Abstract
Abstract A flexible matting for use at an entrance porch, corridor, veranda, pool-side, interior floor of automobiles, etc. This matting consists of a base on which tread bars and rows of ridges bearing piles are arranged in a definite direction with appropriate spacings between them so that the mud adhered to shoes can be removed by the piles and collected in the grooves formed between the ridges. Thus, the removal of mud from the present matting is very easy as compared with a conventional one.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
140 words
A flexible matting adapted for cleaning shoes comprising a one-piece mat of integrally molded flexible material inculding a base sheet, a plurality of tread bars substantially parallel to each other integrally molded to said base sheet at intervals shorter than the width of shoes, a plurality of ridges having piles thereon integrally molded to said base sheet and arranged at approximately equal intervals between and parallel to said tread bars with the width of the ridges narrower than the width of the tread bars and forming grooves between said ridges and said ridges and tread bars, whereby said ridges and piles have a flexibility requiring the support of said tread bars against an excessive pressing force on said ridges and piles, the top of said piles being approximately 2 to 15mm higher than the upper surface of said tread bars.
Claim 2
