Patent ID: 7007986

Claim:
A selectively openable closure assembly including a handhold frame mounted in a wall of a hollow housing having an inner chamber and an inner surface and an outer surface between which an access opening extends to permit access to the inner chamber from a location external to the hollow housing, a cover positionable over the access opening for closing the access opening and being movable from the closed position to an open position spaced from the access opening so as to permit access to the inner chamber, a first connector removably mounted on the handhold frame and engaging a first portion of the cover and a portion of the handhold frame for holding the first portion of the cover in a fixed position relative to the frame, a second connector spaced from the first connector and engaging the cover and the handhold frame to cooperate with the first connector when the first connector is mounted on the handhold frame for maintaining the cover in a closed position over the access opening, wherein disconnection of the first connector from the frame permits limited movement of the cover outwardly of the access opening followed by pivotal movement of the cover about the second connector out of alignment with the access opening while retaining a tethered connection of the cover to the frame so as to prevent the unauthorized removal of the cover while permitting unrestricted access through the access opening, and wherein the second connector is an unthreaded pin mounted for axial movement in an aperture in the handhold frame, and additionally including a spring providing a biasing force urging the unthreaded pin inwardly of the frame and further including a force applying surface on the unthreaded pin engaging the cover so that the force provided by the spring tends to urge the cover inwardly toward the handhold frame.
