Door or shoe mat

Claim 1

A door mat comprising a molded one-composite material having a bottom base portion with top and bottom surfaces, flexible projections being integrally formed with the top surface of the base and extending upwardly therefrom with which wiping action can be effected upon the bottom of a shoe sole, annularly inter-connecting base ridges extending upwardly from and integral with each of adjacent flexible projections providable of upright reinforcement support such that said projections are substantially rigidly self-supporting but adapted to be flexed under the weight of a foot-worn shoe; upstanding non-flexible scraper-projections with an upper top surface having a plurality of upwardly directed separate scraper sharp edges integrally fused laterally to one another such that hard or fastened debris on a shoe sole is readily scraped by the non-flexible projections being dispersed through the flexible projections and rising upwardly to less than the height of the free and extended flexible projections and adapted for full weight of a foot-worn shoe being placed opon the mat to support the weight of the foot-worn shoe and at the same time providing means upon which heavier and concentrated wiping action can be effected upon the more adhered debris upon the shoe sole and while the flexible projections still lie in contact with the shoe sole for light wiping action thereupon, said flexible projections being formed in clusters with the individual projections being circularly arranged thereabout and circumferentially spaced from one another, each of the projections extending upwardly from a common base and being of tapering section and having its ends overlying a plane extending between the surface of the upper ends of the non-flexible projections, the diameter of the clusters being generally the same diameter as the non-flexible projections, the clusters and the non-flexible projections being spaced from one another to support a foot sole under its full weight without depressing the flexible projections below the plane extending across the top surface of the non-flexible projections, and in which the plurality of scraper sharp edges of the non-flexible projections are formed as ridges with notches alternately angularly spaced between adjacent ridges of said non-flexible projections upper top surfaces and the plurality of notches and ridges extending radially outwardly from the center of the top surface of the rigid projections and being formed as part of the rigid projections providing thereby sharp rigid scraping edges.
