Abstract: A grid plate includes a top side having a non-slip surface having openings to permit the growth of grass. At two sides which are arranged at an angle with respect to one another, the grid plate is provided with step-shaped lateral side walls. An abutment is molded into the vertical stepped wall, this abutment being formed by wall apertures placed into the step-shaped lateral side wall. A horizontal stepped side is used for supporting the side edges which project beyond the ribbing of the bottom side. At the lateral edge, plug-in connections are molded on, which, in the manner of hinges, lock into the wall apertures of an adjacent grid plate. The lateral edge has hooks which point downward and which, during the hinge movement, when the grid plates are emplaced, engage behind the wall of the wall apertures.

Abstract: A grid plate of plastic material, with a rough, slippage-impairing top side and a rib-reinforced bottom side. The individual grid plates are kept together by a lockable, but again disconnectable, plug-in connection. The grid plates serve as fastening elements for parking places, road embankments, road ramps, and the like.
