Surface cleaning device

Abstract

The present invention is concerned with an improved surface cleaning device. The device has a utility portion for engaging a surface to be cleaned and a handle portion connected to the utility portion. The utility portion defines a lower surface facing a surface to be cleaned, and is adapted to accommodate a sheet of cleaning substrate for covering the lower surface and contacting a surface to be cleaned in use. The utility portion includes a plurality of projection members protruding from the lower surface for providing one or more raised regions on the cleaning sheet substrate which otherwise is fitted against the lower surface, such that in use the one or more raised regions are accessible to recessed area of a surface to be cleaned.

1 . A cleaning device comprising a utility portion for engaging a surface to be cleaned and a handle portion connected to the utility portion, the utility portion defining a lower surface facing a surface to be cleaned, and adapted to accommodate and secure a sheet of cleaning substrate with an inwardly facing surface for covering the lower surface of the utility portion of the cleaning device and an outwardly and non-planar facing surface for contacting a soiled surface to be cleaned in use, wherein the utility portion includes a plurality of projection members protruding from the lower surface for providing one or more regions on the cleaning sheet material raised by the projection members, the cleaning sheet substrate otherwise is fitted against the lower surface, such that in use the cleaning substrate with the one or more raised regions is conformable and accessible to recessed area of the soiled surface to be cleaned. 
     
     
         2 . A device as claimed in  claim 1 , wherein the projection members are in the form of fingers, bristle tufts, bumps or a squeegee. 
     
     
         3 . A device as claimed in  claim 2 , wherein the projection members are made of stiff plastics or polymeric materials. 
     
     
         4 . A device as claimed in Clam  2 , wherein the projection members are made of a material selected from a group including polypropylene (PP), polybutylene terephthalate (PBT) and polyamide (PA). 
     
     
         5 . A device as claimed in  claim 2 , wherein the projections members are arranged linearly. 
     
     
         6 . A device as claimed in  claim 2 , wherein the projection members are arranged linearly in substantially straight configuration across the lower surface of the utility portion. 
     
     
         7 . A device as claimed in  claim 5 , wherein the plurality of projections is arranged in at least one row. 
     
     
         8 . A device as claimed in  claim 7 , wherein the plurality of projections is arranged in three rows only. 
     
     
         9 . A device as claimed in  claim 7 , wherein the plurality of projections is arranged in one row only. 
     
     
         10 . A device as claimed in  claim 7 , wherein the row or rows of projection members extend laterally across the utility portion, and is perpendicular to forward and rearward movement of the utility portion in use. 
     
     
         11 . A device as claimed in  claim 7 , wherein the row or rows of projections extend from a front end to a rear end across the utility portion, and is parallel to forward and rearward movement of the utility portion in use. 
     
     
         12 . A device as claimed in  claim 1 , wherein the projection members protrude from the lower surface perpendicularly. 
     
     
         13 . A device as claimed in  claim 1 , wherein the projection members protrude from the lower surface at an angle. 
     
     
         14 . A device as claimed in  claim 1 , comprising a strip member from which the projection members protrude, wherein the strip member is connected to the utility portion. 
     
     
         15 . A device as claimed in  claim 14 , wherein the strip member is connected to the utility portion by snap-fitting, glue, welding or screwing thereto. 
     
     
         16 . A cleaning system comprising a cleaning device as claimed  claim 1  and a sheet of cleaning substrate fittable or fitted to the cleaning apparatus, the utility portion and the sheet cleaning substrate together is adapted to conform to a three-dimensional surface, reach recess or grout area of a surface, or reach area between a wall and a floor, to be cleaned. 
     
     
         17 . A cleaning apparatus comprising a utility portion for engaging a soiled surface to be cleaned in use, a handle portion pivotably connected to the utility portion, and a sheet of cleaning substrate;
 wherein the utility portion defines a lower surface, and includes means adapted to accommodate the sheet of cleaning substrate with one surface for covering the lower surface of the utility portion and an external surface for contacting the soiled surface to be cleaned and a plurality of projection members at the lower surface for providing one or more regions on the cleaning sheet material raised by the projection members, the cleaning sheet material otherwise is fitted against the lower surface, such that in use the one or more of the raised regions acting as pressure points are accessible to recessed area of a surface or a three-dimensional surface to be cleaned.   
     
     
         18 . A cleaning apparatus as claimed in  claim 17 , wherein the plurality of projections is arranged linearly at the lower surface.
