Verkehrswege-Einrichtung und ihre Bestandteile

摘要

The cover consists of a surrounding frame (5) and a hinged lid (7). The hinge is equipped with a cam (29) which interacts with a counter-cam (22) on the frame to align the adjacent edges of the lid and frame when the lid is closed. The lid and frame also have interacting lateral guide surfaces, and the lid has an anti-lift pin (30) on each side adjacent to its hinge to prevent its hinge end from lifting when closed.
