ABSTRACT:
Apparatus for controlling opening and closing movement of a door including manual actuation for opening the door and then biasing the door toward its closed position. A device for slowing and impeding movement of the door in the closing direction includes a flexible sealed container with a high viscosity fluid arranged to reciprocate in one direction responsive to opening the door and in the opposite direction to closing the door. A channel has a first section and a second section with the side walls and a sloping bottom wall between the sections providing a roller guide. A roller in contact with the sealed container is freely movable and has rotary and reciprocating motion within the roller guide of the stationary channel upon engagement with the flexible sealed container. Movement of the door to its open position will move the roller into the first channel section and movement of the door to its closed position moves the roller into the second section causing the sealed container to be deformed by the roller and movement of the door to its closed position is slowed and impeded by reason of viscosity of the material in the sealed container.
