Abstract
Abstract A stable floor for animals which is in structural combination with a floor covering sheet having at least two layers: a compressible sublayer of a resilient and highly porous filamentary matting partly embedded in a top layer which is impermeable to moisture. The floor covering sheet provides good insulation and has dimensional stability so as to remain resilient over a prolonged period of time.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
116 words
In structural combination with a stable floor for animals, a soft and resilient floor covering sheet comprising a highly porous, compressible sublayer in placement on said floor and a polymeric top layer which is impermeable to moisture, said compressible sublayer consisting essentially of a matting sheet composed of continuous, looped synthetic polymeric filaments intersecting one another and fused at their points of intersection, said filaments having a diameter of 0.4 to 2.5 mm, said matting having in its normal non-compressed state a porosity exceeding 90% with its porous structure being sufficiently open to prevent any accumulation of capillary moisture, and the upper face of said matting being at least partly embedded in said impermeable top layer.
Claim 2
Dependent Claim
116 words
In structural combination with a stable floor for animals, a soft and resilient floor covering sheet comprising a highly porous, compressible sublayer in placement on said floor and a polymeric top layer which is impermeable to moisture, said compressible sublayer consisting essentially of a matting sheet composed of continuous, looped synthetic polymeric filaments intersecting one another and fused at their points of intersection, said filaments having a diameter of 0.4 to 2.5 mm, said matting having in its normal non-compressed state a porosity exceeding 90% with its porous structure being sufficiently open to prevent any accumulation of capillary moisture, and the upper face of said matting being at least partly embedded in said impermeable top layer.
Claim 3
Dependent Claim
23 words
The structural combination claimed in claim 1 wherein the lower face of said matting away from the top layer has a waffle-like structure.
Claim 4
Dependent Claim
27 words
The structural combination claimed in claim 1 which includes an overlay secured onto said impermeable top layer and consisting of a nonwoven of synthetic filaments or fibers.
Claim 5
Dependent Claim
21 words
The structural combination claimed in claim 1 wherein said floor covering sheet is installed substantially without seams over the stable floor.
Claim 6
Dependent Claim
41 words
The structural combination claimed in claim 1 wherein the impermeable top layer is formed by a PVC which receives the embedded matting to a depth of about 1 to 5 mm for a matting thickness of about 10 to 40 mm.
Claim 7
Dependent Claim
31 words
The structural combination claimed in claim 1 wherein the matting filaments are composed of a synthetic, fibrous polymer selected from the group consisting of polycaprolactam, polyhexamethylene adipamide, polyethylene terephthalate and polypropylene.
Claim 8
Dependent Claim
15 words
The structural combination claimed in claim 6 wherein the matting filaments consist essentially of polycaprolactam.
