Abstract
A universal hatch assembly for accessing an enclosure includes a door. The frame has an opening defined therein that is dimensioned and configured for mounting the door. A hinge apparatus allows pivotal movement of the door about a first axis between a first position in which the door covers the opening and a second open position. The interior side of the door has an elongated channel extending in substantially perpendicular relationship to the first axis. An operating lever for positioning the door, has first and second axial extremities. A first axial part of the operating lever is spaced apart from the second axial extremity which is pivotally connected to the frame. The second axial extremity is dimensioned and configured for sliding meshing engagement with the elongated channel. The hatch assembly includes a lift assembly to provide a favorable counterbalance for the door. The frame may include a peripheral groove extending around substantially the entire frame. At least one module selected from several different modules according to a given application has a mounting surface dimensioned and configured for engaging the peripheral groove.
