ABSTRACT:
A simple, compact counterweight mechanism for a lid for a sub-surface container. A straight rigid beam extends from front to rear within the container. Front portions of the beam are connected to the overlying lid, middle portions of the beam are pivotally connected to the container and rear portions of the beam are pivotally connected to a pair of rearwardly extending control arms, which are pivotally connected at their rear to a depending counterweight. A compression spring is mounted on the beam beneath the control arms, so that as the front of the lid is lifted to open the lid and pivot the lid and the front portions of the beam upwardly and rearwardly about the middle portions of the beam and pivot the rear portions of the beam, together with the control arms and the counterweight, downwardly and frontally about the middle portions of the beam, the spring keeps the pivotal connection of the counterweight and the control arms, together with the vertically aligned center of gravity of the counterweight, located rearwardly of the pivotal connection of the middle portions of the beam and the container.
