KR20000053989A - Manual ship propulsion device applying fish's tail fin - Google Patents

Abstract

PURPOSE: A manual ship propelling agent applied from fish caudal fin is provided to propel a ship in a high speed and allow a beginner to use the device easily. CONSTITUTION: A manual ship propelling agent applied from fish caudal fin has following structure. An angle concave(7) is formed on the upper portion of a shaft pipe case(2). The rear portion of the shaft pipe case(2) has a little crack fixed to a rear surface of a ship body(1) by bolt. A fish caudal fin(5) is assembled to a lower portion of a shaft(4). A shaft pipe(3) having angled edges is assembled to the middle of the shaft(4). A lever(6) is assembled to the upper portion of the shaft(4). A ship propelling device is formed when the integrally formed four members are fitted to the shaft pipe case(2). The fish caudal fin(5) is made of special rubber or special plastic goods thereby having a smooth elastic characteristics. Therefore, the manual ship propelling device applied from fish caudal fin elevate the speed of a ship highly.

Description

Manual Ship Propulsion Applied to Fish Tail Fin {.}

(1) Purpose of the invention

The present invention relates to a manual propulsion device of a small ship, but the conventional propulsion method of the vessel (1) is to propel the vessel by stirring the oars. In order to solve the various problems that the ship's propulsion speed is slow, the beginners are inconvenient to row the boat and the ship's propulsion speed is slow. It is an invention that can contribute to the development of small power lines because anyone can use it easily even for beginners.

(Code description of main parts of drawing)

(1) ships (2) tube cases (3) tube tubes (4) shafts (5) fish tail fins

(6) Levers (7) Grains (8) Grips (9) Oars (10) Labels (11) Surface

This configuration applies the principle that the fish runs at high speed by stirring the tail fins to the left and right, so that the propulsion speed of the ship can be greatly increased, and the lever 6 can be pushed and pulled when used. Anyone can easily operate the beginner, so it is a practical propulsion device, whereas the existing propulsion structure of the furnace (9) has a long part of the furnace (10) and a part of the handle (8) of the upper part of the furnace is short. (See Fig. 5) Much effort is required and propulsion is slow.

Principle of this configuration is the V-shaped angular groove (7) is formed on the upper part, the rear part of the shaft tube case (2) with a little gap is fixed to the center of the back of the vessel (see Fig. 4) with a bolt, 4 parts such as shaft, tail fin, and lever are assembled together into one object, and it is a propulsion device when it is placed inside the shaft case. And, by combining the shaft by protruding the angle of the V-shape on the upper portion of the shaft tube (3), the protruding angle is in close contact with the angle groove (7) is a perfect propulsion device. And the fish tail fin (5) is an invention that can produce a revolutionary propulsion speed when applied to ship propulsion by manufacturing a special rubber product or flexible plastic type flexible.

Many underdeveloped countries around the world are using conventional ship propulsion methods. Due to the present invention, there will be a lot of development in small non-powered ships, and it is considered to be in demand since it is a global invention.

Claims (1)

Angled grooves 7 are formed in the upper part of the shaft tube case 2, and in the rear part, bolts are fixed to the back of the hull 1 with a little gap, and a fish tail fin 5 is provided in the lower part of the shaft 4. Assemble the shaft tube (3) in the middle of the shaft is projected and the lever (6) is assembled at the top of the four parts consisting of one object in the tube case (2), the configuration and fish propulsion device Tail fin (5) is an invention that can increase the propulsion speed significantly because it is made of special rubber or special plastic products to apply a flexible fish tail fin to the propulsion device of the power line.
