COMPLETE SPECIFICATION FOR THE INVENTION SITITLR):- "1HAND-HELD UTENSIL FOR SURFACE CLEANING, MOPPING AND THE LIKE" The following statement Is a foUl des=riptio& of this inventione Including the best method of performing it known to usla f HAND-HELD UTENSIL FOR SURFACE CLEANING, MOPPING AND THE LIKE The present invention relates to utensils for surface cleaning, mopping and the like and to replaceable pads for such utensils and in particular, although not exclusively, to a hand-held utensil for domestic cleaning use.

Pads of material, particularly absorbent material 1 0 such as cloths and sponges have been used for many years to Sclean, mop, scour and polish surfaces such as floors and kitchen units. Conventional sponge floor mops are well known which are operated from waist level by means of a broomstick-like handle; usually the handle is provided with 15 a mechanism which enables the user to wring out the sponge.

The present invention is based upon an appreciation of the fact that it would be desirable to provide an improved hand-held utensil for these and other purposes.

Thus, the present invention provides a hand-held utensil for surface cleaning, mopping and the like comprising a pad of suitable surface-treatment material and a holder for the pad, the holder comprising parts which are movable relative to one another from a first position in which the pad is used in normal use of the utensil to a second position in which the parts squeeze the pad, the holder parts having respective handles adapted to be directly gripped by the user and to enable the user to move the parts from the first, working position to the second position, and wherein the handles, in the first position of ;the holder parts, co-operate to form a handle arrangement extending along the holder which serves as a grip to enable the user to hold the utensil in its normal use.

As distinct from a conventional floor mop, therefore, the presently proposed utensil is adapted to be T ;7f ~i z ad

2 held directly in the hand, this being based on an appreciation of the fact that for floor cleaning purposes, a significant proportion of users would prefer a utensil that requires them to bend down and exert effort directly at the point of cleaning rather than use a mop from waist level.

The handles on the holder parts further enable the user to exert effort for wringing the pad directly on the pad rather than via the articulated type of mechanism found in conventional floor mops although of course for specific 10 purposes an articulated mechanism may be provided to operate the handles, as for example where the utensil is provided on a handle to increase its reach, eg, for cleaning windows.

The pad may be made from any suitable material, such as a cloth or sponge, the particular material being determined by the use to which the utensil is to be put, eg, a cloth for polishing, an absorbent or non-absorbent sponge, such as an artificial sponge, for cleaning and mopping etc, a scouring pad for scouring or a natural or synthetic chamois leather for window cleaning and similar purposes, or a bristled or textured surface for brushing and similar. It I a' I C tcC I Ic it c It It C I I C t IC -3will be appreciated that a single holder may be provided with a number of different types of pad releasable appropriate for different purposes such as cleaning, scouring, polishing, mopping etc.

The holder may be made of any suitable rigid material, such as metal, plastics or wood, although typically plastics will be used since it is a convenient material to use for mass production.

Preferably the holder comprises such holder parts which are hinged or otherwise articulated together; this may be by means of an integral hinge, so that the two parts may S4 1 49 be swung towards one another thereby squeezing the pad.

For use with pads to be used in applications which require an efficient wringing action, such as a sponge, the SC 15 width of the hinge is important, in particular so as to enable the areas of the pad furthest from the hinge line to be pressed together to a sufficient degree to provide effective wringing. Preferably, the hinge width is between 0 and twice the thickness of the pad; for example, a synthetic or cellulosic sponge pad of 23 mm thickness, a SE hinge wi'th of 20 mm has been found to be optimum.

Particularly for floor cleaning and similar applications, the shape of the pad is significant.

Specifically it has been found to be desirable for the two end areas to have converging lateral edges with an included angle of 90° or less, preferably about 700, so as to provide a tapering end which facilitates cleaning into corners., -4- These lateral edges may be straight or rounded. T.o overlying portions of the holder parts may be correspondingly shaped.

The handles of the holder parts also serve as a grip or grips to enable the user to hold the utensil in its normal use. For example, when the utensil is in its position of normal use, the holder parts may co-operate to form a handle extending along the holder. The two handle means may overlap lengthwise of the holder and abut side by 10 side in their overlapping regions to form a grip which the user uses to hold the utensil in use.

The handles may be attached Lo the holder parts; for example, each of the handles may comprise a first part attached to and extending upwardly away from the associated holder part, and a second part extending over the associatea holder part and towards and over the other holder part. The parts of the handles which extend towards the other holder part may overlap as described above to form a single grip.

For ease of use the grip formed by the two handles 20 may be spaced from the holder parts, providing a gap to accommodate the user's knuckles when gripping the utensil.

To maintain the holder in its first position during use, a latch or detent may be provided, suitably on the handle. In the case that the handles overlap with one another, the latch or detent may be provided on this overlapping region.

i The pad of surface-treatment material may be permanently fixed, or releasably and replaceably attached, to the holder. In the latter case, the releasable attachment may be achieved by co-operating means on the holder parts and the pad; for example, the pad and/or the holder may be provided with resiliently deformable elements, preferably located in the region of the holder parts where the corresponding handle means are attached, or the pad may be provided with a resiliently deformable rim which can be fitted over the edges of the holder parts or vice versa.

Alternatively any other releasable systems such as screws, other resilient clips, and so forth maybe used.

Although generally a unitary pad will be attached to the two holder parts, the pad may be in two or more parts separated at the hinge); these parts may be attached to a common backing which carries the fixings for attaching -j the pad as a whole to the holder. Further, where the pad is in two parts, the parts may be of different material e.g. an absorbent sponge part on one holder part, and a scouring or abrasive part on the other holder part to give a dual cleaning and scrubbing action.

In the position of normal use, the holder parts of the utensil preferably lie along a single plane, and the pad attached to the holder parts also lies along this plane, and since the lower surface of the pad to be used for cleaning,

J

6 mopping, scouring, polishing, etc, will generally be parallel to the surface of the holder parts to which the pad is attached, in its normal use position this lower surface of the pad used for cleaning, etc, will be planar.

Auxiliary functions such as brushing or scraping may be provided by means of formations or attachments on the holder. For example a ridge of tough material may be provided on the front part of one of the handle means to act as a scraper for use in removing dirt etc, encrusted on the surface to be cleaned.

The invention will now be further described with reference to the attached drawings in which: Figure 1 shows a side view of the utensil in its first position, that in which it is normally used; Figure 2 shows a side view of the utensil in an intermediate position; 1~iI i I- r i ,11 -7- Figure 3 shows the utensil in its second p'cition in which the pad is squeezed; Figure 4 shows a plan view of the utensil of Figure ii 1; Figure 5 is a sectional view of the pad illustrafing the clipping arrangement by ieans of which the pad is releasably attached to the holder; and Figures 6 and 7 illustrate alternative versions of the holder part of the utensil.

I 10 Figures 1 to 5 show an embodiment of the invention incorporating the various features above described. The utensil comprises a holder 1 to which is releasably attached by means of resiliently deformable clip tabs 10a,10b, a pad of sponge or other material suitable to the purpose of the utensil, in this case floor cleaning. The holder I comprises two generally similar holder parts respectively comprising mounting plates lA, 1C for the pad 5, these beng articulated together by means of two parallel integr-l hinges 2 disposed to either side of a relatively narrow central strip-like part 1B, and handles 3A, 3B which cu:rve the dual functions of a) providing operating handles enabling the user to pivot the parts 1A, 1C towards one another to squeeze or wring out the pad 5 and b) providing a handle in the unpivoted, Figure 1, condition by means of which the user can hold the utensil and use it to wipe the floor.

L i 8- Figure 4 shows a plan view of the utensil in the Figure 1 condition illustrating how, when the utensil is in the position for normal use, the two handle parts 3a, 3b co-operate to form the handle 4. The handle parts 3a, 3b comprise respective portions Ga, 6b by means of which they are attached to the plates la, lb and portions 7a, 7b which overlap one another lengthwise of the holder and, being disposed in side by side abutting relation in the Figure 1 condition, form the handle 4 extending along the utensil in spaced relation to the plates la, ib, lc to leave a gap to accommodate the user's knuckles when gripping the utensil.

The handle parts 3a, 3b are provided with means whereby they may be latched in the Figure 1 condition this may be achieved, for example by means of a pair of ball-and-socket detents on the two overlapping handle parts 7a, 7b.

Figure 4 also illustrates how the holder parts and the pad are symmetrical about the hinge of the holder and how the cuter ends of the plates la,lc and the pad are provided with converging side edges as at lla,llb so that each end of the utensil tapers to a point, preferably with an included angle of 70 or thereabouts, to facilitate cleaning into corners. The tips of the ends of the holdrt parts may be rounded or blunted to avoid the risk of damaging surfaces.

-r at least in the case of a sponge pad, and that the hinge ic provided with two parallel hinge lines rather than a sinigl one. This can avoid the part of the pad closest to tho hinge needing to be overly compressed in order to compress and wring the parts of the pad further from the hinge.

Figure 2 shows the utensil in an intermediate position between the first position and the second position, when the sponge is to be filled, rinsed or replenished. The handle means 3 are separated and the hinges 2 swung so that two of the base plates, la and 1c, are moved towardc one another thereby folding the sponge 5 in on itself.

Figure 3 shows the utensil in its second psition, and here the sponge is being squeezed and the handle mean 3 are gripped by the user and used to press the holder parto la and Ic together thereby squeezing liquid out of the aponge. The provision of the strip-like part IB relioves the squeezing action on the part of the pad 5 uloe; .t the point of pivoting.

The Figures also show a scraper 8 provided ao a Sraised ridge on one of the handle parts 3a, 3b.

Figure 5 illustrates an example of the preferr clipping arrangement whereby the pad 5 is releasably attached to the holder. To each side of the hinge is a semi-rigid body 12 of e.g.

plastics material secured to the pad 5, for instancr but not necessarily by gluing and having projecting from its surface the resiliently deformable clip tabs 10a,10b which spring into engagement with correspondingly shaped apertures in the side walls of the handles 3 (Fig 1).

The clip-tabs 10a,10b are shaped and dimensioned to correspond approximately with the size of the pad ofE typical user's thumb, e.g. they can be about 2 cm widre and about 1.5 cm high, and placed at the junctions of the handle parts 6a,6b (Fig 4) and the plates la,lc so as to provide a natural and convenient grip between the user's thumb and opposed forefinger.

Conveniently, foc optimum efficiency of the wrinring action, the underside of the holder in shaped complementarily to the upper surface of the pad, ieludin the body 12. They need not, however, be exactly complementary; in particular the plates la,lc may b. riO(q-d to provide a compromise between material usage and rigidity.
