Abstract

Abstract A cleaning tool uses a block of foamed resin material having a scrubbing face and a recessed, stiff pile material arranged adjacent the scrubbing face so that when the block is pressed lightly, only the soft scrubbing face engages the surface to be cleaned, and when the block is pressed harder, the foam material is compressed, and the pile material is brought into scouring contact with the surface to be cleaned.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 186 words
A cleaning tool comprising: a. a block of foamed resin material; b. said block having a generally plane scrubbing face region disposed for scrubbing movement over a surface to be cleaned; c. said block having a generally plane scouring region adjacent said scrubbing face; d. said scouring region being recessed relative to said scrubbing face so that said scouring region lies in a different plane from that of said scrubbing face; e. said plane of said scouring region being disposed at an acute angle to said plane of said scrubbing face; f. a generally plane piece of coarse and stiff pile material having the size and shape of said scouring region; and g. means for securing said pile material to said scouring region so the tips of the pile elements of said material are recessed relative to said scrubbing face allowing said tool to be used with relatively light pressure to move only said scrubbing face over said surface to be cleaned and to be used with relatively heavy pressure to compress said resin material and bring said pile material into scouring contact with said surface.
Claim 2
Dependent Claim 186 words
A cleaning tool comprising: a. a block of foamed resin material; b. said block having a generally plane scrubbing face region disposed for scrubbing movement over a surface to be cleaned; c. said block having a generally plane scouring region adjacent said scrubbing face; d. said scouring region being recessed relative to said scrubbing face so that said scouring region lies in a different plane from that of said scrubbing face; e. said plane of said scouring region being disposed at an acute angle to said plane of said scrubbing face; f. a generally plane piece of coarse and stiff pile material having the size and shape of said scouring region; and g. means for securing said pile material to said scouring region so the tips of the pile elements of said material are recessed relative to said scrubbing face allowing said tool to be used with relatively light pressure to move only said scrubbing face over said surface to be cleaned and to be used with relatively heavy pressure to compress said resin material and bring said pile material into scouring contact with said surface.
Claim 3
Dependent Claim 20 words
The tool of claim 9 including a squeegee extending along said block in a region spaced from said scrubbing face.
Claim 4
Dependent Claim 26 words
The tool of claim 1 wherein said scouring region is arranged along one edge of said block, and said block is mounted on a detachable mophead.
Claim 5
Dependent Claim 20 words
The tool of claim 2 including a squeegee extending along said block in a region spaced from said scrubbing face.
