Abstract
Abstract A floor mat assembly is disclosed which is molded from resilient plastic material, and made up of only two different elements, mat modules and ramp strips. The mat module comprises a rectangular shape with two adjoining edges, each of the edges having an upper coupling edge flap with a row of downward directed projections, and two other adjoining edges, each of the other edges having a lower coupling edge flap with a row of vertical holes to couple with a row of projections on an upper coupling edge flap of a ramp strip or an adjoining mat module. The ramp strip comprises a tapered face with an upper coupling edge flap adjacent the tapered face, and a lower coupling edge flap joined by a severable link to the upper coupling edge flap, the lower coupling edge flap of the ramp strip to couple with an upper coupling edge flap of a mat module, and when the link is severed, the upper coupling edge flap of the ramp strip to couple with a lower coupling edge flap of a mat module.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
A floor mat assembly formed from two different components, mat modules and ramp strips, and molded from resilient plastic and having in combination at least one mat module which is coupled to at least one ramp strip the mat module comprising a rectangular shape with two adjoining edges, each of the edges having an upper coupling edge flap with a row of downward directed projections, and two other adjoining edges, each of the other edges having a lower coupling edge flap with a row of vertical holes to couple with a row of projections on an upper coupling edge flap of a ramp strip or an adjoining mat module, the ramp strip comprising a tapered face with an upper coupling edge flap adjacent the tapered face, and a lower coupling edge flap joined by a severable link to the upper coupling edge flap, the lower coupling edge flap of the ramp strip to couple with an upper coupling edge flap of a mat module, and when the link is severed, the upper coupling edge flap of the ramp strip to couple with a lower coupling edge flap of a mat module.
Claim 2
Dependent Claim
191 words
A floor mat assembly formed from two different components, mat modules and ramp strips, and molded from resilient plastic and having in combination at least one mat module which is coupled to at least one ramp strip the mat module comprising a rectangular shape with two adjoining edges, each of the edges having an upper coupling edge flap with a row of downward directed projections, and two other adjoining edges, each of the other edges having a lower coupling edge flap with a row of vertical holes to couple with a row of projections on an upper coupling edge flap of a ramp strip or an adjoining mat module, the ramp strip comprising a tapered face with an upper coupling edge flap adjacent the tapered face, and a lower coupling edge flap joined by a severable link to the upper coupling edge flap, the lower coupling edge flap of the ramp strip to couple with an upper coupling edge flap of a mat module, and when the link is severed, the upper coupling edge flap of the ramp strip to couple with a lower coupling edge flap of a mat module.
Claim 3
Dependent Claim
71 words
The floor mat assembly according to claim 1, wherein the ramp strip has a severable triangular shaped corner element at each end, the triangular shaped corner element being severed for ramp strips positioned side by side in a straight line and joining with a triangular shaped corner element of an adjoining ramp strip positioned in a corner relationship such that a ramp is formed at a corner of a mat module.
Claim 4
Dependent Claim
50 words
The floor mat assembly according to claim 1 wherein the mat module has a grid pattern of intersecting members, the members intersecting at nodes forming holes through the mat module between the members, the nodes each having a space on the bottom surface of the modular mat to permit drainage.
Claim 5
Dependent Claim
18 words
The floor mat assembly according to claim 3 wherein the members intersect perpendicularly and the holes are square.
Claim 6
Dependent Claim
34 words
The floor mat assembly according to claim 3 wherein the ramp strip has a grid pattern of intersecting members with square holes therebetween having substantially the same dimensions as those in the mat member.
Claim 7
Dependent Claim
34 words
The floor mat assembly according to claim 1 wherein the projections in each of the upper coupling edge flaps snap into the vertical holes in the lower coupling edge flaps and are removable therefrom.
