Abstract:
A swimming pool bulkhead is disclosed. The bulkhead includes a substructure having a metallic frame, a pair of support assemblies mounted to opposite ends of the metallic frame of the substructure, and a superstructure having a non-metallic frame mounted to the substructure. A buoyancy chamber for a swimming pool bulkhead is also disclosed. The buoyancy chamber includes a substantially fluid-tight, cylindrical chamber, an air input conduit operatively connectable to a source of pressurized air, an air discharge conduit having an inlet in the chamber, and means for varying an elevation of a water level in the chamber to vary the buoyancy of the chamber. A method for controlling the buoyancy of a bulkhead is also provided.
