发明名称 Flotation device for supporting a person in water
摘要 A flotation device for supporting a person in water comprises an elongate tubular frame including at least one body-support member, and front and rear float assemblies mounted on the frame. The rear float assembly comprises two float elements spaced apart transversely of the elongate frame, and the float elements are so disposed that, when the device is floating in the water, the body-support member is below water level, so that a person using the device is partly in the water.
