No. 30,145, filed Apr. 20, 1970, now abandoned.

BACKGROUND OF TI-IE INVENTION The invention relates to the field of cleaning implements, such as mops, and has particular relation to the use of mop elements formed of nylon net or any suitable open-ended material from the new synthetics such as those made of polyvinyls, polyesters, or polyethylene, or any other suitable synthetic resins commonly known as plastics. These hydrophobic fibers are desirable for use as mops for the reason that they are non-porous, non-absorbent and not hanned or affected by moisture or cleaning agents, and they provide an effective cleaning action.

Single elements of such material as nylon net are now in use as cleaning elements, and are particularly effective for cleaning pots and pans because of their efficient scrubbing action, es ecially in the presence of cleaning compounds. These single cleaning elements are relatively small, do not cover substantial surfaces and are not adapted for use with handles whereby the person cleaning can scrub bathtubs, toilet bowls and the like without bending or stooping. Moreover, efforts to secure such elements to handles have been impractical since the lower ends of the handles can come into contact with and scratch surfaces being cleaned, this being particularly true of enameled surfaces.

SUMMARY OF THE INVENTION The present device is made up of two or more nylon net elements in strip form, of appreciable width, for example, four inches. These strips are long and while the number of strips employed is not limited, it is preferred that five strips be employed for a reason which will become apparent. Each of these strips is relatively long, for example, 72 inches and each strip is gathered longitudinally from end to end centrally of its width, whereupon the strip is rolled. Under such conditions, the center of the roll representing the gathered longitudinal center line portion will be small, and the element will expand into substantially conical form on opposite sides of such gathered center. In gathering the strips, the gathered line may be fixed in any suitable manner, for example by stitching, but it is preferred that pressure and heat be employed to fuse the material.

After such gathered strip has been rolled, the contracted central portion is preferably reduced in size by applying circumferential pressure and heat to fuse the turns of the wound strip to anchor it into shape. One of the elements thus formed is bent at its center over the cross member of a U-shaped holder, the two ends being bent downwardly and diverge in all horizontal directions because of their normal conical forma tion as described above. Just below the transverse element of the U-shaped member, such cleaning element is then either lock stitched or fused under pressure, thus preventing the U- shaped member from ever coming into contact with the surface being cleaned.

The remaining gathered, rolled and fused elements, which may be four in number, then have their central portions arranged in circumferentially spaced relation around a plug, socket or handle to the bottom end of which the U-shaped member is connected. A binding flexible element is then tied around the centers of such cleaning elements to fix them to the socket or the like, which may be broadly termed as a holder. This holder may be circumferentially grooved near its lower end so that the binding element tied therearound will enter such groove between the gathered central portions of the cleaning elements to fix them against sliding movement along the holder. The flexible tying element is preferably nylon cord, although any metallic wire may be employed, preferably of non-ferrous material to prevent its rusting or corroding. Each of the elements tied around the holder will flare out vertically from the gathered center as well as circumferentially, and these elements blend with each other and with the bottom element to appear as a single large fluffy cleaning element.

The cleaning elements may be of any desired color to enhance the attractiveness of the article, and its appearance may be improved by tying a colored bow of ribbon around the holder above the cleaning unit. The holder also may be provided with a loop by which the implement may be hung upon a hook. With the structure described, the holder may be provided with a long handle whereby such units as a bathtub or toilet bowl can be readily and thoroughly cleaned without the users having to bend, stoop or kneel. The device provides not only an effective cleaning unit, but it is impossible for any hard elements of this structure, such as the U-shaped member or holder to come into contact with the surface being cleaned, thus preventing the scratching of the surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Refen'ing to FIG. 1, the numeral 10 designates a strip of material used in making the mop. This strip is preferably formed of nylon net but may be made of any of the materials previously described. Two or more of the strips will be used in the making of the mop, and it is preferred that a number of the strips, for example five, employed for convenience in handling as will become apparent. The strip shown in FIG. 1 may be of any width and in practice it has been found that a strip 4 inches wide is desirable. This strip, by suitable mechanical means, is gathered along the longitudinal center line indicated by the numeral 12 to substantially reduce the length of the strip. After the strip has been gathered in this manner, the reduced central length is fixed, for example by stitching the strip, but preferably by fusing the material of the net. Afier being thus fixed as to length, the strip is wound from end to end and will then appear as shown in FIG. 2, the gathered central portion 14 being of relatively small diameter and with the material of the cleaning element diverging upwardly and downwardly, as at 16 in substantially conical form. The center 14 is then subjected to a circumferential contracting force with applied heat to further reduce the center as at 18, the material being fused by the heat so that it will retain the shape shown in FIG. 3.

Assuming that the element shown in FIGS. 2 and 3 will form the bottom element of the mop, this element indicated by the numeral 20 in FIG. 4 will be bent at its center 18 to extend across the transverse element 22 of a U-shaped member 24 having upstanding parallel ends 26. After the element 20 is thus bent into position, it is stitched below the transverse element 22 as at 28 or heat and pressure are applied to the material along the line 28 to fuse the element and thus fix it to the U-shaped member. Because of the formation of the rolled element in FIGS. 2 and 3, it will be apparent that the element will diverge downwardly in all horizontal directions as shown in FIGS. 4 and 5.

The U-shaped member 24 is then anchored to a suitable holder. In FIG. this holder is indicated by the numeral 30 and may be formed of thennoplastic with the ends 26 embedded in the plastic while soft and the setting of the plastic will fix the U-shaped member in position. The member 30 forms the holder for the entire mop structure and may be of sufficient length so that the upper end may be grasped as a handle where the surface to be cleaned is readily accessible without bending or stooping. Near its lower end the holder 30 is preferably provided with a circumferential groove 32 for a purpose to be described.

The remainder of the mop is then formed of one or more and preferably four of the strips for convenience in handling. Assuming that four such elements are employed, each will be formed as shown in FIGS. 2 and 3 to form elements 34 (FIG. 8), central portions 18 of which will be arranged against the holder 30 around the groove 32. In FIG. 8 a definite line of demarcation has been shown between the elements 34 for the purpose of clarifying the arrangement of the surrounding mop elements. It will become apparent, however, that due to the irregularity of the material and its gathering, no physical line of division will appear between the elements 34 and they will appear as a solid surrounding net structure. After being so placed in position, the elements 34 are fixed to the holder by a binding flexible element 36. This element is preferably nylon cord but any non-ferrous wire may be employed. Because of the reduced size of the center 18 (FIG. 3) of each element, the flexible element 36 will engage in the groove 32 between the element centers 18. Thus the surrounding elements will be fixed to the holder, and they will blend with each other and with the bottom element 20 to appear as one mop unit, and the net material employed will preferably be of an attractive color. Above the mop unit as a whole, a colored ribbon 38 may be tied around the holder 30 and may be provided with a bow knot 40, thus enhancing the attractiveness of the device.

In FIG. 6 a holder 42 is shown which may be identical with the holder 30 except that it is provided with a threaded axial opening 44 to receive the threaded lower end of a handle 46 which may be of any desired length, for example 35 inches, so that such units as bathtubs and toilet bowls may be effectively cleaned without requiring the operator to bend, stoop or kneel. The threaded connection of the handle in FIG. 6 is merely illustrative, and it will be apparent that any means may be employed for connecting the holder and the handle. It also will be apparent that the device may be provided with handles of different lengths for convenience in different uses of the mop.

In FIG. 7 a different type of holder 48 is employed which need not be in the form of a thermoplastic element as in FIG. 5. The holder 48, for example, may be fonned of wood grooved at opposite sides as at 50 to receive the upstanding arms 52 of a U-shaped member 54, the upper ends 56 of which may be turned inwardly to snap into recesses 58 formed in the holder 48.

The mop as described is highly effective in use for cleaning open accessible surfaces. Some surfaces, for example in toilet bowls, are not so accessible, in which case the form of the device shown in FIGS. 10 to 15, inclusive, is preferably used. In this case a plurality of superimposed strips 60 are used and these strips are gathered and then preferably fused along spaced lines 62 (FIG. 10) to form a tunnel 64 between such lines through which may be inserted a relatively stiff wire 66 (FIG. 1 1). When so gathered, each pair of superimposed strips will be shaped as generally shown in FIG. 12 to comprise one element of an auxiliary mop indicated as a whole by the numeral 68. The wire 66 will be relatively long and it is preferred that five of the units 68 be threaded on the wire 66. After being so threaded thereon, the wire will be bent into U-shape as shown in FIG. 13. If five units 68 are employed, adjacent units will terminate as indicated by the dotted lines 70 although because of the nature of the material, these lines will not be visible. The ends of the wire 66 project beyond the uppermost units 68 and these projecting ends are then bent together and twisted as at 72, whereupon these ends are inserted into a holder such as the holder 30 together with the upwardly extending ends 26 of the U-shaped member 24. The auxiliary mop unit formed by the elements 68 will then project downwardly and outwardly as shown in FIG. 15 to be inserted around the upper portion of the trap of a toilet bowl, which is ordinarily inaccessible.

The main mop is illustrated in FIG. 8, for example, will appear generally in practice as shown in FIG. 16 and the upper end of the holder may be provided with a loop 74 by which the mop may be hung on a suitable hook. As stated, the handle 46 may be of any desired length and at least one such handle of approximately 35 inches in length should be provided to render practicable the use of the mop without the operators having to stoop, bend or kneel for cleaning low surfaces such as bathtubs, toilet bowls or floors.

The material used in making the body of the mop, while highly flexible, is relatively hard-surfaced and provides an effective scrubbing unit. Thus the present device provides a relatively large mop for rapidly covering large surfaces and may be freely and vigorously used on surfaces which are capable of being scratched, such as enamel surfaces. The placing of the lower mop element 20 prevents the lower end of the holder or U-shaped member from coming into scraping contact with the surface being cleaned, thus protecting such surface from damage while subjecting it to an efficient cleaning action. By means forming no part of the present invention, the gathering of the net strips may very quickly and efficiently carried out and the assembling of the elements is quick and simple, thus presenting a highly efi'icient cleaning implement which may be manufactured at a very reasonable cost. The use of the auxiliary mop element shown in FIG. 15 permits inaccessible surfaces to be reached and the substantial gathering of the relatively stifi materials prevents any portion of the wire 66 from coming into contact with the surface being cleaned.

Specific reference has been made to the use of the materials named above in the making of the mop elements, and particularly nylon net, because of the highly desirable characteristics of this material. As stated above, it is relatively stiff to provide an effective scrubbing action and the material is hydrophobic. As a result, the material is unafi'ected by detergents and other scrubbing compounds which readily rinse from the mop. whereupon a shaking of the mop will dislodge substantially all water therefrom. The invention, however, is not limited to the use of any particular material in the making of the mop elements.
