ABSTRACT:
A hinged hatch assembly for the roof of a vehicle cab having an opening formed therein. The assembly includes a hatch which completely covers the opening when in a closed position. The hatch is connected to the roof of the vehicle cab by a pair of support arms. Each support arm contains a first and a second forked end whereby the first forked ends are pivotally attached by brackets to one side of the roof opening and the second forked ends are pivotally attached by brackets to the underside of the hatch. Sandwiched on each side of the brackets between the forked ends of the support arms are frictional elements which are spring loaded to impart a predetermined frictional force on the members. The frictional contact permits the hatch to be opened at various angles and at various positions relative to the plane of the roof and to remain in the desired position irrespective of any vibration or motion imparted into the vehicle. The hinged hatch roof assembly is capable of providing ventilation as well as serving as an escape route from the interior of the vehicle cab.
