Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 234 words
A flocked mat especially suited for pedestrain traffic particularly to wipe wet and/or dirty feet, said mat comprising: (1) a web formed of a three-dimensional, lofty, open, porous, network comprising strands of water-resistant, organic polymer material generally defining connecting open spaces capable of receiving dirt, said web being at least 0.5 cm in thickness, having a void volume of at least about 75% and being resiliently compressible underfoot by about at least 10% of its thickness; (2) a continuous backing layer of organic polymeric material having a thickness on the order of 0.2 to 2.5 mm attached to one major surface of said web and forming one major surface of said mat; (3) a resinous water-resistant bonding adhesive substantially entirely coating the surfaces of said strands of said network without filling said open spaces substantially throughout said web; and (4) water-resistant, wear-resistant organic textile flocking material having a denier in the range of about 0.5 to 25 and a length in the range of about 0.25 to 2.5 mm and being uniformly distributed substantially throughout said web and adhesively bonded to said web by said resinous bonding adhesive substantially entirely covering the surfaces of each of said strands of said network substantially without filling said open spaces to provide a flocked web capable of providing a wiping surface for dirt and water, receiving, obscuring and holding dirt therein and facilitating the evaporation of water.
Claim 2
Dependent Claim 234 words
A flocked mat especially suited for pedestrain traffic particularly to wipe wet and/or dirty feet, said mat comprising: (1) a web formed of a three-dimensional, lofty, open, porous, network comprising strands of water-resistant, organic polymer material generally defining connecting open spaces capable of receiving dirt, said web being at least 0.5 cm in thickness, having a void volume of at least about 75% and being resiliently compressible underfoot by about at least 10% of its thickness; (2) a continuous backing layer of organic polymeric material having a thickness on the order of 0.2 to 2.5 mm attached to one major surface of said web and forming one major surface of said mat; (3) a resinous water-resistant bonding adhesive substantially entirely coating the surfaces of said strands of said network without filling said open spaces substantially throughout said web; and (4) water-resistant, wear-resistant organic textile flocking material having a denier in the range of about 0.5 to 25 and a length in the range of about 0.25 to 2.5 mm and being uniformly distributed substantially throughout said web and adhesively bonded to said web by said resinous bonding adhesive substantially entirely covering the surfaces of each of said strands of said network substantially without filling said open spaces to provide a flocked web capable of providing a wiping surface for dirt and water, receiving, obscuring and holding dirt therein and facilitating the evaporation of water.
Claim 3
Dependent Claim 13 words
The mat of claim 1 wherein said three-dimensional web is a recticulated foam.
Claim 4
Dependent Claim 26 words
The mat of claim 1 wherein said three-dimensional web is formed of a multiplicity of continuous undulated filaments autogenously bonded together at points of mutual contact.
Claim 5
Dependent Claim 28 words
The mat of claim 3 wherein said web of undulated filaments has a greater filament density adjacent said backing layer than in the remaining portion of said web.
Claim 6
Dependent Claim 23 words
The mat of claim 1 wherein said three-dimensional web is formed of crimped stable fibers adhesively bonded together at points of mutual contact.
Claim 7
Dependent Claim 18 words
The mat of claim 1 wherein said three-dimensional web is open looped pile supported by a base layer.
Claim 8
Dependent Claim 23 words
The mat of claim 1 wherein said organic polymeric material is selected from the group consisting of polyamide, polyvinylchloride, polyester, polyurethane and polycarbonate.
Claim 9
Dependent Claim 30 words
The mat of claim 1 wherein said water-resistant organic textile flocking material is formed from an organic material selected from the group consisting of nylon, rayon, polyester and mixtures thereof.
Claim 10
Dependent Claim 14 words
The mat of claim 1 wherein said backing layer comprises a closed cell foam.
Claim 11
Dependent Claim 14 words
The mat of claim 1 wherein said backing layer comprises an open cell foam.
Claim 12
Dependent Claim 30 words
The mat of claim 1 wherein said backing layer comprises a foam formed of a polymeric material selected from the group consisting of polyurethane, polyvinyl chloride, polyester, polypropylene and polyethylene.
