发明名称 Motorized tubular flotation apparatus
摘要 A propulsion apparatus is mounted on at least one end of a flexible tubular flotation member which is mountable about the body of the user. The propulsion apparatus is capable of propelling the tubular member and the user in the water. In one embodiment, a housing containing a motor driven propeller is fixedly mountable over one end of the tubular member. A guard containing an open mesh surrounds the propeller. In another embodiment, the housing and the propulsion means are mounted in a bore in the end of the tubular member, with the propeller projecting outward from the end of the tubular member.
