Abstract

A locking device for hinged round roadway inspection covers (1) has a double T-shaped housing (3) in the frame (2) consisting of two horizontal slots joined by a vertical part. A blade type hinge T-shaped, fixed to the cover (1), has its hemispherical end held in the upper slot of the housing when the cover is closed. When open at 90 degrees the hinge end is held by a stop between upper and lower slots and for 130 to 140 degrees opening it sits in the upper slot bearing against its rounded edge. USE/ADVANTAGES - Improved design with simplified hinge.
