Abstract
In order to provide a relatively inexpensive water-tight telescopic enclosure which can extend automatically upon demand, a tubular extension piece is reciprocally mounted on a container-like hook box structure. A tube seal which interconnects the hook box and the tubular extension provides a watertight connection between the two members and also provides an air space in a folded portion in which air can collect and produce buoyancy as the hook box is lowered into water. The tubular extension also has a larger cross-sectional area than the hook box and thus produces additional buoyancy. When the hook box is lowered into water the extension piece automatically floats upwardly to prevent the intrusion of water into the interior of the hook box and thus prevent contamination of pieces of apparatus enclosed therein.
