Abstract
Abstract A floor mat construction of rubberized material including a base and feet of barbell-like configuration which extend integrally downwardly from the underside of the base for the support thereof in upwardly spaced relation on a supporting surface. A plurality of apertures the upper ends of which are of substantially hexagonal configuration, extend through the base to define a hexagonal honeycomb-like configuration in the upper portion thereof. The mat is lightweight but structurally efficient, the upper surfaces of the common walls between the hexagonal upper ends of the apertures providing durable scraping surfaces for a nonskid effect, and the feet firmly gripping the supporting surface therebeneath to resist creeping of the mat.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
A floor mat construction comprising: (a) a base made of a rubberized material and having a plurality of apertures therethrough, the upper portions of said aperture being of multisided geometric configuration, said apertures being disposed in adjacent offset rows wherein each of the sides of the upper portions of said apertures, other than those in the peripheral rows on said base, define common walls with adjacent sides of the upper portions of adjacent apertures so that said apertures cooperate to define a honeycomb-like configuration in said base; and (b) a plurality of resiliently flexible spaced feet extending integrally downwardly from the underside of said base to maintain said base in slightly upwardly spaced relation to a supporting surface when positioned thereon, said feet having substantially flat bottom surfaces and being of elongated barbell-like sectional configuration wherein the transverse sectional dimensions of said feet are greater in the opposite end portions thereof than in the central portions thereof.
Claim 2
Dependent Claim
157 words
A floor mat construction comprising: (a) a base made of a rubberized material and having a plurality of apertures therethrough, the upper portions of said aperture being of multisided geometric configuration, said apertures being disposed in adjacent offset rows wherein each of the sides of the upper portions of said apertures, other than those in the peripheral rows on said base, define common walls with adjacent sides of the upper portions of adjacent apertures so that said apertures cooperate to define a honeycomb-like configuration in said base; and (b) a plurality of resiliently flexible spaced feet extending integrally downwardly from the underside of said base to maintain said base in slightly upwardly spaced relation to a supporting surface when positioned thereon, said feet having substantially flat bottom surfaces and being of elongated barbell-like sectional configuration wherein the transverse sectional dimensions of said feet are greater in the opposite end portions thereof than in the central portions thereof.
Claim 3
Dependent Claim
29 words
In the floor mat construction of claim 1, said feet being disposed so that adjacent feet are in spaced relation and at angles of approximately 60° with each other.
Claim 4
Dependent Claim
88 words
A floor mat construction comprising: (a) a base made of a rubberized material and having a plurality of apertures therethrough; and (b) a plurality of spaced feet which are resiliently flexible and extend integrally downwardly from the underside of said base, said feed being of elongated barbell-like sectional configuration wherein the transverse sectional dimensions of said feet are greater in the opposite end portions thereof than in the central portions thereof and having substantially flat bottom surfaces which engage said supporting surface when said mat is positioned thereon.
Claim 5
Dependent Claim
88 words
A floor mat construction comprising: (a) a base made of a rubberized material and having a plurality of apertures therethrough; and (b) a plurality of spaced feet which are resiliently flexible and extend integrally downwardly from the underside of said base, said feed being of elongated barbell-like sectional configuration wherein the transverse sectional dimensions of said feet are greater in the opposite end portions thereof than in the central portions thereof and having substantially flat bottom surfaces which engage said supporting surface when said mat is positioned thereon.
Claim 6
Dependent Claim
29 words
In the floor mat construction of claim 3, said feet being disposed so that adjacent feet are in spaced relation and at angles of approximately 60° with each other.
Claim 7
Dependent Claim
160 words
A floot mat construction comprising a base made of a rubberized material and having a plurality of apertures therethrough, the upper portions of said apertures being of multisided geometric configuration, the lower portions of said apertures being of downwardly and inwardly tapered substantially circular configuration, said apertures being disposed in adjacent offset rows wherein each of the sides of the upper portions of said apertures, other than those in the peripheral rows on said base, define common walls with adjacent sides of the upper portions of adjacent apertures so that the upper portions of said apertures cooperates to define a honeycomb-like configuration in the upper portion of said base and the inwardly tapered lower portions of said apertures provide increased strength in said base and increased supporting area on the underside of said base, and a plurality of spaced feet of elongated sectional configuration extending integrally downwardly from the underside of said base adjacent the lower portions of said apertures.
Claim 8
Dependent Claim
160 words
A floot mat construction comprising a base made of a rubberized material and having a plurality of apertures therethrough, the upper portions of said apertures being of multisided geometric configuration, the lower portions of said apertures being of downwardly and inwardly tapered substantially circular configuration, said apertures being disposed in adjacent offset rows wherein each of the sides of the upper portions of said apertures, other than those in the peripheral rows on said base, define common walls with adjacent sides of the upper portions of adjacent apertures so that the upper portions of said apertures cooperates to define a honeycomb-like configuration in the upper portion of said base and the inwardly tapered lower portions of said apertures provide increased strength in said base and increased supporting area on the underside of said base, and a plurality of spaced feet of elongated sectional configuration extending integrally downwardly from the underside of said base adjacent the lower portions of said apertures.
Claim 9
Dependent Claim
85 words
A floot mat construction comprising: (a) a base made of a rubberized material and having a plurality of apertures therethrough; and (b) a plurality of spaced feet which are slightly resiliently flexible and extend integrally downwardly from the underside of said base, said feet being of elongated sectional configuration and being disposed so that adjacent feet are at angles of approximately 60° with respect to each other, said feet having substantially flat bottom surfaces which engage said supporting surface when said mat is positioned thereon.
Claim 10
Dependent Claim
85 words
A floot mat construction comprising: (a) a base made of a rubberized material and having a plurality of apertures therethrough; and (b) a plurality of spaced feet which are slightly resiliently flexible and extend integrally downwardly from the underside of said base, said feet being of elongated sectional configuration and being disposed so that adjacent feet are at angles of approximately 60° with respect to each other, said feet having substantially flat bottom surfaces which engage said supporting surface when said mat is positioned thereon.
