Abstract

Oppfinnelsen vedrører et lokk som er tilpasset for. åpning og lukking av et mannhull, hvor nevnte lokk består av et bevegelig lokk (1) og et lokkfundament (2) som er forbundet med hverandre ved hjelp av en aksel (11) laget av en aluminiumbronselegering. I henhold til oppfinnelsen er det bevegelige lokk (1) forbundet med lokkfundamentet (2) ved hjelp av i det minste én aksel (11) som løper gjennom i det minste én første hengsledel (16) som er festet til det bevegelige lokk (1) og i det minste to andre hengsledeler (10) som er festet til lokkfundamentet (2), hvor nevnte første hengsledel (16) er festet vinkelrett på de andre hengsledeler (10). På denne måte er det mulig å fremstille robuste mannlokk som gir god komfort til en bilfører siden det bevegelige lokk kan fremstilles på en slik måte at avstanden (20) mellom det bevegelige lokks (1) ytre kant og lokkfundamentet (2) kan minimeres.The invention relates to a lid which is adapted for. opening and closing of a manhole, said lid consisting of a movable lid (1) and a lid foundation (2) which are connected to each other by means of a shaft (11) made of an aluminum bronze alloy. According to the invention, the movable lid (1) is connected to the lid foundation (2) by means of at least one shaft (11) which runs through at least one first hinge part (16) which is attached to the movable lid (1). and at least two second hinge members (10) attached to the lid foundation (2), said first hinge member (16) being attached perpendicular to the second hinge members (10). In this way it is possible to produce robust male lids which provide good comfort to a driver since the movable lid can be manufactured in such a way that the distance (20) between the outer edge of the movable lid (1) and the lid foundation (2) can be minimized.
