Sponge squeegee combination

Abstract

A car-cleaning implement (1) comprises a spongy resiliently-flexible liquid-absorbent block (2) having an exposed face (3) for applying soapy water, and its opposite face sheathed with a thin flexible skin (4) which is not water absorbent and is formed with parallel ribs (5) extending between opposite ends of the block. By inverting the block after washing off the soapy water, the ribbed skin can be used to remove water droplets from the painted surface of the car without streaking.

FIELD OF THE INVENTION THIS INVENTION relates to the washing of extended surfaces open to atmospheric pollution and grime, and is specifically, although not exclusively, concerned with hand-cleaning the paint-work of a motor vehicle. STATE OF THE ART The conventional way of cleaning the paint-work of a motor vehicle by hand, is to sponge down the paint-work with water, apply a cleaning agent such as a detergent or soap to the paint-work with a sponge and plenty of water, wash down the paint-work after cleaning with plenty of water usually supplied by a hose, and finally wiping residual spots of water from the paint work with a chamois leather which removes any free surface water from the paintwork. OBJECTION OF THE INVENTION An object of the invention is to provide an improved implement for cleaning an extended surface by hand. SUMMARY OF THE INVENTION According to the present invention an implement for cleaning grime from an extended surface susceptible to atmospheric pollution, comprises a resiliently-flexible block of relatively water-absorbent, spongy material having one face exposed for applying a cleaning solution such as soapy water to the surface to be cleaned, and the opposite face sheathed with a resiliently-flexible, externally-ribbed skin of material which is relatively non-absorbent to water. The implement enables the cleaning solution to be hand-applied by way of the exposed face of the spongy block, and, after the cleaning solution has been washed off with clean water, residual drops of the water are removed by wiping the ribbed face of the block across the surface. The ribs on the face flex to conform to the contour of the surface beneath the block and act with a squeegee action to provide dams which remove water droplets from the area of the surface over which the ribbed face of the block is passed, so that the water droplets are removed and a clean and virtually drop-free surface emerges from beneath the block. PREFERRED FEATURES OF THE INVENTION In the preferred form of the invention the block has a flat rectangular face on one side, and its opposite side is of generally semi-cylindrical shape and is sheathed with the ribbed skin. The ribs of the skin conveniently extend parallel to one another between opposite end-faces of the block so that they are wiped across the paint surface in a direction which is transverse to the direction in which the ribs extend. However, it is not essential for the ribs to be continuous. Experiments have shown that the implement works equally well where the ribs are interrupted or are of non-linear shape such as S-shape, or U-shape. As one possible example of the shape of ribs which is useable it was found that ribs in the form of overlapping capital letters spelling out the name of the manufacturer and using the letters in staggered lines provided a satisfactory squeegee action. Whatever shape is chosen for the ribs, it is preferred that there is continuous band of the ribbed skin in contact with the paint surface when the water droplets are being wiped off, to prevent the droplets leaving streak-lines on the paint-work behind the implement. Suitably the sheath covers the bulk of the generally semi-cylindrical shaped face of the sponge so that the sheath provides a hand-hold for the block and prevents liquid absorbed into the spong from flooding out over the hand of the user when the cleaning solution is being applied. The semi-cylindrical shape of the block facilitates the ability of the block to perform a partly wiping action and partly rolling action, as the user's wrist turns naturally during the wiping movement of the block over the surface being cleaned. INTRODUCTION TO THE DRAWINGS The invention will now be described in more detail, by way of examples, with reference to the accompanying partly diagrammatic drawings, in which: FIG. 1 is a top perspective view of a spongy implement for cleaning a painted surface; FIG. 2 is an under plan view of the implement; FIG. 3 is an end view of the implement, both ends appearing the same; FIG. 4 is a top plan view showing a further design of ribbing on the sheath; FIG. 5 is a top plan view of an implement with yet another shape of ribbing on the sheath; and FIG. 6 shows the implement of FIG. 5 in use wiping surplus water drops from the painted surface of part of a motor vehicle. DESCRIPTION OF PREFERRED EMBODIMENT FIG. 1 shows a cleaning implement 1 which is about 215 mm. long, 105 mm. wide and 75 mm. high. It comprises a soft, resiliently flexible, sponge block which is water absorbent and which has a flat rectangular face 3 shown in FIG. 2. The opposite face of the block is a generally semi-cylindrical shape to provide a comfortable hand-hold, and is sheathed with a non-absorbent resiliently flexible skin 4 which is 2 mm. thick. The skin 4 is provided with external parallel ribs 5 about 2 mm. high and which have a V-shaped section as shown in FIG. 3. the block is made from an open-cell foam of soft polyurethane, and the skin 4 is made form closed-cell ethylene vinyl acetate foam. The skin is cemented to the block by a waterproof adhesive which when applied, does not degrade the skin 4 or the surface of the block 2. VARIATIONS OF PREFERRED EMBODIMENT As appears from FIGS. 4 and 5 the ribs 5 provided on the skin 4 can have different shapes without detracting from the usefulness of the invention. In FIG. 4 the ribs are interrupted to provide short rib sections 6 which are staggered with respect to the lines of short rib sections in the adjacent rib lines. In FIG. 5 the ribs are formed by S-shape rib sections 7 arranged in lines and staggered with respect to the ribs in neighbouring lines. In a further embodiment (not shown) the rib sections are of C-shape with successive rib sections in each line facing in opposite directions respectively, and the rib sections in adjacent lines being staggered with respect to one another. In another non-illustrated embodiment, the block 2 is of parallelepiped shape and has one rectangular face exposed, and the other, opposite, rectangular face and adjacent portions of the longer sides of the block sheathed with the skin which effectively provides two parallel ribs where it extends over the corners at the longer sides of said opposite face. The end faces of the block may also be sheathed with the skin if desired. USE OF THE IMPLEMENT FIG. 6 shows the implement in use to remove water droplets from the painted surface of a motor vehicle body. The vehicle body has a curved contour but the flexibility of the implement enables it to mould itself naturally to the painted surface under hand pressure, so that the ribs provide dams which prevent the water droplets from passing beneath the skin 4 of the implement as it is passed over the wet curved painted surface of the vehicle. The painted surface is thus wiped dry in much the same way as if the water droplets had been removed by a chamois leather using the conventional technique.
