floors, etc.





FIGS. 12-13

illustrate an attachment


10


C similar to attachment


10


for converting the implement or mop to a dry mop. Like reference numerals for attachment


10


C are used for like parts in attachment


10


. The main differences between attachment


10


and attachment


10


C of

FIGS. 12-13

is that the end section


12


is also provided with a central notch and outwardly extending flaps


22


A,


22


A. Thus, both sets of flaps


22


,


22


and


22


A,


22


A would be folded over the head


6


A of mop


2


A with the outermost flaps being the flaps having the fastening structure on its inner surface. If desired, however, an attachment without two sets of flaps could also be used.




As noted, any of the previously described type of attachment could be mounted on mop


2


A. Thus,

FIG. 14

illustrates a bag type attachment


10


D similar to attachment


10


B which would be mounted over the cleaning end of mop


2


A.




It is to be understood, as described with respect to attachment


10


B, that the bag type attachment is preferably a loose fitting bag tied at its upper end to the handle of the cleaning implement. The invention may be practiced, however, where the bag type attachment is custom fit by being suitable dimensioned to correspond to the dimensions of the cleaning head of the cleaning implement whether the cleaning implement be a broom, mop or other type of cleaning implement.




Although not illustrated, the sponge mop


2


A could also be provided with an attachment similar to attachment


10


A where the bottom central section is of extended dimension.





FIG. 15

illustrates a further type of cleaning implement, namely, a large industrial/institutional broom


2


C having an elongated handle


4


with a cleaning head


6


and cleaning bristles


8


.




The attachment


10


E in

FIG. 15

is a combination of the attachments


10


A and


10


C. Thus, as with the attachment


10


C attachment


10


E includes a set of flaps


22


A,


22


A which fold over flaps


22


,


22


on top of broom head


6


. Attachment


10


E also includes folded portions


34


A,


34


A which extend or increase the overall size of the bottom or central portion of attachment


10


E. A band or strip of mounting elements


36


A such as hook portions may be attached to the bottom side of extended folded portions


34


A for securement to dry or wet disposable or limited use wipes


20


.





FIG. 16

illustrates an attachment


10


F which may be of a bag type having mounting structure on its bottom surface for attachment to wipe


20


. The bag type attachment


10


F would be made significantly longer than cleaning head


6


with its bristles


8


so that attachment


10


F could extend a sufficient distance up handle


4


to be closed in any suitable manner, such as by twist ties.




Where the invention is used by securing the attachment to a mop it is preferable that the mop is a sponge mop as previously described. It is to be understood, however, that the invention could also be used with other forms of mops, such as a dry mop, particularly where it is desired to utilize the attachment for mounting a wet wipe so that the mop could be used for wet mopping by means of the attachment as well as dry mopping without the attachment. Similarly, where the mop is a wet or is a dry mop, the wipe could be of the same type (i.e., wet or dry) or of the opposite type as the mop itself. Thus, a sponge mop which would ordinarily be used wet could have a wet wipe or a dry wipe mounted to the sponge mop through use of the attachment.




The invention could be practiced with various types of disposable or limited use cleaning cloths which can be dry or wet for various cleaning jobs, such as dry mopping, waxing, damp mopping, scrubbing, etc.




It is to be understood that although the invention has been described by reference to preferred materials, such as velcro type fastening or mounting structure and needle punched wipes, other types of fasteners and materials can be used. For example, wipes


20


could be made nonwoven or woven in single or multiple ply form made from such materials as polyester, rayon, cotton, polypropylene, nylon, fiberglass, rubber, cellulose, polyurethane, polyethylene and PET. The attachment or cover material itself could be made of any suitable flexible material such as woven fabric, nonwoven fabric, plastic, paper, cardboard, wood, leather, metal or combinations thereof. The fastening structure and reusable structure could be hooks and loops as previously described, snaps, buttons, magnets, clasps, etc. Where the invention is practiced by incorporating a cleaning material into the wipe and/or attachment, such cleaning compositions could be disinfectants, surfactants, wood floor cleaners, wax etc. which are either water based, non-aqueous or combinations thereof.




It is also to be understood that various features described with regard to a particular embodiment, may be used with other embodiments where desired and appropriate.
