Locking device for a shaft covering or a road gulley

摘要

The closure device (1) has a frame (11) and a closure element (13) that is movable from a closing position into an opening position. A retainer (30) is formed at the frame and forms a hinge-type connection (20) with a pivot axle (21) that is arranged at the closure element. The axle is fastened to the closure element over a spring element (22) as a single piece. A recess is formed at the frame for completely accommodating the spring element in the closing condition of the closure element. A locking pin (42) is formed at the closure element.
