Abstract

The invention relates to the installation of stair mats on stairs in a manner such that the edge cover is formed of a flexible synthetic resin or flexible rubber and a tread mat are adapted to the stairs, being adjacent to each other; the front edge of the tread mat being set on a tread side fixing tongue of the edge cover and the front edge of the tread mat being fixed on the tread side fixing tongue of the edge cover by an adhesive or by stitching.

A thin tread side fixing tongue is integrally and horizontally extended from the rear portion of an edge bead cushion of the edge cover.

Claims

1. A stair mat comprising:

an edge cover being formed of flexible synthetic resin, including an edge bead cushion having a hollow portion therein extended along the length of the edge bead cushion and a non-skid surface portion as serrations along the cross-section on the upper surface thereof, said edge cover being adapted to be secured to the forward edge of a step;

an edge base integrally set on the under surface of the edge bead cushion formed of synthetic resin having greater rigidity than that of the edge bead cushion and adapted to be formed on the edge of a step;

a tread side fixing tongue integrally and horizontally extended from the rear edge of the edge base formed of a synthetic resin having greater rigidity than that of the edge bead cushion and adapted to be secured to the tread of a step;

a riser side fixing tongue integrally and downwardly extended from the front edge of the edge base formed of a synthetic resin having greater rigidity than that of the edge bead cushion and adapted to be secured to the riser of a step; and

a tread mat of carpet being fixed on the tread side fixing tongue, and adapted to be secured on the tread of a step.

2. A stair mat as claimed in claim 1, in which the edge bead cushion has a shield tongue integrally and downwardly extended from the front side of the edge bead cushion formed of a flexible resin and integrally fixed on the front surface of the riser side fixing tongue.
