Stair nosing.

摘要

A stair nosing 10 is constituted by a flat tire frame 11 for lying on a tread of a stair, a non-skid flat tire 12 adapted to be snappedly engaged to the flat tire frame 11, and a tongue-shaped projector 15 for the engaging portion of the flat tire frame 11 and the non-skid flat tire 12. The non-skid flat tire 12 comprises a connecting plate' 13 of rigid synthetic resin having the flange 24 with rib 25 at one edge and a non-skid flat tread 14 of flexible synthetic resin integrally formed on the upper surface of the connecting plate 13.

The tongue-shaped projector 15 is integrally formed with the non-skid flat tread 14 so as to cover the engaging portion spacedly located from a riser of the stair when the non-skid flat tire 12 is secured to the flat tire frame 11.
