Abstract
A camera water-tight housing includes a hollow body member having a rectangular rear access opening delineated by the rear borders of the body member walls and a rectangular transparent lid having grooves formed in its inside face along its long sides. Each groove includes opposing faces, the inside faces being stepped and a resilient packing engages the face stepped portions and is retained therein by the borders of a pressure plate secured to the lid inside face. In the housing closed condition, the wall end borders along the opening long sides engages the lid grooves between the backing and the groove outer faces to compress the packing and effects a water-tight seal. Locking members are provided on the body member end walls and include hook portions for engaging tabs projecting from the lid to lock it in its closed position and cams for engaging the tabs and ejecting the lid when the members are rotated to separate the hook portions from the tabs. A camera mechanism is located in the housing and includes separate covers for the film and battery chambers, the covers being locked in closed position by the lid carried pressure plate in the housing closed condition.
