Jan. 3, 1967 T. B. BELSKY ETAL HOLDER FOR MOP PADS Filed June 19, 1964 .ITIHITIHT Erz.
BY 7W #Ku ATTORNEYS United States Patent O 3,295,155 HLDER FOR MOP PADS Theodore B. llelslty, South Hadley, and Gloria B. Klart'eld, Holyoke, Mass., assignors to Ready, Inc., Holyolie, Mass., a corporation of Massachusetts Filed .lune 19, 1964, Ser. No. 376,504 2 Claims. (Cl. 15-147) This invention relates to a holder for mop pads and more particularly for pads constructed of loose cotton or textile materials as cotton batting for example, and for pads of resilient cellular construction such as soft `sponge rubber.
An object of the invention is to provide a holder which may be quickly applied to mop pads of the above type by simple pressure as with the users foot and without the need for movable parts requiring manual operation for attachment. A related object is to provide a holder from which such pads may be separated with equal ease for cleaning and re-use with the holder.
Other specic objects and advantages will be apparent from the following disclosure of an embodiment of the invention as shown by the attached drawings, in which,
FIG. 1 is an elevational view of a front or rear side of the holder;
FIG. 2 is a similar view showing the mounting of the pad on the holder by foot pressure;
FIG. 3 is an elevational view on an enlarged scale, of one end of the holder showing the needle-like prong gripping means before applying foot pressure to attach a pad;
FIG. 4 is a sectional view on line 4-4 of FIG. 2 showing the prongs inserted under pressure into the body of the pad material;
FIG. 5 is an end view similar to FIG. 3 with the pad in section to show the prongs embedded in the upper portion thereof; and
FIG. 6 is a bottom view of the holder.
The mop holder shown by the drawings is designed for use with a pad for dry or wet pad usage and as a general household utility mop as for oor, wall, or ceiling use. The holder, as shown, may be of an elongated rectangular shape as the flat base member, generally designated by numeral 2, which is here formed by a thi-n board 4 of stiff wood or composition board material with a U-shaped ruber buffer 6 wrapped around the edges of the piece 4 (see FIG. 4). The base and buffer may if desired be integrally formed as a single unit of stiff plastic, rubber, or the like.
At a central location on the upper surface of the base is fixed, as by screws 9 (see FIG. 5), a handle mounting fixture generally designated by numeral 8. On the fixture 8 are a pair of spaced straps 10 having axially aligned openings in which are pivoted the ends of a round wire handle swivel hanger 12. The wire is angularly twisted as shown so that the center is crosswise of the ends. On the center section is pivoted the rolled end 14 of a handle socket 16 in which the handle 18 is turned. This is a conventional type of handle swivel mounting for manipulating the mop in conventional fashion.
As shown by FIGS. l, 2 and 6 the undersurface of the base is preferably divided into a plurality of spaced sections 20 containing wire prong elements to be later described in detail, and intermediate sections 22 consisting of easily compressed material such as soft sponge rubber, cellulose or lplastic foam or the like. Sections 22 are alternately spaced between sections 20 along the length of the base within the boundary defined by buffer strip 6 (FIG. 6). In normal `condition the sponge or foam sections 22 provide a surface below the level of the tip ends of the wire prongs of sections 20. When the holder alone is resting on a floor, sections 22 maintain the wire prong sections 20 elevated above the surface of the floor. This Patented Jan. 3, i967 protects the floor from being scarred or the wires from unnecessary wear.
In FIG. 2 the attachment of mop pad to the holder by foot pressure is shown. The pad 24 is simply rested on a floor surface, the holder base being placed over the upper surface and pressure applied on top of the holder. As illustrated the user may simply stand with a foot on each half of the base or the foot may be pressed first on top of one side and then on top of the other. In either event foot pressure is sufficient to compress sections 22 of the soft sponge or cellulose material so that the prong of sections 20 can pentrate the upper surface of a pad and releasably grip the pad for use.
The mop pad 24 shown by FIGS. 2-5 is preferably of a construction similar to that disclosed in Patent No. 2,853,730 dated September 30, 1958, consisting of a batting material having a backing of thin sheet material 25, as crinoline, secured to the top face of the batting to hold the loose carded fibres of the batting material together. Such a pad is of the disposable type and is highly useful particularly for dry mopping purposes. It is to be noted that a soft sponge rubber or plastic foam pad of the same or similar cellular construction as sections 22 may also be used as a wet pad, the prongs lof sections 20 penetrating the material of 1a foam pad in a fashion similar to that now to be described in connection with the dry pad 24.
In FIG. 3 the pad 24 is shown resting on a oor surface and the holder placed on top ready for application of foot pressure. In this position the resilient sections 22 hold the wire prong sections slightly above the pad surface. The individual wire prongs 26 extending from a backing 28, which is secured to the undersurface of the base, are in a free hanging condition. The prongs have sharply angle tip end portions with the inner portions being angled slightly from the vertical. In each section 20 the wires are set in closely spaced rows (see also FIG. 6) and the wires in one half section as at 21 are angled in an opposite direction to those in the other half as at 23.
In FIG. 4 with the base member being under full foot pressure, the wires of the two half sections are shown as flexed and being deflected in opposite directions and in a manner indicating that the material of the pad at opposing sides will also be urged in opposite directions. The pad is, of course, squeezed by foot pressure thus compacting and spreading the material. The angled wire ends entering the material thus will tend to follow the direction of the tips as the material is penetrated. It may also be noted that when the foot is placed on the top of the base and pressed downwardly the foot can also be moved with a forward and backward push so that the wires penetrate more deeply into the body of the pad material in the direction of the angled tips. In FIG. 5 after foot pressure is released, the wire prongs will then return insofar as possible to the free hanging position of FIG. 3. After being embedded, however, in the upper section of the material of the pad the angled tip ends will tend to hook into the material and retain the bite of the prongs on opposite sides. With a crinoline backing, as the backing 25, the prongs will particularly cling to the upper surface of the pad 24. Thus the pad will be held by the gripping wires suiliciently to cling against the undersurface of the holder for use of the assembled mop in a conventional manner. In use and particularly when used as a wet mop or for waxing purposes the frictional rubbing action of the pad on the surface assists in the gripping action of the prong ends. Being of loose fibrous construction, the pad may be removed from the holder merely by grasping an edge of the pad and stripping or peeling it from the prongs. A pad of loose fibrous material or cellular sponge rubber construction may be so stripped without undue tearing of the material. Accordingly, the pad may be cleaned by shaking or rinsing and then replaced on the holder for reuse until it becomes worn out.
The wire prongs as seen from the sectional view of FIG. 4 are held by a resilient backing 28 which preferably comprises a relatively thick closely Woven fabric or canvas type of material such as is commonly used in card clothing for textile carding machinery. The wires are relatively stiff with sharpened tip ends being stapled in pairs and held by the resilient heavy fabric backing for desirable flexing action. The backing 28 is suitably secured to the base as by an adhesive.
It will also be appreciated that in addition to an integral formation of the base member 2 as above mentioned, it is also contemplated that a unitary base member with sections of needle-like integrally molded plastic prongs may be provided. Stily flexible prongs of this type will operate to cling to a pad in the same manner as described. It should further be noted that the arrangement of spacer sections 22 between prong sections 20 may also be varied, and that so long as groups of prongs are arranged with oppositely angled tip end portions along opposite sides of the holder a pad of loose fibrous construction or cellular rubber or foam will be held thereby.
What is claimed is:
1. A holder for mop pads and the like comprising a sti base member, a heavy backing of resilient material carried by said base member against the underside thereof and a plurality of spaced needle-like depending wire prongs carried by said backing material, said backing material being divided into at least three spaced sections at said underside of the base, the portions between said backing material carrying sections of readily compressible cellular sponge material adhesively secured thereto, the prongs at one side of said base being angularly bent with the tip ends facing in one direction and the prongs at the other side of the base being similarly bent and facing in the opposite direction, said sections of sponge material extending below the tips of said prongs.
2. A holder for mop pads of loose fibrous construction and the like comprising a stiff base member of rectangular shape and at the underside thereof a series of spaced transversely disposed sections having a heavy backing of resilient material mounted thereagainst, a plurality of closely spaced rows of depending wire prongs carried by said backing material, the prongs at one side of the base being angularly turned and the lower ends facing in one direction, the prongs at the other side of the base being similarly angularly turned with lower ends facing in the opposite direction, and sections of readily compressible sponge rubber being mounted between said spaced prong sections against said underside of the base, the lower surface of said sponge rubber sections lying below the plane of the lower ends of said prongs.
