ABSTRACT:
An automatically openable lid for a receptacle structure has a safety device for preventing any accident in the presence of an obstacle in the range of opening and closing movements of the lid. The device includes a safety guard extending around a front surface of the lid and beyond a rear surface thereof. The guard is mounted on the lid in a semi-fixed manner such that the guard is normally kept immovable relative to the lid during the movement thereof and such that the guard is pivotally movable relative to the lid when the guard is hit by any obstacle during the movement of the lid. Responsive to the movement of the guard relative to the lid, a detecting means is operable to energize a brake for stopping the movement of the lid.
