Abstract
Abstract An improved floor mat which may be readily folded 180° upon itself. The mat includes a semi-rigid plastic surface with a transversely extending plastic strip laminated into its undersurface. The plastic strip is formed of material relatively more flexible than the overlying mat material. The mat is provided with a transverse slit overlying the laminated plastic strip which preferably extends downwardly to the upper surface of the plastic strip whereby the floor mat may be readily folded along the flexible plastic strip.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
192 words
An improved floor mat, comprising: an elongated web means of semi-rigid, liquid-impervious, plastic material having a predetermined durometer rating on a Rockwell C scale sufficiently high to provide a durable wear surface for the mat during normal use; plastic strip means embedded into said web means and laminated thereto while the web means was in molden condition to thereby form an integral web exclusive of any extraneous bonding means or medium, said strip means being formed of relatively flexible, liquid-impervious, plastic material having a predetermined durometer rating on a Rockwell A scale less than the durometer rating of said web means to provide said flexibility; and slit means in the side of said web means opposite from said strip means and extending through said web means to the adjacent side surface of said strip means, said slit means being disposed generally opposite and parallel to said strip means whereby said floor mat may be readily folded along said slit means substantially 180° upon itself, the strip means being laminated integrally into said web means so that the adjacent outer, exposed sides of said web means and said strip means are substantially coplanar.
Claim 2
Dependent Claim
192 words
An improved floor mat, comprising: an elongated web means of semi-rigid, liquid-impervious, plastic material having a predetermined durometer rating on a Rockwell C scale sufficiently high to provide a durable wear surface for the mat during normal use; plastic strip means embedded into said web means and laminated thereto while the web means was in molden condition to thereby form an integral web exclusive of any extraneous bonding means or medium, said strip means being formed of relatively flexible, liquid-impervious, plastic material having a predetermined durometer rating on a Rockwell A scale less than the durometer rating of said web means to provide said flexibility; and slit means in the side of said web means opposite from said strip means and extending through said web means to the adjacent side surface of said strip means, said slit means being disposed generally opposite and parallel to said strip means whereby said floor mat may be readily folded along said slit means substantially 180° upon itself, the strip means being laminated integrally into said web means so that the adjacent outer, exposed sides of said web means and said strip means are substantially coplanar.
Claim 3
Dependent Claim
34 words
An improved floor mat as set forth in claim 1 wherein the thickness of said strip means is approximately one-half the thickness of said web means at a location removed from said strip means.
Claim 4
Dependent Claim
57 words
An improved floor mat as set forth in claim 1 wherein said web means material comprises semi-rigid plastic material having a durometer rating on the order of 80-95 on a Rockwell C scale and said strip means material comprises a relatively flexible plastic having a durometer rating on the order of 50-70 on a Rockwell A scale.
