Mop with removable interchangeable work pads

Claim 2

A mop comprising an elongated handle and a flat rectangular support plate having a perimeter and a top surface and a bottom surface, a universal joint means connecting said handle to said top surface, said bottom surface being planar and having four corners, each corner only containing a thin pad of fabric hooks with the remainder of said bottom surface being clear of any fabric hooks, a removable work pad being flexible and having a rectangular perimeter and extending outwardly beyond said perimeter of said support plate, said work pad having an upper planar layer of a non-woven fabric fastenable to said pads of fabric hooks, a central planar layer of a foamed synthetic plastic material, and a lower planar layer of a selected sheet material adapted to be used in a mopping operation, said corners of said bottom surface of said support plate, having square shallow depressions therein, said pads of fabric hooks being square and positioned in and filling respective said shallow depressions in said bottom surface of said support plate, said depressions being of a depth to permit said pads to extend generally half their thickness above said bottom surface of said support plate and to dispose said upper planar layer of said work pad flat against said bottom surface of said support plate and said pads of fabric hooks, and to dispose said lower layer of said work pad to be substantially planar when said upper layer is attached to said plate.

Claim 3

The mop of claim 1 wherein said central layer and said upper layer are laminated and said lower layer is stitched to said central and upper layers around said perimeter of said work pad, and forming a work pad about 1/4 to 3/4 inch thick.

Claim 4

The mop of claim 2 wherein said lower layer of said work pad is terry cloth.

Claim 5

The mop of claim 2 wherein said lower layer of said work pad is abrasive.

Claim 6

The mop of claim 2 wherein said lower layer of said work pad has a shaggy texture.

Claim 7

A mop with a plurality of interchangeable work pads comprising an elongated handle having opposite ends, a flat rectangular support plate having a perimeter and a top surface and a bottom surface, universal joint means for connecting one of said ends of said handle to said top surface, said bottom surface being planar and having four rectangular corner areas, a thin rectangular sheet member of fabric hooks disposed in each said corner areas with its hooks exposed adjacent said bottom surface, each said work pad being flexible and rectangular and extending outwardly of said perimeter of said support plate, said work pad having an upper planar layer being composed of a non-woven fabric fastenable to said sheet members of fabric hooks, a central planar layer of a foamed synthetic plastic material laminated to said upper layer, and a lower planar layer of a selected sheet material carried by said upper and central layers, said work pad being stitched around its perimeter to join together said lower planar layer to said laminated upper and central planar layers, said corner areas of said support plate being recessed upwardly to form shallow depressions, said sheet members of fabric hooks being positioned in said shallow depressions of said corner areas of said support plate with their hooks extending slightly below said bottom surface, said depressions being of a depth to permit said planar upper layer of said work pad to remain substantially planar when said upper layer is attached by said sheet members of fabric hooks to said support plate and said lower planar layer of said work pad being parallel therewith.

Claim 8

A mop with a plurality of interchangeable work pads comprising an elongated handle having opposite ends, a flat rectangular support plate having a perimeter and a top surface and a bottom surface, universal joint means for connecting one of said ends of said handle to said top surface, said bottom surface being planar and having four rectangular corner areas, a thin rectangular sheet member of fabric hooks disposed in each said corner areas with its hooks exposed adjacent said bottom surface, each said work pad being flexible and rectangular and extending outwardly of said perimeter of said support plate, said work pad having an upper planar layer being composed of a non-woven fabric fastenable to said sheet members of fabric hooks, a central planar layer of a foamed synthetic plastic material laminated to said upper layer, and a lower planar layer of a selected sheet material carried by said upper and central layers, said work pad being stitched around its perimeter to join together said lower planar layer to said laminated upper and central planar layers, said corner areas of said support plate being recessed upwardly to form shallow depressions, said sheet members of fabric hooks being positioned in said shallow depressions of said corner areas of said support plate with their hooks extending slightly below said bottom surface, said depressions being of a depth to permit said planar upper layer of said work pad to remain substantially planar when said upper layer is attached by said sheet members of fabric hooks to said support plate and said lower planar layer of said work pad being parallel therewith.

Claim 9

The mop of claim 6 wherein said lower layer of one said work pad is terry cloth.

Claim 10

The mop of claim 6 wherein said lower layer of one said work pad is abrasive.

Claim 11

The mop of claim 6 wherein said lower layer of one said work pad includes a multiplicity of long fibers used for dusting.

Claim 12

The mop of claim 6 wherein said lower layer of one said work pad is terry cloth, said lower layer of a second said work pad is abrasive and said lower layer of a third said work pad includes a multiplicity of long fibers used for dusting.
