By the present invention I have provided a mopping or cleaning device in which a plurality of superposed separable cleaning elements, such as sheets of paper or cloth, are releasably carried by a supporting head member which is so formed and constructed that it is entirely flexible. Bv reason of this flexible construction of the head member it is possible to use the device in mapping or cleaning any .irregular or uneven surfaces or any remote areas, corners or other parts which taken on ,the line of athird embodimay not be reached when the usual type 0i mop is employed. By reason of the provision 4of the superposed, separable cleaning sheets it is possible, after placing a plurality of such sheetson` thel mop head, to successively use these in the cleaning l 5 operation, it being merely necessaryto remove the outermost sheet when this becomes soiled or unfit for further cleaning, thereby Vexposing a f fresh `and unsoiled sheet.
portion I,`- the thickness Aof which is preferably ,small as compared to its other` dimensions, there- `by forming a flat slab-likemember having spaced `20 longitudinal edges ZY-and 3, thiswhead member Y ,constitutinga supportlfor the cleaning' elements wh-ichrwill be. described. hereinafter. vI ntegrally `formed-with this mopping. or cleaning head I'and extendingfrom the` upper longitudinal edge4 2 .25 thereof, and being generally formedintheplane ofthe head,is anextensionor neck lon theouter end of which is preferably 'formed a handle? .receivingv ferrule 5. If desired, a handle maybe integrally formed with the neck II or with the head ,30 member I in placeof the ferrulei, su'chhandle ,being` preferably so formed that it may bei grasped bythe hand.,` According to my invention, I form this entire mopping head, including the flat portion,V I, the Y`neck 4 and thehandleor handle-,- g35 receiving ferrule 5, of some flexiblepreferably resilient material such` as softrubber orls'ponge rubber. While Vit may not` be necessary in `all cases to form the ferrule'5 of such material, it is a,.featurefofmyinvention that the entire sup- 4Q porting head is so formed.` I have found that greatly improvedresults are secured by also forming the neck portion 4,`which connects, the handle receiving ferrule. to the head, of flexible orresilient material, this providing additional and greater i5 flexibility to the entire mapping device. Means are provided by the invention for attaching to the head member the cleaning elements which are contemplated by the present invention. Such means are formed in the upper 50 longitudinal edge 2 of the head member I and extend from each side of the neck portion 4 toward the opposite ends of the cleaning head, and in the preferred form of the invention, comprise slots or apertures 6, 'I which extend into the material 55 of the head from the longitudinal edge 2 toward the longitudinal edge 3 for any desired distance and which cooperate with the cleaning elements in a manner to be fully described hereinafter. These slots or apertures are preferably formed in such a way that the entrance thereto, which is preferably, but not necessarily, formed. in the exterior surface oi the longitudinal edge 2, is made quite narrow and restricted, while the interior portion of the aperture is enlarged considerably. This construction may be achieved by forming inwardly-facing elongated beads or ridges, such as 8, 9, on the inner surfaces of the portions of the head member which are adjacent the edge 2 and which deiine the apertures or slots. It will be seen that by reason of the fact K that the entire cleaning head is formed of resilient or flexible material, the walls of the aperture 6 may be moved with respect to each other and when held apart, as by any material being disposed within the aperture 6, these walls will tend to return to their normal position adjacent each other and will therefore exert a yielding pressure on any material within the apertures 6.
It will be apparent that the head I may be formed in a single piece by a molding operation, or may be formed by folding a piece of sponge or other rubber and cementing the abutting faces together, leaving the slot or aperture as an uncemented edge portion. This head member may also be formed by cementing together two pieces of sponge or other rubber, again leaving one edge portion un-attached in order to provide the aperture or slot. All of these, and other, methods of forming the head member are included within the scope of my invention.
Cleaning means are provided by the invention and are adapted to be mounted on th-e head member hereinbefore described. According to the present invention I propose to entirely cover the head member 6 by wrapping around it a pluralityof superposed, separable cleaning elements such as sheets of paper or cloth, any number of the elements of which may at any time be removed as desired in order to expose a fresh cleaning surface. These sheets of cleaning material are illustrated at Ill in the drawings and it will be seen that these may be rectangular sheets of cleaning material which are wrapped relatively tightly about the head I and the adjacent free edges of which are brought together and disposed within the apertures or slots 6 which extend along the upper longitudinal edge of the head I. When the edges of the sheets of cleaning material are so disposed within the slot or slots 6 it will be seen that these sheets will be held securely on the head I and that the portions of the head which define the slots 6 will exert yielding pressure on the edge portions of the sheets of cleaning material in order to hold these edge portions within the apertures, thereby maintaining the entire group of sheets in proper position on the head member. It will also be seen that as the outermost sheet of material becomes soiled and unfit for further cleaning purposes it may be stripped off without disturbing in any way the remaining sheets of cleaning material, thereby exposing other sheets for cleaning purposes.
v By reason of the entirely flexible construction of the head I and the connection of this head to the handle B by a flexible neck 4, it will be apparent that the entire cleaning head with the cleaning sheets mounted thereon may be used in any corner or uneven area or surface which might not ordinarily be reached by a mopping device of the usual type. It will be apparent that in order to achieve this result the sheets of cleaning material ID must be of flexible nature.
In Figs. 3, 4 and 5 of the drawing I have illustrated a second embodiment of my invention and it will be seen that this form is generally similar in nature and construction to that illustrated in Figs. l and 2 and is somewhat preferred over the form illustrated in Fig. 1 by reason of being cheaper in construction and being so constructed as to permit access to areas which might not be reached by the device of Fig. l. In this embodiment of my invention the mop head, which is generally designated at I5, is formed of generally triangular shape. One side of the triangular head, which is preferably the longer side I6, may be designated as the cleaning or lower edge of the mop. Extending from the apex opposite this lower edge of the mop is a neck portion I'I to the outer end of which is attached a handle or handle-receiving ferrule I8. The two sides of the triangular head which extend from the neck I? to the ends of the cleaning edge I6 are provided with slots or apertures I9, 26 which are preferably formed in the same manner as the slots or apertures I5 of the device of Fig. 1. This entire head device, preferably including the neck portion II, is formed of flexible or resilient material such as soft rubber or sponge rubber, for the purposes set forth hereinbefore. An assembly of superposed, separable sheets of cleaning material of the character hereinbefore described are adapted to be wrapped about the head I5 and the free edge portions of these sheets are received within the slots or apertures I9, 20, whereby the superposed cleaning sheets will be held in position about the mopping head.
It will be apparent that the slots or apertures formed in the head members disclosed in Figs. 1 and 3 need not extend entirely to the ends of the head members although, if desired, they may not only extend to the ends of the head but may also extend along the end edges of the head. It is to be understood that the fact that I have shown these apertures or slots as extending to the ends of the head is not to be considered as limiting the invention in any way, and these slots may be made of any desired extent. As illustrated in Fig. 5, it is preferred that the slots formed in the triangular head illustrated in Fig. 3 be extended to intersect the lower or cleaning edge I6 of the head.
A still further form of my invention is illustrated in Figs. 6 and 7 of the drawing. Referring iirst to Fig. 6 it will be seen that this embodiment of my invention comprises a handle portion 30 and a mopping or cleaning portion 3|, this mopping or cleaning portion being releasably attached to the handle 30 by some means such as the spring clamp 32 which is carried by the handle. As will be seen clearly from the disclosure of Figs. 6 and '7 I propose to form the cleaning element 3| by superposing a plurality of cleaning sheets 33, such as sheets of paper or cloth, ony a similarly shaped sheet 34 which may be formed of sponge rubber, soft rubber or other flexible material and which provides a backing or support for the sheets of cleaning material 33. This assembly, after being made up, as illustrated in Fig. '7, is folded alonga medial line and the adjacent free edges of the folded assembly are inserted between the handle 36 and the movable jaw of the clamp 32 which is mounted on the handle, thereby maintaining the cleaning assembly in folded condition and attaching it to the handle. In the preferred form of this embodiment of my invention, as illustrated, the rectangular sheets of paper are superimposed upon an octagonal backing sheet. When this assembly is folded, the corners of the paper sheets will overlap the backing sheet and these corners may be folded between adjacent edges of the backing sheet to thereby provide a more secure assembly. This folded assembly provides a fiexible cleaning head from which successive sheets of cleaning material may be stripped as they become soiled.
While I have illustrated and described certain embodiments of my invention it will be apparent to those skilled in the art that the invention is not limited in any way by the constructional features disclosed in the drawing and that the scope of my invention is not restricted in any Way but by the appended claims.
