TODAY’S PATENT- PADDLES FOR BOATS
The Paddles for boats were invented by Douglas B.I. Proctor on the 18th November 1980, bearing patent number US4233925A.
This invention relates to paddles and is particularly concerned with single-handed paddles for use with boats. This invention is a plastic paddle of unitary construction defining a hand grip with a wrist engageable portion at one end, and a blade portion at the opposite end, which blade has a tapered cross sectional shape with flanges defined along its marginal edges to achieve maximum strength from a minimum material, and the paddle material itself being formed of plastic to a uniform thickness for economy in manufacture.
It is a general object of the present invention to provide a paddle, for use primarily with boats, which can be easily formed in plastics material in one manufacturing process, can be comfortably used with only the blade-part of the paddle immersed and can be conveniently stowed on a small boat.
