发明名称 Folding snorkel
摘要 The instant invention is a skin diving snorkel having a conduit with an end above the water surface, and an underwater end that terminates in a mouthpiece. The mouthpiece provides a flow path between the conduit and the interior of the diver's mouth. The conduit is divided along its length into two or more segments. The end of one segment slips with close clearance into a mating socket of the adjacent end of the next segment. The close fit of mating surfaces provides a substantially watertight joint. A small diameter elastic cord threaded, under tension, inside the conduit joins the conduit segments. One end of the elastic cord is attached to the conduit near the above water opening. The other end of the elastic cord is attached to the conduit near the mouthpiece opening. The elastic cord stretches when the segments are separated, and functions as a hinge that allows the separated segments to be placed side by side even though they remain connected by the elastic cord. The elastic cord holds the segments firmly together when joined, and maintains the proper sequential and alignment relationship between the segments when the segments are separated.
