Abstract

Cover for drainage channels on roads or runways comprises a minimum of two rectangular metal grills hinged together by a series of tenon and mortise joints to form a chain. The lateral tenons have flat upper surfaces which increase the supporting area, and the upper surface of a row of tenons belonging to one grill is at a slightly different height in relation to the upper surface of the tenons of the adjoining grill. When a wheel rests on two grills at their hinge-point, the supporting areas of the tenons lessen considerably the overhang and the difference in height between tenons of adjacent grills means that when a wheel passes from one to another, any possibility of tipping up of the cover is avoided.
