Abstract
Abstract A floor mat having a thin perforate water-absorbent top layer for wiping the feet on. An intermediate spongy layer receives water, but no appreciable dirt, from the top layer and also reinforces the top layer against side loads. An imperforate tray supports both layers and serves as a water receptacle. Ribs on the tray assist in preventing sliding of the intermediate layer thereon. The tray is snap fit onto a clamping frame which also holds the edge portions of both layers in place.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
176 words
A floor mat comprising, in combination: a. a thin top sheet for wiping the feet thereon, said top sheet being penetrable by water but relatively impenetrable by particles of dirt, b. an intermediate sheet of resilient spongelike material disposed beneath and supporting said top sheet and with said intermediate sheet being constructed to hold water therein which has passed downwardly from said top sheet, c. said top sheet being provided with a plurality of small openings therein, said openings providing surface roughness for trapping dirt particles scraped thereagainst as well as providing direct passage means for water to flow downwardly to said intermediate sheet, d. said intermediate sheet being of the open cell type so that water can pass therethrough, the surface of said intermediate sheet being of relatively rough texture, e. a moisture tray disposed beneath and supporting said intermediate sheet, said tray being imperforate and constructed as a receptacle means for water which has passed downwardly from said intermediate sheet, f. and means removably securing said tray and sheets together into a complete assembly.
Claim 2
Dependent Claim
176 words
A floor mat comprising, in combination: a. a thin top sheet for wiping the feet thereon, said top sheet being penetrable by water but relatively impenetrable by particles of dirt, b. an intermediate sheet of resilient spongelike material disposed beneath and supporting said top sheet and with said intermediate sheet being constructed to hold water therein which has passed downwardly from said top sheet, c. said top sheet being provided with a plurality of small openings therein, said openings providing surface roughness for trapping dirt particles scraped thereagainst as well as providing direct passage means for water to flow downwardly to said intermediate sheet, d. said intermediate sheet being of the open cell type so that water can pass therethrough, the surface of said intermediate sheet being of relatively rough texture, e. a moisture tray disposed beneath and supporting said intermediate sheet, said tray being imperforate and constructed as a receptacle means for water which has passed downwardly from said intermediate sheet, f. and means removably securing said tray and sheets together into a complete assembly.
Claim 3
Dependent Claim
43 words
The floor mat of claim 1 which includes friction increasing means at the interface between said moisture tray and said intermediate sheet to reduce sliding of said latter sheet on said tray upon application of forces parallel to the plane of the mat.
Claim 4
Dependent Claim
7 words
a rib extending downwardly from said frame.
Claim 5
Dependent Claim
7 words
a rib extending downwardly from said frame.
Claim 6
Dependent Claim
25 words
and a pluRality of multidirectional raised ribs in said surface which support said intermediate sheet and reduce sliding of said latter sheet on the tray,
Claim 7
Dependent Claim
25 words
and a pluRality of multidirectional raised ribs in said surface which support said intermediate sheet and reduce sliding of said latter sheet on the tray,
Claim 8
Dependent Claim
32 words
the edge portion of said tray curving downwardly to form a downwardly extending edge, d. and means removably securing said tray and sheets together into a complete assembly, said securing means comprising:
Claim 9
Dependent Claim
32 words
the edge portion of said tray curving downwardly to form a downwardly extending edge, d. and means removably securing said tray and sheets together into a complete assembly, said securing means comprising:
Claim 10
Dependent Claim
14 words
a plurality of spaced lugs snap-fittingly locking the said downwardly extending tray edge thereover,
Claim 11
Dependent Claim
14 words
a plurality of spaced lugs snap-fittingly locking the said downwardly extending tray edge thereover,
Claim 12
Dependent Claim
31 words
The floor mat of claim 2 in which said friction increasing means comprises a plurality of multidirectional edges raised from the surface of said tray and engaged by said intermediate sheet.
Claim 13
Dependent Claim
26 words
The floor mat of claim 2 in which said friction increasing means comprises a rough sandylike surface on said tray and engaged by said intermediate sheet.
Claim 14
Dependent Claim
13 words
and a plurality of spaced nibs penetrating through said top and intermediate sheets.
Claim 15
Dependent Claim
13 words
and a plurality of spaced nibs penetrating through said top and intermediate sheets.
Claim 16
Dependent Claim
99 words
A floor mat comprising, in combination: a. a thin top sheet for wiping the feet thereon, said top sheet being penetrable by water but relatively impenetrable by particles of dirt, b. an intermediate sheet of resilient spongelike material disposed beneath and supporting said top sheet and with said intermediate sheet being constructed to hold water therein which has passed downwardly from said top sheet, c. a moisture tray disposed beneath and supporting said intermediate sheet, said tray being imperforate and constructed as a receptacle means for water which has passed downwardly from said intermediate sheet, said moisture tray comprising:
Claim 17
Dependent Claim
99 words
A floor mat comprising, in combination: a. a thin top sheet for wiping the feet thereon, said top sheet being penetrable by water but relatively impenetrable by particles of dirt, b. an intermediate sheet of resilient spongelike material disposed beneath and supporting said top sheet and with said intermediate sheet being constructed to hold water therein which has passed downwardly from said top sheet, c. a moisture tray disposed beneath and supporting said intermediate sheet, said tray being imperforate and constructed as a receptacle means for water which has passed downwardly from said intermediate sheet, said moisture tray comprising:
Claim 18
Dependent Claim
37 words
The floor mat of claim 5 wherein said raised ribs are formed by concave depressions in the bottom surface of said tray, and which includes a rubberlike mat-supporting foot disposed in at least one of said depressions.
